-Notes about building lws
-========================
-
-
-@section cm Introduction to CMake
-
-CMake is a multi-platform build tool that can generate build files for many
-different target platforms. See more info at http://www.cmake.org
-
-CMake also allows/recommends you to do "out of source"-builds, that is,
-the build files are separated from your sources, so there is no need to
-create elaborate clean scripts to get a clean source tree, instead you
-simply remove your build directory.
-
-Libwebsockets has been tested to build successfully on the following platforms
-with SSL support (for OpenSSL/wolfSSL/BoringSSL):
-
-- Windows (Visual Studio)
-- Windows (MinGW)
-- Linux (x86 and ARM)
-- OSX
-- NetBSD
-
-
-@section build1 Building the library and test apps
-
-The project settings used by CMake to generate the platform specific build
-files is called [CMakeLists.txt](CMakeLists.txt). CMake then uses one of its "Generators" to
-output a Visual Studio project or Make file for instance. To see a list of
-the available generators for your platform, simply run the "cmake" command.
-
-Note that by default OpenSSL will be linked, if you don't want SSL support
-see below on how to toggle compile options.
-
-
-@section bu Building on Unix:
-
-1. Install CMake 2.8 or greater: http://cmake.org/cmake/resources/software.html
- (Most Unix distributions comes with a packaged version also)
-
-2. Install OpenSSL.
-
-3. Generate the build files (default is Make files):
-```
- $ cd /path/to/src
- $ mkdir build
- $ cd build
- $ cmake ..
-```
-
-4. Finally you can build using the generated Makefile:
-```
- $ make && sudo make install
-```
-**NOTE**: The `build/`` directory can have any name and be located anywhere
- on your filesystem, and that the argument `..` given to cmake is simply
- the source directory of **libwebsockets** containing the [CMakeLists.txt](CMakeLists.txt)
- project file. All examples in this file assumes you use ".."
-
-**NOTE2**:
-A common option you may want to give is to set the install path, same
-as --prefix= with autotools. It defaults to /usr/local.
-You can do this by, eg
-```
- $ cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr .
-```
-
-**NOTE3**:
-On machines that want libraries in lib64, you can also add the
-following to the cmake line
-```
- -DLIB_SUFFIX=64
-```
-
-**NOTE4**:
-If you are building against a non-distro OpenSSL (eg, in order to get
-access to ALPN support only in newer OpenSSL versions) the nice way to
-express that in one cmake command is eg,
-```
- $ cmake .. -DOPENSSL_ROOT_DIR=/usr/local/ssl \
- -DCMAKE_INCLUDE_DIRECTORIES_PROJECT_BEFORE=/usr/local/ssl \
- -DLWS_WITH_HTTP2=1
-```
-
-When you run the test apps using non-distro SSL, you have to force them
-to use your libs, not the distro ones
-```
- $ LD_LIBRARY_PATH=/usr/local/ssl/lib libwebsockets-test-server --ssl
-```
-
-To get it to build on latest openssl (2016-04-10) it needed this approach
-```
- cmake .. -DLWS_WITH_HTTP2=1 -DLWS_OPENSSL_INCLUDE_DIRS=/usr/local/include/openssl -DLWS_OPENSSL_LIBRARIES="/usr/local/lib64/libssl.so;/usr/local/lib64/libcrypto.so"
-```
-
-Mac users have reported
-
-```
- $ export OPENSSL_ROOT_DIR=/usr/local/Cellar/openssl/1.0.2k; cmake ..; make -j4
-```
-
-worked for them when using "homebrew" OpenSSL
-
-**NOTE5**:
-To build with debug info and _DEBUG for lower priority debug messages
-compiled in, use
-```
- $ cmake .. -DCMAKE_BUILD_TYPE=DEBUG
-```
-
-**NOTE6**
-To build on Solaris the linker needs to be informed to use lib socket
-and libnsl, and only builds in 64bit mode.
-
-```bash
- $ cmake .. -DCMAKE_C_FLAGS=-m64 -DCMAKE_EXE_LINKER_FLAGS="-lsocket -lnsl"
-```
-
-4. Finally you can build using the generated Makefile:
-
-```bash
- $ make
- ```
-
-@section lcap Linux Capabilities
-
-On Linux, lws now lets you retain selected root capabilities when dropping
-privileges. If libcap-dev or similar package is installed providing
-sys/capabilities.h, and libcap or similar package is installed providing
-libcap.so, CMake will enable the capability features.
-
-The context creation info struct .caps[] and .count_caps members can then
-be set by user code to enable selected root capabilities to survive the
-transition to running under an unprivileged user.
-
-@section cmq Quirk of cmake
-
-When changing cmake options, for some reason the only way to get it to see the
-changes sometimes is delete the contents of your build directory and do the
-cmake from scratch.
-
-deleting build/CMakeCache.txt may be enough.
-
-
-@section cmw Building on Windows (Visual Studio)
-
-1. Install CMake 2.6 or greater: http://cmake.org/cmake/resources/software.html
-
-2. Install OpenSSL binaries. http://www.openssl.org/related/binaries.html
-
- (**NOTE**: Preferably in the default location to make it easier for CMake to find them)
-
- **NOTE2**:
- Be sure that OPENSSL_CONF environment variable is defined and points at
- <OpenSSL install location>\bin\openssl.cfg
-
-3. Generate the Visual studio project by opening the Visual Studio cmd prompt:
-
-```
- cd <path to src>
- md build
- cd build
- cmake -G "Visual Studio 10" ..
-```
-
- (**NOTE**: There is also a cmake-gui available on Windows if you prefer that)
-
- **NOTE2**:
- See this link to find out the version number corresponding to your Visual Studio edition:
- http://superuser.com/a/194065
-
-4. Now you should have a generated Visual Studio Solution in your
- `<path to src>/build` directory, which can be used to build.
-
-5. Some additional deps may be needed
-
- - iphlpapi.lib
- - psapi.lib
- - userenv.lib
-
-6. If you're using libuv, you must make sure to compile libuv with the same multithread-dll / Mtd attributes as libwebsockets itself
-
-
-@section cmwmgw Building on Windows (MinGW)
-
-1. Install MinGW: http://sourceforge.net/projects/mingw/files
-
- (**NOTE**: Preferably in the default location C:\MinGW)
-
-2. Fix up MinGW headers
-
- a) If still necessary, sdd the following lines to C:\MinGW\include\winsock2.h:
-```
- #if(_WIN32_WINNT >= 0x0600)
-
- typedef struct pollfd {
-
- SOCKET fd;
- SHORT events;
- SHORT revents;
-
- } WSAPOLLFD, *PWSAPOLLFD, FAR *LPWSAPOLLFD;
-
- WINSOCK_API_LINKAGE int WSAAPI WSAPoll(LPWSAPOLLFD fdArray, ULONG fds, INT timeout);
-
- #endif // (_WIN32_WINNT >= 0x0600)
-```
-
- Update crtdefs.h line 47 to say:
-
-```
- typedef __int64 ssize_t;
-```
-
- b) Create C:\MinGW\include\mstcpip.h and copy and paste the content from following link into it:
-
- https://github.com/Alexpux/mingw-w64/blob/master/mingw-w64-headers/include/mstcpip.h
-
-3. Install CMake 2.6 or greater: http://cmake.org/cmake/resources/software.html
-
-4. Install OpenSSL binaries. http://www.openssl.org/related/binaries.html
-
- (**NOTE**: Preferably in the default location to make it easier for CMake to find them)
-
- **NOTE2**:
- Be sure that OPENSSL_CONF environment variable is defined and points at
- <OpenSSL install location>\bin\openssl.cfg
-
-5. Generate the build files (default is Make files) using MSYS shell:
-```
- $ cd /drive/path/to/src
- $ mkdir build
- $ cd build
- $ cmake -G "MSYS Makefiles" -DCMAKE_INSTALL_PREFIX=C:/MinGW ..
-```
- (**NOTE**: The `build/`` directory can have any name and be located anywhere
- on your filesystem, and that the argument `..` given to cmake is simply
- the source directory of **libwebsockets** containing the [CMakeLists.txt](CMakeLists.txt)
- project file. All examples in this file assumes you use "..")
-
- **NOTE2**:
- To generate build files allowing to create libwebsockets binaries with debug information
- set the CMAKE_BUILD_TYPE flag to DEBUG:
-```
- $ cmake -G "MSYS Makefiles" -DCMAKE_INSTALL_PREFIX=C:/MinGW -DCMAKE_BUILD_TYPE=DEBUG ..
-```
-6. Finally you can build using the generated Makefile and get the results deployed into your MinGW installation:
-
-```
- $ make
- $ make install
-```
-
-@section optee Building for OP-TEE
-
-OP-TEE is a "Secure World" Trusted Execution Environment.
-
-Although lws is only part of the necessary picture to have an https-enabled
-TA, it does support OP-TEE as a platform and if you provide the other
-pieces, does work very well.
-
-Select it in cmake with `-DLWS_PLAT_OPTEE=1`
-
-
-@section cmco Setting compile options
-
-To set compile time flags you can either use one of the CMake gui applications
-or do it via the command line.
-
-@subsection cmcocl Command line
-
-To list available options (omit the H if you don't want the help text):
-
- cmake -LH ..
-
-Then to set an option and build (for example turn off SSL support):
-
- cmake -DLWS_WITH_SSL=0 ..
-or
- cmake -DLWS_WITH_SSL:BOOL=OFF ..
-
-@subsection cmcoug Unix GUI
-
-If you have a curses-enabled build you simply type:
-(not all packages include this, my debian install does not for example).
-
- ccmake
-
-@subsection cmcowg Windows GUI
-
-On windows CMake comes with a gui application:
- Start -> Programs -> CMake -> CMake (cmake-gui)
-
-
-@section wolf wolfSSL/CyaSSL replacement for OpenSSL
-
-wolfSSL/CyaSSL is a lightweight SSL library targeted at embedded systems:
-https://www.wolfssl.com/wolfSSL/Products-wolfssl.html
-
-It contains a OpenSSL compatibility layer which makes it possible to pretty
-much link to it instead of OpenSSL, giving a much smaller footprint.
-
-**NOTE**: wolfssl needs to be compiled using the `--enable-opensslextra` flag for
-this to work.
-
-@section wolf1 Compiling libwebsockets with wolfSSL
-
-```
- cmake .. -DLWS_USE_WOLFSSL=1 \
- -DLWS_WOLFSSL_INCLUDE_DIRS=/path/to/wolfssl \
- -DLWS_WOLFSSL_LIBRARIES=/path/to/wolfssl/wolfssl.a ..
-```
-
-**NOTE**: On windows use the .lib file extension for `LWS_WOLFSSL_LIBRARIES` instead.
-
-@section cya Compiling libwebsockets with CyaSSL
-
-```
- cmake .. -DLWS_USE_CYASSL=1 \
- -DLWS_CYASSL_INCLUDE_DIRS=/path/to/cyassl \
- -DLWS_CYASSL_LIBRARIES=/path/to/wolfssl/cyassl.a ..
-```
-
-**NOTE**: On windows use the .lib file extension for `LWS_CYASSL_LIBRARIES` instead.
-
-@section esp32 Building for ESP32
-
-Step 1, get ESP-IDF with lws integrated as a component
-
-```
- $ git clone --int --recursive https://github.com/lws-team/lws-esp-idf
-```
-
-Step 2: Get Application including the test plugins
-
-```
- $ git clone https://github.com/lws-team/lws-esp32
-```
-
-Set your IDF_PATH to point to the esp-idf you downloaded in 1)
-
-There's docs for how to build the lws-esp32 test app and reproduce it in the README.md here
-
-https://github.com/lws-team/lws-esp32/blob/master/README.md
-
-
-@section extplugins Building plugins outside of lws itself
-
-The directory ./plugin-standalone/ shows how easy it is to create plugins
-outside of lws itself. First build lws itself with -DLWS_WITH_PLUGINS,
-then use the same flow to build the standalone plugin
-```
- cd ./plugin-standalone
- mkdir build
- cd build
- cmake ..
- make && sudo make install
-```
-
-if you changed the default plugin directory when you built lws, you must
-also give the same arguments to cmake here (eg,
-` -DCMAKE_INSTALL_PREFIX:PATH=/usr/something/else...` )
-
-Otherwise if you run lwsws or libwebsockets-test-server-v2.0, it will now
-find the additional plugin "libprotocol_example_standalone.so"
-```
- lwsts[21257]: Plugins:
- lwsts[21257]: libprotocol_dumb_increment.so
- lwsts[21257]: libprotocol_example_standalone.so
- lwsts[21257]: libprotocol_lws_mirror.so
- lwsts[21257]: libprotocol_lws_server_status.so
- lwsts[21257]: libprotocol_lws_status.so
-```
-If you have multiple vhosts, you must enable plugins at the vhost
-additionally, discovered plugins are not enabled automatically for security
-reasons. You do this using info->pvo or for lwsws, in the JSON config.
-
-
-@section http2rp Reproducing HTTP2.0 tests
-
-You must have built and be running lws against a version of openssl that has
-ALPN / NPN. Most distros still have older versions. You'll know it's right by
-seeing
-```
- lwsts[4752]: Compiled with OpenSSL support
- lwsts[4752]: Using SSL mode
- lwsts[4752]: HTTP2 / ALPN enabled
-```
-at lws startup.
-
-For non-SSL HTTP2.0 upgrade
-```
- $ nghttp -nvasu http://localhost:7681/test.htm
-```
-For SSL / ALPN HTTP2.0 upgrade
-```
- $ nghttp -nvas https://localhost:7681/test.html
-```
-
-@section cross Cross compiling
-
-To enable cross-compiling **libwebsockets** using CMake you need to create
-a "Toolchain file" that you supply to CMake when generating your build files.
-CMake will then use the cross compilers and build paths specified in this file
-to look for dependencies and such.
-
-**Libwebsockets** includes an example toolchain file [cross-arm-linux-gnueabihf.cmake](cross-arm-linux-gnueabihf.cmake)
-you can use as a starting point.
-
-The commandline to configure for cross with this would look like
-```
- $ cmake .. -DCMAKE_INSTALL_PREFIX:PATH=/usr \
- -DCMAKE_TOOLCHAIN_FILE=../cross-arm-linux-gnueabihf.cmake \
- -DLWS_WITHOUT_EXTENSIONS=1 -DLWS_WITH_SSL=0
-```
-The example shows how to build with no external cross lib dependencies, you
-need to provide the cross libraries otherwise.
-
-**NOTE**: start from an EMPTY build directory if you had a non-cross build in there
- before the settings will be cached and your changes ignored.
-
-Additional information on cross compilation with CMake:
- http://www.vtk.org/Wiki/CMake_Cross_Compiling
-
-@section mem Memory efficiency
-
-Embedded server-only configuration without extensions (ie, no compression
-on websocket connections), but with full v13 websocket features and http
-server, built on ARM Cortex-A9:
-
-Update at 8dac94d (2013-02-18)
-```
- $ ./configure --without-client --without-extensions --disable-debug --without-daemonize
-
- Context Creation, 1024 fd limit[2]: 16720 (includes 12 bytes per fd)
- Per-connection [3]: 72 bytes, +1328 during headers
-
- .text .rodata .data .bss
- 11512 2784 288 4
-```
-This shows the impact of the major configuration with/without options at
-13ba5bbc633ea962d46d using Ubuntu ARM on a PandaBoard ES.
-
-These are accounting for static allocations from the library elf, there are
-additional dynamic allocations via malloc. These are a bit old now but give
-the right idea for relative "expense" of features.
-
-Static allocations, ARM9
-
-| | .text | .rodata | .data | .bss |
-|--------------------------------|---------|---------|-------|------|
-| All (no without) | 35024 | 9940 | 336 | 4104 |
-| without client | 25684 | 7144 | 336 | 4104 |
-| without client, exts | 21652 | 6288 | 288 | 4104 |
-| without client, exts, debug[1] | 19756 | 3768 | 288 | 4104 |
-| without server | 30304 | 8160 | 336 | 4104 |
-| without server, exts | 25382 | 7204 | 288 | 4104 |
-| without server, exts, debug[1] | 23712 | 4256 | 288 | 4104 |
-
-[1] `--disable-debug` only removes messages below `lwsl_notice`. Since that is
-the default logging level the impact is not noticeable, error, warn and notice
-logs are all still there.
-
-[2] `1024` fd per process is the default limit (set by ulimit) in at least Fedora
-and Ubuntu. You can make significant savings tailoring this to actual expected
-peak fds, ie, at a limit of `20`, context creation allocation reduces to `4432 +
-240 = 4672`)
-
-[3] known header content is freed after connection establishment

-ESP8266 lws port
-----------------
-
-lws can now work well on the ESP8266.
-
-You should get the ESP8266 Espressif SDK-based project here
-
-https://github.com/lws-team/esplws
-
-which includes lws as an "app" in the build. The project provides full AP-based setup over the web, and once the device has been configured to associate to a local AP, a separate station vhost with the lws test protocols.
-
-Instructions for building that are here
-
-https://github.com/lws-team/esplws/blob/master/README.md
-
-There are also instructions there for how to remove the test apps from the build and customize your own station content.
-
-
-Information about lws integration on ESP8266
---------------------------------------------
-
-The following existing lws features are used to make a nice integration:
-
- - vhosts: there are separate vhosts for the configuration AP mode and the normal station mode.
-
- - file_ops: the lws file operations are overridden and handled by a ROMFS parser
-
- - mounts: mounts are used to serve files automatically from the ROMFS
-
- - plugins: standalone protocol plugins are included into the build, so there are clean individual implementations for each protocol, while everything is statically linked
-
- - lws stability and security features like bytewise parsers, sophisticated timeouts, http/1.1 keepalive support
-

-# lws-meta protocol
-
-lws-meta is a lightweight ws subprotocol that accepts other ws connections
-to the same server inside it and multiplexes their access to the connection.
-
-```
- Client Server
-
- conn1: \ / :conn1
- conn2: = mux ------ lws-meta ws protocol ----- mux = :conn2
- conn3: / \ :conn3
-```
-
-You may have n client ws connections back to the server, but you now
-only have one tcp connection (and one SSL wrapper if using SSL) instead
-of n of those.
-
-If you currently make multiple ws connections back to the server, so you
-can have different protocols active in one webpage, this if for you.
-
- - The subprotocol code for the connections inside a lws-meta connection
- need zero changes from being a normal ws connection. It is unaware
- it is inside an lws-meta parent connection.
-
- - The traffic on the lws-meta connection is indistinguishable from
- standard ws traffic, so intermediaries won't object to it
-
- - The multiplexing is done in the protocol, **not by an extension**. So
- it's compatible with all browsers.
-
- - Javascript helper code is provided to very simply use lws-meta
- protocol instead of direct connections. The lws test server has
- been converted to use this by default.
-
-# Converting your server
-
-1) include the provided lws-meta plugin (plugins/protocl_lws_meta.c) as an
-active protocol for your server. You can do that using runtime plugins, or
-include the plugin sources into your server at build-time. The lws test
-server uses the latter approach.
-
-That's all you need to do on the server side.
-
-# Converting your browser JS
-
-1) import lws-common.js
-
-2) Instantiate a parent lws-meta connection object
-
-```
-var lws_meta = new lws_meta_ws();
-```
-
-3) Connect the lws-meta object to your server
-
-```
-lws_meta.new_parent(get_appropriate_ws_url("?mirror=" + mirror_name));
-```
-
-4) Convert your actual ws connections to go via the lws_meta object
-
-```
-var my_ws = lws_meta.new_ws("", "dumb-increment-protocol");
-```
-
-The first arg is the URL path, the second arg is the ws protocol you want.
-
-That's it. my_ws will get `onopen()`, `onmessage()` etc calls as before.
-
-# lws-meta wire protocol
-
-lws-meta works by adding some bytes at the start of a message indicating
-which channel the message applies to.
-
-Channel messages are atomic on the wire. The reason is if we tried to
-intersperse other channel fragments between one channels message fragments,
-an intermediary would observe violations of the ws framing rule about
-having to start a message with TEXT or BINARY, and use only CONTINUATION
-for the subsequent fragments. Eg

-
-is illegal to an observer that doesn't understand lws-meta headers in the
-packet payloads. So to avoid this situation, only complete messages may
-be sent from one subchannel in each direction at a time.
-
-Consequently, only the first fragment of each message is modified to
-have the extra two bytes identifying the subchannel it is aimed at, since
-the rest of the message from the same subchannel is defined to follow.
-
-If it makes latencies, modify the protocol sending large messages to
-send smaller messages, so the transmission of messages from other channels
-can be sent inbetween the smaller messages.
-
-## lws-meta commands
-
-1) CSTRING indicates a string terminated by 0x00 byte
-
-2) Channel IDs are sent with 0x20 added to them, to guarantee valid UTF-8
-
-### 0x41: RX: LWS_META_CMD_OPEN_SUBCHANNEL
-
- - CSTRING: protocol name
- - CSTRING: url
- - CSTRING: cookie (7 bytes max)
-
-Client is requesting to open a new channel with the given protocol name,
-at the given url. The cookie (eg, channel name) is only used in
-LWS_META_CMD_OPEN_RESULT, when the channel id is assigned, so it is
-applied to the right channel.
-
-### 0x42: TX: LWS_META_CMD_OPEN_RESULT
-
- - CSTRING cookie
- - BYTE channel id (0 indicates failed)
- - CSTRING: selected protocol name
-
-The server is informing the client of the results of a previous
-open request. The cookie the client sent to identify the request
-is returned along with a channel id to be used subsequently. If
-the channel ID is 0 (after subtracting the transport offset of
-0x20) then the open request has failed.
-
-### 0x43: TX: LWS_META_CMD_CLOSE_NOTIFY
-
- - BYTE channel id
- - BYTE: payload length + 0x20
- - BYTE: close code MSB
- - BYTE: close code LSB
- - PAYLOAD: payload (< 123 bytes)
-
-Server notifies the client that a child has closed, for whatever reason.
-
-### 0x44: RX: LWS_META_CMD_CLOSE_RQ
- - BYTE: channel id
- - BYTE: payload length + 0x20
- - BYTE: close code MSB
- - BYTE: close code LSB
- - PAYLOAD: payload (< 123 bytes)
-
-The client requests to close a child connection
-
-### 0x45: TX: LWS_META_CMD_WRITE
-
- - BYTE: channel id
-
-Normal write of payload n from lws-meta perspective is actually
-LWS_META_CMD_WRITE, channel id, then (n - 2) bytes of payload
-
-The command only appears at the start of a message, continuations do
-not have the command.
-
-## Protocol Notes
-
- - Once the subchannel is up, overhead is only +2 bytes per message
-
- - Close reasons are supported in both directions
-
- - Ping and Pong are only supported at the lws-meta level, using normal ws ping and pong packets.
-
- - Only the final close of the tcp lws-meta connection itself goes out as
- a normal ws close frame. Subchannels close is done in a normal TEXT
- message using LWS_META_CMD_CLOSE_RQ and then the close packet payload.
- This is so intermediaries do not mistake subchannel closures for the
- tcp / ws link going down.
-
- Messages that start with LWS_META_CMD_OPEN_SUBCHANNEL only contain those
- commands but may contain any number of them for the whole duration of the
- message. The lws-meta js support collects child open requests made before
- the parent lws-meta connection is open, and dumps them all in a single
- message when it does open.
-
- Messages that start with LWS_META_CMD_OPEN_RESULT or LWS_META_CMD_CLOSE_NOTIFY
- only contain those two commands, but they may contain any number of them
- for the whole duration of the message.
-
-
-# Current Implemention Limitations
-
- - only server side is supported in lws. The client side JS for
- a browser is supported.
-
- - max number of child connections per parent at the moment is 8
-
- - child connection URL paramter when opening the connection is
- ignored
-
- - there is no ah attached when the child connections are
- established inside the lws-meta parent. So header access
- functions will fail.

+# Libwebsockets
+
+Libwebsockets is a simple-to-use, pure C library providing client and server
+for **http/1**, **http/2**, **websockets** and other protocols in a security-minded,
+lightweight, configurable, scalable and flexible way. It's easy to build and
+cross-build via cmake and is suitable for tasks from embedded RTOS through mass
+cloud serving.
+
+[50 minimal examples](https://libwebsockets.org/git/libwebsockets/tree/minimal-examples) for
+various scenarios, CC0-licensed (public domain) for cut-and-paste, allow you to get started quickly.

News
----
-v2.3 is out... see the changelog https://github.com/warmcat/libwebsockets/blob/v2.3-stable/changelog
+## V3.2 relase last planned LGPLv2.1+SLE release
+
+As foretold the v3.2 release is the last planned release that will have the code
+under LGPLv2.1+SLE. Master has those parts changed to MIT license; the pieces
+that were CC0 or another liberal license remain the same.
+
+## License change plan
+
+Lws is planning to change the pieces that are currently LGPLv2.1+SLE to MIT
+https://opensource.org/licenses/MIT . Stuff that is already CC0 or another
+permissive license will stay as it is.
+
+This license change is making an already permissive license (it was already LGPL,
+and the SLE removed most restrictions already) even more permissive.
+So I expect most contributors either don't much care or are happy about it.
+Contributors who object should contact me via:
+
+ - the lws mailing list https://libwebsockets.org/mailman/listinfo/libwebsockets
+ - github issue https://github.com/warmcat/libwebsockets , or
+ - email to `andy@warmcat.com`
+
+...before **Aug 11 2019**, and I'll rewrite the related code before the change.
+There'll be a last release of the currently-licensed stuff (probably v3.2) and
+then the same code will have the licese grant changed in the sources, become
+master and also have an otherwise identical release, probably v4.0. The v3.2
+stuff won't be maintained (by me anyway... it's FOSS though) but the v4.0
+stuff which is the same except the license will get the usual v4.0-stable
+treatment.
+
+Even after the change I will continue to rely on users to help me with bug
+reports and patches, work together on new features. The license will no
+longer require it but the practical advantages from staying aligned with
+upstream lws for users remain the same.
+
+## New features on master
+
+ - `LWS_WITH_NETWORK` cmake option (default on) allows one-step removal of vhost,
+ wsi, roles, event loop and all network-related code from the build. This
+ enables use-cases where you actually need unrelated features like JOSE or FTS
+ compactly. lws_context still exists and if tls is enabled, the tls-related code
+ is still built so the crypto is available, just nothing related to network.
+
+ - New Crypto-agile APIs + JOSE / JWS / JWE / JWK support... apis work exactly
+ the same with OpenSSL or mbedTLS tls library backends, and allow key cycling
+ and crypto algorithm changes while allowing for grace periods
+
+ [README.crypto-apis](https://libwebsockets.org/git/libwebsockets/tree/READMEs/README.crypto-apis.md)
+
+ - CMake config simplification for crypto: `-DLWS_WITH_GENCRYPTO=1` for all
+ generic cipher and hash apis built (which work the same on mbedtls and
+ OpenSSL transparently), and `-DLWS_WITH_JOSE=1` for all JOSE, JWK, JWS
+ and JWE support built (which use gencrypto and so also work the same
+ regardless of tls library backend).
+
+ - **`x.509`** - new generic x509 api allows PEM-based certificate and key
+ trust relationship verification, and conversion between x.509 keys and
+ JWK. Works for EC and RSA keys, and on mbedtls and OpenSSl the same.
+
+ [x.509 api](https://libwebsockets.org/git/libwebsockets/tree/include/libwebsockets/lws-x509.h),
+ [x.509 minimal example](https://libwebsockets.org/git/libwebsockets/tree/minimal-examples/crypto/minimal-crypto-x509)
+
+ - **`JWE`** - JWE (RFC7516) Algorithms with CI tests:
+
+|Key Encryption|Payload authentication + crypt|Enc + Dec Support|
+|---|---|---|
+|`RSAES-PKCS1-v1.5` 2048b & 4096b|`AES_128_CBC_HMAC_SHA_256`|Enc + Dec|
+|`RSAES-PKCS1-v1.5` 2048b|`AES_192_CBC_HMAC_SHA_384`|Enc + Dec|
+|`RSAES-PKCS1-v1.5` 2048b|`AES_256_CBC_HMAC_SHA_512`|Enc + Dec|
+|`RSAES-OAEP`|`AES_256_GCM`|Enc + Dec|
+|`AES128KW`, `AES192KW`, `AES256KW`|`AES_128_CBC_HMAC_SHA_256`|Enc + Dec|
+|`AES128KW`, `AES192KW`, `AES256KW`|`AES_192_CBC_HMAC_SHA_384`|Enc + Dec|
+|`AES128KW`, `AES192KW`, `AES256KW`|`AES_256_CBC_HMAC_SHA_512`|Enc + Dec|
+|`ECDH-ES` (P-256/384/521 key)|`AES_128/192/256_GCM`|Enc + Dec|
+|`ECDH-ES+A128/192/256KW` (P-256/384/521 key)|`AES_128/192/256_GCM`|Enc + Dec|
+
+All tests pass on both OpenSSL and mbedTLS backends, using keys generated on
+both OpenSSL and mbedTLS in the tests.
+
+A minimal example tool shows how to encrypt and decrypt compact JWE objects
+from the commandline for all supported algorithms.

+
+ - **`lws-genec` ECDSA** - JWS-compatible ECDSA is supported on both OpenSSL and mbedtls.
+
+ - **`JWS`** - JWS (RFC7515) is now supported for none, HS256/384/512, RS256/384/512, and ES256/384/512, on both OpenSSL and mbedtls. There's a minimal example tool that signs and verifies compact

+
+ - **`JWK`** - JWK (RFC7517) now supports oct, RSA and EC keys including JSON key
+ arrays on both OpenSSL and mbedtls. A minimal example tool shows how to create
+ new JSON JWK keys to specified parameters from the commandline for all supported
+ ciphers.
+
+ [jwk minimal example](https://libwebsockets.org/git/libwebsockets/tree/minimal-examples/crypto/minimal-crypto-jwk)
+
+ - **`lws-genrsa` OAEP + PSS support** - in addition to PKCS#1 1.5 padding, OAEP and PSS are
+ now supported on both mbedtls and openssl backends.
+
+ - **`lws-genaes` Generic AES crypto** - thin api layer works identically with both mbedtls and openssl
+ backends. Supports CBC, CFB128, CFB8, CTR, ECB, OFB, XTS and GCM variants. Unit tests in CI.

+ CMake config: `-DLWS_WITH_GENCRYPTO=1`
+
+ - **http fallback support** - you can specify a role and protocol to apply if non-http or non-tls
+ packets arrive at an http(s) listen port. For example, you can specify that the new `raw proxy`
+ role + protocol should be used, to proxy your sshd port over :443 or :80. Without affecting
+ normal http(s) serving on those ports but allowing, eg, `ssh -p 443 invalid@libwebsockets.org`.
+ [http fallback docs](https://libwebsockets.org/git/libwebsockets/tree/READMEs/README.http-fallback.md)
+
+ - **raw tcp proxy role and protocol** - adding raw tcp proxying is now trivial using the built-in lws
+ implementation. You can control the onward connection using a pvo in the format "ipv4:server.com:port"
+ [raw proxy minimal example](https://libwebsockets.org/git/libwebsockets/tree/minimal-examples/raw/minimal-raw-proxy),
+ [raw proxy docs](https://libwebsockets.org/git/libwebsockets/tree/plugins/raw-proxy),
+ Cmake config: `-DLWS_ROLE_RAW_PROXY=1 -DLWS_WITH_PLUGINS=1`
+
+ - **deaddrop HTML file upload protocol** - protocol and minimal example for file upload and sharing using
+ drag and drop and a file picker. Integrated with basic auth, uploaded files marked with upload user,
+ and files owned by the authenticated user may be deleted via the UI. Supports multiple simultaneous
+ uploads both by drag-and-drop and from the file picker.
+ [deaddrop minimal example](https://libwebsockets.org/git/libwebsockets/tree/minimal-examples/http-server/minimal-http-server-deaddrop)
+
+ - **basic auth for ws(s)** - You can apply basic auth credential requirement to ws connections same
+ as on mounts now. Just add a pvo "basic-auth" with the value being the credentials file path when
+ enabling the ws protocol for the vhost.

+
+The over 1,500 tests run on every commit take 1hr 15 of compute time to complete.
+If any problems are found, it breaks the travis build, generating an email.
+
+Codacy also checks every patch and the information used to keep lws at zero issues.
+
+Current master is checked by Coverity at least daily and kept at zero issues.
+
+Current master passes all the tests and these new CI arrangements will help
+keep it that way.
+
+## Lws has the first official ws-over-h2 server support
+
+
+
+There's a new [RFC](https://tools.ietf.org/html/rfc8441) that enables multiplexing ws connections
+over an http/2 link. Compared to making individual tcp and tls connections for
+each ws link back to the same server, this makes your site start up radically
+faster, and since all the connections are in one tls tunnel, with considerable memory
+reduction serverside.
+
+To enable it on master you just need -DLWS_WITH_HTTP2=1 at cmake. No changes to
+existing code are necessary for either http/2 (if you use the official header creation
+apis if you return your own headers, as shown in the test apps for several versions)
+or to take advantage of ws-over-h2. When built with http/2 support, it automatically
+falls back to http/1 and traditional ws upgrade if that's all the client can handle.
+
+Currently only Chrome Canary v67 supports this ws-over-h2 encapsulation (chrome
+must be started with `--enable-websocket-over-http2` switch to enable it currently),
+and patches exist for Firefox. Authors of both browser implementations tested
+against the lws server implementation.
+
+## New "minimal examples"
+
+https://libwebsockets.org/git/libwebsockets/tree/minimal-examples
+
+These are like the test apps, but focus on doing one thing, the best way, with the
+minimum amount of code. For example the minimal-http-server serves the cwd on
+http/1 or http/2 in 50 LOC. Same thing with tls is just three more lines.
+
+They build standalone, so it's easier to copy them directly to start your own project; they
+are CC0 licensed (public domain) to facilitate that.
+
+## Windows binary builds

+32- and 64-bit Windows binary builds are available via Appveyor. Visit
+[lws on Appveyor](https://ci.appveyor.com/project/lws-team/libwebsockets),

-Debugging problems
-==================
-
-Library is a component
-----------------------
-
-As a library, lws is always just a component in a bigger application.
-
-When users have a problem involving lws, what is happening in the bigger
-application is usually critical to understand what is going on (and where the
-solution lies).
-
-Many users are able to share their sources, but others decide not to, for
-presumed "commercial advantage" or whatever. (In any event, it can be painful
-looking through large chunks of someone else's sources for problems when that
-is not the library author's responsibility.)
-
-This makes answering questions like "what is wrong with my code I am not
-going to show you?" or even "what is wrong with my code?" very difficult.
-
-Even if it's clear there is a problem somewhere, it cannot be understood or
-reproduced by anyone else if it needs user code that isn't provided.
-
-The biggest question is, "is this an lws problem actually"?
-
-
-Use the test apps as sanity checks
-----------------------------------
-
-The test server and client are extremely useful for sanity checks and debugging
-guidance.
-
- - test apps work on your platform, then either
- - your user code is broken, align it to how the test apps work, or,
- - something from your code is required to show an lws problem, provide a
- minimal patch on a test app so it can be reproduced
-
- - test apps break on your platform, but work on, eg, x86_64, either
- - toolchain or platform-specific (eg, OS) issue, or
- - lws platform support issue
-
- - test apps break everywhere
- - sounds like lws problem, info to reproduce and / or a patch is appreciated

+Notes about building lws
+========================
+
+
+@section cm Introduction to CMake
+
+CMake is a multi-platform build tool that can generate build files for many
+different target platforms. See more info at http://www.cmake.org
+
+CMake also allows/recommends you to do "out of source"-builds, that is,
+the build files are separated from your sources, so there is no need to
+create elaborate clean scripts to get a clean source tree, instead you
+simply remove your build directory.
+
+Libwebsockets has been tested to build successfully on the following platforms
+with SSL support (for OpenSSL/wolfSSL/BoringSSL):
+
+- Windows (Visual Studio)
+- Windows (MinGW)
+- Linux (x86 and ARM)
+- OSX
+- NetBSD
+
+
+@section build1 Building the library and test apps
+
+The project settings used by CMake to generate the platform specific build
+files is called [CMakeLists.txt](../CMakeLists.txt). CMake then uses one of its "Generators" to
+output a Visual Studio project or Make file for instance. To see a list of
+the available generators for your platform, simply run the "cmake" command.
+
+Note that by default OpenSSL will be linked, if you don't want SSL support
+see below on how to toggle compile options.
+
+
+@section bu Building on Unix:
+
+1. Install CMake 2.8 or greater: http://cmake.org/cmake/resources/software.html
+ (Most Unix distributions comes with a packaged version also)
+
+2. Install OpenSSL.
+
+3. Generate the build files (default is Make files):
+```
+ $ cd /path/to/src
+ $ mkdir build
+ $ cd build
+ $ cmake ..
+```
+
+4. Finally you can build using the generated Makefile:
+```
+ $ make && sudo make install
+```
+**NOTE**: The `build/`` directory can have any name and be located anywhere
+ on your filesystem, and that the argument `..` given to cmake is simply
+ the source directory of **libwebsockets** containing the [CMakeLists.txt](../CMakeLists.txt)
+ project file. All examples in this file assumes you use ".."
+
+**NOTE2**:
+A common option you may want to give is to set the install path, same
+as --prefix= with autotools. It defaults to /usr/local.
+You can do this by, eg
+```
+ $ cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr .
+```
+
+**NOTE3**:
+On machines that want libraries in lib64, you can also add the
+following to the cmake line
+```
+ -DLIB_SUFFIX=64
+```
+
+**NOTE4**:
+If you are building against a non-distro OpenSSL (eg, in order to get
+access to ALPN support only in newer OpenSSL versions) the nice way to
+express that in one cmake command is eg,
+```
+ $ cmake .. -DOPENSSL_ROOT_DIR=/usr/local/ssl \
+ -DCMAKE_INCLUDE_DIRECTORIES_PROJECT_BEFORE=/usr/local/ssl \
+ -DLWS_WITH_HTTP2=1
+```
+
+When you run the test apps using non-distro SSL, you have to force them
+to use your libs, not the distro ones
+```
+ $ LD_LIBRARY_PATH=/usr/local/ssl/lib libwebsockets-test-server --ssl
+```
+
+To get it to build on latest openssl (2016-04-10) it needed this approach
+```
+ cmake .. -DLWS_WITH_HTTP2=1 -DLWS_OPENSSL_INCLUDE_DIRS=/usr/local/include/openssl -DLWS_OPENSSL_LIBRARIES="/usr/local/lib64/libssl.so;/usr/local/lib64/libcrypto.so"
+```
+
+Mac users have reported
+
+```
+ $ export OPENSSL_ROOT_DIR=/usr/local/Cellar/openssl/1.0.2k; cmake ..; make -j4
+```
+
+worked for them when using "homebrew" OpenSSL
+
+**NOTE5**:
+To build with debug info and _DEBUG for lower priority debug messages
+compiled in, use
+```
+ $ cmake .. -DCMAKE_BUILD_TYPE=DEBUG
+```
+
+**NOTE6**
+To build on Solaris the linker needs to be informed to use lib socket
+and libnsl, and only builds in 64bit mode.
+
+```bash
+ $ cmake .. -DCMAKE_C_FLAGS=-m64 -DCMAKE_EXE_LINKER_FLAGS="-lsocket -lnsl"
+```
+
+**NOTE7**
+
+Build and test flow against boringssl. Notice `LWS_WITH_GENHASH` is currently
+unavailable with boringssl due to their removing the necessary apis.
+
+Build current HEAD boringssl
+
+```
+ $ cd /projects
+ $ git clone https://boringssl.googlesource.com/boringssl
+ $ cd boringssl
+ $ mkdir build
+ $ cd build
+ $ cmake .. -DBUILD_SHARED_LIBS=1
+ $ make -j8
+```
+
+Build and test lws against it
+
+```
+ $ cd /projects/libwebsockets/build
+ $ cmake .. -DOPENSSL_LIBRARIES="/projects/boringssl/build/ssl/libssl.so;\
+ /projects/boringssl/build/crypto/libcrypto.so" \
+ -DOPENSSL_INCLUDE_DIRS=/projects/boringssl/include \
+ -DLWS_WITH_BORINGSSL=1 -DCMAKE_BUILD_TYPE=DEBUG
+ $ make -j8 && sudo make install
+ $ LD_PRELOAD="/projects/boringssl/build/ssl/libssl.so \
+ /projects/boringssl/build/crypto/libcrypto.so" \
+ /usr/local/bin/libwebsockets-test-server -s
+```
+
+4. Finally you can build using the generated Makefile:
+
+```bash
+ $ make
+ ```
+
+@section lcap Linux Capabilities
+
+On Linux, lws now lets you retain selected root capabilities when dropping
+privileges. If libcap-dev or similar package is installed providing
+sys/capabilities.h, and libcap or similar package is installed providing
+libcap.so, CMake will enable the capability features.
+
+The context creation info struct .caps[] and .count_caps members can then
+be set by user code to enable selected root capabilities to survive the
+transition to running under an unprivileged user.
+
+@section cmq Quirk of cmake
+
+When changing cmake options, for some reason the only way to get it to see the
+changes sometimes is delete the contents of your build directory and do the
+cmake from scratch.
+
+deleting build/CMakeCache.txt may be enough.
+
+
+@section cmw Building on Windows (Visual Studio)
+
+1. Install CMake 2.6 or greater: http://cmake.org/cmake/resources/software.html
+
+2. Install OpenSSL binaries. https://wiki.openssl.org/index.php/Binaries
+
+ (**NOTE**: Preferably in the default location to make it easier for CMake to find them)
+
+ **NOTE2**:
+ Be sure that OPENSSL_CONF environment variable is defined and points at
+ <OpenSSL install location>\bin\openssl.cfg
+
+3. Generate the Visual studio project by opening the Visual Studio cmd prompt:
+
+```
+ cd <path to src>
+ md build
+ cd build
+ cmake -G "Visual Studio 10" ..
+```
+
+ (**NOTE**: There is also a cmake-gui available on Windows if you prefer that)
+
+ **NOTE2**:
+ See this link to find out the version number corresponding to your Visual Studio edition:
+ http://superuser.com/a/194065
+
+4. Now you should have a generated Visual Studio Solution in your
+ `<path to src>/build` directory, which can be used to build.
+
+5. Some additional deps may be needed
+
+ - iphlpapi.lib
+ - psapi.lib
+ - userenv.lib
+
+6. If you're using libuv, you must make sure to compile libuv with the same multithread-dll / Mtd attributes as libwebsockets itself
+
+
+@section cmwmgw Building on Windows (MinGW)
+
+1. Install MinGW
+
+ For Fedora, it's, eg, `dnf install mingw64-gcc`
+
+2. Install current CMake package
+
+ For Fedora, it's `dnf install cmake`
+
+3. Instal mingw-built OpenSSL pieces
+
+ For Fedora, it's `mingw64-openssl.noarch mingw64-openssl-static.noarch`
+
+ mingw64-cmake as described below will auto-find the libs and includes
+ for build. But to execute the apps, they either need to go into the same
+ `/usr/x86_64-w64-mingw32/sys-root/mingw/bin/` as the dlls are installed to,
+ or the dlls have to be copied into the same dir as your app executable.
+
+4. Generate the build files (default is Make files) using MSYS shell.
+
+ For Fedora, they provide a `mingw64-cmake` wrapper in the package
+ `mingw64-filesystem`, with this you can run that instead of cmake directly
+ and don't have to get involved with setting the cmake generator.
+
+ Otherwise doing it by hand is like this:
+
+```
+ $ cd /drive/path/to/src
+ $ mkdir build
+ $ cd build
+ $ cmake -G "MSYS Makefiles" -DCMAKE_INSTALL_PREFIX=C:/MinGW ..
+```
+
+ To generate build files allowing to create libwebsockets binaries with debug information
+ set the CMAKE_BUILD_TYPE flag to DEBUG:
+```
+ $ cmake -G "MSYS Makefiles" -DCMAKE_INSTALL_PREFIX=C:/MinGW -DCMAKE_BUILD_TYPE=DEBUG ..
+```
+5. Finally you can build using the generated Makefile and get the results deployed into your MinGW installation:
+
+```
+ $ make && make install
+```
+
+@section distro Selecting CMake options useful for distros
+
+Distro packagers should select the CMake option "LWS_WITH_DISTRO_RECOMMENDED",
+which selects common additional options like support for various event libraries,
+plugins and lwsws.
+
+@section ssllib Choosing Your TLS Poison
+
+ - If you are really restricted on memory, code size, or don't care about TLS
+ speed, mbedTLS is a good choice: `cmake .. -DLWS_WITH_MBEDTLS=1`
+
+ - If cpu and memory is not super restricted and you care about TLS speed,
+ OpenSSL or a directly compatible variant like Boring SSL is a good choice.
+
+Just building lws against stock Fedora OpenSSL or stock Fedora mbedTLS, for
+SSL handhake mbedTLS takes ~36ms and OpenSSL takes ~1ms on the same x86_64
+build machine here, with everything else the same. Over the 144 connections of
+h2spec compliance testing for example, this ends up completing in 400ms for
+OpenSSL and 5.5sec for mbedTLS on x86_64. In other words mbedTLS is very slow
+compared to OpenSSL under the (fairly typical) conditions I tested it.
+
+This isn't an inefficiency in the mbedtls interface implementation, it's just
+mbedTLS doing the crypto much slower than OpenSSL, which has accelerated
+versions of common crypto operations it automatically uses for platforms
+supporting it. As of Oct 2017 mbedTLS itself has no such optimizations for any
+platform that I could find. It's just pure C running on the CPU.
+
+Lws supports both almost the same, so instead of taking my word for it you are
+invited to try it both ways and see which the results (including, eg, binary
+size and memory usage as well as speed) suggest you use.
+
+NOTE: one major difference with mbedTLS is it does not load the system trust
+store by default. That has advantages and disadvantages, but the disadvantage
+is you must provide the CA cert to lws built against mbedTLS for it to be able
+to validate it, ie, use -A with the test client. The minimal test clients
+have the CA cert for warmcat.com and libwebsockets.org and use it if they see
+they were built with mbedTLS.
+
+@section optee Building for OP-TEE
+
+OP-TEE is a "Secure World" Trusted Execution Environment.
+
+Although lws is only part of the necessary picture to have an https-enabled
+TA, it does support OP-TEE as a platform and if you provide the other
+pieces, does work very well.
+
+Select it in cmake with `-DLWS_PLAT_OPTEE=1`
+
+
+@section cmco Setting compile options
+
+To set compile time flags you can either use one of the CMake gui applications
+or do it via the command line.
+
+@subsection cmcocl Command line
+
+To list available options (omit the H if you don't want the help text):
+
+ cmake -LH ..
+
+Then to set an option and build (for example turn off SSL support):
+
+ cmake -DLWS_WITH_SSL=0 ..
+or
+ cmake -DLWS_WITH_SSL:BOOL=OFF ..
+
+@subsection cmcoug Unix GUI
+
+If you have a curses-enabled build you simply type:
+(not all packages include this, my debian install does not for example).
+
+ ccmake
+
+@subsection cmcowg Windows GUI
+
+On windows CMake comes with a gui application:
+ Start -> Programs -> CMake -> CMake (cmake-gui)
+
+
+@section wolf wolfSSL/CyaSSL replacement for OpenSSL
+
+wolfSSL/CyaSSL is a lightweight SSL library targeted at embedded systems:
+https://www.wolfssl.com/wolfSSL/Products-wolfssl.html
+
+It contains a OpenSSL compatibility layer which makes it possible to pretty
+much link to it instead of OpenSSL, giving a much smaller footprint.
+
+**NOTE**: wolfssl needs to be compiled using the `--enable-opensslextra` flag for
+this to work.
+
+@section wolf1 Compiling libwebsockets with wolfSSL
+
+```
+ cmake .. -DLWS_WITH_WOLFSSL=1 \
+ -DLWS_WOLFSSL_INCLUDE_DIRS=/path/to/wolfssl \
+ -DLWS_WOLFSSL_LIBRARIES=/path/to/wolfssl/wolfssl.a ..
+```
+
+**NOTE**: On windows use the .lib file extension for `LWS_WOLFSSL_LIBRARIES` instead.
+
+@section cya Compiling libwebsockets with CyaSSL
+
+```
+ cmake .. -DLWS_WITH_CYASSL=1 \
+ -DLWS_CYASSL_INCLUDE_DIRS=/path/to/cyassl \
+ -DLWS_CYASSL_LIBRARIES=/path/to/wolfssl/cyassl.a ..
+```
+
+**NOTE**: On windows use the .lib file extension for `LWS_CYASSL_LIBRARIES` instead.
+
+@section gzip Selecting GZIP or MINIZ
+
+By default lws supports gzip when compression is needed. But you can tell it to use
+MINIZ instead by using `-DLWS_WITH_MINIZ=1`.
+
+For native build cmake will try to find an existing libminiz.so or .a and build
+against that and the found includes automatically.
+
+For cross-build or building against local miniz, you need the following kind of
+cmake to tell it where to get miniz
+
+```
+cmake .. -DLWS_WITH_MINIZ=1 -DLWS_WITH_ZIP_FOPS=1 -DMINIZ_INCLUDE_DIRS="/projects/miniz;/projects/miniz/build" -DMINIZ_LIBRARIES=/projects/miniz/build/libminiz.so.2.1.0
+```
+
+@section esp32 Building for ESP32
+
+Building for ESP32 requires the ESP-IDF framework. It can be built under Linux, OSX or Windows (MSYS2).
+
+1. Install ESP-IDF, follow the getting started guide here - http://esp-idf.readthedocs.io/en/latest/get-started/
+2. Set ESP-IDF to last known working version (assuming ESP-IDF is in `~/esp/esp-idf`) :
+```
+ cd ~/esp/esp-idf
+ git checkout 0c50b65a34cd6b3954f7435193411a88adb49cb0
+ git submodule update --recursive
+```
+3. Add `libwebsockets` as a submodule in the `components` folder of your ESP-IDF project:
+```
+ git submodule add https://github.com/warmcat/libwebsockets.git components/libwebsockets
+```
+4. If on Windows (MSYS2) you will need to install CMake in the MSYS2 environment:
+```
+ pacman -S mingw-w64-i686-cmake
+```
+If you're on Linux or OSX ensure CMake version is at least 3.7.
+
+@section extplugins Building plugins outside of lws itself
+
+The directory ./plugin-standalone/ shows how easy it is to create plugins
+outside of lws itself. First build lws itself with -DLWS_WITH_PLUGINS,
+then use the same flow to build the standalone plugin
+```
+ cd ./plugin-standalone
+ mkdir build
+ cd build
+ cmake ..
+ make && sudo make install
+```
+
+if you changed the default plugin directory when you built lws, you must
+also give the same arguments to cmake here (eg,
+` -DCMAKE_INSTALL_PREFIX:PATH=/usr/something/else...` )
+
+Otherwise if you run lwsws or libwebsockets-test-server-v2.0, it will now
+find the additional plugin "libprotocol_example_standalone.so"
+```
+ lwsts[21257]: Plugins:
+ lwsts[21257]: libprotocol_dumb_increment.so
+ lwsts[21257]: libprotocol_example_standalone.so
+ lwsts[21257]: libprotocol_lws_mirror.so
+ lwsts[21257]: libprotocol_lws_server_status.so
+ lwsts[21257]: libprotocol_lws_status.so
+```
+If you have multiple vhosts, you must enable plugins at the vhost
+additionally, discovered plugins are not enabled automatically for security
+reasons. You do this using info->pvo or for lwsws, in the JSON config.
+
+
+@section http2rp Reproducing HTTP/2 tests
+
+Enable `-DLWS_WITH_HTTP2=1` in cmake to build with http/2 support enabled.
+
+You must have built and be running lws against a version of openssl that has
+ALPN. At the time of writing, recent distros have started upgrading to OpenSSL
+1.1+ that supports this already. You'll know it's right by seeing
+
+```
+ lwsts[4752]: Compiled with OpenSSL support
+ lwsts[4752]: Using SSL mode
+ lwsts[4752]: HTTP2 / ALPN enabled
+```
+at lws startup.
+
+Recent Firefox and Chrome also support HTTP/2 by ALPN, so these should just work
+with the test server running in -s / ssl mode.
+
+For testing with nghttp client:
+
+```
+ $ nghttp -nvas https://localhost:7681/test.html
+```
+
+Testing with h2spec (https://github.com/summerwind/h2spec)
+
+```
+ $ h2spec -h 127.0.0.1 -p 7681 -t -k -v -o 1
+```
+
+```
+145 tests, 145 passed, 0 skipped, 0 failed
+
+```
+
+@section coverage Automated Coverage Testing
+
+./test-apps/attack.sh contains scripted tests that are the basis
+of the automated test coverage assessment available for gcc and clang.
+
+To reproduce
+
+ $ cd build
+ $ cmake .. -DLWS_WITH_GCOV=1 -DCMAKE_BUILD_TYPE=DEBUG
+ $ ../scripts/build-gcov.sh
+ $ ../test-apps/attack.sh
+ $ ../scripts/gcov.sh
+...
+Lines executed:51.24% of 8279
+
+@section windowsprebuilt Using Windows binary builds on Appveyor
+
+The CI builds on Appveyor now produce usable binary outputs. Visit
+
+[lws on Appveyor](https://ci.appveyor.com/project/lws-team/libwebsockets)
+
+and select one of the builds, then click on ARTIFACTS at the top right. The zip file
+want to be unpacked into `C:\Program Files (x86)/libwebsockets`, after that, you should be able to run the test server, by running it from `bin/Release/libwebsockets-test-server.exe` and opening a browser on http://127.0.0.1:7681
+
+@section cross Cross compiling
+
+To enable cross-compiling **libwebsockets** using CMake you need to create
+a "Toolchain file" that you supply to CMake when generating your build files.
+CMake will then use the cross compilers and build paths specified in this file
+to look for dependencies and such.
+
+**Libwebsockets** includes an example toolchain file [cross-arm-linux-gnueabihf.cmake](../contrib/cross-arm-linux-gnueabihf.cmake)
+you can use as a starting point.
+
+The commandline to configure for cross with this would look like
+```
+ $ cmake .. -DCMAKE_INSTALL_PREFIX:PATH=/usr/lib/my-cross-root \
+ -DCMAKE_TOOLCHAIN_FILE=../contrib/cross-arm-linux-gnueabihf.cmake \
+ -DLWS_WITHOUT_EXTENSIONS=1 -DLWS_WITH_SSL=0 \
+ -DLWS_WITH_ZIP_FOPS=0 -DLWS_WITH_ZLIB=0
+```
+The example shows how to build with no external cross lib dependencies, you
+need to provide the cross libraries otherwise.
+
+**NOTE**: start from an EMPTY build directory if you had a non-cross build in there
+ before the settings will be cached and your changes ignored.
+ Delete `build/CMakeCache.txt` at least before trying a new cmake config
+ to ensure you are really building the options you think you are.
+
+Additional information on cross compilation with CMake:
+ http://www.vtk.org/Wiki/CMake_Cross_Compiling
+
+@section cross_example Complex Cross compiling example
+
+Here are step by step instructions for cross-building the external projects needed for lws with lwsws + mbedtls as an example.
+
+In the example, my toolchain lives in `/projects/aist-tb/arm-tc` and is named `arm-linux-gnueabihf`. So you will need to adapt those to where your toolchain lives and its name where you see them here.
+
+Likewise I do all this in /tmp but it has no special meaning, you can adapt that to somewhere else.
+
+All "foreign" cross-built binaries are sent into `/tmp/cross` so they cannot be confused for 'native' x86_64 stuff on your host machine in /usr/[local/]....
+
+## Prepare the cmake toolchain file
+

+## Need for CI
+
+Generally if we're adding something that's supposed to work ongoing, the stuff
+should be exercised in CI (at least Travis).
+
+If there are few users for a particular feature, experience has shown that
+refactors or other upheaval can easily break it into a state of uselessness
+without anyone noticing until later.
+
+Therefore here's a description of how to add something to the CI tests... this
+is certainly a nonproductive PITA and I have never been thanked for the work
+involved. But if the promise of the various features working is going to
+remain alive, it's necessary to include CI test where possible with new
+nontrivial code.

Notes about coding with lws
===========================
+@section era Old lws and lws v2.0
+
+Originally lws only supported the "manual" method of handling everything in the
+user callback found in test-server.c / test-server-http.c.
+
+Since v2.0, the need for most or all of this manual boilerplate has been
+eliminated: the protocols[0] http stuff is provided by a generic lib export
+`lws_callback_http_dummy()`. You can serve parts of your filesystem at part of
+the URL space using mounts, the dummy http callback will do the right thing.
+
+It's much preferred to use the "automated" v2.0 type scheme, because it's less
+code and it's easier to support.
+
+The minimal examples all use the modern, recommended way.
+
+If you just need generic serving capability, without the need to integrate lws
+to some other app, consider not writing any server code at all, and instead use
+the generic server `lwsws`, and writing your special user code in a standalone
+"plugin". The server is configured for mounts etc using JSON, see
+./READMEs/README.lwsws.md.
+
+Although the "plugins" are dynamically loaded if you use lwsws or lws built
+with libuv, actually they may perfectly well be statically included if that
+suits your situation better, eg, ESP32 test server, where the platform does
+not support processes or dynamic loading, just #includes the plugins
+one after the other and gets the same benefit from the same code.
+
+Isolating and collating the protocol code in one place also makes it very easy
+to maintain and understand.
+
+So it if highly recommended you put your protocol-specific code into the
+form of a "plugin" at the source level, even if you have no immediate plan to
+use it dynamically-loaded.
+
+@section writeable Only send data when socket writeable
+
+You should only send data on a websocket connection from the user callback
+`LWS_CALLBACK_SERVER_WRITEABLE` (or `LWS_CALLBACK_CLIENT_WRITEABLE` for
+clients).
+
+If you want to send something, do NOT just send it but request a callback
+when the socket is writeable using
+
+ - `lws_callback_on_writable(wsi)` for a specific `wsi`, or
+
+ - `lws_callback_on_writable_all_protocol(protocol)` for all connections
+using that protocol to get a callback when next writeable.
+
+Usually you will get called back immediately next time around the service
+loop, but if your peer is slow or temporarily inactive the callback will be
+delayed accordingly. Generating what to write and sending it should be done
+in the ...WRITEABLE callback.
+
+See the test server code for an example of how to do this.
+
+Otherwise evolved libs like libuv get this wrong, they will allow you to "send"
+anything you want but it only uses up your local memory (and costs you
+memcpys) until the socket can actually accept it. It is much better to regulate
+your send action by the downstream peer readiness to take new data in the first
+place, avoiding all the wasted buffering.
+
+Libwebsockets' concept is that the downstream peer is truly the boss, if he,
+or our connection to him, cannot handle anything new, we should not generate
+anything new for him. This is how unix shell piping works, you may have
+`cat a.txt | grep xyz > remote", but actually that does not cat anything from
+a.txt while remote cannot accept anything new.
+
+@section oneper Only one lws_write per WRITEABLE callback
+
+From v2.5, lws strictly enforces only one lws_write() per WRITEABLE callback.
+
+You will receive a message about "Illegal back-to-back write of ... detected"
+if there is a second lws_write() before returning to the event loop.
+
+This is because with http/2, the state of the network connection carrying a
+wsi is unrelated to any state of the wsi. The situation on http/1 where a
+new request implied a new tcp connection and new SSL buffer, so you could
+assume some window for writes is no longer true. Any lws_write() can fail
+and be buffered for completion by lws; it will be auto-completed by the
+event loop.
+
+Note that if you are handling your own http responses, writing the headers
+needs to be done with a separate lws_write() from writing any payload. That
+means after writing the headers you must call `lws_callback_on_writable(wsi)`
+and send any payload from the writable callback.
+
+@section otherwr Do not rely on only your own WRITEABLE requests appearing
+
+Libwebsockets may generate additional `LWS_CALLBACK_CLIENT_WRITEABLE` events
+if it met network conditions where it had to buffer your send data internally.
+
+So your code for `LWS_CALLBACK_CLIENT_WRITEABLE` needs to own the decision
+about what to send, it can't assume that just because the writeable callback
+came something is ready to send.
+
+It's quite possible you get an 'extra' writeable callback at any time and
+just need to `return 0` and wait for the expected callback later.
+
@section dae Daemonization
There's a helper api `lws_daemonize` built by default that does everything you
Notice stdout, stderr, stdin are all redirected to /dev/null to enforce your
daemon is headless, so you'll need to sort out alternative logging, by, eg,
-syslog.
-
+syslog via `lws_set_log_level(..., lwsl_emit_syslog)`.
@section conns Maximum number of connections
similar to change the available number of file descriptors, and when restarted
**libwebsockets** will adapt accordingly.
+@section peer_limits optional LWS_WITH_PEER_LIMITS
+
+If you select `LWS_WITH_PEER_LIMITS` at cmake, then lws will track peer IPs
+and monitor how many connections and ah resources they are trying to use
+at one time. You can choose to limit these at context creation time, using
+`info.ip_limit_ah` and `info.ip_limit_wsi`.
+
+Note that although the ah limit is 'soft', ie, the connection will just wait
+until the IP is under the ah limit again before attaching a new ah, the
+wsi limit is 'hard', lws will drop any additional connections from the
+IP until it's under the limit again.
+
+If you use these limits, you should consider multiple clients may simultaneously
+try to access the site through NAT, etc. So the limits should err on the side
+of being generous, while still making it impossible for one IP to exhaust
+all the server resources.
@section evtloop Libwebsockets is singlethreaded
-Libwebsockets works in a serialized event loop, in a single thread.
+Libwebsockets works in a serialized event loop, in a single thread. It supports
+the default poll() backend, and libuv, libev, and libevent event loop
+libraries that also take this locking-free, nonblocking event loop approach that
+is not threadsafe. There are several advantages to this technique, but one
+disadvantage, it doesn't integrate easily if there are multiple threads that
+want to use libwebsockets.
-Directly performing websocket actions from other threads is not allowed.
-Aside from the internal data being inconsistent in `forked()` processes,
-the scope of a `wsi` (`struct websocket`) can end at any time during service
-with the socket closing and the `wsi` freed.
+However integration to multithreaded apps is possible if you follow some guidelines.
-Websocket write activities should only take place in the
-`LWS_CALLBACK_SERVER_WRITEABLE` callback as described below.
+1) Aside from two APIs, directly calling lws apis from other threads is not allowed.
-[This network-programming necessity to link the issue of new data to
-the peer taking the previous data is not obvious to all users so let's
-repeat that in other words:
+2) If you want to keep a list of live wsi, you need to use lifecycle callbacks on
+the protocol in the service thread to manage the list, with your own locking.
+Typically you use an ESTABLISHED callback to add ws wsi to your list and a CLOSED
+callback to remove them.
-***ONLY DO LWS_WRITE FROM THE WRITEABLE CALLBACK***
+3) LWS regulates your write activity by being able to let you know when you may
+write more on a connection. That reflects the reality that you cannot succeed to
+send data to a peer that has no room for it, so you should not generate or buffer
+write data until you know the peer connection can take more.
-There is another network-programming truism that surprises some people which
-is if the sink for the data cannot accept more:
+Other libraries pretend that the guy doing the writing is the boss who decides
+what happens, and absorb as much as you want to write to local buffering. That does
+not scale to a lot of connections, because it will exhaust your memory and waste
+time copying data around in memory needlessly.
-***YOU MUST PERFORM RX FLOW CONTROL***
+The truth is the receiver, along with the network between you, is the boss who
+decides what will happen. If he stops accepting data, no data will move. LWS is
+designed to reflect that.
-See the mirror protocol implementations for example code.
+If you have something to send, you call `lws_callback_on_writable()` on the
+connection, and when it is writeable, you will get a `LWS_CALLBACK_SERVER_WRITEABLE`
+callback, where you should generate the data to send and send it with `lws_write()`.
-Only live connections appear in the user callbacks, so this removes any
-possibility of trying to used closed and freed wsis.
+You cannot send data using `lws_write()` outside of the WRITEABLE callback.
-If you need to service other socket or file descriptors as well as the
-websocket ones, you can combine them together with the websocket ones
-in one poll loop, see "External Polling Loop support" below, and
-still do it all in one thread / process context.
+4) For multithreaded apps, this corresponds to a need to be able to provoke the
+`lws_callback_on_writable()` action and to wake the service thread from its event
+loop wait (sleeping in `poll()` or `epoll()` or whatever). The rules above
+mean directly sending data on the connection from another thread is out of the
+question.
-If you insist on trying to use it from multiple threads, take special care if
-you might simultaneously create more than one context from different threads.
+Therefore the two apis mentioned above that may be used from another thread are
-SSL_library_init() is called from the context create api and it also is not
-reentrant. So at least create the contexts sequentially.
+ - For LWS using the default poll() event loop, `lws_callback_on_writable()`
+ - For LWS using libuv/libev/libevent event loop, `lws_cancel_service()`
-@section writeable Only send data when socket writeable
+If you are using the default poll() event loop, one "foreign thread" at a time may
+call `lws_callback_on_writable()` directly for a wsi. You need to use your own
+locking around that to serialize multiple thread access to it.
-You should only send data on a websocket connection from the user callback
-`LWS_CALLBACK_SERVER_WRITEABLE` (or `LWS_CALLBACK_CLIENT_WRITEABLE` for
-clients).
+If you implement LWS_CALLBACK_GET_THREAD_ID in protocols[0], then LWS will detect
+when it has been called from a foreign thread and automatically use
+`lws_cancel_service()` to additionally wake the service loop from its wait.
-If you want to send something, do not just send it but request a callback
-when the socket is writeable using
+For libuv/libev/libevent event loop, they cannot handle being called from other
+threads. So there is a slightly different scheme, you may call `lws_cancel_service()`
+to force the event loop to end immediately. This then broadcasts a callback (in the
+service thread context) `LWS_CALLBACK_EVENT_WAIT_CANCELLED`, to all protocols on all
+vhosts, where you can perform your own locking and walk a list of wsi that need
+`lws_callback_on_writable()` calling on them.
- - `lws_callback_on_writable(context, wsi)` for a specific `wsi`, or
-
- - `lws_callback_on_writable_all_protocol(protocol)` for all connections
-using that protocol to get a callback when next writeable.
+`lws_cancel_service()` is very cheap to call.
-Usually you will get called back immediately next time around the service
-loop, but if your peer is slow or temporarily inactive the callback will be
-delayed accordingly. Generating what to write and sending it should be done
-in the ...WRITEABLE callback.
+5) The obverse of this truism about the receiver being the boss is the case where
+we are receiving. If we get into a situation we actually can't usefully
+receive any more, perhaps because we are passing the data on and the guy we want
+to send to can't receive any more, then we should "turn off RX" by using the
+RX flow control API, `lws_rx_flow_control(wsi, 0)`. When something happens where we
+can accept more RX, (eg, we learn our onward connection is writeable) we can call
+it again to re-enable it on the incoming wsi.
-See the test server code for an example of how to do this.
+LWS stops calling back about RX immediately you use flow control to disable RX, it
+buffers the data internally if necessary. So you will only see RX when you can
+handle it. When flow control is disabled, LWS stops taking new data in... this makes
+the situation known to the sender by TCP "backpressure", the tx window fills and the
+sender finds he cannot write any more to the connection.
+See the mirror protocol implementations for example code.
-@section otherwr Do not rely on only your own WRITEABLE requests appearing
+If you need to service other socket or file descriptors as well as the
+websocket ones, you can combine them together with the websocket ones
+in one poll loop, see "External Polling Loop support" below, and
+still do it all in one thread / process context. If the need is less
+architectural, you can also create RAW mode client and serving sockets; this
+is how the lws plugin for the ssh server works.
-Libwebsockets may generate additional `LWS_CALLBACK_CLIENT_WRITEABLE` events
-if it met network conditions where it had to buffer your send data internally.
+@section anonprot Working without a protocol name
-So your code for `LWS_CALLBACK_CLIENT_WRITEABLE` needs to own the decision
-about what to send, it can't assume that just because the writeable callback
-came it really is time to send something.
+Websockets allows connections to negotiate without a protocol name...
+in that case by default it will bind to the first protocol in your
+vhost protocols[] array.
-It's quite possible you get an 'extra' writeable callback at any time and
-just need to `return 0` and wait for the expected callback later.
+You can tell the vhost to use a different protocol by attaching a
+pvo (per-vhost option) to the
+
+```
+/*
+ * this sets a per-vhost, per-protocol option name:value pair
+ * the effect is to set this protocol to be the default one for the vhost,
+ * ie, selected if no Protocol: header is sent with the ws upgrade.
+ */
+
+static const struct lws_protocol_vhost_options pvo_opt = {
+ NULL,
+ NULL,
+ "default",
+ "1"
+};
+
+static const struct lws_protocol_vhost_options pvo = {

+and allow interface code to manage socket descriptors in other poll loops.
You can pass all pollfds that need service to `lws_service_fd()`, even
if the socket or file does not belong to **libwebsockets** it is safe.
- use LWS_POLLHUP / LWS_POLLIN / LWS_POLLOUT from libwebsockets.h to avoid
losing windows compatibility
+You also need to take care about "forced service" somehow... these are cases
+where the network event was consumed, incoming data was all read, for example,
+but the work arising from it was not completed. There will not be any more
+network event to trigger the remaining work, Eg, we read compressed data, but
+we did not use up all the decompressed data before returning to the event loop
+because we had to write some of it.
+
+Lws provides an API to determine if anyone is waiting for forced service,
+`lws_service_adjust_timeout(context, 1, tsi)`, normally tsi is 0. If it returns
+0, then at least one connection has pending work you can get done by calling
+`lws_service_tsi(context, -1, tsi)`, again normally tsi is 0.
+
+For eg, the default poll() event loop, or libuv/ev/event, lws does this
+checking for you and handles it automatically. But in the external polling
+loop case, you must do it explicitly. Handling it after every normal service
+triggered by the external poll fd should be enough, since the situations needing
+it are initially triggered by actual network events.
+
+An example of handling it is shown in the test-server code specific to
+external polling.

```

whole time.
+@section http2compat Code Requirements for HTTP/2 compatibility
+
+Websocket connections only work over http/1, so there is nothing special to do
+when you want to enable -DLWS_WITH_HTTP2=1.
+
+The internal http apis already follow these requirements and are compatible with
+http/2 already. So if you use stuff like mounts and serve stuff out of the
+filesystem, there's also nothing special to do.
+
+However if you are getting your hands dirty with writing response headers, or
+writing bulk data over http/2, you need to observe these rules so that it will
+work over both http/1.x and http/2 the same.
+
+1) LWS_PRE requirement applies on ALL lws_write(). For http/1, you don't have
+to take care of LWS_PRE for http data, since it is just sent straight out.
+For http/2, it will write up to LWS_PRE bytes behind the buffer start to create
+the http/2 frame header.
+
+This has implications if you treated the input buffer to lws_write() as const...
+it isn't any more with http/2, up to 9 bytes behind the buffer will be trashed.
+
+2) Headers are encoded using a sophisticated scheme in http/2. The existing
+header access apis are already made compatible for incoming headers,
+for outgoing headers you must:
+
+ - observe the LWS_PRE buffer requirement mentioned above
+
+ - Use `lws_add_http_header_status()` to add the transaction status (200 etc)
+
+ - use lws apis `lws_add_http_header_by_name()` and `lws_add_http_header_by_token()`
+ to put the headers into the buffer (these will translate what is actually
+ written to the buffer depending on if the connection is in http/2 mode or not)
+
+ - use the `lws api lws_finalize_http_header()` api after adding the last
+ response header
+
+ - write the header using lws_write(..., `LWS_WRITE_HTTP_HEADERS`);
+
+ 3) http/2 introduces per-stream transmit credit... how much more you can send
+ on a stream is decided by the peer. You start off with some amount, as the
+ stream sends stuff lws will reduce your credit accordingly, when it reaches
+ zero, you must not send anything further until lws receives "more credit" for
+ that stream the peer. Lws will suppress writable callbacks if you hit 0 until
+ more credit for the stream appears, and lws built-in file serving (via mounts
+ etc) already takes care of observing the tx credit restrictions. However if
+ you write your own code that wants to send http data, you must consult the
+ `lws_get_peer_write_allowance()` api to find out the state of your tx credit.
+ For http/1, it will always return (size_t)-1, ie, no limit.
+
+ This is orthogonal to the question of how much space your local side's kernel
+ will make to buffer your send data on that connection. So although the result
+ from `lws_get_peer_write_allowance()` is "how much you can send" logically,
+ and may be megabytes if the peer allows it, you should restrict what you send
+ at one time to whatever your machine will generally accept in one go, and
+ further reduce that amount if `lws_get_peer_write_allowance()` returns
+ something smaller. If it returns 0, you should not consume or send anything
+ and return having asked for callback on writable, it will only come back when
+ more tx credit has arrived for your stream.
+
+ 4) Header names with captital letters are illegal in http/2. Header names in
+ http/1 are case insensitive. So if you generate headers by name, change all
+ your header name strings to lower-case to be compatible both ways.
+
+ 5) Chunked Transfer-encoding is illegal in http/2, http/2 peers will actively
+ reject it. Lws takes care of removing the header and converting CGIs that
+ emit chunked into unchunked automatically for http/2 connections.
+
+If you follow these rules, your code will automatically work with both http/1.x
+and http/2.
@section ka TCP Keepalive
You can also set it to `"ALL"` to allow everything (including insecure ciphers).
+@section sslcerts Passing your own cert information direct to SSL_CTX
+
+For most users it's enough to pass the SSL certificate and key information by
+giving filepaths to the info.ssl_cert_filepath and info.ssl_private_key_filepath
+members when creating the vhost.
+
+If you want to control that from your own code instead, you can do so by leaving
+the related info members NULL, and setting the info.options flag
+LWS_SERVER_OPTION_CREATE_VHOST_SSL_CTX at vhost creation time. That will create
+the vhost SSL_CTX without any certificate, and allow you to use the callback
+LWS_CALLBACK_OPENSSL_LOAD_EXTRA_SERVER_VERIFY_CERTS to add your certificate to
+the SSL_CTX directly. The vhost SSL_CTX * is in the user parameter in that
+callback.

+@section rawudp RAW UDP socket integration
+
+Lws provides an api to create, optionally bind, and adopt a RAW UDP
+socket (RAW here means an uninterpreted normal UDP socket, not a
+"raw socket").
+
+```
+LWS_VISIBLE LWS_EXTERN struct lws *
+lws_create_adopt_udp(struct lws_vhost *vhost, int port, int flags,
+ const char *protocol_name, struct lws *parent_wsi);
+```
+
+`flags` should be `LWS_CAUDP_BIND` if the socket will receive packets.
+
+The callbacks `LWS_CALLBACK_RAW_ADOPT`, `LWS_CALLBACK_RAW_CLOSE`,
+`LWS_CALLBACK_RAW_RX` and `LWS_CALLBACK_RAW_WRITEABLE` apply to the
+wsi. But UDP is different than TCP in some fundamental ways.
+
+For receiving on a UDP connection, data becomes available at
+`LWS_CALLBACK_RAW_RX` as usual, but because there is no specific
+connection with UDP, it is necessary to also get the source address of
+the data separately, using `struct lws_udp * lws_get_udp(wsi)`.
+You should take a copy of the `struct lws_udp` itself (not the
+pointer) and save it for when you want to write back to that peer.
+
+Writing is also a bit different for UDP. By default, the system has no
+idea about the receiver state and so asking for a `callback_on_writable()`
+always believes that the socket is writeable... the callback will
+happen next time around the event loop.
+
+With UDP, there is no single "connection". You need to write with sendto() and
+direct the packets to a specific destination. To return packets to a
+peer who sent something earlier and you copied his `struct lws_udp`, you
+use the .sa and .salen members as the last two parameters of the sendto().
+
+The kernel may not accept to buffer / write everything you wanted to send.
+So you are responsible to watch the result of sendto() and resend the
+unsent part next time (which may involve adding new protocol headers to
+the remainder depending on what you are doing).

+In addition building anything with libev using gcc spews warnings, the

+
+For these reasons and the response I got trying to raise these issues with

@section extopts Extension option control from user code
this is not normally done if the vhost was set up to listen / serve. Call
the api lws_init_vhost_client_ssl() to also allow client SSL on the vhost.
+@section clipipe Pipelining Client Requests to same host
+
+If you are opening more client requests to the same host and port, you
+can give the flag LCCSCF_PIPELINE on `info.ssl_connection` to indicate
+you wish to pipeline them.
+
+Without the flag, the client connections will occur concurrently using a
+socket and tls wrapper if requested for each connection individually.
+That is fast, but resource-intensive.
+
+With the flag, lws will queue subsequent client connections on the first
+connection to the same host and port. When it has confirmed from the
+first connection that pipelining / keep-alive is supported by the server,
+it lets the queued client pipeline connections send their headers ahead
+of time to create a pipeline of requests on the server side.
+
+In this way only one tcp connection and tls wrapper is required to transfer
+all the transactions sequentially. It takes a little longer but it
+can make a significant difference to resources on both sides.
+If lws learns from the first response header that keepalive is not possible,
+then it marks itself with that information and detaches any queued clients
+to make their own individual connections as a fallback.
+
+Lws can also intelligently combine multiple ongoing client connections to
+the same host and port into a single http/2 connection with multiple
+streams if the server supports it.
+
+Unlike http/1 pipelining, with http/2 the client connections all occur
+simultaneously using h2 stream multiplexing inside the one tcp + tls
+connection.
+
+You can turn off the h2 client support either by not building lws with
+`-DLWS_WITH_HTTP2=1` or giving the `LCCSCF_NOT_H2` flag in the client
+connection info struct `ssl_connection` member.
@section vhosts Using lws vhosts

CALLBACK area matches it).
+This "binding connection to a protocol" lifecycle in managed by

+Because of HTTP/1.1 connection pipelining, one connection may perform
+many transactions, each of which may map to different URLs and need
+binding to different protocols. So these messages are used to
+create the binding of the wsi to your protocol including any
+allocations, and to destroy the binding, at which point you should
+destroy any related allocations.

- dim the page during initialization, in a script section on your page

+
+@section errstyle Styling http error pages
+
+In the code, http errors should be handled by `lws_return_http_status()`.
+
+There are basically two ways... the vhost can be told to redirect to an "error
+page" URL in response to specifically a 404... this is controlled by the
+context / vhost info struct (`struct lws_context_creation_info`) member
+`.error_document_404`... if non-null the client is redirected to this string.
+
+If it wasn't redirected, then the response code html is synthesized containing
+the user-selected text message and attempts to pull in `/error.css` for styling.
+
+If this file exists, it can be used to style the error page. See
+https://libwebsockets.org/git/badrepo for an example of what can be done (
+and https://libwebsockets.org/error.css for the corresponding css).

+## Using Content Security Policy (CSP)
+
+### What is it?
+
+Modern browsers have recently implemented a new feature providing
+a sort of "selinux for your web page". If the server sends some
+new headers describing the security policy for the content, then
+the browser strictly enforces it.
+
+### Why would we want to do that?
+
+Scripting on webpages is pretty universal, sometimes the scripts
+come from third parties, and sometimes attackers find a way to
+inject scripts into the DOM, eg, through scripts in content.
+
+CSP lets the origin server define what is legitimate for the page it
+served and everything else is denied.
+
+The CSP for warmcat.com and libwebsockets.org looks like this,
+I removed a handful of whitelisted image sources like travis
+status etc for clarity...
+
+```
+"content-security-policy": "default-src 'none'; img-src 'self' data:; script-src 'self'; font-src 'self'; style-src 'self'; connect-src 'self'; frame-ancestors 'none'; base-uri 'none';",
+"x-content-type-options": "nosniff",
+"x-xss-protection": "1; mode=block",
+"x-frame-options": "deny",
+"referrer-policy": "no-referrer"
+```
+
+The result of this is the browser won't let the site content be iframed, and it
+will reject any inline styles or inline scripts. Fonts, css, ajax, ws and
+images are only allowed to come from 'self', ie, the server that served the
+page. You may inject your script, or deceptive styles: it won't run or be shown.
+
+Because inline scripts are banned, the usual methods for XSS are dead;
+the attacker can't even load js from another server. So these rules
+provide a very significant increase in client security.
+
+### Implications of strict CSP
+
+Halfhearted CSP isn't worth much. The only useful approach is to start
+with `default-src 'none'` which disables everything, and then whitelist the
+minimum needed for the pages to operate.
+
+"Minimum needed for the pages to operate" doesn't mean defeat the protections
+necessary so everything in the HTML can stay the same... it means adapt the
+pages to want the minimum and then enable the minimum.
+
+The main point is segregation of styles and script away from the content, in
+files referenced in the document `<head>` section, along these lines:
+
+```
+<head>
+ <meta charset=utf-8 http-equiv="Content-Language" content="en"/>
+ <link rel="stylesheet" type="text/css" href="test.css"/>
+ <script type='text/javascript' src="/lws-common.js"></script>
+ <script type='text/javascript' src='test.js'></script>
+ <title>Minimal Websocket test app</title>
+</head>
+```
+
+#### Inline styles must die
+
+All styling must go in one or more `.css` file(s) best served by the same
+server... while you can whitelist other sources in the CSP if you have to,
+unless you control that server as well, you are allowing whoever gains
+access to that server access to your users.
+
+Inline styles are no longer allowed (eg, "style='font-size:120%'" in the
+HTML)... they must be replaced by reference to one or more CSS class, which
+in this case includes "font-size:120%". This has always been the best
+practice anyway, and your pages will be cleaner and more maintainable.
+
+#### Inline scripts must die
+
+Inline scripts need to be placed in a `.js` file and loaded in the page head
+section, again it should only be from the server that provided the page.
+
+Then, any kind of inline script, yours or injected or whatever, will be
+completely rejected by the browser.
+
+#### onXXX must be replaced by eventListener
+
+Inline `onclick()` etc are kinds of inline scripting and are banned.
+
+Modern browsers have offered a different system called ["EventListener" for
+a while](https://developer.mozilla.org/en-US/docs/Web/API/EventListener)
+which allows binding of events to DOM elements in JS.
+
+A bunch of different named events are possible to listen on, commonly the
+`.js` file will ask for one or both of
+
+```
+window.addEventListener("load", function() {
+...
+}, false);
+
+document.addEventListener("DOMContentLoaded", function() {
+...
+}, false);
+```
+
+These give the JS a way to trigger when either everything on the page has
+been "loaded" or the DOM has been populated from the initial HTML. These
+can set up other event listeners on the DOM objects and aftwards the
+events will drive what happens on the page from user interaction and / or
+timers etc.
+
+If you have `onclick` in your HTML today, you would replace it with an id
+for the HTML element, then eg in the DOMContentLoaded event listener,
+apply
+
+```
+ document.getElementById("my-id").addEventListener("click", function() {
+ ...
+ }, false);
+```
+
+ie the .js file becomes the only place with the "business logic" of the
+elements mentioned in the HTML, applied at runtime.
+
+#### Do you really need external sources?
+
+Do your scripts and fonts really need to come from external sources?
+If your caching policy is liberal, they are not actually that expensive
+to serve once and then the user is using his local copy for the next
+days.
+
+Some external sources are marked as anti-privacy in modern browsers, meaning
+they track your users, in turn meaning if your site refers to them, you
+will lose your green padlock in the browser. If the content license allows
+it, hosting them on "self", ie, the same server that provided the HTML,
+will remove that problem.
+
+Bringing in scripts from external sources is actually quite scary from the
+security perspective. If someone hacks the `ajax.googleapis.com` site to serve
+a hostile, modified jquery, half the Internet will instantly
+become malicious. However if you serve it yourself, unless your server
+was specifically targeted you know it will continue to serve what you
+expect.
+
+Since these scripts are usually sent with cache control headers for local
+caching duration of 1 year, the cost of serving them yourself under the same
+conditions is small but your susceptibility to attack is reduced to only taking
+care of your own server. And there is a privacy benefit that google is not
+informed of your users' IPs and activities on your site.

+## Contributing to lws
+
+### How to contribute
+
+Sending a patch with a bug report is very welcome.
+
+For nontrivial problems, it's probably best to discuss on the mailing list,
+or on github if you prefer, how to best solve it.
+
+However your contribution is coming is fine:
+
+ - paste a `git diff`
+
+ - send a patch series by mail or mailing list
+
+ - paste in a github issue
+
+ - github PR
+
+are all OK.
+
+### Coding Standards
+
+Code should look roughly like the existing code, which follows linux kernel
+coding style.
+
+If there are non-functional problems I will clean them out when I apply the
+patch.
+
+If there are functional problems (eg broken error paths etc) if they are
+small compared to the working part I will also clean them. If there are
+larger problems, or consequences to the patch will have to discuss how to
+solve them with a retry.
+
+### Funding specific work
+
+If there is a feature you wish was supported in lws, consider paying for the
+work to be done. The maintainer is a consultant and if we can agree the
+task, you can quickly get a high quality result that does just what you need,
+maintained ongoing along with the rest of lws.

+# Lws Crypto Apis
+
+## Overview
+
+
+
+Lws provides a "generic" crypto layer on top of both OpenSSL and
+compatible tls library, and mbedtls. Using this layer, your code
+can work without any changes on both types of tls library crypto
+backends... it's as simple as rebuilding lws with `-DLWS_WITH_MBEDTLS=0`
+or `=1` at cmake.
+
+The generic layer can be used directly (as in, eg, the sshd plugin),
+or via another layer on top, which processes JOSE JSON objects using
+JWS (JSON Web Signatures), JWK (JSON Web Keys), and JWE (JSON Web
+Encryption).
+
+The `JW` apis use the generic apis (`lws_genrsa_`, etc) to get the crypto tasks
+done, so anything they can do you can also get done using the generic apis.
+The main difference is that with the generic apis, you must instantiate the
+correct types and use type-specfic apis. With the `JW` apis, there is only
+one interface for all operations, with the details hidden in the api and
+controlled by the JSON objects.
+
+Because of this, the `JW` apis are often preferred because they give you
+"crypto agility" cheaply... to change your crypto to another supported algorithm
+once it's working, you literally just change your JSON defining the keys and
+JWE or JWS algorithm. (It's up to you to define your policy for which
+combinations are acceptable by querying the parsed JW structs).

+### Keys in the generic layer
+
+The necessary types and defines are brought in by `libwebsockets.h`.
+
+Keys are represented only by an array of `struct lws_jwk_elements`... the
+length of the array is defined by the cipher... it's one of
+
+|key elements count|definition|
+|---|---|
+|`LWS_COUNT_OCT_KEY_ELEMENTS`|1|
+|`LWS_COUNT_RSA_KEY_ELEMENTS`|8|
+|`LWS_COUNT_EC_KEY_ELEMENTS`|4|
+|`LWS_COUNT_AES_KEY_ELEMENTS`|1|
+
+`struct lws_jwk_elements` is a simple pointer / length combination used to
+store arbitrary octets that make up the key element's binary representation.
+
+## Using the JOSE layer
+
+The JOSE (JWK / JWS / JWE) stuff is a crypto-agile JSON-based layer
+that uses the gencrypto support underneath.
+
+"Crypto Agility" means the JSON structs include information about the
+algorithms and ciphers used in that particular object, making it easy to
+upgrade system crypto strength or cycle keys over time while supporting a
+transitional period where the old and new keys or algorithms + ciphers
+are also valid.
+
+Uniquely lws generic support means the JOSE stuff also has "tls library
+agility", code written to the lws generic or JOSE apis is completely unchanged
+even if the underlying tls library changes between OpenSSL and mbedtls, meaning
+sharing code between server and client sides is painless.
+
+All the necessary includes are part of `libwebsockets.h`.
+
+Enable `-DLWS_WITH_JOSE=1` at CMake.

+
+### Keys in the JOSE layer
+
+Keys in the JOSE layer use a `struct lws_jwk`, this contains two arrays of
+`struct lws_jwk_elements` sized for the worst case (currently RSA). One
+array contains the key elements as described for the generic case, and the
+other contains various nonencrypted key metadata taken from JWK JSON.
+
+|metadata index|function|
+|---|---|
+|`JWK_META_KTY`|Key type, eg, "EC"|
+|`JWK_META_KID`|Arbitrary ID string|
+|`JWK_META_USE`|What the public key may be used to validate, "enc" or "sig"|
+|`JWK_META_KEY_OPS`|Which operations the key is authorized for, eg, "encrypt"|
+|`JWK_META_X5C`|Optional X.509 cert version of the key|
+|`JWK_META_ALG`|Optional overall crypto algorithm the key is intended for use with|
+
+`lws_jwk_destroy()` should be called when the jwk is going out of scope... this
+takes care to zero down any key element data in the jwk.
+
ESP32 Support
=============
+See \ref esp32 for details on how to build lws as a component in an ESP-IDF project.
+
Lws provides a "factory" application
https://github.com/warmcat/lws-esp32-factory
User configuration|Factory|AP: config-model-serial|443|https://192.168.4.1|index.html - user set up his AP information
Operation|OTA|Station only|443|https://model-serial.local|OTA application
+## Basic Auth
+
+The lws-esp32-test-server-demos app also demos basic auth.
+
+On a normal platform this is done by binding a mount to a text file somewhere in the filesystem, which
+contains user:password information one per line.
+
+On ESP32 there is not necessarily any generic VFS in use. So instead, the basic auth lookup is bound to
+a given nvs domain, where the username is the key and the password the value. main/main.c in the test
+demos app shows how to both make the mount use basic auth, and how to set a user:password combination
+using nvs.

+# Http fallback and raw proxying
+
+Lws has several interesting options and features that can be applied to get
+some special behaviours... this article discusses them and how they work.
+
+## Overview of normal vhost selection
+
+Lws supports multiple http or https vhosts sharing a listening socket on the
+same port.
+
+For unencrypted http, the Host: header is used to select which vhost the
+connection should bind to, by comparing what is given there against the
+names the server was configured with for the various vhosts. If no match, it
+selects the first configured vhost.
+
+For TLS, it has an extension called SNI (Server Name Indication) which tells
+the server early in the TLS handshake the host name the connection is aimed at.
+That allows lws to select the vhost early, and use vhost-specific TLS certs
+so everything is happy. Again, if there is no match the connection proceeds
+using the first configured vhost and its certs.
+
+## Http(s) fallback options
+
+What happens if you try to connect, eg, an ssh client to the http server port
+(this is not an idle question...)? Obviously the http server part or the tls
+part of lws will fail the connection and close it. (We will look at that flow
+in a moment in detail for both unencrypted and tls listeners.)
+
+However if the first configured vhost for the port was created with the
+vhost creation info struct `.options` flag `LWS_SERVER_OPTION_FALLBACK_TO_APPLY_LISTEN_ACCEPT_CONFIG`,
+then instead of the error, the connection transitions to whatever role was
+given in the vhost creation info struct `.listen_accept_role` and `.listen_accept_protocol`.
+
+With lejp-conf / lwsws, the options can be applied to the first vhost using:
+
+```
+ "listen-accept-role": "the-role-name",
+ "listen-accept-protocol": "the-protocol-name",
+ "fallback-listen-accept": "1"
+```
+
+See `./minimal-examples/raw/minimal-raw-fallback-http-server` for examples of
+all the options in use via commandline flags.
+
+So long as the first packet for the protocol doesn't look like GET, POST, or
+a valid tls packet if connection to an https vhost, this allows the one listen
+socket to handle both http(s) and a second protocol, as we will see, like ssh.
+
+Notice there is a restriction that no vhost selection processing is possible,
+neither for tls listeners nor plain http ones... the packet belonging to a
+different protocol will not send any Host: header nor tls SNI.
+
+Therefore although the flags and settings are applied to the first configured
+vhost, actually their effect is global for a given listen port. If enabled,
+all vhosts on the same listen port will do the fallback action.
+
+### Plain http flow
+
+
+
+Normally, if the first received packet does not contain a valid HTTP method,
+then the connection is dropped. Which is what you want from an http server.
+
+However if enabled, the connection can transition to the defined secondary
+role / protocol.
+
+|Flag|lejp-conf / lwsws|Function|
+|---|---|---|
+|`LWS_SERVER_OPTION_FALLBACK_TO_APPLY_LISTEN_ACCEPT_CONFIG`|`"fallback-listen-accept": "1"`|Enable fallback processing|
+
+### TLS https flow
+
+
+
+If the port is listening with tls, the point that a packet from a different
+protocol will fail is earlier, when the tls tunnel is being set up.
+
+|Flag|lejp-conf / lwsws|Function|
+|---|---|---|
+|`LWS_SERVER_OPTION_FALLBACK_TO_APPLY_LISTEN_ACCEPT_CONFIG`|`"fallback-listen-accept": "1"`|Enable fallback processing|
+|`LWS_SERVER_OPTION_REDIRECT_HTTP_TO_HTTPS`|`"redirect-http": "1"`|Treat invalid tls packet as http, issue http redirect to https://|
+|`LWS_SERVER_OPTION_ALLOW_HTTP_ON_HTTPS_LISTENER`|`"allow-http-on-https": "1"`|Accept unencrypted http connections on this tls port (dangerous)|
+
+The latter two options are higher priority than, and defeat, the first one.
+
+### Non-http listener
+
+
+
+It's also possible to skip the fallback processing and just force the first
+vhost on the port to use the specified role and protocol in the first place.
+
+|Flag|lejp-conf / lwsws|Function|
+|---|---|---|
+|LWS_SERVER_OPTION_ADOPT_APPLY_LISTEN_ACCEPT_CONFIG|`"apply-listen-accept": "1"`|Force vhost to use listen-accept-role / listen-accept-protocol|
+
+## Using http(s) fallback with raw-proxy
+
+If enabled for build with `cmake .. -DLWS_ROLE_RAW_PROXY=1 -DLWS_WITH_PLUGINS=1`
+then lws includes ready-to-use support for raw tcp proxying.
+
+This can be used standalone on the first vhost on a port, but most intriguingly
+it can be specified as the fallback for http(s)...
+
+See `./minimal-examples/raw/minimal-raw-proxy-fallback.c` for a working example.
+
+### fallback with raw-proxy in code
+
+On the first vhost for the port, specify the required "onward" pvo to configure
+the raw-proxy protocol...you can adjust the "ipv4:127.0.0.1:22" to whatever you
+want...
+
+```
+ static struct lws_protocol_vhost_options pvo1 = {
+ NULL,
+ NULL,
+ "onward", /* pvo name */
+ "ipv4:127.0.0.1:22" /* pvo value */
+ };
+
+ static const struct lws_protocol_vhost_options pvo = {
+ NULL, /* "next" pvo linked-list */
+ &pvo1, /* "child" pvo linked-list */
+ "raw-proxy", /* protocol name we belong to on this vhost */
+ "" /* ignored */
+ };
+```
+
+... and set up the fallback enable and bindings...
+
+```
+ info.options |= LWS_SERVER_OPTION_FALLBACK_TO_APPLY_LISTEN_ACCEPT_CONFIG;
+ info.listen_accept_role = "raw_proxy";
+ info.listen_accept_proxy = "raw_proxy";
+ info.pvo = &pvo;
+```
+
+### fallback with raw-proxy in JSON conf
+
+On the first vhost for the port, enable the raw-proxy protocol on the vhost and
+set the pvo config
+
+```
+ "ws-protocols": [{
+ "raw-proxy": {
+ "status": "ok",
+ "onward": "ipv4:127.0.0.1:22"
+ }
+ }],
+```
+
+Enable the fallback behaviour on the vhost and the role / protocol binding
+
+```
+ "listen-accept-role": "raw-proxy",
+ "listen-accept-protocol": "raw-proxy",
+ "fallback-listen-accept": "1"
+```
+
+### Testing
+
+With this configured, the listen port will function normally for http or https
+depending on how it was set up.
+
+But if you try to connect to it with an ssh client, that will also work fine.
+
+The libwebsockets.org server is set up in this way, you can confirm it by
+visiting `https://libwebsockets.org` on port 443 as usual, but also trying
+`ssh -p 443 invalid@libwebsockets.org`... you will get permission denied from
+your ssh client. With valid credentials in fact that works perfectly for
+ssh, scp, git-over-ssh etc all on port 443...

+# lws_dll Doubly-linked list
+
+## Introduction
+
+Lws supports two kinds of doubly-linked list, `lws_dll` and `lws_dll2`.
+
+Unless memory is at a big premium, or it has to work on lws < v3.2, it's
+best to simply use `lws_dll2`.
+
+
+
+## How to use
+
+The basics are the same for lws_dll and lws_dll2.
+
+The list objects point only to themselves, and you use the `lws_container_of`
+macro to get a pointer to your struct that contains the list object. Doing
+it this way
+
+ - the list object does not have to be the first thing in your struct
+
+ - your struct can contain multiple list objects and appear on lists belonging
+ to multiple owners simultaenously,
+
+### lws_dll Minimal example
+
+```
+struct mystruct {
+ ....
+ lws_dll list;
+ ...
+};
+
+lws_dll owner;
+```
+
+Adding a mystruct to the owner list (...add_tail() works the same way but adds
+to the other end of the list)
+
+```
+ struct mystruct *p;
+
+ ...
+
+ lws_dll_add_head(&p->list, &owner);
+```
+
+Removing the list object from its owner
+
+```
+ lws_dll2_remove(&p->list, &owner);
+```
+
+If you have a `struct lws_dll *d` pointing to `list` in struct mystruct, you can
+convert it to a `struct mystruct *p` ike this
+
+```
+ struct mystruct *p = lws_container_of(d, struct lws_dll, list);
+```
+
+### lws_dll2 Minimal example
+
+
+```
+struct mystruct {
+ ....
+ lws_dll2 list;
+ ...
+};
+
+lws_dll2_owner owner;
+```
+
+Adding a mystruct to the owner list (...add_tail() works the same way but adds
+to the other end of the list)
+
+```
+ struct mystruct *p;
+
+ ...
+
+ lws_dll2_add_head(&p->list, &owner);
+```
+
+Removing the list object from its owner (notice compared to lws_dll, it doesn't
+need to be told the owner)
+
+```
+ lws_dll2_remove(&p->list);
+```
+
+If you have a `struct lws_dll2 *d` pointing to `list` in struct mystruct, you
+can convert it to a `struct mystruct *p` ike this
+
+```
+ struct mystruct *p = lws_container_of(d, struct lws_dll2, list);
+```
+
+## Summary Comparing lws_dll and lws_dll2
+
+ - both offer a doubly-linked list object, and (since v3.2) track both the
+ head and tail in an "list owner" object
+
+ - both are initalized by memsetting to 0
+
+ - for `lws_dll`, it reuses an `lws_dll` as the "owner", for `lws_dll2`, there's a
+ specific `lws_dll2_owner` structure for that
+
+ - `lws_dll2_owner` also keeps count of the number of list elements
+
+ - `lws_dll2` knows which owner's list it is participating on. So it can remove
+ itself and update the owner without the caller needing to know its owner.
+ In the case there are several potential owners list objects may be on, this
+ is very convenient.
+
+ - `lws_dll` is simpler and has a smaller footprint (two pointers per entry vs
+ three). But you have to know the exact list owner to perform operations on
+ it.
+

+# `lws_sequencer_t` introduction
+
+Often a single network action like a client GET is just part of a
+larger series of actions, perhaps involving different connections.
+
+Since lws operates inside an event loop, if the outer sequencing
+doesn't, it can be awkward to synchronize these steps with what's
+happening on the network with a particular connection on the event
+loop thread.
+
+
+
+`lws_sequencer_t` provides a generic way to stage multi-step
+operations from inside the event loop. Because it participates
+in the event loop similar to a wsi, it always operates from the
+service thread context and can access structures that share the
+service thread without locking. It can also provide its own
+higher-level timeout handling.
+
+Naturally you can have many of them running in the same event
+loop operating independently.
+
+Sequencers themselves bind to a pt (per-thread) service thread,
+by default there's only one of these and it's the same as saying
+they bind to an `lws_context`. The sequencer callback may create
+wsi which in turn are bound to a vhost, but the sequencer itself
+is above all that.
+
+## Sequencer timeouts
+
+The sequencer additionally maintains its own second-resolution timeout
+checked by lws for the step being sequenced... this is independent of
+any lws wsi timeouts which tend to be set and reset for very short-term
+timeout protection inside one transaction.
+
+The sequencer timeout operates separately and above any wsi timeout, and
+is typically only reset by the sequencer callback when it receives an
+event indicating a step completed or failed, or it sets up the next sequence
+step.
+
+If the sequencer timeout expires, then the sequencer receives a queued
+`LWSSEQ_TIMED_OUT` message informing it, and it can take corrective action
+or schedule a retry of the step. This message is queued and sent normally
+under the service thread context and in order of receipt.
+
+Unlike lws timeouts which force the wsi to close, the sequencer timeout
+only sends the message. This allows the timeout to be used to, eg, wait
+out a retry cooloff period and then start the retry when the
+`LWSSEQ_TIMED_OUT` is received, according to the state of the sequencer.
+
+## Creating an `lws_sequencer_t`
+
+```
+typedef struct lws_seq_info {
+ struct lws_context *context; /* lws_context for seq */
+ int tsi; /* thread service idx */
+ size_t user_size; /* size of user alloc */
+ void **puser; /* place ptr to user */
+ lws_seq_event_cb cb; /* seq callback */
+ const char *name; /* seq name */
+ const lws_retry_bo_t *retry; /* retry policy */
+} lws_seq_info_t;
+```
+
+```
+lws_sequencer_t *
+lws_sequencer_create(lws_seq_info_t *info);
+```
+
+When created, in lws the sequencer objects are bound to a 'per-thread',
+which is by default the same as to say bound to the `lws_context`. You
+can tag them with an opaque user data pointer, and they are also bound to
+a user-specified callback which handles sequencer events
+
+```
+typedef int (*lws_seq_event_cb)(struct lws_sequencer *seq, void *user_data,
+ lws_seq_events_t event, void *data);
+```
+
+`lws_sequencer_t` objects are private to lws and opaque to the user. A small
+set of apis lets you perform operations on the pointer returned by the
+create api.
+
+## Queueing events on a sequencer
+
+Each sequencer object can be passed "events", which are held on a per-sequencer
+queue and handled strictly in the order they arrived on subsequent event loops.
+`LWSSEQ_CREATED` and `LWSSEQ_DESTROYED` events are produced by lws reflecting
+the sequencer's lifecycle, but otherwise the event indexes have a user-defined
+meaning and are queued on the sequencer by user code for eventual consumption
+by user code in the sequencer callback.
+
+Pending events are removed from the sequencer queues and sent to the sequencer
+callback from inside the event loop at a rate of one per event loop wait.
+
+## Destroying sequencers
+
+`lws_sequencer_t` objects are cleaned up during context destruction if they are
+still around.
+
+Normally the sequencer callback receives a queued message that
+informs it that it's either failed at the current step, or succeeded and that
+was the last step, and requests that it should be destroyed by returning
+`LWSSEQ_RET_DESTROY` from the sequencer callback.
+
+## Lifecycle considerations
+
+Sequencers may spawn additional assets like client wsi as part of the sequenced
+actions... the lifecycle of the sequencer and the assets overlap but do not
+necessarily depend on each other... that is a wsi created by the sequencer may
+outlive the sequencer.
+
+It's important therefore to detach assets from the sequencer and the sequencer
+from the assets when each step is over and the asset is "out of scope" for the
+sequencer. It doesn't necessarily mean closing the assets, just making sure
+pointers are invalidated. For example, if a client wsi held a pointer to the
+sequencer as its `.user_data`, when the wsi is out of scope for the sequencer
+it can set it to NULL, eg, `lws_set_wsi_user(wsi, NULL);`.
+
+Under some conditions wsi may want to hang around a bit to see if there is a
+subsequent client wsi transaction they can be reused on. They will clean
+themselves up when they time out.
+
+## Watching wsi lifecycle from a sequencer
+
+When a sequencer is creating a wsi as part of its sequence, it will be very
+interested in lifecycle events. At client wsi creation time, the sequencer
+callback can set info->seq to itself in order to receive lifecycle messages
+about its wsi.
+
+|message|meaning|
+|---|---|
+|`LWSSEQ_WSI_CONNECTED`|The wsi has become connected|
+|`LWSSEQ_WSI_CONN_FAIL`|The wsi has failed to connect|
+|`LWSSEQ_WSI_CONN_CLOSE`|The wsi had been connected, but has now closed|
+
+By receiving these, the sequencer can understand when it should attempt
+reconnections or that it cannot progress the sequence.
+
+When dealing with wsi that were created by the sequencer, they may close at
+any time, eg, be closed by the remote peer or an intermediary. The
+`LWSSEQ_WSI_CONN_CLOSE` message may have been queued but since they are
+strictly handled in the order they arrived, before it was
+handled an earlier message may want to cause some api to be called on
+the now-free()-d wsi. To detect this situation safely, there is a
+sequencer api `lws_sequencer_check_wsi()` which peeks the message
+buffer and returns nonzero if it later contains an `LWSSEQ_WSI_CONN_CLOSE`
+already.

+lws_struct provides a lightweight method for serializing and deserializing C
+structs to and from JSON, and to and from sqlite3.
+
+
+
+ - you provide a metadata array describing struct members one-time, then call
+ generic apis to serialize and deserialize
+
+ - supports flat structs, single child struct pointers, and unbounded arrays /
+ linked-lists of child objects automatically using [lws_dll2 linked-lists](./README.lws_dll.md)
+
+ - supports boolean and C types char, int, long, long long in explicitly signed
+ and unsigned forms
+
+ - supports both char * type string members where the unbounded content is
+ separate and pointed to, and fixed length char array[] type members where
+ the content is part of the struct
+
+ - huge linear strings are supported by storing to a temp lwsac of chained chunks,
+ which is written into a single linear chunk in the main lwsac once the
+ total string length is known
+
+ - deserialization allocates into an [lwsac](../lib/misc/lwsac/README.md), so everything is inside as few
+ heap allocations as possible while still able to expand to handle arbitrary
+ array or strins sizes
+
+ - when deserialized structs are finished with, a single call to free the
+ lwsac frees the whole thing without having to walk it
+
+ - stateful serializaton and deserialization allows as-you-get packets incremental
+ parsing and production of chunks of as-you-can-send incremental serialization
+ output cleanly

+
+@section rawconf Configuring Fallback and Raw vhosts
+
+Lws supports some unusual modes for vhost listen sockets, which may be
+configured entirely using the JSON per-vhost config language in the related
+vhost configuration section.
+
+There are three main uses for them
+
+1) A vhost bound to a specific role and protocol, not http. This binds all
+incoming connections on the vhost listen socket to the "raw-proxy" role and
+protocol "myprotocol".
+
+```
+ "listen-accept-role": "raw-proxy",
+ "listen-accept-protocol": "myprotocol",
+ "apply-listen-accept": "1"
+```
+
+2) A vhost that wants to treat noncompliant connections for http or https as
+ belonging to a secondary fallback role and protocol. This causes non-https
+ connections to an https listener to stop being treated as https, to lose the
+ tls wrapper, and bind to role "raw-proxy" and protocol "myprotocol". For
+ example, connect a browser on your external IP :443 as usual and it serves
+ as normal, but if you have configured the raw-proxy to portforward
+ 127.0.0.1:22, then connecting your ssh client to your external port 443 will
+ instead proxy your sshd over :443 with no http or tls getting in the way.
+
+```
+ "listen-accept-role": "raw-proxy",
+ "listen-accept-protocol": "myprotocol",
+ "fallback-listen-accept": "1",
+ "allow-non-tls": "1"
+```
+
+3) A vhost wants to either redirect stray http traffic back to https, or to
+ actually serve http on an https listen socket (this is not recommended
+ since it allows anyone to drop the security assurances of https by
+ accident or design).
+
+```
+ "allow-non-tls": "1",
+ "redirect-http": "1",
+```
+
+...or,
+
+```
+ "allow-non-tls": "1",
+ "allow-http-on-https": "1",
+```
@section lwswspl Lwsws Plugins
sudo mkdir /var/log/lwsws
sudo chmod 700 /var/log/lwsws

+
+@section lwswsgdb Debugging lwsws with gdb
+
+Hopefully you won't need to debug lwsws itself, but you may want to debug your plugins. start lwsws like this to have everything running under gdb
+
+```
+sudo gdb -ex "set follow-fork-mode child" -ex "run" --args /usr/local/bin/lwsws
+
+```
+
+this will give nice backtraces in lwsws itself and in plugins, if they were built with symbols.
+
+@section lwswsvgd Running lwsws under valgrind
+
+You can just run lwsws under valgrind as usual and get valid results. However the results / analysis part of valgrind runs
+after the plugins have removed themselves, this means valgrind backtraces into plugin code is opaque, without
+source-level info because the dynamic library is gone.
+
+There's a simple workaround, use LD_PRELOAD=<plugin.so> before running lwsws, this has the loader bring the plugin
+in before executing lwsws as if it was a direct dependency. That means it's still mapped until the whole process
+exits after valgtind has done its thing.

+lws-acme-client Plugin
+======================
+
+## Introduction
+
+lws-acme-client is a protcol plugin for libwebsockets that implements an
+ACME client able to communicate with let's encrypt and other certificate
+providers.
+
+It implements `tls-sni-01` challenge, and is able to provision tls certificates
+"from thin air" that are accepted by all the major browsers. It also manages
+re-requesting the certificate when it only has two weeks left to run.
+
+It works with both the OpenSSL and mbedTLS backends.
+
+## Overview for use
+
+You need to:
+
+ - Provide name resolution to the IP with your server, ie, myserver.com needs to
+ resolve to the IP that hosts your server
+
+ - Enable port forwarding / external firewall access to your port, usually 443
+
+ - Enable the "lws-acme-client" plugin on the vhosts you want it to manage
+ certs for
+
+ - Add per-vhost options describing what should be in the certificate
+
+After that the plugin will sort everything else out.
+
+## Example lwsws setup
+
+```
+ "vhosts": [ {
+ "name": "home.warmcat.com",
+ "port": "443",
+ "host-ssl-cert": "/etc/lwsws/acme/home.warmcat.com.crt.pem",
+ "host-ssl-key": "/etc/lwsws/acme/home.warmcat.com.key.pem",
+ "ignore-missing-cert": "1",
+ "access-log": "/var/log/lwsws/test-access-log",
+ "ws-protocols": [{
+ "lws-acme-client": {
+ "auth-path": "/etc/lwsws/acme/auth.jwk",
+ "cert-path": "/etc/lwsws/acme/home.warmcat.com.crt.pem",
+ "key-path": "/etc/lwsws/acme/home.warmcat.com.key.pem",
+ "directory-url": "https://acme-staging.api.letsencrypt.org/directory",
+ "country": "TW",
+ "state": "Taipei",
+ "locality": "Xiaobitan",
+ "organization": "Crash Barrier Ltd",
+ "common-name": "home.warmcat.com",
+ "email": "andy@warmcat.com"
+ },
+ ...
+```
+
+## Required PVOs
+
+Notice that the `"host-ssl-cert"` and `"host-ssl-key"` entries have the same
+meaning as usual, they point to your certificate and private key. However
+because the ACME plugin can provision these, you should also mark the vhost with
+`"ignore-missing-cert" : "1"`, so lwsws will ignore what will initially be
+missing certificate / keys on that vhost, and will set about creating the
+necessary certs and keys instead of erroring out.
+
+You must make sure the directories mentioned here exist, lws doesn't create them
+for you. They should be 0700 root:root, even if you drop lws privileges.
+
+If you are implementing support in code, this corresponds to making sure the
+vhost creating `info.options` has the `LWS_SERVER_OPTION_IGNORE_MISSING_CERT`
+bit set.
+
+Similarly, in code, the each of the per-vhost options shown above can be
+provided in a linked-list of structs at vhost creation time. See
+`./test-apps/test-server-v2.0.c` for example code for providing pvos.
+
+### auth-path
+
+This is where the plugin will store the auth keys it generated.
+
+### cert-path
+
+Where the plugin will store the certificate file. Should match `host-ssl-cert`
+that the vhost wants to use.
+
+The path should include at least one 0700 root:root directory.
+
+### key-path
+
+Where the plugin will store the certificate keys. Again it should match
+`host-ssl-key` the vhost is trying to use.
+
+The path should include at least one 0700 root:root directory.
+
+### directory-url
+
+This defines the URL of the certification server you will get your
+certificates from. For let's encrypt, they have a "practice" one
+
+ - `https://acme-staging.api.letsencrypt.org/directory`
+
+and they have a "real" one
+
+ - `https://acme-v01.api.letsencrypt.org/directory`
+
+the main difference is the CA certificate for the real one is in most browsers
+already, but the staging one's CA certificate isn't. The staging server will
+also let you abuse it more in terms of repeated testing etc.
+
+It's recommended you confirm expected operation with the staging directory-url,
+and then switch to the "real" URL.
+
+### common-name
+
+Your server DNS name, like "libwebsockets.org". The remote ACME server will
+use this to find your server to perform the SNI challenges.
+
+### email
+
+The contact email address for the certificate.
+
+## Optional PVOs
+
+These are not included in the cert by letsencrypt
+
+### country
+
+Two-letter country code for the certificate
+
+### state
+
+State "or province" for the certificate
+
+### locality
+
+Locality for the certificate
+
+### organization
+
+Your company name
+
+## Security / Key storage considerations
+
+The `lws-acme-client` plugin is able to provision and update your certificate
+and keys in an entirely root-only storage environment, even though lws runs
+as a different uid / gid with no privileges to access the storage dir.
+
+It does this by opening and holding two WRONLY fds on "update paths" inside the
+root directory structure for each cert and key it manages; these are the normal
+cert and key paths with `.upd` appended. If during the time the server is up
+the certs become within two weeks of expiry, the `lws-acme-client` plugin will
+negotiate new certs and write them to the file descriptors.
+
+Next time the server starts, if it sees `.upd` cert and keys, it will back up
+the old ones and copy them into place as the new ones, before dropping privs.
+
+To also handle the long-uptime server case, lws will update the vhost with the
+new certs using in-memory temporary copies of the cert and key after updating
+the cert.
+
+In this way the cert and key live in root-only storage but the vhost is kept up
+to date dynamically with any cert changes as well.
+
+## Multiple vhosts using same cert
+
+In the case you have multiple vhosts using of the same cert, just attach
+the `lws-acme-client` plugin to one instance. When the cert updates, all the
+vhosts are informed and vhosts using the same filepath to access the cert will
+be able to update their cert.
+
+## Implementation point
+
+You will need to remove the auth keys when switching from OpenSSL to
+mbedTLS. They will be regenerated automatically. It's the file at this
+path:
+
+```
+"auth-path": "/etc/lwsws/acme/auth.jwk",
+```
--- /dev/null
+ssh-base Plugin
+================
+
+## Introduction
+
+lws-ssh-base is a protcol plugin for libwebsockets that implements a
+generic, abstract, ssh server.
+
+ - very small footprint in code and memory, takes up small part of ESP32
+
+ - written with security in mind: valgrind and Coverity -clean
+
+ - binds to one or more vhosts, that controls listen port(s)
+
+ - all IO and settings abstracted through a single "ops" struct from user code
+
+ - each instance on a vhost has its own "ops" struct, defining server keys,
+ auth method and functions to implement IO and other operations
+
+ - The plugin has no built-in behaviours like check ~/.ssh/authorized_keys,
+ treat auth usernames as system usernames, or spawn the user's shell.
+ Everything potentially dangerous is left to the user ops code to decide
+ how to handle. It's NOT like sshd where running it implies it will accept
+ existing keys for any system user, will spawn a shell, etc, unless you
+ implement those parts in the ops callbacks.
+
+ - The plugin requires extra code around it in the form of the ops struct
+ handlers. So it's role is something like an abstract base class for an ssh
+ server. All the crypto, protocol sequencing and state machine are inside,
+ but all the IO except the network connection is outside.
+
+ - Built as part of libwebsockets, like all plugins may be dynamically loaded
+ at runtime or built statically. Test app `libwebsockets-test-sshd` provided
+
+ - Uses hash and RSA functions from either mbedTLS or OpenSSL automatically,
+ according to which library libwebsockets was built for
+
+To maintain its small size, it implements a single "best of breed" crypto for
+the following functions:
+
+|Function|Crypto|
+|---|---|
+|KEX|curve25519-sha256@libssh.org|
+|Server host key|ssh-rsa (4096b)|
+|Encryption|chacha20-poly1305@openssh.com|
+|Compression|None|
+
+## License
+
+lws-ssh-base is Free Software, available under libwebsocket's LGPLv2 +
+static linking exception license.
+
+The crypto parts are available elsewhere under a BSD license. But for
+simplicity the whole plugin is under LGPLv2.
+
+## Generating your own keys
+
+```
+ $ ssh-keygen -t rsa -b 4096 -f mykeys
+```
+
+will ask for a passphrase and generate the private key in `mykeys` and the
+public key in `mykeys.pub`. If you already have a suitable RSA key you use
+with ssh, you can just use that directly.
+
+lws installs a test keypair in /usr[/local]/share/libwebsockets-test-server
+that the test apps will accept.
+
+## Example code
+
+1) There's a working example app `libwebsockets-test-sshd` included that
+spawns a bash shell when an ssh client authenticates. The username used on
+the remote ssh has no meaning, it spawns the shell under the credentials of
+"lws-test-sshd" was run under. It accepts the lws ssh test key which is
+installed into /usr[/local]/share/libwebsockets-test-server.
+
+Start the server like this (it wants root only because the server key is stored
+in /etc)
+
+```
+ $ sudo libwebsockets-test-sshd
+```
+
+Connect to it using the test private key like this
+
+```
+ $ ssh -p 2200 -i /usr/local/share/libwebsockets-test-server/lws-ssh-test-keys anyuser@127.0.0.1
+```
+
+2) There's also a working example plugin `lws-sshd-demo` that "subclasses" the
+abstract `lws-ssh-base` plugin to make a protocol which can be used from,
+eg, lwsws. For an lwsws vhost that listens on port 2222 and responds with
+the lws-sshd-demo ssh server, the related config is:
+
+```
+ {
+ "name": "sshd",
+ "port": "2222",
+ "onlyraw": "1",
+ "ws-protocols": [{
+ "lws-ssh-base": {
+ "status": "ok",
+ "ops-from": "lws-sshd-demo"
+ },
+ "lws-sshd-demo": {
+ "status": "ok",
+ "raw": "1"
+ }
+ }]
+ }
+```
+
+
+
+## Integration to other apps
+
+### Step 0: Build and install libwebsockets
+
+For the `libwebsockets-test-sshd` example, you will need CMake options
+`LWS_WITH_CGI`, since it uses lws helpers to spawn a shell.
+
+lws-ssh-base itself doesn't require CGI support in libwebsockets.
+
+### Step 1: make the code available in your app
+
+Include `lws-plugin-ssh-base` in your app, either as a runtime plugin or by using
+the lws static include scheme.
+
+To bring in the whole of the ssh-base plugin
+into your app in one step, statically, just include
+`plugins/ssh-base/include/lws-plugin-sshd-static-build-includes.h`, you can see
+an example of this in `./test-apps/test-sshd.c`.
+
+### Step 2: define your `struct lws_ssh_ops`
+
+`plugins/ssh-base/include/lws-plugin-ssh.h` defines
+`struct lws_ssh_ops` which is used for all customization and integration
+of the plugin per vhost. Eg,
+
+```
+static const struct lws_ssh_ops ssh_ops = {
+ .channel_create = ssh_ops_channel_create,
+ .channel_destroy = ssh_ops_channel_destroy,
+ .tx_waiting = ssh_ops_tx_waiting,
+ .tx = ssh_ops_tx,
+ .rx = ssh_ops_rx,
+ .get_server_key = ssh_ops_get_server_key,
+ .set_server_key = ssh_ops_set_server_key,
+ .set_env = ssh_ops_set_env,
+ .pty_req = ssh_ops_pty_req,
+ .child_process_io = ssh_ops_child_process_io,
+ .child_process_terminated = ssh_ops_child_process_terminated,
+ .exec = ssh_ops_exec,
+ .shell = ssh_ops_shell,
+ .is_pubkey_authorized = ssh_ops_is_pubkey_authorized,
+ .banner = ssh_ops_banner,
+ .disconnect_reason = ssh_ops_disconnect_reason,
+ .server_string = "SSH-2.0-Libwebsockets",
+ .api_version = 1,
+};
+```
+The `ssh_ops_...()` functions are your implementations for the operations
+needed by the plugin for your purposes.
+
+### Step 3: enable `lws-ssh-base` protocol to a vhost and configure using pvo
+
+A pointer to your struct lws_ssh_ops is passed into the vhost instance of the
+protocol using per-vhost options
+
+```
+static const struct lws_protocol_vhost_options pvo_ssh_ops = {
+ NULL,
+ NULL,
+ "ops",
+ (void *)&ssh_ops
+};
+
+static const struct lws_protocol_vhost_options pvo_ssh = {
+ NULL,
+ &pvo_ssh_ops,
+ "lws-sshd-base",
+ "" /* ignored, just matches the protocol name above */
+};
+
+...
+ info.port = 22;
+ info.options = LWS_SERVER_OPTION_ONLY_RAW;
+ info.vhost_name = "sshd";
+ info.protocols = protocols_sshd;
+ info.pvo = &pvo_ssh;
+
+ vh_sshd = lws_create_vhost(context, &info);
+```
+
+There are two possible pvos supported, "ops", shown above, directly passes the
+ops structure in using the value on the "ops" pvo.
+
+To support other protocols that want to provide ops to lws-ssh-base themselves
+for a particular vhost, you can also provide a pvo `"ops-from"` whose value is
+the name of the protocol also enabled on this vhost, whose protocol ".user"
+pointer points to the ops struct lws-ssh-base should use.
+
+## Integration to other plugins
+
+A worked example of using the abstract `lws-ssh-base` plugin from another
+plugin that provides the ops struct is in `./plugins/protocol_lws_sshd_demo`.
+
+The key points to note
+
+ - the plugin sets the ops struct for the vhost instantiation of `lws-ssh-base`
+ by passing a pointer to the ops struct in its `lws_protocols` struct `user`
+ member.
+
+ - the config for the vhost tells `lws-ssh-base` to pick up the ops struct
+ pointer using an "ops-from" pvo that indicates the protocol name.
+
+```
+ "lws-ssh-base": {
+ "status": "ok",
+ "ops-from": "lws-sshd-demo"
+ },
+```
+
+ - the config for the vhost tells lws this vhost only serves RAW (ie, no http)
+
+```
+ {
+ "name": "sshd",
+ "port": "2222",
+ "onlyraw": "1",
+ ...
+```
+
+ - the config for the vhost marks the protocol that uses `lws-ssh-base`, not
+ `lws-ssh-base` itself, as the protocol to be served for raw connections
+
+```
+ "lws-sshd-demo": {
+ "status": "ok",
+ "raw": "1"
+ ...
+```
+
+## Notes
+
+You can have the vhost it binds to listen on a nonstandard port. The ssh
+commandline app cane be told to connect to a non-22 port with
+`ssh -p portnum user@hostname`
+
+
--- /dev/null
+# Guidance for porting to new platform
+
+Where differences existed between the initial POSIX platform for lws and other
+supported platforms like Windows, `lws_plat_...()` apis were added to move
+handling to platform-specific code in `./lib/plat/`.
+
+Depending o which platform is built, different platform-specific implementations
+of these `lws_plat...()` apis get built.
+
+## 1) Prepare the cmake cross-build file if necessary
+
+CMake isolates its settings for cross-build into a separate file, which can be
+used to different cmake projects for the same platform as well.
+
+Find a similar examples already in `./contrib/cross-*` and copy and adapt it
+as needed,
+
+All settings related to toolchain should go in there. For cross-toolchain,
+the convention is to pass the path to its installed directory in `CROSS_PATH`
+environment variable.
+
+## 2) Copy the closest platform dir in ./lib/plat
+
+Wholesale copy the closest existing platform dir to `/lib/plat/myplatform` and
+rename the files.
+
+Remove stuff specific to the original platform.
+
+## 3) Add a flag in CMakeLists.txt
+
+Cut and paste a flag to select your platform, preferably `LWS_PLAT_MYPLATFORM` or so
+
+## 4) Add a section to force-select and deselect other cmake options based on platform flag
+
+Some options on by default may not make sense on your platform, and others off
+by default may be mandatory. After the options() section in CMakeLists.txt, you
+can use this kind of structure
+
+```
+ if (LWS_PLAT_MYPLATFORM)
+ set(LWS_WITH_XXXX 0)
+ endif()
+```
+
+to enforce implicit requirements of your platform. Optional stuff should be set by
+running cmake commandline as usual.
+
+## 5) Add building your platform files into CMakeLists.txt
+
+Add entries in CMakeLists.txt for building stuff in `./lib/plat/myplatform` when
+`LWS_PLAT_MYPLATFORM` is enabled.
+
+## 6) Adapt your copied ./lib/plat/myplatform/ files
+
+You can now do test builds using the cross-build file, your platform flag in
+cmake, and your copied ./lib/plat content... this last part since it was
+copied from another platform will initially be a plentiful source of errors.
+
+You can iteratively build and adapt the platform files.

+Debugging problems
+==================
+
+Check it's still a problem with latest lws
+------------------------------------------
+
+Older versions of lws don't attract any new work after they are released
+(see [the release policy](https://libwebsockets.org/git/libwebsockets/tree/READMEs/README.release-policy.md) for details);
+for a while they will get backported bugfixes but that's it.
+
+All new work and bugfixes happen on master branch.
+
+Old, old versions may be convenient for you to use for some reason. But unless
+you pay for support or have contributed work to lws so we feel we owe you some
+consideration, nobody else has any reason to particularly care about solving
+issues on ancient versions. Whereas if the problem exists on master, and can be
+reproduced by developers, it usually gets attention, often immediately.
+
+If the problem doesn't exist on master, you can either use master or check also
+the -stable branch of the last released version to see if it was already solved
+there.
+
+Library is a component
+----------------------
+
+As a library, lws is always just a component in a bigger application.
+
+When users have a problem involving lws, what is happening in the bigger
+application is usually critical to understand what is going on (and where the
+solution lies). Sometimes access to the remote peer like server or client is also
+necessary to provoke the symptom. Sometimes, the problem is in lws, but
+sometimes the problem is not in lws but in these other pieces.
+
+Many users are able to share their sources, but others decide not to, for
+presumed "commercial advantage" or whatever. (In any event, it can be painful
+looking through large chunks of someone else's sources for problems when that
+is not the library author's responsibility.)
+
+This makes answering questions like "what is wrong with my code I am not
+going to show you?" or even "what is wrong with my code?" very difficult.
+
+Even if it's clear there is a problem somewhere, it cannot be understood or
+reproduced by anyone else if it needs user code that isn't provided.
+
+The biggest question is, "is this an lws problem actually"? To solve that
+the best solution is to strip out all or as much user code as possible,
+and see if the problem is still coming.
+
+
+Use the test apps / minimal examples as sanity checks
+-----------------------------------------------------
+
+The test server and client, and any more specifically relevant minimal example
+ are extremely useful for sanity checks and debugging guidance.
+
+ - **test apps work on your platform**, then either
+ - your user code is broken, align it to how the test apps work, or,
+ - something from your code is required to show an lws problem, provide a
+ minimal patch on a test app so it can be reproduced
+
+ - **test apps break on your platform**, but work on, eg, x86_64, either
+ - toolchain or platform-specific (eg, OS) issue, or
+ - lws platform support issue
+
+ - **test apps break everywhere**
+ - sounds like lws problem, info to reproduce and / or a patch is appreciated

+# lws release policy
+
+## Master branch
+
+Master branch is the default and all new work happens there. It's unstable and
+subject to history rewrites, patches moving about and being squashed etc. In
+terms of it working, it is subject to passing CI tests including a battery of
+runtime tests, so if it is passing CI as it usually is then it's probably in
+usable shape.
+
+
+
+If you have patches (you are a hero) they should be targeted at master.
+
+To follow such a branch, `git pull` is the wrong tool... the starting point
+of what you currently have may no longer exist remotely due to rearranging the
+patches there. Instead use a flow like this:
+
+```
+ $ git fetch https://libwebsockets.org/repo/libwebsockets +master:m && git reset --hard m
+```
+
+This fetches current remote master into local branch `m`, and then forces your
+local checkout to exactly match `m`. This replaces your checked-out tree
+including any of your local changes, so stash those first, or use stgit or so
+to pop them before updating your basis against lws master.
+
+## Stable branches
+
+Master is very useful for coordinating development, and integrating WIP,
+but for distros or integration into large user projects some stability is often
+more desirable than the latest development work.
+
+Periodically, when master seems in good shape and various new developments seem
+to be working, it's copied out into a versioned stable branch, like `v3.0-stable`.
+
+
+
+The initial copy is tagged with, eg, `v3.0.0`.
+
+(At that time, master's logical version is set to "...99", eg, `v3.0.99` so
+version comparisons show that version of master is "later" than any other
+v3.0 version, which will never reach 99 point releases itself, but "earlier"
+than, eg, v3.1.)
+
+## Backport policy
+
+Work continues on master, and as part of that usually bugs are reported and / or
+fixes found that may apply not just to current master, but the version of master
+that was copied to form the last -stable branch.
+
+In that case, the patch may be backported to the last stable branch to also fix
+the bug there. In the case of refactors or major internal improvements, these
+typically do not get backported.
+
+This applies only to fixes and public API-neutral internal changes to lws... if
+new features were backported or API changes allowed, then there would be
+multiple apis under the same version name and library soname, which is
+madness.
+
+When new stable releases are made, the soname is bumped reflecting the API is
+different than that of previous versions.
+
+
+
+If there is something you need in a later lws version that is not backported,
+you need to either backport it yourself (remember that lws is LGPL and you must
+provide your changes when you distribute the binary) or use a later lws version.
+Using a more recent version of lws is almost always the correct way.
+
+## Stable point releases
+
+Periodically fix patches pile up on the -stable branch and are tagged out as
+"point releases". So if the original stable release was "v3.0.0", the point
+release may be "v3.0.1".
+
+
+
+## Critical fixes
+
+Sometimes a bug is found and fixed that had been hiding for a few versions.
+If the bug has some security dimension or is otherwise important, we may
+backport it to a few recent releases, not just the last one. This is pretty
+uncommon though.

preferability.

+See [README.lwsws.md](../READMEs/README.lwsws.md) for information on how to configure
lwsws.
NOTE this method implies libuv is used by lws, to provide crossplatform
This method lets you configure web serving in code, instead of using lwsws.
-Plugins are still used, which implies libuv needed.
+Plugins are still used, but you have a choice whether to dynamically load
+them or statically include them. In this example, they are dynamically
+loaded.

-See [test-server-v2.0.c](test-server/test-server-v2.0.c)
+See [test-server-v2.0.c](../test-apps/test-server-v2.0.c)
3) protocols in the server app
This method is still supported in lws but all ongoing and future work is
being done in protocol plugins only.
+You can simply include the plugin contents and have it buit statically into
+your server, just define this before including the plugin source
+
+```
+#define LWS_PLUGIN_STATIC
+```
+
+This gets you most of the advantages without needing dynamic loading +
+libuv.

(eg, Chrome) to

To stop the daemon, do
```
- $ kill cat /tmp/.lwsts-lock
+ $ kill \`cat /tmp/.lwsts-lock\`
```
If it finds a stale lock (the pid mentioned in the file does not exist
any more) it will delete the lock and create a new one during startup.
If the lock is valid, the daemon will exit with a note on stderr that
it was already running.
+@section clicert Testing Client Certs
+
+Here is a very quick way to create a CA, and a client and server cert from it,
+for testing.
+
+```
+$ cp -rp ./scripts/client-ca /tmp
+$ cd /tmp/client-ca
+$ ./create-ca.sh
+$ ./create-server-cert.sh server
+$ ./create-client-cert.sh client
+```
+
+The last step wants an export password, you will need this password again to
+import the p12 format certificate into your browser.
+
+This will get you the following
+
+|name|function|
+|----|--------|
+|ca.pem|Your Certificate Authority cert|
+|ca.key|Private key for the CA cert|
+|client.pem|Client certificate, signed by your CA|
+|client.key|Client private key|
+|client.p12|combined client.pem + client.key in p12 format for browsers|
+|server.pem|Server cert, signed by your CA|
+|server.key|Server private key|
+
+You can confirm yourself the client and server certs are signed by the CA.
+
+```
+ $ openssl verify -verbose -trusted ca.pem server.pem
+ $ openssl verify -verbose -trusted ca.pem client.pem
+```
+
+Import the client.p12 file into your browser. In FFOX57 it's
+
+ - preferences
+ - Privacy & Security
+ - Certificates | View Certificates
+ - Certificate Manager | Your Certificates | Import...
+ - Enter the password you gave when creating client1.p12
+ - Click OK.
+
+You can then run the test server like this:
+
+```
+ $ libwebsockets-test-server -s -A ca.pem -K server.key -C server.pem -v
+```
+
+When you connect your browser to https://localhost:7681 after accepting the
+selfsigned server cert, your browser will pop up a prompt to send the server
+your client cert (the -v switch enables this). The server will only accept
+a client cert that has been signed by ca.pem.

+## Unix Domain Sockets Reverse Proxy
+
+### Introduction
+
+lws is able to use a mount to place reverse proxies into the URL space.
+
+These are particularly useful when using Unix Domain Sockets, basically
+files in the server filesystem, to communicate between lws and a separate
+server process and integrate the result into a coherent URL namespace on
+the lws side. It's also possible to proxy using tcp sockets.
+
+
+
+This has the advantage that the actual web server that forwards the
+data from the unix socket owner is in a different process than the server
+that serves on the unix socket. If it has problems, they do not affect
+the actual public-facing web server. The unix domain socket server may
+be in a completely different language than the web server.
+
+Compared to CGI, there are no forks to make a connection to the unix
+domain socket server.
+
+### Mount origin format
+
+Unix Domain Sockets are effectively "files" in the server filesystem, and
+are defined by their filepath. The "server" side that is to be proxied opens
+the socket and listens on it, which creates a file in the server filesystem.
+The socket understands either http or https protocol.
+
+Lws can be told to act as a proxy for that at a mountpoint in the lws vhost
+url space.
+
+If your mount is expressed in C code, then the mount type is LWSMPRO_HTTP or
+LWSMPRO_HTTPS depending on the protocol the unix socket understands, and the
+origin address has the form `+/path/to/unix/socket:/path/inside/mount`.
+
+The + at the start indicates it is a local unix socket we are proxying, and
+the ':' acts as a delimiter for the socket path, since unlike other addresses
+the unix socket path can contain '/' itself.
+
+### Connectivity rules and translations
+
+Onward proxy connections from lws to the Unix Domain Socket happen using
+http/1.1. That implies `transfer-encoding: chunking` in the case that the
+length of the output is not known beforehand.
+
+Lws takes care of stripping any chunking (which is illegal in h2) and
+translating between h1 and h2 header formats if the return connection is
+actually in http/2.
+
+The h1 onward proxy connection translates the following headers from the return
+connection, which may be h1 or h2:
+
+Header|Function
+---|---
+host|Which vhost
+etag|Information on any etag the client has cached for this URI
+if-modified-since|Information on the freshness of any etag the client has cached for this URI
+accept-language|Which languages the return path client prefers
+accept-encoding|Which compression encodings the client can accept
+cache-control|Information from the return path client about cache acceptability
+x-forwarded-for|The IP address of the return path client
+
+This implies that the proxied connection can
+
+ - return 301 etc to say the return path client's etag is still valid
+
+ - choose to compress using an acceptable content-encoding
+
+The following headers are translated from the headers replied via the onward
+connection (always h1) back to the return path (which may be h1 or h2)
+
+Header|Function
+---|---
+content-length|If present, an assertion of how much payload is expected
+content-type|The mimetype of the payload
+etag|The canonical etag for the content at this URI
+accept-language|This is returned to the return path client because there is no easy way for the return path client to know what it sent originally. It allows clientside selection of i18n.
+content-encoding|Any compression format on the payload (selected from what the client sent in accept-encoding, if anything)
+cache-control|The onward server's response about cacheability of its payload
+
+### h1 -> h2 conversion
+
+Chunked encoding that may have been used on the outgoing proxy client connection
+is removed for h2 return connections (chunked encoding is illegal for h2).
+
+Headers are converted to all lower-case and hpack format for h2 return connections.
+
+Header and payload proxying is staged according to when the return connection
+(which may be an h2 child stream) is writable.
+
+### Behaviour if unix domain socket server unavailable
+
+If the server that listens on the unix domain socket is down or being restarted,
+lws understands that it couldn't connect to it and returns a clean 503 response
+`HTTP_STATUS_SERVICE_UNAVAILABLE` along with a brief human-readable explanation.
+
+The generated status page produced will try to bring in a stylesheet
+`/error.css`. This allows you to produce a styled error pages with logos,
+graphics etc. See [this](https://libwebsockets.org/git/badrepo) for an example of what you can do with it.

Changelog
---------
+v3.2.0
+======
+
+ - This is the last planned release under LGPLv2+SLE. It's not planned to be
+ maintained like previous releases, please switch to master for the latest
+ stuff or continue to use v3.1-stable until the next release under the
+ new MIT license.
+
+ - NEW: completely refactored scheduler with a unified, sorted us-resolution
+ linked-list implementation. All polled checks like timeout are migrated
+ to use the new timers, which also work on the event lib implementations.
+ Faster operation, us-resolution timeouts and generic scheduled callbacks
+ from the event loop.
+
+ - NEW: lws_dsh specialized buffer memory allocator that can borrow space
+ from other cooperating buffers on the same list.
+
+ - NEW: lws_sequencer allows managing multi-connection processes and
+ retries
+
+ - NEW: memory buffer cert support
+
+ - NEW: LWS_WITH_NETWORK in CMake... can be configured without any network-
+ related code at all
+
+ - NEW: builds on QNX 6.5 and SmartOS
+
+ - NEW: JOSE / JWK / JWS / JWE support, for all common ciphers and algs,
+ works on OpenSSL and mbedtls backends
+
+ - NEW: gencrypto now has genaes and genec in addition to genrsa, works
+ on OpenSSL and mbedtls backends
+
+ - NEW: raw_proxy role
+
+ - NEW: Basic Auth works on ws connections
+
+ - CHANGE: REMOVED: LWS_WITH_GENRSA, LWS_WITH_GENHASH, LWS_WITH_GENEC,
+ LWS_WITH_GENAES have all been removed and combined into LWS_WITH_GENCRYPTO
+
+ - CHANGE: REMOVED: LWS_WITH_JWS, LWS_WITH_JWE have been removed and combined
+ into LWS_WITH_JOSE
+
+v3.1.0
+======
+
+ - CHANGE: REMOVED: lws_client_connect() and lws_client_connect_extended()
+ compatibility apis for lws_client_connect_via_info() have been marked as
+ deprecated for several versions and are now removed. Use
+ lws_client_connect_via_info() directly instead.
+
+ - CHANGE: CMAKE:
+ - LWS_WITH_HTTP2: now defaults ON
+
+ - CHANGE: Minimal examples updated to use Content Security Policy best
+ practices, using
+ `LWS_SERVER_OPTION_HTTP_HEADERS_SECURITY_BEST_PRACTICES_ENFORCE` vhost
+ option flag and disabling of inline style and scripts. A side-effect of
+ this is that buffers used to marshal headers have to be prepared to take
+ more content than previously... LWS_RECOMMENDED_MIN_HEADER_SPACE (2048
+ currently) is available for user (and internal) use to logically tie the
+ buffer size to this usecase (and follow future increases).
+
+ - NEW: CMAKE
+ - LWS_FOR_GITOHASHI: sets various cmake options suitable for gitohashi
+ - LWS_WITH_ASAN: for Linux, enable build with ASAN
+
+ Don't forget LWS_WITH_DISTRO_RECOMMENDED, which enables a wide range of lws
+ options suitable for a distro build of the library.
+
+ - NEW: lws threadpool - lightweight pool of pthreads integrated to lws wsi, with
+ all synchronization to event loop handled internally, queue for excess tasks
+ [threadpool docs](https://libwebsockets.org/git/libwebsockets/tree/lib/misc/threadpool)
+ [threadpool minimal example](https://libwebsockets.org/git/libwebsockets/tree/minimal-examples/ws-server/minimal-ws-server-threadpool)
+ Cmake config: `-DLWS_WITH_THREADPOOL=1`
+
+ - NEW: libdbus support integrated on lws event loop
+ [lws dbus docs](https://libwebsockets.org/git/libwebsockets/tree/lib/roles/dbus)
+ [lws dbus client minimal examples](https://libwebsockets.org/git/libwebsockets/tree/minimal-examples/dbus-client)
+ [lws dbus server minimal examples](https://libwebsockets.org/git/libwebsockets/tree/minimal-examples/dbus-server)
+ Cmake config: `-DLWS_ROLE_DBUS=1`
+
+ - NEW: lws allocated chunks (lwsac) - helpers for optimized mass allocation of small
+ objects inside a few larger malloc chunks... if you need to allocate a lot of
+ inter-related structs for a limited time, this removes per-struct allocation
+ library overhead completely and removes the need for any destruction handling
+ [lwsac docs](https://libwebsockets.org/git/libwebsockets/tree/lib/misc/lwsac)
+ [lwsac minimal example](https://libwebsockets.org/git/libwebsockets/tree/minimal-examples/api-tests/api-test-lwsac)
+ Cmake Config: `-DLWS_WITH_LWSAC=1`
+
+ - NEW: lws tokenizer - helper api for robustly tokenizing your own strings without
+ allocating or adding complexity. Configurable by flags for common delimiter
+ sets and comma-separated-lists in the tokenizer. Detects and reports syntax
+ errors.
+ [lws_tokenize docs](https://libwebsockets.org/git/libwebsockets/tree/include/libwebsockets/lws-tokenize.h)
+ [lws_tokenize minimal example / api test](https://libwebsockets.org/git/libwebsockets/tree/minimal-examples/api-tests/api-test-lws_tokenize)
+
+ - NEW: lws full-text search - optimized trie generation, serialization,
+ autocomplete suggestion generation and instant global search support extensible
+ to huge corpuses of UTF-8 text while remaining super lightweight on resources.
+ [full-text search docs](https://libwebsockets.org/git/libwebsockets/tree/lib/misc/fts)
+ [full-text search minimal example / api test](https://libwebsockets.org/git/libwebsockets/tree/minimal-examples/api-tests/api-test-fts)
+ [demo](https://libwebsockets.org/ftsdemo/)
+ [demo sources](https://libwebsockets.org/git/libwebsockets/tree/plugins/protocol_fulltext_demo.c)
+ Cmake config: `-DLWS_WITH_FTS=1 -DLWS_WITH_LWSAC=1`
+
+ - NEW: gzip + brotli http server-side compression - h1 and h2 automatic advertising
+ of server compression and application to files with mimetypes "text/*",
+ "application/javascript" and "image/svg.xml".
+ Cmake config: `-DLWS_WITH_HTTP_STREAM_COMPRESSION=1`, `-DLWS_WITH_HTTP_BROTLI=1`
+
+ - NEW: managed disk cache - API for managing a directory containing cached files
+ with hashed names, and automatic deletion of LRU files once the cache is
+ above a given limit.
+ [lws diskcache docs](https://libwebsockets.org/git/libwebsockets/tree/include/libwebsockets/lws-diskcache.h)
+ Cmake config: `-DLWS_WITH_DISKCACHE=1`
+
+ - NEW: http reverse proxy - lws mounts support proxying h1 or h2 requests to
+ a local or remote IP, or unix domain socket over h1. This allows microservice
+ type architectures where parts of the common URL space are actually handled
+ by external processes which may be remote or on the same machine.
+ [lws gitohashi serving](https://libwebsockets.org/git/) is handled this way.
+ CMake config: `-DLWS_WITH_HTTP_PROXY=1`
+
+ - NEW: lws_buflist - internally several types of ad-hoc malloc'd buffer have
+ been replaced by a new, exported api `struct lws_buflist`. This allows
+ multiple buffers to be chained and drawn down in strict FIFO order.
+
+ - NEW: In the case of h1 upgrade, the connection header is checked to contain
+ "upgrade". The vhost flag LWS_SERVER_OPTION_VHOST_UPG_STRICT_HOST_CHECK
+ also causes the Host: header to be confirmed to match the vhost name and
+ listen port.
+
+ - NEW: If no 404 redirect for `lws_return_http_status()` is specified for the vhost,
+ the status page produced will try to bring in a stylesheet `/error.css`. This allows
+ you to produce styled 404 or other error pages with logos, graphics etc. See
+ https://libwebsockets.org/git/badrepo for an example of what you can do with it.
+
+v3.0.0
+======
+
+ - CHANGE: Clients used to call LWS_CALLBACK_CLOSED same as servers...
+ LWS_CALLBACK_CLIENT_CLOSED has been introduced and is called for clients
+ now.
+
+ - CHANGE: LWS_CALLBACK_CLIENT_CONNECTION_ERROR used to only be directed at
+ protocols[0]. However in many cases, the protocol to bind to was provided
+ at client connection info time and the wsi bound accordingly. In those
+ cases, CONNECTION_ERROR is directed at the bound protocol, not protcols[0]
+ any more.
+
+ - CHANGE: CMAKE: the following cmake defaults have changed with this version:
+
+ - LWS_WITH_ZIP_FOPS: now defaults OFF
+ - LWS_WITH_RANGES: now defaults OFF
+ - LWS_WITH_ZLIB: now defaults OFF
+ - LWS_WITHOUT_EXTENSIONS: now defaults ON
+
+ - CHANGE: REMOVED: lws_alloc_vfs_file() (read a file to malloc buffer)
+
+ - CHANGE: REMOVED: lws_read() (no longer useful outside of lws internals)
+
+ - CHANGE: REMOVED: ESP8266... ESP32 is now within the same price range and much
+ more performant
+
+ - CHANGE: soname bump... don't forget to `ldconfig`
+
+ - NEW: all event libraries support "foreign" loop integration where lws itself
+ if just a temporary user of the loop unrelated to the actual loop lifecycle.
+
+ See `minimal-http-server-eventlib-foreign` for example code demonstrating
+ this for all the event libraries.
+
+ Internal loop in lws is also supported and demonstrated by
+ `minimal-http-server-eventlib`.
+
+ - NEW: ws-over-h2 support. This is a new RFC-on-the-way supported by Chrome
+ and shortly firefox that allows ws connections to be multiplexed back to the
+ server on the same tcp + tls wrapper h2 connection that the html and scripts
+ came in on. This is hugely faster that discrete connections.
+
+ - NEW: UDP socket adoption and related event callbacks
+
+ - NEW: Multi-client connection binding, queuing and pipelining support.
+
+ Lws detects multiple client connections to the same server and port, and
+ optimizes how it handles them according to the server type and provided
+ flags. For http/1.0, all occur with individual parallel connections. For
+ http/1.1, you can enable keepalive pipelining, so the connections occur
+ sequentially on a single network connection. For http/2, they all occur
+ as parallel streams within a single h2 network connection.
+
+ See minimal-http-client-multi for example code.
+
+ - NEW: High resolution timer API for wsi, get a callback on your wsi with
+ LWS_CALLBACK_TIMER, set and reset the timer with lws_set_timer_usecs(wsi, us)
+ Actual resolution depends on event backend. Works with all backends, poll,
+ libuv, libevent, and libev.
+
+ - NEW: Protocols can arrange vhost-protocol instance specific callbacks with
+ second resolution using `lws_timed_callback_vh_protocol()`
+
+ - NEW: ACME client plugin for self-service TLS certificates
+
+ - NEW: RFC7517 JSON Web Keys RFC7638 JWK thumbprint, and RFC7515 JSON Web
+ signatures support
+
+ - NEW: lws_cancel_service() now provides a generic way to synchronize events
+ from other threads, which appear as a LWS_CALLBACK_EVENT_WAIT_CANCELLED
+ callback on all protocols. This is compatible with all the event libraries.
+
+ - NEW: support BSD poll() where changes to the poll wait while waiting are
+ undone.
+
+ - NEW: Introduce generic hash, hmac and RSA apis that operate the same
+ regardless of OpenSSL or mbedTLS tls backend
+
+ - NEW: Introduce X509 element query api that works the same regardless of
+ OpenSSL or mbedTLS tls backend
+
+ - NEW: Introduce over 30 "minimal examples" in ./minimal-examples... these
+ replace most of the old test servers
+
+ - test-echo -> minimal-ws-server-echo and minimal-ws-client-echo
+
+ - test-server-libuv / -libevent / -libev ->
+ minimal-https-server-eventlib / -eventlib-foreign / -eventlib-demos
+
+ - test-server-v2.0 -> folded into all the minimal servers
+
+ - test-server direct http serving -> minimal-http-server-dynamic
+
+ The minimal examples allow individual standalone build using their own
+ small CMakeLists.txt.
+
+ - NEW: lws now detects any back-to-back writes that did not go through the
+ event loop inbetween and reports them. This will flag any possibility of
+ failure rather than wait until the problem happens.
+
+ - NEW: CMake has LWS_WITH_DISTRO_RECOMMENDED to select features that are
+ appropriate for distros
+
+ - NEW: Optional vhost URL `error_document_404` if given causes a redirect there
+ instead of serve the default 404 page.
+
+ - NEW: lws_strncpy() wrapper guarantees NUL in copied string even if it was
+ truncated to fit.
+
+ - NEW: for client connections, local protocol binding name can be separated
+ from the ws subprotocol name if needed, using .local_protocol_name
+
+ - NEW: Automatic detection of time discontiguities
+
+ - NEW: Applies TCP_USER_TIMEOUT for Linux tcp keepalive where available
+
+ - QA: 1600 tests run on each commit in Travis CI, including almost all
+ Autobahn in client and server mode, various h2load tests, h2spec, attack.sh
+ the minimal example selftests and others.
+
+ - QA: fix small warnings introduced on gcc8.x (eg, Fedora 28)
+
+ - QA: Add most of -Wextra on gcc (-Wsign-compare, -Wignored-qualifiers,
+ -Wtype-limits, -Wuninitialized)
+
+ - QA: clean out warnings on windows
+
+ - QA: pass all 146 h2spec tests now on strict
+
+ - QA: introduce 35 selftests that operate different minimal examples against
+ each other and confirm the results.
+
+ - QA: LWS_WITH_MINIMAL_EXAMPLES allows mass build of all relevant minimal-
+ examples with the LWS build, for CI and to make all the example binaries
+ available from the lws build dir ./bin
+
+ - REFACTOR: the lws source directory layout in ./lib has been radically
+ improved, and there are now README.md files in selected subdirs with extra
+ documentation of interest to people working on lws itself.
+
+ - REFACTOR: pipelined transactions return to the event loop before starting the
+ next part.
+
+ - REFACTOR: TLS: replace all TLS library constants with generic LWS ones and
+ adapt all the TLS library code to translate to these common ones.
+
+ Isolated all the tls-related private stuff in `./lib/tls/private.h`, and all
+ the mbedTLS stuff in `./lib/tls/mbedtls` + openSSL stuff in
+ `./lib/tls/openssl`
+
+ - REFACTOR: the various kinds of wsi possible with lws have been extracted
+ from the main code and isolated into "roles" in `./lib/roles` which
+ communicate with the core code via an ops struct. Everything related to
+ ah is migrated to the http role.
+
+ wsi modes are eliminated and replaced by the ops pointer for the role the
+ wsi is performing. Generic states for wsi are available to control the
+ lifecycle using core code.
+
+ Adding new "roles" is now much easier with the changes and ops struct to
+ plug into.
+
+ - REFACTOR: reduce four different kinds of buffer management in lws into a
+ generic scatter-gather struct lws_buflist.
+
+ - REFACTOR: close notifications go through event loop
+
+
+v2.4.0
+======
+
+ - HTTP/2 server support is now mature and usable! LWS_WITH_HTTP2=1 enables it.
+ Uses ALPN to serve HTTP/2, HTTP/1 and ws[s] connections all from the same
+ listen port seamlessly. (Requires ALPN-capable OpenSSL 1.1 or mbedTLS).
+
+ - LWS_WITH_MBEDTLS=1 at CMake now builds and works against mbedTLS instead of
+ OpenSSL. Most things work identically, although on common targets where
+ OpenSSL has acceleration, mbedTLS is many times slower in operation. However
+ it is a lot smaller codewise.
+
+ - Generic hash apis introduced that work the same on mbedTLS or OpenSSL backend
+
+ - LWS_WITH_PEER_LIMITS tracks IPs across all vhosts and allows restrictions on
+ both the number of simultaneous connections and wsi in use for any single IP
+
+ - lws_ring apis provide a generic single- or multi-tail ringbuffer... mirror
+ protocol now uses this. Features include ring elements may be sized to fit
+ structs in the ringbuffer, callback when no tail any longer needs an element
+ and it can be deleted, and zerocopy options to write new members directly
+ into the ringbuffer, and use the ringbuffer element by address too.
+
+ - abstract ssh 2 server plugin included, with both plugin and standalone
+ demos provided. You can bind the plugin to a vhost and also serve full-
+ strength ssh from the vhost. IO from the ssh server is controlled by an
+ "ops" struct of callbacks for tx, rx, auth etc.
+
+ - Many fixes, cleanups, source refactors and other improvements.

+/*! \defgroup diskcache LWS disk cache
+ * ## Disk cache API
+ *
+ * Lws provides helper apis useful if you need a disk cache containing hashed
+ * files and need to delete files from it on an LRU basis to keep it below some
+ * size limit.
+ *
+ * The API `lws_diskcache_prepare()` deals with creating the cache dir and
+ * 256 subdirs, which are used according to the first two chars of the hex
+ * hash of the cache file.
+ *
+ * `lws_diskcache_create()` and `lws_diskcache_destroy()` allocate and free
+ * an opaque struct that represents the disk cache.
+ *
+ * `lws_diskcache_trim()` should be called at eg, 1s intervals to perform the
+ * cache dir monitoring and LRU autodelete in the background lazily. It can
+ * be done in its own thread or on a timer... it monitors the directories in a
+ * stateful way that stats one or more file in the cache per call, and keeps
+ * a list of the oldest files as it goes. When it completes a scan, if the
+ * aggregate size is over the limit, it will delete oldest files first to try
+ * to keep it under the limit.
+ *
+ * The cache size monitoring is extremely efficient in time and memory even when
+ * the cache directory becomes huge.
+ *
+ * `lws_diskcache_query()` is used to determine if the file already exists in
+ * the cache, or if it must be created. If it must be created, then the file
+ * is opened using a temp name that must be converted to a findable name with
+ * `lws_diskcache_finalize_name()` when the generation of the file contents are
+ * complete. Aborted cached files that did not complete generation will be
+ * flushed by the LRU eventually. If the file already exists, it is 'touched'
+ * to make it new again and the fd returned.

+ *
+ * ##HTTP header releated functions
+ *
+ * In lws the client http headers are temporarily stored in a pool, only for the
+ * duration of the http part of the handshake. It's because in most cases,
+ * the header content is ignored for the whole rest of the connection lifetime
+ * and would then just be taking up space needlessly.
+ *
+ * During LWS_CALLBACK_HTTP when the URI path is delivered is the last time
+ * the http headers are still allocated, you can use these apis then to
+ * look at and copy out interesting header content (cookies, etc)
+ *
+ * Notice that the header total length reported does not include a terminating
+ * '\0', however you must allocate for it when using the _copy apis. So the
+ * length reported for a header containing "123" is 3, but you must provide
+ * a buffer of length 4 so that "123\0" may be copied into it, or the copy
+ * will fail with a nonzero return code.
+ *
+ * In the special case of URL arguments, like ?x=1&y=2, the arguments are
+ * stored in a token named for the method, eg, WSI_TOKEN_GET_URI if it
+ * was a GET or WSI_TOKEN_POST_URI if POST. You can check the total
+ * length to confirm the method.
+ *
+ * For URL arguments, each argument is stored urldecoded in a "fragment", so
+ * you can use the fragment-aware api lws_hdr_copy_fragment() to access each
+ * argument in turn: the fragments contain urldecoded strings like x=1 or y=2.
+ *
+ * As a convenience, lws has an api that will find the fragment with a
+ * given name= part, lws_get_urlarg_by_name().

+ * ##Allocated Chunks
+ *
+ * If you know you will be allocating a large, unknown number of same or
+ * differently sized objects, it's certainly possible to do it with libc
+ * malloc. However the allocation cost in time and memory overhead can
+ * add up, and deallocation means walking the structure of every object and
+ * freeing them in turn.
+ *
+ * lwsac (LWS Allocated Chunks) allocates chunks intended to be larger
+ * than your objects (4000 bytes by default) which you linearly allocate from
+ * using lwsac_use().
+ *
+ * If your next request won't fit in the current chunk, a new chunk is added
+ * to the chain of chunks and the allocaton done from there. If the request
+ * is larger than the chunk size, an oversize chunk is created to satisfy it.
+ *
+ * When you are finished with the allocations, you call lwsac_free() and
+ * free all the *chunks*. So you may have thousands of objects in the chunks,
+ * but they are all destroyed with the chunks without having to deallocate them
+ * one by one pointlessly.

+ * ##lws_ring: generic ringbuffer struct
+ *
+ * Provides an abstract ringbuffer api supporting one head and one or an
+ * unlimited number of tails.
+ *
+ * All of the members are opaque and manipulated by lws_ring_...() apis.
+ *
+ * The lws_ring and its buffer is allocated at runtime on the heap, using
+ *
+ * - lws_ring_create()
+ * - lws_ring_destroy()
+ *
+ * It may contain any type, the size of the "element" stored in the ring
+ * buffer and the number of elements is given at creation time.
+ *
+ * When you create the ringbuffer, you can optionally provide an element
+ * destroy callback that frees any allocations inside the element. This is then
+ * automatically called for elements with no tail behind them, ie, elements
+ * which don't have any pending consumer are auto-freed.
+ *
+ * Whole elements may be inserted into the ringbuffer and removed from it, using
+ *
+ * - lws_ring_insert()
+ * - lws_ring_consume()
+ *
+ * You can find out how many whole elements are free or waiting using
+ *
+ * - lws_ring_get_count_free_elements()
+ * - lws_ring_get_count_waiting_elements()
+ *
+ * In addition there are special purpose optional byte-centric apis
+ *
+ * - lws_ring_next_linear_insert_range()
+ * - lws_ring_bump_head()
+ *
+ * which let you, eg, read() directly into the ringbuffer without needing
+ * an intermediate bounce buffer.
+ *
+ * The accessors understand that the ring wraps, and optimizes insertion and
+ * consumption into one or two memcpy()s depending on if the head or tail
+ * wraps.
+ *
+ * lws_ring only supports a single head, but optionally multiple tails with
+ * an API to inform it when the "oldest" tail has moved on. You can give
+ * NULL where-ever an api asks for a tail pointer, and it will use an internal
+ * single tail pointer for convenience.
+ *
+ * The "oldest tail", which is the only tail if you give it NULL instead of

+ * POSTed form arguments, both using simple urlencoded and multipart transfer
+ * encoding.
+ *
+ * It's capable of handling file uploads as well a named input parsing,
+ * and the apis are the same for both form upload styles.
+ *
+ * You feed it a list of parameter names and it creates pointers to the
+ * urldecoded arguments: file upload parameters pass the file data in chunks to
+ * a user-supplied callback as they come.
+ *
+ * Since it's stateful, it handles the incoming data needing more than one
+ * POST_BODY callback and has no limit on uploaded file size.

+ * (for lws use) [====== user buffer ======]
+ *
+ * This allows us to add protocol info before and after the data, and send as
+ * one packet on the network without payload copying, for maximum efficiency.
+ *
+ * So for example you need this kind of code to use lws_write with a
+ * 128-byte payload
+ *
+ * char buf[LWS_PRE + 128];
+ *
+ * // fill your part of the buffer... for example here it's all zeros

+ *
+ * LWS_PRE is at least the frame nonce + 2 header + 8 length
+ * LWS_SEND_BUFFER_POST_PADDING is deprecated, it's now 0 and can be left off.
+ * The example apps no longer use it.
+ *
+ * Pad LWS_PRE to the CPU word size, so that word references
+ * to the address immediately after the padding won't cause an unaligned access
+ * error. Sometimes for performance reasons the recommended padding is even
+ * larger than sizeof(void *).
+ *
+ * In the case of sending using websocket protocol, be sure to allocate
+ * valid storage before and after buf as explained above. This scheme
+ * allows maximum efficiency of sending data and protocol in a single
+ * packet while not burdening the user code with any protocol knowledge.
+ *
+ * Return may be -1 for a fatal error needing connection close, or the

+ *
+ * Truncated Writes
+ * ================
+ *
+ * The OS may not accept everything you asked to write on the connection.
+ *
+ * Posix defines POLLOUT indication from poll() to show that the connection
+ * will accept more write data, but it doesn't specifiy how much. It may just
+ * accept one byte of whatever you wanted to send.
+ *
+ * LWS will buffer the remainder automatically, and send it out autonomously.
+ *
+ * During that time, WRITABLE callbacks will be suppressed.
+ *
+ * This is to handle corner cases where unexpectedly the OS refuses what we
+ * usually expect it to accept. You should try to send in chunks that are
+ * almost always accepted in order to avoid the inefficiency of the buffering.

+# Abstract protocols and transports
+
+## Overview
+
+Until now protocol implementations in lws have been done directly
+to the network-related apis inside lws.
+
+In an effort to separate out completely network implementation
+details from protocol specification, lws now supports
+"abstract protocols" and "abstract transports".
+
+
+
+The concept is that the implementation is split into two separate
+chunks of code hidden behind "ops" structs... the "abstract protocol"
+implementation is responsible for the logical protocol operation
+and reads and writes only memory buffers.
+
+The "abstract transport" implementation is responsible for sending
+and receiving buffers on some kind of transport, and again is hidden
+behind a standardized ops struct.
+
+In the system, both the abstract protocols and transports are
+found by their name.
+
+An actual "connection" is created by calling a generic api
+`lws_abs_bind_and_create_instance()` to instantiate the
+combination of a protocol and a transport.
+
+This makes it possible to confidently offer the same protocol on
+completely different transports, eg, like serial, or to wire
+up the protocol implementation to a test jig sending canned
+test vectors and confirming the response at buffer level, without
+any network. The abstract protocol itself has no relationship
+to the transport at all and is completely unchanged by changes
+to the transport.
+
+In addition, generic tokens to control settings in both the
+protocol and the transport are passed in at instantiation-time,
+eg, controlling the IP address targeted by the transport.
+
+lws SMTP client support has been rewritten to use the new scheme,
+and lws provides a raw socket transport built-in.
+
+## Public API
+
+The public api for defining abstract protocols and transports is
+found at
+
+ - [abstract.h](https://libwebsockets.org/git/libwebsockets/tree/include/libwebsockets/abstract/abstract.h)
+ - [protocols.h](https://libwebsockets.org/git/libwebsockets/tree/include/libwebsockets/abstract/protocols.h)
+ - [transports.h](https://libwebsockets.org/git/libwebsockets/tree/include/libwebsockets/abstract/transports.h)
+
+### `lws_abs_t`
+
+The main structure that defines the abstraction is `lws_abs_t`,
+this is a name and then pointers to the protocol and transport,
+optional tokens to control both the protocol and transport,
+and pointers to private allocations for both the
+protocol and transport when instantiated.
+
+The transport is selected using
+
+```
+LWS_VISIBLE LWS_EXTERN const lws_abs_transport_t *
+lws_abs_transport_get_by_name(const char *name);
+```
+
+and similarly the protocol by
+
+```
+LWS_VISIBLE LWS_EXTERN const lws_abs_protocol_t *
+lws_abs_protocol_get_by_name(const char *name);
+```
+
+At the moment only "`raw-skt`" is defined as an lws built-in, athough
+you can also create your own mock transport the same way for creating
+test jigs.
+
+|transport op|meaning|
+|---|---|
+|`tx()`|transmit a buffer|
+|`client_conn()`|start a connection to a peer|
+|`close()`|request to close the connection to a peer|
+|`ask_for_writeable()`|request a `writeable()` callback when tx can be used|
+|`set_timeout()`|set a timeout that will close the connection if reached|
+|`state()`|check if the connection is established and can carry traffic|
+
+These are called by the protocol to get things done and make queries
+through the abstract transport.
+
+|protocol op|meaning|
+|---|---|
+|`accept()`|The peer has accepted the transport connection|
+|`rx()`|The peer has sent us some payload|
+|`writeable()`|The connection to the peer can take more tx|
+|`closed()`|The connection to the peer has closed|
+|`heartbeat()`|Called periodically even when no network events|
+
+These are called by the transport to inform the protocol of events
+and traffic.
+
+### Instantiation
+
+The user fills an lws_abs_t and passes a pointer to it to
+`lws_abs_bind_and_create_instance()` to create an instantiation
+of the protocol + transport.
+
+### `lws_token_map_t`
+
+The abstract protocol has no idea about a network or network addresses
+or ports or whatever... it may not even be hooked up to one.
+
+If the transport it is bound to wants things like that, they are passed
+in using an array of `lws_token_map_t` at instantiation time.
+
+For example this is passed to the raw socket protocol in the smtp client
+minimal example to control where it would connect to:
+
+```
+static const lws_token_map_t smtp_abs_tokens[] = {
+{
+ .u = { .value = "127.0.0.1" },
+ .name_index = LTMI_PEER_DNS_ADDRESS,
+}, {
+ .u = { .lvalue = 25l },
+ .name_index = LTMI_PEER_PORT,
+}};
+```
+
+## Steps for adding new abstract protocols
+
+ - add the public header in `./include/libwebsockets/abstract/protocols/`
+ - add a directory under `./lib/abstract/protocols/`
+ - add your protocol sources in the new directory
+ - in CMakeLists.txt:
+ - add an `LWS_WITH_xxx` for your protocol
+ - search for "using any abstract protocol" and add your `LWS_WITH_xxx` to
+ the if so it also sets `LWS_WITH_ABSTRACT` if any set
+ - add a clause to append your source to SOURCES if `LWS_WITH_xxx` enabled
+ - add your `lws_abs_protocol` to the list `available_abs_protocols` in
+ `./lib/abstract/abstract.c`
+
+## Steps for adding new abstract transports
+
+ - add the public header in `./include/libwebsockets/abstract/transports/`
+ - add your transport sources under `./lib/abstract/transports/`
+ - in CMakeLists.txt append your transport sources to SOURCES if `LWS_WITH_ABSTRACT`
+ and any other cmake conditionals
+ - add an extern for your transport `lws_protocols` in `./lib/core-net/private.h`
+ - add your transport `lws_protocols` to `available_abstract_protocols` in
+ `./lib/core-net/vhost.c`
+ - add your `lws_abs_transport` to the list `available_abs_transports` in
+ `./lib/abstract/abstract.c`
+
+# Protocol testing
+
+## unit tests
+
+lws features an abstract transport designed to facilitate unit testing. This
+contains an lws_sequencer that performs the steps of tests involving sending the
+protocol test vector buffers and confirming the response of the protocol matches
+the test vectors.
+
+## test-sequencer
+
+test-sequencer is a helper that sequences running an array of unit tests and
+collects the statistics and gives a PASS / FAIL result.
+
+See the SMTP client api test for an example of how to use.

+## Information for new event lib implementers
+
+### Introduction
+
+By default lws has built-in support for POSIX poll() as the event loop.
+
+However either to get access to epoll() or other platform specific better
+poll waits, or to integrate with existing applications already using a
+specific event loop, it can be desirable for lws to use another external
+event library, like libuv, libevent or libev.
+
+### Code placement
+
+The code specific to the event library should live in `./lib/event-libs/**lib name**`
+
+### Allowing control over enabling event libs
+
+All event libs should add a cmake define `LWS_WITH_**lib name**` and make its build
+dependent on it in CMakeLists.txt. Export the cmakedefine in `./cmake/lws_config.h.in`
+as well so user builds can understand if the event lib is available in the lws build it is
+trying to bind to.
+
+If the event lib is disabled in cmake, nothing in its directory is built or referenced.
+
+### Event loop ops struct
+
+The event lib support is defined by `struct lws_event_loop_ops` in `lib/event-libs/private.h`,
+each event lib support instantiates one of these and fills in the appropriate ops
+callbacks to perform its job. By convention that lives in
+`./lib/event-libs/**lib name**/**lib_name**.c`.
+
+### Private event lib declarations
+
+Truly private declarations for the event lib can go in the event-libs directory as you like.
+However when the declarations must be accessible to other things in lws build, eg,
+the event lib support adds members to `struct lws` when enabled, they should be in the
+event lib supporr directory in a file `private.h`.
+
+Search for "bring in event libs private declarations" in `./lib/core/private.h
+and add your private event lib support file there following the style used for the other
+event libs, eg,
+
+```
+#if defined(LWS_WITH_LIBUV)
+ #include "event-libs/libuv/private.h"
+#endif
+```
+
+If the event lib support is disabled at cmake, nothing from its private.h should be used anywhere.
+
+### Integrating event lib assets to lws
+
+If your event lib needs special storage in lws objects, that's no problem. But to keep
+things sane, there are some rules.
+
+ - declare a "container struct" in your private.h for everything, eg, the libuv event
+ lib support need to add its own assets in the perthread struct, it declares in its private.h
+
+```
+struct lws_pt_eventlibs_libuv {
+ uv_loop_t *io_loop;
+ uv_signal_t signals[8];
+ uv_timer_t timeout_watcher;
+ uv_timer_t hrtimer;
+ uv_idle_t idle;
+};
+```
+
+ - add your event lib content in one place in the related lws struct, protected by `#if defined(LWS_WITH_**lib name**)`,
+ eg, again for LWS_WITH_LIBUV
+
+```
+struct lws_context_per_thread {
+
+...
+
+#if defined(LWS_WITH_LIBUV)
+ struct lws_pt_eventlibs_libuv uv;
+#endif
+
+...
+```
+
+### Adding to lws available event libs list
+
+Edit the NULL-terminated array `available_event_libs` at the top of `./lib/context.c` to include
+a pointer to your new event lib support's ops struct, following the style already there.
+
+```
+const struct lws_event_loop_ops *available_event_libs[] = {
+#if defined(LWS_WITH_POLL)
+ &event_loop_ops_poll,
+#endif
+#if defined(LWS_WITH_LIBUV)
+ &event_loop_ops_uv,
+#endif
+...
+```
+
+This is used to provide a list of avilable configured backends.
+
+### Enabling event lib adoption
+
+You need to add a `LWS_SERVER_OPTION...` flag as necessary in `./lib/libwebsockets.h`
+`enum lws_context_options`, and follow the existing code in `lws_create_context()`
+to convert the flag into binding your ops struct to the context.
+
+### Implementation of the event lib bindings
+
+Study eg libuv implementation, using the available ops in the struct lws_event_loop_ops
+as a guide.
+
+### Destruction
+
+Ending the event loop is generally a bit tricky, because if the event loop is internal
+to the lws context, you cannot destroy it while the event loop is running.
+
+Don't add special exports... we tried that, it's a huge mess. The same user code should be able
+work with any of the event loops including poll.
+
+The solution we found was hide the different processing necessary for the different cases in
+lws_destroy_context(). To help with that there are ops available at two different places in
+the context destroy processing.

+# JOSE support
+
+JOSE is a set of web standards aimed at encapsulating crypto
+operations flexibly inside JSON objects.
+
+Lws provides lightweight apis to performs operations on JWK, JWS and JWE
+independent of the tls backend in use. The JSON parsing is handled by the lws
+lejp stream parser.
+
+|Part|RFC|Function|
+|---|---|---|
+|JWS|[RFC7515](https://tools.ietf.org/html/rfc7515)|JSON Web Signatures|
+|JWE|[RFC7516](https://tools.ietf.org/html/rfc7516)|JSON Web Encryption|
+|JWK|[RFC7517](https://tools.ietf.org/html/rfc7517)|JSON Web Keys|
+|JWA|[RFC7518](https://tools.ietf.org/html/rfc7518)|JSON Web Algorithms|
+
+JWA is a set of recommendations for which combinations of algorithms
+are deemed desirable and secure, which implies what must be done for
+useful implementations of JWS, JWE and JWK.
+
+## Supported algorithms
+
+### Supported keys
+
+ - All RFC7517 / JWK forms: octet, RSA and EC
+
+ - singleton and keys[] arrays of keys supported
+
+### Symmetric ciphers
+
+ - All common AES varaiants: CBC, CFB128, CFB8, CTR, EVB, OFB, KW and XTS
+
+### Asymmetric ciphers
+
+ - RSA
+
+ - EC (P-256, P-384 and P-521 JWA curves)
+
+### Payload auth and crypt
+
+ - AES_128_CBC_HMAC_SHA_256
+ - AES_192_CBC_HMAC_SHA_384
+ - AES_256_CBC_HMAC_SHA_512
+ - AES_128_GCM
+
+For the required and recommended asymmetric algorithms, support currently
+looks like this
+
+|JWK kty|JWA|lws|
+|---|---|---|
+|EC|Recommended+|yes|
+|RSA|Required|yes|
+|oct|Required|yes|
+
+|JWE alg|JWA|lws|
+|---|---|---|
+|RSA1_5|Recommended-|yes|
+|RSA-OAEP|Recommended+|no|
+|ECDH-ES|Recommended+|no|
+
+|JWS alg|JWA|lws|
+|---|---|---|
+|HS256|Required|yes|
+|RS256|Recommended+|yes|
+|ES256|Recommended|yes|
+
+## Minimal Example tools
+
+[JWK](https://libwebsockets.org/git/libwebsockets/tree/minimal-examples/crypto/minimal-crypto-jwk)
+

+## API tests
+
+See `./minimal-examples/api-tests/api-test-jose/` for example test code.
+The tests are built and confirmed during CI.

+ * From RFC7518 JWA
+ *
+ * 4.6. Key Agreement with Elliptic Curve Diffie-Hellman Ephemeral Static
+ * (ECDH-ES)
+ *
+ * This section defines the specifics of key agreement with Elliptic
+ * Curve Diffie-Hellman Ephemeral Static [RFC6090], in combination with
+ * the Concat KDF, as defined in Section 5.8.1 of [NIST.800-56A]. The
+ * key agreement result can be used in one of two ways:
+ *
+ * 1. directly as the Content Encryption Key (CEK) for the "enc"
+ * algorithm, in the Direct Key Agreement mode, or
+ *
+ * 2. as a symmetric key used to wrap the CEK with the "A128KW",
+ * "A192KW", or "A256KW" algorithms, in the Key Agreement with Key
+ * Wrapping mode.
+ *
+ * A new ephemeral public key value MUST be generated for each key
+ * agreement operation.
+ *
+ * In Direct Key Agreement mode, the output of the Concat KDF MUST be a
+ * key of the same length as that used by the "enc" algorithm. In this
+ * case, the empty octet sequence is used as the JWE Encrypted Key
+ * value. The "alg" (algorithm) Header Parameter value "ECDH-ES" is
+ * used in the Direct Key Agreement mode.
+ *
+ * In Key Agreement with Key Wrapping mode, the output of the Concat KDF
+ * MUST be a key of the length needed for the specified key wrapping
+ * algorithm. In this case, the JWE Encrypted Key is the CEK wrapped
+ * with the agreed-upon key.
+ *
+ * The following "alg" (algorithm) Header Parameter values are used to
+ * indicate that the JWE Encrypted Key is the result of encrypting the
+ * CEK using the result of the key agreement algorithm as the key
+ * encryption key for the corresponding key wrapping algorithm:
+ *
+ * +-----------------+-------------------------------------------------+
+ * | "alg" Param | Key Management Algorithm |
+ * | Value | |
+ * +-----------------+-------------------------------------------------+
+ * | ECDH-ES+A128KW | ECDH-ES using Concat KDF and CEK wrapped with |
+ * | | "A128KW" |
+ * | ECDH-ES+A192KW | ECDH-ES using Concat KDF and CEK wrapped with |
+ * | | "A192KW" |
+ * | ECDH-ES+A256KW | ECDH-ES using Concat KDF and CEK wrapped with |
+ * | | "A256KW" |
+ * +-----------------+-------------------------------------------------+
+ *
+ * 4.6.1. Header Parameters Used for ECDH Key Agreement
+ *
+ * The following Header Parameter names are used for key agreement as
+ * defined below.
+ *
+ * 4.6.1.1. "epk" (Ephemeral Public Key) Header Parameter
+ *
+ * The "epk" (ephemeral public key) value created by the originator for
+ * the use in key agreement algorithms. This key is represented as a
+ * JSON Web Key [JWK] public key value. It MUST contain only public key
+ * parameters and SHOULD contain only the minimum JWK parameters
+ * necessary to represent the key; other JWK parameters included can be
+ * checked for consistency and honored, or they can be ignored. This
+ * Header Parameter MUST be present and MUST be understood and processed
+ * by implementations when these algorithms are used.
+ *
+ * 4.6.1.2. "apu" (Agreement PartyUInfo) Header Parameter
+ *
+ * The "apu" (agreement PartyUInfo) value for key agreement algorithms
+ * using it (such as "ECDH-ES"), represented as a base64url-encoded
+ * string. When used, the PartyUInfo value contains information about
+ * the producer. Use of this Header Parameter is OPTIONAL. This Header
+ * Parameter MUST be understood and processed by implementations when
+ * these algorithms are used.
+ *
+ * 4.6.1.3. "apv" (Agreement PartyVInfo) Header Parameter
+ *
+ * The "apv" (agreement PartyVInfo) value for key agreement algorithms
+ * using it (such as "ECDH-ES"), represented as a base64url encoded
+ * string. When used, the PartyVInfo value contains information about
+ * the recipient. Use of this Header Parameter is OPTIONAL. This
+ * Header Parameter MUST be understood and processed by implementations
+ * when these algorithms are used.
+ *
+ * 4.6.2. Key Derivation for ECDH Key Agreement
+ *
+ * The key derivation process derives the agreed-upon key from the
+ * shared secret Z established through the ECDH algorithm, per
+ * Section 6.2.2.2 of [NIST.800-56A].
+ *
+ * Key derivation is performed using the Concat KDF, as defined in
+ * Section 5.8.1 of [NIST.800-56A], where the Digest Method is SHA-256.
+ * The Concat KDF parameters are set as follows:
+ *
+ * Z
+ * This is set to the representation of the shared secret Z as an
+ * octet sequence.
+ *
+ * keydatalen
+ * This is set to the number of bits in the desired output key. For
+ * "ECDH-ES", this is length of the key used by the "enc" algorithm.
+ * For "ECDH-ES+A128KW", "ECDH-ES+A192KW", and "ECDH-ES+A256KW", this
+ * is 128, 192, and 256, respectively.
+ *
+ * AlgorithmID
+ * The AlgorithmID value is of the form Datalen || Data, where Data
+ * is a variable-length string of zero or more octets, and Datalen is
+ * a fixed-length, big-endian 32-bit counter that indicates the
+ * length (in octets) of Data. In the Direct Key Agreement case,
+ * Data is set to the octets of the ASCII representation of the "enc"
+ * Header Parameter value. In the Key Agreement with Key Wrapping
+ * case, Data is set to the octets of the ASCII representation of the
+ * "alg" (algorithm) Header Parameter value.
+ *
+ * PartyUInfo
+ * The PartyUInfo value is of the form Datalen || Data, where Data is
+ * a variable-length string of zero or more octets, and Datalen is a
+ * fixed-length, big-endian 32-bit counter that indicates the length
+ * (in octets) of Data. If an "apu" (agreement PartyUInfo) Header
+ * Parameter is present, Data is set to the result of base64url
+ * decoding the "apu" value and Datalen is set to the number of
+ * octets in Data. Otherwise, Datalen is set to 0 and Data is set to
+ * the empty octet sequence.
+ *
+ * PartyVInfo
+ * The PartyVInfo value is of the form Datalen || Data, where Data is
+ * a variable-length string of zero or more octets, and Datalen is a
+ * fixed-length, big-endian 32-bit counter that indicates the length
+ * (in octets) of Data. If an "apv" (agreement PartyVInfo) Header
+ * Parameter is present, Data is set to the result of base64url
+ * decoding the "apv" value and Datalen is set to the number of
+ * octets in Data. Otherwise, Datalen is set to 0 and Data is set to
+ * the empty octet sequence.
+ *
+ * SuppPubInfo
+ * This is set to the keydatalen represented as a 32-bit big-endian
+ * integer.
+ *
+ * SuppPrivInfo
+ * This is set to the empty octet sequence.
+ *
+ * Applications need to specify how the "apu" and "apv" Header
+ * Parameters are used for that application. The "apu" and "apv" values
+ * MUST be distinct, when used. Applications wishing to conform to
+ * [NIST.800-56A] need to provide values that meet the requirements of
+ * that document, e.g., by using values that identify the producer and
+ * consumer. Alternatively, applications MAY conduct key derivation in
+ * a manner similar to "Diffie-Hellman Key Agreement Method" [RFC2631]:
+ * in that case, the "apu" parameter MAY either be omitted or represent
+ * a random 512-bit value (analogous to PartyAInfo in Ephemeral-Static
+ * mode in RFC 2631) and the "apv" parameter SHOULD NOT be present.
+ *
+ */
+
+
+/*
+ * - ECDH-ES[-variant] comes in the jose "alg" and just covers key agreement.
+ * The "enc" action is completely separate and handled elsewhere. However
+ * the key size throughout is determined by the needs of the "enc" action.

- * \param in: Pointer used for some callback reasons

- *
- * Each extension that is active on a particular connection receives
- * callbacks during the connection lifetime to allow the extension to
- * operate on websocket data and manage itself.
- *
- * Libwebsockets takes care of allocating and freeing "user" memory for
- * each active extension on each connection. That is what is pointed to
- * by the user parameter.
- *
- * LWS_EXT_CB_CONSTRUCT: called when the server has decided to
- * select this extension from the list provided by the client,
- * just before the server will send back the handshake accepting
- * the connection with this extension active. This gives the
- * extension a chance to initialize its connection context found
- * in user.
- *
- * LWS_EXT_CB_CLIENT_CONSTRUCT: same as LWS_EXT_CB_CONSTRUCT
- * but called when client is instantiating this extension. Some
- * extensions will work the same on client and server side and then
- * you can just merge handlers for both CONSTRUCTS.
- *
- * LWS_EXT_CB_DESTROY: called when the connection the extension was
- * being used on is about to be closed and deallocated. It's the
- * last chance for the extension to deallocate anything it has
- * allocated in the user data (pointed to by user) before the
- * user data is deleted. This same callback is used whether you
- * are in client or server instantiation context.
- *
- * LWS_EXT_CB_PACKET_RX_PREPARSE: when this extension was active on
- * a connection, and a packet of data arrived at the connection,
- * it is passed to this callback to give the extension a chance to
- * change the data, eg, decompress it. user is pointing to the
- * extension's private connection context data, in is pointing
- * to an lws_tokens struct, it consists of a char * pointer called
- * token, and an int called token_len. At entry, these are
- * set to point to the received buffer and set to the content
- * length. If the extension will grow the content, it should use
- * a new buffer allocated in its private user context data and
- * set the pointed-to lws_tokens members to point to its buffer.
- *
- * LWS_EXT_CB_PACKET_TX_PRESEND: this works the same way as
- * LWS_EXT_CB_PACKET_RX_PREPARSE above, except it gives the
- * extension a chance to change websocket data just before it will
- * be sent out. Using the same lws_token pointer scheme in in,
- * the extension can change the buffer and the length to be
- * transmitted how it likes. Again if it wants to grow the
- * buffer safely, it should copy the data into its own buffer and
- * set the lws_tokens token pointer to it.

- * In lws the client http headers are temporarily stored in a pool, only for the

- * the header content is ignored for the whole rest of the connection lifetime
- * and would then just be taking up space needlessly.
- *

- *
- * Notice that the header total length reported does not include a terminating
- * '\0', however you must allocate for it when using the _copy apis. So the
- * length reported for a header containing "123" is 3, but you must provide
- * a buffer of length 4 so that "123\0" may be copied into it, or the copy
- * will fail with a nonzero return code.
- *
- * In the special case of URL arguments, like ?x=1&y=2, the arguments are
- * stored in a token named for the method, eg, WSI_TOKEN_GET_URI if it
- * was a GET or WSI_TOKEN_POST_URI if POST. You can check the total
- * length to confirm the method.
- *
- * For URL arguments, each argument is stored urldecoded in a "fragment", so
- * you can use the fragment-aware api lws_hdr_copy_fragment() to access each
- * argument in turn: the fragments contain urldecoded strings like x=1 or y=2.

- * the send buffer has to have LWS_PRE bytes valid BEFORE
- * the buffer pointer you pass to lws_write().
- *
- * This allows us to add protocol info before and after the data, and send as
- * one packet on the network without payload copying, for maximum efficiency.
- *
- * So for example you need this kind of code to use lws_write with a
- * 128-byte payload
- *
- * char buf[LWS_PRE + 128];
- *
- * // fill your part of the buffer... for example here it's all zeros
- * memset(&buf[LWS_PRE], 0, 128);
- *
- * lws_write(wsi, &buf[LWS_PRE], 128, LWS_WRITE_TEXT);
- *
- * When sending HTTP, with
- *
- * LWS_WRITE_HTTP,
- * LWS_WRITE_HTTP_HEADERS
- * LWS_WRITE_HTTP_FINAL
- *
- * there is no protocol data prepended, and don't need to take care about the
- * LWS_PRE bytes valid before the buffer pointer.
- *
- * LWS_PRE is at least the frame nonce + 2 header + 8 length
- * LWS_SEND_BUFFER_POST_PADDING is deprecated, it's now 0 and can be left off.
- * The example apps no longer use it.
- *
- * Pad LWS_PRE to the CPU word size, so that word references
- * to the address immediately after the padding won't cause an unaligned access
- * error. Sometimes for performance reasons the recommended padding is even
- * larger than sizeof(void *).
- *
- * In the case of sending using websocket protocol, be sure to allocate
- * valid storage before and after buf as explained above. This scheme
- * allows maximum efficiency of sending data and protocol in a single
- * packet while not burdening the user code with any protocol knowledge.
- *
- * Return may be -1 for a fatal error needing connection close, or the
- * number of bytes sent.
- *
- * Truncated Writes
- * ================
- *
- * The OS may not accept everything you asked to write on the connection.
- *
- * Posix defines POLLOUT indication from poll() to show that the connection
- * will accept more write data, but it doesn't specifiy how much. It may just
- * accept one byte of whatever you wanted to send.
- *
- * LWS will buffer the remainder automatically, and send it out autonomously.
- *
- * During that time, WRITABLE callbacks will be suppressed.
- *
- * This is to handle corner cases where unexpectedly the OS refuses what we
- * usually expect it to accept. You should try to send in chunks that are
- * almost always accepted in order to avoid the inefficiency of the buffering.

- * These apis let you communicate with a local SMTP server to send email from

- * Your system should have postfix, sendmail or another MTA listening on port
- * 25 and able to send email using the "mail" commandline app. Usually distro
- * MTAs are configured for this by default.
- *
- * It runs via its own libuv events if initialized (which requires giving it
- * a libuv loop to attach to).
- *
- * It operates using three callbacks, on_next() queries if there is a new email
- * to send, on_get_body() asks for the body of the email, and on_sent() is
- * called after the email is successfully sent.
- *
- * To use it
- *
- * - create an lws_email struct
- *
- * - initialize data, loop, the email_* strings, max_content_size and
- * the callbacks
- *
- * - call lws_email_init()
- *
- * When you have at least one email to send, call lws_email_check() to

+# LWS Full Text Search
+
+## Introduction
+
+
+
+The general approach is to scan one or more UTF-8 input text "files" (they may
+only exist in memory) and create an in-memory optimized trie for every token in
+the file.
+
+This can then be serialized out to disk in the form of a single index file (no
+matter how many input files were involved or how large they were).
+
+The implementation is designed to be modest on memory and cpu for both index
+creation and querying, and suitable for weak machines with some kind of random
+access storage. For searching only memory to hold results is required, the
+actual searches and autocomplete suggestions are done very rapidly by seeking
+around structures in the on-disk index file.

+Live Demo|[https://libwebsockets.org/ftsdemo/](https://libwebsockets.org/ftsdemo/)
+
+## Query API overview
+
+Searching returns a potentially very large lwsac allocated object, with contents
+and max size controlled by the members of a struct lws_fts_search_params passed
+to the search function. Three kinds of result are possible:
+
+### Autocomplete suggestions
+
+These are useful to provide lists of extant results in
+realtime as the user types characters that constrain the search. So if the
+user has typed 'len', any hits for 'len' itself are reported along with
+'length', and whatever else is in the index beginning 'len'.. The results are
+selected using and are accompanied by an aggregated count of results down that
+path, and the results so the "most likely" results already measured by potential
+hits appear first.
+
+These results are in a linked-list headed by `result.autocomplete_head` and
+each is in a `struct lws_fts_result_autocomplete`.
+
+They're enabled in the search results by giving the flag
+ `LWSFTS_F_QUERY_AUTOCOMPLETE` in the search parameter flags.
+
+### Filepath results
+
+Simply a list of input files containing the search term with some statistics,
+one file is mentioned in a `struct lws_fts_result_filepath` result struct.
+
+This would be useful for creating a selection UI to "drill down" to individual
+files when there are many with matches.
+
+This is enabled by the `LWSFTS_F_QUERY_FILES` search flag.
+
+### Filepath and line results
+
+Same as the file path list, but for each filepath, information on the line
+numbers and input file offset where the line starts are provided.
+
+This is enabled by `LWSFTS_F_QUERY_FILE_LINES`... if you additionally give
+`LWSFTS_F_QUERY_QUOTE_LINE` flag then the contents of each hit line from the
+input file are also provided.
+
+## Result format inside the lwsac
+
+A `struct lws_fts_result` at the start of the lwsac contains heads for linked-
+lists of autocomplete and filepath results inside the lwsac.
+
+For autocomplete suggestions, the string itself is immediately after the
+`struct lws_fts_result_autocomplete` in memory. For filepath results, after
+each `struct lws_fts_result_filepath` is
+
+ - match information depending on the flags given to the search
+ - the filepath string
+
+You can always skip the line number table to get the filepath string by adding
+.matches_length to the address of the byte after the struct.
+
+The matches information is either
+
+ - 0 bytes per match
+
+ - 2x int32_t per match (8 bytes) if `LWSFTS_F_QUERY_FILE_LINES` given... the
+ first is the native-endian line number of the match, the second is the
+ byte offset in the original file where that line starts
+
+ - 2 x int32_t as above plus a const char * if `LWSFTS_F_QUERY_QUOTE_LINE` is
+ also given... this points to a NUL terminated string also stored in the
+ results lwsac that contains up to 255 chars of the line from the original
+ file. In some cases, the original file was either virtual (you are indexing
+ a git revision) or is not stored with the index, in that case you can't
+ usefully use `LWSFTS_F_QUERY_QUOTE_LINE`.
+
+To facilitate interpreting what is stored per match, the original search flags
+that created the result are stored in the `struct lws_fts_result`.
+
+## Indexing In-memory and serialized to file
+
+When creating the trie, in-memory structs are used with various optimization
+schemes trading off memory usage for speed. While in-memory, it's possible to
+add more indexed filepaths to the single index. Once the trie is complete in
+terms of having indexed everything, it is serialized to disk.
+
+These contain many additional housekeeping pointers and trie entries which can
+be optimized out. Most in-memory values must be held literally in large types,
+whereas most of the values in the serialized file use smaller VLI which use
+more or less bytes according to the value. So the peak memory requirements for
+large tries are much bigger than the size of the serialized trie file that is
+output.
+
+For the linux kernel at 4.14 and default indexing whitelist on a 2.8GHz AMD
+threadripper (using one thread), the stats are:
+
+Name|Value
+---|---
+Files indexed|52932
+Input corpus size|694MiB
+Indexing cpu time|50.1s (>1000 files / sec; 13.8MBytes/sec)
+Peak alloc|78MiB
+Serialization time|202ms
+Trie File size|347MiB
+
+To index libwebsockets master under the same conditions:
+
+Name|Value
+---|---
+Files indexed|489
+Input corpus size|3MiB
+Indexing time|123ms
+Peak alloc|3MiB
+Serialization time|1ms
+Trie File size|1.4MiB
+
+
+Once it's generated, querying the trie file is very inexpensive, even when there
+are lots of results.
+
+ - trie entry child lists are kept sorted by the character they map to. This
+ allows discovering there is no match as soon as a character later in the
+ order than the one being matched is seen
+
+ - for the root trie, in addition to the linked-list child + sibling entries,
+ a 256-entry pointer table is associated with the root trie, allowing one-
+ step lookup. But as the table is 2KiB, it's too expensive to use on all
+ trie entries
+
+## Structure on disk
+
+All explicit multibyte numbers are stored in Network (MSB-first) byte order.
+
+ - file header
+ - filepath line number tables
+ - filepath information
+ - filepath map table
+ - tries, trie instances (hits), trie child tables
+
+### VLI coding
+
+VLI (Variable Length Integer) coding works like this
+
+[b7 EON] [b6 .. b0 DATA]
+
+If EON = 0, then DATA represents the Least-significant 7 bits of the number.
+if EON = 1, DATA represents More-significant 7-bits that should be shifted
+left until the byte with EON = 0 is found to terminate the number.
+
+The VLI used is predicated around 32-bit unsigned integers
+
+Examples:
+
+ - 0x30 = 48
+ - 0x81 30 = 176
+ - 0x81 0x80 0x00 = 16384
+
+Bytes | Range
+---|---
+1|<= 127
+2|<= 16K - 1
+3|<= 2M -1
+4|<= 256M - 1
+5|<= 4G - 1
+
+The coding is very efficient if there's a high probabilty the number being
+stored is not large. So it's great for line numbers for example, where most
+files have less that 16K lines and the VLI for the line number fits in 2 bytes,
+but if you meet a huge file, the VLI coding can also handle it.
+
+All numbers except a few in the headers that are actually written after the
+following data are stored using VLI for space- efficiency without limiting
+capability. The numbers that are fixed up after the fact have to have a fixed
+size and can't use VLI.
+
+### File header
+
+The first byte of the file header where the magic is, is "fileoffset" 0. All
+the stored "fileoffset"s are relative to that.
+
+The header has a fixed size of 16 bytes.
+
+size|function
+---|---
+32-bits|Magic 0xCA7A5F75
+32-bits|Fileoffset to root trie entry
+32-bits|Size of the trie file when it was created (to detect truncation)
+32-bits|Fileoffset to the filepath map
+32-bits|Number of filepaths
+
+### Filepath line tables
+
+Immediately after the file header are the line length tables.
+
+As the input files are parsed, line length tables are written for each file...
+at that time the rest of the parser data is held in memory so nothing else is
+in the file yet. These allow you to map logical line numbers in the file to
+file offsets space- and time- efficiently without having to walk through the
+file contents.
+
+The line information is cut into blocks, allowing quick skipping over the VLI
+data that doesn't contain the line you want just by following the 8-byte header
+part.
+
+Once you find the block with your line, you have to iteratively add the VLIs
+until you hit the one you want.
+
+For normal text files with average line length below 128, the VLIs will
+typically be a single byte. So a block of 200 line lengths is typically
+208 bytes long.
+
+There is a final linetable chunk consisting of all zeros to indicate the end
+of the filepath line chunk series for a filepath.
+
+size|function
+---|---
+16-bit|length of this chunk itself in bytes
+16-bit|count of lines covered in this chunk
+32-bit|count of bytes in the input file this chunk covers
+VLI...|for each line in the chunk, the number of bytes in the line
+
+
+### Filepaths
+
+The single trie in the file may contain information from multiple files, for
+example one trie may cover all files in a directory. The "Filepaths" are
+listed after the line tables, and referred to by index thereafter.
+
+For each filepath, one after the other:
+
+size|function
+---|---
+VLI|fileoffset of the start of this filepath's line table
+VLI|count of lines in the file
+VLI|length of filepath in bytes
+...|the filepath (with no NUL)
+
+### Filepath map
+
+To facilitate rapid filepath lookup, there's a filepath map table with a 32-bit
+fileoffset per filepath. This is the way to convert filepath indexes to
+information on the filepath like its name, etc
+
+size|function
+---|---
+32-bit...|fileoffset to filepath table for each filepath
+
+### Trie entries
+
+Immediately after that, the trie entries are dumped, for each one a header:
+
+#### Trie entry header
+
+size|function
+---|---
+VLI|Fileoffset of first file table in this trie entry instance list
+VLI|number of child trie entries this trie entry has
+VLI|number of instances this trie entry has
+
+The child list follows immediately after this header
+
+#### Trie entry instance file
+
+For each file that has instances of this symbol:
+
+size|function
+---|---
+VLI|Fileoffset of next file table in this trie entry instance list
+VLI|filepath index
+VLI|count of line number instances following
+
+#### Trie entry file line number table
+
+Then for the file mentioned above, a list of all line numbers in the file with
+the symbol in them, in ascending order. As a VLI, the median size per entry
+will typically be ~15.9 bits due to the probability of line numbers below 16K.
+
+size|function
+---|---
+VLI|line number
+...
+
+#### Trie entry child table
+
+For each child node
+
+size|function
+---|---
+VLI|file offset of child
+VLI|instance count belonging directly to this child
+VLI|aggregated number of instances down all descendent paths of child
+VLI|aggregated number of children down all descendent paths of child
+VLI|match string length
+...|the match string

+## LWS Allocated Chunks
+
+
+
+These apis provide a way to manage a linked-list of allocated chunks...
+
+[ HEAD alloc ] -> [ next alloc ] -> [ next alloc ] -> [ curr alloc ]
+
+... and sub-allocate trivially inside the chunks. These sub-allocations are
+not tracked by lwsac at all, there is a "used" high-water mark for each chunk
+that's simply advanced by the amount sub-allocated. If the allocation size
+matches the platform pointer alignment, there is zero overhead to sub-allocate
+(otherwise the allocation is padded to the next platform pointer alignment
+automatically).
+
+If you have an unknown amount of relatively little things to allocate, including
+strings or other unstructured data, lwsac is significantly more efficient than
+individual allocations using malloc or so.
+
+[lwsac full public api](https://libwebsockets.org/git/libwebsockets/tree/include/libwebsockets/lws-lwsac.h)
+
+## lwsac_use() api
+
+```
+/**
+ * lwsac_use - allocate / use some memory from a lwsac
+ *
+ * \param head: pointer to the lwsac list object
+ * \param ensure: the number of bytes we want to use
+ * \param chunk_size: 0, or the size of the chunk to (over)allocate if
+ * what we want won't fit in the current tail chunk. If
+ * 0, the default value of 4000 is used. If ensure is
+ * larger, it is used instead.
+ *
+ * This also serves to init the lwsac if *head is NULL. Basically it does
+ * whatever is necessary to return you a pointer to ensure bytes of memory
+ * reserved for the caller.
+ *
+ * Returns NULL if OOM.
+ */
+LWS_VISIBLE LWS_EXTERN void *
+lwsac_use(struct lwsac **head, size_t ensure, size_t chunk_size);
+```
+
+When you make an sub-allocation using `lwsac_use()`, you can either
+set the `chunk_size` arg to zero, defaulting to 4000, or a specific chunk size.
+In the event the requested sub-allocation exceeds the chunk size, the chunk
+size is increated to match it automatically for this allocation only.
+
+Subsequent `lwsac_use()` calls will advance internal pointers to use up the
+remaining space inside the current chunk if possible; if not enough remaining
+space it is skipped, a new allocation is chained on and the request pointed to
+there.
+
+Lwsac does not store information about sub-allocations. There is really zero
+overhead for individual sub-allocations (unless their size is not
+pointer-aligned, in which case the actual amount sub-allocated is rounded up to
+the next pointer alignment automatically). For structs, which are pointer-
+aligned naturally, and a chunk size relatively large for the sub-allocation
+size, lwsac is extremely efficient even for huge numbers of small allocations.
+
+This makes lwsac very effective when the total amount of allocation needed is
+not known at the start and may be large... it will simply add on chunks to cope
+with whatever happens.
+
+## lwsac_free() api
+
+```
+/**
+ * lwsac_free - deallocate all chunks in the lwsac and set head NULL
+ *
+ * \param head: pointer to the lwsac list object
+ *
+ * This deallocates all chunks in the lwsac, then sets *head to NULL. All
+ * lwsac_use() pointers are invalidated in one hit without individual frees.
+ */
+LWS_VISIBLE LWS_EXTERN void
+lwsac_free(struct lwsac **head);
+```
+
+When you are finished with the lwsac, you simply free the chain of allocated
+chunks using lwsac_free() on the lwsac head. There's no tracking or individual
+destruction of suballocations - the whole chain of chunks the suballocations
+live in are freed and invalidated all together.
+
+If the structs stored in the lwsac allocated things **outside** the lwsac, then the
+user must unwind through them and perform the frees. But the idea of lwsac is
+things stored in the lwsac also suballocate into the lwsac, and point into the
+lwsac if they need to, avoiding any need to visit them during destroy. It's
+like clearing up after a kids' party by gathering up a disposable tablecloth:
+no matter what was left on the table, it's all gone in one step.
+
+## lws_list_ptr helpers
+
+```
+/* sort may be NULL if you don't care about order */
+LWS_VISIBLE LWS_EXTERN void
+lws_list_ptr_insert(lws_list_ptr *phead, lws_list_ptr *add,
+ lws_list_ptr_sort_func_t sort);
+```
+
+A common pattern needed with sub-allocated structs is they are on one or more
+linked-list. To make that simple to do cleanly, lws_list... apis are provided
+along with a generic insertion function that can take a sort callback. These
+allow a struct to participate on multiple linked-lists simultaneously.

+## Threadpool
+
+### Overview
+
+
+
+An api that lets you create a pool of worker threads, and a queue of tasks that
+are bound to a wsi. Tasks in their own thread synchronize communication to the
+lws service thread of the wsi via `LWS_CALLBACK_SERVER_WRITEABLE` and friends.
+
+Tasks can produce some output, then return that they want to "sync" with the
+service thread. That causes a `LWS_CALLBACK_SERVER_WRITEABLE` in the service
+thread context, where the output can be consumed, and the task told to continue,
+or completed tasks be reaped.
+
+ALL of the details related to thread synchronization and an associated wsi in
+the lws service thread context are handled by the threadpool api, without needing
+any pthreads in user code.
+
+### Example
+
+https://libwebsockets.org/git/libwebsockets/tree/minimal-examples/ws-server/minimal-ws-server-threadpool
+
+### Lifecycle considerations
+
+#### Tasks vs wsi
+
+Although all tasks start out as being associated to a wsi, in fact the lifetime
+of a task and that of the wsi are not necessarily linked.
+
+You may start a long task, eg, that runs atomically in its thread for 30s, and
+at any time the client may close the connection, eg, close a browser window.
+
+There are arrangements that a task can "check in" periodically with lws to see
+if it has been asked to stop, allowing the task lifetime to be related to the
+wsi lifetime somewhat, but some tasks are going to be atomic and longlived.
+
+For that reason, at wsi close an ongoing task can detach from the wsi and
+continue until it ends or understands it has been asked to stop. To make
+that work, the task is created with a `cleanup` callback that performs any
+freeing independent of still having a wsi around to do it... the task takes over
+responsibility to free the user pointer on destruction when the task is created.
+
+
+
+#### Reaping completed tasks
+
+Once created, although tasks may run asynchronously, the task itself does not
+get destroyed on completion but added to a "done queue". Only when the lws
+service thread context queries the task state with `lws_threadpool_task_status()`
+may the task be reaped and memory freed.
+
+This is analogous to unix processes and `wait()`.
+
+If a task became detached from its wsi, then joining the done queue is enough
+to get the task reaped, since there's nobody left any more to synchronize the
+reaping with.
+
+### User interface
+
+The api is declared at https://libwebsockets.org/git/libwebsockets/tree/include/libwebsockets/lws-threadpool.h
+
+#### Threadpool creation / destruction
+
+The threadpool should be created at program or vhost init using
+`lws_threadpool_create()` and destroyed on exit or vhost destruction using
+first `lws_threadpool_finish()` and then `lws_threadpool_destroy()`.
+
+Threadpools should be named, varargs are provided on the create function
+to facilite eg, naming the threadpool by the vhost it's associated with.
+
+Threadpool creation takes an args struct with the following members:
+
+Member|function
+---|---
+threads|The maxiumum number of independent threads in the pool
+max_queue_depth|The maximum number of tasks allowed to wait for a place in the pool
+
+#### Task creation / destruction
+
+Tasks are created and queued using `lws_threadpool_enqueue()`, this takes an
+args struct with the following members
+
+Member|function
+---|---
+wsi|The wsi the task is initially associated with
+user|An opaque user-private pointer used for communication with the lws service thread and private state / data
+task|A pointer to the function that will run in the pool thread
+cleanup|A pointer to a function that will clean up finished or stopped tasks (perhaps freeing user)
+
+Tasks also should have a name, the creation function again provides varargs
+to simplify naming the task with string elements related to who started it
+and why.
+
+#### The task function itself
+
+The task function receives the task user pointer and the task state. The
+possible task states are
+
+State|Meaning
+---|---
+LWS_TP_STATUS_QUEUED|Task is still waiting for a pool thread
+LWS_TP_STATUS_RUNNING|Task is supposed to do its work
+LWS_TP_STATUS_SYNCING|Task is blocked waiting for sync from lws service thread
+LWS_TP_STATUS_STOPPING|Task has been asked to stop but didn't stop yet
+LWS_TP_STATUS_FINISHED|Task has reported it has completed
+LWS_TP_STATUS_STOPPED|Task has aborted
+
+The task function will only be told `LWS_TP_STATUS_RUNNING` or
+`LWS_TP_STATUS_STOPPING` in its status argument... RUNNING means continue with the
+user task and STOPPING means clean up and return `LWS_TP_RETURN_STOPPED`.
+
+If possible every 100ms or so the task should return `LWS_TP_RETURN_CHECKING_IN`
+to allow lws to inform it reasonably quickly that it has been asked to stop
+(eg, because the related wsi has closed), or if it can continue. If not
+possible, it's okay but eg exiting the application may experience delays
+until the running task finishes, and since the wsi may have gone, the work
+is wasted.
+
+The task function may return one of
+
+Return|Meaning
+---|---
+LWS_TP_RETURN_CHECKING_IN|Still wants to run, but confirming nobody asked him to stop. Will be called again immediately with `LWS_TP_STATUS_RUNNING` or `LWS_TP_STATUS_STOPPING`
+LWS_TP_RETURN_SYNC|Task wants to trigger a WRITABLE callback and block until lws service thread restarts it with `lws_threadpool_task_sync()`
+LWS_TP_RETURN_FINISHED|Task has finished, successfully as far as it goes
+LWS_TP_RETURN_STOPPED|Task has finished, aborting in response to a request to stop
+
+The SYNC or CHECKING_IN return may also have a flag `LWS_TP_RETURN_FLAG_OUTLIVE`
+applied to it, which indicates to threadpool that this task wishes to remain
+unstopped after the wsi closes. This is useful in the case where the task
+understands it will take a long time to complete, and wants to return a
+complete status and maybe close the connection, perhaps with a token identifying
+the task. The task can then be monitored separately by using the token.
+
+#### Synchronizing
+
+The task can choose to "SYNC" with the lws service thread, in other words
+cause a WRITABLE callback on the associated wsi in the lws service thread
+context and block itself until it hears back from there via
+`lws_threadpool_task_sync()` to resume the task.
+
+This is typically used when, eg, the task has filled its buffer, or ringbuffer,
+and needs to pause operations until what's done has been sent and some buffer
+space is open again.
+
+In the WRITABLE callback, in lws service thread context, the buffer can be
+sent with `lws_write()` and then `lws_threadpool_task_sync()` to allow the task
+to fill another buffer and continue that way.
+
+If the WRITABLE callback determines that the task should stop, it can just call
+`lws_threadpool_task_sync()` with the second argument as 1, to force the task
+to stop immediately after it resumes.
+
+#### The cleanup function
+
+When a finished task is reaped, or a task that become detached from its initial
+wsi completes or is stopped, it calls the `.cleanup` function defined in the
+task creation args struct to free anything related to the user pointer.
+
+With threadpool, responsibility for freeing allocations used by the task belongs
+strictly with the task, via the `.cleanup` function, once the task has been
+enqueued. That's different from a typical non-threadpool protocol where the
+wsi lifecycle controls deallocation. This reflects the fact that the task
+may outlive the wsi.
+
+#### Protecting against WRITABLE and / or SYNC duplication
+
+Care should be taken than data prepared by the task thread in the user priv
+memory should only be sent once. For example, after sending data from a user
+priv buffer of a given length stored in the priv, zero down the length.
+
+Task execution and the SYNC writable callbacks are mutually exclusive, so there
+is no danger of collision between the task thread and the lws service thread if
+the reason for the callback is a SYNC operation from the task thread.
+
+### Thread overcommit
+
+If the tasks running on the threads are ultimately network-bound for all or some
+of their processing (via the SYNC with the WRITEABLE callback), it's possible
+to overcommit the number of threads in the pool compared to the number of
+threads the processor has in hardware to get better occupancy in the CPU.

+## Information for new role implementers
+
+### Introduction
+
+In lws the "role" is the job the wsi is doing in the system, eg,
+being an http1 or h2, or ws connection, or being a listen socket, etc.
+
+This is different than, eg, a new ws protocol or a different callback
+for an existing role. A new role is needed when you want to add support for
+something completely new, like a completely new wire protocol that
+doesn't use http or ws.
+
+So... what's the point of implementing the protocol inside the lws role framework?
+
+You inherit all the well-maintained lws core functionality around:
+
+ - connection lifecycle sequencing in a valgrind-clean way
+
+ - proxy support, HTTP and Socks5
+
+ - tls support working equally on mbedTLS and OpenSSL and derivatives without any code in the role
+
+ - apis for cert lifecycle management and parsing
+
+ - event loop support working on all the lws event loops (poll, libuv , ev, and event)
+
+ - clean connection tracking and closing even on advanced event loops
+
+ - user code follows the same simple callbacks on wsi
+
+ - multi-vhost support
+
+ - core multithreaded service support with usually no locking requirement on the role code
+
+ - direct compatibility with all other lws roles + protocols in the same event loop
+
+ - compatibility with higher-level stuff like lwsws as the server application
+
+### Code placement
+
+The code specific to that role should live in `./lib/roles/**role name**`
+
+If a role is asymmetic between a client and server side, like http is, it
+should generally be implemented as a single role.
+
+### Allowing control over enabling roles
+
+All roles should add a cmake define `LWS_ROLE_**role name**` and make its build
+dependent on it in CMakeLists.txt. Export the cmakedefine in `./cmake/lws_config.h.in`
+as well so user builds can understand if the role is available in the lws build it is
+trying to bind to.
+
+If the role is disabled in cmake, nothing in its directory is built.
+
+### Role ops struct
+
+The role is defined by `struct lws_role_ops` in `lib/roles/private.h`,
+each role instantiates one of these and fills in the appropriate ops
+callbacks to perform its job. By convention that lives in
+`./lib/roles/**role name**/ops-**role_name**.c`.
+
+### Private role declarations
+
+Truly private declarations for the role can go in the role directory as you like.
+However when the declarations must be accessible to other things in lws build, eg,
+the role adds members to `struct lws` when enabled, they should be in the role
+directory in a file `private.h`.
+
+Search for "bring in role private declarations" in `./lib/roles/private.h
+and add your private role file there following the style used for the other roles,
+eg,
+
+```
+#if defined(LWS_ROLE_WS)
+ #include "roles/ws/private.h"
+#else
+ #define lwsi_role_ws(wsi) (0)
+#endif
+```
+
+If the role is disabled at cmake, nothing from its private.h should be used anywhere.
+
+### Integrating role assets to lws
+
+If your role needs special storage in lws objects, that's no problem. But to keep
+things sane, there are some rules.
+
+ - declare a "container struct" in your private.h for everything, eg, the ws role wants
+ to add storage in lws_vhost for enabled extensions, it declares in its private.h
+
+```
+struct lws_vhost_role_ws {
+#if !defined(LWS_WITHOUT_EXTENSIONS)
+ const struct lws_extension *extensions;
+#endif
+};
+```
+
+ - add your role content in one place in the lws struct, protected by `#if defined(LWS_ROLE_**role name**)`,
+ eg, again for LWS_ROLE_WS
+
+```
+ struct lws_vhost {
+
+...
+
+#if defined(LWS_ROLE_WS)
+ struct lws_vhost_role_ws ws;
+#endif
+
+...
+```
+
+### Adding to lws available roles list
+
+Edit the NULL-terminated array `available_roles` at the top of `./lib/core/context.c` to include
+a pointer to your new role's ops struct, following the style already there.
+
+```
+const struct lws_role_ops * available_roles[] = {
+#if defined(LWS_ROLE_H2)
+ &role_ops_h2,
+#endif
+...
+```
+
+This makes lws aware that your role exists, and it can auto-generate some things like
+ALPN lists, and call your role ops callbacks for things like hooking vhost creation.
+
+### Enabling role adoption
+
+The primary way wsi get bound to a specific role is via the lws adoption api
+`lws_adopt_descriptor_vhost()`. Add flags as necessary in `./include/libwebsockets/lws-adopt.h`
+`enum lws_adoption_type` and follow the existing code in `lws_adopt_descriptor_vhost()`
+to bind a wsi with suitable flags to your role ops.
+
+### Implementation of the role
+
+After that plumbing-in is completed, the role ops you declare are "live" on a wsi
+bound to them via the adoption api.
+
+The core support for wsis in lws has some generic concepts
+
+ - the wsi holds a pointer member `role_ops` that indicates which role ops the
+ wsi is bound to
+
+ - the wsi holds a generic uint32 `wsistate` that contains role flags and wsi state
+
+ - role flags are provided (LWSIFR_CLIENT, LWSIFR_SERVER) to differentiate between
+ client and server connections inside a wsi, along with helpers `lwsi_role_client(wsi)`
+ and `lwsi_role_server(wsi)`.
+
+ - lws provides around 30 generic states for the wsi starting from 'unconnected' through
+ various proxy or tunnel states, to 'established', and then various states shutting
+ down until 'dead socket'. The states have testable flags and helpers to discover if
+ the wsi state is before establishment `lwsi_state_est(wsi)` and if in the state it is
+ in, it can handle pollout `lwsi_state_can_handle_POLLOUT(wsi)`.
+
+ - You set the initial binding, role flags and state using `lws_role_transition()`. Afterwards
+ you can adjust the state using `lwsi_set_state()`.

+# DBUS Role Support
+
+## DBUS-related distro packages
+
+Fedora: dbus-devel
+Debian / Ubuntu: libdbus-1-dev
+
+## Enabling for build at cmake
+
+Fedora example:
+```
+$ cmake .. -DLWS_ROLE_DBUS=1 -DLWS_DBUS_INCLUDE2="/usr/lib64/dbus-1.0/include"
+```
+
+Ubuntu example:
+```
+$ cmake .. -DLWS_ROLE_DBUS=1 -DLWS_DBUS_INCLUDE2="/usr/lib/x86_64-linux-gnu/dbus-1.0/include"
+```
+
+Dbus requires two include paths, which you can force by setting `LWS_DBUS_INCLUDE1`
+and `LWS_DBUS_INCLUDE2`. Although INCLUDE1 is usually guessable, both can be
+forced to allow cross-build.
+
+If these are not forced, then lws cmake will try to check some popular places,
+for `LWS_DBUS_INCLUDE1`, on both Fedora and Debian / Ubuntu, this is
+`/usr/include/dbus-1.0`... if the directory exists, it is used.
+
+For `LWS_DBUS_INCLUDE2`, it is the arch-specific dbus header which may be
+packaged separately than the main dbus headers. On Fedora, this is in
+`/usr/lib[64]/dbus-1.0/include`... if not given externally, lws cmake will
+try `/usr/lib64/dbus-1.0/include`. On Debian / Ubuntu, the package installs
+it in an arch-specific dir like `/usr/lib/x86_64-linux-gnu/dbus-1.0/include`,
+you should force the path.
+
+The library path is usually \[lib\] "dbus-1", but this can also be forced if
+you want to build cross or use a special build, via `LWS_DBUS_LIB`.
+
+## Building against local dbus build
+
+If you built your own local dbus and installed it in /usr/local, then
+this is the incantation to direct lws to use the local version of dbus:
+
+```
+cmake .. -DLWS_ROLE_DBUS=1 -DLWS_DBUS_INCLUDE1="/usr/local/include/dbus-1.0" -DLWS_DBUS_INCLUDE2="/usr/local/lib/dbus-1.0/include" -DLWS_DBUS_LIB="/usr/local/lib/libdbus-1.so"
+```
+
+You'll also need to give the loader a helping hand to do what you want if
+there's a perfectly good dbus lib already in `/usr/lib[64]` using `LD_PRELOAD`
+like this
+
+```
+LD_PRELOAD=/usr/local/lib/libdbus-1.so.3.24.0 myapp
+```
+
+## Lws dbus api exports
+
+Because of the irregular situation with libdbus includes, if lws exports the
+dbus helpers, which use dbus types, as usual from `#include <libwebsockets.h>`
+then if lws was compiled with dbus role support it forces all users to take
+care about the dbus include path mess whether they use dbus themselves or not.
+
+For that reason, if you need access to the lws dbus apis, you must explicitly
+include them by
+
+```
+#include <libwebsockets/lws-dbus.h>
+```
+
+This includes `<dbus/dbus.h>` and so requires the include paths set up. But
+otherwise non-dbus users that don't include `libwebsockets/lws-dbus.h` don't
+have to care about it.
+

+HTTP compression
+----------------
+
+This directory contains generic compression transforms that can be applied to
+specifically HTTP content streams, after the header, be it h1 or h2.
+
+The compression transforms expose an "ops" type struct and a compressor name
+as used by `content-encoding`... the ops struct definition can be found in
+./private.h.
+
+Because the compression transform depends on being able to send on its output
+before it can process new input, the transform adds a new kind of buflist
+`wsi->buflist_comp` that represents pre-compression transform data
+("input data" from the perspective of the compression transform) that was
+delivered to be processed but couldn't be accepted.
+
+Currently, zlib 'deflate' and brotli 'br' are supported on the server side.

-##Libwebsockets API introduction
-
-Libwebsockets covers a lot of interesting features for people making embedded servers or clients
-
- - http(s) serving and client operation
- - ws(s) serving and client operation
- - http(s) apis for file transfer and upload
- - http POST form handling (including multipart)
- - cookie-based sessions
- - account management (including registration, email verification, lost pw etc)
- - strong ssl PFS support (A+ on SSLlabs test)
-
-You can browse by api category <a href="modules.html">here</a>
-
-A collection of READMEs for build, coding, lwsws etc are <a href="pages.html">here</a>

+## FAQ
+
+### Getting started
+
+Build and install lws itself first (note that after installing lws on \*nix, you need to run `ldconfig` one time so the OS can learn about the new library. Lws installs in `/usr/local` by default, Debian / Ubuntu ldconfig knows to look there already, but Fedora / CentOS need you to add the line `/usr/local/lib` to `/etc/ld.so.conf` and run ldconfig)
+
+Then start with the simplest:
+
+`http-server/minimal-http-server`
+
+### Why are most of the sources split into a main C file file and a protocol file?
+
+Lws supports three ways to implement the protocol callback code:
+
+ - you can just add it all in the same source file
+
+ - you can separate it as these examples do, and #include it
+ into the main sources
+
+ - you can build it as a standalone plugin that is discovered
+ and loaded at runtime.
+
+The way these examples are structured, you can easily also build
+the protocol callback as a plugin just with a different
+CMakeLists.txt... see https://github.com/warmcat/libwebsockets/tree/master/plugin-standalone
+for an example.
+
+### Why would we want the protocol as a plugin?
+
+You will notice a lot of the main C code is the same boilerplate
+repeated for each example. The actual interesting part is in
+the protocol callback only.
+
+Lws provides (-DLWS_WITH_LWSWS=1) a generic lightweight server app called 'lwsws' that
+can be configured by JSON. Combined with your protocol as a plugin,
+it means you don't actually have to make a special server "app"
+part, you can just use lwsws and pass per-vhost configuration
+from JSON into your protocol. (Of course in some cases you have
+an existing app you are bolting lws on to, then you don't care
+about this for that particular case).
+
+Because lwsws has no dependency on whatever your plugin does, it
+can mix and match different protocols randomly without needing any code
+changes. It reduces the size of the task to just writing the
+code you care about in your protocol handler, and nothing else to write
+or maintain.
+
+Lwsws supports advanced features like reload, where it starts a new server
+instance with changed config or different plugins, while keeping the old
+instance around until the last connection to it closes.
+
+### I get why there is a pss, but why is there a vhd?
+
+The pss is instantiated per-connection. But there are almost always
+other variables that have a lifetime longer than a single connection.
+
+You could make these variables "filescope" one-time globals, but that
+means your protocol cannot instantiate multiple times.
+
+Lws supports vhosts (virtual hosts), for example both https://warmcat.com
+and https://libwebsockets are running on the same lwsws instance on the
+same server and same IP... each of these is a separate vhost.
+
+Your protocol may be enabled on multiple vhosts, each of these vhosts
+provides a different vhd specific to the protocol instance on that
+vhost. For example many of the samples keep a linked-list head to
+a list of live pss in the vhd... that means it's cleanly a list of
+pss opened **on that vhost**. If another vhost has the protocol
+enabled, connections to that will point to a different vhd, and the
+linked-list head on that vhd will only list connections to his vhost.
+
+The example "ws-server/minimal-ws-server-threads" demonstrates how to deliver
+external configuration data to a specific vhost + protocol
+combination using code. In lwsws, this is simply a matter of setting
+the desired JSON config.

+Chapitre I\r
+\r
+Monsieur Myriel\r
+\r
+\r
+En 1815, M. Charles-François-Bienvenu Myriel était évêque de Digne.\r
+C'était un vieillard d'environ soixante-quinze ans; il occupait le siège\r
+de Digne depuis 1806.\r
+\r
+Quoique ce détail ne touche en aucune manière au fond même de ce que\r
+nous avons à raconter, il n'est peut-être pas inutile, ne fût-ce que\r
+pour être exact en tout, d'indiquer ici les bruits et les propos qui\r
+avaient couru sur son compte au moment où il était arrivé dans le\r
+diocèse. Vrai ou faux, ce qu'on dit des hommes tient souvent autant de\r
+place dans leur vie et surtout dans leur destinée que ce qu'ils font. M.\r
+Myriel était fils d'un conseiller au parlement d'Aix; noblesse de robe.\r
+On contait de lui que son père, le réservant pour hériter de sa charge,\r
+l'avait marié de fort bonne heure, à dix-huit ou vingt ans, suivant un\r
+usage assez répandu dans les familles parlementaires. Charles Myriel,\r
+nonobstant ce mariage, avait, disait-on, beaucoup fait parler de lui. Il\r
+était bien fait de sa personne, quoique d'assez petite taille, élégant,\r
+gracieux, spirituel; toute la première partie de sa vie avait été donnée\r
+au monde et aux galanteries. La révolution survint, les événements se\r
+précipitèrent, les familles parlementaires décimées, chassées, traquées,\r
+se dispersèrent. M. Charles Myriel, dès les premiers jours de la\r
+révolution, émigra en Italie. Sa femme y mourut d'une maladie de\r
+poitrine dont elle était atteinte depuis longtemps. Ils n'avaient point\r
+d'enfants. Que se passa-t-il ensuite dans la destinée de M. Myriel?\r
+L'écroulement de l'ancienne société française, la chute de sa propre\r
+famille, les tragiques spectacles de 93, plus effrayants encore\r
+peut-être pour les émigrés qui les voyaient de loin avec le\r
+grossissement de l'épouvante, firent-ils germer en lui des idées de\r
+renoncement et de solitude? Fut-il, au milieu d'une de ces distractions\r
+et de ces affections qui occupaient sa vie, subitement atteint d'un de\r
+ces coups mystérieux et terribles qui viennent quelquefois renverser, en\r
+le frappant au coeur, l'homme que les catastrophes publiques\r
+n'ébranleraient pas en le frappant dans son existence et dans sa\r
+fortune? Nul n'aurait pu le dire; tout ce qu'on savait, c'est que,\r
+lorsqu'il revint d'Italie, il était prêtre.\r
+\r
+En 1804, M. Myriel était curé de Brignolles. Il était déjà vieux, et\r
+vivait dans une retraite profonde.\r
+\r
+Vers l'époque du couronnement, une petite affaire de sa cure, on ne sait\r
+plus trop quoi, l'amena à Paris. Entre autres personnes puissantes, il\r
+alla solliciter pour ses paroissiens M. le cardinal Fesch. Un jour que\r
+l'empereur était venu faire visite à son oncle, le digne curé, qui\r
+attendait dans l'antichambre, se trouva sur le passage de sa majesté.\r
+Napoléon, se voyant regardé avec une certaine curiosité par ce\r
+vieillard, se retourna, et dit brusquement:\r
+\r
+--Quel est ce bonhomme qui me regarde?\r
+\r
+--Sire, dit M. Myriel, vous regardez un bonhomme, et moi je regarde un\r
+grand homme. Chacun de nous peut profiter.\r
+\r
+L'empereur, le soir même, demanda au cardinal le nom de ce curé, et\r
+quelque temps après M. Myriel fut tout surpris d'apprendre qu'il était\r
+nommé évêque de Digne.\r
+\r
+Qu'y avait-il de vrai, du reste, dans les récits qu'on faisait sur la\r
+première partie de la vie de M. Myriel? Personne ne le savait. Peu de\r
+familles avaient connu la famille Myriel avant la révolution.\r
+\r
+M. Myriel devait subir le sort de tout nouveau venu dans une petite\r
+ville où il y a beaucoup de bouches qui parlent et fort peu de têtes qui\r
+pensent. Il devait le subir, quoiqu'il fût évêque et parce qu'il était\r
+évêque. Mais, après tout, les propos auxquels on mêlait son nom\r
+n'étaient peut-être que des propos; du bruit, des mots, des paroles;\r
+moins que des paroles, des _palabres_, comme dit l'énergique langue du\r
+midi.\r
+\r
+Quoi qu'il en fût, après neuf ans d'épiscopat et de résidence à Digne,\r
+tous ces racontages, sujets de conversation qui occupent dans le premier\r
+moment les petites villes et les petites gens, étaient tombés dans un\r
+oubli profond. Personne n'eût osé en parler, personne n'eût même osé\r
+s'en souvenir.\r
+\r
+M. Myriel était arrivé à Digne accompagné d'une vieille fille,\r
+mademoiselle Baptistine, qui était sa soeur et qui avait dix ans de\r
+moins que lui.\r
+\r
+Ils avaient pour tout domestique une servante du même âge que\r
+mademoiselle Baptistine, et appelée madame Magloire, laquelle, après\r
+avoir été _la servante de M. le Curé_, prenait maintenant le double\r
+titre de femme de chambre de mademoiselle et femme de charge de\r
+monseigneur.\r
+\r
+Mademoiselle Baptistine était une personne longue, pâle, mince, douce;\r
+elle réalisait l'idéal de ce qu'exprime le mot «respectable»; car il\r
+semble qu'il soit nécessaire qu'une femme soit mère pour être vénérable.\r
+Elle n'avait jamais été jolie; toute sa vie, qui n'avait été qu'une\r
+suite de saintes oeuvres, avait fini par mettre sur elle une sorte de\r
+blancheur et de clarté; et, en vieillissant, elle avait gagné ce qu'on\r
+pourrait appeler la beauté de la bonté. Ce qui avait été de la maigreur\r
+dans sa jeunesse était devenu, dans sa maturité, de la transparence; et\r
+cette diaphanéité laissait voir l'ange. C'était une âme plus encore que\r
+ce n'était une vierge. Sa personne semblait faite d'ombre; à peine assez\r
+de corps pour qu'il y eût là un sexe; un peu de matière contenant une\r
+lueur; de grands yeux toujours baissés; un prétexte pour qu'une âme\r
+reste sur la terre.\r
+\r
+Madame Magloire était une petite vieille, blanche, grasse, replète,\r
+affairée, toujours haletante, à cause de son activité d'abord, ensuite à\r
+cause d'un asthme.\r
+\r
+À son arrivée, on installa M. Myriel en son palais épiscopal avec les\r
+honneurs voulus par les décrets impériaux qui classent l'évêque\r
+immédiatement après le maréchal de camp. Le maire et le président lui\r
+firent la première visite, et lui de son côté fit la première visite au\r
+général et au préfet.\r
+\r
+L'installation terminée, la ville attendit son évêque à l'oeuvre.\r
+\r
+\r
+\r
+\r
+Chapitre II\r
+\r
+Monsieur Myriel devient monseigneur Bienvenu\r
+\r
+\r
+Le palais épiscopal de Digne était attenant à l'hôpital.\r
+\r
+Le palais épiscopal était un vaste et bel hôtel bâti en pierre au\r
+commencement du siècle dernier par monseigneur Henri Puget, docteur en\r
+théologie de la faculté de Paris, abbé de Simore, lequel était évêque de\r
+Digne en 1712. Ce palais était un vrai logis seigneurial. Tout y avait\r
+grand air, les appartements de l'évêque, les salons, les chambres, la\r
+cour d'honneur, fort large, avec promenoirs à arcades, selon l'ancienne\r
+mode florentine, les jardins plantés de magnifiques arbres. Dans la\r
+salle à manger, longue et superbe galerie qui était au rez-de-chaussée\r
+et s'ouvrait sur les jardins, monseigneur Henri Puget avait donné à\r
+manger en cérémonie le 29 juillet 1714 à messeigneurs Charles Brûlart de\r
+Genlis, archevêque-prince d'Embrun, Antoine de Mesgrigny, capucin,\r
+évêque de Grasse, Philippe de Vendôme, grand prieur de France, abbé de\r
+Saint-Honoré de Lérins, François de Berton de Grillon, évêque-baron de\r
+Vence, César de Sabran de Forcalquier, évêque-seigneur de Glandève, et\r
+Jean Soanen, prêtre de l'oratoire, prédicateur ordinaire du roi,\r
+évêque-seigneur de Senez. Les portraits de ces sept révérends\r
+personnages décoraient cette salle, et cette date mémorable, 29 juillet\r
+1714, y était gravée en lettres d'or sur une table de marbre blanc.\r
+\r
+L'hôpital était une maison étroite et basse à un seul étage avec un\r
+petit jardin. Trois jours après son arrivée, l'évêque visita l'hôpital.\r
+La visite terminée, il fit prier le directeur de vouloir bien venir\r
+jusque chez lui.\r
+\r
+--Monsieur le directeur de l'hôpital, lui dit-il, combien en ce moment\r
+avez-vous de malades?\r
+\r
+--Vingt-six, monseigneur.\r
+\r
+--C'est ce que j'avais compté, dit l'évêque.\r
+\r
+--Les lits, reprit le directeur, sont bien serrés les uns contre les\r
+autres.\r
+\r
+--C'est ce que j'avais remarqué.\r
+\r
+--Les salles ne sont que des chambres, et l'air s'y renouvelle\r
+difficilement.\r
+\r
+--C'est ce qui me semble.\r
+\r
+--Et puis, quand il y a un rayon de soleil, le jardin est bien petit\r
+pour les convalescents.\r
+\r
+--C'est ce que je me disais.\r
+\r
+--Dans les épidémies, nous avons eu cette année le typhus, nous avons eu\r
+une suette militaire il y a deux ans, cent malades quelquefois; nous ne\r
+savons que faire.\r
+\r
+--C'est la pensée qui m'était venue.\r
+\r
+--Que voulez-vous, monseigneur? dit le directeur, il faut se résigner.\r
+\r
+Cette conversation avait lieu dans la salle à manger-galerie du\r
+rez-de-chaussée. L'évêque garda un moment le silence, puis il se tourna\r
+brusquement vers le directeur de l'hôpital:\r
+\r
+--Monsieur, dit-il, combien pensez-vous qu'il tiendrait de lits rien que\r
+dans cette salle?\r
+\r
+--La salle à manger de monseigneur! s'écria le directeur stupéfait.\r
+\r
+L'évêque parcourait la salle du regard et semblait y faire avec les yeux\r
+des mesures et des calculs.\r
+\r
+--Il y tiendrait bien vingt lits! dit-il, comme se parlant à lui-même.\r
+\r
+Puis élevant la voix:\r
+\r
+--Tenez, monsieur le directeur de l'hôpital, je vais vous dire. Il y a\r
+évidemment une erreur. Vous êtes vingt-six personnes dans cinq ou six\r
+petites chambres. Nous sommes trois ici, et nous avons place pour\r
+soixante. Il y a erreur, je vous dis. Vous avez mon logis, et j'ai le\r
+vôtre. Rendez-moi ma maison. C'est ici chez vous.\r
+\r
+Le lendemain, les vingt-six pauvres étaient installés dans le palais de\r
+l'évêque et l'évêque était à l'hôpital.\r
+\r
+M. Myriel n'avait point de bien, sa famille ayant été ruinée par la\r
+révolution. Sa soeur touchait une rente viagère de cinq cents francs\r
+qui, au presbytère, suffisait à sa dépense personnelle. M. Myriel\r
+recevait de l'état comme évêque un traitement de quinze mille francs. Le\r
+jour même où il vint se loger dans la maison de l'hôpital, M. Myriel\r
+détermina l'emploi de cette somme une fois pour toutes de la manière\r
+suivante. Nous transcrivons ici une note écrite de sa main.\r
+\r
+_Note pour régler les dépenses de ma maison._\r
+\r
+_Pour le petit séminaire: quinze cents livres_\r
+_Congrégation de la mission: cent livres_\r
+_Pour les lazaristes de Montdidier: cent livres_\r
+_Séminaire des missions étrangères à Paris: deux cents livres_\r
+_Congrégation du Saint-Esprit: cent cinquante livres_\r
+_Établissements religieux de la Terre-Sainte: cent livres_\r
+_Sociétés de charité maternelle: trois cents livres_\r
+_En sus, pour celle d'Arles: cinquante livres_\r
+_OEuvre pour l'amélioration des prisons: quatre cents livres_\r
+_OEuvre pour le soulagement et la délivrance des prisonniers: cinq cents\r
+livres_\r
+_Pour libérer des pères de famille prisonniers pour dettes: mille livres_\r
+_Supplément au traitement des pauvres maîtres d'école du diocèse: deux\r
+mille livres_\r
+_Grenier d'abondance des Hautes-Alpes: cent livres_\r
+_Congrégation des dames de Digne, de Manosque et de Sisteron,\r
+pour l'enseignement gratuit des filles indigentes: quinze cents livres_\r
+_Pour les pauvres: six mille livres_\r
+_Ma dépense personnelle: mille livres_\r
+\r
+Total: _quinze mille livres_\r
+\r
+Pendant tout le temps qu'il occupa le siège de Digne, M. Myriel ne\r
+changea presque rien à cet arrangement. Il appelait cela, comme on voit,\r
+_avoir réglé les dépenses de sa maison_.\r
+\r
+Cet arrangement fut accepté avec une soumission absolue par mademoiselle\r
+Baptistine. Pour cette sainte fille, M. de Digne était tout à la fois\r
+son frère et son évêque, son ami selon la nature et son supérieur selon\r
+l'église. Elle l'aimait et elle le vénérait tout simplement. Quand il\r
+parlait, elle s'inclinait; quand il agissait, elle adhérait. La servante\r
+seule, madame Magloire, murmura un peu. M. l'évêque, on l'a pu\r
+remarquer, ne s'était réservé que mille livres, ce qui, joint à la\r
+pension de mademoiselle Baptistine, faisait quinze cents francs par an.\r
+Avec ces quinze cents francs, ces deux vieilles femmes et ce vieillard\r
+vivaient.\r
+\r
+Et quand un curé de village venait à Digne, M. l'évêque trouvait encore\r
+moyen de le traiter, grâce à la sévère économie de madame Magloire et à\r
+l'intelligente administration de mademoiselle Baptistine.\r
+\r
+Un jour--il était à Digne depuis environ trois mois--l'évêque dit:\r
+\r
+--Avec tout cela je suis bien gêné!\r
+\r
+--Je le crois bien! s'écria madame Magloire, Monseigneur n'a seulement\r
+pas réclamé la rente que le département lui doit pour ses frais de\r
+carrosse en ville et de tournées dans le diocèse. Pour les évêques\r
+d'autrefois c'était l'usage.\r
+\r
+--Tiens! dit l'évêque, vous avez raison, madame Magloire.\r
+\r
+Il fit sa réclamation.\r
+\r
+Quelque temps après, le conseil général, prenant cette demande en\r
+considération, lui vota une somme annuelle de trois mille francs, sous\r
+cette rubrique: _Allocation à M. l'évêque pour frais de carrosse, frais\r
+de poste et frais de tournées pastorales_.\r
+\r
+Cela fit beaucoup crier la bourgeoisie locale, et, à cette occasion, un\r
+sénateur de l'empire, ancien membre du conseil des cinq-cents favorable\r
+au dix-huit brumaire et pourvu près de la ville de Digne d'une\r
+sénatorerie magnifique, écrivit au ministre des cultes, M. Bigot de\r
+Préameneu, un petit billet irrité et confidentiel dont nous extrayons\r
+ces lignes authentiques:\r
+\r
+«--Des frais de carrosse? pourquoi faire dans une ville de moins de\r
+quatre mille habitants? Des frais de poste et de tournées? à quoi bon\r
+ces tournées d'abord? ensuite comment courir la poste dans un pays de\r
+montagnes? Il n'y a pas de routes. On ne va qu'à cheval. Le pont même de\r
+la Durance à Château-Arnoux peut à peine porter des charrettes à boeufs.\r
+Ces prêtres sont tous ainsi. Avides et avares. Celui-ci a fait le bon\r
+apôtre en arrivant. Maintenant il fait comme les autres. Il lui faut\r
+carrosse et chaise de poste. Il lui faut du luxe comme aux anciens\r
+évêques. Oh! toute cette prêtraille! Monsieur le comte, les choses\r
+n'iront bien que lorsque l'empereur nous aura délivrés des calotins. À\r
+bas le pape! (les affaires se brouillaient avec Rome). Quant à moi, je\r
+suis pour César tout seul. Etc., etc.»\r
+\r
+La chose, en revanche, réjouit fort madame Magloire.\r
+\r
+--Bon, dit-elle à mademoiselle Baptistine, Monseigneur a commencé par\r
+les autres, mais il a bien fallu qu'il finît par lui-même. Il a réglé\r
+toutes ses charités. Voilà trois mille livres pour nous. Enfin!\r
+\r
+Le soir même, l'évêque écrivit et remit à sa soeur une note ainsi\r
+conçue:\r
+\r
+_Frais de carrosse et de tournées._\r
+\r
+_Pour donner du bouillon de viande aux malades de l'hôpital: quinze\r
+cents livres_\r
+_Pour la société de charité maternelle d'Aix: deux cent cinquante livres_\r
+_Pour la société de charité maternelle de Draguignan: deux cent cinquante\r
+livres_\r
+_Pour les enfants trouvés: cinq cents livres_\r
+_Pour les orphelins: cinq cents livres_\r
+\r
+Total: _trois mille livres_\r
+\r
+Tel était le budget de M. Myriel.\r
+\r
+Quant au casuel épiscopal, rachats de bans, dispenses, ondoiements,\r
+prédications, bénédictions d'églises ou de chapelles, mariages, etc.,\r
+l'évêque le percevait sur les riches avec d'autant plus d'âpreté qu'il\r
+le donnait aux pauvres.\r
+\r
+Au bout de peu de temps, les offrandes d'argent affluèrent. Ceux qui ont\r
+et ceux qui manquent frappaient à la porte de M. Myriel, les uns venant\r
+chercher l'aumône que les autres venaient y déposer. L'évêque, en moins\r
+d'un an, devint le trésorier de tous les bienfaits et le caissier de\r
+toutes les détresses. Des sommes considérables passaient par ses mains;\r
+mais rien ne put faire qu'il changeât quelque chose à son genre de vie\r
+et qu'il ajoutât le moindre superflu à son nécessaire.\r
+\r
+Loin de là. Comme il y a toujours encore plus de misère en bas que de\r
+fraternité en haut, tout était donné, pour ainsi dire, avant d'être\r
+reçu; c'était comme de l'eau sur une terre sèche; il avait beau recevoir\r
+de l'argent, il n'en avait jamais. Alors il se dépouillait.\r
+\r
+L'usage étant que les évêques énoncent leurs noms de baptême en tête de\r
+leurs mandements et de leurs lettres pastorales, les pauvres gens du\r
+pays avaient choisi, avec une sorte d'instinct affectueux, dans les noms\r
+et prénoms de l'évêque, celui qui leur présentait un sens, et ils ne\r
+l'appelaient que monseigneur Bienvenu. Nous ferons comme eux, et nous le\r
+nommerons ainsi dans l'occasion. Du reste, cette appellation lui\r
+plaisait.\r
+\r
+--J'aime ce nom-là, disait-il. Bienvenu corrige monseigneur.\r
+\r
+Nous ne prétendons pas que le portrait que nous faisons ici soit\r
+vraisemblable; nous nous bornons à dire qu'il est ressemblant.\r
+\r
+\r
+\r
+\r
+Chapitre III\r
+\r
+À bon évêque dur évêché\r
+\r
+\r
+M. l'évêque, pour avoir converti son carrosse en aumônes, n'en faisait\r
+pas moins ses tournées. C'est un diocèse fatigant que celui de Digne. Il\r
+a fort peu de plaines, beaucoup de montagnes, presque pas de routes, on\r
+l'a vu tout à l'heure; trente-deux cures, quarante et un vicariats et\r
+deux cent quatre-vingt-cinq succursales. Visiter tout cela, c'est une\r
+affaire. M. l'évêque en venait à bout. Il allait à pied quand c'était\r
+dans le voisinage, en carriole dans la plaine, en cacolet dans la\r
+montagne. Les deux vieilles femmes l'accompagnaient. Quand le trajet\r
+était trop pénible pour elles, il allait seul.\r
+\r
+Un jour, il arriva à Senez, qui est une ancienne ville épiscopale, monté\r
+sur un âne. Sa bourse, fort à sec dans ce moment, ne lui avait pas\r
+permis d'autre équipage. Le maire de la ville vint le recevoir à la\r
+porte de l'évêché et le regardait descendre de son âne avec des yeux\r
+scandalisés. Quelques bourgeois riaient autour de lui.\r
+\r
+--Monsieur le maire, dit l'évêque, et messieurs les bourgeois, je vois\r
+ce qui vous scandalise; vous trouvez que c'est bien de l'orgueil à un\r
+pauvre prêtre de monter une monture qui a été celle de Jésus-Christ. Je\r
+l'ai fait par nécessité, je vous assure, non par vanité.\r
+\r
+Dans ses tournées, il était indulgent et doux, et prêchait moins qu'il\r
+ne causait. Il ne mettait aucune vertu sur un plateau inaccessible. Il\r
+n'allait jamais chercher bien loin ses raisonnements et ses modèles.\r
+Aux habitants d'un pays il citait l'exemple du pays voisin. Dans les\r
+cantons où l'on était dur pour les nécessiteux, il disait:\r
+\r
+--Voyez les gens de Briançon. Ils ont donné aux indigents, aux veuves et\r
+aux orphelins le droit de faire faucher leurs prairies trois jours avant\r
+tous les autres. Ils leur rebâtissent gratuitement leurs maisons quand\r
+elles sont en ruines. Aussi est-ce un pays béni de Dieu. Durant tout un\r
+siècle de cent ans, il n'y a pas eu un meurtrier.\r
+\r
+Dans les villages âpres au gain et à la moisson, il disait:\r
+\r
+--Voyez ceux d'Embrun. Si un père de famille, au temps de la récolte, a\r
+ses fils au service à l'armée et ses filles en service à la ville, et\r
+qu'il soit malade et empêché, le curé le recommande au prône; et le\r
+dimanche, après la messe, tous les gens du village, hommes, femmes,\r
+enfants, vont dans le champ du pauvre homme lui faire sa moisson, et lui\r
+rapportent paille et grain dans son grenier.\r
+\r
+Aux familles divisées par des questions d'argent et d'héritage, il\r
+disait:\r
+\r
+--Voyez les montagnards de Devoluy, pays si sauvage qu'on n'y entend pas\r
+le rossignol une fois en cinquante ans. Eh bien, quand le père meurt\r
+dans une famille, les garçons s'en vont chercher fortune, et laissent le\r
+bien aux filles, afin qu'elles puissent trouver des maris.\r
+\r
+Aux cantons qui ont le goût des procès et où les fermiers se ruinent en\r
+papier timbré, il disait:\r
+\r
+--Voyez ces bons paysans de la vallée de Queyras. Ils sont là trois\r
+mille âmes. Mon Dieu! c'est comme une petite république. On n'y connaît\r
+ni le juge, ni l'huissier. Le maire fait tout. Il répartit l'impôt, taxe\r
+chacun en conscience, juge les querelles gratis, partage les patrimoines\r
+sans honoraires, rend des sentences sans frais; et on lui obéit, parce\r
+que c'est un homme juste parmi des hommes simples.\r
+\r
+Aux villages où il ne trouvait pas de maître d'école, il citait encore\r
+ceux de Queyras:\r
+\r
+--Savez-vous comment ils font? disait-il. Comme un petit pays de douze\r
+ou quinze feux ne peut pas toujours nourrir un magister, ils ont des\r
+maîtres d'école payés par toute la vallée qui parcourent les villages,\r
+passant huit jours dans celui-ci, dix dans celui-là, et enseignant. Ces\r
+magisters vont aux foires, où je les ai vus. On les reconnaît à des\r
+plumes à écrire qu'ils portent dans la ganse de leur chapeau. Ceux qui\r
+n'enseignent qu'à lire ont une plume, ceux qui enseignent la lecture et\r
+le calcul ont deux plumes; ceux qui enseignent la lecture, le calcul et\r
+le latin ont trois plumes. Ceux-là sont de grands savants. Mais quelle\r
+honte d'être ignorants! Faites comme les gens de Queyras.\r
+\r
+Il parlait ainsi, gravement et paternellement, à défaut d'exemples\r
+inventant des paraboles, allant droit au but, avec peu de phrases et\r
+beaucoup d'images, ce qui était l'éloquence même de Jésus-Christ,\r
+convaincu et persuadant.\r
+\r
+\r
+\r
+\r
+Chapitre IV\r
+\r
+Les oeuvres semblables aux paroles\r
+\r
+\r
+Sa conversation était affable et gaie. Il se mettait à la portée des\r
+deux vieilles femmes qui passaient leur vie près de lui; quand il riait,\r
+c'était le rire d'un écolier.\r
+\r
+Madame Magloire l'appelait volontiers _Votre Grandeur_. Un jour, il se\r
+leva de son fauteuil et alla à sa bibliothèque chercher un livre. Ce\r
+livre était sur un des rayons d'en haut. Comme l'évêque était d'assez\r
+petite taille, il ne put y atteindre.\r
+\r
+--Madame Magloire, dit-il, apportez-moi une chaise. Ma grandeur ne va\r
+pas jusqu'à cette planche.\r
+\r
+Une de ses parentes éloignées, madame la comtesse de Lô, laissait\r
+rarement échapper une occasion d'énumérer en sa présence ce qu'elle\r
+appelait «les espérances» de ses trois fils. Elle avait plusieurs\r
+ascendants fort vieux et proches de la mort dont ses fils étaient\r
+naturellement les héritiers. Le plus jeune des trois avait à recueillir\r
+d'une grand'tante cent bonnes mille livres de rentes; le deuxième était\r
+substitué au titre de duc de son oncle; l'aîné devait succéder à la\r
+pairie de son aïeul. L'évêque écoutait habituellement en silence ces\r
+innocents et pardonnables étalages maternels. Une fois pourtant, il\r
+paraissait plus rêveur que de coutume, tandis que madame de Lô\r
+renouvelait le détail de toutes ces successions et de toutes ces\r
+«espérances». Elle s'interrompit avec quelque impatience:\r
+\r
+--Mon Dieu, mon cousin! mais à quoi songez-vous donc?\r
+\r
+--Je songe, dit l'évêque, à quelque chose de singulier qui est, je\r
+crois, dans saint Augustin: «Mettez votre espérance dans celui auquel on\r
+ne succède point.»\r
+\r
+Une autre fois, recevant une lettre de faire-part du décès d'un\r
+gentilhomme du pays, où s'étalaient en une longue page, outre les\r
+dignités du défunt, toutes les qualifications féodales et nobiliaires de\r
+tous ses parents:\r
+\r
+--Quel bon dos a la mort! s'écria-t-il. Quelle admirable charge de\r
+titres on lui fait allègrement porter, et comme il faut que les hommes\r
+aient de l'esprit pour employer ainsi la tombe à la vanité!\r
+\r
+Il avait dans l'occasion une raillerie douce qui contenait presque\r
+toujours un sens sérieux. Pendant un carême, un jeune vicaire vint à\r
+Digne et prêcha dans la cathédrale. Il fut assez éloquent. Le sujet de\r
+son sermon était la charité. Il invita les riches à donner aux\r
+indigents, afin d'éviter l'enfer qu'il peignit le plus effroyable qu'il\r
+put et de gagner le paradis qu'il fit désirable et charmant. Il y avait\r
+dans l'auditoire un riche marchand retiré, un peu usurier, nommé M.\r
+Géborand, lequel avait gagné un demi-million à fabriquer de gros draps,\r
+des serges, des cadis et des gasquets. De sa vie M. Géborand n'avait\r
+fait l'aumône à un malheureux. À partir de ce sermon, on remarqua qu'il\r
+donnait tous les dimanches un sou aux vieilles mendiantes du portail de\r
+la cathédrale. Elles étaient six à se partager cela. Un jour, l'évêque\r
+le vit faisant sa charité et dit à sa soeur avec un sourire:\r
+\r
+--Voilà monsieur Géborand qui achète pour un sou de paradis.\r
+\r
+Quand il s'agissait de charité, il ne se rebutait pas, même devant un\r
+refus, et il trouvait alors des mots qui faisaient réfléchir. Une fois,\r
+il quêtait pour les pauvres dans un salon de la ville. Il y avait là le\r
+marquis de Champtercier, vieux, riche, avare, lequel trouvait moyen\r
+d'être tout ensemble ultra-royaliste et ultra-voltairien. Cette variété\r
+a existé. L'évêque, arrivé à lui, lui toucha le bras.\r
+\r
+--Monsieur le marquis, il faut que vous me donniez quelque chose.\r
+\r
+Le marquis se retourna et répondit sèchement:\r
+\r
+--Monseigneur, j'ai mes pauvres.\r
+\r
+--Donnez-les-moi, dit l'évêque.\r
+\r
+Un jour, dans la cathédrale, il fit ce sermon.\r
+\r
+«Mes très chers frères, mes bons amis, il y a en France treize cent\r
+vingt mille maisons de paysans qui n'ont que trois ouvertures, dix-huit\r
+cent dix-sept mille qui ont deux ouvertures, la porte et une fenêtre, et\r
+enfin trois cent quarante-six mille cabanes qui n'ont qu'une ouverture,\r
+la porte. Et cela, à cause d'une chose qu'on appelle l'impôt des portes\r
+et fenêtres. Mettez-moi de pauvres familles, des vieilles femmes, des\r
+petits enfants, dans ces logis-là, et voyez les fièvres et les maladies.\r
+Hélas! Dieu donne l'air aux hommes, la loi le leur vend. Je n'accuse pas\r
+la loi, mais je bénis Dieu. Dans l'Isère, dans le Var, dans les deux\r
+Alpes, les hautes et les basses, les paysans n'ont pas même de\r
+brouettes, ils transportent les engrais à dos d'hommes; ils n'ont pas de\r
+chandelles, et ils brûlent des bâtons résineux et des bouts de corde\r
+trempés dans la poix résine. C'est comme cela dans tout le pays haut du\r
+Dauphiné. Ils font le pain pour six mois, ils le font cuire avec de la\r
+bouse de vache séchée. L'hiver, ils cassent ce pain à coups de hache et\r
+ils le font tremper dans l'eau vingt-quatre heures pour pouvoir le\r
+manger.--Mes frères, ayez pitié! voyez comme on souffre autour de vous.»\r
+\r
+Né provençal, il s'était facilement familiarisé avec tous les patois du\r
+midi. Il disait: «_Eh bé! moussu, sès sagé?_» comme dans le bas\r
+Languedoc. «_Onté anaras passa?_» comme dans les basses Alpes. «_Puerte\r
+un bouen moutou embe un bouen froumage grase_», comme dans le haut\r
+Dauphiné. Ceci plaisait au peuple, et n'avait pas peu contribué à lui\r
+donner accès près de tous les esprits. Il était dans la chaumière et\r
+dans la montagne comme chez lui. Il savait dire les choses les plus\r
+grandes dans les idiomes les plus vulgaires. Parlant toutes les langues,\r
+il entrait dans toutes les âmes. Du reste, il était le même pour les\r
+gens du monde et pour les gens du peuple. Il ne condamnait rien\r
+hâtivement, et sans tenir compte des circonstances environnantes. Il\r
+disait:\r
+\r
+--Voyons le chemin par où la faute a passé.\r
+\r
+Étant, comme il se qualifiait lui-même en souriant, un _ex-pécheur_, il\r
+n'avait aucun des escarpements du rigorisme, et il professait assez\r
+haut, et sans le froncement de sourcil des vertueux féroces, une\r
+doctrine qu'on pourrait résumer à peu près ainsi:\r
+\r
+«L'homme a sur lui la chair qui est tout à la fois son fardeau et sa\r
+tentation. Il la traîne et lui cède.\r
+\r
+«Il doit la surveiller, la contenir, la réprimer, et ne lui obéir qu'à\r
+la dernière extrémité. Dans cette obéissance-là, il peut encore y avoir\r
+de la faute; mais la faute, ainsi faite, est vénielle. C'est une chute,\r
+mais une chute sur les genoux, qui peut s'achever en prière.\r
+\r
+«Être un saint, c'est l'exception; être un juste, c'est la règle. Errez,\r
+défaillez, péchez, mais soyez des justes.\r
+\r
+«Le moins de péché possible, c'est la loi de l'homme. Pas de péché du\r
+tout est le rêve de l'ange. Tout ce qui est terrestre est soumis au\r
+péché. Le péché est une gravitation.»\r
+\r
+Quand il voyait tout le monde crier bien fort et s'indigner bien vite:\r
+\r
+--Oh! oh! disait-il en souriant, il y a apparence que ceci est un gros\r
+crime que tout le monde commet. Voilà les hypocrisies effarées qui se\r
+dépêchent de protester et de se mettre à couvert.\r
+\r
+Il était indulgent pour les femmes et les pauvres sur qui pèse le poids\r
+de la société humaine. Il disait:\r
+\r
+--Les fautes des femmes, des enfants, des serviteurs, des faibles, des\r
+indigents et des ignorants sont la faute des maris, des pères, des\r
+maîtres, des forts, des riches et des savants.\r
+\r
+Il disait encore:\r
+\r
+--À ceux qui ignorent, enseignez-leur le plus de choses que vous\r
+pourrez; la société est coupable de ne pas donner l'instruction gratis;\r
+elle répond de la nuit qu'elle produit. Cette âme est pleine d'ombre, le\r
+péché s'y commet. Le coupable n'est pas celui qui y fait le péché, mais\r
+celui qui y a fait l'ombre.\r
+\r
+Comme on voit, il avait une manière étrange et à lui de juger les\r
+choses. Je soupçonne qu'il avait pris cela dans l'évangile.\r
+\r
+Il entendit un jour conter dans un salon un procès criminel qu'on\r
+instruisait et qu'on allait juger. Un misérable homme, par amour pour\r
+une femme et pour l'enfant qu'il avait d'elle, à bout de ressources,\r
+avait fait de la fausse monnaie. La fausse monnaie était encore punie de\r
+mort à cette époque. La femme avait été arrêtée émettant la première\r
+pièce fausse fabriquée par l'homme. On la tenait, mais on n'avait de\r
+preuves que contre elle. Elle seule pouvait charger son amant et le\r
+perdre en avouant. Elle nia. On insista. Elle s'obstina à nier. Sur ce,\r
+le procureur du roi avait eu une idée. Il avait supposé une infidélité\r
+de l'amant, et était parvenu, avec des fragments de lettres savamment\r
+présentés, à persuader à la malheureuse qu'elle avait une rivale et que\r
+cet homme la trompait. Alors, exaspérée de jalousie, elle avait dénoncé\r
+son amant, tout avoué, tout prouvé. L'homme était perdu. Il allait être\r
+prochainement jugé à Aix avec sa complice. On racontait le fait, et\r
+chacun s'extasiait sur l'habileté du magistrat. En mettant la jalousie\r
+en jeu, il avait fait jaillir la vérité par la colère, il avait fait\r
+sortir la justice de la vengeance. L'évêque écoutait tout cela en\r
+silence. Quand ce fut fini, il demanda:\r
+\r
+--Où jugera-t-on cet homme et cette femme?\r
+\r
+--À la cour d'assises.\r
+\r
+Il reprit:\r
+\r
+--Et où jugera-t-on monsieur le procureur du roi?\r
+\r
+Il arriva à Digne une aventure tragique. Un homme fut condamné à mort\r
+pour meurtre. C'était un malheureux pas tout à fait lettré, pas tout à\r
+fait ignorant, qui avait été bateleur dans les foires et écrivain\r
+public. Le procès occupa beaucoup la ville. La veille du jour fixé pour\r
+l'exécution du condamné, l'aumônier de la prison tomba malade. Il\r
+fallait un prêtre pour assister le patient à ses derniers moments. On\r
+alla chercher le curé. Il paraît qu'il refusa en disant: Cela ne me\r
+regarde pas. Je n'ai que faire de cette corvée et de ce saltimbanque;\r
+moi aussi, je suis malade; d'ailleurs ce n'est pas là ma place. On\r
+rapporta cette réponse à l'évêque qui dit:\r
+\r
+--Monsieur le curé a raison. Ce n'est pas sa place, c'est la mienne.\r
+\r
+Il alla sur-le-champ à la prison, il descendit au cabanon du\r
+«saltimbanque», il l'appela par son nom, lui prit la main et lui parla.\r
+Il passa toute la journée et toute la nuit près de lui, oubliant la\r
+nourriture et le sommeil, priant Dieu pour l'âme du condamné et priant\r
+le condamné pour la sienne propre. Il lui dit les meilleures vérités qui\r
+sont les plus simples. Il fut père, frère, ami; évêque pour bénir\r
+seulement. Il lui enseigna tout, en le rassurant et en le consolant. Cet\r
+homme allait mourir désespéré. La mort était pour lui comme un abîme.\r
+Debout et frémissant sur ce seuil lugubre, il reculait avec horreur. Il\r
+n'était pas assez ignorant pour être absolument indifférent. Sa\r
+condamnation, secousse profonde, avait en quelque sorte rompu çà et là\r
+autour de lui cette cloison qui nous sépare du mystère des choses et que\r
+nous appelons la vie. Il regardait sans cesse au dehors de ce monde par\r
+ces brèches fatales, et ne voyait que des ténèbres. L'évêque lui fit\r
+voir une clarté.\r
+\r
+Le lendemain, quand on vint chercher le malheureux, l'évêque était là.\r
+Il le suivit. Il se montra aux yeux de la foule en camail violet et avec\r
+sa croix épiscopale au cou, côte à côte avec ce misérable lié de cordes.\r
+\r
+Il monta sur la charrette avec lui, il monta sur l'échafaud avec lui. Le\r
+patient, si morne et si accablé la veille, était rayonnant. Il sentait\r
+que son âme était réconciliée et il espérait Dieu. L'évêque l'embrassa,\r
+et, au moment où le couteau allait tomber, il lui dit:\r
+\r
+--Celui que l'homme tue, Dieu le ressuscite; celui que les frères\r
+chassent retrouve le Père. Priez, croyez, entrez dans la vie! le Père\r
+est là.\r
+\r
+Quand il redescendit de l'échafaud, il avait quelque chose dans son\r
+regard qui fit ranger le peuple. On ne savait ce qui était le plus\r
+admirable de sa pâleur ou de sa sérénité. En rentrant à cet humble logis\r
+qu'il appelait en souriant son palais, il dit à sa soeur:\r
+\r
+--Je viens d'officier pontificalement.\r
+\r
+Comme les choses les plus sublimes sont souvent aussi les choses les\r
+moins comprises, il y eut dans la ville des gens qui dirent, en\r
+commentant cette conduite de l'évêque: «C'est de l'affectation.» Ceci ne\r
+fut du reste qu'un propos de salons. Le peuple, qui n'entend pas malice\r
+aux actions saintes, fut attendri et admira.\r
+\r
+Quant à l'évêque, avoir vu la guillotine fut pour lui un choc, et il fut\r
+longtemps à s'en remettre.\r
+\r
+L'échafaud, en effet, quand il est là, dressé et debout, a quelque chose\r
+qui hallucine. On peut avoir une certaine indifférence sur la peine de\r
+mort, ne point se prononcer, dire oui et non, tant qu'on n'a pas vu de\r
+ses yeux une guillotine; mais si l'on en rencontre une, la secousse est\r
+violente, il faut se décider et prendre parti pour ou contre. Les uns\r
+admirent, comme de Maistre; les autres exècrent, comme Beccaria. La\r
+guillotine est la concrétion de la loi; elle se nomme _vindicte;_ elle\r
+n'est pas neutre, et ne vous permet pas de rester neutre. Qui l'aperçoit\r
+frissonne du plus mystérieux des frissons. Toutes les questions sociales\r
+dressent autour de ce couperet leur point d'interrogation. L'échafaud\r
+est vision. L'échafaud n'est pas une charpente, l'échafaud n'est pas une\r
+machine, l'échafaud n'est pas une mécanique inerte faite de bois, de fer\r
+et de cordes. Il semble que ce soit une sorte d'être qui a je ne sais\r
+quelle sombre initiative; on dirait que cette charpente voit, que cette\r
+machine entend, que cette mécanique comprend, que ce bois, ce fer et ces\r
+cordes veulent. Dans la rêverie affreuse où sa présence jette l'âme,\r
+l'échafaud apparaît terrible et se mêlant de ce qu'il fait. L'échafaud\r
+est le complice du bourreau; il dévore; il mange de la chair, il boit du\r
+sang. L'échafaud est une sorte de monstre fabriqué par le juge et par le\r
+charpentier, un spectre qui semble vivre d'une espèce de vie\r
+épouvantable faite de toute la mort qu'il a donnée.\r
+\r
+Aussi l'impression fut-elle horrible et profonde; le lendemain de\r
+l'exécution et beaucoup de jours encore après, l'évêque parut accablé.\r
+La sérénité presque violente du moment funèbre avait disparu: le fantôme\r
+de la justice sociale l'obsédait. Lui qui d'ordinaire revenait de toutes\r
+ses actions avec une satisfaction si rayonnante, il semblait qu'il se\r
+fît un reproche. Par moments, il se parlait à lui-même, et bégayait à\r
+demi-voix des monologues lugubres. En voici un que sa soeur entendit un\r
+soir et recueillit:\r
+\r
+--Je ne croyais pas que cela fût si monstrueux. C'est un tort de\r
+s'absorber dans la loi divine au point de ne plus s'apercevoir de la loi\r
+humaine. La mort n'appartient qu'à Dieu. De quel droit les hommes\r
+touchent-ils à cette chose inconnue?\r
+\r
+Avec le temps ces impressions s'atténuèrent, et probablement\r
+s'effacèrent. Cependant on remarqua que l'évêque évitait désormais de\r
+passer sur la place des exécutions. On pouvait appeler M. Myriel à toute\r
+heure au chevet des malades et des mourants. Il n'ignorait pas que là\r
+était son plus grand devoir et son plus grand travail. Les familles\r
+veuves ou orphelines n'avaient pas besoin de le demander, il arrivait de\r
+lui-même. Il savait s'asseoir et se taire de longues heures auprès de\r
+l'homme qui avait perdu la femme qu'il aimait, de la mère qui avait\r
+perdu son enfant. Comme il savait le moment de se taire, il savait aussi\r
+le moment de parler. Ô admirable consolateur! il ne cherchait pas à\r
+effacer la douleur par l'oubli, mais à l'agrandir et à la dignifier par\r
+l'espérance. Il disait:\r
+\r
+--Prenez garde à la façon dont vous vous tournez vers les morts. Ne\r
+songez pas à ce qui pourrit. Regardez fixement. Vous apercevrez la lueur\r
+vivante de votre mort bien-aimé au fond du ciel.\r
+\r
+Il savait que la croyance est saine. Il cherchait à conseiller et à\r
+calmer l'homme désespéré en lui indiquant du doigt l'homme résigné, et à\r
+transformer la douleur qui regarde une fosse en lui montrant la douleur\r
+qui regarde une étoile.\r
+\r
+\r
+\r
+\r
+Chapitre V\r
+\r
+Que monseigneur Bienvenu faisait durer trop longtemps ses soutanes\r
+\r
+\r
+La vie intérieure de M. Myriel était pleine des mêmes pensées que sa vie\r
+publique. Pour qui eût pu la voir de près, c'eût été un spectacle grave\r
+et charmant que cette pauvreté volontaire dans laquelle vivait M.\r
+l'évêque de Digne.\r
+\r
+Comme tous les vieillards et comme la plupart des penseurs, il dormait\r
+peu. Ce court sommeil était profond. Le matin il se recueillait pendant\r
+une heure, puis il disait sa messe, soit à la cathédrale, soit dans son\r
+oratoire. Sa messe dite, il déjeunait d'un pain de seigle trempé dans le\r
+lait de ses vaches. Puis il travaillait.\r
+\r
+Un évêque est un homme fort occupé; il faut qu'il reçoive tous les jours\r
+le secrétaire de l'évêché, qui est d'ordinaire un chanoine, presque tous\r
+les jours ses grands vicaires. Il a des congrégations à contrôler, des\r
+privilèges à donner, toute une librairie ecclésiastique à examiner,\r
+paroissiens, catéchismes diocésains, livres d'heures, etc., des\r
+mandements à écrire, des prédications à autoriser, des curés et des\r
+maires à mettre d'accord, une correspondance cléricale, une\r
+correspondance administrative, d'un côté l'état, de l'autre le\r
+Saint-Siège, mille affaires.\r
+\r
+Le temps que lui laissaient ces mille affaires, ses offices et son\r
+bréviaire, il le donnait d'abord aux nécessiteux, aux malades et aux\r
+affligés; le temps que les affligés, les malades et les nécessiteux lui\r
+laissaient, il le donnait au travail. Tantôt il bêchait la terre dans\r
+son jardin, tantôt il lisait et écrivait. Il n'avait qu'un mot pour ces\r
+deux sortes de travail; il appelait cela _jardiner_.\r
+\r
+--L'esprit est un jardin, disait-il.\r
+\r
+À midi, il dînait. Le dîner ressemblait au déjeuner.\r
+\r
+Vers deux heures, quand le temps était beau, il sortait et se promenait\r
+à pied dans la campagne ou dans la ville, entrant souvent dans les\r
+masures. On le voyait cheminer seul, tout à ses pensées, l'oeil baissé,\r
+appuyé sur sa longue canne, vêtu de sa douillette violette ouatée et\r
+bien chaude, chaussé de bas violets dans de gros souliers, et coiffé de\r
+son chapeau plat qui laissait passer par ses trois cornes trois glands\r
+d'or à graine d'épinards.\r
+\r
+C'était une fête partout où il paraissait. On eût dit que son passage\r
+avait quelque chose de réchauffant et de lumineux. Les enfants et les\r
+vieillards venaient sur le seuil des portes pour l'évêque comme pour le\r
+soleil. Il bénissait et on le bénissait. On montrait sa maison à\r
+quiconque avait besoin de quelque chose.\r
+\r
+Çà et là, il s'arrêtait, parlait aux petits garçons et aux petites\r
+filles et souriait aux mères. Il visitait les pauvres tant qu'il avait\r
+de l'argent; quand il n'en avait plus, il visitait les riches.\r
+\r
+Comme il faisait durer ses soutanes beaucoup de temps, et qu'il ne\r
+voulait pas qu'on s'en aperçût, il ne sortait jamais dans la ville\r
+autrement qu'avec sa douillette violette. Cela le gênait un peu en été.\r
+\r
+Le soir à huit heures et demie il soupait avec sa soeur, madame Magloire\r
+debout derrière eux et les servant à table. Rien de plus frugal que ce\r
+repas. Si pourtant l'évêque avait un de ses curés à souper, madame\r
+Magloire en profitait pour servir à Monseigneur quelque excellent\r
+poisson des lacs ou quelque fin gibier de la montagne. Tout curé était\r
+un prétexte à bon repas; l'évêque se laissait faire. Hors de là, son\r
+ordinaire ne se composait guère que de légumes cuits dans l'eau et de\r
+soupe à l'huile. Aussi disait-on dans la ville:\r
+\r
+--Quand l'évêque fait pas chère de curé, il fait chère de trappiste.\r
+\r
+Après son souper, il causait pendant une demi-heure avec mademoiselle\r
+Baptistine et madame Magloire; puis il rentrait dans sa chambre et se\r
+remettait à écrire, tantôt sur des feuilles volantes, tantôt sur la\r
+marge de quelque in-folio. Il était lettré et quelque peu savant. Il a\r
+laissé cinq ou six manuscrits assez curieux; entre autres une\r
+dissertation sur le verset de la Genèse: _Au commencement l'esprit de\r
+Dieu flottait sur les eaux_. Il confronte avec ce verset trois textes:\r
+la version arabe qui dit: _Les vents de Dieu soufflaient;_ Flavius\r
+Josèphe qui dit: _Un vent d'en haut se précipitait sur la terre_, et\r
+enfin la paraphrase chaldaïque d'Onkelos qui porte: _Un vent venant de\r
+Dieu soufflait sur la face des eaux_. Dans une autre dissertation, il\r
+examine les oeuvres théologiques de Hugo, évêque de Ptolémaïs,\r
+arrière-grand-oncle de celui qui écrit ce livre, et il établit qu'il\r
+faut attribuer à cet évêque les divers opuscules publiés, au siècle\r
+dernier, sous le pseudonyme de Barleycourt.\r
+\r
+Parfois au milieu d'une lecture, quel que fût le livre qu'il eût entre\r
+les mains, il tombait tout à coup dans une méditation profonde, d'où il\r
+ne sortait que pour écrire quelques lignes sur les pages mêmes du\r
+volume. Ces lignes souvent n'ont aucun rapport avec le livre qui les\r
+contient. Nous avons sous les yeux une note écrite par lui sur une des\r
+marges d'un in-quarto intitulé: _Correspondance du lord Germain avec les\r
+généraux Clinton, Cornwallis et les amiraux de la station de l'Amérique.\r
+À Versailles, chez Poinçot, libraire, et à Paris, chez Pissot, libraire,\r
+quai des Augustins_.\r
+\r
+Voici cette note:\r
+\r
+«Ô vous qui êtes!\r
+\r
+«L'Ecclésiaste vous nomme Toute-Puissance, les Macchabées vous nomment\r
+Créateur, l'Épître aux Éphésiens vous nomme Liberté, Baruch vous nomme\r
+Immensité, les Psaumes vous nomment Sagesse et Vérité, Jean vous nomme\r
+Lumière, les Rois vous nomment Seigneur, l'Exode vous appelle\r
+Providence, le Lévitique Sainteté, Esdras Justice, la création vous\r
+nomme Dieu, l'homme vous nomme Père; mais Salomon vous nomme\r
+Miséricorde, et c'est là le plus beau de tous vos noms.»\r
+\r
+Vers neuf heures du soir, les deux femmes se retiraient et montaient à\r
+leurs chambres au premier, le laissant jusqu'au matin seul au\r
+rez-de-chaussée.\r
+\r
+Ici il est nécessaire que nous donnions une idée exacte du logis de M.\r
+l'évêque de Digne.\r
+\r
+\r
+\r
+\r
+Chapitre VI\r
+\r
+Par qui il faisait garder sa maison\r
+\r
+\r
+La maison qu'il habitait se composait, nous l'avons dit, d'un\r
+rez-de-chaussée et d'un seul étage: trois pièces au rez-de-chaussée,\r
+trois chambres au premier, au-dessus un grenier. Derrière la maison, un\r
+jardin d'un quart d'arpent. Les deux femmes occupaient le premier.\r
+L'évêque logeait en bas. La première pièce, qui s'ouvrait sur la rue,\r
+lui servait de salle à manger, la deuxième de chambre à coucher, et la\r
+troisième d'oratoire. On ne pouvait sortir de cet oratoire sans passer\r
+par la chambre à coucher, et sortir de la chambre à coucher sans passer\r
+par la salle à manger. Dans l'oratoire, au fond, il y avait une alcôve\r
+fermée, avec un lit pour les cas d'hospitalité. M. l'évêque offrait ce\r
+lit aux curés de campagne que des affaires ou les besoins de leur\r
+paroisse amenaient à Digne.\r
+\r
+La pharmacie de l'hôpital, petit bâtiment ajouté à la maison et pris sur\r
+le jardin, avait été transformée en cuisine et en cellier.\r
+\r
+Il y avait en outre dans le jardin une étable qui était l'ancienne\r
+cuisine de l'hospice et où l'évêque entretenait deux vaches. Quelle que\r
+fût la quantité de lait qu'elles lui donnassent, il en envoyait\r
+invariablement tous les matins la moitié aux malades de l'hôpital.--Je\r
+paye ma dîme, disait-il.\r
+\r
+Sa chambre était assez grande et assez difficile à chauffer dans la\r
+mauvaise saison. Comme le bois est très cher à Digne, il avait imaginé\r
+de faire faire dans l'étable à vaches un compartiment fermé d'une\r
+cloison en planches. C'était là qu'il passait ses soirées dans les\r
+grands froids. Il appelait cela son _salon d'hiver_.\r
+\r
+Il n'y avait dans ce salon d'hiver, comme dans la salle à manger,\r
+d'autres meubles qu'une table de bois blanc, carrée, et quatre chaises\r
+de paille. La salle à manger était ornée en outre d'un vieux buffet\r
+peint en rose à la détrempe. Du buffet pareil, convenablement habillé de\r
+napperons blancs et de fausses dentelles, l'évêque avait fait l'autel\r
+qui décorait son oratoire.\r
+\r
+Ses pénitentes riches et les saintes femmes de Digne s'étaient souvent\r
+cotisées pour faire les frais d'un bel autel neuf à l'oratoire de\r
+monseigneur; il avait chaque fois pris l'argent et l'avait donné aux\r
+pauvres.\r
+\r
+--Le plus beau des autels, disait-il, c'est l'âme d'un malheureux\r
+consolé qui remercie Dieu.\r
+\r
+Il avait dans son oratoire deux chaises prie-Dieu en paille, et un\r
+fauteuil à bras également en paille dans sa chambre à coucher. Quand par\r
+hasard il recevait sept ou huit personnes à la fois, le préfet, ou le\r
+général, ou l'état-major du régiment en garnison, ou quelques élèves du\r
+petit séminaire, on était obligé d'aller chercher dans l'étable les\r
+chaises du salon d'hiver, dans l'oratoire les prie-Dieu, et le fauteuil\r
+dans la chambre à coucher; de cette façon, on pouvait réunir jusqu'à\r
+onze sièges pour les visiteurs. À chaque nouvelle visite on démeublait\r
+une pièce.\r
+\r
+Il arrivait parfois qu'on était douze; alors l'évêque dissimulait\r
+l'embarras de la situation en se tenant debout devant la cheminée si\r
+c'était l'hiver, ou en proposant un tour dans le jardin si c'était\r
+l'été.\r
+\r
+Il y avait bien encore dans l'alcôve fermée une chaise, mais elle était\r
+à demi dépaillée et ne portait que sur trois pieds, ce qui faisait\r
+qu'elle ne pouvait servir qu'appuyée contre le mur. Mademoiselle\r
+Baptistine avait bien aussi dans sa chambre une très grande bergère en\r
+bois jadis doré et revêtue de pékin à fleurs, mais on avait été obligé\r
+de monter cette bergère au premier par la fenêtre, l'escalier étant trop\r
+étroit; elle ne pouvait donc pas compter parmi les en-cas du mobilier.\r
+\r
+L'ambition de mademoiselle Baptistine eût été de pouvoir acheter un\r
+meuble de salon en velours d'Utrecht jaune à rosaces et en acajou à cou\r
+de cygne, avec canapé. Mais cela eût coûté au moins cinq cents francs,\r
+et, ayant vu qu'elle n'avait réussi à économiser pour cet objet que\r
+quarante-deux francs dix sous en cinq ans, elle avait fini par y\r
+renoncer. D'ailleurs qui est-ce qui atteint son idéal?\r
+\r
+Rien de plus simple à se figurer que la chambre à coucher de l'évêque.\r
+Une porte-fenêtre donnant sur le jardin, vis-à-vis le lit; un lit\r
+d'hôpital, en fer avec baldaquin de serge verte; dans l'ombre du lit,\r
+derrière un rideau, les ustensiles de toilette trahissant encore les\r
+anciennes habitudes élégantes de l'homme du monde; deux portes, l'une\r
+près de la cheminée, donnant dans l'oratoire; l'autre, près de la\r
+bibliothèque, donnant dans la salle à manger; la bibliothèque, grande\r
+armoire vitrée pleine de livres; la cheminée, de bois peint en marbre,\r
+habituellement sans feu; dans la cheminée, une paire de chenets en fer\r
+ornés de deux vases à guirlandes et cannelures jadis argentés à l'argent\r
+haché, ce qui était un genre de luxe épiscopal; au-dessus, à l'endroit\r
+où d'ordinaire on met la glace, un crucifix de cuivre désargenté fixé\r
+sur un velours noir râpé dans un cadre de bois dédoré. Près de la\r
+porte-fenêtre, une grande table avec un encrier, chargée de papiers\r
+confus et de gros volumes. Devant la table, le fauteuil de paille.\r
+Devant le lit, un prie-Dieu, emprunté à l'oratoire.\r
+\r
+Deux portraits dans des cadres ovales étaient accrochés au mur des deux\r
+côtés du lit. De petites inscriptions dorées sur le fond neutre de la\r
+toile à côté des figures indiquaient que les portraits représentaient,\r
+l'un, l'abbé de Chaliot, évêque de Saint-Claude, l'autre, l'abbé\r
+Tourteau, vicaire général d'Agde, abbé de Grand-Champ, ordre de Cîteaux,\r
+diocèse de Chartres. L'évêque, en succédant dans cette chambre aux\r
+malades de l'hôpital, y avait trouvé ces portraits et les y avait\r
+laissés. C'étaient des prêtres, probablement des donateurs: deux motifs\r
+pour qu'il les respectât. Tout ce qu'il savait de ces deux personnages,\r
+c'est qu'ils avaient été nommés par le roi, l'un à son évêché, l'autre à\r
+son bénéfice, le même jour, le 27 avril 1785. Madame Magloire ayant\r
+décroché les tableaux pour en secouer la poussière, l'évêque avait\r
+trouvé cette particularité écrite d'une encre blanchâtre sur un petit\r
+carré de papier jauni par le temps, collé avec quatre pains à cacheter\r
+derrière le portrait de l'abbé de Grand-Champ.\r
+\r
+Il avait à sa fenêtre un antique rideau de grosse étoffe de laine qui\r
+finit par devenir tellement vieux que, pour éviter la dépense d'un neuf,\r
+madame Magloire fut obligée de faire une grande couture au beau milieu.\r
+Cette couture dessinait une croix. L'évêque le faisait souvent\r
+remarquer.\r
+\r
+--Comme cela fait bien! disait-il.\r
+\r
+Toutes les chambres de la maison, au rez-de-chaussée ainsi qu'au\r
+premier, sans exception, étaient blanchies au lait de chaux, ce qui est\r
+une mode de caserne et d'hôpital.\r
+\r
+Cependant, dans les dernières années, madame Magloire retrouva, comme on\r
+le verra plus loin, sous le papier badigeonné, des peintures qui\r
+ornaient l'appartement de mademoiselle Baptistine. Avant d'être\r
+l'hôpital, cette maison avait été le parloir aux bourgeois. De là cette\r
+décoration. Les chambres étaient pavées de briques rouges qu'on lavait\r
+toutes les semaines, avec des nattes de paille tressée devant tous les\r
+lits. Du reste, ce logis, tenu par deux femmes, était du haut en bas\r
+d'une propreté exquise. C'était le seul luxe que l'évêque permit. Il\r
+disait:\r
+\r
+--Cela ne prend rien aux pauvres.\r
+\r
+Il faut convenir cependant qu'il lui restait de ce qu'il avait possédé\r
+jadis six couverts d'argent et une grande cuiller à soupe que madame\r
+Magloire regardait tous les jours avec bonheur reluire splendidement sur\r
+la grosse nappe de toile blanche. Et comme nous peignons ici l'évêque de\r
+Digne tel qu'il était, nous devons ajouter qu'il lui était arrivé plus\r
+d'une fois de dire:\r
+\r
+--Je renoncerais difficilement à manger dans de l'argenterie.\r
+\r
+Il faut ajouter à cette argenterie deux gros flambeaux d'argent massif\r
+qui lui venaient de l'héritage d'une grand'tante. Ces flambeaux\r
+portaient deux bougies de cire et figuraient habituellement sur la\r
+cheminée de l'évêque. Quand il avait quelqu'un à dîner, madame Magloire\r
+allumait les deux bougies et mettait les deux flambeaux sur la table.\r
+\r
+Il y avait dans la chambre même de l'évêque, à la tête de son lit, un\r
+petit placard dans lequel madame Magloire serrait chaque soir les six\r
+couverts d'argent et la grande cuiller. Il faut dire qu'on n'en ôtait\r
+jamais la clef.\r
+\r
+Le jardin, un peu gâté par les constructions assez laides dont nous\r
+avons parlé, se composait de quatre allées en croix rayonnant autour\r
+d'un puisard; une autre allée faisait tout le tour du jardin et\r
+cheminait le long du mur blanc dont il était enclos. Ces allées\r
+laissaient entre elles quatre carrés bordés de buis. Dans trois, madame\r
+Magloire cultivait des légumes; dans le quatrième, l'évêque avait mis\r
+des fleurs. Il y avait çà et là quelques arbres fruitiers.\r
+\r
+Une fois madame Magloire lui avait dit avec une sorte de malice douce:\r
+\r
+--Monseigneur, vous qui tirez parti de tout, voilà pourtant un carré\r
+inutile. Il vaudrait mieux avoir là des salades que des bouquets.\r
+\r
+--Madame Magloire, répondit l'évêque, vous vous trompez. Le beau est\r
+aussi utile que l'utile.\r
+\r
+Il ajouta après un silence:\r
+\r
+--Plus peut-être.\r
+\r
+Ce carré, composé de trois ou quatre plates-bandes, occupait M. l'évêque\r
+presque autant que ses livres. Il y passait volontiers une heure ou\r
+deux, coupant, sarclant, et piquant çà et là des trous en terre où il\r
+mettait des graines. Il n'était pas aussi hostile aux insectes qu'un\r
+jardinier l'eût voulu. Du reste, aucune prétention à la botanique; il\r
+ignorait les groupes et le solidisme; il ne cherchait pas le moins du\r
+monde à décider entre Tournefort et la méthode naturelle; il ne prenait\r
+parti ni pour les utricules contre les cotylédons, ni pour Jussieu\r
+contre Linné. Il n'étudiait pas les plantes; il aimait les fleurs. Il\r
+respectait beaucoup les savants, il respectait encore plus les\r
+ignorants, et, sans jamais manquer à ces deux respects, il arrosait ses\r
+plates-bandes chaque soir d'été avec un arrosoir de fer-blanc peint en\r
+vert.\r
+\r
+La maison n'avait pas une porte qui fermât à clef. La porte de la salle\r
+à manger qui, nous l'avons dit, donnait de plain-pied sur la place de la\r
+cathédrale, était jadis armée de serrures et de verrous comme une porte\r
+de prison. L'évêque avait fait ôter toutes ces ferrures, et cette porte,\r
+la nuit comme le jour, n'était fermée qu'au loquet. Le premier passant\r
+venu, à quelque heure que ce fût, n'avait qu'à la pousser. Dans les\r
+commencements, les deux femmes avaient été fort tourmentées de cette\r
+porte jamais close; mais M. de Digne leur avait dit:\r
+\r
+--Faites mettre des verrous à vos chambres, si cela vous plaît.\r
+\r
+Elles avaient fini par partager sa confiance ou du moins par faire comme\r
+si elles la partageaient. Madame Magloire seule avait de temps en temps\r
+des frayeurs. Pour ce qui est de l'évêque, on peut trouver sa pensée\r
+expliquée ou du moins indiquée dans ces trois lignes écrites par lui sur\r
+la marge d'une bible: «Voici la nuance: la porte du médecin ne doit\r
+jamais être fermée; la porte du prêtre doit toujours être ouverte.» Sur\r
+un autre livre, intitulé _Philosophie de la science médicale_, il avait\r
+écrit cette autre note: «Est-ce que je ne suis pas médecin comme eux?\r
+Moi aussi j'ai mes malades; d'abord j'ai les leurs, qu'ils appellent les\r
+malades; et puis j'ai les miens, que j'appelle les malheureux.»\r
+\r
+Ailleurs encore il avait écrit: «Ne demandez pas son nom à qui vous\r
+demande un gîte. C'est surtout celui-là que son nom embarrasse qui a\r
+besoin d'asile.»\r
+\r
+Il advint qu'un digne curé, je ne sais plus si c'était le curé de\r
+Couloubroux ou le curé de Pompierry, s'avisa de lui demander un jour,\r
+probablement à l'instigation de madame Magloire, si Monseigneur était\r
+bien sûr de ne pas commettre jusqu'à un certain point une imprudence en\r
+laissant jour et nuit sa porte ouverte à la disposition de qui voulait\r
+entrer, et s'il ne craignait pas enfin qu'il n'arrivât quelque malheur\r
+dans une maison si peu gardée. L'évêque lui toucha l'épaule avec une\r
+gravité douce et lui dit:--_Nisi Dominus custodierit domum, in vanum\r
+vigilant qui custodiunt eam_.\r
+\r
+Puis il parla d'autre chose.\r
+\r
+Il disait assez volontiers:\r
+\r
+--Il y a la bravoure du prêtre comme il y a la bravoure du colonel de\r
+dragons. Seulement, ajoutait-il, la nôtre doit être tranquille.\r
+\r
+\r
+\r
+\r
+Chapitre VII\r
+\r
+Cravatte\r
+\r
+\r
+Ici se place naturellement un fait que nous ne devons pas omettre, car\r
+il est de ceux qui font le mieux voir quel homme c'était que M. l'évêque\r
+de Digne.\r
+\r
+Après la destruction de la bande de Gaspard Bès qui avait infesté les\r
+gorges d'Ollioules, un de ses lieutenants, Cravatte, se réfugia dans la\r
+montagne. Il se cacha quelque temps avec ses bandits, reste de la troupe\r
+de Gaspard Bès, dans le comté de Nice, puis gagna le Piémont, et tout à\r
+coup reparut en France, du côté de Barcelonnette. On le vit à Jauziers\r
+d'abord, puis aux Tuiles. Il se cacha dans les cavernes du\r
+Joug-de-l'Aigle, et de là il descendait vers les hameaux et les villages\r
+par les ravins de l'Ubaye et de l'Ubayette. Il osa même pousser jusqu'à\r
+Embrun, pénétra une nuit dans la cathédrale et dévalisa la sacristie.\r
+Ses brigandages désolaient le pays. On mit la gendarmerie à ses\r
+trousses, mais en vain. Il échappait toujours; quelquefois il résistait\r
+de vive force. C'était un hardi misérable. Au milieu de toute cette\r
+terreur, l'évêque arriva. Il faisait sa tournée. Au Chastelar, le maire\r
+vint le trouver et l'engagea à rebrousser chemin. Cravatte tenait la\r
+montagne jusqu'à l'Arche, et au-delà. Il y avait danger, même avec une\r
+escorte. C'était exposer inutilement trois ou quatre malheureux\r
+gendarmes.\r
+\r
+--Aussi, dit l'évêque, je compte aller sans escorte.\r
+\r
+--Y pensez-vous, monseigneur? s'écria le maire.\r
+\r
+--J'y pense tellement, que je refuse absolument les gendarmes et que je\r
+vais partir dans une heure.\r
+\r
+--Partir?\r
+\r
+--Partir.\r
+\r
+--Seul?\r
+\r
+--Seul.\r
+\r
+--Monseigneur! vous ne ferez pas cela.\r
+\r
+--Il y a là, dans la montagne, reprit l'évêque, une humble petite\r
+commune grande comme ça, que je n'ai pas vue depuis trois ans. Ce sont\r
+mes bons amis. De doux et honnêtes bergers. Ils possèdent une chèvre sur\r
+trente qu'ils gardent. Ils font de fort jolis cordons de laine de\r
+diverses couleurs, et ils jouent des airs de montagne sur de petites\r
+flûtes à six trous. Ils ont besoin qu'on leur parle de temps en temps du\r
+bon Dieu. Que diraient-ils d'un évêque qui a peur? Que diraient-ils si\r
+je n'y allais pas?\r
+\r
+--Mais, monseigneur, les brigands! Si vous rencontrez les brigands!\r
+\r
+--Tiens, dit l'évêque, j'y songe. Vous avez raison. Je puis les\r
+rencontrer. Eux aussi doivent avoir besoin qu'on leur parle du bon Dieu.\r
+\r
+--Monseigneur! mais c'est une bande! c'est un troupeau de loups!\r
+\r
+--Monsieur le maire, c'est peut-être précisément de ce troupeau que\r
+Jésus me fait le pasteur. Qui sait les voies de la Providence?\r
+\r
+--Monseigneur, ils vous dévaliseront.\r
+\r
+--Je n'ai rien.\r
+\r
+--Ils vous tueront.\r
+\r
+--Un vieux bonhomme de prêtre qui passe en marmottant ses momeries? Bah!\r
+à quoi bon?\r
+\r
+--Ah! mon Dieu! si vous alliez les rencontrer!\r
+\r
+--Je leur demanderai l'aumône pour mes pauvres.\r
+\r
+--Monseigneur, n'y allez pas, au nom du ciel! vous exposez votre vie.\r
+\r
+--Monsieur le maire, dit l'évêque, n'est-ce décidément que cela? Je ne\r
+suis pas en ce monde pour garder ma vie, mais pour garder les âmes.\r
+\r
+Il fallut le laisser faire. Il partit, accompagné seulement d'un enfant\r
+qui s'offrit à lui servir de guide. Son obstination fit bruit dans le\r
+pays, et effraya très fort.\r
+\r
+Il ne voulut emmener ni sa soeur ni madame Magloire. Il traversa la\r
+montagne à mulet, ne rencontra personne, et arriva sain et sauf chez ses\r
+«bons amis» les bergers. Il y resta quinze jours, prêchant,\r
+administrant, enseignant, moralisant. Lorsqu'il fut proche de son\r
+départ, il résolut de chanter pontificalement un _Te Deum_. Il en parla\r
+au curé. Mais comment faire? pas d'ornements épiscopaux. On ne pouvait\r
+mettre à sa disposition qu'une chétive sacristie de village avec\r
+quelques vieilles chasubles de damas usé ornées de galons faux.\r
+\r
+--Bah! dit l'évêque. Monsieur le curé, annonçons toujours au prône notre\r
+_Te Deum_. Cela s'arrangera.\r
+\r
+On chercha dans les églises d'alentour. Toutes les magnificences de ces\r
+humbles paroisses réunies n'auraient pas suffi à vêtir convenablement un\r
+chantre de cathédrale. Comme on était dans cet embarras, une grande\r
+caisse fut apportée et déposée au presbytère pour M. l'évêque par deux\r
+cavaliers inconnus qui repartirent sur-le-champ. On ouvrit la caisse;\r
+elle contenait une chape de drap d'or, une mitre ornée de diamants, une\r
+croix archiépiscopale, une crosse magnifique, tous les vêtements\r
+pontificaux volés un mois auparavant au trésor de Notre-Dame d'Embrun.\r
+Dans la caisse, il y avait un papier sur lequel étaient écrits ces mots:\r
+_Cravatte à monseigneur Bienvenu_.\r
+\r
+--Quand je disais que cela s'arrangerait! dit l'évêque.\r
+\r
+Puis il ajouta en souriant:\r
+\r
+--À qui se contente d'un surplis de curé, Dieu envoie une chape\r
+d'archevêque.\r
+\r
+--Monseigneur, murmura le curé en hochant la tête avec un sourire, Dieu,\r
+ou le diable.\r
+\r
+L'évêque regarda fixement le curé et reprit avec autorité:\r
+\r
+--Dieu!\r
+\r
+Quand il revint au Chastelar, et tout le long de la route, on venait le\r
+regarder par curiosité. Il retrouva au presbytère du Chastelar\r
+mademoiselle Baptistine et madame Magloire qui l'attendaient, et il dit\r
+à sa soeur:\r
+\r
+--Eh bien, avais-je raison? Le pauvre prêtre est allé chez ces pauvres\r
+montagnards les mains vides, il en revient les mains pleines. J'étais\r
+parti n'emportant que ma confiance en Dieu; je rapporte le trésor d'une\r
+cathédrale.\r
+\r
+Le soir, avant de se coucher, il dit encore:\r
+\r
+--Ne craignons jamais les voleurs ni les meurtriers. Ce sont là les\r
+dangers du dehors, les petits dangers. Craignons-nous nous-mêmes. Les\r
+préjugés, voilà les voleurs; les vices, voilà les meurtriers. Les grands\r
+dangers sont au dedans de nous. Qu'importe ce qui menace notre tête ou\r
+notre bourse! Ne songeons qu'à ce qui menace notre âme.\r
+\r
+Puis se tournant vers sa soeur:\r
+\r
+--Ma soeur, de la part du prêtre jamais de précaution contre le\r
+prochain. Ce que le prochain fait, Dieu le permet. Bornons-nous à prier\r
+Dieu quand nous croyons qu'un danger arrive sur nous. Prions-le, non\r
+pour nous, mais pour que notre frère ne tombe pas en faute à notre\r
+occasion.\r
+\r
+Du reste, les événements étaient rares dans son existence. Nous\r
+racontons ceux que nous savons; mais d'ordinaire il passait sa vie à\r
+faire toujours les mêmes choses aux mêmes moments. Un mois de son année\r
+ressemblait à une heure de sa journée.\r
+\r
+Quant à ce que devint «le trésor» de la cathédrale d'Embrun, on nous\r
+embarrasserait de nous interroger là-dessus. C'étaient là de bien belles\r
+choses, et bien tentantes, et bien bonnes à voler au profit des\r
+malheureux. Volées, elles l'étaient déjà d'ailleurs. La moitié de\r
+l'aventure était accomplie; il ne restait plus qu'à changer la direction\r
+du vol, et qu'à lui faire faire un petit bout de chemin du côté des\r
+pauvres. Nous n'affirmons rien du reste à ce sujet. Seulement on a\r
+trouvé dans les papiers de l'évêque une note assez obscure qui se\r
+rapporte peut-être à cette affaire, et qui est ainsi conçue: _La\r
+question est de savoir si cela doit faire retour à la cathédrale ou à\r
+l'hôpital_.\r

+Chapitre VIII\r
+\r
+Philosophie après boire\r
+\r
+\r
+Le sénateur dont il a été parlé plus haut était un homme entendu qui\r
+avait fait son chemin avec une rectitude inattentive à toutes ces\r
+rencontres qui font obstacle et qu'on nomme conscience, foi jurée,\r
+justice, devoir; il avait marché droit à son but et sans broncher une\r
+seule fois dans la ligne de son avancement et de son intérêt. C'était un\r
+ancien procureur, attendri par le succès, pas méchant homme du tout,\r
+rendant tous les petits services qu'il pouvait à ses fils, à ses\r
+gendres, à ses parents, même à des amis; ayant sagement pris de la vie\r
+les bons côtés, les bonnes occasions, les bonnes aubaines. Le reste lui\r
+semblait assez bête. Il était spirituel, et juste assez lettré pour se\r
+croire un disciple d'Épicure en n'étant peut-être qu'un produit de\r
+Pigault-Lebrun. Il riait volontiers, et agréablement, des choses\r
+infinies et éternelles, et des «billevesées du bonhomme évêque». Il en\r
+riait quelquefois, avec une aimable autorité, devant M. Myriel lui-même,\r
+qui écoutait.\r
+\r
+À je ne sais plus quelle cérémonie demi-officielle, le comte*** (ce\r
+sénateur) et M. Myriel durent dîner chez le préfet. Au dessert, le\r
+sénateur, un peu égayé, quoique toujours digne, s'écria:\r
+\r
+--Parbleu, monsieur l'évêque, causons. Un sénateur et un évêque se\r
+regardent difficilement sans cligner de l'oeil. Nous sommes deux\r
+augures. Je vais vous faire un aveu. J'ai ma philosophie.\r
+\r
+--Et vous avez raison, répondit l'évêque. Comme on fait sa philosophie\r
+on se couche. Vous êtes sur le lit de pourpre, monsieur le sénateur.\r
+\r
+Le sénateur, encouragé, reprit:\r
+\r
+--Soyons bons enfants.\r
+\r
+--Bons diables même, dit l'évêque.\r
+\r
+--Je vous déclare, reprit le sénateur, que le marquis d'Argens, Pyrrhon,\r
+Hobbes et M. Naigeon ne sont pas des maroufles. J'ai dans ma\r
+bibliothèque tous mes philosophes dorés sur tranche.\r
+\r
+--Comme vous-même, monsieur le comte, interrompit l'évêque.\r
+\r
+Le sénateur poursuivit:\r
+\r
+--Je hais Diderot; c'est un idéologue, un déclamateur et un\r
+révolutionnaire, au fond croyant en Dieu, et plus bigot que Voltaire.\r
+Voltaire s'est moqué de Needham, et il a eu tort; car les anguilles de\r
+Needham prouvent que Dieu est inutile. Une goutte de vinaigre dans une\r
+cuillerée de pâte de farine supplée le _fiat lux_. Supposez la goutte\r
+plus grosse et la cuillerée plus grande, vous avez le monde. L'homme,\r
+c'est l'anguille. Alors à quoi bon le Père éternel? Monsieur l'évêque,\r
+l'hypothèse Jéhovah me fatigue. Elle n'est bonne qu'à produire des gens\r
+maigres qui songent creux. À bas ce grand Tout qui me tracasse! Vive\r
+Zéro qui me laisse tranquille! De vous à moi, et pour vider mon sac, et\r
+pour me confesser à mon pasteur comme il convient, je vous avoue que\r
+j'ai du bon sens. Je ne suis pas fou de votre Jésus qui prêche à tout\r
+bout de champ le renoncement et le sacrifice. Conseil d'avare à des\r
+gueux. Renoncement! pourquoi? Sacrifice! à quoi? Je ne vois pas qu'un\r
+loup s'immole au bonheur d'un autre loup. Restons donc dans la nature.\r
+Nous sommes au sommet; ayons la philosophie supérieure. Que sert d'être\r
+en haut, si l'on ne voit pas plus loin que le bout du nez des autres?\r
+Vivons gaîment. La vie, c'est tout. Que l'homme ait un autre avenir,\r
+ailleurs, là-haut, là-bas, quelque part, je n'en crois pas un traître\r
+mot. Ah! l'on me recommande le sacrifice et le renoncement, je dois\r
+prendre garde à tout ce que je fais, il faut que je me casse la tête sur\r
+le bien et le mal, sur le juste et l'injuste, sur le _fas_ et le\r
+_nefas_. Pourquoi? parce que j'aurai à rendre compte de mes actions.\r
+Quand? après ma mort. Quel bon rêve! Après ma mort, bien fin qui me\r
+pincera. Faites donc saisir une poignée de cendre par une main d'ombre.\r
+Disons le vrai, nous qui sommes des initiés et qui avons levé la jupe\r
+d'Isis: il n'y a ni bien, ni mal; il y a de la végétation. Cherchons le\r
+réel. Creusons tout à fait. Allons au fond, que diable! Il faut flairer\r
+la vérité, fouiller sous terre, et la saisir. Alors elle vous donne des\r
+joies exquises. Alors vous devenez fort, et vous riez. Je suis carré par\r
+la base, moi. Monsieur l'évêque, l'immortalité de l'homme est un\r
+écoute-s'il-pleut. Oh! la charmante promesse! Fiez-vous-y. Le bon billet\r
+qu'a Adam! On est âme, on sera ange, on aura des ailes bleues aux\r
+omoplates. Aidez-moi donc, n'est-ce pas Tertullien qui dit que les\r
+bienheureux iront d'un astre à l'autre? Soit. On sera les sauterelles\r
+des étoiles. Et puis, on verra Dieu. Ta ta ta. Fadaises que tous ces\r
+paradis. Dieu est une sonnette monstre. Je ne dirais point cela dans le\r
+_Moniteur_, parbleu! mais je le chuchote entre amis. _Inter pocula_.\r
+Sacrifier la terre au paradis, c'est lâcher la proie pour l'ombre. Être\r
+dupe de l'infini! pas si bête. Je suis néant. Je m'appelle monsieur le\r
+comte Néant, sénateur. Étais-je avant ma naissance? Non. Serai-je après\r
+ma mort? Non. Que suis-je? un peu de poussière agrégée par un organisme.\r
+Qu'ai-je à faire sur cette terre? J'ai le choix. Souffrir ou jouir. Où\r
+me mènera la souffrance? Au néant. Mais j'aurai souffert. Où me mènera\r
+la jouissance? Au néant. Mais j'aurai joui. Mon choix est fait. Il faut\r
+être mangeant ou mangé. Je mange. Mieux vaut être la dent que l'herbe.\r
+Telle est ma sagesse. Après quoi, va comme je te pousse, le fossoyeur\r
+est là, le Panthéon pour nous autres, tout tombe dans le grand trou.\r
+Fin. _Finis_. Liquidation totale. Ceci est l'endroit de\r
+l'évanouissement. La mort est morte, croyez-moi. Qu'il y ait là\r
+quelqu'un qui ait quelque chose à me dire, je ris d'y songer. Invention\r
+de nourrices. Croquemitaine pour les enfants, Jéhovah pour les hommes.\r
+Non, notre lendemain est de la nuit. Derrière la tombe, il n'y a plus\r
+que des néants égaux. Vous avez été Sardanapale, vous avez été Vincent\r
+de Paul, cela fait le même rien. Voilà le vrai. Donc vivez, par-dessus\r
+tout. Usez de votre moi pendant que vous le tenez. En vérité, je vous le\r
+dis, monsieur l'évêque, j'ai ma philosophie, et j'ai mes philosophes. Je\r
+ne me laisse pas enguirlander par des balivernes. Après ça, il faut bien\r
+quelque chose à ceux qui sont en bas, aux va-nu-pieds, aux gagne-petit,\r
+aux misérables. On leur donne à gober les légendes, les chimères, l'âme,\r
+l'immortalité, le paradis, les étoiles. Ils mâchent cela. Ils le mettent\r
+sur leur pain sec. Qui n'a rien a le bon Dieu. C'est bien le moins. Je\r
+n'y fais point obstacle, mais je garde pour moi monsieur Naigeon. Le bon\r
+Dieu est bon pour le peuple.\r
+\r
+L'évêque battit des mains.\r
+\r
+--Voilà parler! s'écria-t-il. L'excellente chose, et vraiment\r
+merveilleuse, que ce matérialisme-là! Ne l'a pas qui veut. Ah! quand on\r
+l'a, on n'est plus dupe; on ne se laisse pas bêtement exiler comme\r
+Caton, ni lapider comme Étienne, ni brûler vif comme Jeanne d'Arc. Ceux\r
+qui ont réussi à se procurer ce matérialisme admirable ont la joie de se\r
+sentir irresponsables, et de penser qu'ils peuvent dévorer tout, sans\r
+inquiétude, les places, les sinécures, les dignités, le pouvoir bien ou\r
+mal acquis, les palinodies lucratives, les trahisons utiles, les\r
+savoureuses capitulations de conscience, et qu'ils entreront dans la\r
+tombe, leur digestion faite. Comme c'est agréable! Je ne dis pas cela\r
+pour vous, monsieur le sénateur. Cependant il m'est impossible de ne\r
+point vous féliciter. Vous autres grands seigneurs, vous avez, vous le\r
+dites, une philosophie à vous et pour vous, exquise, raffinée,\r
+accessible aux riches seuls, bonne à toutes les sauces, assaisonnant\r
+admirablement les voluptés de la vie. Cette philosophie est prise dans\r
+les profondeurs et déterrée par des chercheurs spéciaux. Mais vous êtes\r
+bons princes, et vous ne trouvez pas mauvais que la croyance au bon Dieu\r
+soit la philosophie du peuple, à peu près comme l'oie aux marrons est la\r
+dinde aux truffes du pauvre.\r

+Chapitre IX\r
+\r
+Le frère raconté par la soeur\r
+\r
+\r
+Pour donner une idée du ménage intérieur de M. l'évêque de Digne et de\r
+la façon dont ces deux saintes filles subordonnaient leurs actions,\r
+leurs pensées, même leurs instincts de femmes aisément effrayées, aux\r
+habitudes et aux intentions de l'évêque, sans qu'il eût même à prendre\r
+la peine de parler pour les exprimer, nous ne pouvons mieux faire que de\r
+transcrire ici une lettre de mademoiselle Baptistine à madame la\r
+vicomtesse de Boischevron, son amie d'enfance. Cette lettre est entre\r
+nos mains.\r
+\r
+«Digne, 16 décembre 18....\r
+\r
+«Ma bonne madame, pas un jour ne se passe sans que nous parlions de\r
+vous. C'est assez notre habitude, mais il y a une raison de plus.\r
+Figurez-vous qu'en lavant et époussetant les plafonds et les murs,\r
+madame Magloire a fait des découvertes; maintenant nos deux chambres\r
+tapissées de vieux papier blanchi à la chaux ne dépareraient pas un\r
+château dans le genre du vôtre. Madame Magloire a déchiré tout le\r
+papier. Il y avait des choses dessous. Mon salon, où il n'y a pas de\r
+meubles, et dont nous nous servons pour étendre le linge après les\r
+lessives, a quinze pieds de haut, dix-huit de large carrés, un plafond\r
+peint anciennement avec dorure, des solives comme chez vous. C'était\r
+recouvert d'une toile, du temps que c'était l'hôpital. Enfin des\r
+boiseries du temps de nos grand'mères. Mais c'est ma chambre qu'il faut\r
+voir. Madame Magloire a découvert, sous au moins dix papiers collés\r
+dessus, des peintures, sans être bonnes, qui peuvent se supporter. C'est\r
+Télémaque reçu chevalier par Minerve, c'est lui encore dans les jardins.\r
+Le nom m'échappe. Enfin où les dames romaines se rendaient une seule\r
+nuit. Que vous dirai-je? j'ai des romains, des romaines (_ici un mot\r
+illisible_), et toute la suite. Madame Magloire a débarbouillé tout\r
+cela, et cet été elle va réparer quelques petites avaries, revenir le\r
+tout, et ma chambre sera un vrai musée. Elle a trouvé aussi dans un coin\r
+du grenier deux consoles en bois, genre ancien. On demandait deux écus\r
+de six livres pour les redorer, mais il vaut bien mieux donner cela aux\r
+pauvres; d'ailleurs c'est fort laid, et j'aimerais mieux une table ronde\r
+en acajou.\r
+\r
+«Je suis toujours bien heureuse. Mon frère est si bon. Il donne tout ce\r
+qu'il a aux indigents et aux malades. Nous sommes très gênés. Le pays\r
+est dur l'hiver, et il faut bien faire quelque chose pour ceux qui\r
+manquent. Nous sommes à peu près chauffés et éclairés. Vous voyez que ce\r
+sont de grandes douceurs.\r
+\r
+«Mon frère a ses habitudes à lui. Quand il cause, il dit qu'un évêque\r
+doit être ainsi. Figurez-vous que la porte de la maison n'est jamais\r
+fermée. Entre qui veut, et l'on est tout de suite chez mon frère. Il ne\r
+craint rien, même la nuit. C'est là sa bravoure à lui, comme il dit.\r
+\r
+«Il ne veut pas que je craigne pour lui, ni que madame Magloire craigne.\r
+Il s'expose à tous les dangers, et il ne veut même pas que nous ayons\r
+l'air de nous en apercevoir. Il faut savoir le comprendre.\r
+\r
+«Il sort par la pluie, il marche dans l'eau, il voyage en hiver. Il n'a\r
+pas peur de la nuit, des routes suspectes ni des rencontres.\r
+\r
+«L'an dernier, il est allé tout seul dans un pays de voleurs. Il n'a pas\r
+voulu nous emmener. Il est resté quinze jours absent. À son retour, il\r
+n'avait rien eu, on le croyait mort, et il se portait bien, et il a dit:\r
+"Voilà comme on m'a volé!" Et il a ouvert une malle pleine de tous les\r
+bijoux de la cathédrale d'Embrun, que les voleurs lui avaient donnés.\r
+\r
+«Cette fois-là, en revenant, comme j'étais allée à sa rencontre à deux\r
+lieues avec d'autres de ses amis, je n'ai pu m'empêcher de le gronder un\r
+peu, en ayant soin de ne parler que pendant que la voiture faisait du\r
+bruit, afin que personne autre ne pût entendre.\r
+\r
+«Dans les premiers temps, je me disais: il n'y a pas de dangers qui\r
+l'arrêtent, il est terrible. À présent j'ai fini par m'y accoutumer. Je\r
+fais signe à madame Magloire pour qu'elle ne le contrarie pas. Il se\r
+risque comme il veut. Moi j'emmène madame Magloire, je rentre dans ma\r
+chambre, je prie pour lui, et je m'endors. Je suis tranquille, parce que\r
+je sais bien que s'il lui arrivait malheur, ce serait ma fin. Je m'en\r
+irais au bon Dieu avec mon frère et mon évêque. Madame Magloire a eu\r
+plus de peine que moi à s'habituer à ce qu'elle appelait ses\r
+imprudences. Mais à présent le pli est pris. Nous prions toutes les\r
+deux, nous avons peur ensemble, et nous nous endormons. Le diable\r
+entrerait dans la maison qu'on le laisserait faire. Après tout, que\r
+craignons-nous dans cette maison? Il y a toujours quelqu'un avec nous,\r
+qui est le plus fort. Le diable peut y passer, mais le bon Dieu\r
+l'habite.\r
+\r
+«Voilà qui me suffit. Mon frère n'a plus même besoin de me dire un mot\r
+maintenant. Je le comprends sans qu'il parle, et nous nous abandonnons à\r
+la Providence.\r
+\r
+«Voilà comme il faut être avec un homme qui a du grand dans l'esprit.\r
+\r
+«J'ai questionné mon frère pour le renseignement que vous me demandez\r
+sur la famille de Faux. Vous savez comme il sait tout et comme il a des\r
+souvenirs, car il est toujours très bon royaliste. C'est de vrai une\r
+très ancienne famille normande de la généralité de Caen. Il y a cinq\r
+cents ans d'un Raoul de Faux, d'un Jean de Faux et d'un Thomas de Faux,\r
+qui étaient des gentilshommes, dont un seigneur de Rochefort. Le dernier\r
+était Guy-Étienne-Alexandre, et était maître de camp, et quelque chose\r
+dans les chevaux-légers de Bretagne. Sa fille Marie-Louise a épousé\r
+Adrien-Charles de Gramont, fils du duc Louis de Gramont, pair de France,\r
+colonel des gardes françaises et lieutenant général des armées. On écrit\r
+Faux, Fauq et Faoucq.\r
+\r
+«Bonne madame, recommandez-nous aux prières de votre saint parent, M. le\r
+cardinal. Quant à votre chère Sylvanie, elle a bien fait de ne pas\r
+prendre les courts instants qu'elle passe près de vous pour m'écrire.\r
+Elle se porte bien, travaille selon vos désirs, m'aime toujours. C'est\r
+tout ce que je veux. Son souvenir par vous m'est arrivé. Je m'en trouve\r
+heureuse. Ma santé n'est pas trop mauvaise, et cependant je maigris tous\r
+les jours davantage. Adieu, le papier me manque et me force de vous\r
+quitter. Mille bonnes choses.\r
+\r
+«Baptistine.\r
+\r
+«P. S. Madame votre belle-soeur est toujours ici avec sa jeune famille.\r
+Votre petit-neveu est charmant. Savez-vous qu'il a cinq ans bientôt!\r
+Hier il a vu passer un cheval auquel on avait mis des genouillères, et\r
+il disait: "Qu'est-ce qu'il a donc aux genoux?" Il est si gentil, cet\r
+enfant! Son petit frère traîne un vieux balai dans l'appartement comme\r
+une voiture, et dit: "Hu!"\r
+\r
+»Comme on le voit par cette lettre, ces deux femmes savaient se plier\r
+aux façons d'être de l'évêque avec ce génie particulier de la femme qui\r
+comprend l'homme mieux que l'homme ne se comprend. L'évêque de Digne,\r
+sous cet air doux et candide qui ne se démentait jamais, faisait parfois\r
+des choses grandes, hardies et magnifiques, sans paraître même s'en\r
+douter. Elles en tremblaient, mais elles le laissaient faire.\r
+Quelquefois madame Magloire essayait une remontrance avant; jamais\r
+pendant ni après. Jamais on ne le troublait, ne fût-ce que par un signe,\r
+dans une action commencée. À de certains moments, sans qu'il eût besoin\r
+de le dire, lorsqu'il n'en avait peut-être pas lui-même conscience, tant\r
+sa simplicité était parfaite, elles sentaient vaguement qu'il agissait\r
+comme évêque; alors elles n'étaient plus que deux ombres dans la maison.\r
+Elles le servaient passivement, et, si c'était obéir que de disparaître,\r
+elles disparaissaient. Elles savaient, avec une admirable délicatesse\r
+d'instinct, que certaines sollicitudes peuvent gêner. Aussi, même le\r
+croyant en péril, elles comprenaient, je ne dis pas sa pensée, mais sa\r
+nature, jusqu'au point de ne plus veiller sur lui. Elles le confiaient à\r
+Dieu.\r
+\r
+D'ailleurs Baptistine disait, comme on vient de le lire, que la fin de\r
+son frère serait la sienne. Madame Magloire ne le disait pas, mais elle\r
+le savait.\r
+\r
+\r
+\r
+\r
+Chapitre X\r
+\r
+L'évêque en présence d'une lumière inconnue\r
+\r
+\r
+À une époque un peu postérieure à la date de la lettre citée dans les\r
+pages précédentes, il fit une chose, à en croire toute la ville, plus\r
+risquée encore que sa promenade à travers les montagnes des bandits. Il\r
+y avait près de Digne, dans la campagne, un homme qui vivait solitaire.\r
+Cet homme, disons tout de suite le gros mot, était un ancien\r
+conventionnel. Il se nommait G.\r
+\r
+On parlait du conventionnel G. dans le petit monde de Digne avec une\r
+sorte d'horreur. Un conventionnel, vous figurez-vous cela? Cela existait\r
+du temps qu'on se tutoyait et qu'on disait: citoyen. Cet homme était à\r
+peu près un monstre. Il n'avait pas voté la mort du roi, mais presque.\r
+C'était un quasi-régicide. Il avait été terrible. Comment, au retour des\r
+princes légitimes, n'avait-on pas traduit cet homme-là devant une cour\r
+prévôtale? On ne lui eût pas coupé la tête, si vous voulez, il faut de\r
+la clémence, soit; mais un bon bannissement à vie. Un exemple enfin!\r
+etc., etc. C'était un athée d'ailleurs, comme tous ces\r
+gens-là.--Commérages des oies sur le vautour.\r
+\r
+Était-ce du reste un vautour que G.? Oui, si l'on en jugeait par ce\r
+qu'il y avait de farouche dans sa solitude. N'ayant pas voté la mort du\r
+roi, il n'avait pas été compris dans les décrets d'exil et avait pu\r
+rester en France.\r
+\r
+Il habitait, à trois quarts d'heure de la ville, loin de tout hameau,\r
+loin de tout chemin, on ne sait quel repli perdu d'un vallon très\r
+sauvage. Il avait là, disait-on, une espèce de champ, un trou, un\r
+repaire. Pas de voisins; pas même de passants. Depuis qu'il demeurait\r
+dans ce vallon, le sentier qui y conduisait avait disparu sous l'herbe.\r
+On parlait de cet endroit-là comme de la maison du bourreau. Pourtant\r
+l'évêque songeait, et de temps en temps regardait l'horizon à l'endroit\r
+où un bouquet d'arbres marquait le vallon du vieux conventionnel, et il\r
+disait:\r
+\r
+--Il y a là une âme qui est seule.\r
+\r
+Et au fond de sa pensée il ajoutait: «Je lui dois ma visite.»\r
+\r
+Mais, avouons-le, cette idée, au premier abord naturelle, lui\r
+apparaissait, après un moment de réflexion, comme étrange et impossible,\r
+et presque repoussante. Car, au fond, il partageait l'impression\r
+générale, et le conventionnel lui inspirait, sans qu'il s'en rendît\r
+clairement compte, ce sentiment qui est comme la frontière de la haine\r
+et qu'exprime si bien le mot éloignement.\r
+\r
+Toutefois, la gale de la brebis doit-elle faire reculer le pasteur? Non.\r
+Mais quelle brebis!\r
+\r
+Le bon évêque était perplexe. Quelquefois il allait de ce côté-là, puis\r
+il revenait. Un jour enfin le bruit se répandit dans la ville qu'une\r
+façon de jeune pâtre qui servait le conventionnel G. dans sa bauge était\r
+venu chercher un médecin; que le vieux scélérat se mourait, que la\r
+paralysie le gagnait, et qu'il ne passerait pas la nuit.\r
+\r
+--Dieu merci! ajoutaient quelques-uns.\r
+\r
+L'évêque prit son bâton, mit son pardessus à cause de sa soutane un peu\r
+trop usée, comme nous l'avons dit, et aussi à cause du vent du soir qui\r
+ne devait pas tarder à souffler, et partit.\r
+\r
+Le soleil déclinait et touchait presque à l'horizon, quand l'évêque\r
+arriva à l'endroit excommunié. Il reconnut avec un certain battement de\r
+coeur qu'il était près de la tanière. Il enjamba un fossé, franchit une\r
+haie, leva un échalier, entra dans un courtil délabré, fit quelques pas\r
+assez hardiment, et tout à coup, au fond de la friche, derrière une\r
+haute broussaille, il aperçut la caverne.\r
+\r
+C'était une cabane toute basse, indigente, petite et propre, avec une\r
+treille clouée à la façade.\r
+\r
+Devant la porte, dans une vieille chaise à roulettes, fauteuil du\r
+paysan, il y avait un homme en cheveux blancs qui souriait au soleil.\r
+\r
+Près du vieillard assis se tenait debout un jeune garçon, le petit\r
+pâtre. Il tendait au vieillard une jatte de lait.\r
+\r
+Pendant que l'évêque regardait, le vieillard éleva la voix:\r
+\r
+--Merci, dit-il, je n'ai plus besoin de rien.\r
+\r
+Et son sourire quitta le soleil pour s'arrêter sur l'enfant.\r
+\r
+L'évêque s'avança. Au bruit qu'il fit en marchant, le vieux homme assis\r
+tourna la tête, et son visage exprima toute la quantité de surprise\r
+qu'on peut avoir après une longue vie.\r
+\r
+--Depuis que je suis ici, dit-il, voilà la première fois qu'on entre\r
+chez moi. Qui êtes-vous, monsieur?\r
+\r
+L'évêque répondit:\r
+\r
+--Je me nomme Bienvenu Myriel.\r
+\r
+--Bienvenu Myriel! j'ai entendu prononcer ce nom. Est-ce que c'est vous\r
+que le peuple appelle monseigneur Bienvenu?\r
+\r
+--C'est moi.\r
+\r
+Le vieillard reprit avec un demi-sourire:\r
+\r
+--En ce cas, vous êtes mon évêque?\r
+\r
+--Un peu.\r
+\r
+--Entrez, monsieur.\r
+\r
+Le conventionnel tendit la main à l'évêque, mais l'évêque ne la prit\r
+pas. L'évêque se borna à dire:\r
+\r
+--Je suis satisfait de voir qu'on m'avait trompé. Vous ne me semblez,\r
+certes, pas malade.\r
+\r
+--Monsieur, répondit le vieillard, je vais guérir.\r
+\r
+Il fit une pause et dit:\r
+\r
+--Je mourrai dans trois heures.\r
+\r
+Puis il reprit:\r
+\r
+--Je suis un peu médecin; je sais de quelle façon la dernière heure\r
+vient. Hier, je n'avais que les pieds froids; aujourd'hui, le froid a\r
+gagné les genoux; maintenant je le sens qui monte jusqu'à la ceinture;\r
+quand il sera au coeur, je m'arrêterai. Le soleil est beau, n'est-ce\r
+pas? je me suis fait rouler dehors pour jeter un dernier coup d'oeil sur\r
+les choses, vous pouvez me parler, cela ne me fatigue point. Vous faites\r
+bien de venir regarder un homme qui va mourir. Il est bon que ce\r
+moment-là ait des témoins. On a des manies; j'aurais voulu aller jusqu'à\r
+l'aube. Mais je sais que j'en ai à peine pour trois heures. Il fera\r
+nuit. Au fait, qu'importe! Finir est une affaire simple. On n'a pas\r
+besoin du matin pour cela. Soit. Je mourrai à la belle étoile.\r
+\r
+Le vieillard se tourna vers le pâtre.\r
+\r
+--Toi, va te coucher. Tu as veillé l'autre nuit. Tu es fatigué.\r
+\r
+L'enfant rentra dans la cabane.\r
+\r
+Le vieillard le suivit des yeux et ajouta comme se parlant à lui-même:\r
+\r
+--Pendant qu'il dormira, je mourrai. Les deux sommeils peuvent faire bon\r
+voisinage.\r
+\r
+L'évêque n'était pas ému comme il semble qu'il aurait pu l'être. Il ne\r
+croyait pas sentir Dieu dans cette façon de mourir. Disons tout, car les\r
+petites contradictions des grands coeurs veulent être indiquées comme le\r
+reste, lui qui, dans l'occasion, riait si volontiers de Sa Grandeur, il\r
+était quelque peu choqué de ne pas être appelé monseigneur, et il était\r
+presque tenté de répliquer: citoyen. Il lui vint une velléité de\r
+familiarité bourrue, assez ordinaire aux médecins et aux prêtres, mais\r
+qui ne lui était pas habituelle, à lui. Cet homme, après tout, ce\r
+conventionnel, ce représentant du peuple, avait été un puissant de la\r
+terre; pour la première fois de sa vie peut-être, l'évêque se sentit en\r
+humeur de sévérité.\r
+\r
+Le conventionnel cependant le considérait avec une cordialité modeste,\r
+où l'on eût pu démêler l'humilité qui sied quand on est si près de sa\r
+mise en poussière.\r
+\r
+L'évêque, de son côté, quoiqu'il se gardât ordinairement de la\r
+curiosité, laquelle, selon lui, était contiguë à l'offense, ne pouvait\r
+s'empêcher d'examiner le conventionnel avec une attention qui, n'ayant\r
+pas sa source dans la sympathie, lui eût été probablement reprochée par\r
+sa conscience vis-à-vis de tout autre homme. Un conventionnel lui\r
+faisait un peu l'effet d'être hors la loi, même hors la loi de charité.\r
+\r
+G., calme, le buste presque droit, la voix vibrante, était un de ces\r
+grands octogénaires qui font l'étonnement du physiologiste. La\r
+révolution a eu beaucoup de ces hommes proportionnés à l'époque. On\r
+sentait dans ce vieillard l'homme à l'épreuve. Si près de sa fin, il\r
+avait conservé tous les gestes de la santé. Il y avait dans son coup\r
+d'oeil clair, dans son accent ferme, dans son robuste mouvement\r
+d'épaules, de quoi déconcerter la mort. Azraël, l'ange mahométan du\r
+sépulcre, eût rebroussé chemin et eût cru se tromper de porte. G.\r
+semblait mourir parce qu'il le voulait bien. Il y avait de la liberté\r
+dans son agonie. Les jambes seulement étaient immobiles. Les ténèbres le\r
+tenaient par là. Les pieds étaient morts et froids, et la tête vivait de\r
+toute la puissance de la vie et paraissait en pleine lumière. G., en ce\r
+grave moment, ressemblait à ce roi du conte oriental, chair par en haut,\r
+marbre par en bas.\r
+\r
+Une pierre était là. L'évêque s'y assit. L'exorde fut _ex abrupto_.\r
+\r
+--Je vous félicite, dit-il du ton dont on réprimande. Vous n'avez\r
+toujours pas voté la mort du roi.\r
+\r
+Le conventionnel ne parut pas remarquer le sous-entendu amer caché dans\r
+ce mot: toujours. Il répondit. Tout sourire avait disparu de sa face.\r
+\r
+--Ne me félicitez pas trop, monsieur; j'ai voté la fin du tyran.\r
+\r
+C'était l'accent austère en présence de l'accent sévère.\r
+\r
+--Que voulez-vous dire? reprit l'évêque.\r
+\r
+--Je veux dire que l'homme a un tyran, l'ignorance. J'ai voté la fin de\r
+ce tyran-là. Ce tyran-là a engendré la royauté qui est l'autorité prise\r
+dans le faux, tandis que la science est l'autorité prise dans le vrai.\r
+L'homme ne doit être gouverné que par la science.\r
+\r
+--Et la conscience, ajouta l'évêque.\r
+\r
+--C'est la même chose. La conscience, c'est la quantité de science innée\r
+que nous avons en nous.\r
+\r
+Monseigneur Bienvenu écoutait, un peu étonné, ce langage très nouveau\r
+pour lui. Le conventionnel poursuivit:\r
+\r
+--Quant à Louis XVI, j'ai dit non. Je ne me crois pas le droit de tuer\r
+un homme; mais je me sens le devoir d'exterminer le mal. J'ai voté la\r
+fin du tyran. C'est-à-dire la fin de la prostitution pour la femme, la\r
+fin de l'esclavage pour l'homme, la fin de la nuit pour l'enfant. En\r
+votant la république, j'ai voté cela. J'ai voté la fraternité, la\r
+concorde, l'aurore! J'ai aidé à la chute des préjugés et des erreurs.\r
+Les écroulements des erreurs et des préjugés font de la lumière. Nous\r
+avons fait tomber le vieux monde, nous autres, et le vieux monde, vase\r
+des misères, en se renversant sur le genre humain, est devenu une urne\r
+de joie.\r
+\r
+--Joie mêlée, dit l'évêque.\r
+\r
+--Vous pourriez dire joie troublée, et aujourd'hui, après ce fatal\r
+retour du passé qu'on nomme 1814, joie disparue. Hélas, l'oeuvre a été\r
+incomplète, j'en conviens; nous avons démoli l'ancien régime dans les\r
+faits, nous n'avons pu entièrement le supprimer dans les idées. Détruire\r
+les abus, cela ne suffit pas; il faut modifier les moeurs. Le moulin n'y\r
+est plus, le vent y est encore.\r
+\r
+--Vous avez démoli. Démolir peut être utile; mais je me défie d'une\r
+démolition compliquée de colère.\r
+\r
+--Le droit a sa colère, monsieur l'évêque, et la colère du droit est un\r
+élément du progrès. N'importe, et quoi qu'on en dise, la révolution\r
+française est le plus puissant pas du genre humain depuis l'avènement du\r
+Christ. Incomplète, soit; mais sublime. Elle a dégagé toutes les\r
+inconnues sociales. Elle a adouci les esprits; elle a calmé, apaisé,\r
+éclairé; elle a fait couler sur la terre des flots de civilisation. Elle\r
+a été bonne. La révolution française, c'est le sacre de l'humanité.\r
+\r
+L'évêque ne put s'empêcher de murmurer:\r
+\r
+--Oui? 93!\r
+\r
+Le conventionnel se dressa sur sa chaise avec une solennité presque\r
+lugubre, et, autant qu'un mourant peut s'écrier, il s'écria:\r
+\r
+--Ah! vous y voilà! 93! J'attendais ce mot-là. Un nuage s'est formé\r
+pendant quinze cents ans. Au bout de quinze siècles, il a crevé. Vous\r
+faites le procès au coup de tonnerre.\r
+\r
+L'évêque sentit, sans se l'avouer peut-être, que quelque chose en lui\r
+était atteint. Pourtant il fit bonne contenance. Il répondit:\r
+\r
+--Le juge parle au nom de la justice; le prêtre parle au nom de la\r
+pitié, qui n'est autre chose qu'une justice plus élevée. Un coup de\r
+tonnerre ne doit pas se tromper.\r
+\r
+Et il ajouta en regardant fixement le conventionnel.\r
+\r
+--Louis XVII?\r
+\r
+Le conventionnel étendit la main et saisit le bras de l'évêque:\r
+\r
+--Louis XVII! Voyons, sur qui pleurez-vous? Est-ce sur l'enfant\r
+innocent? alors, soit. Je pleure avec vous. Est-ce sur l'enfant royal?\r
+je demande à réfléchir. Pour moi, le frère de Cartouche, enfant\r
+innocent, pendu sous les aisselles en place de Grève jusqu'à ce que mort\r
+s'ensuive, pour le seul crime d'avoir été le frère de Cartouche, n'est\r
+pas moins douloureux que le petit-fils de Louis XV, enfant innocent,\r
+martyrisé dans la tour du Temple pour le seul crime d'avoir été le\r
+petit-fils de Louis XV.\r
+\r
+--Monsieur, dit l'évêque, je n'aime pas ces rapprochements de noms.\r
+\r
+--Cartouche? Louis XV? pour lequel des deux réclamez-vous?\r
+\r
+Il y eut un moment de silence. L'évêque regrettait presque d'être venu,\r
+et pourtant il se sentait vaguement et étrangement ébranlé.\r
+\r
+Le conventionnel reprit:\r
+\r
+--Ah! monsieur le prêtre, vous n'aimez pas les crudités du vrai. Christ\r
+les aimait, lui. Il prenait une verge et il époussetait le temple. Son\r
+fouet plein d'éclairs était un rude diseur de vérités. Quand il\r
+s'écriait: _Sinite parvulos_..., il ne distinguait pas entre les petits\r
+enfants. Il ne se fût pas gêné de rapprocher le dauphin de Barabbas du\r
+dauphin d'Hérode. Monsieur, l'innocence est sa couronne à elle-même.\r
+L'innocence n'a que faire d'être altesse. Elle est aussi auguste\r
+déguenillée que fleurdelysée.\r
+\r
+--C'est vrai, dit l'évêque à voix basse.\r
+\r
+--J'insiste, continua le conventionnel G. Vous m'avez nommé Louis XVII.\r
+Entendons-nous. Pleurons-nous sur tous les innocents, sur tous les\r
+martyrs, sur tous les enfants, sur ceux d'en bas comme sur ceux d'en\r
+haut? J'en suis. Mais alors, je vous l'ai dit, il faut remonter plus\r
+haut que 93, et c'est avant Louis XVII qu'il faut commencer nos larmes.\r
+Je pleurerai sur les enfants des rois avec vous, pourvu que vous\r
+pleuriez avec moi sur les petits du peuple.\r
+\r
+--Je pleure sur tous, dit l'évêque.\r
+\r
+--Également! s'écria G., et si la balance doit pencher, que ce soit du\r
+côté du peuple. Il y a plus longtemps qu'il souffre.\r
+\r
+Il y eut encore un silence. Ce fut le conventionnel qui le rompit. Il se\r
+souleva sur un coude, prit entre son pouce et son index replié un peu de\r
+sa joue, comme on fait machinalement lorsqu'on interroge et qu'on juge,\r
+et interpella l'évêque avec un regard plein de toutes les énergies de\r
+l'agonie. Ce fut presque une explosion.\r
+\r
+--Oui, monsieur, il y a longtemps que le peuple souffre. Et puis, tenez,\r
+ce n'est pas tout cela, que venez-vous me questionner et me parler de\r
+Louis XVII? Je ne vous connais pas, moi. Depuis que je suis dans ce\r
+pays, j'ai vécu dans cet enclos, seul, ne mettant pas les pieds dehors,\r
+ne vient personne que cet enfant qui m'aide. Votre nom est, il est vrai,\r
+arrivé confusément jusqu'à moi, et, je dois le dire, pas très mal\r
+prononcé; mais cela ne signifie rien; les gens habiles ont tant de\r
+manières d'en faire accroire à ce brave bonhomme de peuple. À propos, je\r
+n'ai pas entendu le bruit de votre voiture, vous l'aurez sans doute\r
+laissée derrière le taillis, là-bas, à l'embranchement de la route. Je\r
+ne vous connais pas, vous dis-je. Vous m'avez dit que vous étiez\r
+l'évêque, mais cela ne me renseigne point sur votre personne morale. En\r
+somme, je vous répète ma question. Qui êtes-vous? Vous êtes un évêque,\r
+c'est-à-dire un prince de l'église, un de ces hommes dorés, armoriés,\r
+rentés, qui ont de grosses prébendes--l'évêché de Digne, quinze mille\r
+francs de fixe, dix mille francs de casuel, total, vingt-cinq mille\r
+francs--, qui ont des cuisines, qui ont des livrées, qui font bonne\r
+chère, qui mangent des poules d'eau le vendredi, qui se pavanent,\r
+laquais devant, laquais derrière, en berline de gala, et qui ont des\r
+palais, et qui roulent carrosse au nom de Jésus-Christ qui allait pieds\r
+nus! Vous êtes un prélat; rentes, palais, chevaux, valets, bonne table,\r
+toutes les sensualités de la vie, vous avez cela comme les autres, et\r
+comme les autres vous en jouissez, c'est bien, mais cela en dit trop ou\r
+pas assez; cela ne m'éclaire pas sur votre valeur intrinsèque et\r
+essentielle, à vous qui venez avec la prétention probable de m'apporter\r
+de la sagesse. À qui est-ce que je parle? Qui êtes-vous?\r
+\r
+L'évêque baissa la tête et répondit:\r
+\r
+--_Vermis sum_.\r
+\r
+--Un ver de terre en carrosse! grommela le conventionnel.\r
+\r
+C'était le tour du conventionnel d'être hautain, et de l'évêque d'être\r
+humble.\r
+\r
+L'évêque reprit avec douceur.\r
+\r
+--Monsieur, soit. Mais expliquez-moi en quoi mon carrosse, qui est là à\r
+deux pas derrière les arbres, en quoi ma bonne table et les poules d'eau\r
+que je mange le vendredi, en quoi mes vingt-cinq mille livres de rentes,\r
+en quoi mon palais et mes laquais prouvent que la pitié n'est pas une\r
+vertu, que la clémence n'est pas un devoir, et que 93 n'a pas été\r
+inexorable.\r
+\r
+Le conventionnel passa la main sur son front comme pour en écarter un\r
+nuage.\r
+\r
+--Avant de vous répondre, dit-il, je vous prie de me pardonner. Je viens\r
+d'avoir un tort, monsieur. Vous êtes chez moi, vous êtes mon hôte. Je\r
+vous dois courtoisie. Vous discutez mes idées, il sied que je me borne à\r
+combattre vos raisonnements. Vos richesses et vos jouissances sont des\r
+avantages que j'ai contre vous dans le débat, mais il est de bon goût de\r
+ne pas m'en servir. Je vous promets de ne plus en user.\r
+\r
+--Je vous remercie, dit l'évêque.\r
+\r
+G. reprit:\r
+\r
+--Revenons à l'explication que vous me demandiez. Où en étions-nous? Que\r
+me disiez-vous? que 93 a été inexorable?\r
+\r
+--Inexorable, oui, dit l'évêque. Que pensez-vous de Marat battant des\r
+mains à la guillotine?\r
+\r
+--Que pensez-vous de Bossuet chantant le _Te Deum_ sur les dragonnades?\r
+\r
+La réponse était dure, mais elle allait au but avec la rigidité d'une\r
+pointe d'acier. L'évêque en tressaillit; il ne lui vint aucune riposte,\r
+mais il était froissé de cette façon de nommer Bossuet. Les meilleurs\r
+esprits ont leurs fétiches, et parfois se sentent vaguement meurtris des\r
+manques de respect de la logique.\r
+\r
+Le conventionnel commençait à haleter; l'asthme de l'agonie, qui se mêle\r
+aux derniers souffles, lui entrecoupait la voix; cependant il avait\r
+encore une parfaite lucidité d'âme dans les yeux. Il continua:\r
+\r
+--Disons encore quelques mots çà et là, je veux bien. En dehors de la\r
+révolution qui, prise dans son ensemble, est une immense affirmation\r
+humaine, 93, hélas! est une réplique. Vous le trouvez inexorable, mais\r
+toute la monarchie, monsieur? Carrier est un bandit; mais quel nom\r
+donnez-vous à Montrevel? Fouquier-Tinville est un gueux, mais quel est\r
+votre avis sur Lamoignon-Bâville? Maillard est affreux, mais\r
+Saulx-Tavannes, s'il vous plaît? Le père Duchêne est féroce, mais quelle\r
+épithète m'accorderez-vous pour le père Letellier? Jourdan-Coupe-Tête\r
+est un monstre, mais moindre que M. le marquis de Louvois. Monsieur,\r
+monsieur, je plains Marie-Antoinette, archiduchesse et reine, mais je\r
+plains aussi cette pauvre femme huguenote qui, en 1685, sous Louis le\r
+Grand, monsieur, allaitant son enfant, fut liée, nue jusqu'à la\r
+ceinture, à un poteau, l'enfant tenu à distance; le sein se gonflait de\r
+lait et le coeur d'angoisse. Le petit, affamé et pâle, voyait ce sein,\r
+agonisait et criait, et le bourreau disait à la femme, mère et nourrice:\r
+«Abjure!» lui donnant à choisir entre la mort de son enfant et la mort\r
+de sa conscience. Que dites-vous de ce supplice de Tantale accommodé à\r
+une mère? Monsieur, retenez bien ceci: la révolution française a eu ses\r
+raisons. Sa colère sera absoute par l'avenir. Son résultat, c'est le\r
+monde meilleur. De ses coups les plus terribles, il sort une caresse\r
+pour le genre humain. J'abrège. Je m'arrête, j'ai trop beau jeu.\r
+D'ailleurs je me meurs.\r
+\r
+Et, cessant de regarder l'évêque, le conventionnel acheva sa pensée en\r
+ces quelques mots tranquilles:\r
+\r
+--Oui, les brutalités du progrès s'appellent révolutions. Quand elles\r
+sont finies, on reconnaît ceci: que le genre humain a été rudoyé, mais\r
+qu'il a marché.\r
+\r
+Le conventionnel ne se doutait pas qu'il venait d'emporter\r
+successivement l'un après l'autre tous les retranchements intérieurs de\r
+l'évêque. Il en restait un pourtant, et de ce retranchement, suprême\r
+ressource de la résistance de monseigneur Bienvenu, sortit cette parole\r
+où reparut presque toute la rudesse du commencement:\r
+\r
+--Le progrès doit croire en Dieu. Le bien ne peut pas avoir de serviteur\r
+impie. C'est un mauvais conducteur du genre humain que celui qui est\r
+athée.\r
+\r
+Le vieux représentant du peuple ne répondit pas. Il eut un tremblement.\r
+Il regarda le ciel, et une larme germa lentement dans ce regard. Quand\r
+la paupière fut pleine, la larme coula le long de sa joue livide, et il\r
+dit presque en bégayant, bas et se parlant à lui-même, l'oeil perdu dans\r
+les profondeurs:\r
+\r
+--O toi! ô idéal! toi seul existes!\r
+\r
+L'évêque eut une sorte d'inexprimable commotion. Après un silence, le\r
+vieillard leva un doigt vers le ciel, et dit:\r
+\r
+--L'infini est. Il est là. Si l'infini n'avait pas de moi, le moi serait\r
+sa borne; il ne serait pas infini; en d'autres termes, il ne serait pas.\r
+Or il est. Donc il a un moi. Ce moi de l'infini, c'est Dieu.\r
+\r
+Le mourant avait prononcé ces dernières paroles d'une voix haute et avec\r
+le frémissement de l'extase, comme s'il voyait quelqu'un. Quand il eut\r
+parlé, ses yeux se fermèrent. L'effort l'avait épuisé. Il était évident\r
+qu'il venait de vivre en une minute les quelques heures qui lui\r
+restaient. Ce qu'il venait de dire l'avait approché de celui qui est\r
+dans la mort. L'instant suprême arrivait.\r
+\r
+L'évêque le comprit, le moment pressait, c'était comme prêtre qu'il\r
+était venu; de l'extrême froideur, il était passé par degrés à l'émotion\r
+extrême; il regarda ces yeux fermés, il prit cette vieille main ridée et\r
+glacée, et se pencha vers le moribond:\r
+\r
+--Cette heure est celle de Dieu. Ne trouvez-vous pas qu'il serait\r
+regrettable que nous nous fussions rencontrés en vain?\r
+\r
+Le conventionnel rouvrit les yeux. Une gravité où il y avait de l'ombre\r
+s'empreignit sur son visage.\r
+\r
+--Monsieur l'évêque, dit-il, avec une lenteur qui venait peut-être plus\r
+encore de la dignité de l'âme que de la défaillance des forces, j'ai\r
+passé ma vie dans la méditation, l'étude et la contemplation. J'avais\r
+soixante ans quand mon pays m'a appelé, et m'a ordonné de me mêler de\r
+ses affaires. J'ai obéi. Il y avait des abus, je les ai combattus; il y\r
+avait des tyrannies, je les ai détruites; il y avait des droits et des\r
+principes, je les ai proclamés et confessés. Le territoire était envahi,\r
+je l'ai défendu; la France était menacée, j'ai offert ma poitrine. Je\r
+n'étais pas riche; je suis pauvre. J'ai été l'un des maîtres de l'État,\r
+les caves du Trésor étaient encombrées d'espèces au point qu'on était\r
+forcé d'étançonner les murs, prêts à se fendre sous le poids de l'or et\r
+de l'argent, je dînais rue de l'Arbre-Sec à vingt-deux sous par tête.\r
+J'ai secouru les opprimés, j'ai soulagé les souffrants. J'ai déchiré la\r
+nappe de l'autel, c'est vrai; mais c'était pour panser les blessures de\r
+la patrie. J'ai toujours soutenu la marche en avant du genre humain vers\r
+la lumière, et j'ai résisté quelquefois au progrès sans pitié. J'ai,\r
+dans l'occasion, protégé mes propres adversaires, vous autres. Et il y a\r
+à Peteghem en Flandre, à l'endroit même où les rois mérovingiens avaient\r
+leur palais d'été, un couvent d'urbanistes, l'abbaye de Sainte-Claire en\r
+Beaulieu, que j'ai sauvé en 1793. J'ai fait mon devoir selon mes forces,\r
+et le bien que j'ai pu. Après quoi j'ai été chassé, traqué, poursuivi,\r
+persécuté, noirci, raillé, conspué, maudit, proscrit. Depuis bien des\r
+années déjà, avec mes cheveux blancs, je sens que beaucoup de gens se\r
+croient sur moi le droit de mépris, j'ai pour la pauvre foule ignorante\r
+visage de damné, et j'accepte, ne haïssant personne, l'isolement de la\r
+haine. Maintenant, j'ai quatre-vingt-six ans; je vais mourir. Qu'est-ce\r
+que vous venez me demander?\r
+\r
+--Votre bénédiction, dit l'évêque.\r
+\r
+Et il s'agenouilla.\r
+\r
+Quand l'évêque releva la tête, la face du conventionnel était devenue\r
+auguste. Il venait d'expirer.\r
+\r
+L'évêque rentra chez lui profondément absorbé dans on ne sait quelles\r
+pensées. Il passa toute la nuit en prière. Le lendemain, quelques braves\r
+curieux essayèrent de lui parler du conventionnel G.; il se borna à\r
+montrer le ciel. À partir de ce moment, il redoubla de tendresse et de\r
+fraternité pour les petits et les souffrants.\r
+\r
+Toute allusion à ce «vieux scélérat de G.» le faisait tomber dans une\r
+préoccupation singulière. Personne ne pourrait dire que le passage de\r
+cet esprit devant le sien et le reflet de cette grande conscience sur la\r
+sienne ne fût pas pour quelque chose dans son approche de la perfection.\r
+\r
+Cette «visite pastorale» fut naturellement une occasion de bourdonnement\r
+pour les petites coteries locales:\r
+\r
+--Était-ce la place d'un évêque que le chevet d'un tel mourant? Il n'y\r
+avait évidemment pas de conversion à attendre. Tous ces révolutionnaires\r
+sont relaps. Alors pourquoi y aller? Qu'a-t-il été regarder là? Il\r
+fallait donc qu'il fût bien curieux d'un emportement d'âme par le\r
+diable.\r
+\r
+Un jour, une douairière, de la variété impertinente qui se croit\r
+spirituelle, lui adressa cette saillie:\r
+\r
+--Monseigneur, on demande quand Votre Grandeur aura le bonnet rouge.\r
+\r
+--Oh! oh! voilà une grosse couleur, répondit l'évêque. Heureusement que\r
+ceux qui la méprisent dans un bonnet la vénèrent dans un chapeau.\r

+Chapitre XI\r
+\r
+Une restriction\r
+\r
+\r
+On risquerait fort de se tromper si l'on concluait de là que monseigneur\r
+Bienvenu fût «un évêque philosophe» ou «un curé patriote». Sa rencontre,\r
+ce qu'on pourrait presque appeler sa conjonction avec le conventionnel\r
+G., lui laissa une sorte d'étonnement qui le rendit plus doux encore.\r
+Voilà tout.\r
+\r
+Quoique monseigneur Bienvenu n'ait été rien moins qu'un homme politique,\r
+c'est peut-être ici le lieu d'indiquer, très brièvement, quelle fut son\r
+attitude dans les événements d'alors, en supposant que monseigneur\r
+Bienvenu ait jamais songé à avoir une attitude. Remontons donc en\r
+arrière de quelques années.\r
+\r
+Quelque temps après l'élévation de M. Myriel à l'épiscopat, l'empereur\r
+l'avait fait baron de l'empire, en même temps que plusieurs autres\r
+évêques. L'arrestation du pape eut lieu, comme on sait, dans la nuit du\r
+5 au 6 juillet 1809; à cette occasion, M. Myriel fut appelé par Napoléon\r
+au synode des évêques de France et d'Italie convoqué à Paris. Ce synode\r
+se tint à Notre-Dame et s'assembla pour la première fois le 15 juin 1811\r
+sous la présidence de M. le cardinal Fesch. M. Myriel fut du nombre des\r
+quatre-vingt-quinze évêques qui s'y rendirent. Mais il n'assista qu'à\r
+une séance et à trois ou quatre conférences particulières. Évêque d'un\r
+diocèse montagnard, vivant si près de la nature, dans la rusticité et le\r
+dénuement, il paraît qu'il apportait parmi ces personnages éminents des\r
+idées qui changeaient la température de l'assemblée. Il revint bien vite\r
+à Digne. On le questionna sur ce prompt retour, il répondit:\r
+\r
+--Je les gênais. L'air du dehors leur venait par moi. Je leur faisais\r
+l'effet d'une porte ouverte.\r
+\r
+Une autre fois il dit:\r
+\r
+--Que voulez-vous? ces messeigneurs-là sont des princes. Moi, je ne suis\r
+qu'un pauvre évêque paysan.\r
+\r
+Le fait est qu'il avait déplu. Entre autres choses étranges, il lui\r
+serait échappé de dire, un soir qu'il se trouvait chez un de ses\r
+collègues les plus qualifiés:\r
+\r
+--Les belles pendules! les beaux tapis! les belles livrées! Ce doit être\r
+bien importun! Oh! que je ne voudrais pas avoir tout ce superflu-là à me\r
+crier sans cesse aux oreilles: Il y a des gens qui ont faim! il y a des\r
+gens qui ont froid! il y a des pauvres! il y a des pauvres!\r
+\r
+Disons-le en passant, ce ne serait pas une haine intelligente que la\r
+haine du luxe. Cette haine impliquerait la haine des arts. Cependant,\r
+chez les gens d'église, en dehors de la représentation et des\r
+cérémonies, le luxe est un tort. Il semble révéler des habitudes peu\r
+réellement charitables. Un prêtre opulent est un contre-sens. Le prêtre\r
+doit se tenir près des pauvres. Or peut-on toucher sans cesse, et nuit\r
+et jour, à toutes les détresses, à toutes les infortunes, à toutes les\r
+indigences, sans avoir soi-même sur soi un peu de cette sainte misère,\r
+comme la poussière du travail? Se figure-t-on un homme qui est près d'un\r
+brasier, et qui n'a pas chaud? Se figure-t-on un ouvrier qui travaille\r
+sans cesse à une fournaise, et qui n'a ni un cheveu brûlé, ni un ongle\r
+noirci, ni une goutte de sueur, ni un grain de cendre au visage? La\r
+première preuve de la charité chez le prêtre, chez l'évêque surtout,\r
+c'est la pauvreté. C'était là sans doute ce que pensait M. l'évêque de\r
+Digne.\r
+\r
+Il ne faudrait pas croire d'ailleurs qu'il partageait sur certains\r
+points délicats ce que nous appellerions «les idées du siècle». Il se\r
+mêlait peu aux querelles théologiques du moment et se taisait sur les\r
+questions où sont compromis l'Église et l'État; mais si on l'eût\r
+beaucoup pressé, il paraît qu'on l'eût trouvé plutôt ultramontain que\r
+gallican. Comme nous faisons un portrait et que nous ne voulons rien\r
+cacher, nous sommes forcé d'ajouter qu'il fut glacial pour Napoléon\r
+déclinant. À partir de 1813, il adhéra ou il applaudit à toutes les\r
+manifestations hostiles. Il refusa de le voir à son passage au retour de\r
+l'île d'Elbe, et s'abstint d'ordonner dans son diocèse les prières\r
+publiques pour l'empereur pendant les Cent-Jours.\r
+\r
+Outre sa soeur, mademoiselle Baptistine, il avait deux frères: l'un\r
+général, l'autre préfet. Il écrivait assez souvent à tous les deux. Il\r
+tint quelque temps rigueur au premier, parce qu'ayant un commandement en\r
+Provence, à l'époque du débarquement de Cannes, le général s'était mis à\r
+la tête de douze cents hommes et avait poursuivi l'empereur comme\r
+quelqu'un qui veut le laisser échapper. Sa correspondance resta plus\r
+affectueuse pour l'autre frère, l'ancien préfet, brave et digne homme\r
+qui vivait retiré à Paris, rue Cassette.\r
+\r
+Monseigneur Bienvenu eut donc, aussi lui, son heure d'esprit de parti,\r
+son heure d'amertume, son nuage. L'ombre des passions du moment traversa\r
+ce doux et grand esprit occupé des choses éternelles. Certes, un pareil\r
+homme eût mérité de n'avoir pas d'opinions politiques. Qu'on ne se\r
+méprenne pas sur notre pensée, nous ne confondons point ce qu'on appelle\r
+«opinions politiques» avec la grande aspiration au progrès, avec la\r
+sublime foi patriotique, démocratique et humaine, qui, de nos jours,\r
+doit être le fond même de toute intelligence généreuse. Sans approfondir\r
+des questions qui ne touchent qu'indirectement au sujet de ce livre,\r
+nous disons simplement ceci: Il eût été beau que monseigneur Bienvenu\r
+n'eût pas été royaliste et que son regard ne se fût pas détourné un seul\r
+instant de cette contemplation sereine où l'on voit rayonner\r
+distinctement, au-dessus du va-et-vient orageux des choses humaines, ces\r
+trois pures lumières, la Vérité, la Justice, la Charité.\r
+\r
+Tout en convenant que ce n'était point pour une fonction politique que\r
+Dieu avait créé monseigneur Bienvenu, nous eussions compris et admiré la\r
+protestation au nom du droit et de la liberté, l'opposition fière, la\r
+résistance périlleuse et juste à Napoléon tout-puissant. Mais ce qui\r
+nous plaît vis-à-vis de ceux qui montent nous plaît moins vis-à-vis de\r
+ceux qui tombent. Nous n'aimons le combat que tant qu'il y a danger; et,\r
+dans tous les cas, les combattants de la première heure ont seuls le\r
+droit d'être les exterminateurs de la dernière. Qui n'a pas été\r
+accusateur opiniâtre pendant la prospérité doit se taire devant\r
+l'écroulement. Le dénonciateur du succès est le seul légitime justicier\r
+de la chute. Quant à nous, lorsque la Providence s'en mêle et frappe,\r
+nous la laissons faire. 1812 commence à nous désarmer. En 1813, la lâche\r
+rupture de silence de ce corps législatif taciturne enhardi par les\r
+catastrophes n'avait que de quoi indigner, et c'était un tort\r
+d'applaudir; en 1814, devant ces maréchaux trahissant, devant ce sénat\r
+passant d'une fange à l'autre, insultant après avoir divinisé, devant\r
+cette idolâtrie lâchant pied et crachant sur l'idole, c'était un devoir\r
+de détourner la tête; en 1815, comme les suprêmes désastres étaient dans\r
+l'air, comme la France avait le frisson de leur approche sinistre, comme\r
+on pouvait vaguement distinguer Waterloo ouvert devant Napoléon, la\r
+douloureuse acclamation de l'armée et du peuple au condamné du destin\r
+n'avait rien de risible, et, toute réserve faite sur le despote, un\r
+coeur comme l'évêque de Digne n'eût peut-être pas dû méconnaître ce\r
+qu'avait d'auguste et de touchant, au bord de l'abîme, l'étroit\r
+embrassement d'une grande nation et d'un grand homme.\r
+\r
+À cela près, il était et il fut, en toute chose, juste, vrai, équitable,\r
+intelligent, humble et digne; bienfaisant, et bienveillant, ce qui est\r
+une autre bienfaisance. C'était un prêtre, un sage, et un homme. Même,\r
+il faut le dire, dans cette opinion politique que nous venons de lui\r
+reprocher et que nous sommes disposé à juger presque sévèrement, il\r
+était tolérant et facile, peut-être plus que nous qui parlons ici.--Le\r
+portier de la maison de ville avait été placé là par l'empereur. C'était\r
+un vieux sous-officier de la vieille garde, légionnaire d'Austerlitz,\r
+bonapartiste comme l'aigle. Il échappait dans l'occasion à ce pauvre\r
+diable de ces paroles peu réfléchies que la loi d'alors qualifiait\r
+_propos séditieux_. Depuis que le profil impérial avait disparu de la\r
+légion d'honneur, il ne s'habillait jamais _dans l'ordonnance_, comme il\r
+disait, afin de ne pas être forcé de porter sa croix. Il avait ôté\r
+lui-même dévotement l'effigie impériale de la croix que Napoléon lui\r
+avait donnée, cela faisait un trou, et il n'avait rien voulu mettre à la\r
+place. «Plutôt mourir, disait-il, que de porter sur mon coeur les trois\r
+crapauds!» Il raillait volontiers tout haut Louis XVIII. «Vieux goutteux\r
+à guêtres d'anglais!» disait-il, «qu'il s'en aille en Prusse avec son\r
+salsifis!» Heureux de réunir dans la même imprécation les deux choses\r
+qu'il détestait le plus, la Prusse et l'Angleterre. Il en fit tant qu'il\r
+perdit sa place. Le voilà sans pain sur le pavé avec femme et enfants.\r
+L'évêque le fit venir, le gronda doucement, et le nomma suisse de la\r
+cathédrale.\r
+\r
+M. Myriel était dans le diocèse le vrai pasteur, l'ami de tous. En neuf\r
+ans, à force de saintes actions et de douces manières, monseigneur\r
+Bienvenu avait rempli la ville de Digne d'une sorte de vénération tendre\r
+et filiale. Sa conduite même envers Napoléon avait été acceptée et comme\r
+tacitement pardonnée par le peuple, bon troupeau faible, qui adorait son\r
+empereur, mais qui aimait son évêque.\r
+\r
+\r
+\r
+\r
+Chapitre XII\r
+\r
+Solitude de monseigneur Bienvenu\r
+\r
+\r
+Il y a presque toujours autour d'un évêque une escouade de petits abbés\r
+comme autour d'un général une volée de jeunes officiers. C'est là ce que\r
+ce charmant saint François de Sales appelle quelque part «les prêtres\r
+blancs-becs». Toute carrière a ses aspirants qui font cortège aux\r
+arrivés. Pas une puissance qui n'ait son entourage; pas une fortune qui\r
+n'ait sa cour. Les chercheurs d'avenir tourbillonnent autour du présent\r
+splendide. Toute métropole a son état-major. Tout évêque un peu influent\r
+a près de lui sa patrouille de chérubins séminaristes, qui fait la ronde\r
+et maintient le bon ordre dans le palais épiscopal, et qui monte la\r
+garde autour du sourire de monseigneur. Agréer à un évêque, c'est le\r
+pied à l'étrier pour un sous-diacre. Il faut bien faire son chemin;\r
+l'apostolat ne dédaigne pas le canonicat.\r
+\r
+De même qu'il y a ailleurs les gros bonnets, il y a dans l'église les\r
+grosses mitres. Ce sont les évêques bien en cour, riches, rentés,\r
+habiles, acceptés du monde, sachant prier, sans doute, mais sachant\r
+aussi solliciter, peu scrupuleux de faire faire antichambre en leur\r
+personne à tout un diocèse, traits d'union entre la sacristie et la\r
+diplomatie, plutôt abbés que prêtres, plutôt prélats qu'évêques. Heureux\r
+qui les approche! Gens en crédit qu'ils sont, ils font pleuvoir autour\r
+d'eux, sur les empressés et les favorisés, et sur toute cette jeunesse\r
+qui sait plaire, les grasses paroisses, les prébendes, les\r
+archidiaconats, les aumôneries et les fonctions cathédrales, en\r
+attendant les dignités épiscopales. En avançant eux-mêmes, ils font\r
+progresser leurs satellites; c'est tout un système solaire en marche.\r
+Leur rayonnement empourpre leur suite. Leur prospérité s'émiette sur la\r
+cantonade en bonnes petites promotions. Plus grand diocèse au patron,\r
+plus grosse cure au favori. Et puis Rome est là. Un évêque qui sait\r
+devenir archevêque, un archevêque qui sait devenir cardinal, vous emmène\r
+comme conclaviste, vous entrez dans la rote, vous avez le pallium, vous\r
+voilà auditeur, vous voilà camérier, vous voilà monsignor, et de la\r
+Grandeur à Imminence il n'y a qu'un pas, et entre Imminence et la\r
+Sainteté il n'y a que la fumée d'un scrutin. Toute calotte peut rêver la\r
+tiare. Le prêtre est de nos jours le seul homme qui puisse régulièrement\r
+devenir roi; et quel roi! le roi suprême. Aussi quelle pépinière\r
+d'aspirations qu'un séminaire! Que d'enfants de choeur rougissants, que\r
+de jeunes abbés ont sur la tête le pot au lait de Perrette! Comme\r
+l'ambition s'intitule aisément vocation, qui sait? de bonne foi\r
+peut-être et se trompant elle-même, béate qu'elle est!\r
+\r
+Monseigneur Bienvenu, humble, pauvre, particulier, n'était pas compté\r
+parmi les grosses mitres. Cela était visible à l'absence complète de\r
+jeunes prêtres autour de lui. On a vu qu'à Paris «il n'avait pas pris».\r
+Pas un avenir ne songeait à se greffer sur ce vieillard solitaire. Pas\r
+une ambition en herbe ne faisait la folie de verdir à son ombre. Ses\r
+chanoines et ses grands vicaires étaient de bons vieux hommes, un peu\r
+peuple comme lui, murés comme lui dans ce diocèse sans issue sur le\r
+cardinafat, et qui ressemblaient à leur évêque, avec cette différence\r
+qu'eux étaient finis, et que lui était achevé.\r
+\r
+On sentait si bien l'impossibilité de croître près de monseigneur\r
+Bienvenu qu'à peine sortis du séminaire, les jeunes gens ordonnés par\r
+lui se faisaient recommander aux archevêques d'Aix ou d'Auch, et s'en\r
+allaient bien vite. Car enfin, nous le répétons, on veut être poussé. Un\r
+saint qui vit dans un excès d'abnégation est un voisinage dangereux; il\r
+pourrait bien vous communiquer par contagion une pauvreté incurable,\r
+l'ankylose des articulations utiles à l'avancement, et, en somme, plus\r
+de renoncement que vous n'en voulez; et l'on fuit cette vertu galeuse.\r
+De là l'isolement de monseigneur Bienvenu. Nous vivons dans une société\r
+sombre. Réussir, voilà l'enseignement qui tombe goutte à goutte de la\r
+corruption en surplomb.\r
+\r
+Soit dit en passant, c'est une chose assez hideuse que le succès. Sa\r
+fausse ressemblance avec le mérite trompe les hommes. Pour la foule, la\r
+réussite a presque le même profil que la suprématie. Le succès, ce\r
+ménechme du talent, a une dupe: l'histoire. Juvénal et Tacite seuls en\r
+bougonnent. De nos jours, une philosophie à peu près officielle est\r
+entrée en domesticité chez lui, porte la livrée du succès, et fait le\r
+service de son antichambre. Réussissez: théorie. Prospérité suppose\r
+Capacité. Gagnez à la loterie, vous voilà un habile homme. Qui triomphe\r
+est vénéré. Naissez coiffé, tout est là. Ayez de la chance, vous aurez\r
+le reste; soyez heureux, on vous croira grand. En dehors des cinq ou six\r
+exceptions immenses qui font l'éclat d'un siècle, l'admiration\r
+contemporaine n'est guère que myopie. Dorure est or. Être le premier\r
+venu, cela ne gâte rien, pourvu qu'on soit le parvenu. Le vulgaire est\r
+un vieux Narcisse qui s'adore lui-même et qui applaudit le vulgaire.\r
+Cette faculté énorme par laquelle on est Moïse, Eschyle, Dante,\r
+Michel-Ange ou Napoléon, la multitude la décerne d'emblée et par\r
+acclamation à quiconque atteint son but dans quoi que ce soit. Qu'un\r
+notaire se transfigure en député, qu'un faux Corneille fasse _Tiridate_,\r
+qu'un eunuque parvienne à posséder un harem, qu'un Prud'homme militaire\r
+gagne par accident la bataille décisive d'une époque, qu'un apothicaire\r
+invente les semelles de carton pour l'armée de Sambre-et-Meuse et se\r
+construise, avec ce carton vendu pour du cuir, quatre cent mille livres\r
+de rente, qu'un porte-balle épouse l'usure et la fasse accoucher de sept\r
+ou huit millions dont il est le père et dont elle est la mère, qu'un\r
+prédicateur devienne évêque par le nasillement, qu'un intendant de bonne\r
+maison soit si riche en sortant de service qu'on le fasse ministre des\r
+finances, les hommes appellent cela Génie, de même qu'ils appellent\r
+Beauté la figure de Mousqueton et Majesté l'encolure de Claude. Ils\r
+confondent avec les constellations de l'abîme les étoiles que font dans\r
+la vase molle du bourbier les pattes des canards.\r
+\r
+\r
+\r
+\r
+Chapitre XIII\r
+\r
+Ce qu'il croyait\r
+\r
+\r
+Au point de vue de l'orthodoxie, nous n'avons point à sonder M. l'évêque\r
+de Digne. Devant une telle âme, nous ne nous sentons en humeur que de\r
+respect. La conscience du juste doit être crue sur parole. D'ailleurs,\r
+de certaines natures étant données, nous admettons le développement\r
+possible de toutes les beautés de la vertu humaine dans une croyance\r
+différente de la nôtre.\r
+\r
+Que pensait-il de ce dogme-ci ou de ce mystère-là? Ces secrets du for\r
+intérieur ne sont connus que de la tombe où les âmes entrent nues. Ce\r
+dont nous sommes certain, c'est que jamais les difficultés de foi ne se\r
+résolvaient pour lui en hypocrisie. Aucune pourriture n'est possible au\r
+diamant. Il croyait le plus qu'il pouvait. _Credo in Patrem_,\r
+s'écriait-il souvent. Puisant d'ailleurs dans les bonnes oeuvres cette\r
+quantité de satisfaction qui suffit à la conscience, et qui vous dit\r
+tout bas: «Tu es avec Dieu.»\r
+\r
+Ce que nous croyons devoir noter, c'est que, en dehors, pour ainsi dire,\r
+et au-delà de sa foi, l'évêque avait un excès d'amour. C'est par là,\r
+_quia multum amavit_, qu'il était jugé vulnérable par les «hommes\r
+sérieux», les «personnes graves» et les «gens raisonnables»; locutions\r
+favorites de notre triste monde où l'égoïsme reçoit le mot d'ordre du\r
+pédantisme. Qu'était-ce que cet excès d'amour? C'était une bienveillance\r
+sereine, débordant les hommes, comme nous l'avons indiqué déjà, et, dans\r
+l'occasion, s'étendant jusqu'aux choses. Il vivait sans dédain. Il était\r
+indulgent pour la création de Dieu. Tout homme, même le meilleur, a en\r
+lui une dureté irréfléchie qu'il tient en réserve pour l'animal.\r
+L'évêque de Digne n'avait point cette dureté-là, particulière à beaucoup\r
+de prêtres pourtant. Il n'allait pas jusqu'au bramine, mais il semblait\r
+avoir médité cette parole de l'Ecclésiaste: «Sait-on où va l'âme des\r
+animaux?» Les laideurs de l'aspect, les difformités de l'instinct, ne le\r
+troublaient pas et ne l'indignaient pas. Il en était ému, presque\r
+attendri. Il semblait que, pensif, il en allât chercher, au-delà de la\r
+vie apparente, la cause, l'explication ou l'excuse. Il semblait par\r
+moments demander à Dieu des commutations. Il examinait sans colère, et\r
+avec l'oeil du linguiste qui déchiffre un palimpseste, la quantité de\r
+chaos qui est encore dans la nature. Cette rêverie faisait parfois\r
+sortir de lui des mots étranges. Un matin, il était dans son jardin; il\r
+se croyait seul, mais sa soeur marchait derrière lui sans qu'il la vît;\r
+tout à coup, il s'arrêta, et il regarda quelque chose à terre; c'était\r
+une grosse araignée, noire, velue, horrible. Sa soeur l'entendit qui\r
+disait:\r
+\r
+--Pauvre bête! ce n'est pas sa faute.\r
+\r
+Pourquoi ne pas dire ces enfantillages presque divins de la bonté?\r
+Puérilités, soit; mais ces puérilités sublimes ont été celles de saint\r
+François d'Assise et de Marc-Aurèle. Un jour il se donna une entorse\r
+pour n'avoir pas voulu écraser une fourmi.\r
+\r
+Ainsi vivait cet homme juste. Quelquefois, il s'endormait dans son\r
+jardin, et alors il n'était rien de plus vénérable.\r
+\r
+Monseigneur Bienvenu avait été jadis, à en croire les récits sur sa\r
+jeunesse et même sur sa virilité, un homme passionné, peut-être violent.\r
+Sa mansuétude universelle était moins un instinct de nature que le\r
+résultat d'une grande conviction filtrée dans son coeur à travers la vie\r
+et lentement tombée en lui, pensée à pensée; car, dans un caractère\r
+comme dans un rocher, il peut y avoir des trous de gouttes d'eau. Ces\r
+creusements-là sont ineffaçables; ces formations-là sont\r
+indestructibles.\r
+\r
+En 1815, nous croyons l'avoir dit, il atteignit soixante-quinze ans,\r
+mais il n'en paraissait pas avoir plus de soixante. Il n'était pas\r
+grand; il avait quelque embonpoint, et, pour le combattre, il faisait\r
+volontiers de longues marches à pied, il avait le pas ferme et n'était\r
+que fort peu courbé, détail d'où nous ne prétendons rien conclure;\r
+Grégoire XVI, à quatre-vingts ans, se tenait droit et souriant, ce qui\r
+ne l'empêchait pas d'être un mauvais évêque. Monseigneur Bienvenu avait\r
+ce que le peuple appelle «une belle tête», mais si aimable qu'on\r
+oubliait qu'elle était belle.\r
+\r
+Quand il causait avec cette santé enfantine qui était une de ses grâces,\r
+et dont nous avons déjà parlé, on se sentait à l'aise près de lui, il\r
+semblait que de toute sa personne il sortît de la joie. Son teint coloré\r
+et frais, toutes ses dents bien blanches qu'il avait conservées et que\r
+son rire faisait voir, lui donnaient cet air ouvert et facile qui fait\r
+dire d'un homme: «C'est un bon enfant», et d'un vieillard: «C'est un\r
+bonhomme». C'était, on s'en souvient, l'effet qu'il avait fait à\r
+Napoléon. Au premier abord, et pour qui le voyait pour la première fois,\r
+ce n'était guère qu'un bonhomme en effet. Mais si l'on restait quelques\r
+heures près de lui, et pour peu qu'on le vît pensif, le bonhomme se\r
+transfigurait peu à peu et prenait je ne sais quoi d'imposant; son front\r
+large et sérieux, auguste par les cheveux blancs, devenait auguste aussi\r
+par la méditation; la majesté se dégageait de cette bonté, sans que la\r
+bonté cessât de rayonner; on éprouvait quelque chose de l'émotion qu'on\r
+aurait si l'on voyait un ange souriant ouvrir lentement ses ailes sans\r
+cesser de sourire. Le respect, un respect inexprimable, vous pénétrait\r
+par degrés et vous montait au coeur, et l'on sentait qu'on avait devant\r
+soi une de ces âmes fortes, éprouvées et indulgentes, où la pensée est\r
+si grande qu'elle ne peut plus être que douce.\r
+\r
+Comme on l'a vu, la prière, la célébration des offices religieux,\r
+l'aumône, la consolation aux affligés, la culture d'un coin de terre, la\r
+fraternité, la frugalité, l'hospitalité, le renoncement, la confiance,\r
+l'étude, le travail remplissaient chacune des journées de sa vie.\r
+_Remplissaient_ est bien le mot, et certes cette journée de l'évêque\r
+était bien pleine jusqu'aux bords de bonnes pensées, de bonnes paroles\r
+et de bonnes actions. Cependant elle n'était pas complète si le temps\r
+froid ou pluvieux l'empêchait d'aller passer, le soir, quand les deux\r
+femmes s'étaient retirées, une heure ou deux dans son jardin avant de\r
+s'endormir. Il semblait que ce fût une sorte de rite pour lui de se\r
+préparer au sommeil par la méditation en présence des grands spectacles\r
+du ciel nocturne. Quelquefois, à une heure même assez avancée de la\r
+nuit, si les deux vieilles filles ne dormaient pas, elles l'entendaient\r
+marcher lentement dans les allées. Il était là, seul avec lui-même,\r
+recueilli, paisible, adorant, comparant la sérénité de son coeur à la\r
+sérénité de l'éther, ému dans les ténèbres par les splendeurs visibles\r
+des constellations et les splendeurs invisibles de Dieu, ouvrant son âme\r
+aux pensées qui tombent de l'inconnu. Dans ces moments-là, offrant son\r
+coeur à l'heure où les fleurs nocturnes offrent leur parfum, allumé\r
+comme une lampe au centre de la nuit étoilée, se répandant en extase au\r
+milieu du rayonnement universel de la création, il n'eût pu peut-être\r
+dire lui-même ce qui se passait dans son esprit, il sentait quelque\r
+chose s'envoler hors de lui et quelque chose descendre en lui.\r
+Mystérieux échanges des gouffres de l'âme avec les gouffres de\r
+l'univers!\r
+\r
+Il songeait à la grandeur et à la présence de Dieu; à l'éternité future,\r
+étrange mystère; à l'éternité passée, mystère plus étrange encore; à\r
+tous les infinis qui s'enfonçaient sous ses yeux dans tous les sens; et,\r
+sans chercher à comprendre l'incompréhensible, il le regardait. Il\r
+n'étudiait pas Dieu, il s'en éblouissait. Il considérait ces magnifiques\r
+rencontres des atomes qui donnent des aspects à la matière, révèlent les\r
+forces en les constatant, créent les individualités dans l'unité, les\r
+proportions dans l'étendue, l'innombrable dans l'infini, et par la\r
+lumière produisent la beauté. Ces rencontres se nouent et se dénouent\r
+sans cesse; de là la vie et la mort. Il s'asseyait sur un banc de bois\r
+adossé à une treille décrépite, et il regardait les astres à travers les\r
+silhouettes chétives et rachitiques de ses arbres fruitiers. Ce quart\r
+d'arpent, si pauvrement planté, si encombré de masures et de hangars,\r
+lui était cher et lui suffisait.\r
+\r
+Que fallait-il de plus à ce vieillard, qui partageait le loisir de sa\r
+vie, où il y avait si peu de loisir, entre le jardinage le jour et la\r
+contemplation la nuit? Cet étroit enclos, ayant les cieux pour plafond,\r
+n'était-ce pas assez pour pouvoir adorer Dieu tour à tour dans ses\r
+oeuvres les plus charmantes et dans ses oeuvres les plus sublimes?\r
+N'est-ce pas là tout, en effet, et que désirer au-delà? Un petit jardin\r
+pour se promener, et l'immensité pour rêver. À ses pieds ce qu'on peut\r
+cultiver et cueillir; sur sa tête ce qu'on peut étudier et méditer;\r
+quelques fleurs sur la terre et toutes les étoiles dans le ciel.\r

+\r
+Ce qu'il pensait\r
+\r
+\r
+Un dernier mot.\r
+\r
+Comme cette nature de détails pourrait, particulièrement au moment où\r
+nous sommes, et pour nous servir d'une expression actuellement à la\r
+mode, donner à l'évêque de Digne une certaine physionomie «panthéiste»,\r
+et faire croire, soit à son blâme, soit à sa louange, qu'il y avait en\r
+lui une de ces philosophies personnelles, propres à notre siècle, qui\r
+germent quelquefois dans les esprits solitaires et s'y construisent et y\r
+grandissent jusqu'à y remplacer les religions, nous insistons sur ceci\r
+que pas un de ceux qui ont connu monseigneur Bienvenu ne se fût cru\r
+autorisé à penser rien de pareil. Ce qui éclairait cet homme, c'était le\r
+coeur. Sa sagesse était faite de la lumière qui vient de là.\r
+\r
+Point de systèmes, beaucoup d'oeuvres. Les spéculations abstruses\r
+contiennent du vertige; rien n'indique qu'il hasardât son esprit dans\r
+les apocalypses. L'apôtre peut être hardi, mais l'évêque doit être\r
+timide. Il se fût probablement fait scrupule de sonder trop avant de\r
+certains problèmes réservés en quelque sorte aux grands esprits\r
+terribles. Il y a de l'horreur sacrée sous les porches de l'énigme; ces\r
+ouvertures sombres sont là béantes, mais quelque chose vous dit, à vous\r
+passant de la vie, qu'on n'entre pas. Malheur à qui y pénètre! Les\r
+génies, dans les profondeurs inouïes de l'abstraction et de la\r
+spéculation pure, situés pour ainsi dire au-dessus des dogmes, proposent\r
+leurs idées à Dieu. Leur prière offre audacieusement la discussion. Leur\r
+adoration interroge. Ceci est la religion directe, pleine d'anxiété et\r
+de responsabilité pour qui en tente les escarpements.\r
+\r
+La méditation humaine n'a point de limite. À ses risques et périls, elle\r
+analyse et creuse son propre éblouissement. On pourrait presque dire\r
+que, par une sorte de réaction splendide, elle en éblouit la nature; le\r
+mystérieux monde qui nous entoure rend ce qu'il reçoit, il est probable\r
+que les contemplateurs sont contemplés. Quoi qu'il en soit, il y a sur\r
+la terre des hommes--sont-ce des hommes?--qui aperçoivent distinctement\r
+au fond des horizons du rêve les hauteurs de l'absolu, et qui ont la\r
+vision terrible de la montagne infinie. Monseigneur Bienvenu n'était\r
+point de ces hommes-là, monseigneur Bienvenu n'était pas un génie. Il\r
+eût redouté ces sublimités d'où quelques-uns, très grands même, comme\r
+Swedenborg et Pascal, ont glissé dans la démence. Certes, ces puissantes\r
+rêveries ont leur utilité morale, et par ces routes ardues on s'approche\r
+de la perfection idéale. Lui, il prenait le sentier qui abrège:\r
+l'évangile. Il n'essayait point de faire faire à sa chasuble les plis du\r
+manteau d'Élie, il ne projetait aucun rayon d'avenir sur le roulis\r
+ténébreux des événements, il ne cherchait pas à condenser en flamme la\r
+lueur des choses, il n'avait rien du prophète et rien du mage. Cette âme\r
+simple aimait, voilà tout.\r
+\r
+Qu'il dilatât la prière jusqu'à une aspiration surhumaine, cela est\r
+probable; mais on ne peut pas plus prier trop qu'aimer trop; et, si\r
+c'était une hérésie de prier au-delà des textes, sainte Thérèse et saint\r
+Jérôme seraient des hérétiques.\r
+\r
+Il se penchait sur ce qui gémit et sur ce qui expie. L'univers lui\r
+apparaissait comme une immense maladie; il sentait partout de la fièvre,\r
+il auscultait partout de la souffrance, et, sans chercher à deviner\r
+l'énigme, il tâchait de panser la plaie. Le redoutable spectacle des\r
+choses créées développait en lui l'attendrissement; il n'était occupé\r
+qu'à trouver pour lui-même et à inspirer aux autres la meilleure manière\r
+de plaindre et de soulager. Ce qui existe était pour ce bon et rare\r
+prêtre un sujet permanent de tristesse cherchant à consoler.\r
+\r
+Il y a des hommes qui travaillent à l'extraction de l'or; lui, il\r
+travaillait à l'extraction de la pitié. L'universelle misère était sa\r
+mine. La douleur partout n'était qu'une occasion de bonté toujours.\r
+_Aimez-vous les uns les autres;_ il déclarait cela complet, ne\r
+souhaitait rien de plus, et c'était là toute sa doctrine. Un jour, cet\r
+homme qui se croyait «philosophe», ce sénateur, déjà nommé, dit à\r
+l'évêque:\r
+\r
+--Mais voyez donc le spectacle du monde; guerre de tous contre tous; le\r
+plus fort a le plus d'esprit. Votre _aimez-vous les uns les autres_ est\r
+une bêtise.\r
+\r
+--Eh bien, répondit monseigneur Bienvenu sans disputer, si c'est une\r
+bêtise, l'âme doit s'y enfermer comme la perle dans l'huître.\r
+\r
+Il s'y enfermait donc, il y vivait, il s'en satisfaisait absolument,\r
+laissant de côté les questions prodigieuses qui attirent et qui\r
+épouvantent, les perspectives insondables de l'abstraction, les\r
+précipices de la métaphysique, toutes ces profondeurs convergentes, pour\r
+l'apôtre à Dieu, pour l'athée au néant: la destinée, le bien et le mal,\r
+la guerre de l'être contre l'être, la conscience de l'homme, le\r
+somnambulisme pensif de l'animal, la transformation par la mort, la\r
+récapitulation d'existences que contient le tombeau, la greffe\r
+incompréhensible des amours successifs sur le moi persistant, l'essence,\r
+la substance, le Nil et l'Ens, l'âme, la nature, la liberté, la\r
+nécessité; problèmes à pic, épaisseurs sinistres, où se penchent les\r
+gigantesques archanges de l'esprit humain; formidables abîmes que\r
+Lucrèce, Manou, saint Paul et Dante contemplent avec cet oeil fulgurant\r
+qui semble, en regardant fixement l'infini, y faire éclore des étoiles.\r
+\r
+Monseigneur Bienvenu était simplement un homme qui constatait du dehors\r
+les questions mystérieuses sans les scruter, sans les agiter, et sans en\r
+troubler son propre esprit, et qui avait dans l'âme le grave respect de\r
+l'ombre.\r

+Chapitre I\r
+\r
+Le soir d'un jour de marche\r
+\r
+\r
+Dans les premiers jours du mois d'octobre 1815, une heure environ avant\r
+le coucher du soleil, un homme qui voyageait à pied entrait dans la\r
+petite ville de Digne. Les rares habitants qui se trouvaient en ce moment\r
+à leurs fenêtres ou sur le seuil de leurs maisons regardaient ce\r
+voyageur avec une sorte d'inquiétude. Il était difficile de rencontrer\r
+un passant d'un aspect plus misérable. C'était un homme de moyenne\r
+taille, trapu et robuste, dans la force de l'âge. Il pouvait avoir\r
+quarante-six ou quarante-huit ans. Une casquette à visière de cuir\r
+rabattue cachait en partie son visage, brûlé par le soleil et le hâle,\r
+et ruisselant de sueur. Sa chemise de grosse toile jaune, rattachée au\r
+col par une petite ancre d'argent, laissait voir sa poitrine velue; il\r
+avait une cravate tordue en corde, un pantalon de coutil bleu, usé et\r
+râpé, blanc à un genou, troué à l'autre, une vieille blouse grise en\r
+haillons, rapiécée à l'un des coudes d'un morceau de drap vert cousu\r
+avec de la ficelle, sur le dos un sac de soldat fort plein, bien bouclé\r
+et tout neuf, à la main un énorme bâton noueux, les pieds sans bas dans\r
+des souliers ferrés, la tête tondue et la barbe longue.\r
+\r
+La sueur, la chaleur, le voyage à pied, la poussière, ajoutaient je ne\r
+sais quoi de sordide à cet ensemble délabré.\r
+\r
+Les cheveux étaient ras, et pourtant hérissés; car ils commençaient à\r
+pousser un peu, et semblaient n'avoir pas été coupés depuis quelque\r
+temps.\r
+\r
+Personne ne le connaissait. Ce n'était évidemment qu'un passant. D'où\r
+venait-il? Du midi. Des bords de la mer peut-être. Car il faisait son\r
+entrée dans Digne par la même rue qui, sept mois auparavant, avait vu\r
+passer l'empereur Napoléon allant de Cannes à Paris. Cet homme avait dû\r
+marcher tout le jour. Il paraissait très fatigué. Des femmes de l'ancien\r
+bourg qui est au bas de la ville l'avaient vu s'arrêter sous les arbres\r
+du boulevard Gassendi et boire à la fontaine qui est à l'extrémité de la\r
+promenade. Il fallait qu'il eût bien soif, car des enfants qui le\r
+suivaient le virent encore s'arrêter, et boire, deux cents pas plus\r
+loin, à la fontaine de la place du marché.\r
+\r
+Arrivé au coin de la rue Poichevert, il tourna à gauche et se dirigea\r
+vers la mairie. Il y entra, puis sortit un quart d'heure après. Un\r
+gendarme était assis près de la porte sur le banc de pierre où le\r
+général Drouot monta le 4 mars pour lire à la foule effarée des\r
+habitants de Digne la proclamation du golfe Juan. L'homme ôta sa\r
+casquette et salua humblement le gendarme.\r
+\r
+Le gendarme, sans répondre à son salut, le regarda avec attention, le\r
+suivit quelque temps des yeux, puis entra dans la maison de ville.\r
+\r
+Il y avait alors à Digne une belle auberge à l'enseigne de _la\r
+Croix-de-Colbas_. Cette auberge avait pour hôtelier un nommé Jacquin\r
+Labarre, homme considéré dans la ville pour sa parenté avec un autre\r
+Labarre, qui tenait à Grenoble l'auberge des _Trois-Dauphins_ et qui\r
+avait servi dans les guides. Lors du débarquement de l'empereur,\r
+beaucoup de bruits avaient couru dans le pays sur cette auberge des\r
+_Trois-Dauphins_. On contait que le général Bertrand, déguisé en\r
+charretier, y avait fait de fréquents voyages au mois de janvier, et\r
+qu'il y avait distribué des croix d'honneur à des soldats et des\r
+poignées de napoléons à des bourgeois. La réalité est que l'empereur,\r
+entré dans Grenoble, avait refusé de s'installer à l'hôtel de la\r
+préfecture; il avait remercié le maire en disant: _Je vais chez un brave\r
+homme que je connais_, et il était allé aux _Trois-Dauphins_. Cette\r
+gloire du Labarre des _Trois-Dauphins_ se reflétait à vingt-cinq lieues\r
+de distance jusque sur le Labarre de la _Croix-de-Colbas_. On disait de\r
+lui dans la ville: _C'est le cousin de celui de Grenoble_.\r
+\r
+L'homme se dirigea vers cette auberge, qui était la meilleure du pays.\r
+Il entra dans la cuisine, laquelle s'ouvrait de plain-pied sur la rue.\r
+Tous les fourneaux étaient allumés; un grand feu flambait gaîment dans\r
+la cheminée. L'hôte, qui était en même temps le chef, allait de l'âtre\r
+aux casseroles, fort occupé et surveillant un excellent dîner destiné à\r
+des rouliers qu'on entendait rire et parler à grand bruit dans une salle\r
+voisine. Quiconque a voyagé sait que personne ne fait meilleure chère\r
+que les rouliers. Une marmotte grasse, flanquée de perdrix blanches et\r
+de coqs de bruyère, tournait sur une longue broche devant le feu; sur\r
+les fourneaux cuisaient deux grosses carpes du lac de Lauzet et une\r
+truite du lac d'Alloz.\r
+\r
+L'hôte, entendant la porte s'ouvrir et entrer un nouveau venu, dit sans\r
+lever les yeux de ses fourneaux:\r
+\r
+--Que veut monsieur?\r
+\r
+--Manger et coucher, dit l'homme.\r
+\r
+--Rien de plus facile, reprit l'hôte.\r
+\r
+En ce moment il tourna la tête, embrassa d'un coup d'oeil tout\r
+l'ensemble du voyageur, et ajouta:\r
+\r
+--... en payant.\r
+\r
+L'homme tira une grosse bourse de cuir de la poche de sa blouse et\r
+répondit:\r
+\r
+--J'ai de l'argent.\r
+\r
+--En ce cas on est à vous, dit l'hôte.\r
+\r
+L'homme remit sa bourse en poche, se déchargea de son sac, le posa à\r
+terre près de la porte, garda son bâton à la main, et alla s'asseoir sur\r
+une escabelle basse près du feu. Digne est dans la montagne. Les soirées\r
+d'octobre y sont froides.\r
+\r
+Cependant, tout en allant et venant, l'homme considérait le voyageur.\r
+\r
+--Dîne-t-on bientôt? dit l'homme.\r
+\r
+--Tout à l'heure, dit l'hôte.\r
+\r
+Pendant que le nouveau venu se chauffait, le dos tourné, le digne\r
+aubergiste Jacquin Labarre tira un crayon de sa poche, puis il déchira\r
+le coin d'un vieux journal qui traînait sur une petite table près de la\r
+fenêtre. Sur la marge blanche il écrivit une ligne ou deux, plia sans\r
+cacheter et remit ce chiffon de papier à un enfant qui paraissait lui\r
+servir tout à la fois de marmiton et de laquais. L'aubergiste dit un mot\r
+à l'oreille du marmiton, et l'enfant partit en courant dans la direction\r
+de la mairie.\r
+\r
+Le voyageur n'avait rien vu de tout cela.\r
+\r
+Il demanda encore une fois:\r
+\r
+--Dîne-t-on bientôt?\r
+\r
+--Tout à l'heure, dit l'hôte.\r
+\r
+L'enfant revint. Il rapportait le papier. L'hôte le déplia avec\r
+empressement, comme quelqu'un qui attend une réponse. Il parut lire\r
+attentivement, puis hocha la tête, et resta un moment pensif. Enfin il\r
+fit un pas vers le voyageur qui semblait plongé dans des réflexions peu\r
+sereines.\r
+\r
+--Monsieur, dit-il, je ne puis vous recevoir.\r
+\r
+L'homme se dressa à demi sur son séant.\r
+\r
+--Comment! Avez-vous peur que je ne paye pas? Voulez-vous que je paye\r
+d'avance? J'ai de l'argent, vous dis-je.\r
+\r
+--Ce n'est pas cela.\r
+\r
+--Quoi donc?\r
+\r
+--Vous avez de l'argent....\r
+\r
+--Oui, dit l'homme.\r
+\r
+--Et moi, dit l'hôte, je n'ai pas de chambre.\r
+\r
+L'homme reprit tranquillement:\r
+\r
+--Mettez-moi à l'écurie.\r
+\r
+--Je ne puis.\r
+\r
+--Pourquoi?\r
+\r
+--Les chevaux prennent toute la place.\r
+\r
+--Eh bien, repartit l'homme, un coin dans le grenier. Une botte de\r
+paille. Nous verrons cela après dîner.\r
+\r
+--Je ne puis vous donner à dîner.\r
+\r
+Cette déclaration, faite d'un ton mesuré, mais ferme, parut grave à\r
+l'étranger. Il se leva.\r
+\r
+--Ah bah! mais je meurs de faim, moi. J'ai marché dès le soleil levé.\r
+J'ai fait douze lieues. Je paye. Je veux manger.\r
+\r
+--Je n'ai rien, dit l'hôte.\r
+\r
+L'homme éclata de rire et se tourna vers la cheminée et les fourneaux.\r
+\r
+--Rien! et tout cela?\r
+\r
+--Tout cela m'est retenu.\r
+\r
+--Par qui?\r
+\r
+--Par ces messieurs les rouliers.\r
+\r
+--Combien sont-ils?\r
+\r
+--Douze.\r
+\r
+--Il y a là à manger pour vingt.\r
+\r
+--Ils ont tout retenu et tout payé d'avance.\r
+\r
+L'homme se rassit et dit sans hausser la voix:\r
+\r
+--Je suis à l'auberge, j'ai faim, et je reste.\r
+\r
+L'hôte alors se pencha à son oreille, et lui dit d'un accent qui le fit\r
+tressaillir:\r
+\r
+--Allez-vous en.\r
+\r
+Le voyageur était courbé en cet instant et poussait quelques braises\r
+dans le feu avec le bout ferré de son bâton, il se retourna vivement,\r
+et, comme il ouvrait la bouche pour répliquer, l'hôte le regarda\r
+fixement et ajouta toujours à voix basse:\r
+\r
+--Tenez, assez de paroles comme cela. Voulez-vous que je vous dise votre\r
+nom? Vous vous appelez Jean Valjean. Maintenant voulez-vous que je vous\r
+dise qui vous êtes? En vous voyant entrer, je me suis douté de quelque\r
+chose, j'ai envoyé à la mairie, et voici ce qu'on m'a répondu.\r
+Savez-vous lire?\r
+\r
+En parlant ainsi il tendait à l'étranger, tout déplié, le papier qui\r
+venait de voyager de l'auberge à la mairie, et de la mairie à l'auberge.\r
+L'homme y jeta un regard. L'aubergiste reprit après un silence:\r
+\r
+--J'ai l'habitude d'être poli avec tout le monde. Allez-vous-en.\r
+\r
+L'homme baissa la tête, ramassa le sac qu'il avait déposé à terre, et\r
+s'en alla. Il prit la grande rue. Il marchait devant lui au hasard,\r
+rasant de près les maisons, comme un homme humilié et triste. Il ne se\r
+retourna pas une seule fois. S'il s'était retourné, il aurait vu\r
+l'aubergiste de la _Croix-de-Colbas_ sur le seuil de sa porte, entouré\r
+de tous les voyageurs de son auberge et de tous les passants de la rue,\r
+parlant vivement et le désignant du doigt, et, aux regards de défiance\r
+et d'effroi du groupe, il aurait deviné qu'avant peu son arrivée serait\r
+l'événement de toute la ville.\r
+\r
+Il ne vit rien de tout cela. Les gens accablés ne regardent pas derrière\r
+eux. Ils ne savent que trop que le mauvais sort les suit.\r
+\r
+Il chemina ainsi quelque temps, marchant toujours, allant à l'aventure\r
+par des rues qu'il ne connaissait pas, oubliant la fatigue, comme cela\r
+arrive dans la tristesse. Tout à coup il sentit vivement la faim. La\r
+nuit approchait. Il regarda autour de lui pour voir s'il ne découvrirait\r
+pas quelque gîte.\r
+\r
+La belle hôtellerie s'était fermée pour lui; il cherchait quelque\r
+cabaret bien humble, quelque bouge bien pauvre.\r
+\r
+Précisément une lumière s'allumait au bout de la rue; une branche de\r
+pin, pendue à une potence en fer, se dessinait sur le ciel blanc du\r
+crépuscule. Il y alla.\r
+\r
+C'était en effet un cabaret. Le cabaret qui est dans la rue de Chaffaut.\r
+\r
+Le voyageur s'arrêta un moment, et regarda par la vitre l'intérieur de\r
+la salle basse du cabaret, éclairée par une petite lampe sur une table\r
+et par un grand feu dans la cheminée. Quelques hommes y buvaient. L'hôte\r
+se chauffait. La flamme faisait bruire une marmite de fer accrochée à la\r
+crémaillère.\r
+\r
+On entre dans ce cabaret, qui est aussi une espèce d'auberge, par deux\r
+portes. L'une donne sur la rue, l'autre s'ouvre sur une petite cour\r
+pleine de fumier.\r
+\r
+Le voyageur n'osa pas entrer par la porte de la rue. Il se glissa dans\r
+la cour, s'arrêta encore, puis leva timidement le loquet et poussa la\r
+porte.\r
+\r
+--Qui va là? dit le maître.\r
+\r
+--Quelqu'un qui voudrait souper et coucher.\r
+\r
+--C'est bon. Ici on soupe et on couche.\r
+\r
+Il entra. Tous les gens qui buvaient se retournèrent. La lampe\r
+l'éclairait d'un côté, le feu de l'autre. On l'examina quelque temps\r
+pendant qu'il défaisait son sac.\r
+\r
+L'hôte lui dit:\r
+\r
+--Voilà du feu. Le souper cuit dans la marmite. Venez vous chauffer,\r
+camarade.\r
+\r
+Il alla s'asseoir près de l'âtre. Il allongea devant le feu ses pieds\r
+meurtris par la fatigue; une bonne odeur sortait de la marmite. Tout ce\r
+qu'on pouvait distinguer de son visage sous sa casquette baissée prit\r
+une vague apparence de bien-être mêlée à cet autre aspect si poignant\r
+que donne l'habitude de la souffrance.\r
+\r
+C'était d'ailleurs un profil ferme, énergique et triste. Cette\r
+physionomie était étrangement composée; elle commençait par paraître\r
+humble et finissait par sembler sévère. L'oeil luisait sous les sourcils\r
+comme un feu sous une broussaille.\r
+\r
+Cependant un des hommes attablés était un poissonnier qui, avant\r
+d'entrer au cabaret de la rue de Chaffaut, était allé mettre son cheval\r
+à l'écurie chez Labarre. Le hasard faisait que le matin même il avait\r
+rencontré cet étranger de mauvaise mine, cheminant entre Bras dasse\r
+et... j'ai oublié le nom. (Je crois que c'est Escoublon). Or, en le\r
+rencontrant, l'homme, qui paraissait déjà très fatigué, lui avait\r
+demandé de le prendre en croupe; à quoi le poissonnier n'avait répondu\r
+qu'en doublant le pas. Ce poissonnier faisait partie, une demi-heure\r
+auparavant, du groupe qui entourait Jacquin Labarre, et lui-même avait\r
+raconté sa désagréable rencontre du matin aux gens de _la\r
+Croix-de-Colbas_. Il fit de sa place au cabaretier un signe\r
+imperceptible. Le cabaretier vint à lui. Ils échangèrent quelques\r
+paroles à voix basse. L'homme était retombé dans ses réflexions.\r
+\r
+Le cabaretier revint à la cheminée, posa brusquement sa main sur\r
+l'épaule de l'homme, et lui dit:\r
+\r
+--Tu vas t'en aller d'ici.\r
+\r
+L'étranger se retourna et répondit avec douceur.\r
+\r
+--Ah! vous savez?\r
+\r
+--Oui.\r
+\r
+--On m'a renvoyé de l'autre auberge.\r
+\r
+--Et l'on te chasse de celle-ci.\r
+\r
+--Où voulez-vous que j'aille?\r
+\r
+--Ailleurs.\r
+\r
+L'homme prit son bâton et son sac, et s'en alla.\r
+\r
+Comme il sortait, quelques enfants, qui l'avaient suivi depuis _la\r
+Croix-de-Colbas_ et qui semblaient l'attendre, lui jetèrent des pierres.\r
+Il revint sur ses pas avec colère et les menaça de son bâton; les\r
+enfants se dispersèrent comme une volée d'oiseaux.\r
+\r
+Il passa devant la prison. À la porte pendait une chaîne de fer attachée\r
+à une cloche. Il sonna.\r
+\r
+Un guichet s'ouvrit.\r
+\r
+--Monsieur le guichetier, dit-il en ôtant respectueusement sa casquette,\r
+voudriez-vous bien m'ouvrir et me loger pour cette nuit?\r
+\r
+Une voix répondit:\r
+\r
+--Une prison n'est pas une auberge. Faites-vous arrêter. On vous\r
+ouvrira.\r
+\r
+Le guichet se referma.\r
+\r
+Il entra dans une petite rue où il y a beaucoup de jardins. Quelques-uns\r
+ne sont enclos que de haies, ce qui égaye la rue. Parmi ces jardins et\r
+ces haies, il vit une petite maison d'un seul étage dont la fenêtre\r
+était éclairée. Il regarda par cette vitre comme il avait fait pour le\r
+cabaret. C'était une grande chambre blanchie à la chaux, avec un lit\r
+drapé d'indienne imprimée, et un berceau dans un coin, quelques chaises\r
+de bois et un fusil à deux coups accroché au mur. Une table était servie\r
+au milieu de la chambre. Une lampe de cuivre éclairait la nappe de\r
+grosse toile blanche, le broc d'étain luisant comme l'argent et plein de\r
+vin et la soupière brune qui fumait. À cette table était assis un homme\r
+d'une quarantaine d'années, à la figure joyeuse et ouverte, qui faisait\r
+sauter un petit enfant sur ses genoux. Près de lui, une femme toute\r
+jeune allaitait un autre enfant. Le père riait, l'enfant riait, la mère\r
+souriait.\r
+\r
+L'étranger resta un moment rêveur devant ce spectacle doux et calmant.\r
+Que se passait-il en lui? Lui seul eût pu le dire. Il est probable qu'il\r
+pensa que cette maison joyeuse serait hospitalière, et que là où il\r
+voyait tant de bonheur il trouverait peut-être un peu de pitié.\r
+\r
+Il frappa au carreau un petit coup très faible.\r
+\r
+On n'entendit pas.\r
+\r
+Il frappa un second coup.\r
+\r
+Il entendit la femme qui disait:\r
+\r
+--Mon homme, il me semble qu'on frappe.\r
+\r
+--Non, répondit le mari.\r
+\r
+Il frappa un troisième coup.\r
+\r
+Le mari se leva, prit la lampe, et alla à la porte qu'il ouvrit.\r
+\r
+C'était un homme de haute taille, demi-paysan, demi-artisan. Il portait\r
+un vaste tablier de cuir qui montait jusqu'à son épaule gauche, et dans\r
+lequel faisaient ventre un marteau, un mouchoir rouge, une poire à\r
+poudre, toutes sortes d'objets que la ceinture retenait comme dans une\r
+poche. Il renversait la tête en arrière; sa chemise largement ouverte et\r
+rabattue montrait son cou de taureau, blanc et nu. Il avait d'épais\r
+sourcils, d'énormes favoris noirs, les yeux à fleur de tête, le bas du\r
+visage en museau, et sur tout cela cet air d'être chez soi qui est une\r
+chose inexprimable.\r
+\r
+--Monsieur, dit le voyageur, pardon. En payant, pourriez-vous me donner\r
+une assiettée de soupe et un coin pour dormir dans ce hangar qui est là\r
+dans ce jardin? Dites, pourriez-vous? En payant?\r
+\r
+--Qui êtes-vous? demanda le maître du logis.\r
+\r
+L'homme répondit:\r
+\r
+--J'arrive de Puy-Moisson. J'ai marché toute la journée. J'ai fait douze\r
+lieues. Pourriez-vous? En payant?\r
+\r
+--Je ne refuserais pas, dit le paysan, de loger quelqu'un de bien qui\r
+payerait. Mais pourquoi n'allez-vous pas à l'auberge.\r
+\r
+--Il n'y a pas de place.\r
+\r
+--Bah! pas possible. Ce n'est pas jour de foire ni de marché. Êtes-vous\r
+allé chez Labarre?\r
+\r
+--Oui.\r
+\r
+--Eh bien?\r
+\r
+Le voyageur répondit avec embarras:\r
+\r
+--Je ne sais pas, il ne m'a pas reçu.\r
+\r
+--Êtes-vous allé chez chose, de la rue de Chaffaut?\r
+\r
+L'embarras de l'étranger croissait. Il balbutia:\r
+\r
+--Il ne m'a pas reçu non plus.\r
+\r
+Le visage du paysan prit une expression de défiance, il regarda le\r
+nouveau venu de la tête aux pieds, et tout à coup il s'écria avec une\r
+sorte de frémissement:\r
+\r
+--Est-ce que vous seriez l'homme?...\r
+\r
+Il jeta un nouveau coup d'oeil sur l'étranger, fit trois pas en arrière,\r
+posa la lampe sur la table et décrocha son fusil du mur.\r
+\r
+Cependant aux paroles du paysan: _Est-ce que vous seriez l'homme?..._ la\r
+femme s'était levée, avait pris ses deux enfants dans ses bras et\r
+s'était réfugiée précipitamment derrière son mari, regardant l'étranger\r
+avec épouvante, la gorge nue, les yeux effarés, en murmurant tout bas:_\r
+Tso-maraude_.\r
+\r
+Tout cela se fit en moins de temps qu'il ne faut pour se le figurer.\r
+Après avoir examiné quelques instants l'homme comme on examine une\r
+vipère, le maître du logis revint à la porte et dit:\r
+\r
+--Va-t'en.\r
+\r
+--Par grâce, reprit l'homme, un verre d'eau.\r
+\r
+--Un coup de fusil! dit le paysan.\r
+\r
+Puis il referma la porte violemment, et l'homme l'entendit tirer deux\r
+gros verrous. Un moment après, la fenêtre se ferma au volet, et un bruit\r
+de barre de fer qu'on posait parvint au dehors.\r
+\r
+La nuit continuait de tomber. Le vent froid des Alpes soufflait. À la\r
+lueur du jour expirant, l'étranger aperçut dans un des jardins qui\r
+bordent la rue une sorte de hutte qui lui parut maçonnée en mottes de\r
+gazon. Il franchit résolument une barrière de bois et se trouva dans le\r
+jardin. Il s'approcha de la hutte; elle avait pour porte une étroite\r
+ouverture très basse et elle ressemblait à ces constructions que les\r
+cantonniers se bâtissent au bord des routes. Il pensa sans doute que\r
+c'était en effet le logis d'un cantonnier; il souffrait du froid et de\r
+la faim; il s'était résigné à la faim, mais c'était du moins là un abri\r
+contre le froid. Ces sortes de logis ne sont habituellement pas occupés\r
+la nuit. Il se coucha à plat ventre et se glissa dans la hutte. Il y\r
+faisait chaud, et il y trouva un assez bon lit de paille. Il resta un\r
+moment étendu sur ce lit, sans pouvoir faire un mouvement tant il était\r
+fatigué. Puis, comme son sac sur son dos le gênait et que c'était\r
+d'ailleurs un oreiller tout trouvé, il se mit à déboucler une des\r
+courroies. En ce moment un grondement farouche se fit entendre. Il leva\r
+les yeux. La tête d'un dogue énorme se dessinait dans l'ombre à\r
+l'ouverture de la hutte.\r
+\r
+C'était la niche d'un chien.\r
+\r
+Il était lui-même vigoureux et redoutable; il s'arma de son bâton, il se\r
+fit de son sac un bouclier, et sortit de la niche comme il put, non sans\r
+élargir les déchirures de ses haillons.\r
+\r
+Il sortit également du jardin, mais à reculons, obligé, pour tenir le\r
+dogue en respect, d'avoir recours à cette manoeuvre du bâton que les\r
+maîtres en ce genre d'escrime appellent _la rose couverte_.\r
+\r
+Quand il eut, non sans peine, repassé la barrière et qu'il se retrouva\r
+dans la rue, seul, sans gîte, sans toit, sans abri, chassé même de ce\r
+lit de paille et de cette niche misérable, il se laissa tomber plutôt\r
+qu'il ne s'assit sur une pierre, et il paraît qu'un passant qui\r
+traversait l'entendit s'écrier:\r
+\r
+--Je ne suis pas même un chien!\r
+\r
+Bientôt il se releva et se remit à marcher. Il sortit de la ville,\r
+espérant trouver quelque arbre ou quelque meule dans les champs, et s'y\r
+abriter.\r
+\r
+Il chemina ainsi quelque temps, la tête toujours baissée. Quand il se\r
+sentit loin de toute habitation humaine, il leva les yeux et chercha\r
+autour de lui. Il était dans un champ; il avait devant lui une de ces\r
+collines basses couvertes de chaume coupé ras, qui après la moisson\r
+ressemblent à des têtes tondues.\r
+\r
+L'horizon était tout noir; ce n'était pas seulement le sombre de la\r
+nuit; c'étaient des nuages très bas qui semblaient s'appuyer sur la\r
+colline même et qui montaient, emplissant tout le ciel. Cependant, comme\r
+la lune allait se lever et qu'il flottait encore au zénith un reste de\r
+clarté crépusculaire, ces nuages formaient au haut du ciel une sorte de\r
+voûte blanchâtre d'où tombait sur la terre une lueur.\r
+\r
+La terre était donc plus éclairée que le ciel, ce qui est un effet\r
+particulièrement sinistre, et la colline, d'un pauvre et chétif contour,\r
+se dessinait vague et blafarde sur l'horizon ténébreux. Tout cet\r
+ensemble était hideux, petit, lugubre et borné. Rien dans le champ ni\r
+sur la colline qu'un arbre difforme qui se tordait en frissonnant à\r
+quelques pas du voyageur.\r
+\r
+Cet homme était évidemment très loin d'avoir de ces délicates habitudes\r
+d'intelligence et d'esprit qui font qu'on est sensible aux aspects\r
+mystérieux des choses; cependant il y avait dans ce ciel, dans cette\r
+colline, dans cette plaine et dans cet arbre, quelque chose de si\r
+profondément désolé qu'après un moment d'immobilité et de rêverie, il\r
+rebroussa chemin brusquement. Il y a des instants où la nature semble\r
+hostile.\r
+\r
+Il revint sur ses pas. Les portes de Digne étaient fermées. Digne, qui a\r
+soutenu des sièges dans les guerres de religion, était encore entourée\r
+en 1815 de vieilles murailles flanquées de tours carrées qu'on a\r
+démolies depuis. Il passa par une brèche et rentra dans la ville.\r
+\r
+Il pouvait être huit heures du soir. Comme il ne connaissait pas les\r
+rues, il recommença sa promenade à l'aventure.\r
+\r
+Il parvint ainsi à la préfecture, puis au séminaire. En passant sur la\r
+place de la cathédrale, il montra le poing à l'église.\r
+\r
+Il y a au coin de cette place une imprimerie. C'est là que furent\r
+imprimées pour la première fois les proclamations de l'empereur et de la\r
+garde impériale à l'armée, apportées de l'île d'Elbe et dictées par\r
+Napoléon lui-même.\r
+\r
+Épuisé de fatigue et n'espérant plus rien, il se coucha sur le banc de\r
+pierre qui est à la porte de cette imprimerie.\r
+\r
+Une vieille femme sortait de l'église en ce moment. Elle vit cet homme\r
+étendu dans l'ombre.\r
+\r
+--Que faites-vous là, mon ami? dit-elle.\r
+\r
+Il répondit durement et avec colère:\r
+\r
+--Vous le voyez, bonne femme, je me couche.\r
+\r
+La bonne femme, bien digne de ce nom en effet, était madame la marquise\r
+de R.\r
+\r
+--Sur ce banc? reprit-elle.\r
+\r
+--J'ai eu pendant dix-neuf ans un matelas de bois, dit l'homme, j'ai\r
+aujourd'hui un matelas de pierre.\r
+\r
+--Vous avez été soldat?\r
+\r
+--Oui, bonne femme. Soldat.\r
+\r
+--Pourquoi n'allez-vous pas à l'auberge?\r
+\r
+--Parce que je n'ai pas d'argent.\r
+\r
+--Hélas, dit madame de R., je n'ai dans ma bourse que quatre sous.\r
+\r
+--Donnez toujours.\r
+\r
+L'homme prit les quatre sous. Madame de R. continua:\r
+\r
+--Vous ne pouvez vous loger avec si peu dans une auberge. Avez-vous\r
+essayé pourtant? Il est impossible que vous passiez ainsi la nuit. Vous\r
+avez sans doute froid et faim. On aurait pu vous loger par charité.\r
+\r
+--J'ai frappé à toutes les portes.\r
+\r
+--Eh bien?\r
+\r
+--Partout on m'a chassé.\r
+\r
+La «bonne femme» toucha le bras de l'homme et lui montra de l'autre côté\r
+de la place une petite maison basse à côté de l'évêché.\r
+\r
+--Vous avez, reprit-elle, frappé à toutes les portes?\r
+\r
+--Oui.\r
+\r
+--Avez-vous frappé à celle-là?\r
+\r
+--Non.\r
+\r
+--Frappez-y.\r

+Chapitre II\r
+\r
+La prudence conseillée à la sagesse\r
+\r
+\r
+Ce soir-là, M. l'évêque de Digne, après sa promenade en ville, était\r
+resté assez tard enfermé dans sa chambre. Il s'occupait d'un grand\r
+travail sur les _Devoirs_, lequel est malheureusement demeuré inachevé.\r
+Il dépouillait soigneusement tout ce que les Pères et les Docteurs ont\r
+dit sur cette grave matière. Son livre était divisé en deux parties;\r
+premièrement les devoirs de tous, deuxièmement les devoirs de chacun,\r
+selon la classe à laquelle il appartient. Les devoirs de tous sont les\r
+grands devoirs. Il y en a quatre. Saint Matthieu les indique: devoirs\r
+envers Dieu (Matth., VI), devoirs envers soi-même (Matth., V, 29, 30),\r
+devoirs envers le prochain (Matth., VII, 12), devoirs envers les\r
+créatures (Matth., VI, 20, 25). Pour les autres devoirs, l'évêque les\r
+avait trouvés indiqués et prescrits ailleurs; aux souverains et aux\r
+sujets, dans l'Épître aux Romains; aux magistrats, aux épouses, aux\r
+mères et aux jeunes hommes, par saint Pierre; aux maris, aux pères, aux\r
+enfants et aux serviteurs, dans l'Épître aux Éphésiens; aux fidèles,\r
+dans l'Épître aux Hébreux; aux vierges, dans l'Épître aux Corinthiens.\r
+Il faisait laborieusement de toutes ces prescriptions un ensemble\r
+harmonieux qu'il voulait présenter aux âmes.\r
+\r
+Il travaillait encore à huit heures, écrivant assez incommodément sur de\r
+petits carrés de papier avec un gros livre ouvert sur ses genoux, quand\r
+madame Magloire entra, selon son habitude, pour prendre l'argenterie\r
+dans le placard près du lit. Un moment après, l'évêque, sentant que le\r
+couvert était mis et que sa soeur l'attendait peut-être, ferma son\r
+livre, se leva de sa table et entra dans la salle à manger.\r
+\r
+La salle à manger était une pièce oblongue à cheminée, avec porte sur la\r
+rue (nous l'avons dit), et fenêtre sur le jardin.\r
+\r
+Madame Magloire achevait en effet de mettre le couvert.\r
+\r
+Tout en vaquant au service, elle causait avec mademoiselle Baptistine.\r
+\r
+Une lampe était sur la table; la table était près de la cheminée. Un\r
+assez bon feu était allumé.\r
+\r
+On peut se figurer facilement ces deux femmes qui avaient toutes deux\r
+passé soixante ans: madame Magloire petite, grasse, vive; mademoiselle\r
+Baptistine, douce, mince, frêle, un peu plus grande que son frère, vêtue\r
+d'une robe de soie puce, couleur à la mode en 1806, qu'elle avait\r
+achetée alors à Paris et qui lui durait encore. Pour emprunter des\r
+locutions vulgaires qui ont le mérite de dire avec un seul mot une idée\r
+qu'une page suffirait à peine à exprimer, madame Magloire avait l'air\r
+d'une _paysanne_ et mademoiselle Baptistine d'une _dame_. Madame\r
+Magloire avait un bonnet blanc à tuyaux, au cou une jeannette d'or, le\r
+seul bijou de femme qu'il y eût dans la maison, un fichu très blanc\r
+sortant de la robe de bure noire à manches larges et courtes, un tablier\r
+de toile de coton à carreaux rouges et verts, noué à la ceinture d'un\r
+ruban vert, avec pièce d'estomac pareille rattachée par deux épingles\r
+aux deux coins d'en haut, aux pieds de gros souliers et des bas jaunes\r
+comme les femmes de Marseille. La robe de mademoiselle Baptistine était\r
+coupée sur les patrons de 1806, taille courte, fourreau étroit, manches\r
+à épaulettes, avec pattes et boutons. Elle cachait ses cheveux gris sous\r
+une perruque frisée dite à _l'enfant_. Madame Magloire avait l'air\r
+intelligent, vif et bon; les deux angles de sa bouche inégalement\r
+relevés et la lèvre supérieure plus grosse que la lèvre inférieure lui\r
+donnaient quelque chose de bourru et d'impérieux. Tant que monseigneur\r
+se taisait, elle lui parlait résolument avec un mélange de respect et de\r
+liberté; mais dès que monseigneur parlait, on a vu cela, elle obéissait\r
+passivement comme mademoiselle. Mademoiselle Baptistine ne parlait même\r
+pas. Elle se bornait à obéir et à complaire. Même quand elle était\r
+jeune, elle n'était pas jolie, elle avait de gros yeux bleus à fleur de\r
+tête et le nez long et busqué; mais tout son visage, toute sa personne,\r
+nous l'avons dit en commençant, respiraient une ineffable bonté. Elle\r
+avait toujours été prédestinée à la mansuétude; mais la foi, la charité,\r
+l'espérance, ces trois vertus qui chauffent doucement l'âme, avaient\r
+élevé peu à peu cette mansuétude jusqu'à la sainteté. La nature n'en\r
+avait fait qu'une brebis, la religion en avait fait un ange. Pauvre\r
+sainte fille! doux souvenir disparu! Mademoiselle Baptistine a depuis\r
+raconté tant de fois ce qui s'était passé à l'évêché cette soirée-là,\r
+que plusieurs personnes qui vivent encore s'en rappellent les moindres\r
+détails.\r
+\r
+Au moment où M. l'évêque entra, madame Magloire parlait avec quelque\r
+vivacité. Elle entretenait _mademoiselle_ d'un sujet qui lui était\r
+familier et auquel l'évêque était accoutumé. Il s'agissait du loquet de\r
+la porte d'entrée.\r
+\r
+Il paraît que, tout en allant faire quelques provisions pour le souper,\r
+madame Magloire avait entendu dire des choses en divers lieux. On\r
+parlait d'un rôdeur de mauvaise mine; qu'un vagabond suspect serait\r
+arrivé, qu'il devait être quelque part dans la ville, et qu'il se\r
+pourrait qu'il y eût de méchantes rencontres pour ceux qui s'aviseraient\r
+de rentrer tard chez eux cette nuit-là. Que la police était bien mal\r
+faite du reste, attendu que M. le préfet et M. le maire ne s'aimaient\r
+pas, et cherchaient à se nuire en faisant arriver des événements. Que\r
+c'était donc aux gens sages à faire la police eux-mêmes et à se bien\r
+garder, et qu'il faudrait avoir soin de dûment clore, verrouiller et\r
+barricader sa maison, _et de bien fermer ses portes_.\r
+\r
+Madame Magloire appuya sur ce dernier mot; mais l'évêque venait de sa\r
+chambre où il avait eu assez froid, il s'était assis devant la cheminée\r
+et se chauffait, et puis il pensait à autre chose. Il ne releva pas le\r
+mot à effet que madame Magloire venait de laisser tomber. Elle le\r
+répéta. Alors, mademoiselle Baptistine, voulant satisfaire madame\r
+Magloire sans déplaire à son frère, se hasarda à dire timidement:\r
+\r
+--Mon frère, entendez-vous ce que dit madame Magloire?\r
+\r
+--J'en ai entendu vaguement quelque chose, répondit l'évêque.\r
+\r
+Puis tournant à demi sa chaise, mettant ses deux mains sur ses genoux,\r
+et levant vers la vieille servante son visage cordial et facilement\r
+joyeux, que le feu éclairait d'en bas:\r
+\r
+--Voyons. Qu'y a-t-il? qu'y a-t-il? Nous sommes donc dans quelque gros\r
+danger?\r
+\r
+Alors madame Magloire recommença toute l'histoire, en l'exagérant\r
+quelque peu, sans s'en douter. Il paraîtrait qu'un bohémien, un\r
+va-nu-pieds, une espèce de mendiant dangereux serait en ce moment dans\r
+la ville. Il s'était présenté pour loger chez Jacquin Labarre qui\r
+n'avait pas voulu le recevoir. On l'avait vu arriver par le boulevard\r
+Gassendi et rôder dans les rues à la brume. Un homme de sac et de corde\r
+avec une figure terrible.\r
+\r
+--Vraiment? dit l'évêque.\r
+\r
+Ce consentement à l'interroger encouragea madame Magloire; cela lui\r
+semblait indiquer que l'évêque n'était pas loin de s'alarmer; elle\r
+poursuivit triomphante:\r
+\r
+--Oui, monseigneur. C'est comme cela. Il y aura quelque malheur cette\r
+nuit dans la ville. Tout le monde le dit. Avec cela que la police est si\r
+mal faite (répétition inutile). Vivre dans un pays de montagnes, et\r
+n'avoir pas même de lanternes la nuit dans les rues! On sort. Des fours,\r
+quoi! Et je dis, monseigneur, et mademoiselle que voilà dit comme moi....\r
+\r
+--Moi, interrompit la soeur, je ne dis rien. Ce que mon frère fait est\r
+bien fait.\r
+\r
+Madame Magloire continua comme s'il n'y avait pas eu de protestation:\r
+\r
+--Nous disons que cette maison-ci n'est pas sûre du tout; que, si\r
+monseigneur le permet, je vais aller dire à Paulin Musebois, le\r
+serrurier, qu'il vienne remettre les anciens verrous de la porte; on les\r
+a là, c'est une minute; et je dis qu'il faut des verrous, monseigneur,\r
+ne serait-ce que pour cette nuit; car je dis qu'une porte qui s'ouvre du\r
+dehors avec un loquet, par le premier passant venu, rien n'est plus\r
+terrible; avec cela que monseigneur a l'habitude de toujours dire\r
+d'entrer, et que d'ailleurs, même au milieu de la nuit, ô mon Dieu! on\r
+n'a pas besoin d'en demander la permission....\r
+\r
+En ce moment, on frappa à la porte un coup assez violent.\r
+\r
+--Entrez, dit l'évêque.\r
+\r
+\r
+\r
+\r
+Chapitre III\r
+\r
+Héroïsme de l'obéissance passive\r
+\r
+\r
+La porte s'ouvrit.\r
+\r
+Elle s'ouvrit vivement, toute grande, comme si quelqu'un la poussait\r
+avec énergie et résolution.\r
+\r
+Un homme entra.\r
+\r
+Cet homme, nous le connaissons déjà. C'est le voyageur que nous avons vu\r
+tout à l'heure errer cherchant un gîte.\r
+\r
+Il entra, fit un pas, et s'arrêta, laissant la porte ouverte derrière\r
+lui. Il avait son sac sur l'épaule, son bâton à la main, une expression\r
+rude, hardie, fatiguée et violente dans les yeux. Le feu de la cheminée\r
+l'éclairait. Il était hideux. C'était une sinistre apparition.\r
+\r
+Madame Magloire n'eut pas même la force de jeter un cri. Elle\r
+tressaillit, et resta béante.\r
+\r
+Mademoiselle Baptistine se retourna, aperçut l'homme qui entrait et se\r
+dressa à demi d'effarement, puis, ramenant peu à peu sa tête vers la\r
+cheminée, elle se mit à regarder son frère et son visage redevint\r
+profondément calme et serein.\r
+\r
+L'évêque fixait sur l'homme un oeil tranquille.\r
+\r
+Comme il ouvrait la bouche, sans doute pour demander au nouveau venu ce\r
+qu'il désirait, l'homme appuya ses deux mains à la fois sur son bâton,\r
+promena ses yeux tour à tour sur le vieillard et les femmes, et, sans\r
+attendre que l'évêque parlât, dit d'une voix haute:\r
+\r
+--Voici. Je m'appelle Jean Valjean. Je suis un galérien. J'ai passé\r
+dix-neuf ans au bagne. Je suis libéré depuis quatre jours et en route\r
+pour Pontarlier qui est ma destination. Quatre jours et que je marche\r
+depuis Toulon. Aujourd'hui, j'ai fait douze lieues à pied. Ce soir, en\r
+arrivant dans ce pays, j'ai été dans une auberge, on m'a renvoyé à cause\r
+de mon passeport jaune que j'avais montré à la mairie. Il avait fallu.\r
+J'ai été à une autre auberge. On m'a dit: Va-t-en! Chez l'un, chez\r
+l'autre. Personne n'a voulu de moi. J'ai été à la prison, le guichetier\r
+n'a pas ouvert. J'ai été dans la niche d'un chien. Ce chien m'a mordu et\r
+m'a chassé, comme s'il avait été un homme. On aurait dit qu'il savait\r
+qui j'étais. Je m'en suis allé dans les champs pour coucher à la belle\r
+étoile. Il n'y avait pas d'étoile. J'ai pensé qu'il pleuvrait, et qu'il\r
+n'y avait pas de bon Dieu pour empêcher de pleuvoir, et je suis rentré\r
+dans la ville pour y trouver le renfoncement d'une porte. Là, dans la\r
+place, j'allais me coucher sur une pierre. Une bonne femme m'a montré\r
+votre maison et m'a dit: «Frappe là». J'ai frappé. Qu'est-ce que c'est\r
+ici? Êtes-vous une auberge? J'ai de l'argent. Ma masse. Cent neuf francs\r
+quinze sous que j'ai gagnés au bagne par mon travail en dix-neuf ans. Je\r
+payerai. Qu'est-ce que cela me fait? J'ai de l'argent. Je suis très\r
+fatigué, douze lieues à pied, j'ai bien faim. Voulez-vous que je reste?\r
+\r
+--Madame Magloire, dit l'évêque, vous mettrez un couvert de plus.\r
+\r
+L'homme fit trois pas et s'approcha de la lampe qui était sur la table.\r
+\r
+--Tenez, reprit-il, comme s'il n'avait pas bien compris, ce n'est pas\r
+ça. Avez-vous entendu? Je suis un galérien. Un forçat. Je viens des\r
+galères.\r
+\r
+Il tira de sa poche une grande feuille de papier jaune qu'il déplia.\r
+\r
+--Voilà mon passeport. Jaune, comme vous voyez. Cela sert à me faire\r
+chasser de partout où je suis. Voulez-vous lire? Je sais lire, moi. J'ai\r
+appris au bagne. Il y a une école pour ceux qui veulent. Tenez, voilà ce\r
+qu'on a mis sur le passeport: «Jean Valjean, forçat libéré, natif\r
+de...--cela vous est égal...--Est resté dix-neuf ans au bagne. Cinq ans\r
+pour vol avec effraction. Quatorze ans pour avoir tenté de s'évader\r
+quatre fois. Cet homme est très dangereux.»--Voilà! Tout le monde m'a\r
+jeté dehors. Voulez-vous me recevoir, vous? Est-ce une auberge?\r
+Voulez-vous me donner à manger et à coucher? Avez-vous une écurie?\r
+\r
+--Madame Magloire, dit l'évêque, vous mettrez des draps blancs au lit de\r
+l'alcôve.\r
+\r
+Nous avons déjà expliqué de quelle nature était l'obéissance des deux\r
+femmes.\r
+\r
+Madame Magloire sortit pour exécuter ces ordres. L'évêque se tourna vers\r
+l'homme.\r
+\r
+--Monsieur, asseyez-vous et chauffez-vous. Nous allons souper dans un\r
+instant, et l'on fera votre lit pendant que vous souperez.\r
+\r
+Ici l'homme comprit tout à fait. L'expression de son visage, jusqu'alors\r
+sombre et dure, s'empreignit de stupéfaction, de doute, de joie, et\r
+devint extraordinaire. Il se mit à balbutier comme un homme fou:\r
+\r
+--Vrai? quoi? vous me gardez? vous ne me chassez pas! un forçat! Vous\r
+m'appelez monsieur! vous ne me tutoyez pas! Va-t-en, chien! qu'on me dit\r
+toujours. Je croyais bien que vous me chasseriez. Aussi j'avais dit tout\r
+de suite qui je suis. Oh! la brave femme qui m'a enseigné ici! Je vais\r
+souper! un lit! Un lit avec des matelas et des draps! comme tout le\r
+monde! il y a dix-neuf ans que je n'ai couché dans un lit! Vous voulez\r
+bien que je ne m'en aille pas! Vous êtes de dignes gens! D'ailleurs j'ai\r
+de l'argent. Je payerai bien. Pardon, monsieur l'aubergiste, comment\r
+vous appelez-vous? Je payerai tout ce qu'on voudra. Vous êtes un brave\r
+homme. Vous êtes aubergiste, n'est-ce pas?\r
+\r
+--Je suis, dit l'évêque, un prêtre qui demeure ici.\r
+\r
+--Un prêtre! reprit l'homme. Oh! un brave homme de prêtre! Alors vous ne\r
+me demandez pas d'argent? Le curé, n'est-ce pas? le curé de cette grande\r
+église? Tiens! c'est vrai, que je suis bête! je n'avais pas vu votre\r
+calotte!\r
+\r
+Tout en parlant, il avait déposé son sac et son bâton dans un coin, puis\r
+remis son passeport dans sa poche, et il s'était assis. Mademoiselle\r
+Baptistine le considérait avec douceur. Il continua:\r
+\r
+--Vous êtes humain, monsieur le curé. Vous n'avez pas de mépris. C'est\r
+bien bon un bon prêtre. Alors vous n'avez pas besoin que je paye?\r
+\r
+--Non, dit l'évêque, gardez votre argent. Combien avez-vous? ne\r
+m'avez-vous pas dit cent neuf francs?\r
+\r
+--Quinze sous, ajouta l'homme.\r
+\r
+--Cent neuf francs quinze sous. Et combien de temps avez-vous mis à\r
+gagner cela?\r
+\r
+--Dix-neuf ans.\r
+\r
+--Dix-neuf ans!\r
+\r
+L'évêque soupira profondément.\r
+\r
+L'homme poursuivit:\r
+\r
+--J'ai encore tout mon argent. Depuis quatre jours je n'ai dépensé que\r
+vingt-cinq sous que j'ai gagnés en aidant à décharger des voitures à\r
+Grasse. Puisque vous êtes abbé, je vais vous dire, nous avions un\r
+aumônier au bagne. Et puis un jour j'ai vu un évêque. Monseigneur, qu'on\r
+appelle. C'était l'évêque de la Majore, à Marseille. C'est le curé qui\r
+est sur les curés. Vous savez, pardon, je dis mal cela, mais pour moi,\r
+c'est si loin!--Vous comprenez, nous autres! Il a dit la messe au milieu\r
+du bagne, sur un autel, il avait une chose pointue, en or, sur la tête.\r
+Au grand jour de midi, cela brillait. Nous étions en rang. Des trois\r
+côtés. Avec les canons, mèche allumée, en face de nous. Nous ne voyions\r
+pas bien. Il a parlé, mais il était trop au fond, nous n'entendions pas.\r
+Voilà ce que c'est qu'un évêque.\r
+\r
+Pendant qu'il parlait, l'évêque était allé pousser la porte qui était\r
+restée toute grande ouverte.\r
+\r
+Madame Magloire rentra. Elle apportait un couvert qu'elle mit sur la\r
+table.\r
+\r
+--Madame Magloire, dit l'évêque, mettez ce couvert le plus près possible\r
+du feu.\r
+\r
+Et se tournant vers son hôte:\r
+\r
+--Le vent de nuit est dur dans les Alpes. Vous devez avoir froid,\r
+monsieur?\r
+\r
+Chaque fois qu'il disait ce mot monsieur, avec sa voix doucement grave\r
+et de si bonne compagnie, le visage de l'homme s'illuminait. Monsieur à\r
+un forçat, c'est un verre d'eau à un naufragé de la Méduse. L'ignominie\r
+a soif de considération.\r
+\r
+--Voici, reprit l'évêque, une lampe qui éclaire bien mal.\r
+\r
+Madame Magloire comprit, et elle alla chercher sur la cheminée de la\r
+chambre à coucher de monseigneur les deux chandeliers d'argent qu'elle\r
+posa sur la table tout allumés.\r
+\r
+--Monsieur le curé, dit l'homme, vous êtes bon. Vous ne me méprisez pas.\r
+Vous me recevez chez vous. Vous allumez vos cierges pour moi. Je ne vous\r
+ai pourtant pas caché d'où je viens et que je suis un homme malheureux.\r
+\r
+L'évêque, assis près de lui, lui toucha doucement la main.\r
+\r
+--Vous pouviez ne pas me dire qui vous étiez.\r
+\r
+Ce n'est pas ici ma maison, c'est la maison de Jésus-Christ. Cette porte\r
+ne demande pas à celui qui entre s'il a un nom, mais s'il a une douleur.\r
+Vous souffrez; vous avez faim et soif; soyez le bienvenu. Et ne me\r
+remerciez pas, ne me dites pas que je vous reçois chez moi. Personne\r
+n'est ici chez soi, excepté celui qui a besoin d'un asile. Je vous le\r
+dis à vous qui passez, vous êtes ici chez vous plus que moi-même. Tout\r
+ce qui est ici est à vous. Qu'ai-je besoin de savoir votre nom?\r
+D'ailleurs, avant que vous me le disiez, vous en avez un que je savais.\r
+\r
+L'homme ouvrit des yeux étonnés.\r
+\r
+--Vrai? vous saviez comment je m'appelle?\r
+\r
+--Oui, répondit l'évêque, vous vous appelez mon frère.\r
+\r
+--Tenez, monsieur le curé! s'écria l'homme, j'avais bien faim en entrant\r
+ici; mais vous êtes si bon qu'à présent je ne sais plus ce que j'ai;\r
+cela m'a passé.\r
+\r
+L'évêque le regarda et lui dit:\r
+\r
+--Vous avez bien souffert?\r
+\r
+--Oh! la casaque rouge, le boulet au pied, une planche pour dormir, le\r
+chaud, le froid, le travail, la chiourme, les coups de bâton! La double\r
+chaîne pour rien. Le cachot pour un mot. Même malade au lit, la chaîne.\r
+Les chiens, les chiens sont plus heureux! Dix-neuf ans! J'en ai\r
+quarante-six. À présent, le passeport jaune! Voilà.\r
+\r
+--Oui, reprit l'évêque, vous sortez d'un lieu de tristesse. Écoutez. Il\r
+y aura plus de joie au ciel pour le visage en larmes d'un pécheur\r
+repentant que pour la robe blanche de cent justes. Si vous sortez de ce\r
+lieu douloureux avec des pensées de haine et de colère contre les\r
+hommes, vous êtes digne de pitié; si vous en sortez avec des pensées de\r
+bienveillance, de douceur et de paix, vous valez mieux qu'aucun de nous.\r
+\r
+Cependant madame Magloire avait servi le souper. Une soupe faite avec de\r
+l'eau, de l'huile, du pain et du sel, un peu de lard, un morceau de\r
+viande de mouton, des figues, un fromage frais, et un gros pain de\r
+seigle. Elle avait d'elle-même ajouté à l'ordinaire de M. l'évêque une\r
+bouteille de vieux vin de Mauves.\r
+\r
+Le visage de l'évêque prit tout à coup cette expression de gaîté propre\r
+aux natures hospitalières:\r
+\r
+--À table! dit-il vivement.\r
+\r
+Comme il en avait coutume lorsque quelque étranger soupait avec lui, il\r
+fit asseoir l'homme à sa droite. Mademoiselle Baptistine, parfaitement\r
+paisible et naturelle, prit place à sa gauche.\r
+\r
+L'évêque dit le bénédicité, puis servit lui-même la soupe, selon son\r
+habitude. L'homme se mit à manger avidement.\r
+\r
+Tout à coup l'évêque dit:\r
+\r
+--Mais il me semble qu'il manque quelque chose sur cette table.\r
+\r
+Madame Magloire en effet n'avait mis que les trois couverts absolument\r
+nécessaires. Or c'était l'usage de la maison, quand l'évêque avait\r
+quelqu'un à souper, de disposer sur la nappe les six couverts d'argent,\r
+étalage innocent. Ce gracieux semblant de luxe était une sorte\r
+d'enfantillage plein de charme dans cette maison douce et sévère qui\r
+élevait la pauvreté jusqu'à la dignité.\r
+\r
+Madame Magloire comprit l'observation, sortit sans dire un mot, et un\r
+moment après les trois couverts réclamés par l'évêque brillaient sur la\r
+nappe, symétriquement arrangés devant chacun des trois convives.\r

+Détails sur les fromageries de Pontarlier\r
+\r
+\r
+Maintenant, pour donner une idée de ce qui se passa à cette table, nous\r
+ne saurions mieux faire que de transcrire ici un passage d'une lettre de\r
+mademoiselle Baptistine à madame de Boischevron, où la conversation du\r
+forçat et de l'évêque est racontée avec une minutie naïve:\r
+\r
+ * * * * *\r
+\r
+«...Cet homme ne faisait aucune attention à personne. Il mangeait avec\r
+une voracité d'affamé. Cependant, après la soupe, il a dit:\r
+\r
+«--Monsieur le curé du bon Dieu, tout ceci est encore bien trop bon pour\r
+moi, mais je dois dire que les rouliers qui n'ont pas voulu me laisser\r
+manger avec eux font meilleure chère que vous.\r
+\r
+«Entre nous, l'observation m'a un peu choquée. Mon frère a répondu:\r
+\r
+«--Ils ont plus de fatigue que moi.\r
+\r
+«--Non, a repris cet homme, ils ont plus d'argent. Vous êtes pauvre. Je\r
+vois bien. Vous n'êtes peut-être pas même curé. Êtes-vous curé\r
+seulement? Ah! par exemple, si le bon Dieu était juste, vous devriez\r
+bien être curé.\r
+\r
+«--Le bon Dieu est plus que juste, a dit mon frère.\r
+\r
+«Un moment après il a ajouté:\r
+\r
+«--Monsieur Jean Valjean, c'est à Pontarlier que vous allez?\r
+\r
+«--Avec itinéraire obligé.\r
+\r
+«Je crois bien que c'est comme cela que l'homme a dit. Puis il a\r
+continué:\r
+\r
+«--Il faut que je sois en route demain à la pointe du jour. Il fait dur\r
+voyager. Si les nuits sont froides, les journées sont chaudes.\r
+\r
+«--Vous allez là, a repris mon frère, dans un bon pays. À la révolution,\r
+ma famille a été ruinée, je me suis réfugié en Franche-Comté d'abord, et\r
+j'y ai vécu quelque temps du travail de mes bras. J'avais de la bonne\r
+volonté. J'ai trouvé à m'y occuper. On n'a qu'à choisir. Il y a des\r
+papeteries, des tanneries, des distilleries, des huileries, des\r
+fabriques d'horlogerie en grand, des fabriques d'acier, des fabriques de\r
+cuivre, au moins vingt usines de fer, dont quatre à Lods, à Châtillon, à\r
+Audincourt et à Beure qui sont très considérables....\r
+\r
+«Je crois ne pas me tromper et que ce sont bien là les noms que mon\r
+frère a cités, puis il s'est interrompu et m'a adressé la parole:\r
+\r
+«--Chère soeur, n'avons-nous pas des parents dans ce pays-là?\r
+\r
+«J'ai répondu:\r
+\r
+«--Nous en avions, entre autres M. de Lucenet qui était capitaine des\r
+portes à Pontarlier dans l'ancien régime.\r
+\r
+«--Oui, a repris mon frère, mais en 93 on n'avait plus de parents, on\r
+n'avait que ses bras. J'ai travaillé. Ils ont dans le pays de\r
+Pontarlier, où vous allez, monsieur Valjean, une industrie toute\r
+patriarcale et toute charmante, ma soeur. Ce sont leurs fromageries\r
+qu'ils appellent fruitières.\r
+\r
+«Alors mon frère, tout en faisant manger cet homme, lui a expliqué très\r
+en détail ce que c'étaient que les fruitières de Pontarlier;--qu'on en\r
+distinguait deux sortes:--les _grosses granges_, qui sont aux riches, et\r
+où il y a quarante ou cinquante vaches, lesquelles produisent sept à\r
+huit milliers de fromages par été; les _fruitières d'association_, qui\r
+sont aux pauvres; ce sont les paysans de la moyenne montagne qui mettent\r
+leurs vaches en commun et partagent les produits.--Ils prennent à leurs\r
+gages un fromager qu'ils appellent le grurin;--le grurin reçoit le lait\r
+des associés trois fois par jour et marque les quantités sur une taille\r
+double;--c'est vers la fin d'avril que le travail des fromageries\r
+commence; c'est vers la mi-juin que les fromagers conduisent leurs\r
+vaches dans la montagne.\r
+\r
+«L'homme se ranimait tout en mangeant. Mon frère lui faisait boire de ce\r
+bon vin de Mauves dont il ne boit pas lui-même parce qu'il dit que c'est\r
+du vin cher. Mon frère lui disait tous ces détails avec cette gaîté\r
+aisée que vous lui connaissez, entremêlant ses paroles de façons\r
+gracieuses pour moi. Il est beaucoup revenu sur ce bon état de grurin,\r
+comme s'il eût souhaité que cet homme comprît, sans le lui conseiller\r
+directement et durement, que ce serait un asile pour lui. Une chose m'a\r
+frappée. Cet homme était ce que je vous ai dit. Eh bien! mon frère,\r
+pendant tout le souper, ni de toute la soirée, à l'exception de quelques\r
+paroles sur Jésus quand il est entré, n'a pas dit un mot qui pût\r
+rappeler à cet homme qui il était ni apprendre à cet homme qui était mon\r
+frère. C'était bien une occasion en apparence de faire un peu de sermon\r
+et d'appuyer l'évêque sur le galérien pour laisser la marque du passage.\r
+Il eût paru peut-être à un autre que c'était le cas, ayant ce malheureux\r
+sous la main, de lui nourrir l'âme en même temps que le corps et de lui\r
+faire quelque reproche assaisonné de morale et de conseil, ou bien un\r
+peu de commisération avec exhortation de se mieux conduire à l'avenir.\r
+Mon frère ne lui a même pas demandé de quel pays il était, ni son\r
+histoire. Car dans son histoire il y a sa faute, et mon frère semblait\r
+éviter tout ce qui pouvait l'en faire souvenir. C'est au point qu'à un\r
+certain moment, comme mon frère parlait des montagnards de Pontarlier,\r
+qui ont _un doux travail près du ciel et qui_, ajoutait-il, _sont\r
+heureux parce qu'ils sont innocents_, il s'est arrêté court, craignant\r
+qu'il n'y eût dans ce mot qui lui échappait quelque chose qui pût\r
+froisser l'homme. À force d'y réfléchir, je crois avoir compris ce qui\r
+se passait dans le coeur de mon frère. Il pensait sans doute que cet\r
+homme, qui s'appelle Jean Valjean, n'avait que trop sa misère présente à\r
+l'esprit, que le mieux était de l'en distraire, et de lui faire croire,\r
+ne fût-ce qu'un moment, qu'il était une personne comme une autre, en\r
+étant pour lui tout ordinaire. N'est-ce pas là en effet bien entendre la\r
+charité? N'y a-t-il pas, bonne madame, quelque chose de vraiment\r
+évangélique dans cette délicatesse qui s'abstient de sermon, de morale\r
+et d'allusion, et la meilleure pitié, quand un homme a un point\r
+douloureux, n'est-ce pas de n'y point toucher du tout? Il m'a semblé que\r
+ce pouvait être là la pensée intérieure de mon frère. Dans tous les cas,\r
+ce que je puis dire, c'est que, s'il a eu toutes ces idées, il n'en a\r
+rien marqué, même pour moi; il a été d'un bout à l'autre le même homme\r
+que tous les soirs, et il a soupé avec ce Jean Valjean du même air et de\r
+la même façon qu'il aurait soupé avec M. Gédéon Le Prévost ou avec M. le\r
+curé de la paroisse.\r
+\r
+«Vers la fin, comme nous étions aux figues, on a cogné à la porte.\r
+C'était la mère Gerbaud avec son petit dans ses bras. Mon frère a baisé\r
+l'enfant au front, et m'a emprunté quinze sous que j'avais sur moi pour\r
+les donner à la mère Gerbaud. L'homme pendant ce temps-là ne faisait pas\r
+grande attention. Il ne parlait plus et paraissait très fatigué. La\r
+pauvre vieille Gerbaud partie, mon frère a dit les grâces, puis il s'est\r
+tourné vers cet homme, et il lui a dit: Vous devez avoir bien besoin de\r
+votre lit. Madame Magloire a enlevé le couvert bien vite. J'ai compris\r
+qu'il fallait nous retirer pour laisser dormir ce voyageur, et nous\r
+sommes montées toutes les deux. J'ai cependant envoyé madame Magloire un\r
+instant après porter sur le lit de cet homme une peau de chevreuil de la\r
+Forêt-Noire qui est dans ma chambre. Les nuits sont glaciales, et cela\r
+tient chaud. C'est dommage que cette peau soit vieille; tout le poil\r
+s'en va. Mon frère l'a achetée du temps qu'il était en Allemagne, à\r
+Tottlingen, près des sources du Danube, ainsi que le petit couteau à\r
+manche d'ivoire dont je me sers à table.\r
+\r
+«Madame Magloire est remontée presque tout de suite, nous nous sommes\r
+mises à prier Dieu dans le salon où l'on étend le linge, et puis nous\r
+sommes rentrées chacune dans notre chambre sans nous rien dire.»\r

+\r
+Tranquillité\r
+\r
+\r
+Après avoir donné le bonsoir à sa soeur, monseigneur Bienvenu prit sur\r
+la table un des deux flambeaux d'argent, remit l'autre à son hôte, et\r
+lui dit:\r
+\r
+--Monsieur, je vais vous conduire à votre chambre.\r
+\r
+L'homme le suivit.\r
+\r
+Comme on a pu le remarquer dans ce qui a été dit plus haut, le logis\r
+était distribué de telle sorte que, pour passer dans l'oratoire où était\r
+l'alcôve ou pour en sortir, il fallait traverser la chambre à coucher de\r
+l'évêque.\r
+\r
+Au moment où ils traversaient cette chambre, madame Magloire serrait\r
+l'argenterie dans le placard qui était au chevet du lit. C'était le\r
+dernier soin qu'elle prenait chaque soir avant de s'aller coucher.\r
+\r
+L'évêque installa son hôte dans l'alcôve. Un lit blanc et frais y était\r
+dressé. L'homme posa le flambeau sur une petite table.\r
+\r
+--Allons, dit l'évêque, faites une bonne nuit. Demain matin, avant de\r
+partir, vous boirez une tasse de lait de nos vaches tout chaud.\r
+\r
+--Merci, monsieur l'abbé, dit l'homme.\r
+\r
+À peine eut-il prononcé ces paroles pleines de paix que, tout à coup et\r
+sans transition, il eut un mouvement étrange et qui eût glacé\r
+d'épouvante les deux saintes filles si elles en eussent été témoins.\r
+Aujourd'hui même il nous est difficile de nous rendre compte de ce qui\r
+le poussait en ce moment. Voulait-il donner un avertissement ou jeter\r
+une menace? Obéissait-il simplement à une sorte d'impulsion instinctive\r
+et obscure pour lui-même? Il se tourna brusquement vers le vieillard,\r
+croisa les bras, et, fixant sur son hôte un regard sauvage, il s'écria\r
+d'une voix rauque:\r
+\r
+--Ah çà! décidément! vous me logez chez vous près de vous comme cela!\r
+\r
+Il s'interrompit et ajouta avec un rire où il y avait quelque chose de\r
+monstrueux:\r
+\r
+--Avez-vous bien fait toutes vos réflexions? Qui est-ce qui vous dit que\r
+je n'ai pas assassiné?\r
+\r
+L'évêque leva les yeux vers le plafond et répondit:\r
+\r
+--Cela regarde le bon Dieu.\r
+\r
+Puis, gravement et remuant les lèvres comme quelqu'un qui prie ou qui se\r
+parle à lui-même, il dressa les deux doigts de sa main droite et bénit\r
+l'homme qui ne se courba pas, et, sans tourner la tête et sans regarder\r
+derrière lui, il rentra dans sa chambre.\r
+\r
+Quand l'alcôve était habitée, un grand rideau de serge tiré de part en\r
+part dans l'oratoire cachait l'autel. L'évêque s'agenouilla en passant\r
+devant ce rideau et fit une courte prière.\r
+\r
+Un moment après, il était dans son jardin, marchant, rêvant,\r
+contemplant, l'âme et la pensée tout entières à ces grandes choses\r
+mystérieuses que Dieu montre la nuit aux yeux qui restent ouverts.\r
+\r
+Quant à l'homme, il était vraiment si fatigué qu'il n'avait même pas\r
+profité de ces bons draps blancs. Il avait soufflé sa bougie avec sa\r
+narine à la manière des forçats et s'était laissé tomber tout habillé\r
+sur le lit, où il s'était tout de suite profondément endormi.\r
+\r
+Minuit sonnait comme l'évêque rentrait de son jardin dans son\r
+appartement.\r
+\r
+Quelques minutes après, tout dormait dans la petite maison.\r
+\r
+\r
+\r
+\r
+Chapitre VI\r
+\r
+Jean Valjean\r
+\r
+\r
+Vers le milieu de la nuit, Jean Valjean se réveilla.\r
+\r
+Jean Valjean était d'une pauvre famille de paysans de la Brie. Dans son\r
+enfance, il n'avait pas appris à lire. Quand il eut l'âge d'homme, il\r
+était émondeur à Faverolles. Sa mère s'appelait Jeanne Mathieu; son père\r
+s'appelait Jean Valjean, ou Vlajean, sobriquet probablement, et\r
+contraction de _Voilà Jean_.\r
+\r
+Jean Valjean était d'un caractère pensif sans être triste, ce qui est le\r
+propre des natures affectueuses. Somme toute, pourtant, c'était quelque\r
+chose d'assez endormi et d'assez insignifiant, en apparence du moins,\r
+que Jean Valjean. Il avait perdu en très bas âge son père et sa mère. Sa\r
+mère était morte d'une fièvre de lait mal soignée. Son père, émondeur\r
+comme lui, s'était tué en tombant d'un arbre. Il n'était resté à Jean\r
+Valjean qu'une soeur plus âgée que lui, veuve, avec sept enfants, filles\r
+et garçons. Cette soeur avait élevé Jean Valjean, et tant qu'elle eut\r
+son mari elle logea et nourrit son jeune frère. Le mari mourut. L'aîné\r
+des sept enfants avait huit ans, le dernier un an. Jean Valjean venait\r
+d'atteindre, lui, sa vingt-cinquième année. Il remplaça le père, et\r
+soutint à son tour sa soeur qui l'avait élevé. Cela se fit simplement,\r
+comme un devoir, même avec quelque chose de bourru de la part de Jean\r
+Valjean. Sa jeunesse se dépensait ainsi dans un travail rude et mal\r
+payé. On ne lui avait jamais connu de «bonne amie» dans le pays. Il\r
+n'avait pas eu le temps d'être amoureux.\r
+\r
+Le soir il rentrait fatigué et mangeait sa soupe sans dire un mot. Sa\r
+soeur, mère Jeanne, pendant qu'il mangeait, lui prenait souvent dans son\r
+écuelle le meilleur de son repas, le morceau de viande, la tranche de\r
+lard le coeur de chou, pour le donner à quelqu'un de ses enfants; lui,\r
+mangeant toujours, penché sur la table, presque la tête dans sa soupe,\r
+ses longs cheveux tombant autour de son écuelle et cachant ses yeux,\r
+avait l'air de ne rien voir et laissait faire. Il y avait à Faverolles,\r
+pas loin de la chaumière Valjean, de l'autre côté de la ruelle, une\r
+fermière appelée Marie-Claude; les enfants Valjean, habituellement\r
+affamés, allaient quelquefois emprunter au nom de leur mère une pinte de\r
+lait à Marie-Claude, qu'ils buvaient derrière une haie ou dans quelque\r
+coin d'allée, s'arrachant le pot, et si hâtivement que les petites\r
+filles s'en répandaient sur leur tablier et dans leur goulotte. La mère,\r
+si elle eût su cette maraude, eût sévèrement corrigé les délinquants.\r
+Jean Valjean, brusque et bougon, payait en arrière de la mère la pinte\r
+de lait à Marie-Claude, et les enfants n'étaient pas punis.\r
+\r
+Il gagnait dans la saison de l'émondage vingt-quatre sous par jour, puis\r
+il se louait comme moissonneur, comme manoeuvre, comme garçon de ferme\r
+bouvier, comme homme de peine. Il faisait ce qu'il pouvait. Sa soeur\r
+travaillait de son côté, mais que faire avec sept petits enfants?\r
+C'était un triste groupe que la misère enveloppa et étreignit peu à peu.\r
+Il arriva qu'un hiver fut rude. Jean n'eut pas d'ouvrage. La famille\r
+n'eut pas de pain. Pas de pain. À la lettre. Sept enfants! Un dimanche\r
+soir, Maubert Isabeau, boulanger sur la place de l'Église, à Faverolles,\r
+se disposait à se coucher, lorsqu'il entendit un coup violent dans la\r
+devanture grillée et vitrée de sa boutique. Il arriva à temps pour voir\r
+un bras passé à travers un trou fait d'un coup de poing dans la grille\r
+et dans la vitre. Le bras saisit un pain et l'emporta. Isabeau sortit en\r
+hâte; le voleur s'enfuyait à toutes jambes; Isabeau courut après lui et\r
+l'arrêta. Le voleur avait jeté le pain, mais il avait encore le bras\r
+ensanglanté. C'était Jean Valjean.\r
+\r
+Ceci se passait en 1795. Jean Valjean fut traduit devant les tribunaux\r
+du temps «pour vol avec effraction la nuit dans une maison habitée». Il\r
+avait un fusil dont il se servait mieux que tireur au monde, il était\r
+quelque peu braconnier; ce qui lui nuisit. Il y a contre les braconniers\r
+un préjugé légitime. Le braconnier, de même que le contrebandier, côtoie\r
+de fort près le brigand. Pourtant, disons-le en passant, il y a encore\r
+un abîme entre ces races d'hommes et le hideux assassin des villes. Le\r
+braconnier vit dans la forêt; le contrebandier vit dans la montagne ou\r
+sur la mer. Les villes font des hommes féroces parce qu'elles font des\r
+hommes corrompus. La montagne, la mer, la forêt, font des hommes\r
+sauvages. Elles développent le côté farouche, mais souvent sans détruire\r
+le côté humain.\r
+\r
+Jean Valjean fut déclaré coupable. Les termes du code étaient formels.\r
+Il y a dans notre civilisation des heures redoutables; ce sont les\r
+moments où la pénalité prononce un naufrage. Quelle minute funèbre que\r
+celle où la société s'éloigne et consomme l'irréparable abandon d'un\r
+être pensant! Jean Valjean fut condamné à cinq ans de galères.\r
+\r
+Le 22 avril 1796, on cria dans Paris la victoire de Montenotte remportée\r
+par le général en chef de l'année d'Italie, que le message du Directoire\r
+aux Cinq-Cents, du 2 floréal an IV, appelle Buona-Parte; ce même jour\r
+une grande chaîne fut ferrée à Bicêtre. Jean Valjean fit partie de cette\r
+chaîne. Un ancien guichetier de la prison, qui a près de\r
+quatre-vingt-dix ans aujourd'hui, se souvient encore parfaitement de ce\r
+malheureux qui fut ferré à l'extrémité du quatrième cordon dans l'angle\r
+nord de la cour. Il était assis à terre comme tous les autres. Il\r
+paraissait ne rien comprendre à sa position, sinon qu'elle était\r
+horrible. Il est probable qu'il y démêlait aussi, à travers les vagues\r
+idées d'un pauvre homme ignorant de tout, quelque chose d'excessif.\r
+Pendant qu'on rivait à grands coups de marteau derrière sa tête le\r
+boulon de son carcan, il pleurait, les larmes l'étouffaient, elles\r
+l'empêchaient de parler, il parvenait seulement à dire de temps en\r
+temps: _J'étais émondeur à Faverolles_. Puis, tout en sanglotant, il\r
+élevait sa main droite et l'abaissait graduellement sept fois comme s'il\r
+touchait successivement sept têtes inégales, et par ce geste on devinait\r
+que la chose quelconque qu'il avait faite, il l'avait faite pour vêtir\r
+et nourrir sept petits enfants.\r
+\r
+Il partit pour Toulon. Il y arriva après un voyage de vingt-sept jours,\r
+sur une charrette, la chaîne au cou. À Toulon, il fut revêtu de la\r
+casaque rouge. Tout s'effaça de ce qui avait été sa vie, jusqu'à son\r
+nom; il ne fut même plus Jean Valjean; il fut le numéro 24601. Que\r
+devint la soeur? que devinrent les sept enfants? Qui est-ce qui s'occupe\r
+de cela? Que devient la poignée de feuilles du jeune arbre scié par le\r
+pied?\r
+\r
+C'est toujours la même histoire. Ces pauvres êtres vivants, ces\r
+créatures de Dieu, sans appui désormais, sans guide, sans asile, s'en\r
+allèrent au hasard, qui sait même? chacun de leur côté peut-être, et\r
+s'enfoncèrent peu à peu dans cette froide brume où s'engloutissent les\r
+destinées solitaires, moines ténèbres où disparaissent successivement\r
+tant de têtes infortunées dans la sombre marche du genre humain. Ils\r
+quittèrent le pays. Le clocher de ce qui avait été leur village les\r
+oublia; la borne de ce qui avait été leur champ les oublia; après\r
+quelques années de séjour au bagne, Jean Valjean lui-même les oublia.\r
+Dans ce coeur où il y avait eu une plaie, il y eut une cicatrice. Voilà\r
+tout. À peine, pendant tout le temps qu'il passa à Toulon, entendit-il\r
+parler une seule fois de sa soeur. C'était, je crois, vers la fin de la\r
+quatrième année de sa captivité. Je ne sais plus par quelle voie ce\r
+renseignement lui parvint. Quelqu'un, qui les avait connus au pays,\r
+avait vu sa soeur. Elle était à Paris. Elle habitait une pauvre rue près\r
+de Saint-Sulpice, la rue du Geindre. Elle n'avait plus avec elle qu'un\r
+enfant, un petit garçon, le dernier. Où étaient les six autres? Elle ne\r
+le savait peut-être pas elle-même. Tous les matins elle allait à une\r
+imprimerie rue du Sabot, n° 3, où elle était plieuse et brocheuse. Il\r
+fallait être là à six heures du matin, bien avant le jour l'hiver. Dans\r
+la maison de l'imprimerie il y avait une école, elle menait à cette\r
+école son petit garçon qui avait sept ans. Seulement, comme elle entrait\r
+à l'imprimerie à six heures et que l'école n'ouvrait qu'à sept, il\r
+fallait que l'enfant attendît, dans la cour, que l'école ouvrit, une\r
+heure; l'hiver, une heure de nuit, en plein air. On ne voulait pas que\r
+l'enfant entrât dans l'imprimerie, parce qu'il gênait, disait-on. Les\r
+ouvriers voyaient le matin en passant ce pauvre petit être assis sur le\r
+pavé, tombant de sommeil, et souvent endormi dans l'ombre, accroupi et\r
+plié sur son panier. Quand il pleuvait, une vieille femme, la portière,\r
+en avait pitié; elle le recueillait dans son bouge où il n'y avait qu'un\r
+grabat, un rouet et deux chaises de bois, et le petit dormait là dans un\r
+coin, se serrant contre le chat pour avoir moins froid. À sept heures,\r
+l'école ouvrait et il y entrait. Voilà ce qu'on dit à Jean Valjean. On\r
+l'en entretint un jour, ce fut un moment, un éclair, comme une fenêtre\r
+brusquement ouverte sur la destinée de ces êtres qu'il avait aimés, puis\r
+tout se referma; il n'en entendit plus parler, et ce fut pour jamais.\r
+Plus rien n'arriva d'eux à lui; jamais il ne les revit, jamais il ne les\r
+rencontra, et, dans la suite de cette douloureuse histoire, on ne les\r
+retrouvera plus.\r
+\r
+Vers la fin de cette quatrième année, le tour d'évasion de Jean Valjean\r
+arriva. Ses camarades l'aidèrent comme cela se fait dans ce triste lieu.\r
+Il s'évada. Il erra deux jours en liberté dans les champs; si c'est être\r
+libre que d'être traqué; de tourner la tête à chaque instant; de\r
+tressaillir au moindre bruit; d'avoir peur de tout, du toit qui fume, de\r
+l'homme qui passe, du chien qui aboie, du cheval qui galope, de l'heure\r
+qui sonne, du jour parce qu'on voit, de la nuit parce qu'on ne voit pas,\r
+de la route, du sentier, du buisson, du sommeil. Le soir du second jour,\r
+il fut repris. Il n'avait ni mangé ni dormi depuis trente-six heures. Le\r
+tribunal maritime le condamna pour ce délit à une prolongation de trois\r
+ans, ce qui lui fit huit ans. La sixième année, ce fut encore son tour\r
+de s'évader; il en usa, mais il ne put consommer sa fuite. Il avait\r
+manqué à l'appel. On tira le coup de canon, et à la nuit les gens de\r
+ronde le trouvèrent caché sous la quille d'un vaisseau en construction;\r
+il résista aux gardes-chiourme qui le saisirent. Évasion et rébellion.\r
+Ce fait prévu par le code spécial fut puni d'une aggravation de cinq\r
+ans, dont deux ans de double chaîne. Treize ans. La dixième année, son\r
+tour revint, il en profita encore. Il ne réussit pas mieux. Trois ans\r
+pour cette nouvelle tentative. Seize ans. Enfin, ce fut, je crois,\r
+pendant la treizième année qu'il essaya une dernière fois et ne réussit\r
+qu'à se faire reprendre après quatre heures d'absence. Trois ans pour\r
+ces quatre heures. Dix-neuf ans. En octobre 1815 il fut libéré; il était\r
+entré là en 1796 pour avoir cassé un carreau et pris un pain.\r
+\r
+Place pour une courte parenthèse. C'est la seconde fois que, dans ses\r
+études sur la question pénale et sur la damnation par la loi, l'auteur\r
+de ce livre rencontre le vol d'un pain, comme point de départ du\r
+désastre d'une destinée. Claude Gueux avait volé un pain; Jean Valjean\r
+avait volé un pain. Une statistique anglaise constate qu'à Londres\r
+quatre vols sur cinq ont pour cause immédiate la faim.\r
+\r
+Jean Valjean était entré au bagne sanglotant et frémissant; il en sortit\r
+impassible. Il y était entré désespéré; il en sortit sombre.\r
+\r
+Que s'était-il passé dans cette âme?\r
+\r
+\r
+\r
+\r
+Chapitre VII\r
+\r
+Le dedans du désespoir\r
+\r
+\r
+Essayons de le dire.\r
+\r
+Il faut bien que la société regarde ces choses puisque c'est elle qui\r
+les fait.\r
+\r
+C'était, nous l'avons dit, un ignorant; mais ce n'était pas un imbécile.\r
+La lumière naturelle était allumée en lui. Le malheur, qui a aussi sa\r
+clarté, augmenta le peu de jour qu'il y avait dans cet esprit. Sous le\r
+bâton, sous la chaîne, au cachot, à la fatigue, sous l'ardent soleil du\r
+bagne, sur le lit de planches des forçats, il se replia en sa conscience\r
+et réfléchit.\r
+\r
+Il se constitua tribunal.\r
+\r
+Il commença par se juger lui-même.\r
+\r
+Il reconnut qu'il n'était pas un innocent injustement puni. Il s'avoua\r
+qu'il avait commis une action extrême et blâmable; qu'on ne lui eût\r
+peut-être pas refusé ce pain s'il l'avait demandé; que dans tous les cas\r
+il eût mieux valu l'attendre, soit de la pitié, soit du travail; que ce\r
+n'est pas tout à fait une raison sans réplique de dire: peut-on attendre\r
+quand on a faim? que d'abord il est très rare qu'on meure littéralement\r
+de faim; ensuite que, malheureusement ou heureusement, l'homme est ainsi\r
+fait qu'il peut souffrir longtemps et beaucoup, moralement et\r
+physiquement, sans mourir; qu'il fallait donc de la patience; que cela\r
+eût mieux valu même pour ces pauvres petits enfants; que c'était un acte\r
+de folie, à lui, malheureux homme chétif, de prendre violemment au\r
+collet la société tout entière et de se figurer qu'on sort de la misère\r
+par le vol; que c'était, dans tous les cas, une mauvaise porte pour\r
+sortir de la misère que celle par où l'on entre dans l'infamie; enfin\r
+qu'il avait eu tort.\r
+\r
+Puis il se demanda:\r
+\r
+S'il était le seul qui avait eu tort dans sa fatale histoire? Si d'abord\r
+ce n'était pas une chose grave qu'il eût, lui travailleur, manqué de\r
+travail, lui laborieux, manqué de pain. Si, ensuite, la faute commise et\r
+avouée, le châtiment n'avait pas été féroce et outré. S'il n'y avait pas\r
+plus d'abus de la part de la loi dans la peine qu'il n'y avait eu d'abus\r
+de la part du coupable dans la faute. S'il n'y avait pas excès de poids\r
+dans un des plateaux de la balance, celui où est l'expiation. Si la\r
+surcharge de la peine n'était point l'effacement du délit, et n'arrivait\r
+pas à ce résultat: de retourner la situation, de remplacer la faute du\r
+délinquant par la faute de la répression, de faire du coupable la\r
+victime et du débiteur le créancier, et de mettre définitivement le\r
+droit du côté de celui-là même qui l'avait violé. Si cette peine,\r
+compliquée des aggravations successives pour les tentatives d'évasion,\r
+ne finissait pas par être une sorte d'attentat du plus fort sur le plus\r
+faible, un crime de la société sur l'individu, un crime qui recommençait\r
+tous les jours, un crime qui durait dix-neuf ans.\r
+\r
+Il se demanda si la société humaine pouvait avoir le droit de faire\r
+également subir à ses membres, dans un cas son imprévoyance\r
+déraisonnable, et dans l'autre cas sa prévoyance impitoyable, et de\r
+saisir à jamais un pauvre homme entre un défaut et un excès, défaut de\r
+travail, excès de châtiment. S'il n'était pas exorbitant que la société\r
+traitât ainsi précisément ses membres les plus mal dotés dans la\r
+répartition de biens que fait le hasard, et par conséquent les plus\r
+dignes de ménagements.\r
+\r
+Ces questions faites et résolues, il jugea la société et la condamna.\r
+\r
+Il la condamna sans haine.\r
+\r
+Il la fit responsable du sort qu'il subissait, et se dit qu'il\r
+n'hésiterait peut-être pas à lui en demander compte un jour. Il se\r
+déclara à lui-même qu'il n'y avait pas équilibre entre le dommage qu'il\r
+avait causé et le dommage qu'on lui causait; il conclut enfin que son\r
+châtiment n'était pas, à la vérité, une injustice, mais qu'à coup sûr\r
+c'était une iniquité.\r
+\r
+La colère peut être folle et absurde; on peut être irrité à tort; on\r
+n'est indigné que lorsqu'on a raison au fond par quelque côté. Jean\r
+Valjean se sentait indigné. Et puis, la société humaine ne lui avait\r
+fait que du mal. Jamais il n'avait vu d'elle que ce visage courroucé\r
+qu'elle appelle sa justice et qu'elle montre à ceux qu'elle frappe. Les\r
+hommes ne l'avaient touché que pour le meurtrir. Tout contact avec eux\r
+lui avait été un coup. Jamais, depuis son enfance, depuis sa mère,\r
+depuis sa soeur, jamais il n'avait rencontré une parole amie et un\r
+regard bienveillant. De souffrance en souffrance il arriva peu à peu à\r
+cette conviction que la vie était une guerre; et que dans cette guerre\r
+il était le vaincu. Il n'avait d'autre arme que sa haine. Il résolut de\r
+l'aiguiser au bagne et de l'emporter en s'en allant.\r
+\r
+Il y avait à Toulon une école pour la chiourme tenue par des frères\r
+ignorantins où l'on enseignait le plus nécessaire à ceux de ces\r
+malheureux qui avaient de la bonne volonté. Il fut du nombre des hommes\r
+de bonne volonté. Il alla à l'école à quarante ans, et apprit à lire, à\r
+écrire, à compter. Il sentit que fortifier son intelligence, c'était\r
+fortifier sa haine. Dans certains cas, l'instruction et la lumière\r
+peuvent servir de rallonge au mal.\r
+\r
+Cela est triste à dire, après avoir jugé la société qui avait fait son\r
+malheur, il jugea la providence qui avait fait la société.\r
+\r
+Il la condamna aussi.\r
+\r
+Ainsi, pendant ces dix-neuf ans de torture et d'esclavage, cette âme\r
+monta et tomba en même temps. Il y entra de la lumière d'un côté et des\r
+ténèbres de l'autre.\r
+\r
+Jean Valjean n'était pas, on l'a vu, d'une nature mauvaise. Il était\r
+encore bon lorsqu'il arriva au bagne. Il y condamna la société et sentit\r
+qu'il devenait méchant, il y condamna la providence et sentit qu'il\r
+devenait impie.\r
+\r
+Ici il est difficile de ne pas méditer un instant.\r
+\r
+La nature humaine se transforme-t-elle ainsi de fond en comble et tout à\r
+fait? L'homme créé bon par Dieu peut-il être fait méchant par l'homme?\r
+L'âme peut-elle être refaite tout d'une pièce par la destinée, et\r
+devenir mauvaise, la destinée étant mauvaise? Le coeur peut-il devenir\r
+difforme et contracter des laideurs et des infirmités incurables sous la\r
+pression d'un malheur disproportionné, comme la colonne vertébrale sous\r
+une voûte trop basse? N'y a-t-il pas dans toute âme humaine, n'y\r
+avait-il pas dans l'âme de Jean Valjean en particulier, une première\r
+étincelle, un élément divin, incorruptible dans ce monde, immortel dans\r
+l'autre, que le bien peut développer, attiser, allumer, enflammer et\r
+faire rayonner splendidement, et que le mal ne peut jamais entièrement\r
+éteindre?\r
+\r
+Questions graves et obscures, à la dernière desquelles tout\r
+physiologiste eût probablement répondu non, et sans hésiter, s'il eût vu\r
+à Toulon, aux heures de repos qui étaient pour Jean Valjean des heures\r
+de rêverie, assis, les bras croisés, sur la barre de quelque cabestan,\r
+le bout de sa chaîne enfoncé dans sa poche pour l'empêcher de traîner,\r
+ce galérien morne, sérieux, silencieux et pensif, paria des lois qui\r
+regardait l'homme avec colère, damné de la civilisation qui regardait le\r
+ciel avec sévérité.\r
+\r
+Certes, et nous ne voulons pas le dissimuler, le physiologiste\r
+observateur eût vu là une misère irrémédiable, il eût plaint peut-être\r
+ce malade du fait de la loi, mais il n'eût pas même essayé de\r
+traitement; il eût détourné le regard des cavernes qu'il aurait\r
+entrevues dans cette âme; et, comme Dante de la porte de l'enfer, il eût\r
+effacé de cette existence le mot que le doigt de Dieu écrit pourtant sur\r
+le front de tout homme: _Espérance_!\r
+\r
+Cet état de son âme que nous avons tenté d'analyser était-il aussi\r
+parfaitement clair pour Jean Valjean que nous avons essayé de le rendre\r
+pour ceux qui nous lisent? Jean Valjean voyait-il distinctement, après\r
+leur formation, et avait-il vu distinctement, à mesure qu'ils se\r
+formaient, tous les éléments dont se composait sa misère morale? Cet\r
+homme rude et illettré s'était-il bien nettement rendu compte de la\r
+succession d'idées par laquelle il était, degré à degré, monté et\r
+descendu jusqu'aux lugubres aspects qui étaient depuis tant d'années\r
+déjà l'horizon intérieur de son esprit? Avait-il bien conscience de tout\r
+ce qui s'était passé en lui et de tout ce qui s'y remuait? C'est ce que\r
+nous n'oserions dire; c'est même ce que nous ne croyons pas. Il y avait\r
+trop d'ignorance dans Jean Valjean pour que, même après tant de malheur,\r
+il n'y restât pas beaucoup de vague. Par moments il ne savait pas même\r
+bien au juste ce qu'il éprouvait. Jean Valjean était dans les ténèbres;\r
+il souffrait dans les ténèbres; il haïssait dans les ténèbres; on eût pu\r
+dire qu'il haïssait devant lui. Il vivait habituellement dans cette\r
+ombre, tâtonnant comme un aveugle et comme un rêveur. Seulement, par\r
+intervalles, il lui venait tout à coup, de lui-même ou du dehors, une\r
+secousse de colère, un surcroît de souffrance, un pâle et rapide éclair\r
+qui illuminait toute son âme, et faisait brusquement apparaître partout\r
+autour de lui, en avant et en arrière, aux lueurs d'une lumière\r
+affreuse, les hideux précipices et les sombres perspectives de sa\r
+destinée.\r
+\r
+L'éclair passé, la nuit retombait, et où était-il? il ne le savait plus.\r
+\r
+Le propre des peines de cette nature, dans lesquelles domine ce qui est\r
+impitoyable, c'est-à-dire ce qui est abrutissant, c'est de transformer\r
+peu à peu, par une sorte de transfiguration stupide, un homme en une\r
+bête fauve. Quelquefois en une bête féroce. Les tentatives d'évasion de\r
+Jean Valjean, successives et obstinées, suffiraient à prouver cet\r
+étrange travail fait par la loi sur l'âme humaine. Jean Valjean eût\r
+renouvelé ces tentatives, si parfaitement inutiles et folles, autant de\r
+fois que l'occasion s'en fût présentée, sans songer un instant au\r
+résultat, ni aux expériences déjà faites. Il s'échappait impétueusement\r
+comme le loup qui trouve la cage ouverte. L'instinct lui disait:\r
+sauve-toi! Le raisonnement lui eût dit: reste! Mais, devant une\r
+tentation si violente, le raisonnement avait disparu; il n'y avait plus\r
+que l'instinct. La bête seule agissait. Quand il était repris, les\r
+nouvelles sévérités qu'on lui infligeait ne servaient qu'à l'effarer\r
+davantage.\r
+\r
+Un détail que nous ne devons pas omettre, c'est qu'il était d'une force\r
+physique dont n'approchait pas un des habitants du bagne. À la fatigue,\r
+pour filer un câble, pour virer un cabestan, Jean Valjean valait quatre\r
+hommes. Il soulevait et soutenait parfois d'énormes poids sur son dos,\r
+et remplaçait dans l'occasion cet instrument qu'on appelle cric et qu'on\r
+appelait jadis orgueil, d'où a pris nom, soit dit en passant, la rue\r
+Montorgueil près des halles de Paris. Ses camarades l'avaient surnommé\r
+Jean-le-Cric. Une fois, comme on réparait le balcon de l'hôtel de ville\r
+de Toulon, une des admirables cariatides de Puget qui soutiennent ce\r
+balcon se descella et faillit tomber. Jean Valjean, qui se trouvait là,\r
+soutint de l'épaule la cariatide et donna le temps aux ouvriers\r
+d'arriver.\r
+\r
+Sa souplesse dépassait encore sa vigueur. Certains forçats, rêveurs\r
+perpétuels d'évasions, finissent par faire de la force et de l'adresse\r
+combinées une véritable science. C'est la science des muscles. Toute une\r
+statique mystérieuse est quotidiennement pratiquée par les prisonniers,\r
+ces éternels envieux des mouches et des oiseaux. Gravir une verticale,\r
+et trouver des points d'appui là où l'on voit à peine une saillie, était\r
+un jeu pour Jean Valjean. Étant donné un angle de mur, avec la tension\r
+de son dos et de ses jarrets, avec ses coudes et ses talons emboîtés\r
+dans les aspérités de la pierre, il se hissait comme magiquement à un\r
+troisième étage. Quelquefois il montait ainsi jusqu'au toit du bagne.\r
+\r
+Il parlait peu. Il ne riait pas. Il fallait quelque émotion extrême pour\r
+lui arracher, une ou deux fois l'an, ce lugubre rire du forçat qui est\r
+comme un écho du rire du démon. À le voir, il semblait occupé à regarder\r
+continuellement quelque chose de terrible.\r
+\r
+Il était absorbé en effet.\r
+\r
+À travers les perceptions maladives d'une nature incomplète et d'une\r
+intelligence accablée, il sentait confusément qu'une chose monstrueuse\r
+était sur lui. Dans cette pénombre obscure et blafarde où il rampait,\r
+chaque fois qu'il tournait le cou et qu'il essayait d'élever son regard,\r
+il voyait, avec une terreur mêlée de rage, s'échafauder, s'étager et\r
+monter à perte de vue au-dessus de lui, avec des escarpements horribles,\r
+une sorte d'entassement effrayant de choses, de lois, de préjugés,\r
+d'hommes et de faits, dont les contours lui échappaient, dont la masse\r
+l'épouvantait, et qui n'était autre chose que cette prodigieuse pyramide\r
+que nous appelons la civilisation. Il distinguait çà et là dans cet\r
+ensemble fourmillant et difforme, tantôt près de lui, tantôt loin et sur\r
+des plateaux inaccessibles, quelque groupe, quelque détail vivement\r
+éclairé, ici l'argousin et son bâton, ici le gendarme et son sabre,\r
+là-bas l'archevêque mitré, tout en haut, dans une sorte de soleil,\r
+l'empereur couronné et éblouissant. Il lui semblait que ces splendeurs\r
+lointaines, loin de dissiper sa nuit, la rendaient plus funèbre et plus\r
+noire. Tout cela, lois, préjugés, faits, hommes, choses, allait et\r
+venait au-dessus de lui, selon le mouvement compliqué et mystérieux que\r
+Dieu imprime à la civilisation, marchant sur lui et l'écrasant avec je\r
+ne sais quoi de paisible dans la cruauté et d'inexorable dans\r
+l'indifférence. Âmes tombées au fond de l'infortune possible, malheureux\r
+hommes perdus au plus bas de ces limbes où l'on ne regarde plus, les\r
+réprouvés de la loi sentent peser de tout son poids sur leur tête cette\r
+société humaine, si formidable pour qui est dehors, si effroyable pour\r
+qui est dessous.\r
+\r
+Dans cette situation, Jean Valjean songeait, et quelle pouvait être la\r
+nature de sa rêverie?\r
+\r
+Si le grain de mil sous la meule avait des pensées, il penserait sans\r
+doute ce que pensait Jean Valjean.\r
+\r
+Toutes ces choses, réalités pleines de spectres, fantasmagories pleines\r
+de réalités, avaient fini par lui créer une sorte d'état intérieur\r
+presque inexprimable.\r
+\r
+Par moments, au milieu de son travail du bagne, il s'arrêtait. Il se\r
+mettait à penser. Sa raison, à la fois plus mûre et plus troublée\r
+qu'autrefois, se révoltait. Tout ce qui lui était arrivé lui paraissait\r
+absurde; tout ce qui l'entourait lui paraissait impossible. Il se\r
+disait: c'est un rêve. Il regardait l'argousin debout à quelques pas de\r
+lui; l'argousin lui semblait un fantôme; tout à coup le fantôme lui\r
+donnait un coup de bâton.\r
+\r
+La nature visible existait à peine pour lui. Il serait presque vrai de\r
+dire qu'il n'y avait point pour Jean Valjean de soleil, ni de beaux\r
+jours d'été, ni de ciel rayonnant, ni de fraîches aubes d'avril. Je ne\r
+sais quel jour de soupirail éclairait habituellement son âme.\r
+\r
+Pour résumer, en terminant, ce qui peut être résumé et traduit en\r
+résultats positifs dans tout ce que nous venons d'indiquer, nous nous\r
+bornerons à constater qu'en dix-neuf ans, Jean Valjean, l'inoffensif\r
+émondeur de Faverolles, le redoutable galérien de Toulon, était devenu\r
+capable, grâce à la manière dont le bagne l'avait façonné, de deux\r
+espèces de mauvaises actions: premièrement, d'une mauvaise action\r
+rapide, irréfléchie, pleine d'étourdissement, toute d'instinct, sorte de\r
+représaille pour le mal souffert; deuxièmement, d'une mauvaise action\r
+grave, sérieuse, débattue en conscience et méditée avec les idées\r
+fausses que peut donner un pareil malheur. Ses préméditations passaient\r
+par les trois phases successives que les natures d'une certaine trempe\r
+peuvent seules parcourir, raisonnement, volonté, obstination. Il avait\r
+pour mobiles l'indignation habituelle, l'amertume de l'âme, le profond\r
+sentiment des iniquités subies, la réaction, même contre les bons, les\r
+innocents et les justes, s'il y en a. Le point de départ comme le point\r
+d'arrivée de toutes ses pensées était la haine de la loi humaine; cette\r
+haine qui, si elle n'est arrêtée dans son développement par quelque\r
+incident providentiel, devient, dans un temps donné, la haine de la\r
+société, puis la haine du genre humain, puis la haine de la création, et\r
+se traduit par un vague et incessant et brutal désir de nuire, n'importe\r
+à qui, à un être vivant quelconque. Comme on voit, ce n'était pas sans\r
+raison que le passeport qualifiait Jean Valjean d'_homme très\r
+dangereux_.\r
+\r
+D'année en année, cette âme s'était desséchée de plus en plus,\r
+lentement, mais fatalement. À coeur sec, oeil sec. À sa sortie du bagne,\r
+il y avait dix-neuf ans qu'il n'avait versé une larme.\r
+\r
+\r
+\r
+\r
+Chapitre VIII\r
+\r
+L'onde et l'ombre\r
+\r
+\r
+Un homme à la mer!\r
+\r
+Qu'importe! le navire ne s'arrête pas. Le vent souffle, ce sombre\r
+navire-là a une route qu'il est forcé de continuer. Il passe.\r
+\r
+L'homme disparaît, puis reparaît, il plonge et remonte à la surface, il\r
+appelle, il tend les bras, on ne l'entend pas; le navire, frissonnant\r
+sous l'ouragan, est tout à sa manoeuvre, les matelots et les passagers\r
+ne voient même plus l'homme submergé; sa misérable tête n'est qu'un\r
+point dans l'énormité des vagues. Il jette des cris désespérés dans les\r
+profondeurs. Quel spectre que cette voile qui s'en va! Il la regarde, il\r
+la regarde frénétiquement. Elle s'éloigne, elle blêmit, elle décroît. Il\r
+était là tout à l'heure, il était de l'équipage, il allait et venait sur\r
+le pont avec les autres, il avait sa part de respiration et de soleil,\r
+il était un vivant. Maintenant, que s'est-il donc passé? Il a glissé, il\r
+est tombé, c'est fini.\r
+\r
+Il est dans l'eau monstrueuse. Il n'a plus sous les pieds que de la\r
+fuite et de l'écroulement. Les flots déchirés et déchiquetés par le vent\r
+l'environnent hideusement, les roulis de l'abîme l'emportent, tous les\r
+haillons de l'eau s'agitent autour de sa tête, une populace de vagues\r
+crache sur lui, de confuses ouvertures le dévorent à demi; chaque fois\r
+qu'il enfonce, il entrevoit des précipices pleins de nuit; d'affreuses\r
+végétations inconnues le saisissent, lui nouent les pieds, le tirent à\r
+elles; il sent qu'il devient abîme, il fait partie de l'écume, les flots\r
+se le jettent de l'un à l'autre, il boit l'amertume, l'océan lâche\r
+s'acharne à le noyer, l'énormité joue avec son agonie. Il semble que\r
+toute cette eau soit de la haine.\r
+\r
+Il lutte pourtant, il essaie de se défendre, il essaie de se soutenir,\r
+il fait effort, il nage. Lui, cette pauvre force tout de suite épuisée,\r
+il combat l'inépuisable.\r
+\r
+Où donc est le navire? Là-bas. À peine visible dans les pâles ténèbres\r
+de l'horizon.\r
+\r
+Les rafales soufflent; toutes les écumes l'accablent. Il lève les yeux\r
+et ne voit que les lividités des nuages. Il assiste, agonisant, à\r
+l'immense démence de la mer. Il est supplicié par cette folie. Il entend\r
+des bruits étrangers à l'homme qui semblent venir d'au delà de la terre\r
+et d'on ne sait quel dehors effrayant.\r
+\r
+Il y a des oiseaux dans les nuées, de même qu'il y a des anges au-dessus\r
+des détresses humaines, mais que peuvent-ils pour lui? Cela vole, chante\r
+et plane, et lui, il râle.\r
+\r
+Il se sent enseveli à la fois par ces deux infinis, l'océan et le ciel;\r
+l'un est une tombe, l'autre est un linceul.\r
+\r
+La nuit descend, voilà des heures qu'il nage, ses forces sont à bout; ce\r
+navire, cette chose lointaine où il y avait des hommes, s'est effacé; il\r
+est seul dans le formidable gouffre crépusculaire, il enfonce, il se\r
+roidit, il se tord, il sent au-dessous de lui les vagues monstres de\r
+l'invisible; il appelle.\r
+\r
+Il n'y a plus d'hommes. Où est Dieu?\r
+\r
+Il appelle. Quelqu'un! quelqu'un! Il appelle toujours.\r
+\r
+Rien à l'horizon. Rien au ciel.\r
+\r
+Il implore l'étendue, la vague, l'algue, l'écueil; cela est sourd. Il\r
+supplie la tempête; la tempête imperturbable n'obéit qu'à l'infini.\r
+\r
+Autour de lui, l'obscurité, la brume, la solitude, le tumulte orageux et\r
+inconscient, le plissement indéfini des eaux farouches. En lui l'horreur\r
+et la fatigue. Sous lui la chute. Pas de point d'appui. Il songe aux\r
+aventures ténébreuses du cadavre dans l'ombre illimitée. Le froid sans\r
+fond le paralyse. Ses mains se crispent et se ferment et prennent du\r
+néant. Vents, nuées, tourbillons, souffles, étoiles inutiles! Que faire?\r
+Le désespéré s'abandonne, qui est las prend le parti de mourir, il se\r
+laisse faire, il se laisse aller, il lâche prise, et le voilà qui roule\r
+à jamais dans les profondeurs lugubres de l'engloutissement.\r
+\r
+Ô marche implacable des sociétés humaines! Pertes d'hommes et d'âmes\r
+chemin faisant! Océan où tombe tout ce que laisse tomber la loi!\r
+Disparition sinistre du secours! ô mort morale!\r
+\r
+La mer, c'est l'inexorable nuit sociale où la pénalité jette ses damnés.\r
+La mer, c'est l'immense misère.\r
+\r
+L'âme, à vau-l'eau dans ce gouffre, peut devenir un cadavre. Qui la\r
+ressuscitera?\r

+\r
+Nouveaux griefs\r
+\r
+\r
+Quand vint l'heure de la sortie du bagne, quand Jean Valjean entendit à\r
+son oreille ce mot étrange: _tu es libre_! le moment fut invraisemblable\r
+et inouï, un rayon de vive lumière, un rayon de la vraie lumière des\r
+vivants pénétra subitement en lui. Mais ce rayon ne tarda point à pâlir.\r
+Jean Valjean avait été ébloui de l'idée de la liberté. Il avait cru à\r
+une vie nouvelle. Il vit bien vite ce que c'était qu'une liberté à\r
+laquelle on donne un passeport jaune.\r
+\r
+Et autour de cela bien des amertumes. Il avait calculé que sa masse,\r
+pendant son séjour au bagne, aurait dû s'élever à cent soixante et onze\r
+francs. Il est juste d'ajouter qu'il avait oublié de faire entrer dans\r
+ses calculs le repos forcé des dimanches et fêtes qui, pour dix-neuf\r
+ans, entraînait une diminution de vingt-quatre francs environ. Quoi\r
+qu'il en fût, cette masse avait été réduite, par diverses retenues\r
+locales, à la somme de cent neuf francs quinze sous, qui lui avait été\r
+comptée à sa sortie.\r
+\r
+Il n'y avait rien compris, et se croyait lésé. Disons le mot, volé.\r
+\r
+Le lendemain de sa libération, à Grasse, il vit devant la porte d'une\r
+distillerie de fleurs d'oranger des hommes qui déchargeaient des\r
+ballots. Il offrit ses services. La besogne pressait, on les accepta. Il\r
+se mit à l'ouvrage. Il était intelligent, robuste et adroit; il faisait\r
+de son mieux; le maître paraissait content. Pendant qu'il travaillait,\r
+un gendarme passa, le remarqua, et lui demanda ses papiers. Il fallut\r
+montrer le passeport jaune. Cela fait, Jean Valjean reprit son travail.\r
+Un peu auparavant, il avait questionné l'un des ouvriers sur ce qu'ils\r
+gagnaient à cette besogne par jour; on lui avait répondu: _trente sous_.\r
+Le soir venu, comme il était forcé de repartir le lendemain matin, il se\r
+présenta devant le maître de la distillerie et le pria de le payer. Le\r
+maître ne proféra pas une parole, et lui remit vingt-cinq sous. Il\r
+réclama. On lui répondit: cela est assez bon pour toi. Il insista. Le\r
+maître le regarda entre les deux yeux et lui dit: _Gare le bloc_.\r
+\r
+Là encore il se considéra comme volé.\r
+\r
+La société, l'état, en lui diminuant sa masse, l'avait volé en grand.\r
+Maintenant, c'était le tour de l'individu qui le volait en petit.\r
+\r
+Libération n'est pas délivrance. On sort du bagne, mais non de la\r
+condamnation. Voilà ce qui lui était arrivé à Grasse. On a vu de quelle\r
+façon il avait été accueilli à Digne.\r
+\r

+\r
+\r
+Chapitre X\r
+\r
+L'homme réveillé\r
+\r
+\r
+Donc, comme deux heures du matin sonnaient à l'horloge de la cathédrale,\r
+Jean Valjean se réveilla.\r
+\r
+Ce qui le réveilla, c'est que le lit était trop bon. Il y avait vingt\r
+ans bientôt qu'il n'avait couché dans un lit, et quoiqu'il ne se fût pas\r
+déshabillé, la sensation était trop nouvelle pour ne pas troubler son\r
+sommeil.\r
+\r
+Il avait dormi plus de quatre heures. Sa fatigue était passée. Il était\r
+accoutumé à ne pas donner beaucoup d'heures au repos.\r
+\r
+Il ouvrit les yeux et regarda un moment dans l'obscurité autour de lui,\r
+puis il les referma pour se rendormir.\r
+\r
+Quand beaucoup de sensations diverses ont agité la journée, quand des\r
+choses préoccupent l'esprit, on s'endort, mais on ne se rendort pas. Le\r
+sommeil vient plus aisément qu'il ne revient. C'est ce qui arriva à Jean\r
+Valjean. Il ne put se rendormir, et il se mit à penser.\r
+\r
+Il était dans un de ces moments où les idées qu'on a dans l'esprit sont\r
+troubles. Il avait une sorte de va-et-vient obscur dans le cerveau. Ses\r
+souvenirs anciens et ses souvenirs immédiats y flottaient pêle-mêle et\r
+s'y croisaient confusément, perdant leurs formes, se grossissant\r
+démesurément, puis disparaissant tout à coup comme dans une eau fangeuse\r
+et agitée. Beaucoup de pensées lui venaient, mais il y en avait une qui\r
+se représentait continuellement et qui chassait toutes les autres. Cette\r
+pensée, nous allons la dire tout de suite:--Il avait remarqué les six\r
+couverts d'argent et la grande cuiller que madame Magloire avait posés\r
+sur la table.\r
+\r
+Ces six couverts d'argent l'obsédaient.--Ils étaient là.--À quelques\r
+pas.--À l'instant où il avait traversé la chambre d'à côté pour venir\r
+dans celle où il était, la vieille servante les mettait dans un petit\r
+placard à la tête du lit.--Il avait bien remarqué ce placard.--À droite,\r
+en entrant par la salle à manger.--Ils étaient massifs.--Et de vieille\r
+argenterie.--Avec la grande cuiller, on en tirerait au moins deux cents\r
+francs.--Le double de ce qu'il avait gagné en dix-neuf ans.--Il est\r
+vrai qu'il eût gagné davantage si l'_administration_ ne l'avait pas\r
+_volé_.\r
+\r
+Son esprit oscilla toute une grande heure dans des fluctuations\r
+auxquelles se mêlait bien quelque lutte. Trois heures sonnèrent. Il\r
+rouvrit les yeux, se dressa brusquement sur son séant, étendit le bras\r
+et tâta son havresac qu'il avait jeté dans le coin de l'alcôve, puis il\r
+laissa pendre ses jambes et poser ses pieds à terre, et se trouva,\r
+presque sans savoir comment, assis sur son lit.\r
+\r
+Il resta un certain temps rêveur dans cette attitude qui eût eu quelque\r
+chose de sinistre pour quelqu'un qui l'eût aperçu ainsi dans cette\r
+ombre, seul éveillé dans la maison endormie. Tout à coup il se baissa,\r
+ôta ses souliers et les posa doucement sur la natte près du lit, puis il\r
+reprit sa posture de rêverie et redevint immobile.\r
+\r
+Au milieu de cette méditation hideuse, les idées que nous venons\r
+d'indiquer remuaient sans relâche son cerveau, entraient, sortaient,\r
+rentraient, faisaient sur lui une sorte de pesée; et puis il songeait\r
+aussi, sans savoir pourquoi, et avec cette obstination machinale de la\r
+rêverie, à un forçat nommé Brevet qu'il avait connu au bagne, et dont le\r
+pantalon n'était retenu que par une seule bretelle de coton tricoté. Le\r
+dessin en damier de cette bretelle lui revenait sans cesse à l'esprit.\r
+\r
+Il demeurait dans cette situation, et y fût peut-être resté indéfiniment\r
+jusqu'au lever du jour, si l'horloge n'eût sonné un coup--le quart ou la\r
+demie. Il sembla que ce coup lui eût dit: allons!\r
+\r
+Il se leva debout, hésita encore un moment, et écouta; tout se taisait\r
+dans la maison; alors il marcha droit et à petits pas vers la fenêtre\r
+qu'il entrevoyait. La nuit n'était pas très obscure; c'était une pleine\r
+lune sur laquelle couraient de larges nuées chassées par le vent. Cela\r
+faisait au dehors des alternatives d'ombre et de clarté, des éclipses,\r
+puis des éclaircies, et au dedans une sorte de crépuscule. Ce\r
+crépuscule, suffisant pour qu'on pût se guider, intermittent à cause des\r
+nuages, ressemblait à l'espèce de lividité qui tombe d'un soupirail de\r
+cave devant lequel vont et viennent des passants. Arrivé à la fenêtre,\r
+Jean Valjean l'examina. Elle était sans barreaux, donnait sur le jardin\r
+et n'était fermée, selon la mode du pays, que d'une petite clavette. Il\r
+l'ouvrit, mais, comme un air froid et vif entra brusquement dans la\r
+chambre, il la referma tout de suite. Il regarda le jardin de ce regard\r
+attentif qui étudie plus encore qu'il ne regarde. Le jardin était enclos\r
+d'un mur blanc assez bas, facile à escalader. Au fond, au-delà, il\r
+distingua des têtes d'arbres également espacées, ce qui indiquait que ce\r
+mur séparait le jardin d'une avenue ou d'une ruelle plantée.\r
+\r
+Ce coup d'oeil jeté, il fit le mouvement d'un homme déterminé, marcha à\r
+son alcôve, prit son havresac, l'ouvrit, le fouilla, en tira quelque\r
+chose qu'il posa sur le lit, mit ses souliers dans une des poches,\r
+referma le tout, chargea le sac sur ses épaules, se couvrit de sa\r
+casquette dont il baissa la visière sur ses yeux, chercha son bâton en\r
+tâtonnant, et l'alla poser dans l'angle de la fenêtre, puis revint au\r
+lit et saisit résolument l'objet qu'il y avait déposé. Cela ressemblait\r
+à une barre de fer courte, aiguisée comme un épieu à l'une de ses\r
+extrémités.\r
+\r
+Il eût été difficile de distinguer dans les ténèbres pour quel emploi\r
+avait pu être façonné ce morceau de fer. C'était peut-être un levier?\r
+C'était peut-être une massue?\r
+\r
+Au jour on eût pu reconnaître que ce n'était autre chose qu'un\r
+chandelier de mineur. On employait alors quelquefois les forçats à\r
+extraire de la roche des hautes collines qui environnent Toulon, et il\r
+n'était pas rare qu'ils eussent à leur disposition des outils de mineur.\r
+Les chandeliers des mineurs sont en fer massif, terminés à leur\r
+extrémité inférieure par une pointe au moyen de laquelle on les enfonce\r
+dans le rocher.\r
+\r
+Il prit ce chandelier dans sa main droite, et retenant son haleine,\r
+assourdissant son pas, il se dirigea vers la porte de la chambre\r
+voisine, celle de l'évêque, comme on sait. Arrivé à cette porte, il la\r
+trouva entrebâillée. L'évêque ne l'avait point fermée.\r
+\r
+\r
+\r
+\r
+Chapitre XI\r
+\r
+Ce qu'il fait\r
+\r
+\r
+Jean Valjean écouta. Aucun bruit.\r
+\r
+Il poussa la porte.\r
+\r
+Il la poussa du bout du doigt, légèrement, avec cette douceur furtive et\r
+inquiète d'un chat qui veut entrer.\r
+\r
+La porte céda à la pression et fit un mouvement imperceptible et\r
+silencieux qui élargit un peu l'ouverture.\r
+\r
+Il attendit un moment, puis poussa la porte une seconde fois, plus\r
+hardiment. Elle continua de céder en silence. L'ouverture était assez\r
+grande maintenant pour qu'il pût passer. Mais il y avait près de la\r
+porte une petite table qui faisait avec elle un angle gênant et qui\r
+barrait l'entrée.\r
+\r
+Jean Valjean reconnut la difficulté. Il fallait à toute force que\r
+l'ouverture fût encore élargie.\r
+\r
+Il prit son parti, et poussa une troisième fois la porte, plus\r
+énergiquement que les deux premières. Cette fois il y eut un gond mal\r
+huilé qui jeta tout à coup dans cette obscurité un cri rauque et\r
+prolongé.\r
+\r
+Jean Valjean tressaillit. Le bruit de ce gond sonna dans son oreille\r
+avec quelque chose d'éclatant et de formidable comme le clairon du\r
+jugement dernier. Dans les grossissements fantastiques de la première\r
+minute, il se figura presque que ce gond venait de s'animer et de\r
+prendre tout à coup une vie terrible, et qu'il aboyait comme un chien\r
+pour avertir tout le monde et réveiller les gens endormis.\r
+\r
+Il s'arrêta, frissonnant, éperdu, et retomba de la pointe du pied sur le\r
+talon. Il entendait ses artères battre dans ses tempes comme deux\r
+marteaux de forge, et il lui semblait que son souffle sortait de sa\r
+poitrine avec le bruit du vent qui sort d'une caverne. Il lui paraissait\r
+impossible que l'horrible clameur de ce gond irrité n'eût pas ébranlé\r
+toute la maison comme une secousse de tremblement de terre; la porte,\r
+poussée par lui, avait pris l'alarme et avait appelé; le vieillard\r
+allait se lever, les deux vieilles femmes allaient crier, on viendrait à\r
+l'aide; avant un quart d'heure, la ville serait en rumeur et la\r
+gendarmerie sur pied. Un moment il se crut perdu.\r
+\r
+Il demeura où il était, pétrifié comme la statue de sel, n'osant faire\r
+un mouvement.\r
+\r
+Quelques minutes s'écoulèrent. La porte s'était ouverte toute grande. Il\r
+se hasarda à regarder dans la chambre. Rien n'y avait bougé. Il prêta\r
+l'oreille. Rien ne remuait dans la maison. Le bruit du gond rouillé\r
+n'avait éveillé personne. Ce premier danger était passé, mais il y avait\r
+encore en lui un affreux tumulte. Il ne recula pas pourtant. Même quand\r
+il s'était cru perdu, il n'avait pas reculé. Il ne songea plus qu'à\r
+finir vite. Il fit un pas et entra dans la chambre.\r
+\r
+Cette chambre était dans un calme parfait. On y distinguait çà et là des\r
+formes confuses et vagues qui, au jour, étaient des papiers épars sur\r
+une table, des in-folio ouverts, des volumes empilés sur un tabouret, un\r
+fauteuil chargé de vêtements, un prie-Dieu, et qui à cette heure\r
+n'étaient plus que des coins ténébreux et des places blanchâtres. Jean\r
+Valjean avança avec précaution en évitant de se heurter aux meubles. Il\r
+entendait au fond de la chambre la respiration égale et tranquille de\r
+l'évêque endormi.\r
+\r
+Il s'arrêta tout à coup. Il était près du lit. Il y était arrivé plus\r
+tôt qu'il n'aurait cru.\r
+\r
+La nature mêle quelquefois ses effets et ses spectacles à nos actions\r
+avec une espèce d'à-propos sombre et intelligent, comme si elle voulait\r
+nous faire réfléchir. Depuis près d'une demi-heure un grand nuage\r
+couvrait le ciel. Au moment où Jean Valjean s'arrêta en face du lit, ce\r
+nuage se déchira, comme s'il l'eût fait exprès, et un rayon de lune,\r
+traversant la longue fenêtre, vint éclairer subitement le visage pâle de\r
+l'évêque. Il dormait paisiblement. Il était presque vêtu dans son lit, à\r
+cause des nuits froides des Basses-Alpes, d'un vêtement de laine brune\r
+qui lui couvrait les bras jusqu'aux poignets. Sa tête était renversée\r
+sur l'oreiller dans l'attitude abandonnée du repos; il laissait pendre\r
+hors du lit sa main ornée de l'anneau pastoral et d'où étaient tombées\r
+tant de bonnes oeuvres et de saintes actions. Toute sa face s'illuminait\r
+d'une vague expression de satisfaction, d'espérance et de béatitude.\r
+C'était plus qu'un sourire et presque un rayonnement. Il y avait sur son\r
+front l'inexprimable réverbération d'une lumière qu'on ne voyait pas.\r
+L'âme des justes pendant le sommeil contemple un ciel mystérieux.\r
+\r
+Un reflet de ce ciel était sur l'évêque.\r
+\r
+C'était en même temps une transparence lumineuse, car ce ciel était au\r
+dedans de lui. Ce ciel, c'était sa conscience.\r
+\r
+Au moment où le rayon de lune vint se superposer, pour ainsi dire, à\r
+cette clarté intérieure, l'évêque endormi apparut comme dans une gloire.\r
+Cela pourtant resta doux et voilé d'un demi-jour ineffable. Cette lune\r
+dans le ciel, cette nature assoupie, ce jardin sans un frisson, cette\r
+maison si calme, l'heure, le moment, le silence, ajoutaient je ne sais\r
+quoi de solennel et d'indicible au vénérable repos de ce sage, et\r
+enveloppaient d'une sorte d'auréole majestueuse et sereine ces cheveux\r
+blancs et ces yeux fermés, cette figure où tout était espérance et où\r
+tout était confiance, cette tête de vieillard et ce sommeil d'enfant.\r
+\r
+Il y avait presque de la divinité dans cet homme ainsi auguste à son\r
+insu. Jean Valjean, lui, était dans l'ombre, son chandelier de fer à la\r
+main, debout, immobile, effaré de ce vieillard lumineux. Jamais il\r
+n'avait rien vu de pareil. Cette confiance l'épouvantait. Le monde moral\r
+n'a pas de plus grand spectacle que celui-là: une conscience troublée et\r
+inquiète, parvenue au bord d'une mauvaise action, et contemplant le\r
+sommeil d'un juste.\r
+\r
+Ce sommeil, dans cet isolement, et avec un voisin tel que lui, avait\r
+quelque chose de sublime qu'il sentait vaguement, mais impérieusement.\r
+\r
+Nul n'eût pu dire ce qui se passait en lui, pas même lui. Pour essayer\r
+de s'en rendre compte, il faut rêver ce qu'il y a de plus violent en\r
+présence de ce qu'il y a de plus doux. Sur son visage même on n'eût rien\r
+pu distinguer avec certitude. C'était une sorte d'étonnement hagard. Il\r
+regardait cela. Voilà tout. Mais quelle était sa pensée? Il eût été\r
+impossible de le deviner. Ce qui était évident, c'est qu'il était ému et\r
+bouleversé. Mais de quelle nature était cette émotion?\r
+\r
+Son oeil ne se détachait pas du vieillard. La seule chose qui se\r
+dégageât clairement de son attitude et de sa physionomie, c'était une\r
+étrange indécision. On eût dit qu'il hésitait entre les deux abîmes,\r
+celui où l'on se perd et celui où l'on se sauve. Il semblait prêt à\r
+briser ce crâne ou à baiser cette main.\r
+\r
+Au bout de quelques instants, son bras gauche se leva lentement vers son\r
+front, et il ôta sa casquette, puis son bras retomba avec la même\r
+lenteur, et Jean Valjean rentra dans sa contemplation, sa casquette dans\r
+la main gauche, sa massue dans la main droite, ses cheveux hérissés sur\r
+sa tête farouche.\r
+\r
+L'évêque continuait de dormir dans une paix profonde sous ce regard\r
+effrayant. Un reflet de lune faisait confusément visible au-dessus de la\r
+cheminée le crucifix qui semblait leur ouvrir les bras à tous les deux,\r
+avec une bénédiction pour l'un et un pardon pour l'autre.\r
+\r
+Tout à coup Jean Valjean remit sa casquette sur son front, puis marcha\r
+rapidement, le long du lit, sans regarder l'évêque, droit au placard\r
+qu'il entrevoyait près du chevet; il leva le chandelier de fer comme\r
+pour forcer la serrure; la clef y était; il l'ouvrit; la première chose\r
+qui lui apparut fut le panier d'argenterie; il le prit, traversa la\r
+chambre à grands pas sans précaution et sans s'occuper du bruit, gagna\r
+la porte, rentra dans l'oratoire, ouvrit la fenêtre, saisit un bâton,\r
+enjamba l'appui du rez-de-chaussée, mit l'argenterie dans son sac, jeta\r
+le panier, franchit le jardin, sauta par-dessus le mur comme un tigre,\r
+et s'enfuit.\r
+\r
+\r
+\r
+\r
+Chapitre XII\r
+\r
+L'évêque travaille\r
+\r
+\r
+Le lendemain, au soleil levant, monseigneur Bienvenu se promenait dans\r
+son jardin. Madame Magloire accourut vers lui toute bouleversée.\r
+\r
+--Monseigneur, monseigneur, cria-t-elle, votre grandeur sait-elle où est\r
+le panier d'argenterie?\r
+\r
+--Oui, dit l'évêque.\r
+\r
+--Jésus-Dieu soit béni! reprit-elle. Je ne savais ce qu'il était devenu.\r
+\r
+L'évêque venait de ramasser le panier dans une plate-bande. Il le\r
+présenta à madame Magloire.\r
+\r
+--Le voilà.\r
+\r
+--Eh bien? dit-elle. Rien dedans! et l'argenterie?\r
+\r
+--Ah! repartit l'évêque. C'est donc l'argenterie qui vous occupe? Je ne\r
+sais où elle est.\r
+\r
+--Grand bon Dieu! elle est volée! C'est l'homme d'hier soir qui l'a\r
+volée!\r
+\r
+En un clin d'oeil, avec toute sa vivacité de vieille alerte, madame\r
+Magloire courut à l'oratoire, entra dans l'alcôve et revint vers\r
+l'évêque. L'évêque venait de se baisser et considérait en soupirant un\r
+plant de cochléaria des Guillons que le panier avait brisé en tombant à\r
+travers la plate-bande. Il se redressa au cri de madame Magloire.\r
+\r
+--Monseigneur, l'homme est parti! l'argenterie est volée!\r
+\r
+Tout en poussant cette exclamation, ses yeux tombaient sur un angle du\r
+jardin où l'on voyait des traces d'escalade. Le chevron du mur avait été\r
+arraché.\r
+\r
+--Tenez! c'est par là qu'il s'en est allé. Il a sauté dans la ruelle\r
+Cochefilet! Ah! l'abomination! Il nous a volé notre argenterie!\r
+\r
+L'évêque resta un moment silencieux, puis leva son oeil sérieux, et dit\r
+à madame Magloire avec douceur:\r
+\r
+--Et d'abord, cette argenterie était-elle à nous?\r
+\r
+Madame Magloire resta interdite. Il y eut encore un silence, puis\r
+l'évêque continua:\r
+\r
+--Madame Magloire, je détenais à tort et depuis longtemps cette\r
+argenterie. Elle était aux pauvres. Qu'était-ce que cet homme? Un pauvre\r
+évidemment.\r
+\r
+--Hélas Jésus! repartit madame Magloire. Ce n'est pas pour moi ni pour\r
+mademoiselle. Cela nous est bien égal. Mais c'est pour monseigneur. Dans\r
+quoi monseigneur va-t-il manger maintenant?\r
+\r
+L'évêque la regarda d'un air étonné.\r
+\r
+--Ah çà mais! est-ce qu'il n'y a pas des couverts d'étain?\r
+\r
+Madame Magloire haussa les épaules.\r
+\r
+--L'étain a une odeur.\r
+\r
+--Alors, des couverts de fer.\r
+\r
+Madame Magloire fit une grimace significative.\r
+\r
+--Le fer a un goût.\r
+\r
+--Eh bien, dit l'évêque, des couverts de bois.\r
+\r
+Quelques instants après, il déjeunait à cette même table où Jean Valjean\r
+s'était assis la veille. Tout en déjeunant, monseigneur Bienvenu faisait\r
+gaîment remarquer à sa soeur qui ne disait rien et à madame Magloire qui\r
+grommelait sourdement qu'il n'est nullement besoin d'une cuiller ni\r
+d'une fourchette, même en bois, pour tremper un morceau de pain dans une\r
+tasse de lait.\r
+\r
+--Aussi a-t-on idée! disait madame Magloire toute seule en allant et\r
+venant, recevoir un homme comme cela! et le loger à côté de soi! et quel\r
+bonheur encore qu'il n'ait fait que voler! Ah mon Dieu! cela fait frémir\r
+quand on songe!\r
+\r
+Comme le frère et la soeur allaient se lever de table, on frappa à la\r
+porte.\r
+\r
+--Entrez, dit l'évêque.\r
+\r
+La porte s'ouvrit. Un groupe étrange et violent apparut sur le seuil.\r
+Trois hommes en tenaient un quatrième au collet. Les trois hommes\r
+étaient des gendarmes; l'autre était Jean Valjean.\r
+\r
+Un brigadier de gendarmerie, qui semblait conduire le groupe, était près\r
+de la porte. Il entra et s'avança vers l'évêque en faisant le salut\r
+militaire.\r
+\r
+--Monseigneur... dit-il.\r
+\r
+À ce mot Jean Valjean, qui était morne et semblait abattu, releva la\r
+tête d'un air stupéfait.\r
+\r
+--Monseigneur! murmura-t-il. Ce n'est donc pas le curé?...\r
+\r
+--Silence! dit un gendarme. C'est monseigneur l'évêque.\r
+\r
+Cependant monseigneur Bienvenu s'était approché aussi vivement que son\r
+grand âge le lui permettait.\r
+\r
+--Ah! vous voilà! s'écria-t-il en regardant Jean Valjean. Je suis aise\r
+de vous voir. Et bien mais! je vous avais donné les chandeliers aussi,\r
+qui sont en argent comme le reste et dont vous pourrez bien avoir deux\r
+cents francs. Pourquoi ne les avez-vous pas emportés avec vos couverts?\r
+\r
+Jean Valjean ouvrit les yeux et regarda le vénérable évêque avec une\r
+expression qu'aucune langue humaine ne pourrait rendre.\r
+\r
+--Monseigneur, dit le brigadier de gendarmerie, ce que cet homme disait\r
+était donc vrai? Nous l'avons rencontré. Il allait comme quelqu'un qui\r
+s'en va. Nous l'avons arrêté pour voir. Il avait cette argenterie....\r
+\r
+--Et il vous a dit, interrompit l'évêque en souriant, qu'elle lui avait\r
+été donnée par un vieux bonhomme de prêtre chez lequel il avait passé la\r
+nuit? Je vois la chose. Et vous l'avez ramené ici? C'est une méprise.\r
+\r
+--Comme cela, reprit le brigadier, nous pouvons le laisser aller?\r
+\r
+--Sans doute, répondit l'évêque.\r
+\r
+Les gendarmes lâchèrent Jean Valjean qui recula.\r
+\r
+--Est-ce que c'est vrai qu'on me laisse? dit-il d'une voix presque\r
+inarticulée et comme s'il parlait dans le sommeil.\r
+\r
+--Oui, on te laisse, tu n'entends donc pas? dit un gendarme.\r
+\r
+--Mon ami, reprit l'évêque, avant de vous en aller, voici vos\r
+chandeliers. Prenez-les.\r
+\r
+Il alla à la cheminée, prit les deux flambeaux d'argent et les apporta à\r
+Jean Valjean. Les deux femmes le regardaient faire sans un mot, sans un\r
+geste, sans un regard qui pût déranger l'évêque.\r
+\r
+Jean Valjean tremblait de tous ses membres. Il prit les deux chandeliers\r
+machinalement et d'un air égaré.\r
+\r
+--Maintenant, dit l'évêque, allez en paix.\r
+\r
+--À propos, quand vous reviendrez, mon ami, il est inutile de passer par\r
+le jardin. Vous pourrez toujours entrer et sortir par la porte de la\r
+rue. Elle n'est fermée qu'au loquet jour et nuit.\r
+\r
+Puis se tournant vers la gendarmerie:\r
+\r
+--Messieurs, vous pouvez vous retirer.\r
+\r
+Les gendarmes s'éloignèrent.\r
+\r
+Jean Valjean était comme un homme qui va s'évanouir.\r
+\r
+L'évêque s'approcha de lui, et lui dit à voix basse:\r
+\r
+--N'oubliez pas, n'oubliez jamais que vous m'avez promis d'employer cet\r
+argent à devenir honnête homme.\r
+\r
+Jean Valjean, qui n'avait aucun souvenir d'avoir rien promis, resta\r
+interdit. L'évêque avait appuyé sur ces paroles en les prononçant. Il\r
+reprit avec une sorte de solennité:\r
+\r
+--Jean Valjean, mon frère, vous n'appartenez plus au mal, mais au bien.\r
+C'est votre âme que je vous achète; je la retire aux pensées noires et à\r
+l'esprit de perdition, et je la donne à Dieu.\r

+\r
+Chapitre XIII\r
+\r
+Petit-Gervais\r
+\r
+\r
+Jean Valjean sortit de la ville comme s'il s'échappait. Il se mit à\r
+marcher en toute hâte dans les champs, prenant les chemins et les\r
+sentiers qui se présentaient sans s'apercevoir qu'il revenait à chaque\r
+instant sur ses pas. Il erra ainsi toute la matinée, n'ayant pas mangé\r
+et n'ayant pas faim. Il était en proie à une foule de sensations\r
+nouvelles. Il se sentait une sorte de colère; il ne savait contre qui.\r
+Il n'eût pu dire s'il était touché ou humilié. Il lui venait par moments\r
+un attendrissement étrange qu'il combattait et auquel il opposait\r
+l'endurcissement de ses vingt dernières années. Cet état le fatiguait.\r
+Il voyait avec inquiétude s'ébranler au dedans de lui l'espèce de calme\r
+affreux que l'injustice de son malheur lui avait donné. Il se demandait\r
+qu'est-ce qui remplacerait cela. Parfois il eût vraiment mieux aimé être\r
+en prison avec les gendarmes, et que les choses ne se fussent point\r
+passées ainsi; cela l'eût moins agité. Bien que la saison fut assez\r
+avancée, il y avait encore çà et là dans les haies quelques fleurs\r
+tardives dont l'odeur, qu'il traversait en marchant, lui rappelait des\r
+souvenirs d'enfance. Ces souvenirs lui étaient presque insupportables,\r
+tant il y avait longtemps qu'ils ne lui étaient apparus.\r
+\r
+Des pensées inexprimables s'amoncelèrent ainsi en lui toute la journée.\r
+\r
+Comme le soleil déclinait au couchant, allongeant sur le sol l'ombre du\r
+moindre caillou, Jean Valjean était assis derrière un buisson dans une\r
+grande plaine rousse absolument déserte. Il n'y avait à l'horizon que\r
+les Alpes. Pas même le clocher d'un village lointain. Jean Valjean\r
+pouvait être à trois lieues de Digne. Un sentier qui coupait la plaine\r
+passait à quelques pas du buisson.\r
+\r
+Au milieu de cette méditation qui n'eût pas peu contribué à rendre ses\r
+haillons effrayants pour quelqu'un qui l'eût rencontré, il entendit un\r
+bruit joyeux.\r
+\r
+Il tourna la tête, et vit venir par le sentier un petit savoyard d'une\r
+dizaine d'années qui chantait, sa vielle au flanc et sa boîte à marmotte\r
+sur le dos; un de ces doux et gais enfants qui vont de pays en pays,\r
+laissant voir leurs genoux par les trous de leur pantalon.\r
+\r
+Tout en chantant l'enfant interrompait de temps en temps sa marche et\r
+jouait aux osselets avec quelques pièces de monnaie qu'il avait dans sa\r
+main, toute sa fortune probablement. Parmi cette monnaie il y avait une\r
+pièce de quarante sous. L'enfant s'arrêta à côté du buisson sans voir\r
+Jean Valjean et fit sauter sa poignée de sous que jusque-là il avait\r
+reçue avec assez d'adresse tout entière sur le dos de sa main.\r
+\r
+Cette fois la pièce de quarante sous lui échappa, et vint rouler vers la\r
+broussaille jusqu'à Jean Valjean.\r
+\r
+Jean Valjean posa le pied dessus.\r
+\r
+Cependant l'enfant avait suivi sa pièce du regard, et l'avait vu.\r
+\r
+Il ne s'étonna point et marcha droit à l'homme.\r
+\r
+C'était un lieu absolument solitaire. Aussi loin que le regard pouvait\r
+s'étendre, il n'y avait personne dans la plaine ni dans le sentier. On\r
+n'entendait que les petits cris faibles d'une nuée d'oiseaux de passage\r
+qui traversaient le ciel à une hauteur immense. L'enfant tournait le dos\r
+au soleil qui lui mettait des fils d'or dans les cheveux et qui\r
+empourprait d'une lueur sanglante la face sauvage de Jean Valjean.\r
+\r
+--Monsieur, dit le petit savoyard, avec cette confiance de l'enfance qui\r
+se compose d'ignorance et d'innocence,--ma pièce?\r
+\r
+--Comment t'appelles-tu? dit Jean Valjean.\r
+\r
+--Petit-Gervais, monsieur.\r
+\r
+--Va-t'en, dit Jean Valjean.\r
+\r
+--Monsieur, reprit l'enfant, rendez-moi ma pièce.\r
+\r
+Jean Valjean baissa la tête et ne répondit pas.\r
+\r
+L'enfant recommença:\r
+\r
+--Ma pièce, monsieur!\r
+\r
+L'oeil de Jean Valjean resta fixé à terre.\r
+\r
+--Ma pièce! cria l'enfant, ma pièce blanche! mon argent! Il semblait que\r
+Jean Valjean n'entendit point. L'enfant le prit au collet de sa blouse\r
+et le secoua. Et en même temps il faisait effort pour déranger le gros\r
+soulier ferré posé sur son trésor.\r
+\r
+--Je veux ma pièce! ma pièce de quarante sous!\r
+\r
+L'enfant pleurait. La tête de Jean Valjean se releva. Il était toujours\r
+assis. Ses yeux étaient troubles. Il considéra l'enfant avec une sorte\r
+d'étonnement, puis il étendit la main vers son bâton et cria d'une voix\r
+terrible:\r
+\r
+--Qui est là?\r
+\r
+--Moi, monsieur, répondit l'enfant. Petit-Gervais! moi! moi! Rendez-moi\r
+mes quarante sous, s'il vous plaît! Ôtez votre pied, monsieur, s'il vous\r
+plaît!\r
+\r
+Puis irrité, quoique tout petit, et devenant presque menaçant:\r
+\r
+--Ah, çà, ôterez-vous votre pied? Ôtez donc votre pied, voyons.\r
+\r
+--Ah! c'est encore toi! dit Jean Valjean, et se dressant brusquement\r
+tout debout, le pied toujours sur la pièce d'argent, il ajouta:--Veux-tu\r
+bien te sauver!\r
+\r
+L'enfant effaré le regarda, puis commença à trembler de la tête aux\r
+pieds, et, après quelques secondes de stupeur, se mit à s'enfuir en\r
+courant de toutes ses forces sans oser tourner le cou ni jeter un cri.\r
+\r
+Cependant à une certaine distance l'essoufflement le força de s'arrêter,\r
+et Jean Valjean, à travers sa rêverie, l'entendit qui sanglotait.\r
+\r
+Au bout de quelques instants l'enfant avait disparu. Le soleil s'était\r
+couché. L'ombre se faisait autour de Jean Valjean. Il n'avait pas mangé\r
+de la journée; il est probable qu'il avait la fièvre.\r
+\r
+Il était resté debout, et n'avait pas changé d'attitude depuis que\r
+l'enfant s'était enfui. Son souffle soulevait sa poitrine à des\r
+intervalles longs et inégaux. Son regard, arrêté à dix ou douze pas\r
+devant lui, semblait étudier avec une attention profonde la forme d'un\r
+vieux tesson de faïence bleue tombé dans l'herbe. Tout à coup il\r
+tressaillit; il venait de sentir le froid du soir.\r
+\r
+Il raffermit sa casquette sur son front, chercha machinalement à croiser\r
+et à boutonner sa blouse, fit un pas, et se baissa pour reprendre à\r
+terre son bâton. En ce moment il aperçut la pièce de quarante sous que\r
+son pied avait à demi enfoncée dans la terre et qui brillait parmi les\r
+cailloux.\r
+\r
+Ce fut comme une commotion galvanique. Qu'est-ce que c'est que ça?\r
+dit-il entre ses dents. Il recula de trois pas, puis s'arrêta, sans\r
+pouvoir détacher son regard de ce point que son pied avait foulé\r
+l'instant d'auparavant, comme si cette chose qui luisait là dans\r
+l'obscurité eût été un oeil ouvert fixé sur lui.\r
+\r
+Au bout de quelques minutes, il s'élança convulsivement vers la pièce\r
+d'argent, la saisit, et, se redressant, se mit à regarder au loin dans\r
+la plaine, jetant à la fois ses yeux vers tous les points de l'horizon,\r
+debout et frissonnant comme une bête fauve effarée qui cherche un asile.\r
+\r
+Il ne vit rien. La nuit tombait, la plaine était froide et vague, de\r
+grandes brumes violettes montaient dans la clarté crépusculaire.\r
+\r
+Il dit: «Ah!» et se mit à marcher rapidement dans une certaine\r
+direction, du côté où l'enfant avait disparu. Après une centaine de pas,\r
+il s'arrêta, regarda, et ne vit rien.\r
+\r
+Alors il cria de toute sa force: «Petit-Gervais! Petit-Gervais!»\r
+\r
+Il se tut, et attendit.\r
+\r
+Rien ne répondit.\r
+\r
+La campagne était déserte et morne. Il était environné de l'étendue. Il\r
+n'y avait rien autour de lui qu'une ombre où se perdait son regard et un\r
+silence où sa voix se perdait.\r
+\r
+Une bise glaciale soufflait, et donnait aux choses autour de lui une\r
+sorte de vie lugubre. Des arbrisseaux secouaient leurs petits bras\r
+maigres avec une furie incroyable. On eût dit qu'ils menaçaient et\r
+poursuivaient quelqu'un.\r
+\r
+Il recommença à marcher, puis il se mit à courir, et de temps en temps\r
+il s'arrêtait, et criait dans cette solitude, avec une voix qui était ce\r
+qu'on pouvait entendre de plus formidable et de plus désolé:\r
+«Petit-Gervais! Petit-Gervais!»\r
+\r
+Certes, si l'enfant l'eût entendu, il eût eu peur et se fût bien gardé\r
+de se montrer. Mais l'enfant était sans doute déjà bien loin.\r
+\r
+Il rencontra un prêtre qui était à cheval. Il alla à lui et lui dit:\r
+\r
+--Monsieur le curé, avez-vous vu passer un enfant?\r
+\r
+--Non, dit le prêtre.\r
+\r
+--Un nommé Petit-Gervais?\r
+\r
+--Je n'ai vu personne.\r
+\r
+Il tira deux pièces de cinq francs de sa sacoche et les remit au prêtre.\r
+\r
+--Monsieur le curé, voici pour vos pauvres.--Monsieur le curé, c'est un\r
+petit d'environ dix ans qui a une marmotte, je crois, et une vielle. Il\r
+allait. Un de ces savoyards, vous savez?\r
+\r
+--Je ne l'ai point vu.\r
+\r
+--Petit-Gervais? il n'est point des villages d'ici? pouvez-vous me dire?\r
+\r
+--Si c'est comme vous dites, mon ami, c'est un petit enfant étranger.\r
+Cela passe dans le pays. On ne les connaît pas.\r
+\r
+Jean Valjean prit violemment deux autres écus de cinq francs qu'il donna\r
+au prêtre.\r
+\r
+--Pour vos pauvres, dit-il.\r
+\r
+Puis il ajouta avec égarement:\r
+\r
+--Monsieur l'abbé, faites-moi arrêter. Je suis un voleur.\r
+\r
+Le prêtre piqua des deux et s'enfuit très effrayé.\r
+\r
+Jean Valjean se remit à courir dans la direction qu'il avait d'abord\r
+prise.\r
+\r
+Il fit de la sorte un assez long chemin, regardant, appelant, criant,\r
+mais il ne rencontra plus personne. Deux ou trois fois il courut dans la\r
+plaine vers quelque chose qui lui faisait l'effet d'un être couché ou\r
+accroupi; ce n'étaient que des broussailles ou des roches à fleur de\r
+terre. Enfin, à un endroit où trois sentiers se croisaient, il s'arrêta.\r
+La lune s'était levée. Il promena sa vue au loin et appela une dernière\r
+fois: «Petit-Gervais! Petit-Gervais! Petit-Gervais!» Son cri s'éteignit\r
+dans la brume, sans même éveiller un écho. Il murmura encore:\r
+«Petit-Gervais!» mais d'une voix faible et presque inarticulée. Ce fut\r
+là son dernier effort; ses jarrets fléchirent brusquement sous lui comme\r
+si une puissance invisible l'accablait tout à coup du poids de sa\r
+mauvaise conscience; il tomba épuisé sur une grosse pierre, les poings\r
+dans ses cheveux et le visage dans ses genoux, et il cria: «Je suis un\r
+misérable!»\r
+\r
+Alors son coeur creva et il se mit à pleurer. C'était la première fois\r
+qu'il pleurait depuis dix-neuf ans.\r
+\r
+Quand Jean Valjean était sorti de chez l'évêque, on l'a vu, il était\r
+hors de tout ce qui avait été sa pensée jusque-là. Il ne pouvait se\r
+rendre compte de ce qui se passait en lui. Il se raidissait contre\r
+l'action angélique et contre les douces paroles du vieillard. «Vous\r
+m'avez promis de devenir honnête homme. Je vous achète votre âme. Je la\r
+retire à l'esprit de perversité et je la donne au bon Dieu.» Cela lui\r
+revenait sans cesse. Il opposait à cette indulgence céleste l'orgueil,\r
+qui est en nous comme la forteresse du mal. Il sentait indistinctement\r
+que le pardon de ce prêtre était le plus grand assaut et la plus\r
+formidable attaque dont il eût encore été ébranlé; que son\r
+endurcissement serait définitif s'il résistait à cette clémence; que,\r
+s'il cédait, il faudrait renoncer à cette haine dont les actions des\r
+autres hommes avaient rempli son âme pendant tant d'années, et qui lui\r
+plaisait; que cette fois il fallait vaincre ou être vaincu, et que la\r
+lutte, une lutte colossale et décisive, était engagée entre sa\r
+méchanceté à lui et la bonté de cet homme.\r
+\r
+En présence de toutes ces lueurs, il allait comme un homme ivre. Pendant\r
+qu'il marchait ainsi, les yeux hagards, avait-il une perception\r
+distincte de ce qui pourrait résulter pour lui de son aventure à Digne?\r
+Entendait-il tous ces bourdonnements mystérieux qui avertissent ou\r
+importunent l'esprit à de certains moments de la vie? Une voix lui\r
+disait-elle à l'oreille qu'il venait de traverser l'heure solennelle de\r
+sa destinée, qu'il n'y avait plus de milieu pour lui, que si désormais\r
+il n'était pas le meilleur des hommes il en serait le pire, qu'il\r
+fallait pour ainsi dire que maintenant il montât plus haut que l'évêque\r
+ou retombât plus bas que le galérien, que s'il voulait devenir bon il\r
+fallait qu'il devînt ange; que s'il voulait rester méchant il fallait\r
+qu'il devînt monstre?\r
+\r
+Ici encore il faut se faire ces questions que nous nous sommes déjà\r
+faites ailleurs, recueillait-il confusément quelque ombre de tout ceci\r
+dans sa pensée? Certes, le malheur, nous l'avons dit, fait l'éducation\r
+de l'intelligence; cependant il est douteux que Jean Valjean fût en état\r
+de démêler tout ce que nous indiquons ici. Si ces idées lui arrivaient,\r
+il les entrevoyait plutôt qu'il ne les voyait, et elles ne réussissaient\r
+qu'à le jeter dans un trouble insupportable et presque douloureux. Au\r
+sortir de cette chose difforme et noire qu'on appelle le bagne, l'évêque\r
+lui avait fait mal à l'âme comme une clarté trop vive lui eût fait mal\r
+aux yeux en sortant des ténèbres. La vie future, la vie possible qui\r
+s'offrait désormais à lui toute pure et toute rayonnante le remplissait\r
+de frémissements et d'anxiété. Il ne savait vraiment plus où il en\r
+était. Comme une chouette qui verrait brusquement se lever le soleil, le\r
+forçat avait été ébloui et comme aveuglé par la vertu.\r
+\r
+Ce qui était certain, ce dont il ne se doutait pas, c'est qu'il n'était\r
+déjà plus le même homme, c'est que tout était changé en lui, c'est qu'il\r
+n'était plus en son pouvoir de faire que l'évêque ne lui eût pas parlé\r
+et ne l'eût pas touché.\r
+\r
+Dans cette situation d'esprit, il avait rencontré Petit-Gervais et lui\r
+avait volé ses quarante sous. Pourquoi? Il n'eût assurément pu\r
+l'expliquer; était-ce un dernier effet et comme un suprême effort des\r
+mauvaises pensées qu'il avait apportées du bagne, un reste d'impulsion,\r
+un résultat de ce qu'on appelle en statique la _force acquise_? C'était\r
+cela, et c'était aussi peut-être moins encore que cela. Disons-le\r
+simplement, ce n'était pas lui qui avait volé, ce n'était pas l'homme,\r
+c'était la bête qui, par habitude et par instinct, avait stupidement\r
+posé le pied sur cet argent, pendant que l'intelligence se débattait au\r
+milieu de tant d'obsessions inouïes et nouvelles. Quand l'intelligence\r
+se réveilla et vit cette action de la brute, Jean Valjean recula avec\r
+angoisse et poussa un cri d'épouvante.\r
+\r
+C'est que, phénomène étrange et qui n'était possible que dans la\r
+situation où il était, en volant cet argent à cet enfant, il avait fait\r
+une chose dont il n'était déjà plus capable.\r
+\r
+Quoi qu'il en soit, cette dernière mauvaise action eut sur lui un effet\r
+décisif; elle traversa brusquement ce chaos qu'il avait dans\r
+l'intelligence et le dissipa, mit d'un côté les épaisseurs obscures et\r
+de l'autre la lumière, et agit sur son âme, dans l'état où elle se\r
+trouvait, comme de certains réactifs chimiques agissent sur un mélange\r
+trouble en précipitant un élément et en clarifiant l'autre.\r
+\r
+Tout d'abord, avant même de s'examiner et de réfléchir, éperdu, comme\r
+quelqu'un qui cherche à se sauver, il tâcha de retrouver l'enfant pour\r
+lui rendre son argent, puis, quand il reconnut que cela était inutile et\r
+impossible, il s'arrêta désespéré. Au moment où il s'écria: «je suis un\r
+misérable!» il venait de s'apercevoir tel qu'il était, et il était déjà\r
+à ce point séparé de lui-même, qu'il lui semblait qu'il n'était plus\r
+qu'un fantôme, et qu'il avait là devant lui, en chair et en os, le bâton\r
+à la main, la blouse sur les reins, son sac rempli d'objets volés sur le\r
+dos, avec son visage résolu et morne, avec sa pensée pleine de projets\r
+abominables, le hideux galérien Jean Valjean.\r
+\r
+L'excès du malheur, nous l'avons remarqué, l'avait fait en quelque sorte\r
+visionnaire. Ceci fut donc comme une vision. Il vit véritablement ce\r
+Jean Valjean, cette face sinistre devant lui. Il fut presque au moment\r
+de se demander qui était cet homme, et il en eut horreur.\r
+\r
+Son cerveau était dans un de ces moments violents et pourtant\r
+affreusement calmes où la rêverie est si profonde qu'elle absorbe la\r
+réalité. On ne voit plus les objets qu'on a autour de soi, et l'on voit\r
+comme en dehors de soi les figures qu'on a dans l'esprit.\r
+\r
+Il se contempla donc, pour ainsi dire, face à face, et en même temps, à\r
+travers cette hallucination, il voyait dans une profondeur mystérieuse\r
+une sorte de lumière qu'il prit d'abord pour un flambeau. En regardant\r
+avec plus d'attention cette lumière qui apparaissait à sa conscience, il\r
+reconnut qu'elle avait la forme humaine, et que ce flambeau était\r
+l'évêque.\r
+\r
+Sa conscience considéra tour à tour ces deux hommes ainsi placés devant\r
+elle, l'évêque et Jean Valjean. Il n'avait pas fallu moins que le\r
+premier pour détremper le second. Par un de ces effets singuliers qui\r
+sont propres à ces sortes d'extases, à mesure que sa rêverie se\r
+prolongeait, l'évêque grandissait et resplendissait à ses yeux, Jean\r
+Valjean s'amoindrissait et s'effaçait. À un certain moment il ne fut\r
+plus qu'une ombre. Tout à coup il disparut. L'évêque seul était resté.\r
+\r
+Il remplissait toute l'âme de ce misérable d'un rayonnement magnifique.\r
+Jean Valjean pleura longtemps. Il pleura à chaudes larmes, il pleura à\r
+sanglots, avec plus de faiblesse qu'une femme, avec plus d'effroi qu'un\r
+enfant.\r
+\r
+Pendant qu'il pleurait, le jour se faisait de plus en plus dans son\r
+cerveau, un jour extraordinaire, un jour ravissant et terrible à la\r
+fois. Sa vie passée, sa première faute, sa longue expiation, son\r
+abrutissement extérieur, son endurcissement intérieur, sa mise en\r
+liberté réjouie par tant de plans de vengeance, ce qui lui était arrivé\r
+chez l'évêque, la dernière chose qu'il avait faite, ce vol de quarante\r
+sous à un enfant, crime d'autant plus lâche et d'autant plus monstrueux\r
+qu'il venait après le pardon de l'évêque, tout cela lui revint et lui\r
+apparut, clairement, mais dans une clarté qu'il n'avait jamais vue\r
+jusque-là. Il regarda sa vie, et elle lui parut horrible; son âme, et\r
+elle lui parut affreuse. Cependant un jour doux était sur cette vie et\r
+sur cette âme. Il lui semblait qu'il voyait Satan à la lumière du\r
+paradis.\r
+\r
+Combien d'heures pleura-t-il ainsi? que fit-il après avoir pleuré? où\r
+alla-t-il? on ne l'a jamais su. Il paraît seulement avéré que, dans\r
+cette même nuit, le voiturier qui faisait à cette époque le service de\r
+Grenoble et qui arrivait à Digne vers trois heures du matin, vit en\r
+traversant la rue de l'évêché un homme dans l'attitude de la prière, à\r
+genoux sur le pavé, dans l'ombre, devant la porte de monseigneur\r
+Bienvenu.\r

+Livre troisième--En l'année 1817\r
+\r
+\r
+\r
+\r
+Chapitre I\r
+\r
+L'année 1817\r
+\r
+\r
+1817 est l'année que Louis XVIII, avec un certain aplomb royal qui ne\r
+manquait pas de fierté, qualifiait la vingt-deuxième de son règne. C'est\r
+l'année où M. Bruguière de Sorsum était célèbre. Toutes les boutiques\r
+des perruquiers, espérant la poudre et le retour de l'oiseau royal,\r
+étaient badigeonnées d'azur et fleurdelysées. C'était le temps candide\r
+où le comte Lynch siégeait tous les dimanches comme marguillier au banc\r
+d'oeuvre de Saint-Germain-des-Prés en habit de pair de France, avec son\r
+cordon rouge et son long nez, et cette majesté de profil particulière à\r
+un homme qui a fait une action d'éclat. L'action d'éclat commise par M.\r
+Lynch était ceci: avoir, étant maire de Bordeaux, le 12 mars 1814, donné\r
+la ville un peu trop tôt à M. le duc d'Angoulême. De là sa pairie. En\r
+1817, la mode engloutissait les petits garçons de quatre à six ans sous\r
+de vastes casquettes en cuir maroquiné à oreillons assez ressemblantes à\r
+des mitres d'esquimaux. L'armée française était vêtue de blanc, à\r
+l'autrichienne; les régiments s'appelaient légions; au lieu de chiffres\r
+ils portaient les noms des départements. Napoléon était à Sainte-Hélène,\r
+et, comme l'Angleterre lui refusait du drap vert, il faisait retourner\r
+ses vieux habits. En 1817, Pellegrini chantait, mademoiselle Bigottini\r
+dansait; Potier régnait; Odry n'existait pas encore. Madame Saqui\r
+succédait à Forioso. Il y avait encore des Prussiens en France. M.\r
+Delalot était un personnage. La légitimité venait de s'affirmer en\r
+coupant le poing, puis la tête, à Pleignier, à Carbonneau et à Tolleron.\r
+Le prince de Talleyrand, grand chambellan, et l'abbé Louis, ministre\r
+désigné des finances, se regardaient en riant du rire de deux augures;\r
+tous deux avaient célébré, le 14 juillet 1790, la messe de la Fédération\r
+au Champ de Mars; Talleyrand l'avait dite comme évêque, Louis l'avait\r
+servie comme diacre. En 1817, dans les contre-allées de ce même Champ de\r
+Mars, on apercevait de gros cylindres de bois, gisant sous la pluie,\r
+pourrissant dans l'herbe, peints en bleu avec des traces d'aigles et\r
+d'abeilles dédorées. C'étaient les colonnes qui, deux ans auparavant,\r
+avaient soutenu l'estrade de l'empereur au Champ-de-Mai. Elles étaient\r
+noircies çà et là de la brûlure du bivouac des Autrichiens baraqués près\r
+du Gros-Caillou. Deux ou trois de ces colonnes avaient disparu dans les\r
+feux de ces bivouacs et avaient chauffé les larges mains des\r
+_kaiserlicks_. Le Champ de Mai avait eu cela de remarquable qu'il avait\r
+été tenu au mois de juin et au Champ de Mars. En cette année 1817, deux\r
+choses étaient populaires: le Voltaire-Touquet et la tabatière à la\r
+Charte. L'émotion parisienne la plus récente était le crime de Dautun\r
+qui avait jeté la tête de son frère dans le bassin du Marché-aux-Fleurs.\r
+On commençait à faire au ministère de la marine une enquête sur cette\r
+fatale frégate de la Méduse qui devait couvrir de honte Chaumareix et de\r
+gloire Géricault. Le colonel Selves allait en Égypte pour y devenir\r
+Soliman pacha. Le palais des Thermes, rue de la Harpe, servait de\r
+boutique à un tonnelier. On voyait encore sur la plate-forme de la tour\r
+octogone de l'hôtel de Cluny la petite logette en planches qui avait\r
+servi d'observatoire à Messier, astronome de la marine sous Louis XVI.\r
+La duchesse de Duras lisait à trois ou quatre amis, dans son boudoir\r
+meublé d'X en satin bleu ciel, _Ourika_ inédite. On grattait les N au\r
+Louvre. Le pont d'Austerlitz abdiquait et s'intitulait pont du Jardin du\r
+Roi, double énigme qui déguisait à la fois le pont d'Austerlitz et le\r
+jardin des Plantes. Louis XVIII, préoccupé, tout en annotant du coin de\r
+l'ongle Horace, des héros qui se font empereurs et des sabotiers qui se\r
+font dauphins, avait deux soucis: Napoléon et Mathurin Bruneau.\r
+L'académie française donnait pour sujet de prix: _Le bonheur que procure\r
+l'étude_. M. Bellart était officiellement éloquent. On voyait germer à\r
+son ombre ce futur avocat général de Broè, promis aux sarcasmes de\r
+Paul-Louis Courier. Il y avait un faux Chateaubriand appelé Marchangy,\r
+en attendant qu'il y eut un faux Marchangy appelé d'Arlincourt. _Claire\r
+d'Albe_ et _Malek-Adel_ étaient des chefs-d'oeuvre; madame Cottin était\r
+déclarée le premier écrivain de l'époque. L'institut laissait rayer de\r
+sa liste l'académicien Napoléon Bonaparte. Une ordonnance royale\r
+érigeait Angoulême en école de marine, car, le duc d'Angoulême étant\r
+grand amiral, il était évident que la ville d'Angoulême avait de droit\r
+toutes les qualités d'un port de mer, sans quoi le principe monarchique\r
+eût été entamé. On agitait en conseil des ministres la question de\r
+savoir si l'on devait tolérer les vignettes représentant des voltiges\r
+qui assaisonnaient les affiches de Franconi et qui attroupaient les\r
+polissons des rues. M. Paër, auteur de l'_Agnese_, bonhomme à la face\r
+carrée qui avait une verrue sur la joue, dirigeait les petits concerts\r
+intimes de la marquise de Sassenaye, rue de la Ville-l'Évêque. Toutes\r
+les jeunes filles chantaient _l'Ermite de Saint-Avelle_, paroles\r
+d'Edmond Géraud. _Le Nain jaune_ se transformait en _Miroir_. Le café\r
+Lemblin tenait pour l'empereur contre le café Valois qui tenait pour les\r
+Bourbons. On venait de marier à une princesse de Sicile M. le duc de\r
+Berry, déjà regardé du fond de l'ombre par Louvel. Il y avait un an que\r
+madame de Staël était morte. Les gardes du corps sifflaient mademoiselle\r
+Mars. Les grands journaux étaient tout petits. Le format était\r
+restreint, mais la liberté était grande. _Le Constitutionnel_ était\r
+constitutionnel. _La Minerve_ appelait Chateaubriand _Chateaubriant_. Ce\r
+_t_ faisait beaucoup rire les bourgeois aux dépens du grand écrivain.\r
+Dans des journaux vendus, des journalistes prostitués insultaient les\r
+proscrits de 1815; David n'avait plus de talent, Arnault n'avait plus\r
+d'esprit, Carnot n'avait plus de probité; Soult n'avait gagné aucune\r
+bataille; il est vrai que Napoléon n'avait plus de génie. Personne\r
+n'ignore qu'il est assez rare que les lettres adressées par la poste à\r
+un exilé lui parviennent, les polices se faisant un religieux devoir de\r
+les intercepter. Le fait n'est point nouveau; Descartes, banni, s'en\r
+plaignait. Or, David ayant, dans un journal belge, montré quelque humeur\r
+de ne pas recevoir les lettres qu'on lui écrivait, ceci paraissait\r
+plaisant aux feuilles royalistes qui bafouaient à cette occasion le\r
+proscrit. Dire: _les régicides_, ou dire: _les votants_, dire: _les\r
+ennemis_, ou dire: _les alliés_, dire: _Napoléon_, ou dire: _Buonaparte_,\r
+cela séparait deux hommes plus qu'un abîme. Tous les gens de bons sens\r
+convenaient que l'ère des révolutions était à jamais fermée par le roi\r
+Louis XVIII, surnommé «l'immortel auteur de la charte». Au terre-plein\r
+du Pont-Neuf, on sculptait le mot _Redivivus_, sur le piédestal qui\r
+attendait la statue de Henri IV. M. Piet ébauchait, rue Thérèse, n° 4,\r
+son conciliabule pour consolider la monarchie. Les chefs de la droite\r
+disaient dans les conjonctures graves: «Il faut écrire à Bacot». MM.\r
+Canuel, O'Mahony et de Chappedelaine esquissaient, un peu approuvés de\r
+Monsieur, ce qui devait être plus tard «la conspiration du bord de\r
+l'eau». L'Épingle Noire complotait de son côté. Delaverderie s'abouchait\r
+avec Trogoff. M. Decazes, esprit dans une certaine mesure libéral,\r
+dominait. Chateaubriand, debout tous les matins devant sa fenêtre du n°\r
+27 de la rue Saint-Dominique, en pantalon à pieds et en pantoufles, ses\r
+cheveux gris coiffés d'un madras, les yeux fixés sur un miroir, une\r
+trousse complète de chirurgien dentiste ouverte devant lui, se curait\r
+les dents, qu'il avait charmantes, tout en dictant des variantes de _la\r
+Monarchie selon la Charte_ à M. Pilorge, son secrétaire. La critique\r
+faisant autorité préférait Lafon à Talma. M. de Féletz signait A.; M.\r
+Hoffmann signait Z. Charles Nodier écrivait _Thérèse Aubert_. Le divorce\r
+était aboli. Les lycées s'appelaient collèges. Les collégiens, ornés au\r
+collet d'une fleur de lys d'or, s'y gourmaient à propos du roi de Rome.\r
+La contre-police du château dénonçait à son altesse royale Madame le\r
+portrait, partout exposé, de M. le duc d'Orléans, lequel avait meilleure\r
+mine en uniforme de colonel général des houzards que M. le duc de Berry\r
+en uniforme de colonel général des dragons; grave inconvénient. La ville\r
+de Paris faisait redorer à ses frais le dôme des Invalides. Les hommes\r
+sérieux se demandaient ce que ferait, dans telle ou telle occasion, M.\r
+de Trinquelague; M. Clausel de Montals se séparait, sur divers points,\r
+de M. Clausel de Coussergues; M. de Salaberry n'était pas content. Le\r
+comédien Picard, qui était de l'Académie dont le comédien Molière\r
+n'avait pu être, faisait jouer _les deux Philibert_ à l'Odéon, sur le\r
+fronton duquel l'arrachement des lettres laissait encore lire\r
+distinctement: THÉÂTRE DE L'IMPÉRATRICE. On prenait parti pour ou contre\r
+Cugnet de Montarlot. Fabvier était factieux; Bavoux était\r
+révolutionnaire. Le libraire Pélicier publiait une édition de Voltaire,\r
+sous ce titre: _OEuvres de Voltaire_, de l'Académie française. «Cela\r
+fait venir les acheteurs», disait cet éditeur naïf. L'opinion générale\r
+était que M. Charles Loyson, serait le génie du siècle; l'envie\r
+commençait à le mordre, signe de gloire; et l'on faisait sur lui ce\r
+vers:\r
+\r
+_Même quand Loyson vole, on sent qu'il a des pattes._\r
+\r
+Le cardinal Fesch refusant de se démettre, M. de Pins, archevêque\r
+d'Amasie, administrait le diocèse de Lyon. La querelle de la vallée des\r
+Dappes commençait entre la Suisse et la France par un mémoire du\r
+capitaine Dufour, depuis général. Saint-Simon, ignoré, échafaudait son\r
+rêve sublime. Il y avait à l'académie des sciences un Fourier célèbre\r
+que la postérité a oublié et dans je ne sais quel grenier un Fourier\r
+obscur dont l'avenir se souviendra. Lord Byron commençait à poindre; une\r
+note d'un poème de Millevoye l'annonçait à la France en ces termes: _un\r
+certain lord Baron_. David d'Angers s'essayait à pétrir le marbre.\r
+L'abbé Caron parlait avec éloge, en petit comité de séminaristes, dans\r
+le cul-de-sac des Feuillantines, d'un prêtre inconnu nommé Félicité\r
+Robert qui a été plus tard Lamennais. Une chose qui fumait et clapotait\r
+sur la Seine avec le bruit d'un chien qui nage allait et venait sous les\r
+fenêtres des Tuileries, du pont Royal au pont Louis XV c'était une\r
+mécanique bonne à pas grand'chose, une espèce de joujou, une rêverie\r
+d'inventeur songe-creux, une utopie: un bateau à vapeur. Les Parisiens\r
+regardaient cette inutilité avec indifférence. M. de Vaublanc,\r
+réformateur de l'Institut par coup d'État, ordonnance et fournée, auteur\r
+distingué de plusieurs académiciens, après en avoir fait, ne pouvait\r
+parvenir à l'être. Le faubourg Saint-Germain et la pavillon Marsan\r
+souhaitaient pour préfet de police M. Delaveau, à cause de sa dévotion.\r
+Dupuytren et Récamier se prenaient de querelle à l'amphithéâtre de\r
+l'École de médecine et se menaçaient du poing à propos de la divinité de\r
+Jésus-Christ. Cuvier, un oeil sur la Genèse et l'autre sur la nature,\r
+s'efforçait de plaire à la réaction bigote en mettant les fossiles\r
+d'accord avec les textes et en faisant flatter Moïse par les\r
+mastodontes. M. François de Neufchâteau, louable cultivateur de la\r
+mémoire de Parmentier, faisait mille efforts pour que _pomme de terre_\r
+fût prononcée _parmentière_, et n'y réussissait point. L'abbé Grégoire,\r
+ancien évêque, ancien conventionnel, ancien sénateur, était passé dans\r
+la polémique royaliste à l'état «d'infâme Grégoire». Cette locution que\r
+nous venons d'employer: _passer à l'état de_, était dénoncée comme\r
+néologisme par M. Royer-Collard. On pouvait distinguer encore à sa\r
+blancheur, sous la troisième arche du pont d'Iéna, la pierre neuve avec\r
+laquelle, deux ans auparavant, on avait bouché le trou de mine pratiqué\r
+par Blücher pour faire sauter le pont. La justice appelait à sa barre un\r
+homme qui, en voyant entrer le comte d'Artois à Notre-Dame, avait dit\r
+tout haut: _Sapristi! je regrette le temps où je voyais Bonaparte et\r
+Talma entrer bras dessus bras dessous au Bal-Sauvage_. Propos séditieux.\r
+Six mois de prison. Des traîtres se montraient déboutonnés; des hommes\r
+qui avaient passé à l'ennemi la veille d'une bataille ne cachaient rien\r
+de la récompense et marchaient impudiquement en plein soleil dans le\r
+cynisme des richesses et des dignités; des déserteurs de Ligny et des\r
+Quatre-Bras, dans le débraillé de leur turpitude payée, étalaient leur\r
+dévouement monarchique tout nu; oubliant ce qui est écrit en Angleterre\r
+sur la muraille intérieure des water-closets publics: _Please adjust\r
+your dress before leaving_.\r
+\r
+Voilà, pêle-mêle, ce qui surnage confusément de l'année 1817, oubliée\r
+aujourd'hui. L'histoire néglige presque toutes ces particularités, et ne\r
+peut faire autrement; l'infini l'envahirait. Pourtant ces détails, qu'on\r
+appelle à tort petits--il n'y a ni petits faits dans l'humanité, ni\r
+petites feuilles dans la végétation--sont utiles. C'est de la\r
+physionomie des années que se compose la figure des siècles.\r
+\r
+En cette année 1817, quatre jeunes Parisiens firent «une bonne farce».\r
+\r
+\r
+\r
+\r
+Chapitre II\r
+\r
+Double quatuor\r
+\r
+\r
+Ces Parisiens étaient l'un de Toulouse, l'autre de Limoges, le troisième\r
+de Cahors et le quatrième de Montauban; mais ils étaient étudiants, et\r
+qui dit étudiant dit parisien; étudier à Paris, c'est naître à Paris.\r
+\r
+Ces jeunes gens étaient insignifiants; tout le monde a vu ces\r
+figures-là; quatre échantillons du premier venu; ni bons ni mauvais, ni\r
+savants ni ignorants, ni des génies ni des imbéciles; beaux de ce\r
+charmant avril qu'on appelle vingt ans. C'étaient quatre Oscars\r
+quelconques, car à cette époque les Arthurs n'existaient pas encore.\r
+_Brûlez pour lui les parfums d'Arabie_, s'écriait la romance, _Oscar\r
+s'avance, Oscar, je vais le voir!_ On sortait d'Ossian, l'élégance était\r
+scandinave et calédonienne, le genre anglais pur ne devait prévaloir que\r
+plus tard, et le premier des Arthurs, Wellington, venait à peine de\r
+gagner la bataille de Waterloo.\r
+\r
+Ces Oscars s'appelaient l'un Félix Tholomyès, de Toulouse; l'autre\r
+Listolier, de Cahors; l'autre Fameuil, de Limoges; le dernier\r
+Blachevelle, de Montauban. Naturellement chacun avait sa maîtresse.\r
+Blachevelle aimait Favourite, ainsi nommée parce qu'elle était allée en\r
+Angleterre; Listolier adorait Dahlia, qui avait pris pour nom de guerre\r
+un nom de fleur; Fameuil idolâtrait Zéphine, abrégé de Joséphine;\r
+Tholomyès avait Fantine, dite la Blonde à cause de ses beaux cheveux\r
+couleur de soleil.\r
+\r
+Favourite, Dahlia, Zéphine et Fantine étaient quatre ravissantes filles,\r
+parfumées et radieuses, encore un peu ouvrières, n'ayant pas tout à fait\r
+quitté leur aiguille, dérangées par les amourettes, mais ayant sur le\r
+visage un reste de la sérénité du travail et dans l'âme cette fleur\r
+d'honnêteté qui dans la femme survit à la première chute. Il y avait une\r
+des quatre qu'on appelait la jeune, parce qu'elle était la cadette; et\r
+une qu'on appelait la vieille. La vieille avait vingt-trois ans. Pour ne\r
+rien celer, les trois premières étaient plus expérimentées, plus\r
+insouciantes et plus envolées dans le bruit de la vie que Fantine la\r
+Blonde, qui en était à sa première illusion.\r
+\r
+Dahlia, Zéphine, et surtout Favourite, n'en auraient pu dire autant. Il\r
+y avait déjà plus d'un épisode à leur roman à peine commencé, et\r
+l'amoureux, qui s'appelait Adolphe au premier chapitre, se trouvait être\r
+Alphonse au second, et Gustave au troisième. Pauvreté et coquetterie\r
+sont deux conseillères fatales, l'une gronde, l'autre flatte; et les\r
+belles filles du peuple les ont toutes les deux qui leur parlent bas à\r
+l'oreille, chacune de son côté. Ces âmes mal gardées écoutent. De là les\r
+chutes qu'elles font et les pierres qu'on leur jette. On les accable\r
+avec la splendeur de tout ce qui est immaculé et inaccessible. Hélas! si\r
+la _Yungfrau_ avait faim?\r
+\r
+Favourite, ayant été en Angleterre, avait pour admiratrices Zéphine et\r
+Dahlia. Elle avait eu de très bonne heure un chez-soi. Son père était un\r
+vieux professeur de mathématiques brutal et qui gasconnait; point marié,\r
+courant le cachet malgré l'âge. Ce professeur, étant jeune, avait vu un\r
+jour la robe d'une femme de chambre s'accrocher à un garde-cendre; il\r
+était tombé amoureux de cet accident. Il en était résulté Favourite.\r
+Elle rencontrait de temps en temps son père, qui la saluait. Un matin,\r
+une vieille femme à l'air béguin était entrée chez elle et lui avait\r
+dit:\r
+\r
+--Vous ne me connaissez pas, mademoiselle?\r
+\r
+--Non.\r
+\r
+--Je suis ta mère.\r
+\r
+Puis la vieille avait ouvert le buffet, bu et mangé, fait apporter un\r
+matelas qu'elle avait, et s'était installée. Cette mère, grognon et\r
+dévote, ne parlait jamais à Favourite, restait des heures sans souffler\r
+mot, déjeunait, dînait et soupait comme quatre, et descendait faire\r
+salon chez le portier, où elle disait du mal de sa fille.\r
+\r
+Ce qui avait entraîné Dahlia vers Listolier, vers d'autres peut-être,\r
+vers l'oisiveté, c'était d'avoir de trop jolis ongles roses. Comment\r
+faire travailler ces ongles-là? Qui veut rester vertueuse ne doit pas\r
+avoir pitié de ses mains. Quant à Zéphine, elle avait conquis Fameuil\r
+par sa petite manière mutine et caressante de dire: «Oui, monsieur».\r
+\r
+Les jeunes gens étant camarades, les jeunes filles étaient amies. Ces\r
+amours-là sont toujours doublés de ces amitiés-là.\r
+\r
+Sage et philosophe, c'est deux; et ce qui le prouve, c'est que, toutes\r
+réserves faites sur ces petits ménages irréguliers, Favourite, Zéphine\r
+et Dahlia étaient des filles philosophes, et Fantine une fille sage.\r
+\r
+Sage, dira-t-on? et Tholomyès? Salomon répondrait que l'amour fait\r
+partie de la sagesse. Nous nous bornons à dire que l'amour de Fantine\r
+était un premier amour, un amour unique, un amour fidèle.\r
+\r
+Elle était la seule des quatre qui ne fût tutoyée que par un seul.\r
+\r
+Fantine était un de ces êtres comme il en éclôt, pour ainsi dire, au\r
+fond du peuple. Sortie des plus insondables épaisseurs de l'ombre\r
+sociale, elle avait au front le signe de l'anonyme et de l'inconnu. Elle\r
+était née à Montreuil-sur-mer. De quels parents? Qui pourrait le dire?\r
+On ne lui avait jamais connu ni père ni mère. Elle se nommait Fantine.\r
+Pourquoi Fantine? On ne lui avait jamais connu d'autre nom. À l'époque\r
+de sa naissance, le Directoire existait encore. Point de nom de famille,\r
+elle n'avait pas de famille; point de nom de baptême, l'église n'était\r
+plus là. Elle s'appela comme il plut au premier passant qui la rencontra\r
+toute petite, allant pieds nus dans la rue. Elle reçut un nom comme elle\r
+recevait l'eau des nuées sur son front quand il pleuvait. On l'appela la\r
+petite Fantine. Personne n'en savait davantage. Cette créature humaine\r
+était venue dans la vie comme cela. À dix ans, Fantine quitta la ville\r
+et s'alla mettre en service chez des fermiers des environs. À quinze\r
+ans, elle vint à Paris "chercher fortune". Fantine était belle et resta\r
+pure le plus longtemps qu'elle put. C'était une jolie blonde avec de\r
+belles dents. Elle avait de l'or et des perles pour dot, mais son or\r
+était sur sa tête et ses perles étaient dans sa bouche.\r
+\r
+Elle travailla pour vivre; puis, toujours pour vivre, car le coeur a sa\r
+faim aussi, elle aima.\r
+\r
+Elle aima Tholomyès.\r
+\r
+Amourette pour lui, passion pour elle. Les rues du quartier latin,\r
+qu'emplit le fourmillement des étudiants et des grisettes, virent le\r
+commencement de ce songe. Fantine, dans ces dédales de la colline du\r
+Panthéon, où tant d'aventures se nouent et se dénouent, avait fui\r
+longtemps Tholomyès, mais de façon à le rencontrer toujours. Il y a une\r
+manière d'éviter qui ressemble à chercher. Bref, l'églogue eut lieu.\r
+\r
+Blachevelle, Listolier et Fameuil formaient une sorte de groupe dont\r
+Tholomyès était la tête. C'était lui qui avait l'esprit.\r
+\r
+Tholomyès était l'antique étudiant vieux; il était riche; il avait\r
+quatre mille francs de rente; quatre mille francs de rente, splendide\r
+scandale sur la montagne Sainte-Geneviève. Tholomyès était un viveur de\r
+trente ans, mal conservé. Il était ridé et édenté; et il ébauchait une\r
+calvitie dont il disait lui-même sans tristesse: _crâne à trente ans,\r
+genou à quarante_. Il digérait médiocrement, et il lui était venu un\r
+larmoiement à un oeil. Mais à mesure que sa jeunesse s'éteignait, il\r
+allumait sa gaîté; il remplaçait ses dents par des lazzis, ses cheveux\r
+par la joie, sa santé par l'ironie, et son oeil qui pleurait riait sans\r
+cesse. Il était délabré, mais tout en fleurs. Sa jeunesse, pliant bagage\r
+bien avant l'âge, battait en retraite en bon ordre, éclatait de rire, et\r
+l'on n'y voyait que du feu. Il avait eu une pièce refusée au Vaudeville.\r
+Il faisait çà et là des vers quelconques. En outre, il doutait\r
+supérieurement de toute chose, grande force aux yeux des faibles. Donc,\r
+étant ironique et chauve, il était le chef. _Iron_ est un mot anglais\r
+qui veut dire fer. Serait-ce de là que viendrait ironie?\r
+\r
+Un jour Tholomyès prit à part les trois autres, fît un geste d'oracle,\r
+et leur dit:\r
+\r
+--Il y a bientôt un an que Fantine, Dahlia, Zéphine et Favourite nous\r
+demandent de leur faire une surprise. Nous la leur avons promise\r
+solennellement. Elles nous en parlent toujours, à moi surtout. De même\r
+qu'à Naples les vieilles femmes crient à saint Janvier: _Faccia\r
+gialluta, fa o miracolo_. Face jaune, fais ton miracle! nos belles me\r
+disent sans cesse: «Tholomyès, quand accoucheras-tu de ta surprise?» En\r
+même temps nos parents nous écrivent. Scie des deux côtés. Le moment me\r
+semble venu. Causons.\r
+\r
+Sur ce, Tholomyès baissa la voix, et articula mystérieusement quelque\r
+chose de si gai qu'un vaste et enthousiaste ricanement sortit des quatre\r
+bouches à la fois et que Blachevelle s'écria:\r
+\r
+--Ça, c'est une idée!\r
+\r
+Un estaminet plein de fumée se présenta, ils y entrèrent, et le reste de\r
+leur conférence se perdit dans l'ombre.\r
+\r
+Le résultat de ces ténèbres fut une éblouissante partie de plaisir qui\r
+eut lieu le dimanche suivant, les quatre jeunes gens invitant les quatre\r
+jeunes filles.\r
+\r
+\r
+\r
+\r
+Chapitre III\r
+\r
+Quatre à quatre\r
+\r
+\r
+Ce qu'était une partie de campagne d'étudiants et de grisettes, il y a\r
+quarante-cinq ans, on se le représente malaisément aujourd'hui. Paris\r
+n'a plus les mêmes environs; la figure de ce qu'on pourrait appeler la\r
+vie circumparisienne a complètement changé depuis un demi-siècle; où il\r
+y avait le coucou, il y a le wagon; où il y avait la patache, il y a le\r
+bateau à vapeur; on dit aujourd'hui Fécamp comme on disait Saint-Cloud.\r
+Le Paris de 1862 est une ville qui a la France pour banlieue.\r
+\r
+Les quatre couples accomplirent consciencieusement toutes les folies\r
+champêtres possibles alors. On entrait dans les vacances, et c'était une\r
+chaude et claire journée d'été. La veille, Favourite, la seule qui sût\r
+écrire, avait écrit ceci à Tholomyès au nom des quatre: «C'est un bonne\r
+heure de sortir de bonheur.» C'est pourquoi ils se levèrent à cinq\r
+heures du matin. Puis ils allèrent à Saint-Cloud par le coche,\r
+regardèrent la cascade à sec, et s'écrièrent: «Cela doit être bien beau\r
+quand il y a de l'eau!» déjeunèrent à la _Tête-Noire_, où Castaing\r
+n'avait pas encore passé, se payèrent une partie de bagues au quinconce\r
+du grand bassin, montèrent à la lanterne de Diogène, jouèrent des\r
+macarons à la roulette du pont de Sèvres, cueillirent des bouquets à\r
+Puteaux, achetèrent des mirlitons à Neuilly, mangèrent partout des\r
+chaussons de pommes, furent parfaitement heureux.\r
+\r
+Les jeunes filles bruissaient et bavardaient comme des fauvettes\r
+échappées. C'était un délire. Elles donnaient par moments de petites\r
+tapes aux jeunes gens. Ivresse matinale de la vie! Adorables années!\r
+L'aile des libellules frissonne. Oh! qui que vous soyez, vous\r
+souvenez-vous? Avez-vous marché dans les broussailles, en écartant les\r
+branches à cause de la tête charmante qui vient derrière vous? Avez-vous\r
+glissé en riant sur quelque talus mouillé par la pluie avec une femme\r
+aimée qui vous retient par la main et qui s'écrie: «Ah! mes brodequins\r
+tout neufs! dans quel état ils sont!»\r
+\r
+Disons tout de suite que cette joyeuse contrariété, une ondée, manqua à\r
+cette compagnie de belle humeur, quoique Favourite eût dit en partant,\r
+avec un accent magistral et maternel: _Les limaces se promènent dans les\r
+sentiers. Signe de pluie, mes enfants_.\r
+\r
+Toutes quatre étaient follement jolies. Un bon vieux poète classique,\r
+alors en renom, un bonhomme qui avait une Éléonore, M. le chevalier de\r
+Labouïsse, errant ce jour-là sous les marronniers de Saint-Cloud, les\r
+vit passer vers dix heures du matin; il s'écria: _Il y en a une de\r
+trop_, songeant aux Grâces. Favourite, l'amie de Blachevelle, celle de\r
+vingt-trois ans, la vieille, courait en avant sous les grandes branches\r
+vertes, sautait les fossés, enjambait éperdument les buissons, et\r
+présidait cette gaîté avec une verve de jeune faunesse. Zéphine et\r
+Dahlia, que le hasard avait faites belles de façon qu'elles se faisaient\r
+valoir en se rapprochant et se complétaient, ne se quittaient point, par\r
+instinct de coquetterie plus encore que par amitié, et, appuyées l'une à\r
+l'autre, prenaient des poses anglaises; les premiers _keepsakes_\r
+venaient de paraître, la mélancolie pointait pour les femmes, comme,\r
+plus tard, le byronisme pour les hommes, et les cheveux du sexe tendre\r
+commençaient à s'éplorer. Zéphine et Dahlia étaient coiffées en\r
+rouleaux. Listolier et Fameuil, engagés dans une discussion sur leurs\r
+professeurs, expliquaient à Fantine la différence qu'il y avait entre M.\r
+Delvincourt et M. Blondeau.\r
+\r
+Blachevelle semblait avoir été créé expressément pour porter sur son\r
+bras le dimanche le châle-ternaux boiteux de Favourite.\r
+\r
+Tholomyès suivait, dominant le groupe. Il était très gai, mais on\r
+sentait en lui le gouvernement; il y avait de la dictature dans sa\r
+jovialité; son ornement principal était un pantalon jambes-d'éléphant,\r
+en nankin, avec sous-pieds de tresse de cuivre; il avait un puissant\r
+rotin de deux cents francs à la main, et, comme il se permettait tout,\r
+une chose étrange appelée cigare, à la bouche. Rien n'étant sacré pour\r
+lui, il fumait.\r
+\r
+--Ce Tholomyès est étonnant, disaient les autres avec vénération. Quels\r
+pantalons! quelle énergie!\r
+\r
+Quant à Fantine, c'était la joie. Ses dents splendides avaient\r
+évidemment reçu de Dieu une fonction, le rire. Elle portait à sa main\r
+plus volontiers que sur sa tête son petit chapeau de paille cousue, aux\r
+longues brides blanches. Ses épais cheveux blonds, enclins à flotter et\r
+facilement dénoués et qu'il fallait rattacher sans cesse, semblaient\r
+faits pour la fuite de Galatée sous les saules. Ses lèvres roses\r
+babillaient avec enchantement. Les coins de sa bouche voluptueusement\r
+relevés, comme aux mascarons antiques d'Érigone, avaient l'air\r
+d'encourager les audaces; mais ses longs cils pleins d'ombre\r
+s'abaissaient discrètement sur ce brouhaha du bas du visage comme pour\r
+mettre le holà. Toute sa toilette avait on ne sait quoi de chantant et\r
+de flambant. Elle avait une robe de barège mauve, de petits\r
+souliers-cothurnes mordorés dont les rubans traçaient des X sur son fin\r
+bas blanc à jour, et cette espèce de spencer en mousseline, invention\r
+marseillaise, dont le nom, canezou, corruption du mot _quinze août_\r
+prononcé à la Canebière, signifie beau temps, chaleur et midi. Les trois\r
+autres, moins timides, nous l'avons dit, étaient décolletées tout net,\r
+ce qui, l'été, sous des chapeaux couverts de fleurs, a beaucoup de grâce\r
+et d'agacerie; mais, à côté de ces ajustements hardis, le canezou de la\r
+blonde Fantine, avec ses transparences, ses indiscrétions et ses\r
+réticences, cachant et montrant à la fois, semblait une trouvaille\r
+provocante de la décence, et la fameuse cour d'amour, présidée par la\r
+vicomtesse de Cette aux yeux vert de mer, eût peut-être donné le prix de\r
+la coquetterie à ce canezou qui concourait pour la chasteté. Le plus\r
+naïf est quelquefois le plus savant. Cela arrive.\r
+\r
+Éclatante de face, délicate de profil, les yeux d'un bleu profond, les\r
+paupières grasses, les pieds cambrés et petits, les poignets et les\r
+chevilles admirablement emboîtés, la peau blanche laissant voir çà et là\r
+les arborescences azurées des veines, la joue puérile et franche, le cou\r
+robuste des Junons éginétiques, la nuque forte et souple, les épaules\r
+modelées comme par Coustou, ayant au centre une voluptueuse fossette\r
+visible à travers la mousseline; une gaîté glacée de rêverie;\r
+sculpturale et exquise; telle était Fantine; et l'on devinait sous ces\r
+chiffons une statue, et dans cette statue une âme.\r
+\r
+Fantine était belle, sans trop le savoir. Les rares songeurs, prêtres\r
+mystérieux du beau, qui confrontent silencieusement toute chose à la\r
+perfection, eussent entrevu en cette petite ouvrière, à travers la\r
+transparence de la grâce parisienne, l'antique euphonie sacrée. Cette\r
+fille de l'ombre avait de la race. Elle était belle sous les deux\r
+espèces, qui sont le style et le rythme. Le style est la forme de\r
+l'idéal; le rythme en est le mouvement.\r
+\r
+Nous avons dit que Fantine était la joie, Fantine était aussi la pudeur.\r
+\r
+Pour un observateur qui l'eût étudiée attentivement, ce qui se dégageait\r
+d'elle, à travers toute cette ivresse de l'âge, de la saison et de\r
+l'amourette, c'était une invincible expression de retenue et de\r
+modestie. Elle restait un peu étonnée. Ce chaste étonnement-là est la\r
+nuance qui sépare Psyché de Vénus. Fantine avait les longs doigts blancs\r
+et fins de la vestale qui remue les cendres du feu sacré avec une\r
+épingle d'or. Quoiqu'elle n'eût rien refusé, on ne le verra que trop, à\r
+Tholomyès, son visage, au repos, était souverainement virginal; une\r
+sorte de dignité sérieuse et presque austère l'envahissait soudainement\r
+à de certaines heures, et rien n'était singulier et troublant comme de\r
+voir la gaîté s'y éteindre si vite et le recueillement y succéder sans\r
+transition à l'épanouissement. Cette gravité subite, parfois sévèrement\r
+accentuée, ressemblait au dédain d'une déesse. Son front, son nez et son\r
+menton offraient cet équilibre de ligne, très distinct de l'équilibre de\r
+proportion, et d'où résulte l'harmonie du visage; dans l'intervalle si\r
+caractéristique qui sépare la base du nez de la lèvre supérieure, elle\r
+avait ce pli imperceptible et charmant, signe mystérieux de la chasteté\r
+qui rendit Barberousse amoureux d'une Diane trouvée dans les fouilles\r
+d'Icône.\r
+\r
+L'amour est une faute; soit. Fantine était l'innocence surnageant sur la\r
+faute.\r
+\r
+\r
+\r
+\r
+Chapitre IV\r
+\r
+Tholomyès est si joyeux qu'il chante une chanson espagnole\r
+\r
+\r
+Cette journée-là était d'un bout à l'autre faite d'aurore. Toute la\r
+nature semblait avoir congé, et rire. Les parterres de Saint-Cloud\r
+embaumaient; le souffle de la Seine remuait vaguement les feuilles;\r
+les branches gesticulaient dans le vent; les abeilles mettaient les\r
+jasmins au pillage; toute une bohème de papillons s'ébattait dans les\r
+achillées, les trèfles et les folles avoines; il y avait dans l'auguste\r
+parc du roi de France un tas de vagabonds, les oiseaux.\r
+\r
+Les quatre joyeux couples, mêlés au soleil, aux champs, aux fleurs, aux\r
+arbres, resplendissaient.\r
+\r
+Et, dans cette communauté de paradis, parlant, chantant, courant,\r
+dansant, chassant aux papillons, cueillant des liserons, mouillant leurs\r
+bas à jour roses dans les hautes herbes, fraîches, folles, point\r
+méchantes, toutes recevaient un peu çà et là les baisers de tous,\r
+excepté Fantine, enfermée dans sa vague résistance rêveuse et farouche,\r
+et qui aimait.\r
+\r
+--Toi, lui disait Favourite, tu as toujours l'air chose.\r
+\r
+Ce sont là les joies. Ces passages de couples heureux sont un appel\r
+profond à la vie et à la nature, et font sortir de tout la caresse et la\r
+lumière. Il y avait une fois une fée qui fit les prairies et les arbres\r
+exprès pour les amoureux. De là cette éternelle école buissonnière des\r
+amants qui recommence sans cesse et qui durera tant qu'il y aura des\r
+buissons et des écoliers. De là la popularité du printemps parmi les\r
+penseurs. Le patricien et le gagne-petit, le duc et pair et le robin,\r
+les gens de la cour et les gens de la ville, comme on parlait autrefois,\r
+tous sont sujets de cette fée. On rit, on se cherche, il y a dans l'air\r
+une clarté d'apothéose, quelle transfiguration que d'aimer! Les clercs\r
+de notaire sont des dieux. Et les petits cris, les poursuites dans\r
+l'herbe, les tailles prises au vol, ces jargons qui sont des mélodies,\r
+ces adorations qui éclatent dans la façon de dire une syllabe, ces\r
+cerises arrachées d'une bouche à l'autre, tout cela flamboie et passe\r
+dans des gloires célestes. Les belles filles font un doux gaspillage\r
+d'elles-mêmes. On croit que cela ne finira jamais. Les philosophes, les\r
+poètes, les peintres regardent ces extases et ne savent qu'en faire,\r
+tant cela les éblouit. Le départ pour Cythère! s'écrie Watteau; Lancret,\r
+le peintre de la roture, contemple ses bourgeois envolés dans le bleu;\r
+Diderot tend les bras à toutes ces amourettes, et d'Urfé y mêle des\r
+druides.\r
+\r
+Après le déjeuner les quatre couples étaient allés voir, dans ce qu'on\r
+appelait alors le carré du roi, une plante nouvellement arrivée de\r
+l'Inde, dont le nom nous échappe en ce moment, et qui à cette époque\r
+attirait tout Paris à Saint-Cloud; c'était un bizarre et charmant\r
+arbrisseau haut sur tige, dont les innombrables branches fines comme des\r
+fils, ébouriffées, sans feuilles, étaient couvertes d'un million de\r
+petites rosettes blanches; ce qui faisait que l'arbuste avait l'air\r
+d'une chevelure pouilleuse de fleurs. Il y avait toujours foule à\r
+l'admirer.\r
+\r
+L'arbuste vu, Tholomyès s'était écrié: «J'offre des ânes!» et, prix fait\r
+avec un ânier, ils étaient revenus par Vanves et Issy. À Issy, incident.\r
+Le parc, Bien National possédé à cette époque par le munitionnaire\r
+Bourguin, était d'aventure tout grand ouvert. Ils avaient franchi la\r
+grille, visité l'anachorète mannequin dans sa grotte, essayé les petits\r
+effets mystérieux du fameux cabinet des miroirs, lascif traquenard digne\r
+d'un satyre devenu millionnaire ou de Turcaret métamorphosé en Priape.\r
+Ils avaient robustement secoué le grand filet balançoire attaché aux\r
+deux châtaigniers célébrés par l'abbé de Bernis. Tout en y balançant ces\r
+belles l'une après l'autre, ce qui faisait, parmi les rires universels,\r
+des plis de jupe envolée où Greuze eût trouvé son compte, le toulousain\r
+Tholomyès, quelque peu espagnol, Toulouse est cousine de Tolosa,\r
+chantait, sur une mélopée mélancolique, la vieille chanson _gallega_\r
+probablement inspirée par quelque belle fille lancée à toute volée sur\r
+une corde entre deux arbres:\r
+\r
+ _Soy de Badajoz._\r
+ _Amor me llama._\r
+ _Toda mi alma_\r
+ _Es en mi ojos_\r
+ _Porque enseñas_\r
+ _À tus piernas._\r
+\r
+Fantine seule refusa de se balancer.\r
+\r
+--Je n'aime pas qu'on ait du genre comme ça, murmura assez aigrement\r
+Favourite.\r
+\r
+Les ânes quittés, joie nouvelle; on passa la Seine en bateau, et de\r
+Passy, à pied, ils gagnèrent la barrière de l'Étoile. Ils étaient, on\r
+s'en souvient, debout depuis cinq heures du matin; mais, bah! _il n'y a\r
+pas de lassitude le dimanche_, disait Favourite; _le dimanche, la\r
+fatigue ne travaille pas_. Vers trois heures les quatre couples, effarés\r
+de bonheur, dégringolaient aux montagnes russes, édifice singulier qui\r
+occupait alors les hauteurs Beaujon et dont on apercevait la ligne\r
+serpentante au-dessus des arbres des Champs-Élysées.\r
+\r
+De temps en temps Favourite s'écriait:\r
+\r
+--Et la surprise? je demande la surprise.\r
+\r
+--Patience, répondait Tholomyès.\r
+\r
+\r
+\r
+\r
+Chapitre V\r
+\r
+Chez Bombarda\r
+\r
+\r
+Les montagnes russes épuisées, on avait songé au dîner; et le radieux\r
+huitain, enfin un peu las, s'était échoué au cabaret Bombarda,\r
+succursale qu'avait établie aux Champs-Élysées ce fameux restaurateur\r
+Bombarda, dont on voyait alors l'enseigne rue de Rivoli à côté du\r
+passage Delorme.\r
+\r
+Une chambre grande, mais laide, avec alcôve et lit au fond (vu la\r
+plénitude du cabaret le dimanche, il avait fallu accepter ce gîte); deux\r
+fenêtres d'où l'on pouvait contempler, à travers les ormes, le quai et\r
+la rivière; un magnifique rayon d'août effleurant les fenêtres; deux\r
+tables; sur l'une une triomphante montagne de bouquets mêlés à des\r
+chapeaux d'hommes et de femmes; à l'autre les quatre couples attablés\r
+autour d'un joyeux encombrement de plats, d'assiettes, de verres et de\r
+bouteilles; des cruchons de bière mêlés à des flacons de vin; peu\r
+d'ordre sur la table, quelque désordre dessous;\r
+\r
+ _Ils faisaient sous la table_\r
+ _Un bruit, un trique-trac de pieds épouvantable_\r
+\r
+dit Molière.\r
+\r
+Voilà où en était vers quatre heures et demie du soir la bergerade\r
+commencée à cinq heures du matin. Le soleil déclinait, l'appétit\r
+s'éteignait.\r
+\r
+Les Champs-Élysées, pleins de soleil et de foule, n'étaient que lumière\r
+et poussière, deux choses dont se compose la gloire. Les chevaux de\r
+Marly, ces marbres hennissants, se cabraient dans un nuage d'or. Les\r
+carrosses allaient et venaient. Un escadron de magnifiques gardes du\r
+corps, clairon en tête, descendait l'avenue de Neuilly; le drapeau\r
+blanc, vaguement rose au soleil couchant, flottait sur le dôme des\r
+Tuileries. La place de la Concorde, redevenue alors place Louis XV,\r
+regorgeait de promeneurs contents. Beaucoup portaient la fleur de lys\r
+d'argent suspendue au ruban blanc moiré qui, en 1817, n'avait pas encore\r
+tout à fait disparu des boutonnières. Çà et là au milieu des passants\r
+faisant cercle et applaudissant, des rondes de petites filles jetaient\r
+au vent une bourrée bourbonienne alors célèbre, destinée à foudroyer les\r
+Cent-Jours, et qui avait pour ritournelle:\r
+\r
+ _Rendez-nous notre père de Gand,_\r
+ _Rendez-nous notre père._\r
+\r
+Des tas de faubouriens endimanchés, parfois même fleurdelysés comme les\r
+bourgeois, épars dans le grand carré et dans le carré Marigny, jouaient\r
+aux bagues et tournaient sur les chevaux de bois; d'autres buvaient;\r
+quelques-uns, apprentis imprimeurs, avaient des bonnets de papier; on\r
+entendait leurs rires. Tout était radieux. C'était un temps de paix\r
+incontestable et de profonde sécurité royaliste; c'était l'époque où un\r
+rapport intime et spécial du préfet de police Anglès au roi sur les\r
+faubourgs de Paris se terminait par ces lignes: «Tout bien considéré,\r
+sire, il n'y a rien à craindre de ces gens-là. Ils sont insouciants et\r
+indolents comme des chats. Le bas peuple des provinces est remuant,\r
+celui de Paris ne l'est pas. Ce sont tous petits hommes. Sire, il en\r
+faudrait deux bout à bout pour faire un de vos grenadiers. Il n'y a\r
+point de crainte du côté de la populace de la capitale. Il est\r
+remarquable que la taille a encore décru dans cette population depuis\r
+cinquante ans; et le peuple des faubourgs de Paris est plus petit\r
+qu'avant la révolution. Il n'est point dangereux. En somme, c'est de la\r
+canaille bonne.»\r
+\r
+Qu'un chat puisse se changer en lion, les préfets de police ne le\r
+croient pas possible; cela est pourtant, et c'est là le miracle du\r
+peuple de Paris. Le chat d'ailleurs, si méprisé du comte Anglès, avait\r
+l'estime des républiques antiques; il incarnait à leurs yeux la liberté,\r
+et, comme pour servir de pendant à la Minerve aptère du Pirée, il y\r
+avait sur la place publique de Corinthe le colosse de bronze d'un chat.\r
+La police naïve de la restauration voyait trop «en beau» le peuple de\r
+Paris. Ce n'est point, autant qu'on le croit, de la «canaille bonne». Le\r
+Parisien est au Français ce que l'Athénien était au Grec; personne ne\r
+dort mieux que lui, personne n'est plus franchement frivole et paresseux\r
+que lui, personne mieux que lui n'a l'air d'oublier; qu'on ne s'y fie\r
+pas pourtant; il est propre à toute sorte de nonchalance, mais, quand il\r
+y a de la gloire au bout, il est admirable à toute espèce de furie.\r
+Donnez-lui une pique, il fera le 10 août; donnez-lui un fusil, vous\r
+aurez Austerlitz. Il est le point d'appui de Napoléon et la ressource de\r
+Danton. S'agit-il de la patrie? il s'enrôle; s'agit-il de la liberté? il\r
+dépave. Gare! ses cheveux pleins de colère sont épiques; sa blouse se\r
+drape en chlamyde. Prenez garde. De la première rue Greneta venue, il\r
+fera des fourches caudines. Si l'heure sonne, ce faubourien va grandir,\r
+ce petit homme va se lever, et il regardera d'une façon terrible, et son\r
+souffle deviendra tempête, et il sortira de cette pauvre poitrine grêle\r
+assez de vent pour déranger les plis des Alpes. C'est grâce au\r
+faubourien de Paris que la révolution, mêlée aux armées, conquiert\r
+l'Europe. Il chante, c'est sa joie. Proportionnez sa chanson à sa\r
+nature, et vous verrez! Tant qu'il n'a pour refrain que la Carmagnole,\r
+il ne renverse que Louis XVI; faites-lui chanter la Marseillaise, il\r
+délivrera le monde.\r
+\r
+Cette note écrite en marge du rapport Anglès, nous revenons à nos quatre\r
+couples. Le dîner, comme nous l'avons dit, s'achevait.\r
+\r
+\r
+\r
+\r
+Chapitre VI\r
+\r
+Chapitre où l'on s'adore\r
+\r
+\r
+Propos de table et propos d'amour; les uns sont aussi insaisissables que\r
+les autres; les propos d'amour sont des nuées, les propos de table sont\r
+des fumées.\r
+\r
+Fameuil et Dahlia fredonnaient; Tholomyès buvait; Zéphine riait, Fantine\r
+souriait. Listolier soufflait dans une trompette de bois achetée à\r
+Saint-Cloud. Favourite regardait tendrement Blachevelle et disait:\r
+\r
+--Blachevelle, je t'adore.\r
+\r
+Ceci amena une question de Blachevelle:\r
+\r
+--Qu'est-ce que tu ferais, Favourite, si je cessais de t'aimer?\r
+\r
+--Moi! s'écria Favourite. Ah! ne dis pas cela, même pour rire! Si tu\r
+cessais de m'aimer, je te sauterais après, je te grifferais, je te\r
+gratignerais, je te jetterais de l'eau, je te ferais arrêter.\r
+\r
+Blachevelle sourit avec la fatuité voluptueuse d'un homme chatouillé à\r
+l'amour-propre. Favourite reprit:\r
+\r
+--Oui, je crierais à la garde! Ah! je me gênerais par exemple! Canaille!\r
+\r
+Blachevelle, extasié, se renversa sur sa chaise et ferma\r
+orgueilleusement les deux yeux.\r
+\r
+Dahlia, tout en mangeant, dit bas à Favourite dans le brouhaha:\r
+\r
+--Tu l'idolâtres donc bien, ton Blachevelle?\r
+\r
+--Moi, je le déteste, répondit Favourite du même ton en ressaisissant sa\r
+fourchette. Il est avare. J'aime le petit d'en face de chez moi. Il est\r
+très bien, ce jeune homme-là, le connais-tu? On voit qu'il a le genre\r
+d'être acteur. J'aime les acteurs. Sitôt qu'il rentre, sa mère dit: «Ah!\r
+mon Dieu! ma tranquillité est perdue. Le voilà qui va crier. Mais, mon\r
+ami, tu me casses la tête!» Parce qu'il va dans la maison, dans des\r
+greniers à rats, dans des trous noirs, si haut qu'il peut monter,--et\r
+chanter, et déclamer, est-ce que je sais, moi? qu'on l'entend d'en bas!\r
+Il gagne déjà vingt sous par jour chez un avoué à écrire de la chicane.\r
+Il est fils d'un ancien chantre de Saint-Jacques-du-Haut-Pas. Ah! il est\r
+très bien. Il m'idolâtre tant qu'un jour qu'il me voyait faire de la\r
+pâte pour des crêpes, il m'a dit: _Mamselle, faites des beignets de vos\r
+gants et je les mangerai_. Il n'y a que les artistes pour dire des\r
+choses comme ça. Ah! il est très bien. Je suis en train d'être insensée\r
+de ce petit-là. C'est égal, je dis à Blachevelle que je l'adore. Comme\r
+je mens! Hein? comme je mens!\r
+\r
+Favourite fit une pause, et continua:\r
+\r
+--Dahlia, vois-tu, je suis triste. Il n'a fait que pleuvoir tout l'été,\r
+le vent m'agace, le vent ne décolère pas, Blachevelle est très pingre,\r
+c'est à peine s'il y a des petits pois au marché, on ne sait que manger,\r
+j'ai le spleen, comme disent les Anglais, le beurre est si cher! et\r
+puis, vois, c'est une horreur, nous dînons dans un endroit où il y a un\r
+lit, ça me dégoûte de la vie.\r
+\r
+\r
+\r
+\r
+Chapitre VII\r
+\r
+Sagesse de Tholomyès\r
+\r
+\r
+Cependant, tandis que quelques-uns chantaient, les autres causaient\r
+tumultueusement, et tous ensemble; ce n'était plus que du bruit.\r
+Tholomyès intervint:\r
+\r
+--Ne parlons point au hasard ni trop vite, s'écria-t-il. Méditons si\r
+nous voulons être éblouissants. Trop d'improvisation vide bêtement\r
+l'esprit. Bière qui coule n'amasse point de mousse. Messieurs, pas de\r
+hâte. Mêlons la majesté à la ripaille; mangeons avec recueillement;\r
+festinons lentement. Ne nous pressons pas. Voyez le printemps; s'il se\r
+dépêche, il est flambé, c'est-à-dire gelé. L'excès de zèle perd les\r
+pêchers et les abricotiers. L'excès de zèle tue la grâce et la joie des\r
+bons dîners. Pas de zèle, messieurs! Grimod de la Reynière est de l'avis\r
+de Talleyrand.\r
+\r
+Une sourde rébellion gronda dans le groupe.\r
+\r
+--Tholomyès, laisse-nous tranquilles, dit Blachevelle.\r
+\r
+--À bas le tyran! dit Fameuil.\r
+\r
+--Bombarda, Bombance et Bamboche! cria Listolier.\r
+\r
+--Le dimanche existe, reprit Fameuil.\r
+\r
+--Nous sommes sobres, ajouta Listolier.\r
+\r
+--Tholomyès, fit Blachevelle, contemple mon calme.\r
+\r
+--Tu en es le marquis, répondit Tholomyès.\r
+\r
+Ce médiocre jeu de mots fit l'effet d'une pierre dans une mare. Le\r
+marquis de Montcalm était un royaliste alors célèbre. Toutes les\r
+grenouilles se turent.\r
+\r
+--Amis, s'écria Tholomyès, de l'accent d'un homme qui ressaisit\r
+l'empire, remettez-vous. Il ne faut pas que trop de stupeur accueille ce\r
+calembour tombé du ciel. Tout ce qui tombe de la sorte n'est pas\r
+nécessairement digne d'enthousiasme et de respect. Le calembour est la\r
+fiente de l'esprit qui vole. Le lazzi tombe n'importe où; et l'esprit,\r
+après la ponte d'une bêtise, s'enfonce dans l'azur. Une tache blanchâtre\r
+qui s'aplatit sur le rocher n'empêche pas le condor de planer. Loin de\r
+moi l'insulte au calembour! Je l'honore dans la proportion de ses\r
+mérites; rien de plus. Tout ce qu'il y a de plus auguste, de plus\r
+sublime et de plus charmant dans l'humanité, et peut-être hors de\r
+l'humanité, a fait des jeux de mots. Jésus-Christ a fait un calembour\r
+sur saint Pierre, Moïse sur Isaac, Eschyle sur Polynice, Cléopâtre sur\r
+Octave. Et notez que ce calembour de Cléopâtre a précédé la bataille\r
+d'Actium, et que, sans lui, personne ne se souviendrait de la ville de\r
+Toryne, nom grec qui signifie cuiller à pot. Cela concédé, je reviens à\r
+mon exhortation. Mes frères, je le répète, pas de zèle, pas de\r
+tohu-bohu, pas d'excès, même en pointes, gaîtés, liesses et jeux de\r
+mots. Écoutez-moi, j'ai la prudence d'Amphiaraüs et la calvitie de\r
+César. Il faut une limite, même aux rébus. _Est modus in rebus_. Il faut\r
+une limite, même aux dîners. Vous aimez les chaussons aux pommes,\r
+mesdames, n'en abusez pas. Il faut, même en chaussons, du bon sens et de\r
+l'art. La gloutonnerie châtie le glouton. Gula punit Gulax.\r
+L'indigestion est chargée par le bon Dieu de faire de la morale aux\r
+estomacs. Et, retenez ceci: chacune de nos passions, même l'amour, a un\r
+estomac qu'il ne faut pas trop remplir. En toute chose il faut écrire à\r
+temps le mot _finis_, il faut se contenir, quand cela devient urgent,\r
+tirer le verrou sur son appétit, mettre au violon sa fantaisie et se\r
+mener soi-même au poste. Le sage est celui qui sait à un moment donné\r
+opérer sa propre arrestation. Ayez quelque confiance en moi. Parce que\r
+j'ai fait un peu mon droit, à ce que me disent mes examens, parce que je\r
+sais la différence qu'il y a entre la question mue et la question\r
+pendante, parce que j'ai soutenu une thèse en latin sur la manière dont\r
+on donnait la torture à Rome au temps où Munatius Demens était questeur\r
+du Parricide, parce que je vais être docteur, à ce qu'il paraît, il ne\r
+s'ensuit pas de toute nécessité que je sois un imbécile. Je vous\r
+recommande la modération dans vos désirs. Vrai comme je m'appelle Félix\r
+Tholomyès, je parle bien. Heureux celui qui, lorsque l'heure a sonné,\r
+prend un parti héroïque, et abdique comme Sylla, ou Origène!\r
+\r
+Favourite écoutait avec une attention profonde.\r
+\r
+--Félix! dit-elle, quel joli mot! j'aime ce nom-là. C'est en latin. Ça\r
+veut dire Prosper.\r
+\r
+Tholomyès poursuivit:\r
+\r
+--Quirites, gentlemen, Caballeros, mes amis! voulez-vous ne sentir aucun\r
+aiguillon et vous passer de lit nuptial et braver l'amour? Rien de plus\r
+simple. Voici la recette: la limonade, l'exercice outré, le travail\r
+forcé, éreintez-vous, traînez des blocs, ne dormez pas, veillez,\r
+gorgez-vous de boissons nitreuses et de tisanes de nymphaeas, savourez\r
+des émulsions de pavots et d'agnuscastus, assaisonnez-moi cela d'une\r
+diète sévère, crevez de faim, et joignez-y les bains froids, les\r
+ceintures d'herbes, l'application d'une plaque de plomb, les lotions\r
+avec la liqueur de Saturne et les fomentations avec l'oxycrat.\r
+\r
+--J'aime mieux une femme, dit Listolier.\r
+\r
+--La femme! reprit Tholomyès, méfiez-vous-en. Malheur à celui qui se\r
+livre au coeur changeant de la femme! La femme est perfide et tortueuse.\r
+Elle déteste le serpent par jalousie de métier. Le serpent, c'est la\r
+boutique en face.\r
+\r
+--Tholomyès, cria Blachevelle, tu es ivre!\r
+\r
+--Pardieu! dit Tholomyès.\r
+\r
+--Alors sois gai, reprit Blachevelle.\r
+\r
+Et, remplissant son verre, il se leva:\r
+\r
+--Gloire au vin! _Nunc te, Bacche, canam_! Pardon, mesdemoiselles, c'est\r
+de l'espagnol. Et la preuve, señoras, la voici: tel peuple, telle\r
+futaille. L'arrobe de Castille contient seize litres, le cantaro\r
+d'Alicante douze, l'almude des Canaries vingt-cinq, le cuartin des\r
+Baléares vingt-six, la botte du czar Pierre trente. Vive ce czar qui\r
+était grand, et vive sa botte qui était plus grande encore! Mesdames, un\r
+conseil d'ami: trompez-vous de voisin, si bon vous semble. Le propre de\r
+l'amour, c'est d'errer. L'amourette n'est pas faite pour s'accroupir et\r
+s'abrutir comme une servante anglaise qui a le calus du scrobage aux\r
+genoux. Elle n'est pas faite pour cela, elle erre gaîment, la douce\r
+amourette! On a dit: l'erreur est humaine; moi je dis: l'erreur est\r
+amoureuse. Mesdames, je vous idolâtre toutes. Ô Zéphine, ô Joséphine,\r
+figure plus que chiffonnée, vous seriez charmante, si vous n'étiez de\r
+travers. Vous avez l'air d'un joli visage sur lequel, par mégarde, on\r
+s'est assis. Quant à Favourite, ô nymphes et muses! un jour que\r
+Blachevelle passait le ruisseau de la rue Guérin-Boisseau, il vit une\r
+belle fille aux bas blancs et bien tirés qui montrait ses jambes. Ce\r
+prologue lui plut, et Blachevelle aima. Celle qu'il aima était\r
+Favourite. Ô Favourite, tu as des lèvres ioniennes. Il y avait un\r
+peintre grec, appelé Euphorion, qu'on avait surnommé le peintre des\r
+lèvres. Ce Grec seul eût été digne de peindre ta bouche! Écoute! avant\r
+toi, il n'y avait pas de créature digne de ce nom. Tu es faite pour\r
+recevoir la pomme comme Vénus ou pour la manger comme Ève. La beauté\r
+commence à toi. Je viens de parler d'Ève, c'est toi qui l'as créée. Tu\r
+mérites le brevet d'invention de la jolie femme. Ô Favourite, je cesse\r
+de vous tutoyer, parce que je passe de la poésie à la prose. Vous\r
+parliez de mon nom tout à l'heure. Cela m'a attendri; mais, qui que nous\r
+soyons, méfions-nous des noms. Ils peuvent se tromper. Je me nomme Félix\r
+et ne suis pas heureux. Les mots sont des menteurs. N'acceptons pas\r
+aveuglément les indications qu'ils nous donnent. Ce serait une erreur\r
+d'écrire à Liège pour avoir des bouchons et à Pau pour avoir des gants.\r
+Miss Dahlia, à votre place, je m'appellerais Rosa. Il faut que la fleur\r
+sente bon et que la femme ait de l'esprit. Je ne dis rien de Fantine,\r
+c'est une songeuse, une rêveuse, une pensive, une sensitive; c'est un\r
+fantôme ayant la forme d'une nymphe et la pudeur d'une nonne, qui se\r
+fourvoie dans la vie de grisette, mais qui se réfugie dans les\r
+illusions, et qui chante, et qui prie, et qui regarde l'azur sans trop\r
+savoir ce qu'elle voit ni ce qu'elle fait, et qui, les yeux au ciel,\r
+erre dans un jardin où il y a plus d'oiseaux qu'il n'en existe! Ô\r
+Fantine, sache ceci: moi Tholomyès, je suis une illusion; mais elle ne\r
+m'entend même pas, la blonde fille des chimères! Du reste, tout en elle\r
+est fraîcheur, suavité, jeunesse, douce clarté matinale. Ô Fantine,\r
+fille digne de vous appeler marguerite ou perle, vous êtes une femme du\r
+plus bel orient. Mesdames, un deuxième conseil: ne vous mariez point; le\r
+mariage est une greffe; cela prend bien ou mal; fuyez ce risque. Mais,\r
+bah! qu'est-ce que je chante là? Je perds mes paroles. Les filles sont\r
+incurables sur l'épousaille; et tout ce que nous pouvons dire, nous\r
+autres sages, n'empêchera point les giletières et les piqueuses de\r
+bottines de rêver des maris enrichis de diamants. Enfin, soit; mais,\r
+belles, retenez ceci: vous mangez trop de sucre. Vous n'avez qu'un tort,\r
+ô femmes, c'est de grignoter du sucre. Ô sexe rongeur, tes jolies\r
+petites dents blanches adorent le sucre. Or, écoutez bien, le sucre est\r
+un sel. Tout sel est desséchant. Le sucre est le plus desséchant de tous\r
+les sels. Il pompe à travers les veines les liquides du sang; de là la\r
+coagulation, puis la solidification du sang; de là les tubercules dans\r
+le poumon; de là la mort. Et c'est pourquoi le diabète confine à la\r
+phthisie. Donc ne croquez pas de sucre, et vous vivrez! Je me tourne\r
+vers les hommes. Messieurs, faites des conquêtes. Pillez-vous les uns\r
+aux autres sans remords vos bien-aimées. Chassez-croisez. En amour, il\r
+n'y a pas d'amis. Partout où il y a une jolie femme l'hostilité est\r
+ouverte. Pas de quartier, guerre à outrance! Une jolie femme est un\r
+casus belli; une jolie femme est un flagrant délit. Toutes les invasions\r
+de l'histoire sont déterminées par des cotillons. La femme est le droit\r
+de l'homme. Romulus a enlevé les Sabines, Guillaume a enlevé les\r
+Saxonnes, César a enlevé les Romaines. L'homme qui n'est pas aimé plane\r
+comme un vautour sur les amantes d'autrui; et quant à moi, à tous ces\r
+infortunés qui sont veufs, je jette la proclamation sublime de Bonaparte\r
+à l'armée d'Italie: «Soldats, vous manquez de tout. L'ennemi en a.»\r
+\r
+Tholomyès s'interrompit.\r
+\r
+--Souffle, Tholomyès, dit Blachevelle.\r
+\r
+En même temps, Blachevelle, appuyé de Listolier et de Fameuil, entonna\r
+sur un air de complainte une de ces chansons d'atelier composées des\r
+premiers mots venus, rimées richement et pas du tout, vides de sens\r
+comme le geste de l'arbre et le bruit du vent, qui naissent de la vapeur\r
+des pipes et se dissipent et s'envolent avec elle. Voici par quel\r
+couplet le groupe donna la réplique à la harangue de Tholomyès:\r
+\r
+Les pères dindons donnèrent de l'argent à un agent pour que mons\r
+Clermont-Tonnerre fût fait pape à la Saint-Jean; Mais Clermont ne put\r
+pas être fait pape, n'étant pas prêtre.\r
+\r
+Alors leur agent rageant leur rapporta leur argent.\r
+\r
+Ceci n'était pas fait pour calmer l'improvisation de Tholomyès; il vida\r
+son verre, le remplit, et recommença.\r
+\r
+--À bas la sagesse! oubliez tout ce que j'ai dit. Ne soyons ni prudes,\r
+ni prudents, ni prud'hommes. Je porte un toast à l'allégresse; soyons\r
+allègres! Complétons notre cours de droit par la folie et la nourriture.\r
+Indigestion et digeste. Que Justinien soit le mâle et que Ripaille soit\r
+la femelle! Joie dans les profondeurs! Vis, ô création! Le monde est un\r
+gros diamant! Je suis heureux. Les oiseaux sont étonnants. Quelle fête\r
+partout! Le rossignol est un Elleviou gratis. Été, je te salue. Ô\r
+Luxembourg, ô Géorgiques de la rue Madame et de l'allée de\r
+l'Observatoire! Ô pioupious rêveurs! ô toutes ces bonnes charmantes qui,\r
+tout en gardant des enfants, s'amusent à en ébaucher! Les pampas de\r
+l'Amérique me plairaient, si je n'avais les arcades de l'Odéon. Mon âme\r
+s'envole dans les forêts vierges et dans les savanes. Tout est beau. Les\r
+mouches bourdonnent dans les rayons. Le soleil a éternué le colibri.\r
+Embrasse-moi, Fantine!\r
+\r
+Il se trompa, et embrassa Favourite.\r

+Chapitre VIII\r
+\r
+Mort d'un cheval\r
+\r
+\r
+--On dîne mieux chez Edon que chez Bombarda, s'écria Zéphine.\r
+\r
+--Je préfère Bombarda à Edon, déclara Blachevelle. Il a plus de luxe.\r
+C'est plus asiatique. Voyez la salle d'en bas. Il y a des glaces sur les\r
+murs.\r
+\r
+--J'en aime mieux dans mon assiette, dit Favourite.\r
+\r
+Blachevelle insista:\r
+\r
+--Regardez les couteaux. Les manches sont en argent chez Bombarda, et en\r
+os chez Edon. Or, l'argent est plus précieux que l'os.\r
+\r
+--Excepté pour ceux qui ont un menton d'argent, observa Tholomyès.\r
+\r
+Il regardait en cet instant-là le dôme des Invalides, visible des\r
+fenêtres de Bombarda.\r
+\r
+Il y eut une pause.\r
+\r
+--Tholomyès, cria Fameuil, tout à l'heure, Listolier et moi, nous avions\r
+une discussion.\r
+\r
+--Une discussion est bonne, répondit Tholomyès, une querelle vaut mieux.\r
+\r
+--Nous disputions philosophie.\r
+\r
+--Soit.\r
+\r
+--Lequel préfères-tu de Descartes ou de Spinosa?\r
+\r
+--Désaugiers, dit Tholomyès.\r
+\r
+Cet arrêt rendu, il but et reprit:\r
+\r
+--Je consens à vivre. Tout n'est pas fini sur la terre, puisqu'on peut\r
+encore déraisonner. J'en rends grâces aux dieux immortels. On ment, mais\r
+on rit. On affirme, mais on doute. L'inattendu jaillit du syllogisme.\r
+C'est beau. Il est encore ici-bas des humains qui savent joyeusement\r
+ouvrir et fermer la boîte à surprises du paradoxe. Ceci, mesdames, que\r
+vous buvez d'un air tranquille, est du vin de Madère, sachez-le, du cru\r
+de Coural das Freiras qui est à trois cent dix-sept toises au-dessus du\r
+niveau de la mer! Attention en buvant! trois cent dix-sept toises! et\r
+monsieur Bombarda, le magnifique restaurateur, vous donne ces trois cent\r
+dix-sept toises pour quatre francs cinquante centimes!\r
+\r
+Fameuil interrompit de nouveau:\r
+\r
+--Tholomyès, tes opinions font loi. Quel est ton auteur favori?\r
+\r
+--Ber....\r
+\r
+--Quin?\r
+\r
+--Non. Choux.\r
+\r
+Et Tholomyès poursuivit:\r
+\r
+--Honneur à Bombarda! il égalerait Munophis d'Elephanta s'il pouvait me\r
+cueillir une almée, et Thygélion de Chéronée s'il pouvait m'apporter une\r
+hétaïre! car, ô mesdames, il y avait des Bombarda en Grèce et en Égypte.\r
+C'est Apulée qui nous l'apprend. Hélas! toujours les mêmes choses et\r
+rien de nouveau. Plus rien d'inédit dans la création du créateur! _Nil\r
+sub sole novum_, dit Salomon; _amor omnibus idem_, dit Virgile; et\r
+Carabine monte avec Carabin dans la galiote de Saint-Cloud, comme\r
+Aspasie s'embarquait avec Périclès sur la flotte de Samos. Un dernier\r
+mot. Savez-vous ce que c'était qu'Aspasie, mesdames? Quoiqu'elle vécût\r
+dans un temps où les femmes n'avaient pas encore d'âme, c'était une âme;\r
+une âme d'une nuance rose et pourpre, plus embrasée que le feu, plus\r
+franche que l'aurore. Aspasie était une créature en qui se touchaient\r
+les deux extrêmes de la femme; c'était la prostituée déesse. Socrate,\r
+plus Manon Lescaut. Aspasie fut créée pour le cas où il faudrait une\r
+catin à Prométhée.\r
+\r
+Tholomyès, lancé, se serait difficilement arrêté, si un cheval ne se fût\r
+abattu sur le quai en cet instant-là même. Du choc, la charrette et\r
+l'orateur restèrent court. C'était une jument beauceronne, vieille et\r
+maigre et digne de l'équarrisseur, qui traînait une charrette fort\r
+lourde. Parvenue devant Bombarda, la bête, épuisée et accablée, avait\r
+refusé d'aller plus loin. Cet incident avait fait de la foule. À peine\r
+le charretier, jurant et indigné, avait-il eu le temps de prononcer avec\r
+l'énergie convenable le mot sacramentel: _mâtin_! appuyé d'un implacable\r
+coup de fouet, que la haridelle était tombée pour ne plus se relever. Au\r
+brouhaha des passants, les gais auditeurs de Tholomyès tournèrent la\r
+tête, et Tholomyès en profita pour clore son allocution par cette\r
+strophe mélancolique:\r
+\r
+ _Elle était de ce monde où coucous et carrosses_\r
+ _Ont le même destin,_\r
+ _Et, rosse, elle a vécu ce que vivent les rosses,_\r
+ _L'espace d'un: mâtin!_\r
+\r
+--Pauvre cheval, soupira Fantine.\r
+\r
+Et Dahlia s'écria:\r
+\r
+--Voilà Fantine qui va se mettre à plaindre les chevaux! Peut-on être\r
+fichue bête comme ça!\r
+\r
+En ce moment, Favourite, croisant les bras et renversant la tête en\r
+arrière, regarda résolûment Tholomyès et dit:\r
+\r
+--Ah çà! et la surprise?\r
+\r
+--Justement. L'instant est arrivé, répondit Tholomyès. Messieurs,\r
+l'heure de la surprise a sonné. Mesdames, attendez-nous un moment.\r
+\r
+--Cela commence par un baiser, dit Blachevelle.\r
+\r
+--Sur le front, ajouta Tholomyès.\r
+\r
+Chacun déposa gravement un baiser sur le front de sa maîtresse; puis ils\r
+se dirigèrent vers la porte tous les quatre à la file, en mettant leur\r
+doigt sur la bouche.\r
+\r
+Favourite battit des mains à leur sortie.\r
+\r
+--C'est déjà amusant, dit-elle.\r
+\r
+--Ne soyez pas trop longtemps, murmura Fantine. Nous vous attendons.\r
+\r
+\r
+\r
+\r
+Chapitre IX\r
+\r
+Fin joyeuse de la joie\r
+\r
+\r
+Les jeunes filles, restées seules, s'accoudèrent deux à deux sur l'appui\r
+des fenêtres, jasant, penchant leur tête et se parlant d'une croisée à\r
+l'autre.\r
+\r
+Elles virent les jeunes gens sortir du cabaret Bombarda bras dessus bras\r
+dessous; ils se retournèrent, leur firent des signes en riant, et\r
+disparurent dans cette poudreuse cohue du dimanche qui envahit\r
+hebdomadairement les Champs-Élysées.\r
+\r
+--Ne soyez pas longtemps! cria Fantine.\r
+\r
+--Que vont-ils nous rapporter? dit Zéphine.\r
+\r
+--Pour sûr ce sera joli, dit Dahlia.\r
+\r
+--Moi, reprit Favourite, je veux que ce soit en or.\r
+\r
+Elles furent bientôt distraites par le mouvement du bord de l'eau\r
+qu'elles distinguaient dans les branches des grands arbres et qui les\r
+divertissait fort. C'était l'heure du départ des malles-poste et des\r
+diligences. Presque toutes les messageries du midi et de l'ouest\r
+passaient alors par les Champs-Élysées. La plupart suivaient le quai et\r
+sortaient par la barrière de Passy. De minute en minute, quelque grosse\r
+voiture peinte en jaune et en noir, pesamment chargée, bruyamment\r
+attelée, difforme à force de malles, de bâches et de valises, pleine de\r
+têtes tout de suite disparues, broyant la chaussée, changeant tous les\r
+pavés en briquets, se ruait à travers la foule avec toutes les\r
+étincelles d'une forge, de la poussière pour fumée, et un air de furie.\r
+Ce vacarme réjouissait les jeunes filles. Favourite s'exclamait:\r
+\r
+--Quel tapage! on dirait des tas de chaînes qui s'envolent.\r
+\r
+Il arriva une fois qu'une de ces voitures qu'on distinguait\r
+difficilement dans l'épaisseur des ormes, s'arrêta un moment, puis\r
+repartit au galop. Cela étonna Fantine.\r
+\r
+--C'est particulier! dit-elle. Je croyais que la diligence ne s'arrêtait\r
+jamais. Favourite haussa les épaules.\r
+\r
+--Cette Fantine est surprenante. Je viens la voir par curiosité. Elle\r
+s'éblouit des choses les plus simples. Une supposition; je suis un\r
+voyageur, je dis à la diligence: je vais en avant, vous me prendrez sur\r
+le quai en passant. La diligence passe, me voit, s'arrête, et me prend.\r
+Cela se fait tous les jours. Tu ne connais pas la vie, ma chère.\r
+\r
+Un certain temps s'écoula ainsi. Tout à coup Favourite eut le mouvement\r
+de quelqu'un qui se réveille.\r
+\r
+--Eh bien, fit-elle, et la surprise?\r
+\r
+--À propos, oui, reprit Dahlia, la fameuse surprise?\r
+\r
+--Ils sont bien longtemps! dit Fantine.\r
+\r
+Comme Fantine achevait ce soupir, le garçon qui avait servi le dîner\r
+entra. Il tenait à la main quelque chose qui ressemblait à une lettre.\r
+\r
+--Qu'est-ce que cela? demanda Favourite.\r
+\r
+Le garçon répondit:\r
+\r
+--C'est un papier que ces messieurs ont laissé pour ces dames.\r
+\r
+--Pourquoi ne l'avoir pas apporté tout de suite?\r
+\r
+--Parce que ces messieurs, reprit le garçon, ont commandé de ne le\r
+remettre à ces dames qu'au bout d'une heure.\r
+\r
+Favourite arracha le papier des mains du garçon. C'était une lettre en\r
+effet.\r
+\r
+--Tiens! dit-elle. Il n'y a pas d'adresse. Mais voici ce qui est écrit\r
+dessus:\r
+\r
+Ceci est la surprise.\r
+\r
+Elle décacheta vivement la lettre, l'ouvrit et lut (elle savait lire):\r
+\r
+«Ô nos amantes!\r
+\r
+«Sachez que nous avons des parents. Des parents, vous ne connaissez pas\r
+beaucoup ça. Ça s'appelle des pères et mères dans le code civil, puéril\r
+et honnête. Or, ces parents gémissent, ces vieillards nous réclament,\r
+ces bons hommes et ces bonnes femmes nous appellent enfants prodigues,\r
+ils souhaitent nos retours, et nous offrent de tuer des veaux. Nous leur\r
+obéissons, étant vertueux. À l'heure où vous lirez ceci, cinq chevaux\r
+fougueux nous rapporteront à nos papas et à nos mamans. Nous fichons le\r
+camp, comme dit Bossuet. Nous partons, nous sommes partis. Nous fuyons\r
+dans les bras de Laffitte et sur les ailes de Caillard. La diligence de\r
+Toulouse nous arrache à l'abîme, et l'abîme c'est vous, ô nos belles\r
+petites! Nous rentrons dans la société, dans le devoir et dans l'ordre,\r
+au grand trot, à raison de trois lieues à l'heure. Il importe à la\r
+patrie que nous soyons, comme tout le monde, préfets, pères de famille,\r
+gardes champêtres et conseillers d'État. Vénérez-nous. Nous nous\r
+sacrifions. Pleurez-nous rapidement et remplacez-nous vite. Si cette\r
+lettre vous déchire, rendez-le-lui. Adieu.\r
+\r
+«Pendant près de deux ans, nous vous avons rendues heureuses. Ne nous en\r
+gardez pas rancune.\r
+\r
+«Signé: Blachevelle.\r
+\r
+«Fameuil.\r
+\r
+«Listolier.\r
+\r
+«Félix Tholomyès\r
+\r
+«Post-scriptum. Le dîner est payé.»\r
+\r
+Les quatre jeunes filles se regardèrent.\r
+\r
+Favourite rompit la première le silence.\r
+\r
+--Eh bien! s'écria-t-elle, c'est tout de même une bonne farce.\r
+\r
+--C'est très drôle, dit Zéphine.\r
+\r
+--Ce doit être Blachevelle qui a eu cette idée-là, reprit Favourite. Ça\r
+me rend amoureuse de lui. Sitôt parti, sitôt aimé. Voilà l'histoire.\r
+\r
+--Non, dit Dahlia, c'est une idée à Tholomyès. Ça se reconnaît.\r
+\r
+--En ce cas, reprit Favourite, mort à Blachevelle et vive Tholomyès!\r
+\r
+--Vive Tholomyès! crièrent Dahlia et Zéphine.\r
+\r
+Et elles éclatèrent de rire.\r
+\r
+Fantine rit comme les autres.\r
+\r
+Une heure après, quand elle fut rentrée dans sa chambre, elle pleura.\r
+C'était, nous l'avons dit, son premier amour; elle s'était donnée à ce\r
+Tholomyès comme à un mari, et la pauvre fille avait un enfant.\r

+\r
+Livre quatrième--Confier, c'est quelquefois livrer\r
+\r
+\r
+\r
+\r
+Chapitre I\r
+\r
+Une mère qui en rencontre une autre\r
+\r
+\r
+Il y avait, dans le premier quart de ce siècle, à Montfermeil, près de\r
+Paris, une façon de gargote qui n'existe plus aujourd'hui. Cette gargote\r
+était tenue par des gens appelés Thénardier, mari et femme. Elle était\r
+située dans la ruelle du Boulanger. On voyait au-dessus de la porte une\r
+planche clouée à plat sur le mur. Sur cette planche était peint quelque\r
+chose qui ressemblait à un homme portant sur son dos un autre homme,\r
+lequel avait de grosses épaulettes de général dorées avec de larges\r
+étoiles argentées; des taches rouges figuraient du sang; le reste du\r
+tableau était de la fumée et représentait probablement une bataille. Au\r
+bas on lisait cette inscription: _Au Sergent de Waterloo._\r
+\r
+Rien n'est plus ordinaire qu'un tombereau ou une charrette à la porte\r
+d'une auberge. Cependant le véhicule ou, pour mieux dire, le fragment de\r
+véhicule qui encombrait la rue devant la gargote du Sergent de Waterloo,\r
+un soir du printemps de 1818, eût certainement attiré par sa masse\r
+l'attention d'un peintre qui eût passé là.\r
+\r
+C'était l'avant-train d'un de ces fardiers, usités dans les pays de\r
+forêts, et qui servent à charrier des madriers et des troncs d'arbres.\r
+Cet avant-train se composait d'un massif essieu de fer à pivot où\r
+s'emboîtait un lourd timon, et que supportaient deux roues démesurées.\r
+Tout cet ensemble était trapu, écrasant et difforme. On eût dit l'affût\r
+d'un canon géant. Les ornières avaient donné aux roues, aux jantes, aux\r
+moyeux, à l'essieu et au timon, une couche de vase, hideux badigeonnage\r
+jaunâtre assez semblable à celui dont on orne volontiers les\r
+cathédrales. Le bois disparaissait sous la boue et le fer sous la\r
+rouille. Sous l'essieu pendait en draperie une grosse chaîne digne de\r
+Goliath forçat. Cette chaîne faisait songer, non aux poutres qu'elle\r
+avait fonction de transporter, mais aux mastodontes et aux mammons\r
+qu'elle eût pu atteler; elle avait un air de bagne, mais de bagne\r
+cyclopéen et surhumain, et elle semblait détachée de quelque monstre.\r
+Homère y eût lié Polyphème et Shakespeare Caliban.\r
+\r
+Pourquoi cet avant-train de fardier était-il à cette place dans la rue?\r
+D'abord, pour encombrer la rue; ensuite pour achever de se rouiller. Il\r
+y a dans le vieil ordre social une foule d'institutions qu'on trouve de\r
+la sorte sur son passage en plein air et qui n'ont pas pour être là\r
+d'autres raisons.\r
+\r
+Le centre de la chaîne pendait sous l'essieu assez près de terre, et sur\r
+la courbure, comme sur la corde d'une balançoire, étaient assises et\r
+groupées, ce soir-là, dans un entrelacement exquis, deux petites filles,\r
+l'une d'environ deux ans et demi, l'autre de dix-huit mois, la plus\r
+petite dans les bras de la plus grande. Un mouchoir savamment noué les\r
+empêchait de tomber. Une mère avait vu cette effroyable chaîne, et avait\r
+dit: Tiens! voilà un joujou pour mes enfants.\r
+\r
+Les deux enfants, du reste gracieusement attifées, et avec quelque\r
+recherche, rayonnaient; on eût dit deux roses dans de la ferraille;\r
+leurs yeux étaient un triomphe; leurs fraîches joues riaient. L'une\r
+était châtain, l'autre était brune. Leurs naïfs visages étaient deux\r
+étonnements ravis; un buisson fleuri qui était près de là envoyait aux\r
+passants des parfums qui semblaient venir d'elles; celle de dix-huit\r
+mois montrait son gentil ventre nu avec cette chaste indécence de la\r
+petitesse.\r
+\r
+Au-dessus et autour de ces deux têtes délicates, pétries dans le bonheur\r
+et trempées dans la lumière, le gigantesque avant-train, noir de\r
+rouille, presque terrible, tout enchevêtré de courbes et d'angles\r
+farouches, s'arrondissait comme un porche de caverne. À quelques pas,\r
+accroupie sur le seuil de l'auberge, la mère, femme d'un aspect peu\r
+avenant du reste, mais touchante en ce moment-là, balançait les deux\r
+enfants au moyen d'une longue ficelle, les couvant des yeux de peur\r
+d'accident avec cette expression animale et céleste propre à la\r
+maternité; à chaque va-et-vient, les hideux anneaux jetaient un bruit\r
+strident qui ressemblait à un cri de colère; les petites filles\r
+s'extasiaient, le soleil couchant se mêlait à cette joie, et rien\r
+n'était charmant comme ce caprice du hasard, qui avait fait d'une chaîne\r
+de titans une escarpolette de chérubins.\r
+\r
+Tout en berçant ses deux petites, la mère chantonnait d'une voix fausse\r
+une romance alors célèbre:\r
+\r
+ _Il le faut, disait un guerrier._\r
+\r
+Sa chanson et la contemplation de ses filles l'empêchaient d'entendre et\r
+de voir ce qui se passait dans la rue.\r
+\r
+Cependant quelqu'un s'était approché d'elle, comme elle commençait le\r
+premier couplet de la romance, et tout à coup elle entendit une voix qui\r
+disait très près de son oreille:\r
+\r
+--Vous avez là deux jolis enfants, madame, répondit la mère, continuant\r
+sa romance:\r
+\r
+ _À la belle et tendre Imogine._\r
+\r
+répondit la mère, continuant sa romance, puis elle tourna la tête.\r
+\r
+Une femme était devant elle, à quelques pas. Cette femme, elle aussi,\r
+avait un enfant qu'elle portait dans ses bras.\r
+\r
+Elle portait en outre un assez gros sac de nuit qui semblait fort lourd.\r
+\r
+L'enfant de cette femme était un des plus divins êtres qu'on pût voir.\r
+C'était une fille de deux à trois ans. Elle eût pu jouter avec les deux\r
+autres pour la coquetterie de l'ajustement; elle avait un bavolet de\r
+linge fin, des rubans à sa brassière et de la valenciennes à son bonnet.\r
+Le pli de sa jupe relevée laissait voir sa cuisse blanche, potelée et\r
+ferme. Elle était admirablement rose et bien portante. La belle petite\r
+donnait envie de mordre dans les pommes de ses joues. On ne pouvait rien\r
+dire de ses yeux, sinon qu'ils devaient être très grands et qu'ils\r
+avaient des cils magnifiques. Elle dormait.\r
+\r
+Elle dormait de ce sommeil d'absolue confiance propre à son âge. Les\r
+bras des mères sont faits de tendresse; les enfants y dorment\r
+profondément.\r
+\r
+Quant à la mère, l'aspect en était pauvre et triste. Elle avait la mise\r
+d'une ouvrière qui tend à redevenir paysanne. Elle était jeune.\r
+Était-elle belle? peut-être; mais avec cette mise il n'y paraissait pas.\r
+Ses cheveux, d'où s'échappait une mèche blonde, semblaient fort épais,\r
+mais disparaissaient sévèrement sous une coiffe de béguine, laide,\r
+serrée, étroite, et nouée au menton. Le rire montre les belles dents\r
+quand on en a; mais elle ne riait point. Ses yeux ne semblaient pas être\r
+secs depuis très longtemps. Elle était pâle; elle avait l'air très lasse\r
+et un peu malade; elle regardait sa fille endormie dans ses bras avec\r
+cet air particulier d'une mère qui a nourri son enfant. Un large\r
+mouchoir bleu, comme ceux où se mouchent les invalides, plié en fichu,\r
+masquait lourdement sa taille. Elle avait les mains hâlées et toutes\r
+piquées de taches de rousseur, l'index durci et déchiqueté par\r
+l'aiguille, une Mante brune de laine bourrue, une robe de toile et de\r
+gros souliers. C'était Fantine.\r
+\r
+C'était Fantine. Difficile à reconnaître. Pourtant, à l'examiner\r
+attentivement, elle avait toujours sa beauté. Un pli triste, qui\r
+ressemblait à un commencement d'ironie, ridait sa joue droite. Quant à\r
+sa toilette, cette aérienne toilette de mousseline et de rubans qui\r
+semblait faite avec de la gaîté, de la folie et de la musique, pleine de\r
+grelots et parfumée de lilas, elle s'était évanouie comme ces beaux\r
+givres éclatants qu'on prend pour des diamants au soleil; ils fondent et\r
+laissent la branche toute noire.\r
+\r
+Dix mois s'étaient écoulés depuis «la bonne farce».\r
+\r
+Que s'était-il passé pendant ces dix mois? on le devine.\r
+\r
+Après l'abandon, la gêne. Fantine avait tout de suite perdu de vue\r
+Favourite, Zéphine et Dahlia; le lien, brisé du côté des hommes, s'était\r
+défait du côté des femmes; on les eût bien étonnées, quinze jours après,\r
+si on leur eût dit qu'elles étaient amies; cela n'avait plus de raison\r
+d'être. Fantine était restée seule. Le père de son enfant parti,--hélas!\r
+ces ruptures-là sont irrévocables,--elle se trouva absolument isolée,\r
+avec l'habitude du travail de moins et le goût du plaisir de plus.\r
+Entraînée par sa liaison avec Tholomyès à dédaigner le petit métier\r
+qu'elle savait, elle avait négligé ses débouchés; ils s'étaient fermés.\r
+Nulle ressource. Fantine savait à peine lire et ne savait pas écrire; on\r
+lui avait seulement appris dans son enfance à signer son nom; elle avait\r
+fait écrire par un écrivain public une lettre à Tholomyès, puis une\r
+seconde, puis une troisième. Tholomyès n'avait répondu à aucune. Un\r
+jour, Fantine entendit des commères dire en regardant sa fille:\r
+\r
+--Est-ce qu'on prend ces enfants-là au sérieux? on hausse les épaules de\r
+ces enfants-là!\r
+\r
+Alors elle songea à Tholomyès qui haussait les épaules de son enfant et\r
+qui ne prenait pas cet être innocent au sérieux; et son coeur devint\r
+sombre à l'endroit de cet homme. Quel parti prendre pourtant? Elle ne\r
+savait plus à qui s'adresser. Elle avait commis une faute, mais le fond\r
+de sa nature, on s'en souvient, était pudeur et vertu. Elle sentit\r
+vaguement qu'elle était à la veille de tomber dans la détresse, et de\r
+glisser dans le pire. Il fallait du courage; elle en eut, et se roidit.\r
+L'idée lui vint de retourner dans sa ville natale, à Montreuil-sur-mer.\r
+Là quelqu'un peut-être la connaîtrait et lui donnerait du travail. Oui;\r
+mais il faudrait cacher sa faute. Et elle entrevoyait confusément la\r
+nécessité possible d'une séparation plus douloureuse encore que la\r
+première. Son coeur se serra, mais elle prit sa résolution. Fantine, on\r
+le verra, avait la farouche bravoure de la vie.\r
+\r
+Elle avait déjà vaillamment renoncé à la parure, s'était vêtue de toile,\r
+et avait mis toute sa soie, tous ses chiffons, tous ses rubans et toutes\r
+ses dentelles sur sa fille, seule vanité qui lui restât, et sainte\r
+celle-là. Elle vendit tout ce qu'elle avait, ce qui lui produisit deux\r
+cents francs; ses petites dettes payées, elle n'eut plus que\r
+quatre-vingts francs environ. À vingt-deux ans, par une belle matinée de\r
+printemps, elle quittait Paris, emportant son enfant sur son dos.\r
+Quelqu'un qui les eût vues passer toutes les deux eût pitié. Cette femme\r
+n'avait au monde que cet enfant, et cet enfant n'avait au monde que\r
+cette femme. Fantine avait nourri sa fille; cela lui avait fatigué la\r
+poitrine, et elle toussait un peu.\r
+\r
+Nous n'aurons plus occasion de parler de M. Félix Tholomyès.\r
+Bornons-nous à dire que, vingt ans plus tard, sous le roi\r
+Louis-Philippe, c'était un gros avoué de province, influent et riche,\r
+électeur sage et juré très sévère; toujours homme de plaisir.\r
+\r
+Vers le milieu du jour, après avoir, pour se reposer, cheminé de temps\r
+en temps, moyennant trois ou quatre sous par lieue, dans ce qu'on\r
+appelait alors les Petites Voitures des Environs de Paris, Fantine se\r
+trouvait à Montfermeil, dans la ruelle du Boulanger.\r
+\r
+Comme elle passait devant l'auberge Thénardier, les deux petites filles,\r
+enchantées sur leur escarpolette monstre, avaient été pour elle une\r
+sorte d'éblouissement, et elle s'était arrêtée devant cette vision de\r
+joie.\r
+\r
+Il y a des charmes. Ces deux petites filles en furent un pour cette\r
+mère.\r
+\r
+Elle les considérait, toute émue. La présence des anges est une annonce\r
+de paradis. Elle crut voir au dessus de cette auberge le mystérieux ICI\r
+de la providence. Ces deux petites étaient si évidemment heureuses! Elle\r
+les regardait, elle les admirait, tellement attendrie qu'au moment où la\r
+mère reprenait haleine entre deux vers de sa chanson, elle ne put\r
+s'empêcher de lui dire ce mot qu'on vient de lire:\r
+\r
+--Vous avez là deux jolis enfants, madame.\r
+\r
+Les créatures les plus féroces sont désarmées par la caresse à leurs\r
+petits. La mère leva la tête et remercia, et fit asseoir la passante sur\r
+le banc de la porte, elle-même étant sur le seuil. Les deux femmes\r
+causèrent.\r
+\r
+--Je m'appelle madame Thénardier, dit la mère des deux petites. Nous\r
+tenons cette auberge.\r
+\r
+Puis, toujours à sa romance, elle reprit entre ses dents:\r
+\r
+ _Il le faut, je suis chevalier,_\r
+ _Et je pars pour la Palestine._\r
+\r
+Cette madame Thénardier était une femme rousse, charnue, anguleuse; le\r
+type femme-à-soldat dans toute sa disgrâce. Et, chose bizarre, avec un\r
+air penché qu'elle devait à des lectures romanesques. C'était une\r
+minaudière hommasse. De vieux romans qui se sont éraillés sur des\r
+imaginations de gargotières ont de ces effets-là. Elle était jeune\r
+encore; elle avait à peine trente ans. Si cette femme, qui était\r
+accroupie, se fût tenue droite, peut-être sa haute taille et sa carrure\r
+de colosse ambulant propre aux foires, eussent-elles dès l'abord\r
+effarouché la voyageuse, troublé sa confiance, et fait évanouir ce que\r
+nous avons à raconter. Une personne qui est assise au lieu d'être\r
+debout, les destinées tiennent à cela.\r
+\r
+La voyageuse raconta son histoire, un peu modifiée:\r
+\r
+Qu'elle était ouvrière; que son mari était mort; que le travail lui\r
+manquait à Paris, et qu'elle allait en chercher ailleurs; dans son pays;\r
+qu'elle avait quitté Paris, le matin même, à pied; que, comme elle\r
+portait son enfant, se sentant fatiguée, et ayant rencontré la voiture\r
+de Villemomble, elle y était montée; que de Villemomble elle était venue\r
+à Montfermeil à pied, que la petite avait un peu marché, mais pas\r
+beaucoup, c'est si jeune, et qu'il avait fallu la prendre, et que le\r
+bijou s'était endormi.\r
+\r
+Et sur ce mot elle donna à sa fille un baiser passionné qui la réveilla.\r
+L'enfant ouvrit les yeux, de grands yeux bleus comme ceux de sa mère, et\r
+regarda, quoi? rien, tout, avec cet air sérieux et quelquefois sévère\r
+des petits enfants, qui est un mystère de leur lumineuse innocence\r
+devant nos crépuscules de vertus. On dirait qu'ils se sentent anges et\r
+qu'ils nous savent hommes. Puis l'enfant se mit à rire, et, quoique la\r
+mère la retint, glissa à terre avec l'indomptable énergie d'un petit\r
+être qui veut courir. Tout à coup elle aperçut les deux autres sur leur\r
+balançoire, s'arrêta court, et tira la langue, signe d'admiration.\r
+\r
+La mère Thénardier détacha ses filles, les fit descendre de\r
+l'escarpolette, et dit:\r
+\r
+--Amusez-vous toutes les trois.\r
+\r
+Ces âges-là s'apprivoisent vite, et au bout d'une minute les petites\r
+Thénardier jouaient avec la nouvelle venue à faire des trous dans la\r
+terre, plaisir immense.\r
+\r
+Cette nouvelle venue était très gaie; la bonté de la mère est écrite\r
+dans la gaîté du marmot; elle avait pris un brin de bois qui lui servait\r
+de pelle, et elle creusait énergiquement une fosse bonne pour une\r
+mouche. Ce que fait le fossoyeur devient riant, fait par l'enfant.\r
+\r
+Les deux femmes continuaient de causer.\r
+\r
+--Comment s'appelle votre mioche?\r
+\r
+--Cosette.\r
+\r
+Cosette, lisez Euphrasie. La petite se nommait Euphrasie. Mais\r
+d'Euphrasie la mère avait fait Cosette, par ce doux et gracieux instinct\r
+des mères et du peuple qui change Josefa en Pepita et Françoise en\r
+Sillette. C'est là un genre de dérivés qui dérange et déconcerte toute\r
+la science des étymologistes. Nous avons connu une grand'mère qui avait\r
+réussi à faire de Théodore, Gnon.\r
+\r
+--Quel âge a-t-elle?\r
+\r
+--Elle va sur trois ans.\r
+\r
+--C'est comme mon aînée.\r
+\r
+Cependant les trois petites filles étaient groupées dans une posture\r
+d'anxiété profonde et de béatitude; un événement avait lieu; un gros ver\r
+venait de sortir de terre; et elles avaient peur, et elles étaient en\r
+extase.\r
+\r
+Leurs fronts radieux se touchaient; on eût dit trois têtes dans une\r
+auréole.\r
+\r
+--Les enfants, s'écria la mère Thénardier, comme ça se connaît tout de\r
+suite! les voilà qu'on jurerait trois soeurs!\r
+\r
+Ce mot fut l'étincelle qu'attendait probablement l'autre mère. Elle\r
+saisit la main de la Thénardier, la regarda fixement, et lui dit:\r
+\r
+--Voulez-vous me garder mon enfant?\r
+\r
+La Thénardier eut un de ces mouvements surpris qui ne sont ni le\r
+consentement ni le refus.\r
+\r
+La mère de Cosette poursuivit:\r
+\r
+--Voyez-vous, je ne peux pas emmener ma fille au pays. L'ouvrage ne le\r
+permet pas. Avec un enfant, on ne trouve pas à se placer. Ils sont si\r
+ridicules dans ce pays-là. C'est le bon Dieu qui m'a fait passer devant\r
+votre auberge. Quand j'ai vu vos petites si jolies et si propres et si\r
+contentes, cela m'a bouleversée. J'ai dit: voilà une bonne mère. C'est\r
+ça; ça fera trois soeurs. Et puis, je ne serai pas longtemps à revenir.\r
+Voulez-vous me garder mon enfant?\r
+\r
+--Il faudrait voir, dit la Thénardier.\r
+\r
+--Je donnerais six francs par mois.\r
+\r
+Ici une voix d'homme cria du fond de la gargote:\r
+\r
+--Pas à moins de sept francs. Et six mois payés d'avance.\r
+\r
+--Six fois sept quarante-deux, dit la Thénardier.\r
+\r
+--Je les donnerai, dit la mère.\r
+\r
+--Et quinze francs en dehors pour les premiers frais, ajouta la voix\r
+d'homme.\r
+\r
+--Total cinquante-sept francs, dit la madame Thénardier. Et à travers\r
+ces chiffres, elle chantonnait vaguement:\r
+\r
+_Il le faut, disait un guerrier._\r
+\r
+--Je les donnerai, dit la mère, j'ai quatre-vingts francs. Il me restera\r
+de quoi aller au pays. En allant à pied. Je gagnerai de l'argent là-bas,\r
+et dès que j'en aurai un peu, je reviendrai chercher l'amour.\r
+\r
+La voix d'homme reprit:\r
+\r
+--La petite a un trousseau?\r
+\r
+--C'est mon mari, dit la Thénardier.\r
+\r
+--Sans doute elle a un trousseau, le pauvre trésor. J'ai bien vu que\r
+c'était votre mari. Et un beau trousseau encore! un trousseau insensé.\r
+Tout par douzaines; et des robes de soie comme une dame. Il est là dans\r
+mon sac de nuit.\r
+\r
+--Il faudra le donner, repartit la voix d'homme.\r
+\r
+--Je crois bien que je le donnerai! dit la mère. Ce serait cela qui\r
+serait drôle si je laissais ma fille toute nue!\r
+\r
+La face du maître apparut.\r
+\r
+--C'est bon, dit-il.\r
+\r
+Le marché fut conclu. La mère passa la nuit à l'auberge, donna son\r
+argent et laissa son enfant, renoua son sac de nuit dégonflé du\r
+trousseau et léger désormais, et partit le lendemain matin, comptant\r
+revenir bientôt. On arrange tranquillement ces départs-là, mais ce sont\r
+des désespoirs.\r
+\r
+Une voisine des Thénardier rencontra cette mère comme elle s'en allait,\r
+et s'en revint en disant:\r
+\r
+--Je viens de voir une femme qui pleure dans la rue, que c'est un\r
+déchirement.\r
+\r
+Quand la mère de Cosette fut partie, l'homme dit à la femme:\r
+\r
+--Cela va me payer mon effet de cent dix francs qui échoit demain. Il me\r
+manquait cinquante francs. Sais-tu que j'aurais eu l'huissier et un\r
+protêt? Tu as fait là une bonne souricière avec tes petites.\r
+\r
+--Sans m'en douter, dit la femme.\r

+Chapitre II\r
+\r
+Première esquisse de deux figures louches\r
+\r
+\r
+La souris prise était bien chétive; mais le chat se réjouit même d'une\r
+souris maigre. Qu'était-ce que les Thénardier?\r
+\r
+Disons-en un mot dès à présent. Nous compléterons le croquis plus tard.\r
+\r
+Ces êtres appartenaient à cette classe bâtarde composée de gens\r
+grossiers parvenus et de gens intelligents déchus, qui est entre la\r
+classe dite moyenne et la classe dite inférieure, et qui combine\r
+quelques-uns des défauts de la seconde avec presque tous les vices de la\r
+première, sans avoir le généreux élan de l'ouvrier ni l'ordre honnête du\r
+bourgeois.\r
+\r
+C'étaient de ces natures naines qui, si quelque feu sombre les chauffe\r
+par hasard, deviennent facilement monstrueuses. Il y avait dans la femme\r
+le fond d'une brute et dans l'homme l'étoffe d'un gueux. Tous deux\r
+étaient au plus haut degré susceptibles de l'espèce de hideux progrès\r
+qui se fait dans le sens du mal. Il existe des âmes écrevisses reculant\r
+continuellement vers les ténèbres, rétrogradant dans la vie plutôt\r
+qu'elles n'y avancent, employant l'expérience à augmenter leur\r
+difformité, empirant sans cesse, et s'empreignant de plus en plus d'une\r
+noirceur croissante. Cet homme et cette femme étaient de ces âmes-là.\r
+\r
+Le Thénardier particulièrement était gênant pour le physionomiste. On\r
+n'a qu'à regarder certains hommes pour s'en défier, on les sent\r
+ténébreux à leurs deux extrémités. Ils sont inquiets derrière eux et\r
+menaçants devant eux. Il y a en eux de l'inconnu. On ne peut pas plus\r
+répondre de ce qu'ils ont fait que de ce qu'ils feront. L'ombre qu'ils\r
+ont dans le regard les dénonce. Rien qu'en les entendant dire un mot ou\r
+qu'en les voyant faire un geste on entrevoit de sombres secrets dans\r
+leur passé et de sombres mystères dans leur avenir.\r
+\r
+Ce Thénardier, s'il fallait l'en croire, avait été soldat; sergent,\r
+disait-il; il avait fait probablement la campagne de 1815, et s'était\r
+même comporté assez bravement, à ce qu'il paraît. Nous verrons plus tard\r
+ce qu'il en était. L'enseigne de son cabaret était une allusion à l'un\r
+de ses faits d'armes. Il l'avait peinte lui-même, car il savait faire un\r
+peu de tout; mal.\r
+\r
+C'était l'époque où l'antique roman classique, qui, après avoir été\r
+_Clélie_, n'était plus que _Lodoïska_, toujours noble, mais de plus en\r
+plus vulgaire, tombé de mademoiselle de Scudéri à madame\r
+Barthélemy-Hadot, et de madame de Lafayette à madame Bournon-Malarme,\r
+incendiait l'âme aimante des portières de Paris et ravageait même un peu\r
+la banlieue. Madame Thénardier était juste assez intelligente pour lire\r
+ces espèces de livres. Elle s'en nourrissait. Elle y noyait ce qu'elle\r
+avait de cervelle; cela lui avait donné, tant qu'elle avait été très\r
+jeune, et même un peu plus tard, une sorte d'attitude pensive près de\r
+son mari, coquin d'une certaine profondeur, ruffian lettré à la\r
+grammaire près, grossier et fin en même temps, mais, en fait de\r
+sentimentalisme, lisant Pigault-Lebrun, et pour «tout ce qui touche le\r
+sexe», comme il disait dans son jargon, butor correct et sans mélange.\r
+Sa femme avait quelque douze ou quinze ans de moins que lui. Plus tard,\r
+quand les cheveux romanesquement pleureurs commencèrent à grisonner,\r
+quand la Mégère se dégagea de la Paméla, la Thénardier ne fut plus\r
+qu'une grosse méchante femme ayant savouré des romans bêtes. Or on ne\r
+lit pas impunément des niaiseries. Il en résulta que sa fille aînée se\r
+nomma Eponine. Quant à la cadette, la pauvre petite faillit se nommer\r
+Gulnare; elle dut à je ne sais quelle heureuse diversion faite par un\r
+roman de Ducray-Duminil, de ne s'appeler qu'Azelma.\r
+\r
+Au reste, pour le dire en passant, tout n'est pas ridicule et\r
+superficiel dans cette curieuse époque à laquelle nous faisons ici\r
+allusion, et qu'on pourrait appeler l'anarchie des noms de baptême. À\r
+côté de l'élément romanesque, que nous venons d'indiquer, il y a le\r
+symptôme social. Il n'est pas rare aujourd'hui que le garçon bouvier se\r
+nomme Arthur, Alfred ou Alphonse, et que le vicomte--s'il y a encore des\r
+vicomtes--se nomme Thomas, Pierre ou Jacques. Ce déplacement qui met le\r
+nom «élégant» sur le plébéien et le nom campagnard sur l'aristocrate\r
+n'est autre chose qu'un remous d'égalité. L'irrésistible pénétration du\r
+souffle nouveau est là comme en tout. Sous cette discordance apparente,\r
+il y a une chose grande et profonde: la révolution française.\r

+\r
+\r
+Chapitre III\r
+\r
+L'Alouette\r
+\r
+\r
+Il ne suffit pas d'être méchant pour prospérer. La gargote allait mal.\r
+\r
+Grâce aux cinquante-sept francs de la voyageuse, Thénardier avait pu\r
+éviter un protêt et faire honneur à sa signature. Le mois suivant ils\r
+eurent encore besoin d'argent; la femme porta à Paris et engagea au\r
+Mont-de-Piété le trousseau de Cosette pour une somme de soixante francs.\r
+Dès que cette somme fut dépensée, les Thénardier s'accoutumèrent à ne\r
+plus voir dans la petite fille qu'un enfant qu'ils avaient chez eux par\r
+charité, et la traitèrent en conséquence. Comme elle n'avait plus de\r
+trousseau, on l'habilla des vieilles jupes et des vieilles chemises des\r
+petites Thénardier, c'est-à-dire de haillons.\r
+\r
+On la nourrit des restes de tout le monde, un peu mieux que le chien et\r
+un peu plus mal que le chat. Le chat et le chien étaient du reste ses\r
+commensaux habituels; Cosette mangeait avec eux sous la table dans une\r
+écuelle de bois pareille à la leur. La mère qui s'était fixée, comme on\r
+le verra plus tard, à Montreuil-sur-mer, écrivait, ou, pour mieux dire,\r
+faisait écrire tous les mois afin d'avoir des nouvelles de son enfant.\r
+Les Thénardier répondaient invariablement: Cosette est à merveille. Les\r
+six premiers mois révolus, la mère envoya sept francs pour le septième\r
+mois, et continua assez exactement ses envois de mois en mois. L'année\r
+n'était pas finie que le Thénardier dit:\r
+\r
+--Une belle grâce qu'elle nous fait là! que veut-elle que nous fassions\r
+avec ses sept francs?\r
+\r
+Et il écrivit pour exiger douze francs. La mère, à laquelle ils\r
+persuadaient que son enfant était heureuse "et venait bien", se soumit\r
+et envoya les douze francs.\r
+\r
+Certaines natures ne peuvent aimer d'un côté sans haïr de l'autre. La\r
+mère Thénardier aimait passionnément ses deux filles à elle, ce qui fit\r
+qu'elle détesta l'étrangère. Il est triste de songer que l'amour d'une\r
+mère peut avoir de vilains aspects. Si peu de place que Cosette tînt\r
+chez elle, il lui semblait que cela était pris aux siens, et que cette\r
+petite diminuait l'air que ses filles respiraient. Cette femme, comme\r
+beaucoup de femmes de sa sorte, avait une somme de caresses et une somme\r
+de coups et d'injures à dépenser chaque jour. Si elle n'avait pas eu\r
+Cosette, il est certain que ses filles, tout idolâtrées qu'elles\r
+étaient, auraient tout reçu; mais l'étrangère leur rendit le service de\r
+détourner les coups sur elle. Ses filles n'eurent que les caresses.\r
+Cosette ne faisait pas un mouvement qui ne fît pleuvoir sur sa tête une\r
+grêle de châtiments violents et immérités. Doux être faible qui ne\r
+devait rien comprendre à ce monde ni à Dieu, sans cesse punie, grondée,\r
+rudoyée, battue et voyant à côté d'elle deux petites créatures comme\r
+elle, qui vivaient dans un rayon d'aurore!\r
+\r
+La Thénardier étant méchante pour Cosette, Éponine et Azelma furent\r
+méchantes. Les enfants, à cet âge, ne sont que des exemplaires de la\r
+mère. Le format est plus petit, voilà tout.\r
+\r
+Une année s'écoula, puis une autre.\r
+\r
+On disait dans le village:\r
+\r
+--Ces Thénardier sont de braves gens. Ils ne sont pas riches, et ils\r
+élèvent un pauvre enfant qu'on leur a abandonné chez eux!\r
+\r
+On croyait Cosette oubliée par sa mère.\r
+\r
+Cependant le Thénardier, ayant appris par on ne sait quelles voies\r
+obscures que l'enfant était probablement bâtard et que la mère ne\r
+pouvait l'avouer, exigea quinze francs par mois, disant que «la\r
+créature» grandissait et «_mangeait_», et menaçant de la renvoyer.\r
+«Quelle ne m'embête pas! s'écriait-il, je lui bombarde son mioche tout\r
+au beau milieu de ses cachotteries. Il me faut de l'augmentation.» La\r
+mère paya les quinze francs.\r
+\r
+D'année en année, l'enfant grandit, et sa misère aussi.\r
+\r
+Tant que Cosette fut toute petite, elle fut le souffre-douleur des deux\r
+autres enfants; dès qu'elle se mit à se développer un peu, c'est-à-dire\r
+avant même qu'elle eût cinq ans, elle devint la servante de la maison.\r
+\r
+Cinq ans, dira-t-on, c'est invraisemblable. Hélas, c'est vrai. La\r
+souffrance sociale commence à tout âge.\r
+\r
+N'avons-nous pas vu, récemment, le procès d'un nommé Dumolard, orphelin\r
+devenu bandit, qui, dès l'âge de cinq ans, disent les documents\r
+officiels, étant seul au monde «travaillait pour vivre, et volait.»\r
+\r
+On fit faire à Cosette les commissions, balayer les chambres, la cour,\r
+la rue, laver la vaisselle, porter même des fardeaux. Les Thénardier se\r
+crurent d'autant plus autorisés à agir ainsi que la mère qui était\r
+toujours à Montreuil-sur-mer commença à mal payer. Quelques mois\r
+restèrent en souffrance.\r
+\r
+Si cette mère fût revenue à Montfermeil au bout de ces trois années,\r
+elle n'eût point reconnu son enfant. Cosette, si jolie et si fraîche à\r
+son arrivée dans cette maison, était maintenant maigre et blême. Elle\r
+avait je ne sais quelle allure inquiète. Sournoise! disaient les\r
+Thénardier.\r
+\r
+L'injustice l'avait faite hargneuse et la misère l'avait rendue laide.\r
+Il ne lui restait plus que ses beaux yeux qui faisaient peine, parce\r
+que, grands comme ils étaient, il semblait qu'on y vît une plus grande\r
+quantité de tristesse.\r
+\r
+C'était une chose navrante de voir, l'hiver, ce pauvre enfant, qui\r
+n'avait pas encore six ans, grelottant sous de vieilles loques de toile\r
+trouées, balayer la rue avant le jour avec un énorme balai dans ses\r
+petites mains rouges et une larme dans ses grands yeux.\r
+\r
+Dans le pays on l'appelait l'Alouette. Le peuple, qui aime les figures,\r
+s'était plu à nommer de ce nom ce petit être pas plus gros qu'un oiseau,\r
+tremblant, effarouché et frissonnant, éveillé le premier chaque matin\r
+dans la maison et dans le village, toujours dans la rue ou dans les\r
+champs avant l'aube. Seulement la pauvre Alouette ne chantait jamais.\r

+Chapitre I\r
+\r
+Histoire d'un progrès dans les verroteries noires\r
+\r
+\r
+Cette mère cependant qui, au dire des gens de Montfermeil, semblait\r
+avoir abandonné son enfant, que devenait-elle? où était-elle? que\r
+faisait-elle?\r
+\r
+Après avoir laissé sa petite Cosette aux Thénardier, elle avait continué\r
+son chemin et était arrivée à Montreuil-sur-mer.\r
+\r
+C'était, on se le rappelle, en 1818.\r
+\r
+Fantine avait quitté sa province depuis une dizaine d'années.\r
+Montreuil-sur-mer avait changé d'aspect. Tandis que Fantine descendait\r
+lentement de misère en misère, sa ville natale avait prospéré.\r
+\r
+Depuis deux ans environ, il s'y était accompli un de ces faits\r
+industriels qui sont les grands événements des petits pays.\r
+\r
+Ce détail importe, et nous croyons utile de le développer; nous dirions\r
+presque, de le souligner.\r
+\r
+De temps immémorial, Montreuil-sur-mer avait pour industrie spéciale\r
+l'imitation des jais anglais et des verroteries noires d'Allemagne.\r
+Cette industrie avait toujours végété, à cause de la cherté des matières\r
+premières qui réagissait sur la main-d'oeuvre. Au moment où Fantine\r
+revint à Montreuil-sur-mer, une transformation inouïe s'était opérée\r
+dans cette production des «articles noirs». Vers la fin de 1815, un\r
+homme, un inconnu, était venu s'établir dans la ville et avait eu l'idée\r
+de substituer, dans cette fabrication, la gomme laque à la résine et,\r
+pour les bracelets en particulier, les coulants en tôle simplement\r
+rapprochée aux coulants en tôle soudée. Ce tout petit changement avait\r
+été une révolution.\r
+\r
+Ce tout petit changement en effet avait prodigieusement réduit le prix\r
+de la matière première, ce qui avait permis, premièrement, d'élever le\r
+prix de la main-d'oeuvre, bienfait pour le pays; deuxièmement,\r
+d'améliorer la fabrication, avantage pour le consommateur;\r
+troisièmement, de vendre à meilleur marché tout en triplant le bénéfice,\r
+profit pour le manufacturier.\r
+\r
+Ainsi pour une idée trois résultats.\r
+\r
+En moins de trois ans, l'auteur de ce procédé était devenu riche, ce qui\r
+est bien, et avait tout fait riche autour de lui, ce qui est mieux. Il\r
+était étranger au département. De son origine, on ne savait rien; de ses\r
+commencements, peu de chose.\r
+\r
+On contait qu'il était venu dans la ville avec fort peu d'argent,\r
+quelques centaines de francs tout au plus.\r
+\r
+C'est de ce mince capital, mis au service d'une idée ingénieuse, fécondé\r
+par l'ordre et par la pensée, qu'il avait tiré sa fortune et la fortune\r
+de tout ce pays.\r
+\r
+À son arrivée à Montreuil-sur-mer, il n'avait que les vêtements, la\r
+tournure et le langage d'un ouvrier.\r
+\r
+Il paraît que, le jour même où il faisait obscurément son entrée dans la\r
+petite ville de Montreuil-sur-mer, à la tombée d'un soir de décembre, le\r
+sac au dos et le bâton d'épine à la main, un gros incendie venait\r
+d'éclater à la maison commune. Cet homme s'était jeté dans le feu, et\r
+avait sauvé, au péril de sa vie, deux enfants qui se trouvaient être\r
+ceux du capitaine de gendarmerie; ce qui fait qu'on n'avait pas songé à\r
+lui demander son passeport. Depuis lors, on avait su son nom. Il\r
+s'appelait le _père Madeleine_.\r
+\r
+\r
+\r
+\r
+Chapitre II\r
+\r
+M. Madeleine\r
+\r
+\r
+C'était un homme d'environ cinquante ans, qui avait l'air préoccupé et\r
+qui était bon. Voilà tout ce qu'on en pouvait dire.\r
+\r
+Grâce aux progrès rapides de cette industrie qu'il avait si\r
+admirablement remaniée, Montreuil-sur-mer était devenu un centre\r
+d'affaires considérable. L'Espagne, qui consomme beaucoup de jais noir,\r
+y commandait chaque année des achats immenses. Montreuil-sur-mer, pour\r
+ce commerce, faisait presque concurrence à Londres et à Berlin. Les\r
+bénéfices du père Madeleine étaient tels que, dès la deuxième année, il\r
+avait pu bâtir une grande fabrique dans laquelle il y avait deux vastes\r
+ateliers, l'un pour les hommes, l'autre pour les femmes. Quiconque avait\r
+faim pouvait s'y présenter, et était sûr de trouver là de l'emploi et du\r
+pain. Le père Madeleine demandait aux hommes de la bonne volonté, aux\r
+femmes des moeurs pures, à tous de la probité. Il avait divisé les\r
+ateliers afin de séparer les sexes et que les filles et les femmes\r
+pussent rester sages. Sur ce point, il était inflexible. C'était le seul\r
+où il fût en quelque sorte intolérant. Il était d'autant plus fondé à\r
+cette sévérité que, Montreuil-sur-mer étant une ville de garnison, les\r
+occasions de corruption abondaient. Du reste sa venue avait été un\r
+bienfait, et sa présence était une providence. Avant l'arrivée du père\r
+Madeleine, tout languissait dans le pays; maintenant tout y vivait de la\r
+vie saine du travail. Une forte circulation échauffait tout et pénétrait\r
+partout. Le chômage et la misère étaient inconnus. Il n'y avait pas de\r
+poche si obscure où il n'y eût un peu d'argent, pas de logis si pauvre\r
+où il n'y eût un peu de joie.\r
+\r
+Le père Madeleine employait tout le monde. Il n'exigeait qu'une chose:\r
+soyez honnête homme! soyez honnête fille!\r
+\r
+Comme nous l'avons dit, au milieu de cette activité dont il était la\r
+cause et le pivot, le père Madeleine faisait sa fortune, mais, chose\r
+assez singulière dans un simple homme de commerce, il ne paraissait\r
+point que ce fût là son principal souci. Il semblait qu'il songeât\r
+beaucoup aux autres et peu à lui. En 1820, on lui connaissait une somme\r
+de six cent trente mille francs placée à son nom chez Laffitte; mais\r
+avant de se réserver ces six cent trente mille francs, il avait dépensé\r
+plus d'un million pour la ville et pour les pauvres.\r
+\r
+L'hôpital était mal doté; il y avait fondé dix lits. Montreuil-sur-mer\r
+est divisé en ville haute et ville basse. La ville basse, qu'il\r
+habitait, n'avait qu'une école, méchante masure qui tombait en ruine; il\r
+en avait construit deux, une pour les filles, l'autre pour les garçons.\r
+Il allouait de ses deniers aux deux instituteurs une indemnité double de\r
+leur maigre traitement officiel, et un jour, à quelqu'un qui s'en\r
+étonnait, il dit: «Les deux premiers fonctionnaires de l'état, c'est la\r
+nourrice et le maître d'école.» Il avait créé à ses frais une salle\r
+d'asile, chose alors presque inconnue en France, et une caisse de\r
+secours pour les ouvriers vieux et infirmes. Sa manufacture étant un\r
+centre, un nouveau quartier où il y avait bon nombre de familles\r
+indigentes avait rapidement surgi autour de lui; il y avait établi une\r
+pharmacie gratuite.\r
+\r
+Dans les premiers temps, quand on le vit commencer, les bonnes âmes\r
+dirent: C'est un gaillard qui veut s'enrichir. Quand on le vit enrichir\r
+le pays avant de s'enrichir lui-même, les mêmes bonnes âmes dirent:\r
+C'est un ambitieux. Cela semblait d'autant plus probable que cet homme\r
+était religieux, et même pratiquait dans une certaine mesure, chose fort\r
+bien vue à cette époque. Il allait régulièrement entendre une basse\r
+messe tous les dimanches. Le député local, qui flairait partout des\r
+concurrences, ne tarda pas à s'inquiéter de cette religion. Ce député,\r
+qui avait été membre du corps législatif de l'empire, partageait les\r
+idées religieuses d'un père de l'oratoire connu sous le nom de Fouché,\r
+duc d'Otrante, dont il avait été la créature et l'ami. À huis clos il\r
+riait de Dieu doucement. Mais quand il vit le riche manufacturier\r
+Madeleine aller à la basse messe de sept heures, il entrevit un candidat\r
+possible, et résolut de le dépasser; il prit un confesseur jésuite et\r
+alla à la grand'messe et à vêpres. L'ambition en ce temps-là était, dans\r
+l'acception directe du mot, une course au clocher. Les pauvres\r
+profitèrent de cette terreur comme le bon Dieu, car l'honorable député\r
+fonda aussi deux lits à l'hôpital; ce qui fit douze.\r
+\r
+Cependant en 1819 le bruit se répandit un matin dans la ville que, sur\r
+la présentation de M. le préfet, et en considération des services rendus\r
+au pays, le père Madeleine allait être nommé par le roi maire de\r
+Montreuil-sur-mer. Ceux qui avaient déclaré ce nouveau venu «un\r
+ambitieux», saisirent avec transport cette occasion que tous les hommes\r
+souhaitent de s'écrier: «Là! qu'est-ce que nous avions dit?» Tout\r
+Montreuil-sur-mer fut en rumeur. Le bruit était fondé. Quelques jours\r
+après, la nomination parut dans _le Moniteur_. Le lendemain, le père\r
+Madeleine refusa.\r
+\r
+Dans cette même année 1819, les produits du nouveau procédé inventé par\r
+Madeleine figurèrent à l'exposition de l'industrie; sur le rapport du\r
+jury, le roi nomma l'inventeur chevalier de la Légion d'honneur.\r
+Nouvelle rumeur dans la petite ville. Eh bien! c'est la croix qu'il\r
+voulait! Le père Madeleine refusa la croix.\r
+\r
+Décidément cet homme était une énigme. Les bonnes âmes se tirèrent\r
+d'affaire en disant: Après tout, c'est une espèce d'aventurier.\r
+\r
+On l'a vu, le pays lui devait beaucoup, les pauvres lui devaient tout;\r
+il était si utile qu'il avait bien fallu qu'on finît par l'honorer, et\r
+il était si doux qu'il avait bien fallu qu'on finît par l'aimer; ses\r
+ouvriers en particulier l'adoraient, et il portait cette adoration avec\r
+une sorte de gravité mélancolique. Quand il fut constaté riche, «les\r
+personnes de la société» le saluèrent, et on l'appela dans la ville\r
+monsieur Madeleine; ses ouvriers et les enfants continuèrent de\r
+l'appeler _le père Madeleine_, et c'était la chose qui le faisait le\r
+mieux sourire. À mesure qu'il montait, les invitations pleuvaient sur\r
+lui. «La société» le réclamait. Les petits salons guindés de\r
+Montreuil-sur-mer qui, bien entendu, se fussent dans les premiers temps\r
+fermés à l'artisan, s'ouvrirent à deux battants au millionnaire. On lui\r
+fit mille avances. Il refusa.\r
+\r
+Cette fois encore les bonnes âmes ne furent point empêchées.\r
+\r
+--C'est un homme ignorant et de basse éducation. On ne sait d'où cela\r
+sort. Il ne saurait pas se tenir dans le monde. Il n'est pas du tout\r
+prouvé qu'il sache lire.\r
+\r
+Quand on l'avait vu gagner de l'argent, on avait dit: c'est un marchand.\r
+Quand on l'avait vu semer son argent, on avait dit: c'est un ambitieux.\r
+Quand on l'avait vu repousser les honneurs, on avait dit: c'est un\r
+aventurier. Quand on le vit repousser le monde, on dit: c'est une brute.\r
+\r
+En 1820, cinq ans après son arrivée à Montreuil-sur-mer, les services\r
+qu'il avait rendus au pays étaient si éclatants, le voeu de la contrée\r
+fut tellement unanime, que le roi le nomma de nouveau maire de la ville.\r
+Il refusa encore, mais le préfet résista à son refus, tous les notables\r
+vinrent le prier, le peuple en pleine rue le suppliait, l'insistance fut\r
+si vive qu'il finit par accepter. On remarqua que ce qui parut surtout\r
+le déterminer, ce fut l'apostrophe presque irritée d'une vieille femme\r
+du peuple qui lui cria du seuil de sa porte avec humeur: _Un bon maire,\r
+c'est utile. Est-ce qu'on recule devant du bien qu'on peut faire?_\r
+\r
+Ce fut là la troisième phase de son ascension. Le père Madeleine était\r
+devenu monsieur Madeleine, monsieur Madeleine devint monsieur le maire.\r
+\r
+\r
+\r
+\r
+Chapitre III\r
+\r
+Sommes déposées chez Laffitte\r
+\r
+\r
+Du reste, il était demeuré aussi simple que le premier jour. Il avait\r
+les cheveux gris, l'oeil sérieux, le teint hâlé d'un ouvrier, le visage\r
+pensif d'un philosophe. Il portait habituellement un chapeau à bords\r
+larges et une longue redingote de gros drap, boutonnée jusqu'au menton.\r
+Il remplissait ses fonctions de maire, mais hors de là il vivait\r
+solitaire. Il parlait à peu de monde. Il se dérobait aux politesses,\r
+saluait de côté, s'esquivait vite, souriait pour se dispenser de causer,\r
+donnait pour se dispenser de sourire. Les femmes disaient de lui: Quel\r
+bon ours! Son plaisir était de se promener dans les champs.\r
+\r
+Il prenait ses repas toujours seul, avec un livre ouvert devant lui où\r
+il lisait. Il avait une petite bibliothèque bien faite. Il aimait les\r
+livres; les livres sont des amis froids et sûrs. À mesure que le loisir\r
+lui venait avec la fortune, il semblait qu'il en profitât pour cultiver\r
+son esprit. Depuis qu'il était à Montreuil-sur-mer, on remarquait que\r
+d'année en année son langage devenait plus poli, plus choisi et plus\r
+doux.\r
+\r
+Il emportait volontiers un fusil dans ses promenades, mais il s'en\r
+servait rarement. Quand cela lui arrivait par aventure, il avait un tir\r
+infaillible qui effrayait. Jamais il ne tuait un animal inoffensif.\r
+Jamais il ne tirait un petit oiseau. Quoiqu'il ne fût plus jeune, on\r
+contait qu'il était d'une force prodigieuse. Il offrait un coup de main\r
+à qui en avait besoin, relevait un cheval, poussait à une roue\r
+embourbée, arrêtait par les cornes un taureau échappé. Il avait toujours\r
+ses poches pleines de monnaie en sortant et vides en rentrant. Quand il\r
+passait dans un village, les marmots déguenillés couraient joyeusement\r
+après lui et l'entouraient comme une nuée de moucherons.\r
+\r
+On croyait deviner qu'il avait dû vivre jadis de la vie des champs, car\r
+il avait toutes sortes de secrets utiles qu'il enseignait aux paysans.\r
+Il leur apprenait à détruire la teigne des blés en aspergeant le grenier\r
+et en inondant les fentes du plancher d'une dissolution de sel commun,\r
+et à chasser les charançons en suspendant partout, aux murs et aux\r
+toits, dans les héberges et dans les maisons, de l'orviot en fleur. Il\r
+avait des "recettes" pour extirper d'un champ la luzette, la nielle, la\r
+vesce, la gaverolle, la queue-de-renard, toutes les herbes parasites qui\r
+mangent le blé. Il défendait une lapinière contre les rats rien qu'avec\r
+l'odeur d'un petit cochon de Barbarie qu'il y mettait. Un jour il voyait\r
+des gens du pays très occupés à arracher des orties. Il regarda ce tas\r
+de plantes déracinées et déjà desséchées, et dit:\r
+\r
+--C'est mort. Cela serait pourtant bon si l'on savait s'en servir. Quand\r
+l'ortie est jeune, la feuille est un légume excellent; quand elle\r
+vieillit, elle a des filaments et des fibres comme le chanvre et le lin.\r
+La toile d'ortie vaut la toile de chanvre. Hachée, l'ortie est bonne\r
+pour la volaille; broyée, elle est bonne pour les bêtes à cornes. La\r
+graine de l'ortie mêlée au fourrage donne du luisant au poil des\r
+animaux; la racine mêlée au sel produit une belle couleur jaune. C'est\r
+du reste un excellent foin qu'on peut faucher deux fois. Et que faut-il\r
+à l'ortie? Peu de terre, nul soin, nulle culture. Seulement la graine\r
+tombe à mesure qu'elle mûrit, et est difficile à récolter. Voilà tout.\r
+Avec quelque peine qu'on prendrait, l'ortie serait utile; on la néglige,\r
+elle devient nuisible. Alors on la tue. Que d'hommes ressemblent à\r
+l'ortie!\r
+\r
+Il ajouta après un silence:\r
+\r
+--Mes amis, retenez ceci, il n'y a ni mauvaises herbes ni mauvais\r
+hommes. Il n'y a que de mauvais cultivateurs.\r
+\r
+Les enfants l'aimaient encore parce qu'il savait faire de charmants\r
+petits ouvrages avec de la paille et des noix de coco.\r
+\r
+Quand il voyait la porte d'une église tendue de noir, il entrait; il\r
+recherchait un enterrement comme d'autres recherchent un baptême. Le\r
+veuvage et le malheur d'autrui l'attiraient à cause de sa grande\r
+douceur; il se mêlait aux amis en deuil, aux familles vêtues de noir,\r
+aux prêtres gémissant autour d'un cercueil. Il semblait donner\r
+volontiers pour texte à ses pensées ces psalmodies funèbres pleines de\r
+la vision d'un autre monde. L'oeil au ciel, il écoutait, avec une sorte\r
+d'aspiration vers tous les mystères de l'infini, ces voix tristes qui\r
+chantent sur le bord de l'abîme obscur de la mort.\r
+\r
+Il faisait une foule de bonnes actions en se cachant comme on se cache\r
+pour les mauvaises. Il pénétrait à la dérobée, le soir, dans les\r
+maisons; il montait furtivement des escaliers. Un pauvre diable, en\r
+rentrant dans son galetas, trouvait que sa porte avait été ouverte,\r
+quelquefois même forcée, dans son absence. Le pauvre homme se récriait:\r
+quelque malfaiteur est venu! Il entrait, et la première chose qu'il\r
+voyait, c'était une pièce d'or oubliée sur un meuble. "Le malfaiteur"\r
+qui était venu, c'était le père Madeleine.\r
+\r
+Il était affable et triste. Le peuple disait: «Voilà un homme riche qui\r
+n'a pas l'air fier. Voilà un homme heureux qui n'a pas l'air content.»\r
+\r
+Quelques-uns prétendaient que c'était un personnage mystérieux, et\r
+affirmaient qu'on n'entrait jamais dans sa chambre, laquelle était une\r
+vraie cellule d'anachorète meublée de sabliers ailés et enjolivée de\r
+tibias en croix et de têtes de mort. Cela se disait beaucoup, si bien\r
+que quelques jeunes femmes élégantes et malignes de Montreuil-sur-mer\r
+vinrent chez lui un jour, et lui demandèrent:\r
+\r
+--Monsieur le maire, montrez-nous donc votre chambre. On dit que c'est\r
+une grotte.\r
+\r
+Il sourit, et les introduisit sur-le-champ dans cette «grotte». Elles\r
+furent bien punies de leur curiosité. C'était une chambre garnie tout\r
+bonnement de meubles d'acajou assez laids comme tous les meubles de ce\r
+genre et tapissée de papier à douze sous. Elles n'y purent rien\r
+remarquer que deux flambeaux de forme vieillie qui étaient sur la\r
+cheminée et qui avaient l'air d'être en argent, «car ils étaient\r
+contrôlés». Observation pleine de l'esprit des petites villes.\r
+\r
+On n'en continua pas moins de dire que personne ne pénétrait dans cette\r
+chambre et que c'était une caverne d'ermite, un rêvoir, un trou, un\r
+tombeau.\r
+\r
+On se chuchotait aussi qu'il avait des sommes «immenses» déposées chez\r
+Laffitte, avec cette particularité qu'elles étaient toujours à sa\r
+disposition immédiate, de telle sorte, ajoutait-on, que M. Madeleine\r
+pourrait arriver un matin chez Laffitte, signer un reçu et emporter ses\r
+deux ou trois millions en dix minutes. Dans la réalité ces «deux ou\r
+trois millions» se réduisaient, nous l'avons dit, à six cent trente ou\r
+quarante mille francs.\r
+\r

+\r
+Chapitre IV\r
+\r
+M. Madeleine en deuil\r
+\r
+\r
+Au commencement de 1821, les journaux annoncèrent la mort de M. Myriel,\r
+évêque de Digne, «surnommé _monseigneur Bienvenu_», et trépassé en odeur\r
+de sainteté à l'âge de quatre-vingt-deux ans.\r
+\r
+L'évêque de Digne, pour ajouter ici un détail que les journaux omirent,\r
+était, quand il mourut, depuis plusieurs années aveugle, et content\r
+d'être aveugle, sa soeur étant près de lui.\r
+\r
+Disons-le en passant, être aveugle et être aimé, c'est en effet, sur\r
+cette terre où rien n'est complet, une des formes les plus étrangement\r
+exquises du bonheur. Avoir continuellement à ses côtés une femme, une\r
+fille, une soeur, un être charmant, qui est là parce que vous avez\r
+besoin d'elle et parce qu'elle ne peut se passer de vous, se savoir\r
+indispensable à qui nous est nécessaire, pouvoir incessamment mesurer\r
+son affection à la quantité de présence qu'elle nous donne, et se dire:\r
+puisqu'elle me consacre tout son temps, c'est que j'ai tout son coeur;\r
+voir la pensée à défaut de la figure, constater la fidélité d'un être\r
+dans l'éclipse du monde, percevoir le frôlement d'une robe comme un\r
+bruit d'ailes, l'entendre aller et venir, sortir, rentrer, parler,\r
+chanter, et songer qu'on est le centre de ces pas, de cette parole, de\r
+ce chant, manifester à chaque minute sa propre attraction, se sentir\r
+d'autant plus puissant qu'on est plus infirme, devenir dans l'obscurité,\r
+et par l'obscurité, l'astre autour duquel gravite cet ange, peu de\r
+félicités égalent celle-là. Le suprême bonheur de la vie, c'est la\r
+conviction qu'on est aimé; aimé pour soi-même, disons mieux, aimé malgré\r
+soi-même; cette conviction, l'aveugle l'a. Dans cette détresse, être\r
+servi, c'est être caressé. Lui manque-t-il quelque chose? Non. Ce n'est\r
+point perdre la lumière qu'avoir l'amour. Et quel amour! un amour\r
+entièrement fait de vertu. Il n'y a point de cécité où il y a certitude.\r
+L'âme à tâtons cherche l'âme, et la trouve. Et cette âme trouvée et\r
+prouvée est une femme. Une main vous soutient, c'est la sienne; une\r
+bouche effleure votre front, c'est sa bouche; vous entendez une\r
+respiration tout près de vous, c'est elle. Tout avoir d'elle, depuis son\r
+culte jusqu'à sa pitié, n'être jamais quitté, avoir cette douce\r
+faiblesse qui vous secourt, s'appuyer sur ce roseau inébranlable,\r
+toucher de ses mains la providence et pouvoir la prendre dans ses bras,\r
+Dieu palpable, quel ravissement! Le coeur, cette céleste fleur obscure,\r
+entre dans un épanouissement mystérieux. On ne donnerait pas cette ombre\r
+pour toute la clarté. L'âme ange est là, sans cesse là; si elle\r
+s'éloigne, c'est pour revenir; elle s'efface comme le rêve et reparaît\r
+comme la réalité. On sent de la chaleur qui approche, la voilà. On\r
+déborde de sérénité, de gaîté et d'extase; on est un rayonnement dans la\r
+nuit. Et mille petits soins. Des riens qui sont énormes dans ce vide.\r
+Les plus ineffables accents de la voix féminine employés à vous bercer,\r
+et suppléant pour vous à l'univers évanoui. On est caressé avec de\r
+l'âme. On ne voit rien, mais on se sent adoré. C'est un paradis de\r
+ténèbres.\r
+\r
+C'est de ce paradis que monseigneur Bienvenu était passé à l'autre.\r
+\r
+L'annonce de sa mort fut reproduite par le journal local de\r
+Montreuil-sur-mer. M. Madeleine parut le lendemain tout en noir avec un\r
+crêpe à son chapeau.\r
+\r
+On remarqua dans la ville ce deuil, et l'on jasa. Cela parut une lueur\r
+sur l'origine de M. Madeleine. On en conclut qu'il avait quelque\r
+alliance avec le vénérable évêque. _Il drape pour l'évêque de Digne_,\r
+dirent les salons; cela rehaussa fort M. Madeleine, et lui donna\r
+subitement et d'emblée une certaine considération dans le monde noble de\r
+Montreuil-sur-mer. Le microscopique faubourg Saint-Germain de l'endroit\r
+songea à faire cesser la quarantaine de M. Madeleine, parent probable\r
+d'un évêque. M. Madeleine s'aperçut de l'avancement qu'il obtenait à\r
+plus de révérences des vieilles femmes et à plus de sourires des jeunes.\r
+Un soir, une doyenne de ce petit grand monde-là, curieuse par droit\r
+d'ancienneté, se hasarda à lui demander:\r
+\r
+--Monsieur le maire est sans doute cousin du feu évêque de Digne?\r
+\r
+Il dit:\r
+\r
+--Non, madame.\r
+\r
+--Mais, reprit la douairière, vous en portez le deuil?\r
+\r
+Il répondit:\r
+\r
+--C'est que dans ma jeunesse j'ai été laquais dans sa famille.\r
+\r
+Une remarque qu'on faisait encore, c'est que, chaque fois qu'il passait\r
+dans la ville un jeune savoyard courant le pays et cherchant des\r
+cheminées à ramoner, M. le maire le faisait appeler, lui demandait son\r
+nom, et lui donnait de l'argent. Les petits savoyards se le disaient, et\r
+il en passait beaucoup.\r
+\r
+\r
+\r
+\r
+Chapitre V\r
+\r
+Vagues éclairs à l'horizon\r
+\r
+\r
+Peu à peu, et avec le temps, toutes les oppositions étaient tombées. Il\r
+y avait eu d'abord contre M. Madeleine, sorte de loi que subissent\r
+toujours ceux qui s'élèvent, des noirceurs et des calomnies, puis ce ne\r
+fut plus que des méchancetés, puis ce ne fut que des malices, puis cela\r
+s'évanouit tout à fait; le respect devint complet, unanime, cordial, et\r
+il arriva un moment, vers 1821, où ce mot: monsieur le maire, fut\r
+prononcé à Montreuil-sur-mer presque du même accent que ce mot:\r
+monseigneur l'évêque, était prononcé à Digne en 1815. On venait de dix\r
+lieues à la ronde consulter M. Madeleine. Il terminait les différends,\r
+il empêchait les procès, il réconciliait les ennemis. Chacun le prenait\r
+pour juge de son bon droit. Il semblait qu'il eût pour âme le livre de\r
+la loi naturelle. Ce fut comme une contagion de vénération qui, en six\r
+ou sept ans et de proche en proche, gagna tout le pays.\r
+\r
+Un seul homme, dans la ville et dans l'arrondissement, se déroba\r
+absolument à cette contagion, et, quoi que fît le père Madeleine, y\r
+demeura rebelle, comme si une sorte d'instinct, incorruptible et\r
+imperturbable, l'éveillait et l'inquiétait. Il semblerait en effet qu'il\r
+existe dans certains hommes un véritable instinct bestial, pur et\r
+intègre comme tout instinct, qui crée les antipathies et les sympathies,\r
+qui sépare fatalement une nature d'une autre nature, qui n'hésite pas,\r
+qui ne se trouble, ne se tait et ne se dément jamais, clair dans son\r
+obscurité, infaillible, impérieux, réfractaire à tous les conseils de\r
+l'intelligence et à tous les dissolvants de la raison, et qui, de\r
+quelque façon que les destinées soient faites, avertit secrètement\r
+l'homme-chien de la présence de l'homme-chat, et l'homme-renard de la\r
+présence de l'homme-lion.\r
+\r
+Souvent, quand M. Madeleine passait dans une rue, calme, affectueux,\r
+entouré des bénédictions de tous, il arrivait qu'un homme de haute\r
+taille, vêtu d'une redingote gris de fer, armé d'une grosse canne et\r
+coiffé d'un chapeau rabattu, se retournait brusquement derrière lui, et\r
+le suivait des yeux jusqu'à ce qu'il eût disparu, croisant les bras,\r
+secouant lentement la tête, et haussant sa lèvre supérieure avec sa\r
+lèvre inférieure jusqu'à son nez, sorte de grimace significative qui\r
+pourrait se traduire par: «Mais qu'est-ce que c'est que cet\r
+homme-là?--Pour sûr je l'ai vu quelque part.--En tout cas, je ne suis\r
+toujours pas sa dupe.»\r
+\r
+Ce personnage, grave d'une gravité presque menaçante, était de ceux qui,\r
+même rapidement entrevus, préoccupent l'observateur.\r
+\r
+Il se nommait Javert, et il était de la police.\r
+\r
+Il remplissait à Montreuil-sur-mer les fonctions pénibles, mais utiles,\r
+d'inspecteur. Il n'avait pas vu les commencements de Madeleine. Javert\r
+devait le poste qu'il occupait à la protection de M. Chabouillet, le\r
+secrétaire du ministre d'État, comte Anglès, alors préfet de police à\r
+Paris. Quand Javert était arrivé à Montreuil-sur-mer, la fortune du\r
+grand manufacturier était déjà faite, et le père Madeleine était devenu\r
+monsieur Madeleine.\r
+\r
+Certains officiers de police ont une physionomie à part et qui se\r
+complique d'un air de bassesse mêlé à un air d'autorité. Javert avait\r
+cette physionomie, moins la bassesse.\r
+\r
+Dans notre conviction, si les âmes étaient visibles aux yeux, on verrait\r
+distinctement cette chose étrange que chacun des individus de l'espèce\r
+humaine correspond à quelqu'une des espèces de la création animale; et\r
+l'on pourrait reconnaître aisément cette vérité à peine entrevue par le\r
+penseur, que, depuis l'huître jusqu'à l'aigle, depuis le porc jusqu'au\r
+tigre, tous les animaux sont dans l'homme et que chacun d'eux est dans\r
+un homme. Quelquefois même plusieurs d'entre eux à la fois.\r
+\r
+Les animaux ne sont autre chose que les figures de nos vertus et de nos\r
+vices, errantes devant nos yeux, les fantômes visibles de nos âmes. Dieu\r
+nous les montre pour nous faire réfléchir. Seulement, comme les animaux\r
+ne sont que des ombres, Dieu ne les a point faits éducables dans le sens\r
+complet du mot; à quoi bon? Au contraire, nos âmes étant des réalités et\r
+ayant une fin qui leur est propre, Dieu leur a donné l'intelligence,\r
+c'est-à-dire l'éducation possible. L'éducation sociale bien faite peut\r
+toujours tirer d'une âme, quelle qu'elle soit, l'utilité qu'elle\r
+contient.\r
+\r
+Ceci soit dit, bien entendu, au point de vue restreint de la vie\r
+terrestre apparente, et sans préjuger la question profonde de la\r
+personnalité antérieure et ultérieure des êtres qui ne sont pas l'homme.\r
+Le moi visible n'autorise en aucune façon le penseur à nier le moi\r
+latent. Cette réserve faite, passons.\r
+\r
+Maintenant, si l'on admet un moment avec nous que dans tout homme il y a\r
+une des espèces animales de la création, il nous sera facile de dire ce\r
+que c'était que l'officier de paix Javert.\r
+\r
+Les paysans asturiens sont convaincus que dans toute portée de louve il\r
+y a un chien, lequel est tué par la mère, sans quoi en grandissant il\r
+dévorerait les autres petits.\r
+\r
+Donnez une face humaine à ce chien fils d'une louve, et ce sera Javert.\r
+\r
+Javert était né dans une prison d'une tireuse de cartes dont le mari\r
+était aux galères. En grandissant, il pensa qu'il était en dehors de la\r
+société et désespéra d'y rentrer jamais. Il remarqua que la société\r
+maintient irrémissiblement en dehors d'elle deux classes d'hommes, ceux\r
+qui l'attaquent et ceux qui la gardent; il n'avait le choix qu'entre ces\r
+deux classes; en même temps il se sentait je ne sais quel fond de\r
+rigidité, de régularité et de probité, compliqué d'une inexprimable\r
+haine pour cette race de bohèmes dont il était. Il entra dans la police.\r
+\r
+Il y réussit. À quarante ans il était inspecteur.\r
+\r
+Il avait dans sa jeunesse été employé dans les chiourmes du midi.\r
+\r
+Avant d'aller plus loin, entendons-nous sur ce mot face humaine que nous\r
+appliquions tout à l'heure à Javert.\r
+\r
+La face humaine de Javert consistait en un nez camard, avec deux\r
+profondes narines vers lesquelles montaient sur ses deux joues d'énormes\r
+favoris. On se sentait mal à l'aise la première fois qu'on voyait ces\r
+deux forêts et ces deux cavernes. Quand Javert riait, ce qui était rare\r
+et terrible, ses lèvres minces s'écartaient, et laissaient voir, non\r
+seulement ses dents, mais ses gencives, et il se faisait autour de son\r
+nez un plissement épaté et sauvage comme sur un mufle de bête fauve.\r
+Javert sérieux était un dogue; lorsqu'il riait, c'était un tigre. Du\r
+reste, peu de crâne, beaucoup de mâchoire, les cheveux cachant le front\r
+et tombant sur les sourcils, entre les deux yeux un froncement central\r
+permanent comme une étoile de colère, le regard obscur, la bouche pincée\r
+et redoutable, l'air du commandement féroce.\r
+\r
+Cet homme était composé de deux sentiments très simples, et relativement\r
+très bons, mais qu'il faisait presque mauvais à force de les exagérer:\r
+le respect de l'autorité, la haine de la rébellion; et à ses yeux le\r
+vol, le meurtre, tous les crimes, n'étaient que des formes de la\r
+rébellion. Il enveloppait dans une sorte de foi aveugle et profonde tout\r
+ce qui a une fonction dans l'État, depuis le premier ministre jusqu'au\r
+garde champêtre. Il couvrait de mépris, d'aversion et de dégoût tout ce\r
+qui avait franchi une fois le seuil légal du mal. Il était absolu et\r
+n'admettait pas d'exceptions. D'une part il disait:\r
+\r
+--Le fonctionnaire ne peut se tromper; le magistrat n'a jamais tort.\r
+\r
+D'autre part il disait:\r
+\r
+--Ceux-ci sont irrémédiablement perdus. Rien de bon n'en peut sortir.\r
+\r
+Il partageait pleinement l'opinion de ces esprits extrêmes qui\r
+attribuent à la loi humaine je ne sais quel pouvoir de faire ou, si l'on\r
+veut, de constater des damnés, et qui mettent un Styx au bas de la\r
+société. Il était stoïque, sérieux, austère; rêveur triste; humble et\r
+hautain comme les fanatiques. Son regard était une vrille. Cela était\r
+froid et cela perçait. Toute sa vie tenait dans ces deux mots: veiller\r
+et surveiller. Il avait introduit la ligne droite dans ce qu'il y a de\r
+plus tortueux au monde; il avait la conscience de son utilité, la\r
+religion de ses fonctions, et il était espion comme on est prêtre.\r
+Malheur à qui tombait sous sa main! Il eût arrêté son père s'évadant du\r
+bagne et dénoncé sa mère en rupture de ban. Et il l'eût fait avec cette\r
+sorte de satisfaction intérieure que donne la vertu. Avec cela une vie\r
+de privations, l'isolement, l'abnégation, la chasteté, jamais une\r
+distraction. C'était le devoir implacable, la police comprise comme les\r
+Spartiates comprenaient Sparte, un guet impitoyable, une honnêteté\r
+farouche, un mouchard marmoréen, Brutus dans Vidocq.\r
+\r
+Toute la personne de Javert exprimait l'homme qui épie et qui se dérobe.\r
+L'école mystique de Joseph de Maistre, laquelle à cette époque\r
+assaisonnait de haute cosmogonie ce qu'on appelait les journaux ultras,\r
+n'eût pas manqué de dire que Javert était un symbole. On ne voyait pas\r
+son front qui disparaissait sous son chapeau, on ne voyait pas ses yeux\r
+qui se perdaient sous ses sourcils, on ne voyait pas son menton qui\r
+plongeait dans sa cravate, on ne voyait pas ses mains qui rentraient\r
+dans ses manches, on ne voyait pas sa canne qu'il portait sous sa\r
+redingote. Mais l'occasion venue, on voyait tout à coup sortir de toute\r
+cette ombre, comme d'une embuscade, un front anguleux et étroit, un\r
+regard funeste, un menton menaçant, des mains énormes; et un gourdin\r
+monstrueux.\r
+\r
+À ses moments de loisir, qui étaient peu fréquents, tout en haïssant les\r
+livres, il lisait; ce qui fait qu'il n'était pas complètement illettré.\r
+Cela se reconnaissait à quelque emphase dans la parole.\r
+\r
+Il n'avait aucun vice, nous l'avons dit. Quand il était content de lui,\r
+il s'accordait une prise de tabac. Il tenait à l'humanité par là.\r
+\r
+On comprendra sans peine que Javert était l'effroi de toute cette classe\r
+que la statistique annuelle du ministère de la justice désigne sous la\r
+rubrique: _Gens sans aveu_. Le nom de Javert prononcé les mettait en\r
+déroute; la face de Javert apparaissant les pétrifiait.\r
+\r
+Tel était cet homme formidable.\r
+\r
+Javert était comme un oeil toujours fixé sur M. Madeleine. Oeil plein de\r
+soupçon et de conjectures. M. Madeleine avait fini par s'en apercevoir,\r
+mais il sembla que cela fût insignifiant pour lui. Il ne fit pas même\r
+une question à Javert, il ne le cherchait ni ne l'évitait, et il\r
+portait, sans paraître y faire attention, ce regard gênant et presque\r
+pesant. Il traitait Javert comme tout le monde, avec aisance et bonté.\r
+\r
+À quelques paroles échappées à Javert, on devinait qu'il avait recherché\r
+secrètement, avec cette curiosité qui tient à la race et où il entre\r
+autant d'instinct que de volonté, toutes les traces antérieures que le\r
+père Madeleine avait pu laisser ailleurs. Il paraissait savoir, et il\r
+disait parfois à mots couverts, que quelqu'un avait pris certaines\r
+informations dans un certain pays sur une certaine famille disparue. Une\r
+fois il lui arriva de dire, se parlant à lui-même:\r
+\r
+--Je crois que je le tiens!\r
+\r
+Puis il resta trois jours pensif sans prononcer une parole. Il paraît\r
+que le fil qu'il croyait tenir s'était rompu. Du reste, et ceci est le\r
+correctif nécessaire à ce que le sens de certains mots pourrait\r
+présenter de trop absolu, il ne peut y avoir rien de vraiment\r
+infaillible dans une créature humaine, et le propre de l'instinct est\r
+précisément de pouvoir être troublé, dépisté et dérouté. Sans quoi il\r
+serait supérieur à l'intelligence, et la bête se trouverait avoir une\r
+meilleure lumière que l'homme.\r
+\r
+Javert était évidemment quelque peu déconcerté par le complet naturel et\r
+la tranquillité de M. Madeleine.\r
+\r
+Un jour pourtant son étrange manière d'être parut faire impression sur\r
+M. Madeleine. Voici à quelle occasion.\r
+\r
+\r
+\r
+\r
+Chapitre VI\r
+\r
+Le père Fauchelevent\r
+\r
+\r
+M. Madeleine passait un matin dans une ruelle non pavée de\r
+Montreuil-sur-mer. Il entendit du bruit et vit un groupe à quelque\r
+distance. Il y alla. Un vieux homme, nommé le père Fauchelevent, venait\r
+de tomber sous sa charrette dont le cheval s'était abattu.\r
+\r
+Ce Fauchelevent était un des rares ennemis qu'eût encore M. Madeleine à\r
+cette époque. Lorsque Madeleine était arrivé dans le pays, Fauchelevent,\r
+ancien tabellion et paysan presque lettré, avait un commerce qui\r
+commençait à aller mal. Fauchelevent avait vu ce simple ouvrier qui\r
+s'enrichissait, tandis que lui, maître, se ruinait. Cela l'avait rempli\r
+de jalousie, et il avait fait ce qu'il avait pu en toute occasion pour\r
+nuire à Madeleine. Puis la faillite était venue, et, vieux, n'ayant plus\r
+à lui qu'une charrette et un cheval, sans famille et sans enfants du\r
+reste, pour vivre il s'était fait charretier.\r
+\r
+Le cheval avait les deux cuisses cassées et ne pouvait se relever. Le\r
+vieillard était engagé entre les roues. La chute avait été tellement\r
+malheureuse que toute la voiture pesait sur sa poitrine. La charrette\r
+était assez lourdement chargée. Le père Fauchelevent poussait des râles\r
+lamentables. On avait essayé de le tirer, mais en vain. Un effort\r
+désordonné, une aide maladroite, une secousse à faux pouvaient\r
+l'achever. Il était impossible de le dégager autrement qu'en soulevant\r
+la voiture par-dessous. Javert, qui était survenu au moment de\r
+l'accident, avait envoyé chercher un cric.\r
+\r
+M. Madeleine arriva. On s'écarta avec respect.\r
+\r
+--À l'aide! criait le vieux Fauchelevent. Qui est-ce qui est bon enfant\r
+pour sauver le vieux?\r
+\r
+M. Madeleine se tourna vers les assistants:\r
+\r
+--A-t-on un cric?\r
+\r
+--On en est allé quérir un, répondit un paysan.\r
+\r
+--Dans combien de temps l'aura-t-on?\r
+\r
+--On est allé au plus près, au lieu Flachot, où il y a un maréchal; mais\r
+c'est égal, il faudra bien un bon quart d'heure.\r
+\r
+--Un quart d'heure! s'écria Madeleine.\r
+\r
+Il avait plu la veille, le sol était détrempé, la charrette s'enfonçait\r
+dans la terre à chaque instant et comprimait de plus en plus la poitrine\r
+du vieux charretier. Il était évident qu'avant cinq minutes il aurait\r
+les côtes brisées.\r
+\r
+--Il est impossible d'attendre un quart d'heure, dit Madeleine aux\r
+paysans qui regardaient.\r
+\r
+--Il faut bien!\r
+\r
+--Mais il ne sera plus temps! Vous ne voyez donc pas que la charrette\r
+s'enfonce?\r
+\r
+--Dame!\r
+\r
+--Écoutez, reprit Madeleine, il y a encore assez de place sous la\r
+voiture pour qu'un homme s'y glisse et la soulève avec son dos. Rien\r
+qu'une demi-minute, et l'on tirera le pauvre homme. Y a-t-il ici\r
+quelqu'un qui ait des reins et du coeur? Cinq louis d'or à gagner!\r
+\r
+Personne ne bougea dans le groupe.\r
+\r
+--Dix louis, dit Madeleine.\r
+\r
+Les assistants baissaient les yeux. Un d'eux murmura:\r
+\r
+--Il faudrait être diablement fort. Et puis, on risque de se faire\r
+écraser!\r
+\r
+--Allons! recommença Madeleine, vingt louis! Même silence.\r
+\r
+--Ce n'est pas la bonne volonté qui leur manque, dit une voix.\r
+\r
+M. Madeleine se retourna, et reconnut Javert. Il ne l'avait pas aperçu\r
+en arrivant. Javert continua:\r
+\r
+--C'est la force. Il faudrait être un terrible homme pour faire la chose\r
+de lever une voiture comme cela sur son dos.\r
+\r
+Puis, regardant fixement M. Madeleine, il poursuivit en appuyant sur\r
+chacun des mots qu'il prononçait:\r
+\r
+--Monsieur Madeleine, je n'ai jamais connu qu'un seul homme capable de\r
+faire ce que vous demandez là.\r
+\r
+Madeleine tressaillit.\r
+\r
+Javert ajouta avec un air d'indifférence, mais sans quitter des yeux\r
+Madeleine:\r
+\r
+--C'était un forçat.\r
+\r
+--Ah! dit Madeleine.\r
+\r
+--Du bagne de Toulon.\r
+\r
+Madeleine devint pâle.\r
+\r
+Cependant la charrette continuait à s'enfoncer lentement. Le père\r
+Fauchelevent râlait et hurlait:\r
+\r
+--J'étouffe! Ça me brise les côtes! Un cric! quelque chose! Ah!\r
+\r
+Madeleine regarda autour de lui:\r
+\r
+--Il n'y a donc personne qui veuille gagner vingt louis et sauver la vie\r
+à ce pauvre vieux?\r
+\r
+Aucun des assistants ne remua. Javert reprit:\r
+\r
+--Je n'ai jamais connu qu'un homme qui pût remplacer un cric. C'était ce\r
+forçat.\r
+\r
+--Ah! voilà que ça m'écrase! cria le vieillard.\r
+\r
+Madeleine leva la tête, rencontra l'oeil de faucon de Javert toujours\r
+attaché sur lui, regarda les paysans immobiles, et sourit tristement.\r
+Puis, sans dire une parole, il tomba à genoux, et avant même que la\r
+foule eût eu le temps de jeter un cri, il était sous la voiture.\r
+\r
+Il y eut un affreux moment d'attente et de silence.\r
+\r
+On vit Madeleine presque à plat ventre sous ce poids effrayant essayer\r
+deux fois en vain de rapprocher ses coudes de ses genoux. On lui cria:\r
+\r
+--Père Madeleine! retirez-vous de là!\r
+\r
+Le vieux Fauchelevent lui-même lui dit:\r
+\r
+--Monsieur Madeleine! allez-vous-en! C'est qu'il faut que je meure,\r
+voyez-vous! Laissez-moi! Vous allez vous faire écraser aussi!\r
+\r
+Madeleine ne répondit pas.\r
+\r
+Les assistants haletaient. Les roues avaient continué de s'enfoncer, et\r
+il était déjà devenu presque impossible que Madeleine sortît de dessous\r
+la voiture.\r
+\r
+Tout à coup on vit l'énorme masse s'ébranler, la charrette se soulevait\r
+lentement, les roues sortaient à demi de l'ornière. On entendit une voix\r
+étouffée qui criait:\r
+\r
+--Dépêchez-vous! aidez!\r
+\r
+C'était Madeleine qui venait de faire un dernier effort.\r
+\r
+Ils se précipitèrent. Le dévouement d'un seul avait donné de la force et\r
+du courage à tous. La charrette fut enlevée par vingt bras. Le vieux\r
+Fauchelevent était sauvé.\r
+\r
+Madeleine se releva. Il était blême, quoique ruisselant de sueur. Ses\r
+habits étaient déchirés et couverts de boue. Tous pleuraient. Le\r
+vieillard lui baisait les genoux et l'appelait le bon Dieu. Lui, il\r
+avait sur le visage je ne sais quelle expression de souffrance heureuse\r
+et céleste, et il fixait son oeil tranquille sur Javert qui le regardait\r
+toujours.\r
+\r
+\r
+\r
+\r
+Chapitre VII\r
+\r
+Fauchelevent devient jardinier à Paris\r
+\r
+\r
+Fauchelevent s'était démis la rotule dans sa chute. Le père Madeleine le\r
+fit transporter dans une infirmerie qu'il avait établie pour ses\r
+ouvriers dans le bâtiment même de sa fabrique et qui était desservie par\r
+deux soeurs de charité. Le lendemain matin, le vieillard trouva un\r
+billet de mille francs sur sa table de nuit, avec ce mot de la main du\r
+père Madeleine: _Je vous achète votre charrette et votre cheval_. La\r
+charrette était brisée et le cheval était mort. Fauchelevent guérit,\r
+mais son genou resta ankylosé. M. Madeleine, par les recommandations des\r
+soeurs et de son curé, fit placer le bonhomme comme jardinier dans un\r
+couvent de femmes du quartier Saint-Antoine à Paris.\r
+\r
+Quelque temps après, M. Madeleine fut nommé maire. La première fois que\r
+Javert vit M. Madeleine revêtu de l'écharpe qui lui donnait toute\r
+autorité sur la ville, il éprouva cette sorte de frémissement\r
+qu'éprouverait un dogue qui flairerait un loup sous les habits de son\r
+maître. À partir de ce moment, il l'évita le plus qu'il put. Quand les\r
+besoins du service l'exigeaient impérieusement et qu'il ne pouvait faire\r
+autrement que de se trouver avec M. le maire, il lui parlait avec un\r
+respect profond.\r
+\r
+Cette prospérité créée à Montreuil-sur-mer par le père Madeleine avait,\r
+outre les signes visibles que nous avons indiqués, un autre symptôme\r
+qui, pour n'être pas visible, n'était pas moins significatif. Ceci ne\r
+trompe jamais.\r
+\r
+Quand la population souffre, quand le travail manque, quand le commerce\r
+est nul, le contribuable résiste à l'impôt par pénurie, épuise et\r
+dépasse les délais, et l'état dépense beaucoup d'argent en frais de\r
+contrainte et de rentrée. Quand le travail abonde, quand le pays est\r
+heureux et riche, l'impôt se paye aisément et coûte peu à l'état. On\r
+peut dire que la misère et la richesse publiques ont un thermomètre\r
+infaillible, les frais de perception de l'impôt. En sept ans, les frais\r
+de perception de l'impôt s'étaient réduits des trois quarts dans\r
+l'arrondissement de Montreuil-sur-mer, ce qui faisait fréquemment citer\r
+cet arrondissement entre tous par M. de Villèle, alors ministre des\r
+finances.\r
+\r
+Telle était la situation du pays, lorsque Fantine y revint. Personne ne\r
+se souvenait plus d'elle. Heureusement la porte de la fabrique de M.\r
+Madeleine était comme un visage ami. Elle s'y présenta, et fut admise\r
+dans l'atelier des femmes. Le métier était tout nouveau pour Fantine,\r
+elle n'y pouvait être bien adroite, elle ne tirait donc de sa journée de\r
+travail que peu de chose, mais enfin cela suffisait, le problème était\r
+résolu, elle gagnait sa vie.\r
+\r
+\r
+\r
+\r
+Chapitre VIII\r
+\r
+Madame Victurnien dépense trente-cinq francs pour la morale\r
+\r
+\r
+Quand Fantine vit qu'elle vivait, elle eut un moment de joie. Vivre\r
+honnêtement de son travail, quelle grâce du ciel! Le goût du travail lui\r
+revint vraiment. Elle acheta un miroir, se réjouit d'y regarder sa\r
+jeunesse, ses beaux cheveux et ses belles dents, oublia beaucoup de\r
+choses, ne songea plus qu'à sa Cosette et à l'avenir possible, et fut\r
+presque heureuse. Elle loua une petite chambre et la meubla à crédit sur\r
+son travail futur; reste de ses habitudes de désordre.\r
+\r
+Ne pouvant pas dire qu'elle était mariée, elle s'était bien gardée,\r
+comme nous l'avons déjà fait entrevoir, de parler de sa petite fille.\r
+\r
+En ces commencements, on l'a vu, elle payait exactement les Thénardier.\r
+Comme elle ne savait que signer, elle était obligée de leur écrire par\r
+un écrivain public.\r
+\r
+Elle écrivait souvent. Cela fut remarqué. On commença à dire tout bas\r
+dans l'atelier des femmes que Fantine «écrivait des lettres» et qu'«elle\r
+avait des allures».\r
+\r
+Il n'y a rien de tel pour épier les actions des gens que ceux qu'elles\r
+ne regardent pas.--Pourquoi ce monsieur ne vient-il jamais qu'à la\r
+brune? pourquoi monsieur un tel n'accroche-t-il jamais sa clef au clou\r
+le jeudi? pourquoi prend-il toujours les petites rues? pourquoi madame\r
+descend-elle toujours de son fiacre avant d'arriver à la maison?\r
+pourquoi envoie-t-elle acheter un cahier de papier à lettres, quand elle\r
+en a «plein sa papeterie?» etc., etc.--Il existe des êtres qui, pour\r
+connaître le mot de ces énigmes, lesquelles leur sont du reste\r
+parfaitement indifférentes, dépensent plus d'argent, prodiguent plus de\r
+temps, se donnent plus de peine qu'il n'en faudrait pour dix bonnes\r
+actions; et cela, gratuitement, pour le plaisir, sans être payés de la\r
+curiosité autrement que par la curiosité. Ils suivront celui-ci ou\r
+celle-là des jours entiers, feront faction des heures à des coins de\r
+rue, sous des portes d'allées, la nuit, par le froid et par la pluie,\r
+corrompront des commissionnaires, griseront des cochers de fiacre et des\r
+laquais, achèteront une femme de chambre, feront acquisition d'un\r
+portier. Pourquoi? pour rien. Pur acharnement de voir, de savoir et de\r
+pénétrer. Pure démangeaison de dire. Et souvent ces secrets connus, ces\r
+mystères publiés, ces énigmes éclairées du grand jour, entraînent des\r
+catastrophes, des duels, des faillites, des familles ruinées, des\r
+existences brisées, à la grande joie de ceux qui ont «tout découvert»\r
+sans intérêt et par pur instinct. Chose triste.\r
+\r
+Certaines personnes sont méchantes uniquement par besoin de parler. Leur\r
+conversation, causerie dans le salon, bavardage dans l'antichambre, est\r
+comme ces cheminées qui usent vite le bois; il leur faut beaucoup de\r
+combustible; et le combustible, c'est le prochain.\r
+\r
+On observa donc Fantine.\r
+\r
+Avec cela, plus d'une était jalouse de ses cheveux blonds et de ses\r
+dents blanches. On constata que dans l'atelier, au milieu des autres,\r
+elle se détournait souvent pour essuyer une larme. C'étaient les moments\r
+où elle songeait à son enfant; peut-être aussi à l'homme qu'elle avait\r
+aimé.\r
+\r
+C'est un douloureux labeur que la rupture des sombres attaches du passé.\r
+\r
+On constata qu'elle écrivait, au moins deux fois par mois, toujours à la\r
+même adresse, et qu'elle affranchissait la lettre. On parvint à se\r
+procurer l'adresse: _Monsieur, Monsieur Thénardier, aubergiste, à\r
+Montfermeil_. On fit jaser au cabaret l'écrivain public, vieux bonhomme\r
+qui ne pouvait pas emplir son estomac de vin rouge sans vider sa poche\r
+aux secrets. Bref, on sut que Fantine avait un enfant. «Ce devait être\r
+une espèce de fille.» Il se trouva une commère qui fit le voyage de\r
+Montfermeil, parla aux Thénardier, et dit à son retour: «Pour mes\r
+trente-cinq francs, j'en ai eu le coeur net. J'ai vu l'enfant!»\r
+\r
+La commère qui fit cela était une gorgone appelée madame Victurnien,\r
+gardienne et portière de la vertu de tout le monde. Madame Victurnien\r
+avait cinquante-six ans, et doublait le masque de la laideur du masque\r
+de la vieillesse. Voix chevrotante, esprit capricant. Cette vieille\r
+femme avait été jeune, chose étonnante. Dans sa jeunesse, en plein 93,\r
+elle avait épousé un moine échappé du cloître en bonnet rouge et passé\r
+des bernardins aux jacobins. Elle était sèche, rêche, revêche, pointue,\r
+épineuse, presque venimeuse; tout en se souvenant de son moine dont elle\r
+était veuve, et qui l'avait fort domptée et pliée. C'était une ortie où\r
+l'on voyait le froissement du froc. À la restauration, elle s'était\r
+faite bigote, et si énergiquement que les prêtres lui avaient pardonné\r
+son moine. Elle avait un petit bien qu'elle léguait bruyamment à une\r
+communauté religieuse. Elle était fort bien vue à l'évêché d'Arras.\r
+Cette madame Victurnien donc alla à Montfermeil, et revint en disant:\r
+«J'ai vu l'enfant».\r
+\r
+Tout cela prit du temps. Fantine était depuis plus d'un an à la\r
+fabrique, lorsqu'un matin la surveillante de l'atelier lui remit, de la\r
+part de M. le maire, cinquante francs, en lui disant qu'elle ne faisait\r
+plus partie de l'atelier et en l'engageant, de la part de M. le maire, à\r
+quitter le pays.\r
+\r
+C'était précisément dans ce même mois que les Thénardier, après avoir\r
+demandé douze francs au lieu de six, venaient d'exiger quinze francs au\r
+lieu de douze.\r
+\r
+Fantine fut atterrée. Elle ne pouvait s'en aller du pays, elle devait\r
+son loyer et ses meubles. Cinquante francs ne suffisaient pas pour\r
+acquitter cette dette. Elle balbutia quelques mots suppliants. La\r
+surveillante lui signifia qu'elle eût à sortir sur-le-champ de\r
+l'atelier. Fantine n'était du reste qu'une ouvrière médiocre. Accablée\r
+de honte plus encore que de désespoir, elle quitta l'atelier et rentra\r
+dans sa chambre. Sa faute était donc maintenant connue de tous!\r
+\r
+Elle ne se sentit plus la force de dire un mot. On lui conseilla de voir\r
+M. le maire; elle n'osa pas. M. le maire lui donnait cinquante francs,\r
+parce qu'il était bon, et la chassait, parce qu'il était juste. Elle\r
+plia sous cet arrêt.\r

+\r
+Succès de Madame Victurnien\r
+\r
+\r
+La veuve du moine fut donc bonne à quelque chose.\r
+\r
+Du reste, M. Madeleine n'avait rien su de tout cela. Ce sont là de ces\r
+combinaisons d'événements dont la vie est pleine. M. Madeleine avait\r
+pour habitude de n'entrer presque jamais dans l'atelier des femmes. Il\r
+avait mis à la tête de cet atelier une vieille fille, que le curé lui\r
+avait donnée, et il avait toute confiance dans cette surveillante,\r
+personne vraiment respectable, ferme, équitable, intègre, remplie de la\r
+charité qui consiste à donner, mais n'ayant pas au même degré la charité\r
+qui consiste à comprendre et à pardonner. M. Madeleine se remettait de\r
+tout sur elle. Les meilleurs hommes sont souvent forcés de déléguer leur\r
+autorité. C'est dans cette pleine puissance et avec la conviction\r
+qu'elle faisait bien, que la surveillante avait instruit le procès,\r
+jugé, condamné et exécuté Fantine.\r
+\r
+Quant aux cinquante francs, elle les avait donnés sur une somme que M.\r
+Madeleine lui confiait pour aumônes et secours aux ouvrières et dont\r
+elle ne rendait pas compte.\r
+\r
+Fantine s'offrit comme servante dans le pays; elle alla d'une maison à\r
+l'autre. Personne ne voulut d'elle. Elle n'avait pu quitter la ville. Le\r
+marchand fripier auquel elle devait ses meubles, quels meubles! lui\r
+avait dit: «Si vous vous en allez, je vous fais arrêter comme voleuse.»\r
+Le propriétaire auquel elle devait son loyer, lui avait dit:\r
+\r
+«Vous êtes jeune et jolie, vous pouvez payer.» Elle partagea les\r
+cinquante francs entre le propriétaire et le fripier, rendit au marchand\r
+les trois quarts de son mobilier, ne garda que le nécessaire, et se\r
+trouva sans travail, sans état, n'ayant plus que son lit, et devant\r
+encore environ cent francs.\r
+\r
+Elle se mit à coudre de grosses chemises pour les soldats de la\r
+garnison, et gagnait douze sous par jour. Sa fille lui en coûtait dix.\r
+C'est en ce moment qu'elle commença à mal payer les Thénardier.\r
+\r
+Cependant une vieille femme qui lui allumait sa chandelle quand elle\r
+rentrait le soir, lui enseigna l'art de vivre dans la misère. Derrière\r
+vivre de peu, il y a vivre de rien. Ce sont deux chambres; la première\r
+est obscure, la seconde est noire.\r
+\r
+Fantine apprit comment on se passe tout à fait de feu en hiver, comment\r
+on renonce à un oiseau qui vous mange un liard de millet tous les deux\r
+jours, comment on fait de son jupon sa couverture et de sa couverture\r
+son jupon, comment on ménage sa chandelle en prenant son repas à la\r
+lumière de la fenêtre d'en face. On ne sait pas tout ce que certains\r
+êtres faibles, qui ont vieilli dans le dénûment et l'honnêteté, savent\r
+tirer d'un sou. Cela finit par être un talent. Fantine acquit ce sublime\r
+talent et reprit un peu de courage.\r
+\r
+À cette époque, elle disait à une voisine:\r
+\r
+--Bah! je me dis: en ne dormant que cinq heures et en travaillant tout\r
+le reste à mes coutures, je parviendrai bien toujours à gagner à peu\r
+près du pain. Et puis, quand on est triste, on mange moins. Eh bien! des\r
+souffrances, des inquiétudes, un peu de pain d'un côté, des chagrins de\r
+l'autre, tout cela me nourrira.\r
+\r
+Dans cette détresse, avoir sa petite fille eût été un étrange bonheur.\r
+Elle songea à la faire venir. Mais quoi! lui faire partager son\r
+dénûment! Et puis, elle devait aux Thénardier! comment s'acquitter? Et\r
+le voyage! comment le payer?\r
+\r
+La vieille qui lui avait donné ce qu'on pourrait appeler des leçons de\r
+vie indigente était une sainte fille nommée Marguerite, dévote de la\r
+bonne dévotion, pauvre, et charitable pour les pauvres et même pour les\r
+riches, sachant tout juste assez écrire pour signer _Margueritte_, et\r
+croyant en Dieu, ce qui est la science.\r
+\r
+Il y a beaucoup de ces vertus-là en bas; un jour elles seront en haut.\r
+Cette vie a un lendemain.\r
+\r
+Dans les premiers temps, Fantine avait été si honteuse qu'elle n'avait\r
+pas osé sortir. Quand elle était dans la rue, elle devinait qu'on se\r
+retournait derrière elle et qu'on la montrait du doigt; tout le monde la\r
+regardait et personne ne la saluait; le mépris âcre et froid des\r
+passants lui pénétrait dans la chair et dans l'âme comme une bise.\r
+\r
+Dans les petites villes, il semble qu'une malheureuse soit nue sous les\r
+sarcasmes et la curiosité de tous. À Paris, du moins, personne ne vous\r
+connaît, et cette obscurité est un vêtement. Oh! comme elle eût souhaité\r
+venir à Paris! Impossible.\r
+\r
+Il fallut bien s'accoutumer à la déconsidération, comme elle s'était\r
+accoutumée à l'indigence. Peu à peu elle en prit son parti. Après deux\r
+ou trois mois elle secoua la honte et se remit à sortir comme si de rien\r
+n'était.\r
+\r
+--Cela m'est bien égal, dit-elle.\r
+\r
+Elle alla et vint, la tête haute, avec un sourire amer, et sentit\r
+qu'elle devenait effrontée.\r
+\r
+Madame Victurnien quelquefois la voyait passer de sa fenêtre, remarquait\r
+la détresse de «cette créature», grâce à elle "remise à sa place", et se\r
+félicitait. Les méchants ont un bonheur noir.\r
+\r
+L'excès du travail fatiguait Fantine, et la petite toux sèche qu'elle\r
+avait augmenta. Elle disait quelquefois à sa voisine Marguerite: «Tâtez\r
+donc comme mes mains sont chaudes.»\r
+\r
+Cependant le matin, quand elle peignait avec un vieux peigne cassé ses\r
+beaux cheveux qui ruisselaient comme de la soie floche, elle avait une\r
+minute de coquetterie heureuse.\r
+\r
+\r
+\r
+\r
+Chapitre X\r
+\r
+Suite du succès\r
+\r
+\r
+Elle avait été congédiée vers la fin de l'hiver; l'été se passa, mais\r
+l'hiver revint. Jours courts, moins de travail. L'hiver, point de\r
+chaleur, point de lumière, point de midi, le soir touche au matin,\r
+brouillard, crépuscule, la fenêtre est grise, on n'y voit pas clair. Le\r
+ciel est un soupirail. Toute la journée est une cave. Le soleil a l'air\r
+d'un pauvre. L'affreuse saison! L'hiver change en pierre l'eau du ciel\r
+et le coeur de l'homme. Ses créanciers la harcelaient.\r
+\r
+Fantine gagnait trop peu. Ses dettes avaient grossi. Les Thénardier, mal\r
+payés, lui écrivaient à chaque instant des lettres dont le contenu la\r
+désolait et dont le port la ruinait. Un jour ils lui écrivirent que sa\r
+petite Cosette était toute nue par le froid qu'il faisait, qu'elle avait\r
+besoin d'une jupe de laine, et qu'il fallait au moins que la mère\r
+envoyât dix francs pour cela. Elle reçut la lettre, et la froissa dans\r
+ses mains tout le jour. Le soir elle entra chez un barbier qui habitait\r
+le coin de la rue, et défit son peigne. Ses admirables cheveux blonds\r
+lui tombèrent jusqu'aux reins.\r
+\r
+--Les beaux cheveux! s'écria le barbier.\r
+\r
+--Combien m'en donneriez-vous? dit-elle.\r
+\r
+--Dix francs.\r
+\r
+--Coupez-les.\r
+\r
+Elle acheta une jupe de tricot et l'envoya aux Thénardier.\r
+\r
+Cette jupe fit les Thénardier furieux. C'était de l'argent qu'ils\r
+voulaient. Ils donnèrent la jupe à Eponine. La pauvre Alouette continua\r
+de frissonner.\r
+\r
+Fantine pensa: «Mon enfant n'a plus froid. Je l'ai habillée de mes\r
+cheveux.» Elle mettait de petits bonnets ronds qui cachaient sa tête\r
+tondue et avec lesquels elle était encore jolie.\r
+\r
+Un travail ténébreux se faisait dans le coeur de Fantine. Quand elle vit\r
+qu'elle ne pouvait plus se coiffer, elle commença à tout prendre en\r
+haine autour d'elle. Elle avait longtemps partagé la vénération de tous\r
+pour le père Madeleine; cependant, à force de se répéter que c'était lui\r
+qui l'avait chassée, et qu'il était la cause de son malheur, elle en\r
+vint à le haïr lui aussi, lui surtout. Quand elle passait devant la\r
+fabrique aux heures où les ouvriers sont sur la porte, elle affectait de\r
+rire et de chanter.\r
+\r
+Une vieille ouvrière qui la vit une fois chanter et rire de cette façon\r
+dit:\r
+\r
+--Voilà une fille qui finira mal.\r
+\r
+Elle prit un amant, le premier venu, un homme qu'elle n'aimait pas, par\r
+bravade, avec la rage dans le coeur. C'était un misérable, une espèce de\r
+musicien mendiant, un oisif gueux, qui la battait, et qui la quitta\r
+comme elle l'avait pris, avec dégoût. Elle adorait son enfant.\r
+\r
+Plus elle descendait, plus tout devenait sombre autour d'elle plus ce\r
+doux petit ange rayonnait dans le fond de son âme. Elle disait. Quand je\r
+serai riche, j'aurai ma Cosette avec moi; et elle riait. La toux ne la\r
+quittait pas, et elle avait des sueurs dans le dos.\r
+\r
+Un jour elle reçut des Thénardier une lettre ainsi conçue:\r
+\r
+«Cosette est malade d'une maladie qui est dans le pays. Une fièvre\r
+miliaire, qu'ils appellent. Il faut des drogues chères. Cela nous ruine\r
+et nous ne pouvons plus payer. Si vous ne nous envoyez pas quarante\r
+francs avant huit jours, la petite est morte.»\r
+\r
+Elle se mit à rire aux éclats, et elle dit à sa vieille voisine:\r
+\r
+--Ah! ils sont bons! quarante francs! que ça! ça fait deux napoléons! Où\r
+veulent-ils que je les prenne? Sont-ils bêtes, ces paysans!\r
+\r
+Cependant elle alla dans l'escalier près d'une lucarne et relut la\r
+lettre.\r
+\r
+Puis elle descendit l'escalier et sortit en courant et en sautant, riant\r
+toujours. Quelqu'un qui la rencontra lui dit:\r
+\r
+--Qu'est-ce que vous avez donc à être si gaie?\r
+\r
+Elle répondit:\r
+\r
+--C'est une bonne bêtise que viennent de m'écrire des gens de la\r
+campagne. Ils me demandent quarante francs. Paysans, va!\r
+\r
+Comme elle passait sur la place, elle vit beaucoup de monde qui\r
+entourait une voiture de forme bizarre sur l'impériale de laquelle\r
+pérorait tout debout un homme vêtu de rouge. C'était un bateleur\r
+dentiste en tournée, qui offrait au public des râteliers complets, des\r
+opiats, des poudres et des élixirs.\r
+\r
+Fantine se mêla au groupe et se mit à rire comme les autres de cette\r
+harangue où il y avait de l'argot pour la canaille et du jargon pour les\r
+gens comme il faut. L'arracheur de dents vit cette belle fille qui\r
+riait, et s'écria tout à coup:\r
+\r
+--Vous avez de jolies dents, la fille qui riez là. Si vous voulez me\r
+vendre vos deux palettes, je vous donne de chaque un napoléon d'or.\r
+\r
+--Qu'est-ce que c'est que ça, mes palettes? demanda Fantine.\r
+\r
+--Les palettes, reprit le professeur dentiste, c'est les dents de\r
+devant, les deux d'en haut.\r
+\r
+--Quelle horreur! s'écria Fantine.\r
+\r
+--Deux napoléons! grommela une vieille édentée qui était là. Qu'en voilà\r
+une qui est heureuse!\r
+\r
+Fantine s'enfuit, et se boucha les oreilles pour ne pas entendre la voix\r
+enrouée de l'homme qui lui criait: Réfléchissez, la belle! deux\r
+napoléons, ça peut servir. Si le coeur vous en dit, venez ce soir à\r
+l'auberge du _Tillac d'argent_, vous m'y trouverez.\r
+\r
+Fantine rentra, elle était furieuse et conta la chose à sa bonne voisine\r
+Marguerite:\r
+\r
+--Comprenez-vous cela? ne voilà-t-il pas un abominable homme? comment\r
+laisse-t-on des gens comme cela aller dans le pays! M'arracher mes deux\r
+dents de devant! mais je serais horrible! Les cheveux repoussent, mais\r
+les dents! Ah! le monstre d'homme! j'aimerais mieux me jeter d'un\r
+cinquième la tête la première sur le pavé! Il m'a dit qu'il serait ce\r
+soir au _Tillac d'argent_.\r
+\r
+--Et qu'est-ce qu'il offrait? demanda Marguerite.\r
+\r
+--Deux napoléons.\r
+\r
+--Cela fait quarante francs.\r
+\r
+--Oui, dit Fantine, cela fait quarante francs.\r
+\r
+Elle resta pensive, et se mit à son ouvrage. Au bout d'un quart d'heure,\r
+elle quitta sa couture et alla relire la lettre des Thénardier sur\r
+l'escalier.\r
+\r
+En rentrant, elle dit à Marguerite qui travaillait près d'elle:\r
+\r
+--Qu'est-ce que c'est donc que cela, une fièvre miliaire? Savez-vous?\r
+\r
+--Oui, répondit la vieille fille, c'est une maladie.\r
+\r
+--Ça a donc besoin de beaucoup de drogues?\r
+\r
+--Oh! des drogues terribles.\r
+\r
+--Où ça vous prend-il?\r
+\r
+--C'est une maladie qu'on a comme ça.\r
+\r
+--Cela attaque donc les enfants?\r
+\r
+--Surtout les enfants.\r
+\r
+--Est-ce qu'on en meurt?\r
+\r
+--Très bien, dit Marguerite.\r
+\r
+Fantine sortit et alla encore une fois relire la lettre sur l'escalier.\r
+\r
+Le soir elle descendit, et on la vit qui se dirigeait du côté de la rue\r
+de Paris où sont les auberges.\r
+\r
+Le lendemain matin, comme Marguerite entrait dans la chambre de Fantine\r
+avant le jour, car elles travaillaient toujours ensemble et de cette\r
+façon n'allumaient qu'une chandelle pour deux, elle trouva Fantine\r
+assise sur son lit, pâle, glacée. Elle ne s'était pas couchée. Son\r
+bonnet était tombé sur ses genoux. La chandelle avait brûlé toute la\r
+nuit et était presque entièrement consumée.\r
+\r
+Marguerite s'arrêta sur le seuil, pétrifiée de cet énorme désordre, et\r
+s'écria:\r
+\r
+--Seigneur! la chandelle qui est toute brûlée! il s'est passé des\r
+événements!\r
+\r
+Puis elle regarda Fantine qui tournait vers elle sa tête sans cheveux.\r
+\r
+Fantine depuis la veille avait vieilli de dix ans.\r
+\r
+--Jésus! fit Marguerite, qu'est-ce que vous avez, Fantine?\r
+\r
+--Je n'ai rien, répondit Fantine. Au contraire. Mon enfant ne mourra pas\r
+de cette affreuse maladie, faute de secours. Je suis contente.\r
+\r
+En parlant ainsi, elle montrait à la vieille fille deux napoléons qui\r
+brillaient sur la table.\r
+\r
+--Ah, Jésus Dieu! dit Marguerite. Mais c'est une fortune! Où avez-vous\r
+eu ces louis d'or?\r
+\r
+--Je les ai eus, répondit Fantine.\r
+\r
+En même temps elle sourit. La chandelle éclairait son visage. C'était un\r
+sourire sanglant. Une salive rougeâtre lui souillait le coin des lèvres,\r
+et elle avait un trou noir dans la bouche.\r
+\r
+Les deux dents étaient arrachées.\r
+\r
+Elle envoya les quarante francs à Montfermeil.\r
+\r
+Du reste c'était une ruse des Thénardier pour avoir de l'argent. Cosette\r
+n'était pas malade.\r
+\r
+Fantine jeta son miroir par la fenêtre. Depuis longtemps elle avait\r
+quitté sa cellule du second pour une mansarde fermée d'un loquet sous le\r
+toit; un de ces galetas dont le plafond fait angle avec le plancher et\r
+vous heurte à chaque instant la tête. Le pauvre ne peut aller au fond de\r
+sa chambre comme au fond de sa destinée qu'en se courbant de plus en\r
+plus. Elle n'avait plus de lit, il lui restait une loque qu'elle\r
+appelait sa couverture, un matelas à terre et une chaise dépaillée. Un\r
+petit rosier qu'elle avait s'était désséché dans un coin, oublié. Dans\r
+l'autre coin, il y avait un pot à beurre à mettre l'eau, qui gelait\r
+l'hiver, et où les différents niveaux de l'eau restaient longtemps\r
+marqués par des cercles de glace. Elle avait perdu la honte, elle perdit\r
+la coquetterie. Dernier signe. Elle sortait avec des bonnets sales. Soit\r
+faute de temps, soit indifférence, elle ne raccommodait plus son linge.\r
+À mesure que les talons s'usaient, elle tirait ses bas dans ses\r
+souliers. Cela se voyait à de certains plis perpendiculaires. Elle\r
+rapiéçait son corset, vieux et usé, avec des morceaux de calicot qui se\r
+déchiraient au moindre mouvement. Les gens auxquels elle devait, lui\r
+faisaient «des scènes», et ne lui laissaient aucun repos. Elle les\r
+trouvait dans la rue, elle les retrouvait dans son escalier. Elle\r
+passait des nuits à pleurer et à songer. Elle avait les yeux très\r
+brillants, et elle sentait une douleur fixe dans l'épaule, vers le haut\r
+de l'omoplate gauche. Elle toussait beaucoup. Elle haïssait profondément\r
+le père Madeleine, et ne se plaignait pas. Elle cousait dix-sept heures\r
+par jour; mais un entrepreneur du travail des prisons, qui faisait\r
+travailler les prisonnières au rabais, fit tout à coup baisser les prix,\r
+ce qui réduisit la journée des ouvrières libres à neuf sous. Dix-sept\r
+heures de travail, et neuf sous par jour! Ses créanciers étaient plus\r
+impitoyables que jamais. Le fripier, qui avait repris presque tous les\r
+meubles, lui disait sans cesse: Quand me payeras-tu, coquine? Que\r
+voulait-on d'elle, bon Dieu! Elle se sentait traquée et il se\r
+développait en elle quelque chose de la bête farouche. Vers le même\r
+temps, le Thénardier lui écrivit que décidément il avait attendu avec\r
+beaucoup trop de bonté, et qu'il lui fallait cent francs, tout de suite;\r
+sinon qu'il mettrait à la porte la petite Cosette, toute convalescente\r
+de sa grande maladie, par le froid, par les chemins, et qu'elle\r
+deviendrait ce qu'elle pourrait, et qu'elle crèverait, si elle voulait.\r
+«Cent francs, songea Fantine! Mais où y a-t-il un état à gagner cent\r
+sous par jour?»\r
+\r
+--Allons! dit-elle, vendons le reste.\r
+\r
+L'infortunée se fit fille publique.\r
+\r
+\r
+\r
+\r
+Chapitre XI\r
+\r
+_Christus nos liberavit_\r
+\r
+\r
+Qu'est-ce que c'est que cette histoire de Fantine? C'est la société\r
+achetant une esclave.\r
+\r
+À qui? À la misère.\r
+\r
+À la faim, au froid, à l'isolement, à l'abandon, au dénûment. Marché\r
+douloureux. Une âme pour un morceau de pain. La misère offre, la société\r
+accepte.\r
+\r
+La sainte loi de Jésus-Christ gouverne notre civilisation, mais elle ne\r
+la pénètre pas encore. On dit que l'esclavage a disparu de la\r
+civilisation européenne. C'est une erreur. Il existe toujours, mais il\r
+ne pèse plus que sur la femme, et il s'appelle prostitution.\r
+\r
+Il pèse sur la femme, c'est-à-dire sur la grâce, sur la faiblesse, sur\r
+la beauté, sur la maternité. Ceci n'est pas une des moindres hontes de\r
+l'homme.\r
+\r
+Au point de ce douloureux drame où nous sommes arrivés, il ne reste plus\r
+rien à Fantine de ce qu'elle a été autrefois. Elle est devenue marbre en\r
+devenant boue. Qui la touche a froid. Elle passe, elle vous subit et\r
+elle vous ignore; elle est la figure déshonorée et sévère. La vie et\r
+l'ordre social lui ont dit leur dernier mot. Il lui est arrivé tout ce\r
+qui lui arrivera. Elle a tout ressenti, tout supporté, tout éprouvé,\r
+tout souffert, tout perdu, tout pleuré. Elle est résignée de cette\r
+résignation qui ressemble à l'indifférence comme la mort ressemble au\r
+sommeil. Elle n'évite plus rien. Elle ne craint plus rien. Tombe sur\r
+elle toute la nuée et passe sur elle tout l'océan! que lui importe!\r
+c'est une éponge imbibée.\r
+\r
+Elle le croit du moins, mais c'est une erreur de s'imaginer qu'on épuise\r
+le sort et qu'on touche le fond de quoi que ce soit.\r
+\r
+Hélas! qu'est-ce que toutes ces destinées ainsi poussées pêle-mêle? où\r
+vont-elles? pourquoi sont-elles ainsi?\r
+\r
+Celui qui sait cela voit toute l'ombre.\r
+\r
+Il est seul. Il s'appelle Dieu.\r
+\r

+\r
+Chapitre XII\r
+\r
+Le désoeuvrement de M. Bamatabois\r
+\r
+\r
+Il y a dans toutes les petites villes, et il y avait à Montreuil-sur-mer\r
+en particulier, une classe de jeunes gens qui grignotent quinze cents\r
+livres de rente en province du même air dont leurs pareils dévorent à\r
+Paris deux cent mille francs par an. Ce sont des êtres de la grande\r
+espèce neutre; hongres, parasites, nuls, qui ont un peu de terre, un peu\r
+de sottise et un peu d'esprit, qui seraient des rustres dans un salon et\r
+se croient des gentilshommes au cabaret, qui disent: mes prés, mes bois,\r
+mes paysans, sifflent les actrices du théâtre pour prouver qu'ils sont\r
+gens de goût, querellent les officiers de la garnison pour montrer\r
+qu'ils sont gens de guerre, chassent, fument, bâillent, boivent, sentent\r
+le tabac, jouent au billard, regardent les voyageurs descendre de\r
+diligence, vivent au café, dînent à l'auberge, ont un chien qui mange\r
+les os sous la table et une maîtresse qui pose les plats dessus,\r
+tiennent à un sou, exagèrent les modes, admirent la tragédie, méprisent\r
+les femmes, usent leurs vieilles bottes, copient Londres à travers Paris\r
+et Paris à travers Pont-à-Mousson, vieillissent hébétés, ne travaillent\r
+pas, ne servent à rien et ne nuisent pas à grand'chose.\r
+\r
+M. Félix Tholomyès, resté dans sa province et n'ayant jamais vu Paris,\r
+serait un de ces hommes-là.\r
+\r
+S'ils étaient plus riches, on dirait: ce sont des élégants; s'ils\r
+étaient plus pauvres, on dirait: ce sont des fainéants. Ce sont tout\r
+simplement des désoeuvrés. Parmi ces désoeuvrés, il y a des ennuyeux,\r
+des ennuyés, des rêvasseurs, et quelques drôles.\r
+\r
+Dans ce temps-là, un élégant se composait d'un grand col, d'une grande\r
+cravate, d'une montre à breloques, de trois gilets superposés de\r
+couleurs différentes, le bleu et le rouge en dedans, d'un habit couleur\r
+olive à taille courte, à queue de morue, à double rangée de boutons\r
+d'argent serrés les uns contre les autres et montant jusque sur\r
+l'épaule, et d'un pantalon olive plus clair, orné sur les deux coutures\r
+d'un nombre de côtes indéterminé, mais toujours impair, variant de une à\r
+onze, limite qui n'était jamais franchie. Ajoutez à cela des\r
+souliers-bottes avec de petits fers au talon, un chapeau à haute forme\r
+et à bords étroits, des cheveux en touffe, une énorme canne, et une\r
+conversation rehaussée des calembours de Potier. Sur le tout des éperons\r
+et des moustaches. À cette époque, des moustaches voulaient dire\r
+bourgeois et des éperons voulaient dire piéton.\r
+\r
+L'élégant de province portait les éperons plus longs et les moustaches\r
+plus farouches. C'était le temps de la lutte des républiques de\r
+l'Amérique méridionale contre le roi d'Espagne, de Bolivar contre\r
+Morillo. Les chapeaux à petits bords étaient royalistes et se nommaient\r
+des morillos; les libéraux portaient des chapeaux à larges bords qui\r
+s'appelaient des bolivars.\r
+\r
+Huit ou dix mois donc après ce qui a été raconté dans les pages\r
+précédentes, vers les premiers jours de janvier 1823, un soir qu'il\r
+avait neigé, un de ces élégants, un de ces désoeuvrés, un "bien\r
+pensant", car il avait un morillo, de plus chaudement enveloppé d'un de\r
+ces grands manteaux qui complétaient dans les temps froids le costume à\r
+la mode, se divertissait à harceler une créature qui rôdait en robe de\r
+bal et toute décolletée avec des fleurs sur la tête devant la vitre du\r
+café des officiers. Cet élégant fumait, car c'était décidément la mode.\r
+\r
+Chaque fois que cette femme passait devant lui, il lui jetait, avec une\r
+bouffée de la fumée de son cigare, quelque apostrophe qu'il croyait\r
+spirituelle et gaie, comme:--Que tu es laide!--Veux-tu te cacher!--Tu\r
+n'as pas de dents! etc., etc.--Ce monsieur s'appelait monsieur\r
+Bamatabois. La femme, triste spectre paré qui allait et venait sur la\r
+neige, ne lui répondait pas, ne le regardait même pas, et n'en\r
+accomplissait pas moins en silence et avec une régularité sombre sa\r
+promenade qui la ramenait de cinq minutes en cinq minutes sous le\r
+sarcasme, comme le soldat condamné qui revient sous les verges. Ce peu\r
+d'effet piqua sans doute l'oisif qui, profitant d'un moment où elle se\r
+retournait, s'avança derrière elle à pas de loup et en étouffant son\r
+rire, se baissa, prit sur le pavé une poignée de neige et la lui plongea\r
+brusquement dans le dos entre ses deux épaules nues. La fille poussa un\r
+rugissement, se tourna, bondit comme une panthère, et se rua sur\r
+l'homme, lui enfonçant ses ongles dans le visage, avec les plus\r
+effroyables paroles qui puissent tomber du corps de garde dans le\r
+ruisseau. Ces injures, vomies d'une voix enrouée par l'eau-de-vie,\r
+sortaient hideusement d'une bouche à laquelle manquaient en effet les\r
+deux dents de devant. C'était la Fantine.\r
+\r
+Au bruit que cela fit, les officiers sortirent en foule du café, les\r
+passants s'amassèrent, et il se forma un grand cercle riant, huant et\r
+applaudissant, autour de ce tourbillon composé de deux êtres où l'on\r
+avait peine à reconnaître un homme et une femme, l'homme se débattant,\r
+son chapeau à terre, la femme frappant des pieds et des poings,\r
+décoiffée, hurlant, sans dents et sans cheveux, livide de colère,\r
+horrible. Tout à coup un homme de haute taille sortit vivement de la\r
+foule, saisit la femme à son corsage de satin couvert de boue, et lui\r
+dit: Suis-moi!\r
+\r
+La femme leva la tête; sa voix furieuse s'éteignit subitement. Ses yeux\r
+étaient vitreux, de livide elle était devenue pâle, et elle tremblait\r
+d'un tremblement de terreur. Elle avait reconnu Javert.\r
+\r
+L'élégant avait profité de l'incident pour s'esquiver.\r

+Chapitre XIII\r
+\r
+Solution de quelques questions de police municipale\r
+\r
+\r
+Javert écarta les assistants, rompit le cercle et se mit à marcher à grands\r
+pas vers le bureau de police qui est à l'extrémité de la place, traînant\r
+après lui la misérable. Elle se laissait faire machinalement. Ni lui ni\r
+elle ne disaient un mot. La nuée des spectateurs, au paroxysme de la\r
+joie, suivait avec des quolibets. La suprême misère, occasion\r
+d'obscénités. Arrivé au bureau de police qui était une salle basse\r
+chauffée par un poêle et gardée par un poste, avec une porte vitrée et\r
+grillée sur la rue, Javert ouvrit la porte, entra avec Fantine, et\r
+referma la porte derrière lui, au grand désappointement des curieux qui\r
+se haussèrent sur la pointe du pied et allongèrent le cou devant la\r
+vitre trouble du corps de garde, cherchant à voir. La curiosité est une\r
+gourmandise. Voir, c'est dévorer.\r
+\r
+En entrant, la Fantine alla tomber dans un coin, immobile et muette,\r
+accroupie comme une chienne qui a peur.\r
+\r
+Le sergent du poste apporta une chandelle allumée sur une table. Javert\r
+s'assit, tira de sa poche une feuille de papier timbré et se mit à\r
+écrire.\r
+\r
+Ces classes de femmes sont entièrement remises par nos lois à la\r
+discrétion de la police. Elle en fait ce qu'elle veut, les punit comme\r
+bon lui semble, et confisque à son gré ces deux tristes choses qu'elles\r
+appellent leur industrie et leur liberté. Javert était impassible; son\r
+visage sérieux ne trahissait aucune émotion. Pourtant il était gravement\r
+et profondément préoccupé. C'était un de ces moments où il exerçait sans\r
+contrôle, mais avec tous les scrupules d'une conscience sévère, son\r
+redoutable pouvoir discrétionnaire. En cet instant, il le sentait, son\r
+escabeau d'agent de police était un tribunal. Il jugeait. Il jugeait, et\r
+il condamnait. Il appelait tout ce qu'il pouvait avoir d'idées dans\r
+l'esprit autour de la grande chose qu'il faisait. Plus il examinait le\r
+fait de cette fille, plus il se sentait révolté. Il était évident qu'il\r
+venait de voir commettre un crime. Il venait de voir, là dans la rue, la\r
+société, représentée par un propriétaire-électeur, insultée et attaquée\r
+par une créature en dehors de tout. Une prostituée avait attenté à un\r
+bourgeois. Il avait vu cela, lui Javert. Il écrivait en silence.\r
+\r
+Quand il eut fini, il signa, plia le papier et dit au sergent du poste,\r
+en le lui remettant:\r
+\r
+--Prenez trois hommes, et menez cette fille au bloc.\r
+\r
+Puis se tournant vers la Fantine:\r
+\r
+--Tu en as pour six mois.\r
+\r
+La malheureuse tressaillit.\r
+\r
+--Six mois! six mois de prison! Six mois à gagner sept sous par jour!\r
+Mais que deviendra Cosette? ma fille! ma fille! Mais je dois encore plus\r
+de cent francs aux Thénardier, monsieur l'inspecteur, savez-vous cela?\r
+\r
+Elle se traîna sur la dalle mouillée par les bottes boueuses de tous ces\r
+hommes, sans se lever, joignant les mains, faisant de grands pas avec\r
+ses genoux.\r
+\r
+--Monsieur Javert, dit-elle, je vous demande grâce. Je vous assure que\r
+je n'ai pas eu tort. Si vous aviez vu le commencement, vous auriez vu!\r
+je vous jure le bon Dieu que je n'ai pas eu tort. C'est ce monsieur le\r
+bourgeois que je ne connais pas qui m'a mis de la neige dans le dos.\r
+Est-ce qu'on a le droit de nous mettre de la neige dans le dos quand\r
+nous passons comme cela tranquillement sans faire de mal à personne?\r
+Cela m'a saisie. Je suis un peu malade, voyez-vous! Et puis il y avait\r
+déjà un peu de temps qu'il me disait des raisons. Tu es laide! tu n'as\r
+pas de dents! Je le sais bien que je n'ai plus mes dents. Je ne faisais\r
+rien, moi; je disais: c'est un monsieur qui s'amuse. J'étais honnête\r
+avec lui, je ne lui parlais pas. C'est à cet instant-là qu'il m'a mis de\r
+la neige. Monsieur Javert, mon bon monsieur l'inspecteur! est-ce qu'il\r
+n'y a personne là qui ait vu pour vous dire que c'est bien vrai? J'ai\r
+peut-être eu tort de me fâcher. Vous savez, dans le premier moment, on\r
+n'est pas maître. On a des vivacités. Et puis, quelque chose de si froid\r
+qu'on vous met dans le dos à l'heure que vous ne vous y attendez pas!\r
+J'ai eu tort d'abîmer le chapeau de ce monsieur. Pourquoi s'est-il en\r
+allé? Je lui demanderais pardon. Oh! mon Dieu, cela me serait bien égal\r
+de lui demander pardon. Faites-moi grâce pour aujourd'hui cette fois,\r
+monsieur Javert. Tenez, vous ne savez pas ça, dans les prisons on ne\r
+gagne que sept sous, ce n'est pas la faute du gouvernement, mais on\r
+gagne sept sous, et figurez-vous que j'ai cent francs à payer, ou\r
+autrement on me renverra ma petite. Ô mon Dieu! je ne peux pas l'avoir\r
+avec moi. C'est si vilain ce que je fais! Ô ma Cosette, ô mon petit ange\r
+de la bonne sainte Vierge, qu'est-ce qu'elle deviendra, pauvre loup! Je\r
+vais vous dire, c'est les Thénardier, des aubergistes, des paysans, ça\r
+n'a pas de raisonnement. Il leur faut de l'argent. Ne me mettez pas en\r
+prison! Voyez-vous, c'est une petite qu'on mettrait à même sur la grande\r
+route, va comme tu pourras, en plein coeur d'hiver, il faut avoir pitié\r
+de cette chose-là, mon bon monsieur Javert. Si c'était plus grand, ça\r
+gagnerait sa vie, mais ça ne peut pas, à ces âges-là. Je ne suis pas une\r
+mauvaise femme au fond. Ce n'est pas la lâcheté et la gourmandise qui\r
+ont fait de moi ça. J'ai bu de l'eau-de-vie, c'est par misère. Je ne\r
+l'aime pas, mais cela étourdit. Quand j'étais plus heureuse, on n'aurait\r
+eu qu'à regarder dans mes armoires, on aurait bien vu que je n'étais pas\r
+une femme coquette qui a du désordre. J'avais du linge, beaucoup de\r
+linge. Ayez pitié de moi, monsieur Javert!\r
+\r
+Elle parlait ainsi, brisée en deux, secouée par les sanglots, aveuglée\r
+par les larmes, la gorge nue, se tordant les mains, toussant d'une toux\r
+sèche et courte, balbutiant tout doucement avec la voix de l'agonie. La\r
+grande douleur est un rayon divin et terrible qui transfigure les\r
+misérables. À ce moment-là, la Fantine était redevenue belle. À de\r
+certains instants, elle s'arrêtait et baisait tendrement le bas de la\r
+redingote du mouchard. Elle eût attendri un coeur de granit, mais on\r
+n'attendrit pas un coeur de bois.\r
+\r
+--Allons! dit Javert, je t'ai écoutée. As-tu bien tout dit? Marche à\r
+présent! Tu as tes six mois; _le Père éternel en personne n'y pourrait\r
+plus rien_.\r
+\r
+À cette solennelle parole, Le Père éternel en personne n'y pourrait plus\r
+rien, elle comprit que l'arrêt était prononcé. Elle s'affaissa sur\r
+elle-même en murmurant:\r
+\r
+--Grâce!\r
+\r
+Javert tourna le dos.\r
+\r
+Les soldats la saisirent par les bras.\r
+\r
+Depuis quelques minutes, un homme était entré sans qu'on eût pris garde\r
+à lui. Il avait refermé la porte, s'y était adossé, et avait entendu les\r
+prières désespérées de la Fantine. Au moment où les soldats mirent la\r
+main sur la malheureuse, qui ne voulait pas se lever, il fit un pas,\r
+sortit de l'ombre, et dit:\r
+\r
+--Un instant, s'il vous plaît!\r
+\r
+Javert leva les yeux et reconnut M. Madeleine. Il ôta son chapeau, et\r
+saluant avec une sorte de gaucherie fâchée:\r
+\r
+--Pardon, monsieur le maire....\r
+\r
+Ce mot, monsieur le maire, fit sur la Fantine un effet étrange. Elle se\r
+dressa debout tout d'une pièce comme un spectre qui sort de terre,\r
+repoussa les soldats des deux bras, marcha droit à M. Madeleine avant\r
+qu'on eût pu la retenir, et le regardant fixement, l'air égaré, elle\r
+cria:\r
+\r
+--Ah! c'est donc toi qui es monsieur le maire!\r
+\r
+Puis elle éclata de rire et lui cracha au visage.\r
+\r
+M. Madeleine s'essuya le visage, et dit:\r
+\r
+--Inspecteur Javert, mettez cette femme en liberté.\r
+\r
+Javert se sentit au moment de devenir fou. Il éprouvait en cet instant,\r
+coup sur coup, et presque mêlées ensemble, les plus violentes émotions\r
+qu'il eût ressenties de sa vie. Voir une fille publique cracher au\r
+visage d'un maire, cela était une chose si monstrueuse que, dans ses\r
+suppositions les plus effroyables, il eût regardé comme un sacrilège de\r
+le croire possible. D'un autre côté, dans le fond de sa pensée, il\r
+faisait confusément un rapprochement hideux entre ce qu'était cette\r
+femme et ce que pouvait être ce maire, et alors il entrevoyait avec\r
+horreur je ne sais quoi de tout simple dans ce prodigieux attentat. Mais\r
+quand il vit ce maire, ce magistrat, s'essuyer tranquillement le visage\r
+et dire: _mettez cette femme en liberté_, il eut comme un éblouissement\r
+de stupeur; la pensée et la parole lui manquèrent également; la somme de\r
+l'étonnement possible était dépassée pour lui. Il resta muet.\r
+\r
+Ce mot n'avait pas porté un coup moins étrange à la Fantine. Elle leva\r
+son bras nu et se cramponna à la clef du poêle comme une personne qui\r
+chancelle. Cependant elle regardait tout autour d'elle et elle se mit à\r
+parler à voix basse, comme si elle se parlait à elle-même.\r
+\r
+--En liberté! qu'on me laisse aller! que je n'aille pas en prison six\r
+mois! Qui est-ce qui a dit cela? Il n'est pas possible qu'on ait dit\r
+cela. J'ai mal entendu. Ça ne peut pas être ce monstre de maire! Est-ce\r
+que c'est vous, mon bon monsieur Javert, qui avez dit qu'on me mette en\r
+liberté? Oh! voyez-vous! je vais vous dire et vous me laisserez aller.\r
+Ce monstre de maire, ce vieux gredin de maire, c'est lui qui est cause\r
+de tout. Figurez-vous, monsieur Javert, qu'il m'a chassée! à cause d'un\r
+tas de gueuses qui tiennent des propos dans l'atelier. Si ce n'est pas\r
+là une horreur! renvoyer une pauvre fille qui fait honnêtement son\r
+ouvrage! Alors je n'ai plus gagné assez, et tout le malheur est venu.\r
+D'abord il y a une amélioration que ces messieurs de la police devraient\r
+bien faire, ce serait d'empêcher les entrepreneurs des prisons de faire\r
+du tort aux pauvres gens. Je vais vous expliquer cela, voyez-vous. Vous\r
+gagnez douze sous dans les chemises, cela tombe à neuf sous, il n'y a\r
+plus moyen de vivre. Il faut donc devenir ce qu'on peut. Moi, j'avais ma\r
+petite Cosette, j'ai bien été forcée de devenir une mauvaise femme. Vous\r
+comprenez à présent, que c'est ce gueux de maire qui a tout fait le mal.\r
+Après cela, j'ai piétiné le chapeau de ce monsieur bourgeois devant le\r
+café des officiers. Mais lui, il m'avait perdu toute ma robe avec sa\r
+neige. Nous autres, nous n'avons qu'une robe de soie, pour le soir.\r
+Voyez-vous, je n'ai jamais fait de mal exprès, vrai, monsieur Javert, et\r
+je vois partout des femmes bien plus méchantes que moi qui sont bien\r
+plus heureuses. Ô monsieur Javert, c'est vous qui avez dit qu'on me\r
+mette dehors, n'est-ce pas? Prenez des informations, parlez à mon\r
+propriétaire, maintenant je paye mon terme, on vous dira bien que je\r
+suis honnête. Ah! mon Dieu, je vous demande pardon, j'ai touché, sans\r
+faire attention, à la clef du poêle, et cela fait fumer.\r
+\r
+M. Madeleine l'écoutait avec une attention profonde. Pendant qu'elle\r
+parlait, il avait fouillé dans son gilet, en avait tiré sa bourse et\r
+l'avait ouverte. Elle était vide. Il l'avait remise dans sa poche. Il\r
+dit à la Fantine:\r
+\r
+--Combien avez-vous dit que vous deviez?\r
+\r
+La Fantine, qui ne regardait que Javert, se retourna de son côté:\r
+\r
+--Est-ce que je te parle à toi!\r
+\r
+Puis s'adressant aux soldats:\r
+\r
+--Dites donc, vous autres, avez-vous vu comme je te vous lui ai craché à\r
+la figure? Ah! vieux scélérat de maire, tu viens ici pour me faire peur,\r
+mais je n'ai pas peur de toi. J'ai peur de monsieur Javert. J'ai peur de\r
+mon bon monsieur Javert!\r
+\r
+En parlant ainsi elle se retourna vers l'inspecteur:\r
+\r
+--Avec ça, voyez-vous, monsieur l'inspecteur, il faut être juste. Je\r
+comprends que vous êtes juste, monsieur l'inspecteur. Au fait, c'est\r
+tout simple, un homme qui joue à mettre un peu de neige dans le dos\r
+d'une femme, ça les faisait rire, les officiers, il faut bien qu'on se\r
+divertisse à quelque chose, nous autres nous sommes là pour qu'on\r
+s'amuse, quoi! Et puis, vous, vous venez, vous êtes bien forcé de mettre\r
+l'ordre, vous emmenez la femme qui a tort, mais en y réfléchissant,\r
+comme vous êtes bon, vous dites qu'on me mette en liberté, c'est pour la\r
+petite, parce que six mois en prison, cela m'empêcherait de nourrir mon\r
+enfant. Seulement n'y reviens plus, coquine! Oh! je n'y reviendrai plus,\r
+monsieur Javert! on me fera tout ce qu'on voudra maintenant, je ne\r
+bougerai plus. Seulement, aujourd'hui, voyez-vous, j'ai crié parce que\r
+cela m'a fait mal, je ne m'attendais pas du tout à cette neige de ce\r
+monsieur, et puis, je vous ai dit, je ne me porte pas très bien, je\r
+tousse, j'ai là dans l'estomac comme une boule qui me brûle, que le\r
+médecin me dit: soignez-vous. Tenez, tâtez, donnez votre main, n'ayez\r
+pas peur, c'est ici.\r
+\r
+Elle ne pleurait plus, sa voix était caressante, elle appuyait sur sa\r
+gorge blanche et délicate la grosse main rude de Javert, et elle le\r
+regardait en souriant.\r
+\r
+Tout à coup elle rajusta vivement le désordre de ses vêtements, fit\r
+retomber les plis de sa robe qui en se traînant s'était relevée presque\r
+à la hauteur du genou, et marcha vers la porte en disant à demi-voix aux\r
+soldats avec un signe de tête amical:\r
+\r
+--Les enfants, monsieur l'inspecteur a dit qu'on me lâche, je m'en vas.\r
+\r
+Elle mit la main sur le loquet. Un pas de plus, elle était dans la rue.\r
+\r
+Javert jusqu'à cet instant était resté debout, immobile, l'oeil fixé à\r
+terre, posé de travers au milieu de cette scène comme une statue\r
+dérangée qui attend qu'on la mette quelque part.\r
+\r
+Le bruit que fit le loquet le réveilla. Il releva la tête avec une\r
+expression d'autorité souveraine, expression toujours d'autant plus\r
+effrayante que le pouvoir se trouve placé plus bas, féroce chez la bête\r
+fauve, atroce chez l'homme de rien.\r
+\r
+--Sergent, cria-t-il, vous ne voyez pas que cette drôlesse s'en va! Qui\r
+est-ce qui vous a dit de la laisser aller?\r
+\r
+--Moi, dit Madeleine.\r
+\r
+La Fantine à la voix de Javert avait tremblé et lâché le loquet comme un\r
+voleur pris lâche l'objet volé. À la voix de Madeleine, elle se\r
+retourna, et à partir de ce moment, sans qu'elle prononçât un mot, sans\r
+qu'elle osât même laisser sortir son souffle librement, son regard alla\r
+tour à tour de Madeleine à Javert et de Javert à Madeleine, selon que\r
+c'était l'un ou l'autre qui parlait.\r
+\r
+Il était évident qu'il fallait que Javert eût été, comme on dit, «jeté\r
+hors des gonds» pour qu'il se fût permis d'apostropher le sergent comme\r
+il l'avait fait, après l'invitation du maire de mettre Fantine en\r
+liberté. En était-il venu à oublier la présence de monsieur le maire?\r
+Avait-il fini par se déclarer à lui-même qu'il était impossible qu'une\r
+«autorité» eût donné un pareil ordre, et que bien certainement monsieur\r
+le maire avait dû dire sans le vouloir une chose pour une autre? Ou\r
+bien, devant les énormités dont il était témoin depuis deux heures, se\r
+disait-il qu'il fallait revenir aux suprêmes résolutions, qu'il était\r
+nécessaire que le petit se fit grand, que le mouchard se transformât en\r
+magistrat, que l'homme de police devînt homme de justice, et qu'en cette\r
+extrémité prodigieuse l'ordre, la loi, la morale, le gouvernement, la\r
+société tout entière, se personnifiaient en lui Javert?\r
+\r
+Quoi qu'il en soit, quand M. Madeleine eut dit ce moi qu'on vient\r
+d'entendre, on vit l'inspecteur de police Javert se tourner vers\r
+monsieur le maire, pâle, froid, les lèvres bleues, le regard désespéré,\r
+tout le corps agité d'un tremblement imperceptible, et, chose inouïe,\r
+lui dire, l'oeil baissé, mais la voix ferme:\r
+\r
+--Monsieur le maire, cela ne se peut pas.\r
+\r
+--Comment? dit M. Madeleine.\r
+\r
+--Cette malheureuse a insulté un bourgeois.\r
+\r
+--Inspecteur Javert, repartit M. Madeleine avec un accent conciliant et\r
+calme, écoutez. Vous êtes un honnête homme, et je ne fais nulle\r
+difficulté de m'expliquer avec vous. Voici le vrai. Je passais sur la\r
+place comme vous emmeniez cette femme, il y avait encore des groupes, je\r
+me suis informé, j'ai tout su, c'est le bourgeois qui a eu tort et qui,\r
+en bonne police, eût dû être arrêté.\r
+\r
+Javert reprit:\r
+\r
+--Cette misérable vient d'insulter monsieur le maire.\r
+\r
+--Ceci me regarde, dit M. Madeleine. Mon injure est à moi peut-être.\r
+J'en puis faire ce que je veux.\r
+\r
+--Je demande pardon à monsieur le maire. Son injure n'est pas à lui,\r
+elle est à la justice.\r
+\r
+--Inspecteur Javert, répliqua M. Madeleine, la première justice, c'est\r
+la conscience. J'ai entendu cette femme. Je sais ce que je fais.\r
+\r
+--Et moi, monsieur le maire, je ne sais pas ce que je vois.\r
+\r
+--Alors contentez-vous d'obéir.\r
+\r
+--J'obéis à mon devoir. Mon devoir veut que cette femme fasse six mois\r
+de prison.\r
+\r
+M. Madeleine répondit avec douceur:\r
+\r
+--Écoutez bien ceci. Elle n'en fera pas un jour.\r
+\r
+À cette parole décisive, Javert osa regarder le maire fixement, et lui\r
+dit, mais avec un son de voix toujours profondément respectueux:\r
+\r
+--Je suis au désespoir de résister à monsieur le maire, c'est la\r
+première fois de ma vie, mais il daignera me permettre de lui faire\r
+observer que je suis dans la limite de mes attributions. Je reste,\r
+puisque monsieur le maire le veut, dans le fait du bourgeois. J'étais\r
+là. C'est cette fille qui s'est jetée sur monsieur Bamatabois, qui est\r
+électeur et propriétaire de cette belle maison à balcon qui fait le coin\r
+de l'esplanade, à trois étages et toute en pierre de taille. Enfin, il y\r
+a des choses dans ce monde! Quoi qu'il en soit, monsieur le maire, cela,\r
+c'est un fait de police de la rue qui me regarde, et je retiens la femme\r
+Fantine.\r
+\r
+Alors M. Madeleine croisa les bras et dit avec une voix sévère que\r
+personne dans la ville n'avait encore entendue:\r
+\r
+--Le fait dont vous parlez est un fait de police municipale. Aux termes\r
+des articles neuf, onze, quinze et soixante-six du code d'instruction\r
+criminelle, j'en suis juge. J'ordonne que cette femme soit mise en\r
+liberté.\r
+\r
+Javert voulut tenter un dernier effort.\r
+\r
+--Mais, monsieur le maire....\r
+\r
+--Je vous rappelle, à vous, l'article quatre-vingt-un de la loi du 13\r
+décembre 1799 sur la détention arbitraire.\r
+\r
+--Monsieur le maire, permettez....\r
+\r
+--Plus un mot.\r
+\r
+--Pourtant....\r
+\r
+--Sortez, dit M. Madeleine.\r
+\r
+Javert reçut le coup, debout, de face, et en pleine poitrine comme un\r
+soldat russe. Il salua jusqu'à terre monsieur le maire, et sortit.\r
+\r
+Fantine se rangea de la porte et le regarda avec stupeur passer devant\r
+elle.\r
+\r
+Cependant elle aussi était en proie à un bouleversement étrange. Elle\r
+venait de se voir en quelque sorte disputée par deux puissances\r
+opposées. Elle avait vu lutter devant ses yeux deux hommes tenant dans\r
+leurs mains sa liberté, sa vie, son âme, son enfant; l'un de ces hommes\r
+la tirait du côté de l'ombre, l'autre la ramenait vers la lumière. Dans\r
+cette lutte, entrevue à travers les grossissements de l'épouvante, ces\r
+deux hommes lui étaient apparus comme deux géants; l'un parlait comme\r
+son démon, l'autre parlait comme son bon ange. L'ange avait vaincu le\r
+démon, et, chose qui la faisait frissonner de la tête aux pieds, cet\r
+ange, ce libérateur, c'était précisément l'homme qu'elle abhorrait, ce\r
+maire qu'elle avait si longtemps considéré comme l'auteur de tous ses\r
+maux, ce Madeleine! et au moment même où elle venait de l'insulter d'une\r
+façon hideuse, il la sauvait! S'était-elle donc trompée? Devait-elle\r
+donc changer toute son âme?... Elle ne savait, elle tremblait. Elle\r
+écoutait éperdue, elle regardait effarée, et à chaque parole que disait\r
+M. Madeleine, elle sentait fondre et s'écrouler en elle les affreuses\r
+ténèbres de la haine et naître dans son coeur je ne sais quoi de\r
+réchauffant et d'ineffable qui était de la joie, de la confiance et de\r
+l'amour.\r
+\r
+Quand Javert fut sorti, M. Madeleine se tourna vers elle, et lui dit\r
+avec une voix lente, ayant peine à parler comme un homme sérieux qui ne\r
+veut pas pleurer:\r
+\r
+--Je vous ai entendue. Je ne savais rien de ce que vous avez dit. Je\r
+crois que c'est vrai, et je sens que c'est vrai. J'ignorais même que\r
+vous eussiez quitté mes ateliers. Pourquoi ne vous êtes-vous pas\r
+adressée à moi? Mais voici: je payerai vos dettes, je ferai venir votre\r
+enfant, ou vous irez la rejoindre. Vous vivrez ici, à Paris, où vous\r
+voudrez. Je me charge de votre enfant et de vous. Vous ne travaillerez\r
+plus, si vous voulez. Je vous donnerai tout l'argent qu'il vous faudra.\r
+Vous redeviendrez honnête en redevenant heureuse. Et même, écoutez, je\r
+vous le déclare dès à présent, si tout est comme vous le dites, et je\r
+n'en doute pas, vous n'avez jamais cessé d'être vertueuse et sainte\r
+devant Dieu. Oh! pauvre femme!\r
+\r
+C'en était plus que la pauvre Fantine n'en pouvait supporter. Avoir\r
+Cosette! sortir de cette vie infâme! vivre libre, riche, heureuse,\r
+honnête, avec Cosette! voir brusquement s'épanouir au milieu de sa\r
+misère toutes ces réalités du paradis! Elle regarda comme hébétée cet\r
+homme qui lui parlait, et ne put que jeter deux ou trois sanglots: oh!\r
+oh! oh! Ses jarrets plièrent, elle se mit à genoux devant M. Madeleine,\r
+et, avant qu'il eût pu l'en empêcher, il sentit qu'elle lui prenait la\r
+main et que ses lèvres s'y posaient.\r
+\r
+Puis elle s'évanouit.\r

+\r
+Livre sixième--Javert\r
+\r
+\r
+\r
+\r
+Chapitre I\r
+\r
+Commencement du repos\r
+\r
+\r
+M. Madeleine fit transporter la Fantine à cette infirmerie qu'il avait\r
+dans sa propre maison. Il la confia aux soeurs qui la mirent au lit. Une\r
+fièvre ardente était survenue. Elle passa une partie de la nuit à\r
+délirer et à parler haut. Cependant elle finit par s'endormir.\r
+\r
+Le lendemain vers midi Fantine se réveilla, elle entendit une\r
+respiration tout près de son lit, elle écarta son rideau et vit M.\r
+Madeleine debout qui regardait quelque chose au-dessus de sa tête. Ce\r
+regard était plein de pitié et d'angoisse et suppliait. Elle en suivit\r
+la direction et vit qu'il s'adressait à un crucifix cloué au mur.\r
+\r
+M. Madeleine était désormais transfiguré aux yeux de Fantine. Il lui\r
+paraissait enveloppé de lumière. Il était absorbé dans une sorte de\r
+prière. Elle le considéra longtemps sans oser l'interrompre. Enfin elle\r
+lui dit timidement:\r
+\r
+--Que faites-vous donc là?\r
+\r
+M. Madeleine était à cette place depuis une heure. Il attendait que\r
+Fantine se réveillât. Il lui prit la main, lui tâta le pouls, et\r
+répondit:\r
+\r
+--Comment êtes-vous?\r
+\r
+--Bien, j'ai dormi, dit-elle, je crois que je vais mieux. Ce ne sera\r
+rien.\r
+\r
+Lui reprit, répondant à la question qu'elle lui avait adressée d'abord,\r
+comme s'il ne faisait que de l'entendre:\r
+\r
+--Je priais le martyr qui est là-haut.\r
+\r
+Et il ajouta dans sa pensée: «Pour la martyre qui est ici-bas.»\r
+\r
+M. Madeleine avait passé la nuit et la matinée à s'informer. Il savait\r
+tout maintenant. Il connaissait dans tous ses poignants détails\r
+l'histoire de Fantine. Il continua:\r
+\r
+--Vous avez bien souffert, pauvre mère. Oh! ne vous plaignez pas, vous\r
+avez à présent la dot des élus. C'est de cette façon que les hommes font\r
+des anges. Ce n'est point leur faute; ils ne savent pas s'y prendre\r
+autrement. Voyez-vous, cet enfer dont vous sortez est la première forme\r
+du ciel. Il fallait commencer par là.\r
+\r
+Il soupira profondément. Elle cependant lui souriait avec ce sublime\r
+sourire auquel il manquait deux dents.\r
+\r
+Javert dans cette même nuit avait écrit une lettre. Il remit lui-même\r
+cette lettre le lendemain matin au bureau de poste de Montreuil-sur-mer.\r
+Elle était pour Paris, et la suscription portait: À _monsieur\r
+Chabouillet, secrétaire de monsieur le préfet de police_. Comme\r
+l'affaire du corps de garde s'était ébruitée, la directrice du bureau de\r
+poste et quelques autres personnes qui virent la lettre avant le départ\r
+et qui reconnurent l'écriture de Javert sur l'adresse, pensèrent que\r
+c'était sa démission qu'il envoyait.\r
+\r
+M. Madeleine se hâta d'écrire aux Thénardier. Fantine leur devait cent\r
+vingt francs. Il leur envoya trois cents francs en leur disant de se\r
+payer sur cette somme, et d'amener tout de suite l'enfant à\r
+Montreuil-sur-mer où sa mère malade la réclamait.\r
+\r
+Ceci éblouit le Thénardier.\r
+\r
+--Diable! dit-il à sa femme, ne lâchons pas l'enfant. Voilà que cette\r
+mauviette va devenir une vache à lait. Je devine. Quelque jocrisse se\r
+sera amouraché de la mère.\r
+\r
+Il riposta par un mémoire de cinq cents et quelques francs fort bien\r
+fait. Dans ce mémoire figuraient pour plus de trois cents francs deux\r
+notes incontestables, l'une d'un médecin, l'autre d'un apothicaire,\r
+lesquels avaient soigné et médicamenté dans deux longues maladies\r
+Éponine et Azelma. Cosette, nous l'avons dit, n'avait pas été malade. Ce\r
+fut l'affaire d'une toute petite substitution de noms. Thénardier mit au\r
+bas du mémoire: _reçu à compte trois cents francs_.\r
+\r
+M. Madeleine envoya tout de suite trois cents autres francs et écrivit:\r
+Dépêchez-vous d'amener Cosette.\r
+\r
+--Christi! dit le Thénardier, ne lâchons pas l'enfant.\r
+\r
+Cependant Fantine ne se rétablissait point. Elle était toujours à\r
+l'infirmerie. Les soeurs n'avaient d'abord reçu et soigné «cette fille»\r
+qu'avec répugnance. Qui a vu les bas-reliefs de Reims se souvient du\r
+gonflement de la lèvre inférieure des vierges sages regardant les\r
+vierges folles. Cet antique mépris des vestales pour les ambulaïes est\r
+un des plus profonds instincts de la dignité féminine; les soeurs\r
+l'avaient éprouvé, avec le redoublement qu'ajoute la religion. Mais, en\r
+peu de jours, Fantine les avait désarmées. Elle avait toutes sortes de\r
+paroles humbles et douces, et la mère qui était en elle attendrissait.\r
+Un jour les soeurs l'entendirent qui disait à travers la fièvre:\r
+\r
+--J'ai été une pécheresse, mais quand j'aurai mon enfant près de moi,\r
+cela voudra dire que Dieu m'a pardonné. Pendant que j'étais dans le mal,\r
+je n'aurais pas voulu avoir ma Cosette avec moi, je n'aurais pas pu\r
+supporter ses yeux étonnés et tristes. C'était pour elle pourtant que je\r
+faisais le mal, et c'est ce qui fait que Dieu me pardonne. Je sentirai\r
+la bénédiction du bon Dieu quand Cosette sera ici. Je la regarderai,\r
+cela me fera du bien de voir cette innocente. Elle ne sait rien du tout.\r
+C'est un ange, voyez-vous, mes soeurs. À cet âge-là, les ailes, ça n'est\r
+pas encore tombé.\r
+\r
+M. Madeleine l'allait voir deux fois par jour, et chaque fois elle lui\r
+demandait:\r
+\r
+--Verrai-je bientôt ma Cosette?\r
+\r
+Il lui répondait:\r
+\r
+--Peut-être demain matin. D'un moment à l'autre elle arrivera, je\r
+l'attends.\r
+\r
+Et le visage pâle de la mère rayonnait.\r
+\r
+--Oh! disait-elle, comme je vais être heureuse!\r
+\r
+Nous venons de dire qu'elle ne se rétablissait pas. Au contraire, son\r
+état semblait s'aggraver de semaine en semaine. Cette poignée de neige\r
+appliquée à nu sur la peau entre les deux omoplates avait déterminé une\r
+suppression subite de transpiration à la suite de laquelle la maladie\r
+qu'elle couvait depuis plusieurs années finit par se déclarer\r
+violemment. On commençait alors à suivre pour l'étude et le traitement\r
+des maladies de poitrine les belles indications de Laennec. Le médecin\r
+ausculta Fantine et hocha la tête.\r
+\r
+M. Madeleine dit au médecin:\r
+\r
+--Eh bien?\r
+\r
+--N'a-t-elle pas un enfant qu'elle désire voir? dit le médecin.\r
+\r
+--Oui.\r
+\r
+--Eh bien, hâtez-vous de le faire venir.\r
+\r
+M. Madeleine eut un tressaillement.\r
+\r
+Fantine lui demanda:\r
+\r
+--Qu'a dit le médecin?\r
+\r
+M. Madeleine s'efforça de sourire.\r
+\r
+--Il a dit de faire venir bien vite votre enfant. Que cela vous rendra\r
+la santé.\r
+\r
+--Oh! reprit-elle, il a raison! Mais qu'est-ce qu'ils ont donc ces\r
+Thénardier à me garder ma Cosette! Oh! elle va venir. Voici enfin que je\r
+vois le bonheur tout près de moi!\r
+\r
+Le Thénardier cependant ne «lâchait pas l'enfant» et donnait cent\r
+mauvaises raisons. Cosette était un peu souffrante pour se mettre en\r
+route l'hiver. Et puis il y avait un reste de petites dettes criardes\r
+dans le pays dont il rassemblait les factures, etc., etc.\r
+\r
+--J'enverrai quelqu'un chercher Cosette, dit le père Madeleine. S'il le\r
+faut, j'irai moi-même.\r
+\r
+Il écrivit sous la dictée de Fantine cette lettre qu'il lui fit signer:\r
+\r
+«Monsieur Thénardier,\r
+\r
+«Vous remettrez Cosette à la personne.\r
+\r
+«On vous payera toutes les petites choses.\r
+\r
+«J'ai l'honneur de vous saluer avec considération.\r
+\r
+«Fantine.»\r
+\r
+Sur ces entrefaites, il survint un grave incident. Nous avons beau\r
+tailler de notre mieux le bloc mystérieux dont notre vie est faite, la\r
+veine noire de la destinée y reparaît toujours.\r

+\r
+Chapitre II\r
+\r
+Comment Jean peut devenir Champ\r
+\r
+\r
+Un matin, M. Madeleine était dans son cabinet, occupé à régler d'avance\r
+quelques affaires pressantes de la mairie pour le cas où il se\r
+déciderait à ce voyage de Montfermeil, lorsqu'on vint lui dire que\r
+l'inspecteur de police Javert demandait à lui parler. En entendant\r
+prononcer ce nom, M. Madeleine ne put se défendre d'une impression\r
+désagréable. Depuis l'aventure du bureau de police, Javert l'avait plus\r
+que jamais évité, et M. Madeleine ne l'avait point revu.\r
+\r
+--Faites entrer, dit-il.\r
+\r
+Javert entra.\r
+\r
+M. Madeleine était resté assis près de la cheminée, une plume à la main,\r
+l'oeil sur un dossier qu'il feuilletait et qu'il annotait, et qui\r
+contenait des procès-verbaux de contraventions à la police de la voirie.\r
+Il ne se dérangea point pour Javert. Il ne pouvait s'empêcher de songer\r
+à la pauvre Fantine, et il lui convenait d'être glacial.\r
+\r
+Javert salua respectueusement M. le maire qui lui tournait le dos. M. le\r
+maire ne le regarda pas et continua d'annoter son dossier.\r
+\r
+Javert fit deux ou trois pas dans le cabinet, et s'arrêta sans rompre le\r
+silence. Un physionomiste qui eût été familier avec la nature de Javert,\r
+qui eût étudié depuis longtemps ce sauvage au service de la\r
+civilisation, ce composé bizarre du Romain, du Spartiate, du moine et du\r
+caporal, cet espion incapable d'un mensonge, ce mouchard vierge, un\r
+physionomiste qui eût su sa secrète et ancienne aversion pour M.\r
+Madeleine, son conflit avec le maire au sujet de la Fantine, et qui eût\r
+considéré Javert en ce moment, se fût dit: que s'est-il passé? Il était\r
+évident, pour qui eût connu cette conscience droite, claire, sincère,\r
+probe, austère et féroce, que Javert sortait de quelque grand événement\r
+intérieur. Javert n'avait rien dans l'âme qu'il ne l'eût aussi sur le\r
+visage. Il était, comme les gens violents, sujet aux revirements\r
+brusques. Jamais sa physionomie n'avait été plus étrange et plus\r
+inattendue. En entrant, il s'était incliné devant M. Madeleine avec un\r
+regard où il n'y avait ni rancune, ni colère, ni défiance, il s'était\r
+arrêté à quelques pas derrière le fauteuil du maire; et maintenant il se\r
+tenait là, debout, dans une attitude presque disciplinaire, avec la\r
+rudesse naïve et froide d'un homme qui n'a jamais été doux et qui a\r
+toujours été patient; il attendait, sans dire un mot, sans faire un\r
+mouvement, dans une humilité vraie et dans une résignation tranquille,\r
+qu'il plût à monsieur le maire de se retourner, calme, sérieux, le\r
+chapeau à la main, les yeux baissés, avec une expression qui tenait le\r
+milieu entre le soldat devant son officier et le coupable devant son\r
+juge. Tous les sentiments comme tous les souvenirs qu'on eût pu lui\r
+supposer avaient disparu. Il n'y avait plus rien sur ce visage\r
+impénétrable et simple comme le granit, qu'une morne tristesse. Toute sa\r
+personne respirait l'abaissement et la fermeté, et je ne sais quel\r
+accablement courageux.\r
+\r
+Enfin M. le maire posa sa plume et se tourna à demi.\r
+\r
+--Eh bien! qu'est-ce? qu'y a-t-il, Javert?\r
+\r
+Javert demeura un instant silencieux comme s'il se recueillait, puis\r
+éleva la voix avec une sorte de solennité triste qui n'excluait pourtant\r
+pas la simplicité:\r
+\r
+--Il y a, monsieur le maire, qu'un acte coupable a été commis.\r
+\r
+--Quel acte?\r
+\r
+--Un agent inférieur de l'autorité a manqué de respect à un magistrat de\r
+la façon la plus grave. Je viens, comme c'est mon devoir, porter le fait\r
+à votre connaissance.\r
+\r
+--Quel est cet agent? demanda M. Madeleine.\r
+\r
+--Moi, dit Javert.\r
+\r
+--Vous?\r
+\r
+--Moi.\r
+\r
+--Et quel est le magistrat qui aurait à se plaindre de l'agent?\r
+\r
+--Vous, monsieur le maire.\r
+\r
+M. Madeleine se dressa sur son fauteuil. Javert poursuivit, l'air sévère\r
+et les yeux toujours baissés:\r
+\r
+--Monsieur le maire, je viens vous prier de vouloir bien provoquer près\r
+de l'autorité ma destitution.\r
+\r
+M. Madeleine stupéfait ouvrit la bouche. Javert l'interrompit.\r
+\r
+--Vous direz, j'aurais pu donner ma démission, mais cela ne suffit pas.\r
+Donner sa démission, c'est honorable. J'ai failli, je dois être puni. Il\r
+faut que je sois chassé.\r
+\r
+Et après une pause, il ajouta:\r
+\r
+--Monsieur le maire, vous avez été sévère pour moi l'autre jour\r
+injustement. Soyez-le aujourd'hui justement.\r
+\r
+--Ah çà! pourquoi? s'écria M. Madeleine. Quel est ce galimatias?\r
+qu'est-ce que cela veut dire? où y a-t-il un acte coupable commis contre\r
+moi par vous? qu'est-ce que vous m'avez fait? quels torts avez-vous\r
+envers moi? Vous vous accusez, vous voulez être remplacé....\r
+\r
+--Chassé, dit Javert.\r
+\r
+--Chassé, soit. C'est fort bien. Je ne comprends pas.\r
+\r
+--Vous allez comprendre, monsieur le maire.\r
+\r
+Javert soupira du fond de sa poitrine et reprit toujours froidement et\r
+tristement:\r
+\r
+--Monsieur le maire, il y a six semaines, à la suite de cette scène pour\r
+cette fille, j'étais furieux, je vous ai dénoncé.\r
+\r
+--Dénoncé!\r
+\r
+--À la préfecture de police de Paris.\r
+\r
+M. Madeleine, qui ne riait pas beaucoup plus souvent que Javert, se mit\r
+à rire.\r
+\r
+--Comme maire ayant empiété sur la police?\r
+\r
+--Comme ancien forçat.\r
+\r
+Le maire devint livide.\r
+\r
+Javert, qui n'avait pas levé les yeux, continua:\r
+\r
+--Je le croyais. Depuis longtemps j'avais des idées.\r
+\r
+Une ressemblance, des renseignements que vous avez fait prendre à\r
+Faverolles, votre force des reins, l'aventure du vieux Fauchelevent,\r
+votre adresse au tir, votre jambe qui traîne un peu, est-ce que je sais,\r
+moi? des bêtises! mais enfin je vous prenais pour un nommé Jean Valjean.\r
+\r
+--Un nommé?... Comment dites-vous ce nom-là?\r
+\r
+--Jean Valjean. C'est un forçat que j'avais vu il y a vingt ans quand\r
+j'étais adjudant-garde-chiourme à Toulon. En sortant du bagne, ce Jean\r
+Valjean avait, à ce qu'il paraît, volé chez un évêque, puis il avait\r
+commis un autre vol à main armée, dans un chemin public, sur un petit\r
+savoyard. Depuis huit ans il s'était dérobé, on ne sait comment, et on\r
+le cherchait. Moi je m'étais figuré... Enfin, j'ai fait cette chose! La\r
+colère m'a décidé, je vous ai dénoncé à la préfecture.\r
+\r
+M. Madeleine, qui avait ressaisi le dossier depuis quelques instants,\r
+reprit avec un accent de parfaite indifférence:\r
+\r
+--Et que vous a-t-on répondu?\r
+\r
+--Que j'étais fou.\r
+\r
+--Eh bien?\r
+\r
+--Eh bien, on avait raison.\r
+\r
+--C'est heureux que vous le reconnaissiez!\r
+\r
+--Il faut bien, puisque le véritable Jean Valjean est trouvé.\r
+\r
+La feuille que tenait M. Madeleine lui échappa des mains, il leva la\r
+tête, regarda fixement Javert, et dit avec un accent inexprimable:\r
+\r
+--Ah!\r
+\r
+Javert poursuivit:\r
+\r
+--Voilà ce que c'est, monsieur le maire. Il paraît qu'il y avait dans le\r
+pays, du côté d'Ailly-le-Haut-Clocher, une espèce de bonhomme qu'on\r
+appelait le père Champmathieu. C'était très misérable. On n'y faisait\r
+pas attention. Ces gens-là, on ne sait pas de quoi cela vit.\r
+Dernièrement, cet automne, le père Champmathieu a été arrêté pour un vol\r
+de pommes à cidre, commis chez...--enfin n'importe! Il y a eu vol, mur\r
+escaladé, branches de l'arbre cassées. On a arrêté mon Champmathieu. Il\r
+avait encore la branche de pommier à la main. On coffre le drôle.\r
+Jusqu'ici ce n'est pas beaucoup plus qu'une affaire correctionnelle.\r
+Mais voici qui est de la providence. La geôle étant en mauvais état,\r
+monsieur le juge d'instruction trouve à propos de faire transférer\r
+Champmathieu à Arras où est la prison départementale. Dans cette prison\r
+d'Arras, il y a un ancien forçat nommé Brevet qui est détenu pour je ne\r
+sais quoi et qu'on a fait guichetier de chambrée parce qu'il se conduit\r
+bien. Monsieur le maire, Champmathieu n'est pas plus tôt débarqué que\r
+voilà Brevet qui s'écrie: «Eh mais! je connais cet homme-là. C'est un\r
+fagot. Regardez-moi donc, bonhomme! Vous êtes Jean Valjean!--Jean\r
+Valjean! qui ça Jean Valjean? Le Champmathieu joue l'étonné.--Ne fais\r
+donc pas le sinvre, dit Brevet. Tu es Jean Valjean! Tu as été au bagne\r
+de Toulon. Il y a vingt ans. Nous y étions ensemble.--Le Champmathieu\r
+nie. Parbleu! vous comprenez. On approfondit. On me fouille cette\r
+aventure-là. Voici ce qu'on trouve: ce Champmathieu, il y a une\r
+trentaine d'années, a été ouvrier émondeur d'arbres dans plusieurs pays,\r
+notamment à Faverolles. Là on perd sa trace. Longtemps après, on le\r
+revoit en Auvergne, puis à Paris, où il dit avoir été charron et avoir\r
+eu une fille blanchisseuse, mais cela n'est pas prouvé; enfin dans ce\r
+pays-ci. Or, avant d'aller au bagne pour vol qualifié, qu'était Jean\r
+Valjean? émondeur. Où? à Faverolles. Autre fait. Ce Valjean s'appelait\r
+de son nom de baptême Jean et sa mère se nommait de son nom de famille\r
+Mathieu. Quoi de plus naturel que de penser qu'en sortant du bagne il\r
+aura pris le nom de sa mère pour se cacher et se sera fait appeler Jean\r
+Mathieu? Il va en Auvergne. De _Jean_ la prononciation du pays fait\r
+_Chan_, on l'appelle Chan Mathieu. Notre homme se laisse faire et le\r
+voilà transformé en Champmathieu. Vous me suivez, n'est-ce pas? On\r
+s'informe à Faverolles. La famille de Jean Valjean n'y est plus. On ne\r
+sait plus où elle est. Vous savez, dans ces classes-là, il y a souvent\r
+de ces évanouissements d'une famille. On cherche, on ne trouve plus\r
+rien. Ces gens-là, quand ce n'est pas de la boue, c'est de la poussière.\r
+Et puis, comme le commencement de ces histoires date de trente ans, il\r
+n'y a plus personne à Faverolles qui ait connu Jean Valjean. On\r
+s'informe à Toulon. Avec Brevet, il n'y a plus que deux forçats qui\r
+aient vu Jean Valjean. Ce sont les condamnés à vie Cochepaille et\r
+Chenildieu. On les extrait du bagne et on les fait venir. On les\r
+confronte au prétendu Champmathieu. Ils n'hésitent pas. Pour eux comme\r
+pour Brevet, c'est Jean Valjean. Même âge, il a cinquante-quatre ans,\r
+même taille, même air, même homme enfin, c'est lui. C'est en ce\r
+moment-là même que j'envoyais ma dénonciation à la préfecture de Paris.\r
+On me répond que je perds l'esprit et que Jean Valjean est à Arras au\r
+pouvoir de la justice. Vous concevez si cela m'étonne, moi qui croyais\r
+tenir ici ce même Jean Valjean! J'écris à monsieur le juge\r
+d'instruction. Il me fait venir, on m'amène le Champmathieu....\r
+\r
+--Eh bien? interrompit M. Madeleine.\r
+\r
+Javert répondit avec son visage incorruptible et triste:\r
+\r
+--Monsieur le maire, la vérité est la vérité. J'en suis fâché, mais\r
+c'est cet homme-là qui est Jean Valjean. Moi aussi je l'ai reconnu.\r
+\r
+M. Madeleine reprit d'une voix très basse:\r
+\r
+--Vous êtes sûr?\r
+\r
+Javert se mit à rire de ce rire douloureux qui échappe à une conviction\r
+profonde:\r
+\r
+--Oh, sûr!\r
+\r
+Il demeura un moment pensif, prenant machinalement des pincées de poudre\r
+de bois dans la sébille à sécher l'encre qui était sur la table, et il\r
+ajouta:\r
+\r
+--Et même, maintenant que je vois le vrai Jean Valjean, je ne comprends\r
+pas comment j'ai pu croire autre chose. Je vous demande pardon, monsieur\r
+le maire.\r
+\r
+En adressant cette parole suppliante et grave à celui qui, six semaines\r
+auparavant, l'avait humilié en plein corps de garde et lui avait dit:\r
+«sortez!» Javert, cet homme hautain, était à son insu plein de\r
+simplicité et de dignité. M. Madeleine ne répondit à sa prière que par\r
+cette question brusque:\r
+\r
+--Et que dit cet homme?\r
+\r
+--Ah, dame! monsieur le maire, l'affaire est mauvaise. Si c'est Jean\r
+Valjean, il y a récidive. Enjamber un mur, casser une branche, chiper\r
+des pommes, pour un enfant, c'est une polissonnerie; pour un homme,\r
+c'est un délit; pour un forçat, c'est un crime. Escalade et vol, tout y\r
+est. Ce n'est plus la police correctionnelle, c'est la cour d'assises.\r
+Ce n'est plus quelques jours de prison, ce sont les galères à\r
+perpétuité. Et puis, il y a l'affaire du petit savoyard que j'espère\r
+bien qui reviendra. Diable! il y a de quoi se débattre, n'est-ce pas?\r
+Oui, pour un autre que Jean Valjean. Mais Jean Valjean est un sournois.\r
+C'est encore là que je le reconnais. Un autre sentirait que cela\r
+chauffe; il se démènerait, il crierait, la bouilloire chante devant le\r
+feu, il ne voudrait pas être Jean Valjean, et caetera. Lui, il n'a pas\r
+l'air de comprendre, il dit: Je suis Champmathieu, je ne sors pas de là!\r
+Il a l'air étonné, il fait la brute, c'est bien mieux. Oh! le drôle est\r
+habile. Mais c'est égal, les preuves sont là. Il est reconnu par quatre\r
+personnes, le vieux coquin sera condamné. C'est porté aux assises, à\r
+Arras. Je vais y aller pour témoigner. Je suis cité.\r
+\r
+M. Madeleine s'était remis à son bureau, avait ressaisi son dossier, et\r
+le feuilletait tranquillement, lisant et écrivant tour à tour comme un\r
+homme affairé. Il se tourna vers Javert:\r
+\r
+--Assez, Javert. Au fait, tous ces détails m'intéressent fort peu. Nous\r
+perdons notre temps, et nous avons des affaires pressées. Javert, vous\r
+allez vous rendre sur-le-champ chez la bonne femme Buseaupied qui vend\r
+des herbes là-bas au coin de la rue Saint-Saulve. Vous lui direz de\r
+déposer sa plainte contre le charretier Pierre Chesnelong. Cet homme est\r
+un brutal qui a failli écraser cette femme et son enfant. Il faut qu'il\r
+soit puni. Vous irez ensuite chez M. Charcellay, rue\r
+Montre-de-Champigny. Il se plaint qu'il y a une gouttière de la maison\r
+voisine qui verse l'eau de la pluie chez lui, et qui affouille les\r
+fondations de sa maison. Après vous constaterez des contraventions de\r
+police qu'on me signale rue Guibourg chez la veuve Doris, et rue du\r
+Garraud-Blanc chez madame Renée Le Bossé, et vous dresserez\r
+procès-verbal. Mais je vous donne là beaucoup de besogne. N'allez-vous\r
+pas être absent? ne m'avez-vous pas dit que vous alliez à Arras pour\r
+cette affaire dans huit ou dix jours?...\r
+\r
+--Plus tôt que cela, monsieur le maire.\r
+\r
+--Quel jour donc?\r
+\r
+--Mais je croyais avoir dit à monsieur le maire que cela se jugeait\r
+demain et que je partais par la diligence cette nuit.\r
+\r
+M. Madeleine fit un mouvement imperceptible.\r
+\r
+--Et combien de temps durera l'affaire?\r
+\r
+--Un jour tout au plus. L'arrêt sera prononcé au plus tard demain dans\r
+la nuit. Mais je n'attendrai pas l'arrêt, qui ne peut manquer. Sitôt ma\r
+déposition faite, je reviendrai ici.\r
+\r
+--C'est bon, dit M. Madeleine.\r
+\r
+Et il congédia Javert d'un signe de main. Javert ne s'en alla pas.\r
+\r
+--Pardon, monsieur le maire, dit-il.\r
+\r
+--Qu'est-ce encore? demanda M. Madeleine.\r
+\r
+--Monsieur le maire, il me reste une chose à vous rappeler.\r
+\r
+--Laquelle?\r
+\r
+--C'est que je dois être destitué.\r
+\r
+M. Madeleine se leva.\r
+\r
+--Javert, vous êtes un homme d'honneur, et je vous estime. Vous vous\r
+exagérez votre faute. Ceci d'ailleurs est encore une offense qui me\r
+concerne. Javert, vous êtes digne de monter et non de descendre.\r
+J'entends que vous gardiez votre place.\r
+\r
+Javert regarda M. Madeleine avec sa prunelle candide au fond de laquelle\r
+il semblait qu'on vit cette conscience peu éclairée, mais rigide et\r
+chaste, et il dit d'une voix tranquille:\r
+\r
+--Monsieur le maire, je ne puis vous accorder cela.\r
+\r
+--Je vous répète, répliqua M. Madeleine, que la chose me regarde.\r
+\r
+Mais Javert, attentif à sa seule pensée, continua:\r
+\r
+--Quant à exagérer, je n'exagère point. Voici comment je raisonne. Je\r
+vous ai soupçonné injustement. Cela, ce n'est rien. C'est notre droit à\r
+nous autres de soupçonner, quoiqu'il y ait pourtant abus à soupçonner\r
+au-dessus de soi. Mais, sans preuves, dans un accès de colère, dans le\r
+but de me venger, je vous ai dénoncé comme forçat, vous, un homme\r
+respectable, un maire, un magistrat! ceci est grave. Très grave. J'ai\r
+offensé l'autorité dans votre personne, moi, agent de l'autorité! Si\r
+l'un de mes subordonnés avait fait ce que j'ai fait, je l'aurais déclaré\r
+indigne du service, et chassé. Eh bien?\r
+\r
+Tenez, monsieur le maire, encore un mot. J'ai souvent été sévère dans ma\r
+vie. Pour les autres. C'était juste. Je faisais bien. Maintenant, si je\r
+n'étais pas sévère pour moi, tout ce que j'ai fait de juste deviendrait\r
+injuste.\r
+\r
+Est-ce que je dois m'épargner plus que les autres? Non. Quoi! je\r
+n'aurais été bon qu'à châtier autrui, et pas moi! mais je serais un\r
+misérable! mais ceux qui disent: ce gueux de Javert! auraient raison!\r
+Monsieur le maire, je ne souhaite pas que vous me traitiez avec bonté,\r
+votre bonté m'a fait faire assez de mauvais sang quand elle était pour\r
+les autres. Je n'en veux pas pour moi. La bonté qui consiste à donner\r
+raison à la fille publique contre le bourgeois, à l'agent de police\r
+contre le maire, à celui qui est en bas contre celui qui est en haut,\r
+c'est ce que j'appelle de la mauvaise bonté. C'est avec cette bonté-là\r
+que la société se désorganise. Mon Dieu! c'est bien facile d'être bon,\r
+le malaisé c'est d'être juste. Allez! si vous aviez été ce que je\r
+croyais, je n'aurais pas été bon pour vous, moi! vous auriez vu!\r
+Monsieur le maire, je dois me traiter comme je traiterais tout autre.\r
+Quand je réprimais des malfaiteurs, quand je sévissais sur des gredins,\r
+je me suis souvent dit à moi-même: toi, si tu bronches, si jamais je te\r
+prends en faute, sois tranquille!--J'ai bronché, je me prends en faute,\r
+tant pis! Allons, renvoyé, cassé, chassé! c'est bon. J'ai des bras, je\r
+travaillerai à la terre, cela m'est égal. Monsieur le maire, le bien du\r
+service veut un exemple. Je demande simplement la destitution de\r
+l'inspecteur Javert.\r
+\r
+Tout cela était prononcé d'un accent humble, fier, désespéré et\r
+convaincu qui donnait je ne sais quelle grandeur bizarre à cet étrange\r
+honnête homme.\r
+\r
+--Nous verrons, fit M. Madeleine.\r
+\r
+Et il lui tendit la main.\r
+\r
+Javert recula, et dit d'un ton farouche:\r
+\r
+--Pardon, monsieur le maire, mais cela ne doit pas être. Un maire ne\r
+donne pas la main à un mouchard.\r
+\r
+Il ajouta entre ses dents:\r
+\r
+--Mouchard, oui; du moment où j'ai médusé de la police, je ne suis plus\r
+qu'un mouchard. Puis il salua profondément, et se dirigea vers la porte.\r
+Là il se retourna, et, les yeux toujours baissés:\r
+\r
+--Monsieur le maire, dit-il, je continuerai le service jusqu'à ce que je\r
+sois remplacé.\r
+\r
+Il sortit. M. Madeleine resta rêveur, écoutant ce pas ferme et assuré\r
+qui s'éloignait sur le pavé du corridor.\r

+\r
+Chapitre I\r
+\r
+La soeur Simplice\r
+\r
+\r
+Les incidents qu'on va lire n'ont pas tous été connus à\r
+Montreuil-sur-mer, mais le peu qui en a percé a laissé dans cette ville\r
+un tel souvenir, que ce serait une grave lacune dans ce livre si nous ne\r
+les racontions dans leurs moindres détails.\r
+\r
+Dans ces détails, le lecteur rencontrera deux ou trois circonstances\r
+invraisemblables que nous maintenons par respect pour la vérité.\r
+\r
+Dans l'après-midi qui suivit la visite de Javert, M. Madeleine alla voir\r
+la Fantine comme d'habitude.\r
+\r
+Avant de pénétrer près de Fantine, il fit demander la soeur Simplice.\r
+Les deux religieuses qui faisaient le service de l'infirmerie, dames\r
+lazaristes comme toutes les soeurs de charité, s'appelaient soeur\r
+Perpétue et soeur Simplice.\r
+\r
+La soeur Perpétue était la première villageoise venue, grossièrement\r
+soeur de charité, entrée chez Dieu comme on entre en place. Elle était\r
+religieuse comme on est cuisinière. Ce type n'est point très rare. Les\r
+ordres monastiques acceptent volontiers cette lourde poterie paysanne,\r
+aisément façonnée en capucin ou en ursuline. Ces rusticités s'utilisent\r
+pour les grosses besognes de la dévotion. La transition d'un bouvier à\r
+un carme n'a rien de heurté; l'un devient l'autre sans grand travail; le\r
+fond commun d'ignorance du village et du cloître est une préparation\r
+toute faite, et met tout de suite le campagnard de plain-pied avec le\r
+moine. Un peu d'ampleur au sarrau, et voilà un froc. La soeur Perpétue\r
+était une forte religieuse, de Marines, près Pontoise, patoisant,\r
+psalmodiant, bougonnant, sucrant la tisane selon le bigotisme ou\r
+l'hypocrisie du grabataire, brusquant les malades, bourrue avec les\r
+mourants, leur jetant presque Dieu au visage, lapidant l'agonie avec des\r
+prières en colère, hardie, honnête et rougeaude.\r
+\r
+La soeur Simplice était blanche d'une blancheur de cire. Près de soeur\r
+Perpétue, c'était le cierge à côté de la chandelle. Vincent de Paul a\r
+divinement fixé la figure de la soeur de charité dans ces admirables\r
+paroles où il mêle tant de liberté à tant de servitude: «Elles n'auront\r
+pour monastère que la maison des malades, pour cellule qu'une chambre de\r
+louage, pour chapelle que l'église de leur paroisse, pour cloître que\r
+les rues de la ville ou les salles des hôpitaux, pour clôture que\r
+l'obéissance, pour grille que la crainte de Dieu, pour voile que la\r
+modestie.» Cet idéal était vivant dans la soeur Simplice. Personne n'eût\r
+pu dire l'âge de la soeur Simplice; elle n'avait jamais été jeune et\r
+semblait ne devoir jamais être vieille. C'était une personne--nous\r
+n'osons dire une femme--calme, austère, de bonne compagnie, froide, et\r
+qui n'avait jamais menti. Elle était si douce qu'elle paraissait\r
+fragile; plus solide d'ailleurs que le granit. Elle touchait aux\r
+malheureux avec de charmants doigts fins et purs. Il y avait, pour ainsi\r
+dire, du silence dans sa parole; elle parlait juste le nécessaire, et\r
+elle avait un son de voix qui eût tout à la fois édifié un confessionnal\r
+et enchanté un salon. Cette délicatesse s'accommodait de la robe de\r
+bure, trouvant à ce rude contact un rappel continuel du ciel et de Dieu.\r
+Insistons sur un détail. N'avoir jamais menti, n'avoir jamais dit, pour\r
+un intérêt quelconque, même indifféremment, une chose qui ne fût la\r
+vérité, la sainte vérité, c'était le trait distinctif de la soeur\r
+Simplice; c'était l'accent de sa vertu. Elle était presque célèbre dans\r
+la congrégation pour cette véracité imperturbable. L'abbé Sicard parle\r
+de la soeur Simplice dans une lettre au sourd-muet Massieu. Si sincères,\r
+si loyaux et si purs que nous soyons, nous avons tous sur notre candeur\r
+au moins la fêlure du petit mensonge innocent. Elle, point. Petit\r
+mensonge, mensonge innocent, est-ce que cela existe? Mentir, c'est\r
+l'absolu du mal. Peu mentir n'est pas possible; celui qui ment, ment\r
+tout le mensonge; mentir, c'est la face même du démon; Satan a deux\r
+noms, il s'appelle Satan et il s'appelle Mensonge. Voilà ce qu'elle\r
+pensait. Et comme elle pensait, elle pratiquait. Il en résultait cette\r
+blancheur dont nous avons parlé, blancheur qui couvrait de son\r
+rayonnement même ses lèvres et ses yeux. Son sourire était blanc, son\r
+regard était blanc. Il n'y avait pas une toile d'araignée, pas un grain\r
+de poussière à la vitre de cette conscience. En entrant dans l'obédience\r
+de saint Vincent de Paul, elle avait pris le nom de Simplice par choix\r
+spécial. Simplice de Sicile, on le sait, est cette sainte qui aima mieux\r
+se laisser arracher les deux seins que de répondre, étant née à\r
+Syracuse, qu'elle était née à Ségeste, mensonge qui la sauvait. Cette\r
+patronne convenait à cette âme.\r
+\r
+La soeur Simplice, en entrant dans l'ordre, avait deux défauts dont elle\r
+s'était peu à peu corrigée; elle avait eu le goût des friandises et elle\r
+avait aimé à recevoir des lettres. Elle ne lisait jamais qu'un livre de\r
+prières en gros caractères et en latin. Elle ne comprenait pas le latin,\r
+mais elle comprenait le livre.\r
+\r
+La pieuse fille avait pris en affection Fantine, y sentant probablement\r
+de la vertu latente, et s'était dévouée à la soigner presque\r
+exclusivement.\r
+\r
+M. Madeleine emmena à part la soeur Simplice et lui recommanda Fantine\r
+avec un accent singulier dont la soeur se souvint plus tard.\r
+\r
+En quittant la soeur, il s'approcha de Fantine.\r
+\r
+Fantine attendait chaque jour l'apparition de M. Madeleine comme on\r
+attend un rayon de chaleur et de joie. Elle disait aux soeurs:\r
+\r
+--Je ne vis que lorsque monsieur le maire est là.\r
+\r
+Elle avait ce jour-là beaucoup de fièvre. Dès qu'elle vit M. Madeleine,\r
+elle lui demanda:\r
+\r
+--Et Cosette?\r
+\r
+Il répondit en souriant:\r
+\r
+--Bientôt.\r
+\r
+M. Madeleine fut avec Fantine comme à l'ordinaire. Seulement il resta\r
+une heure au lieu d'une demi-heure, au grand contentement de Fantine. Il\r
+fît mille instances à tout le monde pour que rien ne manquât à la\r
+malade. On remarqua qu'il y eut un moment où son visage devint très\r
+sombre. Mais cela s'expliqua quand on sut que le médecin s'était penché\r
+à son oreille et lui avait dit:\r
+\r
+--Elle baisse beaucoup.\r
+\r
+Puis il rentra à la mairie, et le garçon de bureau le vit examiner avec\r
+attention une carte routière de France qui était suspendue dans son\r
+cabinet. Il écrivit quelques chiffres au crayon sur un papier.\r

+\r
+Chapitre II\r
+\r
+Perspicacité de maître Scaufflaire\r
+\r
+\r
+De la mairie il se rendit au bout de la ville chez un Flamand, maître\r
+Scaufflaër, francisé Scaufflaire, qui louait des chevaux et des\r
+«cabriolets à volonté».\r
+\r
+Pour aller chez ce Scaufflaire, le plus court était de prendre une rue\r
+peu fréquentée où était le presbytère de la paroisse que M. Madeleine\r
+habitait. Le curé était, disait-on, un homme digne et respectable, et de\r
+bon conseil. À l'instant où M. Madeleine arriva devant le presbytère, il\r
+n'y avait dans la rue qu'un passant, et ce passant remarqua ceci: M. le\r
+maire, après avoir dépassé la maison curiale, s'arrêta, demeura\r
+immobile, puis revint sur ses pas et rebroussa chemin jusqu'à la porte\r
+du presbytère, qui était une porte bâtarde avec marteau de fer. Il mit\r
+vivement la main au marteau, et le souleva; puis il s'arrêta de nouveau,\r
+et resta court, et comme pensif, et, après quelques secondes, au lieu de\r
+laisser bruyamment retomber le marteau, il le reposa doucement et reprit\r
+son chemin avec une sorte de hâte qu'il n'avait pas auparavant.\r
+\r
+M. Madeleine trouva maître Scaufflaire chez lui occupé à repiquer un\r
+harnais.\r
+\r
+--Maître Scaufflaire, demanda-t-il, avez-vous un bon cheval?\r
+\r
+--Monsieur le maire, dit le Flamand, tous mes chevaux sont bons.\r
+Qu'entendez-vous par un bon cheval?\r
+\r
+--J'entends un cheval qui puisse faire vingt lieues en un jour.\r
+\r
+--Diable! fit le Flamand, vingt lieues!\r
+\r
+--Oui.\r
+\r
+--Attelé à un cabriolet?\r
+\r
+--Oui.\r
+\r
+--Et combien de temps se reposera-t-il après la course?\r
+\r
+--Il faut qu'il puisse au besoin repartir le lendemain.\r
+\r
+--Pour refaire le même trajet?\r
+\r
+--Oui.\r
+\r
+--Diable! diable! et c'est vingt lieues? M. Madeleine tira de sa poche\r
+le papier où il avait crayonné des chiffres. Il les montra au Flamand.\r
+C'étaient les chiffres 5, 6, 8-1/2.\r
+\r
+--Vous voyez, dit-il. Total, dix-neuf et demi, autant dire vingt lieues.\r
+\r
+--Monsieur le maire, reprit le Flamand, j'ai votre affaire. Mon petit\r
+cheval blanc. Vous avez dû le voir passer quelquefois. C'est une petite\r
+bête du bas Boulonnais. C'est plein de feu. On a voulu d'abord en faire\r
+un cheval de selle. Bah! il ruait, il flanquait tout le monde par terre.\r
+On le croyait vicieux, on ne savait qu'en faire. Je l'ai acheté. Je l'ai\r
+mis au cabriolet. Monsieur, c'est cela qu'il voulait; il est doux comme\r
+une fille, il va le vent. Ah! par exemple, il ne faudrait pas lui monter\r
+sur le dos. Ce n'est pas son idée d'être cheval de selle. Chacun a son\r
+ambition. Tirer, oui, porter, non; il faut croire qu'il s'est dit ça.\r
+\r
+--Et il fera la course?\r
+\r
+--Vos vingt lieues. Toujours au grand trot, et en moins de huit heures.\r
+Mais voici à quelles conditions.\r
+\r
+--Dites.\r
+\r
+--Premièrement, vous le ferez souffler une heure à moitié chemin; il\r
+mangera, et on sera là pendant qu'il mangera pour empêcher le garçon de\r
+l'auberge de lui voler son avoine; car j'ai remarqué que dans les\r
+auberges l'avoine est plus souvent bue par les garçons d'écurie que\r
+mangée par les chevaux.\r
+\r
+--On sera là.\r
+\r
+--Deuxièmement.... Est-ce pour monsieur le maire le cabriolet?\r
+\r
+--Oui.\r
+\r
+--Monsieur le maire sait conduire?\r
+\r
+--Oui.\r
+\r
+--Eh bien, monsieur le maire voyagera seul et sans bagage afin de ne\r
+point charger le cheval.\r
+\r
+--Convenu.\r
+\r
+--Mais monsieur le maire, n'ayant personne avec lui, sera obligé de\r
+prendre la peine de surveiller lui-même l'avoine.\r
+\r
+--C'est dit.\r
+\r
+--Il me faudra trente francs par jour. Les jours de repos payés. Pas un\r
+liard de moins, et la nourriture de la bête à la charge de monsieur le\r
+maire.\r
+\r
+M. Madeleine tira trois napoléons de sa bourse et les mit sur la table.\r
+\r
+--Voilà deux jours d'avance.\r
+\r
+--Quatrièmement, pour une course pareille sur cabriolet serait trop\r
+lourd et fatiguerait le cheval. Il faudrait que monsieur le maire\r
+consentît à voyager dans un petit tilbury que j'ai.\r
+\r
+--J'y consens.\r
+\r
+--C'est léger, mais c'est découvert.\r
+\r
+--Cela m'est égal.\r
+\r
+--Monsieur le maire a-t-il réfléchi que nous sommes en hiver?...\r
+\r
+M. Madeleine ne répondit pas. Le Flamand reprit:\r
+\r
+--Qu'il fait très froid?\r
+\r
+M. Madeleine garda le silence. Maître Scaufflaire continua:\r
+\r
+--Qu'il peut pleuvoir?\r
+\r
+M. Madeleine leva la tête et dit:\r
+\r
+--Le tilbury et le cheval seront devant ma porte demain à quatre heures\r
+et demie du matin.\r
+\r
+--C'est entendu, monsieur le maire, répondit Scaufflaire, puis, grattant\r
+avec l'ongle de son pouce une tache qui était dans le bois de la table,\r
+il reprit de cet air insouciant que les Flamands savent si bien mêler à\r
+leur finesse:\r
+\r
+--Mais voilà que j'y songe à présent! monsieur le maire ne me dit pas où\r
+il va. Où est-ce que va monsieur le maire?\r
+\r
+Il ne songeait pas à autre chose depuis le commencement de la\r
+conversation, mais il ne savait pourquoi il n'avait pas osé faire cette\r
+question.\r
+\r
+--Votre cheval a-t-il de bonnes jambes de devant? dit M. Madeleine.\r
+\r
+--Oui, monsieur le maire. Vous le soutiendrez un peu dans les descentes.\r
+Y a-t-il beaucoup de descentes d'ici où vous allez?\r
+\r
+--N'oubliez pas d'être à ma porte à quatre heures et demie du matin,\r
+très précises, répondit M. Madeleine; et il sortit.\r
+\r
+Le Flamand resta «tout bête», comme il disait lui-même quelque temps\r
+après.\r
+\r
+Monsieur le maire était sorti depuis deux ou trois minutes, lorsque la\r
+porte se rouvrit; c'était M. le maire. Il avait toujours le même air\r
+impassible et préoccupé.\r
+\r
+--Monsieur Scaufflaire, dit-il, à quelle somme estimez-vous le cheval et\r
+le tilbury que vous me louerez, l'un portant l'autre?\r
+\r
+--L'un traînant l'autre, monsieur le maire, dit le Flamand avec un gros\r
+rire.\r
+\r
+--Soit. Eh bien!\r
+\r
+--Est-ce que monsieur le maire veut me les acheter?\r
+\r
+--Non, mais à tout événement, je veux vous les garantir. À mon retour\r
+vous me rendrez la somme. Combien estimez-vous cabriolet et cheval?\r
+\r
+--À cinq cents francs, monsieur le maire.\r
+\r
+--Les voici.\r
+\r
+M. Madeleine posa un billet de banque sur la table, puis sortit et cette\r
+fois ne rentra plus.\r
+\r
+Maître Scaufflaire regretta affreusement de n'avoir point dit mille\r
+francs. Du reste le cheval et le tilbury, en bloc, valaient cent écus.\r
+\r
+Le Flamand appela sa femme, et lui conta la chose. Où diable monsieur le\r
+maire peut-il aller? Ils tinrent conseil.\r
+\r
+--Il va à Paris, dit la femme.\r
+\r
+--Je ne crois pas, dit le mari.\r
+\r
+M. Madeleine avait oublié sur la cheminée le papier où il avait tracé\r
+des chiffres. Le Flamand le prit et l'étudia.\r
+\r
+--Cinq, six, huit et demi? cela doit marquer des relais de poste.\r
+\r
+Il se tourna vers sa femme.\r
+\r
+--J'ai trouvé.\r
+\r
+--Comment?\r
+\r
+--Il y a cinq lieues d'ici à Hesdin, six de Hesdin à Saint-Pol, huit et\r
+demie de Saint-Pol à Arras. Il va à Arras.\r
+\r
+Cependant M. Madeleine était rentré chez lui.\r
+\r
+Pour revenir de chez maître Scaufflaire, il avait pris le plus long,\r
+comme si la porte du presbytère avait été pour lui une tentation, et\r
+qu'il eût voulu l'éviter. Il était monté dans sa chambre et s'y était\r
+enfermé, ce qui n'avait rien que de simple, car il se couchait\r
+volontiers de bonne heure. Pourtant la concierge de la fabrique, qui\r
+était en même temps l'unique servante de M. Madeleine, observa que sa\r
+lumière s'éteignit à huit heures et demie, et elle le dit au caissier\r
+qui rentrait, en ajoutant:\r
+\r
+--Est-ce que monsieur le maire est malade? je lui ai trouvé l'air un peu\r
+singulier.\r
+\r
+Ce caissier habitait une chambre située précisément au-dessous de la\r
+chambre de M. Madeleine. Il ne prit point garde aux paroles de la\r
+portière, se coucha et s'endormit. Vers minuit, il se réveilla\r
+brusquement; il avait entendu à travers son sommeil un bruit au-dessus\r
+de sa tête. Il écouta. C'était un pas qui allait et venait, comme si\r
+l'on marchait dans la chambre en haut. Il écouta plus attentivement, et\r
+reconnut le pas de M. Madeleine. Cela lui parut étrange; habituellement\r
+aucun bruit ne se faisait dans la chambre de M. Madeleine avant l'heure\r
+de son lever. Un moment après le caissier entendit quelque chose qui\r
+ressemblait à une armoire qu'on ouvre et qu'on referme. Puis on dérangea\r
+un meuble, il y eut un silence, et le pas recommença. Le caissier se\r
+dressa sur son séant, s'éveilla tout à fait, regarda, et à travers les\r
+vitres de sa croisée aperçut sur le mur d'en face la réverbération\r
+rougeâtre d'une fenêtre éclairée. À la direction des rayons, ce ne\r
+pouvait être que la fenêtre de la chambre de M. Madeleine. La\r
+réverbération tremblait comme si elle venait plutôt d'un feu allumé que\r
+d'une lumière. L'ombre des châssis vitrés ne s'y dessinait pas, ce qui\r
+indiquait que la fenêtre était toute grande ouverte. Par le froid qu'il\r
+faisait, cette fenêtre ouverte était surprenante. Le caissier se\r
+rendormit. Une heure ou deux après, il se réveilla encore. Le même pas,\r
+lent et régulier, allait et venait toujours au-dessus de sa tête.\r
+\r
+La réverbération se dessinait toujours sur le mur, mais elle était\r
+maintenant pâle et paisible comme le reflet d'une lampe ou d'une bougie.\r
+La fenêtre était toujours ouverte. Voici ce qui se passait dans la\r
+chambre de M. Madeleine.\r
+\r
+\r
+\r
+\r
+Chapitre III\r
+\r
+Une tempête sous un crâne\r
+\r
+\r
+Le lecteur a sans doute deviné que M. Madeleine n'est autre que Jean\r
+Valjean.\r
+\r
+Nous avons déjà regardé dans les profondeurs de cette conscience; le\r
+moment est venu d'y regarder encore. Nous ne le faisons pas sans émotion\r
+et sans tremblement. Il n'existe rien de plus terrifiant que cette sorte\r
+de contemplation. L'oeil de l'esprit ne peut trouver nulle part plus\r
+d'éblouissements ni plus de ténèbres que dans l'homme; il ne peut se\r
+fixer sur aucune chose qui soit plus redoutable, plus compliquée, plus\r
+mystérieuse et plus infinie. Il y a un spectacle plus grand que la mer,\r
+c'est le ciel; il y a un spectacle plus grand que le ciel, c'est\r
+l'intérieur de l'âme.\r
+\r
+Faire le poème de la conscience humaine, ne fût-ce qu'à propos d'un seul\r
+homme, ne fût-ce qu'à propos du plus infime des hommes, ce serait fondre\r
+toutes les épopées dans une épopée supérieure et définitive. La\r
+conscience, c'est le chaos des chimères, des convoitises et des\r
+tentatives, la fournaise des rêves, l'antre des idées dont on a honte;\r
+c'est le pandémonium des sophismes, c'est le champ de bataille des\r
+passions. À de certaines heures, pénétrez à travers la face livide d'un\r
+être humain qui réfléchit, et regardez derrière, regardez dans cette\r
+âme, regardez dans cette obscurité. Il y a là, sous le silence\r
+extérieur, des combats de géants comme dans Homère, des mêlées de\r
+dragons et d'hydres et des nuées de fantômes comme dans Milton, des\r
+spirales visionnaires comme chez Dante. Chose sombre que cet infini que\r
+tout homme porte en soi et auquel il mesure avec désespoir les volontés\r
+de son cerveau et les actions de sa vie!\r
+\r
+Alighieri rencontra un jour une sinistre porte devant laquelle il\r
+hésita. En voici une aussi devant nous, au seuil de laquelle nous\r
+hésitons. Entrons pourtant.\r
+\r
+Nous n'avons que peu de chose à ajouter à ce que le lecteur connaît déjà\r
+de ce qui était arrivé à Jean Valjean depuis l'aventure de\r
+Petit-Gervais. À partir de ce moment, on l'a vu, il fut un autre homme.\r
+Ce que l'évêque avait voulu faire de lui, il l'exécuta. Ce fut plus\r
+qu'une transformation, ce fut une transfiguration.\r
+\r
+Il réussit à disparaître, vendit l'argenterie de l'évêque, ne gardant\r
+que les flambeaux, comme souvenir, se glissa de ville en ville, traversa\r
+la France, vint à Montreuil-sur-mer, eut l'idée que nous avons dite,\r
+accomplit ce que nous avons raconté, parvint à se faire insaisissable et\r
+inaccessible, et désormais, établi à Montreuil-sur-mer, heureux de\r
+sentir sa conscience attristée par son passé et la première moitié de\r
+son existence démentie par la dernière, il vécut paisible, rassuré et\r
+espérant, n'ayant plus que deux pensées: cacher son nom, et sanctifier\r
+sa vie; échapper aux hommes, et revenir à Dieu.\r
+\r
+Ces deux pensées étaient si étroitement mêlées dans son esprit qu'elles\r
+n'en formaient qu'une seule; elles étaient toutes deux également\r
+absorbantes et impérieuses, et dominaient ses moindres actions.\r
+D'ordinaire elles étaient d'accord pour régler la conduite de sa vie;\r
+elles le tournaient vers l'ombre; elles le faisaient bienveillant et\r
+simple; elles lui conseillaient les mêmes choses. Quelquefois cependant\r
+il y avait conflit entre elles. Dans ce cas-là, on s'en souvient,\r
+l'homme que tout le pays de Montreuil-sur-mer appelait M. Madeleine ne\r
+balançait pas à sacrifier la première à la seconde, sa sécurité à sa\r
+vertu. Ainsi, en dépit de toute réserve et de toute prudence, il avait\r
+gardé les chandeliers de l'évêque, porté son deuil, appelé et interrogé\r
+tous les petits savoyards qui passaient, pris des renseignements sur les\r
+familles de Faverolles, et sauvé la vie au vieux Fauchelevent, malgré\r
+les inquiétantes insinuations de Javert. Il semblait, nous l'avons déjà\r
+remarqué, qu'il pensât, à l'exemple de tous ceux qui ont été sages,\r
+saints et justes, que son premier devoir n'était pas envers lui.\r
+\r
+Toutefois, il faut le dire, jamais rien de pareil ne s'était encore\r
+présenté. Jamais les deux idées qui gouvernaient le malheureux homme\r
+dont nous racontons les souffrances n'avaient engagé une lutte si\r
+sérieuse. Il le comprit confusément, mais profondément, dès les\r
+premières paroles que prononça Javert, en entrant dans son cabinet.\r
+\r
+Au moment où fut si étrangement articulé ce nom qu'il avait enseveli\r
+sous tant d'épaisseurs, il fut saisi de stupeur et comme enivré par la\r
+sinistre bizarrerie de sa destinée, et, à travers cette stupeur, il eut\r
+ce tressaillement qui précède les grandes secousses; il se courba comme\r
+un chêne à l'approche d'un orage, comme un soldat à l'approche d'un\r
+assaut. Il sentit venir sur sa tête des ombres pleines de foudres et\r
+d'éclairs. Tout en écoutant parler Javert, il eut une première pensée\r
+d'aller, de courir, de se dénoncer, de tirer ce Champmathieu de prison\r
+et de s'y mettre; cela fut douloureux et poignant comme une incision\r
+dans la chair vive, puis cela passa, et il se dit: «Voyons! voyons!» Il\r
+réprima ce premier mouvement généreux et recula devant l'héroïsme.\r
+\r
+Sans doute, il serait beau qu'après les saintes paroles de l'évêque,\r
+après tant d'années de repentir et d'abnégation, au milieu d'une\r
+pénitence admirablement commencée, cet homme, même en présence d'une si\r
+terrible conjoncture, n'eût pas bronché un instant et eût continué de\r
+marcher du même pas vers ce précipice ouvert au fond duquel était le\r
+ciel; cela serait beau, mais cela ne fut pas ainsi. Il faut bien que\r
+nous rendions compte des choses qui s'accomplissaient dans cette âme, et\r
+nous ne pouvons dire que ce qui y était. Ce qui l'emporta tout d'abord,\r
+ce fut l'instinct de la conservation; il rallia en hâte ses idées,\r
+étouffa ses émotions, considéra la présence de Javert, ce grand péril,\r
+ajourna toute résolution avec la fermeté de l'épouvante, s'étourdit sur\r
+ce qu'il y avait à faire, et reprit son calme comme un lutteur ramasse\r
+son bouclier.\r
+\r
+Le reste de la journée il fut dans cet état, un tourbillon au dedans,\r
+une tranquillité profonde au dehors; il ne prit que ce qu'on pourrait\r
+appeler «les mesures conservatoires». Tout était encore confus et se\r
+heurtait dans son cerveau; le trouble y était tel qu'il ne voyait\r
+distinctement la forme d'aucune idée; et lui-même n'aurait pu rien dire\r
+de lui-même, si ce n'est qu'il venait de recevoir un grand coup. Il se\r
+rendit comme d'habitude près du lit de douleur de Fantine et prolongea\r
+sa visite, par un instinct de bonté, se disant qu'il fallait agir ainsi\r
+et la bien recommander aux soeurs pour le cas où il arriverait qu'il eût\r
+à s'absenter. Il sentit vaguement qu'il faudrait peut-être aller à\r
+Arras, et, sans être le moins du monde décidé à ce voyage, il se dit\r
+qu'à l'abri de tout soupçon comme il l'était, il n'y avait point\r
+d'inconvénient à être témoin de ce qui se passerait, et il retint le\r
+tilbury de Scaufflaire, afin d'être préparé à tout événement.\r
+\r
+Il dîna avec assez d'appétit.\r
+\r
+Rentré dans sa chambre il se recueillit.\r
+\r
+Il examina la situation et la trouva inouïe; tellement inouïe qu'au\r
+milieu de sa rêverie, par je ne sais quelle impulsion d'anxiété presque\r
+inexplicable, il se leva de sa chaise et ferma sa porte au verrou. Il\r
+craignait qu'il n'entrât encore quelque chose. Il se barricadait contre\r
+le possible.\r
+\r
+Un moment après il souffla sa lumière. Elle le gênait.\r
+\r
+Il lui semblait qu'on pouvait le voir.\r
+\r
+Qui, on?\r
+\r
+Hélas! ce qu'il voulait mettre à la porte était entré ce qu'il voulait\r
+aveugler, le regardait. Sa conscience.\r
+\r
+Sa conscience, c'est-à-dire Dieu.\r
+\r
+Pourtant, dans le premier moment, il se fit illusion; il eut un\r
+sentiment de sûreté et de solitude; le verrou tiré, il se crut\r
+imprenable; la chandelle éteinte, il se sentit invisible. Alors il prit\r
+possession de lui-même; il posa ses coudes sur la table, appuya la tête\r
+sur sa main, et se mit à songer dans les ténèbres.\r
+\r
+--Où en suis-je?--Est-ce que je ne rêve pas? Que m'a-t-on dit?--Est-il\r
+bien vrai que j'aie vu ce Javert et qu'il m'ait parlé ainsi?--Que peut\r
+être ce Champmathieu?--Il me ressemble donc?--Est-ce possible?--Quand\r
+je pense qu'hier j'étais si tranquille et si loin de me douter de\r
+rien!--Qu'est-ce que je faisais donc hier à pareille heure?--Qu'y a-t-il\r
+dans cet incident?--Comment se dénouera-t-il?--Que faire?\r
+\r
+Voilà dans quelle tourmente il était. Son cerveau avait perdu la force\r
+de retenir ses idées, elles passaient comme des ondes, et il prenait son\r
+front dans ses deux mains pour les arrêter.\r
+\r
+De ce tumulte qui bouleversait sa volonté et sa raison, et dont il\r
+cherchait à tirer une évidence et une résolution, rien ne se dégageait\r
+que l'angoisse.\r
+\r
+Sa tête était brûlante. Il alla à la fenêtre et l'ouvrit toute grande.\r
+Il n'y avait pas d'étoiles au ciel. Il revint s'asseoir près de la\r
+table.\r
+\r
+La première heure s'écoula ainsi.\r
+\r
+Peu à peu cependant des linéaments vagues commencèrent à se former et à\r
+se fixer dans sa méditation, et il put entrevoir avec la précision de la\r
+réalité, non l'ensemble de la situation, mais quelques détails.\r
+\r
+Il commença par reconnaître que, si extraordinaire et si critique que\r
+fût cette situation, il en était tout à fait le maître.\r
+\r
+Sa stupeur ne fit que s'en accroître.\r
+\r
+Indépendamment du but sévère et religieux que se proposaient ses\r
+actions, tout ce qu'il avait fait jusqu'à ce jour n'était autre chose\r
+qu'un trou qu'il creusait pour y enfouir son nom. Ce qu'il avait\r
+toujours le plus redouté, dans ses heures de repli sur lui-même, dans\r
+ses nuits d'insomnie, c'était d'entendre jamais prononcer ce nom; il se\r
+disait que ce serait là pour lui la fin de tout; que le jour où ce nom\r
+reparaîtrait, il ferait évanouir autour de lui sa vie nouvelle, et qui\r
+sait même peut-être? au dedans de lui sa nouvelle âme. Il frémissait de\r
+la seule pensée que c'était possible. Certes, si quelqu'un lui eût dit\r
+en ces moments-là qu'une heure viendrait où ce nom retentirait à son\r
+oreille, où ce hideux mot, Jean Valjean, sortirait tout à coup de la\r
+nuit et se dresserait devant lui, où cette lumière formidable faite pour\r
+dissiper le mystère dont il s'enveloppait resplendirait subitement sur\r
+sa tête; et que ce nom ne le menacerait pas, que cette lumière ne\r
+produirait qu'une obscurité plus épaisse, que ce voile déchiré\r
+accroîtrait le mystère; que ce tremblement de terre consoliderait son\r
+édifice, que ce prodigieux incident n'aurait d'autre résultat, si bon\r
+lui semblait, à lui, que de rendre son existence à la fois plus claire\r
+et plus impénétrable, et que, de sa confrontation avec le fantôme de\r
+Jean Valjean, le bon et digne bourgeois monsieur Madeleine sortirait\r
+plus honoré, plus paisible et plus respecté que jamais,--si quelqu'un\r
+lui eût dit cela, il eût hoché la tête et regardé ces paroles comme\r
+insensées. Eh bien! tout cela venait précisément d'arriver, tout cet\r
+entassement de l'impossible était un fait, et Dieu avait permis que ces\r
+choses folles devinssent des choses réelles!\r
+\r
+Sa rêverie continuait de s'éclaircir. Il se rendait de plus en plus\r
+compte de sa position. Il lui semblait qu'il venait de s'éveiller de je\r
+ne sais quel sommeil, et qu'il se trouvait glissant sur une pente au\r
+milieu de la nuit, debout, frissonnant, reculant en vain, sur le bord\r
+extrême d'un abîme. Il entrevoyait distinctement dans l'ombre un\r
+inconnu, un étranger, que la destinée prenait pour lui et poussait dans\r
+le gouffre à sa place. Il fallait, pour que le gouffre se refermât, que\r
+quelqu'un y tombât, lui ou l'autre.\r
+\r
+Il n'avait qu'à laisser faire.\r
+\r
+La clarté devint complète, et il s'avoua ceci:--Que sa place était vide\r
+aux galères, qu'il avait beau faire, qu'elle l'y attendait toujours, que\r
+le vol de Petit-Gervais l'y ramenait, que cette place vide l'attendrait\r
+et l'attirerait jusqu'à ce qu'il y fût, que cela était inévitable et\r
+fatal.--Et puis il se dit:--Qu'en ce moment il avait un remplaçant,\r
+qu'il paraissait qu'un nommé Champmathieu avait cette mauvaise chance,\r
+et que, quant à lui, présent désormais au bagne dans la personne de ce\r
+Champmathieu, présent dans la société sous le nom de M. Madeleine, il\r
+n'avait plus rien à redouter, pourvu qu'il n'empêchât pas les hommes de\r
+sceller sur la tête de ce Champmathieu cette pierre de l'infamie qui,\r
+comme la pierre du sépulcre, tombe une fois et ne se relève jamais.\r
+\r
+Tout cela était si violent et si étrange qu'il se fit soudain en lui\r
+cette espèce de mouvement indescriptible qu'aucun homme n'éprouve plus\r
+de deux ou trois fois dans sa vie, sorte de convulsion de la conscience\r
+qui remue tout ce que le coeur a de douteux, qui se compose d'ironie, de\r
+joie et de désespoir, et qu'on pourrait appeler un éclat de rire\r
+intérieur.\r
+\r
+Il ralluma brusquement sa bougie.\r
+\r
+--Eh bien quoi! se dit-il, de quoi est-ce que j'ai peur? qu'est-ce que\r
+j'ai à songer comme cela? Me voilà sauvé. Tout est fini. Je n'avais plus\r
+qu'une porte entr'ouverte par laquelle mon passé pouvait faire irruption\r
+dans ma vie; cette porte, la voilà murée! à jamais! Ce Javert qui me\r
+trouble depuis si longtemps, ce redoutable instinct qui semblait m'avoir\r
+deviné, qui m'avait deviné, pardieu! et qui me suivait partout, cet\r
+affreux chien de chasse toujours en arrêt sur moi, le voilà dérouté,\r
+occupé ailleurs, absolument dépisté! Il est satisfait désormais, il me\r
+laissera tranquille, il tient son Jean Valjean! Qui sait même, il est\r
+probable qu'il voudra quitter la ville! Et tout cela s'est fait sans\r
+moi! Et je n'y suis pour rien! Ah çà, mais! qu'est-ce qu'il y a de\r
+malheureux dans ceci? Des gens qui me verraient, parole d'honneur!\r
+croiraient qu'il m'est arrivé une catastrophe! Après tout, s'il y a du\r
+mal pour quelqu'un, ce n'est aucunement de ma faute. C'est la providence\r
+qui a tout fait. C'est qu'elle veut cela apparemment!\r
+\r
+Ai-je le droit de déranger ce qu'elle arrange? Qu'est-ce que je demande\r
+à présent? De quoi est-ce que je vais me mêler? Cela ne me regarde pas.\r
+Comment! je ne suis pas content! Mais qu'est-ce qu'il me faut donc? Le\r
+but auquel j'aspire depuis tant d'années, le songe de mes nuits, l'objet\r
+de mes prières au ciel, la sécurité, je l'atteins! C'est Dieu qui le\r
+veut. Je n'ai rien à faire contre la volonté de Dieu. Et pourquoi Dieu\r
+le veut-il? Pour que je continue ce que j'ai commencé, pour que je fasse\r
+le bien, pour que je sois un jour un grand et encourageant exemple, pour\r
+qu'il soit dit qu'il y a eu enfin un peu de bonheur attaché à cette\r
+pénitence que j'ai subie et à cette vertu où je suis revenu! Vraiment je\r
+ne comprends pas pourquoi j'ai eu peur tantôt d'entrer chez ce brave\r
+curé et de tout lui raconter comme à un confesseur, et de lui demander\r
+conseil, c'est évidemment là ce qu'il m'aurait dit. C'est décidé,\r
+laissons aller les choses! laissons faire le bon Dieu!\r
+\r
+Il se parlait ainsi dans les profondeurs de sa conscience, penché sur ce\r
+qu'on pourrait appeler son propre abîme. Il se leva de sa chaise, et se\r
+mit à marcher dans la chambre.--Allons, dit-il, n'y pensons plus. Voilà\r
+une résolution prise!--Mais il ne sentit aucune joie.\r
+\r
+Au contraire.\r
+\r
+On n'empêche pas plus la pensée de revenir à une idée que la mer de\r
+revenir à un rivage. Pour le matelot, cela s'appelle la marée; pour le\r
+coupable, cela s'appelle le remords. Dieu soulève l'âme comme l'océan.\r
+\r
+Au bout de peu d'instants, il eut beau faire, il reprit ce sombre\r
+dialogue dans lequel c'était lui qui parlait et lui qui écoutait, disant\r
+ce qu'il eût voulu taire, écoutant ce qu'il n'eût pas voulu entendre,\r
+cédant à cette puissance mystérieuse qui lui disait: pense! comme elle\r
+disait il y a deux mille ans à un autre condamné, marche!\r
+\r
+Avant d'aller plus loin et pour être pleinement compris, insistons sur\r
+une observation nécessaire.\r
+\r
+Il est certain qu'on se parle à soi-même, il n'est pas un être pensant\r
+qui ne l'ait éprouvé. On peut dire même que le verbe n'est jamais un\r
+plus magnifique mystère que lorsqu'il va, dans l'intérieur d'un homme,\r
+de la pensée à la conscience et qu'il retourne de la conscience à la\r
+pensée. C'est dans ce sens seulement qu'il faut entendre les mots\r
+souvent employés dans ce chapitre, il dit, il s'écria. On se dit, on se\r
+parle, on s'écrie en soi-même, sans que le silence extérieur soit rompu.\r
+Il y a un grand tumulte; tout parle en nous, excepté la bouche. Les\r
+réalités de l'âme, pour n'être point visibles et palpables, n'en sont\r
+pas moins des réalités.\r
+\r
+Il se demanda donc où il en était. Il s'interrogea sur cette «résolution\r
+prise». Il se confessa à lui-même que tout ce qu'il venait d'arranger\r
+dans son esprit était monstrueux, que «laisser aller les choses, laisser\r
+faire le bon Dieu», c'était tout simplement horrible. Laisser\r
+s'accomplir cette méprise de la destinée et des hommes, ne pas\r
+l'empêcher, s'y prêter par son silence, ne rien faire enfin, c'était\r
+faire tout! c'était le dernier degré de l'indignité hypocrite! c'était\r
+un crime bas, lâche, sournois, abject, hideux!\r
+\r
+Pour la première fois depuis huit années, le malheureux homme venait de\r
+sentir la saveur amère d'une mauvaise pensée et d'une mauvaise action.\r
+\r
+Il la recracha avec dégoût.\r
+\r
+Il continua de se questionner. Il se demanda sévèrement ce qu'il avait\r
+entendu par ceci: "Mon but est atteint!" Il se déclara que sa vie avait\r
+un but en effet. Mais quel but? cacher son nom? tromper la police?\r
+Était-ce pour une chose si petite qu'il avait fait tout ce qu'il avait\r
+fait? Est-ce qu'il n'avait pas un autre but, qui était le grand, qui\r
+était le vrai? Sauver, non sa personne, mais son âme. Redevenir honnête\r
+et bon. Être un juste! est-ce que ce n'était pas là surtout, là\r
+uniquement, ce qu'il avait toujours voulu, ce que l'évêque lui avait\r
+ordonné?--Fermer la porte à son passé? Mais il ne la fermait pas, grand\r
+Dieu! il la rouvrait en faisant une action infâme! mais il redevenait un\r
+voleur, et le plus odieux des voleurs! il volait à un autre son\r
+existence, sa vie, sa paix, sa place au soleil! il devenait un assassin!\r
+il tuait, il tuait moralement un misérable homme, il lui infligeait\r
+cette affreuse mort vivante, cette mort à ciel ouvert, qu'on appelle le\r
+bagne! Au contraire, se livrer, sauver cet homme frappé d'une si lugubre\r
+erreur, reprendre son nom, redevenir par devoir le forçat Jean Valjean,\r
+c'était là vraiment achever sa résurrection, et fermer à jamais l'enfer\r
+d'où il sortait! Y retomber en apparence, c'était en sortir en réalité!\r
+Il fallait faire cela! il n'avait rien fait s'il ne faisait pas cela!\r
+toute sa vie était inutile, toute sa pénitence était perdue, et il n'y\r
+avait plus qu'à dire: à quoi bon? Il sentait que l'évêque était là, que\r
+l'évêque était d'autant plus présent qu'il était mort, que l'évêque le\r
+regardait fixement, que désormais le maire Madeleine avec toutes ses\r
+vertus lui serait abominable, et que le galérien Jean Valjean serait\r
+admirable et pur devant lui. Que les hommes voyaient son masque, mais\r
+que l'évêque voyait sa face. Que les hommes voyaient sa vie, mais que\r
+l'évêque voyait sa conscience. Il fallait donc aller à Arras, délivrer\r
+le faux Jean Valjean, dénoncer le véritable! Hélas! c'était là le plus\r
+grand des sacrifices, la plus poignante des victoires, le dernier pas à\r
+franchir; mais il le fallait. Douloureuse destinée! il n'entrerait dans\r
+la sainteté aux yeux de Dieu que s'il rentrait dans l'infamie aux yeux\r
+des hommes!\r
+\r
+--Eh bien, dit-il, prenons ce parti! faisons notre devoir! sauvons cet\r
+homme!\r
+\r
+Il prononça ces paroles à haute voix, sans s'apercevoir qu'il parlait\r
+tout haut.\r
+\r
+Il prit ses livres, les vérifia et les mit en ordre. Il jeta au feu une\r
+liasse de créances qu'il avait sur de petits commerçants gênés. Il\r
+écrivit une lettre qu'il cacheta et sur l'enveloppe de laquelle on\r
+aurait pu lire, s'il y avait eu quelqu'un dans sa chambre en cet\r
+instant: _À Monsieur Laffitte, banquier, rue d'Artois, à Paris_.\r
+\r
+Il tira d'un secrétaire un portefeuille qui contenait quelques billets\r
+de banque et le passeport dont il s'était servi cette même année pour\r
+aller aux élections.\r
+\r
+Qui l'eût vu pendant qu'il accomplissait ces divers actes auxquels se\r
+mêlait une méditation si grave, ne se fût pas douté de ce qui se passait\r
+en lui. Seulement par moments ses lèvres remuaient; dans d'autres\r
+instants il relevait la tête et fixait son regard sur un point\r
+quelconque de la muraille, comme s'il y avait précisément là quelque\r
+chose qu'il voulait éclaircir ou interroger.\r
+\r
+La lettre à M. Laffitte terminée, il la mit dans sa poche ainsi que le\r
+portefeuille, et recommença à marcher.\r
+\r
+Sa rêverie n'avait point dévié. Il continuait de voir clairement son\r
+devoir écrit en lettres lumineuses qui flamboyaient devant ses yeux et\r
+se déplaçaient avec son regard:--_Va! nomme-toi! dénonce-toi!_\r
+\r
+Il voyait de même, et comme si elles se fussent mues devant lui avec des\r
+formes sensibles, les deux idées qui avaient été jusque-là la double\r
+règle de sa vie: cacher son nom, sanctifier son âme. Pour la première\r
+fois, elles lui apparaissaient absolument distinctes, et il voyait la\r
+différence qui les séparait. Il reconnaissait que l'une de ces idées\r
+était nécessairement bonne, tandis que l'autre pouvait devenir mauvaise;\r
+que celle-là était le dévouement et que celle-ci était la personnalité;\r
+que l'une disait: le _prochain_, et que l'autre disait: _moi_; que l'une\r
+venait de la lumière et que l'autre venait de la nuit.\r
+\r
+Elles se combattaient, il les voyait se combattre. À mesure qu'il\r
+songeait, elles avaient grandi devant l'oeil de son esprit; elles\r
+avaient maintenant des statures colossales; et il lui semblait qu'il\r
+voyait lutter au dedans de lui-même, dans cet infini dont nous parlions\r
+tout à l'heure, au milieu des obscurités et des lueurs, une déesse et\r
+une géante.\r
+\r
+Il était plein d'épouvante, mais il lui semblait que la bonne pensée\r
+l'emportait.\r
+\r
+Il sentait qu'il touchait à l'autre moment décisif de sa conscience et\r
+de sa destinée; que l'évêque avait marqué la première phase de sa vie\r
+nouvelle, et que ce Champmathieu en marquait la seconde. Après la grande\r
+crise, la grande épreuve.\r
+\r
+Cependant la fièvre, un instant apaisée, lui revenait peu à peu. Mille\r
+pensées le traversaient, mais elles continuaient de le fortifier dans sa\r
+résolution.\r
+\r
+Un moment il s'était dit:--qu'il prenait peut-être la chose trop\r
+vivement, qu'après tout ce Champmathieu n'était pas intéressant, qu'en\r
+somme il avait volé.\r
+\r
+Il se répondit:--Si cet homme a en effet volé quelques pommes, c'est un\r
+mois de prison. Il y a loin de là aux galères. Et qui sait même? a-t-il\r
+volé? est-ce prouvé? Le nom de Jean Valjean l'accable et semble\r
+dispenser de preuves. Les procureurs du roi n'agissent-ils pas\r
+habituellement ainsi? On le croit voleur, parce qu'on le sait forçat.\r
+\r
+Dans un autre instant, cette idée lui vint que, lorsqu'il se serait\r
+dénoncé, peut-être on considérerait l'héroïsme de son action, et sa vie\r
+honnête depuis sept ans, et ce qu'il avait fait pour le pays, et qu'on\r
+lui ferait grâce.\r
+\r
+Mais cette supposition s'évanouit bien vite, et il sourit amèrement en\r
+songeant que le vol des quarante sous à Petit-Gervais le faisait\r
+récidiviste, que cette affaire reparaîtrait certainement et, aux termes\r
+précis de la loi, le ferait passible des travaux forcés à perpétuité.\r
+\r
+Il se détourna de toute illusion, se détacha de plus en plus de la terre\r
+et chercha la consolation et la force ailleurs. Il se dit qu'il fallait\r
+faire son devoir; que peut-être même ne serait-il pas plus malheureux\r
+après avoir fait son devoir qu'après l'avoir éludé; que s'il _laissait\r
+faire_, s'il restait à Montreuil-sur-mer, sa considération, sa bonne\r
+renommée, ses bonnes oeuvres, la déférence, la vénération, sa charité,\r
+sa richesse, sa popularité, sa vertu, seraient assaisonnées d'un crime;\r
+et quel goût auraient toutes ces choses saintes liées à cette chose\r
+hideuse! tandis que, s'il accomplissait son sacrifice, au bagne, au\r
+poteau, au carcan, au bonnet vert, au travail sans relâche, à la honte\r
+sans pitié, il se mêlerait une idée céleste!\r
+\r
+Enfin il se dit qu'il y avait nécessité, que sa destinée était ainsi\r
+faite, qu'il n'était pas maître de déranger les arrangements d'en haut,\r
+que dans tous les cas il fallait choisir: ou la vertu au dehors et\r
+l'abomination au dedans, ou la sainteté au dedans et l'infamie au\r
+dehors.\r
+\r
+À remuer tant d'idées lugubres, son courage ne défaillait pas, mais son\r
+cerveau se fatiguait. Il commençait à penser malgré lui à d'autres\r
+choses, à des choses indifférentes. Ses artères battaient violemment\r
+dans ses tempes. Il allait et venait toujours. Minuit sonna d'abord à la\r
+paroisse, puis à la maison de ville. Il compta les douze coups aux deux\r
+horloges, et il compara le son des deux cloches. Il se rappela à cette\r
+occasion que quelques jours auparavant il avait vu chez un marchand de\r
+ferrailles une vieille cloche à vendre sur laquelle ce nom était écrit:\r
+_Antoine Albin de Romainville_.\r
+\r
+Il avait froid. Il alluma un peu de feu. Il ne songea pas à fermer la\r
+fenêtre.\r
+\r
+Cependant il était retombé dans sa stupeur. Il lui fallait faire un\r
+assez grand effort pour se rappeler à quoi il songeait avant que minuit\r
+sonnât. Il y parvint enfin.\r
+\r
+--Ah! oui, se dit-il, j'avais pris la résolution de me dénoncer.\r
+\r
+Et puis tout à coup il pensa à la Fantine.\r
+\r
+--Tiens! dit-il, et cette pauvre femme!\r
+\r
+Ici une crise nouvelle se déclara.\r
+\r
+Fantine, apparaissant brusquement dans sa rêverie, y fut comme un rayon\r
+d'une lumière inattendue. Il lui sembla que tout changeait d'aspect\r
+autour de lui, il s'écria:\r
+\r
+--Ah çà, mais! jusqu'ici je n'ai considéré que moi! je n'ai eu égard\r
+qu'à ma convenance! Il me convient de me taire ou de me\r
+dénoncer,--cacher ma personne ou sauver mon âme,--être un magistrat\r
+méprisable et respecté ou un galérien infâme et vénérable, c'est moi,\r
+c'est toujours moi, ce n'est que moi! Mais, mon Dieu, c'est de l'égoïsme\r
+tout cela! Ce sont des formes diverses de l'égoïsme, mais c'est de\r
+l'égoïsme! Si je songeais un peu aux autres? La première sainteté est de\r
+penser à autrui. Voyons, examinons. Moi excepté, moi effacé, moi oublié,\r
+qu'arrivera-t-il de tout ceci?--Si je me dénonce? on me prend. On lâche\r
+ce Champmathieu, on me remet aux galères, c'est bien. Et puis? Que se\r
+passe-t-il ici? Ah! ici, il y a un pays, une ville, des fabriques, une\r
+industrie, des ouvriers, des hommes, des femmes, des vieux grands-pères,\r
+des enfants, des pauvres gens! J'ai créé tout ceci, je fais vivre tout\r
+cela; partout où il y a une cheminée qui fume, c'est moi qui ai mis le\r
+tison dans le feu et la viande dans la marmite; j'ai fait l'aisance, la\r
+circulation, le crédit; avant moi il n'y avait rien; j'ai relevé,\r
+vivifié, animé, fécondé, stimulé, enrichi tout le pays; moi de moins,\r
+c'est l'âme de moins. Je m'ôte, tout meurt.--Et cette femme qui a tant\r
+souffert, qui a tant de mérites dans sa chute, dont j'ai causé sans le\r
+vouloir tout le malheur! Et cet enfant que je voulais aller chercher,\r
+que j'ai promis à la mère! Est-ce que je ne dois pas aussi quelque chose\r
+à cette femme, en réparation du mal que je lui ai fait? Si je disparais,\r
+qu'arrive-t-il? La mère meurt. L'enfant devient ce qu'il peut. Voilà ce\r
+qui se passe, si je me dénonce.--Si je ne me dénonce pas? Voyons, si je\r
+ne me dénonce pas? Après s'être fait cette question, il s'arrêta; il eut\r
+comme un moment d'hésitation et de tremblement; mais ce moment dura peu,\r
+et il se répondit avec calme:\r
+\r
+--Eh bien, cet homme va aux galères, c'est vrai, mais, que diable! il a\r
+volé! J'ai beau me dire qu'il n'a pas volé, il a volé! Moi, je reste\r
+ici, je continue. Dans dix ans j'aurai gagné dix millions, je les\r
+répands dans le pays, je n'ai rien à moi, qu'est-ce que cela me fait? Ce\r
+n'est pas pour moi ce que je fais! La prospérité de tous va croissant,\r
+les industries s'éveillent et s'excitent, les manufactures et les usines\r
+se multiplient, les familles, cent familles, mille familles! sont\r
+heureuses; la contrée se peuple; il naît des villages où il n'y a que\r
+des fermes, il naît des fermes où il n'y a rien; la misère disparaît, et\r
+avec la misère disparaissent la débauche, la prostitution, le vol, le\r
+meurtre, tous les vices, tous les crimes! Et cette pauvre mère élève son\r
+enfant! et voilà tout un pays riche et honnête! Ah çà, j'étais fou,\r
+j'étais absurde, qu'est-ce que je parlais donc de me dénoncer? Il faut\r
+faire attention, vraiment, et ne rien précipiter. Quoi! parce qu'il\r
+m'aura plu de faire le grand et le généreux,--c'est du mélodrame, après\r
+tout!--parce que je n'aurai songé qu'à moi, qu'à moi seul, quoi! pour\r
+sauver d'une punition peut-être un peu exagérée, mais juste au fond, on\r
+ne sait qui, un voleur, un drôle évidemment, il faudra que tout un pays\r
+périsse! il faudra qu'une pauvre femme crève à l'hôpital! qu'une pauvre\r
+petite fille crève sur le pavé! comme des chiens! Ah! mais c'est\r
+abominable! Sans même que la mère ait revu son enfant! sans que l'enfant\r
+ait presque connu sa mère! Et tout ça pour ce vieux gredin de voleur de\r
+pommes qui, à coup sûr, a mérité les galères pour autre chose, si ce\r
+n'est pour cela! Beaux scrupules qui sauvent un coupable et qui\r
+sacrifient des innocents, qui sauvent un vieux vagabond, lequel n'a plus\r
+que quelques années à vivre au bout du compte et ne sera guère plus\r
+malheureux au bagne que dans sa masure, et qui sacrifient toute une\r
+population, mères, femmes, enfants! Cette pauvre petite Cosette qui n'a\r
+que moi au monde et qui est sans doute en ce moment toute bleue de froid\r
+dans le bouge de ces Thénardier! Voilà encore des canailles ceux-là! Et\r
+je manquerais à mes devoirs envers tous ces pauvres êtres! Et je m'en\r
+irais me dénoncer! Et je ferais cette inepte sottise! Mettons tout au\r
+pis. Supposons qu'il y ait une mauvaise action pour moi dans ceci et que\r
+ma conscience me la reproche un jour, accepter, pour le bien d'autrui,\r
+ces reproches qui ne chargent que moi, cette mauvaise action qui ne\r
+compromet que mon âme, c'est là qu'est le dévouement, c'est là qu'est la\r
+vertu.\r
+\r
+Il se leva, il se remit à marcher. Cette fois il lui semblait qu'il\r
+était content. On ne trouve les diamants que dans les ténèbres de la\r
+terre; on ne trouve les vérités que dans les profondeurs de la pensée.\r
+Il lui semblait qu'après être descendu dans ces profondeurs, après avoir\r
+longtemps tâtonné au plus noir de ces ténèbres, il venait enfin de\r
+trouver un de ces diamants, une de ces vérités, et qu'il la tenait dans\r
+sa main; et il s'éblouissait à la regarder.\r
+\r
+--Oui, pensa-t-il, c'est cela. Je suis dans le vrai. J'ai la solution.\r
+Il faut finir par s'en tenir à quelque chose. Mon parti est pris.\r
+Laissons faire! Ne vacillons plus, ne reculons plus. Ceci est dans\r
+l'intérêt de tous, non dans le mien. Je suis Madeleine, je reste\r
+Madeleine. Malheur à celui qui est Jean Valjean! Ce n'est plus moi. Je\r
+ne connais pas cet homme, je ne sais plus ce que c'est, s'il se trouve\r
+que quelqu'un est Jean Valjean à cette heure, qu'il s'arrange! cela ne\r
+me regarde pas. C'est un nom de fatalité qui flotte dans la nuit, s'il\r
+s'arrête et s'abat sur une tête, tant pis pour elle!\r
+\r
+Il se regarda dans le petit miroir qui était sur sa cheminée, et dit:\r
+\r
+--Tiens! cela m'a soulagé de prendre une résolution! Je suis tout autre\r
+à présent.\r
+\r
+Il marcha encore quelques pas, puis il s'arrêta court:\r
+\r
+--Allons! dit-il, il ne faut hésiter devant aucune des conséquences de\r
+la résolution prise. Il y a encore des fils qui m'attachent à ce Jean\r
+Valjean. Il faut les briser! Il y a ici, dans cette chambre même, des\r
+objets qui m'accuseraient, des choses muettes qui seraient des témoins,\r
+c'est dit, il faut que tout cela disparaisse.\r
+\r
+Il fouilla dans sa poche, en tira sa bourse, l'ouvrit, et y prit une\r
+petite clef.\r
+\r
+Il introduisit cette clef dans une serrure dont on voyait à peine le\r
+trou, perdu qu'il était dans les nuances les plus sombres du dessin qui\r
+couvrait le papier collé sur le mur. Une cachette s'ouvrit, une espèce\r
+de fausse armoire ménagée entre l'angle de la muraille et le manteau de\r
+la cheminée. Il n'y avait dans cette cachette que quelques guenilles, un\r
+sarrau de toile bleue, un vieux pantalon, un vieux havresac, et un gros\r
+bâton d'épine ferré aux deux bouts. Ceux qui avaient vu Jean Valjean à\r
+l'époque où il traversait Digne, en octobre 1815, eussent aisément\r
+reconnu toutes les pièces de ce misérable accoutrement.\r
+\r
+Il les avait conservées comme il avait conservé les chandeliers\r
+d'argent, pour se rappeler toujours son point de départ. Seulement il\r
+cachait ceci qui venait du bagne, et il laissait voir les flambeaux qui\r
+venaient de l'évêque.\r
+\r
+Il jeta un regard furtif vers la porte, comme s'il eût craint qu'elle ne\r
+s'ouvrît malgré le verrou qui la fermait; puis d'un mouvement vif et\r
+brusque et d'une seule brassée, sans même donner un coup d'oeil à ces\r
+choses qu'il avait si religieusement et si périlleusement gardées\r
+pendant tant d'années, il prit tout, haillons, bâton, havresac, et jeta\r
+tout au feu. Il referma la fausse armoire, et, redoublant de\r
+précautions, désormais inutiles puisqu'elle était vide, en cacha la\r
+porte derrière un gros meuble qu'il y poussa.\r
+\r
+Au bout de quelques secondes, la chambre et le mur d'en face furent\r
+éclairés d'une grande réverbération rouge et tremblante. Tout brûlait.\r
+Le bâton d'épine pétillait et jetait des étincelles jusqu'au milieu de\r
+la chambre.\r
+\r
+Le havresac, en se consumant avec d'affreux chiffons qu'il contenait,\r
+avait mis à nu quelque chose qui brillait dans la cendre. En se\r
+penchant, on eût aisément reconnu une pièce d'argent. Sans doute la\r
+pièce de quarante sous volée au petit savoyard.\r
+\r
+Lui ne regardait pas le feu et marchait, allant et venant toujours du\r
+même pas.\r
+\r
+Tout à coup ses yeux tombèrent sur les deux flambeaux d'argent que la\r
+réverbération faisait reluire vaguement sur la cheminée.\r
+\r
+--Tiens! pensa-t-il, tout Jean Valjean est encore là-dedans. Il faut\r
+aussi détruire cela.\r
+\r
+Il prit les deux flambeaux.\r
+\r
+Il y avait assez de feu pour qu'on pût les déformer promptement et en\r
+faire une sorte de lingot méconnaissable.\r
+\r
+Il se pencha sur le foyer et s'y chauffa un instant. Il eut un vrai\r
+bien-être.--La bonne chaleur! dit-il.\r
+\r
+Il remua le brasier avec un des deux chandeliers. Une minute de plus, et\r
+ils étaient dans le feu. En ce moment il lui sembla qu'il entendait une\r
+voix qui criait au dedans de lui:\r
+\r
+--Jean Valjean! Jean Valjean!\r
+\r
+Ses cheveux se dressèrent, il devint comme un homme qui écoute une chose\r
+terrible.\r
+\r
+--Oui, c'est cela, achève! disait la voix. Complète ce que tu fais!\r
+détruis ces flambeaux! anéantis ce souvenir! oublie l'évêque! oublie\r
+tout! perds ce Champmathieu! va, c'est bien. Applaudis-toi! Ainsi, c'est\r
+convenu, c'est résolu, c'est dit, voilà un homme, voilà un vieillard qui\r
+ne sait ce qu'on lui veut, qui n'a rien fait peut-être, un innocent,\r
+dont ton nom fait tout le malheur, sur qui ton nom pèse comme un crime,\r
+qui va être pris pour toi, qui va être condamné, qui va finir ses jours\r
+dans l'abjection et dans l'horreur! c'est bien. Sois honnête homme, toi.\r
+Reste monsieur le maire, reste honorable et honoré, enrichis la ville,\r
+nourris des indigents, élève des orphelins, vis heureux, vertueux et\r
+admiré, et pendant ce temps-là, pendant que tu seras ici dans la joie et\r
+dans la lumière, il y aura quelqu'un qui aura ta casaque rouge, qui\r
+portera ton nom dans l'ignominie et qui traînera ta chaîne au bagne!\r
+Oui, c'est bien arrangé ainsi! Ah! misérable!\r
+\r
+La sueur lui coulait du front. Il attachait sur les flambeaux un oeil\r
+hagard. Cependant ce qui parlait en lui n'avait pas fini. La voix\r
+continuait:\r
+\r
+--Jean Valjean! il y aura autour de toi beaucoup de voix qui feront un\r
+grand bruit, qui parleront bien haut, et qui te béniront, et une seule\r
+que personne n'entendra et qui te maudira dans les ténèbres. Eh bien!\r
+écoute, infâme! toutes ces bénédictions retomberont avant d'arriver au\r
+ciel, et il n'y aura que la malédiction qui montera jusqu'à Dieu! Cette\r
+voix, d'abord toute faible et qui s'était élevée du plus obscur de sa\r
+conscience, était devenue par degrés éclatante et formidable, et il\r
+l'entendait maintenant à son oreille. Il lui semblait qu'elle était\r
+sortie de lui-même et qu'elle parlait à présent en dehors de lui. Il\r
+crut entendre les dernières paroles si distinctement qu'il regarda dans\r
+la chambre avec une sorte de terreur.\r
+\r
+--Y a-t-il quelqu'un ici? demanda-t-il à haute voix, et tout égaré.\r
+\r
+Puis il reprit avec un rire qui ressemblait au rire d'un idiot:\r
+\r
+--Que je suis bête! il ne peut y avoir personne.\r
+\r
+Il y avait quelqu'un; mais celui qui y était n'était pas de ceux que\r
+l'oeil humain peut voir.\r
+\r
+Il posa les flambeaux sur la cheminée.\r
+\r
+Alors il reprit cette marche monotone et lugubre qui troublait dans ses\r
+rêves et réveillait en sursaut l'homme endormi au-dessous de lui.\r
+\r
+Cette marche le soulageait et l'enivrait en même temps. Il semble que\r
+parfois dans les occasions suprêmes on se remue pour demander conseil à\r
+tout ce qu'on peut rencontrer en se déplaçant. Au bout de quelques\r
+instants il ne savait plus où il en était.\r
+\r
+Il reculait maintenant avec une égale épouvante devant les deux\r
+résolutions qu'il avait prises tour à tour. Les deux idées qui le\r
+conseillaient lui paraissaient aussi funestes l'une que l'autre.--Quelle\r
+fatalité! quelle rencontre que ce Champmathieu pris pour lui! Être\r
+précipité justement par le moyen que la providence paraissait d'abord\r
+avoir employé pour l'affermir!\r
+\r
+Il y eut un moment où il considéra l'avenir. Se dénoncer, grand Dieu! se\r
+livrer! Il envisagea avec un immense désespoir tout ce qu'il faudrait\r
+quitter, tout ce qu'il faudrait reprendre. Il faudrait donc dire adieu à\r
+cette existence si bonne, si pure, si radieuse, à ce respect de tous, à\r
+l'honneur, à la liberté! Il n'irait plus se promener dans les champs, il\r
+n'entendrait plus chanter les oiseaux au mois de mai, il ne ferait plus\r
+l'aumône aux petits enfants! Il ne sentirait plus la douceur des regards\r
+de reconnaissance et d'amour fixés sur lui! Il quitterait cette maison\r
+qu'il avait bâtie, cette chambre, cette petite chambre! Tout lui\r
+paraissait charmant à cette heure. Il ne lirait plus dans ces livres, il\r
+n'écrirait plus sur cette petite table de bois blanc! Sa vieille\r
+portière, la seule servante qu'il eût, ne lui monterait plus son café le\r
+matin. Grand Dieu! au lieu de cela, la chiourme, le carcan, la veste\r
+rouge, la chaîne au pied, la fatigue, le cachot, le lit de camp, toutes\r
+ces horreurs connues! À son âge, après avoir été ce qu'il était! Si\r
+encore il était jeune! Mais, vieux, être tutoyé par le premier venu,\r
+être fouillé par le garde-chiourme, recevoir le coup de bâton de\r
+l'argousin! avoir les pieds nus dans des souliers ferrés! tendre matin\r
+et soir sa jambe au marteau du rondier qui visite la manille! subir la\r
+curiosité des étrangers auxquels on dirait: _Celui-là, c'est le fameux\r
+Jean Valjean, qui a été maire à Montreuil-sur-mer_! Le soir, ruisselant\r
+de sueur, accablé de lassitude, le bonnet vert sur les yeux, remonter\r
+deux à deux, sous le fouet du sergent, l'escalier-échelle du bagne\r
+flottant! Oh! quelle misère! La destinée peut-elle donc être méchante\r
+comme un être intelligent et devenir monstrueuse comme le coeur humain!\r
+\r
+Et, quoi qu'il fît, il retombait toujours sur ce poignant dilemme qui\r
+était au fond de sa rêverie:--rester dans le paradis, et y devenir\r
+démon! rentrer dans l'enfer, et y devenir ange!\r
+\r
+Que faire, grand Dieu! que faire?\r
+\r
+La tourmente dont il était sorti avec tant de peine se déchaîna de\r
+nouveau en lui. Ses idées recommencèrent à se mêler. Elles prirent ce je\r
+ne sais quoi de stupéfié et de machinal qui est propre au désespoir. Ce\r
+nom de Romainville lui revenait sans cesse à l'esprit avec deux vers\r
+d'une chanson qu'il avait entendue autrefois. Il songeait que\r
+Romainville est un petit bois près Paris où les jeunes gens amoureux\r
+vont cueillir des lilas au mois d'avril.\r
+\r
+Il chancelait au dehors comme au dedans. Il marchait comme un petit\r
+enfant qu'on laisse aller seul.\r
+\r
+À de certains moments, luttant contre sa lassitude, il faisait effort\r
+pour ressaisir son intelligence. Il tâchait de se poser une dernière\r
+fois, et définitivement, le problème sur lequel il était en quelque\r
+sorte tombé d'épuisement. Faut-il se dénoncer? Faut-il se taire?--Il ne\r
+réussissait à rien voir de distinct. Les vagues aspects de tous les\r
+raisonnements ébauchés par sa rêverie tremblaient et se dissipaient l'un\r
+après l'autre en fumée. Seulement il sentait que, à quelque parti qu'il\r
+s'arrêtât, nécessairement, et sans qu'il fût possible d'y échapper,\r
+quelque chose de lui allait mourir; qu'il entrait dans un sépulcre à\r
+droite comme à gauche; qu'il accomplissait une agonie, l'agonie de son\r
+bonheur ou l'agonie de sa vertu.\r
+\r
+Hélas! toutes ses irrésolutions l'avaient repris. Il n'était pas plus\r
+avancé qu'au commencement.\r
+\r
+Ainsi se débattait sous l'angoisse cette malheureuse âme. Dix-huit cents\r
+ans avant cet homme infortuné, l'être mystérieux, en qui se résument\r
+toutes les saintetés et toutes les souffrances de l'humanité, avait\r
+aussi lui, pendant que les oliviers frémissaient au vent farouche de\r
+l'infini, longtemps écarté de la main l'effrayant calice qui lui\r
+apparaissait ruisselant d'ombre et débordant de ténèbres dans des\r
+profondeurs pleines d'étoiles.\r

+Chapitre IV\r
+\r
+Formes que prend la souffrance pendant le sommeil\r
+\r
+\r
+Trois heures du matin venaient de sonner, et il y avait cinq heures\r
+qu'il marchait ainsi, presque sans interruption lorsqu'il se laissa\r
+tomber sur sa chaise.\r
+\r
+Il s'y endormit et fit un rêve.\r
+\r
+Ce rêve, comme la plupart des rêves, ne se rapportait à la situation que\r
+par je ne sais quoi de funeste et de poignant, mais il lui fit\r
+impression. Ce cauchemar le frappa tellement que plus tard il l'a écrit.\r
+C'est un des papiers écrits de sa main qu'il a laissés. Nous croyons\r
+devoir transcrire ici cette chose textuellement.\r
+\r
+Quel que soit ce rêve, l'histoire de cette nuit serait incomplète si\r
+nous l'omettions. C'est la sombre aventure d'une âme malade.\r
+\r
+Le voici. Sur l'enveloppe nous trouvons cette ligne écrite: _Le rêve que\r
+j'ai eu cette nuit-là._\r
+\r
+«J'étais dans une campagne. Une grande campagne triste où il n'y avait\r
+pas d'herbe. Il ne me semblait pas qu'il fît jour ni qu'il fît nuit.\r
+\r
+«Je me promenais avec mon frère, le frère de mes années d'enfance, ce\r
+frère auquel je dois dire que je ne pense jamais et dont je ne me\r
+souviens presque plus.\r
+\r
+«Nous causions, et nous rencontrions des passants. Nous parlions d'une\r
+voisine que nous avions eue autrefois, et qui, depuis qu'elle demeurait\r
+sur la rue, travaillait la fenêtre toujours ouverte. Tout en causant,\r
+nous avions froid à cause de cette fenêtre ouverte.\r
+\r
+«Il n'y avait pas d'arbres dans la campagne.\r
+\r
+«Nous vîmes un homme qui passa près de nous. C'était un homme tout nu,\r
+couleur de cendre, monté sur un cheval couleur de terre. L'homme n'avait\r
+pas de cheveux; on voyait son crâne et des veines sur son crâne. Il\r
+tenait à la main une baguette qui était souple comme un sarment de vigne\r
+et lourde comme du fer. Ce cavalier passa et ne nous dit rien.\r
+\r
+«Mon frère me dit: Prenons par le chemin creux.\r
+\r
+«Il y avait un chemin creux où l'on ne voyait pas une broussaille ni un\r
+brin de mousse. Tout était couleur de terre, même le ciel. Au bout de\r
+quelques pas, on ne me répondit plus quand je parlais. Je m'aperçus que\r
+mon frère n'était plus avec moi.\r
+\r
+«J'entrai dans un village que je vis. Je songeai que ce devait être là\r
+Romainville (pourquoi Romainville?).\r
+\r
+«La première rue où j'entrai était déserte. J'entrai dans une seconde\r
+rue. Derrière l'angle que faisaient les deux rues, il y avait un homme\r
+debout contre le mur. Je dis à cet homme:--Quel est ce pays? où suis-je?\r
+L'homme ne répondit pas. Je vis la porte d'une maison ouverte, j'y\r
+entrai.\r
+\r
+«La première chambre était déserte. J'entrai dans la seconde. Derrière\r
+la porte de cette chambre, il y avait un homme debout contre le mur. Je\r
+demandai à cet homme:--À qui est cette maison? où suis-je? L'homme ne\r
+répondit pas. La maison avait un jardin.\r
+\r
+«Je sortis de la maison et j'entrai dans le jardin. Le jardin était\r
+désert. Derrière le premier arbre, je trouvai un homme qui se tenait\r
+debout. Je dis à cet homme:--Quel est ce jardin? où suis-je? L'homme ne\r
+répondit pas.\r
+\r
+«J'errai dans le village, et je m'aperçus que c'était une ville. Toutes\r
+les rues étaient désertes, toutes les portes étaient ouvertes. Aucun\r
+être vivant ne passait dans les rues, ne marchait dans les chambres ou\r
+ne se promenait dans les jardins. Mais il y avait derrière chaque angle\r
+de mur, derrière chaque porte, derrière chaque arbre, un homme debout\r
+qui se taisait. On n'en voyait jamais qu'un à la fois. Ces hommes me\r
+regardaient passer.\r
+\r
+«Je sortis de la ville et je me mis à marcher dans les champs.\r
+\r
+«Au bout de quelque temps, je me retournai, et je vis une grande foule\r
+qui venait derrière moi. Je reconnus tous les hommes que j'avais vus\r
+dans la ville. Ils avaient des têtes étranges. Ils ne semblaient pas se\r
+hâter, et cependant ils marchaient plus vite que moi. Ils ne faisaient\r
+aucun bruit en marchant. En un instant, cette foule me rejoignit et\r
+m'entoura. Les visages de ces hommes étaient couleur de terre.\r
+\r
+«Alors le premier que j'avais vu et questionné en entrant dans la ville\r
+me dit:--Où allez-vous? Est-ce que vous ne savez pas que vous êtes mort\r
+depuis longtemps?\r
+\r
+«J'ouvris la bouche pour répondre, et je m'aperçus qu'il n'y avait\r
+personne autour de moi.»\r
+\r
+Il se réveilla. Il était glacé. Un vent qui était froid comme le vent du\r
+matin faisait tourner dans leurs gonds les châssis de la croisée restée\r
+ouverte. Le feu s'était éteint. La bougie touchait à sa fin. Il était\r
+encore nuit noire.\r
+\r
+Il se leva, il alla à la fenêtre. Il n'y avait toujours pas d'étoiles au\r
+ciel.\r
+\r
+De sa fenêtre on voyait la cour de la maison et la rue. Un bruit sec et\r
+dur qui résonna tout à coup sur le sol lui fit baisser les yeux.\r
+\r
+Il vit au-dessous de lui deux étoiles rouges dont les rayons\r
+s'allongeaient et se raccourcissaient bizarrement dans l'ombre.\r
+\r
+Comme sa pensée était encore à demi submergée dans la brume des\r
+rêves.--tiens! songea-t-il, il n'y en a pas dans le ciel. Elles sont sur\r
+la terre maintenant.\r
+\r
+Cependant ce trouble se dissipa, un second bruit pareil au premier\r
+acheva de le réveiller; il regarda, et il reconnut que ces deux étoiles\r
+étaient les lanternes d'une voiture. À la clarté qu'elles jetaient, il\r
+put distinguer la forme de cette voiture. C'était un tilbury attelé d'un\r
+petit cheval blanc. Le bruit qu'il avait entendu, c'étaient les coups de\r
+pied du cheval sur le pavé.\r
+\r
+--Qu'est-ce que c'est que cette voiture? se dit-il. Qui est-ce qui vient\r
+donc si matin? En ce moment on frappa un petit coup à la porte de sa\r
+chambre.\r
+\r
+Il frissonna de la tête aux pieds, et cria d'une voix terrible:\r
+\r
+--Qui est là?\r
+\r
+Quelqu'un répondit:\r
+\r
+--Moi, monsieur le maire.\r
+\r
+Il reconnut la voix de la vieille femme, sa portière.\r
+\r
+--Eh bien, reprit-il, qu'est-ce que c'est?\r
+\r
+--Monsieur le maire, il est tout à l'heure cinq heures du matin.\r
+\r
+--Qu'est-ce que cela me fait?\r
+\r
+--Monsieur le maire, c'est le cabriolet.\r
+\r
+--Quel cabriolet?\r
+\r
+--Le tilbury.\r
+\r
+--Quel tilbury?\r
+\r
+--Est-ce que monsieur le maire n'a pas fait demander un tilbury?\r
+\r
+--Non, dit-il.\r
+\r
+--Le cocher dit qu'il vient chercher monsieur le maire.\r
+\r
+--Quel cocher?\r
+\r
+--Le cocher de M. Scaufflaire.\r
+\r
+--M. Scaufflaire?\r
+\r
+Ce nom le fit tressaillir comme si un éclair lui eût passé devant la\r
+face.\r
+\r
+--Ah! oui! reprit-il, M. Scaufflaire.\r
+\r
+Si la vieille femme l'eût pu voir en ce moment, elle eût été épouvantée.\r
+\r
+Il se fit un assez long silence. Il examinait d'un air stupide la flamme\r
+de la bougie et prenait autour de la mèche de la cire brûlante qu'il\r
+roulait dans ses doigts.\r
+\r
+La vieille attendait. Elle se hasarda pourtant à élever encore la voix:\r
+\r
+--Monsieur le maire, que faut-il que je réponde?\r
+\r
+--Dites que c'est bien, et que je descends.\r
+\r

+\r
+Chapitre V\r
+\r
+Bâtons dans les roues\r
+\r
+\r
+Le service des postes d'Arras à Montreuil-sur-mer se faisait encore à\r
+cette époque par de petites malles du temps de l'empire. Ces malles\r
+étaient des cabriolets à deux roues, tapissés de cuir fauve au dedans,\r
+suspendus sur des ressorts à pompe, et n'ayant que deux places, l'une\r
+pour le courrier, l'autre pour le voyageur. Les roues étaient armées de\r
+ces longs moyeux offensifs qui tiennent les autres voitures à distance\r
+et qu'on voit encore sur les routes d'Allemagne. Le coffre aux dépêches,\r
+immense boîte oblongue, était placé derrière le cabriolet et faisait\r
+corps avec lui. Ce coffre était peint en noir et le cabriolet en jaune.\r
+\r
+Ces voitures, auxquelles rien ne ressemble aujourd'hui, avaient je ne\r
+sais quoi de difforme et de bossu, et, quand on les voyait passer de\r
+loin et ramper dans quelque route à l'horizon, elles ressemblaient à ces\r
+insectes qu'on appelle, je crois, termites, et qui, avec un petit\r
+corsage, traînent un gros arrière-train. Elles allaient, du reste, fort\r
+vite. La malle partie d'Arras toutes les nuits à une heure, après le\r
+passage du courrier de Paris, arrivait à Montreuil-sur-mer un peu avant\r
+cinq heures du matin.\r
+\r
+Cette nuit-là, la malle qui descendait à Montreuil-sur-mer par la route\r
+de Hesdin accrocha, au tournant d'une rue, au moment où elle entrait\r
+dans la ville, un petit tilbury attelé d'un cheval blanc, qui venait en\r
+sens inverse et dans lequel il n'y avait qu'une personne, un homme\r
+enveloppé d'un manteau. La roue du tilbury reçut un choc assez rude. Le\r
+courrier cria à cet homme d'arrêter, mais le voyageur n'écouta pas, et\r
+continua sa route au grand trot.\r
+\r
+--Voilà un homme diablement pressé! dit le courrier.\r
+\r
+L'homme qui se hâtait ainsi, c'est celui que nous venons de voir se\r
+débattre dans des convulsions dignes à coup sûr de pitié.\r
+\r
+Où allait-il? Il n'eût pu le dire. Pourquoi se hâtait-il? Il ne savait.\r
+Il allait au hasard devant lui. Où? À Arras sans doute; mais il allait\r
+peut-être ailleurs aussi. Par moments il le sentait, et il tressaillait.\r
+\r
+Il s'enfonçait dans cette nuit comme dans un gouffre. Quelque chose le\r
+poussait, quelque chose l'attirait. Ce qui se passait en lui, personne\r
+ne pourrait le dire, tous le comprendront. Quel homme n'est entré, au\r
+moins une fois en sa vie, dans cette obscure caverne de l'inconnu?\r
+\r
+Du reste il n'avait rien résolu, rien décidé, rien arrêté, rien fait.\r
+Aucun des actes de sa conscience n'avait été définitif. Il était plus\r
+que jamais comme au premier moment. Pourquoi allait-il à Arras?\r
+\r
+Il se répétait ce qu'il s'était déjà dit en retenant le cabriolet de\r
+Scaufflaire,--que, quel que dût être le résultat, il n'y avait aucun\r
+inconvénient à voir de ses yeux, à juger les choses par lui-même;--que\r
+cela même était prudent, qu'il fallait savoir ce qui se passerait; qu'on\r
+ne pouvait rien décider sans avoir observé et scruté;--que de loin on se\r
+faisait des montagnes de tout; qu'au bout du compte, lorsqu'il aurait vu\r
+ce Champmathieu, quelque misérable, sa conscience serait probablement\r
+fort soulagée de le laisser aller au bagne à sa place;--qu'à la vérité\r
+il y aurait là Javert, et ce Brevet, ce Chenildieu, ce Cochepaille,\r
+anciens forçats qui l'avaient connu; mais qu'à coup sûr ils ne le\r
+reconnaîtraient pas;--bah! quelle idée!--que Javert en était à cent\r
+lieues;--que toutes les conjectures et toutes les suppositions étaient\r
+fixées sur ce Champmathieu, et que rien n'est entêté comme les\r
+suppositions et les conjectures;--qu'il n'y avait donc aucun danger. Que\r
+sans doute c'était un moment noir, mais qu'il en sortirait;--qu'après\r
+tout il tenait sa destinée, si mauvaise qu'elle voulût être, dans sa\r
+main;--qu'il en était le maître. Il se cramponnait à cette pensée.\r
+\r
+Au fond, pour tout dire, il eût mieux aimé ne point aller à Arras.\r
+\r
+Cependant il y allait.\r
+\r
+Tout en songeant, il fouettait le cheval, lequel trottait de ce bon trot\r
+réglé et sûr qui fait deux lieues et demie à l'heure.\r
+\r
+À mesure que le cabriolet avançait, il sentait quelque chose en lui qui\r
+reculait.\r
+\r
+Au point du jour il était en rase campagne; la ville de\r
+Montreuil-sur-mer était assez loin derrière lui. Il regarda l'horizon\r
+blanchir; il regarda, sans les voir, passer devant ses yeux toutes les\r
+froides figures d'une aube d'hiver. Le matin a ses spectres comme le\r
+soir. Il ne les voyait pas, mais, à son insu, et par une sorte de\r
+pénétration presque physique, ces noires silhouettes d'arbres et de\r
+collines ajoutaient à l'état violent de son âme je ne sais quoi de morne\r
+et de sinistre.\r
+\r
+Chaque fois qu'il passait devant une de ces maisons isolées qui côtoient\r
+parfois les routes, il se disait: il y a pourtant là-dedans des gens qui\r
+dorment!\r
+\r
+Le trot du cheval, les grelots du harnais, les roues sur le pavé,\r
+faisaient un bruit doux et monotone. Ces choses-là sont charmantes quand\r
+on est joyeux et lugubres quand on est triste. Il était grand jour\r
+lorsqu'il arriva à Hesdin. Il s'arrêta devant une auberge pour laisser\r
+souffler le cheval et lui faire donner l'avoine.\r
+\r
+Ce cheval était, comme l'avait dit Scaufflaire, de cette petite race du\r
+Boulonnais qui a trop de tête, trop de ventre et pas assez d'encolure,\r
+mais qui a le poitrail ouvert, la croupe large, la jambe sèche et fine\r
+et le pied solide; race laide, mais robuste et saine. L'excellente bête\r
+avait fait cinq lieues en deux heures et n'avait pas une goutte de sueur\r
+sur la croupe.\r
+\r
+Il n'était pas descendu du tilbury. Le garçon d'écurie qui apportait\r
+l'avoine se baissa tout à coup et examina la roue de gauche.\r
+\r
+--Allez-vous loin comme cela? dit cet homme.\r
+\r
+Il répondit, presque sans sortir de sa rêverie:\r
+\r
+--Pourquoi?\r
+\r
+--Venez-vous de loin? reprit le garçon.\r
+\r
+--De cinq lieues d'ici.\r
+\r
+--Ah!\r
+\r
+--Pourquoi dites-vous: ah?\r
+\r
+Le garçon se pencha de nouveau, resta un moment silencieux, l'oeil fixé\r
+sur la roue, puis se redressa en disant:\r
+\r
+--C'est que voilà une roue qui vient de faire cinq lieues, c'est\r
+possible, mais qui à coup sûr ne fera pas maintenant un quart de lieue.\r
+\r
+Il sauta à bas du tilbury.\r
+\r
+--Que dites-vous là, mon ami?\r
+\r
+--Je dis que c'est un miracle que vous ayez fait cinq lieues sans\r
+rouler, vous et votre cheval, dans quelque fossé de la grande route.\r
+Regardez plutôt.\r
+\r
+La roue en effet était gravement endommagée. Le choc de la malle-poste\r
+avait fendu deux rayons et labouré le moyeu dont l'écrou ne tenait plus.\r
+\r
+--Mon ami, dit-il au garçon d'écurie, il y a un charron ici?\r
+\r
+--Sans doute, monsieur.\r
+\r
+--Rendez-moi le service de l'aller chercher.\r
+\r
+--Il est là, à deux pas. Hé! maître Bourgaillard!\r
+\r
+Maître Bourgaillard, le charron, était sur le seuil de sa porte. Il vint\r
+examiner la roue et fit la grimace d'un chirurgien qui considère une\r
+jambe cassée.\r
+\r
+--Pouvez-vous raccommoder cette roue sur-le-champ?\r
+\r
+--Oui, monsieur.\r
+\r
+--Quand pourrai-je repartir?\r
+\r
+--Demain.\r
+\r
+--Demain!\r
+\r
+--Il y a une grande journée d'ouvrage. Est-ce que monsieur est pressé?\r
+\r
+--Très pressé. Il faut que je reparte dans une heure au plus tard.\r
+\r
+--Impossible, monsieur.\r
+\r
+--Je payerai tout ce qu'on voudra.\r
+\r
+--Impossible.\r
+\r
+--Eh bien! dans deux heures.\r
+\r
+--Impossible pour aujourd'hui. Il faut refaire deux rais et un moyeu.\r
+Monsieur ne pourra repartir avant demain.\r
+\r
+--L'affaire que j'ai ne peut attendre à demain. Si, au lieu de\r
+raccommoder cette roue, on la remplaçait?\r
+\r
+--Comment cela?\r
+\r
+--Vous êtes charron?\r
+\r
+--Sans doute, monsieur.\r
+\r
+--Est-ce que vous n'auriez pas une roue à me vendre? Je pourrais\r
+repartir tout de suite.\r
+\r
+--Une roue de rechange?\r
+\r
+--Oui.\r
+\r
+--Je n'ai pas une roue toute faite pour votre cabriolet. Deux roues font\r
+la paire. Deux roues ne vont pas ensemble au hasard.\r
+\r
+--En ce cas, vendez-moi une paire de roues.\r
+\r
+--Monsieur, toutes les roues ne vont pas à tous les essieux.\r
+\r
+--Essayez toujours.\r
+\r
+--C'est inutile, monsieur. Je n'ai à vendre que des roues de charrette.\r
+Nous sommes un petit pays ici.\r
+\r
+--Auriez-vous un cabriolet à me louer?\r
+\r
+Le maître charron, du premier coup d'oeil, avait reconnu que le tilbury\r
+était une voiture de louage. Il haussa les épaules.\r
+\r
+--Vous les arrangez bien, les cabriolets qu'on vous loue! j'en aurais un\r
+que je ne vous le louerais pas.\r
+\r
+--Eh bien, à me vendre?\r
+\r
+--Je n'en ai pas.\r
+\r
+--Quoi! pas une carriole? Je ne suis pas difficile, comme vous voyez.\r
+\r
+--Nous sommes un petit pays. J'ai bien là sous la remise, ajouta le\r
+charron, une vieille calèche qui est à un bourgeois de la ville qui me\r
+l'a donnée en garde et qui s'en sert tous les trente-six du mois. Je\r
+vous la louerais bien, qu'est-ce que cela me fait? mais il ne faudrait\r
+pas que le bourgeois la vît passer; et puis, c'est une calèche, il\r
+faudrait deux chevaux.\r
+\r
+--Je prendrai des chevaux de poste.\r
+\r
+--Où va monsieur?\r
+\r
+--À Arras.\r
+\r
+--Et monsieur veut arriver aujourd'hui?\r
+\r
+--Mais oui.\r
+\r
+--En prenant des chevaux de poste?\r
+\r
+--Pourquoi pas?\r
+\r
+--Est-il égal à monsieur d'arriver cette nuit à quatre heures du matin?\r
+\r
+--Non certes.\r
+\r
+--C'est que, voyez-vous bien, il y a une chose à dire, en prenant des\r
+chevaux de poste....\r
+\r
+--Monsieur a son passeport?\r
+\r
+--Oui.\r
+\r
+--Eh bien, en prenant des chevaux de poste, monsieur n'arrivera pas à\r
+Arras avant demain. Nous sommes un chemin de traverse. Les relais sont\r
+mal servis, les chevaux sont aux champs. C'est la saison des grandes\r
+charrues qui commence, il faut de forts attelages, et l'on prend les\r
+chevaux partout, à la poste comme ailleurs. Monsieur attendra au moins\r
+trois ou quatre heures à chaque relais. Et puis on va au pas. Il y a\r
+beaucoup de côtes à monter.\r
+\r
+--Allons, j'irai à cheval. Dételez le cabriolet. On me vendra bien une\r
+selle dans le pays.\r
+\r
+--Sans doute. Mais ce cheval-ci endure-t-il la selle?\r
+\r
+--C'est vrai, vous m'y faites penser. Il ne l'endure pas.\r
+\r
+--Alors....\r
+\r
+--Mais je trouverai bien dans le village un cheval à louer?\r
+\r
+--Un cheval pour aller à Arras d'une traite!\r
+\r
+--Oui.\r
+\r
+--Il faudrait un cheval comme on n'en a pas dans nos endroits. Il\r
+faudrait l'acheter d'abord, car on ne vous connaît pas. Mais ni à vendre\r
+ni à louer, ni pour cinq cents francs, ni pour mille, vous ne le\r
+trouveriez pas!\r
+\r
+--Comment faire?\r
+\r
+--Le mieux, là, en honnête homme, c'est que je raccommode la roue et que\r
+vous remettiez votre voyage à demain.\r
+\r
+--Demain il sera trop tard.\r
+\r
+--Dame!\r
+\r
+--N'y a-t-il pas la malle-poste qui va à Arras? Quand passe-t-elle?\r
+\r
+--La nuit prochaine. Les deux malles font le service la nuit, celle qui\r
+monte comme celle qui descend.\r
+\r
+--Comment! il vous faut une journée pour raccommoder cette roue?\r
+\r
+--Une journée, et une bonne!\r
+\r
+--En mettant deux ouvriers?\r
+\r
+--En en mettant dix!\r
+\r
+--Si on liait les rayons avec des cordes?\r
+\r
+--Les rayons, oui; le moyeu, non. Et puis la jante aussi est en mauvais\r
+état.\r
+\r
+--Y a-t-il un loueur de voitures dans la ville?\r
+\r
+--Non.\r
+\r
+--Y a-t-il un autre charron?\r
+\r
+Le garçon d'écurie et le maître charron répondirent en même temps en\r
+hochant la tête.\r
+\r
+--Non.\r
+\r
+Il sentit une immense joie.\r
+\r
+Il était évident que la providence s'en mêlait. C'était elle qui avait\r
+brisé la roue du tilbury et qui l'arrêtait en route. Il ne s'était pas\r
+rendu à cette espèce de première sommation; il venait de faire tous les\r
+efforts possibles pour continuer son voyage; il avait loyalement et\r
+scrupuleusement épuisé tous les moyens; il n'avait reculé ni devant la\r
+saison, ni devant la fatigue, ni devant la dépense; il n'avait rien à se\r
+reprocher. S'il n'allait pas plus loin, cela ne le regardait plus. Ce\r
+n'était plus sa faute, c'était, non le fait de sa conscience, mais le\r
+fait de la providence.\r
+\r
+Il respira. Il respira librement et à pleine poitrine pour la première\r
+fois depuis la visite de Javert. Il lui semblait que le poignet de fer\r
+qui lui serrait le coeur depuis vingt heures venait de le lâcher.\r
+\r
+Il lui paraissait que maintenant Dieu était pour lui, et se déclarait.\r
+\r
+Il se dit qu'il avait fait tout ce qu'il pouvait, et qu'à présent il\r
+n'avait qu'à revenir sur ses pas, tranquillement.\r
+\r
+Si sa conversation avec le charron eût eu lieu dans une chambre de\r
+l'auberge, elle n'eût point eu de témoins, personne ne l'eût entendue,\r
+les choses en fussent restées là, et il est probable que nous n'aurions\r
+eu à raconter aucun des événements qu'on va lire; mais cette\r
+conversation s'était faite dans la rue. Tout colloque dans la rue\r
+produit inévitablement un cercle. Il y a toujours des gens qui ne\r
+demandent qu'à être spectateurs. Pendant qu'il questionnait le charron,\r
+quelques allants et venants s'étaient arrêtés autour d'eux. Après avoir\r
+écouté pendant quelques minutes, un jeune garçon, auquel personne\r
+n'avait pris garde, s'était détaché du groupe en courant.\r
+\r
+Au moment où le voyageur, après la délibération intérieure que nous\r
+venons d'indiquer, prenait la résolution de rebrousser chemin, cet\r
+enfant revenait. Il était accompagné d'une vieille femme.\r
+\r
+--Monsieur, dit la femme, mon garçon me dit que vous avez envie de louer\r
+un cabriolet. Cette simple parole, prononcée par une vieille femme que\r
+conduisait un enfant, lui fit ruisseler la sueur dans les reins. Il crut\r
+voir la main qui l'avait lâché reparaître dans l'ombre derrière lui,\r
+toute prête à le reprendre.\r
+\r
+Il répondit:\r
+\r
+--Oui, bonne femme, je cherche un cabriolet à louer.\r
+\r
+Et il se hâta d'ajouter:\r
+\r
+--Mais il n'y en a pas dans le pays.\r
+\r
+--Si fait, dit la vieille.\r
+\r
+--Où ça donc? reprit le charron.\r
+\r
+--Chez moi, répliqua la vieille.\r
+\r
+Il tressaillit. La main fatale l'avait ressaisi.\r
+\r
+La vieille avait en effet sous un hangar une façon de carriole en osier.\r
+Le charron et le garçon d'auberge, désolés que le voyageur leur\r
+échappât, intervinrent.\r
+\r
+--C'était une affreuse guimbarde,--cela était posé à cru sur\r
+l'essieu,--il est vrai que les banquettes étaient suspendues à\r
+l'intérieur avec des lanières de cuir,--il pleuvait dedans,--les roues\r
+étaient rouillées et rongées d'humidité,--cela n'irait pas beaucoup plus\r
+loin que le tilbury,--une vraie patache!--Ce monsieur aurait bien tort\r
+de s'y embarquer,--etc., etc.\r
+\r
+Tout cela était vrai, mais cette guimbarde, cette patache, cette chose,\r
+quelle qu'elle fût, roulait sur ses deux roues et pouvait aller à Arras.\r
+\r
+Il paya ce qu'on voulut, laissa le tilbury à réparer chez le charron\r
+pour l'y retrouver à son retour, fit atteler le cheval blanc à la\r
+carriole, y monta, et reprit la route qu'il suivait depuis le matin.\r
+\r
+Au moment où la carriole s'ébranla, il s'avoua qu'il avait eu l'instant\r
+d'auparavant une certaine joie de songer qu'il n'irait point où il\r
+allait. Il examina cette joie avec une sorte de colère et la trouva\r
+absurde. Pourquoi de la joie à revenir en arrière? Après tout, il\r
+faisait ce voyage librement. Personne ne l'y forçait. Et, certainement,\r
+rien n'arriverait que ce qu'il voudrait bien.\r
+\r
+Comme il sortait de Hesdin, il entendit une voix qui lui criait:\r
+arrêtez! arrêtez! Il arrêta la carriole d'un mouvement vif dans lequel\r
+il y avait encore je ne sais quoi de fébrile et de convulsif qui\r
+ressemblait à de l'espérance.\r
+\r
+C'était le petit garçon de la vieille.\r
+\r
+--Monsieur, dit-il, c'est moi qui vous ai procuré la carriole.\r
+\r
+--Eh bien!\r
+\r
+--Vous ne m'avez rien donné.\r
+\r
+Lui qui donnait à tous et si facilement, il trouva cette prétention\r
+exorbitante et presque odieuse.\r
+\r
+--Ah! c'est toi, drôle? dit-il, tu n'auras rien!\r
+\r
+Il fouetta le cheval et repartit au grand trot.\r
+\r
+Il avait perdu beaucoup de temps à Hesdin, il eût voulu le rattraper. Le\r
+petit cheval était courageux et tirait comme deux; mais on était au mois\r
+de février, il avait plu, les routes étaient mauvaises. Et puis, ce\r
+n'était plus le tilbury. La carriole était dure et très lourde. Avec\r
+cela force montées.\r
+\r
+Il mit près de quatre heures pour aller de Hesdin à Saint-Pol. Quatre\r
+heures pour cinq lieues.\r
+\r
+À Saint-Pol il détela à la première auberge venue, et fit mener le\r
+cheval à l'écurie. Comme il l'avait promis à Scaufflaire, il se tint\r
+près du râtelier pendant que le cheval mangeait. Il songeait à des\r
+choses tristes et confuses.\r
+\r
+La femme de l'aubergiste entre dans l'écurie.\r
+\r
+--Est-ce que monsieur ne veut pas déjeuner?\r
+\r
+--Tiens, c'est vrai, dit-il, j'ai même bon appétit. Il suivit cette\r
+femme qui avait une figure fraîche et réjouie. Elle le conduisit dans\r
+une salle basse où il y avait des tables ayant pour nappes des toiles\r
+cirées.\r
+\r
+--Dépêchez-vous, reprit-il, il faut que je reparte. Je suis pressé.\r
+\r
+Une grosse servante flamande mit son couvert en toute hâte. Il regardait\r
+cette fille avec un sentiment de bien-être.\r
+\r
+--C'est là ce que j'avais, pensa-t-il. Je n'avais pas déjeuné.\r
+\r
+On le servit. Il se jeta sur le pain, mordit une bouchée, puis le reposa\r
+lentement sur la table et n'y toucha plus.\r
+\r
+Un routier mangeait à une autre table. Il dit à cet homme:\r
+\r
+--Pourquoi leur pain est-il donc si amer?\r
+\r
+Le routier était allemand et n'entendit pas.\r
+\r
+Il retourna dans l'écurie près du cheval.\r
+\r
+Une heure après, il avait quitté Saint-Pol et se dirigeait vers Tinques\r
+qui n'est qu'à cinq lieues d'Arras.\r
+\r
+Que faisait-il pendant ce trajet? À quoi pensait-il? Comme le matin, il\r
+regardait passer les arbres, les toits de chaume, les champs cultivés,\r
+et les évanouissements du paysage qui se disloque à chaque coude du\r
+chemin. C'est là une contemplation qui suffit quelquefois à l'âme et qui\r
+la dispense presque de penser. Voir mille objets pour la première et\r
+pour la dernière fois, quoi de plus mélancolique et de plus profond!\r
+Voyager, c'est naître et mourir à chaque instant. Peut-être, dans la\r
+région la plus vague de son esprit, faisait-il des rapprochements entre\r
+ces horizons changeants et l'existence humaine. Toutes les choses de la\r
+vie sont perpétuellement en fuite devant nous. Les obscurcissements et\r
+les clartés s'entremêlent: après un éblouissement, une éclipse; on\r
+regarde, on se hâte, on tend les mains pour saisir ce qui passe; chaque\r
+événement est un tournant de la route; et tout à coup on est vieux. On\r
+sent comme une secousse, tout est noir, on distingue une porte obscure,\r
+ce sombre cheval de la vie qui vous traînait s'arrête, et l'on voit\r
+quelqu'un de voilé et d'inconnu qui le dételle dans les ténèbres.\r
+\r
+Le crépuscule tombait au moment où des enfants qui sortaient de l'école\r
+regardèrent ce voyageur entrer dans Tinques. Il est vrai qu'on était\r
+encore aux jours courts de l'année. Il ne s'arrêta pas à Tinques. Comme\r
+il débouchait du village, un cantonnier qui empierrait la route dressa\r
+la tête et dit:\r
+\r
+--Voilà un cheval bien fatigué.\r
+\r
+La pauvre bête en effet n'allait plus qu'au pas.\r
+\r
+--Est-ce que vous allez à Arras? ajouta le cantonnier.\r
+\r
+--Oui.\r
+\r
+--Si vous allez de ce train, vous n'y arriverez pas de bonne heure.\r
+\r
+Il arrêta le cheval et demanda au cantonnier:\r
+\r
+--Combien y a-t-il encore d'ici à Arras?\r
+\r
+--Près de sept grandes lieues.\r
+\r
+--Comment cela? le livre de poste ne marque que cinq lieues et un quart.\r
+\r
+--Ah! reprit le cantonnier, vous ne savez donc pas que la route est en\r
+réparation? Vous allez la trouver coupée à un quart d'heure d'ici. Pas\r
+moyen d'aller plus loin.\r
+\r
+--Vraiment.\r
+\r
+--Vous prendrez à gauche, le chemin qui va à Carency, vous passerez la\r
+rivière; et, quand vous serez à Camblin, vous tournerez à droite; c'est\r
+la route de Mont-Saint-Éloy qui va à Arras.\r
+\r
+--Mais voilà la nuit, je me perdrai.\r
+\r
+--Vous n'êtes pas du pays?\r
+\r
+--Non.\r
+\r
+--Avec ça, c'est tout chemins de traverse. Tenez, Monsieur, reprit le\r
+cantonnier, voulez-vous que je vous donne un conseil? Votre cheval est\r
+las, rentrez dans Tinques. Il y a une bonne auberge. Couchez-y. Vous\r
+irez demain à Arras.\r
+\r
+--Il faut que j'y sois ce soir.\r
+\r
+--C'est différent. Alors allez tout de même à cette auberge et prenez-y\r
+un cheval de renfort. Le garçon du cheval vous guidera dans la traverse.\r
+\r
+Il suivit le conseil du cantonnier, rebroussa chemin, et une demi-heure\r
+après il repassait au même endroit, mais au grand trot, avec un bon\r
+cheval de renfort. Un garçon d'écurie qui s'intitulait postillon était\r
+assis sur le brancard de la carriole.\r
+\r
+Cependant il sentait qu'il perdait du temps.\r
+\r
+Il faisait tout à fait nuit.\r
+\r
+Ils s'engagèrent dans la traverse. La route devint affreuse. La carriole\r
+tombait d'une ornière dans l'autre. Il dit au postillon:\r
+\r
+--Toujours au trot, et double pourboire.\r
+\r
+Dans un cahot le palonnier cassa.\r
+\r
+--Monsieur, dit le postillon, voilà le palonnier cassé, je ne sais plus\r
+comment atteler mon cheval, cette route-ci est bien mauvaise la nuit; si\r
+vous vouliez revenir coucher à Tinques, nous pourrions être demain matin\r
+de bonne heure à Arras.\r
+\r
+Il répondit:\r
+\r
+--As-tu un bout de corde et un couteau?\r
+\r
+--Oui, monsieur.\r
+\r
+Il coupa une branche d'arbre et en fit un palonnier.\r
+\r
+Ce fut encore une perte de vingt minutes; mais ils repartirent au galop.\r
+\r
+La plaine était ténébreuse. Des brouillards bas, courts et noirs\r
+rampaient sur les collines et s'en arrachaient comme des fumées. Il y\r
+avait des lueurs blanchâtres dans les nuages. Un grand vent qui venait\r
+de la mer faisait dans tous les coins de l'horizon le bruit de quelqu'un\r
+qui remue des meubles. Tout ce qu'on entrevoyait avait des attitudes de\r
+terreur. Que de choses frissonnent sous ces vastes souffles de la nuit!\r
+\r
+Le froid le pénétrait. Il n'avait pas mangé depuis la veille. Il se\r
+rappelait vaguement son autre course nocturne dans la grande plaine aux\r
+environs de Digne. Il y avait huit ans; et cela lui semblait hier.\r
+\r
+Une heure sonna à quelque clocher lointain. Il demanda au garçon:\r
+\r
+--Quelle est cette heure?\r
+\r
+--Sept heures, monsieur. Nous serons à Arras à huit. Nous n'avons plus\r
+que trois lieues. En ce moment il fit pour la première fois cette\r
+réflexion--en trouvant étrange qu'elle ne lui fût pas venue plus\r
+tôt--que c'était peut-être inutile, toute la peine qu'il prenait; qu'il\r
+ne savait seulement pas l'heure du procès; qu'il aurait dû au moins s'en\r
+informer; qu'il était extravagant d'aller ainsi devant soi sans savoir\r
+si cela servirait à quelque chose.--Puis il ébaucha quelques calculs\r
+dans son esprit:--qu'ordinairement les séances des cours d'assises\r
+commençaient à neuf heures du matin;--que cela ne devait pas être long,\r
+cette affaire-là;--que le vol de pommes, ce serait très court;--qu'il\r
+n'y aurait plus ensuite qu'une question d'identité;--quatre ou cinq\r
+dépositions, peu de chose à dire pour les avocats;--qu'il allait\r
+arriver lorsque tout serait fini!\r
+\r
+Le postillon fouettait les chevaux. Ils avaient passé la rivière et\r
+laissé derrière eux Mont-Saint-Éloy.\r
+\r
+La nuit devenait de plus en plus profonde.\r
+\r
+\r
+\r
+\r
+Chapitre VI\r
+\r
+La soeur Simplice mise à l'épreuve\r
+\r
+\r
+Cependant, en ce moment-là même, Fantine était dans la joie.\r
+\r
+Elle avait passé une très mauvaise nuit. Toux affreuse, redoublement de\r
+fièvre; elle avait eu des songes. Le matin, à la visite du médecin, elle\r
+délirait. Il avait eu l'air alarmé et avait recommandé qu'on le prévînt\r
+dès que M. Madeleine viendrait.\r
+\r
+Toute la matinée elle fut morne, parla peu, et fit des plis à ses draps\r
+en murmurant à voix basse des calculs qui avaient l'air d'être des\r
+calculs de distances. Ses yeux étaient caves et fixes. Ils paraissaient\r
+presque éteints, et puis, par moments, ils se rallumaient et\r
+resplendissaient comme des étoiles. Il semble qu'aux approches d'une\r
+certaine heure sombre, la clarté du ciel emplisse ceux que quitte la\r
+clarté de la terre.\r
+\r
+Chaque fois que la soeur Simplice lui demandait comment elle se\r
+trouvait, elle répondait invariablement:\r
+\r
+--Bien. Je voudrais voir monsieur Madeleine.\r
+\r
+Quelques mois auparavant, à ce moment où Fantine venait de perdre sa\r
+dernière pudeur, sa dernière honte et sa dernière joie, elle était\r
+l'ombre d'elle-même; maintenant elle en était le spectre. Le mal\r
+physique avait complété l'oeuvre du mal moral. Cette créature de\r
+vingt-cinq ans avait le front ridé, les joues flasques, les narines\r
+pincées, les dents déchaussées, le teint plombé, le cou osseux, les\r
+clavicules saillantes, les membres chétifs, la peau terreuse, et ses\r
+cheveux blonds poussaient mêlés de cheveux gris. Hélas! comme la maladie\r
+improvise la vieillesse! À midi, le médecin revint, il fit quelques\r
+prescriptions, s'informa si M. le maire avait paru à l'infirmerie, et\r
+branla la tête.\r
+\r
+M. Madeleine venait d'habitude à trois heures voir la malade. Comme\r
+l'exactitude était de la bonté, il était exact.\r
+\r
+Vers deux heures et demie, Fantine commença à s'agiter. Dans l'espace de\r
+vingt minutes, elle demanda plus de dix fois à la religieuse:\r
+\r
+--Ma soeur, quelle heure est-il?\r
+\r
+Trois heures sonnèrent. Au troisième coup, Fantine se dressa sur son\r
+séant, elle qui d'ordinaire pouvait à peine remuer dans son lit; elle\r
+joignit dans une sorte d'étreinte convulsive ses deux mains décharnées\r
+et jaunes, et la religieuse entendit sortir de sa poitrine un de ces\r
+soupirs profonds qui semblent soulever un accablement. Puis Fantine se\r
+tourna et regarda la porte.\r
+\r
+Personne n'entra; la porte ne s'ouvrit point.\r
+\r
+Elle resta ainsi un quart d'heure, l'oeil attaché sur la porte, immobile\r
+et comme retenant son haleine. La soeur n'osait lui parler. L'église\r
+sonna trois heures un quart. Fantine se laissa retomber sur l'oreiller.\r
+\r
+Elle ne dit rien et se remit à faire des plis à son drap. La demi-heure\r
+passa, puis l'heure. Personne ne vint.\r
+\r
+Chaque fois que l'horloge sonnait, Fantine se dressait et regardait du\r
+côté de la porte, puis elle retombait.\r
+\r
+On voyait clairement sa pensée, mais elle ne prononçait aucun nom, elle\r
+ne se plaignait pas, elle n'accusait pas. Seulement elle toussait d'une\r
+façon lugubre. On eût dit que quelque chose d'obscur s'abaissait sur\r
+elle. Elle était livide et avait les lèvres bleues. Elle souriait par\r
+moments.\r
+\r
+Cinq heures sonnèrent. Alors la soeur l'entendit qui disait très bas et\r
+doucement:\r
+\r
+--Mais puisque je m'en vais demain, il a tort de ne pas venir\r
+aujourd'hui!\r
+\r
+La soeur Simplice elle-même était surprise du retard de M. Madeleine.\r
+\r
+Cependant Fantine regardait le ciel de son lit. Elle avait l'air de\r
+chercher à se rappeler quelque chose. Tout à coup elle se mit à chanter\r
+d'une voix faible comme un souffle. La religieuse écouta. Voici ce que\r
+Fantine chantait:\r
+\r
+ _Nous achèterons de bien belles choses_\r
+ _En nous promenant le long des faubourgs._\r
+ _Les bleuets sont bleus, les roses sont roses,_\r
+ _Les bleuets sont bleus, j'aime mes amours._\r
+ _La vierge Marie auprès de mon poêle_\r
+ _Est venue hier en manteau brodé,_\r
+ _Et m'a dit:--Voici, caché sous mon voile,_\r
+ _Le petit qu'un jour tu m'as demandé._\r
+ _Courez à la ville, ayez de la toile,_\r
+ _Achetez du fil, achetez un dé._\r
+ _Nous achèterons de bien belles choses_\r
+ _En nous promenant le long des faubourgs._\r
+ _Bonne sainte Vierge, auprès de mon poêle_\r
+ _J'ai mis un berceau de rubans orné_\r
+ _Dieu me donnerait sa plus belle étoile,_\r
+ _J'aime mieux l'enfant que tu m'as donné._\r
+ --_Madame, que faire avec cette toile?_\r
+ --_Faites un trousseau pour mon nouveau-né._\r
+ _Les bleuets sont bleus, les roses sont roses,_\r
+ _Les bleuets sont bleus, j'aime mes amours._\r
+ --_Lavez cette toile._\r
+ --_Où?_--_Dans la rivière._\r
+ _Faites-en, sans rien gâter ni salir,_\r
+ _Une belle jupe avec sa brassière_\r
+ _Que je veux broder et de fleurs emplir._\r
+ --_L'enfant n'est plus là, madame, qu'en faire?_\r
+ --_Faites-en un drap pour m'ensevelir._\r
+ _Nous achèterons de bien belles choses_\r
+ _En nous promenant le long des faubourgs._\r
+ _Les bleuets sont bleus, les roses sont roses,_\r
+ _Les bleuets sont bleus, j'aime mes amours._\r
+\r
+Cette chanson était une vieille romance de berceuse avec laquelle\r
+autrefois elle endormait sa petite Cosette, et qui ne s'était pas\r
+offerte à son esprit depuis cinq ans qu'elle n'avait plus son enfant.\r
+Elle chantait cela d'une voix si triste et sur un air si doux que\r
+c'était à faire pleurer, même une religieuse. La soeur, habituée aux\r
+choses austères, sentit une larme lui venir.\r
+\r
+L'horloge sonna six heures. Fantine ne parut pas entendre. Elle semblait\r
+ne plus faire attention à aucune chose autour d'elle.\r
+\r
+La soeur Simplice envoya une fille de service s'informer près de la\r
+portière de la fabrique si M. le maire était rentré et s'il ne monterait\r
+pas bientôt à l'infirmerie. La fille revint au bout de quelques minutes.\r
+\r
+Fantine était toujours immobile et paraissait attentive à des idées\r
+qu'elle avait.\r
+\r
+La servante raconta très bas à la soeur Simplice que M. le maire était\r
+parti le matin même avant six heures dans un petit tilbury attelé d'un\r
+cheval blanc, par le froid qu'il faisait, qu'il était parti seul, pas\r
+même de cocher, qu'on ne savait pas le chemin qu'il avait pris, que des\r
+personnes disaient l'avoir vu tourner par la route d'Arras, que d'autres\r
+assuraient l'avoir rencontré sur la route de Paris. Qu'en s'en allant il\r
+avait été comme à l'ordinaire très doux, et qu'il avait seulement dit à\r
+la portière qu'on ne l'attendît pas cette nuit.\r
+\r
+Pendant que les deux femmes, le dos tourné au lit de la Fantine,\r
+chuchotaient, la soeur questionnant, la servante conjecturant, la\r
+Fantine, avec cette vivacité fébrile de certaines maladies organiques\r
+qui mêle les mouvements libres de la santé à l'effrayante maigreur de la\r
+mort, s'était mise à genoux sur son lit, ses deux poings crispés appuyés\r
+sur le traversin, et, la tête passée par l'intervalle des rideaux, elle\r
+écoutait. Tout à coup elle cria:\r
+\r
+--Vous parlez là de monsieur Madeleine! pourquoi parlez-vous tout bas?\r
+Qu'est-ce qu'il fait? Pourquoi ne vient-il pas?\r
+\r
+Sa voix était si brusque et si rauque que les deux femmes crurent\r
+entendre une voix d'homme; elles se retournèrent effrayées.\r
+\r
+--Répondez donc! cria Fantine.\r
+\r
+La servante balbutia:\r
+\r
+--La portière m'a dit qu'il ne pourrait pas venir aujourd'hui.\r
+\r
+--Mon enfant, dit la soeur, tenez-vous tranquille, recouchez-vous.\r
+\r
+Fantine, sans changer d'attitude, reprit d'une voix haute et avec un\r
+accent tout à la fois impérieux et déchirant:\r
+\r
+--Il ne pourra venir? Pourquoi cela? Vous savez la raison. Vous la\r
+chuchotiez là entre vous. Je veux la savoir.\r
+\r
+La servante se hâta de dire à l'oreille de la religieuse:\r
+\r
+--Répondez qu'il est occupé au conseil municipal.\r
+\r
+La soeur Simplice rougit légèrement; c'était un mensonge que la servante\r
+lui proposait. D'un autre côté il lui semblait bien que dire la vérité à\r
+la malade ce serait sans doute lui porter un coup terrible et que cela\r
+était grave dans l'état où était Fantine. Cette rougeur dura peu. La\r
+soeur leva sur Fantine son oeil calme et triste, et dit:\r
+\r
+--Monsieur le maire est parti.\r
+\r
+Fantine se redressa et s'assit sur ses talons. Ses yeux étincelèrent.\r
+Une joie inouïe rayonna sur cette physionomie douloureuse.\r
+\r
+--Parti! s'écria-t-elle. Il est allé chercher Cosette!\r
+\r
+Puis elle tendit ses deux mains vers le ciel et tout son visage devint\r
+ineffable. Ses lèvres remuaient; elle priait à voix basse.\r
+\r
+Quand sa prière fut finie:\r
+\r
+--Ma soeur, dit-elle, je veux bien me recoucher, je vais faire tout ce\r
+qu'on voudra; tout à l'heure j'ai été méchante, je vous demande pardon\r
+d'avoir parlé si haut, c'est très mal de parler haut, je le sais bien,\r
+ma bonne soeur, mais voyez-vous, je suis très contente. Le bon Dieu est\r
+bon, monsieur Madeleine est bon, figurez-vous qu'il est allé chercher ma\r
+petite Cosette à Montfermeil.\r
+\r
+Elle se recoucha, aida la religieuse à arranger l'oreiller et baisa une\r
+petite croix d'argent qu'elle avait au cou et que la soeur Simplice lui\r
+avait donnée.\r
+\r
+--Mon enfant, dit la soeur, tâchez de reposer maintenant, et ne parlez\r
+plus.\r
+\r
+Fantine prit dans ses mains moites la main de la soeur, qui souffrait de\r
+lui sentir cette sueur.\r
+\r
+--Il est parti ce matin pour aller à Paris. Au fait il n'a pas même\r
+besoin de passer par Paris. Montfermeil, c'est un peu à gauche en\r
+venant. Vous rappelez-vous comme il me disait hier quand je lui parlais\r
+de Cosette: bientôt, bientôt? C'est une surprise qu'il veut me faire.\r
+Vous savez? il m'avait fait signer une lettre pour la reprendre aux\r
+Thénardier. Ils n'auront rien à dire, pas vrai? Ils rendront Cosette.\r
+Puisqu'ils sont payés. Les autorités ne souffriraient pas qu'on garde un\r
+enfant quand on est payé. Ma soeur, ne me faites pas signe qu'il ne faut\r
+pas que je parle. Je suis extrêmement heureuse, je vais très bien, je\r
+n'ai plus de mal du tout, je vais revoir Cosette, j'ai même très faim.\r
+Il y a près de cinq ans que je ne l'ai vue. Vous ne vous figurez pas,\r
+vous, comme cela vous tient, les enfants! Et puis elle sera si gentille,\r
+vous verrez! Si vous saviez, elle a de si jolis petits doigts roses!\r
+D'abord elle aura de très belles mains. À un an, elle avait des mains\r
+ridicules. Ainsi!--Elle doit être grande à présent. Cela vous a sept\r
+ans. C'est une demoiselle. Je l'appelle Cosette, mais elle s'appelle\r
+Euphrasie. Tenez, ce matin, je regardais de la poussière qui était sur\r
+la cheminée et j'avais bien l'idée comme cela que je reverrais bientôt\r
+Cosette. Mon Dieu! comme on a tort d'être des années sans voir ses\r
+enfants! on devrait bien réfléchir que la vie n'est pas éternelle! Oh!\r
+comme il est bon d'être parti, monsieur le maire! C'est vrai ça, qu'il\r
+fait bien froid? avait-il son manteau au moins? Il sera ici demain,\r
+n'est-ce pas? Ce sera demain fête. Demain matin, ma soeur, vous me ferez\r
+penser à mettre mon petit bonnet qui a de la dentelle. Montfermeil,\r
+c'est un pays. J'ai fait cette route-là, à pied, dans le temps. Il y a\r
+eu bien loin pour moi. Mais les diligences vont très vite! Il sera ici\r
+demain avec Cosette. Combien y a-t-il d'ici Montfermeil?\r
+\r
+La soeur, qui n'avait aucune idée des distances, répondit:\r
+\r
+--Oh! je crois bien qu'il pourra être ici demain.\r
+\r
+--Demain! demain! dit Fantine, je verrai Cosette demain! Voyez-vous,\r
+bonne soeur du bon Dieu, je ne suis plus malade. Je suis folle. Je\r
+danserais, si on voulait.\r
+\r
+Quelqu'un qui l'eût vue un quart d'heure auparavant n'y eût rien\r
+compris. Elle était maintenant toute rose, elle parlait d'une voix vive\r
+et naturelle, toute sa figure n'était qu'un sourire. Par moments elle\r
+riait en se parlant tout bas. Joie de mère, c'est presque joie d'enfant.\r
+\r
+--Eh bien, reprit la religieuse, vous voilà heureuse, obéissez-moi, ne\r
+parlez plus.\r
+\r
+Fantine posa sa tête sur l'oreiller et dit à demi-voix:\r
+\r
+--Oui, recouche-toi, sois sage puisque tu vas avoir ton enfant. Elle a\r
+raison, soeur Simplice. Tous ceux qui sont ici ont raison.\r
+\r
+Et puis, sans bouger, sans remuer la tête, elle se mit à regarder\r
+partout avec ses yeux tout grands ouverts et un air joyeux, et elle ne\r
+dit plus rien.\r
+\r
+La soeur referma ses rideaux, espérant qu'elle s'assoupirait.\r
+\r
+Entre sept et huit heures le médecin vint. N'entendant aucun bruit, il\r
+crut que Fantine dormait, entra doucement et s'approcha du lit sur la\r
+pointe du pied. Il entrouvrit les rideaux, et à la lueur de la veilleuse\r
+il vit les grands yeux calmes de Fantine qui le regardaient.\r
+\r
+Elle lui dit:\r
+\r
+--Monsieur, n'est-ce pas, on me laissera la coucher à côté de moi dans\r
+un petit lit?\r
+\r
+Le médecin crut qu'elle délirait. Elle ajouta:\r
+\r
+--Regardez plutôt, il y a juste de la place.\r
+\r
+Le médecin prit à part la soeur Simplice qui lui expliqua la chose, que\r
+M. Madeleine était absent pour un jour ou deux, et que, dans le doute,\r
+on n'avait pas cru devoir détromper la malade qui croyait monsieur le\r
+maire parti pour Montfermeil; qu'il était possible en somme qu'elle eût\r
+deviné juste. Le médecin approuva.\r
+\r
+Il se rapprocha du lit de Fantine, qui reprit:\r
+\r
+--C'est que, voyez-vous, le matin, quand elle s'éveillera, je lui dirai\r
+bonjour à ce pauvre chat, et la nuit, moi qui ne dors pas, je\r
+l'entendrai dormir. Sa petite respiration si douce, cela me fera du\r
+bien.\r
+\r
+--Donnez-moi votre main, dit le médecin.\r
+\r
+Elle tendit son bras, et s'écria en riant.\r
+\r
+--Ah! tiens! au fait, c'est vrai, vous ne savez pas c'est que je suis\r
+guérie. Cosette arrive demain.\r
+\r
+Le médecin fut surpris. Elle était mieux. L'oppression était moindre. Le\r
+pouls avait repris de la force. Une sorte de vie survenue tout à coup\r
+ranimait ce pauvre être épuisé.\r
+\r
+--Monsieur le docteur, reprit-elle, la soeur vous a-t-elle dit que\r
+monsieur le maire était allé chercher le chiffon?\r
+\r
+Le médecin recommanda le silence et qu'on évitât toute émotion pénible.\r
+Il prescrivit une infusion de quinquina pur, et, pour le cas où la\r
+fièvre reprendrait dans la nuit, une potion calmante. En s'en allant, il\r
+dit à la soeur:\r
+\r
+--Cela va mieux. Si le bonheur voulait qu'en effet monsieur le maire\r
+arrivât demain avec l'enfant, qui sait? il y a des crises si étonnantes,\r
+on a vu de grandes joies arrêter court des maladies; je sais bien que\r
+celle-ci est une maladie organique, et bien avancée, mais c'est un tel\r
+mystère que tout cela! Nous la sauverions peut-être.\r
+\r
+\r
+\r
+\r
+Chapitre VII\r
+\r
+Le voyageur arrivé prend ses précautions pour repartir.\r
+\r
+\r
+Il était près de huit heures du soir quand la carriole que nous avons\r
+laissée en route entra sous la porte cochère de l'hôtel de la Poste\r
+à Arras. L'homme que nous avons suivi jusqu'à ce moment en descendit,\r
+répondit d'un air distrait aux empressements des gens de l'auberge,\r
+renvoya le cheval de renfort, et conduisit lui-même le petit cheval\r
+blanc à l'écurie; puis il poussa la porte d'une salle de billard qui\r
+était au rez-de-chaussée, s'y assit, et s'accouda sur une table. Il\r
+avait mis quatorze heures à ce trajet qu'il comptait faire en six.\r
+Il se rendait la justice que ce n'était pas sa faute; mais au fond il\r
+n'en était pas fâché.\r
+\r
+La maîtresse de l'hôtel entra.\r
+\r
+--Monsieur couche-t-il? monsieur soupe-t-il?\r
+\r
+Il fit un signe de tête négatif.\r
+\r
+--Le garçon d'écurie dit que le cheval de monsieur est bien fatigué!\r
+\r
+Ici il rompit le silence.\r
+\r
+--Est-ce que le cheval ne pourra pas repartir demain matin?\r
+\r
+--Oh! monsieur! il lui faut au moins deux jours de repos.\r
+\r
+Il demanda:\r
+\r
+--N'est-ce pas ici le bureau de poste?\r
+\r
+--Oui, monsieur.\r
+\r
+L'hôtesse le mena à ce bureau; il montra son passeport et s'informa s'il\r
+y avait moyen de revenir cette nuit même à Montreuil-sur-mer par la\r
+malle; la place à côté du courrier était justement vacante; il la retint\r
+et la paya.\r
+\r
+--Monsieur, dit le buraliste, ne manquez pas d'être ici pour partir à\r
+une heure précise du matin.\r
+\r
+Cela fait, il sortit de l'hôtel et se mit à marcher dans la ville.\r
+\r
+Il ne connaissait pas Arras, les rues étaient obscures, et il allait au\r
+hasard. Cependant il semblait s'obstiner à ne pas demander son chemin\r
+aux passants. Il traversa la petite rivière Crinchon et se trouva dans\r
+un dédale de ruelles étroites où il se perdit. Un bourgeois cheminait\r
+avec un falot. Après quelque hésitation, il prit le parti de s'adresser\r
+à ce bourgeois, non sans avoir d'abord regardé devant et derrière lui,\r
+comme s'il craignait que quelqu'un n'entendit la question qu'il allait\r
+faire.\r
+\r
+--Monsieur, dit-il, le palais de justice, s'il vous plaît?\r
+\r
+--Vous n'êtes pas de la ville, monsieur? répondit le bourgeois qui était\r
+un assez vieux homme, eh bien, suivez-moi. Je vais précisément du côté\r
+du palais de justice, c'est-à-dire du côté de l'hôtel de la préfecture.\r
+Car on répare en ce moment le palais, et provisoirement les tribunaux\r
+ont leurs audiences à la préfecture.\r
+\r
+--Est-ce là, demanda-t-il, qu'on tient les assises?\r
+\r
+--Sans doute, monsieur. Voyez-vous, ce qui est la préfecture aujourd'hui\r
+était l'évêché avant la révolution. Monsieur de Conzié, qui était évêque\r
+en quatre-vingt-deux, y a fait bâtir une grande salle. C'est dans cette\r
+grande salle qu'on juge.\r
+\r
+Chemin faisant, le bourgeois lui dit:\r
+\r
+--Si c'est un procès que monsieur veut voir, il est un peu tard.\r
+Ordinairement les séances finissent à six heures.\r
+\r
+Cependant, comme ils arrivaient sur la grande place, le bourgeois lui\r
+montra quatre longues fenêtres éclairées sur la façade d'un vaste\r
+bâtiment ténébreux.\r
+\r
+--Ma foi, monsieur, vous arrivez à temps, vous avez du bonheur.\r
+Voyez-vous ces quatre fenêtres? c'est la cour d'assises. Il y a de la\r
+lumière. Donc ce n'est pas fini. L'affaire aura traîné en longueur et on\r
+fait une audience du soir. Vous vous intéressez à cette affaire? Est-ce\r
+que c'est un procès criminel? Est-ce que vous êtes témoin?\r
+\r
+Il répondit:\r
+\r
+--Je ne viens pour aucune affaire, j'ai seulement à parler à un avocat.\r
+\r
+--C'est différent, dit le bourgeois. Tenez, monsieur, voici la porte. Où\r
+est le factionnaire. Vous n'aurez qu'à monter le grand escalier.\r
+\r
+Il se conforma aux indications du bourgeois, et, quelques minutes après,\r
+il était dans une salle où il y avait beaucoup de monde et où des\r
+groupes mêlés d'avocats en robe chuchotaient çà et là.\r
+\r
+C'est toujours une chose qui serre le coeur de voir ces attroupements\r
+d'hommes vêtus de noir qui murmurent entre eux à voix basse sur le seuil\r
+des chambres de justice. Il est rare que la charité et la pitié sortent\r
+de toutes ces paroles. Ce qui en sort le plus souvent, ce sont des\r
+condamnations faites d'avance. Tous ces groupes semblent à l'observateur\r
+qui passe et qui rêve autant de ruches sombres où des espèces d'esprits\r
+bourdonnants construisent en commun toutes sortes d'édifices ténébreux.\r
+\r
+Cette salle, spacieuse et éclairée d'une seule lampe, était une ancienne\r
+antichambre de l'évêché et servait de salle des pas perdus. Une porte à\r
+deux battants, fermée en ce moment, la séparait de la grande chambre où\r
+siégeait la cour d'assises.\r
+\r
+L'obscurité était telle qu'il ne craignit pas de s'adresser au premier\r
+avocat qu'il rencontra.\r
+\r
+--Monsieur, dit-il, où en est-on?\r
+\r
+--C'est fini, dit l'avocat.\r
+\r
+--Fini!\r
+\r
+Ce mot fut répété d'un tel accent que l'avocat se retourna.\r
+\r
+--Pardon, monsieur, vous êtes peut-être un parent?\r
+\r
+--Non. Je ne connais personne ici. Et y a-t-il eu condamnation?\r
+\r
+--Sans doute. Cela n'était guère possible autrement.\r
+\r
+--Aux travaux forcés?...\r
+\r
+--À perpétuité.\r
+\r
+Il reprit d'une voix tellement faible qu'on l'entendait à peine:\r
+\r
+--L'identité a donc été constatée?\r
+\r
+--Quelle identité? répondit l'avocat. Il n'y avait pas d'identité à\r
+constater. L'affaire était simple. Cette femme avait tué son enfant,\r
+l'infanticide a été prouvé, le jury a écarté la préméditation, on l'a\r
+condamnée à vie.\r
+\r
+--C'est donc une femme? dit-il.\r
+\r
+--Mais sûrement. La fille Limosin. De quoi me parlez-vous donc?\r
+\r
+--De rien. Mais puisque c'est fini, comment se fait-il que la salle soit\r
+encore éclairée?\r
+\r
+--C'est pour l'autre affaire qu'on a commencée il y a à peu près deux\r
+heures.\r
+\r
+--Quelle autre affaire?\r
+\r
+--Oh! celle-là est claire aussi. C'est une espèce de gueux, un\r
+récidiviste, un galérien, qui a volé. Je ne sais plus trop son nom. En\r
+voilà un qui vous a une mine de bandit. Rien que pour avoir cette\r
+figure-là, je l'enverrais aux galères.\r
+\r
+--Monsieur, demanda-t-il, y a-t-il moyen de pénétrer dans la salle?\r
+\r
+--Je ne crois vraiment pas. Il y a beaucoup de foule. Cependant\r
+l'audience est suspendue. Il y a des gens qui sont sortis, et, à la\r
+reprise de l'audience, vous pourrez essayer.\r
+\r
+--Par où entre-t-on?\r
+\r
+--Par cette grande porte.\r
+\r
+L'avocat le quitta. En quelques instants, il avait éprouvé, presque en\r
+même temps, presque mêlées, toutes les émotions possibles. Les paroles\r
+de cet indifférent lui avaient tour à tour traversé le coeur comme des\r
+aiguilles de glace et comme des lames de feu. Quand il vit que rien\r
+n'était terminé, il respira; mais il n'eût pu dire si ce qu'il\r
+ressentait était du contentement ou de la douleur.\r
+\r
+Il s'approcha de plusieurs groupes et il écouta ce qu'on disait. Le rôle\r
+de la session étant très chargé, le président avait indiqué pour ce même\r
+jour deux affaires simples et courtes. On avait commencé par\r
+l'infanticide, et maintenant on en était au forçat, au récidiviste, au\r
+"cheval de retour". Cet homme avait volé des pommes, mais cela ne\r
+paraissait pas bien prouvé; ce qui était prouvé, c'est qu'il avait été\r
+déjà aux galères à Toulon. C'est ce qui faisait son affaire mauvaise. Du\r
+reste, l'interrogatoire de l'homme était terminé et les dépositions des\r
+témoins; mais il y avait encore les plaidoiries de l'avocat et le\r
+réquisitoire du ministère public; cela ne devait guère finir avant\r
+minuit. L'homme serait probablement condamné; l'avocat général était\r
+très bon--et ne manquait pas ses accusés--c'était un garçon d'esprit qui\r
+faisait des vers.\r
+\r
+Un huissier se tenait debout près de la porte qui communiquait avec la\r
+salle des assises. Il demanda à cet huissier:\r
+\r
+--Monsieur, la porte va-t-elle bientôt s'ouvrir?\r
+\r
+--Elle ne s'ouvrira pas, dit l'huissier.\r
+\r
+--Comment! on ne l'ouvrira pas à la reprise de l'audience? est-ce que\r
+l'audience n'est pas suspendue?\r
+\r
+--L'audience vient d'être reprise, répondit l'huissier, mais la porte ne\r
+se rouvrira pas.\r
+\r
+--Pourquoi?\r
+\r
+--Parce que la salle est pleine.\r
+\r
+--Quoi? il n'y a plus une place?\r
+\r
+--Plus une seule. La porte est fermée. Personne ne peut plus entrer.\r
+\r
+L'huissier ajouta après un silence:\r
+\r
+--Il y a bien encore deux ou trois places derrière monsieur le\r
+président, mais monsieur le président n'y admet que les fonctionnaires\r
+publics.\r
+\r
+Cela dit, l'huissier lui tourna le dos.\r
+\r
+Il se retira la tête baissée, traversa l'antichambre et redescendit\r
+l'escalier lentement, comme hésitant à chaque marche. Il est probable\r
+qu'il tenait conseil avec lui-même. Le violent combat qui se livrait en\r
+lui depuis la veille n'était pas fini; et, à chaque instant, il en\r
+traversait quelque nouvelle péripétie. Arrivé sur le palier de\r
+l'escalier, il s'adossa à la rampe et croisa les bras. Tout à coup il\r
+ouvrit sa redingote, prit son portefeuille, en tira un crayon, déchira\r
+une feuille, et écrivit rapidement sur cette feuille à la lueur du\r
+réverbère cette ligne:--_M. Madeleine, maire de Montreuil-sur-mer_.\r
+Puis il remonta l'escalier à grands pas, fendit la foule, marcha droit à\r
+l'huissier, lui remit le papier, et lui dit avec autorité:\r
+\r
+--Portez ceci à monsieur le président.\r
+\r
+L'huissier prit le papier, y jeta un coup d'oeil et obéit.\r
+\r
+\r
+\r
+\r
+Chapitre VIII\r
+\r
+Entrée de faveur\r
+\r
+\r
+Sans qu'il s'en doutât, le maire de Montreuil-sur-mer avait une sorte de\r
+célébrité. Depuis sept ans que sa réputation de vertu remplissait tout\r
+le bas Boulonnais, elle avait fini par franchir les limites d'un petit\r
+pays et s'était répandue dans les deux ou trois départements voisins.\r
+Outre le service considérable qu'il avait rendu au chef-lieu en y\r
+restaurant l'industrie des verroteries noires, il n'était pas une des\r
+cent quarante et une communes de l'arrondissement de Montreuil-sur-mer\r
+qui ne lui dût quelque bienfait. Il avait su même au besoin aider et\r
+féconder les industries des autres arrondissements. C'est ainsi qu'il\r
+avait dans l'occasion soutenu de son crédit et de ses fonds la fabrique\r
+de tulle de Boulogne, la filature de lin à la mécanique de Frévent et la\r
+manufacture hydraulique de toiles de Boubers-sur-Canche. Partout on\r
+prononçait avec vénération le nom de M. Madeleine. Arras et Douai\r
+enviaient son maire à l'heureuse petite ville de Montreuil-sur-mer.\r
+\r
+Le conseiller à la cour royale de Douai, qui présidait cette session des\r
+assises à Arras, connaissait comme tout le monde ce nom si profondément\r
+et si universellement honoré. Quand l'huissier, ouvrant discrètement la\r
+porte qui communiquait de la chambre du conseil à l'audience, se pencha\r
+derrière le fauteuil du président et lui remit le papier où était écrite\r
+la ligne qu'on vient de lire, en ajoutant: _Ce monsieur désire assister\r
+à l'audience_, le président fit un vif mouvement de déférence, saisit\r
+une plume, écrivit quelques mots au bas du papier, et le rendit à\r
+l'huissier en lui disant: Faites entrer.\r
+\r
+L'homme malheureux dont nous racontons l'histoire était resté près de la\r
+porte de la salle à la même place et dans la même attitude où l'huissier\r
+l'avait quitté. Il entendit, à travers sa rêverie, quelqu'un qui lui\r
+disait: Monsieur veut-il bien me faire l'honneur de me suivre? C'était\r
+ce même huissier qui lui avait tourné le dos l'instant d'auparavant et\r
+qui maintenant le saluait jusqu'à terre. L'huissier en même temps lui\r
+remit le papier. Il le déplia, et, comme il se rencontrait qu'il était\r
+près de la lampe, il put lire:\r
+\r
+«Le président de la cour d'assises présente son respect à M. Madeleine.»\r
+\r
+Il froissa le papier entre ses mains, comme si ces quelques mots eussent\r
+eu pour lui un arrière-goût étrange et amer.\r
+\r
+Il suivit l'huissier.\r
+\r
+Quelques minutes après, il se trouvait seul dans une espèce de cabinet\r
+lambrissé, d'un aspect sévère, éclairé par deux bougies posées sur une\r
+table à tapis vert. Il avait encore dans l'oreille les dernières paroles\r
+de l'huissier qui venait de le quitter--«Monsieur, vous voici dans la\r
+chambre du conseil; vous n'avez qu'à tourner le bouton de cuivre de\r
+cette porte, et vous vous trouverez dans l'audience derrière le fauteuil\r
+de monsieur le président.»--Ces paroles se mêlaient dans sa pensée à un\r
+souvenir vague de corridors étroits et d'escaliers noirs qu'il venait de\r
+parcourir.\r
+\r
+L'huissier l'avait laissé seul. Le moment suprême était arrivé. Il\r
+cherchait à se recueillir sans pouvoir y parvenir. C'est surtout aux\r
+heures où l'on aurait le plus besoin de les rattacher aux réalités\r
+poignantes de la vie que tous les fils de la pensée se rompent dans le\r
+cerveau. Il était dans l'endroit même où les juges délibèrent et\r
+condamnent. Il regardait avec une tranquillité stupide cette chambre\r
+paisible et redoutable où tant d'existences avaient été brisées, où son\r
+nom allait retentir tout à l'heure, et que sa destinée traversait en ce\r
+moment. Il regardait la muraille, puis il se regardait lui-même,\r
+s'étonnant que ce fût cette chambre et que ce fût lui.\r
+\r
+Il n'avait pas mangé depuis plus de vingt-quatre heures, il était brisé\r
+par les cahots de la carriole, mais il ne le sentait pas; il lui\r
+semblait qu'il ne sentait rien.\r
+\r
+Il s'approcha d'un cadre noir qui était accroché au mur et qui contenait\r
+sous verre une vieille lettre autographe de Jean-Nicolas Pache, maire de\r
+Paris et ministre, datée, sans doute par erreur, du _9 juin an II_, et\r
+dans laquelle Pache envoyait à la commune la liste des ministres et des\r
+députés tenus en arrestation chez eux. Un témoin qui l'eût pu voir et\r
+qui l'eût observé en cet instant eût sans doute imaginé Fantine et\r
+Cosette.\r
+\r
+Tout en rêvant, il se retourna, et ses yeux rencontrèrent le bouton de\r
+cuivre de la porte qui le séparait de la salle des assises. Il avait\r
+presque oublié cette porte. Son regard, d'abord calme, s'y arrêta, resta\r
+attaché à ce bouton de cuivre, puis devint effaré et fixe, et\r
+s'empreignit peu à peu d'épouvante. Des gouttes de sueur lui sortaient\r
+d'entre les cheveux et ruisselaient sur ses tempes.\r
+\r
+À un certain moment, il fit avec une sorte d'autorité mêlée de rébellion\r
+ce geste indescriptible qui veut dire et qui dit si bien: _Pardieu! qui\r
+est-ce qui m'y force?_ Puis il se tourna vivement, vit devant lui la\r
+porte par laquelle il était entré, y alla, l'ouvrit, et sortit. Il\r
+n'était plus dans cette chambre, il était dehors, dans un corridor, un\r
+corridor long, étroit, coupé de degrés et de guichets, faisant toutes\r
+sortes d'angles, éclairé çà et là de réverbères pareils à des veilleuses\r
+de malades, le corridor par où il était venu. Il respira, il écouta;\r
+aucun bruit derrière lui, aucun bruit devant lui; il se mit à fuir comme\r
+si on le poursuivait.\r
+\r
+Quand il eut doublé plusieurs des coudes de ce couloir, il écouta\r
+encore. C'était toujours le même silence et la même ombre autour de lui.\r
+Il était essoufflé, il chancelait, il s'appuya au mur. La pierre était\r
+froide, sa sueur était glacée sur son front, il se redressa en\r
+frissonnant.\r
+\r
+Alors, là, seul, debout dans cette obscurité, tremblant de froid et\r
+d'autre chose peut-être, il songea.\r
+\r
+Il avait songé toute la nuit, il avait songé toute la journée; il\r
+n'entendait plus en lui qu'une voix qui disait: hélas!\r
+\r
+Un quart d'heure s'écoula ainsi. Enfin, il pencha la tête, soupira avec\r
+angoisse, laissa pendre ses bras, et revint sur ses pas. Il marchait\r
+lentement et comme accablé. Il semblait que quelqu'un l'eût atteint dans\r
+sa fuite et le ramenât.\r
+\r
+Il rentra dans la chambre du conseil. La première chose qu'il aperçut,\r
+ce fut la gâchette de la porte. Cette gâchette, ronde et en cuivre poli,\r
+resplendissait pour lui comme une effroyable étoile. Il la regardait\r
+comme une brebis regarderait l'oeil d'un tigre.\r
+\r
+Ses yeux ne pouvaient s'en détacher.\r
+\r
+De temps en temps il faisait un pas et se rapprochait de la porte.\r
+\r
+S'il eût écouté, il eût entendu, comme une sorte de murmure confus, le\r
+bruit de la salle voisine; mais il n'écoutait pas, et il n'entendait\r
+pas.\r
+\r
+Tout à coup, sans qu'il sût lui-même comment, il se trouva près de la\r
+porte. Il saisit convulsivement le bouton; la porte s'ouvrit.\r
+\r
+Il était dans la salle d'audience.\r
+\r
+\r
+\r
+\r
+Chapitre IX\r
+\r
+Un lieu où des convictions sont en train de se former\r
+\r
+\r
+Il fit un pas, referma machinalement la porte derrière lui, et resta\r
+debout, considérant ce qu'il voyait.\r
+\r
+C'était une assez vaste enceinte à peine éclairée, tantôt pleine de\r
+rumeur, tantôt pleine de silence, où tout l'appareil d'un procès\r
+criminel se développait avec sa gravité mesquine et lugubre au milieu de\r
+la foule.\r
+\r
+À un bout de la salle, celui où il se trouvait, des juges à l'air\r
+distrait, en robe usée, se rongeant les ongles ou fermant les paupières;\r
+à l'autre bout, une foule en haillons; des avocats dans toutes sortes\r
+d'attitudes; des soldats au visage honnête et dur; de vieilles boiseries\r
+tachées, un plafond sale, des tables couvertes d'une serge plutôt jaune\r
+que verte, des portes noircies par les mains; à des clous plantés dans\r
+le lambris, des quinquets d'estaminet donnant plus de fumée que de\r
+clarté; sur les tables, des chandelles dans des chandeliers de cuivre;\r
+l'obscurité, la laideur, la tristesse; et de tout cela se dégageait une\r
+impression austère et auguste, car on y sentait cette grande chose\r
+humaine qu'on appelle la loi et cette grande chose divine qu'on appelle\r
+la justice.\r
+\r
+Personne dans cette foule ne fit attention à lui. Tous les regards\r
+convergeaient vers un point unique, un banc de bois adossé à une petite\r
+porte, le long de la muraille, à gauche du président. Sur ce banc, que\r
+plusieurs chandelles éclairaient, il y avait un homme entre deux\r
+gendarmes.\r
+\r
+Cet homme, c'était l'homme.\r
+\r
+Il ne le chercha pas, il le vit. Ses yeux allèrent là naturellement,\r
+comme s'ils avaient su d'avance où était cette figure.\r
+\r
+Il crut se voir lui-même, vieilli, non pas sans doute absolument\r
+semblable de visage, mais tout pareil d'attitude et d'aspect, avec ces\r
+cheveux hérissés, avec cette prunelle fauve et inquiète, avec cette\r
+blouse, tel qu'il était le jour où il entrait à Digne, plein de haine et\r
+cachant dans son âme ce hideux trésor de pensées affreuses qu'il avait\r
+mis dix-neuf ans à ramasser sur le pavé du bagne.\r
+\r
+Il se dit avec un frémissement:\r
+\r
+--Mon Dieu! est-ce que je redeviendrai ainsi?\r
+\r
+Cet être paraissait au moins soixante ans. Il avait je ne sais quoi de\r
+rude, de stupide et d'effarouché.\r
+\r
+Au bruit de la porte, on s'était rangé pour lui faire place, le\r
+président avait tourné la tête, et comprenant que le personnage qui\r
+venait d'entrer était M. le maire de Montreuil-sur-mer, il l'avait\r
+salué. L'avocat général, qui avait vu M. Madeleine à Montreuil-sur-mer\r
+où des opérations de son ministère l'avaient plus d'une fois appelé, le\r
+reconnut, et salua également. Lui s'en aperçut à peine. Il était en\r
+proie à une sorte d'hallucination; il regardait.\r
+\r
+Des juges, un greffier, des gendarmes, une foule de têtes cruellement\r
+curieuses, il avait déjà vu cela une fois, autrefois, il y avait\r
+vingt-sept ans. Ces choses funestes, il les retrouvait; elles étaient\r
+là, elles remuaient, elles existaient. Ce n'était plus un effort de sa\r
+mémoire, un mirage de sa pensée, c'étaient de vrais gendarmes et de\r
+vrais juges, une vraie foule et de vrais hommes en chair et en os. C'en\r
+était fait, il voyait reparaître et revivre autour de lui, avec tout ce\r
+que la réalité a de formidable, les aspects monstrueux de son passé.\r
+\r
+Tout cela était béant devant lui.\r
+\r
+Il en eut horreur, il ferma les yeux, et s'écria au plus profond de son\r
+âme: jamais!\r
+\r
+Et par un jeu tragique de la destinée qui faisait trembler toutes ses\r
+idées et le rendait presque fou, c'était un autre lui-même qui était là!\r
+Cet homme qu'on jugeait, tous l'appelaient Jean Valjean!\r
+\r
+Il avait sous les yeux, vision inouïe, une sorte de représentation du\r
+moment le plus horrible de sa vie, jouée par son fantôme.\r
+\r
+Tout y était, c'était le même appareil, la même heure de nuit, presque\r
+les mêmes faces de juges, de soldats et de spectateurs. Seulement,\r
+au-dessus de la tête du président, il y avait un crucifix, chose qui\r
+manquait aux tribunaux du temps de sa condamnation. Quand on l'avait\r
+jugé, Dieu était absent.\r
+\r
+Une chaise était derrière lui; il s'y laissa tomber, terrifié de l'idée\r
+qu'on pouvait le voir. Quand il fut assis, il profita d'une pile de\r
+cartons qui était sur le bureau des juges pour dérober son visage à\r
+toute la salle. Il pouvait maintenant voir sans être vu. Peu à peu il se\r
+remit. Il rentra pleinement dans le sentiment du réel; il arriva à cette\r
+phase de calme où l'on peut écouter.\r
+\r
+M. Bamatabois était au nombre des jurés. Il chercha Javert, mais il ne\r
+le vit pas. Le banc des témoins lui était caché par la table du\r
+greffier. Et puis, nous venons de le dire, la salle était à peine\r
+éclairée.\r
+\r
+Au moment où il était entré, l'avocat de l'accusé achevait sa\r
+plaidoirie. L'attention de tous était excitée au plus haut point;\r
+l'affaire durait depuis trois heures. Depuis trois heures, cette foule\r
+regardait plier peu à peu sous le poids d'une vraisemblance terrible un\r
+homme, un inconnu, une espèce d'être misérable, profondément stupide ou\r
+profondément habile. Cet homme, on le sait déjà, était un vagabond qui\r
+avait été trouvé dans un champ, emportant une branche chargée de pommes\r
+mûres, cassée à un pommier dans un clos voisin, appelé le clos Pierron.\r
+Qui était cet homme? Une enquête avait eu lieu; des témoins venaient\r
+d'être entendus, ils avaient été unanimes, des lumières avaient jailli\r
+de tout le débat. L'accusation disait:\r
+\r
+--Nous ne tenons pas seulement un voleur de fruits, un maraudeur; nous\r
+tenons là, dans notre main, un bandit, un relaps en rupture de ban, un\r
+ancien forçat, un scélérat des plus dangereux, un malfaiteur appelé Jean\r
+Valjean que la justice recherche depuis longtemps, et qui, il y a huit\r
+ans, en sortant du bagne de Toulon, a commis un vol de grand chemin à\r
+main armée sur la personne d'un enfant savoyard appelé Petit-Gervais,\r
+crime prévu par l'article 383 du code pénal, pour lequel nous nous\r
+réservons de le poursuivre ultérieurement, quand l'identité sera\r
+judiciairement acquise. Il vient de commettre un nouveau vol. C'est un\r
+cas de récidive. Condamnez-le pour le fait nouveau; il sera jugé plus\r
+tard pour le fait ancien.\r
+\r
+Devant cette accusation, devant l'unanimité des témoins, l'accusé\r
+paraissait surtout étonné. Il faisait des gestes et des signes qui\r
+voulaient dire non, ou bien il considérait le plafond. Il parlait avec\r
+peine, répondait avec embarras, mais de la tête aux pieds toute sa\r
+personne niait. Il était comme un idiot en présence de toutes ces\r
+intelligences rangées en bataille autour de lui, et comme un étranger au\r
+milieu de cette société qui le saisissait. Cependant il y allait pour\r
+lui de l'avenir le plus menaçant, la vraisemblance croissait à chaque\r
+minute, et toute cette foule regardait avec plus d'anxiété que lui-même\r
+cette sentence pleine de calamités qui penchait sur lui de plus en plus.\r
+Une éventualité laissait même entrevoir, outre le bagne, la peine de\r
+mort possible, si l'identité était reconnue et si l'affaire\r
+Petit-Gervais se terminait plus tard par une condamnation. Qu'était-ce\r
+que cet homme? De quelle nature était son apathie? Etait-ce imbécillité\r
+ou ruse? Comprenait-il trop, ou ne comprenait-il pas du tout? Questions\r
+qui divisaient la foule et semblaient partager le jury. Il y avait dans\r
+ce procès ce qui effraye et ce qui intrigue; le drame n'était pas\r
+seulement sombre, il était obscur. Le défenseur avait assez bien plaidé,\r
+dans cette langue de province qui a longtemps constitué l'éloquence du\r
+barreau et dont usaient jadis tous les avocats, aussi bien à Paris qu'à\r
+Romorantin ou à Montbrison, et qui aujourd'hui, étant devenue classique,\r
+n'est plus guère parlée que par les orateurs officiels du parquet,\r
+auxquels elle convient par sa sonorité grave et son allure majestueuse;\r
+langue où un mari s'appelle un époux, une femme, une épouse, Paris, le\r
+centre des arts et de la civilisation, le roi, le monarque, monseigneur\r
+l'évêque, un saint pontife, l'avocat général, l'éloquent interprète de\r
+la vindicte, la plaidoirie, les accents qu'on vient d'entendre, le\r
+siècle de Louis XIV, le grand siècle, un théâtre, le temple de\r
+Melpomène, la famille régnante, l'auguste sang de nos rois, un concert,\r
+une solennité musicale, monsieur le général commandant le département,\r
+l'illustre guerrier qui, etc., les élèves du séminaire, ces tendres\r
+lévites, les erreurs imputées aux journaux, l'imposture qui distille son\r
+venin dans les colonnes de ces organes, etc., etc.--L'avocat donc avait\r
+commencé par s'expliquer sur le vol des pommes,--chose malaisée en beau\r
+style; mais Bénigne Bossuet lui-même a été obligé de faire allusion à\r
+une poule en pleine oraison funèbre, et il s'en est tiré avec pompe.\r
+L'avocat avait établi que le vol de pommes n'était pas matériellement\r
+prouvé.--Son client, qu'en sa qualité de défenseur, il persistait à\r
+appeler Champmathieu, n'avait été vu de personne escaladant le mur ou\r
+cassant la branche. On l'avait arrêté nanti de cette branche (que\r
+l'avocat appelait plus volontiers rameau); mais il disait l'avoir\r
+trouvée à terre et ramassée. Où était la preuve du contraire?--Sans\r
+doute cette branche avait été cassée et dérobée après escalade, puis\r
+jetée là par le maraudeur alarmé; sans doute il y avait un voleur. Mais\r
+qu'est-ce qui prouvait que ce voleur était Champmathieu? Une seule\r
+chose. Sa qualité d'ancien forçat. L'avocat ne niait pas que cette\r
+qualité ne parût malheureusement bien constatée; l'accusé avait résidé à\r
+Faverolles; l'accusé y avait été émondeur; le nom de Champmathieu\r
+pouvait bien avoir pour origine Jean Mathieu; tout cela était vrai;\r
+enfin quatre témoins reconnaissaient sans hésiter et positivement\r
+Champmathieu pour être le galérien Jean Valjean; à ces indications, à\r
+ces témoignages, l'avocat ne pouvait opposer que la dénégation de son\r
+client, dénégation intéressée; mais en supposant qu'il fût le forçat\r
+Jean Valjean, cela prouvait-il qu'il fût le voleur des pommes? C'était\r
+une présomption, tout au plus; non une preuve. L'accusé, cela était\r
+vrai, et le défenseur «dans sa bonne foi» devait en convenir, avait\r
+adopté «un mauvais système de défense»--Il s'obstinait à nier tout, le\r
+vol et sa qualité de forçat. Un aveu sur ce dernier point eût mieux\r
+valu, à coup sûr, et lui eût concilié l'indulgence de ses juges;\r
+l'avocat le lui avait conseillé; mais l'accusé s'y était refusé\r
+obstinément, croyant sans doute sauver tout en n'avouant rien. C'était\r
+un tort; mais ne fallait-il pas considérer la brièveté de cette\r
+intelligence? Cet homme était visiblement stupide. Un long malheur au\r
+bagne, une longue misère hors du bagne, l'avaient abruti, etc., etc. Il\r
+se défendait mal, était-ce une raison pour le condamner? Quant à\r
+l'affaire Petit-Gervais, l'avocat n'avait pas à la discuter, elle\r
+n'était point dans la cause. L'avocat concluait en suppliant le jury et\r
+la cour, si l'identité de Jean Valjean leur paraissait évidente, de lui\r
+appliquer les peines de police qui s'adressent au condamné en rupture de\r
+ban, et non le châtiment épouvantable qui frappe le forçat récidiviste.\r
+\r
+L'avocat général répliqua au défenseur. Il fut violent et fleuri, comme\r
+sont habituellement les avocats généraux.\r
+\r
+Il félicita le défenseur de sa «loyauté», et profita habilement de cette\r
+loyauté. Il atteignit l'accusé par toutes les concessions que l'avocat\r
+avait faites. L'avocat semblait accorder que l'accusé était Jean\r
+Valjean. Il en prit acte. Cet homme était donc Jean Valjean. Ceci était\r
+acquis à l'accusation et ne pouvait plus se contester. Ici, par une\r
+habile antonomase, remontant aux sources et aux causes de la\r
+criminalité, l'avocat général tonna contre l'immoralité de l'école\r
+romantique, alors à son aurore sous le nom d'école satanique que lui\r
+avaient décerné les critiques de l'Oriflamme et de la Quotidienne, il\r
+attribua, non sans vraisemblance, à l'influence de cette littérature\r
+perverse le délit de Champmathieu, ou pour mieux dire, de Jean Valjean.\r
+Ces considérations épuisées, il passa à Jean Valjean lui-même.\r
+Qu'était-ce que Jean Valjean? Description de Jean Valjean. Un monstre\r
+vomi, etc. Le modèle de ces sortes de descriptions est dans le récit de\r
+Théramène, lequel n'est pas utile à la tragédie, mais rend tous les\r
+jours de grands services à l'éloquence judiciaire. L'auditoire et les\r
+jurés «frémirent». La description achevée, l'avocat général reprit, dans\r
+un mouvement oratoire fait pour exciter au plus haut point le lendemain\r
+matin l'enthousiasme du Journal de la Préfecture:\r
+\r
+Et c'est un pareil homme, etc., etc., etc., vagabond, mendiant, sans\r
+moyens d'existence, etc., etc.,--accoutumé par sa vie passée aux actions\r
+coupables et peu corrigé par son séjour au bagne, comme le prouve le\r
+crime commis sur Petit-Gervais, etc., etc.,--c'est un homme pareil qui,\r
+trouvé sur la voie publique en flagrant délit de vol, à quelques pas\r
+d'un mur escaladé, tenant encore à la main l'objet volé, nie le flagrant\r
+délit, le vol, l'escalade, nie tout, nie jusqu'à son nom, nie jusqu'à\r
+son identité! Outre cent autres preuves sur lesquelles nous ne revenons\r
+pas, quatre témoins le reconnaissent, Javert, l'intègre inspecteur de\r
+police Javert, et trois de ses anciens compagnons d'ignominie, les\r
+forçats Brevet, Chenildieu et Cochepaille. Qu'oppose-t-il à cette\r
+unanimité foudroyante? Il nie. Quel endurcissement! Vous ferez justice,\r
+messieurs les jurés, etc., etc.\r
+\r
+Pendant que l'avocat général parlait, l'accusé écoutait, la bouche\r
+ouverte, avec une sorte d'étonnement où il entrait bien quelque\r
+admiration. Il était évidemment surpris qu'un homme pût parler comme\r
+cela. De temps en temps, aux moments les plus «énergiques» du\r
+réquisitoire, dans ces instants où l'éloquence, qui ne peut se contenir,\r
+déborde dans un flux d'épithètes flétrissantes et enveloppe l'accusé\r
+comme un orage, il remuait lentement la tête de droite à gauche et de\r
+gauche à droite, sorte de protestation triste et muette dont il se\r
+contentait depuis le commencement des débats. Deux ou trois fois les\r
+spectateurs placés le plus près de lui l'entendirent dire à demi-voix:\r
+\r
+--Voilà ce que c'est, de n'avoir pas demandé à M. Baloup!\r
+\r
+L'avocat général fit remarquer au jury cette attitude hébétée, calculée\r
+évidemment, qui dénotait, non l'imbécillité, mais l'adresse, la ruse,\r
+l'habitude de tromper la justice, et qui mettait dans tout son jour «la\r
+profonde perversité» de cet homme. Il termina en faisant ses réserves\r
+pour l'affaire Petit-Gervais, et en réclamant une condamnation sévère.\r
+\r
+C'était, pour l'instant, on s'en souvient, les travaux forcés à\r
+perpétuité.\r
+\r
+Le défenseur se leva, commença par complimenter «monsieur l'avocat\r
+général» sur son «admirable parole», puis répliqua comme il put, mais il\r
+faiblissait; le terrain évidemment se dérobait sous lui.\r
+\r
+\r
+\r
+\r
+Chapitre X\r
+\r
+Le système de dénégations\r
+\r
+\r
+L'instant de clore les débats était venu. Le président fit lever\r
+l'accusé et lui adressa la question d'usage:\r
+\r
+--Avez-vous quelque chose à ajouter à votre défense?\r
+\r
+L'homme, debout, roulant dans ses mains un affreux bonnet qu'il avait,\r
+sembla ne pas entendre.\r
+\r
+Le président répéta la question.\r
+\r
+Cette fois l'homme entendit. Il parut comprendre, il fit le mouvement de\r
+quelqu'un qui se réveille, promena ses yeux autour de lui, regarda le\r
+public, les gendarmes, son avocat, les jurés, la cour, posa son poing\r
+monstrueux sur le rebord de la boiserie placée devant son banc, regarda\r
+encore, et tout à coup, fixant sont regard sur l'avocat général, il se\r
+mit à parler. Ce fut comme une éruption. Il sembla, à la façon dont les\r
+paroles s'échappaient de sa bouche, incohérentes, impétueuses, heurtées,\r
+pêle-mêle, qu'elles s'y pressaient toutes à la fois pour sortir en même\r
+temps. Il dit:\r
+\r
+--J'ai à dire ça. Que j'ai été charron à Paris, même que c'était chez\r
+monsieur Baloup. C'est un état dur. Dans la chose de charron, on\r
+travaille toujours en plein air, dans des cours, sous des hangars chez\r
+les bons maîtres, jamais dans des ateliers fermés, parce qu'il faut des\r
+espaces, voyez-vous. L'hiver, on a si froid qu'on se bat les bras pour\r
+se réchauffer; mais les maîtres ne veulent pas, ils disent que cela perd\r
+du temps. Manier du fer quand il y a de la glace entre les pavés, c'est\r
+rude. Ça vous use vite un homme. On est vieux tout jeune dans cet\r
+état-là. À quarante ans, un homme est fini. Moi, j'en avais\r
+cinquante-trois, j'avais bien du mal. Et puis c'est si méchant les\r
+ouvriers! Quand un bonhomme n'est plus jeune, on vous l'appelle pour\r
+tout vieux serin, vieille bête! Je ne gagnais plus que trente sous par\r
+jour, on me payait le moins cher qu'on pouvait, les maîtres profitaient\r
+de mon âge. Avec ça, j'avais ma fille qui était blanchisseuse à la\r
+rivière. Elle gagnait un peu de son côté. À nous deux, cela allait. Elle\r
+avait de la peine aussi. Toute la journée dans un baquet jusqu'à\r
+mi-corps, à la pluie, à la neige, avec le vent qui vous coupe la figure;\r
+quand il gèle, c'est tout de même, il faut laver; il y a des personnes\r
+qui n'ont pas beaucoup de linge et qui attendent après; si on ne lavait\r
+pas, on perdrait des pratiques. Les planches sont mal jointes et il vous\r
+tombe des gouttes d'eau partout. On a ses jupes toutes mouillées, dessus\r
+et dessous. Ça pénètre. Elle a aussi travaillé au lavoir des\r
+Enfants-Rouges, où l'eau arrive par des robinets. On n'est pas dans le\r
+baquet. On lave devant soi au robinet et on rince derrière soi dans le\r
+bassin. Comme c'est fermé, on a moins froid au corps. Mais il y a une\r
+buée d'eau chaude qui est terrible et qui vous perd les yeux. Elle\r
+revenait à sept heures du soir, et se couchait bien vite; elle était si\r
+fatiguée. Son mari la battait. Elle est morte. Nous n'avons pas été bien\r
+heureux. C'était une brave fille qui n'allait pas au bal, qui était bien\r
+tranquille. Je me rappelle un mardi gras où elle était couchée à huit\r
+heures. Voilà. Je dis vrai. Vous n'avez qu'à demander. Ah, bien oui,\r
+demander! que je suis bête! Paris, c'est un gouffre. Qui est-ce qui\r
+connaît le père Champmathieu? Pourtant je vous dis monsieur Baloup.\r
+Voyez chez monsieur Baloup. Après ça, je ne sais pas ce qu'on me veut.\r
+\r
+L'homme se tut, et resta debout. Il avait dit ces choses d'une voix\r
+haute, rapide, rauque, dure et enrouée, avec une sorte de naïveté\r
+irritée et sauvage. Une fois il s'était interrompu pour saluer quelqu'un\r
+dans la foule. Les espèces d'affirmations qu'il semblait jeter au hasard\r
+devant lui, lui venaient comme des hoquets, et il ajoutait à chacune\r
+d'elles le geste d'un bûcheron qui fend du bois. Quand il eut fini,\r
+l'auditoire éclata de rire. Il regarda le public, et voyant qu'on riait,\r
+et ne comprenant pas, il se mit à rire lui-même.\r
+\r
+Cela était sinistre.\r
+\r
+Le président, homme attentif et bienveillant, éleva la voix.\r
+\r
+Il rappela à «messieurs les jurés» que «le sieur Baloup, l'ancien maître\r
+charron chez lequel l'accusé disait avoir servi, avait été inutilement\r
+cité. Il était en faillite, et n'avait pu être retrouvé.» Puis se\r
+tournant vers l'accusé, il l'engagea à écouter ce qu'il allait lui dire\r
+et ajouta:\r
+\r
+--Vous êtes dans une situation où il faut réfléchir. Les présomptions\r
+les plus graves pèsent sur vous et peuvent entraîner des conséquences\r
+capitales. Accusé, dans votre intérêt, je vous interpelle une dernière\r
+fois, expliquez-vous clairement sur ces deux faits:--Premièrement,\r
+avez-vous, oui ou non, franchi le mur du clos Pierron, cassé la branche\r
+et volé les pommes, c'est-à-dire commis le crime de vol avec escalade?\r
+Deuxièmement, oui ou non, êtes-vous le forçat libéré Jean Valjean?\r
+\r
+L'accusé secoua la tête d'un air capable, comme un homme qui a bien\r
+compris et qui sait ce qu'il va répondre. Il ouvrit la bouche, se tourna\r
+vers le président et dit:\r
+\r
+--D'abord....\r
+\r
+Puis il regarda son bonnet, il regarda le plafond, et se tut.\r
+\r
+--Accusé, reprit l'avocat général d'une voix sévère, faites attention.\r
+Vous ne répondez à rien de ce qu'on vous demande. Votre trouble vous\r
+condamne. Il est évident que vous ne vous appelez pas Champmathieu, que\r
+vous êtes le forçat Jean Valjean caché d'abord sous le nom de Jean\r
+Mathieu qui était le nom de sa mère, que vous êtes allé en Auvergne, que\r
+vous êtes né à Faverolles où vous avez été émondeur. Il est évident que\r
+vous avez volé avec escalade des pommes mûres dans le clos Pierron.\r
+Messieurs les jurés apprécieront.\r
+\r
+L'accusé avait fini par se rasseoir; il se leva brusquement quand\r
+l'avocat général eut fini, et s'écria:\r
+\r
+--Vous êtes très méchant, vous! Voilà ce que je voulais dire. Je ne\r
+trouvais pas d'abord. Je n'ai rien volé. Je suis un homme qui ne mange\r
+pas tous les jours. Je venais d'Ailly, je marchais dans le pays après\r
+une ondée qui avait fait la campagne toute jaune, même que les mares\r
+débordaient et qu'il ne sortait plus des sables que de petits brins\r
+d'herbe au bord de la route, j'ai trouvé une branche cassée par terre où\r
+il y avait des pommes, j'ai ramassé la branche sans savoir qu'elle me\r
+ferait arriver de la peine. Il y a trois mois que je suis en prison et\r
+qu'on me trimballe. Après ça, je ne peux pas dire, on parle contre moi,\r
+on me dit: répondez! le gendarme, qui est bon enfant, me pousse le coude\r
+et me dit tout bas: réponds donc. Je ne sais pas expliquer, moi, je n'ai\r
+pas fait les études, je suis un pauvre homme. Voilà ce qu'on a tort de\r
+ne pas voir. Je n'ai pas volé, j'ai ramassé par terre des choses qu'il y\r
+avait. Vous dites Jean Valjean, Jean Mathieu! Je ne connais pas ces\r
+personnes-là. C'est des villageois. J'ai travaillé chez monsieur Baloup,\r
+boulevard de l'Hôpital. Je m'appelle Champmathieu. Vous êtes bien malins\r
+de me dire où je suis né. Moi, je l'ignore. Tout le monde n'a pas des\r
+maisons pour y venir au monde. Ce serait trop commode. Je crois que mon\r
+père et ma mère étaient des gens qui allaient sur les routes. Je ne sais\r
+pas d'ailleurs. Quand j'étais enfant, on m'appelait Petit, maintenant,\r
+on m'appelle Vieux. Voilà mes noms de baptême. Prenez ça comme vous\r
+voudrez. J'ai été en Auvergne, j'ai été à Faverolles, pardi! Eh bien?\r
+est-ce qu'on ne peut pas avoir été en Auvergne et avoir été à Faverolles\r
+sans avoir été aux galères? Je vous dis que je n'ai pas volé, et que je\r
+suis le père Champmathieu. J'ai été chez monsieur Baloup, j'ai été\r
+domicilié. Vous m'ennuyez avec vos bêtises à la fin! Pourquoi donc\r
+est-ce que le monde est après moi comme des acharnés!\r
+\r
+L'avocat général était demeuré debout; il s'adressa au président:\r
+\r
+--Monsieur le président, en présence des dénégations confuses, mais fort\r
+habiles de l'accusé, qui voudrait bien se faire passer pour idiot, mais\r
+qui n'y parviendra pas--nous l'en prévenons--nous requérons qu'il vous\r
+plaise et qu'il plaise à la cour appeler de nouveau dans cette enceinte\r
+les condamnés Brevet, Cochepaille et Chenildieu et l'inspecteur de\r
+police Javert, et les interpeller une dernière fois sur l'identité de\r
+l'accusé avec le forçat Jean Valjean.\r
+\r
+--Je fais remarquer à monsieur l'avocat général, dit le président, que\r
+l'inspecteur de police Javert, rappelé par ses fonctions au chef-lieu\r
+d'un arrondissement voisin, a quitté l'audience et même la ville,\r
+aussitôt sa déposition faite. Nous lui en avons accordé l'autorisation,\r
+avec l'agrément de monsieur l'avocat général et du défenseur de\r
+l'accusé.\r
+\r
+--C'est juste, monsieur le président, reprit l'avocat général. En\r
+l'absence du sieur Javert, je crois devoir rappeler à messieurs les\r
+jurés ce qu'il a dit ici-même, il y a peu d'heures. Javert est un homme\r
+estimé qui honore par sa rigoureuse et stricte probité des fonctions\r
+inférieures, mais importantes. Voici en quels termes il a déposé:--«Je\r
+n'ai pas même besoin des présomptions morales et des preuves matérielles\r
+qui démentent les dénégations de l'accusé. Je le reconnais parfaitement.\r
+Cet homme ne s'appelle pas Champmathieu; c'est un ancien forçat très\r
+méchant et très redouté nommé Jean Valjean. On ne l'a libéré à\r
+l'expiration de sa peine qu'avec un extrême regret. Il a subi dix-neuf\r
+ans de travaux forcés pour vol qualifié. Il avait cinq ou six fois tenté\r
+de s'évader. Outre le vol Petit-Gervais et le vol Pierron, je le\r
+soupçonne encore d'un vol commis chez sa grandeur le défunt évêque de\r
+Digne. Je l'ai souvent vu, à l'époque où j'étais adjudant garde-chiourme\r
+au bagne de Toulon. Je répète que je le reconnais parfaitement.» Cette\r
+déclaration si précise parut produire une vive impression sur le public\r
+et le jury. L'avocat général termina en insistant pour qu'à défaut de\r
+Javert, les trois témoins Brevet, Chenildieu et Cochepaille fussent\r
+entendus de nouveau et interpellés solennellement.\r
+\r
+Le président transmit un ordre à un huissier, et un moment après la\r
+porte de la chambre des témoins s'ouvrit. L'huissier, accompagné d'un\r
+gendarme prêt à lui prêter main-forte, introduisit le condamné Brevet.\r
+L'auditoire était en suspens et toutes les poitrines palpitaient comme\r
+si elles n'eussent eu qu'une seule âme.\r
+\r
+L'ancien forçat Brevet portait la veste noire et grise des maisons\r
+centrales. Brevet était un personnage d'une soixantaine d'années qui\r
+avait une espèce de figure d'homme d'affaires et l'air d'un coquin. Cela\r
+va quelquefois ensemble. Il était devenu, dans la prison où de nouveaux\r
+méfaits l'avaient ramené, quelque chose comme guichetier. C'était un\r
+homme dont les chefs disaient: Il cherche à se rendre utile. Les\r
+aumôniers portaient bon témoignage de ses habitudes religieuses. Il ne\r
+faut pas oublier que ceci se passait sous la restauration.\r
+\r
+--Brevet, dit le président, vous avez subi une condamnation infamante et\r
+vous ne pouvez prêter serment....\r
+\r
+Brevet baissa les yeux.\r
+\r
+--Cependant, reprit le président, même dans l'homme que la loi a\r
+dégradé, il peut rester, quand la pitié divine le permet, un sentiment\r
+d'honneur et d'équité. C'est à ce sentiment que je fais appel à cette\r
+heure décisive. S'il existe encore en vous, et je l'espère, réfléchissez\r
+avant de me répondre, considérez d'une part cet homme qu'un mot de vous\r
+peut perdre, d'autre part la justice qu'un mot de vous peut éclairer.\r
+L'instant est solennel, et il est toujours temps de vous rétracter, si\r
+vous croyez vous être trompé.--Accusé, levez-vous.\r
+\r
+--Brevet, regardez bien l'accusé, recueillez vos souvenirs, et\r
+dites-nous, en votre âme et conscience, si vous persistez à reconnaître\r
+cet homme pour votre ancien camarade de bagne Jean Valjean.\r
+\r
+Brevet regarda l'accusé, puis se retourna vers la cour.\r
+\r
+--Oui, monsieur le président. C'est moi qui l'ai reconnu le premier et\r
+je persiste. Cet homme est Jean Valjean. Entré à Toulon en 1796 et sorti\r
+en 1815. Je suis sorti l'an d'après. Il a l'air d'une brute maintenant,\r
+alors ce serait que l'âge l'a abruti; au bagne il était sournois. Je le\r
+reconnais positivement.\r
+\r
+--Allez vous asseoir, dit le président. Accusé, restez debout.\r
+\r
+On introduisit Chenildieu, forçat à vie, comme l'indiquaient sa casaque\r
+rouge et son bonnet vert. Il subissait sa peine au bagne de Toulon, d'où\r
+on l'avait extrait pour cette affaire. C'était un petit homme d'environ\r
+cinquante ans, vif, ridé, chétif, jaune, effronté, fiévreux, qui avait\r
+dans tous ses membres et dans toute sa personne une sorte de faiblesse\r
+maladive et dans le regard une force immense. Ses compagnons du bagne\r
+l'avaient surnommé Je-nie-Dieu.\r
+\r
+Le président lui adressa à peu près les mêmes paroles qu'à Brevet. Au\r
+moment où il lui rappela que son infamie lui ôtait le droit de prêter\r
+serment, Chenildieu leva la tête et regarda la foule en face. Le\r
+président l'invita à se recueillir et lui demanda, comme à Brevet, s'il\r
+persistait à reconnaître l'accusé.\r
+\r
+Chenildieu éclata de rire.\r
+\r
+--Pardine! si je le reconnais! nous avons été cinq ans attachés à la\r
+même chaîne. Tu boudes donc, mon vieux?\r
+\r
+--Allez vous asseoir, dit le président.\r
+\r
+L'huissier amena Cochepaille. Cet autre condamné à perpétuité, venu du\r
+bagne et vêtu de rouge comme Chenildieu, était un paysan de Lourdes et\r
+un demi-ours des Pyrénées. Il avait gardé des troupeaux dans la\r
+montagne, et de pâtre il avait glissé brigand. Cochepaille n'était pas\r
+moins sauvage et paraissait plus stupide encore que l'accusé. C'était un\r
+de ces malheureux hommes que la nature a ébauchés en bêtes fauves et que\r
+la société termine en galériens.\r
+\r
+Le président essaya de le remuer par quelques paroles pathétiques et\r
+graves et lui demanda, comme aux deux autres, s'il persistait, sans\r
+hésitation et sans trouble, à reconnaître l'homme debout devant lui.\r
+\r
+--C'est Jean Valjean, dit Cochepaille. Même qu'on l'appelait\r
+Jean-le-Cric, tant il était fort.\r
+\r
+Chacune des affirmations de ces trois hommes, évidemment sincères et de\r
+bonne foi, avait soulevé dans l'auditoire un murmure de fâcheux augure\r
+pour l'accusé, murmure qui croissait et se prolongeait plus longtemps\r
+chaque fois qu'une déclaration nouvelle venait s'ajouter à la\r
+précédente. L'accusé, lui, les avait écoutées avec ce visage étonné qui,\r
+selon l'accusation, était son principal moyen de défense. À la première,\r
+les gendarmes ses voisins l'avaient entendu grommeler entre ses dents:\r
+Ah bien! en voilà un! Après la seconde il dit un peu plus haut, d'un air\r
+presque satisfait: Bon! À la troisième il s'écria: Fameux!\r
+\r
+Le président l'interpella.\r
+\r
+--Accusé, vous avez entendu. Qu'avez-vous à dire?\r
+\r
+Il répondit:\r
+\r
+--Je dis--Fameux!\r
+\r
+Une rumeur éclata dans le public et gagna presque le jury. Il était\r
+évident que l'homme était perdu.\r
+\r
+--Huissiers, dit le président, faites faire silence. Je vais clore les\r
+débats.\r
+\r
+En ce moment un mouvement se fit tout à côté du président. On entendit\r
+une voix qui criait:\r
+\r
+--Brevet, Chenildieu, Cochepaille! regardez de ce côté-ci.\r
+\r
+Tous ceux qui entendirent cette voix se sentirent glacés, tant elle\r
+était lamentable et terrible. Les yeux se tournèrent vers le point d'où\r
+elle venait. Un homme, placé parmi les spectateurs privilégiés qui\r
+étaient assis derrière la cour, venait de se lever, avait poussé la\r
+porte à hauteur d'appui qui séparait le tribunal du prétoire, et était\r
+debout au milieu de la salle. Le président, l'avocat général, M.\r
+Bamatabois, vingt personnes, le reconnurent, et s'écrièrent à la fois:\r
+\r
+--Monsieur Madeleine!\r
+\r
+\r
+\r
+\r
+Chapitre XI\r
+\r
+Champmathieu de plus en plus étonné\r
+\r
+\r
+C'était lui en effet. La lampe du greffier éclairait son visage. Il\r
+tenait son chapeau à la main, il n'y avait aucun désordre dans ses\r
+vêtements, sa redingote était boutonnée avec soin. Il était très pâle et\r
+il tremblait légèrement. Ses cheveux, gris encore au moment de son\r
+arrivée à Arras, étaient maintenant tout à fait blancs. Ils avaient\r
+blanchi depuis une heure qu'il était là.\r
+\r
+Toutes les têtes se dressèrent. La sensation fut indescriptible. Il y\r
+eut dans l'auditoire un instant d'hésitation. La voix avait été si\r
+poignante, l'homme qui était là paraissait si calme, qu'au premier abord\r
+on ne comprit pas. On se demanda qui avait crié. On ne pouvait croire\r
+que ce fût cet homme tranquille qui eût jeté ce cri effrayant.\r
+\r
+Cette indécision ne dura que quelques secondes. Avant même que le\r
+président et l'avocat général eussent pu dire un mot, avant que les\r
+gendarmes et les huissiers eussent pu faire un geste, l'homme que tous\r
+appelaient encore en ce moment M. Madeleine s'était avancé vers les\r
+témoins Cochepaille, Brevet et Chenildieu.\r
+\r
+--Vous ne me reconnaissez pas? dit-il.\r
+\r
+Tous trois demeurèrent interdits et indiquèrent par un signe de tête\r
+qu'ils ne le connaissaient point. Cochepaille intimidé fit le salut\r
+militaire. M. Madeleine se tourna vers les jurés et vers la cour et dit\r
+d'une voix douce:\r
+\r
+--Messieurs les jurés, faites relâcher l'accusé. Monsieur le président,\r
+faites-moi arrêter. L'homme que vous cherchez, ce n'est pas lui, c'est\r
+moi. Je suis Jean Valjean. Pas une bouche ne respirait. À la première\r
+commotion de l'étonnement avait succédé un silence de sépulcre. On\r
+sentait dans la salle cette espèce de terreur religieuse qui saisit la\r
+foule lorsque quelque chose de grand s'accomplit.\r
+\r
+Cependant le visage du président s'était empreint de sympathie et de\r
+tristesse; il avait échangé un signe rapide avec l'avocat et quelques\r
+paroles à voix basse avec les conseillers assesseurs. Il s'adressa au\r
+public, et demanda avec un accent qui fut compris de tous:\r
+\r
+--Y a-t-il un médecin ici?\r
+\r
+L'avocat général prit la parole:\r
+\r
+--Messieurs les jurés, l'incident si étrange et si inattendu qui trouble\r
+l'audience ne nous inspire, ainsi qu'à vous, qu'un sentiment que nous\r
+n'avons pas besoin d'exprimer. Vous connaissez tous, au moins de\r
+réputation, l'honorable M. Madeleine, maire de Montreuil-sur-mer. S'il y\r
+a un médecin dans l'auditoire, nous nous joignons à monsieur le\r
+président pour le prier de vouloir bien assister monsieur Madeleine et\r
+le reconduire à sa demeure.\r
+\r
+M. Madeleine ne laissa point achever l'avocat général.\r
+\r
+Il l'interrompit d'un accent plein de mansuétude et d'autorité. Voici\r
+les paroles qu'il prononça; les voici littéralement, telles qu'elles\r
+furent écrites immédiatement après l'audience par un des témoins de\r
+cette scène; telles qu'elles sont encore dans l'oreille de ceux qui les\r
+ont entendues, il y a près de quarante ans aujourd'hui.\r
+\r
+--Je vous remercie, monsieur l'avocat général, mais je ne suis pas fou.\r
+Vous allez voir. Vous étiez sur le point de commettre une grande erreur,\r
+lâchez cet homme, j'accomplis un devoir, je suis ce malheureux condamné.\r
+Je suis le seul qui voie clair ici, et je vous dis la vérité. Ce que je\r
+fais en ce moment, Dieu, qui est là-haut, le regarde, et cela suffit.\r
+Vous pouvez me prendre, puisque me voilà. J'avais pourtant fait de mon\r
+mieux. Je me suis caché sous un nom; je suis devenu riche, je suis\r
+devenu maire; j'ai voulu rentrer parmi les honnêtes gens. Il paraît que\r
+cela ne se peut pas. Enfin, il y a bien des choses que je ne puis pas\r
+dire, je ne vais pas vous raconter ma vie, un jour on saura. J'ai volé\r
+monseigneur l'évêque, cela est vrai; j'ai volé Petit-Gervais, cela est\r
+vrai. On a eu raison de vous dire que Jean Valjean était un malheureux\r
+très méchant. Toute la faute n'est peut-être pas à lui. Écoutez,\r
+messieurs les juges, un homme aussi abaissé que moi n'a pas de\r
+remontrance à faire à la providence ni de conseil à donner à la société;\r
+mais, voyez-vous, l'infamie d'où j'avais essayé de sortir est une chose\r
+nuisible. Les galères font le galérien. Recueillez cela, si vous voulez.\r
+\r
+Avant le bagne, j'étais un pauvre paysan très peu intelligent, une\r
+espèce d'idiot; le bagne m'a changé. J'étais stupide, je suis devenu\r
+méchant; j'étais bûche, je suis devenu tison. Plus tard l'indulgence et\r
+la bonté m'ont sauvé, comme la sévérité m'avait perdu. Mais, pardon,\r
+vous ne pouvez pas comprendre ce que je dis là. Vous trouverez chez moi,\r
+dans les cendres de la cheminée, la pièce de quarante sous que j'ai\r
+volée il y a sept ans à Petit-Gervais. Je n'ai plus rien à ajouter.\r
+Prenez-moi. Mon Dieu! monsieur l'avocat général remue la tête, vous\r
+dites: M. Madeleine est devenu fou, vous ne me croyez pas! Voilà qui est\r
+affligeant. N'allez point condamner cet homme au moins! Quoi! ceux-ci ne\r
+me reconnaissent pas! Je voudrais que Javert fût ici. Il me\r
+reconnaîtrait, lui!\r
+\r
+Rien ne pourrait rendre ce qu'il y avait de mélancolie bienveillante et\r
+sombre dans l'accent qui accompagnait ces paroles.\r
+\r
+Il se tourna vers les trois forçats:\r
+\r
+--Eh bien, je vous reconnais, moi! Brevet! vous rappelez-vous?...\r
+\r
+Il s'interrompit, hésita un moment, et dit:\r
+\r
+--Te rappelles-tu ces bretelles en tricot à damier que tu avais au\r
+bagne?\r
+\r
+Brevet eut comme une secousse de surprise et le regarda de la tête aux\r
+pieds d'un air effrayé. Lui continua:\r
+\r
+--Chenildieu, qui te surnommais toi-même Je-nie-Dieu, tu as toute\r
+l'épaule droite brûlée profondément, parce que tu t'es couché un jour\r
+l'épaule sur un réchaud plein de braise, pour effacer les trois lettres\r
+T. F. P., qu'on y voit toujours cependant. Réponds, est-ce vrai?\r
+\r
+--C'est vrai, dit Chenildieu.\r
+\r
+Il s'adressa à Cochepaille:\r
+\r
+--Cochepaille, tu as près de la saignée du bras gauche une date gravée\r
+en lettres bleues avec de la poudre brûlée. Cette date, c'est celle du\r
+débarquement de l'empereur à Cannes, _1er mars 1815_. Relève ta manche.\r
+\r
+Cochepaille releva sa manche, tous les regards se penchèrent autour de\r
+lui sur son bras nu. Un gendarme approcha une lampe; la date y était.\r
+\r
+Le malheureux homme se tourna vers l'auditoire et vers les juges avec un\r
+sourire dont ceux qui l'ont vu sont encore navrés lorsqu'ils y songent.\r
+C'était le sourire du triomphe, c'était aussi le sourire du désespoir.\r
+\r
+--Vous voyez bien, dit-il, que je suis Jean Valjean.\r
+\r
+Il n'y avait plus dans cette enceinte ni juges, ni accusateurs, ni\r
+gendarmes; il n'y avait que des yeux fixes et des coeurs émus. Personne\r
+ne se rappelait plus le rôle que chacun pouvait avoir à jouer; l'avocat\r
+général oubliait qu'il était là pour requérir, le président qu'il était\r
+là pour présider, le défenseur qu'il était là pour défendre. Chose\r
+frappante, aucune question ne fut faite, aucune autorité n'intervint. Le\r
+propre des spectacles sublimes, c'est de prendre toutes les âmes et de\r
+faire de tous les témoins des spectateurs. Aucun peut-être ne se rendait\r
+compte de ce qu'il éprouvait; aucun, sans doute, ne se disait qu'il\r
+voyait resplendir là une grande lumière; tous intérieurement se\r
+sentaient éblouis.\r
+\r
+Il était évident qu'on avait sous les yeux Jean Valjean. Cela rayonnait.\r
+L'apparition de cet homme avait suffi pour remplir de clarté cette\r
+aventure si obscure le moment d'auparavant. Sans qu'il fût besoin\r
+d'aucune explication désormais, toute cette foule, comme par une sorte\r
+de révélation électrique, comprit tout de suite et d'un seul coup d'oeil\r
+cette simple et magnifique histoire d'un homme qui se livrait pour qu'un\r
+autre homme ne fût pas condamné à sa place. Les détails, les\r
+hésitations, les petites résistances possibles se perdirent dans ce\r
+vaste fait lumineux.\r
+\r
+Impression qui passa vite, mais qui dans l'instant fut irrésistible.\r
+\r
+--Je ne veux pas déranger davantage l'audience, reprit Jean Valjean. Je\r
+m'en vais, puisqu'on ne m'arrête pas. J'ai plusieurs choses à faire.\r
+Monsieur l'avocat général sait qui je suis, il sait où je vais, il me\r
+fera arrêter quand il voudra.\r
+\r
+Il se dirigea vers la porte de sortie. Pas une voix ne s'éleva, pas un\r
+bras ne s'étendit pour l'empêcher. Tous s'écartèrent. Il avait en ce\r
+moment ce je ne sais quoi de divin qui fait que les multitudes reculent\r
+et se rangent devant un homme. Il traversa la foule à pas lents. On n'a\r
+jamais su qui ouvrit la porte, mais il est certain que la porte se\r
+trouva ouverte lorsqu'il y parvint. Arrivé là, il se retourna et dit:\r
+\r
+--Monsieur l'avocat général, je reste à votre disposition.\r
+\r
+Puis il s'adressa à l'auditoire:\r
+\r
+--Vous tous, tous ceux qui sont ici, vous me trouvez digne de pitié,\r
+n'est-ce pas? Mon Dieu! quand je pense à ce que j'ai été sur le point de\r
+faire, je me trouve digne d'envie. Cependant j'aurais mieux aimé que\r
+tout ceci n'arrivât pas.\r
+\r
+Il sortit, et la porte se referma comme elle avait été ouverte, car ceux\r
+qui font de certaines choses souveraines sont toujours sûrs d'être\r
+servis par quelqu'un dans la foule.\r
+\r
+Moins d'une heure après, le verdict du jury déchargeait de toute\r
+accusation le nommé Champmathieu; et Champmathieu, mis en liberté\r
+immédiatement, s'en allait stupéfait, croyant tous les hommes fous et ne\r
+comprenant rien à cette vision.\r

+\r
+Livre huitième--Contre-coup\r
+\r
+\r
+\r
+\r
+Chapitre I\r
+\r
+Dans quel miroir M. Madeleine regarde ses cheveux\r
+\r
+\r
+Le jour commençait à poindre. Fantine avait eu une nuit de fièvre et\r
+d'insomnie, pleine d'ailleurs d'images heureuses; au matin, elle\r
+s'endormit. La soeur Simplice qui l'avait veillée profita de ce sommeil\r
+pour aller préparer une nouvelle potion de quinquina. La digne soeur\r
+était depuis quelques instants dans le laboratoire de l'infirmerie,\r
+penchée sur ses drogues et sur ses fioles et regardant de très près à\r
+cause de cette brume que le crépuscule répand sur les objets. Tout à\r
+coup elle tourna la tête et fit un léger cri. M. Madeleine était devant\r
+elle. Il venait d'entrer silencieusement.\r
+\r
+--C'est vous, monsieur le maire! s'écria-t-elle.\r
+\r
+Il répondit, à voix basse:\r
+\r
+--Comment va cette pauvre femme?\r
+\r
+--Pas mal en ce moment. Mais nous avons été bien inquiets, allez!\r
+\r
+Elle lui expliqua ce qui s'était passé, que Fantine était bien mal la\r
+veille et que maintenant elle était mieux, parce qu'elle croyait que\r
+monsieur le maire était allé chercher son enfant à Montfermeil. La soeur\r
+n'osa pas interroger monsieur le maire, mais elle vit bien à son air que\r
+ce n'était point de là qu'il venait.\r
+\r
+--Tout cela est bien, dit-il, vous avez eu raison de ne pas la\r
+détromper.\r
+\r
+--Oui, reprit la soeur, mais maintenant, monsieur le maire, qu'elle va\r
+vous voir et qu'elle ne verra pas son enfant, que lui dirons-nous?\r
+\r
+Il resta un moment rêveur.\r
+\r
+--Dieu nous inspirera, dit-il.\r
+\r
+--On ne pourrait cependant pas mentir, murmura la soeur à demi-voix.\r
+\r
+Le plein jour s'était fait dans la chambre. Il éclairait en face le\r
+visage de M. Madeleine. Le hasard fit que la soeur leva les yeux.\r
+\r
+--Mon Dieu, monsieur! s'écria-t-elle, que vous est-il donc arrivé? vos\r
+cheveux sont tout blancs!\r
+\r
+--Blancs! dit-il.\r
+\r
+La soeur Simplice n'avait point de miroir; elle fouilla dans une trousse\r
+et en tira une petite glace dont se servait le médecin de l'infirmerie\r
+pour constater qu'un malade était mort et ne respirait plus. M.\r
+Madeleine prit la glace, y considéra ses cheveux, et dit:\r
+\r
+--Tiens!\r
+\r
+Il prononça ce mot avec indifférence et comme s'il pensait à autre\r
+chose.\r
+\r
+La soeur se sentit glacée par je ne sais quoi d'inconnu qu'elle\r
+entrevoyait dans tout ceci.\r
+\r
+Il demanda:\r
+\r
+--Puis-je la voir?\r
+\r
+--Est-ce que monsieur le maire ne lui fera pas revenir son enfant? dit\r
+la soeur, osant à peine hasarder une question.\r
+\r
+--Sans doute, mais il faut au moins deux ou trois jours.\r
+\r
+--Si elle ne voyait pas monsieur le maire d'ici là, reprit timidement la\r
+soeur, elle ne saurait pas que monsieur le maire est de retour, il\r
+serait aisé de lui faire prendre patience, et quand l'enfant arriverait\r
+elle penserait tout naturellement que monsieur le maire est arrivé avec\r
+l'enfant. On n'aurait pas de mensonge à faire.\r
+\r
+M. Madeleine parut réfléchir quelques instants, puis il dit avec sa\r
+gravité calme:\r
+\r
+--Non, ma soeur, il faut que je la voie. Je suis peut-être pressé.\r
+\r
+La religieuse ne sembla pas remarquer ce mot «peut-être», qui donnait un\r
+sens obscur et singulier aux paroles de M. le maire. Elle répondit en\r
+baissant les yeux et la voix respectueusement:\r
+\r
+--En ce cas, elle repose, mais monsieur le maire peut entrer.\r
+\r
+Il fit quelques observations sur une porte qui fermait mal, et dont le\r
+bruit pouvait réveiller la malade, puis il entra dans la chambre de\r
+Fantine, s'approcha du lit et entrouvrit les rideaux. Elle dormait. Son\r
+souffle sortait de sa poitrine avec ce bruit tragique qui est propre à\r
+ces maladies, et qui navre les pauvres mères lorsqu'elles veillent la\r
+nuit près de leur enfant condamné et endormi. Mais cette respiration\r
+pénible troublait à peine une sorte de sérénité ineffable, répandue sur\r
+son visage, qui la transfigurait dans son sommeil. Sa pâleur était\r
+devenue de la blancheur; ses joues étaient vermeilles. Ses longs cils\r
+blonds, la seule beauté qui lui fût restée de sa virginité et de sa\r
+jeunesse, palpitaient tout en demeurant clos et baissés. Toute sa\r
+personne tremblait de je ne sais quel déploiement d'ailes prêtes à\r
+s'entrouvrir et à l'emporter, qu'on sentait frémir, mais qu'on ne voyait\r
+pas. À la voir ainsi, on n'eût jamais pu croire que c'était là une\r
+malade presque désespérée. Elle ressemblait plutôt à ce qui va s'envoler\r
+qu'à ce qui va mourir.\r
+\r
+La branche, lorsqu'une main s'approche pour détacher la fleur,\r
+frissonne, et semble à la fois se dérober et s'offrir. Le corps humain a\r
+quelque chose de ce tressaillement, quand arrive l'instant où les doigts\r
+mystérieux de la mort vont cueillir l'âme.\r
+\r
+M. Madeleine resta quelque temps immobile près de ce lit, regardant tour\r
+à tour la malade et le crucifix, comme il faisait deux mois auparavant,\r
+le jour où il était venu pour la première fois la voir dans cet asile.\r
+Ils étaient encore là tous les deux dans la même attitude, elle dormant,\r
+lui priant; seulement maintenant, depuis ces deux mois écoulés, elle\r
+avait des cheveux gris et lui des cheveux blancs.\r
+\r
+La soeur n'était pas entrée avec lui. Il se tenait près de ce lit,\r
+debout, le doigt sur la bouche, comme s'il y eût eu dans la chambre\r
+quelqu'un à faire taire.\r
+\r
+Elle ouvrit les yeux, le vit, et dit paisiblement, avec un sourire:\r
+\r
+--Et Cosette?\r
+\r
+\r
+\r
+\r
+Chapitre II\r
+\r
+Fantine heureuse\r
+\r
+\r
+Elle n'eut pas un mouvement de surprise, ni un mouvement de joie; elle\r
+était la joie même. Cette simple question: «Et Cosette?» fut faite avec\r
+une foi si profonde, avec tant de certitude, avec une absence si\r
+complète d'inquiétude et de doute, qu'il ne trouva pas une parole. Elle\r
+continua:\r
+\r
+--Je savais que vous étiez là. Je dormais, mais je vous voyais. Il y a\r
+longtemps que je vous vois. Je vous ai suivi des yeux toute la nuit.\r
+Vous étiez dans une gloire et vous aviez autour de vous toutes sortes de\r
+figures célestes.\r
+\r
+Il leva son regard vers le crucifix.\r
+\r
+--Mais, reprit-elle, dites-moi donc où est Cosette? Pourquoi ne l'avoir\r
+pas mise sur mon lit pour le moment où je m'éveillerais?\r
+\r
+Il répondit machinalement quelque chose qu'il n'a jamais pu se rappeler\r
+plus tard.\r
+\r
+Heureusement le médecin, averti, était survenu. Il vint en aide à M.\r
+Madeleine.\r
+\r
+--Mon enfant, dit le médecin, calmez-vous. Votre enfant est là.\r
+\r
+Les yeux de Fantine s'illuminèrent et couvrirent de clarté tout son\r
+visage. Elle joignit les mains avec une expression qui contenait tout ce\r
+que la prière peut avoir à la fois de plus violent et de plus doux.\r
+\r
+--Oh! s'écria-t-elle, apportez-la-moi!\r
+\r
+Touchante illusion de mère! Cosette était toujours pour elle le petit\r
+enfant qu'on apporte.\r
+\r
+--Pas encore, reprit le médecin, pas en ce moment. Vous avez un reste de\r
+fièvre. La vue de votre enfant vous agiterait et vous ferait du mal. Il\r
+faut d'abord vous guérir. Elle l'interrompit impétueusement.\r
+\r
+--Mais je suis guérie! je vous dis que je suis guérie! Est-il âne, ce\r
+médecin! Ah çà! je veux voir mon enfant, moi!\r
+\r
+--Vous voyez, dit le médecin, comme vous vous emportez. Tant que vous\r
+serez ainsi, je m'opposerai à ce que vous ayez votre enfant. Il ne\r
+suffit pas de la voir, il faut vivre pour elle. Quand vous serez\r
+raisonnable, je vous l'amènerai moi-même.\r
+\r
+La pauvre mère courba la tête.\r
+\r
+--Monsieur le médecin, je vous demande pardon, je vous demande vraiment\r
+bien pardon. Autrefois, je n'aurais pas parlé comme je viens de faire,\r
+il m'est arrivé tant de malheurs que quelquefois je ne sais plus ce que\r
+je dis. Je comprends, vous craignez l'émotion, j'attendrai tant que vous\r
+voudrez, mais je vous jure que cela ne m'aurait pas fait de mal de voir\r
+ma fille. Je la vois, je ne la quitte pas des yeux depuis hier au soir.\r
+Savez-vous? on me l'apporterait maintenant que je me mettrais à lui\r
+parler doucement. Voilà tout. Est-ce que ce n'est pas bien naturel que\r
+j'aie envie de voir mon enfant qu'on a été me chercher exprès à\r
+Montfermeil? Je ne suis pas en colère. Je sais bien que je vais être\r
+heureuse. Toute la nuit j'ai vu des choses blanches et des personnes qui\r
+me souriaient. Quand monsieur le médecin voudra, il m'apportera ma\r
+Cosette. Je n'ai plus de fièvre, puisque je suis guérie; je sens bien\r
+que je n'ai plus rien du tout; mais je vais faire comme si j'étais\r
+malade et ne pas bouger pour faire plaisir aux dames d'ici. Quand on\r
+verra que je suis bien tranquille, on dira: il faut lui donner son\r
+enfant.\r
+\r
+M. Madeleine s'était assis sur une chaise qui était à côté du lit. Elle\r
+se tourna vers lui; elle faisait visiblement effort pour paraître calme\r
+et «bien sage», comme elle disait dans cet affaiblissement de la maladie\r
+qui ressemble à l'enfance, afin que, la voyant si paisible, on ne fît\r
+pas difficulté de lui amener Cosette. Cependant, tout en se contenant,\r
+elle ne pouvait s'empêcher d'adresser à M. Madeleine mille questions.\r
+\r
+--Avez-vous fait un bon voyage, monsieur le maire? Oh! comme vous êtes\r
+bon d'avoir été me la chercher! Dites-moi seulement comment elle est.\r
+A-t-elle bien supporté la route? Hélas! elle ne me reconnaîtra pas!\r
+Depuis le temps, elle m'a oubliée, pauvre chou! Les enfants, cela n'a\r
+pas de mémoire. C'est comme des oiseaux. Aujourd'hui cela voit une chose\r
+et demain une autre, et cela ne pense plus à rien. Avait-elle du linge\r
+blanc seulement? Ces Thénardier la tenaient-ils proprement? Comment la\r
+nourrissait-on? Oh! comme j'ai souffert, si vous saviez! de me faire\r
+toutes ces questions-là dans le temps de ma misère! Maintenant, c'est\r
+passé. Je suis joyeuse. Oh! que je voudrais donc la voir! Monsieur le\r
+maire, l'avez-vous trouvée jolie? N'est-ce pas qu'elle est belle, ma\r
+fille? Vous devez avoir eu bien froid dans cette diligence! Est-ce qu'on\r
+ne pourrait pas l'amener rien qu'un petit moment? On la remporterait\r
+tout de suite après. Dites! vous qui êtes le maître, si vous vouliez!\r
+\r
+Il lui prit la main:\r
+\r
+--Cosette est belle, dit-il, Cosette se porte bien, vous la verrez\r
+bientôt, mais apaisez-vous. Vous parlez trop vivement, et puis vous\r
+sortez vos bras du lit, et cela vous fait tousser.\r
+\r
+En effet, des quintes de toux interrompaient Fantine presque à chaque\r
+mot.\r
+\r
+Fantine ne murmura pas, elle craignait d'avoir compromis par quelques\r
+plaintes trop passionnées la confiance qu'elle voulait inspirer, et elle\r
+se mit à dire des paroles indifférentes.\r
+\r
+--C'est assez joli, Montfermeil, n'est-ce-pas? L'été, on va y faire des\r
+parties de plaisir. Ces Thénardier font-ils de bonnes affaires? Il ne\r
+passe pas grand monde dans leur pays. C'est une espèce de gargote que\r
+cette auberge-là.\r
+\r
+M. Madeleine lui tenait toujours la main, il la considérait avec\r
+anxiété; il était évident qu'il était venu pour lui dire des choses\r
+devant lesquelles sa pensée hésitait maintenant. Le médecin, sa visite\r
+faite, s'était retiré. La soeur Simplice était seule restée auprès\r
+d'eux.\r
+\r
+Cependant, au milieu de ce silence, Fantine s'écria:\r
+\r
+--Je l'entends! mon Dieu! je l'entends!\r
+\r
+Elle étendit le bras pour qu'on se tût autour d'elle, retint son\r
+souffle, et se mit à écouter avec ravissement.\r
+\r
+Il y avait un enfant qui jouait dans la cour; l'enfant de la portière ou\r
+d'une ouvrière quelconque. C'est là un de ces hasards qu'on retrouve\r
+toujours et qui semblent faire partie de la mystérieuse mise en scène\r
+des événements lugubres. L'enfant, c'était une petite fille, allait,\r
+venait, courait pour se réchauffer, riait et chantait à haute voix.\r
+Hélas! à quoi les jeux des enfants ne se mêlent-ils pas! C'était cette\r
+petite fille que Fantine entendait chanter.\r
+\r
+--Oh! reprit-elle, c'est ma Cosette! je reconnais sa voix!\r
+\r
+L'enfant s'éloigna comme il était venu, la voix s'éteignit, Fantine\r
+écouta encore quelque temps, puis son visage s'assombrit, et M.\r
+Madeleine l'entendit qui disait à voix basse:\r
+\r
+--Comme ce médecin est méchant de ne pas me laisser voir ma fille! Il a\r
+une mauvaise figure, cet homme-là!\r
+\r
+Cependant le fond riant de ses idées revint. Elle continua de se parler\r
+à elle-même, la tête sur l'oreiller.\r
+\r
+--Comme nous allons être heureuses! Nous aurons un petit jardin,\r
+d'abord! M. Madeleine me l'a promis. Ma fille jouera dans le jardin.\r
+Elle doit savoir ses lettres maintenant. Je la ferai épeler. Elle courra\r
+dans l'herbe après les papillons. Je la regarderai. Et puis elle fera sa\r
+première communion. Ah çà! quand fera-t-elle sa première communion? Elle\r
+se mit à compter sur ses doigts.\r
+\r
+--... Un, deux, trois, quatre... elle a sept ans. Dans cinq ans. Elle\r
+aura un voile blanc, des bas à jour, elle aura l'air d'une petite femme.\r
+Ô ma bonne soeur, vous ne savez pas comme je suis bête, voilà que je\r
+pense à la première communion de ma fille! Et elle se mit à rire.\r
+\r
+Il avait quitté la main de Fantine. Il écoutait ces paroles comme on\r
+écoute un vent qui souffle, les yeux à terre, l'esprit plongé dans des\r
+réflexions sans fond. Tout à coup elle cessa de parler, cela lui fit\r
+lever machinalement la tête. Fantine était devenue effrayante.\r
+\r
+Elle ne parlait plus, elle ne respirait plus; elle s'était soulevée à\r
+demi sur son séant, son épaule maigre sortait de sa chemise, son visage,\r
+radieux le moment d'auparavant, était blême, et elle paraissait fixer\r
+sur quelque chose de formidable, devant elle, à l'autre extrémité de la\r
+chambre, son oeil agrandi par la terreur.\r
+\r
+--Mon Dieu! s'écria-t-il. Qu'avez-vous, Fantine?\r
+\r
+Elle ne répondit pas, elle ne quitta point des yeux l'objet quelconque\r
+qu'elle semblait voir, elle lui toucha le bras d'une main et de l'autre\r
+lui fit signe de regarder derrière lui.\r
+\r
+Il se retourna, et vit Javert.\r
+\r
+\r
+\r
+\r
+Chapitre III\r
+\r
+Javert content\r
+\r
+\r
+Voici ce qui s'était passé.\r
+\r
+Minuit et demi venait de sonner, quand M. Madeleine était sorti de la\r
+salle des assises d'Arras. Il était rentré à son auberge juste à temps\r
+pour repartir par la malle-poste où l'on se rappelle qu'il avait retenu\r
+sa place. Un peu avant six heures du matin, il était arrivé à\r
+Montreuil-sur-mer, et son premier soin avait été de jeter à la poste sa\r
+lettre à M. Laffitte, puis d'entrer à l'infirmerie et de voir Fantine.\r
+\r
+Cependant, à peine avait-il quitté la salle d'audience de la cour\r
+d'assises, que l'avocat général, revenu du premier saisissement, avait\r
+pris la parole pour déplorer l'acte de folie de l'honorable maire de\r
+Montreuil-sur-mer, déclarer que ses convictions n'étaient en rien\r
+modifiées par cet incident bizarre qui s'éclaircirait plus tard, et\r
+requérir, en attendant, la condamnation de ce Champmathieu, évidemment\r
+le vrai Jean Valjean. La persistance de l'avocat général était\r
+visiblement en contradiction avec le sentiment de tous, du public, de la\r
+cour et du jury. Le défenseur avait eu peu de peine à réfuter cette\r
+harangue et à établir que, par suite des révélations de M. Madeleine,\r
+c'est-à-dire du vrai Jean Valjean, la face de l'affaire était\r
+bouleversée de fond en comble, et que le jury n'avait plus devant les\r
+yeux qu'un innocent. L'avocat avait tiré de là quelques épiphonèmes,\r
+malheureusement peu neufs, sur les erreurs judiciaires, etc., etc., le\r
+président dans son résumé s'était joint au défenseur, et le jury en\r
+quelques minutes avait mis hors de cause Champmathieu.\r
+\r
+Cependant il fallait un Jean Valjean à l'avocat général, et, n'ayant\r
+plus Champmathieu, il prit Madeleine.\r
+\r
+Immédiatement après la mise en liberté de Champmathieu, l'avocat général\r
+s'enferma avec le président. Ils conférèrent «de la nécessité de se\r
+saisir de la personne de M. le maire de Montreuil-sur-mer». Cette\r
+phrase, où il y a beaucoup de _de_, est de M. l'avocat général,\r
+entièrement écrite de sa main sur la minute de son rapport au procureur\r
+général. La première émotion passée, le président fit peu d'objections.\r
+Il fallait bien que justice eût son cours. Et puis, pour tout dire,\r
+quoique le président fût homme bon et assez intelligent, il était en\r
+même temps fort royaliste et presque ardent, et il avait été choqué que\r
+le maire de Montreuil-sur-mer, en parlant du débarquement à Cannes, eût\r
+dit l'_empereur_ et non _Buonaparte_.\r
+\r
+L'ordre d'arrestation fut donc expédié. L'avocat général l'envoya à\r
+Montreuil-sur-mer par un exprès, à franc étrier, et en chargea\r
+l'inspecteur de police Javert.\r
+\r
+On sait que Javert était revenu à Montreuil-sur-mer immédiatement après\r
+avoir fait sa déposition.\r
+\r
+Javert se levait au moment où l'exprès lui remit l'ordre d'arrestation\r
+et le mandat d'amener.\r
+\r
+L'exprès était lui-même un homme de police fort entendu qui, en deux\r
+mots, mit Javert au fait de ce qui était arrivé à Arras. L'ordre\r
+d'arrestation, signé de l'avocat général, était ainsi\r
+conçu:--L'inspecteur Javert appréhendera au corps le sieur Madeleine,\r
+maire de Montreuil-sur-mer, qui, dans l'audience de ce jour, a été\r
+reconnu pour être le forçat libéré Jean Valjean.\r
+\r
+Quelqu'un qui n'eût pas connu Javert et qui l'eût vu au moment où il\r
+pénétra dans l'antichambre de l'infirmerie n'eût pu rien deviner de ce\r
+qui se passait, et lui eût trouvé l'air le plus ordinaire du monde. Il\r
+était froid, calme, grave, avait ses cheveux gris parfaitement lissés\r
+sur les tempes et venait de monter l'escalier avec sa lenteur\r
+habituelle. Quelqu'un qui l'eût connu à fond et qui l'eût examiné\r
+attentivement eût frémi. La boucle de son col de cuir, au lieu d'être\r
+sur sa nuque, était sur son oreille gauche. Ceci révélait une agitation\r
+inouïe.\r
+\r
+Javert était un caractère complet, ne laissant faire de pli ni à son\r
+devoir, ni à son uniforme; méthodique avec les scélérats, rigide avec\r
+les boutons de son habit.\r
+\r
+Pour qu'il eût mal mis la boucle de son col, il fallait qu'il y eût en\r
+lui une de ces émotions qu'on pourrait appeler des tremblements de terre\r
+intérieurs.\r
+\r
+Il était venu simplement, avait requis un caporal et quatre soldats au\r
+poste voisin, avait laissé les soldats dans la cour, et s'était fait\r
+indiquer la chambre de Fantine par la portière sans défiance, accoutumée\r
+qu'elle était à voir des gens armés demander monsieur le maire.\r
+\r
+Arrivé à la chambre de Fantine, Javert tourna la clef, poussa la porte\r
+avec une douceur de garde-malade ou de mouchard, et entra.\r
+\r
+À proprement parler, il n'entra pas. Il se tint debout dans la porte\r
+entrebâillée, le chapeau sur la tête, la main gauche dans sa redingote\r
+fermée jusqu'au menton. Dans le pli du coude on pouvait voir le pommeau\r
+de plomb de son énorme canne, laquelle disparaissait derrière lui.\r
+\r
+Il resta ainsi près d'une minute sans qu'on s'aperçût de sa présence.\r
+Tout à coup Fantine leva les yeux, le vit, et fit retourner M.\r
+Madeleine.\r
+\r
+À l'instant où le regard de Madeleine rencontra le regard de Javert,\r
+Javert, sans bouger, sans remuer, sans approcher, devint épouvantable.\r
+Aucun sentiment humain ne réussit à être effroyable comme la joie.\r
+\r
+Ce fut le visage d'un démon qui vient de retrouver son damné.\r
+\r
+La certitude de tenir enfin Jean Valjean fit apparaître sur sa\r
+physionomie tout ce qu'il avait dans l'âme. Le fond remué monta à la\r
+surface. L'humiliation d'avoir un peu perdu la piste et de s'être mépris\r
+quelques minutes sur ce Champmathieu, s'effaçait sous l'orgueil d'avoir\r
+si bien deviné d'abord et d'avoir eu si longtemps un instinct juste. Le\r
+contentement de Javert éclata dans son attitude souveraine. La\r
+difformité du triomphe s'épanouit sur ce front étroit. Ce fut tout le\r
+déploiement d'horreur que peut donner une figure satisfaite.\r
+\r
+Javert en ce moment était au ciel. Sans qu'il s'en rendit nettement\r
+compte, mais pourtant avec une intuition confuse de sa nécessité et de\r
+son succès, il personnifiait, lui Javert, la justice, la lumière et la\r
+vérité dans leur fonction céleste d'écrasement du mal. Il avait derrière\r
+lui et autour de lui, à une profondeur infinie, l'autorité, la raison,\r
+la chose jugée, la conscience légale, la vindicte publique, toutes les\r
+étoiles; il protégeait l'ordre, il faisait sortir de la loi la foudre,\r
+il vengeait la société, il prêtait main-forte à l'absolu; il se dressait\r
+dans une gloire; il y avait dans sa victoire un reste de défi et de\r
+combat; debout, altier, éclatant, il étalait en plein azur la bestialité\r
+surhumaine d'un archange féroce; l'ombre redoutable de l'action qu'il\r
+accomplissait faisait visible à son poing crispé le vague flamboiement\r
+de l'épée sociale; heureux et indigné, il tenait sous son talon le\r
+crime, le vice, la rébellion, la perdition, l'enfer, il rayonnait, il\r
+exterminait, il souriait et il y avait une incontestable grandeur dans\r
+ce saint Michel monstrueux.\r
+\r
+Javert, effroyable, n'avait rien d'ignoble.\r
+\r
+La probité, la sincérité, la candeur, la conviction, l'idée du devoir,\r
+sont des choses qui, en se trompant, peuvent devenir hideuses, mais qui,\r
+même hideuses, restent grandes; leur majesté, propre à la conscience\r
+humaine, persiste dans l'horreur. Ce sont des vertus qui ont un vice,\r
+l'erreur. L'impitoyable joie honnête d'un fanatique en pleine atrocité\r
+conserve on ne sait quel rayonnement lugubrement vénérable. Sans qu'il\r
+s'en doutât, Javert, dans son bonheur formidable, était à plaindre comme\r
+tout ignorant qui triomphe. Rien n'était poignant et terrible comme\r
+cette figure où se montrait ce qu'on pourrait appeler tout le mauvais du\r
+bon.\r
+\r
+\r
+\r
+\r
+Chapitre IV\r
+\r
+L'autorité reprend ses droits\r
+\r
+\r
+La Fantine n'avait point vu Javert depuis le jour où M. le maire l'avait\r
+arrachée à cet homme. Son cerveau malade ne se rendit compte de rien,\r
+seulement elle ne douta pas qu'il ne revint la chercher. Elle ne put\r
+supporter cette figure affreuse, elle se sentit expirer, elle cacha son\r
+visage de ses deux mains et cria avec angoisse:\r
+\r
+--Monsieur Madeleine, sauvez-moi!\r
+\r
+Jean Valjean--nous ne le nommerons plus désormais autrement--s'était\r
+levé. Il dit à Fantine de sa voix la plus douce et la plus calme:\r
+\r
+--Soyez tranquille. Ce n'est pas pour vous qu'il vient.\r
+\r
+Puis il s'adressa à Javert et lui dit:\r
+\r
+--Je sais ce que vous voulez.\r
+\r
+Javert répondit:\r
+\r
+--Allons, vite!\r
+\r
+Il y eut dans l'inflexion qui accompagna ces deux mots je ne sais quoi\r
+de fauve et de frénétique. Javert ne dit pas: «Allons, vite!» il dit:\r
+«Allonouaite!» Aucune orthographe ne pourrait rendre l'accent dont cela\r
+fut prononcé; ce n'était plus une parole humaine, c'était un\r
+rugissement.\r
+\r
+Il ne fit point comme d'habitude; il n'entra point en matière; il\r
+n'exhiba point de mandat d'amener. Pour lui, Jean Valjean était une\r
+sorte de combattant mystérieux et insaisissable, un lutteur ténébreux\r
+qu'il étreignait depuis cinq ans sans pouvoir le renverser. Cette\r
+arrestation n'était pas un commencement, mais une fin. Il se borna à\r
+dire: «Allons, vite!»\r
+\r
+En parlant ainsi, il ne fit point un pas; il lança sur Jean Valjean ce\r
+regard qu'il jetait comme un crampon, et avec lequel il avait coutume de\r
+tirer violemment les misérables à lui.\r
+\r
+C'était ce regard que la Fantine avait senti pénétrer jusque dans la\r
+moelle de ses os deux mois auparavant.\r
+\r
+Au cri de Javert, Fantine avait rouvert les yeux. Mais M. le maire était\r
+là. Que pouvait-elle craindre?\r
+\r
+Javert avança au milieu de la chambre et cria:\r
+\r
+--Ah çà! viendras-tu?\r
+\r
+La malheureuse regarda autour d'elle. Il n'y avait personne que la\r
+religieuse et monsieur le maire. À qui pouvait s'adresser ce tutoiement\r
+abject? elle seulement. Elle frissonna.\r
+\r
+Alors elle vit une chose inouïe, tellement inouïe que jamais rien de\r
+pareil ne lui était apparu dans les plus noirs délires de la fièvre.\r
+\r
+Elle vit le mouchard Javert saisir au collet monsieur le maire; elle vit\r
+monsieur le maire courber la tête. Il lui sembla que le monde\r
+s'évanouissait.\r
+\r
+Javert, en effet, avait pris Jean Valjean au collet.\r
+\r
+--Monsieur le maire! cria Fantine.\r
+\r
+Javert éclata de rire, de cet affreux rire qui lui déchaussait toutes\r
+les dents.\r
+\r
+--Il n'y a plus de monsieur le maire ici!\r
+\r
+Jean Valjean n'essaya pas de déranger la main qui tenait le col de sa\r
+redingote. Il dit:\r
+\r
+--Javert....\r
+\r
+Javert l'interrompit:\r
+\r
+--Appelle-moi monsieur l'inspecteur.\r
+\r
+--Monsieur, reprit Jean Valjean, je voudrais vous dire un mot en\r
+particulier.\r
+\r
+--Tout haut! parle tout haut! répondit Javert; on me parle tout haut à\r
+moi!\r
+\r
+Jean Valjean continua en baissant la voix:\r
+\r
+--C'est une prière que j'ai à vous faire....\r
+\r
+--Je te dis de parler tout haut.\r
+\r
+--Mais cela ne doit être entendu que de vous seul....\r
+\r
+--Qu'est-ce que cela me fait? je n'écoute pas!\r
+\r
+Jean Valjean se tourna vers lui et lui dit rapidement et très bas:\r
+\r
+--Accordez-moi trois jours! trois jours pour aller chercher l'enfant de\r
+cette malheureuse femme! Je payerai ce qu'il faudra. Vous\r
+m'accompagnerez si vous voulez.\r
+\r
+--Tu veux rire! cria Javert. Ah çà! je ne te croyais pas bête! Tu me\r
+demandes trois jours pour t'en aller! Tu dis que c'est pour aller\r
+chercher l'enfant de cette fille! Ah! ah! c'est bon! voilà qui est bon!\r
+Fantine eut un tremblement.\r
+\r
+--Mon enfant! s'écria-t-elle, aller chercher mon enfant! Elle n'est donc\r
+pas ici! Ma soeur, répondez-moi, où est Cosette? Je veux mon enfant!\r
+Monsieur Madeleine! monsieur le maire!\r
+\r
+Javert frappa du pied.\r
+\r
+--Voilà l'autre, à présent! Te tairas-tu, drôlesse! Gredin de pays où\r
+les galériens sont magistrats et où les filles publiques sont soignées\r
+comme des comtesses! Ah mais! tout ça va changer; il était temps!\r
+\r
+Il regarda fixement Fantine et ajouta en reprenant à poignée la cravate,\r
+la chemise et le collet de Jean Valjean:\r
+\r
+--Je te dis qu'il n'y a point de monsieur Madeleine et qu'il n'y a point\r
+de monsieur le maire. Il y a un voleur, il y a un brigand, il y a un\r
+forçat appelé Jean Valjean! c'est lui que je tiens! voilà ce qu'il y a!\r
+\r
+Fantine se dressa en sursaut, appuyée sur ses bras roides et sur ses\r
+deux mains, elle regarda Jean Valjean, elle regarda Javert, elle regarda\r
+la religieuse, elle ouvrit la bouche comme pour parler, un râle sortit\r
+du fond de sa gorge, ses dents claquèrent, elle étendit les bras avec\r
+angoisse, ouvrant convulsivement les mains, et cherchant autour d'elle\r
+comme quelqu'un qui se noie, puis elle s'affaissa subitement sur\r
+l'oreiller. Sa tête heurta le chevet du lit et vint retomber sur sa\r
+poitrine, la bouche béante, les yeux ouverts et éteints.\r
+\r
+Elle était morte.\r
+\r
+Jean Valjean posa sa main sur la main de Javert qui le tenait, et\r
+l'ouvrit comme il eût ouvert la main d'un enfant, puis il dit à Javert:\r
+\r
+--Vous avez tué cette femme.\r
+\r
+--Finirons-nous! cria Javert furieux. Je ne suis pas ici pour entendre\r
+des raisons. Économisons tout ça. La garde est en bas. Marchons tout de\r
+suite, ou les poucettes!\r
+\r
+Il y avait dans un coin de la chambre un vieux lit en fer en assez\r
+mauvais état qui servait de lit de camp aux soeurs quand elles\r
+veillaient. Jean Valjean alla à ce lit, disloqua en un clin d'oeil le\r
+chevet déjà fort délabré, chose facile à des muscles comme les siens,\r
+saisit à poigne-main la maîtresse-tringle, et considéra Javert. Javert\r
+recula vers la porte.\r
+\r
+Jean Valjean, sa barre de fer au poing, marcha lentement vers le lit de\r
+Fantine. Quand il y fut parvenu, il se retourna, et dit à Javert d'une\r
+voix qu'on entendait à peine:\r
+\r
+--Je ne vous conseille pas de me déranger en ce moment.\r
+\r
+Ce qui est certain, c'est que Javert tremblait.\r
+\r
+Il eut l'idée d'aller appeler la garde, mais Jean Valjean pouvait\r
+profiter de cette minute pour s'évader. Il resta donc, saisit sa canne\r
+par le petit bout, et s'adossa au chambranle de la porte sans quitter du\r
+regard Jean Valjean.\r
+\r
+Jean Valjean posa son coude sur la pomme du chevet du lit et son front\r
+sur sa main, et se mit à contempler Fantine immobile et étendue. Il\r
+demeura ainsi, absorbé, muet, et ne songeant évidemment plus à aucune\r
+chose de cette vie. Il n'y avait plus rien sur son visage et dans son\r
+attitude qu'une inexprimable pitié. Après quelques instants de cette\r
+rêverie, il se pencha vers Fantine et lui parla à voix basse.\r
+\r
+Que lui dit-il? Que pouvait dire cet homme qui était réprouvé à cette\r
+femme qui était morte? Qu'était-ce que ces paroles? Personne sur la\r
+terre ne les a entendues. La morte les entendit-elle? Il y a des\r
+illusions touchantes qui sont peut-être des réalités sublimes. Ce qui\r
+est hors de doute, c'est que la soeur Simplice, unique témoin de la\r
+chose qui se passait, a souvent raconté qu'au moment où Jean Valjean\r
+parla à l'oreille de Fantine, elle vit distinctement poindre un\r
+ineffable sourire sur ces lèvres pâles et dans ces prunelles vagues,\r
+pleines de l'étonnement du tombeau.\r
+\r
+Jean Valjean prit dans ses deux mains la tête de Fantine et l'arrangea\r
+sur l'oreiller comme une mère eût fait pour son enfant, il lui rattacha\r
+le cordon de sa chemise et rentra ses cheveux sous son bonnet. Cela\r
+fait, il lui ferma les yeux.\r
+\r
+La face de Fantine en cet instant semblait étrangement éclairée.\r
+\r
+La mort, c'est l'entrée dans la grande lueur.\r
+\r
+La main de Fantine pendait hors du lit. Jean Valjean s'agenouilla devant\r
+cette main, la souleva doucement, et la baisa.\r
+\r
+Puis il se redressa, et, se tournant vers Javert:\r
+\r
+--Maintenant, dit-il, je suis à vous.\r

+Chapitre V\r
+\r
+Tombeau convenable\r
+\r
+\r
+Javert déposa Jean Valjean à la prison de la ville.\r
+\r
+L'arrestation de M. Madeleine produisit à Montreuil-sur-mer une\r
+sensation, ou pour mieux dire une commotion extraordinaire. Nous sommes\r
+triste de ne pouvoir dissimuler que sur ce seul mot: _c'était un\r
+galérien_, tout le monde à peu près l'abandonna. En moins de deux heures\r
+tout le bien qu'il avait fait fut oublié, et ce ne fut plus «qu'un\r
+galérien». Il est juste de dire qu'on ne connaissait pas encore les\r
+détails de l'événement d'Arras. Toute la journée on entendait dans\r
+toutes les parties de la ville des conversations comme celle-ci:\r
+\r
+--Vous ne savez pas? c'était un forçat libéré! Qui ça?--Le maire.--Bah!\r
+M. Madeleine?--Oui. Vraiment?--Il ne s'appelait pas Madeleine, il a un\r
+affreux nom, Béjean, Bojean, Boujean.--Ah, mon Dieu!--Il est\r
+arrêté.--Arrêté!--En prison à la prison de la ville, en attendant qu'on\r
+le transfère.--Qu'on le transfère! On va le transférer! Où va-t-on le\r
+transférer?--Il va passer aux assises pour un vol de grand chemin qu'il\r
+a fait autrefois.--Eh bien! je m'en doutais. Cet homme était trop bon,\r
+trop parfait, trop confit. Il refusait la croix, il donnait des sous à\r
+tous les petits drôles qu'il rencontrait. J'ai toujours pensé qu'il y\r
+avait là-dessous quelque mauvaise histoire.\r
+\r
+«Les salons» surtout abondèrent dans ce sens.\r
+\r
+Une vieille dame, abonnée au _Drapeau blanc_, fit cette réflexion dont\r
+il est presque impossible de sonder la profondeur:\r
+\r
+--Je n'en suis pas fâchée. Cela apprendra aux buonapartistes!\r
+\r
+C'est ainsi que ce fantôme qui s'était appelé M. Madeleine se dissipa à\r
+Montreuil-sur-mer. Trois ou quatre personnes seulement dans toute la\r
+ville restèrent fidèles à cette mémoire. La vieille portière qui l'avait\r
+servi fut du nombre. Le soir de ce même jour, cette digne vieille était\r
+assise dans sa loge, encore tout effarée et réfléchissant tristement. La\r
+fabrique avait été fermée toute la journée, la porte cochère était\r
+verrouillée, la rue était déserte. Il n'y avait dans la maison que deux\r
+religieuses, soeur Perpétue et soeur Simplice, qui veillaient près du\r
+corps de Fantine.\r
+\r
+Vers l'heure où M. Madeleine avait coutume de rentrer, la brave portière\r
+se leva machinalement, prit la clef de la chambre de M. Madeleine dans\r
+un tiroir et le bougeoir dont il se servait tous les soirs pour monter\r
+chez lui, puis elle accrocha la clef au clou où il la prenait\r
+d'habitude, et plaça le bougeoir à côté, comme si elle l'attendait.\r
+Ensuite elle se rassit sur sa chaise et se remit à songer. La pauvre\r
+bonne vieille avait fait tout cela sans en avoir conscience.\r
+\r
+Ce ne fut qu'au bout de plus de deux heures qu'elle sortit de sa rêverie\r
+et s'écria: «Tiens! mon bon Dieu Jésus! moi qui ai mis sa clef au clou!»\r
+\r
+En ce moment la vitre de la loge s'ouvrit, une main passa par\r
+l'ouverture, saisit la clef et le bougeoir et alluma la bougie à la\r
+chandelle qui brûlait.\r
+\r
+La portière leva les yeux et resta béante, avec un cri dans le gosier\r
+qu'elle retint. Elle connaissait cette main, ce bras, cette manche de\r
+redingote.\r
+\r
+C'était M. Madeleine.\r
+\r
+Elle fut quelques secondes avant de pouvoir parler, saisie, comme elle\r
+le disait elle-même plus tard en racontant son aventure.\r
+\r
+--Mon Dieu, monsieur le maire, s'écria-t-elle enfin, je vous croyais....\r
+\r
+Elle s'arrêta, la fin de sa phrase eût manqué de respect au\r
+commencement. Jean Valjean était toujours pour elle monsieur le maire.\r
+\r
+Il acheva sa pensée.\r
+\r
+--En prison, dit-il. J'y étais. J'ai brisé un barreau d'une fenêtre, je\r
+me suis laissé tomber du haut d'un toit, et me voici. Je monte à ma\r
+chambre, allez me chercher la soeur Simplice. Elle est sans doute près\r
+de cette pauvre femme.\r
+\r
+La vieille obéit en toute hâte.\r
+\r
+Il ne lui fit aucune recommandation; il était bien sûr qu'elle le\r
+garderait mieux qu'il ne se garderait lui-même.\r
+\r
+On n'a jamais su comment il avait réussi à pénétrer dans la cour sans\r
+faire ouvrir la porte cochère. Il avait, et portait toujours sur lui, un\r
+passe-partout qui ouvrait une petite porte latérale; mais on avait dû le\r
+fouiller et lui prendre son passe-partout. Ce point n'a pas été\r
+éclairci.\r
+\r
+Il monta l'escalier qui conduisait à sa chambre. Arrivé en haut, il\r
+laissa son bougeoir sur les dernières marches de l'escalier, ouvrit sa\r
+porte avec peu de bruit, et alla fermer à tâtons sa fenêtre et son\r
+volet, puis il revint prendre sa bougie et rentra dans sa chambre.\r
+\r
+La précaution était utile; on se souvient que sa fenêtre pouvait être\r
+aperçue de la rue. Il jeta un coup d'oeil autour de lui, sur sa table,\r
+sur sa chaise, sur son lit qui n'avait pas été défait depuis trois\r
+jours. Il ne restait aucune trace du désordre de l'avant-dernière nuit.\r
+La portière avait «fait la chambre». Seulement elle avait ramassé dans\r
+les cendres et posé proprement sur la table les deux bouts du bâton\r
+ferré et la pièce de quarante sous noircie par le feu.\r
+\r
+Il prit une feuille de papier sur laquelle il écrivit: _Voici les deux\r
+bouts de mon bâton ferré et la pièce de quarante sous volée à\r
+Petit-Gervais dont j'ai parlé à la cour d'assises_, et il posa sur cette\r
+feuille la pièce d'argent et les deux morceaux de fer, de façon que ce\r
+fût la première chose qu'on aperçût en entrant dans la chambre. Il tira\r
+d'une armoire une vieille chemise à lui qu'il déchira. Cela fit quelques\r
+morceaux de toile dans lesquels il emballa les deux flambeaux d'argent.\r
+Du reste il n'avait ni hâte ni agitation, et, tout en emballant les\r
+chandeliers de l'évêque, il mordait dans un morceau de pain noir. Il est\r
+probable que c'était le pain de la prison qu'il avait emporté en\r
+s'évadant.\r
+\r
+Ceci a été constaté par les miettes de pain qui furent trouvées sur le\r
+carreau de la chambre, lorsque la justice plus tard fit une\r
+perquisition.\r
+\r
+On frappa deux petits coups à la porte.\r
+\r
+--Entrez, dit-il.\r
+\r
+C'était la soeur Simplice.\r
+\r
+Elle était pâle, elle avait les yeux rouges, la chandelle qu'elle tenait\r
+vacillait dans sa main. Les violences de la destinée ont cela de\r
+particulier que, si perfectionnés ou si refroidis que nous soyons, elles\r
+nous tirent du fond des entrailles la nature humaine et la forcent de\r
+reparaître au dehors. Dans les émotions de cette journée, la religieuse\r
+était redevenue femme. Elle avait pleuré, et elle tremblait.\r
+\r
+Jean Valjean venait d'écrire quelques lignes sur un papier qu'il tendit\r
+à la religieuse en disant:\r
+\r
+--Ma soeur, vous remettrez ceci à monsieur le curé.\r
+\r
+Le papier était déplié. Elle y jeta les yeux.\r
+\r
+--Vous pouvez lire, dit-il.\r
+\r
+Elle lut.--«Je prie monsieur le curé de veiller sur tout ce que je\r
+laisse ici. Il voudra bien payer là-dessus les frais de mon procès et\r
+l'enterrement de la femme qui est morte aujourd'hui. Le reste sera aux\r
+pauvres.»\r
+\r
+La soeur voulut parler, mais elle put à peine balbutier quelques sons\r
+inarticulés. Elle parvint cependant à dire:\r
+\r
+--Est-ce que monsieur le maire ne désire pas revoir une dernière fois\r
+cette pauvre malheureuse?\r
+\r
+--Non, dit-il, on est à ma poursuite, on n'aurait qu'à m'arrêter dans sa\r
+chambre, cela la troublerait.\r
+\r
+Il achevait à peine qu'un grand bruit se fit dans l'escalier. Ils\r
+entendirent un tumulte de pas qui montaient, et la vieille portière qui\r
+disait de sa voix la plus haute et la plus perçante:\r
+\r
+--Mon bon monsieur, je vous jure le bon Dieu qu'il n'est entré personne\r
+ici de toute la journée ni de toute la soirée, que même je n'ai pas\r
+quitté ma porte!\r
+\r
+Un homme répondit:\r
+\r
+--Cependant il y a de la lumière dans cette chambre.\r
+\r
+Ils reconnurent la voix de Javert.\r
+\r
+La chambre était disposée de façon que la porte en s'ouvrant masquait\r
+l'angle du mur à droite. Jean Valjean souffla la bougie et se mit dans\r
+cet angle.\r
+\r
+La soeur Simplice tomba à genoux près de la table.\r
+\r
+La porte s'ouvrit.\r
+\r
+Javert entra.\r
+\r
+On entendait le chuchotement de plusieurs hommes et les protestations de\r
+la portière dans le corridor.\r
+\r
+La religieuse ne leva pas les yeux. Elle priait.\r
+\r
+La chandelle était sur la cheminée et ne donnait que peu de clarté.\r
+\r
+Javert aperçut la soeur et s'arrêta interdit.\r
+\r
+On se rappelle que le fond même de Javert, son élément, son milieu\r
+respirable, c'était la vénération de toute autorité. Il était tout d'une\r
+pièce et n'admettait ni objection, ni restriction. Pour lui, bien\r
+entendu, l'autorité ecclésiastique était la première de toutes. Il était\r
+religieux, superficiel et correct sur ce point comme sur tous. À ses\r
+yeux un prêtre était un esprit qui ne se trompe pas, une religieuse\r
+était une créature qui ne pèche pas. C'étaient des âmes murées à ce\r
+monde avec une seule porte qui ne s'ouvrait jamais que pour laisser\r
+sortir la vérité.\r
+\r
+En apercevant la soeur, son premier mouvement fut de se retirer.\r
+\r
+Cependant il y avait aussi un autre devoir qui le tenait, et qui le\r
+poussait impérieusement en sens inverse. Son second mouvement fut de\r
+rester, et de hasarder au moins une question.\r
+\r
+C'était cette soeur Simplice qui n'avait menti de sa vie. Javert le\r
+savait, et la vénérait particulièrement à cause de cela.\r
+\r
+--Ma soeur, dit-il, êtes-vous seule dans cette chambre?\r
+\r
+Il y eut un moment affreux pendant lequel la pauvre portière se sentit\r
+défaillir.\r
+\r
+La soeur leva les yeux et répondit:\r
+\r
+--Oui.\r
+\r
+--Ainsi, reprit Javert, excusez-moi si j'insiste, c'est mon devoir, vous\r
+n'avez pas vu ce soir une personne, un homme. Il s'est évadé, nous le\r
+cherchons, ce nommé Jean Valjean, vous ne l'avez pas vu?\r
+\r
+La soeur répondit:\r
+\r
+--Non.\r
+\r
+Elle mentit. Elle mentit deux fois de suite, coup sur coup, sans\r
+hésiter, rapidement, comme on se dévoue.\r
+\r
+--Pardon, dit Javert, et il se retira en saluant profondément.\r
+\r
+Ô sainte fille! vous n'êtes plus de ce monde depuis beaucoup d'années;\r
+vous avez rejoint dans la lumière vos soeurs les vierges et vos frères\r
+les anges; que ce mensonge vous soit compté dans le paradis!\r
+\r
+L'affirmation de la soeur fut pour Javert quelque chose de si décisif\r
+qu'il ne remarqua même pas la singularité de cette bougie qu'on venait\r
+de souffler et qui fumait sur la table.\r
+\r
+Une heure après, un homme, marchant à travers les arbres et les brumes,\r
+s'éloignait rapidement de Montreuil-sur-mer dans la direction de Paris.\r
+Cet homme était Jean Valjean. Il a été établi, par le témoignage de deux\r
+ou trois rouliers qui l'avaient rencontré, qu'il portait un paquet et\r
+qu'il était vêtu d'une blouse. Où avait-il pris cette blouse? On ne l'a\r
+jamais su. Cependant un vieux ouvrier était mort quelques jours\r
+auparavant à l'infirmerie de la fabrique, ne laissant que sa blouse.\r
+C'était peut-être celle-là.\r
+\r
+Un dernier mot sur Fantine.\r
+\r
+Nous avons tous une mère, la terre. On rendit Fantine à cette mère.\r
+\r
+Le curé crut bien faire, et fit bien peut-être, en réservant, sur ce que\r
+Jean Valjean avait laissé, le plus d'argent possible aux pauvres. Après\r
+tout, de qui s'agissait-il? d'un forçat et d'une fille publique. C'est\r
+pourquoi il simplifia l'enterrement de Fantine, et le réduisit à ce\r
+strict nécessaire qu'on appelle la fosse commune.\r
+\r
+Fantine fut donc enterrée dans ce coin gratis du cimetière qui est à\r
+tous et à personne, et où l'on perd les pauvres. Heureusement Dieu sait\r
+où retrouver l'âme. On coucha Fantine dans les ténèbres parmi les\r
+premiers os venus; elle subit la promiscuité des cendres. Elle fut jetée\r
+à la fosse publique. Sa tombe ressembla à son lit.\r

+\r
+Section 2. Information about the Mission of Project Gutenberg-tm\r
+\r
+Project Gutenberg-tm is synonymous with the free distribution of\r
+electronic works in formats readable by the widest variety of computers\r
+including obsolete, old, middle-aged and new computers. It exists\r
+because of the efforts of hundreds of volunteers and donations from\r
+people in all walks of life.\r
+\r
+Volunteers and financial support to provide volunteers with the\r
+assistance they need, is critical to reaching Project Gutenberg-tm's\r
+goals and ensuring that the Project Gutenberg-tm collection will\r
+remain freely available for generations to come. In 2001, the Project\r
+Gutenberg Literary Archive Foundation was created to provide a secure\r
+and permanent future for Project Gutenberg-tm and future generations.\r
+To learn more about the Project Gutenberg Literary Archive Foundation\r
+and how your efforts and donations can help, see Sections 3 and 4\r
+and the Foundation web page at http://www.pglaf.org.\r
+\r
+\r
+Section 3. Information about the Project Gutenberg Literary Archive\r
+Foundation\r

+The Project Gutenberg Literary Archive Foundation is a non profit\r
+501(c)(3) educational corporation organized under the laws of the\r
+state of Mississippi and granted tax exempt status by the Internal\r
+Revenue Service. The Foundation's EIN or federal tax identification\r
+number is 64-6221541. Its 501(c)(3) letter is posted at\r
+http://pglaf.org/fundraising. Contributions to the Project Gutenberg\r
+Literary Archive Foundation are tax deductible to the full extent\r
+permitted by U.S. federal laws and your state's laws.\r

+\r
+Section 4. Information about Donations to the Project Gutenberg\r
+Literary Archive Foundation\r
+\r
+Project Gutenberg-tm depends upon and cannot survive without wide\r
+spread public support and donations to carry out its mission of\r
+increasing the number of public domain and licensed works that can be\r
+freely distributed in machine readable form accessible by the widest\r
+array of equipment including outdated equipment. Many small donations\r
+($1 to $5,000) are particularly important to maintaining tax exempt\r
+status with the IRS.\r
+\r
+The Foundation is committed to complying with the laws regulating\r
+charities and charitable donations in all 50 states of the United\r
+States. Compliance requirements are not uniform and it takes a\r
+considerable effort, much paperwork and many fees to meet and keep up\r
+with these requirements. We do not solicit donations in locations\r
+where we have not received written confirmation of compliance. To\r
+SEND DONATIONS or determine the status of compliance for any\r
+particular state visit http://pglaf.org\r
+\r
+While we cannot and do not solicit contributions from states where we\r
+have not met the solicitation requirements, we know of no prohibition\r
+against accepting unsolicited donations from donors in such states who\r
+approach us with offers to donate.\r
+\r
+International donations are gratefully accepted, but we cannot make\r
+any statements concerning tax treatment of donations received from\r
+outside the United States. U.S. laws alone swamp our small staff.\r
+\r
+Please check the Project Gutenberg Web pages for current donation\r
+methods and addresses. Donations are accepted in a number of other\r
+ways including checks, online payments and credit card\r
+donations. To donate, please visit: http://pglaf.org/donate\r
+\r
+\r
+Section 5. General Information About Project Gutenberg-tm electronic\r
+works.\r
+\r
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm\r
+concept of a library of electronic works that could be freely shared\r
+with anyone. For thirty years, he produced and distributed Project\r
+Gutenberg-tm eBooks with only a loose network of volunteer support.\r
+\r
+Project Gutenberg-tm eBooks are often created from several printed\r
+editions, all of which are confirmed as Public Domain in the U.S.\r
+unless a copyright notice is included. Thus, we do not necessarily\r
+keep eBooks in compliance with any particular paper edition.\r
+\r
+Most people start at our Web site which has the main PG search facility:\r
+\r
+ http://www.gutenberg.org\r
+\r
+This Web site includes information about Project Gutenberg-tm,\r
+including how to make donations to the Project Gutenberg Literary\r
+Archive Foundation, how to help produce our new eBooks, and how to\r
+subscribe to our email newsletter to hear about new eBooks.\r

+THE PREFACE\r
+\r
+The artist is the creator of beautiful things. To reveal art and\r
+conceal the artist is art's aim. The critic is he who can translate\r
+into another manner or a new material his impression of beautiful\r
+things.\r
+\r
+The highest as the lowest form of criticism is a mode of autobiography.\r
+Those who find ugly meanings in beautiful things are corrupt without\r
+being charming. This is a fault.\r
+\r
+Those who find beautiful meanings in beautiful things are the\r
+cultivated. For these there is hope. They are the elect to whom\r
+beautiful things mean only beauty.\r
+\r
+There is no such thing as a moral or an immoral book. Books are well\r
+written, or badly written. That is all.\r
+\r
+The nineteenth century dislike of realism is the rage of Caliban seeing\r
+his own face in a glass.\r
+\r
+The nineteenth century dislike of romanticism is the rage of Caliban\r
+not seeing his own face in a glass. The moral life of man forms part\r
+of the subject-matter of the artist, but the morality of art consists\r
+in the perfect use of an imperfect medium. No artist desires to prove\r
+anything. Even things that are true can be proved. No artist has\r
+ethical sympathies. An ethical sympathy in an artist is an\r
+unpardonable mannerism of style. No artist is ever morbid. The artist\r
+can express everything. Thought and language are to the artist\r
+instruments of an art. Vice and virtue are to the artist materials for\r
+an art. From the point of view of form, the type of all the arts is\r
+the art of the musician. From the point of view of feeling, the\r
+actor's craft is the type. All art is at once surface and symbol.\r
+Those who go beneath the surface do so at their peril. Those who read\r
+the symbol do so at their peril. It is the spectator, and not life,\r
+that art really mirrors. Diversity of opinion about a work of art\r
+shows that the work is new, complex, and vital. When critics disagree,\r
+the artist is in accord with himself. We can forgive a man for making\r
+a useful thing as long as he does not admire it. The only excuse for\r
+making a useless thing is that one admires it intensely.\r
+\r
+ All art is quite useless.\r
+\r

+CHAPTER 1\r
+\r
+The studio was filled with the rich odour of roses, and when the light\r
+summer wind stirred amidst the trees of the garden, there came through\r
+the open door the heavy scent of the lilac, or the more delicate\r
+perfume of the pink-flowering thorn.\r
+\r
+From the corner of the divan of Persian saddle-bags on which he was\r
+lying, smoking, as was his custom, innumerable cigarettes, Lord Henry\r
+Wotton could just catch the gleam of the honey-sweet and honey-coloured\r
+blossoms of a laburnum, whose tremulous branches seemed hardly able to\r
+bear the burden of a beauty so flamelike as theirs; and now and then\r
+the fantastic shadows of birds in flight flitted across the long\r
+tussore-silk curtains that were stretched in front of the huge window,\r
+producing a kind of momentary Japanese effect, and making him think of\r
+those pallid, jade-faced painters of Tokyo who, through the medium of\r
+an art that is necessarily immobile, seek to convey the sense of\r
+swiftness and motion. The sullen murmur of the bees shouldering their\r
+way through the long unmown grass, or circling with monotonous\r
+insistence round the dusty gilt horns of the straggling woodbine,\r
+seemed to make the stillness more oppressive. The dim roar of London\r
+was like the bourdon note of a distant organ.\r
+\r
+In the centre of the room, clamped to an upright easel, stood the\r
+full-length portrait of a young man of extraordinary personal beauty,\r
+and in front of it, some little distance away, was sitting the artist\r
+himself, Basil Hallward, whose sudden disappearance some years ago\r
+caused, at the time, such public excitement and gave rise to so many\r
+strange conjectures.\r
+\r
+As the painter looked at the gracious and comely form he had so\r
+skilfully mirrored in his art, a smile of pleasure passed across his\r
+face, and seemed about to linger there. But he suddenly started up,\r
+and closing his eyes, placed his fingers upon the lids, as though he\r
+sought to imprison within his brain some curious dream from which he\r
+feared he might awake.\r
+\r
+"It is your best work, Basil, the best thing you have ever done," said\r
+Lord Henry languidly. "You must certainly send it next year to the\r
+Grosvenor. The Academy is too large and too vulgar. Whenever I have\r
+gone there, there have been either so many people that I have not been\r
+able to see the pictures, which was dreadful, or so many pictures that\r
+I have not been able to see the people, which was worse. The Grosvenor\r
+is really the only place."\r
+\r
+"I don't think I shall send it anywhere," he answered, tossing his head\r
+back in that odd way that used to make his friends laugh at him at\r
+Oxford. "No, I won't send it anywhere."\r
+\r
+Lord Henry elevated his eyebrows and looked at him in amazement through\r
+the thin blue wreaths of smoke that curled up in such fanciful whorls\r
+from his heavy, opium-tainted cigarette. "Not send it anywhere? My\r
+dear fellow, why? Have you any reason? What odd chaps you painters\r
+are! You do anything in the world to gain a reputation. As soon as\r
+you have one, you seem to want to throw it away. It is silly of you,\r
+for there is only one thing in the world worse than being talked about,\r
+and that is not being talked about. A portrait like this would set you\r
+far above all the young men in England, and make the old men quite\r
+jealous, if old men are ever capable of any emotion."\r
+\r
+"I know you will laugh at me," he replied, "but I really can't exhibit\r
+it. I have put too much of myself into it."\r
+\r
+Lord Henry stretched himself out on the divan and laughed.\r
+\r
+"Yes, I knew you would; but it is quite true, all the same."\r
+\r
+"Too much of yourself in it! Upon my word, Basil, I didn't know you\r
+were so vain; and I really can't see any resemblance between you, with\r
+your rugged strong face and your coal-black hair, and this young\r
+Adonis, who looks as if he was made out of ivory and rose-leaves. Why,\r
+my dear Basil, he is a Narcissus, and you--well, of course you have an\r
+intellectual expression and all that. But beauty, real beauty, ends\r
+where an intellectual expression begins. Intellect is in itself a mode\r
+of exaggeration, and destroys the harmony of any face. The moment one\r
+sits down to think, one becomes all nose, or all forehead, or something\r
+horrid. Look at the successful men in any of the learned professions.\r
+How perfectly hideous they are! Except, of course, in the Church. But\r
+then in the Church they don't think. A bishop keeps on saying at the\r
+age of eighty what he was told to say when he was a boy of eighteen,\r
+and as a natural consequence he always looks absolutely delightful.\r
+Your mysterious young friend, whose name you have never told me, but\r
+whose picture really fascinates me, never thinks. I feel quite sure of\r
+that. He is some brainless beautiful creature who should be always\r
+here in winter when we have no flowers to look at, and always here in\r
+summer when we want something to chill our intelligence. Don't flatter\r
+yourself, Basil: you are not in the least like him."\r
+\r
+"You don't understand me, Harry," answered the artist. "Of course I am\r
+not like him. I know that perfectly well. Indeed, I should be sorry\r
+to look like him. You shrug your shoulders? I am telling you the\r
+truth. There is a fatality about all physical and intellectual\r
+distinction, the sort of fatality that seems to dog through history the\r
+faltering steps of kings. It is better not to be different from one's\r
+fellows. The ugly and the stupid have the best of it in this world.\r
+They can sit at their ease and gape at the play. If they know nothing\r
+of victory, they are at least spared the knowledge of defeat. They\r
+live as we all should live--undisturbed, indifferent, and without\r
+disquiet. They neither bring ruin upon others, nor ever receive it\r
+from alien hands. Your rank and wealth, Harry; my brains, such as they\r
+are--my art, whatever it may be worth; Dorian Gray's good looks--we\r
+shall all suffer for what the gods have given us, suffer terribly."\r
+\r
+"Dorian Gray? Is that his name?" asked Lord Henry, walking across the\r
+studio towards Basil Hallward.\r
+\r
+"Yes, that is his name. I didn't intend to tell it to you."\r
+\r
+"But why not?"\r
+\r
+"Oh, I can't explain. When I like people immensely, I never tell their\r
+names to any one. It is like surrendering a part of them. I have\r
+grown to love secrecy. It seems to be the one thing that can make\r
+modern life mysterious or marvellous to us. The commonest thing is\r
+delightful if one only hides it. When I leave town now I never tell my\r
+people where I am going. If I did, I would lose all my pleasure. It\r
+is a silly habit, I dare say, but somehow it seems to bring a great\r
+deal of romance into one's life. I suppose you think me awfully\r
+foolish about it?"\r
+\r
+"Not at all," answered Lord Henry, "not at all, my dear Basil. You\r
+seem to forget that I am married, and the one charm of marriage is that\r
+it makes a life of deception absolutely necessary for both parties. I\r
+never know where my wife is, and my wife never knows what I am doing.\r
+When we meet--we do meet occasionally, when we dine out together, or go\r
+down to the Duke's--we tell each other the most absurd stories with the\r
+most serious faces. My wife is very good at it--much better, in fact,\r
+than I am. She never gets confused over her dates, and I always do.\r
+But when she does find me out, she makes no row at all. I sometimes\r
+wish she would; but she merely laughs at me."\r
+\r
+"I hate the way you talk about your married life, Harry," said Basil\r
+Hallward, strolling towards the door that led into the garden. "I\r
+believe that you are really a very good husband, but that you are\r
+thoroughly ashamed of your own virtues. You are an extraordinary\r
+fellow. You never say a moral thing, and you never do a wrong thing.\r
+Your cynicism is simply a pose."\r
+\r
+"Being natural is simply a pose, and the most irritating pose I know,"\r
+cried Lord Henry, laughing; and the two young men went out into the\r
+garden together and ensconced themselves on a long bamboo seat that\r
+stood in the shade of a tall laurel bush. The sunlight slipped over\r
+the polished leaves. In the grass, white daisies were tremulous.\r
+\r
+After a pause, Lord Henry pulled out his watch. "I am afraid I must be\r
+going, Basil," he murmured, "and before I go, I insist on your\r
+answering a question I put to you some time ago."\r
+\r
+"What is that?" said the painter, keeping his eyes fixed on the ground.\r
+\r
+"You know quite well."\r
+\r
+"I do not, Harry."\r
+\r
+"Well, I will tell you what it is. I want you to explain to me why you\r
+won't exhibit Dorian Gray's picture. I want the real reason."\r
+\r
+"I told you the real reason."\r
+\r
+"No, you did not. You said it was because there was too much of\r
+yourself in it. Now, that is childish."\r
+\r
+"Harry," said Basil Hallward, looking him straight in the face, "every\r
+portrait that is painted with feeling is a portrait of the artist, not\r
+of the sitter. The sitter is merely the accident, the occasion. It is\r
+not he who is revealed by the painter; it is rather the painter who, on\r
+the coloured canvas, reveals himself. The reason I will not exhibit\r
+this picture is that I am afraid that I have shown in it the secret of\r
+my own soul."\r
+\r
+Lord Henry laughed. "And what is that?" he asked.\r
+\r
+"I will tell you," said Hallward; but an expression of perplexity came\r
+over his face.\r
+\r
+"I am all expectation, Basil," continued his companion, glancing at him.\r
+\r
+"Oh, there is really very little to tell, Harry," answered the painter;\r
+"and I am afraid you will hardly understand it. Perhaps you will\r
+hardly believe it."\r
+\r
+Lord Henry smiled, and leaning down, plucked a pink-petalled daisy from\r
+the grass and examined it. "I am quite sure I shall understand it," he\r
+replied, gazing intently at the little golden, white-feathered disk,\r
+"and as for believing things, I can believe anything, provided that it\r
+is quite incredible."\r
+\r
+The wind shook some blossoms from the trees, and the heavy\r
+lilac-blooms, with their clustering stars, moved to and fro in the\r
+languid air. A grasshopper began to chirrup by the wall, and like a\r
+blue thread a long thin dragon-fly floated past on its brown gauze\r
+wings. Lord Henry felt as if he could hear Basil Hallward's heart\r
+beating, and wondered what was coming.\r
+\r
+"The story is simply this," said the painter after some time. "Two\r
+months ago I went to a crush at Lady Brandon's. You know we poor\r
+artists have to show ourselves in society from time to time, just to\r
+remind the public that we are not savages. With an evening coat and a\r
+white tie, as you told me once, anybody, even a stock-broker, can gain\r
+a reputation for being civilized. Well, after I had been in the room\r
+about ten minutes, talking to huge overdressed dowagers and tedious\r
+academicians, I suddenly became conscious that some one was looking at\r
+me. I turned half-way round and saw Dorian Gray for the first time.\r
+When our eyes met, I felt that I was growing pale. A curious sensation\r
+of terror came over me. I knew that I had come face to face with some\r
+one whose mere personality was so fascinating that, if I allowed it to\r
+do so, it would absorb my whole nature, my whole soul, my very art\r
+itself. I did not want any external influence in my life. You know\r
+yourself, Harry, how independent I am by nature. I have always been my\r
+own master; had at least always been so, till I met Dorian Gray.\r
+Then--but I don't know how to explain it to you. Something seemed to\r
+tell me that I was on the verge of a terrible crisis in my life. I had\r
+a strange feeling that fate had in store for me exquisite joys and\r
+exquisite sorrows. I grew afraid and turned to quit the room. It was\r
+not conscience that made me do so: it was a sort of cowardice. I take\r
+no credit to myself for trying to escape."\r
+\r
+"Conscience and cowardice are really the same things, Basil.\r
+Conscience is the trade-name of the firm. That is all."\r
+\r
+"I don't believe that, Harry, and I don't believe you do either.\r
+However, whatever was my motive--and it may have been pride, for I used\r
+to be very proud--I certainly struggled to the door. There, of course,\r
+I stumbled against Lady Brandon. 'You are not going to run away so\r
+soon, Mr. Hallward?' she screamed out. You know her curiously shrill\r
+voice?"\r
+\r
+"Yes; she is a peacock in everything but beauty," said Lord Henry,\r
+pulling the daisy to bits with his long nervous fingers.\r
+\r
+"I could not get rid of her. She brought me up to royalties, and\r
+people with stars and garters, and elderly ladies with gigantic tiaras\r
+and parrot noses. She spoke of me as her dearest friend. I had only\r
+met her once before, but she took it into her head to lionize me. I\r
+believe some picture of mine had made a great success at the time, at\r
+least had been chattered about in the penny newspapers, which is the\r
+nineteenth-century standard of immortality. Suddenly I found myself\r
+face to face with the young man whose personality had so strangely\r
+stirred me. We were quite close, almost touching. Our eyes met again.\r
+It was reckless of me, but I asked Lady Brandon to introduce me to him.\r
+Perhaps it was not so reckless, after all. It was simply inevitable.\r
+We would have spoken to each other without any introduction. I am sure\r
+of that. Dorian told me so afterwards. He, too, felt that we were\r
+destined to know each other."\r
+\r
+"And how did Lady Brandon describe this wonderful young man?" asked his\r
+companion. "I know she goes in for giving a rapid _precis_ of all her\r
+guests. I remember her bringing me up to a truculent and red-faced old\r
+gentleman covered all over with orders and ribbons, and hissing into my\r
+ear, in a tragic whisper which must have been perfectly audible to\r
+everybody in the room, the most astounding details. I simply fled. I\r
+like to find out people for myself. But Lady Brandon treats her guests\r
+exactly as an auctioneer treats his goods. She either explains them\r
+entirely away, or tells one everything about them except what one wants\r
+to know."\r
+\r
+"Poor Lady Brandon! You are hard on her, Harry!" said Hallward\r
+listlessly.\r
+\r
+"My dear fellow, she tried to found a _salon_, and only succeeded in\r
+opening a restaurant. How could I admire her? But tell me, what did\r
+she say about Mr. Dorian Gray?"\r
+\r
+"Oh, something like, 'Charming boy--poor dear mother and I absolutely\r
+inseparable. Quite forget what he does--afraid he--doesn't do\r
+anything--oh, yes, plays the piano--or is it the violin, dear Mr.\r
+Gray?' Neither of us could help laughing, and we became friends at\r
+once."\r
+\r
+"Laughter is not at all a bad beginning for a friendship, and it is far\r
+the best ending for one," said the young lord, plucking another daisy.\r
+\r
+Hallward shook his head. "You don't understand what friendship is,\r
+Harry," he murmured--"or what enmity is, for that matter. You like\r
+every one; that is to say, you are indifferent to every one."\r
+\r
+"How horribly unjust of you!" cried Lord Henry, tilting his hat back\r
+and looking up at the little clouds that, like ravelled skeins of\r
+glossy white silk, were drifting across the hollowed turquoise of the\r
+summer sky. "Yes; horribly unjust of you. I make a great difference\r
+between people. I choose my friends for their good looks, my\r
+acquaintances for their good characters, and my enemies for their good\r
+intellects. A man cannot be too careful in the choice of his enemies.\r
+I have not got one who is a fool. They are all men of some\r
+intellectual power, and consequently they all appreciate me. Is that\r
+very vain of me? I think it is rather vain."\r
+\r
+"I should think it was, Harry. But according to your category I must\r
+be merely an acquaintance."\r
+\r
+"My dear old Basil, you are much more than an acquaintance."\r
+\r
+"And much less than a friend. A sort of brother, I suppose?"\r
+\r
+"Oh, brothers! I don't care for brothers. My elder brother won't die,\r
+and my younger brothers seem never to do anything else."\r
+\r
+"Harry!" exclaimed Hallward, frowning.\r
+\r
+"My dear fellow, I am not quite serious. But I can't help detesting my\r
+relations. I suppose it comes from the fact that none of us can stand\r
+other people having the same faults as ourselves. I quite sympathize\r
+with the rage of the English democracy against what they call the vices\r
+of the upper orders. The masses feel that drunkenness, stupidity, and\r
+immorality should be their own special property, and that if any one of\r
+us makes an ass of himself, he is poaching on their preserves. When\r
+poor Southwark got into the divorce court, their indignation was quite\r
+magnificent. And yet I don't suppose that ten per cent of the\r
+proletariat live correctly."\r
+\r
+"I don't agree with a single word that you have said, and, what is\r
+more, Harry, I feel sure you don't either."\r
+\r
+Lord Henry stroked his pointed brown beard and tapped the toe of his\r
+patent-leather boot with a tasselled ebony cane. "How English you are\r
+Basil! That is the second time you have made that observation. If one\r
+puts forward an idea to a true Englishman--always a rash thing to\r
+do--he never dreams of considering whether the idea is right or wrong.\r
+The only thing he considers of any importance is whether one believes\r
+it oneself. Now, the value of an idea has nothing whatsoever to do\r
+with the sincerity of the man who expresses it. Indeed, the\r
+probabilities are that the more insincere the man is, the more purely\r
+intellectual will the idea be, as in that case it will not be coloured\r
+by either his wants, his desires, or his prejudices. However, I don't\r
+propose to discuss politics, sociology, or metaphysics with you. I\r
+like persons better than principles, and I like persons with no\r
+principles better than anything else in the world. Tell me more about\r
+Mr. Dorian Gray. How often do you see him?"\r
+\r
+"Every day. I couldn't be happy if I didn't see him every day. He is\r
+absolutely necessary to me."\r
+\r
+"How extraordinary! I thought you would never care for anything but\r
+your art."\r
+\r
+"He is all my art to me now," said the painter gravely. "I sometimes\r
+think, Harry, that there are only two eras of any importance in the\r
+world's history. The first is the appearance of a new medium for art,\r
+and the second is the appearance of a new personality for art also.\r
+What the invention of oil-painting was to the Venetians, the face of\r
+Antinous was to late Greek sculpture, and the face of Dorian Gray will\r
+some day be to me. It is not merely that I paint from him, draw from\r
+him, sketch from him. Of course, I have done all that. But he is much\r
+more to me than a model or a sitter. I won't tell you that I am\r
+dissatisfied with what I have done of him, or that his beauty is such\r
+that art cannot express it. There is nothing that art cannot express,\r
+and I know that the work I have done, since I met Dorian Gray, is good\r
+work, is the best work of my life. But in some curious way--I wonder\r
+will you understand me?--his personality has suggested to me an\r
+entirely new manner in art, an entirely new mode of style. I see\r
+things differently, I think of them differently. I can now recreate\r
+life in a way that was hidden from me before. 'A dream of form in days\r
+of thought'--who is it who says that? I forget; but it is what Dorian\r
+Gray has been to me. The merely visible presence of this lad--for he\r
+seems to me little more than a lad, though he is really over\r
+twenty--his merely visible presence--ah! I wonder can you realize all\r
+that that means? Unconsciously he defines for me the lines of a fresh\r
+school, a school that is to have in it all the passion of the romantic\r
+spirit, all the perfection of the spirit that is Greek. The harmony of\r
+soul and body--how much that is! We in our madness have separated the\r
+two, and have invented a realism that is vulgar, an ideality that is\r
+void. Harry! if you only knew what Dorian Gray is to me! You remember\r
+that landscape of mine, for which Agnew offered me such a huge price\r
+but which I would not part with? It is one of the best things I have\r
+ever done. And why is it so? Because, while I was painting it, Dorian\r
+Gray sat beside me. Some subtle influence passed from him to me, and\r
+for the first time in my life I saw in the plain woodland the wonder I\r
+had always looked for and always missed."\r
+\r
+"Basil, this is extraordinary! I must see Dorian Gray."\r
+\r
+Hallward got up from the seat and walked up and down the garden. After\r
+some time he came back. "Harry," he said, "Dorian Gray is to me simply\r
+a motive in art. You might see nothing in him. I see everything in\r
+him. He is never more present in my work than when no image of him is\r
+there. He is a suggestion, as I have said, of a new manner. I find\r
+him in the curves of certain lines, in the loveliness and subtleties of\r
+certain colours. That is all."\r
+\r
+"Then why won't you exhibit his portrait?" asked Lord Henry.\r
+\r
+"Because, without intending it, I have put into it some expression of\r
+all this curious artistic idolatry, of which, of course, I have never\r
+cared to speak to him. He knows nothing about it. He shall never know\r
+anything about it. But the world might guess it, and I will not bare\r
+my soul to their shallow prying eyes. My heart shall never be put\r
+under their microscope. There is too much of myself in the thing,\r
+Harry--too much of myself!"\r
+\r
+"Poets are not so scrupulous as you are. They know how useful passion\r
+is for publication. Nowadays a broken heart will run to many editions."\r
+\r
+"I hate them for it," cried Hallward. "An artist should create\r
+beautiful things, but should put nothing of his own life into them. We\r
+live in an age when men treat art as if it were meant to be a form of\r
+autobiography. We have lost the abstract sense of beauty. Some day I\r
+will show the world what it is; and for that reason the world shall\r
+never see my portrait of Dorian Gray."\r
+\r
+"I think you are wrong, Basil, but I won't argue with you. It is only\r
+the intellectually lost who ever argue. Tell me, is Dorian Gray very\r
+fond of you?"\r
+\r
+The painter considered for a few moments. "He likes me," he answered\r
+after a pause; "I know he likes me. Of course I flatter him\r
+dreadfully. I find a strange pleasure in saying things to him that I\r
+know I shall be sorry for having said. As a rule, he is charming to\r
+me, and we sit in the studio and talk of a thousand things. Now and\r
+then, however, he is horribly thoughtless, and seems to take a real\r
+delight in giving me pain. Then I feel, Harry, that I have given away\r
+my whole soul to some one who treats it as if it were a flower to put\r
+in his coat, a bit of decoration to charm his vanity, an ornament for a\r
+summer's day."\r
+\r
+"Days in summer, Basil, are apt to linger," murmured Lord Henry.\r
+"Perhaps you will tire sooner than he will. It is a sad thing to think\r
+of, but there is no doubt that genius lasts longer than beauty. That\r
+accounts for the fact that we all take such pains to over-educate\r
+ourselves. In the wild struggle for existence, we want to have\r
+something that endures, and so we fill our minds with rubbish and\r
+facts, in the silly hope of keeping our place. The thoroughly\r
+well-informed man--that is the modern ideal. And the mind of the\r
+thoroughly well-informed man is a dreadful thing. It is like a\r
+_bric-a-brac_ shop, all monsters and dust, with everything priced above\r
+its proper value. I think you will tire first, all the same. Some day\r
+you will look at your friend, and he will seem to you to be a little\r
+out of drawing, or you won't like his tone of colour, or something.\r
+You will bitterly reproach him in your own heart, and seriously think\r
+that he has behaved very badly to you. The next time he calls, you\r
+will be perfectly cold and indifferent. It will be a great pity, for\r
+it will alter you. What you have told me is quite a romance, a romance\r
+of art one might call it, and the worst of having a romance of any kind\r
+is that it leaves one so unromantic."\r
+\r
+"Harry, don't talk like that. As long as I live, the personality of\r
+Dorian Gray will dominate me. You can't feel what I feel. You change\r
+too often."\r
+\r
+"Ah, my dear Basil, that is exactly why I can feel it. Those who are\r
+faithful know only the trivial side of love: it is the faithless who\r
+know love's tragedies." And Lord Henry struck a light on a dainty\r
+silver case and began to smoke a cigarette with a self-conscious and\r
+satisfied air, as if he had summed up the world in a phrase. There was\r
+a rustle of chirruping sparrows in the green lacquer leaves of the ivy,\r
+and the blue cloud-shadows chased themselves across the grass like\r
+swallows. How pleasant it was in the garden! And how delightful other\r
+people's emotions were!--much more delightful than their ideas, it\r
+seemed to him. One's own soul, and the passions of one's\r
+friends--those were the fascinating things in life. He pictured to\r
+himself with silent amusement the tedious luncheon that he had missed\r
+by staying so long with Basil Hallward. Had he gone to his aunt's, he\r
+would have been sure to have met Lord Goodbody there, and the whole\r
+conversation would have been about the feeding of the poor and the\r
+necessity for model lodging-houses. Each class would have preached the\r
+importance of those virtues, for whose exercise there was no necessity\r
+in their own lives. The rich would have spoken on the value of thrift,\r
+and the idle grown eloquent over the dignity of labour. It was\r
+charming to have escaped all that! As he thought of his aunt, an idea\r
+seemed to strike him. He turned to Hallward and said, "My dear fellow,\r
+I have just remembered."\r
+\r
+"Remembered what, Harry?"\r
+\r
+"Where I heard the name of Dorian Gray."\r
+\r
+"Where was it?" asked Hallward, with a slight frown.\r
+\r
+"Don't look so angry, Basil. It was at my aunt, Lady Agatha's. She\r
+told me she had discovered a wonderful young man who was going to help\r
+her in the East End, and that his name was Dorian Gray. I am bound to\r
+state that she never told me he was good-looking. Women have no\r
+appreciation of good looks; at least, good women have not. She said\r
+that he was very earnest and had a beautiful nature. I at once\r
+pictured to myself a creature with spectacles and lank hair, horribly\r
+freckled, and tramping about on huge feet. I wish I had known it was\r
+your friend."\r
+\r
+"I am very glad you didn't, Harry."\r
+\r
+"Why?"\r
+\r
+"I don't want you to meet him."\r
+\r
+"You don't want me to meet him?"\r
+\r
+"No."\r
+\r
+"Mr. Dorian Gray is in the studio, sir," said the butler, coming into\r
+the garden.\r
+\r
+"You must introduce me now," cried Lord Henry, laughing.\r
+\r
+The painter turned to his servant, who stood blinking in the sunlight.\r
+"Ask Mr. Gray to wait, Parker: I shall be in in a few moments." The\r
+man bowed and went up the walk.\r
+\r
+Then he looked at Lord Henry. "Dorian Gray is my dearest friend," he\r
+said. "He has a simple and a beautiful nature. Your aunt was quite\r
+right in what she said of him. Don't spoil him. Don't try to\r
+influence him. Your influence would be bad. The world is wide, and\r
+has many marvellous people in it. Don't take away from me the one\r
+person who gives to my art whatever charm it possesses: my life as an\r
+artist depends on him. Mind, Harry, I trust you." He spoke very\r
+slowly, and the words seemed wrung out of him almost against his will.\r
+\r
+"What nonsense you talk!" said Lord Henry, smiling, and taking Hallward\r
+by the arm, he almost led him into the house.\r
+\r
+\r
+\r
+CHAPTER 2\r
+\r
+As they entered they saw Dorian Gray. He was seated at the piano, with\r
+his back to them, turning over the pages of a volume of Schumann's\r
+"Forest Scenes." "You must lend me these, Basil," he cried. "I want\r
+to learn them. They are perfectly charming."\r
+\r
+"That entirely depends on how you sit to-day, Dorian."\r
+\r
+"Oh, I am tired of sitting, and I don't want a life-sized portrait of\r
+myself," answered the lad, swinging round on the music-stool in a\r
+wilful, petulant manner. When he caught sight of Lord Henry, a faint\r
+blush coloured his cheeks for a moment, and he started up. "I beg your\r
+pardon, Basil, but I didn't know you had any one with you."\r
+\r
+"This is Lord Henry Wotton, Dorian, an old Oxford friend of mine. I\r
+have just been telling him what a capital sitter you were, and now you\r
+have spoiled everything."\r
+\r
+"You have not spoiled my pleasure in meeting you, Mr. Gray," said Lord\r
+Henry, stepping forward and extending his hand. "My aunt has often\r
+spoken to me about you. You are one of her favourites, and, I am\r
+afraid, one of her victims also."\r
+\r
+"I am in Lady Agatha's black books at present," answered Dorian with a\r
+funny look of penitence. "I promised to go to a club in Whitechapel\r
+with her last Tuesday, and I really forgot all about it. We were to\r
+have played a duet together--three duets, I believe. I don't know what\r
+she will say to me. I am far too frightened to call."\r
+\r
+"Oh, I will make your peace with my aunt. She is quite devoted to you.\r
+And I don't think it really matters about your not being there. The\r
+audience probably thought it was a duet. When Aunt Agatha sits down to\r
+the piano, she makes quite enough noise for two people."\r
+\r
+"That is very horrid to her, and not very nice to me," answered Dorian,\r
+laughing.\r
+\r
+Lord Henry looked at him. Yes, he was certainly wonderfully handsome,\r
+with his finely curved scarlet lips, his frank blue eyes, his crisp\r
+gold hair. There was something in his face that made one trust him at\r
+once. All the candour of youth was there, as well as all youth's\r
+passionate purity. One felt that he had kept himself unspotted from\r
+the world. No wonder Basil Hallward worshipped him.\r
+\r
+"You are too charming to go in for philanthropy, Mr. Gray--far too\r
+charming." And Lord Henry flung himself down on the divan and opened\r
+his cigarette-case.\r
+\r
+The painter had been busy mixing his colours and getting his brushes\r
+ready. He was looking worried, and when he heard Lord Henry's last\r
+remark, he glanced at him, hesitated for a moment, and then said,\r
+"Harry, I want to finish this picture to-day. Would you think it\r
+awfully rude of me if I asked you to go away?"\r
+\r
+Lord Henry smiled and looked at Dorian Gray. "Am I to go, Mr. Gray?"\r
+he asked.\r
+\r
+"Oh, please don't, Lord Henry. I see that Basil is in one of his sulky\r
+moods, and I can't bear him when he sulks. Besides, I want you to tell\r
+me why I should not go in for philanthropy."\r
+\r
+"I don't know that I shall tell you that, Mr. Gray. It is so tedious a\r
+subject that one would have to talk seriously about it. But I\r
+certainly shall not run away, now that you have asked me to stop. You\r
+don't really mind, Basil, do you? You have often told me that you\r
+liked your sitters to have some one to chat to."\r
+\r
+Hallward bit his lip. "If Dorian wishes it, of course you must stay.\r
+Dorian's whims are laws to everybody, except himself."\r
+\r
+Lord Henry took up his hat and gloves. "You are very pressing, Basil,\r
+but I am afraid I must go. I have promised to meet a man at the\r
+Orleans. Good-bye, Mr. Gray. Come and see me some afternoon in Curzon\r
+Street. I am nearly always at home at five o'clock. Write to me when\r
+you are coming. I should be sorry to miss you."\r
+\r
+"Basil," cried Dorian Gray, "if Lord Henry Wotton goes, I shall go,\r
+too. You never open your lips while you are painting, and it is\r
+horribly dull standing on a platform and trying to look pleasant. Ask\r
+him to stay. I insist upon it."\r
+\r
+"Stay, Harry, to oblige Dorian, and to oblige me," said Hallward,\r
+gazing intently at his picture. "It is quite true, I never talk when I\r
+am working, and never listen either, and it must be dreadfully tedious\r
+for my unfortunate sitters. I beg you to stay."\r
+\r
+"But what about my man at the Orleans?"\r
+\r
+The painter laughed. "I don't think there will be any difficulty about\r
+that. Sit down again, Harry. And now, Dorian, get up on the platform,\r
+and don't move about too much, or pay any attention to what Lord Henry\r
+says. He has a very bad influence over all his friends, with the\r
+single exception of myself."\r
+\r
+Dorian Gray stepped up on the dais with the air of a young Greek\r
+martyr, and made a little _moue_ of discontent to Lord Henry, to whom he\r
+had rather taken a fancy. He was so unlike Basil. They made a\r
+delightful contrast. And he had such a beautiful voice. After a few\r
+moments he said to him, "Have you really a very bad influence, Lord\r
+Henry? As bad as Basil says?"\r
+\r
+"There is no such thing as a good influence, Mr. Gray. All influence\r
+is immoral--immoral from the scientific point of view."\r
+\r
+"Why?"\r
+\r
+"Because to influence a person is to give him one's own soul. He does\r
+not think his natural thoughts, or burn with his natural passions. His\r
+virtues are not real to him. His sins, if there are such things as\r
+sins, are borrowed. He becomes an echo of some one else's music, an\r
+actor of a part that has not been written for him. The aim of life is\r
+self-development. To realize one's nature perfectly--that is what each\r
+of us is here for. People are afraid of themselves, nowadays. They\r
+have forgotten the highest of all duties, the duty that one owes to\r
+one's self. Of course, they are charitable. They feed the hungry and\r
+clothe the beggar. But their own souls starve, and are naked. Courage\r
+has gone out of our race. Perhaps we never really had it. The terror\r
+of society, which is the basis of morals, the terror of God, which is\r
+the secret of religion--these are the two things that govern us. And\r
+yet--"\r
+\r
+"Just turn your head a little more to the right, Dorian, like a good\r
+boy," said the painter, deep in his work and conscious only that a look\r
+had come into the lad's face that he had never seen there before.\r
+\r
+"And yet," continued Lord Henry, in his low, musical voice, and with\r
+that graceful wave of the hand that was always so characteristic of\r
+him, and that he had even in his Eton days, "I believe that if one man\r
+were to live out his life fully and completely, were to give form to\r
+every feeling, expression to every thought, reality to every dream--I\r
+believe that the world would gain such a fresh impulse of joy that we\r
+would forget all the maladies of mediaevalism, and return to the\r
+Hellenic ideal--to something finer, richer than the Hellenic ideal, it\r
+may be. But the bravest man amongst us is afraid of himself. The\r
+mutilation of the savage has its tragic survival in the self-denial\r
+that mars our lives. We are punished for our refusals. Every impulse\r
+that we strive to strangle broods in the mind and poisons us. The body\r
+sins once, and has done with its sin, for action is a mode of\r
+purification. Nothing remains then but the recollection of a pleasure,\r
+or the luxury of a regret. The only way to get rid of a temptation is\r
+to yield to it. Resist it, and your soul grows sick with longing for\r
+the things it has forbidden to itself, with desire for what its\r
+monstrous laws have made monstrous and unlawful. It has been said that\r
+the great events of the world take place in the brain. It is in the\r
+brain, and the brain only, that the great sins of the world take place\r
+also. You, Mr. Gray, you yourself, with your rose-red youth and your\r
+rose-white boyhood, you have had passions that have made you afraid,\r
+thoughts that have filled you with terror, day-dreams and sleeping\r
+dreams whose mere memory might stain your cheek with shame--"\r
+\r
+"Stop!" faltered Dorian Gray, "stop! you bewilder me. I don't know\r
+what to say. There is some answer to you, but I cannot find it. Don't\r
+speak. Let me think. Or, rather, let me try not to think."\r
+\r
+For nearly ten minutes he stood there, motionless, with parted lips and\r
+eyes strangely bright. He was dimly conscious that entirely fresh\r
+influences were at work within him. Yet they seemed to him to have\r
+come really from himself. The few words that Basil's friend had said\r
+to him--words spoken by chance, no doubt, and with wilful paradox in\r
+them--had touched some secret chord that had never been touched before,\r
+but that he felt was now vibrating and throbbing to curious pulses.\r
+\r
+Music had stirred him like that. Music had troubled him many times.\r
+But music was not articulate. It was not a new world, but rather\r
+another chaos, that it created in us. Words! Mere words! How\r
+terrible they were! How clear, and vivid, and cruel! One could not\r
+escape from them. And yet what a subtle magic there was in them! They\r
+seemed to be able to give a plastic form to formless things, and to\r
+have a music of their own as sweet as that of viol or of lute. Mere\r
+words! Was there anything so real as words?\r
+\r
+Yes; there had been things in his boyhood that he had not understood.\r
+He understood them now. Life suddenly became fiery-coloured to him.\r
+It seemed to him that he had been walking in fire. Why had he not\r
+known it?\r
+\r
+With his subtle smile, Lord Henry watched him. He knew the precise\r
+psychological moment when to say nothing. He felt intensely\r
+interested. He was amazed at the sudden impression that his words had\r
+produced, and, remembering a book that he had read when he was sixteen,\r
+a book which had revealed to him much that he had not known before, he\r
+wondered whether Dorian Gray was passing through a similar experience.\r
+He had merely shot an arrow into the air. Had it hit the mark? How\r
+fascinating the lad was!\r
+\r
+Hallward painted away with that marvellous bold touch of his, that had\r
+the true refinement and perfect delicacy that in art, at any rate comes\r
+only from strength. He was unconscious of the silence.\r
+\r
+"Basil, I am tired of standing," cried Dorian Gray suddenly. "I must\r
+go out and sit in the garden. The air is stifling here."\r
+\r
+"My dear fellow, I am so sorry. When I am painting, I can't think of\r
+anything else. But you never sat better. You were perfectly still.\r
+And I have caught the effect I wanted--the half-parted lips and the\r
+bright look in the eyes. I don't know what Harry has been saying to\r
+you, but he has certainly made you have the most wonderful expression.\r
+I suppose he has been paying you compliments. You mustn't believe a\r
+word that he says."\r
+\r
+"He has certainly not been paying me compliments. Perhaps that is the\r
+reason that I don't believe anything he has told me."\r
+\r
+"You know you believe it all," said Lord Henry, looking at him with his\r
+dreamy languorous eyes. "I will go out to the garden with you. It is\r
+horribly hot in the studio. Basil, let us have something iced to\r
+drink, something with strawberries in it."\r
+\r
+"Certainly, Harry. Just touch the bell, and when Parker comes I will\r
+tell him what you want. I have got to work up this background, so I\r
+will join you later on. Don't keep Dorian too long. I have never been\r
+in better form for painting than I am to-day. This is going to be my\r
+masterpiece. It is my masterpiece as it stands."\r
+\r
+Lord Henry went out to the garden and found Dorian Gray burying his\r
+face in the great cool lilac-blossoms, feverishly drinking in their\r
+perfume as if it had been wine. He came close to him and put his hand\r
+upon his shoulder. "You are quite right to do that," he murmured.\r
+"Nothing can cure the soul but the senses, just as nothing can cure the\r
+senses but the soul."\r
+\r
+The lad started and drew back. He was bareheaded, and the leaves had\r
+tossed his rebellious curls and tangled all their gilded threads.\r
+There was a look of fear in his eyes, such as people have when they are\r
+suddenly awakened. His finely chiselled nostrils quivered, and some\r
+hidden nerve shook the scarlet of his lips and left them trembling.\r
+\r
+"Yes," continued Lord Henry, "that is one of the great secrets of\r
+life--to cure the soul by means of the senses, and the senses by means\r
+of the soul. You are a wonderful creation. You know more than you\r
+think you know, just as you know less than you want to know."\r
+\r
+Dorian Gray frowned and turned his head away. He could not help liking\r
+the tall, graceful young man who was standing by him. His romantic,\r
+olive-coloured face and worn expression interested him. There was\r
+something in his low languid voice that was absolutely fascinating.\r
+His cool, white, flowerlike hands, even, had a curious charm. They\r
+moved, as he spoke, like music, and seemed to have a language of their\r
+own. But he felt afraid of him, and ashamed of being afraid. Why had\r
+it been left for a stranger to reveal him to himself? He had known\r
+Basil Hallward for months, but the friendship between them had never\r
+altered him. Suddenly there had come some one across his life who\r
+seemed to have disclosed to him life's mystery. And, yet, what was\r
+there to be afraid of? He was not a schoolboy or a girl. It was\r
+absurd to be frightened.\r
+\r
+"Let us go and sit in the shade," said Lord Henry. "Parker has brought\r
+out the drinks, and if you stay any longer in this glare, you will be\r
+quite spoiled, and Basil will never paint you again. You really must\r
+not allow yourself to become sunburnt. It would be unbecoming."\r
+\r
+"What can it matter?" cried Dorian Gray, laughing, as he sat down on\r
+the seat at the end of the garden.\r
+\r
+"It should matter everything to you, Mr. Gray."\r
+\r
+"Why?"\r
+\r
+"Because you have the most marvellous youth, and youth is the one thing\r
+worth having."\r
+\r
+"I don't feel that, Lord Henry."\r
+\r
+"No, you don't feel it now. Some day, when you are old and wrinkled\r
+and ugly, when thought has seared your forehead with its lines, and\r
+passion branded your lips with its hideous fires, you will feel it, you\r
+will feel it terribly. Now, wherever you go, you charm the world.\r
+Will it always be so? ... You have a wonderfully beautiful face, Mr.\r
+Gray. Don't frown. You have. And beauty is a form of genius--is\r
+higher, indeed, than genius, as it needs no explanation. It is of the\r
+great facts of the world, like sunlight, or spring-time, or the\r
+reflection in dark waters of that silver shell we call the moon. It\r
+cannot be questioned. It has its divine right of sovereignty. It\r
+makes princes of those who have it. You smile? Ah! when you have lost\r
+it you won't smile.... People say sometimes that beauty is only\r
+superficial. That may be so, but at least it is not so superficial as\r
+thought is. To me, beauty is the wonder of wonders. It is only\r
+shallow people who do not judge by appearances. The true mystery of\r
+the world is the visible, not the invisible.... Yes, Mr. Gray, the\r
+gods have been good to you. But what the gods give they quickly take\r
+away. You have only a few years in which to live really, perfectly,\r
+and fully. When your youth goes, your beauty will go with it, and then\r
+you will suddenly discover that there are no triumphs left for you, or\r
+have to content yourself with those mean triumphs that the memory of\r
+your past will make more bitter than defeats. Every month as it wanes\r
+brings you nearer to something dreadful. Time is jealous of you, and\r
+wars against your lilies and your roses. You will become sallow, and\r
+hollow-cheeked, and dull-eyed. You will suffer horribly.... Ah!\r
+realize your youth while you have it. Don't squander the gold of your\r
+days, listening to the tedious, trying to improve the hopeless failure,\r
+or giving away your life to the ignorant, the common, and the vulgar.\r
+These are the sickly aims, the false ideals, of our age. Live! Live\r
+the wonderful life that is in you! Let nothing be lost upon you. Be\r
+always searching for new sensations. Be afraid of nothing.... A new\r
+Hedonism--that is what our century wants. You might be its visible\r
+symbol. With your personality there is nothing you could not do. The\r
+world belongs to you for a season.... The moment I met you I saw that\r
+you were quite unconscious of what you really are, of what you really\r
+might be. There was so much in you that charmed me that I felt I must\r
+tell you something about yourself. I thought how tragic it would be if\r
+you were wasted. For there is such a little time that your youth will\r
+last--such a little time. The common hill-flowers wither, but they\r
+blossom again. The laburnum will be as yellow next June as it is now.\r
+In a month there will be purple stars on the clematis, and year after\r
+year the green night of its leaves will hold its purple stars. But we\r
+never get back our youth. The pulse of joy that beats in us at twenty\r
+becomes sluggish. Our limbs fail, our senses rot. We degenerate into\r
+hideous puppets, haunted by the memory of the passions of which we were\r
+too much afraid, and the exquisite temptations that we had not the\r
+courage to yield to. Youth! Youth! There is absolutely nothing in\r
+the world but youth!"\r
+\r
+Dorian Gray listened, open-eyed and wondering. The spray of lilac fell\r
+from his hand upon the gravel. A furry bee came and buzzed round it\r
+for a moment. Then it began to scramble all over the oval stellated\r
+globe of the tiny blossoms. He watched it with that strange interest\r
+in trivial things that we try to develop when things of high import\r
+make us afraid, or when we are stirred by some new emotion for which we\r
+cannot find expression, or when some thought that terrifies us lays\r
+sudden siege to the brain and calls on us to yield. After a time the\r
+bee flew away. He saw it creeping into the stained trumpet of a Tyrian\r
+convolvulus. The flower seemed to quiver, and then swayed gently to\r
+and fro.\r
+\r
+Suddenly the painter appeared at the door of the studio and made\r
+staccato signs for them to come in. They turned to each other and\r
+smiled.\r
+\r
+"I am waiting," he cried. "Do come in. The light is quite perfect,\r
+and you can bring your drinks."\r
+\r
+They rose up and sauntered down the walk together. Two green-and-white\r
+butterflies fluttered past them, and in the pear-tree at the corner of\r
+the garden a thrush began to sing.\r
+\r
+"You are glad you have met me, Mr. Gray," said Lord Henry, looking at\r
+him.\r
+\r
+"Yes, I am glad now. I wonder shall I always be glad?"\r
+\r
+"Always! That is a dreadful word. It makes me shudder when I hear it.\r
+Women are so fond of using it. They spoil every romance by trying to\r
+make it last for ever. It is a meaningless word, too. The only\r
+difference between a caprice and a lifelong passion is that the caprice\r
+lasts a little longer."\r
+\r
+As they entered the studio, Dorian Gray put his hand upon Lord Henry's\r
+arm. "In that case, let our friendship be a caprice," he murmured,\r
+flushing at his own boldness, then stepped up on the platform and\r
+resumed his pose.\r
+\r
+Lord Henry flung himself into a large wicker arm-chair and watched him.\r
+The sweep and dash of the brush on the canvas made the only sound that\r
+broke the stillness, except when, now and then, Hallward stepped back\r
+to look at his work from a distance. In the slanting beams that\r
+streamed through the open doorway the dust danced and was golden. The\r
+heavy scent of the roses seemed to brood over everything.\r
+\r
+After about a quarter of an hour Hallward stopped painting, looked for\r
+a long time at Dorian Gray, and then for a long time at the picture,\r
+biting the end of one of his huge brushes and frowning. "It is quite\r
+finished," he cried at last, and stooping down he wrote his name in\r
+long vermilion letters on the left-hand corner of the canvas.\r
+\r
+Lord Henry came over and examined the picture. It was certainly a\r
+wonderful work of art, and a wonderful likeness as well.\r
+\r
+"My dear fellow, I congratulate you most warmly," he said. "It is the\r
+finest portrait of modern times. Mr. Gray, come over and look at\r
+yourself."\r
+\r
+The lad started, as if awakened from some dream.\r
+\r
+"Is it really finished?" he murmured, stepping down from the platform.\r
+\r
+"Quite finished," said the painter. "And you have sat splendidly\r
+to-day. I am awfully obliged to you."\r
+\r
+"That is entirely due to me," broke in Lord Henry. "Isn't it, Mr.\r
+Gray?"\r
+\r
+Dorian made no answer, but passed listlessly in front of his picture\r
+and turned towards it. When he saw it he drew back, and his cheeks\r
+flushed for a moment with pleasure. A look of joy came into his eyes,\r
+as if he had recognized himself for the first time. He stood there\r
+motionless and in wonder, dimly conscious that Hallward was speaking to\r
+him, but not catching the meaning of his words. The sense of his own\r
+beauty came on him like a revelation. He had never felt it before.\r
+Basil Hallward's compliments had seemed to him to be merely the\r
+charming exaggeration of friendship. He had listened to them, laughed\r
+at them, forgotten them. They had not influenced his nature. Then had\r
+come Lord Henry Wotton with his strange panegyric on youth, his\r
+terrible warning of its brevity. That had stirred him at the time, and\r
+now, as he stood gazing at the shadow of his own loveliness, the full\r
+reality of the description flashed across him. Yes, there would be a\r
+day when his face would be wrinkled and wizen, his eyes dim and\r
+colourless, the grace of his figure broken and deformed. The scarlet\r
+would pass away from his lips and the gold steal from his hair. The\r
+life that was to make his soul would mar his body. He would become\r
+dreadful, hideous, and uncouth.\r
+\r
+As he thought of it, a sharp pang of pain struck through him like a\r
+knife and made each delicate fibre of his nature quiver. His eyes\r
+deepened into amethyst, and across them came a mist of tears. He felt\r
+as if a hand of ice had been laid upon his heart.\r
+\r
+"Don't you like it?" cried Hallward at last, stung a little by the\r
+lad's silence, not understanding what it meant.\r
+\r
+"Of course he likes it," said Lord Henry. "Who wouldn't like it? It\r
+is one of the greatest things in modern art. I will give you anything\r
+you like to ask for it. I must have it."\r
+\r
+"It is not my property, Harry."\r
+\r
+"Whose property is it?"\r
+\r
+"Dorian's, of course," answered the painter.\r
+\r
+"He is a very lucky fellow."\r
+\r
+"How sad it is!" murmured Dorian Gray with his eyes still fixed upon\r
+his own portrait. "How sad it is! I shall grow old, and horrible, and\r
+dreadful. But this picture will remain always young. It will never be\r
+older than this particular day of June.... If it were only the other\r
+way! If it were I who was to be always young, and the picture that was\r
+to grow old! For that--for that--I would give everything! Yes, there\r
+is nothing in the whole world I would not give! I would give my soul\r
+for that!"\r
+\r
+"You would hardly care for such an arrangement, Basil," cried Lord\r
+Henry, laughing. "It would be rather hard lines on your work."\r
+\r
+"I should object very strongly, Harry," said Hallward.\r
+\r
+Dorian Gray turned and looked at him. "I believe you would, Basil.\r
+You like your art better than your friends. I am no more to you than a\r
+green bronze figure. Hardly as much, I dare say."\r
+\r
+The painter stared in amazement. It was so unlike Dorian to speak like\r
+that. What had happened? He seemed quite angry. His face was flushed\r
+and his cheeks burning.\r
+\r
+"Yes," he continued, "I am less to you than your ivory Hermes or your\r
+silver Faun. You will like them always. How long will you like me?\r
+Till I have my first wrinkle, I suppose. I know, now, that when one\r
+loses one's good looks, whatever they may be, one loses everything.\r
+Your picture has taught me that. Lord Henry Wotton is perfectly right.\r
+Youth is the only thing worth having. When I find that I am growing\r
+old, I shall kill myself."\r
+\r
+Hallward turned pale and caught his hand. "Dorian! Dorian!" he cried,\r
+"don't talk like that. I have never had such a friend as you, and I\r
+shall never have such another. You are not jealous of material things,\r
+are you?--you who are finer than any of them!"\r
+\r
+"I am jealous of everything whose beauty does not die. I am jealous of\r
+the portrait you have painted of me. Why should it keep what I must\r
+lose? Every moment that passes takes something from me and gives\r
+something to it. Oh, if it were only the other way! If the picture\r
+could change, and I could be always what I am now! Why did you paint\r
+it? It will mock me some day--mock me horribly!" The hot tears welled\r
+into his eyes; he tore his hand away and, flinging himself on the\r
+divan, he buried his face in the cushions, as though he was praying.\r
+\r
+"This is your doing, Harry," said the painter bitterly.\r
+\r
+Lord Henry shrugged his shoulders. "It is the real Dorian Gray--that\r
+is all."\r
+\r
+"It is not."\r
+\r
+"If it is not, what have I to do with it?"\r
+\r
+"You should have gone away when I asked you," he muttered.\r
+\r
+"I stayed when you asked me," was Lord Henry's answer.\r
+\r
+"Harry, I can't quarrel with my two best friends at once, but between\r
+you both you have made me hate the finest piece of work I have ever\r
+done, and I will destroy it. What is it but canvas and colour? I will\r
+not let it come across our three lives and mar them."\r
+\r
+Dorian Gray lifted his golden head from the pillow, and with pallid\r
+face and tear-stained eyes, looked at him as he walked over to the deal\r
+painting-table that was set beneath the high curtained window. What\r
+was he doing there? His fingers were straying about among the litter\r
+of tin tubes and dry brushes, seeking for something. Yes, it was for\r
+the long palette-knife, with its thin blade of lithe steel. He had\r
+found it at last. He was going to rip up the canvas.\r
+\r
+With a stifled sob the lad leaped from the couch, and, rushing over to\r
+Hallward, tore the knife out of his hand, and flung it to the end of\r
+the studio. "Don't, Basil, don't!" he cried. "It would be murder!"\r
+\r
+"I am glad you appreciate my work at last, Dorian," said the painter\r
+coldly when he had recovered from his surprise. "I never thought you\r
+would."\r
+\r
+"Appreciate it? I am in love with it, Basil. It is part of myself. I\r
+feel that."\r
+\r
+"Well, as soon as you are dry, you shall be varnished, and framed, and\r
+sent home. Then you can do what you like with yourself." And he walked\r
+across the room and rang the bell for tea. "You will have tea, of\r
+course, Dorian? And so will you, Harry? Or do you object to such\r
+simple pleasures?"\r
+\r
+"I adore simple pleasures," said Lord Henry. "They are the last refuge\r
+of the complex. But I don't like scenes, except on the stage. What\r
+absurd fellows you are, both of you! I wonder who it was defined man\r
+as a rational animal. It was the most premature definition ever given.\r
+Man is many things, but he is not rational. I am glad he is not, after\r
+all--though I wish you chaps would not squabble over the picture. You\r
+had much better let me have it, Basil. This silly boy doesn't really\r
+want it, and I really do."\r
+\r
+"If you let any one have it but me, Basil, I shall never forgive you!"\r
+cried Dorian Gray; "and I don't allow people to call me a silly boy."\r
+\r
+"You know the picture is yours, Dorian. I gave it to you before it\r
+existed."\r
+\r
+"And you know you have been a little silly, Mr. Gray, and that you\r
+don't really object to being reminded that you are extremely young."\r
+\r
+"I should have objected very strongly this morning, Lord Henry."\r
+\r
+"Ah! this morning! You have lived since then."\r
+\r
+There came a knock at the door, and the butler entered with a laden\r
+tea-tray and set it down upon a small Japanese table. There was a\r
+rattle of cups and saucers and the hissing of a fluted Georgian urn.\r
+Two globe-shaped china dishes were brought in by a page. Dorian Gray\r
+went over and poured out the tea. The two men sauntered languidly to\r
+the table and examined what was under the covers.\r
+\r
+"Let us go to the theatre to-night," said Lord Henry. "There is sure\r
+to be something on, somewhere. I have promised to dine at White's, but\r
+it is only with an old friend, so I can send him a wire to say that I\r
+am ill, or that I am prevented from coming in consequence of a\r
+subsequent engagement. I think that would be a rather nice excuse: it\r
+would have all the surprise of candour."\r
+\r
+"It is such a bore putting on one's dress-clothes," muttered Hallward.\r
+"And, when one has them on, they are so horrid."\r
+\r
+"Yes," answered Lord Henry dreamily, "the costume of the nineteenth\r
+century is detestable. It is so sombre, so depressing. Sin is the\r
+only real colour-element left in modern life."\r
+\r
+"You really must not say things like that before Dorian, Harry."\r
+\r
+"Before which Dorian? The one who is pouring out tea for us, or the\r
+one in the picture?"\r
+\r
+"Before either."\r
+\r
+"I should like to come to the theatre with you, Lord Henry," said the\r
+lad.\r
+\r
+"Then you shall come; and you will come, too, Basil, won't you?"\r
+\r
+"I can't, really. I would sooner not. I have a lot of work to do."\r
+\r
+"Well, then, you and I will go alone, Mr. Gray."\r
+\r
+"I should like that awfully."\r
+\r
+The painter bit his lip and walked over, cup in hand, to the picture.\r
+"I shall stay with the real Dorian," he said, sadly.\r
+\r
+"Is it the real Dorian?" cried the original of the portrait, strolling\r
+across to him. "Am I really like that?"\r
+\r
+"Yes; you are just like that."\r
+\r
+"How wonderful, Basil!"\r
+\r
+"At least you are like it in appearance. But it will never alter,"\r
+sighed Hallward. "That is something."\r
+\r
+"What a fuss people make about fidelity!" exclaimed Lord Henry. "Why,\r
+even in love it is purely a question for physiology. It has nothing to\r
+do with our own will. Young men want to be faithful, and are not; old\r
+men want to be faithless, and cannot: that is all one can say."\r
+\r
+"Don't go to the theatre to-night, Dorian," said Hallward. "Stop and\r
+dine with me."\r
+\r
+"I can't, Basil."\r
+\r
+"Why?"\r
+\r
+"Because I have promised Lord Henry Wotton to go with him."\r
+\r
+"He won't like you the better for keeping your promises. He always\r
+breaks his own. I beg you not to go."\r
+\r
+Dorian Gray laughed and shook his head.\r
+\r
+"I entreat you."\r
+\r
+The lad hesitated, and looked over at Lord Henry, who was watching them\r
+from the tea-table with an amused smile.\r
+\r
+"I must go, Basil," he answered.\r
+\r
+"Very well," said Hallward, and he went over and laid down his cup on\r
+the tray. "It is rather late, and, as you have to dress, you had\r
+better lose no time. Good-bye, Harry. Good-bye, Dorian. Come and see\r
+me soon. Come to-morrow."\r
+\r
+"Certainly."\r
+\r
+"You won't forget?"\r
+\r
+"No, of course not," cried Dorian.\r
+\r
+"And ... Harry!"\r
+\r
+"Yes, Basil?"\r
+\r
+"Remember what I asked you, when we were in the garden this morning."\r
+\r
+"I have forgotten it."\r
+\r
+"I trust you."\r
+\r
+"I wish I could trust myself," said Lord Henry, laughing. "Come, Mr.\r
+Gray, my hansom is outside, and I can drop you at your own place.\r
+Good-bye, Basil. It has been a most interesting afternoon."\r
+\r
+As the door closed behind them, the painter flung himself down on a\r
+sofa, and a look of pain came into his face.\r
+\r
+\r
+\r
+CHAPTER 3\r
+\r
+At half-past twelve next day Lord Henry Wotton strolled from Curzon\r
+Street over to the Albany to call on his uncle, Lord Fermor, a genial\r
+if somewhat rough-mannered old bachelor, whom the outside world called\r
+selfish because it derived no particular benefit from him, but who was\r
+considered generous by Society as he fed the people who amused him.\r
+His father had been our ambassador at Madrid when Isabella was young\r
+and Prim unthought of, but had retired from the diplomatic service in a\r
+capricious moment of annoyance on not being offered the Embassy at\r
+Paris, a post to which he considered that he was fully entitled by\r
+reason of his birth, his indolence, the good English of his dispatches,\r
+and his inordinate passion for pleasure. The son, who had been his\r
+father's secretary, had resigned along with his chief, somewhat\r
+foolishly as was thought at the time, and on succeeding some months\r
+later to the title, had set himself to the serious study of the great\r
+aristocratic art of doing absolutely nothing. He had two large town\r
+houses, but preferred to live in chambers as it was less trouble, and\r
+took most of his meals at his club. He paid some attention to the\r
+management of his collieries in the Midland counties, excusing himself\r
+for this taint of industry on the ground that the one advantage of\r
+having coal was that it enabled a gentleman to afford the decency of\r
+burning wood on his own hearth. In politics he was a Tory, except when\r
+the Tories were in office, during which period he roundly abused them\r
+for being a pack of Radicals. He was a hero to his valet, who bullied\r
+him, and a terror to most of his relations, whom he bullied in turn.\r
+Only England could have produced him, and he always said that the\r
+country was going to the dogs. His principles were out of date, but\r
+there was a good deal to be said for his prejudices.\r
+\r
+When Lord Henry entered the room, he found his uncle sitting in a rough\r
+shooting-coat, smoking a cheroot and grumbling over _The Times_. "Well,\r
+Harry," said the old gentleman, "what brings you out so early? I\r
+thought you dandies never got up till two, and were not visible till\r
+five."\r
+\r
+"Pure family affection, I assure you, Uncle George. I want to get\r
+something out of you."\r
+\r
+"Money, I suppose," said Lord Fermor, making a wry face. "Well, sit\r
+down and tell me all about it. Young people, nowadays, imagine that\r
+money is everything."\r
+\r
+"Yes," murmured Lord Henry, settling his button-hole in his coat; "and\r
+when they grow older they know it. But I don't want money. It is only\r
+people who pay their bills who want that, Uncle George, and I never pay\r
+mine. Credit is the capital of a younger son, and one lives charmingly\r
+upon it. Besides, I always deal with Dartmoor's tradesmen, and\r
+consequently they never bother me. What I want is information: not\r
+useful information, of course; useless information."\r
+\r
+"Well, I can tell you anything that is in an English Blue Book, Harry,\r
+although those fellows nowadays write a lot of nonsense. When I was in\r
+the Diplomatic, things were much better. But I hear they let them in\r
+now by examination. What can you expect? Examinations, sir, are pure\r
+humbug from beginning to end. If a man is a gentleman, he knows quite\r
+enough, and if he is not a gentleman, whatever he knows is bad for him."\r
+\r
+"Mr. Dorian Gray does not belong to Blue Books, Uncle George," said\r
+Lord Henry languidly.\r
+\r
+"Mr. Dorian Gray? Who is he?" asked Lord Fermor, knitting his bushy\r
+white eyebrows.\r
+\r
+"That is what I have come to learn, Uncle George. Or rather, I know\r
+who he is. He is the last Lord Kelso's grandson. His mother was a\r
+Devereux, Lady Margaret Devereux. I want you to tell me about his\r
+mother. What was she like? Whom did she marry? You have known nearly\r
+everybody in your time, so you might have known her. I am very much\r
+interested in Mr. Gray at present. I have only just met him."\r
+\r
+"Kelso's grandson!" echoed the old gentleman. "Kelso's grandson! ...\r
+Of course.... I knew his mother intimately. I believe I was at her\r
+christening. She was an extraordinarily beautiful girl, Margaret\r
+Devereux, and made all the men frantic by running away with a penniless\r
+young fellow--a mere nobody, sir, a subaltern in a foot regiment, or\r
+something of that kind. Certainly. I remember the whole thing as if\r
+it happened yesterday. The poor chap was killed in a duel at Spa a few\r
+months after the marriage. There was an ugly story about it. They\r
+said Kelso got some rascally adventurer, some Belgian brute, to insult\r
+his son-in-law in public--paid him, sir, to do it, paid him--and that\r
+the fellow spitted his man as if he had been a pigeon. The thing was\r
+hushed up, but, egad, Kelso ate his chop alone at the club for some\r
+time afterwards. He brought his daughter back with him, I was told,\r
+and she never spoke to him again. Oh, yes; it was a bad business. The\r
+girl died, too, died within a year. So she left a son, did she? I had\r
+forgotten that. What sort of boy is he? If he is like his mother, he\r
+must be a good-looking chap."\r
+\r
+"He is very good-looking," assented Lord Henry.\r
+\r
+"I hope he will fall into proper hands," continued the old man. "He\r
+should have a pot of money waiting for him if Kelso did the right thing\r
+by him. His mother had money, too. All the Selby property came to\r
+her, through her grandfather. Her grandfather hated Kelso, thought him\r
+a mean dog. He was, too. Came to Madrid once when I was there. Egad,\r
+I was ashamed of him. The Queen used to ask me about the English noble\r
+who was always quarrelling with the cabmen about their fares. They\r
+made quite a story of it. I didn't dare show my face at Court for a\r
+month. I hope he treated his grandson better than he did the jarvies."\r
+\r
+"I don't know," answered Lord Henry. "I fancy that the boy will be\r
+well off. He is not of age yet. He has Selby, I know. He told me so.\r
+And ... his mother was very beautiful?"\r
+\r
+"Margaret Devereux was one of the loveliest creatures I ever saw,\r
+Harry. What on earth induced her to behave as she did, I never could\r
+understand. She could have married anybody she chose. Carlington was\r
+mad after her. She was romantic, though. All the women of that family\r
+were. The men were a poor lot, but, egad! the women were wonderful.\r
+Carlington went on his knees to her. Told me so himself. She laughed\r
+at him, and there wasn't a girl in London at the time who wasn't after\r
+him. And by the way, Harry, talking about silly marriages, what is\r
+this humbug your father tells me about Dartmoor wanting to marry an\r
+American? Ain't English girls good enough for him?"\r
+\r
+"It is rather fashionable to marry Americans just now, Uncle George."\r
+\r
+"I'll back English women against the world, Harry," said Lord Fermor,\r
+striking the table with his fist.\r
+\r
+"The betting is on the Americans."\r
+\r
+"They don't last, I am told," muttered his uncle.\r
+\r
+"A long engagement exhausts them, but they are capital at a\r
+steeplechase. They take things flying. I don't think Dartmoor has a\r
+chance."\r
+\r
+"Who are her people?" grumbled the old gentleman. "Has she got any?"\r
+\r
+Lord Henry shook his head. "American girls are as clever at concealing\r
+their parents, as English women are at concealing their past," he said,\r
+rising to go.\r
+\r
+"They are pork-packers, I suppose?"\r
+\r
+"I hope so, Uncle George, for Dartmoor's sake. I am told that\r
+pork-packing is the most lucrative profession in America, after\r
+politics."\r
+\r
+"Is she pretty?"\r
+\r
+"She behaves as if she was beautiful. Most American women do. It is\r
+the secret of their charm."\r
+\r
+"Why can't these American women stay in their own country? They are\r
+always telling us that it is the paradise for women."\r
+\r
+"It is. That is the reason why, like Eve, they are so excessively\r
+anxious to get out of it," said Lord Henry. "Good-bye, Uncle George.\r
+I shall be late for lunch, if I stop any longer. Thanks for giving me\r
+the information I wanted. I always like to know everything about my\r
+new friends, and nothing about my old ones."\r
+\r
+"Where are you lunching, Harry?"\r
+\r
+"At Aunt Agatha's. I have asked myself and Mr. Gray. He is her latest\r
+_protege_."\r
+\r
+"Humph! tell your Aunt Agatha, Harry, not to bother me any more with\r
+her charity appeals. I am sick of them. Why, the good woman thinks\r
+that I have nothing to do but to write cheques for her silly fads."\r
+\r
+"All right, Uncle George, I'll tell her, but it won't have any effect.\r
+Philanthropic people lose all sense of humanity. It is their\r
+distinguishing characteristic."\r
+\r
+The old gentleman growled approvingly and rang the bell for his\r
+servant. Lord Henry passed up the low arcade into Burlington Street\r
+and turned his steps in the direction of Berkeley Square.\r
+\r
+So that was the story of Dorian Gray's parentage. Crudely as it had\r
+been told to him, it had yet stirred him by its suggestion of a\r
+strange, almost modern romance. A beautiful woman risking everything\r
+for a mad passion. A few wild weeks of happiness cut short by a\r
+hideous, treacherous crime. Months of voiceless agony, and then a\r
+child born in pain. The mother snatched away by death, the boy left to\r
+solitude and the tyranny of an old and loveless man. Yes; it was an\r
+interesting background. It posed the lad, made him more perfect, as it\r
+were. Behind every exquisite thing that existed, there was something\r
+tragic. Worlds had to be in travail, that the meanest flower might\r
+blow.... And how charming he had been at dinner the night before, as\r
+with startled eyes and lips parted in frightened pleasure he had sat\r
+opposite to him at the club, the red candleshades staining to a richer\r
+rose the wakening wonder of his face. Talking to him was like playing\r
+upon an exquisite violin. He answered to every touch and thrill of the\r
+bow.... There was something terribly enthralling in the exercise of\r
+influence. No other activity was like it. To project one's soul into\r
+some gracious form, and let it tarry there for a moment; to hear one's\r
+own intellectual views echoed back to one with all the added music of\r
+passion and youth; to convey one's temperament into another as though\r
+it were a subtle fluid or a strange perfume: there was a real joy in\r
+that--perhaps the most satisfying joy left to us in an age so limited\r
+and vulgar as our own, an age grossly carnal in its pleasures, and\r
+grossly common in its aims.... He was a marvellous type, too, this lad,\r
+whom by so curious a chance he had met in Basil's studio, or could be\r
+fashioned into a marvellous type, at any rate. Grace was his, and the\r
+white purity of boyhood, and beauty such as old Greek marbles kept for\r
+us. There was nothing that one could not do with him. He could be\r
+made a Titan or a toy. What a pity it was that such beauty was\r
+destined to fade! ... And Basil? From a psychological point of view,\r
+how interesting he was! The new manner in art, the fresh mode of\r
+looking at life, suggested so strangely by the merely visible presence\r
+of one who was unconscious of it all; the silent spirit that dwelt in\r
+dim woodland, and walked unseen in open field, suddenly showing\r
+herself, Dryadlike and not afraid, because in his soul who sought for\r
+her there had been wakened that wonderful vision to which alone are\r
+wonderful things revealed; the mere shapes and patterns of things\r
+becoming, as it were, refined, and gaining a kind of symbolical value,\r
+as though they were themselves patterns of some other and more perfect\r
+form whose shadow they made real: how strange it all was! He\r
+remembered something like it in history. Was it not Plato, that artist\r
+in thought, who had first analyzed it? Was it not Buonarotti who had\r
+carved it in the coloured marbles of a sonnet-sequence? But in our own\r
+century it was strange.... Yes; he would try to be to Dorian Gray\r
+what, without knowing it, the lad was to the painter who had fashioned\r
+the wonderful portrait. He would seek to dominate him--had already,\r
+indeed, half done so. He would make that wonderful spirit his own.\r
+There was something fascinating in this son of love and death.\r
+\r
+Suddenly he stopped and glanced up at the houses. He found that he had\r
+passed his aunt's some distance, and, smiling to himself, turned back.\r
+When he entered the somewhat sombre hall, the butler told him that they\r
+had gone in to lunch. He gave one of the footmen his hat and stick and\r
+passed into the dining-room.\r
+\r
+"Late as usual, Harry," cried his aunt, shaking her head at him.\r
+\r
+He invented a facile excuse, and having taken the vacant seat next to\r
+her, looked round to see who was there. Dorian bowed to him shyly from\r
+the end of the table, a flush of pleasure stealing into his cheek.\r
+Opposite was the Duchess of Harley, a lady of admirable good-nature and\r
+good temper, much liked by every one who knew her, and of those ample\r
+architectural proportions that in women who are not duchesses are\r
+described by contemporary historians as stoutness. Next to her sat, on\r
+her right, Sir Thomas Burdon, a Radical member of Parliament, who\r
+followed his leader in public life and in private life followed the\r
+best cooks, dining with the Tories and thinking with the Liberals, in\r
+accordance with a wise and well-known rule. The post on her left was\r
+occupied by Mr. Erskine of Treadley, an old gentleman of considerable\r
+charm and culture, who had fallen, however, into bad habits of silence,\r
+having, as he explained once to Lady Agatha, said everything that he\r
+had to say before he was thirty. His own neighbour was Mrs. Vandeleur,\r
+one of his aunt's oldest friends, a perfect saint amongst women, but so\r
+dreadfully dowdy that she reminded one of a badly bound hymn-book.\r
+Fortunately for him she had on the other side Lord Faudel, a most\r
+intelligent middle-aged mediocrity, as bald as a ministerial statement\r
+in the House of Commons, with whom she was conversing in that intensely\r
+earnest manner which is the one unpardonable error, as he remarked once\r
+himself, that all really good people fall into, and from which none of\r
+them ever quite escape.\r
+\r
+"We are talking about poor Dartmoor, Lord Henry," cried the duchess,\r
+nodding pleasantly to him across the table. "Do you think he will\r
+really marry this fascinating young person?"\r
+\r
+"I believe she has made up her mind to propose to him, Duchess."\r
+\r
+"How dreadful!" exclaimed Lady Agatha. "Really, some one should\r
+interfere."\r
+\r
+"I am told, on excellent authority, that her father keeps an American\r
+dry-goods store," said Sir Thomas Burdon, looking supercilious.\r
+\r
+"My uncle has already suggested pork-packing, Sir Thomas."\r
+\r
+"Dry-goods! What are American dry-goods?" asked the duchess, raising\r
+her large hands in wonder and accentuating the verb.\r
+\r
+"American novels," answered Lord Henry, helping himself to some quail.\r
+\r
+The duchess looked puzzled.\r
+\r
+"Don't mind him, my dear," whispered Lady Agatha. "He never means\r
+anything that he says."\r
+\r
+"When America was discovered," said the Radical member--and he began to\r
+give some wearisome facts. Like all people who try to exhaust a\r
+subject, he exhausted his listeners. The duchess sighed and exercised\r
+her privilege of interruption. "I wish to goodness it never had been\r
+discovered at all!" she exclaimed. "Really, our girls have no chance\r
+nowadays. It is most unfair."\r
+\r
+"Perhaps, after all, America never has been discovered," said Mr.\r
+Erskine; "I myself would say that it had merely been detected."\r
+\r
+"Oh! but I have seen specimens of the inhabitants," answered the\r
+duchess vaguely. "I must confess that most of them are extremely\r
+pretty. And they dress well, too. They get all their dresses in\r
+Paris. I wish I could afford to do the same."\r
+\r
+"They say that when good Americans die they go to Paris," chuckled Sir\r
+Thomas, who had a large wardrobe of Humour's cast-off clothes.\r
+\r
+"Really! And where do bad Americans go to when they die?" inquired the\r
+duchess.\r
+\r
+"They go to America," murmured Lord Henry.\r
+\r
+Sir Thomas frowned. "I am afraid that your nephew is prejudiced\r
+against that great country," he said to Lady Agatha. "I have travelled\r
+all over it in cars provided by the directors, who, in such matters,\r
+are extremely civil. I assure you that it is an education to visit it."\r
+\r
+"But must we really see Chicago in order to be educated?" asked Mr.\r
+Erskine plaintively. "I don't feel up to the journey."\r
+\r
+Sir Thomas waved his hand. "Mr. Erskine of Treadley has the world on\r
+his shelves. We practical men like to see things, not to read about\r
+them. The Americans are an extremely interesting people. They are\r
+absolutely reasonable. I think that is their distinguishing\r
+characteristic. Yes, Mr. Erskine, an absolutely reasonable people. I\r
+assure you there is no nonsense about the Americans."\r
+\r
+"How dreadful!" cried Lord Henry. "I can stand brute force, but brute\r
+reason is quite unbearable. There is something unfair about its use.\r
+It is hitting below the intellect."\r
+\r
+"I do not understand you," said Sir Thomas, growing rather red.\r
+\r
+"I do, Lord Henry," murmured Mr. Erskine, with a smile.\r
+\r
+"Paradoxes are all very well in their way...." rejoined the baronet.\r
+\r
+"Was that a paradox?" asked Mr. Erskine. "I did not think so. Perhaps\r
+it was. Well, the way of paradoxes is the way of truth. To test\r
+reality we must see it on the tight rope. When the verities become\r
+acrobats, we can judge them."\r
+\r
+"Dear me!" said Lady Agatha, "how you men argue! I am sure I never can\r
+make out what you are talking about. Oh! Harry, I am quite vexed with\r
+you. Why do you try to persuade our nice Mr. Dorian Gray to give up\r
+the East End? I assure you he would be quite invaluable. They would\r
+love his playing."\r
+\r
+"I want him to play to me," cried Lord Henry, smiling, and he looked\r
+down the table and caught a bright answering glance.\r
+\r
+"But they are so unhappy in Whitechapel," continued Lady Agatha.\r
+\r
+"I can sympathize with everything except suffering," said Lord Henry,\r
+shrugging his shoulders. "I cannot sympathize with that. It is too\r
+ugly, too horrible, too distressing. There is something terribly\r
+morbid in the modern sympathy with pain. One should sympathize with\r
+the colour, the beauty, the joy of life. The less said about life's\r
+sores, the better."\r
+\r
+"Still, the East End is a very important problem," remarked Sir Thomas\r
+with a grave shake of the head.\r
+\r
+"Quite so," answered the young lord. "It is the problem of slavery,\r
+and we try to solve it by amusing the slaves."\r
+\r
+The politician looked at him keenly. "What change do you propose,\r
+then?" he asked.\r
+\r
+Lord Henry laughed. "I don't desire to change anything in England\r
+except the weather," he answered. "I am quite content with philosophic\r
+contemplation. But, as the nineteenth century has gone bankrupt\r
+through an over-expenditure of sympathy, I would suggest that we should\r
+appeal to science to put us straight. The advantage of the emotions is\r
+that they lead us astray, and the advantage of science is that it is\r
+not emotional."\r
+\r
+"But we have such grave responsibilities," ventured Mrs. Vandeleur\r
+timidly.\r
+\r
+"Terribly grave," echoed Lady Agatha.\r
+\r
+Lord Henry looked over at Mr. Erskine. "Humanity takes itself too\r
+seriously. It is the world's original sin. If the caveman had known\r
+how to laugh, history would have been different."\r
+\r
+"You are really very comforting," warbled the duchess. "I have always\r
+felt rather guilty when I came to see your dear aunt, for I take no\r
+interest at all in the East End. For the future I shall be able to\r
+look her in the face without a blush."\r
+\r
+"A blush is very becoming, Duchess," remarked Lord Henry.\r
+\r
+"Only when one is young," she answered. "When an old woman like myself\r
+blushes, it is a very bad sign. Ah! Lord Henry, I wish you would tell\r
+me how to become young again."\r
+\r
+He thought for a moment. "Can you remember any great error that you\r
+committed in your early days, Duchess?" he asked, looking at her across\r
+the table.\r
+\r
+"A great many, I fear," she cried.\r
+\r
+"Then commit them over again," he said gravely. "To get back one's\r
+youth, one has merely to repeat one's follies."\r
+\r
+"A delightful theory!" she exclaimed. "I must put it into practice."\r
+\r
+"A dangerous theory!" came from Sir Thomas's tight lips. Lady Agatha\r
+shook her head, but could not help being amused. Mr. Erskine listened.\r
+\r
+"Yes," he continued, "that is one of the great secrets of life.\r
+Nowadays most people die of a sort of creeping common sense, and\r
+discover when it is too late that the only things one never regrets are\r
+one's mistakes."\r
+\r
+A laugh ran round the table.\r
+\r
+He played with the idea and grew wilful; tossed it into the air and\r
+transformed it; let it escape and recaptured it; made it iridescent\r
+with fancy and winged it with paradox. The praise of folly, as he went\r
+on, soared into a philosophy, and philosophy herself became young, and\r
+catching the mad music of pleasure, wearing, one might fancy, her\r
+wine-stained robe and wreath of ivy, danced like a Bacchante over the\r
+hills of life, and mocked the slow Silenus for being sober. Facts fled\r
+before her like frightened forest things. Her white feet trod the huge\r
+press at which wise Omar sits, till the seething grape-juice rose round\r
+her bare limbs in waves of purple bubbles, or crawled in red foam over\r
+the vat's black, dripping, sloping sides. It was an extraordinary\r
+improvisation. He felt that the eyes of Dorian Gray were fixed on him,\r
+and the consciousness that amongst his audience there was one whose\r
+temperament he wished to fascinate seemed to give his wit keenness and\r
+to lend colour to his imagination. He was brilliant, fantastic,\r
+irresponsible. He charmed his listeners out of themselves, and they\r
+followed his pipe, laughing. Dorian Gray never took his gaze off him,\r
+but sat like one under a spell, smiles chasing each other over his lips\r
+and wonder growing grave in his darkening eyes.\r
+\r
+At last, liveried in the costume of the age, reality entered the room\r
+in the shape of a servant to tell the duchess that her carriage was\r
+waiting. She wrung her hands in mock despair. "How annoying!" she\r
+cried. "I must go. I have to call for my husband at the club, to take\r
+him to some absurd meeting at Willis's Rooms, where he is going to be\r
+in the chair. If I am late he is sure to be furious, and I couldn't\r
+have a scene in this bonnet. It is far too fragile. A harsh word\r
+would ruin it. No, I must go, dear Agatha. Good-bye, Lord Henry, you\r
+are quite delightful and dreadfully demoralizing. I am sure I don't\r
+know what to say about your views. You must come and dine with us some\r
+night. Tuesday? Are you disengaged Tuesday?"\r
+\r
+"For you I would throw over anybody, Duchess," said Lord Henry with a\r
+bow.\r
+\r
+"Ah! that is very nice, and very wrong of you," she cried; "so mind you\r
+come"; and she swept out of the room, followed by Lady Agatha and the\r
+other ladies.\r
+\r
+When Lord Henry had sat down again, Mr. Erskine moved round, and taking\r
+a chair close to him, placed his hand upon his arm.\r
+\r
+"You talk books away," he said; "why don't you write one?"\r
+\r
+"I am too fond of reading books to care to write them, Mr. Erskine. I\r
+should like to write a novel certainly, a novel that would be as lovely\r
+as a Persian carpet and as unreal. But there is no literary public in\r
+England for anything except newspapers, primers, and encyclopaedias.\r
+Of all people in the world the English have the least sense of the\r
+beauty of literature."\r
+\r
+"I fear you are right," answered Mr. Erskine. "I myself used to have\r
+literary ambitions, but I gave them up long ago. And now, my dear\r
+young friend, if you will allow me to call you so, may I ask if you\r
+really meant all that you said to us at lunch?"\r
+\r
+"I quite forget what I said," smiled Lord Henry. "Was it all very bad?"\r
+\r
+"Very bad indeed. In fact I consider you extremely dangerous, and if\r
+anything happens to our good duchess, we shall all look on you as being\r
+primarily responsible. But I should like to talk to you about life.\r
+The generation into which I was born was tedious. Some day, when you\r
+are tired of London, come down to Treadley and expound to me your\r
+philosophy of pleasure over some admirable Burgundy I am fortunate\r
+enough to possess."\r
+\r
+"I shall be charmed. A visit to Treadley would be a great privilege.\r
+It has a perfect host, and a perfect library."\r
+\r
+"You will complete it," answered the old gentleman with a courteous\r
+bow. "And now I must bid good-bye to your excellent aunt. I am due at\r
+the Athenaeum. It is the hour when we sleep there."\r
+\r
+"All of you, Mr. Erskine?"\r
+\r
+"Forty of us, in forty arm-chairs. We are practising for an English\r
+Academy of Letters."\r
+\r
+Lord Henry laughed and rose. "I am going to the park," he cried.\r
+\r
+As he was passing out of the door, Dorian Gray touched him on the arm.\r
+"Let me come with you," he murmured.\r
+\r
+"But I thought you had promised Basil Hallward to go and see him,"\r
+answered Lord Henry.\r
+\r
+"I would sooner come with you; yes, I feel I must come with you. Do\r
+let me. And you will promise to talk to me all the time? No one talks\r
+so wonderfully as you do."\r
+\r
+"Ah! I have talked quite enough for to-day," said Lord Henry, smiling.\r
+"All I want now is to look at life. You may come and look at it with\r
+me, if you care to."\r
+\r
+\r
+\r
+CHAPTER 4\r
+\r
+One afternoon, a month later, Dorian Gray was reclining in a luxurious\r
+arm-chair, in the little library of Lord Henry's house in Mayfair. It\r
+was, in its way, a very charming room, with its high panelled\r
+wainscoting of olive-stained oak, its cream-coloured frieze and ceiling\r
+of raised plasterwork, and its brickdust felt carpet strewn with silk,\r
+long-fringed Persian rugs. On a tiny satinwood table stood a statuette\r
+by Clodion, and beside it lay a copy of Les Cent Nouvelles, bound for\r
+Margaret of Valois by Clovis Eve and powdered with the gilt daisies\r
+that Queen had selected for her device. Some large blue china jars and\r
+parrot-tulips were ranged on the mantelshelf, and through the small\r
+leaded panes of the window streamed the apricot-coloured light of a\r
+summer day in London.\r
+\r
+Lord Henry had not yet come in. He was always late on principle, his\r
+principle being that punctuality is the thief of time. So the lad was\r
+looking rather sulky, as with listless fingers he turned over the pages\r
+of an elaborately illustrated edition of Manon Lescaut that he had\r
+found in one of the book-cases. The formal monotonous ticking of the\r
+Louis Quatorze clock annoyed him. Once or twice he thought of going\r
+away.\r
+\r
+At last he heard a step outside, and the door opened. "How late you\r
+are, Harry!" he murmured.\r
+\r
+"I am afraid it is not Harry, Mr. Gray," answered a shrill voice.\r
+\r
+He glanced quickly round and rose to his feet. "I beg your pardon. I\r
+thought--"\r
+\r
+"You thought it was my husband. It is only his wife. You must let me\r
+introduce myself. I know you quite well by your photographs. I think\r
+my husband has got seventeen of them."\r
+\r
+"Not seventeen, Lady Henry?"\r
+\r
+"Well, eighteen, then. And I saw you with him the other night at the\r
+opera." She laughed nervously as she spoke, and watched him with her\r
+vague forget-me-not eyes. She was a curious woman, whose dresses\r
+always looked as if they had been designed in a rage and put on in a\r
+tempest. She was usually in love with somebody, and, as her passion\r
+was never returned, she had kept all her illusions. She tried to look\r
+picturesque, but only succeeded in being untidy. Her name was\r
+Victoria, and she had a perfect mania for going to church.\r
+\r
+"That was at Lohengrin, Lady Henry, I think?"\r
+\r
+"Yes; it was at dear Lohengrin. I like Wagner's music better than\r
+anybody's. It is so loud that one can talk the whole time without other\r
+people hearing what one says. That is a great advantage, don't you\r
+think so, Mr. Gray?"\r
+\r
+The same nervous staccato laugh broke from her thin lips, and her\r
+fingers began to play with a long tortoise-shell paper-knife.\r
+\r
+Dorian smiled and shook his head: "I am afraid I don't think so, Lady\r
+Henry. I never talk during music--at least, during good music. If one\r
+hears bad music, it is one's duty to drown it in conversation."\r
+\r
+"Ah! that is one of Harry's views, isn't it, Mr. Gray? I always hear\r
+Harry's views from his friends. It is the only way I get to know of\r
+them. But you must not think I don't like good music. I adore it, but\r
+I am afraid of it. It makes me too romantic. I have simply worshipped\r
+pianists--two at a time, sometimes, Harry tells me. I don't know what\r
+it is about them. Perhaps it is that they are foreigners. They all\r
+are, ain't they? Even those that are born in England become foreigners\r
+after a time, don't they? It is so clever of them, and such a\r
+compliment to art. Makes it quite cosmopolitan, doesn't it? You have\r
+never been to any of my parties, have you, Mr. Gray? You must come. I\r
+can't afford orchids, but I spare no expense in foreigners. They make\r
+one's rooms look so picturesque. But here is Harry! Harry, I came in\r
+to look for you, to ask you something--I forget what it was--and I\r
+found Mr. Gray here. We have had such a pleasant chat about music. We\r
+have quite the same ideas. No; I think our ideas are quite different.\r
+But he has been most pleasant. I am so glad I've seen him."\r
+\r
+"I am charmed, my love, quite charmed," said Lord Henry, elevating his\r
+dark, crescent-shaped eyebrows and looking at them both with an amused\r
+smile. "So sorry I am late, Dorian. I went to look after a piece of\r
+old brocade in Wardour Street and had to bargain for hours for it.\r
+Nowadays people know the price of everything and the value of nothing."\r
+\r
+"I am afraid I must be going," exclaimed Lady Henry, breaking an\r
+awkward silence with her silly sudden laugh. "I have promised to drive\r
+with the duchess. Good-bye, Mr. Gray. Good-bye, Harry. You are\r
+dining out, I suppose? So am I. Perhaps I shall see you at Lady\r
+Thornbury's."\r
+\r
+"I dare say, my dear," said Lord Henry, shutting the door behind her\r
+as, looking like a bird of paradise that had been out all night in the\r
+rain, she flitted out of the room, leaving a faint odour of\r
+frangipanni. Then he lit a cigarette and flung himself down on the\r
+sofa.\r
+\r
+"Never marry a woman with straw-coloured hair, Dorian," he said after a\r
+few puffs.\r
+\r
+"Why, Harry?"\r
+\r
+"Because they are so sentimental."\r
+\r
+"But I like sentimental people."\r
+\r
+"Never marry at all, Dorian. Men marry because they are tired; women,\r
+because they are curious: both are disappointed."\r
+\r
+"I don't think I am likely to marry, Harry. I am too much in love.\r
+That is one of your aphorisms. I am putting it into practice, as I do\r
+everything that you say."\r
+\r
+"Who are you in love with?" asked Lord Henry after a pause.\r
+\r
+"With an actress," said Dorian Gray, blushing.\r
+\r
+Lord Henry shrugged his shoulders. "That is a rather commonplace\r
+_debut_."\r
+\r
+"You would not say so if you saw her, Harry."\r
+\r
+"Who is she?"\r
+\r
+"Her name is Sibyl Vane."\r
+\r
+"Never heard of her."\r
+\r
+"No one has. People will some day, however. She is a genius."\r
+\r
+"My dear boy, no woman is a genius. Women are a decorative sex. They\r
+never have anything to say, but they say it charmingly. Women\r
+represent the triumph of matter over mind, just as men represent the\r
+triumph of mind over morals."\r
+\r
+"Harry, how can you?"\r
+\r
+"My dear Dorian, it is quite true. I am analysing women at present, so\r
+I ought to know. The subject is not so abstruse as I thought it was.\r
+I find that, ultimately, there are only two kinds of women, the plain\r
+and the coloured. The plain women are very useful. If you want to\r
+gain a reputation for respectability, you have merely to take them down\r
+to supper. The other women are very charming. They commit one\r
+mistake, however. They paint in order to try and look young. Our\r
+grandmothers painted in order to try and talk brilliantly. _Rouge_ and\r
+_esprit_ used to go together. That is all over now. As long as a woman\r
+can look ten years younger than her own daughter, she is perfectly\r
+satisfied. As for conversation, there are only five women in London\r
+worth talking to, and two of these can't be admitted into decent\r
+society. However, tell me about your genius. How long have you known\r
+her?"\r
+\r
+"Ah! Harry, your views terrify me."\r
+\r
+"Never mind that. How long have you known her?"\r
+\r
+"About three weeks."\r
+\r
+"And where did you come across her?"\r
+\r
+"I will tell you, Harry, but you mustn't be unsympathetic about it.\r
+After all, it never would have happened if I had not met you. You\r
+filled me with a wild desire to know everything about life. For days\r
+after I met you, something seemed to throb in my veins. As I lounged\r
+in the park, or strolled down Piccadilly, I used to look at every one\r
+who passed me and wonder, with a mad curiosity, what sort of lives they\r
+led. Some of them fascinated me. Others filled me with terror. There\r
+was an exquisite poison in the air. I had a passion for sensations....\r
+Well, one evening about seven o'clock, I determined to go out in search\r
+of some adventure. I felt that this grey monstrous London of ours,\r
+with its myriads of people, its sordid sinners, and its splendid sins,\r
+as you once phrased it, must have something in store for me. I fancied\r
+a thousand things. The mere danger gave me a sense of delight. I\r
+remembered what you had said to me on that wonderful evening when we\r
+first dined together, about the search for beauty being the real secret\r
+of life. I don't know what I expected, but I went out and wandered\r
+eastward, soon losing my way in a labyrinth of grimy streets and black\r
+grassless squares. About half-past eight I passed by an absurd little\r
+theatre, with great flaring gas-jets and gaudy play-bills. A hideous\r
+Jew, in the most amazing waistcoat I ever beheld in my life, was\r
+standing at the entrance, smoking a vile cigar. He had greasy\r
+ringlets, and an enormous diamond blazed in the centre of a soiled\r
+shirt. 'Have a box, my Lord?' he said, when he saw me, and he took off\r
+his hat with an air of gorgeous servility. There was something about\r
+him, Harry, that amused me. He was such a monster. You will laugh at\r
+me, I know, but I really went in and paid a whole guinea for the\r
+stage-box. To the present day I can't make out why I did so; and yet if\r
+I hadn't--my dear Harry, if I hadn't--I should have missed the greatest\r
+romance of my life. I see you are laughing. It is horrid of you!"\r
+\r
+"I am not laughing, Dorian; at least I am not laughing at you. But you\r
+should not say the greatest romance of your life. You should say the\r
+first romance of your life. You will always be loved, and you will\r
+always be in love with love. A _grande passion_ is the privilege of\r
+people who have nothing to do. That is the one use of the idle classes\r
+of a country. Don't be afraid. There are exquisite things in store\r
+for you. This is merely the beginning."\r
+\r
+"Do you think my nature so shallow?" cried Dorian Gray angrily.\r
+\r
+"No; I think your nature so deep."\r
+\r
+"How do you mean?"\r
+\r
+"My dear boy, the people who love only once in their lives are really\r
+the shallow people. What they call their loyalty, and their fidelity,\r
+I call either the lethargy of custom or their lack of imagination.\r
+Faithfulness is to the emotional life what consistency is to the life\r
+of the intellect--simply a confession of failure. Faithfulness! I\r
+must analyse it some day. The passion for property is in it. There\r
+are many things that we would throw away if we were not afraid that\r
+others might pick them up. But I don't want to interrupt you. Go on\r
+with your story."\r
+\r
+"Well, I found myself seated in a horrid little private box, with a\r
+vulgar drop-scene staring me in the face. I looked out from behind the\r
+curtain and surveyed the house. It was a tawdry affair, all Cupids and\r
+cornucopias, like a third-rate wedding-cake. The gallery and pit were\r
+fairly full, but the two rows of dingy stalls were quite empty, and\r
+there was hardly a person in what I suppose they called the\r
+dress-circle. Women went about with oranges and ginger-beer, and there\r
+was a terrible consumption of nuts going on."\r
+\r
+"It must have been just like the palmy days of the British drama."\r
+\r
+"Just like, I should fancy, and very depressing. I began to wonder\r
+what on earth I should do when I caught sight of the play-bill. What\r
+do you think the play was, Harry?"\r
+\r
+"I should think 'The Idiot Boy', or 'Dumb but Innocent'. Our fathers\r
+used to like that sort of piece, I believe. The longer I live, Dorian,\r
+the more keenly I feel that whatever was good enough for our fathers is\r
+not good enough for us. In art, as in politics, _les grandperes ont\r
+toujours tort_."\r
+\r
+"This play was good enough for us, Harry. It was Romeo and Juliet. I\r
+must admit that I was rather annoyed at the idea of seeing Shakespeare\r
+done in such a wretched hole of a place. Still, I felt interested, in\r
+a sort of way. At any rate, I determined to wait for the first act.\r
+There was a dreadful orchestra, presided over by a young Hebrew who sat\r
+at a cracked piano, that nearly drove me away, but at last the\r
+drop-scene was drawn up and the play began. Romeo was a stout elderly\r
+gentleman, with corked eyebrows, a husky tragedy voice, and a figure\r
+like a beer-barrel. Mercutio was almost as bad. He was played by the\r
+low-comedian, who had introduced gags of his own and was on most\r
+friendly terms with the pit. They were both as grotesque as the\r
+scenery, and that looked as if it had come out of a country-booth. But\r
+Juliet! Harry, imagine a girl, hardly seventeen years of age, with a\r
+little, flowerlike face, a small Greek head with plaited coils of\r
+dark-brown hair, eyes that were violet wells of passion, lips that were\r
+like the petals of a rose. She was the loveliest thing I had ever seen\r
+in my life. You said to me once that pathos left you unmoved, but that\r
+beauty, mere beauty, could fill your eyes with tears. I tell you,\r
+Harry, I could hardly see this girl for the mist of tears that came\r
+across me. And her voice--I never heard such a voice. It was very low\r
+at first, with deep mellow notes that seemed to fall singly upon one's\r
+ear. Then it became a little louder, and sounded like a flute or a\r
+distant hautboy. In the garden-scene it had all the tremulous ecstasy\r
+that one hears just before dawn when nightingales are singing. There\r
+were moments, later on, when it had the wild passion of violins. You\r
+know how a voice can stir one. Your voice and the voice of Sibyl Vane\r
+are two things that I shall never forget. When I close my eyes, I hear\r
+them, and each of them says something different. I don't know which to\r
+follow. Why should I not love her? Harry, I do love her. She is\r
+everything to me in life. Night after night I go to see her play. One\r
+evening she is Rosalind, and the next evening she is Imogen. I have\r
+seen her die in the gloom of an Italian tomb, sucking the poison from\r
+her lover's lips. I have watched her wandering through the forest of\r
+Arden, disguised as a pretty boy in hose and doublet and dainty cap.\r
+She has been mad, and has come into the presence of a guilty king, and\r
+given him rue to wear and bitter herbs to taste of. She has been\r
+innocent, and the black hands of jealousy have crushed her reedlike\r
+throat. I have seen her in every age and in every costume. Ordinary\r
+women never appeal to one's imagination. They are limited to their\r
+century. No glamour ever transfigures them. One knows their minds as\r
+easily as one knows their bonnets. One can always find them. There is\r
+no mystery in any of them. They ride in the park in the morning and\r
+chatter at tea-parties in the afternoon. They have their stereotyped\r
+smile and their fashionable manner. They are quite obvious. But an\r
+actress! How different an actress is! Harry! why didn't you tell me\r
+that the only thing worth loving is an actress?"\r
+\r
+"Because I have loved so many of them, Dorian."\r
+\r
+"Oh, yes, horrid people with dyed hair and painted faces."\r
+\r
+"Don't run down dyed hair and painted faces. There is an extraordinary\r
+charm in them, sometimes," said Lord Henry.\r
+\r
+"I wish now I had not told you about Sibyl Vane."\r
+\r
+"You could not have helped telling me, Dorian. All through your life\r
+you will tell me everything you do."\r
+\r
+"Yes, Harry, I believe that is true. I cannot help telling you things.\r
+You have a curious influence over me. If I ever did a crime, I would\r
+come and confess it to you. You would understand me."\r
+\r
+"People like you--the wilful sunbeams of life--don't commit crimes,\r
+Dorian. But I am much obliged for the compliment, all the same. And\r
+now tell me--reach me the matches, like a good boy--thanks--what are\r
+your actual relations with Sibyl Vane?"\r
+\r
+Dorian Gray leaped to his feet, with flushed cheeks and burning eyes.\r
+"Harry! Sibyl Vane is sacred!"\r
+\r
+"It is only the sacred things that are worth touching, Dorian," said\r
+Lord Henry, with a strange touch of pathos in his voice. "But why\r
+should you be annoyed? I suppose she will belong to you some day.\r
+When one is in love, one always begins by deceiving one's self, and one\r
+always ends by deceiving others. That is what the world calls a\r
+romance. You know her, at any rate, I suppose?"\r
+\r
+"Of course I know her. On the first night I was at the theatre, the\r
+horrid old Jew came round to the box after the performance was over and\r
+offered to take me behind the scenes and introduce me to her. I was\r
+furious with him, and told him that Juliet had been dead for hundreds\r
+of years and that her body was lying in a marble tomb in Verona. I\r
+think, from his blank look of amazement, that he was under the\r
+impression that I had taken too much champagne, or something."\r
+\r
+"I am not surprised."\r
+\r
+"Then he asked me if I wrote for any of the newspapers. I told him I\r
+never even read them. He seemed terribly disappointed at that, and\r
+confided to me that all the dramatic critics were in a conspiracy\r
+against him, and that they were every one of them to be bought."\r
+\r
+"I should not wonder if he was quite right there. But, on the other\r
+hand, judging from their appearance, most of them cannot be at all\r
+expensive."\r
+\r
+"Well, he seemed to think they were beyond his means," laughed Dorian.\r
+"By this time, however, the lights were being put out in the theatre,\r
+and I had to go. He wanted me to try some cigars that he strongly\r
+recommended. I declined. The next night, of course, I arrived at the\r
+place again. When he saw me, he made me a low bow and assured me that\r
+I was a munificent patron of art. He was a most offensive brute,\r
+though he had an extraordinary passion for Shakespeare. He told me\r
+once, with an air of pride, that his five bankruptcies were entirely\r
+due to 'The Bard,' as he insisted on calling him. He seemed to think\r
+it a distinction."\r
+\r
+"It was a distinction, my dear Dorian--a great distinction. Most\r
+people become bankrupt through having invested too heavily in the prose\r
+of life. To have ruined one's self over poetry is an honour. But when\r
+did you first speak to Miss Sibyl Vane?"\r
+\r
+"The third night. She had been playing Rosalind. I could not help\r
+going round. I had thrown her some flowers, and she had looked at\r
+me--at least I fancied that she had. The old Jew was persistent. He\r
+seemed determined to take me behind, so I consented. It was curious my\r
+not wanting to know her, wasn't it?"\r
+\r
+"No; I don't think so."\r
+\r
+"My dear Harry, why?"\r
+\r
+"I will tell you some other time. Now I want to know about the girl."\r
+\r
+"Sibyl? Oh, she was so shy and so gentle. There is something of a\r
+child about her. Her eyes opened wide in exquisite wonder when I told\r
+her what I thought of her performance, and she seemed quite unconscious\r
+of her power. I think we were both rather nervous. The old Jew stood\r
+grinning at the doorway of the dusty greenroom, making elaborate\r
+speeches about us both, while we stood looking at each other like\r
+children. He would insist on calling me 'My Lord,' so I had to assure\r
+Sibyl that I was not anything of the kind. She said quite simply to\r
+me, 'You look more like a prince. I must call you Prince Charming.'"\r
+\r
+"Upon my word, Dorian, Miss Sibyl knows how to pay compliments."\r
+\r
+"You don't understand her, Harry. She regarded me merely as a person\r
+in a play. She knows nothing of life. She lives with her mother, a\r
+faded tired woman who played Lady Capulet in a sort of magenta\r
+dressing-wrapper on the first night, and looks as if she had seen\r
+better days."\r
+\r
+"I know that look. It depresses me," murmured Lord Henry, examining\r
+his rings.\r
+\r
+"The Jew wanted to tell me her history, but I said it did not interest\r
+me."\r
+\r
+"You were quite right. There is always something infinitely mean about\r
+other people's tragedies."\r
+\r
+"Sibyl is the only thing I care about. What is it to me where she came\r
+from? From her little head to her little feet, she is absolutely and\r
+entirely divine. Every night of my life I go to see her act, and every\r
+night she is more marvellous."\r
+\r
+"That is the reason, I suppose, that you never dine with me now. I\r
+thought you must have some curious romance on hand. You have; but it\r
+is not quite what I expected."\r
+\r
+"My dear Harry, we either lunch or sup together every day, and I have\r
+been to the opera with you several times," said Dorian, opening his\r
+blue eyes in wonder.\r
+\r
+"You always come dreadfully late."\r
+\r
+"Well, I can't help going to see Sibyl play," he cried, "even if it is\r
+only for a single act. I get hungry for her presence; and when I think\r
+of the wonderful soul that is hidden away in that little ivory body, I\r
+am filled with awe."\r
+\r
+"You can dine with me to-night, Dorian, can't you?"\r
+\r
+He shook his head. "To-night she is Imogen," he answered, "and\r
+to-morrow night she will be Juliet."\r
+\r
+"When is she Sibyl Vane?"\r
+\r
+"Never."\r
+\r
+"I congratulate you."\r
+\r
+"How horrid you are! She is all the great heroines of the world in\r
+one. She is more than an individual. You laugh, but I tell you she\r
+has genius. I love her, and I must make her love me. You, who know\r
+all the secrets of life, tell me how to charm Sibyl Vane to love me! I\r
+want to make Romeo jealous. I want the dead lovers of the world to\r
+hear our laughter and grow sad. I want a breath of our passion to stir\r
+their dust into consciousness, to wake their ashes into pain. My God,\r
+Harry, how I worship her!" He was walking up and down the room as he\r
+spoke. Hectic spots of red burned on his cheeks. He was terribly\r
+excited.\r
+\r
+Lord Henry watched him with a subtle sense of pleasure. How different\r
+he was now from the shy frightened boy he had met in Basil Hallward's\r
+studio! His nature had developed like a flower, had borne blossoms of\r
+scarlet flame. Out of its secret hiding-place had crept his soul, and\r
+desire had come to meet it on the way.\r
+\r
+"And what do you propose to do?" said Lord Henry at last.\r
+\r
+"I want you and Basil to come with me some night and see her act. I\r
+have not the slightest fear of the result. You are certain to\r
+acknowledge her genius. Then we must get her out of the Jew's hands.\r
+She is bound to him for three years--at least for two years and eight\r
+months--from the present time. I shall have to pay him something, of\r
+course. When all that is settled, I shall take a West End theatre and\r
+bring her out properly. She will make the world as mad as she has made\r
+me."\r
+\r
+"That would be impossible, my dear boy."\r
+\r
+"Yes, she will. She has not merely art, consummate art-instinct, in\r
+her, but she has personality also; and you have often told me that it\r
+is personalities, not principles, that move the age."\r
+\r
+"Well, what night shall we go?"\r
+\r
+"Let me see. To-day is Tuesday. Let us fix to-morrow. She plays\r
+Juliet to-morrow."\r
+\r
+"All right. The Bristol at eight o'clock; and I will get Basil."\r
+\r
+"Not eight, Harry, please. Half-past six. We must be there before the\r
+curtain rises. You must see her in the first act, where she meets\r
+Romeo."\r
+\r
+"Half-past six! What an hour! It will be like having a meat-tea, or\r
+reading an English novel. It must be seven. No gentleman dines before\r
+seven. Shall you see Basil between this and then? Or shall I write to\r
+him?"\r
+\r
+"Dear Basil! I have not laid eyes on him for a week. It is rather\r
+horrid of me, as he has sent me my portrait in the most wonderful\r
+frame, specially designed by himself, and, though I am a little jealous\r
+of the picture for being a whole month younger than I am, I must admit\r
+that I delight in it. Perhaps you had better write to him. I don't\r
+want to see him alone. He says things that annoy me. He gives me good\r
+advice."\r
+\r
+Lord Henry smiled. "People are very fond of giving away what they need\r
+most themselves. It is what I call the depth of generosity."\r
+\r
+"Oh, Basil is the best of fellows, but he seems to me to be just a bit\r
+of a Philistine. Since I have known you, Harry, I have discovered\r
+that."\r
+\r
+"Basil, my dear boy, puts everything that is charming in him into his\r
+work. The consequence is that he has nothing left for life but his\r
+prejudices, his principles, and his common sense. The only artists I\r
+have ever known who are personally delightful are bad artists. Good\r
+artists exist simply in what they make, and consequently are perfectly\r
+uninteresting in what they are. A great poet, a really great poet, is\r
+the most unpoetical of all creatures. But inferior poets are\r
+absolutely fascinating. The worse their rhymes are, the more\r
+picturesque they look. The mere fact of having published a book of\r
+second-rate sonnets makes a man quite irresistible. He lives the\r
+poetry that he cannot write. The others write the poetry that they\r
+dare not realize."\r
+\r
+"I wonder is that really so, Harry?" said Dorian Gray, putting some\r
+perfume on his handkerchief out of a large, gold-topped bottle that\r
+stood on the table. "It must be, if you say it. And now I am off.\r
+Imogen is waiting for me. Don't forget about to-morrow. Good-bye."\r
+\r
+As he left the room, Lord Henry's heavy eyelids drooped, and he began\r
+to think. Certainly few people had ever interested him so much as\r
+Dorian Gray, and yet the lad's mad adoration of some one else caused\r
+him not the slightest pang of annoyance or jealousy. He was pleased by\r
+it. It made him a more interesting study. He had been always\r
+enthralled by the methods of natural science, but the ordinary\r
+subject-matter of that science had seemed to him trivial and of no\r
+import. And so he had begun by vivisecting himself, as he had ended by\r
+vivisecting others. Human life--that appeared to him the one thing\r
+worth investigating. Compared to it there was nothing else of any\r
+value. It was true that as one watched life in its curious crucible of\r
+pain and pleasure, one could not wear over one's face a mask of glass,\r
+nor keep the sulphurous fumes from troubling the brain and making the\r
+imagination turbid with monstrous fancies and misshapen dreams. There\r
+were poisons so subtle that to know their properties one had to sicken\r
+of them. There were maladies so strange that one had to pass through\r
+them if one sought to understand their nature. And, yet, what a great\r
+reward one received! How wonderful the whole world became to one! To\r
+note the curious hard logic of passion, and the emotional coloured life\r
+of the intellect--to observe where they met, and where they separated,\r
+at what point they were in unison, and at what point they were at\r
+discord--there was a delight in that! What matter what the cost was?\r
+One could never pay too high a price for any sensation.\r
+\r
+He was conscious--and the thought brought a gleam of pleasure into his\r
+brown agate eyes--that it was through certain words of his, musical\r
+words said with musical utterance, that Dorian Gray's soul had turned\r
+to this white girl and bowed in worship before her. To a large extent\r
+the lad was his own creation. He had made him premature. That was\r
+something. Ordinary people waited till life disclosed to them its\r
+secrets, but to the few, to the elect, the mysteries of life were\r
+revealed before the veil was drawn away. Sometimes this was the effect\r
+of art, and chiefly of the art of literature, which dealt immediately\r
+with the passions and the intellect. But now and then a complex\r
+personality took the place and assumed the office of art, was indeed,\r
+in its way, a real work of art, life having its elaborate masterpieces,\r
+just as poetry has, or sculpture, or painting.\r
+\r
+Yes, the lad was premature. He was gathering his harvest while it was\r
+yet spring. The pulse and passion of youth were in him, but he was\r
+becoming self-conscious. It was delightful to watch him. With his\r
+beautiful face, and his beautiful soul, he was a thing to wonder at.\r
+It was no matter how it all ended, or was destined to end. He was like\r
+one of those gracious figures in a pageant or a play, whose joys seem\r
+to be remote from one, but whose sorrows stir one's sense of beauty,\r
+and whose wounds are like red roses.\r
+\r
+Soul and body, body and soul--how mysterious they were! There was\r
+animalism in the soul, and the body had its moments of spirituality.\r
+The senses could refine, and the intellect could degrade. Who could\r
+say where the fleshly impulse ceased, or the psychical impulse began?\r
+How shallow were the arbitrary definitions of ordinary psychologists!\r
+And yet how difficult to decide between the claims of the various\r
+schools! Was the soul a shadow seated in the house of sin? Or was the\r
+body really in the soul, as Giordano Bruno thought? The separation of\r
+spirit from matter was a mystery, and the union of spirit with matter\r
+was a mystery also.\r
+\r
+He began to wonder whether we could ever make psychology so absolute a\r
+science that each little spring of life would be revealed to us. As it\r
+was, we always misunderstood ourselves and rarely understood others.\r
+Experience was of no ethical value. It was merely the name men gave to\r
+their mistakes. Moralists had, as a rule, regarded it as a mode of\r
+warning, had claimed for it a certain ethical efficacy in the formation\r
+of character, had praised it as something that taught us what to follow\r
+and showed us what to avoid. But there was no motive power in\r
+experience. It was as little of an active cause as conscience itself.\r
+All that it really demonstrated was that our future would be the same\r
+as our past, and that the sin we had done once, and with loathing, we\r
+would do many times, and with joy.\r
+\r
+It was clear to him that the experimental method was the only method by\r
+which one could arrive at any scientific analysis of the passions; and\r
+certainly Dorian Gray was a subject made to his hand, and seemed to\r
+promise rich and fruitful results. His sudden mad love for Sibyl Vane\r
+was a psychological phenomenon of no small interest. There was no\r
+doubt that curiosity had much to do with it, curiosity and the desire\r
+for new experiences, yet it was not a simple, but rather a very complex\r
+passion. What there was in it of the purely sensuous instinct of\r
+boyhood had been transformed by the workings of the imagination,\r
+changed into something that seemed to the lad himself to be remote from\r
+sense, and was for that very reason all the more dangerous. It was the\r
+passions about whose origin we deceived ourselves that tyrannized most\r
+strongly over us. Our weakest motives were those of whose nature we\r
+were conscious. It often happened that when we thought we were\r
+experimenting on others we were really experimenting on ourselves.\r
+\r
+While Lord Henry sat dreaming on these things, a knock came to the\r
+door, and his valet entered and reminded him it was time to dress for\r
+dinner. He got up and looked out into the street. The sunset had\r
+smitten into scarlet gold the upper windows of the houses opposite.\r
+The panes glowed like plates of heated metal. The sky above was like a\r
+faded rose. He thought of his friend's young fiery-coloured life and\r
+wondered how it was all going to end.\r
+\r
+When he arrived home, about half-past twelve o'clock, he saw a telegram\r
+lying on the hall table. He opened it and found it was from Dorian\r
+Gray. It was to tell him that he was engaged to be married to Sibyl\r
+Vane.\r
+\r
+\r
+\r
+CHAPTER 5\r
+\r
+"Mother, Mother, I am so happy!" whispered the girl, burying her face\r
+in the lap of the faded, tired-looking woman who, with back turned to\r
+the shrill intrusive light, was sitting in the one arm-chair that their\r
+dingy sitting-room contained. "I am so happy!" she repeated, "and you\r
+must be happy, too!"\r
+\r
+Mrs. Vane winced and put her thin, bismuth-whitened hands on her\r
+daughter's head. "Happy!" she echoed, "I am only happy, Sibyl, when I\r
+see you act. You must not think of anything but your acting. Mr.\r
+Isaacs has been very good to us, and we owe him money."\r
+\r
+The girl looked up and pouted. "Money, Mother?" she cried, "what does\r
+money matter? Love is more than money."\r
+\r
+"Mr. Isaacs has advanced us fifty pounds to pay off our debts and to\r
+get a proper outfit for James. You must not forget that, Sibyl. Fifty\r
+pounds is a very large sum. Mr. Isaacs has been most considerate."\r
+\r
+"He is not a gentleman, Mother, and I hate the way he talks to me,"\r
+said the girl, rising to her feet and going over to the window.\r
+\r
+"I don't know how we could manage without him," answered the elder\r
+woman querulously.\r
+\r
+Sibyl Vane tossed her head and laughed. "We don't want him any more,\r
+Mother. Prince Charming rules life for us now." Then she paused. A\r
+rose shook in her blood and shadowed her cheeks. Quick breath parted\r
+the petals of her lips. They trembled. Some southern wind of passion\r
+swept over her and stirred the dainty folds of her dress. "I love\r
+him," she said simply.\r
+\r
+"Foolish child! foolish child!" was the parrot-phrase flung in answer.\r
+The waving of crooked, false-jewelled fingers gave grotesqueness to the\r
+words.\r
+\r
+The girl laughed again. The joy of a caged bird was in her voice. Her\r
+eyes caught the melody and echoed it in radiance, then closed for a\r
+moment, as though to hide their secret. When they opened, the mist of\r
+a dream had passed across them.\r
+\r
+Thin-lipped wisdom spoke at her from the worn chair, hinted at\r
+prudence, quoted from that book of cowardice whose author apes the name\r
+of common sense. She did not listen. She was free in her prison of\r
+passion. Her prince, Prince Charming, was with her. She had called on\r
+memory to remake him. She had sent her soul to search for him, and it\r
+had brought him back. His kiss burned again upon her mouth. Her\r
+eyelids were warm with his breath.\r
+\r
+Then wisdom altered its method and spoke of espial and discovery. This\r
+young man might be rich. If so, marriage should be thought of.\r
+Against the shell of her ear broke the waves of worldly cunning. The\r
+arrows of craft shot by her. She saw the thin lips moving, and smiled.\r
+\r
+Suddenly she felt the need to speak. The wordy silence troubled her.\r
+"Mother, Mother," she cried, "why does he love me so much? I know why\r
+I love him. I love him because he is like what love himself should be.\r
+But what does he see in me? I am not worthy of him. And yet--why, I\r
+cannot tell--though I feel so much beneath him, I don't feel humble. I\r
+feel proud, terribly proud. Mother, did you love my father as I love\r
+Prince Charming?"\r
+\r
+The elder woman grew pale beneath the coarse powder that daubed her\r
+cheeks, and her dry lips twitched with a spasm of pain. Sybil rushed\r
+to her, flung her arms round her neck, and kissed her. "Forgive me,\r
+Mother. I know it pains you to talk about our father. But it only\r
+pains you because you loved him so much. Don't look so sad. I am as\r
+happy to-day as you were twenty years ago. Ah! let me be happy for\r
+ever!"\r
+\r
+"My child, you are far too young to think of falling in love. Besides,\r
+what do you know of this young man? You don't even know his name. The\r
+whole thing is most inconvenient, and really, when James is going away\r
+to Australia, and I have so much to think of, I must say that you\r
+should have shown more consideration. However, as I said before, if he\r
+is rich ..."\r
+\r
+"Ah! Mother, Mother, let me be happy!"\r
+\r
+Mrs. Vane glanced at her, and with one of those false theatrical\r
+gestures that so often become a mode of second nature to a\r
+stage-player, clasped her in her arms. At this moment, the door opened\r
+and a young lad with rough brown hair came into the room. He was\r
+thick-set of figure, and his hands and feet were large and somewhat\r
+clumsy in movement. He was not so finely bred as his sister. One\r
+would hardly have guessed the close relationship that existed between\r
+them. Mrs. Vane fixed her eyes on him and intensified her smile. She\r
+mentally elevated her son to the dignity of an audience. She felt sure\r
+that the _tableau_ was interesting.\r
+\r
+"You might keep some of your kisses for me, Sibyl, I think," said the\r
+lad with a good-natured grumble.\r
+\r
+"Ah! but you don't like being kissed, Jim," she cried. "You are a\r
+dreadful old bear." And she ran across the room and hugged him.\r
+\r
+James Vane looked into his sister's face with tenderness. "I want you\r
+to come out with me for a walk, Sibyl. I don't suppose I shall ever\r
+see this horrid London again. I am sure I don't want to."\r
+\r
+"My son, don't say such dreadful things," murmured Mrs. Vane, taking up\r
+a tawdry theatrical dress, with a sigh, and beginning to patch it. She\r
+felt a little disappointed that he had not joined the group. It would\r
+have increased the theatrical picturesqueness of the situation.\r
+\r
+"Why not, Mother? I mean it."\r
+\r
+"You pain me, my son. I trust you will return from Australia in a\r
+position of affluence. I believe there is no society of any kind in\r
+the Colonies--nothing that I would call society--so when you have made\r
+your fortune, you must come back and assert yourself in London."\r
+\r
+"Society!" muttered the lad. "I don't want to know anything about\r
+that. I should like to make some money to take you and Sibyl off the\r
+stage. I hate it."\r
+\r
+"Oh, Jim!" said Sibyl, laughing, "how unkind of you! But are you\r
+really going for a walk with me? That will be nice! I was afraid you\r
+were going to say good-bye to some of your friends--to Tom Hardy, who\r
+gave you that hideous pipe, or Ned Langton, who makes fun of you for\r
+smoking it. It is very sweet of you to let me have your last\r
+afternoon. Where shall we go? Let us go to the park."\r
+\r
+"I am too shabby," he answered, frowning. "Only swell people go to the\r
+park."\r
+\r
+"Nonsense, Jim," she whispered, stroking the sleeve of his coat.\r
+\r
+He hesitated for a moment. "Very well," he said at last, "but don't be\r
+too long dressing." She danced out of the door. One could hear her\r
+singing as she ran upstairs. Her little feet pattered overhead.\r
+\r
+He walked up and down the room two or three times. Then he turned to\r
+the still figure in the chair. "Mother, are my things ready?" he asked.\r
+\r
+"Quite ready, James," she answered, keeping her eyes on her work. For\r
+some months past she had felt ill at ease when she was alone with this\r
+rough stern son of hers. Her shallow secret nature was troubled when\r
+their eyes met. She used to wonder if he suspected anything. The\r
+silence, for he made no other observation, became intolerable to her.\r
+She began to complain. Women defend themselves by attacking, just as\r
+they attack by sudden and strange surrenders. "I hope you will be\r
+contented, James, with your sea-faring life," she said. "You must\r
+remember that it is your own choice. You might have entered a\r
+solicitor's office. Solicitors are a very respectable class, and in\r
+the country often dine with the best families."\r
+\r
+"I hate offices, and I hate clerks," he replied. "But you are quite\r
+right. I have chosen my own life. All I say is, watch over Sibyl.\r
+Don't let her come to any harm. Mother, you must watch over her."\r
+\r
+"James, you really talk very strangely. Of course I watch over Sibyl."\r
+\r
+"I hear a gentleman comes every night to the theatre and goes behind to\r
+talk to her. Is that right? What about that?"\r
+\r
+"You are speaking about things you don't understand, James. In the\r
+profession we are accustomed to receive a great deal of most gratifying\r
+attention. I myself used to receive many bouquets at one time. That\r
+was when acting was really understood. As for Sibyl, I do not know at\r
+present whether her attachment is serious or not. But there is no\r
+doubt that the young man in question is a perfect gentleman. He is\r
+always most polite to me. Besides, he has the appearance of being\r
+rich, and the flowers he sends are lovely."\r
+\r
+"You don't know his name, though," said the lad harshly.\r
+\r
+"No," answered his mother with a placid expression in her face. "He\r
+has not yet revealed his real name. I think it is quite romantic of\r
+him. He is probably a member of the aristocracy."\r
+\r
+James Vane bit his lip. "Watch over Sibyl, Mother," he cried, "watch\r
+over her."\r
+\r
+"My son, you distress me very much. Sibyl is always under my special\r
+care. Of course, if this gentleman is wealthy, there is no reason why\r
+she should not contract an alliance with him. I trust he is one of the\r
+aristocracy. He has all the appearance of it, I must say. It might be\r
+a most brilliant marriage for Sibyl. They would make a charming\r
+couple. His good looks are really quite remarkable; everybody notices\r
+them."\r
+\r
+The lad muttered something to himself and drummed on the window-pane\r
+with his coarse fingers. He had just turned round to say something\r
+when the door opened and Sibyl ran in.\r
+\r
+"How serious you both are!" she cried. "What is the matter?"\r
+\r
+"Nothing," he answered. "I suppose one must be serious sometimes.\r
+Good-bye, Mother; I will have my dinner at five o'clock. Everything is\r
+packed, except my shirts, so you need not trouble."\r
+\r
+"Good-bye, my son," she answered with a bow of strained stateliness.\r
+\r
+She was extremely annoyed at the tone he had adopted with her, and\r
+there was something in his look that had made her feel afraid.\r
+\r
+"Kiss me, Mother," said the girl. Her flowerlike lips touched the\r
+withered cheek and warmed its frost.\r
+\r
+"My child! my child!" cried Mrs. Vane, looking up to the ceiling in\r
+search of an imaginary gallery.\r
+\r
+"Come, Sibyl," said her brother impatiently. He hated his mother's\r
+affectations.\r
+\r
+They went out into the flickering, wind-blown sunlight and strolled\r
+down the dreary Euston Road. The passersby glanced in wonder at the\r
+sullen heavy youth who, in coarse, ill-fitting clothes, was in the\r
+company of such a graceful, refined-looking girl. He was like a common\r
+gardener walking with a rose.\r
+\r
+Jim frowned from time to time when he caught the inquisitive glance of\r
+some stranger. He had that dislike of being stared at, which comes on\r
+geniuses late in life and never leaves the commonplace. Sibyl,\r
+however, was quite unconscious of the effect she was producing. Her\r
+love was trembling in laughter on her lips. She was thinking of Prince\r
+Charming, and, that she might think of him all the more, she did not\r
+talk of him, but prattled on about the ship in which Jim was going to\r
+sail, about the gold he was certain to find, about the wonderful\r
+heiress whose life he was to save from the wicked, red-shirted\r
+bushrangers. For he was not to remain a sailor, or a supercargo, or\r
+whatever he was going to be. Oh, no! A sailor's existence was\r
+dreadful. Fancy being cooped up in a horrid ship, with the hoarse,\r
+hump-backed waves trying to get in, and a black wind blowing the masts\r
+down and tearing the sails into long screaming ribands! He was to\r
+leave the vessel at Melbourne, bid a polite good-bye to the captain,\r
+and go off at once to the gold-fields. Before a week was over he was to\r
+come across a large nugget of pure gold, the largest nugget that had\r
+ever been discovered, and bring it down to the coast in a waggon\r
+guarded by six mounted policemen. The bushrangers were to attack them\r
+three times, and be defeated with immense slaughter. Or, no. He was\r
+not to go to the gold-fields at all. They were horrid places, where\r
+men got intoxicated, and shot each other in bar-rooms, and used bad\r
+language. He was to be a nice sheep-farmer, and one evening, as he was\r
+riding home, he was to see the beautiful heiress being carried off by a\r
+robber on a black horse, and give chase, and rescue her. Of course,\r
+she would fall in love with him, and he with her, and they would get\r
+married, and come home, and live in an immense house in London. Yes,\r
+there were delightful things in store for him. But he must be very\r
+good, and not lose his temper, or spend his money foolishly. She was\r
+only a year older than he was, but she knew so much more of life. He\r
+must be sure, also, to write to her by every mail, and to say his\r
+prayers each night before he went to sleep. God was very good, and\r
+would watch over him. She would pray for him, too, and in a few years\r
+he would come back quite rich and happy.\r
+\r
+The lad listened sulkily to her and made no answer. He was heart-sick\r
+at leaving home.\r
+\r
+Yet it was not this alone that made him gloomy and morose.\r
+Inexperienced though he was, he had still a strong sense of the danger\r
+of Sibyl's position. This young dandy who was making love to her could\r
+mean her no good. He was a gentleman, and he hated him for that, hated\r
+him through some curious race-instinct for which he could not account,\r
+and which for that reason was all the more dominant within him. He was\r
+conscious also of the shallowness and vanity of his mother's nature,\r
+and in that saw infinite peril for Sibyl and Sibyl's happiness.\r
+Children begin by loving their parents; as they grow older they judge\r
+them; sometimes they forgive them.\r
+\r
+His mother! He had something on his mind to ask of her, something that\r
+he had brooded on for many months of silence. A chance phrase that he\r
+had heard at the theatre, a whispered sneer that had reached his ears\r
+one night as he waited at the stage-door, had set loose a train of\r
+horrible thoughts. He remembered it as if it had been the lash of a\r
+hunting-crop across his face. His brows knit together into a wedge-like\r
+furrow, and with a twitch of pain he bit his underlip.\r
+\r
+"You are not listening to a word I am saying, Jim," cried Sibyl, "and I\r
+am making the most delightful plans for your future. Do say something."\r
+\r
+"What do you want me to say?"\r
+\r
+"Oh! that you will be a good boy and not forget us," she answered,\r
+smiling at him.\r
+\r
+He shrugged his shoulders. "You are more likely to forget me than I am\r
+to forget you, Sibyl."\r
+\r
+She flushed. "What do you mean, Jim?" she asked.\r
+\r
+"You have a new friend, I hear. Who is he? Why have you not told me\r
+about him? He means you no good."\r
+\r
+"Stop, Jim!" she exclaimed. "You must not say anything against him. I\r
+love him."\r
+\r
+"Why, you don't even know his name," answered the lad. "Who is he? I\r
+have a right to know."\r
+\r
+"He is called Prince Charming. Don't you like the name. Oh! you silly\r
+boy! you should never forget it. If you only saw him, you would think\r
+him the most wonderful person in the world. Some day you will meet\r
+him--when you come back from Australia. You will like him so much.\r
+Everybody likes him, and I ... love him. I wish you could come to the\r
+theatre to-night. He is going to be there, and I am to play Juliet.\r
+Oh! how I shall play it! Fancy, Jim, to be in love and play Juliet!\r
+To have him sitting there! To play for his delight! I am afraid I may\r
+frighten the company, frighten or enthrall them. To be in love is to\r
+surpass one's self. Poor dreadful Mr. Isaacs will be shouting 'genius'\r
+to his loafers at the bar. He has preached me as a dogma; to-night he\r
+will announce me as a revelation. I feel it. And it is all his, his\r
+only, Prince Charming, my wonderful lover, my god of graces. But I am\r
+poor beside him. Poor? What does that matter? When poverty creeps in\r
+at the door, love flies in through the window. Our proverbs want\r
+rewriting. They were made in winter, and it is summer now; spring-time\r
+for me, I think, a very dance of blossoms in blue skies."\r
+\r
+"He is a gentleman," said the lad sullenly.\r
+\r
+"A prince!" she cried musically. "What more do you want?"\r
+\r
+"He wants to enslave you."\r
+\r
+"I shudder at the thought of being free."\r
+\r
+"I want you to beware of him."\r
+\r
+"To see him is to worship him; to know him is to trust him."\r
+\r
+"Sibyl, you are mad about him."\r
+\r
+She laughed and took his arm. "You dear old Jim, you talk as if you\r
+were a hundred. Some day you will be in love yourself. Then you will\r
+know what it is. Don't look so sulky. Surely you should be glad to\r
+think that, though you are going away, you leave me happier than I have\r
+ever been before. Life has been hard for us both, terribly hard and\r
+difficult. But it will be different now. You are going to a new\r
+world, and I have found one. Here are two chairs; let us sit down and\r
+see the smart people go by."\r
+\r
+They took their seats amidst a crowd of watchers. The tulip-beds\r
+across the road flamed like throbbing rings of fire. A white\r
+dust--tremulous cloud of orris-root it seemed--hung in the panting air.\r
+The brightly coloured parasols danced and dipped like monstrous\r
+butterflies.\r
+\r
+She made her brother talk of himself, his hopes, his prospects. He\r
+spoke slowly and with effort. They passed words to each other as\r
+players at a game pass counters. Sibyl felt oppressed. She could not\r
+communicate her joy. A faint smile curving that sullen mouth was all\r
+the echo she could win. After some time she became silent. Suddenly\r
+she caught a glimpse of golden hair and laughing lips, and in an open\r
+carriage with two ladies Dorian Gray drove past.\r
+\r
+She started to her feet. "There he is!" she cried.\r
+\r
+"Who?" said Jim Vane.\r
+\r
+"Prince Charming," she answered, looking after the victoria.\r
+\r
+He jumped up and seized her roughly by the arm. "Show him to me.\r
+Which is he? Point him out. I must see him!" he exclaimed; but at\r
+that moment the Duke of Berwick's four-in-hand came between, and when\r
+it had left the space clear, the carriage had swept out of the park.\r
+\r
+"He is gone," murmured Sibyl sadly. "I wish you had seen him."\r
+\r
+"I wish I had, for as sure as there is a God in heaven, if he ever does\r
+you any wrong, I shall kill him."\r
+\r
+She looked at him in horror. He repeated his words. They cut the air\r
+like a dagger. The people round began to gape. A lady standing close\r
+to her tittered.\r
+\r
+"Come away, Jim; come away," she whispered. He followed her doggedly\r
+as she passed through the crowd. He felt glad at what he had said.\r
+\r
+When they reached the Achilles Statue, she turned round. There was\r
+pity in her eyes that became laughter on her lips. She shook her head\r
+at him. "You are foolish, Jim, utterly foolish; a bad-tempered boy,\r
+that is all. How can you say such horrible things? You don't know\r
+what you are talking about. You are simply jealous and unkind. Ah! I\r
+wish you would fall in love. Love makes people good, and what you said\r
+was wicked."\r
+\r
+"I am sixteen," he answered, "and I know what I am about. Mother is no\r
+help to you. She doesn't understand how to look after you. I wish now\r
+that I was not going to Australia at all. I have a great mind to chuck\r
+the whole thing up. I would, if my articles hadn't been signed."\r
+\r
+"Oh, don't be so serious, Jim. You are like one of the heroes of those\r
+silly melodramas Mother used to be so fond of acting in. I am not\r
+going to quarrel with you. I have seen him, and oh! to see him is\r
+perfect happiness. We won't quarrel. I know you would never harm any\r
+one I love, would you?"\r
+\r
+"Not as long as you love him, I suppose," was the sullen answer.\r
+\r
+"I shall love him for ever!" she cried.\r
+\r
+"And he?"\r
+\r
+"For ever, too!"\r
+\r
+"He had better."\r
+\r
+She shrank from him. Then she laughed and put her hand on his arm. He\r
+was merely a boy.\r
+\r
+At the Marble Arch they hailed an omnibus, which left them close to\r
+their shabby home in the Euston Road. It was after five o'clock, and\r
+Sibyl had to lie down for a couple of hours before acting. Jim\r
+insisted that she should do so. He said that he would sooner part with\r
+her when their mother was not present. She would be sure to make a\r
+scene, and he detested scenes of every kind.\r
+\r
+In Sybil's own room they parted. There was jealousy in the lad's\r
+heart, and a fierce murderous hatred of the stranger who, as it seemed\r
+to him, had come between them. Yet, when her arms were flung round his\r
+neck, and her fingers strayed through his hair, he softened and kissed\r
+her with real affection. There were tears in his eyes as he went\r
+downstairs.\r
+\r
+His mother was waiting for him below. She grumbled at his\r
+unpunctuality, as he entered. He made no answer, but sat down to his\r
+meagre meal. The flies buzzed round the table and crawled over the\r
+stained cloth. Through the rumble of omnibuses, and the clatter of\r
+street-cabs, he could hear the droning voice devouring each minute that\r
+was left to him.\r
+\r
+After some time, he thrust away his plate and put his head in his\r
+hands. He felt that he had a right to know. It should have been told\r
+to him before, if it was as he suspected. Leaden with fear, his mother\r
+watched him. Words dropped mechanically from her lips. A tattered\r
+lace handkerchief twitched in her fingers. When the clock struck six,\r
+he got up and went to the door. Then he turned back and looked at her.\r
+Their eyes met. In hers he saw a wild appeal for mercy. It enraged\r
+him.\r
+\r
+"Mother, I have something to ask you," he said. Her eyes wandered\r
+vaguely about the room. She made no answer. "Tell me the truth. I\r
+have a right to know. Were you married to my father?"\r
+\r
+She heaved a deep sigh. It was a sigh of relief. The terrible moment,\r
+the moment that night and day, for weeks and months, she had dreaded,\r
+had come at last, and yet she felt no terror. Indeed, in some measure\r
+it was a disappointment to her. The vulgar directness of the question\r
+called for a direct answer. The situation had not been gradually led\r
+up to. It was crude. It reminded her of a bad rehearsal.\r
+\r
+"No," she answered, wondering at the harsh simplicity of life.\r
+\r
+"My father was a scoundrel then!" cried the lad, clenching his fists.\r
+\r
+She shook her head. "I knew he was not free. We loved each other very\r
+much. If he had lived, he would have made provision for us. Don't\r
+speak against him, my son. He was your father, and a gentleman.\r
+Indeed, he was highly connected."\r
+\r
+An oath broke from his lips. "I don't care for myself," he exclaimed,\r
+"but don't let Sibyl.... It is a gentleman, isn't it, who is in love\r
+with her, or says he is? Highly connected, too, I suppose."\r
+\r
+For a moment a hideous sense of humiliation came over the woman. Her\r
+head drooped. She wiped her eyes with shaking hands. "Sibyl has a\r
+mother," she murmured; "I had none."\r
+\r
+The lad was touched. He went towards her, and stooping down, he kissed\r
+her. "I am sorry if I have pained you by asking about my father," he\r
+said, "but I could not help it. I must go now. Good-bye. Don't forget\r
+that you will have only one child now to look after, and believe me\r
+that if this man wrongs my sister, I will find out who he is, track him\r
+down, and kill him like a dog. I swear it."\r
+\r
+The exaggerated folly of the threat, the passionate gesture that\r
+accompanied it, the mad melodramatic words, made life seem more vivid\r
+to her. She was familiar with the atmosphere. She breathed more\r
+freely, and for the first time for many months she really admired her\r
+son. She would have liked to have continued the scene on the same\r
+emotional scale, but he cut her short. Trunks had to be carried down\r
+and mufflers looked for. The lodging-house drudge bustled in and out.\r
+There was the bargaining with the cabman. The moment was lost in\r
+vulgar details. It was with a renewed feeling of disappointment that\r
+she waved the tattered lace handkerchief from the window, as her son\r
+drove away. She was conscious that a great opportunity had been\r
+wasted. She consoled herself by telling Sibyl how desolate she felt\r
+her life would be, now that she had only one child to look after. She\r
+remembered the phrase. It had pleased her. Of the threat she said\r
+nothing. It was vividly and dramatically expressed. She felt that\r
+they would all laugh at it some day.\r

+\r
+CHAPTER 6\r
+\r
+"I suppose you have heard the news, Basil?" said Lord Henry that\r
+evening as Hallward was shown into a little private room at the Bristol\r
+where dinner had been laid for three.\r
+\r
+"No, Harry," answered the artist, giving his hat and coat to the bowing\r
+waiter. "What is it? Nothing about politics, I hope! They don't\r
+interest me. There is hardly a single person in the House of Commons\r
+worth painting, though many of them would be the better for a little\r
+whitewashing."\r
+\r
+"Dorian Gray is engaged to be married," said Lord Henry, watching him\r
+as he spoke.\r
+\r
+Hallward started and then frowned. "Dorian engaged to be married!" he\r
+cried. "Impossible!"\r
+\r
+"It is perfectly true."\r
+\r
+"To whom?"\r
+\r
+"To some little actress or other."\r
+\r
+"I can't believe it. Dorian is far too sensible."\r
+\r
+"Dorian is far too wise not to do foolish things now and then, my dear\r
+Basil."\r
+\r
+"Marriage is hardly a thing that one can do now and then, Harry."\r
+\r
+"Except in America," rejoined Lord Henry languidly. "But I didn't say\r
+he was married. I said he was engaged to be married. There is a great\r
+difference. I have a distinct remembrance of being married, but I have\r
+no recollection at all of being engaged. I am inclined to think that I\r
+never was engaged."\r
+\r
+"But think of Dorian's birth, and position, and wealth. It would be\r
+absurd for him to marry so much beneath him."\r
+\r
+"If you want to make him marry this girl, tell him that, Basil. He is\r
+sure to do it, then. Whenever a man does a thoroughly stupid thing, it\r
+is always from the noblest motives."\r
+\r
+"I hope the girl is good, Harry. I don't want to see Dorian tied to\r
+some vile creature, who might degrade his nature and ruin his\r
+intellect."\r
+\r
+"Oh, she is better than good--she is beautiful," murmured Lord Henry,\r
+sipping a glass of vermouth and orange-bitters. "Dorian says she is\r
+beautiful, and he is not often wrong about things of that kind. Your\r
+portrait of him has quickened his appreciation of the personal\r
+appearance of other people. It has had that excellent effect, amongst\r
+others. We are to see her to-night, if that boy doesn't forget his\r
+appointment."\r
+\r
+"Are you serious?"\r
+\r
+"Quite serious, Basil. I should be miserable if I thought I should\r
+ever be more serious than I am at the present moment."\r
+\r
+"But do you approve of it, Harry?" asked the painter, walking up and\r
+down the room and biting his lip. "You can't approve of it, possibly.\r
+It is some silly infatuation."\r
+\r
+"I never approve, or disapprove, of anything now. It is an absurd\r
+attitude to take towards life. We are not sent into the world to air\r
+our moral prejudices. I never take any notice of what common people\r
+say, and I never interfere with what charming people do. If a\r
+personality fascinates me, whatever mode of expression that personality\r
+selects is absolutely delightful to me. Dorian Gray falls in love with\r
+a beautiful girl who acts Juliet, and proposes to marry her. Why not?\r
+If he wedded Messalina, he would be none the less interesting. You\r
+know I am not a champion of marriage. The real drawback to marriage is\r
+that it makes one unselfish. And unselfish people are colourless.\r
+They lack individuality. Still, there are certain temperaments that\r
+marriage makes more complex. They retain their egotism, and add to it\r
+many other egos. They are forced to have more than one life. They\r
+become more highly organized, and to be highly organized is, I should\r
+fancy, the object of man's existence. Besides, every experience is of\r
+value, and whatever one may say against marriage, it is certainly an\r
+experience. I hope that Dorian Gray will make this girl his wife,\r
+passionately adore her for six months, and then suddenly become\r
+fascinated by some one else. He would be a wonderful study."\r
+\r
+"You don't mean a single word of all that, Harry; you know you don't.\r
+If Dorian Gray's life were spoiled, no one would be sorrier than\r
+yourself. You are much better than you pretend to be."\r
+\r
+Lord Henry laughed. "The reason we all like to think so well of others\r
+is that we are all afraid for ourselves. The basis of optimism is\r
+sheer terror. We think that we are generous because we credit our\r
+neighbour with the possession of those virtues that are likely to be a\r
+benefit to us. We praise the banker that we may overdraw our account,\r
+and find good qualities in the highwayman in the hope that he may spare\r
+our pockets. I mean everything that I have said. I have the greatest\r
+contempt for optimism. As for a spoiled life, no life is spoiled but\r
+one whose growth is arrested. If you want to mar a nature, you have\r
+merely to reform it. As for marriage, of course that would be silly,\r
+but there are other and more interesting bonds between men and women.\r
+I will certainly encourage them. They have the charm of being\r
+fashionable. But here is Dorian himself. He will tell you more than I\r
+can."\r
+\r
+"My dear Harry, my dear Basil, you must both congratulate me!" said the\r
+lad, throwing off his evening cape with its satin-lined wings and\r
+shaking each of his friends by the hand in turn. "I have never been so\r
+happy. Of course, it is sudden--all really delightful things are. And\r
+yet it seems to me to be the one thing I have been looking for all my\r
+life." He was flushed with excitement and pleasure, and looked\r
+extraordinarily handsome.\r
+\r
+"I hope you will always be very happy, Dorian," said Hallward, "but I\r
+don't quite forgive you for not having let me know of your engagement.\r
+You let Harry know."\r
+\r
+"And I don't forgive you for being late for dinner," broke in Lord\r
+Henry, putting his hand on the lad's shoulder and smiling as he spoke.\r
+"Come, let us sit down and try what the new _chef_ here is like, and then\r
+you will tell us how it all came about."\r
+\r
+"There is really not much to tell," cried Dorian as they took their\r
+seats at the small round table. "What happened was simply this. After\r
+I left you yesterday evening, Harry, I dressed, had some dinner at that\r
+little Italian restaurant in Rupert Street you introduced me to, and\r
+went down at eight o'clock to the theatre. Sibyl was playing Rosalind.\r
+Of course, the scenery was dreadful and the Orlando absurd. But Sibyl!\r
+You should have seen her! When she came on in her boy's clothes, she\r
+was perfectly wonderful. She wore a moss-coloured velvet jerkin with\r
+cinnamon sleeves, slim, brown, cross-gartered hose, a dainty little\r
+green cap with a hawk's feather caught in a jewel, and a hooded cloak\r
+lined with dull red. She had never seemed to me more exquisite. She\r
+had all the delicate grace of that Tanagra figurine that you have in\r
+your studio, Basil. Her hair clustered round her face like dark leaves\r
+round a pale rose. As for her acting--well, you shall see her\r
+to-night. She is simply a born artist. I sat in the dingy box\r
+absolutely enthralled. I forgot that I was in London and in the\r
+nineteenth century. I was away with my love in a forest that no man\r
+had ever seen. After the performance was over, I went behind and spoke\r
+to her. As we were sitting together, suddenly there came into her eyes\r
+a look that I had never seen there before. My lips moved towards hers.\r
+We kissed each other. I can't describe to you what I felt at that\r
+moment. It seemed to me that all my life had been narrowed to one\r
+perfect point of rose-coloured joy. She trembled all over and shook\r
+like a white narcissus. Then she flung herself on her knees and kissed\r
+my hands. I feel that I should not tell you all this, but I can't help\r
+it. Of course, our engagement is a dead secret. She has not even told\r
+her own mother. I don't know what my guardians will say. Lord Radley\r
+is sure to be furious. I don't care. I shall be of age in less than a\r
+year, and then I can do what I like. I have been right, Basil, haven't\r
+I, to take my love out of poetry and to find my wife in Shakespeare's\r
+plays? Lips that Shakespeare taught to speak have whispered their\r
+secret in my ear. I have had the arms of Rosalind around me, and\r
+kissed Juliet on the mouth."\r
+\r
+"Yes, Dorian, I suppose you were right," said Hallward slowly.\r
+\r
+"Have you seen her to-day?" asked Lord Henry.\r
+\r
+Dorian Gray shook his head. "I left her in the forest of Arden; I\r
+shall find her in an orchard in Verona."\r
+\r
+Lord Henry sipped his champagne in a meditative manner. "At what\r
+particular point did you mention the word marriage, Dorian? And what\r
+did she say in answer? Perhaps you forgot all about it."\r
+\r
+"My dear Harry, I did not treat it as a business transaction, and I did\r
+not make any formal proposal. I told her that I loved her, and she\r
+said she was not worthy to be my wife. Not worthy! Why, the whole\r
+world is nothing to me compared with her."\r
+\r
+"Women are wonderfully practical," murmured Lord Henry, "much more\r
+practical than we are. In situations of that kind we often forget to\r
+say anything about marriage, and they always remind us."\r
+\r
+Hallward laid his hand upon his arm. "Don't, Harry. You have annoyed\r
+Dorian. He is not like other men. He would never bring misery upon\r
+any one. His nature is too fine for that."\r
+\r
+Lord Henry looked across the table. "Dorian is never annoyed with me,"\r
+he answered. "I asked the question for the best reason possible, for\r
+the only reason, indeed, that excuses one for asking any\r
+question--simple curiosity. I have a theory that it is always the\r
+women who propose to us, and not we who propose to the women. Except,\r
+of course, in middle-class life. But then the middle classes are not\r
+modern."\r
+\r
+Dorian Gray laughed, and tossed his head. "You are quite incorrigible,\r
+Harry; but I don't mind. It is impossible to be angry with you. When\r
+you see Sibyl Vane, you will feel that the man who could wrong her\r
+would be a beast, a beast without a heart. I cannot understand how any\r
+one can wish to shame the thing he loves. I love Sibyl Vane. I want\r
+to place her on a pedestal of gold and to see the world worship the\r
+woman who is mine. What is marriage? An irrevocable vow. You mock at\r
+it for that. Ah! don't mock. It is an irrevocable vow that I want to\r
+take. Her trust makes me faithful, her belief makes me good. When I\r
+am with her, I regret all that you have taught me. I become different\r
+from what you have known me to be. I am changed, and the mere touch of\r
+Sibyl Vane's hand makes me forget you and all your wrong, fascinating,\r
+poisonous, delightful theories."\r
+\r
+"And those are ...?" asked Lord Henry, helping himself to some salad.\r
+\r
+"Oh, your theories about life, your theories about love, your theories\r
+about pleasure. All your theories, in fact, Harry."\r
+\r
+"Pleasure is the only thing worth having a theory about," he answered\r
+in his slow melodious voice. "But I am afraid I cannot claim my theory\r
+as my own. It belongs to Nature, not to me. Pleasure is Nature's\r
+test, her sign of approval. When we are happy, we are always good, but\r
+when we are good, we are not always happy."\r
+\r
+"Ah! but what do you mean by good?" cried Basil Hallward.\r
+\r
+"Yes," echoed Dorian, leaning back in his chair and looking at Lord\r
+Henry over the heavy clusters of purple-lipped irises that stood in the\r
+centre of the table, "what do you mean by good, Harry?"\r
+\r
+"To be good is to be in harmony with one's self," he replied, touching\r
+the thin stem of his glass with his pale, fine-pointed fingers.\r
+"Discord is to be forced to be in harmony with others. One's own\r
+life--that is the important thing. As for the lives of one's\r
+neighbours, if one wishes to be a prig or a Puritan, one can flaunt\r
+one's moral views about them, but they are not one's concern. Besides,\r
+individualism has really the higher aim. Modern morality consists in\r
+accepting the standard of one's age. I consider that for any man of\r
+culture to accept the standard of his age is a form of the grossest\r
+immorality."\r
+\r
+"But, surely, if one lives merely for one's self, Harry, one pays a\r
+terrible price for doing so?" suggested the painter.\r
+\r
+"Yes, we are overcharged for everything nowadays. I should fancy that\r
+the real tragedy of the poor is that they can afford nothing but\r
+self-denial. Beautiful sins, like beautiful things, are the privilege\r
+of the rich."\r
+\r
+"One has to pay in other ways but money."\r
+\r
+"What sort of ways, Basil?"\r
+\r
+"Oh! I should fancy in remorse, in suffering, in ... well, in the\r
+consciousness of degradation."\r
+\r
+Lord Henry shrugged his shoulders. "My dear fellow, mediaeval art is\r
+charming, but mediaeval emotions are out of date. One can use them in\r
+fiction, of course. But then the only things that one can use in\r
+fiction are the things that one has ceased to use in fact. Believe me,\r
+no civilized man ever regrets a pleasure, and no uncivilized man ever\r
+knows what a pleasure is."\r
+\r
+"I know what pleasure is," cried Dorian Gray. "It is to adore some\r
+one."\r
+\r
+"That is certainly better than being adored," he answered, toying with\r
+some fruits. "Being adored is a nuisance. Women treat us just as\r
+humanity treats its gods. They worship us, and are always bothering us\r
+to do something for them."\r
+\r
+"I should have said that whatever they ask for they had first given to\r
+us," murmured the lad gravely. "They create love in our natures. They\r
+have a right to demand it back."\r
+\r
+"That is quite true, Dorian," cried Hallward.\r
+\r
+"Nothing is ever quite true," said Lord Henry.\r
+\r
+"This is," interrupted Dorian. "You must admit, Harry, that women give\r
+to men the very gold of their lives."\r
+\r
+"Possibly," he sighed, "but they invariably want it back in such very\r
+small change. That is the worry. Women, as some witty Frenchman once\r
+put it, inspire us with the desire to do masterpieces and always\r
+prevent us from carrying them out."\r
+\r
+"Harry, you are dreadful! I don't know why I like you so much."\r
+\r
+"You will always like me, Dorian," he replied. "Will you have some\r
+coffee, you fellows? Waiter, bring coffee, and _fine-champagne_, and\r
+some cigarettes. No, don't mind the cigarettes--I have some. Basil, I\r
+can't allow you to smoke cigars. You must have a cigarette. A\r
+cigarette is the perfect type of a perfect pleasure. It is exquisite,\r
+and it leaves one unsatisfied. What more can one want? Yes, Dorian,\r
+you will always be fond of me. I represent to you all the sins you\r
+have never had the courage to commit."\r
+\r
+"What nonsense you talk, Harry!" cried the lad, taking a light from a\r
+fire-breathing silver dragon that the waiter had placed on the table.\r
+"Let us go down to the theatre. When Sibyl comes on the stage you will\r
+have a new ideal of life. She will represent something to you that you\r
+have never known."\r
+\r
+"I have known everything," said Lord Henry, with a tired look in his\r
+eyes, "but I am always ready for a new emotion. I am afraid, however,\r
+that, for me at any rate, there is no such thing. Still, your\r
+wonderful girl may thrill me. I love acting. It is so much more real\r
+than life. Let us go. Dorian, you will come with me. I am so sorry,\r
+Basil, but there is only room for two in the brougham. You must follow\r
+us in a hansom."\r
+\r
+They got up and put on their coats, sipping their coffee standing. The\r
+painter was silent and preoccupied. There was a gloom over him. He\r
+could not bear this marriage, and yet it seemed to him to be better\r
+than many other things that might have happened. After a few minutes,\r
+they all passed downstairs. He drove off by himself, as had been\r
+arranged, and watched the flashing lights of the little brougham in\r
+front of him. A strange sense of loss came over him. He felt that\r
+Dorian Gray would never again be to him all that he had been in the\r
+past. Life had come between them.... His eyes darkened, and the\r
+crowded flaring streets became blurred to his eyes. When the cab drew\r
+up at the theatre, it seemed to him that he had grown years older.\r
+\r
+\r
+\r
+CHAPTER 7\r
+\r
+For some reason or other, the house was crowded that night, and the fat\r
+Jew manager who met them at the door was beaming from ear to ear with\r
+an oily tremulous smile. He escorted them to their box with a sort of\r
+pompous humility, waving his fat jewelled hands and talking at the top\r
+of his voice. Dorian Gray loathed him more than ever. He felt as if\r
+he had come to look for Miranda and had been met by Caliban. Lord\r
+Henry, upon the other hand, rather liked him. At least he declared he\r
+did, and insisted on shaking him by the hand and assuring him that he\r
+was proud to meet a man who had discovered a real genius and gone\r
+bankrupt over a poet. Hallward amused himself with watching the faces\r
+in the pit. The heat was terribly oppressive, and the huge sunlight\r
+flamed like a monstrous dahlia with petals of yellow fire. The youths\r
+in the gallery had taken off their coats and waistcoats and hung them\r
+over the side. They talked to each other across the theatre and shared\r
+their oranges with the tawdry girls who sat beside them. Some women\r
+were laughing in the pit. Their voices were horribly shrill and\r
+discordant. The sound of the popping of corks came from the bar.\r
+\r
+"What a place to find one's divinity in!" said Lord Henry.\r
+\r
+"Yes!" answered Dorian Gray. "It was here I found her, and she is\r
+divine beyond all living things. When she acts, you will forget\r
+everything. These common rough people, with their coarse faces and\r
+brutal gestures, become quite different when she is on the stage. They\r
+sit silently and watch her. They weep and laugh as she wills them to\r
+do. She makes them as responsive as a violin. She spiritualizes them,\r
+and one feels that they are of the same flesh and blood as one's self."\r
+\r
+"The same flesh and blood as one's self! Oh, I hope not!" exclaimed\r
+Lord Henry, who was scanning the occupants of the gallery through his\r
+opera-glass.\r
+\r
+"Don't pay any attention to him, Dorian," said the painter. "I\r
+understand what you mean, and I believe in this girl. Any one you love\r
+must be marvellous, and any girl who has the effect you describe must\r
+be fine and noble. To spiritualize one's age--that is something worth\r
+doing. If this girl can give a soul to those who have lived without\r
+one, if she can create the sense of beauty in people whose lives have\r
+been sordid and ugly, if she can strip them of their selfishness and\r
+lend them tears for sorrows that are not their own, she is worthy of\r
+all your adoration, worthy of the adoration of the world. This\r
+marriage is quite right. I did not think so at first, but I admit it\r
+now. The gods made Sibyl Vane for you. Without her you would have\r
+been incomplete."\r
+\r
+"Thanks, Basil," answered Dorian Gray, pressing his hand. "I knew that\r
+you would understand me. Harry is so cynical, he terrifies me. But\r
+here is the orchestra. It is quite dreadful, but it only lasts for\r
+about five minutes. Then the curtain rises, and you will see the girl\r
+to whom I am going to give all my life, to whom I have given everything\r
+that is good in me."\r
+\r
+A quarter of an hour afterwards, amidst an extraordinary turmoil of\r
+applause, Sibyl Vane stepped on to the stage. Yes, she was certainly\r
+lovely to look at--one of the loveliest creatures, Lord Henry thought,\r
+that he had ever seen. There was something of the fawn in her shy\r
+grace and startled eyes. A faint blush, like the shadow of a rose in a\r
+mirror of silver, came to her cheeks as she glanced at the crowded\r
+enthusiastic house. She stepped back a few paces and her lips seemed\r
+to tremble. Basil Hallward leaped to his feet and began to applaud.\r
+Motionless, and as one in a dream, sat Dorian Gray, gazing at her.\r
+Lord Henry peered through his glasses, murmuring, "Charming! charming!"\r
+\r
+The scene was the hall of Capulet's house, and Romeo in his pilgrim's\r
+dress had entered with Mercutio and his other friends. The band, such\r
+as it was, struck up a few bars of music, and the dance began. Through\r
+the crowd of ungainly, shabbily dressed actors, Sibyl Vane moved like a\r
+creature from a finer world. Her body swayed, while she danced, as a\r
+plant sways in the water. The curves of her throat were the curves of\r
+a white lily. Her hands seemed to be made of cool ivory.\r
+\r
+Yet she was curiously listless. She showed no sign of joy when her\r
+eyes rested on Romeo. The few words she had to speak--\r
+\r
+ Good pilgrim, you do wrong your hand too much,\r
+ Which mannerly devotion shows in this;\r
+ For saints have hands that pilgrims' hands do touch,\r
+ And palm to palm is holy palmers' kiss--\r
+\r
+with the brief dialogue that follows, were spoken in a thoroughly\r
+artificial manner. The voice was exquisite, but from the point of view\r
+of tone it was absolutely false. It was wrong in colour. It took away\r
+all the life from the verse. It made the passion unreal.\r
+\r
+Dorian Gray grew pale as he watched her. He was puzzled and anxious.\r
+Neither of his friends dared to say anything to him. She seemed to\r
+them to be absolutely incompetent. They were horribly disappointed.\r
+\r
+Yet they felt that the true test of any Juliet is the balcony scene of\r
+the second act. They waited for that. If she failed there, there was\r
+nothing in her.\r
+\r
+She looked charming as she came out in the moonlight. That could not\r
+be denied. But the staginess of her acting was unbearable, and grew\r
+worse as she went on. Her gestures became absurdly artificial. She\r
+overemphasized everything that she had to say. The beautiful passage--\r
+\r
+ Thou knowest the mask of night is on my face,\r
+ Else would a maiden blush bepaint my cheek\r
+ For that which thou hast heard me speak to-night--\r
+\r
+was declaimed with the painful precision of a schoolgirl who has been\r
+taught to recite by some second-rate professor of elocution. When she\r
+leaned over the balcony and came to those wonderful lines--\r
+\r
+ Although I joy in thee,\r
+ I have no joy of this contract to-night:\r
+ It is too rash, too unadvised, too sudden;\r
+ Too like the lightning, which doth cease to be\r
+ Ere one can say, "It lightens." Sweet, good-night!\r
+ This bud of love by summer's ripening breath\r
+ May prove a beauteous flower when next we meet--\r
+\r
+she spoke the words as though they conveyed no meaning to her. It was\r
+not nervousness. Indeed, so far from being nervous, she was absolutely\r
+self-contained. It was simply bad art. She was a complete failure.\r
+\r
+Even the common uneducated audience of the pit and gallery lost their\r
+interest in the play. They got restless, and began to talk loudly and\r
+to whistle. The Jew manager, who was standing at the back of the\r
+dress-circle, stamped and swore with rage. The only person unmoved was\r
+the girl herself.\r
+\r
+When the second act was over, there came a storm of hisses, and Lord\r
+Henry got up from his chair and put on his coat. "She is quite\r
+beautiful, Dorian," he said, "but she can't act. Let us go."\r
+\r
+"I am going to see the play through," answered the lad, in a hard\r
+bitter voice. "I am awfully sorry that I have made you waste an\r
+evening, Harry. I apologize to you both."\r
+\r
+"My dear Dorian, I should think Miss Vane was ill," interrupted\r
+Hallward. "We will come some other night."\r
+\r
+"I wish she were ill," he rejoined. "But she seems to me to be simply\r
+callous and cold. She has entirely altered. Last night she was a\r
+great artist. This evening she is merely a commonplace mediocre\r
+actress."\r
+\r
+"Don't talk like that about any one you love, Dorian. Love is a more\r
+wonderful thing than art."\r
+\r
+"They are both simply forms of imitation," remarked Lord Henry. "But\r
+do let us go. Dorian, you must not stay here any longer. It is not\r
+good for one's morals to see bad acting. Besides, I don't suppose you\r
+will want your wife to act, so what does it matter if she plays Juliet\r
+like a wooden doll? She is very lovely, and if she knows as little\r
+about life as she does about acting, she will be a delightful\r
+experience. There are only two kinds of people who are really\r
+fascinating--people who know absolutely everything, and people who know\r
+absolutely nothing. Good heavens, my dear boy, don't look so tragic!\r
+The secret of remaining young is never to have an emotion that is\r
+unbecoming. Come to the club with Basil and myself. We will smoke\r
+cigarettes and drink to the beauty of Sibyl Vane. She is beautiful.\r
+What more can you want?"\r
+\r
+"Go away, Harry," cried the lad. "I want to be alone. Basil, you must\r
+go. Ah! can't you see that my heart is breaking?" The hot tears came\r
+to his eyes. His lips trembled, and rushing to the back of the box, he\r
+leaned up against the wall, hiding his face in his hands.\r
+\r
+"Let us go, Basil," said Lord Henry with a strange tenderness in his\r
+voice, and the two young men passed out together.\r
+\r
+A few moments afterwards the footlights flared up and the curtain rose\r
+on the third act. Dorian Gray went back to his seat. He looked pale,\r
+and proud, and indifferent. The play dragged on, and seemed\r
+interminable. Half of the audience went out, tramping in heavy boots\r
+and laughing. The whole thing was a _fiasco_. The last act was played\r
+to almost empty benches. The curtain went down on a titter and some\r
+groans.\r
+\r
+As soon as it was over, Dorian Gray rushed behind the scenes into the\r
+greenroom. The girl was standing there alone, with a look of triumph\r
+on her face. Her eyes were lit with an exquisite fire. There was a\r
+radiance about her. Her parted lips were smiling over some secret of\r
+their own.\r
+\r
+When he entered, she looked at him, and an expression of infinite joy\r
+came over her. "How badly I acted to-night, Dorian!" she cried.\r
+\r
+"Horribly!" he answered, gazing at her in amazement. "Horribly! It\r
+was dreadful. Are you ill? You have no idea what it was. You have no\r
+idea what I suffered."\r
+\r
+The girl smiled. "Dorian," she answered, lingering over his name with\r
+long-drawn music in her voice, as though it were sweeter than honey to\r
+the red petals of her mouth. "Dorian, you should have understood. But\r
+you understand now, don't you?"\r
+\r
+"Understand what?" he asked, angrily.\r
+\r
+"Why I was so bad to-night. Why I shall always be bad. Why I shall\r
+never act well again."\r
+\r
+He shrugged his shoulders. "You are ill, I suppose. When you are ill\r
+you shouldn't act. You make yourself ridiculous. My friends were\r
+bored. I was bored."\r
+\r
+She seemed not to listen to him. She was transfigured with joy. An\r
+ecstasy of happiness dominated her.\r
+\r
+"Dorian, Dorian," she cried, "before I knew you, acting was the one\r
+reality of my life. It was only in the theatre that I lived. I\r
+thought that it was all true. I was Rosalind one night and Portia the\r
+other. The joy of Beatrice was my joy, and the sorrows of Cordelia\r
+were mine also. I believed in everything. The common people who acted\r
+with me seemed to me to be godlike. The painted scenes were my world.\r
+I knew nothing but shadows, and I thought them real. You came--oh, my\r
+beautiful love!--and you freed my soul from prison. You taught me what\r
+reality really is. To-night, for the first time in my life, I saw\r
+through the hollowness, the sham, the silliness of the empty pageant in\r
+which I had always played. To-night, for the first time, I became\r
+conscious that the Romeo was hideous, and old, and painted, that the\r
+moonlight in the orchard was false, that the scenery was vulgar, and\r
+that the words I had to speak were unreal, were not my words, were not\r
+what I wanted to say. You had brought me something higher, something\r
+of which all art is but a reflection. You had made me understand what\r
+love really is. My love! My love! Prince Charming! Prince of life!\r
+I have grown sick of shadows. You are more to me than all art can ever\r
+be. What have I to do with the puppets of a play? When I came on\r
+to-night, I could not understand how it was that everything had gone\r
+from me. I thought that I was going to be wonderful. I found that I\r
+could do nothing. Suddenly it dawned on my soul what it all meant.\r
+The knowledge was exquisite to me. I heard them hissing, and I smiled.\r
+What could they know of love such as ours? Take me away, Dorian--take\r
+me away with you, where we can be quite alone. I hate the stage. I\r
+might mimic a passion that I do not feel, but I cannot mimic one that\r
+burns me like fire. Oh, Dorian, Dorian, you understand now what it\r
+signifies? Even if I could do it, it would be profanation for me to\r
+play at being in love. You have made me see that."\r
+\r
+He flung himself down on the sofa and turned away his face. "You have\r
+killed my love," he muttered.\r
+\r
+She looked at him in wonder and laughed. He made no answer. She came\r
+across to him, and with her little fingers stroked his hair. She knelt\r
+down and pressed his hands to her lips. He drew them away, and a\r
+shudder ran through him.\r
+\r
+Then he leaped up and went to the door. "Yes," he cried, "you have\r
+killed my love. You used to stir my imagination. Now you don't even\r
+stir my curiosity. You simply produce no effect. I loved you because\r
+you were marvellous, because you had genius and intellect, because you\r
+realized the dreams of great poets and gave shape and substance to the\r
+shadows of art. You have thrown it all away. You are shallow and\r
+stupid. My God! how mad I was to love you! What a fool I have been!\r
+You are nothing to me now. I will never see you again. I will never\r
+think of you. I will never mention your name. You don't know what you\r
+were to me, once. Why, once ... Oh, I can't bear to think of it! I\r
+wish I had never laid eyes upon you! You have spoiled the romance of\r
+my life. How little you can know of love, if you say it mars your art!\r
+Without your art, you are nothing. I would have made you famous,\r
+splendid, magnificent. The world would have worshipped you, and you\r
+would have borne my name. What are you now? A third-rate actress with\r
+a pretty face."\r
+\r
+The girl grew white, and trembled. She clenched her hands together,\r
+and her voice seemed to catch in her throat. "You are not serious,\r
+Dorian?" she murmured. "You are acting."\r
+\r
+"Acting! I leave that to you. You do it so well," he answered\r
+bitterly.\r
+\r
+She rose from her knees and, with a piteous expression of pain in her\r
+face, came across the room to him. She put her hand upon his arm and\r
+looked into his eyes. He thrust her back. "Don't touch me!" he cried.\r
+\r
+A low moan broke from her, and she flung herself at his feet and lay\r
+there like a trampled flower. "Dorian, Dorian, don't leave me!" she\r
+whispered. "I am so sorry I didn't act well. I was thinking of you\r
+all the time. But I will try--indeed, I will try. It came so suddenly\r
+across me, my love for you. I think I should never have known it if\r
+you had not kissed me--if we had not kissed each other. Kiss me again,\r
+my love. Don't go away from me. I couldn't bear it. Oh! don't go\r
+away from me. My brother ... No; never mind. He didn't mean it. He\r
+was in jest.... But you, oh! can't you forgive me for to-night? I will\r
+work so hard and try to improve. Don't be cruel to me, because I love\r
+you better than anything in the world. After all, it is only once that\r
+I have not pleased you. But you are quite right, Dorian. I should\r
+have shown myself more of an artist. It was foolish of me, and yet I\r
+couldn't help it. Oh, don't leave me, don't leave me." A fit of\r
+passionate sobbing choked her. She crouched on the floor like a\r
+wounded thing, and Dorian Gray, with his beautiful eyes, looked down at\r
+her, and his chiselled lips curled in exquisite disdain. There is\r
+always something ridiculous about the emotions of people whom one has\r
+ceased to love. Sibyl Vane seemed to him to be absurdly melodramatic.\r
+Her tears and sobs annoyed him.\r
+\r
+"I am going," he said at last in his calm clear voice. "I don't wish\r
+to be unkind, but I can't see you again. You have disappointed me."\r
+\r
+She wept silently, and made no answer, but crept nearer. Her little\r
+hands stretched blindly out, and appeared to be seeking for him. He\r
+turned on his heel and left the room. In a few moments he was out of\r
+the theatre.\r
+\r
+Where he went to he hardly knew. He remembered wandering through dimly\r
+lit streets, past gaunt, black-shadowed archways and evil-looking\r
+houses. Women with hoarse voices and harsh laughter had called after\r
+him. Drunkards had reeled by, cursing and chattering to themselves\r
+like monstrous apes. He had seen grotesque children huddled upon\r
+door-steps, and heard shrieks and oaths from gloomy courts.\r
+\r
+As the dawn was just breaking, he found himself close to Covent Garden.\r
+The darkness lifted, and, flushed with faint fires, the sky hollowed\r
+itself into a perfect pearl. Huge carts filled with nodding lilies\r
+rumbled slowly down the polished empty street. The air was heavy with\r
+the perfume of the flowers, and their beauty seemed to bring him an\r
+anodyne for his pain. He followed into the market and watched the men\r
+unloading their waggons. A white-smocked carter offered him some\r
+cherries. He thanked him, wondered why he refused to accept any money\r
+for them, and began to eat them listlessly. They had been plucked at\r
+midnight, and the coldness of the moon had entered into them. A long\r
+line of boys carrying crates of striped tulips, and of yellow and red\r
+roses, defiled in front of him, threading their way through the huge,\r
+jade-green piles of vegetables. Under the portico, with its grey,\r
+sun-bleached pillars, loitered a troop of draggled bareheaded girls,\r
+waiting for the auction to be over. Others crowded round the swinging\r
+doors of the coffee-house in the piazza. The heavy cart-horses slipped\r
+and stamped upon the rough stones, shaking their bells and trappings.\r
+Some of the drivers were lying asleep on a pile of sacks. Iris-necked\r
+and pink-footed, the pigeons ran about picking up seeds.\r
+\r
+After a little while, he hailed a hansom and drove home. For a few\r
+moments he loitered upon the doorstep, looking round at the silent\r
+square, with its blank, close-shuttered windows and its staring blinds.\r
+The sky was pure opal now, and the roofs of the houses glistened like\r
+silver against it. From some chimney opposite a thin wreath of smoke\r
+was rising. It curled, a violet riband, through the nacre-coloured air.\r
+\r
+In the huge gilt Venetian lantern, spoil of some Doge's barge, that\r
+hung from the ceiling of the great, oak-panelled hall of entrance,\r
+lights were still burning from three flickering jets: thin blue petals\r
+of flame they seemed, rimmed with white fire. He turned them out and,\r
+having thrown his hat and cape on the table, passed through the library\r
+towards the door of his bedroom, a large octagonal chamber on the\r
+ground floor that, in his new-born feeling for luxury, he had just had\r
+decorated for himself and hung with some curious Renaissance tapestries\r
+that had been discovered stored in a disused attic at Selby Royal. As\r
+he was turning the handle of the door, his eye fell upon the portrait\r
+Basil Hallward had painted of him. He started back as if in surprise.\r
+Then he went on into his own room, looking somewhat puzzled. After he\r
+had taken the button-hole out of his coat, he seemed to hesitate.\r
+Finally, he came back, went over to the picture, and examined it. In\r
+the dim arrested light that struggled through the cream-coloured silk\r
+blinds, the face appeared to him to be a little changed. The\r
+expression looked different. One would have said that there was a\r
+touch of cruelty in the mouth. It was certainly strange.\r
+\r
+He turned round and, walking to the window, drew up the blind. The\r
+bright dawn flooded the room and swept the fantastic shadows into dusky\r
+corners, where they lay shuddering. But the strange expression that he\r
+had noticed in the face of the portrait seemed to linger there, to be\r
+more intensified even. The quivering ardent sunlight showed him the\r
+lines of cruelty round the mouth as clearly as if he had been looking\r
+into a mirror after he had done some dreadful thing.\r
+\r
+He winced and, taking up from the table an oval glass framed in ivory\r
+Cupids, one of Lord Henry's many presents to him, glanced hurriedly\r
+into its polished depths. No line like that warped his red lips. What\r
+did it mean?\r
+\r
+He rubbed his eyes, and came close to the picture, and examined it\r
+again. There were no signs of any change when he looked into the\r
+actual painting, and yet there was no doubt that the whole expression\r
+had altered. It was not a mere fancy of his own. The thing was\r
+horribly apparent.\r
+\r
+He threw himself into a chair and began to think. Suddenly there\r
+flashed across his mind what he had said in Basil Hallward's studio the\r
+day the picture had been finished. Yes, he remembered it perfectly.\r
+He had uttered a mad wish that he himself might remain young, and the\r
+portrait grow old; that his own beauty might be untarnished, and the\r
+face on the canvas bear the burden of his passions and his sins; that\r
+the painted image might be seared with the lines of suffering and\r
+thought, and that he might keep all the delicate bloom and loveliness\r
+of his then just conscious boyhood. Surely his wish had not been\r
+fulfilled? Such things were impossible. It seemed monstrous even to\r
+think of them. And, yet, there was the picture before him, with the\r
+touch of cruelty in the mouth.\r
+\r
+Cruelty! Had he been cruel? It was the girl's fault, not his. He had\r
+dreamed of her as a great artist, had given his love to her because he\r
+had thought her great. Then she had disappointed him. She had been\r
+shallow and unworthy. And, yet, a feeling of infinite regret came over\r
+him, as he thought of her lying at his feet sobbing like a little\r
+child. He remembered with what callousness he had watched her. Why\r
+had he been made like that? Why had such a soul been given to him?\r
+But he had suffered also. During the three terrible hours that the\r
+play had lasted, he had lived centuries of pain, aeon upon aeon of\r
+torture. His life was well worth hers. She had marred him for a\r
+moment, if he had wounded her for an age. Besides, women were better\r
+suited to bear sorrow than men. They lived on their emotions. They\r
+only thought of their emotions. When they took lovers, it was merely\r
+to have some one with whom they could have scenes. Lord Henry had told\r
+him that, and Lord Henry knew what women were. Why should he trouble\r
+about Sibyl Vane? She was nothing to him now.\r
+\r
+But the picture? What was he to say of that? It held the secret of\r
+his life, and told his story. It had taught him to love his own\r
+beauty. Would it teach him to loathe his own soul? Would he ever look\r
+at it again?\r
+\r
+No; it was merely an illusion wrought on the troubled senses. The\r
+horrible night that he had passed had left phantoms behind it.\r
+Suddenly there had fallen upon his brain that tiny scarlet speck that\r
+makes men mad. The picture had not changed. It was folly to think so.\r
+\r
+Yet it was watching him, with its beautiful marred face and its cruel\r
+smile. Its bright hair gleamed in the early sunlight. Its blue eyes\r
+met his own. A sense of infinite pity, not for himself, but for the\r
+painted image of himself, came over him. It had altered already, and\r
+would alter more. Its gold would wither into grey. Its red and white\r
+roses would die. For every sin that he committed, a stain would fleck\r
+and wreck its fairness. But he would not sin. The picture, changed or\r
+unchanged, would be to him the visible emblem of conscience. He would\r
+resist temptation. He would not see Lord Henry any more--would not, at\r
+any rate, listen to those subtle poisonous theories that in Basil\r
+Hallward's garden had first stirred within him the passion for\r
+impossible things. He would go back to Sibyl Vane, make her amends,\r
+marry her, try to love her again. Yes, it was his duty to do so. She\r
+must have suffered more than he had. Poor child! He had been selfish\r
+and cruel to her. The fascination that she had exercised over him\r
+would return. They would be happy together. His life with her would\r
+be beautiful and pure.\r
+\r
+He got up from his chair and drew a large screen right in front of the\r
+portrait, shuddering as he glanced at it. "How horrible!" he murmured\r
+to himself, and he walked across to the window and opened it. When he\r
+stepped out on to the grass, he drew a deep breath. The fresh morning\r
+air seemed to drive away all his sombre passions. He thought only of\r
+Sibyl. A faint echo of his love came back to him. He repeated her\r
+name over and over again. The birds that were singing in the\r
+dew-drenched garden seemed to be telling the flowers about her.\r
+\r
+\r
+\r
+CHAPTER 8\r
+\r
+It was long past noon when he awoke. His valet had crept several times\r
+on tiptoe into the room to see if he was stirring, and had wondered\r
+what made his young master sleep so late. Finally his bell sounded,\r
+and Victor came in softly with a cup of tea, and a pile of letters, on\r
+a small tray of old Sevres china, and drew back the olive-satin\r
+curtains, with their shimmering blue lining, that hung in front of the\r
+three tall windows.\r
+\r
+"Monsieur has well slept this morning," he said, smiling.\r
+\r
+"What o'clock is it, Victor?" asked Dorian Gray drowsily.\r
+\r
+"One hour and a quarter, Monsieur."\r
+\r
+How late it was! He sat up, and having sipped some tea, turned over\r
+his letters. One of them was from Lord Henry, and had been brought by\r
+hand that morning. He hesitated for a moment, and then put it aside.\r
+The others he opened listlessly. They contained the usual collection\r
+of cards, invitations to dinner, tickets for private views, programmes\r
+of charity concerts, and the like that are showered on fashionable\r
+young men every morning during the season. There was a rather heavy\r
+bill for a chased silver Louis-Quinze toilet-set that he had not yet\r
+had the courage to send on to his guardians, who were extremely\r
+old-fashioned people and did not realize that we live in an age when\r
+unnecessary things are our only necessities; and there were several\r
+very courteously worded communications from Jermyn Street money-lenders\r
+offering to advance any sum of money at a moment's notice and at the\r
+most reasonable rates of interest.\r
+\r
+After about ten minutes he got up, and throwing on an elaborate\r
+dressing-gown of silk-embroidered cashmere wool, passed into the\r
+onyx-paved bathroom. The cool water refreshed him after his long\r
+sleep. He seemed to have forgotten all that he had gone through. A\r
+dim sense of having taken part in some strange tragedy came to him once\r
+or twice, but there was the unreality of a dream about it.\r
+\r
+As soon as he was dressed, he went into the library and sat down to a\r
+light French breakfast that had been laid out for him on a small round\r
+table close to the open window. It was an exquisite day. The warm air\r
+seemed laden with spices. A bee flew in and buzzed round the\r
+blue-dragon bowl that, filled with sulphur-yellow roses, stood before\r
+him. He felt perfectly happy.\r
+\r
+Suddenly his eye fell on the screen that he had placed in front of the\r
+portrait, and he started.\r
+\r
+"Too cold for Monsieur?" asked his valet, putting an omelette on the\r
+table. "I shut the window?"\r
+\r
+Dorian shook his head. "I am not cold," he murmured.\r
+\r
+Was it all true? Had the portrait really changed? Or had it been\r
+simply his own imagination that had made him see a look of evil where\r
+there had been a look of joy? Surely a painted canvas could not alter?\r
+The thing was absurd. It would serve as a tale to tell Basil some day.\r
+It would make him smile.\r
+\r
+And, yet, how vivid was his recollection of the whole thing! First in\r
+the dim twilight, and then in the bright dawn, he had seen the touch of\r
+cruelty round the warped lips. He almost dreaded his valet leaving the\r
+room. He knew that when he was alone he would have to examine the\r
+portrait. He was afraid of certainty. When the coffee and cigarettes\r
+had been brought and the man turned to go, he felt a wild desire to\r
+tell him to remain. As the door was closing behind him, he called him\r
+back. The man stood waiting for his orders. Dorian looked at him for\r
+a moment. "I am not at home to any one, Victor," he said with a sigh.\r
+The man bowed and retired.\r
+\r
+Then he rose from the table, lit a cigarette, and flung himself down on\r
+a luxuriously cushioned couch that stood facing the screen. The screen\r
+was an old one, of gilt Spanish leather, stamped and wrought with a\r
+rather florid Louis-Quatorze pattern. He scanned it curiously,\r
+wondering if ever before it had concealed the secret of a man's life.\r
+\r
+Should he move it aside, after all? Why not let it stay there? What\r
+was the use of knowing? If the thing was true, it was terrible. If it\r
+was not true, why trouble about it? But what if, by some fate or\r
+deadlier chance, eyes other than his spied behind and saw the horrible\r
+change? What should he do if Basil Hallward came and asked to look at\r
+his own picture? Basil would be sure to do that. No; the thing had to\r
+be examined, and at once. Anything would be better than this dreadful\r
+state of doubt.\r
+\r
+He got up and locked both doors. At least he would be alone when he\r
+looked upon the mask of his shame. Then he drew the screen aside and\r
+saw himself face to face. It was perfectly true. The portrait had\r
+altered.\r
+\r
+As he often remembered afterwards, and always with no small wonder, he\r
+found himself at first gazing at the portrait with a feeling of almost\r
+scientific interest. That such a change should have taken place was\r
+incredible to him. And yet it was a fact. Was there some subtle\r
+affinity between the chemical atoms that shaped themselves into form\r
+and colour on the canvas and the soul that was within him? Could it be\r
+that what that soul thought, they realized?--that what it dreamed, they\r
+made true? Or was there some other, more terrible reason? He\r
+shuddered, and felt afraid, and, going back to the couch, lay there,\r
+gazing at the picture in sickened horror.\r
+\r
+One thing, however, he felt that it had done for him. It had made him\r
+conscious how unjust, how cruel, he had been to Sibyl Vane. It was not\r
+too late to make reparation for that. She could still be his wife.\r
+His unreal and selfish love would yield to some higher influence, would\r
+be transformed into some nobler passion, and the portrait that Basil\r
+Hallward had painted of him would be a guide to him through life, would\r
+be to him what holiness is to some, and conscience to others, and the\r
+fear of God to us all. There were opiates for remorse, drugs that\r
+could lull the moral sense to sleep. But here was a visible symbol of\r
+the degradation of sin. Here was an ever-present sign of the ruin men\r
+brought upon their souls.\r
+\r
+Three o'clock struck, and four, and the half-hour rang its double\r
+chime, but Dorian Gray did not stir. He was trying to gather up the\r
+scarlet threads of life and to weave them into a pattern; to find his\r
+way through the sanguine labyrinth of passion through which he was\r
+wandering. He did not know what to do, or what to think. Finally, he\r
+went over to the table and wrote a passionate letter to the girl he had\r
+loved, imploring her forgiveness and accusing himself of madness. He\r
+covered page after page with wild words of sorrow and wilder words of\r
+pain. There is a luxury in self-reproach. When we blame ourselves, we\r
+feel that no one else has a right to blame us. It is the confession,\r
+not the priest, that gives us absolution. When Dorian had finished the\r
+letter, he felt that he had been forgiven.\r
+\r
+Suddenly there came a knock to the door, and he heard Lord Henry's\r
+voice outside. "My dear boy, I must see you. Let me in at once. I\r
+can't bear your shutting yourself up like this."\r
+\r
+He made no answer at first, but remained quite still. The knocking\r
+still continued and grew louder. Yes, it was better to let Lord Henry\r
+in, and to explain to him the new life he was going to lead, to quarrel\r
+with him if it became necessary to quarrel, to part if parting was\r
+inevitable. He jumped up, drew the screen hastily across the picture,\r
+and unlocked the door.\r
+\r
+"I am so sorry for it all, Dorian," said Lord Henry as he entered.\r
+"But you must not think too much about it."\r
+\r
+"Do you mean about Sibyl Vane?" asked the lad.\r
+\r
+"Yes, of course," answered Lord Henry, sinking into a chair and slowly\r
+pulling off his yellow gloves. "It is dreadful, from one point of\r
+view, but it was not your fault. Tell me, did you go behind and see\r
+her, after the play was over?"\r
+\r
+"Yes."\r
+\r
+"I felt sure you had. Did you make a scene with her?"\r
+\r
+"I was brutal, Harry--perfectly brutal. But it is all right now. I am\r
+not sorry for anything that has happened. It has taught me to know\r
+myself better."\r
+\r
+"Ah, Dorian, I am so glad you take it in that way! I was afraid I\r
+would find you plunged in remorse and tearing that nice curly hair of\r
+yours."\r
+\r
+"I have got through all that," said Dorian, shaking his head and\r
+smiling. "I am perfectly happy now. I know what conscience is, to\r
+begin with. It is not what you told me it was. It is the divinest\r
+thing in us. Don't sneer at it, Harry, any more--at least not before\r
+me. I want to be good. I can't bear the idea of my soul being\r
+hideous."\r
+\r
+"A very charming artistic basis for ethics, Dorian! I congratulate you\r
+on it. But how are you going to begin?"\r
+\r
+"By marrying Sibyl Vane."\r
+\r
+"Marrying Sibyl Vane!" cried Lord Henry, standing up and looking at him\r
+in perplexed amazement. "But, my dear Dorian--"\r
+\r
+"Yes, Harry, I know what you are going to say. Something dreadful\r
+about marriage. Don't say it. Don't ever say things of that kind to\r
+me again. Two days ago I asked Sibyl to marry me. I am not going to\r
+break my word to her. She is to be my wife."\r
+\r
+"Your wife! Dorian! ... Didn't you get my letter? I wrote to you this\r
+morning, and sent the note down by my own man."\r
+\r
+"Your letter? Oh, yes, I remember. I have not read it yet, Harry. I\r
+was afraid there might be something in it that I wouldn't like. You\r
+cut life to pieces with your epigrams."\r
+\r
+"You know nothing then?"\r
+\r
+"What do you mean?"\r
+\r
+Lord Henry walked across the room, and sitting down by Dorian Gray,\r
+took both his hands in his own and held them tightly. "Dorian," he\r
+said, "my letter--don't be frightened--was to tell you that Sibyl Vane\r
+is dead."\r
+\r
+A cry of pain broke from the lad's lips, and he leaped to his feet,\r
+tearing his hands away from Lord Henry's grasp. "Dead! Sibyl dead!\r
+It is not true! It is a horrible lie! How dare you say it?"\r
+\r
+"It is quite true, Dorian," said Lord Henry, gravely. "It is in all\r
+the morning papers. I wrote down to you to ask you not to see any one\r
+till I came. There will have to be an inquest, of course, and you must\r
+not be mixed up in it. Things like that make a man fashionable in\r
+Paris. But in London people are so prejudiced. Here, one should never\r
+make one's _debut_ with a scandal. One should reserve that to give an\r
+interest to one's old age. I suppose they don't know your name at the\r
+theatre? If they don't, it is all right. Did any one see you going\r
+round to her room? That is an important point."\r
+\r
+Dorian did not answer for a few moments. He was dazed with horror.\r
+Finally he stammered, in a stifled voice, "Harry, did you say an\r
+inquest? What did you mean by that? Did Sibyl--? Oh, Harry, I can't\r
+bear it! But be quick. Tell me everything at once."\r
+\r
+"I have no doubt it was not an accident, Dorian, though it must be put\r
+in that way to the public. It seems that as she was leaving the\r
+theatre with her mother, about half-past twelve or so, she said she had\r
+forgotten something upstairs. They waited some time for her, but she\r
+did not come down again. They ultimately found her lying dead on the\r
+floor of her dressing-room. She had swallowed something by mistake,\r
+some dreadful thing they use at theatres. I don't know what it was,\r
+but it had either prussic acid or white lead in it. I should fancy it\r
+was prussic acid, as she seems to have died instantaneously."\r
+\r
+"Harry, Harry, it is terrible!" cried the lad.\r
+\r
+"Yes; it is very tragic, of course, but you must not get yourself mixed\r
+up in it. I see by _The Standard_ that she was seventeen. I should have\r
+thought she was almost younger than that. She looked such a child, and\r
+seemed to know so little about acting. Dorian, you mustn't let this\r
+thing get on your nerves. You must come and dine with me, and\r
+afterwards we will look in at the opera. It is a Patti night, and\r
+everybody will be there. You can come to my sister's box. She has got\r
+some smart women with her."\r
+\r
+"So I have murdered Sibyl Vane," said Dorian Gray, half to himself,\r
+"murdered her as surely as if I had cut her little throat with a knife.\r
+Yet the roses are not less lovely for all that. The birds sing just as\r
+happily in my garden. And to-night I am to dine with you, and then go\r
+on to the opera, and sup somewhere, I suppose, afterwards. How\r
+extraordinarily dramatic life is! If I had read all this in a book,\r
+Harry, I think I would have wept over it. Somehow, now that it has\r
+happened actually, and to me, it seems far too wonderful for tears.\r
+Here is the first passionate love-letter I have ever written in my\r
+life. Strange, that my first passionate love-letter should have been\r
+addressed to a dead girl. Can they feel, I wonder, those white silent\r
+people we call the dead? Sibyl! Can she feel, or know, or listen?\r
+Oh, Harry, how I loved her once! It seems years ago to me now. She\r
+was everything to me. Then came that dreadful night--was it really\r
+only last night?--when she played so badly, and my heart almost broke.\r
+She explained it all to me. It was terribly pathetic. But I was not\r
+moved a bit. I thought her shallow. Suddenly something happened that\r
+made me afraid. I can't tell you what it was, but it was terrible. I\r
+said I would go back to her. I felt I had done wrong. And now she is\r
+dead. My God! My God! Harry, what shall I do? You don't know the\r
+danger I am in, and there is nothing to keep me straight. She would\r
+have done that for me. She had no right to kill herself. It was\r
+selfish of her."\r
+\r
+"My dear Dorian," answered Lord Henry, taking a cigarette from his case\r
+and producing a gold-latten matchbox, "the only way a woman can ever\r
+reform a man is by boring him so completely that he loses all possible\r
+interest in life. If you had married this girl, you would have been\r
+wretched. Of course, you would have treated her kindly. One can\r
+always be kind to people about whom one cares nothing. But she would\r
+have soon found out that you were absolutely indifferent to her. And\r
+when a woman finds that out about her husband, she either becomes\r
+dreadfully dowdy, or wears very smart bonnets that some other woman's\r
+husband has to pay for. I say nothing about the social mistake, which\r
+would have been abject--which, of course, I would not have allowed--but\r
+I assure you that in any case the whole thing would have been an\r
+absolute failure."\r
+\r
+"I suppose it would," muttered the lad, walking up and down the room\r
+and looking horribly pale. "But I thought it was my duty. It is not\r
+my fault that this terrible tragedy has prevented my doing what was\r
+right. I remember your saying once that there is a fatality about good\r
+resolutions--that they are always made too late. Mine certainly were."\r
+\r
+"Good resolutions are useless attempts to interfere with scientific\r
+laws. Their origin is pure vanity. Their result is absolutely _nil_.\r
+They give us, now and then, some of those luxurious sterile emotions\r
+that have a certain charm for the weak. That is all that can be said\r
+for them. They are simply cheques that men draw on a bank where they\r
+have no account."\r
+\r
+"Harry," cried Dorian Gray, coming over and sitting down beside him,\r
+"why is it that I cannot feel this tragedy as much as I want to? I\r
+don't think I am heartless. Do you?"\r
+\r
+"You have done too many foolish things during the last fortnight to be\r
+entitled to give yourself that name, Dorian," answered Lord Henry with\r
+his sweet melancholy smile.\r
+\r
+The lad frowned. "I don't like that explanation, Harry," he rejoined,\r
+"but I am glad you don't think I am heartless. I am nothing of the\r
+kind. I know I am not. And yet I must admit that this thing that has\r
+happened does not affect me as it should. It seems to me to be simply\r
+like a wonderful ending to a wonderful play. It has all the terrible\r
+beauty of a Greek tragedy, a tragedy in which I took a great part, but\r
+by which I have not been wounded."\r
+\r
+"It is an interesting question," said Lord Henry, who found an\r
+exquisite pleasure in playing on the lad's unconscious egotism, "an\r
+extremely interesting question. I fancy that the true explanation is\r
+this: It often happens that the real tragedies of life occur in such\r
+an inartistic manner that they hurt us by their crude violence, their\r
+absolute incoherence, their absurd want of meaning, their entire lack\r
+of style. They affect us just as vulgarity affects us. They give us\r
+an impression of sheer brute force, and we revolt against that.\r
+Sometimes, however, a tragedy that possesses artistic elements of\r
+beauty crosses our lives. If these elements of beauty are real, the\r
+whole thing simply appeals to our sense of dramatic effect. Suddenly\r
+we find that we are no longer the actors, but the spectators of the\r
+play. Or rather we are both. We watch ourselves, and the mere wonder\r
+of the spectacle enthralls us. In the present case, what is it that\r
+has really happened? Some one has killed herself for love of you. I\r
+wish that I had ever had such an experience. It would have made me in\r
+love with love for the rest of my life. The people who have adored\r
+me--there have not been very many, but there have been some--have\r
+always insisted on living on, long after I had ceased to care for them,\r
+or they to care for me. They have become stout and tedious, and when I\r
+meet them, they go in at once for reminiscences. That awful memory of\r
+woman! What a fearful thing it is! And what an utter intellectual\r
+stagnation it reveals! One should absorb the colour of life, but one\r
+should never remember its details. Details are always vulgar."\r
+\r
+"I must sow poppies in my garden," sighed Dorian.\r
+\r
+"There is no necessity," rejoined his companion. "Life has always\r
+poppies in her hands. Of course, now and then things linger. I once\r
+wore nothing but violets all through one season, as a form of artistic\r
+mourning for a romance that would not die. Ultimately, however, it did\r
+die. I forget what killed it. I think it was her proposing to\r
+sacrifice the whole world for me. That is always a dreadful moment.\r
+It fills one with the terror of eternity. Well--would you believe\r
+it?--a week ago, at Lady Hampshire's, I found myself seated at dinner\r
+next the lady in question, and she insisted on going over the whole\r
+thing again, and digging up the past, and raking up the future. I had\r
+buried my romance in a bed of asphodel. She dragged it out again and\r
+assured me that I had spoiled her life. I am bound to state that she\r
+ate an enormous dinner, so I did not feel any anxiety. But what a lack\r
+of taste she showed! The one charm of the past is that it is the past.\r
+But women never know when the curtain has fallen. They always want a\r
+sixth act, and as soon as the interest of the play is entirely over,\r
+they propose to continue it. If they were allowed their own way, every\r
+comedy would have a tragic ending, and every tragedy would culminate in\r
+a farce. They are charmingly artificial, but they have no sense of\r
+art. You are more fortunate than I am. I assure you, Dorian, that not\r
+one of the women I have known would have done for me what Sibyl Vane\r
+did for you. Ordinary women always console themselves. Some of them\r
+do it by going in for sentimental colours. Never trust a woman who\r
+wears mauve, whatever her age may be, or a woman over thirty-five who\r
+is fond of pink ribbons. It always means that they have a history.\r
+Others find a great consolation in suddenly discovering the good\r
+qualities of their husbands. They flaunt their conjugal felicity in\r
+one's face, as if it were the most fascinating of sins. Religion\r
+consoles some. Its mysteries have all the charm of a flirtation, a\r
+woman once told me, and I can quite understand it. Besides, nothing\r
+makes one so vain as being told that one is a sinner. Conscience makes\r
+egotists of us all. Yes; there is really no end to the consolations\r
+that women find in modern life. Indeed, I have not mentioned the most\r
+important one."\r
+\r
+"What is that, Harry?" said the lad listlessly.\r
+\r
+"Oh, the obvious consolation. Taking some one else's admirer when one\r
+loses one's own. In good society that always whitewashes a woman. But\r
+really, Dorian, how different Sibyl Vane must have been from all the\r
+women one meets! There is something to me quite beautiful about her\r
+death. I am glad I am living in a century when such wonders happen.\r
+They make one believe in the reality of the things we all play with,\r
+such as romance, passion, and love."\r
+\r
+"I was terribly cruel to her. You forget that."\r
+\r
+"I am afraid that women appreciate cruelty, downright cruelty, more\r
+than anything else. They have wonderfully primitive instincts. We\r
+have emancipated them, but they remain slaves looking for their\r
+masters, all the same. They love being dominated. I am sure you were\r
+splendid. I have never seen you really and absolutely angry, but I can\r
+fancy how delightful you looked. And, after all, you said something to\r
+me the day before yesterday that seemed to me at the time to be merely\r
+fanciful, but that I see now was absolutely true, and it holds the key\r
+to everything."\r
+\r
+"What was that, Harry?"\r
+\r
+"You said to me that Sibyl Vane represented to you all the heroines of\r
+romance--that she was Desdemona one night, and Ophelia the other; that\r
+if she died as Juliet, she came to life as Imogen."\r
+\r
+"She will never come to life again now," muttered the lad, burying his\r
+face in his hands.\r
+\r
+"No, she will never come to life. She has played her last part. But\r
+you must think of that lonely death in the tawdry dressing-room simply\r
+as a strange lurid fragment from some Jacobean tragedy, as a wonderful\r
+scene from Webster, or Ford, or Cyril Tourneur. The girl never really\r
+lived, and so she has never really died. To you at least she was\r
+always a dream, a phantom that flitted through Shakespeare's plays and\r
+left them lovelier for its presence, a reed through which Shakespeare's\r
+music sounded richer and more full of joy. The moment she touched\r
+actual life, she marred it, and it marred her, and so she passed away.\r
+Mourn for Ophelia, if you like. Put ashes on your head because\r
+Cordelia was strangled. Cry out against Heaven because the daughter of\r
+Brabantio died. But don't waste your tears over Sibyl Vane. She was\r
+less real than they are."\r
+\r
+There was a silence. The evening darkened in the room. Noiselessly,\r
+and with silver feet, the shadows crept in from the garden. The\r
+colours faded wearily out of things.\r
+\r
+After some time Dorian Gray looked up. "You have explained me to\r
+myself, Harry," he murmured with something of a sigh of relief. "I\r
+felt all that you have said, but somehow I was afraid of it, and I\r
+could not express it to myself. How well you know me! But we will not\r
+talk again of what has happened. It has been a marvellous experience.\r
+That is all. I wonder if life has still in store for me anything as\r
+marvellous."\r
+\r
+"Life has everything in store for you, Dorian. There is nothing that\r
+you, with your extraordinary good looks, will not be able to do."\r
+\r
+"But suppose, Harry, I became haggard, and old, and wrinkled? What\r
+then?"\r
+\r
+"Ah, then," said Lord Henry, rising to go, "then, my dear Dorian, you\r
+would have to fight for your victories. As it is, they are brought to\r
+you. No, you must keep your good looks. We live in an age that reads\r
+too much to be wise, and that thinks too much to be beautiful. We\r
+cannot spare you. And now you had better dress and drive down to the\r
+club. We are rather late, as it is."\r
+\r
+"I think I shall join you at the opera, Harry. I feel too tired to eat\r
+anything. What is the number of your sister's box?"\r
+\r
+"Twenty-seven, I believe. It is on the grand tier. You will see her\r
+name on the door. But I am sorry you won't come and dine."\r
+\r
+"I don't feel up to it," said Dorian listlessly. "But I am awfully\r
+obliged to you for all that you have said to me. You are certainly my\r
+best friend. No one has ever understood me as you have."\r
+\r
+"We are only at the beginning of our friendship, Dorian," answered Lord\r
+Henry, shaking him by the hand. "Good-bye. I shall see you before\r
+nine-thirty, I hope. Remember, Patti is singing."\r
+\r
+As he closed the door behind him, Dorian Gray touched the bell, and in\r
+a few minutes Victor appeared with the lamps and drew the blinds down.\r
+He waited impatiently for him to go. The man seemed to take an\r
+interminable time over everything.\r
+\r
+As soon as he had left, he rushed to the screen and drew it back. No;\r
+there was no further change in the picture. It had received the news\r
+of Sibyl Vane's death before he had known of it himself. It was\r
+conscious of the events of life as they occurred. The vicious cruelty\r
+that marred the fine lines of the mouth had, no doubt, appeared at the\r
+very moment that the girl had drunk the poison, whatever it was. Or\r
+was it indifferent to results? Did it merely take cognizance of what\r
+passed within the soul? He wondered, and hoped that some day he would\r
+see the change taking place before his very eyes, shuddering as he\r
+hoped it.\r
+\r
+Poor Sibyl! What a romance it had all been! She had often mimicked\r
+death on the stage. Then Death himself had touched her and taken her\r
+with him. How had she played that dreadful last scene? Had she cursed\r
+him, as she died? No; she had died for love of him, and love would\r
+always be a sacrament to him now. She had atoned for everything by the\r
+sacrifice she had made of her life. He would not think any more of\r
+what she had made him go through, on that horrible night at the\r
+theatre. When he thought of her, it would be as a wonderful tragic\r
+figure sent on to the world's stage to show the supreme reality of\r
+love. A wonderful tragic figure? Tears came to his eyes as he\r
+remembered her childlike look, and winsome fanciful ways, and shy\r
+tremulous grace. He brushed them away hastily and looked again at the\r
+picture.\r
+\r
+He felt that the time had really come for making his choice. Or had\r
+his choice already been made? Yes, life had decided that for\r
+him--life, and his own infinite curiosity about life. Eternal youth,\r
+infinite passion, pleasures subtle and secret, wild joys and wilder\r
+sins--he was to have all these things. The portrait was to bear the\r
+burden of his shame: that was all.\r
+\r
+A feeling of pain crept over him as he thought of the desecration that\r
+was in store for the fair face on the canvas. Once, in boyish mockery\r
+of Narcissus, he had kissed, or feigned to kiss, those painted lips\r
+that now smiled so cruelly at him. Morning after morning he had sat\r
+before the portrait wondering at its beauty, almost enamoured of it, as\r
+it seemed to him at times. Was it to alter now with every mood to\r
+which he yielded? Was it to become a monstrous and loathsome thing, to\r
+be hidden away in a locked room, to be shut out from the sunlight that\r
+had so often touched to brighter gold the waving wonder of its hair?\r
+The pity of it! the pity of it!\r
+\r
+For a moment, he thought of praying that the horrible sympathy that\r
+existed between him and the picture might cease. It had changed in\r
+answer to a prayer; perhaps in answer to a prayer it might remain\r
+unchanged. And yet, who, that knew anything about life, would\r
+surrender the chance of remaining always young, however fantastic that\r
+chance might be, or with what fateful consequences it might be fraught?\r
+Besides, was it really under his control? Had it indeed been prayer\r
+that had produced the substitution? Might there not be some curious\r
+scientific reason for it all? If thought could exercise its influence\r
+upon a living organism, might not thought exercise an influence upon\r
+dead and inorganic things? Nay, without thought or conscious desire,\r
+might not things external to ourselves vibrate in unison with our moods\r
+and passions, atom calling to atom in secret love or strange affinity?\r
+But the reason was of no importance. He would never again tempt by a\r
+prayer any terrible power. If the picture was to alter, it was to\r
+alter. That was all. Why inquire too closely into it?\r
+\r
+For there would be a real pleasure in watching it. He would be able to\r
+follow his mind into its secret places. This portrait would be to him\r
+the most magical of mirrors. As it had revealed to him his own body,\r
+so it would reveal to him his own soul. And when winter came upon it,\r
+he would still be standing where spring trembles on the verge of\r
+summer. When the blood crept from its face, and left behind a pallid\r
+mask of chalk with leaden eyes, he would keep the glamour of boyhood.\r
+Not one blossom of his loveliness would ever fade. Not one pulse of\r
+his life would ever weaken. Like the gods of the Greeks, he would be\r
+strong, and fleet, and joyous. What did it matter what happened to the\r
+coloured image on the canvas? He would be safe. That was everything.\r
+\r
+He drew the screen back into its former place in front of the picture,\r
+smiling as he did so, and passed into his bedroom, where his valet was\r
+already waiting for him. An hour later he was at the opera, and Lord\r
+Henry was leaning over his chair.\r
+\r
+\r
+\r
+CHAPTER 9\r
+\r
+As he was sitting at breakfast next morning, Basil Hallward was shown\r
+into the room.\r
+\r
+"I am so glad I have found you, Dorian," he said gravely. "I called\r
+last night, and they told me you were at the opera. Of course, I knew\r
+that was impossible. But I wish you had left word where you had really\r
+gone to. I passed a dreadful evening, half afraid that one tragedy\r
+might be followed by another. I think you might have telegraphed for\r
+me when you heard of it first. I read of it quite by chance in a late\r
+edition of _The Globe_ that I picked up at the club. I came here at once\r
+and was miserable at not finding you. I can't tell you how\r
+heart-broken I am about the whole thing. I know what you must suffer.\r
+But where were you? Did you go down and see the girl's mother? For a\r
+moment I thought of following you there. They gave the address in the\r
+paper. Somewhere in the Euston Road, isn't it? But I was afraid of\r
+intruding upon a sorrow that I could not lighten. Poor woman! What a\r
+state she must be in! And her only child, too! What did she say about\r
+it all?"\r
+\r
+"My dear Basil, how do I know?" murmured Dorian Gray, sipping some\r
+pale-yellow wine from a delicate, gold-beaded bubble of Venetian glass\r
+and looking dreadfully bored. "I was at the opera. You should have\r
+come on there. I met Lady Gwendolen, Harry's sister, for the first\r
+time. We were in her box. She is perfectly charming; and Patti sang\r
+divinely. Don't talk about horrid subjects. If one doesn't talk about\r
+a thing, it has never happened. It is simply expression, as Harry\r
+says, that gives reality to things. I may mention that she was not the\r
+woman's only child. There is a son, a charming fellow, I believe. But\r
+he is not on the stage. He is a sailor, or something. And now, tell\r
+me about yourself and what you are painting."\r
+\r
+"You went to the opera?" said Hallward, speaking very slowly and with a\r
+strained touch of pain in his voice. "You went to the opera while\r
+Sibyl Vane was lying dead in some sordid lodging? You can talk to me\r
+of other women being charming, and of Patti singing divinely, before\r
+the girl you loved has even the quiet of a grave to sleep in? Why,\r
+man, there are horrors in store for that little white body of hers!"\r
+\r
+"Stop, Basil! I won't hear it!" cried Dorian, leaping to his feet.\r
+"You must not tell me about things. What is done is done. What is\r
+past is past."\r
+\r
+"You call yesterday the past?"\r
+\r
+"What has the actual lapse of time got to do with it? It is only\r
+shallow people who require years to get rid of an emotion. A man who\r
+is master of himself can end a sorrow as easily as he can invent a\r
+pleasure. I don't want to be at the mercy of my emotions. I want to\r
+use them, to enjoy them, and to dominate them."\r
+\r
+"Dorian, this is horrible! Something has changed you completely. You\r
+look exactly the same wonderful boy who, day after day, used to come\r
+down to my studio to sit for his picture. But you were simple,\r
+natural, and affectionate then. You were the most unspoiled creature\r
+in the whole world. Now, I don't know what has come over you. You\r
+talk as if you had no heart, no pity in you. It is all Harry's\r
+influence. I see that."\r
+\r
+The lad flushed up and, going to the window, looked out for a few\r
+moments on the green, flickering, sun-lashed garden. "I owe a great\r
+deal to Harry, Basil," he said at last, "more than I owe to you. You\r
+only taught me to be vain."\r
+\r
+"Well, I am punished for that, Dorian--or shall be some day."\r
+\r
+"I don't know what you mean, Basil," he exclaimed, turning round. "I\r
+don't know what you want. What do you want?"\r
+\r
+"I want the Dorian Gray I used to paint," said the artist sadly.\r
+\r
+"Basil," said the lad, going over to him and putting his hand on his\r
+shoulder, "you have come too late. Yesterday, when I heard that Sibyl\r
+Vane had killed herself--"\r
+\r
+"Killed herself! Good heavens! is there no doubt about that?" cried\r
+Hallward, looking up at him with an expression of horror.\r
+\r
+"My dear Basil! Surely you don't think it was a vulgar accident? Of\r
+course she killed herself."\r
+\r
+The elder man buried his face in his hands. "How fearful," he\r
+muttered, and a shudder ran through him.\r
+\r
+"No," said Dorian Gray, "there is nothing fearful about it. It is one\r
+of the great romantic tragedies of the age. As a rule, people who act\r
+lead the most commonplace lives. They are good husbands, or faithful\r
+wives, or something tedious. You know what I mean--middle-class virtue\r
+and all that kind of thing. How different Sibyl was! She lived her\r
+finest tragedy. She was always a heroine. The last night she\r
+played--the night you saw her--she acted badly because she had known\r
+the reality of love. When she knew its unreality, she died, as Juliet\r
+might have died. She passed again into the sphere of art. There is\r
+something of the martyr about her. Her death has all the pathetic\r
+uselessness of martyrdom, all its wasted beauty. But, as I was saying,\r
+you must not think I have not suffered. If you had come in yesterday\r
+at a particular moment--about half-past five, perhaps, or a quarter to\r
+six--you would have found me in tears. Even Harry, who was here, who\r
+brought me the news, in fact, had no idea what I was going through. I\r
+suffered immensely. Then it passed away. I cannot repeat an emotion.\r
+No one can, except sentimentalists. And you are awfully unjust, Basil.\r
+You come down here to console me. That is charming of you. You find\r
+me consoled, and you are furious. How like a sympathetic person! You\r
+remind me of a story Harry told me about a certain philanthropist who\r
+spent twenty years of his life in trying to get some grievance\r
+redressed, or some unjust law altered--I forget exactly what it was.\r
+Finally he succeeded, and nothing could exceed his disappointment. He\r
+had absolutely nothing to do, almost died of _ennui_, and became a\r
+confirmed misanthrope. And besides, my dear old Basil, if you really\r
+want to console me, teach me rather to forget what has happened, or to\r
+see it from a proper artistic point of view. Was it not Gautier who\r
+used to write about _la consolation des arts_? I remember picking up a\r
+little vellum-covered book in your studio one day and chancing on that\r
+delightful phrase. Well, I am not like that young man you told me of\r
+when we were down at Marlow together, the young man who used to say\r
+that yellow satin could console one for all the miseries of life. I\r
+love beautiful things that one can touch and handle. Old brocades,\r
+green bronzes, lacquer-work, carved ivories, exquisite surroundings,\r
+luxury, pomp--there is much to be got from all these. But the artistic\r
+temperament that they create, or at any rate reveal, is still more to\r
+me. To become the spectator of one's own life, as Harry says, is to\r
+escape the suffering of life. I know you are surprised at my talking\r
+to you like this. You have not realized how I have developed. I was a\r
+schoolboy when you knew me. I am a man now. I have new passions, new\r
+thoughts, new ideas. I am different, but you must not like me less. I\r
+am changed, but you must always be my friend. Of course, I am very\r
+fond of Harry. But I know that you are better than he is. You are not\r
+stronger--you are too much afraid of life--but you are better. And how\r
+happy we used to be together! Don't leave me, Basil, and don't quarrel\r
+with me. I am what I am. There is nothing more to be said."\r
+\r
+The painter felt strangely moved. The lad was infinitely dear to him,\r
+and his personality had been the great turning point in his art. He\r
+could not bear the idea of reproaching him any more. After all, his\r
+indifference was probably merely a mood that would pass away. There\r
+was so much in him that was good, so much in him that was noble.\r
+\r
+"Well, Dorian," he said at length, with a sad smile, "I won't speak to\r
+you again about this horrible thing, after to-day. I only trust your\r
+name won't be mentioned in connection with it. The inquest is to take\r
+place this afternoon. Have they summoned you?"\r
+\r
+Dorian shook his head, and a look of annoyance passed over his face at\r
+the mention of the word "inquest." There was something so crude and\r
+vulgar about everything of the kind. "They don't know my name," he\r
+answered.\r
+\r
+"But surely she did?"\r
+\r
+"Only my Christian name, and that I am quite sure she never mentioned\r
+to any one. She told me once that they were all rather curious to\r
+learn who I was, and that she invariably told them my name was Prince\r
+Charming. It was pretty of her. You must do me a drawing of Sibyl,\r
+Basil. I should like to have something more of her than the memory of\r
+a few kisses and some broken pathetic words."\r
+\r
+"I will try and do something, Dorian, if it would please you. But you\r
+must come and sit to me yourself again. I can't get on without you."\r
+\r
+"I can never sit to you again, Basil. It is impossible!" he exclaimed,\r
+starting back.\r
+\r
+The painter stared at him. "My dear boy, what nonsense!" he cried.\r
+"Do you mean to say you don't like what I did of you? Where is it?\r
+Why have you pulled the screen in front of it? Let me look at it. It\r
+is the best thing I have ever done. Do take the screen away, Dorian.\r
+It is simply disgraceful of your servant hiding my work like that. I\r
+felt the room looked different as I came in."\r
+\r
+"My servant has nothing to do with it, Basil. You don't imagine I let\r
+him arrange my room for me? He settles my flowers for me\r
+sometimes--that is all. No; I did it myself. The light was too strong\r
+on the portrait."\r
+\r
+"Too strong! Surely not, my dear fellow? It is an admirable place for\r
+it. Let me see it." And Hallward walked towards the corner of the\r
+room.\r
+\r
+A cry of terror broke from Dorian Gray's lips, and he rushed between\r
+the painter and the screen. "Basil," he said, looking very pale, "you\r
+must not look at it. I don't wish you to."\r
+\r
+"Not look at my own work! You are not serious. Why shouldn't I look\r
+at it?" exclaimed Hallward, laughing.\r
+\r
+"If you try to look at it, Basil, on my word of honour I will never\r
+speak to you again as long as I live. I am quite serious. I don't\r
+offer any explanation, and you are not to ask for any. But, remember,\r
+if you touch this screen, everything is over between us."\r
+\r
+Hallward was thunderstruck. He looked at Dorian Gray in absolute\r
+amazement. He had never seen him like this before. The lad was\r
+actually pallid with rage. His hands were clenched, and the pupils of\r
+his eyes were like disks of blue fire. He was trembling all over.\r
+\r
+"Dorian!"\r
+\r
+"Don't speak!"\r
+\r
+"But what is the matter? Of course I won't look at it if you don't\r
+want me to," he said, rather coldly, turning on his heel and going over\r
+towards the window. "But, really, it seems rather absurd that I\r
+shouldn't see my own work, especially as I am going to exhibit it in\r
+Paris in the autumn. I shall probably have to give it another coat of\r
+varnish before that, so I must see it some day, and why not to-day?"\r
+\r
+"To exhibit it! You want to exhibit it?" exclaimed Dorian Gray, a\r
+strange sense of terror creeping over him. Was the world going to be\r
+shown his secret? Were people to gape at the mystery of his life?\r
+That was impossible. Something--he did not know what--had to be done\r
+at once.\r
+\r
+"Yes; I don't suppose you will object to that. Georges Petit is going\r
+to collect all my best pictures for a special exhibition in the Rue de\r
+Seze, which will open the first week in October. The portrait will\r
+only be away a month. I should think you could easily spare it for\r
+that time. In fact, you are sure to be out of town. And if you keep\r
+it always behind a screen, you can't care much about it."\r
+\r
+Dorian Gray passed his hand over his forehead. There were beads of\r
+perspiration there. He felt that he was on the brink of a horrible\r
+danger. "You told me a month ago that you would never exhibit it," he\r
+cried. "Why have you changed your mind? You people who go in for\r
+being consistent have just as many moods as others have. The only\r
+difference is that your moods are rather meaningless. You can't have\r
+forgotten that you assured me most solemnly that nothing in the world\r
+would induce you to send it to any exhibition. You told Harry exactly\r
+the same thing." He stopped suddenly, and a gleam of light came into\r
+his eyes. He remembered that Lord Henry had said to him once, half\r
+seriously and half in jest, "If you want to have a strange quarter of\r
+an hour, get Basil to tell you why he won't exhibit your picture. He\r
+told me why he wouldn't, and it was a revelation to me." Yes, perhaps\r
+Basil, too, had his secret. He would ask him and try.\r
+\r
+"Basil," he said, coming over quite close and looking him straight in\r
+the face, "we have each of us a secret. Let me know yours, and I shall\r
+tell you mine. What was your reason for refusing to exhibit my\r
+picture?"\r
+\r
+The painter shuddered in spite of himself. "Dorian, if I told you, you\r
+might like me less than you do, and you would certainly laugh at me. I\r
+could not bear your doing either of those two things. If you wish me\r
+never to look at your picture again, I am content. I have always you\r
+to look at. If you wish the best work I have ever done to be hidden\r
+from the world, I am satisfied. Your friendship is dearer to me than\r
+any fame or reputation."\r
+\r
+"No, Basil, you must tell me," insisted Dorian Gray. "I think I have a\r
+right to know." His feeling of terror had passed away, and curiosity\r
+had taken its place. He was determined to find out Basil Hallward's\r
+mystery.\r
+\r
+"Let us sit down, Dorian," said the painter, looking troubled. "Let us\r
+sit down. And just answer me one question. Have you noticed in the\r
+picture something curious?--something that probably at first did not\r
+strike you, but that revealed itself to you suddenly?"\r
+\r
+"Basil!" cried the lad, clutching the arms of his chair with trembling\r
+hands and gazing at him with wild startled eyes.\r
+\r
+"I see you did. Don't speak. Wait till you hear what I have to say.\r
+Dorian, from the moment I met you, your personality had the most\r
+extraordinary influence over me. I was dominated, soul, brain, and\r
+power, by you. You became to me the visible incarnation of that unseen\r
+ideal whose memory haunts us artists like an exquisite dream. I\r
+worshipped you. I grew jealous of every one to whom you spoke. I\r
+wanted to have you all to myself. I was only happy when I was with\r
+you. When you were away from me, you were still present in my art....\r
+Of course, I never let you know anything about this. It would have\r
+been impossible. You would not have understood it. I hardly\r
+understood it myself. I only knew that I had seen perfection face to\r
+face, and that the world had become wonderful to my eyes--too\r
+wonderful, perhaps, for in such mad worships there is peril, the peril\r
+of losing them, no less than the peril of keeping them.... Weeks and\r
+weeks went on, and I grew more and more absorbed in you. Then came a\r
+new development. I had drawn you as Paris in dainty armour, and as\r
+Adonis with huntsman's cloak and polished boar-spear. Crowned with\r
+heavy lotus-blossoms you had sat on the prow of Adrian's barge, gazing\r
+across the green turbid Nile. You had leaned over the still pool of\r
+some Greek woodland and seen in the water's silent silver the marvel of\r
+your own face. And it had all been what art should be--unconscious,\r
+ideal, and remote. One day, a fatal day I sometimes think, I\r
+determined to paint a wonderful portrait of you as you actually are,\r
+not in the costume of dead ages, but in your own dress and in your own\r
+time. Whether it was the realism of the method, or the mere wonder of\r
+your own personality, thus directly presented to me without mist or\r
+veil, I cannot tell. But I know that as I worked at it, every flake\r
+and film of colour seemed to me to reveal my secret. I grew afraid\r
+that others would know of my idolatry. I felt, Dorian, that I had told\r
+too much, that I had put too much of myself into it. Then it was that\r
+I resolved never to allow the picture to be exhibited. You were a\r
+little annoyed; but then you did not realize all that it meant to me.\r
+Harry, to whom I talked about it, laughed at me. But I did not mind\r
+that. When the picture was finished, and I sat alone with it, I felt\r
+that I was right.... Well, after a few days the thing left my studio,\r
+and as soon as I had got rid of the intolerable fascination of its\r
+presence, it seemed to me that I had been foolish in imagining that I\r
+had seen anything in it, more than that you were extremely good-looking\r
+and that I could paint. Even now I cannot help feeling that it is a\r
+mistake to think that the passion one feels in creation is ever really\r
+shown in the work one creates. Art is always more abstract than we\r
+fancy. Form and colour tell us of form and colour--that is all. It\r
+often seems to me that art conceals the artist far more completely than\r
+it ever reveals him. And so when I got this offer from Paris, I\r
+determined to make your portrait the principal thing in my exhibition.\r
+It never occurred to me that you would refuse. I see now that you were\r
+right. The picture cannot be shown. You must not be angry with me,\r
+Dorian, for what I have told you. As I said to Harry, once, you are\r
+made to be worshipped."\r
+\r
+Dorian Gray drew a long breath. The colour came back to his cheeks,\r
+and a smile played about his lips. The peril was over. He was safe\r
+for the time. Yet he could not help feeling infinite pity for the\r
+painter who had just made this strange confession to him, and wondered\r
+if he himself would ever be so dominated by the personality of a\r
+friend. Lord Henry had the charm of being very dangerous. But that\r
+was all. He was too clever and too cynical to be really fond of.\r
+Would there ever be some one who would fill him with a strange\r
+idolatry? Was that one of the things that life had in store?\r
+\r
+"It is extraordinary to me, Dorian," said Hallward, "that you should\r
+have seen this in the portrait. Did you really see it?"\r
+\r
+"I saw something in it," he answered, "something that seemed to me very\r
+curious."\r
+\r
+"Well, you don't mind my looking at the thing now?"\r
+\r
+Dorian shook his head. "You must not ask me that, Basil. I could not\r
+possibly let you stand in front of that picture."\r
+\r
+"You will some day, surely?"\r
+\r
+"Never."\r
+\r
+"Well, perhaps you are right. And now good-bye, Dorian. You have been\r
+the one person in my life who has really influenced my art. Whatever I\r
+have done that is good, I owe to you. Ah! you don't know what it cost\r
+me to tell you all that I have told you."\r
+\r
+"My dear Basil," said Dorian, "what have you told me? Simply that you\r
+felt that you admired me too much. That is not even a compliment."\r
+\r
+"It was not intended as a compliment. It was a confession. Now that I\r
+have made it, something seems to have gone out of me. Perhaps one\r
+should never put one's worship into words."\r
+\r
+"It was a very disappointing confession."\r
+\r
+"Why, what did you expect, Dorian? You didn't see anything else in the\r
+picture, did you? There was nothing else to see?"\r
+\r
+"No; there was nothing else to see. Why do you ask? But you mustn't\r
+talk about worship. It is foolish. You and I are friends, Basil, and\r
+we must always remain so."\r
+\r
+"You have got Harry," said the painter sadly.\r
+\r
+"Oh, Harry!" cried the lad, with a ripple of laughter. "Harry spends\r
+his days in saying what is incredible and his evenings in doing what is\r
+improbable. Just the sort of life I would like to lead. But still I\r
+don't think I would go to Harry if I were in trouble. I would sooner\r
+go to you, Basil."\r
+\r
+"You will sit to me again?"\r
+\r
+"Impossible!"\r
+\r
+"You spoil my life as an artist by refusing, Dorian. No man comes\r
+across two ideal things. Few come across one."\r
+\r
+"I can't explain it to you, Basil, but I must never sit to you again.\r
+There is something fatal about a portrait. It has a life of its own.\r
+I will come and have tea with you. That will be just as pleasant."\r
+\r
+"Pleasanter for you, I am afraid," murmured Hallward regretfully. "And\r
+now good-bye. I am sorry you won't let me look at the picture once\r
+again. But that can't be helped. I quite understand what you feel\r
+about it."\r
+\r
+As he left the room, Dorian Gray smiled to himself. Poor Basil! How\r
+little he knew of the true reason! And how strange it was that,\r
+instead of having been forced to reveal his own secret, he had\r
+succeeded, almost by chance, in wresting a secret from his friend! How\r
+much that strange confession explained to him! The painter's absurd\r
+fits of jealousy, his wild devotion, his extravagant panegyrics, his\r
+curious reticences--he understood them all now, and he felt sorry.\r
+There seemed to him to be something tragic in a friendship so coloured\r
+by romance.\r
+\r
+He sighed and touched the bell. The portrait must be hidden away at\r
+all costs. He could not run such a risk of discovery again. It had\r
+been mad of him to have allowed the thing to remain, even for an hour,\r
+in a room to which any of his friends had access.\r
+\r
+\r
+\r
+CHAPTER 10\r
+\r
+When his servant entered, he looked at him steadfastly and wondered if\r
+he had thought of peering behind the screen. The man was quite\r
+impassive and waited for his orders. Dorian lit a cigarette and walked\r
+over to the glass and glanced into it. He could see the reflection of\r
+Victor's face perfectly. It was like a placid mask of servility.\r
+There was nothing to be afraid of, there. Yet he thought it best to be\r
+on his guard.\r
+\r
+Speaking very slowly, he told him to tell the house-keeper that he\r
+wanted to see her, and then to go to the frame-maker and ask him to\r
+send two of his men round at once. It seemed to him that as the man\r
+left the room his eyes wandered in the direction of the screen. Or was\r
+that merely his own fancy?\r
+\r
+After a few moments, in her black silk dress, with old-fashioned thread\r
+mittens on her wrinkled hands, Mrs. Leaf bustled into the library. He\r
+asked her for the key of the schoolroom.\r
+\r
+"The old schoolroom, Mr. Dorian?" she exclaimed. "Why, it is full of\r
+dust. I must get it arranged and put straight before you go into it.\r
+It is not fit for you to see, sir. It is not, indeed."\r
+\r
+"I don't want it put straight, Leaf. I only want the key."\r
+\r
+"Well, sir, you'll be covered with cobwebs if you go into it. Why, it\r
+hasn't been opened for nearly five years--not since his lordship died."\r
+\r
+He winced at the mention of his grandfather. He had hateful memories\r
+of him. "That does not matter," he answered. "I simply want to see\r
+the place--that is all. Give me the key."\r
+\r
+"And here is the key, sir," said the old lady, going over the contents\r
+of her bunch with tremulously uncertain hands. "Here is the key. I'll\r
+have it off the bunch in a moment. But you don't think of living up\r
+there, sir, and you so comfortable here?"\r
+\r
+"No, no," he cried petulantly. "Thank you, Leaf. That will do."\r
+\r
+She lingered for a few moments, and was garrulous over some detail of\r
+the household. He sighed and told her to manage things as she thought\r
+best. She left the room, wreathed in smiles.\r
+\r
+As the door closed, Dorian put the key in his pocket and looked round\r
+the room. His eye fell on a large, purple satin coverlet heavily\r
+embroidered with gold, a splendid piece of late seventeenth-century\r
+Venetian work that his grandfather had found in a convent near Bologna.\r
+Yes, that would serve to wrap the dreadful thing in. It had perhaps\r
+served often as a pall for the dead. Now it was to hide something that\r
+had a corruption of its own, worse than the corruption of death\r
+itself--something that would breed horrors and yet would never die.\r
+What the worm was to the corpse, his sins would be to the painted image\r
+on the canvas. They would mar its beauty and eat away its grace. They\r
+would defile it and make it shameful. And yet the thing would still\r
+live on. It would be always alive.\r
+\r
+He shuddered, and for a moment he regretted that he had not told Basil\r
+the true reason why he had wished to hide the picture away. Basil\r
+would have helped him to resist Lord Henry's influence, and the still\r
+more poisonous influences that came from his own temperament. The love\r
+that he bore him--for it was really love--had nothing in it that was\r
+not noble and intellectual. It was not that mere physical admiration\r
+of beauty that is born of the senses and that dies when the senses\r
+tire. It was such love as Michelangelo had known, and Montaigne, and\r
+Winckelmann, and Shakespeare himself. Yes, Basil could have saved him.\r
+But it was too late now. The past could always be annihilated.\r
+Regret, denial, or forgetfulness could do that. But the future was\r
+inevitable. There were passions in him that would find their terrible\r
+outlet, dreams that would make the shadow of their evil real.\r
+\r
+He took up from the couch the great purple-and-gold texture that\r
+covered it, and, holding it in his hands, passed behind the screen.\r
+Was the face on the canvas viler than before? It seemed to him that it\r
+was unchanged, and yet his loathing of it was intensified. Gold hair,\r
+blue eyes, and rose-red lips--they all were there. It was simply the\r
+expression that had altered. That was horrible in its cruelty.\r
+Compared to what he saw in it of censure or rebuke, how shallow Basil's\r
+reproaches about Sibyl Vane had been!--how shallow, and of what little\r
+account! His own soul was looking out at him from the canvas and\r
+calling him to judgement. A look of pain came across him, and he flung\r
+the rich pall over the picture. As he did so, a knock came to the\r
+door. He passed out as his servant entered.\r
+\r
+"The persons are here, Monsieur."\r
+\r
+He felt that the man must be got rid of at once. He must not be\r
+allowed to know where the picture was being taken to. There was\r
+something sly about him, and he had thoughtful, treacherous eyes.\r
+Sitting down at the writing-table he scribbled a note to Lord Henry,\r
+asking him to send him round something to read and reminding him that\r
+they were to meet at eight-fifteen that evening.\r
+\r
+"Wait for an answer," he said, handing it to him, "and show the men in\r
+here."\r
+\r
+In two or three minutes there was another knock, and Mr. Hubbard\r
+himself, the celebrated frame-maker of South Audley Street, came in\r
+with a somewhat rough-looking young assistant. Mr. Hubbard was a\r
+florid, red-whiskered little man, whose admiration for art was\r
+considerably tempered by the inveterate impecuniosity of most of the\r
+artists who dealt with him. As a rule, he never left his shop. He\r
+waited for people to come to him. But he always made an exception in\r
+favour of Dorian Gray. There was something about Dorian that charmed\r
+everybody. It was a pleasure even to see him.\r
+\r
+"What can I do for you, Mr. Gray?" he said, rubbing his fat freckled\r
+hands. "I thought I would do myself the honour of coming round in\r
+person. I have just got a beauty of a frame, sir. Picked it up at a\r
+sale. Old Florentine. Came from Fonthill, I believe. Admirably\r
+suited for a religious subject, Mr. Gray."\r
+\r
+"I am so sorry you have given yourself the trouble of coming round, Mr.\r
+Hubbard. I shall certainly drop in and look at the frame--though I\r
+don't go in much at present for religious art--but to-day I only want a\r
+picture carried to the top of the house for me. It is rather heavy, so\r
+I thought I would ask you to lend me a couple of your men."\r
+\r
+"No trouble at all, Mr. Gray. I am delighted to be of any service to\r
+you. Which is the work of art, sir?"\r
+\r
+"This," replied Dorian, moving the screen back. "Can you move it,\r
+covering and all, just as it is? I don't want it to get scratched\r
+going upstairs."\r
+\r
+"There will be no difficulty, sir," said the genial frame-maker,\r
+beginning, with the aid of his assistant, to unhook the picture from\r
+the long brass chains by which it was suspended. "And, now, where\r
+shall we carry it to, Mr. Gray?"\r
+\r
+"I will show you the way, Mr. Hubbard, if you will kindly follow me.\r
+Or perhaps you had better go in front. I am afraid it is right at the\r
+top of the house. We will go up by the front staircase, as it is\r
+wider."\r
+\r
+He held the door open for them, and they passed out into the hall and\r
+began the ascent. The elaborate character of the frame had made the\r
+picture extremely bulky, and now and then, in spite of the obsequious\r
+protests of Mr. Hubbard, who had the true tradesman's spirited dislike\r
+of seeing a gentleman doing anything useful, Dorian put his hand to it\r
+so as to help them.\r
+\r
+"Something of a load to carry, sir," gasped the little man when they\r
+reached the top landing. And he wiped his shiny forehead.\r
+\r
+"I am afraid it is rather heavy," murmured Dorian as he unlocked the\r
+door that opened into the room that was to keep for him the curious\r
+secret of his life and hide his soul from the eyes of men.\r
+\r
+He had not entered the place for more than four years--not, indeed,\r
+since he had used it first as a play-room when he was a child, and then\r
+as a study when he grew somewhat older. It was a large,\r
+well-proportioned room, which had been specially built by the last Lord\r
+Kelso for the use of the little grandson whom, for his strange likeness\r
+to his mother, and also for other reasons, he had always hated and\r
+desired to keep at a distance. It appeared to Dorian to have but\r
+little changed. There was the huge Italian _cassone_, with its\r
+fantastically painted panels and its tarnished gilt mouldings, in which\r
+he had so often hidden himself as a boy. There the satinwood book-case\r
+filled with his dog-eared schoolbooks. On the wall behind it was\r
+hanging the same ragged Flemish tapestry where a faded king and queen\r
+were playing chess in a garden, while a company of hawkers rode by,\r
+carrying hooded birds on their gauntleted wrists. How well he\r
+remembered it all! Every moment of his lonely childhood came back to\r
+him as he looked round. He recalled the stainless purity of his boyish\r
+life, and it seemed horrible to him that it was here the fatal portrait\r
+was to be hidden away. How little he had thought, in those dead days,\r
+of all that was in store for him!\r
+\r
+But there was no other place in the house so secure from prying eyes as\r
+this. He had the key, and no one else could enter it. Beneath its\r
+purple pall, the face painted on the canvas could grow bestial, sodden,\r
+and unclean. What did it matter? No one could see it. He himself\r
+would not see it. Why should he watch the hideous corruption of his\r
+soul? He kept his youth--that was enough. And, besides, might not\r
+his nature grow finer, after all? There was no reason that the future\r
+should be so full of shame. Some love might come across his life, and\r
+purify him, and shield him from those sins that seemed to be already\r
+stirring in spirit and in flesh--those curious unpictured sins whose\r
+very mystery lent them their subtlety and their charm. Perhaps, some\r
+day, the cruel look would have passed away from the scarlet sensitive\r
+mouth, and he might show to the world Basil Hallward's masterpiece.\r
+\r
+No; that was impossible. Hour by hour, and week by week, the thing\r
+upon the canvas was growing old. It might escape the hideousness of\r
+sin, but the hideousness of age was in store for it. The cheeks would\r
+become hollow or flaccid. Yellow crow's feet would creep round the\r
+fading eyes and make them horrible. The hair would lose its\r
+brightness, the mouth would gape or droop, would be foolish or gross,\r
+as the mouths of old men are. There would be the wrinkled throat, the\r
+cold, blue-veined hands, the twisted body, that he remembered in the\r
+grandfather who had been so stern to him in his boyhood. The picture\r
+had to be concealed. There was no help for it.\r
+\r
+"Bring it in, Mr. Hubbard, please," he said, wearily, turning round.\r
+"I am sorry I kept you so long. I was thinking of something else."\r
+\r
+"Always glad to have a rest, Mr. Gray," answered the frame-maker, who\r
+was still gasping for breath. "Where shall we put it, sir?"\r
+\r
+"Oh, anywhere. Here: this will do. I don't want to have it hung up.\r
+Just lean it against the wall. Thanks."\r
+\r
+"Might one look at the work of art, sir?"\r
+\r
+Dorian started. "It would not interest you, Mr. Hubbard," he said,\r
+keeping his eye on the man. He felt ready to leap upon him and fling\r
+him to the ground if he dared to lift the gorgeous hanging that\r
+concealed the secret of his life. "I shan't trouble you any more now.\r
+I am much obliged for your kindness in coming round."\r
+\r
+"Not at all, not at all, Mr. Gray. Ever ready to do anything for you,\r
+sir." And Mr. Hubbard tramped downstairs, followed by the assistant,\r
+who glanced back at Dorian with a look of shy wonder in his rough\r
+uncomely face. He had never seen any one so marvellous.\r
+\r
+When the sound of their footsteps had died away, Dorian locked the door\r
+and put the key in his pocket. He felt safe now. No one would ever\r
+look upon the horrible thing. No eye but his would ever see his shame.\r
+\r
+On reaching the library, he found that it was just after five o'clock\r
+and that the tea had been already brought up. On a little table of\r
+dark perfumed wood thickly incrusted with nacre, a present from Lady\r
+Radley, his guardian's wife, a pretty professional invalid who had\r
+spent the preceding winter in Cairo, was lying a note from Lord Henry,\r
+and beside it was a book bound in yellow paper, the cover slightly torn\r
+and the edges soiled. A copy of the third edition of _The St. James's\r
+Gazette_ had been placed on the tea-tray. It was evident that Victor had\r
+returned. He wondered if he had met the men in the hall as they were\r
+leaving the house and had wormed out of them what they had been doing.\r
+He would be sure to miss the picture--had no doubt missed it already,\r
+while he had been laying the tea-things. The screen had not been set\r
+back, and a blank space was visible on the wall. Perhaps some night he\r
+might find him creeping upstairs and trying to force the door of the\r
+room. It was a horrible thing to have a spy in one's house. He had\r
+heard of rich men who had been blackmailed all their lives by some\r
+servant who had read a letter, or overheard a conversation, or picked\r
+up a card with an address, or found beneath a pillow a withered flower\r
+or a shred of crumpled lace.\r
+\r
+He sighed, and having poured himself out some tea, opened Lord Henry's\r
+note. It was simply to say that he sent him round the evening paper,\r
+and a book that might interest him, and that he would be at the club at\r
+eight-fifteen. He opened _The St. James's_ languidly, and looked through\r
+it. A red pencil-mark on the fifth page caught his eye. It drew\r
+attention to the following paragraph:\r
+\r
+\r
+INQUEST ON AN ACTRESS.--An inquest was held this morning at the Bell\r
+Tavern, Hoxton Road, by Mr. Danby, the District Coroner, on the body of\r
+Sibyl Vane, a young actress recently engaged at the Royal Theatre,\r
+Holborn. A verdict of death by misadventure was returned.\r
+Considerable sympathy was expressed for the mother of the deceased, who\r
+was greatly affected during the giving of her own evidence, and that of\r
+Dr. Birrell, who had made the post-mortem examination of the deceased.\r
+\r
+\r
+He frowned, and tearing the paper in two, went across the room and\r
+flung the pieces away. How ugly it all was! And how horribly real\r
+ugliness made things! He felt a little annoyed with Lord Henry for\r
+having sent him the report. And it was certainly stupid of him to have\r
+marked it with red pencil. Victor might have read it. The man knew\r
+more than enough English for that.\r
+\r
+Perhaps he had read it and had begun to suspect something. And, yet,\r
+what did it matter? What had Dorian Gray to do with Sibyl Vane's\r
+death? There was nothing to fear. Dorian Gray had not killed her.\r
+\r
+His eye fell on the yellow book that Lord Henry had sent him. What was\r
+it, he wondered. He went towards the little, pearl-coloured octagonal\r
+stand that had always looked to him like the work of some strange\r
+Egyptian bees that wrought in silver, and taking up the volume, flung\r
+himself into an arm-chair and began to turn over the leaves. After a\r
+few minutes he became absorbed. It was the strangest book that he had\r
+ever read. It seemed to him that in exquisite raiment, and to the\r
+delicate sound of flutes, the sins of the world were passing in dumb\r
+show before him. Things that he had dimly dreamed of were suddenly\r
+made real to him. Things of which he had never dreamed were gradually\r
+revealed.\r
+\r
+It was a novel without a plot and with only one character, being,\r
+indeed, simply a psychological study of a certain young Parisian who\r
+spent his life trying to realize in the nineteenth century all the\r
+passions and modes of thought that belonged to every century except his\r
+own, and to sum up, as it were, in himself the various moods through\r
+which the world-spirit had ever passed, loving for their mere\r
+artificiality those renunciations that men have unwisely called virtue,\r
+as much as those natural rebellions that wise men still call sin. The\r
+style in which it was written was that curious jewelled style, vivid\r
+and obscure at once, full of _argot_ and of archaisms, of technical\r
+expressions and of elaborate paraphrases, that characterizes the work\r
+of some of the finest artists of the French school of _Symbolistes_.\r
+There were in it metaphors as monstrous as orchids and as subtle in\r
+colour. The life of the senses was described in the terms of mystical\r
+philosophy. One hardly knew at times whether one was reading the\r
+spiritual ecstasies of some mediaeval saint or the morbid confessions\r
+of a modern sinner. It was a poisonous book. The heavy odour of\r
+incense seemed to cling about its pages and to trouble the brain. The\r
+mere cadence of the sentences, the subtle monotony of their music, so\r
+full as it was of complex refrains and movements elaborately repeated,\r
+produced in the mind of the lad, as he passed from chapter to chapter,\r
+a form of reverie, a malady of dreaming, that made him unconscious of\r
+the falling day and creeping shadows.\r
+\r
+Cloudless, and pierced by one solitary star, a copper-green sky gleamed\r
+through the windows. He read on by its wan light till he could read no\r
+more. Then, after his valet had reminded him several times of the\r
+lateness of the hour, he got up, and going into the next room, placed\r
+the book on the little Florentine table that always stood at his\r
+bedside and began to dress for dinner.\r
+\r
+It was almost nine o'clock before he reached the club, where he found\r
+Lord Henry sitting alone, in the morning-room, looking very much bored.\r
+\r
+"I am so sorry, Harry," he cried, "but really it is entirely your\r
+fault. That book you sent me so fascinated me that I forgot how the\r
+time was going."\r
+\r
+"Yes, I thought you would like it," replied his host, rising from his\r
+chair.\r
+\r
+"I didn't say I liked it, Harry. I said it fascinated me. There is a\r
+great difference."\r
+\r
+"Ah, you have discovered that?" murmured Lord Henry. And they passed\r
+into the dining-room.\r
+\r
+\r
+\r
+CHAPTER 11\r
+\r
+For years, Dorian Gray could not free himself from the influence of\r
+this book. Or perhaps it would be more accurate to say that he never\r
+sought to free himself from it. He procured from Paris no less than\r
+nine large-paper copies of the first edition, and had them bound in\r
+different colours, so that they might suit his various moods and the\r
+changing fancies of a nature over which he seemed, at times, to have\r
+almost entirely lost control. The hero, the wonderful young Parisian\r
+in whom the romantic and the scientific temperaments were so strangely\r
+blended, became to him a kind of prefiguring type of himself. And,\r
+indeed, the whole book seemed to him to contain the story of his own\r
+life, written before he had lived it.\r
+\r
+In one point he was more fortunate than the novel's fantastic hero. He\r
+never knew--never, indeed, had any cause to know--that somewhat\r
+grotesque dread of mirrors, and polished metal surfaces, and still\r
+water which came upon the young Parisian so early in his life, and was\r
+occasioned by the sudden decay of a beau that had once, apparently,\r
+been so remarkable. It was with an almost cruel joy--and perhaps in\r
+nearly every joy, as certainly in every pleasure, cruelty has its\r
+place--that he used to read the latter part of the book, with its\r
+really tragic, if somewhat overemphasized, account of the sorrow and\r
+despair of one who had himself lost what in others, and the world, he\r
+had most dearly valued.\r
+\r
+For the wonderful beauty that had so fascinated Basil Hallward, and\r
+many others besides him, seemed never to leave him. Even those who had\r
+heard the most evil things against him--and from time to time strange\r
+rumours about his mode of life crept through London and became the\r
+chatter of the clubs--could not believe anything to his dishonour when\r
+they saw him. He had always the look of one who had kept himself\r
+unspotted from the world. Men who talked grossly became silent when\r
+Dorian Gray entered the room. There was something in the purity of his\r
+face that rebuked them. His mere presence seemed to recall to them the\r
+memory of the innocence that they had tarnished. They wondered how one\r
+so charming and graceful as he was could have escaped the stain of an\r
+age that was at once sordid and sensual.\r
+\r
+Often, on returning home from one of those mysterious and prolonged\r
+absences that gave rise to such strange conjecture among those who were\r
+his friends, or thought that they were so, he himself would creep\r
+upstairs to the locked room, open the door with the key that never left\r
+him now, and stand, with a mirror, in front of the portrait that Basil\r
+Hallward had painted of him, looking now at the evil and aging face on\r
+the canvas, and now at the fair young face that laughed back at him\r
+from the polished glass. The very sharpness of the contrast used to\r
+quicken his sense of pleasure. He grew more and more enamoured of his\r
+own beauty, more and more interested in the corruption of his own soul.\r
+He would examine with minute care, and sometimes with a monstrous and\r
+terrible delight, the hideous lines that seared the wrinkling forehead\r
+or crawled around the heavy sensual mouth, wondering sometimes which\r
+were the more horrible, the signs of sin or the signs of age. He would\r
+place his white hands beside the coarse bloated hands of the picture,\r
+and smile. He mocked the misshapen body and the failing limbs.\r
+\r
+There were moments, indeed, at night, when, lying sleepless in his own\r
+delicately scented chamber, or in the sordid room of the little\r
+ill-famed tavern near the docks which, under an assumed name and in\r
+disguise, it was his habit to frequent, he would think of the ruin he\r
+had brought upon his soul with a pity that was all the more poignant\r
+because it was purely selfish. But moments such as these were rare.\r
+That curiosity about life which Lord Henry had first stirred in him, as\r
+they sat together in the garden of their friend, seemed to increase\r
+with gratification. The more he knew, the more he desired to know. He\r
+had mad hungers that grew more ravenous as he fed them.\r
+\r
+Yet he was not really reckless, at any rate in his relations to\r
+society. Once or twice every month during the winter, and on each\r
+Wednesday evening while the season lasted, he would throw open to the\r
+world his beautiful house and have the most celebrated musicians of the\r
+day to charm his guests with the wonders of their art. His little\r
+dinners, in the settling of which Lord Henry always assisted him, were\r
+noted as much for the careful selection and placing of those invited,\r
+as for the exquisite taste shown in the decoration of the table, with\r
+its subtle symphonic arrangements of exotic flowers, and embroidered\r
+cloths, and antique plate of gold and silver. Indeed, there were many,\r
+especially among the very young men, who saw, or fancied that they saw,\r
+in Dorian Gray the true realization of a type of which they had often\r
+dreamed in Eton or Oxford days, a type that was to combine something of\r
+the real culture of the scholar with all the grace and distinction and\r
+perfect manner of a citizen of the world. To them he seemed to be of\r
+the company of those whom Dante describes as having sought to "make\r
+themselves perfect by the worship of beauty." Like Gautier, he was one\r
+for whom "the visible world existed."\r
+\r
+And, certainly, to him life itself was the first, the greatest, of the\r
+arts, and for it all the other arts seemed to be but a preparation.\r
+Fashion, by which what is really fantastic becomes for a moment\r
+universal, and dandyism, which, in its own way, is an attempt to assert\r
+the absolute modernity of beauty, had, of course, their fascination for\r
+him. His mode of dressing, and the particular styles that from time to\r
+time he affected, had their marked influence on the young exquisites of\r
+the Mayfair balls and Pall Mall club windows, who copied him in\r
+everything that he did, and tried to reproduce the accidental charm of\r
+his graceful, though to him only half-serious, fopperies.\r
+\r
+For, while he was but too ready to accept the position that was almost\r
+immediately offered to him on his coming of age, and found, indeed, a\r
+subtle pleasure in the thought that he might really become to the\r
+London of his own day what to imperial Neronian Rome the author of the\r
+Satyricon once had been, yet in his inmost heart he desired to be\r
+something more than a mere _arbiter elegantiarum_, to be consulted on the\r
+wearing of a jewel, or the knotting of a necktie, or the conduct of a\r
+cane. He sought to elaborate some new scheme of life that would have\r
+its reasoned philosophy and its ordered principles, and find in the\r
+spiritualizing of the senses its highest realization.\r
+\r
+The worship of the senses has often, and with much justice, been\r
+decried, men feeling a natural instinct of terror about passions and\r
+sensations that seem stronger than themselves, and that they are\r
+conscious of sharing with the less highly organized forms of existence.\r
+But it appeared to Dorian Gray that the true nature of the senses had\r
+never been understood, and that they had remained savage and animal\r
+merely because the world had sought to starve them into submission or\r
+to kill them by pain, instead of aiming at making them elements of a\r
+new spirituality, of which a fine instinct for beauty was to be the\r
+dominant characteristic. As he looked back upon man moving through\r
+history, he was haunted by a feeling of loss. So much had been\r
+surrendered! and to such little purpose! There had been mad wilful\r
+rejections, monstrous forms of self-torture and self-denial, whose\r
+origin was fear and whose result was a degradation infinitely more\r
+terrible than that fancied degradation from which, in their ignorance,\r
+they had sought to escape; Nature, in her wonderful irony, driving out\r
+the anchorite to feed with the wild animals of the desert and giving to\r
+the hermit the beasts of the field as his companions.\r
+\r
+Yes: there was to be, as Lord Henry had prophesied, a new Hedonism\r
+that was to recreate life and to save it from that harsh uncomely\r
+puritanism that is having, in our own day, its curious revival. It was\r
+to have its service of the intellect, certainly, yet it was never to\r
+accept any theory or system that would involve the sacrifice of any\r
+mode of passionate experience. Its aim, indeed, was to be experience\r
+itself, and not the fruits of experience, sweet or bitter as they might\r
+be. Of the asceticism that deadens the senses, as of the vulgar\r
+profligacy that dulls them, it was to know nothing. But it was to\r
+teach man to concentrate himself upon the moments of a life that is\r
+itself but a moment.\r
+\r
+There are few of us who have not sometimes wakened before dawn, either\r
+after one of those dreamless nights that make us almost enamoured of\r
+death, or one of those nights of horror and misshapen joy, when through\r
+the chambers of the brain sweep phantoms more terrible than reality\r
+itself, and instinct with that vivid life that lurks in all grotesques,\r
+and that lends to Gothic art its enduring vitality, this art being, one\r
+might fancy, especially the art of those whose minds have been troubled\r
+with the malady of reverie. Gradually white fingers creep through the\r
+curtains, and they appear to tremble. In black fantastic shapes, dumb\r
+shadows crawl into the corners of the room and crouch there. Outside,\r
+there is the stirring of birds among the leaves, or the sound of men\r
+going forth to their work, or the sigh and sob of the wind coming down\r
+from the hills and wandering round the silent house, as though it\r
+feared to wake the sleepers and yet must needs call forth sleep from\r
+her purple cave. Veil after veil of thin dusky gauze is lifted, and by\r
+degrees the forms and colours of things are restored to them, and we\r
+watch the dawn remaking the world in its antique pattern. The wan\r
+mirrors get back their mimic life. The flameless tapers stand where we\r
+had left them, and beside them lies the half-cut book that we had been\r
+studying, or the wired flower that we had worn at the ball, or the\r
+letter that we had been afraid to read, or that we had read too often.\r
+Nothing seems to us changed. Out of the unreal shadows of the night\r
+comes back the real life that we had known. We have to resume it where\r
+we had left off, and there steals over us a terrible sense of the\r
+necessity for the continuance of energy in the same wearisome round of\r
+stereotyped habits, or a wild longing, it may be, that our eyelids\r
+might open some morning upon a world that had been refashioned anew in\r
+the darkness for our pleasure, a world in which things would have fresh\r
+shapes and colours, and be changed, or have other secrets, a world in\r
+which the past would have little or no place, or survive, at any rate,\r
+in no conscious form of obligation or regret, the remembrance even of\r
+joy having its bitterness and the memories of pleasure their pain.\r
+\r
+It was the creation of such worlds as these that seemed to Dorian Gray\r
+to be the true object, or amongst the true objects, of life; and in his\r
+search for sensations that would be at once new and delightful, and\r
+possess that element of strangeness that is so essential to romance, he\r
+would often adopt certain modes of thought that he knew to be really\r
+alien to his nature, abandon himself to their subtle influences, and\r
+then, having, as it were, caught their colour and satisfied his\r
+intellectual curiosity, leave them with that curious indifference that\r
+is not incompatible with a real ardour of temperament, and that,\r
+indeed, according to certain modern psychologists, is often a condition\r
+of it.\r
+\r
+It was rumoured of him once that he was about to join the Roman\r
+Catholic communion, and certainly the Roman ritual had always a great\r
+attraction for him. The daily sacrifice, more awful really than all\r
+the sacrifices of the antique world, stirred him as much by its superb\r
+rejection of the evidence of the senses as by the primitive simplicity\r
+of its elements and the eternal pathos of the human tragedy that it\r
+sought to symbolize. He loved to kneel down on the cold marble\r
+pavement and watch the priest, in his stiff flowered dalmatic, slowly\r
+and with white hands moving aside the veil of the tabernacle, or\r
+raising aloft the jewelled, lantern-shaped monstrance with that pallid\r
+wafer that at times, one would fain think, is indeed the "_panis\r
+caelestis_," the bread of angels, or, robed in the garments of the\r
+Passion of Christ, breaking the Host into the chalice and smiting his\r
+breast for his sins. The fuming censers that the grave boys, in their\r
+lace and scarlet, tossed into the air like great gilt flowers had their\r
+subtle fascination for him. As he passed out, he used to look with\r
+wonder at the black confessionals and long to sit in the dim shadow of\r
+one of them and listen to men and women whispering through the worn\r
+grating the true story of their lives.\r
+\r
+But he never fell into the error of arresting his intellectual\r
+development by any formal acceptance of creed or system, or of\r
+mistaking, for a house in which to live, an inn that is but suitable\r
+for the sojourn of a night, or for a few hours of a night in which\r
+there are no stars and the moon is in travail. Mysticism, with its\r
+marvellous power of making common things strange to us, and the subtle\r
+antinomianism that always seems to accompany it, moved him for a\r
+season; and for a season he inclined to the materialistic doctrines of\r
+the _Darwinismus_ movement in Germany, and found a curious pleasure in\r
+tracing the thoughts and passions of men to some pearly cell in the\r
+brain, or some white nerve in the body, delighting in the conception of\r
+the absolute dependence of the spirit on certain physical conditions,\r
+morbid or healthy, normal or diseased. Yet, as has been said of him\r
+before, no theory of life seemed to him to be of any importance\r
+compared with life itself. He felt keenly conscious of how barren all\r
+intellectual speculation is when separated from action and experiment.\r
+He knew that the senses, no less than the soul, have their spiritual\r
+mysteries to reveal.\r
+\r
+And so he would now study perfumes and the secrets of their\r
+manufacture, distilling heavily scented oils and burning odorous gums\r
+from the East. He saw that there was no mood of the mind that had not\r
+its counterpart in the sensuous life, and set himself to discover their\r
+true relations, wondering what there was in frankincense that made one\r
+mystical, and in ambergris that stirred one's passions, and in violets\r
+that woke the memory of dead romances, and in musk that troubled the\r
+brain, and in champak that stained the imagination; and seeking often\r
+to elaborate a real psychology of perfumes, and to estimate the several\r
+influences of sweet-smelling roots and scented, pollen-laden flowers;\r
+of aromatic balms and of dark and fragrant woods; of spikenard, that\r
+sickens; of hovenia, that makes men mad; and of aloes, that are said to\r
+be able to expel melancholy from the soul.\r
+\r
+At another time he devoted himself entirely to music, and in a long\r
+latticed room, with a vermilion-and-gold ceiling and walls of\r
+olive-green lacquer, he used to give curious concerts in which mad\r
+gipsies tore wild music from little zithers, or grave, yellow-shawled\r
+Tunisians plucked at the strained strings of monstrous lutes, while\r
+grinning Negroes beat monotonously upon copper drums and, crouching\r
+upon scarlet mats, slim turbaned Indians blew through long pipes of\r
+reed or brass and charmed--or feigned to charm--great hooded snakes and\r
+horrible horned adders. The harsh intervals and shrill discords of\r
+barbaric music stirred him at times when Schubert's grace, and Chopin's\r
+beautiful sorrows, and the mighty harmonies of Beethoven himself, fell\r
+unheeded on his ear. He collected together from all parts of the world\r
+the strangest instruments that could be found, either in the tombs of\r
+dead nations or among the few savage tribes that have survived contact\r
+with Western civilizations, and loved to touch and try them. He had\r
+the mysterious _juruparis_ of the Rio Negro Indians, that women are not\r
+allowed to look at and that even youths may not see till they have been\r
+subjected to fasting and scourging, and the earthen jars of the\r
+Peruvians that have the shrill cries of birds, and flutes of human\r
+bones such as Alfonso de Ovalle heard in Chile, and the sonorous green\r
+jaspers that are found near Cuzco and give forth a note of singular\r
+sweetness. He had painted gourds filled with pebbles that rattled when\r
+they were shaken; the long _clarin_ of the Mexicans, into which the\r
+performer does not blow, but through which he inhales the air; the\r
+harsh _ture_ of the Amazon tribes, that is sounded by the sentinels who\r
+sit all day long in high trees, and can be heard, it is said, at a\r
+distance of three leagues; the _teponaztli_, that has two vibrating\r
+tongues of wood and is beaten with sticks that are smeared with an\r
+elastic gum obtained from the milky juice of plants; the _yotl_-bells of\r
+the Aztecs, that are hung in clusters like grapes; and a huge\r
+cylindrical drum, covered with the skins of great serpents, like the\r
+one that Bernal Diaz saw when he went with Cortes into the Mexican\r
+temple, and of whose doleful sound he has left us so vivid a\r
+description. The fantastic character of these instruments fascinated\r
+him, and he felt a curious delight in the thought that art, like\r
+Nature, has her monsters, things of bestial shape and with hideous\r
+voices. Yet, after some time, he wearied of them, and would sit in his\r
+box at the opera, either alone or with Lord Henry, listening in rapt\r
+pleasure to "Tannhauser" and seeing in the prelude to that great work\r
+of art a presentation of the tragedy of his own soul.\r
+\r
+On one occasion he took up the study of jewels, and appeared at a\r
+costume ball as Anne de Joyeuse, Admiral of France, in a dress covered\r
+with five hundred and sixty pearls. This taste enthralled him for\r
+years, and, indeed, may be said never to have left him. He would often\r
+spend a whole day settling and resettling in their cases the various\r
+stones that he had collected, such as the olive-green chrysoberyl that\r
+turns red by lamplight, the cymophane with its wirelike line of silver,\r
+the pistachio-coloured peridot, rose-pink and wine-yellow topazes,\r
+carbuncles of fiery scarlet with tremulous, four-rayed stars, flame-red\r
+cinnamon-stones, orange and violet spinels, and amethysts with their\r
+alternate layers of ruby and sapphire. He loved the red gold of the\r
+sunstone, and the moonstone's pearly whiteness, and the broken rainbow\r
+of the milky opal. He procured from Amsterdam three emeralds of\r
+extraordinary size and richness of colour, and had a turquoise _de la\r
+vieille roche_ that was the envy of all the connoisseurs.\r
+\r
+He discovered wonderful stories, also, about jewels. In Alphonso's\r
+Clericalis Disciplina a serpent was mentioned with eyes of real\r
+jacinth, and in the romantic history of Alexander, the Conqueror of\r
+Emathia was said to have found in the vale of Jordan snakes "with\r
+collars of real emeralds growing on their backs." There was a gem in\r
+the brain of the dragon, Philostratus told us, and "by the exhibition\r
+of golden letters and a scarlet robe" the monster could be thrown into\r
+a magical sleep and slain. According to the great alchemist, Pierre de\r
+Boniface, the diamond rendered a man invisible, and the agate of India\r
+made him eloquent. The cornelian appeased anger, and the hyacinth\r
+provoked sleep, and the amethyst drove away the fumes of wine. The\r
+garnet cast out demons, and the hydropicus deprived the moon of her\r
+colour. The selenite waxed and waned with the moon, and the meloceus,\r
+that discovers thieves, could be affected only by the blood of kids.\r
+Leonardus Camillus had seen a white stone taken from the brain of a\r
+newly killed toad, that was a certain antidote against poison. The\r
+bezoar, that was found in the heart of the Arabian deer, was a charm\r
+that could cure the plague. In the nests of Arabian birds was the\r
+aspilates, that, according to Democritus, kept the wearer from any\r
+danger by fire.\r
+\r
+The King of Ceilan rode through his city with a large ruby in his hand,\r
+as the ceremony of his coronation. The gates of the palace of John the\r
+Priest were "made of sardius, with the horn of the horned snake\r
+inwrought, so that no man might bring poison within." Over the gable\r
+were "two golden apples, in which were two carbuncles," so that the\r
+gold might shine by day and the carbuncles by night. In Lodge's\r
+strange romance 'A Margarite of America', it was stated that in the\r
+chamber of the queen one could behold "all the chaste ladies of the\r
+world, inchased out of silver, looking through fair mirrours of\r
+chrysolites, carbuncles, sapphires, and greene emeraults." Marco Polo\r
+had seen the inhabitants of Zipangu place rose-coloured pearls in the\r
+mouths of the dead. A sea-monster had been enamoured of the pearl that\r
+the diver brought to King Perozes, and had slain the thief, and mourned\r
+for seven moons over its loss. When the Huns lured the king into the\r
+great pit, he flung it away--Procopius tells the story--nor was it ever\r
+found again, though the Emperor Anastasius offered five hundred-weight\r
+of gold pieces for it. The King of Malabar had shown to a certain\r
+Venetian a rosary of three hundred and four pearls, one for every god\r
+that he worshipped.\r
+\r
+When the Duke de Valentinois, son of Alexander VI, visited Louis XII of\r
+France, his horse was loaded with gold leaves, according to Brantome,\r
+and his cap had double rows of rubies that threw out a great light.\r
+Charles of England had ridden in stirrups hung with four hundred and\r
+twenty-one diamonds. Richard II had a coat, valued at thirty thousand\r
+marks, which was covered with balas rubies. Hall described Henry VIII,\r
+on his way to the Tower previous to his coronation, as wearing "a\r
+jacket of raised gold, the placard embroidered with diamonds and other\r
+rich stones, and a great bauderike about his neck of large balasses."\r
+The favourites of James I wore ear-rings of emeralds set in gold\r
+filigrane. Edward II gave to Piers Gaveston a suit of red-gold armour\r
+studded with jacinths, a collar of gold roses set with\r
+turquoise-stones, and a skull-cap _parseme_ with pearls. Henry II wore\r
+jewelled gloves reaching to the elbow, and had a hawk-glove sewn with\r
+twelve rubies and fifty-two great orients. The ducal hat of Charles\r
+the Rash, the last Duke of Burgundy of his race, was hung with\r
+pear-shaped pearls and studded with sapphires.\r
+\r
+How exquisite life had once been! How gorgeous in its pomp and\r
+decoration! Even to read of the luxury of the dead was wonderful.\r
+\r
+Then he turned his attention to embroideries and to the tapestries that\r
+performed the office of frescoes in the chill rooms of the northern\r
+nations of Europe. As he investigated the subject--and he always had\r
+an extraordinary faculty of becoming absolutely absorbed for the moment\r
+in whatever he took up--he was almost saddened by the reflection of the\r
+ruin that time brought on beautiful and wonderful things. He, at any\r
+rate, had escaped that. Summer followed summer, and the yellow\r
+jonquils bloomed and died many times, and nights of horror repeated the\r
+story of their shame, but he was unchanged. No winter marred his face\r
+or stained his flowerlike bloom. How different it was with material\r
+things! Where had they passed to? Where was the great crocus-coloured\r
+robe, on which the gods fought against the giants, that had been worked\r
+by brown girls for the pleasure of Athena? Where the huge velarium\r
+that Nero had stretched across the Colosseum at Rome, that Titan sail\r
+of purple on which was represented the starry sky, and Apollo driving a\r
+chariot drawn by white, gilt-reined steeds? He longed to see the\r
+curious table-napkins wrought for the Priest of the Sun, on which were\r
+displayed all the dainties and viands that could be wanted for a feast;\r
+the mortuary cloth of King Chilperic, with its three hundred golden\r
+bees; the fantastic robes that excited the indignation of the Bishop of\r
+Pontus and were figured with "lions, panthers, bears, dogs, forests,\r
+rocks, hunters--all, in fact, that a painter can copy from nature"; and\r
+the coat that Charles of Orleans once wore, on the sleeves of which\r
+were embroidered the verses of a song beginning "_Madame, je suis tout\r
+joyeux_," the musical accompaniment of the words being wrought in gold\r
+thread, and each note, of square shape in those days, formed with four\r
+pearls. He read of the room that was prepared at the palace at Rheims\r
+for the use of Queen Joan of Burgundy and was decorated with "thirteen\r
+hundred and twenty-one parrots, made in broidery, and blazoned with the\r
+king's arms, and five hundred and sixty-one butterflies, whose wings\r
+were similarly ornamented with the arms of the queen, the whole worked\r
+in gold." Catherine de Medicis had a mourning-bed made for her of\r
+black velvet powdered with crescents and suns. Its curtains were of\r
+damask, with leafy wreaths and garlands, figured upon a gold and silver\r
+ground, and fringed along the edges with broideries of pearls, and it\r
+stood in a room hung with rows of the queen's devices in cut black\r
+velvet upon cloth of silver. Louis XIV had gold embroidered caryatides\r
+fifteen feet high in his apartment. The state bed of Sobieski, King of\r
+Poland, was made of Smyrna gold brocade embroidered in turquoises with\r
+verses from the Koran. Its supports were of silver gilt, beautifully\r
+chased, and profusely set with enamelled and jewelled medallions. It\r
+had been taken from the Turkish camp before Vienna, and the standard of\r
+Mohammed had stood beneath the tremulous gilt of its canopy.\r
+\r
+And so, for a whole year, he sought to accumulate the most exquisite\r
+specimens that he could find of textile and embroidered work, getting\r
+the dainty Delhi muslins, finely wrought with gold-thread palmates and\r
+stitched over with iridescent beetles' wings; the Dacca gauzes, that\r
+from their transparency are known in the East as "woven air," and\r
+"running water," and "evening dew"; strange figured cloths from Java;\r
+elaborate yellow Chinese hangings; books bound in tawny satins or fair\r
+blue silks and wrought with _fleurs-de-lis_, birds and images; veils of\r
+_lacis_ worked in Hungary point; Sicilian brocades and stiff Spanish\r
+velvets; Georgian work, with its gilt coins, and Japanese _Foukousas_,\r
+with their green-toned golds and their marvellously plumaged birds.\r
+\r
+He had a special passion, also, for ecclesiastical vestments, as indeed\r
+he had for everything connected with the service of the Church. In the\r
+long cedar chests that lined the west gallery of his house, he had\r
+stored away many rare and beautiful specimens of what is really the\r
+raiment of the Bride of Christ, who must wear purple and jewels and\r
+fine linen that she may hide the pallid macerated body that is worn by\r
+the suffering that she seeks for and wounded by self-inflicted pain.\r
+He possessed a gorgeous cope of crimson silk and gold-thread damask,\r
+figured with a repeating pattern of golden pomegranates set in\r
+six-petalled formal blossoms, beyond which on either side was the\r
+pine-apple device wrought in seed-pearls. The orphreys were divided\r
+into panels representing scenes from the life of the Virgin, and the\r
+coronation of the Virgin was figured in coloured silks upon the hood.\r
+This was Italian work of the fifteenth century. Another cope was of\r
+green velvet, embroidered with heart-shaped groups of acanthus-leaves,\r
+from which spread long-stemmed white blossoms, the details of which\r
+were picked out with silver thread and coloured crystals. The morse\r
+bore a seraph's head in gold-thread raised work. The orphreys were\r
+woven in a diaper of red and gold silk, and were starred with\r
+medallions of many saints and martyrs, among whom was St. Sebastian.\r
+He had chasubles, also, of amber-coloured silk, and blue silk and gold\r
+brocade, and yellow silk damask and cloth of gold, figured with\r
+representations of the Passion and Crucifixion of Christ, and\r
+embroidered with lions and peacocks and other emblems; dalmatics of\r
+white satin and pink silk damask, decorated with tulips and dolphins\r
+and _fleurs-de-lis_; altar frontals of crimson velvet and blue linen; and\r
+many corporals, chalice-veils, and sudaria. In the mystic offices to\r
+which such things were put, there was something that quickened his\r
+imagination.\r
+\r
+For these treasures, and everything that he collected in his lovely\r
+house, were to be to him means of forgetfulness, modes by which he\r
+could escape, for a season, from the fear that seemed to him at times\r
+to be almost too great to be borne. Upon the walls of the lonely\r
+locked room where he had spent so much of his boyhood, he had hung with\r
+his own hands the terrible portrait whose changing features showed him\r
+the real degradation of his life, and in front of it had draped the\r
+purple-and-gold pall as a curtain. For weeks he would not go there,\r
+would forget the hideous painted thing, and get back his light heart,\r
+his wonderful joyousness, his passionate absorption in mere existence.\r
+Then, suddenly, some night he would creep out of the house, go down to\r
+dreadful places near Blue Gate Fields, and stay there, day after day,\r
+until he was driven away. On his return he would sit in front of the\r
+picture, sometimes loathing it and himself, but filled, at other\r
+times, with that pride of individualism that is half the\r
+fascination of sin, and smiling with secret pleasure at the misshapen\r
+shadow that had to bear the burden that should have been his own.\r
+\r
+After a few years he could not endure to be long out of England, and\r
+gave up the villa that he had shared at Trouville with Lord Henry, as\r
+well as the little white walled-in house at Algiers where they had more\r
+than once spent the winter. He hated to be separated from the picture\r
+that was such a part of his life, and was also afraid that during his\r
+absence some one might gain access to the room, in spite of the\r
+elaborate bars that he had caused to be placed upon the door.\r
+\r
+He was quite conscious that this would tell them nothing. It was true\r
+that the portrait still preserved, under all the foulness and ugliness\r
+of the face, its marked likeness to himself; but what could they learn\r
+from that? He would laugh at any one who tried to taunt him. He had\r
+not painted it. What was it to him how vile and full of shame it\r
+looked? Even if he told them, would they believe it?\r
+\r
+Yet he was afraid. Sometimes when he was down at his great house in\r
+Nottinghamshire, entertaining the fashionable young men of his own rank\r
+who were his chief companions, and astounding the county by the wanton\r
+luxury and gorgeous splendour of his mode of life, he would suddenly\r
+leave his guests and rush back to town to see that the door had not\r
+been tampered with and that the picture was still there. What if it\r
+should be stolen? The mere thought made him cold with horror. Surely\r
+the world would know his secret then. Perhaps the world already\r
+suspected it.\r
+\r
+For, while he fascinated many, there were not a few who distrusted him.\r
+He was very nearly blackballed at a West End club of which his birth\r
+and social position fully entitled him to become a member, and it was\r
+said that on one occasion, when he was brought by a friend into the\r
+smoking-room of the Churchill, the Duke of Berwick and another\r
+gentleman got up in a marked manner and went out. Curious stories\r
+became current about him after he had passed his twenty-fifth year. It\r
+was rumoured that he had been seen brawling with foreign sailors in a\r
+low den in the distant parts of Whitechapel, and that he consorted with\r
+thieves and coiners and knew the mysteries of their trade. His\r
+extraordinary absences became notorious, and, when he used to reappear\r
+again in society, men would whisper to each other in corners, or pass\r
+him with a sneer, or look at him with cold searching eyes, as though\r
+they were determined to discover his secret.\r
+\r
+Of such insolences and attempted slights he, of course, took no notice,\r
+and in the opinion of most people his frank debonair manner, his\r
+charming boyish smile, and the infinite grace of that wonderful youth\r
+that seemed never to leave him, were in themselves a sufficient answer\r
+to the calumnies, for so they termed them, that were circulated about\r
+him. It was remarked, however, that some of those who had been most\r
+intimate with him appeared, after a time, to shun him. Women who had\r
+wildly adored him, and for his sake had braved all social censure and\r
+set convention at defiance, were seen to grow pallid with shame or\r
+horror if Dorian Gray entered the room.\r
+\r
+Yet these whispered scandals only increased in the eyes of many his\r
+strange and dangerous charm. His great wealth was a certain element of\r
+security. Society--civilized society, at least--is never very ready to\r
+believe anything to the detriment of those who are both rich and\r
+fascinating. It feels instinctively that manners are of more\r
+importance than morals, and, in its opinion, the highest respectability\r
+is of much less value than the possession of a good _chef_. And, after\r
+all, it is a very poor consolation to be told that the man who has\r
+given one a bad dinner, or poor wine, is irreproachable in his private\r
+life. Even the cardinal virtues cannot atone for half-cold _entrees_, as\r
+Lord Henry remarked once, in a discussion on the subject, and there is\r
+possibly a good deal to be said for his view. For the canons of good\r
+society are, or should be, the same as the canons of art. Form is\r
+absolutely essential to it. It should have the dignity of a ceremony,\r
+as well as its unreality, and should combine the insincere character of\r
+a romantic play with the wit and beauty that make such plays delightful\r
+to us. Is insincerity such a terrible thing? I think not. It is\r
+merely a method by which we can multiply our personalities.\r
+\r
+Such, at any rate, was Dorian Gray's opinion. He used to wonder at the\r
+shallow psychology of those who conceive the ego in man as a thing\r
+simple, permanent, reliable, and of one essence. To him, man was a\r
+being with myriad lives and myriad sensations, a complex multiform\r
+creature that bore within itself strange legacies of thought and\r
+passion, and whose very flesh was tainted with the monstrous maladies\r
+of the dead. He loved to stroll through the gaunt cold picture-gallery\r
+of his country house and look at the various portraits of those whose\r
+blood flowed in his veins. Here was Philip Herbert, described by\r
+Francis Osborne, in his Memoires on the Reigns of Queen Elizabeth and\r
+King James, as one who was "caressed by the Court for his handsome\r
+face, which kept him not long company." Was it young Herbert's life\r
+that he sometimes led? Had some strange poisonous germ crept from body\r
+to body till it had reached his own? Was it some dim sense of that\r
+ruined grace that had made him so suddenly, and almost without cause,\r
+give utterance, in Basil Hallward's studio, to the mad prayer that had\r
+so changed his life? Here, in gold-embroidered red doublet, jewelled\r
+surcoat, and gilt-edged ruff and wristbands, stood Sir Anthony Sherard,\r
+with his silver-and-black armour piled at his feet. What had this\r
+man's legacy been? Had the lover of Giovanna of Naples bequeathed him\r
+some inheritance of sin and shame? Were his own actions merely the\r
+dreams that the dead man had not dared to realize? Here, from the\r
+fading canvas, smiled Lady Elizabeth Devereux, in her gauze hood, pearl\r
+stomacher, and pink slashed sleeves. A flower was in her right hand,\r
+and her left clasped an enamelled collar of white and damask roses. On\r
+a table by her side lay a mandolin and an apple. There were large\r
+green rosettes upon her little pointed shoes. He knew her life, and\r
+the strange stories that were told about her lovers. Had he something\r
+of her temperament in him? These oval, heavy-lidded eyes seemed to\r
+look curiously at him. What of George Willoughby, with his powdered\r
+hair and fantastic patches? How evil he looked! The face was\r
+saturnine and swarthy, and the sensual lips seemed to be twisted with\r
+disdain. Delicate lace ruffles fell over the lean yellow hands that\r
+were so overladen with rings. He had been a macaroni of the eighteenth\r
+century, and the friend, in his youth, of Lord Ferrars. What of the\r
+second Lord Beckenham, the companion of the Prince Regent in his\r
+wildest days, and one of the witnesses at the secret marriage with Mrs.\r
+Fitzherbert? How proud and handsome he was, with his chestnut curls\r
+and insolent pose! What passions had he bequeathed? The world had\r
+looked upon him as infamous. He had led the orgies at Carlton House.\r
+The star of the Garter glittered upon his breast. Beside him hung the\r
+portrait of his wife, a pallid, thin-lipped woman in black. Her blood,\r
+also, stirred within him. How curious it all seemed! And his mother\r
+with her Lady Hamilton face and her moist, wine-dashed lips--he knew\r
+what he had got from her. He had got from her his beauty, and his\r
+passion for the beauty of others. She laughed at him in her loose\r
+Bacchante dress. There were vine leaves in her hair. The purple\r
+spilled from the cup she was holding. The carnations of the painting\r
+had withered, but the eyes were still wonderful in their depth and\r
+brilliancy of colour. They seemed to follow him wherever he went.\r
+\r
+Yet one had ancestors in literature as well as in one's own race,\r
+nearer perhaps in type and temperament, many of them, and certainly\r
+with an influence of which one was more absolutely conscious. There\r
+were times when it appeared to Dorian Gray that the whole of history\r
+was merely the record of his own life, not as he had lived it in act\r
+and circumstance, but as his imagination had created it for him, as it\r
+had been in his brain and in his passions. He felt that he had known\r
+them all, those strange terrible figures that had passed across the\r
+stage of the world and made sin so marvellous and evil so full of\r
+subtlety. It seemed to him that in some mysterious way their lives had\r
+been his own.\r
+\r
+The hero of the wonderful novel that had so influenced his life had\r
+himself known this curious fancy. In the seventh chapter he tells how,\r
+crowned with laurel, lest lightning might strike him, he had sat, as\r
+Tiberius, in a garden at Capri, reading the shameful books of\r
+Elephantis, while dwarfs and peacocks strutted round him and the\r
+flute-player mocked the swinger of the censer; and, as Caligula, had\r
+caroused with the green-shirted jockeys in their stables and supped in\r
+an ivory manger with a jewel-frontleted horse; and, as Domitian, had\r
+wandered through a corridor lined with marble mirrors, looking round\r
+with haggard eyes for the reflection of the dagger that was to end his\r
+days, and sick with that ennui, that terrible _taedium vitae_, that comes\r
+on those to whom life denies nothing; and had peered through a clear\r
+emerald at the red shambles of the circus and then, in a litter of\r
+pearl and purple drawn by silver-shod mules, been carried through the\r
+Street of Pomegranates to a House of Gold and heard men cry on Nero\r
+Caesar as he passed by; and, as Elagabalus, had painted his face with\r
+colours, and plied the distaff among the women, and brought the Moon\r
+from Carthage and given her in mystic marriage to the Sun.\r
+\r
+Over and over again Dorian used to read this fantastic chapter, and the\r
+two chapters immediately following, in which, as in some curious\r
+tapestries or cunningly wrought enamels, were pictured the awful and\r
+beautiful forms of those whom vice and blood and weariness had made\r
+monstrous or mad: Filippo, Duke of Milan, who slew his wife and\r
+painted her lips with a scarlet poison that her lover might suck death\r
+from the dead thing he fondled; Pietro Barbi, the Venetian, known as\r
+Paul the Second, who sought in his vanity to assume the title of\r
+Formosus, and whose tiara, valued at two hundred thousand florins, was\r
+bought at the price of a terrible sin; Gian Maria Visconti, who used\r
+hounds to chase living men and whose murdered body was covered with\r
+roses by a harlot who had loved him; the Borgia on his white horse,\r
+with Fratricide riding beside him and his mantle stained with the blood\r
+of Perotto; Pietro Riario, the young Cardinal Archbishop of Florence,\r
+child and minion of Sixtus IV, whose beauty was equalled only by his\r
+debauchery, and who received Leonora of Aragon in a pavilion of white\r
+and crimson silk, filled with nymphs and centaurs, and gilded a boy\r
+that he might serve at the feast as Ganymede or Hylas; Ezzelin, whose\r
+melancholy could be cured only by the spectacle of death, and who had a\r
+passion for red blood, as other men have for red wine--the son of the\r
+Fiend, as was reported, and one who had cheated his father at dice when\r
+gambling with him for his own soul; Giambattista Cibo, who in mockery\r
+took the name of Innocent and into whose torpid veins the blood of\r
+three lads was infused by a Jewish doctor; Sigismondo Malatesta, the\r
+lover of Isotta and the lord of Rimini, whose effigy was burned at Rome\r
+as the enemy of God and man, who strangled Polyssena with a napkin, and\r
+gave poison to Ginevra d'Este in a cup of emerald, and in honour of a\r
+shameful passion built a pagan church for Christian worship; Charles\r
+VI, who had so wildly adored his brother's wife that a leper had warned\r
+him of the insanity that was coming on him, and who, when his brain had\r
+sickened and grown strange, could only be soothed by Saracen cards\r
+painted with the images of love and death and madness; and, in his\r
+trimmed jerkin and jewelled cap and acanthuslike curls, Grifonetto\r
+Baglioni, who slew Astorre with his bride, and Simonetto with his page,\r
+and whose comeliness was such that, as he lay dying in the yellow\r
+piazza of Perugia, those who had hated him could not choose but weep,\r
+and Atalanta, who had cursed him, blessed him.\r
+\r
+There was a horrible fascination in them all. He saw them at night,\r
+and they troubled his imagination in the day. The Renaissance knew of\r
+strange manners of poisoning--poisoning by a helmet and a lighted\r
+torch, by an embroidered glove and a jewelled fan, by a gilded pomander\r
+and by an amber chain. Dorian Gray had been poisoned by a book. There\r
+were moments when he looked on evil simply as a mode through which he\r
+could realize his conception of the beautiful.\r
+\r
+\r
+\r
+CHAPTER 12\r
+\r
+It was on the ninth of November, the eve of his own thirty-eighth\r
+birthday, as he often remembered afterwards.\r
+\r
+He was walking home about eleven o'clock from Lord Henry's, where he\r
+had been dining, and was wrapped in heavy furs, as the night was cold\r
+and foggy. At the corner of Grosvenor Square and South Audley Street,\r
+a man passed him in the mist, walking very fast and with the collar of\r
+his grey ulster turned up. He had a bag in his hand. Dorian\r
+recognized him. It was Basil Hallward. A strange sense of fear, for\r
+which he could not account, came over him. He made no sign of\r
+recognition and went on quickly in the direction of his own house.\r
+\r
+But Hallward had seen him. Dorian heard him first stopping on the\r
+pavement and then hurrying after him. In a few moments, his hand was\r
+on his arm.\r
+\r
+"Dorian! What an extraordinary piece of luck! I have been waiting for\r
+you in your library ever since nine o'clock. Finally I took pity on\r
+your tired servant and told him to go to bed, as he let me out. I am\r
+off to Paris by the midnight train, and I particularly wanted to see\r
+you before I left. I thought it was you, or rather your fur coat, as\r
+you passed me. But I wasn't quite sure. Didn't you recognize me?"\r
+\r
+"In this fog, my dear Basil? Why, I can't even recognize Grosvenor\r
+Square. I believe my house is somewhere about here, but I don't feel\r
+at all certain about it. I am sorry you are going away, as I have not\r
+seen you for ages. But I suppose you will be back soon?"\r
+\r
+"No: I am going to be out of England for six months. I intend to take\r
+a studio in Paris and shut myself up till I have finished a great\r
+picture I have in my head. However, it wasn't about myself I wanted to\r
+talk. Here we are at your door. Let me come in for a moment. I have\r
+something to say to you."\r
+\r
+"I shall be charmed. But won't you miss your train?" said Dorian Gray\r
+languidly as he passed up the steps and opened the door with his\r
+latch-key.\r
+\r
+The lamplight struggled out through the fog, and Hallward looked at his\r
+watch. "I have heaps of time," he answered. "The train doesn't go\r
+till twelve-fifteen, and it is only just eleven. In fact, I was on my\r
+way to the club to look for you, when I met you. You see, I shan't\r
+have any delay about luggage, as I have sent on my heavy things. All I\r
+have with me is in this bag, and I can easily get to Victoria in twenty\r
+minutes."\r
+\r
+Dorian looked at him and smiled. "What a way for a fashionable painter\r
+to travel! A Gladstone bag and an ulster! Come in, or the fog will\r
+get into the house. And mind you don't talk about anything serious.\r
+Nothing is serious nowadays. At least nothing should be."\r
+\r
+Hallward shook his head, as he entered, and followed Dorian into the\r
+library. There was a bright wood fire blazing in the large open\r
+hearth. The lamps were lit, and an open Dutch silver spirit-case\r
+stood, with some siphons of soda-water and large cut-glass tumblers, on\r
+a little marqueterie table.\r
+\r
+"You see your servant made me quite at home, Dorian. He gave me\r
+everything I wanted, including your best gold-tipped cigarettes. He is\r
+a most hospitable creature. I like him much better than the Frenchman\r
+you used to have. What has become of the Frenchman, by the bye?"\r
+\r
+Dorian shrugged his shoulders. "I believe he married Lady Radley's\r
+maid, and has established her in Paris as an English dressmaker.\r
+Anglomania is very fashionable over there now, I hear. It seems silly\r
+of the French, doesn't it? But--do you know?--he was not at all a bad\r
+servant. I never liked him, but I had nothing to complain about. One\r
+often imagines things that are quite absurd. He was really very\r
+devoted to me and seemed quite sorry when he went away. Have another\r
+brandy-and-soda? Or would you like hock-and-seltzer? I always take\r
+hock-and-seltzer myself. There is sure to be some in the next room."\r
+\r
+"Thanks, I won't have anything more," said the painter, taking his cap\r
+and coat off and throwing them on the bag that he had placed in the\r
+corner. "And now, my dear fellow, I want to speak to you seriously.\r
+Don't frown like that. You make it so much more difficult for me."\r
+\r
+"What is it all about?" cried Dorian in his petulant way, flinging\r
+himself down on the sofa. "I hope it is not about myself. I am tired\r
+of myself to-night. I should like to be somebody else."\r
+\r
+"It is about yourself," answered Hallward in his grave deep voice, "and\r
+I must say it to you. I shall only keep you half an hour."\r
+\r
+Dorian sighed and lit a cigarette. "Half an hour!" he murmured.\r
+\r
+"It is not much to ask of you, Dorian, and it is entirely for your own\r
+sake that I am speaking. I think it right that you should know that\r
+the most dreadful things are being said against you in London."\r
+\r
+"I don't wish to know anything about them. I love scandals about other\r
+people, but scandals about myself don't interest me. They have not got\r
+the charm of novelty."\r
+\r
+"They must interest you, Dorian. Every gentleman is interested in his\r
+good name. You don't want people to talk of you as something vile and\r
+degraded. Of course, you have your position, and your wealth, and all\r
+that kind of thing. But position and wealth are not everything. Mind\r
+you, I don't believe these rumours at all. At least, I can't believe\r
+them when I see you. Sin is a thing that writes itself across a man's\r
+face. It cannot be concealed. People talk sometimes of secret vices.\r
+There are no such things. If a wretched man has a vice, it shows\r
+itself in the lines of his mouth, the droop of his eyelids, the\r
+moulding of his hands even. Somebody--I won't mention his name, but\r
+you know him--came to me last year to have his portrait done. I had\r
+never seen him before, and had never heard anything about him at the\r
+time, though I have heard a good deal since. He offered an extravagant\r
+price. I refused him. There was something in the shape of his fingers\r
+that I hated. I know now that I was quite right in what I fancied\r
+about him. His life is dreadful. But you, Dorian, with your pure,\r
+bright, innocent face, and your marvellous untroubled youth--I can't\r
+believe anything against you. And yet I see you very seldom, and you\r
+never come down to the studio now, and when I am away from you, and I\r
+hear all these hideous things that people are whispering about you, I\r
+don't know what to say. Why is it, Dorian, that a man like the Duke of\r
+Berwick leaves the room of a club when you enter it? Why is it that so\r
+many gentlemen in London will neither go to your house or invite you to\r
+theirs? You used to be a friend of Lord Staveley. I met him at dinner\r
+last week. Your name happened to come up in conversation, in\r
+connection with the miniatures you have lent to the exhibition at the\r
+Dudley. Staveley curled his lip and said that you might have the most\r
+artistic tastes, but that you were a man whom no pure-minded girl\r
+should be allowed to know, and whom no chaste woman should sit in the\r
+same room with. I reminded him that I was a friend of yours, and asked\r
+him what he meant. He told me. He told me right out before everybody.\r
+It was horrible! Why is your friendship so fatal to young men? There\r
+was that wretched boy in the Guards who committed suicide. You were\r
+his great friend. There was Sir Henry Ashton, who had to leave England\r
+with a tarnished name. You and he were inseparable. What about Adrian\r
+Singleton and his dreadful end? What about Lord Kent's only son and\r
+his career? I met his father yesterday in St. James's Street. He\r
+seemed broken with shame and sorrow. What about the young Duke of\r
+Perth? What sort of life has he got now? What gentleman would\r
+associate with him?"\r
+\r
+"Stop, Basil. You are talking about things of which you know nothing,"\r
+said Dorian Gray, biting his lip, and with a note of infinite contempt\r
+in his voice. "You ask me why Berwick leaves a room when I enter it.\r
+It is because I know everything about his life, not because he knows\r
+anything about mine. With such blood as he has in his veins, how could\r
+his record be clean? You ask me about Henry Ashton and young Perth.\r
+Did I teach the one his vices, and the other his debauchery? If Kent's\r
+silly son takes his wife from the streets, what is that to me? If\r
+Adrian Singleton writes his friend's name across a bill, am I his\r
+keeper? I know how people chatter in England. The middle classes air\r
+their moral prejudices over their gross dinner-tables, and whisper\r
+about what they call the profligacies of their betters in order to try\r
+and pretend that they are in smart society and on intimate terms with\r
+the people they slander. In this country, it is enough for a man to\r
+have distinction and brains for every common tongue to wag against him.\r
+And what sort of lives do these people, who pose as being moral, lead\r
+themselves? My dear fellow, you forget that we are in the native land\r
+of the hypocrite."\r
+\r
+"Dorian," cried Hallward, "that is not the question. England is bad\r
+enough I know, and English society is all wrong. That is the reason\r
+why I want you to be fine. You have not been fine. One has a right to\r
+judge of a man by the effect he has over his friends. Yours seem to\r
+lose all sense of honour, of goodness, of purity. You have filled them\r
+with a madness for pleasure. They have gone down into the depths. You\r
+led them there. Yes: you led them there, and yet you can smile, as\r
+you are smiling now. And there is worse behind. I know you and Harry\r
+are inseparable. Surely for that reason, if for none other, you should\r
+not have made his sister's name a by-word."\r
+\r
+"Take care, Basil. You go too far."\r
+\r
+"I must speak, and you must listen. You shall listen. When you met\r
+Lady Gwendolen, not a breath of scandal had ever touched her. Is there\r
+a single decent woman in London now who would drive with her in the\r
+park? Why, even her children are not allowed to live with her. Then\r
+there are other stories--stories that you have been seen creeping at\r
+dawn out of dreadful houses and slinking in disguise into the foulest\r
+dens in London. Are they true? Can they be true? When I first heard\r
+them, I laughed. I hear them now, and they make me shudder. What\r
+about your country-house and the life that is led there? Dorian, you\r
+don't know what is said about you. I won't tell you that I don't want\r
+to preach to you. I remember Harry saying once that every man who\r
+turned himself into an amateur curate for the moment always began by\r
+saying that, and then proceeded to break his word. I do want to preach\r
+to you. I want you to lead such a life as will make the world respect\r
+you. I want you to have a clean name and a fair record. I want you to\r
+get rid of the dreadful people you associate with. Don't shrug your\r
+shoulders like that. Don't be so indifferent. You have a wonderful\r
+influence. Let it be for good, not for evil. They say that you\r
+corrupt every one with whom you become intimate, and that it is quite\r
+sufficient for you to enter a house for shame of some kind to follow\r
+after. I don't know whether it is so or not. How should I know? But\r
+it is said of you. I am told things that it seems impossible to doubt.\r
+Lord Gloucester was one of my greatest friends at Oxford. He showed me\r
+a letter that his wife had written to him when she was dying alone in\r
+her villa at Mentone. Your name was implicated in the most terrible\r
+confession I ever read. I told him that it was absurd--that I knew you\r
+thoroughly and that you were incapable of anything of the kind. Know\r
+you? I wonder do I know you? Before I could answer that, I should\r
+have to see your soul."\r
+\r
+"To see my soul!" muttered Dorian Gray, starting up from the sofa and\r
+turning almost white from fear.\r
+\r
+"Yes," answered Hallward gravely, and with deep-toned sorrow in his\r
+voice, "to see your soul. But only God can do that."\r
+\r
+A bitter laugh of mockery broke from the lips of the younger man. "You\r
+shall see it yourself, to-night!" he cried, seizing a lamp from the\r
+table. "Come: it is your own handiwork. Why shouldn't you look at\r
+it? You can tell the world all about it afterwards, if you choose.\r
+Nobody would believe you. If they did believe you, they would like me\r
+all the better for it. I know the age better than you do, though you\r
+will prate about it so tediously. Come, I tell you. You have\r
+chattered enough about corruption. Now you shall look on it face to\r
+face."\r
+\r
+There was the madness of pride in every word he uttered. He stamped\r
+his foot upon the ground in his boyish insolent manner. He felt a\r
+terrible joy at the thought that some one else was to share his secret,\r
+and that the man who had painted the portrait that was the origin of\r
+all his shame was to be burdened for the rest of his life with the\r
+hideous memory of what he had done.\r
+\r
+"Yes," he continued, coming closer to him and looking steadfastly into\r
+his stern eyes, "I shall show you my soul. You shall see the thing\r
+that you fancy only God can see."\r
+\r
+Hallward started back. "This is blasphemy, Dorian!" he cried. "You\r
+must not say things like that. They are horrible, and they don't mean\r
+anything."\r
+\r
+"You think so?" He laughed again.\r
+\r
+"I know so. As for what I said to you to-night, I said it for your\r
+good. You know I have been always a stanch friend to you."\r
+\r
+"Don't touch me. Finish what you have to say."\r
+\r
+A twisted flash of pain shot across the painter's face. He paused for\r
+a moment, and a wild feeling of pity came over him. After all, what\r
+right had he to pry into the life of Dorian Gray? If he had done a\r
+tithe of what was rumoured about him, how much he must have suffered!\r
+Then he straightened himself up, and walked over to the fire-place, and\r
+stood there, looking at the burning logs with their frostlike ashes and\r
+their throbbing cores of flame.\r
+\r
+"I am waiting, Basil," said the young man in a hard clear voice.\r
+\r
+He turned round. "What I have to say is this," he cried. "You must\r
+give me some answer to these horrible charges that are made against\r
+you. If you tell me that they are absolutely untrue from beginning to\r
+end, I shall believe you. Deny them, Dorian, deny them! Can't you see\r
+what I am going through? My God! don't tell me that you are bad, and\r
+corrupt, and shameful."\r
+\r
+Dorian Gray smiled. There was a curl of contempt in his lips. "Come\r
+upstairs, Basil," he said quietly. "I keep a diary of my life from day\r
+to day, and it never leaves the room in which it is written. I shall\r
+show it to you if you come with me."\r
+\r
+"I shall come with you, Dorian, if you wish it. I see I have missed my\r
+train. That makes no matter. I can go to-morrow. But don't ask me to\r
+read anything to-night. All I want is a plain answer to my question."\r
+\r
+"That shall be given to you upstairs. I could not give it here. You\r
+will not have to read long."\r
+\r
+\r
+\r
+CHAPTER 13\r
+\r
+He passed out of the room and began the ascent, Basil Hallward\r
+following close behind. They walked softly, as men do instinctively at\r
+night. The lamp cast fantastic shadows on the wall and staircase. A\r
+rising wind made some of the windows rattle.\r
+\r
+When they reached the top landing, Dorian set the lamp down on the\r
+floor, and taking out the key, turned it in the lock. "You insist on\r
+knowing, Basil?" he asked in a low voice.\r
+\r
+"Yes."\r
+\r
+"I am delighted," he answered, smiling. Then he added, somewhat\r
+harshly, "You are the one man in the world who is entitled to know\r
+everything about me. You have had more to do with my life than you\r
+think"; and, taking up the lamp, he opened the door and went in. A\r
+cold current of air passed them, and the light shot up for a moment in\r
+a flame of murky orange. He shuddered. "Shut the door behind you," he\r
+whispered, as he placed the lamp on the table.\r
+\r
+Hallward glanced round him with a puzzled expression. The room looked\r
+as if it had not been lived in for years. A faded Flemish tapestry, a\r
+curtained picture, an old Italian _cassone_, and an almost empty\r
+book-case--that was all that it seemed to contain, besides a chair and\r
+a table. As Dorian Gray was lighting a half-burned candle that was\r
+standing on the mantelshelf, he saw that the whole place was covered\r
+with dust and that the carpet was in holes. A mouse ran scuffling\r
+behind the wainscoting. There was a damp odour of mildew.\r
+\r
+"So you think that it is only God who sees the soul, Basil? Draw that\r
+curtain back, and you will see mine."\r
+\r
+The voice that spoke was cold and cruel. "You are mad, Dorian, or\r
+playing a part," muttered Hallward, frowning.\r
+\r
+"You won't? Then I must do it myself," said the young man, and he tore\r
+the curtain from its rod and flung it on the ground.\r
+\r
+An exclamation of horror broke from the painter's lips as he saw in the\r
+dim light the hideous face on the canvas grinning at him. There was\r
+something in its expression that filled him with disgust and loathing.\r
+Good heavens! it was Dorian Gray's own face that he was looking at!\r
+The horror, whatever it was, had not yet entirely spoiled that\r
+marvellous beauty. There was still some gold in the thinning hair and\r
+some scarlet on the sensual mouth. The sodden eyes had kept something\r
+of the loveliness of their blue, the noble curves had not yet\r
+completely passed away from chiselled nostrils and from plastic throat.\r
+Yes, it was Dorian himself. But who had done it? He seemed to\r
+recognize his own brushwork, and the frame was his own design. The\r
+idea was monstrous, yet he felt afraid. He seized the lighted candle,\r
+and held it to the picture. In the left-hand corner was his own name,\r
+traced in long letters of bright vermilion.\r
+\r
+It was some foul parody, some infamous ignoble satire. He had never\r
+done that. Still, it was his own picture. He knew it, and he felt as\r
+if his blood had changed in a moment from fire to sluggish ice. His\r
+own picture! What did it mean? Why had it altered? He turned and\r
+looked at Dorian Gray with the eyes of a sick man. His mouth twitched,\r
+and his parched tongue seemed unable to articulate. He passed his hand\r
+across his forehead. It was dank with clammy sweat.\r
+\r
+The young man was leaning against the mantelshelf, watching him with\r
+that strange expression that one sees on the faces of those who are\r
+absorbed in a play when some great artist is acting. There was neither\r
+real sorrow in it nor real joy. There was simply the passion of the\r
+spectator, with perhaps a flicker of triumph in his eyes. He had taken\r
+the flower out of his coat, and was smelling it, or pretending to do so.\r
+\r
+"What does this mean?" cried Hallward, at last. His own voice sounded\r
+shrill and curious in his ears.\r
+\r
+"Years ago, when I was a boy," said Dorian Gray, crushing the flower in\r
+his hand, "you met me, flattered me, and taught me to be vain of my\r
+good looks. One day you introduced me to a friend of yours, who\r
+explained to me the wonder of youth, and you finished a portrait of me\r
+that revealed to me the wonder of beauty. In a mad moment that, even\r
+now, I don't know whether I regret or not, I made a wish, perhaps you\r
+would call it a prayer...."\r
+\r
+"I remember it! Oh, how well I remember it! No! the thing is\r
+impossible. The room is damp. Mildew has got into the canvas. The\r
+paints I used had some wretched mineral poison in them. I tell you the\r
+thing is impossible."\r
+\r
+"Ah, what is impossible?" murmured the young man, going over to the\r
+window and leaning his forehead against the cold, mist-stained glass.\r
+\r
+"You told me you had destroyed it."\r
+\r
+"I was wrong. It has destroyed me."\r
+\r
+"I don't believe it is my picture."\r
+\r
+"Can't you see your ideal in it?" said Dorian bitterly.\r
+\r
+"My ideal, as you call it..."\r
+\r
+"As you called it."\r
+\r
+"There was nothing evil in it, nothing shameful. You were to me such\r
+an ideal as I shall never meet again. This is the face of a satyr."\r
+\r
+"It is the face of my soul."\r
+\r
+"Christ! what a thing I must have worshipped! It has the eyes of a\r
+devil."\r
+\r
+"Each of us has heaven and hell in him, Basil," cried Dorian with a\r
+wild gesture of despair.\r
+\r
+Hallward turned again to the portrait and gazed at it. "My God! If it\r
+is true," he exclaimed, "and this is what you have done with your life,\r
+why, you must be worse even than those who talk against you fancy you\r
+to be!" He held the light up again to the canvas and examined it. The\r
+surface seemed to be quite undisturbed and as he had left it. It was\r
+from within, apparently, that the foulness and horror had come.\r
+Through some strange quickening of inner life the leprosies of sin were\r
+slowly eating the thing away. The rotting of a corpse in a watery\r
+grave was not so fearful.\r
+\r
+His hand shook, and the candle fell from its socket on the floor and\r
+lay there sputtering. He placed his foot on it and put it out. Then\r
+he flung himself into the rickety chair that was standing by the table\r
+and buried his face in his hands.\r
+\r
+"Good God, Dorian, what a lesson! What an awful lesson!" There was no\r
+answer, but he could hear the young man sobbing at the window. "Pray,\r
+Dorian, pray," he murmured. "What is it that one was taught to say in\r
+one's boyhood? 'Lead us not into temptation. Forgive us our sins.\r
+Wash away our iniquities.' Let us say that together. The prayer of\r
+your pride has been answered. The prayer of your repentance will be\r
+answered also. I worshipped you too much. I am punished for it. You\r
+worshipped yourself too much. We are both punished."\r
+\r
+Dorian Gray turned slowly around and looked at him with tear-dimmed\r
+eyes. "It is too late, Basil," he faltered.\r
+\r
+"It is never too late, Dorian. Let us kneel down and try if we cannot\r
+remember a prayer. Isn't there a verse somewhere, 'Though your sins be\r
+as scarlet, yet I will make them as white as snow'?"\r
+\r
+"Those words mean nothing to me now."\r
+\r
+"Hush! Don't say that. You have done enough evil in your life. My\r
+God! Don't you see that accursed thing leering at us?"\r
+\r
+Dorian Gray glanced at the picture, and suddenly an uncontrollable\r
+feeling of hatred for Basil Hallward came over him, as though it had\r
+been suggested to him by the image on the canvas, whispered into his\r
+ear by those grinning lips. The mad passions of a hunted animal\r
+stirred within him, and he loathed the man who was seated at the table,\r
+more than in his whole life he had ever loathed anything. He glanced\r
+wildly around. Something glimmered on the top of the painted chest\r
+that faced him. His eye fell on it. He knew what it was. It was a\r
+knife that he had brought up, some days before, to cut a piece of cord,\r
+and had forgotten to take away with him. He moved slowly towards it,\r
+passing Hallward as he did so. As soon as he got behind him, he seized\r
+it and turned round. Hallward stirred in his chair as if he was going\r
+to rise. He rushed at him and dug the knife into the great vein that\r
+is behind the ear, crushing the man's head down on the table and\r
+stabbing again and again.\r
+\r
+There was a stifled groan and the horrible sound of some one choking\r
+with blood. Three times the outstretched arms shot up convulsively,\r
+waving grotesque, stiff-fingered hands in the air. He stabbed him\r
+twice more, but the man did not move. Something began to trickle on\r
+the floor. He waited for a moment, still pressing the head down. Then\r
+he threw the knife on the table, and listened.\r
+\r
+He could hear nothing, but the drip, drip on the threadbare carpet. He\r
+opened the door and went out on the landing. The house was absolutely\r
+quiet. No one was about. For a few seconds he stood bending over the\r
+balustrade and peering down into the black seething well of darkness.\r
+Then he took out the key and returned to the room, locking himself in\r
+as he did so.\r
+\r
+The thing was still seated in the chair, straining over the table with\r
+bowed head, and humped back, and long fantastic arms. Had it not been\r
+for the red jagged tear in the neck and the clotted black pool that was\r
+slowly widening on the table, one would have said that the man was\r
+simply asleep.\r
+\r
+How quickly it had all been done! He felt strangely calm, and walking\r
+over to the window, opened it and stepped out on the balcony. The wind\r
+had blown the fog away, and the sky was like a monstrous peacock's\r
+tail, starred with myriads of golden eyes. He looked down and saw the\r
+policeman going his rounds and flashing the long beam of his lantern on\r
+the doors of the silent houses. The crimson spot of a prowling hansom\r
+gleamed at the corner and then vanished. A woman in a fluttering shawl\r
+was creeping slowly by the railings, staggering as she went. Now and\r
+then she stopped and peered back. Once, she began to sing in a hoarse\r
+voice. The policeman strolled over and said something to her. She\r
+stumbled away, laughing. A bitter blast swept across the square. The\r
+gas-lamps flickered and became blue, and the leafless trees shook their\r
+black iron branches to and fro. He shivered and went back, closing the\r
+window behind him.\r
+\r
+Having reached the door, he turned the key and opened it. He did not\r
+even glance at the murdered man. He felt that the secret of the whole\r
+thing was not to realize the situation. The friend who had painted the\r
+fatal portrait to which all his misery had been due had gone out of his\r
+life. That was enough.\r
+\r
+Then he remembered the lamp. It was a rather curious one of Moorish\r
+workmanship, made of dull silver inlaid with arabesques of burnished\r
+steel, and studded with coarse turquoises. Perhaps it might be missed\r
+by his servant, and questions would be asked. He hesitated for a\r
+moment, then he turned back and took it from the table. He could not\r
+help seeing the dead thing. How still it was! How horribly white the\r
+long hands looked! It was like a dreadful wax image.\r
+\r
+Having locked the door behind him, he crept quietly downstairs. The\r
+woodwork creaked and seemed to cry out as if in pain. He stopped\r
+several times and waited. No: everything was still. It was merely\r
+the sound of his own footsteps.\r
+\r
+When he reached the library, he saw the bag and coat in the corner.\r
+They must be hidden away somewhere. He unlocked a secret press that\r
+was in the wainscoting, a press in which he kept his own curious\r
+disguises, and put them into it. He could easily burn them afterwards.\r
+Then he pulled out his watch. It was twenty minutes to two.\r
+\r
+He sat down and began to think. Every year--every month, almost--men\r
+were strangled in England for what he had done. There had been a\r
+madness of murder in the air. Some red star had come too close to the\r
+earth.... And yet, what evidence was there against him? Basil Hallward\r
+had left the house at eleven. No one had seen him come in again. Most\r
+of the servants were at Selby Royal. His valet had gone to bed....\r
+Paris! Yes. It was to Paris that Basil had gone, and by the midnight\r
+train, as he had intended. With his curious reserved habits, it would\r
+be months before any suspicions would be roused. Months! Everything\r
+could be destroyed long before then.\r
+\r
+A sudden thought struck him. He put on his fur coat and hat and went\r
+out into the hall. There he paused, hearing the slow heavy tread of\r
+the policeman on the pavement outside and seeing the flash of the\r
+bull's-eye reflected in the window. He waited and held his breath.\r
+\r
+After a few moments he drew back the latch and slipped out, shutting\r
+the door very gently behind him. Then he began ringing the bell. In\r
+about five minutes his valet appeared, half-dressed and looking very\r
+drowsy.\r
+\r
+"I am sorry to have had to wake you up, Francis," he said, stepping in;\r
+"but I had forgotten my latch-key. What time is it?"\r
+\r
+"Ten minutes past two, sir," answered the man, looking at the clock and\r
+blinking.\r
+\r
+"Ten minutes past two? How horribly late! You must wake me at nine\r
+to-morrow. I have some work to do."\r
+\r
+"All right, sir."\r
+\r
+"Did any one call this evening?"\r
+\r
+"Mr. Hallward, sir. He stayed here till eleven, and then he went away\r
+to catch his train."\r
+\r
+"Oh! I am sorry I didn't see him. Did he leave any message?"\r
+\r
+"No, sir, except that he would write to you from Paris, if he did not\r
+find you at the club."\r
+\r
+"That will do, Francis. Don't forget to call me at nine to-morrow."\r
+\r
+"No, sir."\r
+\r
+The man shambled down the passage in his slippers.\r
+\r
+Dorian Gray threw his hat and coat upon the table and passed into the\r
+library. For a quarter of an hour he walked up and down the room,\r
+biting his lip and thinking. Then he took down the Blue Book from one\r
+of the shelves and began to turn over the leaves. "Alan Campbell, 152,\r
+Hertford Street, Mayfair." Yes; that was the man he wanted.\r
+\r
+\r
+\r
+CHAPTER 14\r
+\r
+At nine o'clock the next morning his servant came in with a cup of\r
+chocolate on a tray and opened the shutters. Dorian was sleeping quite\r
+peacefully, lying on his right side, with one hand underneath his\r
+cheek. He looked like a boy who had been tired out with play, or study.\r
+\r
+The man had to touch him twice on the shoulder before he woke, and as\r
+he opened his eyes a faint smile passed across his lips, as though he\r
+had been lost in some delightful dream. Yet he had not dreamed at all.\r
+His night had been untroubled by any images of pleasure or of pain.\r
+But youth smiles without any reason. It is one of its chiefest charms.\r
+\r
+He turned round, and leaning upon his elbow, began to sip his\r
+chocolate. The mellow November sun came streaming into the room. The\r
+sky was bright, and there was a genial warmth in the air. It was\r
+almost like a morning in May.\r
+\r
+Gradually the events of the preceding night crept with silent,\r
+blood-stained feet into his brain and reconstructed themselves there\r
+with terrible distinctness. He winced at the memory of all that he had\r
+suffered, and for a moment the same curious feeling of loathing for\r
+Basil Hallward that had made him kill him as he sat in the chair came\r
+back to him, and he grew cold with passion. The dead man was still\r
+sitting there, too, and in the sunlight now. How horrible that was!\r
+Such hideous things were for the darkness, not for the day.\r
+\r
+He felt that if he brooded on what he had gone through he would sicken\r
+or grow mad. There were sins whose fascination was more in the memory\r
+than in the doing of them, strange triumphs that gratified the pride\r
+more than the passions, and gave to the intellect a quickened sense of\r
+joy, greater than any joy they brought, or could ever bring, to the\r
+senses. But this was not one of them. It was a thing to be driven out\r
+of the mind, to be drugged with poppies, to be strangled lest it might\r
+strangle one itself.\r
+\r
+When the half-hour struck, he passed his hand across his forehead, and\r
+then got up hastily and dressed himself with even more than his usual\r
+care, giving a good deal of attention to the choice of his necktie and\r
+scarf-pin and changing his rings more than once. He spent a long time\r
+also over breakfast, tasting the various dishes, talking to his valet\r
+about some new liveries that he was thinking of getting made for the\r
+servants at Selby, and going through his correspondence. At some of\r
+the letters, he smiled. Three of them bored him. One he read several\r
+times over and then tore up with a slight look of annoyance in his\r
+face. "That awful thing, a woman's memory!" as Lord Henry had once\r
+said.\r
+\r
+After he had drunk his cup of black coffee, he wiped his lips slowly\r
+with a napkin, motioned to his servant to wait, and going over to the\r
+table, sat down and wrote two letters. One he put in his pocket, the\r
+other he handed to the valet.\r
+\r
+"Take this round to 152, Hertford Street, Francis, and if Mr. Campbell\r
+is out of town, get his address."\r
+\r
+As soon as he was alone, he lit a cigarette and began sketching upon a\r
+piece of paper, drawing first flowers and bits of architecture, and\r
+then human faces. Suddenly he remarked that every face that he drew\r
+seemed to have a fantastic likeness to Basil Hallward. He frowned, and\r
+getting up, went over to the book-case and took out a volume at hazard.\r
+He was determined that he would not think about what had happened until\r
+it became absolutely necessary that he should do so.\r
+\r
+When he had stretched himself on the sofa, he looked at the title-page\r
+of the book. It was Gautier's Emaux et Camees, Charpentier's\r
+Japanese-paper edition, with the Jacquemart etching. The binding was\r
+of citron-green leather, with a design of gilt trellis-work and dotted\r
+pomegranates. It had been given to him by Adrian Singleton. As he\r
+turned over the pages, his eye fell on the poem about the hand of\r
+Lacenaire, the cold yellow hand "_du supplice encore mal lavee_," with\r
+its downy red hairs and its "_doigts de faune_." He glanced at his own\r
+white taper fingers, shuddering slightly in spite of himself, and\r
+passed on, till he came to those lovely stanzas upon Venice:\r
+\r
+ Sur une gamme chromatique,\r
+ Le sein de perles ruisselant,\r
+ La Venus de l'Adriatique\r
+ Sort de l'eau son corps rose et blanc.\r
+\r
+ Les domes, sur l'azur des ondes\r
+ Suivant la phrase au pur contour,\r
+ S'enflent comme des gorges rondes\r
+ Que souleve un soupir d'amour.\r
+\r
+ L'esquif aborde et me depose,\r
+ Jetant son amarre au pilier,\r
+ Devant une facade rose,\r
+ Sur le marbre d'un escalier.\r
+\r
+\r
+How exquisite they were! As one read them, one seemed to be floating\r
+down the green water-ways of the pink and pearl city, seated in a black\r
+gondola with silver prow and trailing curtains. The mere lines looked\r
+to him like those straight lines of turquoise-blue that follow one as\r
+one pushes out to the Lido. The sudden flashes of colour reminded him\r
+of the gleam of the opal-and-iris-throated birds that flutter round the\r
+tall honeycombed Campanile, or stalk, with such stately grace, through\r
+the dim, dust-stained arcades. Leaning back with half-closed eyes, he\r
+kept saying over and over to himself:\r
+\r
+ "Devant une facade rose,\r
+ Sur le marbre d'un escalier."\r
+\r
+The whole of Venice was in those two lines. He remembered the autumn\r
+that he had passed there, and a wonderful love that had stirred him to\r
+mad delightful follies. There was romance in every place. But Venice,\r
+like Oxford, had kept the background for romance, and, to the true\r
+romantic, background was everything, or almost everything. Basil had\r
+been with him part of the time, and had gone wild over Tintoret. Poor\r
+Basil! What a horrible way for a man to die!\r
+\r
+He sighed, and took up the volume again, and tried to forget. He read\r
+of the swallows that fly in and out of the little _cafe_ at Smyrna where\r
+the Hadjis sit counting their amber beads and the turbaned merchants\r
+smoke their long tasselled pipes and talk gravely to each other; he\r
+read of the Obelisk in the Place de la Concorde that weeps tears of\r
+granite in its lonely sunless exile and longs to be back by the hot,\r
+lotus-covered Nile, where there are Sphinxes, and rose-red ibises, and\r
+white vultures with gilded claws, and crocodiles with small beryl eyes\r
+that crawl over the green steaming mud; he began to brood over those\r
+verses which, drawing music from kiss-stained marble, tell of that\r
+curious statue that Gautier compares to a contralto voice, the "_monstre\r
+charmant_" that couches in the porphyry-room of the Louvre. But after a\r
+time the book fell from his hand. He grew nervous, and a horrible fit\r
+of terror came over him. What if Alan Campbell should be out of\r
+England? Days would elapse before he could come back. Perhaps he\r
+might refuse to come. What could he do then? Every moment was of\r
+vital importance.\r
+\r
+They had been great friends once, five years before--almost\r
+inseparable, indeed. Then the intimacy had come suddenly to an end.\r
+When they met in society now, it was only Dorian Gray who smiled: Alan\r
+Campbell never did.\r
+\r
+He was an extremely clever young man, though he had no real\r
+appreciation of the visible arts, and whatever little sense of the\r
+beauty of poetry he possessed he had gained entirely from Dorian. His\r
+dominant intellectual passion was for science. At Cambridge he had\r
+spent a great deal of his time working in the laboratory, and had taken\r
+a good class in the Natural Science Tripos of his year. Indeed, he was\r
+still devoted to the study of chemistry, and had a laboratory of his\r
+own in which he used to shut himself up all day long, greatly to the\r
+annoyance of his mother, who had set her heart on his standing for\r
+Parliament and had a vague idea that a chemist was a person who made up\r
+prescriptions. He was an excellent musician, however, as well, and\r
+played both the violin and the piano better than most amateurs. In\r
+fact, it was music that had first brought him and Dorian Gray\r
+together--music and that indefinable attraction that Dorian seemed to\r
+be able to exercise whenever he wished--and, indeed, exercised often\r
+without being conscious of it. They had met at Lady Berkshire's the\r
+night that Rubinstein played there, and after that used to be always\r
+seen together at the opera and wherever good music was going on. For\r
+eighteen months their intimacy lasted. Campbell was always either at\r
+Selby Royal or in Grosvenor Square. To him, as to many others, Dorian\r
+Gray was the type of everything that is wonderful and fascinating in\r
+life. Whether or not a quarrel had taken place between them no one\r
+ever knew. But suddenly people remarked that they scarcely spoke when\r
+they met and that Campbell seemed always to go away early from any\r
+party at which Dorian Gray was present. He had changed, too--was\r
+strangely melancholy at times, appeared almost to dislike hearing\r
+music, and would never himself play, giving as his excuse, when he was\r
+called upon, that he was so absorbed in science that he had no time\r
+left in which to practise. And this was certainly true. Every day he\r
+seemed to become more interested in biology, and his name appeared once\r
+or twice in some of the scientific reviews in connection with certain\r
+curious experiments.\r
+\r
+This was the man Dorian Gray was waiting for. Every second he kept\r
+glancing at the clock. As the minutes went by he became horribly\r
+agitated. At last he got up and began to pace up and down the room,\r
+looking like a beautiful caged thing. He took long stealthy strides.\r
+His hands were curiously cold.\r
+\r
+The suspense became unbearable. Time seemed to him to be crawling with\r
+feet of lead, while he by monstrous winds was being swept towards the\r
+jagged edge of some black cleft of precipice. He knew what was waiting\r
+for him there; saw it, indeed, and, shuddering, crushed with dank hands\r
+his burning lids as though he would have robbed the very brain of sight\r
+and driven the eyeballs back into their cave. It was useless. The\r
+brain had its own food on which it battened, and the imagination, made\r
+grotesque by terror, twisted and distorted as a living thing by pain,\r
+danced like some foul puppet on a stand and grinned through moving\r
+masks. Then, suddenly, time stopped for him. Yes: that blind,\r
+slow-breathing thing crawled no more, and horrible thoughts, time being\r
+dead, raced nimbly on in front, and dragged a hideous future from its\r
+grave, and showed it to him. He stared at it. Its very horror made\r
+him stone.\r
+\r
+At last the door opened and his servant entered. He turned glazed eyes\r
+upon him.\r
+\r
+"Mr. Campbell, sir," said the man.\r
+\r
+A sigh of relief broke from his parched lips, and the colour came back\r
+to his cheeks.\r
+\r
+"Ask him to come in at once, Francis." He felt that he was himself\r
+again. His mood of cowardice had passed away.\r
+\r
+The man bowed and retired. In a few moments, Alan Campbell walked in,\r
+looking very stern and rather pale, his pallor being intensified by his\r
+coal-black hair and dark eyebrows.\r
+\r
+"Alan! This is kind of you. I thank you for coming."\r
+\r
+"I had intended never to enter your house again, Gray. But you said it\r
+was a matter of life and death." His voice was hard and cold. He\r
+spoke with slow deliberation. There was a look of contempt in the\r
+steady searching gaze that he turned on Dorian. He kept his hands in\r
+the pockets of his Astrakhan coat, and seemed not to have noticed the\r
+gesture with which he had been greeted.\r
+\r
+"Yes: it is a matter of life and death, Alan, and to more than one\r
+person. Sit down."\r
+\r
+Campbell took a chair by the table, and Dorian sat opposite to him.\r
+The two men's eyes met. In Dorian's there was infinite pity. He knew\r
+that what he was going to do was dreadful.\r
+\r
+After a strained moment of silence, he leaned across and said, very\r
+quietly, but watching the effect of each word upon the face of him he\r
+had sent for, "Alan, in a locked room at the top of this house, a room\r
+to which nobody but myself has access, a dead man is seated at a table.\r
+He has been dead ten hours now. Don't stir, and don't look at me like\r
+that. Who the man is, why he died, how he died, are matters that do\r
+not concern you. What you have to do is this--"\r
+\r
+"Stop, Gray. I don't want to know anything further. Whether what you\r
+have told me is true or not true doesn't concern me. I entirely\r
+decline to be mixed up in your life. Keep your horrible secrets to\r
+yourself. They don't interest me any more."\r
+\r
+"Alan, they will have to interest you. This one will have to interest\r
+you. I am awfully sorry for you, Alan. But I can't help myself. You\r
+are the one man who is able to save me. I am forced to bring you into\r
+the matter. I have no option. Alan, you are scientific. You know\r
+about chemistry and things of that kind. You have made experiments.\r
+What you have got to do is to destroy the thing that is upstairs--to\r
+destroy it so that not a vestige of it will be left. Nobody saw this\r
+person come into the house. Indeed, at the present moment he is\r
+supposed to be in Paris. He will not be missed for months. When he is\r
+missed, there must be no trace of him found here. You, Alan, you must\r
+change him, and everything that belongs to him, into a handful of ashes\r
+that I may scatter in the air."\r
+\r
+"You are mad, Dorian."\r
+\r
+"Ah! I was waiting for you to call me Dorian."\r
+\r
+"You are mad, I tell you--mad to imagine that I would raise a finger to\r
+help you, mad to make this monstrous confession. I will have nothing\r
+to do with this matter, whatever it is. Do you think I am going to\r
+peril my reputation for you? What is it to me what devil's work you\r
+are up to?"\r
+\r
+"It was suicide, Alan."\r
+\r
+"I am glad of that. But who drove him to it? You, I should fancy."\r
+\r
+"Do you still refuse to do this for me?"\r
+\r
+"Of course I refuse. I will have absolutely nothing to do with it. I\r
+don't care what shame comes on you. You deserve it all. I should not\r
+be sorry to see you disgraced, publicly disgraced. How dare you ask\r
+me, of all men in the world, to mix myself up in this horror? I should\r
+have thought you knew more about people's characters. Your friend Lord\r
+Henry Wotton can't have taught you much about psychology, whatever else\r
+he has taught you. Nothing will induce me to stir a step to help you.\r
+You have come to the wrong man. Go to some of your friends. Don't\r
+come to me."\r
+\r
+"Alan, it was murder. I killed him. You don't know what he had made\r
+me suffer. Whatever my life is, he had more to do with the making or\r
+the marring of it than poor Harry has had. He may not have intended\r
+it, the result was the same."\r
+\r
+"Murder! Good God, Dorian, is that what you have come to? I shall not\r
+inform upon you. It is not my business. Besides, without my stirring\r
+in the matter, you are certain to be arrested. Nobody ever commits a\r
+crime without doing something stupid. But I will have nothing to do\r
+with it."\r
+\r
+"You must have something to do with it. Wait, wait a moment; listen to\r
+me. Only listen, Alan. All I ask of you is to perform a certain\r
+scientific experiment. You go to hospitals and dead-houses, and the\r
+horrors that you do there don't affect you. If in some hideous\r
+dissecting-room or fetid laboratory you found this man lying on a\r
+leaden table with red gutters scooped out in it for the blood to flow\r
+through, you would simply look upon him as an admirable subject. You\r
+would not turn a hair. You would not believe that you were doing\r
+anything wrong. On the contrary, you would probably feel that you were\r
+benefiting the human race, or increasing the sum of knowledge in the\r
+world, or gratifying intellectual curiosity, or something of that kind.\r
+What I want you to do is merely what you have often done before.\r
+Indeed, to destroy a body must be far less horrible than what you are\r
+accustomed to work at. And, remember, it is the only piece of evidence\r
+against me. If it is discovered, I am lost; and it is sure to be\r
+discovered unless you help me."\r
+\r
+"I have no desire to help you. You forget that. I am simply\r
+indifferent to the whole thing. It has nothing to do with me."\r
+\r
+"Alan, I entreat you. Think of the position I am in. Just before you\r
+came I almost fainted with terror. You may know terror yourself some\r
+day. No! don't think of that. Look at the matter purely from the\r
+scientific point of view. You don't inquire where the dead things on\r
+which you experiment come from. Don't inquire now. I have told you\r
+too much as it is. But I beg of you to do this. We were friends once,\r
+Alan."\r
+\r
+"Don't speak about those days, Dorian--they are dead."\r
+\r
+"The dead linger sometimes. The man upstairs will not go away. He is\r
+sitting at the table with bowed head and outstretched arms. Alan!\r
+Alan! If you don't come to my assistance, I am ruined. Why, they will\r
+hang me, Alan! Don't you understand? They will hang me for what I\r
+have done."\r
+\r
+"There is no good in prolonging this scene. I absolutely refuse to do\r
+anything in the matter. It is insane of you to ask me."\r
+\r
+"You refuse?"\r
+\r
+"Yes."\r
+\r
+"I entreat you, Alan."\r
+\r
+"It is useless."\r
+\r
+The same look of pity came into Dorian Gray's eyes. Then he stretched\r
+out his hand, took a piece of paper, and wrote something on it. He\r
+read it over twice, folded it carefully, and pushed it across the\r
+table. Having done this, he got up and went over to the window.\r
+\r
+Campbell looked at him in surprise, and then took up the paper, and\r
+opened it. As he read it, his face became ghastly pale and he fell\r
+back in his chair. A horrible sense of sickness came over him. He\r
+felt as if his heart was beating itself to death in some empty hollow.\r
+\r
+After two or three minutes of terrible silence, Dorian turned round and\r
+came and stood behind him, putting his hand upon his shoulder.\r
+\r
+"I am so sorry for you, Alan," he murmured, "but you leave me no\r
+alternative. I have a letter written already. Here it is. You see\r
+the address. If you don't help me, I must send it. If you don't help\r
+me, I will send it. You know what the result will be. But you are\r
+going to help me. It is impossible for you to refuse now. I tried to\r
+spare you. You will do me the justice to admit that. You were stern,\r
+harsh, offensive. You treated me as no man has ever dared to treat\r
+me--no living man, at any rate. I bore it all. Now it is for me to\r
+dictate terms."\r
+\r
+Campbell buried his face in his hands, and a shudder passed through him.\r
+\r
+"Yes, it is my turn to dictate terms, Alan. You know what they are.\r
+The thing is quite simple. Come, don't work yourself into this fever.\r
+The thing has to be done. Face it, and do it."\r
+\r
+A groan broke from Campbell's lips and he shivered all over. The\r
+ticking of the clock on the mantelpiece seemed to him to be dividing\r
+time into separate atoms of agony, each of which was too terrible to be\r
+borne. He felt as if an iron ring was being slowly tightened round his\r
+forehead, as if the disgrace with which he was threatened had already\r
+come upon him. The hand upon his shoulder weighed like a hand of lead.\r
+It was intolerable. It seemed to crush him.\r
+\r
+"Come, Alan, you must decide at once."\r
+\r
+"I cannot do it," he said, mechanically, as though words could alter\r
+things.\r
+\r
+"You must. You have no choice. Don't delay."\r
+\r
+He hesitated a moment. "Is there a fire in the room upstairs?"\r
+\r
+"Yes, there is a gas-fire with asbestos."\r
+\r
+"I shall have to go home and get some things from the laboratory."\r
+\r
+"No, Alan, you must not leave the house. Write out on a sheet of\r
+notepaper what you want and my servant will take a cab and bring the\r
+things back to you."\r
+\r
+Campbell scrawled a few lines, blotted them, and addressed an envelope\r
+to his assistant. Dorian took the note up and read it carefully. Then\r
+he rang the bell and gave it to his valet, with orders to return as\r
+soon as possible and to bring the things with him.\r
+\r
+As the hall door shut, Campbell started nervously, and having got up\r
+from the chair, went over to the chimney-piece. He was shivering with a\r
+kind of ague. For nearly twenty minutes, neither of the men spoke. A\r
+fly buzzed noisily about the room, and the ticking of the clock was\r
+like the beat of a hammer.\r
+\r
+As the chime struck one, Campbell turned round, and looking at Dorian\r
+Gray, saw that his eyes were filled with tears. There was something in\r
+the purity and refinement of that sad face that seemed to enrage him.\r
+"You are infamous, absolutely infamous!" he muttered.\r
+\r
+"Hush, Alan. You have saved my life," said Dorian.\r
+\r
+"Your life? Good heavens! what a life that is! You have gone from\r
+corruption to corruption, and now you have culminated in crime. In\r
+doing what I am going to do--what you force me to do--it is not of your\r
+life that I am thinking."\r
+\r
+"Ah, Alan," murmured Dorian with a sigh, "I wish you had a thousandth\r
+part of the pity for me that I have for you." He turned away as he\r
+spoke and stood looking out at the garden. Campbell made no answer.\r
+\r
+After about ten minutes a knock came to the door, and the servant\r
+entered, carrying a large mahogany chest of chemicals, with a long coil\r
+of steel and platinum wire and two rather curiously shaped iron clamps.\r
+\r
+"Shall I leave the things here, sir?" he asked Campbell.\r
+\r
+"Yes," said Dorian. "And I am afraid, Francis, that I have another\r
+errand for you. What is the name of the man at Richmond who supplies\r
+Selby with orchids?"\r
+\r
+"Harden, sir."\r
+\r
+"Yes--Harden. You must go down to Richmond at once, see Harden\r
+personally, and tell him to send twice as many orchids as I ordered,\r
+and to have as few white ones as possible. In fact, I don't want any\r
+white ones. It is a lovely day, Francis, and Richmond is a very pretty\r
+place--otherwise I wouldn't bother you about it."\r
+\r
+"No trouble, sir. At what time shall I be back?"\r
+\r
+Dorian looked at Campbell. "How long will your experiment take, Alan?"\r
+he said in a calm indifferent voice. The presence of a third person in\r
+the room seemed to give him extraordinary courage.\r
+\r
+Campbell frowned and bit his lip. "It will take about five hours," he\r
+answered.\r
+\r
+"It will be time enough, then, if you are back at half-past seven,\r
+Francis. Or stay: just leave my things out for dressing. You can\r
+have the evening to yourself. I am not dining at home, so I shall not\r
+want you."\r
+\r
+"Thank you, sir," said the man, leaving the room.\r
+\r
+"Now, Alan, there is not a moment to be lost. How heavy this chest is!\r
+I'll take it for you. You bring the other things." He spoke rapidly\r
+and in an authoritative manner. Campbell felt dominated by him. They\r
+left the room together.\r
+\r
+When they reached the top landing, Dorian took out the key and turned\r
+it in the lock. Then he stopped, and a troubled look came into his\r
+eyes. He shuddered. "I don't think I can go in, Alan," he murmured.\r
+\r
+"It is nothing to me. I don't require you," said Campbell coldly.\r
+\r
+Dorian half opened the door. As he did so, he saw the face of his\r
+portrait leering in the sunlight. On the floor in front of it the torn\r
+curtain was lying. He remembered that the night before he had\r
+forgotten, for the first time in his life, to hide the fatal canvas,\r
+and was about to rush forward, when he drew back with a shudder.\r
+\r
+What was that loathsome red dew that gleamed, wet and glistening, on\r
+one of the hands, as though the canvas had sweated blood? How horrible\r
+it was!--more horrible, it seemed to him for the moment, than the\r
+silent thing that he knew was stretched across the table, the thing\r
+whose grotesque misshapen shadow on the spotted carpet showed him that\r
+it had not stirred, but was still there, as he had left it.\r
+\r
+He heaved a deep breath, opened the door a little wider, and with\r
+half-closed eyes and averted head, walked quickly in, determined that\r
+he would not look even once upon the dead man. Then, stooping down and\r
+taking up the gold-and-purple hanging, he flung it right over the\r
+picture.\r
+\r
+There he stopped, feeling afraid to turn round, and his eyes fixed\r
+themselves on the intricacies of the pattern before him. He heard\r
+Campbell bringing in the heavy chest, and the irons, and the other\r
+things that he had required for his dreadful work. He began to wonder\r
+if he and Basil Hallward had ever met, and, if so, what they had\r
+thought of each other.\r
+\r
+"Leave me now," said a stern voice behind him.\r
+\r
+He turned and hurried out, just conscious that the dead man had been\r
+thrust back into the chair and that Campbell was gazing into a\r
+glistening yellow face. As he was going downstairs, he heard the key\r
+being turned in the lock.\r
+\r
+It was long after seven when Campbell came back into the library. He\r
+was pale, but absolutely calm. "I have done what you asked me to do,"\r
+he muttered. "And now, good-bye. Let us never see each other again."\r
+\r
+"You have saved me from ruin, Alan. I cannot forget that," said Dorian\r
+simply.\r
+\r
+As soon as Campbell had left, he went upstairs. There was a horrible\r
+smell of nitric acid in the room. But the thing that had been sitting\r
+at the table was gone.\r
+\r
+\r
+\r
+CHAPTER 15\r
+\r
+That evening, at eight-thirty, exquisitely dressed and wearing a large\r
+button-hole of Parma violets, Dorian Gray was ushered into Lady\r
+Narborough's drawing-room by bowing servants. His forehead was\r
+throbbing with maddened nerves, and he felt wildly excited, but his\r
+manner as he bent over his hostess's hand was as easy and graceful as\r
+ever. Perhaps one never seems so much at one's ease as when one has to\r
+play a part. Certainly no one looking at Dorian Gray that night could\r
+have believed that he had passed through a tragedy as horrible as any\r
+tragedy of our age. Those finely shaped fingers could never have\r
+clutched a knife for sin, nor those smiling lips have cried out on God\r
+and goodness. He himself could not help wondering at the calm of his\r
+demeanour, and for a moment felt keenly the terrible pleasure of a\r
+double life.\r
+\r
+It was a small party, got up rather in a hurry by Lady Narborough, who\r
+was a very clever woman with what Lord Henry used to describe as the\r
+remains of really remarkable ugliness. She had proved an excellent\r
+wife to one of our most tedious ambassadors, and having buried her\r
+husband properly in a marble mausoleum, which she had herself designed,\r
+and married off her daughters to some rich, rather elderly men, she\r
+devoted herself now to the pleasures of French fiction, French cookery,\r
+and French _esprit_ when she could get it.\r
+\r
+Dorian was one of her especial favourites, and she always told him that\r
+she was extremely glad she had not met him in early life. "I know, my\r
+dear, I should have fallen madly in love with you," she used to say,\r
+"and thrown my bonnet right over the mills for your sake. It is most\r
+fortunate that you were not thought of at the time. As it was, our\r
+bonnets were so unbecoming, and the mills were so occupied in trying to\r
+raise the wind, that I never had even a flirtation with anybody.\r
+However, that was all Narborough's fault. He was dreadfully\r
+short-sighted, and there is no pleasure in taking in a husband who\r
+never sees anything."\r
+\r
+Her guests this evening were rather tedious. The fact was, as she\r
+explained to Dorian, behind a very shabby fan, one of her married\r
+daughters had come up quite suddenly to stay with her, and, to make\r
+matters worse, had actually brought her husband with her. "I think it\r
+is most unkind of her, my dear," she whispered. "Of course I go and\r
+stay with them every summer after I come from Homburg, but then an old\r
+woman like me must have fresh air sometimes, and besides, I really wake\r
+them up. You don't know what an existence they lead down there. It is\r
+pure unadulterated country life. They get up early, because they have\r
+so much to do, and go to bed early, because they have so little to\r
+think about. There has not been a scandal in the neighbourhood since\r
+the time of Queen Elizabeth, and consequently they all fall asleep\r
+after dinner. You shan't sit next either of them. You shall sit by me\r
+and amuse me."\r
+\r
+Dorian murmured a graceful compliment and looked round the room. Yes:\r
+it was certainly a tedious party. Two of the people he had never seen\r
+before, and the others consisted of Ernest Harrowden, one of those\r
+middle-aged mediocrities so common in London clubs who have no enemies,\r
+but are thoroughly disliked by their friends; Lady Ruxton, an\r
+overdressed woman of forty-seven, with a hooked nose, who was always\r
+trying to get herself compromised, but was so peculiarly plain that to\r
+her great disappointment no one would ever believe anything against\r
+her; Mrs. Erlynne, a pushing nobody, with a delightful lisp and\r
+Venetian-red hair; Lady Alice Chapman, his hostess's daughter, a dowdy\r
+dull girl, with one of those characteristic British faces that, once\r
+seen, are never remembered; and her husband, a red-cheeked,\r
+white-whiskered creature who, like so many of his class, was under the\r
+impression that inordinate joviality can atone for an entire lack of\r
+ideas.\r
+\r
+He was rather sorry he had come, till Lady Narborough, looking at the\r
+great ormolu gilt clock that sprawled in gaudy curves on the\r
+mauve-draped mantelshelf, exclaimed: "How horrid of Henry Wotton to be\r
+so late! I sent round to him this morning on chance and he promised\r
+faithfully not to disappoint me."\r
+\r
+It was some consolation that Harry was to be there, and when the door\r
+opened and he heard his slow musical voice lending charm to some\r
+insincere apology, he ceased to feel bored.\r
+\r
+But at dinner he could not eat anything. Plate after plate went away\r
+untasted. Lady Narborough kept scolding him for what she called "an\r
+insult to poor Adolphe, who invented the _menu_ specially for you," and\r
+now and then Lord Henry looked across at him, wondering at his silence\r
+and abstracted manner. From time to time the butler filled his glass\r
+with champagne. He drank eagerly, and his thirst seemed to increase.\r
+\r
+"Dorian," said Lord Henry at last, as the _chaud-froid_ was being handed\r
+round, "what is the matter with you to-night? You are quite out of\r
+sorts."\r
+\r
+"I believe he is in love," cried Lady Narborough, "and that he is\r
+afraid to tell me for fear I should be jealous. He is quite right. I\r
+certainly should."\r
+\r
+"Dear Lady Narborough," murmured Dorian, smiling, "I have not been in\r
+love for a whole week--not, in fact, since Madame de Ferrol left town."\r
+\r
+"How you men can fall in love with that woman!" exclaimed the old lady.\r
+"I really cannot understand it."\r
+\r
+"It is simply because she remembers you when you were a little girl,\r
+Lady Narborough," said Lord Henry. "She is the one link between us and\r
+your short frocks."\r
+\r
+"She does not remember my short frocks at all, Lord Henry. But I\r
+remember her very well at Vienna thirty years ago, and how _decolletee_\r
+she was then."\r
+\r
+"She is still _decolletee_," he answered, taking an olive in his long\r
+fingers; "and when she is in a very smart gown she looks like an\r
+_edition de luxe_ of a bad French novel. She is really wonderful, and\r
+full of surprises. Her capacity for family affection is extraordinary.\r
+When her third husband died, her hair turned quite gold from grief."\r
+\r
+"How can you, Harry!" cried Dorian.\r
+\r
+"It is a most romantic explanation," laughed the hostess. "But her\r
+third husband, Lord Henry! You don't mean to say Ferrol is the fourth?"\r
+\r
+"Certainly, Lady Narborough."\r
+\r
+"I don't believe a word of it."\r
+\r
+"Well, ask Mr. Gray. He is one of her most intimate friends."\r
+\r
+"Is it true, Mr. Gray?"\r
+\r
+"She assures me so, Lady Narborough," said Dorian. "I asked her\r
+whether, like Marguerite de Navarre, she had their hearts embalmed and\r
+hung at her girdle. She told me she didn't, because none of them had\r
+had any hearts at all."\r
+\r
+"Four husbands! Upon my word that is _trop de zele_."\r
+\r
+"_Trop d'audace_, I tell her," said Dorian.\r
+\r
+"Oh! she is audacious enough for anything, my dear. And what is Ferrol\r
+like? I don't know him."\r
+\r
+"The husbands of very beautiful women belong to the criminal classes,"\r
+said Lord Henry, sipping his wine.\r
+\r
+Lady Narborough hit him with her fan. "Lord Henry, I am not at all\r
+surprised that the world says that you are extremely wicked."\r
+\r
+"But what world says that?" asked Lord Henry, elevating his eyebrows.\r
+"It can only be the next world. This world and I are on excellent\r
+terms."\r
+\r
+"Everybody I know says you are very wicked," cried the old lady,\r
+shaking her head.\r
+\r
+Lord Henry looked serious for some moments. "It is perfectly\r
+monstrous," he said, at last, "the way people go about nowadays saying\r
+things against one behind one's back that are absolutely and entirely\r
+true."\r
+\r
+"Isn't he incorrigible?" cried Dorian, leaning forward in his chair.\r
+\r
+"I hope so," said his hostess, laughing. "But really, if you all\r
+worship Madame de Ferrol in this ridiculous way, I shall have to marry\r
+again so as to be in the fashion."\r
+\r
+"You will never marry again, Lady Narborough," broke in Lord Henry.\r
+"You were far too happy. When a woman marries again, it is because she\r
+detested her first husband. When a man marries again, it is because he\r
+adored his first wife. Women try their luck; men risk theirs."\r
+\r
+"Narborough wasn't perfect," cried the old lady.\r
+\r
+"If he had been, you would not have loved him, my dear lady," was the\r
+rejoinder. "Women love us for our defects. If we have enough of them,\r
+they will forgive us everything, even our intellects. You will never\r
+ask me to dinner again after saying this, I am afraid, Lady Narborough,\r
+but it is quite true."\r
+\r
+"Of course it is true, Lord Henry. If we women did not love you for\r
+your defects, where would you all be? Not one of you would ever be\r
+married. You would be a set of unfortunate bachelors. Not, however,\r
+that that would alter you much. Nowadays all the married men live like\r
+bachelors, and all the bachelors like married men."\r
+\r
+"_Fin de siecle_," murmured Lord Henry.\r
+\r
+"_Fin du globe_," answered his hostess.\r
+\r
+"I wish it were _fin du globe_," said Dorian with a sigh. "Life is a\r
+great disappointment."\r
+\r
+"Ah, my dear," cried Lady Narborough, putting on her gloves, "don't\r
+tell me that you have exhausted life. When a man says that one knows\r
+that life has exhausted him. Lord Henry is very wicked, and I\r
+sometimes wish that I had been; but you are made to be good--you look\r
+so good. I must find you a nice wife. Lord Henry, don't you think\r
+that Mr. Gray should get married?"\r
+\r
+"I am always telling him so, Lady Narborough," said Lord Henry with a\r
+bow.\r
+\r
+"Well, we must look out for a suitable match for him. I shall go\r
+through Debrett carefully to-night and draw out a list of all the\r
+eligible young ladies."\r
+\r
+"With their ages, Lady Narborough?" asked Dorian.\r
+\r
+"Of course, with their ages, slightly edited. But nothing must be done\r
+in a hurry. I want it to be what _The Morning Post_ calls a suitable\r
+alliance, and I want you both to be happy."\r
+\r
+"What nonsense people talk about happy marriages!" exclaimed Lord\r
+Henry. "A man can be happy with any woman, as long as he does not love\r
+her."\r
+\r
+"Ah! what a cynic you are!" cried the old lady, pushing back her chair\r
+and nodding to Lady Ruxton. "You must come and dine with me soon\r
+again. You are really an admirable tonic, much better than what Sir\r
+Andrew prescribes for me. You must tell me what people you would like\r
+to meet, though. I want it to be a delightful gathering."\r
+\r
+"I like men who have a future and women who have a past," he answered.\r
+"Or do you think that would make it a petticoat party?"\r
+\r
+"I fear so," she said, laughing, as she stood up. "A thousand pardons,\r
+my dear Lady Ruxton," she added, "I didn't see you hadn't finished your\r
+cigarette."\r
+\r
+"Never mind, Lady Narborough. I smoke a great deal too much. I am\r
+going to limit myself, for the future."\r
+\r
+"Pray don't, Lady Ruxton," said Lord Henry. "Moderation is a fatal\r
+thing. Enough is as bad as a meal. More than enough is as good as a\r
+feast."\r
+\r
+Lady Ruxton glanced at him curiously. "You must come and explain that\r
+to me some afternoon, Lord Henry. It sounds a fascinating theory," she\r
+murmured, as she swept out of the room.\r
+\r
+"Now, mind you don't stay too long over your politics and scandal,"\r
+cried Lady Narborough from the door. "If you do, we are sure to\r
+squabble upstairs."\r
+\r
+The men laughed, and Mr. Chapman got up solemnly from the foot of the\r
+table and came up to the top. Dorian Gray changed his seat and went\r
+and sat by Lord Henry. Mr. Chapman began to talk in a loud voice about\r
+the situation in the House of Commons. He guffawed at his adversaries.\r
+The word _doctrinaire_--word full of terror to the British\r
+mind--reappeared from time to time between his explosions. An\r
+alliterative prefix served as an ornament of oratory. He hoisted the\r
+Union Jack on the pinnacles of thought. The inherited stupidity of the\r
+race--sound English common sense he jovially termed it--was shown to be\r
+the proper bulwark for society.\r
+\r
+A smile curved Lord Henry's lips, and he turned round and looked at\r
+Dorian.\r
+\r
+"Are you better, my dear fellow?" he asked. "You seemed rather out of\r
+sorts at dinner."\r
+\r
+"I am quite well, Harry. I am tired. That is all."\r
+\r
+"You were charming last night. The little duchess is quite devoted to\r
+you. She tells me she is going down to Selby."\r
+\r
+"She has promised to come on the twentieth."\r
+\r
+"Is Monmouth to be there, too?"\r
+\r
+"Oh, yes, Harry."\r
+\r
+"He bores me dreadfully, almost as much as he bores her. She is very\r
+clever, too clever for a woman. She lacks the indefinable charm of\r
+weakness. It is the feet of clay that make the gold of the image\r
+precious. Her feet are very pretty, but they are not feet of clay.\r
+White porcelain feet, if you like. They have been through the fire,\r
+and what fire does not destroy, it hardens. She has had experiences."\r
+\r
+"How long has she been married?" asked Dorian.\r
+\r
+"An eternity, she tells me. I believe, according to the peerage, it is\r
+ten years, but ten years with Monmouth must have been like eternity,\r
+with time thrown in. Who else is coming?"\r
+\r
+"Oh, the Willoughbys, Lord Rugby and his wife, our hostess, Geoffrey\r
+Clouston, the usual set. I have asked Lord Grotrian."\r
+\r
+"I like him," said Lord Henry. "A great many people don't, but I find\r
+him charming. He atones for being occasionally somewhat overdressed by\r
+being always absolutely over-educated. He is a very modern type."\r
+\r
+"I don't know if he will be able to come, Harry. He may have to go to\r
+Monte Carlo with his father."\r
+\r
+"Ah! what a nuisance people's people are! Try and make him come. By\r
+the way, Dorian, you ran off very early last night. You left before\r
+eleven. What did you do afterwards? Did you go straight home?"\r
+\r
+Dorian glanced at him hurriedly and frowned.\r
+\r
+"No, Harry," he said at last, "I did not get home till nearly three."\r
+\r
+"Did you go to the club?"\r
+\r
+"Yes," he answered. Then he bit his lip. "No, I don't mean that. I\r
+didn't go to the club. I walked about. I forget what I did.... How\r
+inquisitive you are, Harry! You always want to know what one has been\r
+doing. I always want to forget what I have been doing. I came in at\r
+half-past two, if you wish to know the exact time. I had left my\r
+latch-key at home, and my servant had to let me in. If you want any\r
+corroborative evidence on the subject, you can ask him."\r
+\r
+Lord Henry shrugged his shoulders. "My dear fellow, as if I cared!\r
+Let us go up to the drawing-room. No sherry, thank you, Mr. Chapman.\r
+Something has happened to you, Dorian. Tell me what it is. You are\r
+not yourself to-night."\r
+\r
+"Don't mind me, Harry. I am irritable, and out of temper. I shall\r
+come round and see you to-morrow, or next day. Make my excuses to Lady\r
+Narborough. I shan't go upstairs. I shall go home. I must go home."\r
+\r
+"All right, Dorian. I dare say I shall see you to-morrow at tea-time.\r
+The duchess is coming."\r
+\r
+"I will try to be there, Harry," he said, leaving the room. As he\r
+drove back to his own house, he was conscious that the sense of terror\r
+he thought he had strangled had come back to him. Lord Henry's casual\r
+questioning had made him lose his nerve for the moment, and he wanted\r
+his nerve still. Things that were dangerous had to be destroyed. He\r
+winced. He hated the idea of even touching them.\r
+\r
+Yet it had to be done. He realized that, and when he had locked the\r
+door of his library, he opened the secret press into which he had\r
+thrust Basil Hallward's coat and bag. A huge fire was blazing. He\r
+piled another log on it. The smell of the singeing clothes and burning\r
+leather was horrible. It took him three-quarters of an hour to consume\r
+everything. At the end he felt faint and sick, and having lit some\r
+Algerian pastilles in a pierced copper brazier, he bathed his hands and\r
+forehead with a cool musk-scented vinegar.\r
+\r
+Suddenly he started. His eyes grew strangely bright, and he gnawed\r
+nervously at his underlip. Between two of the windows stood a large\r
+Florentine cabinet, made out of ebony and inlaid with ivory and blue\r
+lapis. He watched it as though it were a thing that could fascinate\r
+and make afraid, as though it held something that he longed for and yet\r
+almost loathed. His breath quickened. A mad craving came over him.\r
+He lit a cigarette and then threw it away. His eyelids drooped till\r
+the long fringed lashes almost touched his cheek. But he still watched\r
+the cabinet. At last he got up from the sofa on which he had been\r
+lying, went over to it, and having unlocked it, touched some hidden\r
+spring. A triangular drawer passed slowly out. His fingers moved\r
+instinctively towards it, dipped in, and closed on something. It was a\r
+small Chinese box of black and gold-dust lacquer, elaborately wrought,\r
+the sides patterned with curved waves, and the silken cords hung with\r
+round crystals and tasselled in plaited metal threads. He opened it.\r
+Inside was a green paste, waxy in lustre, the odour curiously heavy and\r
+persistent.\r
+\r
+He hesitated for some moments, with a strangely immobile smile upon his\r
+face. Then shivering, though the atmosphere of the room was terribly\r
+hot, he drew himself up and glanced at the clock. It was twenty\r
+minutes to twelve. He put the box back, shutting the cabinet doors as\r
+he did so, and went into his bedroom.\r
+\r
+As midnight was striking bronze blows upon the dusky air, Dorian Gray,\r
+dressed commonly, and with a muffler wrapped round his throat, crept\r
+quietly out of his house. In Bond Street he found a hansom with a good\r
+horse. He hailed it and in a low voice gave the driver an address.\r
+\r
+The man shook his head. "It is too far for me," he muttered.\r
+\r
+"Here is a sovereign for you," said Dorian. "You shall have another if\r
+you drive fast."\r
+\r
+"All right, sir," answered the man, "you will be there in an hour," and\r
+after his fare had got in he turned his horse round and drove rapidly\r
+towards the river.\r
+\r
+\r
+\r
+CHAPTER 16\r
+\r
+A cold rain began to fall, and the blurred street-lamps looked ghastly\r
+in the dripping mist. The public-houses were just closing, and dim men\r
+and women were clustering in broken groups round their doors. From\r
+some of the bars came the sound of horrible laughter. In others,\r
+drunkards brawled and screamed.\r
+\r
+Lying back in the hansom, with his hat pulled over his forehead, Dorian\r
+Gray watched with listless eyes the sordid shame of the great city, and\r
+now and then he repeated to himself the words that Lord Henry had said\r
+to him on the first day they had met, "To cure the soul by means of the\r
+senses, and the senses by means of the soul." Yes, that was the\r
+secret. He had often tried it, and would try it again now. There were\r
+opium dens where one could buy oblivion, dens of horror where the\r
+memory of old sins could be destroyed by the madness of sins that were\r
+new.\r
+\r
+The moon hung low in the sky like a yellow skull. From time to time a\r
+huge misshapen cloud stretched a long arm across and hid it. The\r
+gas-lamps grew fewer, and the streets more narrow and gloomy. Once the\r
+man lost his way and had to drive back half a mile. A steam rose from\r
+the horse as it splashed up the puddles. The sidewindows of the hansom\r
+were clogged with a grey-flannel mist.\r
+\r
+"To cure the soul by means of the senses, and the senses by means of\r
+the soul!" How the words rang in his ears! His soul, certainly, was\r
+sick to death. Was it true that the senses could cure it? Innocent\r
+blood had been spilled. What could atone for that? Ah! for that there\r
+was no atonement; but though forgiveness was impossible, forgetfulness\r
+was possible still, and he was determined to forget, to stamp the thing\r
+out, to crush it as one would crush the adder that had stung one.\r
+Indeed, what right had Basil to have spoken to him as he had done? Who\r
+had made him a judge over others? He had said things that were\r
+dreadful, horrible, not to be endured.\r
+\r
+On and on plodded the hansom, going slower, it seemed to him, at each\r
+step. He thrust up the trap and called to the man to drive faster.\r
+The hideous hunger for opium began to gnaw at him. His throat burned\r
+and his delicate hands twitched nervously together. He struck at the\r
+horse madly with his stick. The driver laughed and whipped up. He\r
+laughed in answer, and the man was silent.\r
+\r
+The way seemed interminable, and the streets like the black web of some\r
+sprawling spider. The monotony became unbearable, and as the mist\r
+thickened, he felt afraid.\r
+\r
+Then they passed by lonely brickfields. The fog was lighter here, and\r
+he could see the strange, bottle-shaped kilns with their orange,\r
+fanlike tongues of fire. A dog barked as they went by, and far away in\r
+the darkness some wandering sea-gull screamed. The horse stumbled in a\r
+rut, then swerved aside and broke into a gallop.\r
+\r
+After some time they left the clay road and rattled again over\r
+rough-paven streets. Most of the windows were dark, but now and then\r
+fantastic shadows were silhouetted against some lamplit blind. He\r
+watched them curiously. They moved like monstrous marionettes and made\r
+gestures like live things. He hated them. A dull rage was in his\r
+heart. As they turned a corner, a woman yelled something at them from\r
+an open door, and two men ran after the hansom for about a hundred\r
+yards. The driver beat at them with his whip.\r
+\r
+It is said that passion makes one think in a circle. Certainly with\r
+hideous iteration the bitten lips of Dorian Gray shaped and reshaped\r
+those subtle words that dealt with soul and sense, till he had found in\r
+them the full expression, as it were, of his mood, and justified, by\r
+intellectual approval, passions that without such justification would\r
+still have dominated his temper. From cell to cell of his brain crept\r
+the one thought; and the wild desire to live, most terrible of all\r
+man's appetites, quickened into force each trembling nerve and fibre.\r
+Ugliness that had once been hateful to him because it made things real,\r
+became dear to him now for that very reason. Ugliness was the one\r
+reality. The coarse brawl, the loathsome den, the crude violence of\r
+disordered life, the very vileness of thief and outcast, were more\r
+vivid, in their intense actuality of impression, than all the gracious\r
+shapes of art, the dreamy shadows of song. They were what he needed\r
+for forgetfulness. In three days he would be free.\r
+\r
+Suddenly the man drew up with a jerk at the top of a dark lane. Over\r
+the low roofs and jagged chimney-stacks of the houses rose the black\r
+masts of ships. Wreaths of white mist clung like ghostly sails to the\r
+yards.\r
+\r
+"Somewhere about here, sir, ain't it?" he asked huskily through the\r
+trap.\r
+\r
+Dorian started and peered round. "This will do," he answered, and\r
+having got out hastily and given the driver the extra fare he had\r
+promised him, he walked quickly in the direction of the quay. Here and\r
+there a lantern gleamed at the stern of some huge merchantman. The\r
+light shook and splintered in the puddles. A red glare came from an\r
+outward-bound steamer that was coaling. The slimy pavement looked like\r
+a wet mackintosh.\r
+\r
+He hurried on towards the left, glancing back now and then to see if he\r
+was being followed. In about seven or eight minutes he reached a small\r
+shabby house that was wedged in between two gaunt factories. In one of\r
+the top-windows stood a lamp. He stopped and gave a peculiar knock.\r
+\r
+After a little time he heard steps in the passage and the chain being\r
+unhooked. The door opened quietly, and he went in without saying a\r
+word to the squat misshapen figure that flattened itself into the\r
+shadow as he passed. At the end of the hall hung a tattered green\r
+curtain that swayed and shook in the gusty wind which had followed him\r
+in from the street. He dragged it aside and entered a long low room\r
+which looked as if it had once been a third-rate dancing-saloon. Shrill\r
+flaring gas-jets, dulled and distorted in the fly-blown mirrors that\r
+faced them, were ranged round the walls. Greasy reflectors of ribbed\r
+tin backed them, making quivering disks of light. The floor was\r
+covered with ochre-coloured sawdust, trampled here and there into mud,\r
+and stained with dark rings of spilled liquor. Some Malays were\r
+crouching by a little charcoal stove, playing with bone counters and\r
+showing their white teeth as they chattered. In one corner, with his\r
+head buried in his arms, a sailor sprawled over a table, and by the\r
+tawdrily painted bar that ran across one complete side stood two\r
+haggard women, mocking an old man who was brushing the sleeves of his\r
+coat with an expression of disgust. "He thinks he's got red ants on\r
+him," laughed one of them, as Dorian passed by. The man looked at her\r
+in terror and began to whimper.\r
+\r
+At the end of the room there was a little staircase, leading to a\r
+darkened chamber. As Dorian hurried up its three rickety steps, the\r
+heavy odour of opium met him. He heaved a deep breath, and his\r
+nostrils quivered with pleasure. When he entered, a young man with\r
+smooth yellow hair, who was bending over a lamp lighting a long thin\r
+pipe, looked up at him and nodded in a hesitating manner.\r
+\r
+"You here, Adrian?" muttered Dorian.\r
+\r
+"Where else should I be?" he answered, listlessly. "None of the chaps\r
+will speak to me now."\r
+\r
+"I thought you had left England."\r
+\r
+"Darlington is not going to do anything. My brother paid the bill at\r
+last. George doesn't speak to me either.... I don't care," he added\r
+with a sigh. "As long as one has this stuff, one doesn't want friends.\r
+I think I have had too many friends."\r
+\r
+Dorian winced and looked round at the grotesque things that lay in such\r
+fantastic postures on the ragged mattresses. The twisted limbs, the\r
+gaping mouths, the staring lustreless eyes, fascinated him. He knew in\r
+what strange heavens they were suffering, and what dull hells were\r
+teaching them the secret of some new joy. They were better off than he\r
+was. He was prisoned in thought. Memory, like a horrible malady, was\r
+eating his soul away. From time to time he seemed to see the eyes of\r
+Basil Hallward looking at him. Yet he felt he could not stay. The\r
+presence of Adrian Singleton troubled him. He wanted to be where no\r
+one would know who he was. He wanted to escape from himself.\r
+\r
+"I am going on to the other place," he said after a pause.\r
+\r
+"On the wharf?"\r
+\r
+"Yes."\r
+\r
+"That mad-cat is sure to be there. They won't have her in this place\r
+now."\r
+\r
+Dorian shrugged his shoulders. "I am sick of women who love one.\r
+Women who hate one are much more interesting. Besides, the stuff is\r
+better."\r
+\r
+"Much the same."\r
+\r
+"I like it better. Come and have something to drink. I must have\r
+something."\r
+\r
+"I don't want anything," murmured the young man.\r
+\r
+"Never mind."\r
+\r
+Adrian Singleton rose up wearily and followed Dorian to the bar. A\r
+half-caste, in a ragged turban and a shabby ulster, grinned a hideous\r
+greeting as he thrust a bottle of brandy and two tumblers in front of\r
+them. The women sidled up and began to chatter. Dorian turned his\r
+back on them and said something in a low voice to Adrian Singleton.\r
+\r
+A crooked smile, like a Malay crease, writhed across the face of one of\r
+the women. "We are very proud to-night," she sneered.\r
+\r
+"For God's sake don't talk to me," cried Dorian, stamping his foot on\r
+the ground. "What do you want? Money? Here it is. Don't ever talk\r
+to me again."\r
+\r
+Two red sparks flashed for a moment in the woman's sodden eyes, then\r
+flickered out and left them dull and glazed. She tossed her head and\r
+raked the coins off the counter with greedy fingers. Her companion\r
+watched her enviously.\r
+\r
+"It's no use," sighed Adrian Singleton. "I don't care to go back.\r
+What does it matter? I am quite happy here."\r
+\r
+"You will write to me if you want anything, won't you?" said Dorian,\r
+after a pause.\r
+\r
+"Perhaps."\r
+\r
+"Good night, then."\r
+\r
+"Good night," answered the young man, passing up the steps and wiping\r
+his parched mouth with a handkerchief.\r
+\r
+Dorian walked to the door with a look of pain in his face. As he drew\r
+the curtain aside, a hideous laugh broke from the painted lips of the\r
+woman who had taken his money. "There goes the devil's bargain!" she\r
+hiccoughed, in a hoarse voice.\r
+\r
+"Curse you!" he answered, "don't call me that."\r
+\r
+She snapped her fingers. "Prince Charming is what you like to be\r
+called, ain't it?" she yelled after him.\r
+\r
+The drowsy sailor leaped to his feet as she spoke, and looked wildly\r
+round. The sound of the shutting of the hall door fell on his ear. He\r
+rushed out as if in pursuit.\r
+\r
+Dorian Gray hurried along the quay through the drizzling rain. His\r
+meeting with Adrian Singleton had strangely moved him, and he wondered\r
+if the ruin of that young life was really to be laid at his door, as\r
+Basil Hallward had said to him with such infamy of insult. He bit his\r
+lip, and for a few seconds his eyes grew sad. Yet, after all, what did\r
+it matter to him? One's days were too brief to take the burden of\r
+another's errors on one's shoulders. Each man lived his own life and\r
+paid his own price for living it. The only pity was one had to pay so\r
+often for a single fault. One had to pay over and over again, indeed.\r
+In her dealings with man, destiny never closed her accounts.\r
+\r
+There are moments, psychologists tell us, when the passion for sin, or\r
+for what the world calls sin, so dominates a nature that every fibre of\r
+the body, as every cell of the brain, seems to be instinct with fearful\r
+impulses. Men and women at such moments lose the freedom of their\r
+will. They move to their terrible end as automatons move. Choice is\r
+taken from them, and conscience is either killed, or, if it lives at\r
+all, lives but to give rebellion its fascination and disobedience its\r
+charm. For all sins, as theologians weary not of reminding us, are\r
+sins of disobedience. When that high spirit, that morning star of\r
+evil, fell from heaven, it was as a rebel that he fell.\r
+\r
+Callous, concentrated on evil, with stained mind, and soul hungry for\r
+rebellion, Dorian Gray hastened on, quickening his step as he went, but\r
+as he darted aside into a dim archway, that had served him often as a\r
+short cut to the ill-famed place where he was going, he felt himself\r
+suddenly seized from behind, and before he had time to defend himself,\r
+he was thrust back against the wall, with a brutal hand round his\r
+throat.\r
+\r
+He struggled madly for life, and by a terrible effort wrenched the\r
+tightening fingers away. In a second he heard the click of a revolver,\r
+and saw the gleam of a polished barrel, pointing straight at his head,\r
+and the dusky form of a short, thick-set man facing him.\r
+\r
+"What do you want?" he gasped.\r
+\r
+"Keep quiet," said the man. "If you stir, I shoot you."\r
+\r
+"You are mad. What have I done to you?"\r
+\r
+"You wrecked the life of Sibyl Vane," was the answer, "and Sibyl Vane\r
+was my sister. She killed herself. I know it. Her death is at your\r
+door. I swore I would kill you in return. For years I have sought\r
+you. I had no clue, no trace. The two people who could have described\r
+you were dead. I knew nothing of you but the pet name she used to call\r
+you. I heard it to-night by chance. Make your peace with God, for\r
+to-night you are going to die."\r
+\r
+Dorian Gray grew sick with fear. "I never knew her," he stammered. "I\r
+never heard of her. You are mad."\r
+\r
+"You had better confess your sin, for as sure as I am James Vane, you\r
+are going to die." There was a horrible moment. Dorian did not know\r
+what to say or do. "Down on your knees!" growled the man. "I give you\r
+one minute to make your peace--no more. I go on board to-night for\r
+India, and I must do my job first. One minute. That's all."\r
+\r
+Dorian's arms fell to his side. Paralysed with terror, he did not know\r
+what to do. Suddenly a wild hope flashed across his brain. "Stop," he\r
+cried. "How long ago is it since your sister died? Quick, tell me!"\r
+\r
+"Eighteen years," said the man. "Why do you ask me? What do years\r
+matter?"\r
+\r
+"Eighteen years," laughed Dorian Gray, with a touch of triumph in his\r
+voice. "Eighteen years! Set me under the lamp and look at my face!"\r
+\r
+James Vane hesitated for a moment, not understanding what was meant.\r
+Then he seized Dorian Gray and dragged him from the archway.\r
+\r
+Dim and wavering as was the wind-blown light, yet it served to show him\r
+the hideous error, as it seemed, into which he had fallen, for the face\r
+of the man he had sought to kill had all the bloom of boyhood, all the\r
+unstained purity of youth. He seemed little more than a lad of twenty\r
+summers, hardly older, if older indeed at all, than his sister had been\r
+when they had parted so many years ago. It was obvious that this was\r
+not the man who had destroyed her life.\r
+\r
+He loosened his hold and reeled back. "My God! my God!" he cried, "and\r
+I would have murdered you!"\r
+\r
+Dorian Gray drew a long breath. "You have been on the brink of\r
+committing a terrible crime, my man," he said, looking at him sternly.\r
+"Let this be a warning to you not to take vengeance into your own\r
+hands."\r
+\r
+"Forgive me, sir," muttered James Vane. "I was deceived. A chance\r
+word I heard in that damned den set me on the wrong track."\r
+\r
+"You had better go home and put that pistol away, or you may get into\r
+trouble," said Dorian, turning on his heel and going slowly down the\r
+street.\r
+\r
+James Vane stood on the pavement in horror. He was trembling from head\r
+to foot. After a little while, a black shadow that had been creeping\r
+along the dripping wall moved out into the light and came close to him\r
+with stealthy footsteps. He felt a hand laid on his arm and looked\r
+round with a start. It was one of the women who had been drinking at\r
+the bar.\r
+\r
+"Why didn't you kill him?" she hissed out, putting haggard face quite\r
+close to his. "I knew you were following him when you rushed out from\r
+Daly's. You fool! You should have killed him. He has lots of money,\r
+and he's as bad as bad."\r
+\r
+"He is not the man I am looking for," he answered, "and I want no man's\r
+money. I want a man's life. The man whose life I want must be nearly\r
+forty now. This one is little more than a boy. Thank God, I have not\r
+got his blood upon my hands."\r
+\r
+The woman gave a bitter laugh. "Little more than a boy!" she sneered.\r
+"Why, man, it's nigh on eighteen years since Prince Charming made me\r
+what I am."\r
+\r
+"You lie!" cried James Vane.\r
+\r
+She raised her hand up to heaven. "Before God I am telling the truth,"\r
+she cried.\r
+\r
+"Before God?"\r
+\r
+"Strike me dumb if it ain't so. He is the worst one that comes here.\r
+They say he has sold himself to the devil for a pretty face. It's nigh\r
+on eighteen years since I met him. He hasn't changed much since then.\r
+I have, though," she added, with a sickly leer.\r
+\r
+"You swear this?"\r
+\r
+"I swear it," came in hoarse echo from her flat mouth. "But don't give\r
+me away to him," she whined; "I am afraid of him. Let me have some\r
+money for my night's lodging."\r
+\r
+He broke from her with an oath and rushed to the corner of the street,\r
+but Dorian Gray had disappeared. When he looked back, the woman had\r
+vanished also.\r
+\r
+\r
+\r
+CHAPTER 17\r
+\r
+A week later Dorian Gray was sitting in the conservatory at Selby\r
+Royal, talking to the pretty Duchess of Monmouth, who with her husband,\r
+a jaded-looking man of sixty, was amongst his guests. It was tea-time,\r
+and the mellow light of the huge, lace-covered lamp that stood on the\r
+table lit up the delicate china and hammered silver of the service at\r
+which the duchess was presiding. Her white hands were moving daintily\r
+among the cups, and her full red lips were smiling at something that\r
+Dorian had whispered to her. Lord Henry was lying back in a\r
+silk-draped wicker chair, looking at them. On a peach-coloured divan\r
+sat Lady Narborough, pretending to listen to the duke's description of\r
+the last Brazilian beetle that he had added to his collection. Three\r
+young men in elaborate smoking-suits were handing tea-cakes to some of\r
+the women. The house-party consisted of twelve people, and there were\r
+more expected to arrive on the next day.\r
+\r
+"What are you two talking about?" said Lord Henry, strolling over to\r
+the table and putting his cup down. "I hope Dorian has told you about\r
+my plan for rechristening everything, Gladys. It is a delightful idea."\r
+\r
+"But I don't want to be rechristened, Harry," rejoined the duchess,\r
+looking up at him with her wonderful eyes. "I am quite satisfied with\r
+my own name, and I am sure Mr. Gray should be satisfied with his."\r
+\r
+"My dear Gladys, I would not alter either name for the world. They are\r
+both perfect. I was thinking chiefly of flowers. Yesterday I cut an\r
+orchid, for my button-hole. It was a marvellous spotted thing, as\r
+effective as the seven deadly sins. In a thoughtless moment I asked\r
+one of the gardeners what it was called. He told me it was a fine\r
+specimen of _Robinsoniana_, or something dreadful of that kind. It is a\r
+sad truth, but we have lost the faculty of giving lovely names to\r
+things. Names are everything. I never quarrel with actions. My one\r
+quarrel is with words. That is the reason I hate vulgar realism in\r
+literature. The man who could call a spade a spade should be compelled\r
+to use one. It is the only thing he is fit for."\r
+\r
+"Then what should we call you, Harry?" she asked.\r
+\r
+"His name is Prince Paradox," said Dorian.\r
+\r
+"I recognize him in a flash," exclaimed the duchess.\r
+\r
+"I won't hear of it," laughed Lord Henry, sinking into a chair. "From\r
+a label there is no escape! I refuse the title."\r
+\r
+"Royalties may not abdicate," fell as a warning from pretty lips.\r
+\r
+"You wish me to defend my throne, then?"\r
+\r
+"Yes."\r
+\r
+"I give the truths of to-morrow."\r
+\r
+"I prefer the mistakes of to-day," she answered.\r
+\r
+"You disarm me, Gladys," he cried, catching the wilfulness of her mood.\r
+\r
+"Of your shield, Harry, not of your spear."\r
+\r
+"I never tilt against beauty," he said, with a wave of his hand.\r
+\r
+"That is your error, Harry, believe me. You value beauty far too much."\r
+\r
+"How can you say that? I admit that I think that it is better to be\r
+beautiful than to be good. But on the other hand, no one is more ready\r
+than I am to acknowledge that it is better to be good than to be ugly."\r
+\r
+"Ugliness is one of the seven deadly sins, then?" cried the duchess.\r
+"What becomes of your simile about the orchid?"\r
+\r
+"Ugliness is one of the seven deadly virtues, Gladys. You, as a good\r
+Tory, must not underrate them. Beer, the Bible, and the seven deadly\r
+virtues have made our England what she is."\r
+\r
+"You don't like your country, then?" she asked.\r
+\r
+"I live in it."\r
+\r
+"That you may censure it the better."\r
+\r
+"Would you have me take the verdict of Europe on it?" he inquired.\r
+\r
+"What do they say of us?"\r
+\r
+"That Tartuffe has emigrated to England and opened a shop."\r
+\r
+"Is that yours, Harry?"\r
+\r
+"I give it to you."\r
+\r
+"I could not use it. It is too true."\r
+\r
+"You need not be afraid. Our countrymen never recognize a description."\r
+\r
+"They are practical."\r
+\r
+"They are more cunning than practical. When they make up their ledger,\r
+they balance stupidity by wealth, and vice by hypocrisy."\r
+\r
+"Still, we have done great things."\r
+\r
+"Great things have been thrust on us, Gladys."\r
+\r
+"We have carried their burden."\r
+\r
+"Only as far as the Stock Exchange."\r
+\r
+She shook her head. "I believe in the race," she cried.\r
+\r
+"It represents the survival of the pushing."\r
+\r
+"It has development."\r
+\r
+"Decay fascinates me more."\r
+\r
+"What of art?" she asked.\r
+\r
+"It is a malady."\r
+\r
+"Love?"\r
+\r
+"An illusion."\r
+\r
+"Religion?"\r
+\r
+"The fashionable substitute for belief."\r
+\r
+"You are a sceptic."\r
+\r
+"Never! Scepticism is the beginning of faith."\r
+\r
+"What are you?"\r
+\r
+"To define is to limit."\r
+\r
+"Give me a clue."\r
+\r
+"Threads snap. You would lose your way in the labyrinth."\r
+\r
+"You bewilder me. Let us talk of some one else."\r
+\r
+"Our host is a delightful topic. Years ago he was christened Prince\r
+Charming."\r
+\r
+"Ah! don't remind me of that," cried Dorian Gray.\r
+\r
+"Our host is rather horrid this evening," answered the duchess,\r
+colouring. "I believe he thinks that Monmouth married me on purely\r
+scientific principles as the best specimen he could find of a modern\r
+butterfly."\r
+\r
+"Well, I hope he won't stick pins into you, Duchess," laughed Dorian.\r
+\r
+"Oh! my maid does that already, Mr. Gray, when she is annoyed with me."\r
+\r
+"And what does she get annoyed with you about, Duchess?"\r
+\r
+"For the most trivial things, Mr. Gray, I assure you. Usually because\r
+I come in at ten minutes to nine and tell her that I must be dressed by\r
+half-past eight."\r
+\r
+"How unreasonable of her! You should give her warning."\r
+\r
+"I daren't, Mr. Gray. Why, she invents hats for me. You remember the\r
+one I wore at Lady Hilstone's garden-party? You don't, but it is nice\r
+of you to pretend that you do. Well, she made it out of nothing. All\r
+good hats are made out of nothing."\r
+\r
+"Like all good reputations, Gladys," interrupted Lord Henry. "Every\r
+effect that one produces gives one an enemy. To be popular one must be\r
+a mediocrity."\r
+\r
+"Not with women," said the duchess, shaking her head; "and women rule\r
+the world. I assure you we can't bear mediocrities. We women, as some\r
+one says, love with our ears, just as you men love with your eyes, if\r
+you ever love at all."\r
+\r
+"It seems to me that we never do anything else," murmured Dorian.\r
+\r
+"Ah! then, you never really love, Mr. Gray," answered the duchess with\r
+mock sadness.\r
+\r
+"My dear Gladys!" cried Lord Henry. "How can you say that? Romance\r
+lives by repetition, and repetition converts an appetite into an art.\r
+Besides, each time that one loves is the only time one has ever loved.\r
+Difference of object does not alter singleness of passion. It merely\r
+intensifies it. We can have in life but one great experience at best,\r
+and the secret of life is to reproduce that experience as often as\r
+possible."\r
+\r
+"Even when one has been wounded by it, Harry?" asked the duchess after\r
+a pause.\r
+\r
+"Especially when one has been wounded by it," answered Lord Henry.\r
+\r
+The duchess turned and looked at Dorian Gray with a curious expression\r
+in her eyes. "What do you say to that, Mr. Gray?" she inquired.\r
+\r
+Dorian hesitated for a moment. Then he threw his head back and\r
+laughed. "I always agree with Harry, Duchess."\r
+\r
+"Even when he is wrong?"\r
+\r
+"Harry is never wrong, Duchess."\r
+\r
+"And does his philosophy make you happy?"\r
+\r
+"I have never searched for happiness. Who wants happiness? I have\r
+searched for pleasure."\r
+\r
+"And found it, Mr. Gray?"\r
+\r
+"Often. Too often."\r
+\r
+The duchess sighed. "I am searching for peace," she said, "and if I\r
+don't go and dress, I shall have none this evening."\r
+\r
+"Let me get you some orchids, Duchess," cried Dorian, starting to his\r
+feet and walking down the conservatory.\r
+\r
+"You are flirting disgracefully with him," said Lord Henry to his\r
+cousin. "You had better take care. He is very fascinating."\r
+\r
+"If he were not, there would be no battle."\r
+\r
+"Greek meets Greek, then?"\r
+\r
+"I am on the side of the Trojans. They fought for a woman."\r
+\r
+"They were defeated."\r
+\r
+"There are worse things than capture," she answered.\r
+\r
+"You gallop with a loose rein."\r
+\r
+"Pace gives life," was the _riposte_.\r
+\r
+"I shall write it in my diary to-night."\r
+\r
+"What?"\r
+\r
+"That a burnt child loves the fire."\r
+\r
+"I am not even singed. My wings are untouched."\r
+\r
+"You use them for everything, except flight."\r
+\r
+"Courage has passed from men to women. It is a new experience for us."\r
+\r
+"You have a rival."\r
+\r
+"Who?"\r
+\r
+He laughed. "Lady Narborough," he whispered. "She perfectly adores\r
+him."\r
+\r
+"You fill me with apprehension. The appeal to antiquity is fatal to us\r
+who are romanticists."\r
+\r
+"Romanticists! You have all the methods of science."\r
+\r
+"Men have educated us."\r
+\r
+"But not explained you."\r
+\r
+"Describe us as a sex," was her challenge.\r
+\r
+"Sphinxes without secrets."\r
+\r
+She looked at him, smiling. "How long Mr. Gray is!" she said. "Let us\r
+go and help him. I have not yet told him the colour of my frock."\r
+\r
+"Ah! you must suit your frock to his flowers, Gladys."\r
+\r
+"That would be a premature surrender."\r
+\r
+"Romantic art begins with its climax."\r
+\r
+"I must keep an opportunity for retreat."\r
+\r
+"In the Parthian manner?"\r
+\r
+"They found safety in the desert. I could not do that."\r
+\r
+"Women are not always allowed a choice," he answered, but hardly had he\r
+finished the sentence before from the far end of the conservatory came\r
+a stifled groan, followed by the dull sound of a heavy fall. Everybody\r
+started up. The duchess stood motionless in horror. And with fear in\r
+his eyes, Lord Henry rushed through the flapping palms to find Dorian\r
+Gray lying face downwards on the tiled floor in a deathlike swoon.\r
+\r
+He was carried at once into the blue drawing-room and laid upon one of\r
+the sofas. After a short time, he came to himself and looked round\r
+with a dazed expression.\r
+\r
+"What has happened?" he asked. "Oh! I remember. Am I safe here,\r
+Harry?" He began to tremble.\r
+\r
+"My dear Dorian," answered Lord Henry, "you merely fainted. That was\r
+all. You must have overtired yourself. You had better not come down\r
+to dinner. I will take your place."\r
+\r
+"No, I will come down," he said, struggling to his feet. "I would\r
+rather come down. I must not be alone."\r
+\r
+He went to his room and dressed. There was a wild recklessness of\r
+gaiety in his manner as he sat at table, but now and then a thrill of\r
+terror ran through him when he remembered that, pressed against the\r
+window of the conservatory, like a white handkerchief, he had seen the\r
+face of James Vane watching him.\r
+\r
+\r
+\r
+CHAPTER 18\r
+\r
+The next day he did not leave the house, and, indeed, spent most of the\r
+time in his own room, sick with a wild terror of dying, and yet\r
+indifferent to life itself. The consciousness of being hunted, snared,\r
+tracked down, had begun to dominate him. If the tapestry did but\r
+tremble in the wind, he shook. The dead leaves that were blown against\r
+the leaded panes seemed to him like his own wasted resolutions and wild\r
+regrets. When he closed his eyes, he saw again the sailor's face\r
+peering through the mist-stained glass, and horror seemed once more to\r
+lay its hand upon his heart.\r
+\r
+But perhaps it had been only his fancy that had called vengeance out of\r
+the night and set the hideous shapes of punishment before him. Actual\r
+life was chaos, but there was something terribly logical in the\r
+imagination. It was the imagination that set remorse to dog the feet\r
+of sin. It was the imagination that made each crime bear its misshapen\r
+brood. In the common world of fact the wicked were not punished, nor\r
+the good rewarded. Success was given to the strong, failure thrust\r
+upon the weak. That was all. Besides, had any stranger been prowling\r
+round the house, he would have been seen by the servants or the\r
+keepers. Had any foot-marks been found on the flower-beds, the\r
+gardeners would have reported it. Yes, it had been merely fancy.\r
+Sibyl Vane's brother had not come back to kill him. He had sailed away\r
+in his ship to founder in some winter sea. From him, at any rate, he\r
+was safe. Why, the man did not know who he was, could not know who he\r
+was. The mask of youth had saved him.\r
+\r
+And yet if it had been merely an illusion, how terrible it was to think\r
+that conscience could raise such fearful phantoms, and give them\r
+visible form, and make them move before one! What sort of life would\r
+his be if, day and night, shadows of his crime were to peer at him from\r
+silent corners, to mock him from secret places, to whisper in his ear\r
+as he sat at the feast, to wake him with icy fingers as he lay asleep!\r
+As the thought crept through his brain, he grew pale with terror, and\r
+the air seemed to him to have become suddenly colder. Oh! in what a\r
+wild hour of madness he had killed his friend! How ghastly the mere\r
+memory of the scene! He saw it all again. Each hideous detail came\r
+back to him with added horror. Out of the black cave of time, terrible\r
+and swathed in scarlet, rose the image of his sin. When Lord Henry\r
+came in at six o'clock, he found him crying as one whose heart will\r
+break.\r
+\r
+It was not till the third day that he ventured to go out. There was\r
+something in the clear, pine-scented air of that winter morning that\r
+seemed to bring him back his joyousness and his ardour for life. But\r
+it was not merely the physical conditions of environment that had\r
+caused the change. His own nature had revolted against the excess of\r
+anguish that had sought to maim and mar the perfection of its calm.\r
+With subtle and finely wrought temperaments it is always so. Their\r
+strong passions must either bruise or bend. They either slay the man,\r
+or themselves die. Shallow sorrows and shallow loves live on. The\r
+loves and sorrows that are great are destroyed by their own plenitude.\r
+Besides, he had convinced himself that he had been the victim of a\r
+terror-stricken imagination, and looked back now on his fears with\r
+something of pity and not a little of contempt.\r
+\r
+After breakfast, he walked with the duchess for an hour in the garden\r
+and then drove across the park to join the shooting-party. The crisp\r
+frost lay like salt upon the grass. The sky was an inverted cup of\r
+blue metal. A thin film of ice bordered the flat, reed-grown lake.\r
+\r
+At the corner of the pine-wood he caught sight of Sir Geoffrey\r
+Clouston, the duchess's brother, jerking two spent cartridges out of\r
+his gun. He jumped from the cart, and having told the groom to take\r
+the mare home, made his way towards his guest through the withered\r
+bracken and rough undergrowth.\r
+\r
+"Have you had good sport, Geoffrey?" he asked.\r
+\r
+"Not very good, Dorian. I think most of the birds have gone to the\r
+open. I dare say it will be better after lunch, when we get to new\r
+ground."\r
+\r
+Dorian strolled along by his side. The keen aromatic air, the brown\r
+and red lights that glimmered in the wood, the hoarse cries of the\r
+beaters ringing out from time to time, and the sharp snaps of the guns\r
+that followed, fascinated him and filled him with a sense of delightful\r
+freedom. He was dominated by the carelessness of happiness, by the\r
+high indifference of joy.\r
+\r
+Suddenly from a lumpy tussock of old grass some twenty yards in front\r
+of them, with black-tipped ears erect and long hinder limbs throwing it\r
+forward, started a hare. It bolted for a thicket of alders. Sir\r
+Geoffrey put his gun to his shoulder, but there was something in the\r
+animal's grace of movement that strangely charmed Dorian Gray, and he\r
+cried out at once, "Don't shoot it, Geoffrey. Let it live."\r
+\r
+"What nonsense, Dorian!" laughed his companion, and as the hare bounded\r
+into the thicket, he fired. There were two cries heard, the cry of a\r
+hare in pain, which is dreadful, the cry of a man in agony, which is\r
+worse.\r
+\r
+"Good heavens! I have hit a beater!" exclaimed Sir Geoffrey. "What an\r
+ass the man was to get in front of the guns! Stop shooting there!" he\r
+called out at the top of his voice. "A man is hurt."\r
+\r
+The head-keeper came running up with a stick in his hand.\r
+\r
+"Where, sir? Where is he?" he shouted. At the same time, the firing\r
+ceased along the line.\r
+\r
+"Here," answered Sir Geoffrey angrily, hurrying towards the thicket.\r
+"Why on earth don't you keep your men back? Spoiled my shooting for\r
+the day."\r
+\r
+Dorian watched them as they plunged into the alder-clump, brushing the\r
+lithe swinging branches aside. In a few moments they emerged, dragging\r
+a body after them into the sunlight. He turned away in horror. It\r
+seemed to him that misfortune followed wherever he went. He heard Sir\r
+Geoffrey ask if the man was really dead, and the affirmative answer of\r
+the keeper. The wood seemed to him to have become suddenly alive with\r
+faces. There was the trampling of myriad feet and the low buzz of\r
+voices. A great copper-breasted pheasant came beating through the\r
+boughs overhead.\r
+\r
+After a few moments--that were to him, in his perturbed state, like\r
+endless hours of pain--he felt a hand laid on his shoulder. He started\r
+and looked round.\r
+\r
+"Dorian," said Lord Henry, "I had better tell them that the shooting is\r
+stopped for to-day. It would not look well to go on."\r
+\r
+"I wish it were stopped for ever, Harry," he answered bitterly. "The\r
+whole thing is hideous and cruel. Is the man ...?"\r
+\r
+He could not finish the sentence.\r
+\r
+"I am afraid so," rejoined Lord Henry. "He got the whole charge of\r
+shot in his chest. He must have died almost instantaneously. Come;\r
+let us go home."\r
+\r
+They walked side by side in the direction of the avenue for nearly\r
+fifty yards without speaking. Then Dorian looked at Lord Henry and\r
+said, with a heavy sigh, "It is a bad omen, Harry, a very bad omen."\r
+\r
+"What is?" asked Lord Henry. "Oh! this accident, I suppose. My dear\r
+fellow, it can't be helped. It was the man's own fault. Why did he\r
+get in front of the guns? Besides, it is nothing to us. It is rather\r
+awkward for Geoffrey, of course. It does not do to pepper beaters. It\r
+makes people think that one is a wild shot. And Geoffrey is not; he\r
+shoots very straight. But there is no use talking about the matter."\r
+\r
+Dorian shook his head. "It is a bad omen, Harry. I feel as if\r
+something horrible were going to happen to some of us. To myself,\r
+perhaps," he added, passing his hand over his eyes, with a gesture of\r
+pain.\r
+\r
+The elder man laughed. "The only horrible thing in the world is _ennui_,\r
+Dorian. That is the one sin for which there is no forgiveness. But we\r
+are not likely to suffer from it unless these fellows keep chattering\r
+about this thing at dinner. I must tell them that the subject is to be\r
+tabooed. As for omens, there is no such thing as an omen. Destiny\r
+does not send us heralds. She is too wise or too cruel for that.\r
+Besides, what on earth could happen to you, Dorian? You have\r
+everything in the world that a man can want. There is no one who would\r
+not be delighted to change places with you."\r
+\r
+"There is no one with whom I would not change places, Harry. Don't\r
+laugh like that. I am telling you the truth. The wretched peasant who\r
+has just died is better off than I am. I have no terror of death. It\r
+is the coming of death that terrifies me. Its monstrous wings seem to\r
+wheel in the leaden air around me. Good heavens! don't you see a man\r
+moving behind the trees there, watching me, waiting for me?"\r
+\r
+Lord Henry looked in the direction in which the trembling gloved hand\r
+was pointing. "Yes," he said, smiling, "I see the gardener waiting for\r
+you. I suppose he wants to ask you what flowers you wish to have on\r
+the table to-night. How absurdly nervous you are, my dear fellow! You\r
+must come and see my doctor, when we get back to town."\r
+\r
+Dorian heaved a sigh of relief as he saw the gardener approaching. The\r
+man touched his hat, glanced for a moment at Lord Henry in a hesitating\r
+manner, and then produced a letter, which he handed to his master.\r
+"Her Grace told me to wait for an answer," he murmured.\r
+\r
+Dorian put the letter into his pocket. "Tell her Grace that I am\r
+coming in," he said, coldly. The man turned round and went rapidly in\r
+the direction of the house.\r
+\r
+"How fond women are of doing dangerous things!" laughed Lord Henry.\r
+"It is one of the qualities in them that I admire most. A woman will\r
+flirt with anybody in the world as long as other people are looking on."\r
+\r
+"How fond you are of saying dangerous things, Harry! In the present\r
+instance, you are quite astray. I like the duchess very much, but I\r
+don't love her."\r
+\r
+"And the duchess loves you very much, but she likes you less, so you\r
+are excellently matched."\r
+\r
+"You are talking scandal, Harry, and there is never any basis for\r
+scandal."\r
+\r
+"The basis of every scandal is an immoral certainty," said Lord Henry,\r
+lighting a cigarette.\r
+\r
+"You would sacrifice anybody, Harry, for the sake of an epigram."\r
+\r
+"The world goes to the altar of its own accord," was the answer.\r
+\r
+"I wish I could love," cried Dorian Gray with a deep note of pathos in\r
+his voice. "But I seem to have lost the passion and forgotten the\r
+desire. I am too much concentrated on myself. My own personality has\r
+become a burden to me. I want to escape, to go away, to forget. It\r
+was silly of me to come down here at all. I think I shall send a wire\r
+to Harvey to have the yacht got ready. On a yacht one is safe."\r
+\r
+"Safe from what, Dorian? You are in some trouble. Why not tell me\r
+what it is? You know I would help you."\r
+\r
+"I can't tell you, Harry," he answered sadly. "And I dare say it is\r
+only a fancy of mine. This unfortunate accident has upset me. I have\r
+a horrible presentiment that something of the kind may happen to me."\r
+\r
+"What nonsense!"\r
+\r
+"I hope it is, but I can't help feeling it. Ah! here is the duchess,\r
+looking like Artemis in a tailor-made gown. You see we have come back,\r
+Duchess."\r
+\r
+"I have heard all about it, Mr. Gray," she answered. "Poor Geoffrey is\r
+terribly upset. And it seems that you asked him not to shoot the hare.\r
+How curious!"\r
+\r
+"Yes, it was very curious. I don't know what made me say it. Some\r
+whim, I suppose. It looked the loveliest of little live things. But I\r
+am sorry they told you about the man. It is a hideous subject."\r
+\r
+"It is an annoying subject," broke in Lord Henry. "It has no\r
+psychological value at all. Now if Geoffrey had done the thing on\r
+purpose, how interesting he would be! I should like to know some one\r
+who had committed a real murder."\r
+\r
+"How horrid of you, Harry!" cried the duchess. "Isn't it, Mr. Gray?\r
+Harry, Mr. Gray is ill again. He is going to faint."\r
+\r
+Dorian drew himself up with an effort and smiled. "It is nothing,\r
+Duchess," he murmured; "my nerves are dreadfully out of order. That is\r
+all. I am afraid I walked too far this morning. I didn't hear what\r
+Harry said. Was it very bad? You must tell me some other time. I\r
+think I must go and lie down. You will excuse me, won't you?"\r
+\r
+They had reached the great flight of steps that led from the\r
+conservatory on to the terrace. As the glass door closed behind\r
+Dorian, Lord Henry turned and looked at the duchess with his slumberous\r
+eyes. "Are you very much in love with him?" he asked.\r
+\r
+She did not answer for some time, but stood gazing at the landscape.\r
+"I wish I knew," she said at last.\r
+\r
+He shook his head. "Knowledge would be fatal. It is the uncertainty\r
+that charms one. A mist makes things wonderful."\r
+\r
+"One may lose one's way."\r
+\r
+"All ways end at the same point, my dear Gladys."\r
+\r
+"What is that?"\r
+\r
+"Disillusion."\r
+\r
+"It was my _debut_ in life," she sighed.\r
+\r
+"It came to you crowned."\r
+\r
+"I am tired of strawberry leaves."\r
+\r
+"They become you."\r
+\r
+"Only in public."\r
+\r
+"You would miss them," said Lord Henry.\r
+\r
+"I will not part with a petal."\r
+\r
+"Monmouth has ears."\r
+\r
+"Old age is dull of hearing."\r
+\r
+"Has he never been jealous?"\r
+\r
+"I wish he had been."\r
+\r
+He glanced about as if in search of something. "What are you looking\r
+for?" she inquired.\r
+\r
+"The button from your foil," he answered. "You have dropped it."\r
+\r
+She laughed. "I have still the mask."\r
+\r
+"It makes your eyes lovelier," was his reply.\r
+\r
+She laughed again. Her teeth showed like white seeds in a scarlet\r
+fruit.\r
+\r
+Upstairs, in his own room, Dorian Gray was lying on a sofa, with terror\r
+in every tingling fibre of his body. Life had suddenly become too\r
+hideous a burden for him to bear. The dreadful death of the unlucky\r
+beater, shot in the thicket like a wild animal, had seemed to him to\r
+pre-figure death for himself also. He had nearly swooned at what Lord\r
+Henry had said in a chance mood of cynical jesting.\r
+\r
+At five o'clock he rang his bell for his servant and gave him orders to\r
+pack his things for the night-express to town, and to have the brougham\r
+at the door by eight-thirty. He was determined not to sleep another\r
+night at Selby Royal. It was an ill-omened place. Death walked there\r
+in the sunlight. The grass of the forest had been spotted with blood.\r
+\r
+Then he wrote a note to Lord Henry, telling him that he was going up to\r
+town to consult his doctor and asking him to entertain his guests in\r
+his absence. As he was putting it into the envelope, a knock came to\r
+the door, and his valet informed him that the head-keeper wished to see\r
+him. He frowned and bit his lip. "Send him in," he muttered, after\r
+some moments' hesitation.\r
+\r
+As soon as the man entered, Dorian pulled his chequebook out of a\r
+drawer and spread it out before him.\r
+\r
+"I suppose you have come about the unfortunate accident of this\r
+morning, Thornton?" he said, taking up a pen.\r
+\r
+"Yes, sir," answered the gamekeeper.\r
+\r
+"Was the poor fellow married? Had he any people dependent on him?"\r
+asked Dorian, looking bored. "If so, I should not like them to be left\r
+in want, and will send them any sum of money you may think necessary."\r
+\r
+"We don't know who he is, sir. That is what I took the liberty of\r
+coming to you about."\r
+\r
+"Don't know who he is?" said Dorian, listlessly. "What do you mean?\r
+Wasn't he one of your men?"\r
+\r
+"No, sir. Never saw him before. Seems like a sailor, sir."\r
+\r
+The pen dropped from Dorian Gray's hand, and he felt as if his heart\r
+had suddenly stopped beating. "A sailor?" he cried out. "Did you say\r
+a sailor?"\r
+\r
+"Yes, sir. He looks as if he had been a sort of sailor; tattooed on\r
+both arms, and that kind of thing."\r
+\r
+"Was there anything found on him?" said Dorian, leaning forward and\r
+looking at the man with startled eyes. "Anything that would tell his\r
+name?"\r
+\r
+"Some money, sir--not much, and a six-shooter. There was no name of any\r
+kind. A decent-looking man, sir, but rough-like. A sort of sailor we\r
+think."\r
+\r
+Dorian started to his feet. A terrible hope fluttered past him. He\r
+clutched at it madly. "Where is the body?" he exclaimed. "Quick! I\r
+must see it at once."\r
+\r
+"It is in an empty stable in the Home Farm, sir. The folk don't like\r
+to have that sort of thing in their houses. They say a corpse brings\r
+bad luck."\r
+\r
+"The Home Farm! Go there at once and meet me. Tell one of the grooms\r
+to bring my horse round. No. Never mind. I'll go to the stables\r
+myself. It will save time."\r
+\r
+In less than a quarter of an hour, Dorian Gray was galloping down the\r
+long avenue as hard as he could go. The trees seemed to sweep past him\r
+in spectral procession, and wild shadows to fling themselves across his\r
+path. Once the mare swerved at a white gate-post and nearly threw him.\r
+He lashed her across the neck with his crop. She cleft the dusky air\r
+like an arrow. The stones flew from her hoofs.\r
+\r
+At last he reached the Home Farm. Two men were loitering in the yard.\r
+He leaped from the saddle and threw the reins to one of them. In the\r
+farthest stable a light was glimmering. Something seemed to tell him\r
+that the body was there, and he hurried to the door and put his hand\r
+upon the latch.\r
+\r
+There he paused for a moment, feeling that he was on the brink of a\r
+discovery that would either make or mar his life. Then he thrust the\r
+door open and entered.\r
+\r
+On a heap of sacking in the far corner was lying the dead body of a man\r
+dressed in a coarse shirt and a pair of blue trousers. A spotted\r
+handkerchief had been placed over the face. A coarse candle, stuck in\r
+a bottle, sputtered beside it.\r
+\r
+Dorian Gray shuddered. He felt that his could not be the hand to take\r
+the handkerchief away, and called out to one of the farm-servants to\r
+come to him.\r
+\r
+"Take that thing off the face. I wish to see it," he said, clutching\r
+at the door-post for support.\r
+\r
+When the farm-servant had done so, he stepped forward. A cry of joy\r
+broke from his lips. The man who had been shot in the thicket was\r
+James Vane.\r
+\r
+He stood there for some minutes looking at the dead body. As he rode\r
+home, his eyes were full of tears, for he knew he was safe.\r
+\r
+\r
+\r
+CHAPTER 19\r
+\r
+"There is no use your telling me that you are going to be good," cried\r
+Lord Henry, dipping his white fingers into a red copper bowl filled\r
+with rose-water. "You are quite perfect. Pray, don't change."\r
+\r
+Dorian Gray shook his head. "No, Harry, I have done too many dreadful\r
+things in my life. I am not going to do any more. I began my good\r
+actions yesterday."\r
+\r
+"Where were you yesterday?"\r
+\r
+"In the country, Harry. I was staying at a little inn by myself."\r
+\r
+"My dear boy," said Lord Henry, smiling, "anybody can be good in the\r
+country. There are no temptations there. That is the reason why\r
+people who live out of town are so absolutely uncivilized.\r
+Civilization is not by any means an easy thing to attain to. There are\r
+only two ways by which man can reach it. One is by being cultured, the\r
+other by being corrupt. Country people have no opportunity of being\r
+either, so they stagnate."\r
+\r
+"Culture and corruption," echoed Dorian. "I have known something of\r
+both. It seems terrible to me now that they should ever be found\r
+together. For I have a new ideal, Harry. I am going to alter. I\r
+think I have altered."\r
+\r
+"You have not yet told me what your good action was. Or did you say\r
+you had done more than one?" asked his companion as he spilled into his\r
+plate a little crimson pyramid of seeded strawberries and, through a\r
+perforated, shell-shaped spoon, snowed white sugar upon them.\r
+\r
+"I can tell you, Harry. It is not a story I could tell to any one\r
+else. I spared somebody. It sounds vain, but you understand what I\r
+mean. She was quite beautiful and wonderfully like Sibyl Vane. I\r
+think it was that which first attracted me to her. You remember Sibyl,\r
+don't you? How long ago that seems! Well, Hetty was not one of our\r
+own class, of course. She was simply a girl in a village. But I\r
+really loved her. I am quite sure that I loved her. All during this\r
+wonderful May that we have been having, I used to run down and see her\r
+two or three times a week. Yesterday she met me in a little orchard.\r
+The apple-blossoms kept tumbling down on her hair, and she was\r
+laughing. We were to have gone away together this morning at dawn.\r
+Suddenly I determined to leave her as flowerlike as I had found her."\r
+\r
+"I should think the novelty of the emotion must have given you a thrill\r
+of real pleasure, Dorian," interrupted Lord Henry. "But I can finish\r
+your idyll for you. You gave her good advice and broke her heart.\r
+That was the beginning of your reformation."\r
+\r
+"Harry, you are horrible! You mustn't say these dreadful things.\r
+Hetty's heart is not broken. Of course, she cried and all that. But\r
+there is no disgrace upon her. She can live, like Perdita, in her\r
+garden of mint and marigold."\r
+\r
+"And weep over a faithless Florizel," said Lord Henry, laughing, as he\r
+leaned back in his chair. "My dear Dorian, you have the most curiously\r
+boyish moods. Do you think this girl will ever be really content now\r
+with any one of her own rank? I suppose she will be married some day\r
+to a rough carter or a grinning ploughman. Well, the fact of having\r
+met you, and loved you, will teach her to despise her husband, and she\r
+will be wretched. From a moral point of view, I cannot say that I\r
+think much of your great renunciation. Even as a beginning, it is\r
+poor. Besides, how do you know that Hetty isn't floating at the\r
+present moment in some starlit mill-pond, with lovely water-lilies\r
+round her, like Ophelia?"\r
+\r
+"I can't bear this, Harry! You mock at everything, and then suggest\r
+the most serious tragedies. I am sorry I told you now. I don't care\r
+what you say to me. I know I was right in acting as I did. Poor\r
+Hetty! As I rode past the farm this morning, I saw her white face at\r
+the window, like a spray of jasmine. Don't let us talk about it any\r
+more, and don't try to persuade me that the first good action I have\r
+done for years, the first little bit of self-sacrifice I have ever\r
+known, is really a sort of sin. I want to be better. I am going to be\r
+better. Tell me something about yourself. What is going on in town?\r
+I have not been to the club for days."\r
+\r
+"The people are still discussing poor Basil's disappearance."\r
+\r
+"I should have thought they had got tired of that by this time," said\r
+Dorian, pouring himself out some wine and frowning slightly.\r
+\r
+"My dear boy, they have only been talking about it for six weeks, and\r
+the British public are really not equal to the mental strain of having\r
+more than one topic every three months. They have been very fortunate\r
+lately, however. They have had my own divorce-case and Alan Campbell's\r
+suicide. Now they have got the mysterious disappearance of an artist.\r
+Scotland Yard still insists that the man in the grey ulster who left\r
+for Paris by the midnight train on the ninth of November was poor\r
+Basil, and the French police declare that Basil never arrived in Paris\r
+at all. I suppose in about a fortnight we shall be told that he has\r
+been seen in San Francisco. It is an odd thing, but every one who\r
+disappears is said to be seen at San Francisco. It must be a\r
+delightful city, and possess all the attractions of the next world."\r
+\r
+"What do you think has happened to Basil?" asked Dorian, holding up his\r
+Burgundy against the light and wondering how it was that he could\r
+discuss the matter so calmly.\r
+\r
+"I have not the slightest idea. If Basil chooses to hide himself, it\r
+is no business of mine. If he is dead, I don't want to think about\r
+him. Death is the only thing that ever terrifies me. I hate it."\r
+\r
+"Why?" said the younger man wearily.\r
+\r
+"Because," said Lord Henry, passing beneath his nostrils the gilt\r
+trellis of an open vinaigrette box, "one can survive everything\r
+nowadays except that. Death and vulgarity are the only two facts in\r
+the nineteenth century that one cannot explain away. Let us have our\r
+coffee in the music-room, Dorian. You must play Chopin to me. The man\r
+with whom my wife ran away played Chopin exquisitely. Poor Victoria!\r
+I was very fond of her. The house is rather lonely without her. Of\r
+course, married life is merely a habit, a bad habit. But then one\r
+regrets the loss even of one's worst habits. Perhaps one regrets them\r
+the most. They are such an essential part of one's personality."\r
+\r
+Dorian said nothing, but rose from the table, and passing into the next\r
+room, sat down to the piano and let his fingers stray across the white\r
+and black ivory of the keys. After the coffee had been brought in, he\r
+stopped, and looking over at Lord Henry, said, "Harry, did it ever\r
+occur to you that Basil was murdered?"\r
+\r
+Lord Henry yawned. "Basil was very popular, and always wore a\r
+Waterbury watch. Why should he have been murdered? He was not clever\r
+enough to have enemies. Of course, he had a wonderful genius for\r
+painting. But a man can paint like Velasquez and yet be as dull as\r
+possible. Basil was really rather dull. He only interested me once,\r
+and that was when he told me, years ago, that he had a wild adoration\r
+for you and that you were the dominant motive of his art."\r
+\r
+"I was very fond of Basil," said Dorian with a note of sadness in his\r
+voice. "But don't people say that he was murdered?"\r
+\r
+"Oh, some of the papers do. It does not seem to me to be at all\r
+probable. I know there are dreadful places in Paris, but Basil was not\r
+the sort of man to have gone to them. He had no curiosity. It was his\r
+chief defect."\r
+\r
+"What would you say, Harry, if I told you that I had murdered Basil?"\r
+said the younger man. He watched him intently after he had spoken.\r
+\r
+"I would say, my dear fellow, that you were posing for a character that\r
+doesn't suit you. All crime is vulgar, just as all vulgarity is crime.\r
+It is not in you, Dorian, to commit a murder. I am sorry if I hurt\r
+your vanity by saying so, but I assure you it is true. Crime belongs\r
+exclusively to the lower orders. I don't blame them in the smallest\r
+degree. I should fancy that crime was to them what art is to us,\r
+simply a method of procuring extraordinary sensations."\r
+\r
+"A method of procuring sensations? Do you think, then, that a man who\r
+has once committed a murder could possibly do the same crime again?\r
+Don't tell me that."\r
+\r
+"Oh! anything becomes a pleasure if one does it too often," cried Lord\r
+Henry, laughing. "That is one of the most important secrets of life.\r
+I should fancy, however, that murder is always a mistake. One should\r
+never do anything that one cannot talk about after dinner. But let us\r
+pass from poor Basil. I wish I could believe that he had come to such\r
+a really romantic end as you suggest, but I can't. I dare say he fell\r
+into the Seine off an omnibus and that the conductor hushed up the\r
+scandal. Yes: I should fancy that was his end. I see him lying now\r
+on his back under those dull-green waters, with the heavy barges\r
+floating over him and long weeds catching in his hair. Do you know, I\r
+don't think he would have done much more good work. During the last\r
+ten years his painting had gone off very much."\r
+\r
+Dorian heaved a sigh, and Lord Henry strolled across the room and began\r
+to stroke the head of a curious Java parrot, a large, grey-plumaged\r
+bird with pink crest and tail, that was balancing itself upon a bamboo\r
+perch. As his pointed fingers touched it, it dropped the white scurf\r
+of crinkled lids over black, glasslike eyes and began to sway backwards\r
+and forwards.\r
+\r
+"Yes," he continued, turning round and taking his handkerchief out of\r
+his pocket; "his painting had quite gone off. It seemed to me to have\r
+lost something. It had lost an ideal. When you and he ceased to be\r
+great friends, he ceased to be a great artist. What was it separated\r
+you? I suppose he bored you. If so, he never forgave you. It's a\r
+habit bores have. By the way, what has become of that wonderful\r
+portrait he did of you? I don't think I have ever seen it since he\r
+finished it. Oh! I remember your telling me years ago that you had\r
+sent it down to Selby, and that it had got mislaid or stolen on the\r
+way. You never got it back? What a pity! it was really a\r
+masterpiece. I remember I wanted to buy it. I wish I had now. It\r
+belonged to Basil's best period. Since then, his work was that curious\r
+mixture of bad painting and good intentions that always entitles a man\r
+to be called a representative British artist. Did you advertise for\r
+it? You should."\r
+\r
+"I forget," said Dorian. "I suppose I did. But I never really liked\r
+it. I am sorry I sat for it. The memory of the thing is hateful to\r
+me. Why do you talk of it? It used to remind me of those curious\r
+lines in some play--Hamlet, I think--how do they run?--\r
+\r
+ "Like the painting of a sorrow,\r
+ A face without a heart."\r
+\r
+Yes: that is what it was like."\r
+\r
+Lord Henry laughed. "If a man treats life artistically, his brain is\r
+his heart," he answered, sinking into an arm-chair.\r
+\r
+Dorian Gray shook his head and struck some soft chords on the piano.\r
+"'Like the painting of a sorrow,'" he repeated, "'a face without a\r
+heart.'"\r
+\r
+The elder man lay back and looked at him with half-closed eyes. "By\r
+the way, Dorian," he said after a pause, "'what does it profit a man if\r
+he gain the whole world and lose--how does the quotation run?--his own\r
+soul'?"\r
+\r
+The music jarred, and Dorian Gray started and stared at his friend.\r
+"Why do you ask me that, Harry?"\r
+\r
+"My dear fellow," said Lord Henry, elevating his eyebrows in surprise,\r
+"I asked you because I thought you might be able to give me an answer.\r
+That is all. I was going through the park last Sunday, and close by\r
+the Marble Arch there stood a little crowd of shabby-looking people\r
+listening to some vulgar street-preacher. As I passed by, I heard the\r
+man yelling out that question to his audience. It struck me as being\r
+rather dramatic. London is very rich in curious effects of that kind.\r
+A wet Sunday, an uncouth Christian in a mackintosh, a ring of sickly\r
+white faces under a broken roof of dripping umbrellas, and a wonderful\r
+phrase flung into the air by shrill hysterical lips--it was really very\r
+good in its way, quite a suggestion. I thought of telling the prophet\r
+that art had a soul, but that man had not. I am afraid, however, he\r
+would not have understood me."\r
+\r
+"Don't, Harry. The soul is a terrible reality. It can be bought, and\r
+sold, and bartered away. It can be poisoned, or made perfect. There\r
+is a soul in each one of us. I know it."\r
+\r
+"Do you feel quite sure of that, Dorian?"\r
+\r
+"Quite sure."\r
+\r
+"Ah! then it must be an illusion. The things one feels absolutely\r
+certain about are never true. That is the fatality of faith, and the\r
+lesson of romance. How grave you are! Don't be so serious. What have\r
+you or I to do with the superstitions of our age? No: we have given\r
+up our belief in the soul. Play me something. Play me a nocturne,\r
+Dorian, and, as you play, tell me, in a low voice, how you have kept\r
+your youth. You must have some secret. I am only ten years older than\r
+you are, and I am wrinkled, and worn, and yellow. You are really\r
+wonderful, Dorian. You have never looked more charming than you do\r
+to-night. You remind me of the day I saw you first. You were rather\r
+cheeky, very shy, and absolutely extraordinary. You have changed, of\r
+course, but not in appearance. I wish you would tell me your secret.\r
+To get back my youth I would do anything in the world, except take\r
+exercise, get up early, or be respectable. Youth! There is nothing\r
+like it. It's absurd to talk of the ignorance of youth. The only\r
+people to whose opinions I listen now with any respect are people much\r
+younger than myself. They seem in front of me. Life has revealed to\r
+them her latest wonder. As for the aged, I always contradict the aged.\r
+I do it on principle. If you ask them their opinion on something that\r
+happened yesterday, they solemnly give you the opinions current in\r
+1820, when people wore high stocks, believed in everything, and knew\r
+absolutely nothing. How lovely that thing you are playing is! I\r
+wonder, did Chopin write it at Majorca, with the sea weeping round the\r
+villa and the salt spray dashing against the panes? It is marvellously\r
+romantic. What a blessing it is that there is one art left to us that\r
+is not imitative! Don't stop. I want music to-night. It seems to me\r
+that you are the young Apollo and that I am Marsyas listening to you.\r
+I have sorrows, Dorian, of my own, that even you know nothing of. The\r
+tragedy of old age is not that one is old, but that one is young. I am\r
+amazed sometimes at my own sincerity. Ah, Dorian, how happy you are!\r
+What an exquisite life you have had! You have drunk deeply of\r
+everything. You have crushed the grapes against your palate. Nothing\r
+has been hidden from you. And it has all been to you no more than the\r
+sound of music. It has not marred you. You are still the same."\r
+\r
+"I am not the same, Harry."\r
+\r
+"Yes, you are the same. I wonder what the rest of your life will be.\r
+Don't spoil it by renunciations. At present you are a perfect type.\r
+Don't make yourself incomplete. You are quite flawless now. You need\r
+not shake your head: you know you are. Besides, Dorian, don't deceive\r
+yourself. Life is not governed by will or intention. Life is a\r
+question of nerves, and fibres, and slowly built-up cells in which\r
+thought hides itself and passion has its dreams. You may fancy\r
+yourself safe and think yourself strong. But a chance tone of colour\r
+in a room or a morning sky, a particular perfume that you had once\r
+loved and that brings subtle memories with it, a line from a forgotten\r
+poem that you had come across again, a cadence from a piece of music\r
+that you had ceased to play--I tell you, Dorian, that it is on things\r
+like these that our lives depend. Browning writes about that\r
+somewhere; but our own senses will imagine them for us. There are\r
+moments when the odour of _lilas blanc_ passes suddenly across me, and I\r
+have to live the strangest month of my life over again. I wish I could\r
+change places with you, Dorian. The world has cried out against us\r
+both, but it has always worshipped you. It always will worship you.\r
+You are the type of what the age is searching for, and what it is\r
+afraid it has found. I am so glad that you have never done anything,\r
+never carved a statue, or painted a picture, or produced anything\r
+outside of yourself! Life has been your art. You have set yourself to\r
+music. Your days are your sonnets."\r
+\r
+Dorian rose up from the piano and passed his hand through his hair.\r
+"Yes, life has been exquisite," he murmured, "but I am not going to\r
+have the same life, Harry. And you must not say these extravagant\r
+things to me. You don't know everything about me. I think that if you\r
+did, even you would turn from me. You laugh. Don't laugh."\r
+\r
+"Why have you stopped playing, Dorian? Go back and give me the\r
+nocturne over again. Look at that great, honey-coloured moon that\r
+hangs in the dusky air. She is waiting for you to charm her, and if\r
+you play she will come closer to the earth. You won't? Let us go to\r
+the club, then. It has been a charming evening, and we must end it\r
+charmingly. There is some one at White's who wants immensely to know\r
+you--young Lord Poole, Bournemouth's eldest son. He has already copied\r
+your neckties, and has begged me to introduce him to you. He is quite\r
+delightful and rather reminds me of you."\r
+\r
+"I hope not," said Dorian with a sad look in his eyes. "But I am tired\r
+to-night, Harry. I shan't go to the club. It is nearly eleven, and I\r
+want to go to bed early."\r
+\r
+"Do stay. You have never played so well as to-night. There was\r
+something in your touch that was wonderful. It had more expression\r
+than I had ever heard from it before."\r
+\r
+"It is because I am going to be good," he answered, smiling. "I am a\r
+little changed already."\r
+\r
+"You cannot change to me, Dorian," said Lord Henry. "You and I will\r
+always be friends."\r
+\r
+"Yet you poisoned me with a book once. I should not forgive that.\r
+Harry, promise me that you will never lend that book to any one. It\r
+does harm."\r
+\r
+"My dear boy, you are really beginning to moralize. You will soon be\r
+going about like the converted, and the revivalist, warning people\r
+against all the sins of which you have grown tired. You are much too\r
+delightful to do that. Besides, it is no use. You and I are what we\r
+are, and will be what we will be. As for being poisoned by a book,\r
+there is no such thing as that. Art has no influence upon action. It\r
+annihilates the desire to act. It is superbly sterile. The books that\r
+the world calls immoral are books that show the world its own shame.\r
+That is all. But we won't discuss literature. Come round to-morrow. I\r
+am going to ride at eleven. We might go together, and I will take you\r
+to lunch afterwards with Lady Branksome. She is a charming woman, and\r
+wants to consult you about some tapestries she is thinking of buying.\r
+Mind you come. Or shall we lunch with our little duchess? She says\r
+she never sees you now. Perhaps you are tired of Gladys? I thought\r
+you would be. Her clever tongue gets on one's nerves. Well, in any\r
+case, be here at eleven."\r
+\r
+"Must I really come, Harry?"\r
+\r
+"Certainly. The park is quite lovely now. I don't think there have\r
+been such lilacs since the year I met you."\r
+\r
+"Very well. I shall be here at eleven," said Dorian. "Good night,\r
+Harry." As he reached the door, he hesitated for a moment, as if he\r
+had something more to say. Then he sighed and went out.\r
+\r
+\r
+\r
+CHAPTER 20\r
+\r
+It was a lovely night, so warm that he threw his coat over his arm and\r
+did not even put his silk scarf round his throat. As he strolled home,\r
+smoking his cigarette, two young men in evening dress passed him. He\r
+heard one of them whisper to the other, "That is Dorian Gray." He\r
+remembered how pleased he used to be when he was pointed out, or stared\r
+at, or talked about. He was tired of hearing his own name now. Half\r
+the charm of the little village where he had been so often lately was\r
+that no one knew who he was. He had often told the girl whom he had\r
+lured to love him that he was poor, and she had believed him. He had\r
+told her once that he was wicked, and she had laughed at him and\r
+answered that wicked people were always very old and very ugly. What a\r
+laugh she had!--just like a thrush singing. And how pretty she had\r
+been in her cotton dresses and her large hats! She knew nothing, but\r
+she had everything that he had lost.\r
+\r
+When he reached home, he found his servant waiting up for him. He sent\r
+him to bed, and threw himself down on the sofa in the library, and\r
+began to think over some of the things that Lord Henry had said to him.\r
+\r
+Was it really true that one could never change? He felt a wild longing\r
+for the unstained purity of his boyhood--his rose-white boyhood, as\r
+Lord Henry had once called it. He knew that he had tarnished himself,\r
+filled his mind with corruption and given horror to his fancy; that he\r
+had been an evil influence to others, and had experienced a terrible\r
+joy in being so; and that of the lives that had crossed his own, it had\r
+been the fairest and the most full of promise that he had brought to\r
+shame. But was it all irretrievable? Was there no hope for him?\r
+\r
+Ah! in what a monstrous moment of pride and passion he had prayed that\r
+the portrait should bear the burden of his days, and he keep the\r
+unsullied splendour of eternal youth! All his failure had been due to\r
+that. Better for him that each sin of his life had brought its sure\r
+swift penalty along with it. There was purification in punishment.\r
+Not "Forgive us our sins" but "Smite us for our iniquities" should be\r
+the prayer of man to a most just God.\r
+\r
+The curiously carved mirror that Lord Henry had given to him, so many\r
+years ago now, was standing on the table, and the white-limbed Cupids\r
+laughed round it as of old. He took it up, as he had done on that\r
+night of horror when he had first noted the change in the fatal\r
+picture, and with wild, tear-dimmed eyes looked into its polished\r
+shield. Once, some one who had terribly loved him had written to him a\r
+mad letter, ending with these idolatrous words: "The world is changed\r
+because you are made of ivory and gold. The curves of your lips\r
+rewrite history." The phrases came back to his memory, and he repeated\r
+them over and over to himself. Then he loathed his own beauty, and\r
+flinging the mirror on the floor, crushed it into silver splinters\r
+beneath his heel. It was his beauty that had ruined him, his beauty\r
+and the youth that he had prayed for. But for those two things, his\r
+life might have been free from stain. His beauty had been to him but a\r
+mask, his youth but a mockery. What was youth at best? A green, an\r
+unripe time, a time of shallow moods, and sickly thoughts. Why had he\r
+worn its livery? Youth had spoiled him.\r
+\r
+It was better not to think of the past. Nothing could alter that. It\r
+was of himself, and of his own future, that he had to think. James\r
+Vane was hidden in a nameless grave in Selby churchyard. Alan Campbell\r
+had shot himself one night in his laboratory, but had not revealed the\r
+secret that he had been forced to know. The excitement, such as it\r
+was, over Basil Hallward's disappearance would soon pass away. It was\r
+already waning. He was perfectly safe there. Nor, indeed, was it the\r
+death of Basil Hallward that weighed most upon his mind. It was the\r
+living death of his own soul that troubled him. Basil had painted the\r
+portrait that had marred his life. He could not forgive him that. It\r
+was the portrait that had done everything. Basil had said things to\r
+him that were unbearable, and that he had yet borne with patience. The\r
+murder had been simply the madness of a moment. As for Alan Campbell,\r
+his suicide had been his own act. He had chosen to do it. It was\r
+nothing to him.\r
+\r
+A new life! That was what he wanted. That was what he was waiting\r
+for. Surely he had begun it already. He had spared one innocent\r
+thing, at any rate. He would never again tempt innocence. He would be\r
+good.\r
+\r
+As he thought of Hetty Merton, he began to wonder if the portrait in\r
+the locked room had changed. Surely it was not still so horrible as it\r
+had been? Perhaps if his life became pure, he would be able to expel\r
+every sign of evil passion from the face. Perhaps the signs of evil\r
+had already gone away. He would go and look.\r
+\r
+He took the lamp from the table and crept upstairs. As he unbarred the\r
+door, a smile of joy flitted across his strangely young-looking face\r
+and lingered for a moment about his lips. Yes, he would be good, and\r
+the hideous thing that he had hidden away would no longer be a terror\r
+to him. He felt as if the load had been lifted from him already.\r
+\r
+He went in quietly, locking the door behind him, as was his custom, and\r
+dragged the purple hanging from the portrait. A cry of pain and\r
+indignation broke from him. He could see no change, save that in the\r
+eyes there was a look of cunning and in the mouth the curved wrinkle of\r
+the hypocrite. The thing was still loathsome--more loathsome, if\r
+possible, than before--and the scarlet dew that spotted the hand seemed\r
+brighter, and more like blood newly spilled. Then he trembled. Had it\r
+been merely vanity that had made him do his one good deed? Or the\r
+desire for a new sensation, as Lord Henry had hinted, with his mocking\r
+laugh? Or that passion to act a part that sometimes makes us do things\r
+finer than we are ourselves? Or, perhaps, all these? And why was the\r
+red stain larger than it had been? It seemed to have crept like a\r
+horrible disease over the wrinkled fingers. There was blood on the\r
+painted feet, as though the thing had dripped--blood even on the hand\r
+that had not held the knife. Confess? Did it mean that he was to\r
+confess? To give himself up and be put to death? He laughed. He felt\r
+that the idea was monstrous. Besides, even if he did confess, who\r
+would believe him? There was no trace of the murdered man anywhere.\r
+Everything belonging to him had been destroyed. He himself had burned\r
+what had been below-stairs. The world would simply say that he was mad.\r
+They would shut him up if he persisted in his story.... Yet it was\r
+his duty to confess, to suffer public shame, and to make public\r
+atonement. There was a God who called upon men to tell their sins to\r
+earth as well as to heaven. Nothing that he could do would cleanse him\r
+till he had told his own sin. His sin? He shrugged his shoulders.\r
+The death of Basil Hallward seemed very little to him. He was thinking\r
+of Hetty Merton. For it was an unjust mirror, this mirror of his soul\r
+that he was looking at. Vanity? Curiosity? Hypocrisy? Had there\r
+been nothing more in his renunciation than that? There had been\r
+something more. At least he thought so. But who could tell? ... No.\r
+There had been nothing more. Through vanity he had spared her. In\r
+hypocrisy he had worn the mask of goodness. For curiosity's sake he\r
+had tried the denial of self. He recognized that now.\r
+\r
+But this murder--was it to dog him all his life? Was he always to be\r
+burdened by his past? Was he really to confess? Never. There was\r
+only one bit of evidence left against him. The picture itself--that\r
+was evidence. He would destroy it. Why had he kept it so long? Once\r
+it had given him pleasure to watch it changing and growing old. Of\r
+late he had felt no such pleasure. It had kept him awake at night.\r
+When he had been away, he had been filled with terror lest other eyes\r
+should look upon it. It had brought melancholy across his passions.\r
+Its mere memory had marred many moments of joy. It had been like\r
+conscience to him. Yes, it had been conscience. He would destroy it.\r
+\r
+He looked round and saw the knife that had stabbed Basil Hallward. He\r
+had cleaned it many times, till there was no stain left upon it. It\r
+was bright, and glistened. As it had killed the painter, so it would\r
+kill the painter's work, and all that that meant. It would kill the\r
+past, and when that was dead, he would be free. It would kill this\r
+monstrous soul-life, and without its hideous warnings, he would be at\r
+peace. He seized the thing, and stabbed the picture with it.\r
+\r
+There was a cry heard, and a crash. The cry was so horrible in its\r
+agony that the frightened servants woke and crept out of their rooms.\r
+Two gentlemen, who were passing in the square below, stopped and looked\r
+up at the great house. They walked on till they met a policeman and\r
+brought him back. The man rang the bell several times, but there was\r
+no answer. Except for a light in one of the top windows, the house was\r
+all dark. After a time, he went away and stood in an adjoining portico\r
+and watched.\r
+\r
+"Whose house is that, Constable?" asked the elder of the two gentlemen.\r
+\r
+"Mr. Dorian Gray's, sir," answered the policeman.\r
+\r
+They looked at each other, as they walked away, and sneered. One of\r
+them was Sir Henry Ashton's uncle.\r
+\r
+Inside, in the servants' part of the house, the half-clad domestics\r
+were talking in low whispers to each other. Old Mrs. Leaf was crying\r
+and wringing her hands. Francis was as pale as death.\r
+\r
+After about a quarter of an hour, he got the coachman and one of the\r
+footmen and crept upstairs. They knocked, but there was no reply.\r
+They called out. Everything was still. Finally, after vainly trying\r
+to force the door, they got on the roof and dropped down on to the\r
+balcony. The windows yielded easily--their bolts were old.\r
+\r
+When they entered, they found hanging upon the wall a splendid portrait\r
+of their master as they had last seen him, in all the wonder of his\r
+exquisite youth and beauty. Lying on the floor was a dead man, in\r
+evening dress, with a knife in his heart. He was withered, wrinkled,\r
+and loathsome of visage. It was not till they had examined the rings\r
+that they recognized who it was.\r

+\r
+1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the\r
+trademark owner, any agent or employee of the Foundation, anyone\r
+providing copies of Project Gutenberg-tm electronic works in accordance\r
+with this agreement, and any volunteers associated with the production,\r
+promotion and distribution of Project Gutenberg-tm electronic works,\r
+harmless from all liability, costs and expenses, including legal fees,\r
+that arise directly or indirectly from any of the following which you do\r
+or cause to occur: (a) distribution of this or any Project Gutenberg-tm\r
+work, (b) alteration, modification, or additions or deletions to any\r
+Project Gutenberg-tm work, and (c) any Defect you cause.\r
+\r
+\r
+Section 2. Information about the Mission of Project Gutenberg-tm\r
+\r
+Project Gutenberg-tm is synonymous with the free distribution of\r
+electronic works in formats readable by the widest variety of computers\r
+including obsolete, old, middle-aged and new computers. It exists\r
+because of the efforts of hundreds of volunteers and donations from\r
+people in all walks of life.\r
+\r
+Volunteers and financial support to provide volunteers with the\r
+assistance they need, is critical to reaching Project Gutenberg-tm's\r
+goals and ensuring that the Project Gutenberg-tm collection will\r
+remain freely available for generations to come. In 2001, the Project\r
+Gutenberg Literary Archive Foundation was created to provide a secure\r
+and permanent future for Project Gutenberg-tm and future generations.\r
+To learn more about the Project Gutenberg Literary Archive Foundation\r
+and how your efforts and donations can help, see Sections 3 and 4\r
+and the Foundation web page at http://www.pglaf.org.\r
+\r
+\r
+Section 3. Information about the Project Gutenberg Literary Archive\r
+Foundation\r
+\r
+The Project Gutenberg Literary Archive Foundation is a non profit\r
+501(c)(3) educational corporation organized under the laws of the\r
+state of Mississippi and granted tax exempt status by the Internal\r
+Revenue Service. The Foundation's EIN or federal tax identification\r
+number is 64-6221541. Its 501(c)(3) letter is posted at\r
+http://pglaf.org/fundraising. Contributions to the Project Gutenberg\r
+Literary Archive Foundation are tax deductible to the full extent\r
+permitted by U.S. federal laws and your state's laws.\r
+\r
+The Foundation's principal office is located at 4557 Melan Dr. S.\r
+Fairbanks, AK, 99712., but its volunteers and employees are scattered\r
+throughout numerous locations. Its business office is located at\r
+809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887, email\r
+business@pglaf.org. Email contact links and up to date contact\r
+information can be found at the Foundation's web site and official\r
+page at http://pglaf.org\r
+\r
+For additional contact information:\r
+ Dr. Gregory B. Newby\r
+ Chief Executive and Director\r
+ gbnewby@pglaf.org\r
+\r
+\r
+Section 4. Information about Donations to the Project Gutenberg\r
+Literary Archive Foundation\r
+\r
+Project Gutenberg-tm depends upon and cannot survive without wide\r
+spread public support and donations to carry out its mission of\r
+increasing the number of public domain and licensed works that can be\r
+freely distributed in machine readable form accessible by the widest\r
+array of equipment including outdated equipment. Many small donations\r
+($1 to $5,000) are particularly important to maintaining tax exempt\r
+status with the IRS.\r
+\r
+The Foundation is committed to complying with the laws regulating\r
+charities and charitable donations in all 50 states of the United\r
+States. Compliance requirements are not uniform and it takes a\r
+considerable effort, much paperwork and many fees to meet and keep up\r
+with these requirements. We do not solicit donations in locations\r
+where we have not received written confirmation of compliance. To\r
+SEND DONATIONS or determine the status of compliance for any\r
+particular state visit http://pglaf.org\r
+\r
+While we cannot and do not solicit contributions from states where we\r
+have not met the solicitation requirements, we know of no prohibition\r
+against accepting unsolicited donations from donors in such states who\r
+approach us with offers to donate.\r
+\r
+International donations are gratefully accepted, but we cannot make\r
+any statements concerning tax treatment of donations received from\r
+outside the United States. U.S. laws alone swamp our small staff.\r
+\r
+Please check the Project Gutenberg Web pages for current donation\r
+methods and addresses. Donations are accepted in a number of other\r
+ways including including checks, online payments and credit card\r
+donations. To donate, please visit: http://pglaf.org/donate\r
+\r
+\r
+Section 5. General Information About Project Gutenberg-tm electronic\r
+works.\r
+\r
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm\r
+concept of a library of electronic works that could be freely shared\r
+with anyone. For thirty years, he produced and distributed Project\r
+Gutenberg-tm eBooks with only a loose network of volunteer support.\r
+\r
+\r
+Project Gutenberg-tm eBooks are often created from several printed\r
+editions, all of which are confirmed as Public Domain in the U.S.\r
+unless a copyright notice is included. Thus, we do not necessarily\r
+keep eBooks in compliance with any particular paper edition.\r
+\r
+\r
+Most people start at our Web site which has the main PG search facility:\r
+\r
+ http://www.gutenberg.net\r
+\r
+This Web site includes information about Project Gutenberg-tm,\r
+including how to make donations to the Project Gutenberg Literary\r
+Archive Foundation, how to help produce our new eBooks, and how to\r
+subscribe to our email newsletter to hear about new eBooks.\r

+
+## Description
+
+This is the same as minimal-ws-server-ring, but with the
+inclusion of a ws client connection to https://libwebsockets.org
+using the dumb-increment protocol feeding the ringbuffer.
+
+Each client that connect to this server receives the content that
+had arrived on the client connection feeding the ringbuffer proxied
+to their browser window over a ws connection.
+
+## Usage
+
+```

+
+Visit http://localhost:7681 on multiple browser windows
+
+Data received on the remote wss connection is copied to all open browser windows.
+
+A ringbuffer holds up to 8 lines of text in the server, and the browser shows

+# lws minimal example for JWE
+
+Demonstrates how to encrypt and decrypt using JWE and JWK, providing a
+commandline tool for creating encrypted JWE and decoding them.
+
+## build
+
+```
+ $ cmake . && make
+```
+
+## usage
+
+Stdin is either the plaintext (if encrypting) or JWE (if decrypting).
+
+Stdout is either the JWE (if encrypting) or plaintext (if decrypting).
+
+You must pass a private or public key JWK file in the -k option if encrypting,
+and must pass a private key JWK file in the -k option if decrypting. To be
+clear, for asymmetric keys the public part of the key is required to encrypt,
+and the private part required to decrypt.
+
+For convenience, a pair of public and private keys are provided,
+`key-rsa-4096.private` and `key-rsa-4096.pub`, these were produced with just
+
+```
+ $ lws-crypto-jwk -t RSA -b 4096 --public key-rsa-4096.pub >key-rsa-4096.private
+```
+
+Similar keys for EC modes may be produced with
+
+```
+ $ lws-crypto-jwk -t EC -v P-256 --public key-ecdh-p-256.pub >key-ecdh-p-256.private
+```
+
+and for AES ("octet") symmetric keys
+
+```
+ $ lws-crypto-jwk -t OCT -b 128 >key-aes-128.private
+```
+
+JWEs produced with openssl and mbedtls backends are completely interchangeable.
+
+Commandline option|Meaning
+---|---
+-d <loglevel>|Debug verbosity in decimal, eg, -d15
+-e "<cek cipher alg> <payload enc alg>"|Encrypt (default is decrypt), eg, -e "RSA1_5 A128CBC-HS256". For decrypt, the cipher information comes from the input JWE.
+-k <jwk file>|JWK file to encrypt or decrypt with
+-c|Format the JWE as a linebroken C string
+-f|Output flattened representation (instead of compact by default)
+
+```
+ $ echo -n "plaintext0123456" | ./lws-crypto-jwe -k key-rsa-4096.private -e "RSA1_5 A128CBC-HS256"

+You can also pipe the output of the encrypt action directly into the decrypt

+# lws minimal example for JWK
+
+Demonstrates how to generate and format any kind of supported new random JWK keys.
+
+The full private key is output to stdout, a version of the key with the private
+part removed and some metadata adapted can be saved to a file at the same time
+using `--public <file>`. In the public form, `key_ops` and `use` elements are
+adjusted to remove activities that require a private key.
+
+Key elements are output in strict RFC7638 lexicographic order as required by
+some applications.
+
+Keys produced with openssl and mbedtls backends are completely interchangeable.
+
+## build
+
+```
+ $ cmake . && make
+```
+
+## usage
+
+Commandline option|Meaning
+---|---
+-d <loglevel>|Debug verbosity in decimal, eg, -d15
+-t <type>|RSA, OCT or EC
+-b <bits>|For RSA and OCT, key size in bits
+-v <curve>|For EC keys, the curve, eg, "P-384"... this implies the key bits
+--kid "ID string"|Key identity string
+--use "use[ use]"|Key use restriction (mutually exclusive with --key-ops): sig, enc
+--alg <alg>|Specify the algorithm the key is designed for, eg "RSA1_5"
+--key-ops "op[ op]"|Key valid operations (mutually exclusive with --use): sign, verify, encrypt, decrypt, wrapKey, unwrapKey, deriveKey, deriveBits
+-c|Format the jwk as a linebroken C string
+--public <filepath>|Only output the full, private key, not the public version first
+
+For legibility the example uses -c, however this
+
+```

+# lws minimal example for JWS
+
+Demonstrates how to sign and verify using compact JWS and JWK, providing a
+commandline tool for signing and verifying stdin.
+
+## build
+
+```
+ $ cmake . && make
+```
+
+## usage
+
+Stdin is either the plaintext (if signing) or compact JWS (if verifying).
+
+Stdout is either the JWE (if encrypting) or plaintext (if decrypting).
+
+You must pass a private or public key JWK file in the -k option if encrypting,
+and must pass a private key JWK file in the -k option if decrypting. To be
+clear, for asymmetric keys the public part of the key is required to encrypt,
+and the private part required to decrypt.
+
+For convenience, a pair of public and private keys are provided,
+`key-rsa-4096.private` and `key-rsa-4096.pub`, these were produced with just
+
+```
+ $ lws-crypto-jwk -t RSA -b 4096 --public key-rsa-4096.pub >key-rsa-4096.private
+```
+
+Similar keys for EC modes may be produced with
+
+```
+ $ lws-crypto-jwk -t EC -v P-256 --public key-ecdh-p-256.pub >key-ecdh-p-256.private
+```
+
+JWSs produced with openssl and mbedtls backends are completely interchangeable.
+
+Commandline option|Meaning
+---|---
+-d <loglevel>|Debug verbosity in decimal, eg, -d15
+-s "<signature alg>"|Sign (default is verify), eg, -e "ES256". For verify, the cipher information comes from the input JWS.
+-k <jwk file>|JWK file to sign or verify with... sign requires the key has its private part
+-c|Format the JWE as a linebroken C string
+-f|Output flattened representation (instead of compact by default)
+
+```
+ $ echo -n "plaintext0123456" | ./lws-crypto-jws -s "ES256" -k ec-p256.private

+```
+
+Notice the logging is on stderr, and the output alone on stdout.
+
+When signing, the compact representation of the JWS is output on stdout.
+
+When verifying, if the signature is valid the plaintext is output on stdout
+and the tool exits with a 0 exit code. Otherwise nothing is output on stdout
+and it exits with a nonzero exit code.

+# lws minimal example for X509
+
+The example shows how to:
+
+ - confirm one PEM cert or chain (-c) was signed by a trusted PEM cert (-t)
+ - convert a certificate public key to JWK
+ - convert a certificate public key and its private key PEM to a private JWK
+
+The examples work for EC and RSA certs and on mbedtls and OpenSSL the same.
+
+Notice the logging is on stderr, and only the JWK is output on stdout.

+# lws minimal dbus client
+
+This demonstrates nonblocking, asynchronous dbus method calls as the client.
+
+## build
+
+Using libdbus requires additional non-default include paths setting, same as
+is necessary for lws build described in ./lib/roles/dbus/README.md
+
+CMake can guess one path and the library name usually, see the README above
+for details of how to override for custom libdbus and cross build.
+
+Fedora example:
+```
+$ cmake .. -DLWS_DBUS_INCLUDE2="/usr/lib64/dbus-1.0/include"
+$ make
+```
+
+Ubuntu example:
+```
+$ cmake .. -DLWS_DBUS_INCLUDE2="/usr/lib/x86_64-linux-gnu/dbus-1.0/include"
+$ make
+```
+
+## usage
+
+Commandline option|Meaning
+---|---
+-d <loglevel>|Debug verbosity in decimal, eg, -d15
+
+The minimal client connects to the minimal dbus server example, which is
+expected to be listening on its default abstract unix domain socket path.
+
+It call the server Echo method with "Hello!" and returns to the event loop.
+When the reply comes, it prints the returned message.
+
+Afterwards it just sits there receiving unsolicited messages from the server
+example, until closed by the user.

+# lws minimal dbus ws proxy testclient
+
+This is a test client used to test `./minimal-examples/dbus-server/minimal-dbus-ws-proxy`
+
+It asks the minimal dbus ws proxy application to connect to libwebsockets.org
+over the mirror protocol. And it proxies back the ASCII packets used to
+communicate the mirror sample drawing vectors over dbus to this test client
+if you draw on the [mirror example app](https://libwebsockets.org/testserver/)
+in a browser.
+
+## build
+
+Using libdbus requires additional non-default include paths setting, same as
+is necessary for lws build described in ./lib/roles/dbus/README.md
+
+CMake can guess one path and the library name usually, see the README above
+for details of how to override for custom libdbus and cross build.
+
+Fedora example:
+```
+$ cmake .. -DLWS_DBUS_INCLUDE2="/usr/lib64/dbus-1.0/include"
+$ make
+```
+
+Ubuntu example:
+```
+$ cmake .. -DLWS_DBUS_INCLUDE2="/usr/lib/x86_64-linux-gnu/dbus-1.0/include"
+$ make
+```
+
+## usage
+
+Commandline option|Meaning
+---|---
+-d <loglevel>|Debug verbosity in decimal, eg, -d15
+
+This connects to the minimal-dbus-ws-proxy example running in another terminal.
+

+Using libdbus requires additional non-default include paths setting, same as
+is necessary for lws build described in ./lib/roles/dbus/README.md
+
+CMake can guess one path and the library name usually, see the README above
+for details of how to override for custom libdbus and cross build.
+
+Fedora example:
+```
+$ cmake .. -DLWS_DBUS_INCLUDE2="/usr/lib64/dbus-1.0/include"
+$ make
+```
+
+Ubuntu example:
+```
+$ cmake .. -DLWS_DBUS_INCLUDE2="/usr/lib/x86_64-linux-gnu/dbus-1.0/include"
+$ make
+```
+

+--session | Bind to session bus instead of creating private abstract unix socket
+
+By default the minimal server listens using its own abstract unix socket
+at `unix:abstract=org.libwebsockets.test`.
+
+You can also run it instead as a participant on the session bus, without its own
+unix socket, by giving `--session`.
+
+### Examples using the default private abstract unix socket
+
+```
+ $ ./lws-minimal-dbus-server
+[2018/10/03 07:08:02:6448] USER: LWS minimal dbus server
+[2018/10/03 07:08:02:6693] NOTICE: Creating Vhost 'default' port 0, 1 protocols, IPv6 off
+...
+```
+
+You can communicate with the dbus server over its private abstract socket using, eg
+
+```
+$ gdbus introspect --address unix:abstract=org.libwebsockets.test --dest org.libwebsockets.test --object-path /org/libwebsockets/test
+node /org/example/TestObject {
+ interface org.freedesktop.DBus.Introspectable {
+ methods:
+ Introspect(out s data);
+ signals:
+ properties:
+ };
+ interface org.freedesktop.DBus.Properties {
+ methods:
+ Get(in s interface,
+...
+```
+
+```
+$ gdbus call --address unix:abstract=org.libwebsockets.test --dest org.libwebsockets.test --object-path /org/libwebsockets/test --method org.libwebsockets.test.Echo HELLO
+('HELLO',)
+```
+
+### Examples using the DBUS session bus
+
+```
+ $ ./lws-minimal-dbus-server --session
+[2018/10/03 07:08:02:6448] USER: LWS minimal dbus server
+[2018/10/03 07:08:02:6693] NOTICE: Creating Vhost 'default' port 0, 1 protocols, IPv6 off
+...
+```
+
+You can communicate with the dbus server over the session bus using, eg
+
+```
+$ gdbus introspect --session --dest org.libwebsockets.test --object-path /org/libwebsockets/test
+node /org/example/TestObject {
+ interface org.freedesktop.DBus.Introspectable {
+ methods:
+ Introspect(out s data);
+ signals:
+ properties:
+ };
+ interface org.freedesktop.DBus.Properties {
+ methods:
+ Get(in s interface,
+...
+```
+
+```
+$ gdbus call --session --dest org.libwebsockets.test --object-path /org/libwebsockets/test --method org.libwebsockets.test.Echo HELLO
+('HELLO',)
+```

+# lws minimal dbus ws proxy
+
+This is an application which presents a DBUS server on one side, and a
+websocket client proxy on the other.
+
+You connect to it over DBUS, send a Connect method on its interface giving
+a URI and a ws subprotocol name.
+
+It replies with a string "Connecting" if all is well.
+
+Connection progress (including close) is then provided using type 7 messages
+sent back to the dbus client.
+
+Payload from the ws connection is provided using type 6 messages sent back to
+the dbus client.
+
+## build
+
+Using libdbus requires additional non-default include paths setting, same as
+is necessary for lws build described in ./lib/roles/dbus/README.md
+
+CMake can guess one path and the library name usually, see the README above
+for details of how to override for custom libdbus and cross build.
+
+Fedora example:
+```
+$ cmake .. -DLWS_DBUS_INCLUDE2="/usr/lib64/dbus-1.0/include"
+$ make
+```
+
+Ubuntu example:
+```
+$ cmake .. -DLWS_DBUS_INCLUDE2="/usr/lib/x86_64-linux-gnu/dbus-1.0/include"
+$ make
+```
+
+## Configuration
+
+The dbus-ws-proxy server tries to register its actual bus name with the SYSTEM
+bus in DBUS. If it fails, eg because of insufficient permissions on the user,
+then it continues without that and starts its own daemon normally.
+
+The main dbus daemon must be told how to accept these registrations if that's
+what you want. A config file is provided that tells dbus to allow the
+well-known busname for this daemon to be registered, but only by root.
+
+```
+$ sudo cp org.libwebsockets.wsclientproxy.conf /etc/dbus-1/system.d
+$ sudo systemctl restart dbus
+```
+
+## usage
+
+Run the dbus-ws-proxy server, then start lws-minimal-dbus-ws-proxy-testclient in
+another terminal.
+
+This test app sends a random line drawing message to the mirror example on
+https://libwebsockets.org/testserver every couple of seconds, and displays
+any received messages (such as its own sends mirrored back, or anything
+drawn in the canvas in a browser).
+

+ * ws protocol handler plugin for dbus ws proxy
+ *
+ * Written in 2010-2019 by Andy Green <andy@warmcat.com>
+ *
+ * This file is made available under the Creative Commons CC0 1.0
+ * Universal Public Domain Dedication.
+ *
+ * This proxies outgoing ws client connections on DBUS. So a DBUS client can
+ * reach out and get remote WS payloads in both directions.
+ *
+ * DEVELOPER NOTE
+ *
+ * Two worlds, dbus and ws, collide in this file.
+ *
+ * There main thing keeping it sane is both worlds are running in the same
+ * thread and on the same event loop. Although things may happen completely
+ * asynchronously in both worlds, the logical reaction to those events are
+ * serialized in a single event loop doing one thing at a time.
+ *
+ * So while you are servicing an event in the ws world, you can be certain the
+ * logical state of any related dbus thing cannot change underneath you, until
+ * you return back to the event loop, and vice versa. So other-world objects
+ * can't be freed, other-world handles can't close etc while you are servicing
+ * in your world.
+ *
+ * Since all bets are off what happens next, and in which world, after you
+ * return back to the event loop though, an additional rule is needed: worlds
+ * must not allocate in objects owned by the other world. They must generate
+ * their own objects in their world and use those for allocations and state.
+ *
+ * For example in the dbus-world there is a struct lws_dbus_ctx_wsproxy with
+ * various state, but he is subject to deletion by events in dbus-world. If
+ * the ws-world stored things there, they are subject to going out of scope
+ * at the whim of the dbus connection without the ws world hearing about it and
+ * cleanly deallocaing them. So the ws world must keep his own pss that remains
+ * in scope until the ws link closes for allocations from ws-world.
+ *
+ * In this application there's a point of contact between the worlds, a ring
+ * buffer allocated in ws world when the ws connection is established, and
+ * deallocated when the ws connection is closed. The DBUS world needs to put
+ * things in this ringbuffer. But the way lws_ring works, when the message
+ * allocated in DBUS world is queued on the ringbuffer, the ringbuffer itself
+ * takes responsibility for deallocation. So there is no problem.

+
+This demonstrates how to dump information from the peer
+certificate largely independent of the tls backend.
+
+The application goes to https://warmcat.com and receives the page data.
+
+Before receiving the page it dumps information on the server's cert.
+
+This works independently of the tls backend being OpenSSL or mbedTLS.
+
+However the public keys cannot be compared between the two tls
+backends, since they produce different representations.

+# lws minimal http client custom headers
+
+This http client application shows how to send and receive custom headers.
+
+This currently only works on http 1, so the app forces that even if h2 enables.
+
+## build
+
+```
+ $ cmake . && make
+```
+
+## usage
+
+Commandline option|Meaning
+---|---
+-d <loglevel>|Debug verbosity in decimal, eg, -d15
+-l| Connect to https://localhost:7681 and accept selfsigned cert
+-n|no TLS
+
+The app looks for a custom header "test-custom-header" sent by warmcat.com.
+
+```
+ $ ./lws-minimal-http-client-custom-headers

+You can use the -n and -l to make this test app connect to localhost:7681 over http,

+# lws minimal http client multi
+
+## build
+
+```
+ $ cmake . && make
+```
+
+## usage
+
+The application goes to https://warmcat.com and receives the page data
+same as minimal http client.
+
+However it does it for 8 client connections concurrently.
+
+## Commandline Options
+
+Option|Meaning
+---|---
+-s|Stagger the connections by 100ms, the last by 1s
+-p|Use http/1.1 pipelining or h2 simultaneous streams
+--h1|Force http/1 only
+-l|Connect to server on https://localhost:7681 instead of https://warmcat.com:443
+-n|Read numbered files like /1.png, /2.png etc. Default is just read /

+ *
+ * This file is made available under the Creative Commons CC0 1.0
+ * Universal Public Domain Dedication.
+ *
+ * This demonstrates the a minimal http client using lws, which makes
+ * 8 downloads simultaneously from warmcat.com.
+ *
+ * Currently that takes the form of 8 individual simultaneous tcp and
+ * tls connections, which happen concurrently. Notice that the ordering
+ * of the returned payload may be intermingled for the various connections.
+ *
+ * By default the connections happen all together at the beginning and operate
+ * concurrently, which is fast. However this is resource-intenstive, there are
+ * 8 tcp connections, 8 tls tunnels on both the client and server. You can
+ * instead opt to have the connections happen one after the other inside a
+ * single tcp connection and tls tunnel, using HTTP/1.1 pipelining. To be
+ * eligible to be pipelined on another existing connection to the same server,
+ * the client connection must have the LCCSCF_PIPELINE flag on its
+ * info.ssl_connection member (this is independent of whether the connection
+ * is in ssl mode or not).
+ *
+ * HTTP/1.0: Pipelining only possible if Keep-Alive: yes sent by server
+ * HTTP/1.1: always possible... serializes requests
+ * HTTP/2: always possible... all requests sent as individual streams in parallel

+# lws minimal http client POST
+
+This example demonstrates a multipart POST to
+
+https://libwebsockets.org/testserver/formtest
+
+setting both a form variable and uploading a
+short file.
+
+The result of the POST form processing is captured
+and displayed in a hexdump.
+
+This is programmatically POSTing to the same
+form you can access at
+
+https://libwebsockets.org/testserver
+
+in the "POST" tab with file upload.
+
+By default the client action occurs using http/2 if
+your lws was built with `-DLWS_WITH_HTTP2=1`.
+

+# lws minimal http server basic auth
+
+This demonstrates how to protect a mount using a password
+file outside of the mount itself.
+
+The demo has two mounts, a normal one at / and one protected
+by basic auth at /secret.
+
+The file at ./ba-passwords contains valid user:password
+combinations.
+
+## Discovering the authenticated user
+
+After a successful authentication, the `WSI_TOKEN_HTTP_AUTHORIZATION` token
+contains the authenticated username.
+
+## build
+
+```
+ $ cmake . && make
+```
+
+## usage
+
+```
+ $ ./lws-minimal-http-server-basic-auth
+[2018/04/19 08:40:05:1333] USER: LWS minimal http server basic auth | visit http://localhost:7681
+[2018/04/19 08:40:05:1333] NOTICE: Creating Vhost 'default' port 7681, 1 protocols, IPv6 off
+```
+
+Visit http://localhost:7681, and follow the link there to the secret area.
+
+Give your browser "user" and "password" as the credentials.

+# lws minimal http server deaddrop
+
+This demonstrates how you can leverage the lws deaddrop plugin to make a
+secure, modern html5 file upload and sharing application.
+
+The demo is protected by basic auth credentials defined in the file at
+./ba-passwords - by default the credentials are user: user1, password: password;
+and user: user2, password: password again.
+
+You can upload files and have them appear on a shared, downloadable list that
+is dynamically updated to all clients open on the page. Only the authenticated
+uploader is able to delete the files he uploaded.
+
+Multiple simultaneous ongoing file uploads are supported.
+
+## build
+
+To build this standalone, you must tell cmake where the lws source tree
+./plugins directory can be found, since it relies on including the source
+of the raw-proxy plugin.
+
+```
+ $ cmake . -DLWS_PLUGINS_DIR=~/libwebsockets/plugins && make
+```
+
+## usage
+
+```

+Commandline option|Meaning
+---|---
+-d <loglevel>|Debug verbosity in decimal, eg, -d15
+--uv|Use the libuv event library (lws must have been configured with `-DLWS_WITH_LIBUV=1`)
+--event|Use the libevent library (lws must have been configured with `-DLWS_WITH_LIBEVENT=1`)
+--ev|Use the libev event library (lws must have been configured with `-DLWS_WITH_LIBEV=1`)

+Notice libevent and libev cannot coexist in the one library. But all the other combinations are OK.
+
+x|libuv|libevent|libev
+---|---|---|---
+libuv|-|OK|OK
+libevent|OK|-|no
+libev|OK|no|-
+
+This demonstrates having lws take part in a libuv loop owned by
+something else, with its own objects running in the loop.
+
+Lws can join the loop, and clean up perfectly after itself without
+leaving anything behind or making trouble in the larger loop, which
+does not need to stop during lws creation or destruction.
+
+First the foreign loop is created with a 1s timer, and runs alone for 5s.
+
+Then the lws context is created inside the timer callback and runs for 10s...
+during this period you can visit http://localhost:7681 for normal lws
+service using the foreign loop.
+
+After the 10s are up, the lws context is destroyed inside the foreign loop
+timer. The foreign loop runs alone again for a further 5s and then
+exits itself.

+ *
+ * You choose the event loop to work with at runtime, by giving the

+ *
+ * To keep it simple, it serves stuff from the subdirectory

+THE PREFACE\r
+\r
+The artist is the creator of beautiful things. To reveal art and\r
+conceal the artist is art's aim. The critic is he who can translate\r
+into another manner or a new material his impression of beautiful\r
+things.\r
+\r
+The highest as the lowest form of criticism is a mode of autobiography.\r
+Those who find ugly meanings in beautiful things are corrupt without\r
+being charming. This is a fault.\r
+\r
+Those who find beautiful meanings in beautiful things are the\r
+cultivated. For these there is hope. They are the elect to whom\r
+beautiful things mean only beauty.\r
+\r
+There is no such thing as a moral or an immoral book. Books are well\r
+written, or badly written. That is all.\r
+\r
+The nineteenth century dislike of realism is the rage of Caliban seeing\r
+his own face in a glass.\r
+\r
+The nineteenth century dislike of romanticism is the rage of Caliban\r
+not seeing his own face in a glass. The moral life of man forms part\r
+of the subject-matter of the artist, but the morality of art consists\r
+in the perfect use of an imperfect medium. No artist desires to prove\r
+anything. Even things that are true can be proved. No artist has\r
+ethical sympathies. An ethical sympathy in an artist is an\r
+unpardonable mannerism of style. No artist is ever morbid. The artist\r
+can express everything. Thought and language are to the artist\r
+instruments of an art. Vice and virtue are to the artist materials for\r
+an art. From the point of view of form, the type of all the arts is\r
+the art of the musician. From the point of view of feeling, the\r
+actor's craft is the type. All art is at once surface and symbol.\r
+Those who go beneath the surface do so at their peril. Those who read\r
+the symbol do so at their peril. It is the spectator, and not life,\r
+that art really mirrors. Diversity of opinion about a work of art\r
+shows that the work is new, complex, and vital. When critics disagree,\r
+the artist is in accord with himself. We can forgive a man for making\r
+a useful thing as long as he does not admire it. The only excuse for\r
+making a useless thing is that one admires it intensely.\r
+\r
+ All art is quite useless.\r

+CHAPTER 1\r
+\r
+The studio was filled with the rich odour of roses, and when the light\r
+summer wind stirred amidst the trees of the garden, there came through\r
+the open door the heavy scent of the lilac, or the more delicate\r
+perfume of the pink-flowering thorn.\r
+\r
+From the corner of the divan of Persian saddle-bags on which he was\r
+lying, smoking, as was his custom, innumerable cigarettes, Lord Henry\r
+Wotton could just catch the gleam of the honey-sweet and honey-coloured\r
+blossoms of a laburnum, whose tremulous branches seemed hardly able to\r
+bear the burden of a beauty so flamelike as theirs; and now and then\r
+the fantastic shadows of birds in flight flitted across the long\r
+tussore-silk curtains that were stretched in front of the huge window,\r
+producing a kind of momentary Japanese effect, and making him think of\r
+those pallid, jade-faced painters of Tokyo who, through the medium of\r
+an art that is necessarily immobile, seek to convey the sense of\r
+swiftness and motion. The sullen murmur of the bees shouldering their\r
+way through the long unmown grass, or circling with monotonous\r
+insistence round the dusty gilt horns of the straggling woodbine,\r
+seemed to make the stillness more oppressive. The dim roar of London\r
+was like the bourdon note of a distant organ.\r
+\r
+In the centre of the room, clamped to an upright easel, stood the\r
+full-length portrait of a young man of extraordinary personal beauty,\r
+and in front of it, some little distance away, was sitting the artist\r
+himself, Basil Hallward, whose sudden disappearance some years ago\r
+caused, at the time, such public excitement and gave rise to so many\r
+strange conjectures.\r
+\r
+As the painter looked at the gracious and comely form he had so\r
+skilfully mirrored in his art, a smile of pleasure passed across his\r
+face, and seemed about to linger there. But he suddenly started up,\r
+and closing his eyes, placed his fingers upon the lids, as though he\r
+sought to imprison within his brain some curious dream from which he\r
+feared he might awake.\r
+\r
+"It is your best work, Basil, the best thing you have ever done," said\r
+Lord Henry languidly. "You must certainly send it next year to the\r
+Grosvenor. The Academy is too large and too vulgar. Whenever I have\r
+gone there, there have been either so many people that I have not been\r
+able to see the pictures, which was dreadful, or so many pictures that\r
+I have not been able to see the people, which was worse. The Grosvenor\r
+is really the only place."\r
+\r
+"I don't think I shall send it anywhere," he answered, tossing his head\r
+back in that odd way that used to make his friends laugh at him at\r
+Oxford. "No, I won't send it anywhere."\r
+\r
+Lord Henry elevated his eyebrows and looked at him in amazement through\r
+the thin blue wreaths of smoke that curled up in such fanciful whorls\r
+from his heavy, opium-tainted cigarette. "Not send it anywhere? My\r
+dear fellow, why? Have you any reason? What odd chaps you painters\r
+are! You do anything in the world to gain a reputation. As soon as\r
+you have one, you seem to want to throw it away. It is silly of you,\r
+for there is only one thing in the world worse than being talked about,\r
+and that is not being talked about. A portrait like this would set you\r
+far above all the young men in England, and make the old men quite\r
+jealous, if old men are ever capable of any emotion."\r
+\r
+"I know you will laugh at me," he replied, "but I really can't exhibit\r
+it. I have put too much of myself into it."\r
+\r
+Lord Henry stretched himself out on the divan and laughed.\r
+\r
+"Yes, I knew you would; but it is quite true, all the same."\r
+\r
+"Too much of yourself in it! Upon my word, Basil, I didn't know you\r
+were so vain; and I really can't see any resemblance between you, with\r
+your rugged strong face and your coal-black hair, and this young\r
+Adonis, who looks as if he was made out of ivory and rose-leaves. Why,\r
+my dear Basil, he is a Narcissus, and you--well, of course you have an\r
+intellectual expression and all that. But beauty, real beauty, ends\r
+where an intellectual expression begins. Intellect is in itself a mode\r
+of exaggeration, and destroys the harmony of any face. The moment one\r
+sits down to think, one becomes all nose, or all forehead, or something\r
+horrid. Look at the successful men in any of the learned professions.\r
+How perfectly hideous they are! Except, of course, in the Church. But\r
+then in the Church they don't think. A bishop keeps on saying at the\r
+age of eighty what he was told to say when he was a boy of eighteen,\r
+and as a natural consequence he always looks absolutely delightful.\r
+Your mysterious young friend, whose name you have never told me, but\r
+whose picture really fascinates me, never thinks. I feel quite sure of\r
+that. He is some brainless beautiful creature who should be always\r
+here in winter when we have no flowers to look at, and always here in\r
+summer when we want something to chill our intelligence. Don't flatter\r
+yourself, Basil: you are not in the least like him."\r
+\r
+"You don't understand me, Harry," answered the artist. "Of course I am\r
+not like him. I know that perfectly well. Indeed, I should be sorry\r
+to look like him. You shrug your shoulders? I am telling you the\r
+truth. There is a fatality about all physical and intellectual\r
+distinction, the sort of fatality that seems to dog through history the\r
+faltering steps of kings. It is better not to be different from one's\r
+fellows. The ugly and the stupid have the best of it in this world.\r
+They can sit at their ease and gape at the play. If they know nothing\r
+of victory, they are at least spared the knowledge of defeat. They\r
+live as we all should live--undisturbed, indifferent, and without\r
+disquiet. They neither bring ruin upon others, nor ever receive it\r
+from alien hands. Your rank and wealth, Harry; my brains, such as they\r
+are--my art, whatever it may be worth; Dorian Gray's good looks--we\r
+shall all suffer for what the gods have given us, suffer terribly."\r
+\r
+"Dorian Gray? Is that his name?" asked Lord Henry, walking across the\r
+studio towards Basil Hallward.\r
+\r
+"Yes, that is his name. I didn't intend to tell it to you."\r
+\r
+"But why not?"\r
+\r
+"Oh, I can't explain. When I like people immensely, I never tell their\r
+names to any one. It is like surrendering a part of them. I have\r
+grown to love secrecy. It seems to be the one thing that can make\r
+modern life mysterious or marvellous to us. The commonest thing is\r
+delightful if one only hides it. When I leave town now I never tell my\r
+people where I am going. If I did, I would lose all my pleasure. It\r
+is a silly habit, I dare say, but somehow it seems to bring a great\r
+deal of romance into one's life. I suppose you think me awfully\r
+foolish about it?"\r
+\r
+"Not at all," answered Lord Henry, "not at all, my dear Basil. You\r
+seem to forget that I am married, and the one charm of marriage is that\r
+it makes a life of deception absolutely necessary for both parties. I\r
+never know where my wife is, and my wife never knows what I am doing.\r
+When we meet--we do meet occasionally, when we dine out together, or go\r
+down to the Duke's--we tell each other the most absurd stories with the\r
+most serious faces. My wife is very good at it--much better, in fact,\r
+than I am. She never gets confused over her dates, and I always do.\r
+But when she does find me out, she makes no row at all. I sometimes\r
+wish she would; but she merely laughs at me."\r
+\r
+"I hate the way you talk about your married life, Harry," said Basil\r
+Hallward, strolling towards the door that led into the garden. "I\r
+believe that you are really a very good husband, but that you are\r
+thoroughly ashamed of your own virtues. You are an extraordinary\r
+fellow. You never say a moral thing, and you never do a wrong thing.\r
+Your cynicism is simply a pose."\r
+\r
+"Being natural is simply a pose, and the most irritating pose I know,"\r
+cried Lord Henry, laughing; and the two young men went out into the\r
+garden together and ensconced themselves on a long bamboo seat that\r
+stood in the shade of a tall laurel bush. The sunlight slipped over\r
+the polished leaves. In the grass, white daisies were tremulous.\r
+\r
+After a pause, Lord Henry pulled out his watch. "I am afraid I must be\r
+going, Basil," he murmured, "and before I go, I insist on your\r
+answering a question I put to you some time ago."\r
+\r
+"What is that?" said the painter, keeping his eyes fixed on the ground.\r
+\r
+"You know quite well."\r
+\r
+"I do not, Harry."\r
+\r
+"Well, I will tell you what it is. I want you to explain to me why you\r
+won't exhibit Dorian Gray's picture. I want the real reason."\r
+\r
+"I told you the real reason."\r
+\r
+"No, you did not. You said it was because there was too much of\r
+yourself in it. Now, that is childish."\r
+\r
+"Harry," said Basil Hallward, looking him straight in the face, "every\r
+portrait that is painted with feeling is a portrait of the artist, not\r
+of the sitter. The sitter is merely the accident, the occasion. It is\r
+not he who is revealed by the painter; it is rather the painter who, on\r
+the coloured canvas, reveals himself. The reason I will not exhibit\r
+this picture is that I am afraid that I have shown in it the secret of\r
+my own soul."\r
+\r
+Lord Henry laughed. "And what is that?" he asked.\r
+\r
+"I will tell you," said Hallward; but an expression of perplexity came\r
+over his face.\r
+\r
+"I am all expectation, Basil," continued his companion, glancing at him.\r
+\r
+"Oh, there is really very little to tell, Harry," answered the painter;\r
+"and I am afraid you will hardly understand it. Perhaps you will\r
+hardly believe it."\r
+\r
+Lord Henry smiled, and leaning down, plucked a pink-petalled daisy from\r
+the grass and examined it. "I am quite sure I shall understand it," he\r
+replied, gazing intently at the little golden, white-feathered disk,\r
+"and as for believing things, I can believe anything, provided that it\r
+is quite incredible."\r
+\r
+The wind shook some blossoms from the trees, and the heavy\r
+lilac-blooms, with their clustering stars, moved to and fro in the\r
+languid air. A grasshopper began to chirrup by the wall, and like a\r
+blue thread a long thin dragon-fly floated past on its brown gauze\r
+wings. Lord Henry felt as if he could hear Basil Hallward's heart\r
+beating, and wondered what was coming.\r
+\r
+"The story is simply this," said the painter after some time. "Two\r
+months ago I went to a crush at Lady Brandon's. You know we poor\r
+artists have to show ourselves in society from time to time, just to\r
+remind the public that we are not savages. With an evening coat and a\r
+white tie, as you told me once, anybody, even a stock-broker, can gain\r
+a reputation for being civilized. Well, after I had been in the room\r
+about ten minutes, talking to huge overdressed dowagers and tedious\r
+academicians, I suddenly became conscious that some one was looking at\r
+me. I turned half-way round and saw Dorian Gray for the first time.\r
+When our eyes met, I felt that I was growing pale. A curious sensation\r
+of terror came over me. I knew that I had come face to face with some\r
+one whose mere personality was so fascinating that, if I allowed it to\r
+do so, it would absorb my whole nature, my whole soul, my very art\r
+itself. I did not want any external influence in my life. You know\r
+yourself, Harry, how independent I am by nature. I have always been my\r
+own master; had at least always been so, till I met Dorian Gray.\r
+Then--but I don't know how to explain it to you. Something seemed to\r
+tell me that I was on the verge of a terrible crisis in my life. I had\r
+a strange feeling that fate had in store for me exquisite joys and\r
+exquisite sorrows. I grew afraid and turned to quit the room. It was\r
+not conscience that made me do so: it was a sort of cowardice. I take\r
+no credit to myself for trying to escape."\r
+\r
+"Conscience and cowardice are really the same things, Basil.\r
+Conscience is the trade-name of the firm. That is all."\r
+\r
+"I don't believe that, Harry, and I don't believe you do either.\r
+However, whatever was my motive--and it may have been pride, for I used\r
+to be very proud--I certainly struggled to the door. There, of course,\r
+I stumbled against Lady Brandon. 'You are not going to run away so\r
+soon, Mr. Hallward?' she screamed out. You know her curiously shrill\r
+voice?"\r
+\r
+"Yes; she is a peacock in everything but beauty," said Lord Henry,\r
+pulling the daisy to bits with his long nervous fingers.\r
+\r
+"I could not get rid of her. She brought me up to royalties, and\r
+people with stars and garters, and elderly ladies with gigantic tiaras\r
+and parrot noses. She spoke of me as her dearest friend. I had only\r
+met her once before, but she took it into her head to lionize me. I\r
+believe some picture of mine had made a great success at the time, at\r
+least had been chattered about in the penny newspapers, which is the\r
+nineteenth-century standard of immortality. Suddenly I found myself\r
+face to face with the young man whose personality had so strangely\r
+stirred me. We were quite close, almost touching. Our eyes met again.\r
+It was reckless of me, but I asked Lady Brandon to introduce me to him.\r
+Perhaps it was not so reckless, after all. It was simply inevitable.\r
+We would have spoken to each other without any introduction. I am sure\r
+of that. Dorian told me so afterwards. He, too, felt that we were\r
+destined to know each other."\r
+\r
+"And how did Lady Brandon describe this wonderful young man?" asked his\r
+companion. "I know she goes in for giving a rapid _precis_ of all her\r
+guests. I remember her bringing me up to a truculent and red-faced old\r
+gentleman covered all over with orders and ribbons, and hissing into my\r
+ear, in a tragic whisper which must have been perfectly audible to\r
+everybody in the room, the most astounding details. I simply fled. I\r
+like to find out people for myself. But Lady Brandon treats her guests\r
+exactly as an auctioneer treats his goods. She either explains them\r
+entirely away, or tells one everything about them except what one wants\r
+to know."\r
+\r
+"Poor Lady Brandon! You are hard on her, Harry!" said Hallward\r
+listlessly.\r
+\r
+"My dear fellow, she tried to found a _salon_, and only succeeded in\r
+opening a restaurant. How could I admire her? But tell me, what did\r
+she say about Mr. Dorian Gray?"\r
+\r
+"Oh, something like, 'Charming boy--poor dear mother and I absolutely\r
+inseparable. Quite forget what he does--afraid he--doesn't do\r
+anything--oh, yes, plays the piano--or is it the violin, dear Mr.\r
+Gray?' Neither of us could help laughing, and we became friends at\r
+once."\r
+\r
+"Laughter is not at all a bad beginning for a friendship, and it is far\r
+the best ending for one," said the young lord, plucking another daisy.\r
+\r
+Hallward shook his head. "You don't understand what friendship is,\r
+Harry," he murmured--"or what enmity is, for that matter. You like\r
+every one; that is to say, you are indifferent to every one."\r
+\r
+"How horribly unjust of you!" cried Lord Henry, tilting his hat back\r
+and looking up at the little clouds that, like ravelled skeins of\r
+glossy white silk, were drifting across the hollowed turquoise of the\r
+summer sky. "Yes; horribly unjust of you. I make a great difference\r
+between people. I choose my friends for their good looks, my\r
+acquaintances for their good characters, and my enemies for their good\r
+intellects. A man cannot be too careful in the choice of his enemies.\r
+I have not got one who is a fool. They are all men of some\r
+intellectual power, and consequently they all appreciate me. Is that\r
+very vain of me? I think it is rather vain."\r
+\r
+"I should think it was, Harry. But according to your category I must\r
+be merely an acquaintance."\r
+\r
+"My dear old Basil, you are much more than an acquaintance."\r
+\r
+"And much less than a friend. A sort of brother, I suppose?"\r
+\r
+"Oh, brothers! I don't care for brothers. My elder brother won't die,\r
+and my younger brothers seem never to do anything else."\r
+\r
+"Harry!" exclaimed Hallward, frowning.\r
+\r
+"My dear fellow, I am not quite serious. But I can't help detesting my\r
+relations. I suppose it comes from the fact that none of us can stand\r
+other people having the same faults as ourselves. I quite sympathize\r
+with the rage of the English democracy against what they call the vices\r
+of the upper orders. The masses feel that drunkenness, stupidity, and\r
+immorality should be their own special property, and that if any one of\r
+us makes an ass of himself, he is poaching on their preserves. When\r
+poor Southwark got into the divorce court, their indignation was quite\r
+magnificent. And yet I don't suppose that ten per cent of the\r
+proletariat live correctly."\r
+\r
+"I don't agree with a single word that you have said, and, what is\r
+more, Harry, I feel sure you don't either."\r
+\r
+Lord Henry stroked his pointed brown beard and tapped the toe of his\r
+patent-leather boot with a tasselled ebony cane. "How English you are\r
+Basil! That is the second time you have made that observation. If one\r
+puts forward an idea to a true Englishman--always a rash thing to\r
+do--he never dreams of considering whether the idea is right or wrong.\r
+The only thing he considers of any importance is whether one believes\r
+it oneself. Now, the value of an idea has nothing whatsoever to do\r
+with the sincerity of the man who expresses it. Indeed, the\r
+probabilities are that the more insincere the man is, the more purely\r
+intellectual will the idea be, as in that case it will not be coloured\r
+by either his wants, his desires, or his prejudices. However, I don't\r
+propose to discuss politics, sociology, or metaphysics with you. I\r
+like persons better than principles, and I like persons with no\r
+principles better than anything else in the world. Tell me more about\r
+Mr. Dorian Gray. How often do you see him?"\r
+\r
+"Every day. I couldn't be happy if I didn't see him every day. He is\r
+absolutely necessary to me."\r
+\r
+"How extraordinary! I thought you would never care for anything but\r
+your art."\r
+\r
+"He is all my art to me now," said the painter gravely. "I sometimes\r
+think, Harry, that there are only two eras of any importance in the\r
+world's history. The first is the appearance of a new medium for art,\r
+and the second is the appearance of a new personality for art also.\r
+What the invention of oil-painting was to the Venetians, the face of\r
+Antinous was to late Greek sculpture, and the face of Dorian Gray will\r
+some day be to me. It is not merely that I paint from him, draw from\r
+him, sketch from him. Of course, I have done all that. But he is much\r
+more to me than a model or a sitter. I won't tell you that I am\r
+dissatisfied with what I have done of him, or that his beauty is such\r
+that art cannot express it. There is nothing that art cannot express,\r
+and I know that the work I have done, since I met Dorian Gray, is good\r
+work, is the best work of my life. But in some curious way--I wonder\r
+will you understand me?--his personality has suggested to me an\r
+entirely new manner in art, an entirely new mode of style. I see\r
+things differently, I think of them differently. I can now recreate\r
+life in a way that was hidden from me before. 'A dream of form in days\r
+of thought'--who is it who says that? I forget; but it is what Dorian\r
+Gray has been to me. The merely visible presence of this lad--for he\r
+seems to me little more than a lad, though he is really over\r
+twenty--his merely visible presence--ah! I wonder can you realize all\r
+that that means? Unconsciously he defines for me the lines of a fresh\r
+school, a school that is to have in it all the passion of the romantic\r
+spirit, all the perfection of the spirit that is Greek. The harmony of\r
+soul and body--how much that is! We in our madness have separated the\r
+two, and have invented a realism that is vulgar, an ideality that is\r
+void. Harry! if you only knew what Dorian Gray is to me! You remember\r
+that landscape of mine, for which Agnew offered me such a huge price\r
+but which I would not part with? It is one of the best things I have\r
+ever done. And why is it so? Because, while I was painting it, Dorian\r
+Gray sat beside me. Some subtle influence passed from him to me, and\r
+for the first time in my life I saw in the plain woodland the wonder I\r
+had always looked for and always missed."\r
+\r
+"Basil, this is extraordinary! I must see Dorian Gray."\r
+\r
+Hallward got up from the seat and walked up and down the garden. After\r
+some time he came back. "Harry," he said, "Dorian Gray is to me simply\r
+a motive in art. You might see nothing in him. I see everything in\r
+him. He is never more present in my work than when no image of him is\r
+there. He is a suggestion, as I have said, of a new manner. I find\r
+him in the curves of certain lines, in the loveliness and subtleties of\r
+certain colours. That is all."\r
+\r
+"Then why won't you exhibit his portrait?" asked Lord Henry.\r
+\r
+"Because, without intending it, I have put into it some expression of\r
+all this curious artistic idolatry, of which, of course, I have never\r
+cared to speak to him. He knows nothing about it. He shall never know\r
+anything about it. But the world might guess it, and I will not bare\r
+my soul to their shallow prying eyes. My heart shall never be put\r
+under their microscope. There is too much of myself in the thing,\r
+Harry--too much of myself!"\r
+\r
+"Poets are not so scrupulous as you are. They know how useful passion\r
+is for publication. Nowadays a broken heart will run to many editions."\r
+\r
+"I hate them for it," cried Hallward. "An artist should create\r
+beautiful things, but should put nothing of his own life into them. We\r
+live in an age when men treat art as if it were meant to be a form of\r
+autobiography. We have lost the abstract sense of beauty. Some day I\r
+will show the world what it is; and for that reason the world shall\r
+never see my portrait of Dorian Gray."\r
+\r
+"I think you are wrong, Basil, but I won't argue with you. It is only\r
+the intellectually lost who ever argue. Tell me, is Dorian Gray very\r
+fond of you?"\r
+\r
+The painter considered for a few moments. "He likes me," he answered\r
+after a pause; "I know he likes me. Of course I flatter him\r
+dreadfully. I find a strange pleasure in saying things to him that I\r
+know I shall be sorry for having said. As a rule, he is charming to\r
+me, and we sit in the studio and talk of a thousand things. Now and\r
+then, however, he is horribly thoughtless, and seems to take a real\r
+delight in giving me pain. Then I feel, Harry, that I have given away\r
+my whole soul to some one who treats it as if it were a flower to put\r
+in his coat, a bit of decoration to charm his vanity, an ornament for a\r
+summer's day."\r
+\r
+"Days in summer, Basil, are apt to linger," murmured Lord Henry.\r
+"Perhaps you will tire sooner than he will. It is a sad thing to think\r
+of, but there is no doubt that genius lasts longer than beauty. That\r
+accounts for the fact that we all take such pains to over-educate\r
+ourselves. In the wild struggle for existence, we want to have\r
+something that endures, and so we fill our minds with rubbish and\r
+facts, in the silly hope of keeping our place. The thoroughly\r
+well-informed man--that is the modern ideal. And the mind of the\r
+thoroughly well-informed man is a dreadful thing. It is like a\r
+_bric-a-brac_ shop, all monsters and dust, with everything priced above\r
+its proper value. I think you will tire first, all the same. Some day\r
+you will look at your friend, and he will seem to you to be a little\r
+out of drawing, or you won't like his tone of colour, or something.\r
+You will bitterly reproach him in your own heart, and seriously think\r
+that he has behaved very badly to you. The next time he calls, you\r
+will be perfectly cold and indifferent. It will be a great pity, for\r
+it will alter you. What you have told me is quite a romance, a romance\r
+of art one might call it, and the worst of having a romance of any kind\r
+is that it leaves one so unromantic."\r
+\r
+"Harry, don't talk like that. As long as I live, the personality of\r
+Dorian Gray will dominate me. You can't feel what I feel. You change\r
+too often."\r
+\r
+"Ah, my dear Basil, that is exactly why I can feel it. Those who are\r
+faithful know only the trivial side of love: it is the faithless who\r
+know love's tragedies." And Lord Henry struck a light on a dainty\r
+silver case and began to smoke a cigarette with a self-conscious and\r
+satisfied air, as if he had summed up the world in a phrase. There was\r
+a rustle of chirruping sparrows in the green lacquer leaves of the ivy,\r
+and the blue cloud-shadows chased themselves across the grass like\r
+swallows. How pleasant it was in the garden! And how delightful other\r
+people's emotions were!--much more delightful than their ideas, it\r
+seemed to him. One's own soul, and the passions of one's\r
+friends--those were the fascinating things in life. He pictured to\r
+himself with silent amusement the tedious luncheon that he had missed\r
+by staying so long with Basil Hallward. Had he gone to his aunt's, he\r
+would have been sure to have met Lord Goodbody there, and the whole\r
+conversation would have been about the feeding of the poor and the\r
+necessity for model lodging-houses. Each class would have preached the\r
+importance of those virtues, for whose exercise there was no necessity\r
+in their own lives. The rich would have spoken on the value of thrift,\r
+and the idle grown eloquent over the dignity of labour. It was\r
+charming to have escaped all that! As he thought of his aunt, an idea\r
+seemed to strike him. He turned to Hallward and said, "My dear fellow,\r
+I have just remembered."\r
+\r
+"Remembered what, Harry?"\r
+\r
+"Where I heard the name of Dorian Gray."\r
+\r
+"Where was it?" asked Hallward, with a slight frown.\r
+\r
+"Don't look so angry, Basil. It was at my aunt, Lady Agatha's. She\r
+told me she had discovered a wonderful young man who was going to help\r
+her in the East End, and that his name was Dorian Gray. I am bound to\r
+state that she never told me he was good-looking. Women have no\r
+appreciation of good looks; at least, good women have not. She said\r
+that he was very earnest and had a beautiful nature. I at once\r
+pictured to myself a creature with spectacles and lank hair, horribly\r
+freckled, and tramping about on huge feet. I wish I had known it was\r
+your friend."\r
+\r
+"I am very glad you didn't, Harry."\r
+\r
+"Why?"\r
+\r
+"I don't want you to meet him."\r
+\r
+"You don't want me to meet him?"\r
+\r
+"No."\r
+\r
+"Mr. Dorian Gray is in the studio, sir," said the butler, coming into\r
+the garden.\r
+\r
+"You must introduce me now," cried Lord Henry, laughing.\r
+\r
+The painter turned to his servant, who stood blinking in the sunlight.\r
+"Ask Mr. Gray to wait, Parker: I shall be in in a few moments." The\r
+man bowed and went up the walk.\r
+\r
+Then he looked at Lord Henry. "Dorian Gray is my dearest friend," he\r
+said. "He has a simple and a beautiful nature. Your aunt was quite\r
+right in what she said of him. Don't spoil him. Don't try to\r
+influence him. Your influence would be bad. The world is wide, and\r
+has many marvellous people in it. Don't take away from me the one\r
+person who gives to my art whatever charm it possesses: my life as an\r
+artist depends on him. Mind, Harry, I trust you." He spoke very\r
+slowly, and the words seemed wrung out of him almost against his will.\r
+\r
+"What nonsense you talk!" said Lord Henry, smiling, and taking Hallward\r
+by the arm, he almost led him into the house.\r
+\r
+\r
+\r
+CHAPTER 2\r
+\r
+As they entered they saw Dorian Gray. He was seated at the piano, with\r
+his back to them, turning over the pages of a volume of Schumann's\r
+"Forest Scenes." "You must lend me these, Basil," he cried. "I want\r
+to learn them. They are perfectly charming."\r
+\r
+"That entirely depends on how you sit to-day, Dorian."\r
+\r
+"Oh, I am tired of sitting, and I don't want a life-sized portrait of\r
+myself," answered the lad, swinging round on the music-stool in a\r
+wilful, petulant manner. When he caught sight of Lord Henry, a faint\r
+blush coloured his cheeks for a moment, and he started up. "I beg your\r
+pardon, Basil, but I didn't know you had any one with you."\r
+\r
+"This is Lord Henry Wotton, Dorian, an old Oxford friend of mine. I\r
+have just been telling him what a capital sitter you were, and now you\r
+have spoiled everything."\r
+\r
+"You have not spoiled my pleasure in meeting you, Mr. Gray," said Lord\r
+Henry, stepping forward and extending his hand. "My aunt has often\r
+spoken to me about you. You are one of her favourites, and, I am\r
+afraid, one of her victims also."\r
+\r
+"I am in Lady Agatha's black books at present," answered Dorian with a\r
+funny look of penitence. "I promised to go to a club in Whitechapel\r
+with her last Tuesday, and I really forgot all about it. We were to\r
+have played a duet together--three duets, I believe. I don't know what\r
+she will say to me. I am far too frightened to call."\r
+\r
+"Oh, I will make your peace with my aunt. She is quite devoted to you.\r
+And I don't think it really matters about your not being there. The\r
+audience probably thought it was a duet. When Aunt Agatha sits down to\r
+the piano, she makes quite enough noise for two people."\r
+\r
+"That is very horrid to her, and not very nice to me," answered Dorian,\r
+laughing.\r
+\r
+Lord Henry looked at him. Yes, he was certainly wonderfully handsome,\r
+with his finely curved scarlet lips, his frank blue eyes, his crisp\r
+gold hair. There was something in his face that made one trust him at\r
+once. All the candour of youth was there, as well as all youth's\r
+passionate purity. One felt that he had kept himself unspotted from\r
+the world. No wonder Basil Hallward worshipped him.\r
+\r
+"You are too charming to go in for philanthropy, Mr. Gray--far too\r
+charming." And Lord Henry flung himself down on the divan and opened\r
+his cigarette-case.\r
+\r
+The painter had been busy mixing his colours and getting his brushes\r
+ready. He was looking worried, and when he heard Lord Henry's last\r
+remark, he glanced at him, hesitated for a moment, and then said,\r
+"Harry, I want to finish this picture to-day. Would you think it\r
+awfully rude of me if I asked you to go away?"\r
+\r
+Lord Henry smiled and looked at Dorian Gray. "Am I to go, Mr. Gray?"\r
+he asked.\r
+\r
+"Oh, please don't, Lord Henry. I see that Basil is in one of his sulky\r
+moods, and I can't bear him when he sulks. Besides, I want you to tell\r
+me why I should not go in for philanthropy."\r
+\r
+"I don't know that I shall tell you that, Mr. Gray. It is so tedious a\r
+subject that one would have to talk seriously about it. But I\r
+certainly shall not run away, now that you have asked me to stop. You\r
+don't really mind, Basil, do you? You have often told me that you\r
+liked your sitters to have some one to chat to."\r
+\r
+Hallward bit his lip. "If Dorian wishes it, of course you must stay.\r
+Dorian's whims are laws to everybody, except himself."\r
+\r
+Lord Henry took up his hat and gloves. "You are very pressing, Basil,\r
+but I am afraid I must go. I have promised to meet a man at the\r
+Orleans. Good-bye, Mr. Gray. Come and see me some afternoon in Curzon\r
+Street. I am nearly always at home at five o'clock. Write to me when\r
+you are coming. I should be sorry to miss you."\r
+\r
+"Basil," cried Dorian Gray, "if Lord Henry Wotton goes, I shall go,\r
+too. You never open your lips while you are painting, and it is\r
+horribly dull standing on a platform and trying to look pleasant. Ask\r
+him to stay. I insist upon it."\r
+\r
+"Stay, Harry, to oblige Dorian, and to oblige me," said Hallward,\r
+gazing intently at his picture. "It is quite true, I never talk when I\r
+am working, and never listen either, and it must be dreadfully tedious\r
+for my unfortunate sitters. I beg you to stay."\r
+\r
+"But what about my man at the Orleans?"\r
+\r
+The painter laughed. "I don't think there will be any difficulty about\r
+that. Sit down again, Harry. And now, Dorian, get up on the platform,\r
+and don't move about too much, or pay any attention to what Lord Henry\r
+says. He has a very bad influence over all his friends, with the\r
+single exception of myself."\r
+\r
+Dorian Gray stepped up on the dais with the air of a young Greek\r
+martyr, and made a little _moue_ of discontent to Lord Henry, to whom he\r
+had rather taken a fancy. He was so unlike Basil. They made a\r
+delightful contrast. And he had such a beautiful voice. After a few\r
+moments he said to him, "Have you really a very bad influence, Lord\r
+Henry? As bad as Basil says?"\r
+\r
+"There is no such thing as a good influence, Mr. Gray. All influence\r
+is immoral--immoral from the scientific point of view."\r
+\r
+"Why?"\r
+\r
+"Because to influence a person is to give him one's own soul. He does\r
+not think his natural thoughts, or burn with his natural passions. His\r
+virtues are not real to him. His sins, if there are such things as\r
+sins, are borrowed. He becomes an echo of some one else's music, an\r
+actor of a part that has not been written for him. The aim of life is\r
+self-development. To realize one's nature perfectly--that is what each\r
+of us is here for. People are afraid of themselves, nowadays. They\r
+have forgotten the highest of all duties, the duty that one owes to\r
+one's self. Of course, they are charitable. They feed the hungry and\r
+clothe the beggar. But their own souls starve, and are naked. Courage\r
+has gone out of our race. Perhaps we never really had it. The terror\r
+of society, which is the basis of morals, the terror of God, which is\r
+the secret of religion--these are the two things that govern us. And\r
+yet--"\r
+\r
+"Just turn your head a little more to the right, Dorian, like a good\r
+boy," said the painter, deep in his work and conscious only that a look\r
+had come into the lad's face that he had never seen there before.\r
+\r
+"And yet," continued Lord Henry, in his low, musical voice, and with\r
+that graceful wave of the hand that was always so characteristic of\r
+him, and that he had even in his Eton days, "I believe that if one man\r
+were to live out his life fully and completely, were to give form to\r
+every feeling, expression to every thought, reality to every dream--I\r
+believe that the world would gain such a fresh impulse of joy that we\r
+would forget all the maladies of mediaevalism, and return to the\r
+Hellenic ideal--to something finer, richer than the Hellenic ideal, it\r
+may be. But the bravest man amongst us is afraid of himself. The\r
+mutilation of the savage has its tragic survival in the self-denial\r
+that mars our lives. We are punished for our refusals. Every impulse\r
+that we strive to strangle broods in the mind and poisons us. The body\r
+sins once, and has done with its sin, for action is a mode of\r
+purification. Nothing remains then but the recollection of a pleasure,\r
+or the luxury of a regret. The only way to get rid of a temptation is\r
+to yield to it. Resist it, and your soul grows sick with longing for\r
+the things it has forbidden to itself, with desire for what its\r
+monstrous laws have made monstrous and unlawful. It has been said that\r
+the great events of the world take place in the brain. It is in the\r
+brain, and the brain only, that the great sins of the world take place\r
+also. You, Mr. Gray, you yourself, with your rose-red youth and your\r
+rose-white boyhood, you have had passions that have made you afraid,\r
+thoughts that have filled you with terror, day-dreams and sleeping\r
+dreams whose mere memory might stain your cheek with shame--"\r
+\r
+"Stop!" faltered Dorian Gray, "stop! you bewilder me. I don't know\r
+what to say. There is some answer to you, but I cannot find it. Don't\r
+speak. Let me think. Or, rather, let me try not to think."\r
+\r
+For nearly ten minutes he stood there, motionless, with parted lips and\r
+eyes strangely bright. He was dimly conscious that entirely fresh\r
+influences were at work within him. Yet they seemed to him to have\r
+come really from himself. The few words that Basil's friend had said\r
+to him--words spoken by chance, no doubt, and with wilful paradox in\r
+them--had touched some secret chord that had never been touched before,\r
+but that he felt was now vibrating and throbbing to curious pulses.\r
+\r
+Music had stirred him like that. Music had troubled him many times.\r
+But music was not articulate. It was not a new world, but rather\r
+another chaos, that it created in us. Words! Mere words! How\r
+terrible they were! How clear, and vivid, and cruel! One could not\r
+escape from them. And yet what a subtle magic there was in them! They\r
+seemed to be able to give a plastic form to formless things, and to\r
+have a music of their own as sweet as that of viol or of lute. Mere\r
+words! Was there anything so real as words?\r
+\r
+Yes; there had been things in his boyhood that he had not understood.\r
+He understood them now. Life suddenly became fiery-coloured to him.\r
+It seemed to him that he had been walking in fire. Why had he not\r
+known it?\r
+\r
+With his subtle smile, Lord Henry watched him. He knew the precise\r
+psychological moment when to say nothing. He felt intensely\r
+interested. He was amazed at the sudden impression that his words had\r
+produced, and, remembering a book that he had read when he was sixteen,\r
+a book which had revealed to him much that he had not known before, he\r
+wondered whether Dorian Gray was passing through a similar experience.\r
+He had merely shot an arrow into the air. Had it hit the mark? How\r
+fascinating the lad was!\r
+\r
+Hallward painted away with that marvellous bold touch of his, that had\r
+the true refinement and perfect delicacy that in art, at any rate comes\r
+only from strength. He was unconscious of the silence.\r
+\r
+"Basil, I am tired of standing," cried Dorian Gray suddenly. "I must\r
+go out and sit in the garden. The air is stifling here."\r
+\r
+"My dear fellow, I am so sorry. When I am painting, I can't think of\r
+anything else. But you never sat better. You were perfectly still.\r
+And I have caught the effect I wanted--the half-parted lips and the\r
+bright look in the eyes. I don't know what Harry has been saying to\r
+you, but he has certainly made you have the most wonderful expression.\r
+I suppose he has been paying you compliments. You mustn't believe a\r
+word that he says."\r
+\r
+"He has certainly not been paying me compliments. Perhaps that is the\r
+reason that I don't believe anything he has told me."\r
+\r
+"You know you believe it all," said Lord Henry, looking at him with his\r
+dreamy languorous eyes. "I will go out to the garden with you. It is\r
+horribly hot in the studio. Basil, let us have something iced to\r
+drink, something with strawberries in it."\r
+\r
+"Certainly, Harry. Just touch the bell, and when Parker comes I will\r
+tell him what you want. I have got to work up this background, so I\r
+will join you later on. Don't keep Dorian too long. I have never been\r
+in better form for painting than I am to-day. This is going to be my\r
+masterpiece. It is my masterpiece as it stands."\r
+\r
+Lord Henry went out to the garden and found Dorian Gray burying his\r
+face in the great cool lilac-blossoms, feverishly drinking in their\r
+perfume as if it had been wine. He came close to him and put his hand\r
+upon his shoulder. "You are quite right to do that," he murmured.\r
+"Nothing can cure the soul but the senses, just as nothing can cure the\r
+senses but the soul."\r
+\r
+The lad started and drew back. He was bareheaded, and the leaves had\r
+tossed his rebellious curls and tangled all their gilded threads.\r
+There was a look of fear in his eyes, such as people have when they are\r
+suddenly awakened. His finely chiselled nostrils quivered, and some\r
+hidden nerve shook the scarlet of his lips and left them trembling.\r
+\r
+"Yes," continued Lord Henry, "that is one of the great secrets of\r
+life--to cure the soul by means of the senses, and the senses by means\r
+of the soul. You are a wonderful creation. You know more than you\r
+think you know, just as you know less than you want to know."\r
+\r
+Dorian Gray frowned and turned his head away. He could not help liking\r
+the tall, graceful young man who was standing by him. His romantic,\r
+olive-coloured face and worn expression interested him. There was\r
+something in his low languid voice that was absolutely fascinating.\r
+His cool, white, flowerlike hands, even, had a curious charm. They\r
+moved, as he spoke, like music, and seemed to have a language of their\r
+own. But he felt afraid of him, and ashamed of being afraid. Why had\r
+it been left for a stranger to reveal him to himself? He had known\r
+Basil Hallward for months, but the friendship between them had never\r
+altered him. Suddenly there had come some one across his life who\r
+seemed to have disclosed to him life's mystery. And, yet, what was\r
+there to be afraid of? He was not a schoolboy or a girl. It was\r
+absurd to be frightened.\r
+\r
+"Let us go and sit in the shade," said Lord Henry. "Parker has brought\r
+out the drinks, and if you stay any longer in this glare, you will be\r
+quite spoiled, and Basil will never paint you again. You really must\r
+not allow yourself to become sunburnt. It would be unbecoming."\r
+\r
+"What can it matter?" cried Dorian Gray, laughing, as he sat down on\r
+the seat at the end of the garden.\r
+\r
+"It should matter everything to you, Mr. Gray."\r
+\r
+"Why?"\r
+\r
+"Because you have the most marvellous youth, and youth is the one thing\r
+worth having."\r
+\r
+"I don't feel that, Lord Henry."\r
+\r
+"No, you don't feel it now. Some day, when you are old and wrinkled\r
+and ugly, when thought has seared your forehead with its lines, and\r
+passion branded your lips with its hideous fires, you will feel it, you\r
+will feel it terribly. Now, wherever you go, you charm the world.\r
+Will it always be so? ... You have a wonderfully beautiful face, Mr.\r
+Gray. Don't frown. You have. And beauty is a form of genius--is\r
+higher, indeed, than genius, as it needs no explanation. It is of the\r
+great facts of the world, like sunlight, or spring-time, or the\r
+reflection in dark waters of that silver shell we call the moon. It\r
+cannot be questioned. It has its divine right of sovereignty. It\r
+makes princes of those who have it. You smile? Ah! when you have lost\r
+it you won't smile.... People say sometimes that beauty is only\r
+superficial. That may be so, but at least it is not so superficial as\r
+thought is. To me, beauty is the wonder of wonders. It is only\r
+shallow people who do not judge by appearances. The true mystery of\r
+the world is the visible, not the invisible.... Yes, Mr. Gray, the\r
+gods have been good to you. But what the gods give they quickly take\r
+away. You have only a few years in which to live really, perfectly,\r
+and fully. When your youth goes, your beauty will go with it, and then\r
+you will suddenly discover that there are no triumphs left for you, or\r
+have to content yourself with those mean triumphs that the memory of\r
+your past will make more bitter than defeats. Every month as it wanes\r
+brings you nearer to something dreadful. Time is jealous of you, and\r
+wars against your lilies and your roses. You will become sallow, and\r
+hollow-cheeked, and dull-eyed. You will suffer horribly.... Ah!\r
+realize your youth while you have it. Don't squander the gold of your\r
+days, listening to the tedious, trying to improve the hopeless failure,\r
+or giving away your life to the ignorant, the common, and the vulgar.\r
+These are the sickly aims, the false ideals, of our age. Live! Live\r
+the wonderful life that is in you! Let nothing be lost upon you. Be\r
+always searching for new sensations. Be afraid of nothing.... A new\r
+Hedonism--that is what our century wants. You might be its visible\r
+symbol. With your personality there is nothing you could not do. The\r
+world belongs to you for a season.... The moment I met you I saw that\r
+you were quite unconscious of what you really are, of what you really\r
+might be. There was so much in you that charmed me that I felt I must\r
+tell you something about yourself. I thought how tragic it would be if\r
+you were wasted. For there is such a little time that your youth will\r
+last--such a little time. The common hill-flowers wither, but they\r
+blossom again. The laburnum will be as yellow next June as it is now.\r
+In a month there will be purple stars on the clematis, and year after\r
+year the green night of its leaves will hold its purple stars. But we\r
+never get back our youth. The pulse of joy that beats in us at twenty\r
+becomes sluggish. Our limbs fail, our senses rot. We degenerate into\r
+hideous puppets, haunted by the memory of the passions of which we were\r
+too much afraid, and the exquisite temptations that we had not the\r
+courage to yield to. Youth! Youth! There is absolutely nothing in\r
+the world but youth!"\r
+\r
+Dorian Gray listened, open-eyed and wondering. The spray of lilac fell\r
+from his hand upon the gravel. A furry bee came and buzzed round it\r
+for a moment. Then it began to scramble all over the oval stellated\r
+globe of the tiny blossoms. He watched it with that strange interest\r
+in trivial things that we try to develop when things of high import\r
+make us afraid, or when we are stirred by some new emotion for which we\r
+cannot find expression, or when some thought that terrifies us lays\r
+sudden siege to the brain and calls on us to yield. After a time the\r
+bee flew away. He saw it creeping into the stained trumpet of a Tyrian\r
+convolvulus. The flower seemed to quiver, and then swayed gently to\r
+and fro.\r
+\r
+Suddenly the painter appeared at the door of the studio and made\r
+staccato signs for them to come in. They turned to each other and\r
+smiled.\r
+\r
+"I am waiting," he cried. "Do come in. The light is quite perfect,\r
+and you can bring your drinks."\r
+\r
+They rose up and sauntered down the walk together. Two green-and-white\r
+butterflies fluttered past them, and in the pear-tree at the corner of\r
+the garden a thrush began to sing.\r
+\r
+"You are glad you have met me, Mr. Gray," said Lord Henry, looking at\r
+him.\r
+\r
+"Yes, I am glad now. I wonder shall I always be glad?"\r
+\r
+"Always! That is a dreadful word. It makes me shudder when I hear it.\r
+Women are so fond of using it. They spoil every romance by trying to\r
+make it last for ever. It is a meaningless word, too. The only\r
+difference between a caprice and a lifelong passion is that the caprice\r
+lasts a little longer."\r
+\r
+As they entered the studio, Dorian Gray put his hand upon Lord Henry's\r
+arm. "In that case, let our friendship be a caprice," he murmured,\r
+flushing at his own boldness, then stepped up on the platform and\r
+resumed his pose.\r
+\r
+Lord Henry flung himself into a large wicker arm-chair and watched him.\r
+The sweep and dash of the brush on the canvas made the only sound that\r
+broke the stillness, except when, now and then, Hallward stepped back\r
+to look at his work from a distance. In the slanting beams that\r
+streamed through the open doorway the dust danced and was golden. The\r
+heavy scent of the roses seemed to brood over everything.\r
+\r
+After about a quarter of an hour Hallward stopped painting, looked for\r
+a long time at Dorian Gray, and then for a long time at the picture,\r
+biting the end of one of his huge brushes and frowning. "It is quite\r
+finished," he cried at last, and stooping down he wrote his name in\r
+long vermilion letters on the left-hand corner of the canvas.\r
+\r
+Lord Henry came over and examined the picture. It was certainly a\r
+wonderful work of art, and a wonderful likeness as well.\r
+\r
+"My dear fellow, I congratulate you most warmly," he said. "It is the\r
+finest portrait of modern times. Mr. Gray, come over and look at\r
+yourself."\r
+\r
+The lad started, as if awakened from some dream.\r
+\r
+"Is it really finished?" he murmured, stepping down from the platform.\r
+\r
+"Quite finished," said the painter. "And you have sat splendidly\r
+to-day. I am awfully obliged to you."\r
+\r
+"That is entirely due to me," broke in Lord Henry. "Isn't it, Mr.\r
+Gray?"\r
+\r
+Dorian made no answer, but passed listlessly in front of his picture\r
+and turned towards it. When he saw it he drew back, and his cheeks\r
+flushed for a moment with pleasure. A look of joy came into his eyes,\r
+as if he had recognized himself for the first time. He stood there\r
+motionless and in wonder, dimly conscious that Hallward was speaking to\r
+him, but not catching the meaning of his words. The sense of his own\r
+beauty came on him like a revelation. He had never felt it before.\r
+Basil Hallward's compliments had seemed to him to be merely the\r
+charming exaggeration of friendship. He had listened to them, laughed\r
+at them, forgotten them. They had not influenced his nature. Then had\r
+come Lord Henry Wotton with his strange panegyric on youth, his\r
+terrible warning of its brevity. That had stirred him at the time, and\r
+now, as he stood gazing at the shadow of his own loveliness, the full\r
+reality of the description flashed across him. Yes, there would be a\r
+day when his face would be wrinkled and wizen, his eyes dim and\r
+colourless, the grace of his figure broken and deformed. The scarlet\r
+would pass away from his lips and the gold steal from his hair. The\r
+life that was to make his soul would mar his body. He would become\r
+dreadful, hideous, and uncouth.\r
+\r
+As he thought of it, a sharp pang of pain struck through him like a\r
+knife and made each delicate fibre of his nature quiver. His eyes\r
+deepened into amethyst, and across them came a mist of tears. He felt\r
+as if a hand of ice had been laid upon his heart.\r
+\r
+"Don't you like it?" cried Hallward at last, stung a little by the\r
+lad's silence, not understanding what it meant.\r
+\r
+"Of course he likes it," said Lord Henry. "Who wouldn't like it? It\r
+is one of the greatest things in modern art. I will give you anything\r
+you like to ask for it. I must have it."\r
+\r
+"It is not my property, Harry."\r
+\r
+"Whose property is it?"\r
+\r
+"Dorian's, of course," answered the painter.\r
+\r
+"He is a very lucky fellow."\r
+\r
+"How sad it is!" murmured Dorian Gray with his eyes still fixed upon\r
+his own portrait. "How sad it is! I shall grow old, and horrible, and\r
+dreadful. But this picture will remain always young. It will never be\r
+older than this particular day of June.... If it were only the other\r
+way! If it were I who was to be always young, and the picture that was\r
+to grow old! For that--for that--I would give everything! Yes, there\r
+is nothing in the whole world I would not give! I would give my soul\r
+for that!"\r
+\r
+"You would hardly care for such an arrangement, Basil," cried Lord\r
+Henry, laughing. "It would be rather hard lines on your work."\r
+\r
+"I should object very strongly, Harry," said Hallward.\r
+\r
+Dorian Gray turned and looked at him. "I believe you would, Basil.\r
+You like your art better than your friends. I am no more to you than a\r
+green bronze figure. Hardly as much, I dare say."\r
+\r
+The painter stared in amazement. It was so unlike Dorian to speak like\r
+that. What had happened? He seemed quite angry. His face was flushed\r
+and his cheeks burning.\r
+\r
+"Yes," he continued, "I am less to you than your ivory Hermes or your\r
+silver Faun. You will like them always. How long will you like me?\r
+Till I have my first wrinkle, I suppose. I know, now, that when one\r
+loses one's good looks, whatever they may be, one loses everything.\r
+Your picture has taught me that. Lord Henry Wotton is perfectly right.\r
+Youth is the only thing worth having. When I find that I am growing\r
+old, I shall kill myself."\r
+\r
+Hallward turned pale and caught his hand. "Dorian! Dorian!" he cried,\r
+"don't talk like that. I have never had such a friend as you, and I\r
+shall never have such another. You are not jealous of material things,\r
+are you?--you who are finer than any of them!"\r
+\r
+"I am jealous of everything whose beauty does not die. I am jealous of\r
+the portrait you have painted of me. Why should it keep what I must\r
+lose? Every moment that passes takes something from me and gives\r
+something to it. Oh, if it were only the other way! If the picture\r
+could change, and I could be always what I am now! Why did you paint\r
+it? It will mock me some day--mock me horribly!" The hot tears welled\r
+into his eyes; he tore his hand away and, flinging himself on the\r
+divan, he buried his face in the cushions, as though he was praying.\r
+\r
+"This is your doing, Harry," said the painter bitterly.\r
+\r
+Lord Henry shrugged his shoulders. "It is the real Dorian Gray--that\r
+is all."\r
+\r
+"It is not."\r
+\r
+"If it is not, what have I to do with it?"\r
+\r
+"You should have gone away when I asked you," he muttered.\r
+\r
+"I stayed when you asked me," was Lord Henry's answer.\r
+\r
+"Harry, I can't quarrel with my two best friends at once, but between\r
+you both you have made me hate the finest piece of work I have ever\r
+done, and I will destroy it. What is it but canvas and colour? I will\r
+not let it come across our three lives and mar them."\r
+\r
+Dorian Gray lifted his golden head from the pillow, and with pallid\r
+face and tear-stained eyes, looked at him as he walked over to the deal\r
+painting-table that was set beneath the high curtained window. What\r
+was he doing there? His fingers were straying about among the litter\r
+of tin tubes and dry brushes, seeking for something. Yes, it was for\r
+the long palette-knife, with its thin blade of lithe steel. He had\r
+found it at last. He was going to rip up the canvas.\r
+\r
+With a stifled sob the lad leaped from the couch, and, rushing over to\r
+Hallward, tore the knife out of his hand, and flung it to the end of\r
+the studio. "Don't, Basil, don't!" he cried. "It would be murder!"\r
+\r
+"I am glad you appreciate my work at last, Dorian," said the painter\r
+coldly when he had recovered from his surprise. "I never thought you\r
+would."\r
+\r
+"Appreciate it? I am in love with it, Basil. It is part of myself. I\r
+feel that."\r
+\r
+"Well, as soon as you are dry, you shall be varnished, and framed, and\r
+sent home. Then you can do what you like with yourself." And he walked\r
+across the room and rang the bell for tea. "You will have tea, of\r
+course, Dorian? And so will you, Harry? Or do you object to such\r
+simple pleasures?"\r
+\r
+"I adore simple pleasures," said Lord Henry. "They are the last refuge\r
+of the complex. But I don't like scenes, except on the stage. What\r
+absurd fellows you are, both of you! I wonder who it was defined man\r
+as a rational animal. It was the most premature definition ever given.\r
+Man is many things, but he is not rational. I am glad he is not, after\r
+all--though I wish you chaps would not squabble over the picture. You\r
+had much better let me have it, Basil. This silly boy doesn't really\r
+want it, and I really do."\r
+\r
+"If you let any one have it but me, Basil, I shall never forgive you!"\r
+cried Dorian Gray; "and I don't allow people to call me a silly boy."\r
+\r
+"You know the picture is yours, Dorian. I gave it to you before it\r
+existed."\r
+\r
+"And you know you have been a little silly, Mr. Gray, and that you\r
+don't really object to being reminded that you are extremely young."\r
+\r
+"I should have objected very strongly this morning, Lord Henry."\r
+\r
+"Ah! this morning! You have lived since then."\r
+\r
+There came a knock at the door, and the butler entered with a laden\r
+tea-tray and set it down upon a small Japanese table. There was a\r
+rattle of cups and saucers and the hissing of a fluted Georgian urn.\r
+Two globe-shaped china dishes were brought in by a page. Dorian Gray\r
+went over and poured out the tea. The two men sauntered languidly to\r
+the table and examined what was under the covers.\r
+\r
+"Let us go to the theatre to-night," said Lord Henry. "There is sure\r
+to be something on, somewhere. I have promised to dine at White's, but\r
+it is only with an old friend, so I can send him a wire to say that I\r
+am ill, or that I am prevented from coming in consequence of a\r
+subsequent engagement. I think that would be a rather nice excuse: it\r
+would have all the surprise of candour."\r
+\r
+"It is such a bore putting on one's dress-clothes," muttered Hallward.\r
+"And, when one has them on, they are so horrid."\r
+\r
+"Yes," answered Lord Henry dreamily, "the costume of the nineteenth\r
+century is detestable. It is so sombre, so depressing. Sin is the\r
+only real colour-element left in modern life."\r
+\r
+"You really must not say things like that before Dorian, Harry."\r
+\r
+"Before which Dorian? The one who is pouring out tea for us, or the\r
+one in the picture?"\r
+\r
+"Before either."\r
+\r
+"I should like to come to the theatre with you, Lord Henry," said the\r
+lad.\r
+\r
+"Then you shall come; and you will come, too, Basil, won't you?"\r
+\r
+"I can't, really. I would sooner not. I have a lot of work to do."\r
+\r
+"Well, then, you and I will go alone, Mr. Gray."\r
+\r
+"I should like that awfully."\r
+\r
+The painter bit his lip and walked over, cup in hand, to the picture.\r
+"I shall stay with the real Dorian," he said, sadly.\r
+\r
+"Is it the real Dorian?" cried the original of the portrait, strolling\r
+across to him. "Am I really like that?"\r
+\r
+"Yes; you are just like that."\r
+\r
+"How wonderful, Basil!"\r
+\r
+"At least you are like it in appearance. But it will never alter,"\r
+sighed Hallward. "That is something."\r
+\r
+"What a fuss people make about fidelity!" exclaimed Lord Henry. "Why,\r
+even in love it is purely a question for physiology. It has nothing to\r
+do with our own will. Young men want to be faithful, and are not; old\r
+men want to be faithless, and cannot: that is all one can say."\r
+\r
+"Don't go to the theatre to-night, Dorian," said Hallward. "Stop and\r
+dine with me."\r
+\r
+"I can't, Basil."\r
+\r
+"Why?"\r
+\r
+"Because I have promised Lord Henry Wotton to go with him."\r
+\r
+"He won't like you the better for keeping your promises. He always\r
+breaks his own. I beg you not to go."\r
+\r
+Dorian Gray laughed and shook his head.\r
+\r
+"I entreat you."\r
+\r
+The lad hesitated, and looked over at Lord Henry, who was watching them\r
+from the tea-table with an amused smile.\r
+\r
+"I must go, Basil," he answered.\r
+\r
+"Very well," said Hallward, and he went over and laid down his cup on\r
+the tray. "It is rather late, and, as you have to dress, you had\r
+better lose no time. Good-bye, Harry. Good-bye, Dorian. Come and see\r
+me soon. Come to-morrow."\r
+\r
+"Certainly."\r
+\r
+"You won't forget?"\r
+\r
+"No, of course not," cried Dorian.\r
+\r
+"And ... Harry!"\r
+\r
+"Yes, Basil?"\r
+\r
+"Remember what I asked you, when we were in the garden this morning."\r
+\r
+"I have forgotten it."\r
+\r
+"I trust you."\r
+\r
+"I wish I could trust myself," said Lord Henry, laughing. "Come, Mr.\r
+Gray, my hansom is outside, and I can drop you at your own place.\r
+Good-bye, Basil. It has been a most interesting afternoon."\r
+\r
+As the door closed behind them, the painter flung himself down on a\r
+sofa, and a look of pain came into his face.\r
+\r
+\r
+\r
+CHAPTER 3\r
+\r
+At half-past twelve next day Lord Henry Wotton strolled from Curzon\r
+Street over to the Albany to call on his uncle, Lord Fermor, a genial\r
+if somewhat rough-mannered old bachelor, whom the outside world called\r
+selfish because it derived no particular benefit from him, but who was\r
+considered generous by Society as he fed the people who amused him.\r
+His father had been our ambassador at Madrid when Isabella was young\r
+and Prim unthought of, but had retired from the diplomatic service in a\r
+capricious moment of annoyance on not being offered the Embassy at\r
+Paris, a post to which he considered that he was fully entitled by\r
+reason of his birth, his indolence, the good English of his dispatches,\r
+and his inordinate passion for pleasure. The son, who had been his\r
+father's secretary, had resigned along with his chief, somewhat\r
+foolishly as was thought at the time, and on succeeding some months\r
+later to the title, had set himself to the serious study of the great\r
+aristocratic art of doing absolutely nothing. He had two large town\r
+houses, but preferred to live in chambers as it was less trouble, and\r
+took most of his meals at his club. He paid some attention to the\r
+management of his collieries in the Midland counties, excusing himself\r
+for this taint of industry on the ground that the one advantage of\r
+having coal was that it enabled a gentleman to afford the decency of\r
+burning wood on his own hearth. In politics he was a Tory, except when\r
+the Tories were in office, during which period he roundly abused them\r
+for being a pack of Radicals. He was a hero to his valet, who bullied\r
+him, and a terror to most of his relations, whom he bullied in turn.\r
+Only England could have produced him, and he always said that the\r
+country was going to the dogs. His principles were out of date, but\r
+there was a good deal to be said for his prejudices.\r
+\r
+When Lord Henry entered the room, he found his uncle sitting in a rough\r
+shooting-coat, smoking a cheroot and grumbling over _The Times_. "Well,\r
+Harry," said the old gentleman, "what brings you out so early? I\r
+thought you dandies never got up till two, and were not visible till\r
+five."\r
+\r
+"Pure family affection, I assure you, Uncle George. I want to get\r
+something out of you."\r
+\r
+"Money, I suppose," said Lord Fermor, making a wry face. "Well, sit\r
+down and tell me all about it. Young people, nowadays, imagine that\r
+money is everything."\r
+\r
+"Yes," murmured Lord Henry, settling his button-hole in his coat; "and\r
+when they grow older they know it. But I don't want money. It is only\r
+people who pay their bills who want that, Uncle George, and I never pay\r
+mine. Credit is the capital of a younger son, and one lives charmingly\r
+upon it. Besides, I always deal with Dartmoor's tradesmen, and\r
+consequently they never bother me. What I want is information: not\r
+useful information, of course; useless information."\r
+\r
+"Well, I can tell you anything that is in an English Blue Book, Harry,\r
+although those fellows nowadays write a lot of nonsense. When I was in\r
+the Diplomatic, things were much better. But I hear they let them in\r
+now by examination. What can you expect? Examinations, sir, are pure\r
+humbug from beginning to end. If a man is a gentleman, he knows quite\r
+enough, and if he is not a gentleman, whatever he knows is bad for him."\r
+\r
+"Mr. Dorian Gray does not belong to Blue Books, Uncle George," said\r
+Lord Henry languidly.\r
+\r
+"Mr. Dorian Gray? Who is he?" asked Lord Fermor, knitting his bushy\r
+white eyebrows.\r
+\r
+"That is what I have come to learn, Uncle George. Or rather, I know\r
+who he is. He is the last Lord Kelso's grandson. His mother was a\r
+Devereux, Lady Margaret Devereux. I want you to tell me about his\r
+mother. What was she like? Whom did she marry? You have known nearly\r
+everybody in your time, so you might have known her. I am very much\r
+interested in Mr. Gray at present. I have only just met him."\r
+\r
+"Kelso's grandson!" echoed the old gentleman. "Kelso's grandson! ...\r
+Of course.... I knew his mother intimately. I believe I was at her\r
+christening. She was an extraordinarily beautiful girl, Margaret\r
+Devereux, and made all the men frantic by running away with a penniless\r
+young fellow--a mere nobody, sir, a subaltern in a foot regiment, or\r
+something of that kind. Certainly. I remember the whole thing as if\r
+it happened yesterday. The poor chap was killed in a duel at Spa a few\r
+months after the marriage. There was an ugly story about it. They\r
+said Kelso got some rascally adventurer, some Belgian brute, to insult\r
+his son-in-law in public--paid him, sir, to do it, paid him--and that\r
+the fellow spitted his man as if he had been a pigeon. The thing was\r
+hushed up, but, egad, Kelso ate his chop alone at the club for some\r
+time afterwards. He brought his daughter back with him, I was told,\r
+and she never spoke to him again. Oh, yes; it was a bad business. The\r
+girl died, too, died within a year. So she left a son, did she? I had\r
+forgotten that. What sort of boy is he? If he is like his mother, he\r
+must be a good-looking chap."\r
+\r
+"He is very good-looking," assented Lord Henry.\r
+\r
+"I hope he will fall into proper hands," continued the old man. "He\r
+should have a pot of money waiting for him if Kelso did the right thing\r
+by him. His mother had money, too. All the Selby property came to\r
+her, through her grandfather. Her grandfather hated Kelso, thought him\r
+a mean dog. He was, too. Came to Madrid once when I was there. Egad,\r
+I was ashamed of him. The Queen used to ask me about the English noble\r
+who was always quarrelling with the cabmen about their fares. They\r
+made quite a story of it. I didn't dare show my face at Court for a\r
+month. I hope he treated his grandson better than he did the jarvies."\r
+\r
+"I don't know," answered Lord Henry. "I fancy that the boy will be\r
+well off. He is not of age yet. He has Selby, I know. He told me so.\r
+And ... his mother was very beautiful?"\r
+\r
+"Margaret Devereux was one of the loveliest creatures I ever saw,\r
+Harry. What on earth induced her to behave as she did, I never could\r
+understand. She could have married anybody she chose. Carlington was\r
+mad after her. She was romantic, though. All the women of that family\r
+were. The men were a poor lot, but, egad! the women were wonderful.\r
+Carlington went on his knees to her. Told me so himself. She laughed\r
+at him, and there wasn't a girl in London at the time who wasn't after\r
+him. And by the way, Harry, talking about silly marriages, what is\r
+this humbug your father tells me about Dartmoor wanting to marry an\r
+American? Ain't English girls good enough for him?"\r
+\r
+"It is rather fashionable to marry Americans just now, Uncle George."\r
+\r
+"I'll back English women against the world, Harry," said Lord Fermor,\r
+striking the table with his fist.\r
+\r
+"The betting is on the Americans."\r
+\r
+"They don't last, I am told," muttered his uncle.\r
+\r
+"A long engagement exhausts them, but they are capital at a\r
+steeplechase. They take things flying. I don't think Dartmoor has a\r
+chance."\r
+\r
+"Who are her people?" grumbled the old gentleman. "Has she got any?"\r
+\r
+Lord Henry shook his head. "American girls are as clever at concealing\r
+their parents, as English women are at concealing their past," he said,\r
+rising to go.\r
+\r
+"They are pork-packers, I suppose?"\r
+\r
+"I hope so, Uncle George, for Dartmoor's sake. I am told that\r
+pork-packing is the most lucrative profession in America, after\r
+politics."\r
+\r
+"Is she pretty?"\r
+\r
+"She behaves as if she was beautiful. Most American women do. It is\r
+the secret of their charm."\r
+\r
+"Why can't these American women stay in their own country? They are\r
+always telling us that it is the paradise for women."\r
+\r
+"It is. That is the reason why, like Eve, they are so excessively\r
+anxious to get out of it," said Lord Henry. "Good-bye, Uncle George.\r
+I shall be late for lunch, if I stop any longer. Thanks for giving me\r
+the information I wanted. I always like to know everything about my\r
+new friends, and nothing about my old ones."\r
+\r
+"Where are you lunching, Harry?"\r
+\r
+"At Aunt Agatha's. I have asked myself and Mr. Gray. He is her latest\r
+_protege_."\r
+\r
+"Humph! tell your Aunt Agatha, Harry, not to bother me any more with\r
+her charity appeals. I am sick of them. Why, the good woman thinks\r
+that I have nothing to do but to write cheques for her silly fads."\r
+\r
+"All right, Uncle George, I'll tell her, but it won't have any effect.\r
+Philanthropic people lose all sense of humanity. It is their\r
+distinguishing characteristic."\r
+\r
+The old gentleman growled approvingly and rang the bell for his\r
+servant. Lord Henry passed up the low arcade into Burlington Street\r
+and turned his steps in the direction of Berkeley Square.\r
+\r
+So that was the story of Dorian Gray's parentage. Crudely as it had\r
+been told to him, it had yet stirred him by its suggestion of a\r
+strange, almost modern romance. A beautiful woman risking everything\r
+for a mad passion. A few wild weeks of happiness cut short by a\r
+hideous, treacherous crime. Months of voiceless agony, and then a\r
+child born in pain. The mother snatched away by death, the boy left to\r
+solitude and the tyranny of an old and loveless man. Yes; it was an\r
+interesting background. It posed the lad, made him more perfect, as it\r
+were. Behind every exquisite thing that existed, there was something\r
+tragic. Worlds had to be in travail, that the meanest flower might\r
+blow.... And how charming he had been at dinner the night before, as\r
+with startled eyes and lips parted in frightened pleasure he had sat\r
+opposite to him at the club, the red candleshades staining to a richer\r
+rose the wakening wonder of his face. Talking to him was like playing\r
+upon an exquisite violin. He answered to every touch and thrill of the\r
+bow.... There was something terribly enthralling in the exercise of\r
+influence. No other activity was like it. To project one's soul into\r
+some gracious form, and let it tarry there for a moment; to hear one's\r
+own intellectual views echoed back to one with all the added music of\r
+passion and youth; to convey one's temperament into another as though\r
+it were a subtle fluid or a strange perfume: there was a real joy in\r
+that--perhaps the most satisfying joy left to us in an age so limited\r
+and vulgar as our own, an age grossly carnal in its pleasures, and\r
+grossly common in its aims.... He was a marvellous type, too, this lad,\r
+whom by so curious a chance he had met in Basil's studio, or could be\r
+fashioned into a marvellous type, at any rate. Grace was his, and the\r
+white purity of boyhood, and beauty such as old Greek marbles kept for\r
+us. There was nothing that one could not do with him. He could be\r
+made a Titan or a toy. What a pity it was that such beauty was\r
+destined to fade! ... And Basil? From a psychological point of view,\r
+how interesting he was! The new manner in art, the fresh mode of\r
+looking at life, suggested so strangely by the merely visible presence\r
+of one who was unconscious of it all; the silent spirit that dwelt in\r
+dim woodland, and walked unseen in open field, suddenly showing\r
+herself, Dryadlike and not afraid, because in his soul who sought for\r
+her there had been wakened that wonderful vision to which alone are\r
+wonderful things revealed; the mere shapes and patterns of things\r
+becoming, as it were, refined, and gaining a kind of symbolical value,\r
+as though they were themselves patterns of some other and more perfect\r
+form whose shadow they made real: how strange it all was! He\r
+remembered something like it in history. Was it not Plato, that artist\r
+in thought, who had first analyzed it? Was it not Buonarotti who had\r
+carved it in the coloured marbles of a sonnet-sequence? But in our own\r
+century it was strange.... Yes; he would try to be to Dorian Gray\r
+what, without knowing it, the lad was to the painter who had fashioned\r
+the wonderful portrait. He would seek to dominate him--had already,\r
+indeed, half done so. He would make that wonderful spirit his own.\r
+There was something fascinating in this son of love and death.\r
+\r
+Suddenly he stopped and glanced up at the houses. He found that he had\r
+passed his aunt's some distance, and, smiling to himself, turned back.\r
+When he entered the somewhat sombre hall, the butler told him that they\r
+had gone in to lunch. He gave one of the footmen his hat and stick and\r
+passed into the dining-room.\r
+\r
+"Late as usual, Harry," cried his aunt, shaking her head at him.\r
+\r
+He invented a facile excuse, and having taken the vacant seat next to\r
+her, looked round to see who was there. Dorian bowed to him shyly from\r
+the end of the table, a flush of pleasure stealing into his cheek.\r
+Opposite was the Duchess of Harley, a lady of admirable good-nature and\r
+good temper, much liked by every one who knew her, and of those ample\r
+architectural proportions that in women who are not duchesses are\r
+described by contemporary historians as stoutness. Next to her sat, on\r
+her right, Sir Thomas Burdon, a Radical member of Parliament, who\r
+followed his leader in public life and in private life followed the\r
+best cooks, dining with the Tories and thinking with the Liberals, in\r
+accordance with a wise and well-known rule. The post on her left was\r
+occupied by Mr. Erskine of Treadley, an old gentleman of considerable\r
+charm and culture, who had fallen, however, into bad habits of silence,\r
+having, as he explained once to Lady Agatha, said everything that he\r
+had to say before he was thirty. His own neighbour was Mrs. Vandeleur,\r
+one of his aunt's oldest friends, a perfect saint amongst women, but so\r
+dreadfully dowdy that she reminded one of a badly bound hymn-book.\r
+Fortunately for him she had on the other side Lord Faudel, a most\r
+intelligent middle-aged mediocrity, as bald as a ministerial statement\r
+in the House of Commons, with whom she was conversing in that intensely\r
+earnest manner which is the one unpardonable error, as he remarked once\r
+himself, that all really good people fall into, and from which none of\r
+them ever quite escape.\r
+\r
+"We are talking about poor Dartmoor, Lord Henry," cried the duchess,\r
+nodding pleasantly to him across the table. "Do you think he will\r
+really marry this fascinating young person?"\r
+\r
+"I believe she has made up her mind to propose to him, Duchess."\r
+\r
+"How dreadful!" exclaimed Lady Agatha. "Really, some one should\r
+interfere."\r
+\r
+"I am told, on excellent authority, that her father keeps an American\r
+dry-goods store," said Sir Thomas Burdon, looking supercilious.\r
+\r
+"My uncle has already suggested pork-packing, Sir Thomas."\r
+\r
+"Dry-goods! What are American dry-goods?" asked the duchess, raising\r
+her large hands in wonder and accentuating the verb.\r
+\r
+"American novels," answered Lord Henry, helping himself to some quail.\r
+\r
+The duchess looked puzzled.\r
+\r
+"Don't mind him, my dear," whispered Lady Agatha. "He never means\r
+anything that he says."\r
+\r
+"When America was discovered," said the Radical member--and he began to\r
+give some wearisome facts. Like all people who try to exhaust a\r
+subject, he exhausted his listeners. The duchess sighed and exercised\r
+her privilege of interruption. "I wish to goodness it never had been\r
+discovered at all!" she exclaimed. "Really, our girls have no chance\r
+nowadays. It is most unfair."\r
+\r
+"Perhaps, after all, America never has been discovered," said Mr.\r
+Erskine; "I myself would say that it had merely been detected."\r
+\r
+"Oh! but I have seen specimens of the inhabitants," answered the\r
+duchess vaguely. "I must confess that most of them are extremely\r
+pretty. And they dress well, too. They get all their dresses in\r
+Paris. I wish I could afford to do the same."\r
+\r
+"They say that when good Americans die they go to Paris," chuckled Sir\r
+Thomas, who had a large wardrobe of Humour's cast-off clothes.\r
+\r
+"Really! And where do bad Americans go to when they die?" inquired the\r
+duchess.\r
+\r
+"They go to America," murmured Lord Henry.\r
+\r
+Sir Thomas frowned. "I am afraid that your nephew is prejudiced\r
+against that great country," he said to Lady Agatha. "I have travelled\r
+all over it in cars provided by the directors, who, in such matters,\r
+are extremely civil. I assure you that it is an education to visit it."\r
+\r
+"But must we really see Chicago in order to be educated?" asked Mr.\r
+Erskine plaintively. "I don't feel up to the journey."\r
+\r
+Sir Thomas waved his hand. "Mr. Erskine of Treadley has the world on\r
+his shelves. We practical men like to see things, not to read about\r
+them. The Americans are an extremely interesting people. They are\r
+absolutely reasonable. I think that is their distinguishing\r
+characteristic. Yes, Mr. Erskine, an absolutely reasonable people. I\r
+assure you there is no nonsense about the Americans."\r
+\r
+"How dreadful!" cried Lord Henry. "I can stand brute force, but brute\r
+reason is quite unbearable. There is something unfair about its use.\r
+It is hitting below the intellect."\r
+\r
+"I do not understand you," said Sir Thomas, growing rather red.\r
+\r
+"I do, Lord Henry," murmured Mr. Erskine, with a smile.\r
+\r
+"Paradoxes are all very well in their way...." rejoined the baronet.\r
+\r
+"Was that a paradox?" asked Mr. Erskine. "I did not think so. Perhaps\r
+it was. Well, the way of paradoxes is the way of truth. To test\r
+reality we must see it on the tight rope. When the verities become\r
+acrobats, we can judge them."\r
+\r
+"Dear me!" said Lady Agatha, "how you men argue! I am sure I never can\r
+make out what you are talking about. Oh! Harry, I am quite vexed with\r
+you. Why do you try to persuade our nice Mr. Dorian Gray to give up\r
+the East End? I assure you he would be quite invaluable. They would\r
+love his playing."\r
+\r
+"I want him to play to me," cried Lord Henry, smiling, and he looked\r
+down the table and caught a bright answering glance.\r
+\r
+"But they are so unhappy in Whitechapel," continued Lady Agatha.\r
+\r
+"I can sympathize with everything except suffering," said Lord Henry,\r
+shrugging his shoulders. "I cannot sympathize with that. It is too\r
+ugly, too horrible, too distressing. There is something terribly\r
+morbid in the modern sympathy with pain. One should sympathize with\r
+the colour, the beauty, the joy of life. The less said about life's\r
+sores, the better."\r
+\r
+"Still, the East End is a very important problem," remarked Sir Thomas\r
+with a grave shake of the head.\r
+\r
+"Quite so," answered the young lord. "It is the problem of slavery,\r
+and we try to solve it by amusing the slaves."\r
+\r
+The politician looked at him keenly. "What change do you propose,\r
+then?" he asked.\r
+\r
+Lord Henry laughed. "I don't desire to change anything in England\r
+except the weather," he answered. "I am quite content with philosophic\r
+contemplation. But, as the nineteenth century has gone bankrupt\r
+through an over-expenditure of sympathy, I would suggest that we should\r
+appeal to science to put us straight. The advantage of the emotions is\r
+that they lead us astray, and the advantage of science is that it is\r
+not emotional."\r
+\r
+"But we have such grave responsibilities," ventured Mrs. Vandeleur\r
+timidly.\r
+\r
+"Terribly grave," echoed Lady Agatha.\r
+\r
+Lord Henry looked over at Mr. Erskine. "Humanity takes itself too\r
+seriously. It is the world's original sin. If the caveman had known\r
+how to laugh, history would have been different."\r
+\r
+"You are really very comforting," warbled the duchess. "I have always\r
+felt rather guilty when I came to see your dear aunt, for I take no\r
+interest at all in the East End. For the future I shall be able to\r
+look her in the face without a blush."\r
+\r
+"A blush is very becoming, Duchess," remarked Lord Henry.\r
+\r
+"Only when one is young," she answered. "When an old woman like myself\r
+blushes, it is a very bad sign. Ah! Lord Henry, I wish you would tell\r
+me how to become young again."\r
+\r
+He thought for a moment. "Can you remember any great error that you\r
+committed in your early days, Duchess?" he asked, looking at her across\r
+the table.\r
+\r
+"A great many, I fear," she cried.\r
+\r
+"Then commit them over again," he said gravely. "To get back one's\r
+youth, one has merely to repeat one's follies."\r
+\r
+"A delightful theory!" she exclaimed. "I must put it into practice."\r
+\r
+"A dangerous theory!" came from Sir Thomas's tight lips. Lady Agatha\r
+shook her head, but could not help being amused. Mr. Erskine listened.\r
+\r
+"Yes," he continued, "that is one of the great secrets of life.\r
+Nowadays most people die of a sort of creeping common sense, and\r
+discover when it is too late that the only things one never regrets are\r
+one's mistakes."\r
+\r
+A laugh ran round the table.\r
+\r
+He played with the idea and grew wilful; tossed it into the air and\r
+transformed it; let it escape and recaptured it; made it iridescent\r
+with fancy and winged it with paradox. The praise of folly, as he went\r
+on, soared into a philosophy, and philosophy herself became young, and\r
+catching the mad music of pleasure, wearing, one might fancy, her\r
+wine-stained robe and wreath of ivy, danced like a Bacchante over the\r
+hills of life, and mocked the slow Silenus for being sober. Facts fled\r
+before her like frightened forest things. Her white feet trod the huge\r
+press at which wise Omar sits, till the seething grape-juice rose round\r
+her bare limbs in waves of purple bubbles, or crawled in red foam over\r
+the vat's black, dripping, sloping sides. It was an extraordinary\r
+improvisation. He felt that the eyes of Dorian Gray were fixed on him,\r
+and the consciousness that amongst his audience there was one whose\r
+temperament he wished to fascinate seemed to give his wit keenness and\r
+to lend colour to his imagination. He was brilliant, fantastic,\r
+irresponsible. He charmed his listeners out of themselves, and they\r
+followed his pipe, laughing. Dorian Gray never took his gaze off him,\r
+but sat like one under a spell, smiles chasing each other over his lips\r
+and wonder growing grave in his darkening eyes.\r
+\r
+At last, liveried in the costume of the age, reality entered the room\r
+in the shape of a servant to tell the duchess that her carriage was\r
+waiting. She wrung her hands in mock despair. "How annoying!" she\r
+cried. "I must go. I have to call for my husband at the club, to take\r
+him to some absurd meeting at Willis's Rooms, where he is going to be\r
+in the chair. If I am late he is sure to be furious, and I couldn't\r
+have a scene in this bonnet. It is far too fragile. A harsh word\r
+would ruin it. No, I must go, dear Agatha. Good-bye, Lord Henry, you\r
+are quite delightful and dreadfully demoralizing. I am sure I don't\r
+know what to say about your views. You must come and dine with us some\r
+night. Tuesday? Are you disengaged Tuesday?"\r
+\r
+"For you I would throw over anybody, Duchess," said Lord Henry with a\r
+bow.\r
+\r
+"Ah! that is very nice, and very wrong of you," she cried; "so mind you\r
+come"; and she swept out of the room, followed by Lady Agatha and the\r
+other ladies.\r
+\r
+When Lord Henry had sat down again, Mr. Erskine moved round, and taking\r
+a chair close to him, placed his hand upon his arm.\r
+\r
+"You talk books away," he said; "why don't you write one?"\r
+\r
+"I am too fond of reading books to care to write them, Mr. Erskine. I\r
+should like to write a novel certainly, a novel that would be as lovely\r
+as a Persian carpet and as unreal. But there is no literary public in\r
+England for anything except newspapers, primers, and encyclopaedias.\r
+Of all people in the world the English have the least sense of the\r
+beauty of literature."\r
+\r
+"I fear you are right," answered Mr. Erskine. "I myself used to have\r
+literary ambitions, but I gave them up long ago. And now, my dear\r
+young friend, if you will allow me to call you so, may I ask if you\r
+really meant all that you said to us at lunch?"\r
+\r
+"I quite forget what I said," smiled Lord Henry. "Was it all very bad?"\r
+\r
+"Very bad indeed. In fact I consider you extremely dangerous, and if\r
+anything happens to our good duchess, we shall all look on you as being\r
+primarily responsible. But I should like to talk to you about life.\r
+The generation into which I was born was tedious. Some day, when you\r
+are tired of London, come down to Treadley and expound to me your\r
+philosophy of pleasure over some admirable Burgundy I am fortunate\r
+enough to possess."\r
+\r
+"I shall be charmed. A visit to Treadley would be a great privilege.\r
+It has a perfect host, and a perfect library."\r
+\r
+"You will complete it," answered the old gentleman with a courteous\r
+bow. "And now I must bid good-bye to your excellent aunt. I am due at\r
+the Athenaeum. It is the hour when we sleep there."\r
+\r
+"All of you, Mr. Erskine?"\r
+\r
+"Forty of us, in forty arm-chairs. We are practising for an English\r
+Academy of Letters."\r
+\r
+Lord Henry laughed and rose. "I am going to the park," he cried.\r
+\r
+As he was passing out of the door, Dorian Gray touched him on the arm.\r
+"Let me come with you," he murmured.\r
+\r
+"But I thought you had promised Basil Hallward to go and see him,"\r
+answered Lord Henry.\r
+\r
+"I would sooner come with you; yes, I feel I must come with you. Do\r
+let me. And you will promise to talk to me all the time? No one talks\r
+so wonderfully as you do."\r
+\r
+"Ah! I have talked quite enough for to-day," said Lord Henry, smiling.\r
+"All I want now is to look at life. You may come and look at it with\r
+me, if you care to."\r
+\r
+\r
+\r
+CHAPTER 4\r
+\r
+One afternoon, a month later, Dorian Gray was reclining in a luxurious\r
+arm-chair, in the little library of Lord Henry's house in Mayfair. It\r
+was, in its way, a very charming room, with its high panelled\r
+wainscoting of olive-stained oak, its cream-coloured frieze and ceiling\r
+of raised plasterwork, and its brickdust felt carpet strewn with silk,\r
+long-fringed Persian rugs. On a tiny satinwood table stood a statuette\r
+by Clodion, and beside it lay a copy of Les Cent Nouvelles, bound for\r
+Margaret of Valois by Clovis Eve and powdered with the gilt daisies\r
+that Queen had selected for her device. Some large blue china jars and\r
+parrot-tulips were ranged on the mantelshelf, and through the small\r
+leaded panes of the window streamed the apricot-coloured light of a\r
+summer day in London.\r
+\r
+Lord Henry had not yet come in. He was always late on principle, his\r
+principle being that punctuality is the thief of time. So the lad was\r
+looking rather sulky, as with listless fingers he turned over the pages\r
+of an elaborately illustrated edition of Manon Lescaut that he had\r
+found in one of the book-cases. The formal monotonous ticking of the\r
+Louis Quatorze clock annoyed him. Once or twice he thought of going\r
+away.\r
+\r
+At last he heard a step outside, and the door opened. "How late you\r
+are, Harry!" he murmured.\r
+\r
+"I am afraid it is not Harry, Mr. Gray," answered a shrill voice.\r
+\r
+He glanced quickly round and rose to his feet. "I beg your pardon. I\r
+thought--"\r
+\r
+"You thought it was my husband. It is only his wife. You must let me\r
+introduce myself. I know you quite well by your photographs. I think\r
+my husband has got seventeen of them."\r
+\r
+"Not seventeen, Lady Henry?"\r
+\r
+"Well, eighteen, then. And I saw you with him the other night at the\r
+opera." She laughed nervously as she spoke, and watched him with her\r
+vague forget-me-not eyes. She was a curious woman, whose dresses\r
+always looked as if they had been designed in a rage and put on in a\r
+tempest. She was usually in love with somebody, and, as her passion\r
+was never returned, she had kept all her illusions. She tried to look\r
+picturesque, but only succeeded in being untidy. Her name was\r
+Victoria, and she had a perfect mania for going to church.\r
+\r
+"That was at Lohengrin, Lady Henry, I think?"\r
+\r
+"Yes; it was at dear Lohengrin. I like Wagner's music better than\r
+anybody's. It is so loud that one can talk the whole time without other\r
+people hearing what one says. That is a great advantage, don't you\r
+think so, Mr. Gray?"\r
+\r
+The same nervous staccato laugh broke from her thin lips, and her\r
+fingers began to play with a long tortoise-shell paper-knife.\r
+\r
+Dorian smiled and shook his head: "I am afraid I don't think so, Lady\r
+Henry. I never talk during music--at least, during good music. If one\r
+hears bad music, it is one's duty to drown it in conversation."\r
+\r
+"Ah! that is one of Harry's views, isn't it, Mr. Gray? I always hear\r
+Harry's views from his friends. It is the only way I get to know of\r
+them. But you must not think I don't like good music. I adore it, but\r
+I am afraid of it. It makes me too romantic. I have simply worshipped\r
+pianists--two at a time, sometimes, Harry tells me. I don't know what\r
+it is about them. Perhaps it is that they are foreigners. They all\r
+are, ain't they? Even those that are born in England become foreigners\r
+after a time, don't they? It is so clever of them, and such a\r
+compliment to art. Makes it quite cosmopolitan, doesn't it? You have\r
+never been to any of my parties, have you, Mr. Gray? You must come. I\r
+can't afford orchids, but I spare no expense in foreigners. They make\r
+one's rooms look so picturesque. But here is Harry! Harry, I came in\r
+to look for you, to ask you something--I forget what it was--and I\r
+found Mr. Gray here. We have had such a pleasant chat about music. We\r
+have quite the same ideas. No; I think our ideas are quite different.\r
+But he has been most pleasant. I am so glad I've seen him."\r
+\r
+"I am charmed, my love, quite charmed," said Lord Henry, elevating his\r
+dark, crescent-shaped eyebrows and looking at them both with an amused\r
+smile. "So sorry I am late, Dorian. I went to look after a piece of\r
+old brocade in Wardour Street and had to bargain for hours for it.\r
+Nowadays people know the price of everything and the value of nothing."\r
+\r
+"I am afraid I must be going," exclaimed Lady Henry, breaking an\r
+awkward silence with her silly sudden laugh. "I have promised to drive\r
+with the duchess. Good-bye, Mr. Gray. Good-bye, Harry. You are\r
+dining out, I suppose? So am I. Perhaps I shall see you at Lady\r
+Thornbury's."\r
+\r
+"I dare say, my dear," said Lord Henry, shutting the door behind her\r
+as, looking like a bird of paradise that had been out all night in the\r
+rain, she flitted out of the room, leaving a faint odour of\r
+frangipanni. Then he lit a cigarette and flung himself down on the\r
+sofa.\r
+\r
+"Never marry a woman with straw-coloured hair, Dorian," he said after a\r
+few puffs.\r
+\r
+"Why, Harry?"\r
+\r
+"Because they are so sentimental."\r
+\r
+"But I like sentimental people."\r
+\r
+"Never marry at all, Dorian. Men marry because they are tired; women,\r
+because they are curious: both are disappointed."\r
+\r
+"I don't think I am likely to marry, Harry. I am too much in love.\r
+That is one of your aphorisms. I am putting it into practice, as I do\r
+everything that you say."\r
+\r
+"Who are you in love with?" asked Lord Henry after a pause.\r
+\r
+"With an actress," said Dorian Gray, blushing.\r
+\r
+Lord Henry shrugged his shoulders. "That is a rather commonplace\r
+_debut_."\r
+\r
+"You would not say so if you saw her, Harry."\r
+\r
+"Who is she?"\r
+\r
+"Her name is Sibyl Vane."\r
+\r
+"Never heard of her."\r
+\r
+"No one has. People will some day, however. She is a genius."\r
+\r
+"My dear boy, no woman is a genius. Women are a decorative sex. They\r
+never have anything to say, but they say it charmingly. Women\r
+represent the triumph of matter over mind, just as men represent the\r
+triumph of mind over morals."\r
+\r
+"Harry, how can you?"\r
+\r
+"My dear Dorian, it is quite true. I am analysing women at present, so\r
+I ought to know. The subject is not so abstruse as I thought it was.\r
+I find that, ultimately, there are only two kinds of women, the plain\r
+and the coloured. The plain women are very useful. If you want to\r
+gain a reputation for respectability, you have merely to take them down\r
+to supper. The other women are very charming. They commit one\r
+mistake, however. They paint in order to try and look young. Our\r
+grandmothers painted in order to try and talk brilliantly. _Rouge_ and\r
+_esprit_ used to go together. That is all over now. As long as a woman\r
+can look ten years younger than her own daughter, she is perfectly\r
+satisfied. As for conversation, there are only five women in London\r
+worth talking to, and two of these can't be admitted into decent\r
+society. However, tell me about your genius. How long have you known\r
+her?"\r
+\r
+"Ah! Harry, your views terrify me."\r
+\r
+"Never mind that. How long have you known her?"\r
+\r
+"About three weeks."\r
+\r
+"And where did you come across her?"\r
+\r
+"I will tell you, Harry, but you mustn't be unsympathetic about it.\r
+After all, it never would have happened if I had not met you. You\r
+filled me with a wild desire to know everything about life. For days\r
+after I met you, something seemed to throb in my veins. As I lounged\r
+in the park, or strolled down Piccadilly, I used to look at every one\r
+who passed me and wonder, with a mad curiosity, what sort of lives they\r
+led. Some of them fascinated me. Others filled me with terror. There\r
+was an exquisite poison in the air. I had a passion for sensations....\r
+Well, one evening about seven o'clock, I determined to go out in search\r
+of some adventure. I felt that this grey monstrous London of ours,\r
+with its myriads of people, its sordid sinners, and its splendid sins,\r
+as you once phrased it, must have something in store for me. I fancied\r
+a thousand things. The mere danger gave me a sense of delight. I\r
+remembered what you had said to me on that wonderful evening when we\r
+first dined together, about the search for beauty being the real secret\r
+of life. I don't know what I expected, but I went out and wandered\r
+eastward, soon losing my way in a labyrinth of grimy streets and black\r
+grassless squares. About half-past eight I passed by an absurd little\r
+theatre, with great flaring gas-jets and gaudy play-bills. A hideous\r
+Jew, in the most amazing waistcoat I ever beheld in my life, was\r
+standing at the entrance, smoking a vile cigar. He had greasy\r
+ringlets, and an enormous diamond blazed in the centre of a soiled\r
+shirt. 'Have a box, my Lord?' he said, when he saw me, and he took off\r
+his hat with an air of gorgeous servility. There was something about\r
+him, Harry, that amused me. He was such a monster. You will laugh at\r
+me, I know, but I really went in and paid a whole guinea for the\r
+stage-box. To the present day I can't make out why I did so; and yet if\r
+I hadn't--my dear Harry, if I hadn't--I should have missed the greatest\r
+romance of my life. I see you are laughing. It is horrid of you!"\r
+\r
+"I am not laughing, Dorian; at least I am not laughing at you. But you\r
+should not say the greatest romance of your life. You should say the\r
+first romance of your life. You will always be loved, and you will\r
+always be in love with love. A _grande passion_ is the privilege of\r
+people who have nothing to do. That is the one use of the idle classes\r
+of a country. Don't be afraid. There are exquisite things in store\r
+for you. This is merely the beginning."\r
+\r
+"Do you think my nature so shallow?" cried Dorian Gray angrily.\r
+\r
+"No; I think your nature so deep."\r
+\r
+"How do you mean?"\r
+\r
+"My dear boy, the people who love only once in their lives are really\r
+the shallow people. What they call their loyalty, and their fidelity,\r
+I call either the lethargy of custom or their lack of imagination.\r
+Faithfulness is to the emotional life what consistency is to the life\r
+of the intellect--simply a confession of failure. Faithfulness! I\r
+must analyse it some day. The passion for property is in it. There\r
+are many things that we would throw away if we were not afraid that\r
+others might pick them up. But I don't want to interrupt you. Go on\r
+with your story."\r
+\r
+"Well, I found myself seated in a horrid little private box, with a\r
+vulgar drop-scene staring me in the face. I looked out from behind the\r
+curtain and surveyed the house. It was a tawdry affair, all Cupids and\r
+cornucopias, like a third-rate wedding-cake. The gallery and pit were\r
+fairly full, but the two rows of dingy stalls were quite empty, and\r
+there was hardly a person in what I suppose they called the\r
+dress-circle. Women went about with oranges and ginger-beer, and there\r
+was a terrible consumption of nuts going on."\r
+\r
+"It must have been just like the palmy days of the British drama."\r
+\r
+"Just like, I should fancy, and very depressing. I began to wonder\r
+what on earth I should do when I caught sight of the play-bill. What\r
+do you think the play was, Harry?"\r
+\r
+"I should think 'The Idiot Boy', or 'Dumb but Innocent'. Our fathers\r
+used to like that sort of piece, I believe. The longer I live, Dorian,\r
+the more keenly I feel that whatever was good enough for our fathers is\r
+not good enough for us. In art, as in politics, _les grandperes ont\r
+toujours tort_."\r
+\r
+"This play was good enough for us, Harry. It was Romeo and Juliet. I\r
+must admit that I was rather annoyed at the idea of seeing Shakespeare\r
+done in such a wretched hole of a place. Still, I felt interested, in\r
+a sort of way. At any rate, I determined to wait for the first act.\r
+There was a dreadful orchestra, presided over by a young Hebrew who sat\r
+at a cracked piano, that nearly drove me away, but at last the\r
+drop-scene was drawn up and the play began. Romeo was a stout elderly\r
+gentleman, with corked eyebrows, a husky tragedy voice, and a figure\r
+like a beer-barrel. Mercutio was almost as bad. He was played by the\r
+low-comedian, who had introduced gags of his own and was on most\r
+friendly terms with the pit. They were both as grotesque as the\r
+scenery, and that looked as if it had come out of a country-booth. But\r
+Juliet! Harry, imagine a girl, hardly seventeen years of age, with a\r
+little, flowerlike face, a small Greek head with plaited coils of\r
+dark-brown hair, eyes that were violet wells of passion, lips that were\r
+like the petals of a rose. She was the loveliest thing I had ever seen\r
+in my life. You said to me once that pathos left you unmoved, but that\r
+beauty, mere beauty, could fill your eyes with tears. I tell you,\r
+Harry, I could hardly see this girl for the mist of tears that came\r
+across me. And her voice--I never heard such a voice. It was very low\r
+at first, with deep mellow notes that seemed to fall singly upon one's\r
+ear. Then it became a little louder, and sounded like a flute or a\r
+distant hautboy. In the garden-scene it had all the tremulous ecstasy\r
+that one hears just before dawn when nightingales are singing. There\r
+were moments, later on, when it had the wild passion of violins. You\r
+know how a voice can stir one. Your voice and the voice of Sibyl Vane\r
+are two things that I shall never forget. When I close my eyes, I hear\r
+them, and each of them says something different. I don't know which to\r
+follow. Why should I not love her? Harry, I do love her. She is\r
+everything to me in life. Night after night I go to see her play. One\r
+evening she is Rosalind, and the next evening she is Imogen. I have\r
+seen her die in the gloom of an Italian tomb, sucking the poison from\r
+her lover's lips. I have watched her wandering through the forest of\r
+Arden, disguised as a pretty boy in hose and doublet and dainty cap.\r
+She has been mad, and has come into the presence of a guilty king, and\r
+given him rue to wear and bitter herbs to taste of. She has been\r
+innocent, and the black hands of jealousy have crushed her reedlike\r
+throat. I have seen her in every age and in every costume. Ordinary\r
+women never appeal to one's imagination. They are limited to their\r
+century. No glamour ever transfigures them. One knows their minds as\r
+easily as one knows their bonnets. One can always find them. There is\r
+no mystery in any of them. They ride in the park in the morning and\r
+chatter at tea-parties in the afternoon. They have their stereotyped\r
+smile and their fashionable manner. They are quite obvious. But an\r
+actress! How different an actress is! Harry! why didn't you tell me\r
+that the only thing worth loving is an actress?"\r
+\r
+"Because I have loved so many of them, Dorian."\r
+\r
+"Oh, yes, horrid people with dyed hair and painted faces."\r
+\r
+"Don't run down dyed hair and painted faces. There is an extraordinary\r
+charm in them, sometimes," said Lord Henry.\r
+\r
+"I wish now I had not told you about Sibyl Vane."\r
+\r
+"You could not have helped telling me, Dorian. All through your life\r
+you will tell me everything you do."\r
+\r
+"Yes, Harry, I believe that is true. I cannot help telling you things.\r
+You have a curious influence over me. If I ever did a crime, I would\r
+come and confess it to you. You would understand me."\r
+\r
+"People like you--the wilful sunbeams of life--don't commit crimes,\r
+Dorian. But I am much obliged for the compliment, all the same. And\r
+now tell me--reach me the matches, like a good boy--thanks--what are\r
+your actual relations with Sibyl Vane?"\r
+\r
+Dorian Gray leaped to his feet, with flushed cheeks and burning eyes.\r
+"Harry! Sibyl Vane is sacred!"\r
+\r
+"It is only the sacred things that are worth touching, Dorian," said\r
+Lord Henry, with a strange touch of pathos in his voice. "But why\r
+should you be annoyed? I suppose she will belong to you some day.\r
+When one is in love, one always begins by deceiving one's self, and one\r
+always ends by deceiving others. That is what the world calls a\r
+romance. You know her, at any rate, I suppose?"\r
+\r
+"Of course I know her. On the first night I was at the theatre, the\r
+horrid old Jew came round to the box after the performance was over and\r
+offered to take me behind the scenes and introduce me to her. I was\r
+furious with him, and told him that Juliet had been dead for hundreds\r
+of years and that her body was lying in a marble tomb in Verona. I\r
+think, from his blank look of amazement, that he was under the\r
+impression that I had taken too much champagne, or something."\r
+\r
+"I am not surprised."\r
+\r
+"Then he asked me if I wrote for any of the newspapers. I told him I\r
+never even read them. He seemed terribly disappointed at that, and\r
+confided to me that all the dramatic critics were in a conspiracy\r
+against him, and that they were every one of them to be bought."\r
+\r
+"I should not wonder if he was quite right there. But, on the other\r
+hand, judging from their appearance, most of them cannot be at all\r
+expensive."\r
+\r
+"Well, he seemed to think they were beyond his means," laughed Dorian.\r
+"By this time, however, the lights were being put out in the theatre,\r
+and I had to go. He wanted me to try some cigars that he strongly\r
+recommended. I declined. The next night, of course, I arrived at the\r
+place again. When he saw me, he made me a low bow and assured me that\r
+I was a munificent patron of art. He was a most offensive brute,\r
+though he had an extraordinary passion for Shakespeare. He told me\r
+once, with an air of pride, that his five bankruptcies were entirely\r
+due to 'The Bard,' as he insisted on calling him. He seemed to think\r
+it a distinction."\r
+\r
+"It was a distinction, my dear Dorian--a great distinction. Most\r
+people become bankrupt through having invested too heavily in the prose\r
+of life. To have ruined one's self over poetry is an honour. But when\r
+did you first speak to Miss Sibyl Vane?"\r
+\r
+"The third night. She had been playing Rosalind. I could not help\r
+going round. I had thrown her some flowers, and she had looked at\r
+me--at least I fancied that she had. The old Jew was persistent. He\r
+seemed determined to take me behind, so I consented. It was curious my\r
+not wanting to know her, wasn't it?"\r
+\r
+"No; I don't think so."\r
+\r
+"My dear Harry, why?"\r
+\r
+"I will tell you some other time. Now I want to know about the girl."\r
+\r
+"Sibyl? Oh, she was so shy and so gentle. There is something of a\r
+child about her. Her eyes opened wide in exquisite wonder when I told\r
+her what I thought of her performance, and she seemed quite unconscious\r
+of her power. I think we were both rather nervous. The old Jew stood\r
+grinning at the doorway of the dusty greenroom, making elaborate\r
+speeches about us both, while we stood looking at each other like\r
+children. He would insist on calling me 'My Lord,' so I had to assure\r
+Sibyl that I was not anything of the kind. She said quite simply to\r
+me, 'You look more like a prince. I must call you Prince Charming.'"\r
+\r
+"Upon my word, Dorian, Miss Sibyl knows how to pay compliments."\r
+\r
+"You don't understand her, Harry. She regarded me merely as a person\r
+in a play. She knows nothing of life. She lives with her mother, a\r
+faded tired woman who played Lady Capulet in a sort of magenta\r
+dressing-wrapper on the first night, and looks as if she had seen\r
+better days."\r
+\r
+"I know that look. It depresses me," murmured Lord Henry, examining\r
+his rings.\r
+\r
+"The Jew wanted to tell me her history, but I said it did not interest\r
+me."\r
+\r
+"You were quite right. There is always something infinitely mean about\r
+other people's tragedies."\r
+\r
+"Sibyl is the only thing I care about. What is it to me where she came\r
+from? From her little head to her little feet, she is absolutely and\r
+entirely divine. Every night of my life I go to see her act, and every\r
+night she is more marvellous."\r
+\r
+"That is the reason, I suppose, that you never dine with me now. I\r
+thought you must have some curious romance on hand. You have; but it\r
+is not quite what I expected."\r
+\r
+"My dear Harry, we either lunch or sup together every day, and I have\r
+been to the opera with you several times," said Dorian, opening his\r
+blue eyes in wonder.\r
+\r
+"You always come dreadfully late."\r
+\r
+"Well, I can't help going to see Sibyl play," he cried, "even if it is\r
+only for a single act. I get hungry for her presence; and when I think\r
+of the wonderful soul that is hidden away in that little ivory body, I\r
+am filled with awe."\r
+\r
+"You can dine with me to-night, Dorian, can't you?"\r
+\r
+He shook his head. "To-night she is Imogen," he answered, "and\r
+to-morrow night she will be Juliet."\r
+\r
+"When is she Sibyl Vane?"\r
+\r
+"Never."\r
+\r
+"I congratulate you."\r
+\r
+"How horrid you are! She is all the great heroines of the world in\r
+one. She is more than an individual. You laugh, but I tell you she\r
+has genius. I love her, and I must make her love me. You, who know\r
+all the secrets of life, tell me how to charm Sibyl Vane to love me! I\r
+want to make Romeo jealous. I want the dead lovers of the world to\r
+hear our laughter and grow sad. I want a breath of our passion to stir\r
+their dust into consciousness, to wake their ashes into pain. My God,\r
+Harry, how I worship her!" He was walking up and down the room as he\r
+spoke. Hectic spots of red burned on his cheeks. He was terribly\r
+excited.\r
+\r
+Lord Henry watched him with a subtle sense of pleasure. How different\r
+he was now from the shy frightened boy he had met in Basil Hallward's\r
+studio! His nature had developed like a flower, had borne blossoms of\r
+scarlet flame. Out of its secret hiding-place had crept his soul, and\r
+desire had come to meet it on the way.\r
+\r
+"And what do you propose to do?" said Lord Henry at last.\r
+\r
+"I want you and Basil to come with me some night and see her act. I\r
+have not the slightest fear of the result. You are certain to\r
+acknowledge her genius. Then we must get her out of the Jew's hands.\r
+She is bound to him for three years--at least for two years and eight\r
+months--from the present time. I shall have to pay him something, of\r
+course. When all that is settled, I shall take a West End theatre and\r
+bring her out properly. She will make the world as mad as she has made\r
+me."\r
+\r
+"That would be impossible, my dear boy."\r
+\r
+"Yes, she will. She has not merely art, consummate art-instinct, in\r
+her, but she has personality also; and you have often told me that it\r
+is personalities, not principles, that move the age."\r
+\r
+"Well, what night shall we go?"\r
+\r
+"Let me see. To-day is Tuesday. Let us fix to-morrow. She plays\r
+Juliet to-morrow."\r
+\r
+"All right. The Bristol at eight o'clock; and I will get Basil."\r
+\r
+"Not eight, Harry, please. Half-past six. We must be there before the\r
+curtain rises. You must see her in the first act, where she meets\r
+Romeo."\r
+\r
+"Half-past six! What an hour! It will be like having a meat-tea, or\r
+reading an English novel. It must be seven. No gentleman dines before\r
+seven. Shall you see Basil between this and then? Or shall I write to\r
+him?"\r
+\r
+"Dear Basil! I have not laid eyes on him for a week. It is rather\r
+horrid of me, as he has sent me my portrait in the most wonderful\r
+frame, specially designed by himself, and, though I am a little jealous\r
+of the picture for being a whole month younger than I am, I must admit\r
+that I delight in it. Perhaps you had better write to him. I don't\r
+want to see him alone. He says things that annoy me. He gives me good\r
+advice."\r
+\r
+Lord Henry smiled. "People are very fond of giving away what they need\r
+most themselves. It is what I call the depth of generosity."\r
+\r
+"Oh, Basil is the best of fellows, but he seems to me to be just a bit\r
+of a Philistine. Since I have known you, Harry, I have discovered\r
+that."\r
+\r
+"Basil, my dear boy, puts everything that is charming in him into his\r
+work. The consequence is that he has nothing left for life but his\r
+prejudices, his principles, and his common sense. The only artists I\r
+have ever known who are personally delightful are bad artists. Good\r
+artists exist simply in what they make, and consequently are perfectly\r
+uninteresting in what they are. A great poet, a really great poet, is\r
+the most unpoetical of all creatures. But inferior poets are\r
+absolutely fascinating. The worse their rhymes are, the more\r
+picturesque they look. The mere fact of having published a book of\r
+second-rate sonnets makes a man quite irresistible. He lives the\r
+poetry that he cannot write. The others write the poetry that they\r
+dare not realize."\r
+\r
+"I wonder is that really so, Harry?" said Dorian Gray, putting some\r
+perfume on his handkerchief out of a large, gold-topped bottle that\r
+stood on the table. "It must be, if you say it. And now I am off.\r
+Imogen is waiting for me. Don't forget about to-morrow. Good-bye."\r
+\r
+As he left the room, Lord Henry's heavy eyelids drooped, and he began\r
+to think. Certainly few people had ever interested him so much as\r
+Dorian Gray, and yet the lad's mad adoration of some one else caused\r
+him not the slightest pang of annoyance or jealousy. He was pleased by\r
+it. It made him a more interesting study. He had been always\r
+enthralled by the methods of natural science, but the ordinary\r
+subject-matter of that science had seemed to him trivial and of no\r
+import. And so he had begun by vivisecting himself, as he had ended by\r
+vivisecting others. Human life--that appeared to him the one thing\r
+worth investigating. Compared to it there was nothing else of any\r
+value. It was true that as one watched life in its curious crucible of\r
+pain and pleasure, one could not wear over one's face a mask of glass,\r
+nor keep the sulphurous fumes from troubling the brain and making the\r
+imagination turbid with monstrous fancies and misshapen dreams. There\r
+were poisons so subtle that to know their properties one had to sicken\r
+of them. There were maladies so strange that one had to pass through\r
+them if one sought to understand their nature. And, yet, what a great\r
+reward one received! How wonderful the whole world became to one! To\r
+note the curious hard logic of passion, and the emotional coloured life\r
+of the intellect--to observe where they met, and where they separated,\r
+at what point they were in unison, and at what point they were at\r
+discord--there was a delight in that! What matter what the cost was?\r
+One could never pay too high a price for any sensation.\r
+\r
+He was conscious--and the thought brought a gleam of pleasure into his\r
+brown agate eyes--that it was through certain words of his, musical\r
+words said with musical utterance, that Dorian Gray's soul had turned\r
+to this white girl and bowed in worship before her. To a large extent\r
+the lad was his own creation. He had made him premature. That was\r
+something. Ordinary people waited till life disclosed to them its\r
+secrets, but to the few, to the elect, the mysteries of life were\r
+revealed before the veil was drawn away. Sometimes this was the effect\r
+of art, and chiefly of the art of literature, which dealt immediately\r
+with the passions and the intellect. But now and then a complex\r
+personality took the place and assumed the office of art, was indeed,\r
+in its way, a real work of art, life having its elaborate masterpieces,\r
+just as poetry has, or sculpture, or painting.\r
+\r
+Yes, the lad was premature. He was gathering his harvest while it was\r
+yet spring. The pulse and passion of youth were in him, but he was\r
+becoming self-conscious. It was delightful to watch him. With his\r
+beautiful face, and his beautiful soul, he was a thing to wonder at.\r
+It was no matter how it all ended, or was destined to end. He was like\r
+one of those gracious figures in a pageant or a play, whose joys seem\r
+to be remote from one, but whose sorrows stir one's sense of beauty,\r
+and whose wounds are like red roses.\r
+\r
+Soul and body, body and soul--how mysterious they were! There was\r
+animalism in the soul, and the body had its moments of spirituality.\r
+The senses could refine, and the intellect could degrade. Who could\r
+say where the fleshly impulse ceased, or the psychical impulse began?\r
+How shallow were the arbitrary definitions of ordinary psychologists!\r
+And yet how difficult to decide between the claims of the various\r
+schools! Was the soul a shadow seated in the house of sin? Or was the\r
+body really in the soul, as Giordano Bruno thought? The separation of\r
+spirit from matter was a mystery, and the union of spirit with matter\r
+was a mystery also.\r
+\r
+He began to wonder whether we could ever make psychology so absolute a\r
+science that each little spring of life would be revealed to us. As it\r
+was, we always misunderstood ourselves and rarely understood others.\r
+Experience was of no ethical value. It was merely the name men gave to\r
+their mistakes. Moralists had, as a rule, regarded it as a mode of\r
+warning, had claimed for it a certain ethical efficacy in the formation\r
+of character, had praised it as something that taught us what to follow\r
+and showed us what to avoid. But there was no motive power in\r
+experience. It was as little of an active cause as conscience itself.\r
+All that it really demonstrated was that our future would be the same\r
+as our past, and that the sin we had done once, and with loathing, we\r
+would do many times, and with joy.\r
+\r
+It was clear to him that the experimental method was the only method by\r
+which one could arrive at any scientific analysis of the passions; and\r
+certainly Dorian Gray was a subject made to his hand, and seemed to\r
+promise rich and fruitful results. His sudden mad love for Sibyl Vane\r
+was a psychological phenomenon of no small interest. There was no\r
+doubt that curiosity had much to do with it, curiosity and the desire\r
+for new experiences, yet it was not a simple, but rather a very complex\r
+passion. What there was in it of the purely sensuous instinct of\r
+boyhood had been transformed by the workings of the imagination,\r
+changed into something that seemed to the lad himself to be remote from\r
+sense, and was for that very reason all the more dangerous. It was the\r
+passions about whose origin we deceived ourselves that tyrannized most\r
+strongly over us. Our weakest motives were those of whose nature we\r
+were conscious. It often happened that when we thought we were\r
+experimenting on others we were really experimenting on ourselves.\r
+\r
+While Lord Henry sat dreaming on these things, a knock came to the\r
+door, and his valet entered and reminded him it was time to dress for\r
+dinner. He got up and looked out into the street. The sunset had\r
+smitten into scarlet gold the upper windows of the houses opposite.\r
+The panes glowed like plates of heated metal. The sky above was like a\r
+faded rose. He thought of his friend's young fiery-coloured life and\r
+wondered how it was all going to end.\r

+When he arrived home, about half-past twelve o'clock, he saw a telegram\r
+lying on the hall table. He opened it and found it was from Dorian\r
+Gray. It was to tell him that he was engaged to be married to Sibyl\r
+Vane.\r
+\r
+\r
+\r
+CHAPTER 5\r
+\r
+"Mother, Mother, I am so happy!" whispered the girl, burying her face\r
+in the lap of the faded, tired-looking woman who, with back turned to\r
+the shrill intrusive light, was sitting in the one arm-chair that their\r
+dingy sitting-room contained. "I am so happy!" she repeated, "and you\r
+must be happy, too!"\r
+\r
+Mrs. Vane winced and put her thin, bismuth-whitened hands on her\r
+daughter's head. "Happy!" she echoed, "I am only happy, Sibyl, when I\r
+see you act. You must not think of anything but your acting. Mr.\r
+Isaacs has been very good to us, and we owe him money."\r
+\r
+The girl looked up and pouted. "Money, Mother?" she cried, "what does\r
+money matter? Love is more than money."\r
+\r
+"Mr. Isaacs has advanced us fifty pounds to pay off our debts and to\r
+get a proper outfit for James. You must not forget that, Sibyl. Fifty\r
+pounds is a very large sum. Mr. Isaacs has been most considerate."\r
+\r
+"He is not a gentleman, Mother, and I hate the way he talks to me,"\r
+said the girl, rising to her feet and going over to the window.\r
+\r
+"I don't know how we could manage without him," answered the elder\r
+woman querulously.\r
+\r
+Sibyl Vane tossed her head and laughed. "We don't want him any more,\r
+Mother. Prince Charming rules life for us now." Then she paused. A\r
+rose shook in her blood and shadowed her cheeks. Quick breath parted\r
+the petals of her lips. They trembled. Some southern wind of passion\r
+swept over her and stirred the dainty folds of her dress. "I love\r
+him," she said simply.\r
+\r
+"Foolish child! foolish child!" was the parrot-phrase flung in answer.\r
+The waving of crooked, false-jewelled fingers gave grotesqueness to the\r
+words.\r
+\r
+The girl laughed again. The joy of a caged bird was in her voice. Her\r
+eyes caught the melody and echoed it in radiance, then closed for a\r
+moment, as though to hide their secret. When they opened, the mist of\r
+a dream had passed across them.\r
+\r
+Thin-lipped wisdom spoke at her from the worn chair, hinted at\r
+prudence, quoted from that book of cowardice whose author apes the name\r
+of common sense. She did not listen. She was free in her prison of\r
+passion. Her prince, Prince Charming, was with her. She had called on\r
+memory to remake him. She had sent her soul to search for him, and it\r
+had brought him back. His kiss burned again upon her mouth. Her\r
+eyelids were warm with his breath.\r
+\r
+Then wisdom altered its method and spoke of espial and discovery. This\r
+young man might be rich. If so, marriage should be thought of.\r
+Against the shell of her ear broke the waves of worldly cunning. The\r
+arrows of craft shot by her. She saw the thin lips moving, and smiled.\r
+\r
+Suddenly she felt the need to speak. The wordy silence troubled her.\r
+"Mother, Mother," she cried, "why does he love me so much? I know why\r
+I love him. I love him because he is like what love himself should be.\r
+But what does he see in me? I am not worthy of him. And yet--why, I\r
+cannot tell--though I feel so much beneath him, I don't feel humble. I\r
+feel proud, terribly proud. Mother, did you love my father as I love\r
+Prince Charming?"\r
+\r
+The elder woman grew pale beneath the coarse powder that daubed her\r
+cheeks, and her dry lips twitched with a spasm of pain. Sybil rushed\r
+to her, flung her arms round her neck, and kissed her. "Forgive me,\r
+Mother. I know it pains you to talk about our father. But it only\r
+pains you because you loved him so much. Don't look so sad. I am as\r
+happy to-day as you were twenty years ago. Ah! let me be happy for\r
+ever!"\r
+\r
+"My child, you are far too young to think of falling in love. Besides,\r
+what do you know of this young man? You don't even know his name. The\r
+whole thing is most inconvenient, and really, when James is going away\r
+to Australia, and I have so much to think of, I must say that you\r
+should have shown more consideration. However, as I said before, if he\r
+is rich ..."\r
+\r
+"Ah! Mother, Mother, let me be happy!"\r
+\r
+Mrs. Vane glanced at her, and with one of those false theatrical\r
+gestures that so often become a mode of second nature to a\r
+stage-player, clasped her in her arms. At this moment, the door opened\r
+and a young lad with rough brown hair came into the room. He was\r
+thick-set of figure, and his hands and feet were large and somewhat\r
+clumsy in movement. He was not so finely bred as his sister. One\r
+would hardly have guessed the close relationship that existed between\r
+them. Mrs. Vane fixed her eyes on him and intensified her smile. She\r
+mentally elevated her son to the dignity of an audience. She felt sure\r
+that the _tableau_ was interesting.\r
+\r
+"You might keep some of your kisses for me, Sibyl, I think," said the\r
+lad with a good-natured grumble.\r
+\r
+"Ah! but you don't like being kissed, Jim," she cried. "You are a\r
+dreadful old bear." And she ran across the room and hugged him.\r
+\r
+James Vane looked into his sister's face with tenderness. "I want you\r
+to come out with me for a walk, Sibyl. I don't suppose I shall ever\r
+see this horrid London again. I am sure I don't want to."\r
+\r
+"My son, don't say such dreadful things," murmured Mrs. Vane, taking up\r
+a tawdry theatrical dress, with a sigh, and beginning to patch it. She\r
+felt a little disappointed that he had not joined the group. It would\r
+have increased the theatrical picturesqueness of the situation.\r
+\r
+"Why not, Mother? I mean it."\r
+\r
+"You pain me, my son. I trust you will return from Australia in a\r
+position of affluence. I believe there is no society of any kind in\r
+the Colonies--nothing that I would call society--so when you have made\r
+your fortune, you must come back and assert yourself in London."\r
+\r
+"Society!" muttered the lad. "I don't want to know anything about\r
+that. I should like to make some money to take you and Sibyl off the\r
+stage. I hate it."\r
+\r
+"Oh, Jim!" said Sibyl, laughing, "how unkind of you! But are you\r
+really going for a walk with me? That will be nice! I was afraid you\r
+were going to say good-bye to some of your friends--to Tom Hardy, who\r
+gave you that hideous pipe, or Ned Langton, who makes fun of you for\r
+smoking it. It is very sweet of you to let me have your last\r
+afternoon. Where shall we go? Let us go to the park."\r
+\r
+"I am too shabby," he answered, frowning. "Only swell people go to the\r
+park."\r
+\r
+"Nonsense, Jim," she whispered, stroking the sleeve of his coat.\r
+\r
+He hesitated for a moment. "Very well," he said at last, "but don't be\r
+too long dressing." She danced out of the door. One could hear her\r
+singing as she ran upstairs. Her little feet pattered overhead.\r
+\r
+He walked up and down the room two or three times. Then he turned to\r
+the still figure in the chair. "Mother, are my things ready?" he asked.\r
+\r
+"Quite ready, James," she answered, keeping her eyes on her work. For\r
+some months past she had felt ill at ease when she was alone with this\r
+rough stern son of hers. Her shallow secret nature was troubled when\r
+their eyes met. She used to wonder if he suspected anything. The\r
+silence, for he made no other observation, became intolerable to her.\r
+She began to complain. Women defend themselves by attacking, just as\r
+they attack by sudden and strange surrenders. "I hope you will be\r
+contented, James, with your sea-faring life," she said. "You must\r
+remember that it is your own choice. You might have entered a\r
+solicitor's office. Solicitors are a very respectable class, and in\r
+the country often dine with the best families."\r
+\r
+"I hate offices, and I hate clerks," he replied. "But you are quite\r
+right. I have chosen my own life. All I say is, watch over Sibyl.\r
+Don't let her come to any harm. Mother, you must watch over her."\r
+\r
+"James, you really talk very strangely. Of course I watch over Sibyl."\r
+\r
+"I hear a gentleman comes every night to the theatre and goes behind to\r
+talk to her. Is that right? What about that?"\r
+\r
+"You are speaking about things you don't understand, James. In the\r
+profession we are accustomed to receive a great deal of most gratifying\r
+attention. I myself used to receive many bouquets at one time. That\r
+was when acting was really understood. As for Sibyl, I do not know at\r
+present whether her attachment is serious or not. But there is no\r
+doubt that the young man in question is a perfect gentleman. He is\r
+always most polite to me. Besides, he has the appearance of being\r
+rich, and the flowers he sends are lovely."\r
+\r
+"You don't know his name, though," said the lad harshly.\r
+\r
+"No," answered his mother with a placid expression in her face. "He\r
+has not yet revealed his real name. I think it is quite romantic of\r
+him. He is probably a member of the aristocracy."\r
+\r
+James Vane bit his lip. "Watch over Sibyl, Mother," he cried, "watch\r
+over her."\r
+\r
+"My son, you distress me very much. Sibyl is always under my special\r
+care. Of course, if this gentleman is wealthy, there is no reason why\r
+she should not contract an alliance with him. I trust he is one of the\r
+aristocracy. He has all the appearance of it, I must say. It might be\r
+a most brilliant marriage for Sibyl. They would make a charming\r
+couple. His good looks are really quite remarkable; everybody notices\r
+them."\r
+\r
+The lad muttered something to himself and drummed on the window-pane\r
+with his coarse fingers. He had just turned round to say something\r
+when the door opened and Sibyl ran in.\r
+\r
+"How serious you both are!" she cried. "What is the matter?"\r
+\r
+"Nothing," he answered. "I suppose one must be serious sometimes.\r
+Good-bye, Mother; I will have my dinner at five o'clock. Everything is\r
+packed, except my shirts, so you need not trouble."\r
+\r
+"Good-bye, my son," she answered with a bow of strained stateliness.\r
+\r
+She was extremely annoyed at the tone he had adopted with her, and\r
+there was something in his look that had made her feel afraid.\r
+\r
+"Kiss me, Mother," said the girl. Her flowerlike lips touched the\r
+withered cheek and warmed its frost.\r
+\r
+"My child! my child!" cried Mrs. Vane, looking up to the ceiling in\r
+search of an imaginary gallery.\r
+\r
+"Come, Sibyl," said her brother impatiently. He hated his mother's\r
+affectations.\r
+\r
+They went out into the flickering, wind-blown sunlight and strolled\r
+down the dreary Euston Road. The passersby glanced in wonder at the\r
+sullen heavy youth who, in coarse, ill-fitting clothes, was in the\r
+company of such a graceful, refined-looking girl. He was like a common\r
+gardener walking with a rose.\r
+\r
+Jim frowned from time to time when he caught the inquisitive glance of\r
+some stranger. He had that dislike of being stared at, which comes on\r
+geniuses late in life and never leaves the commonplace. Sibyl,\r
+however, was quite unconscious of the effect she was producing. Her\r
+love was trembling in laughter on her lips. She was thinking of Prince\r
+Charming, and, that she might think of him all the more, she did not\r
+talk of him, but prattled on about the ship in which Jim was going to\r
+sail, about the gold he was certain to find, about the wonderful\r
+heiress whose life he was to save from the wicked, red-shirted\r
+bushrangers. For he was not to remain a sailor, or a supercargo, or\r
+whatever he was going to be. Oh, no! A sailor's existence was\r
+dreadful. Fancy being cooped up in a horrid ship, with the hoarse,\r
+hump-backed waves trying to get in, and a black wind blowing the masts\r
+down and tearing the sails into long screaming ribands! He was to\r
+leave the vessel at Melbourne, bid a polite good-bye to the captain,\r
+and go off at once to the gold-fields. Before a week was over he was to\r
+come across a large nugget of pure gold, the largest nugget that had\r
+ever been discovered, and bring it down to the coast in a waggon\r
+guarded by six mounted policemen. The bushrangers were to attack them\r
+three times, and be defeated with immense slaughter. Or, no. He was\r
+not to go to the gold-fields at all. They were horrid places, where\r
+men got intoxicated, and shot each other in bar-rooms, and used bad\r
+language. He was to be a nice sheep-farmer, and one evening, as he was\r
+riding home, he was to see the beautiful heiress being carried off by a\r
+robber on a black horse, and give chase, and rescue her. Of course,\r
+she would fall in love with him, and he with her, and they would get\r
+married, and come home, and live in an immense house in London. Yes,\r
+there were delightful things in store for him. But he must be very\r
+good, and not lose his temper, or spend his money foolishly. She was\r
+only a year older than he was, but she knew so much more of life. He\r
+must be sure, also, to write to her by every mail, and to say his\r
+prayers each night before he went to sleep. God was very good, and\r
+would watch over him. She would pray for him, too, and in a few years\r
+he would come back quite rich and happy.\r
+\r
+The lad listened sulkily to her and made no answer. He was heart-sick\r
+at leaving home.\r
+\r
+Yet it was not this alone that made him gloomy and morose.\r
+Inexperienced though he was, he had still a strong sense of the danger\r
+of Sibyl's position. This young dandy who was making love to her could\r
+mean her no good. He was a gentleman, and he hated him for that, hated\r
+him through some curious race-instinct for which he could not account,\r
+and which for that reason was all the more dominant within him. He was\r
+conscious also of the shallowness and vanity of his mother's nature,\r
+and in that saw infinite peril for Sibyl and Sibyl's happiness.\r
+Children begin by loving their parents; as they grow older they judge\r
+them; sometimes they forgive them.\r
+\r
+His mother! He had something on his mind to ask of her, something that\r
+he had brooded on for many months of silence. A chance phrase that he\r
+had heard at the theatre, a whispered sneer that had reached his ears\r
+one night as he waited at the stage-door, had set loose a train of\r
+horrible thoughts. He remembered it as if it had been the lash of a\r
+hunting-crop across his face. His brows knit together into a wedge-like\r
+furrow, and with a twitch of pain he bit his underlip.\r
+\r
+"You are not listening to a word I am saying, Jim," cried Sibyl, "and I\r
+am making the most delightful plans for your future. Do say something."\r
+\r
+"What do you want me to say?"\r
+\r
+"Oh! that you will be a good boy and not forget us," she answered,\r
+smiling at him.\r
+\r
+He shrugged his shoulders. "You are more likely to forget me than I am\r
+to forget you, Sibyl."\r
+\r
+She flushed. "What do you mean, Jim?" she asked.\r
+\r
+"You have a new friend, I hear. Who is he? Why have you not told me\r
+about him? He means you no good."\r
+\r
+"Stop, Jim!" she exclaimed. "You must not say anything against him. I\r
+love him."\r
+\r
+"Why, you don't even know his name," answered the lad. "Who is he? I\r
+have a right to know."\r
+\r
+"He is called Prince Charming. Don't you like the name. Oh! you silly\r
+boy! you should never forget it. If you only saw him, you would think\r
+him the most wonderful person in the world. Some day you will meet\r
+him--when you come back from Australia. You will like him so much.\r
+Everybody likes him, and I ... love him. I wish you could come to the\r
+theatre to-night. He is going to be there, and I am to play Juliet.\r
+Oh! how I shall play it! Fancy, Jim, to be in love and play Juliet!\r
+To have him sitting there! To play for his delight! I am afraid I may\r
+frighten the company, frighten or enthrall them. To be in love is to\r
+surpass one's self. Poor dreadful Mr. Isaacs will be shouting 'genius'\r
+to his loafers at the bar. He has preached me as a dogma; to-night he\r
+will announce me as a revelation. I feel it. And it is all his, his\r
+only, Prince Charming, my wonderful lover, my god of graces. But I am\r
+poor beside him. Poor? What does that matter? When poverty creeps in\r
+at the door, love flies in through the window. Our proverbs want\r
+rewriting. They were made in winter, and it is summer now; spring-time\r
+for me, I think, a very dance of blossoms in blue skies."\r
+\r
+"He is a gentleman," said the lad sullenly.\r
+\r
+"A prince!" she cried musically. "What more do you want?"\r
+\r
+"He wants to enslave you."\r
+\r
+"I shudder at the thought of being free."\r
+\r
+"I want you to beware of him."\r
+\r
+"To see him is to worship him; to know him is to trust him."\r
+\r
+"Sibyl, you are mad about him."\r
+\r
+She laughed and took his arm. "You dear old Jim, you talk as if you\r
+were a hundred. Some day you will be in love yourself. Then you will\r
+know what it is. Don't look so sulky. Surely you should be glad to\r
+think that, though you are going away, you leave me happier than I have\r
+ever been before. Life has been hard for us both, terribly hard and\r
+difficult. But it will be different now. You are going to a new\r
+world, and I have found one. Here are two chairs; let us sit down and\r
+see the smart people go by."\r
+\r
+They took their seats amidst a crowd of watchers. The tulip-beds\r
+across the road flamed like throbbing rings of fire. A white\r
+dust--tremulous cloud of orris-root it seemed--hung in the panting air.\r
+The brightly coloured parasols danced and dipped like monstrous\r
+butterflies.\r
+\r
+She made her brother talk of himself, his hopes, his prospects. He\r
+spoke slowly and with effort. They passed words to each other as\r
+players at a game pass counters. Sibyl felt oppressed. She could not\r
+communicate her joy. A faint smile curving that sullen mouth was all\r
+the echo she could win. After some time she became silent. Suddenly\r
+she caught a glimpse of golden hair and laughing lips, and in an open\r
+carriage with two ladies Dorian Gray drove past.\r
+\r
+She started to her feet. "There he is!" she cried.\r
+\r
+"Who?" said Jim Vane.\r
+\r
+"Prince Charming," she answered, looking after the victoria.\r
+\r
+He jumped up and seized her roughly by the arm. "Show him to me.\r
+Which is he? Point him out. I must see him!" he exclaimed; but at\r
+that moment the Duke of Berwick's four-in-hand came between, and when\r
+it had left the space clear, the carriage had swept out of the park.\r
+\r
+"He is gone," murmured Sibyl sadly. "I wish you had seen him."\r
+\r
+"I wish I had, for as sure as there is a God in heaven, if he ever does\r
+you any wrong, I shall kill him."\r
+\r
+She looked at him in horror. He repeated his words. They cut the air\r
+like a dagger. The people round began to gape. A lady standing close\r
+to her tittered.\r
+\r
+"Come away, Jim; come away," she whispered. He followed her doggedly\r
+as she passed through the crowd. He felt glad at what he had said.\r
+\r
+When they reached the Achilles Statue, she turned round. There was\r
+pity in her eyes that became laughter on her lips. She shook her head\r
+at him. "You are foolish, Jim, utterly foolish; a bad-tempered boy,\r
+that is all. How can you say such horrible things? You don't know\r
+what you are talking about. You are simply jealous and unkind. Ah! I\r
+wish you would fall in love. Love makes people good, and what you said\r
+was wicked."\r
+\r
+"I am sixteen," he answered, "and I know what I am about. Mother is no\r
+help to you. She doesn't understand how to look after you. I wish now\r
+that I was not going to Australia at all. I have a great mind to chuck\r
+the whole thing up. I would, if my articles hadn't been signed."\r
+\r
+"Oh, don't be so serious, Jim. You are like one of the heroes of those\r
+silly melodramas Mother used to be so fond of acting in. I am not\r
+going to quarrel with you. I have seen him, and oh! to see him is\r
+perfect happiness. We won't quarrel. I know you would never harm any\r
+one I love, would you?"\r
+\r
+"Not as long as you love him, I suppose," was the sullen answer.\r
+\r
+"I shall love him for ever!" she cried.\r
+\r
+"And he?"\r
+\r
+"For ever, too!"\r
+\r
+"He had better."\r
+\r
+She shrank from him. Then she laughed and put her hand on his arm. He\r
+was merely a boy.\r
+\r
+At the Marble Arch they hailed an omnibus, which left them close to\r
+their shabby home in the Euston Road. It was after five o'clock, and\r
+Sibyl had to lie down for a couple of hours before acting. Jim\r
+insisted that she should do so. He said that he would sooner part with\r
+her when their mother was not present. She would be sure to make a\r
+scene, and he detested scenes of every kind.\r
+\r
+In Sybil's own room they parted. There was jealousy in the lad's\r
+heart, and a fierce murderous hatred of the stranger who, as it seemed\r
+to him, had come between them. Yet, when her arms were flung round his\r
+neck, and her fingers strayed through his hair, he softened and kissed\r
+her with real affection. There were tears in his eyes as he went\r
+downstairs.\r
+\r
+His mother was waiting for him below. She grumbled at his\r
+unpunctuality, as he entered. He made no answer, but sat down to his\r
+meagre meal. The flies buzzed round the table and crawled over the\r
+stained cloth. Through the rumble of omnibuses, and the clatter of\r
+street-cabs, he could hear the droning voice devouring each minute that\r
+was left to him.\r
+\r
+After some time, he thrust away his plate and put his head in his\r
+hands. He felt that he had a right to know. It should have been told\r
+to him before, if it was as he suspected. Leaden with fear, his mother\r
+watched him. Words dropped mechanically from her lips. A tattered\r
+lace handkerchief twitched in her fingers. When the clock struck six,\r
+he got up and went to the door. Then he turned back and looked at her.\r
+Their eyes met. In hers he saw a wild appeal for mercy. It enraged\r
+him.\r
+\r
+"Mother, I have something to ask you," he said. Her eyes wandered\r
+vaguely about the room. She made no answer. "Tell me the truth. I\r
+have a right to know. Were you married to my father?"\r
+\r
+She heaved a deep sigh. It was a sigh of relief. The terrible moment,\r
+the moment that night and day, for weeks and months, she had dreaded,\r
+had come at last, and yet she felt no terror. Indeed, in some measure\r
+it was a disappointment to her. The vulgar directness of the question\r
+called for a direct answer. The situation had not been gradually led\r
+up to. It was crude. It reminded her of a bad rehearsal.\r
+\r
+"No," she answered, wondering at the harsh simplicity of life.\r
+\r
+"My father was a scoundrel then!" cried the lad, clenching his fists.\r
+\r
+She shook her head. "I knew he was not free. We loved each other very\r
+much. If he had lived, he would have made provision for us. Don't\r
+speak against him, my son. He was your father, and a gentleman.\r
+Indeed, he was highly connected."\r
+\r
+An oath broke from his lips. "I don't care for myself," he exclaimed,\r
+"but don't let Sibyl.... It is a gentleman, isn't it, who is in love\r
+with her, or says he is? Highly connected, too, I suppose."\r
+\r
+For a moment a hideous sense of humiliation came over the woman. Her\r
+head drooped. She wiped her eyes with shaking hands. "Sibyl has a\r
+mother," she murmured; "I had none."\r
+\r
+The lad was touched. He went towards her, and stooping down, he kissed\r
+her. "I am sorry if I have pained you by asking about my father," he\r
+said, "but I could not help it. I must go now. Good-bye. Don't forget\r
+that you will have only one child now to look after, and believe me\r
+that if this man wrongs my sister, I will find out who he is, track him\r
+down, and kill him like a dog. I swear it."\r
+\r
+The exaggerated folly of the threat, the passionate gesture that\r
+accompanied it, the mad melodramatic words, made life seem more vivid\r
+to her. She was familiar with the atmosphere. She breathed more\r
+freely, and for the first time for many months she really admired her\r
+son. She would have liked to have continued the scene on the same\r
+emotional scale, but he cut her short. Trunks had to be carried down\r
+and mufflers looked for. The lodging-house drudge bustled in and out.\r
+There was the bargaining with the cabman. The moment was lost in\r
+vulgar details. It was with a renewed feeling of disappointment that\r
+she waved the tattered lace handkerchief from the window, as her son\r
+drove away. She was conscious that a great opportunity had been\r
+wasted. She consoled herself by telling Sibyl how desolate she felt\r
+her life would be, now that she had only one child to look after. She\r
+remembered the phrase. It had pleased her. Of the threat she said\r
+nothing. It was vividly and dramatically expressed. She felt that\r
+they would all laugh at it some day.\r
+\r
+\r
+\r
+CHAPTER 6\r
+\r
+"I suppose you have heard the news, Basil?" said Lord Henry that\r
+evening as Hallward was shown into a little private room at the Bristol\r
+where dinner had been laid for three.\r
+\r
+"No, Harry," answered the artist, giving his hat and coat to the bowing\r
+waiter. "What is it? Nothing about politics, I hope! They don't\r
+interest me. There is hardly a single person in the House of Commons\r
+worth painting, though many of them would be the better for a little\r
+whitewashing."\r
+\r
+"Dorian Gray is engaged to be married," said Lord Henry, watching him\r
+as he spoke.\r
+\r
+Hallward started and then frowned. "Dorian engaged to be married!" he\r
+cried. "Impossible!"\r
+\r
+"It is perfectly true."\r
+\r
+"To whom?"\r
+\r
+"To some little actress or other."\r
+\r
+"I can't believe it. Dorian is far too sensible."\r
+\r
+"Dorian is far too wise not to do foolish things now and then, my dear\r
+Basil."\r
+\r
+"Marriage is hardly a thing that one can do now and then, Harry."\r
+\r
+"Except in America," rejoined Lord Henry languidly. "But I didn't say\r
+he was married. I said he was engaged to be married. There is a great\r
+difference. I have a distinct remembrance of being married, but I have\r
+no recollection at all of being engaged. I am inclined to think that I\r
+never was engaged."\r
+\r
+"But think of Dorian's birth, and position, and wealth. It would be\r
+absurd for him to marry so much beneath him."\r
+\r
+"If you want to make him marry this girl, tell him that, Basil. He is\r
+sure to do it, then. Whenever a man does a thoroughly stupid thing, it\r
+is always from the noblest motives."\r
+\r
+"I hope the girl is good, Harry. I don't want to see Dorian tied to\r
+some vile creature, who might degrade his nature and ruin his\r
+intellect."\r
+\r
+"Oh, she is better than good--she is beautiful," murmured Lord Henry,\r
+sipping a glass of vermouth and orange-bitters. "Dorian says she is\r
+beautiful, and he is not often wrong about things of that kind. Your\r
+portrait of him has quickened his appreciation of the personal\r
+appearance of other people. It has had that excellent effect, amongst\r
+others. We are to see her to-night, if that boy doesn't forget his\r
+appointment."\r
+\r
+"Are you serious?"\r
+\r
+"Quite serious, Basil. I should be miserable if I thought I should\r
+ever be more serious than I am at the present moment."\r
+\r
+"But do you approve of it, Harry?" asked the painter, walking up and\r
+down the room and biting his lip. "You can't approve of it, possibly.\r
+It is some silly infatuation."\r
+\r
+"I never approve, or disapprove, of anything now. It is an absurd\r
+attitude to take towards life. We are not sent into the world to air\r
+our moral prejudices. I never take any notice of what common people\r
+say, and I never interfere with what charming people do. If a\r
+personality fascinates me, whatever mode of expression that personality\r
+selects is absolutely delightful to me. Dorian Gray falls in love with\r
+a beautiful girl who acts Juliet, and proposes to marry her. Why not?\r
+If he wedded Messalina, he would be none the less interesting. You\r
+know I am not a champion of marriage. The real drawback to marriage is\r
+that it makes one unselfish. And unselfish people are colourless.\r
+They lack individuality. Still, there are certain temperaments that\r
+marriage makes more complex. They retain their egotism, and add to it\r
+many other egos. They are forced to have more than one life. They\r
+become more highly organized, and to be highly organized is, I should\r
+fancy, the object of man's existence. Besides, every experience is of\r
+value, and whatever one may say against marriage, it is certainly an\r
+experience. I hope that Dorian Gray will make this girl his wife,\r
+passionately adore her for six months, and then suddenly become\r
+fascinated by some one else. He would be a wonderful study."\r
+\r
+"You don't mean a single word of all that, Harry; you know you don't.\r
+If Dorian Gray's life were spoiled, no one would be sorrier than\r
+yourself. You are much better than you pretend to be."\r
+\r
+Lord Henry laughed. "The reason we all like to think so well of others\r
+is that we are all afraid for ourselves. The basis of optimism is\r
+sheer terror. We think that we are generous because we credit our\r
+neighbour with the possession of those virtues that are likely to be a\r
+benefit to us. We praise the banker that we may overdraw our account,\r
+and find good qualities in the highwayman in the hope that he may spare\r
+our pockets. I mean everything that I have said. I have the greatest\r
+contempt for optimism. As for a spoiled life, no life is spoiled but\r
+one whose growth is arrested. If you want to mar a nature, you have\r
+merely to reform it. As for marriage, of course that would be silly,\r
+but there are other and more interesting bonds between men and women.\r
+I will certainly encourage them. They have the charm of being\r
+fashionable. But here is Dorian himself. He will tell you more than I\r
+can."\r
+\r
+"My dear Harry, my dear Basil, you must both congratulate me!" said the\r
+lad, throwing off his evening cape with its satin-lined wings and\r
+shaking each of his friends by the hand in turn. "I have never been so\r
+happy. Of course, it is sudden--all really delightful things are. And\r
+yet it seems to me to be the one thing I have been looking for all my\r
+life." He was flushed with excitement and pleasure, and looked\r
+extraordinarily handsome.\r
+\r
+"I hope you will always be very happy, Dorian," said Hallward, "but I\r
+don't quite forgive you for not having let me know of your engagement.\r
+You let Harry know."\r
+\r
+"And I don't forgive you for being late for dinner," broke in Lord\r
+Henry, putting his hand on the lad's shoulder and smiling as he spoke.\r
+"Come, let us sit down and try what the new _chef_ here is like, and then\r
+you will tell us how it all came about."\r
+\r
+"There is really not much to tell," cried Dorian as they took their\r
+seats at the small round table. "What happened was simply this. After\r
+I left you yesterday evening, Harry, I dressed, had some dinner at that\r
+little Italian restaurant in Rupert Street you introduced me to, and\r
+went down at eight o'clock to the theatre. Sibyl was playing Rosalind.\r
+Of course, the scenery was dreadful and the Orlando absurd. But Sibyl!\r
+You should have seen her! When she came on in her boy's clothes, she\r
+was perfectly wonderful. She wore a moss-coloured velvet jerkin with\r
+cinnamon sleeves, slim, brown, cross-gartered hose, a dainty little\r
+green cap with a hawk's feather caught in a jewel, and a hooded cloak\r
+lined with dull red. She had never seemed to me more exquisite. She\r
+had all the delicate grace of that Tanagra figurine that you have in\r
+your studio, Basil. Her hair clustered round her face like dark leaves\r
+round a pale rose. As for her acting--well, you shall see her\r
+to-night. She is simply a born artist. I sat in the dingy box\r
+absolutely enthralled. I forgot that I was in London and in the\r
+nineteenth century. I was away with my love in a forest that no man\r
+had ever seen. After the performance was over, I went behind and spoke\r
+to her. As we were sitting together, suddenly there came into her eyes\r
+a look that I had never seen there before. My lips moved towards hers.\r
+We kissed each other. I can't describe to you what I felt at that\r
+moment. It seemed to me that all my life had been narrowed to one\r
+perfect point of rose-coloured joy. She trembled all over and shook\r
+like a white narcissus. Then she flung herself on her knees and kissed\r
+my hands. I feel that I should not tell you all this, but I can't help\r
+it. Of course, our engagement is a dead secret. She has not even told\r
+her own mother. I don't know what my guardians will say. Lord Radley\r
+is sure to be furious. I don't care. I shall be of age in less than a\r
+year, and then I can do what I like. I have been right, Basil, haven't\r
+I, to take my love out of poetry and to find my wife in Shakespeare's\r
+plays? Lips that Shakespeare taught to speak have whispered their\r
+secret in my ear. I have had the arms of Rosalind around me, and\r
+kissed Juliet on the mouth."\r
+\r
+"Yes, Dorian, I suppose you were right," said Hallward slowly.\r
+\r
+"Have you seen her to-day?" asked Lord Henry.\r
+\r
+Dorian Gray shook his head. "I left her in the forest of Arden; I\r
+shall find her in an orchard in Verona."\r
+\r
+Lord Henry sipped his champagne in a meditative manner. "At what\r
+particular point did you mention the word marriage, Dorian? And what\r
+did she say in answer? Perhaps you forgot all about it."\r
+\r
+"My dear Harry, I did not treat it as a business transaction, and I did\r
+not make any formal proposal. I told her that I loved her, and she\r
+said she was not worthy to be my wife. Not worthy! Why, the whole\r
+world is nothing to me compared with her."\r
+\r
+"Women are wonderfully practical," murmured Lord Henry, "much more\r
+practical than we are. In situations of that kind we often forget to\r
+say anything about marriage, and they always remind us."\r
+\r
+Hallward laid his hand upon his arm. "Don't, Harry. You have annoyed\r
+Dorian. He is not like other men. He would never bring misery upon\r
+any one. His nature is too fine for that."\r
+\r
+Lord Henry looked across the table. "Dorian is never annoyed with me,"\r
+he answered. "I asked the question for the best reason possible, for\r
+the only reason, indeed, that excuses one for asking any\r
+question--simple curiosity. I have a theory that it is always the\r
+women who propose to us, and not we who propose to the women. Except,\r
+of course, in middle-class life. But then the middle classes are not\r
+modern."\r
+\r
+Dorian Gray laughed, and tossed his head. "You are quite incorrigible,\r
+Harry; but I don't mind. It is impossible to be angry with you. When\r
+you see Sibyl Vane, you will feel that the man who could wrong her\r
+would be a beast, a beast without a heart. I cannot understand how any\r
+one can wish to shame the thing he loves. I love Sibyl Vane. I want\r
+to place her on a pedestal of gold and to see the world worship the\r
+woman who is mine. What is marriage? An irrevocable vow. You mock at\r
+it for that. Ah! don't mock. It is an irrevocable vow that I want to\r
+take. Her trust makes me faithful, her belief makes me good. When I\r
+am with her, I regret all that you have taught me. I become different\r
+from what you have known me to be. I am changed, and the mere touch of\r
+Sibyl Vane's hand makes me forget you and all your wrong, fascinating,\r
+poisonous, delightful theories."\r
+\r
+"And those are ...?" asked Lord Henry, helping himself to some salad.\r
+\r
+"Oh, your theories about life, your theories about love, your theories\r
+about pleasure. All your theories, in fact, Harry."\r
+\r
+"Pleasure is the only thing worth having a theory about," he answered\r
+in his slow melodious voice. "But I am afraid I cannot claim my theory\r
+as my own. It belongs to Nature, not to me. Pleasure is Nature's\r
+test, her sign of approval. When we are happy, we are always good, but\r
+when we are good, we are not always happy."\r
+\r
+"Ah! but what do you mean by good?" cried Basil Hallward.\r
+\r
+"Yes," echoed Dorian, leaning back in his chair and looking at Lord\r
+Henry over the heavy clusters of purple-lipped irises that stood in the\r
+centre of the table, "what do you mean by good, Harry?"\r
+\r
+"To be good is to be in harmony with one's self," he replied, touching\r
+the thin stem of his glass with his pale, fine-pointed fingers.\r
+"Discord is to be forced to be in harmony with others. One's own\r
+life--that is the important thing. As for the lives of one's\r
+neighbours, if one wishes to be a prig or a Puritan, one can flaunt\r
+one's moral views about them, but they are not one's concern. Besides,\r
+individualism has really the higher aim. Modern morality consists in\r
+accepting the standard of one's age. I consider that for any man of\r
+culture to accept the standard of his age is a form of the grossest\r
+immorality."\r
+\r
+"But, surely, if one lives merely for one's self, Harry, one pays a\r
+terrible price for doing so?" suggested the painter.\r
+\r
+"Yes, we are overcharged for everything nowadays. I should fancy that\r
+the real tragedy of the poor is that they can afford nothing but\r
+self-denial. Beautiful sins, like beautiful things, are the privilege\r
+of the rich."\r
+\r
+"One has to pay in other ways but money."\r
+\r
+"What sort of ways, Basil?"\r
+\r
+"Oh! I should fancy in remorse, in suffering, in ... well, in the\r
+consciousness of degradation."\r
+\r
+Lord Henry shrugged his shoulders. "My dear fellow, mediaeval art is\r
+charming, but mediaeval emotions are out of date. One can use them in\r
+fiction, of course. But then the only things that one can use in\r
+fiction are the things that one has ceased to use in fact. Believe me,\r
+no civilized man ever regrets a pleasure, and no uncivilized man ever\r
+knows what a pleasure is."\r
+\r
+"I know what pleasure is," cried Dorian Gray. "It is to adore some\r
+one."\r
+\r
+"That is certainly better than being adored," he answered, toying with\r
+some fruits. "Being adored is a nuisance. Women treat us just as\r
+humanity treats its gods. They worship us, and are always bothering us\r
+to do something for them."\r
+\r
+"I should have said that whatever they ask for they had first given to\r
+us," murmured the lad gravely. "They create love in our natures. They\r
+have a right to demand it back."\r
+\r
+"That is quite true, Dorian," cried Hallward.\r
+\r
+"Nothing is ever quite true," said Lord Henry.\r
+\r
+"This is," interrupted Dorian. "You must admit, Harry, that women give\r
+to men the very gold of their lives."\r
+\r
+"Possibly," he sighed, "but they invariably want it back in such very\r
+small change. That is the worry. Women, as some witty Frenchman once\r
+put it, inspire us with the desire to do masterpieces and always\r
+prevent us from carrying them out."\r
+\r
+"Harry, you are dreadful! I don't know why I like you so much."\r
+\r
+"You will always like me, Dorian," he replied. "Will you have some\r
+coffee, you fellows? Waiter, bring coffee, and _fine-champagne_, and\r
+some cigarettes. No, don't mind the cigarettes--I have some. Basil, I\r
+can't allow you to smoke cigars. You must have a cigarette. A\r
+cigarette is the perfect type of a perfect pleasure. It is exquisite,\r
+and it leaves one unsatisfied. What more can one want? Yes, Dorian,\r
+you will always be fond of me. I represent to you all the sins you\r
+have never had the courage to commit."\r
+\r
+"What nonsense you talk, Harry!" cried the lad, taking a light from a\r
+fire-breathing silver dragon that the waiter had placed on the table.\r
+"Let us go down to the theatre. When Sibyl comes on the stage you will\r
+have a new ideal of life. She will represent something to you that you\r
+have never known."\r
+\r
+"I have known everything," said Lord Henry, with a tired look in his\r
+eyes, "but I am always ready for a new emotion. I am afraid, however,\r
+that, for me at any rate, there is no such thing. Still, your\r
+wonderful girl may thrill me. I love acting. It is so much more real\r
+than life. Let us go. Dorian, you will come with me. I am so sorry,\r
+Basil, but there is only room for two in the brougham. You must follow\r
+us in a hansom."\r
+\r
+They got up and put on their coats, sipping their coffee standing. The\r
+painter was silent and preoccupied. There was a gloom over him. He\r
+could not bear this marriage, and yet it seemed to him to be better\r
+than many other things that might have happened. After a few minutes,\r
+they all passed downstairs. He drove off by himself, as had been\r
+arranged, and watched the flashing lights of the little brougham in\r
+front of him. A strange sense of loss came over him. He felt that\r
+Dorian Gray would never again be to him all that he had been in the\r
+past. Life had come between them.... His eyes darkened, and the\r
+crowded flaring streets became blurred to his eyes. When the cab drew\r
+up at the theatre, it seemed to him that he had grown years older.\r
+\r
+\r
+\r
+CHAPTER 7\r
+\r
+For some reason or other, the house was crowded that night, and the fat\r
+Jew manager who met them at the door was beaming from ear to ear with\r
+an oily tremulous smile. He escorted them to their box with a sort of\r
+pompous humility, waving his fat jewelled hands and talking at the top\r
+of his voice. Dorian Gray loathed him more than ever. He felt as if\r
+he had come to look for Miranda and had been met by Caliban. Lord\r
+Henry, upon the other hand, rather liked him. At least he declared he\r
+did, and insisted on shaking him by the hand and assuring him that he\r
+was proud to meet a man who had discovered a real genius and gone\r
+bankrupt over a poet. Hallward amused himself with watching the faces\r
+in the pit. The heat was terribly oppressive, and the huge sunlight\r
+flamed like a monstrous dahlia with petals of yellow fire. The youths\r
+in the gallery had taken off their coats and waistcoats and hung them\r
+over the side. They talked to each other across the theatre and shared\r
+their oranges with the tawdry girls who sat beside them. Some women\r
+were laughing in the pit. Their voices were horribly shrill and\r
+discordant. The sound of the popping of corks came from the bar.\r
+\r
+"What a place to find one's divinity in!" said Lord Henry.\r
+\r
+"Yes!" answered Dorian Gray. "It was here I found her, and she is\r
+divine beyond all living things. When she acts, you will forget\r
+everything. These common rough people, with their coarse faces and\r
+brutal gestures, become quite different when she is on the stage. They\r
+sit silently and watch her. They weep and laugh as she wills them to\r
+do. She makes them as responsive as a violin. She spiritualizes them,\r
+and one feels that they are of the same flesh and blood as one's self."\r
+\r
+"The same flesh and blood as one's self! Oh, I hope not!" exclaimed\r
+Lord Henry, who was scanning the occupants of the gallery through his\r
+opera-glass.\r
+\r
+"Don't pay any attention to him, Dorian," said the painter. "I\r
+understand what you mean, and I believe in this girl. Any one you love\r
+must be marvellous, and any girl who has the effect you describe must\r
+be fine and noble. To spiritualize one's age--that is something worth\r
+doing. If this girl can give a soul to those who have lived without\r
+one, if she can create the sense of beauty in people whose lives have\r
+been sordid and ugly, if she can strip them of their selfishness and\r
+lend them tears for sorrows that are not their own, she is worthy of\r
+all your adoration, worthy of the adoration of the world. This\r
+marriage is quite right. I did not think so at first, but I admit it\r
+now. The gods made Sibyl Vane for you. Without her you would have\r
+been incomplete."\r
+\r
+"Thanks, Basil," answered Dorian Gray, pressing his hand. "I knew that\r
+you would understand me. Harry is so cynical, he terrifies me. But\r
+here is the orchestra. It is quite dreadful, but it only lasts for\r
+about five minutes. Then the curtain rises, and you will see the girl\r
+to whom I am going to give all my life, to whom I have given everything\r
+that is good in me."\r
+\r
+A quarter of an hour afterwards, amidst an extraordinary turmoil of\r
+applause, Sibyl Vane stepped on to the stage. Yes, she was certainly\r
+lovely to look at--one of the loveliest creatures, Lord Henry thought,\r
+that he had ever seen. There was something of the fawn in her shy\r
+grace and startled eyes. A faint blush, like the shadow of a rose in a\r
+mirror of silver, came to her cheeks as she glanced at the crowded\r
+enthusiastic house. She stepped back a few paces and her lips seemed\r
+to tremble. Basil Hallward leaped to his feet and began to applaud.\r
+Motionless, and as one in a dream, sat Dorian Gray, gazing at her.\r
+Lord Henry peered through his glasses, murmuring, "Charming! charming!"\r
+\r
+The scene was the hall of Capulet's house, and Romeo in his pilgrim's\r
+dress had entered with Mercutio and his other friends. The band, such\r
+as it was, struck up a few bars of music, and the dance began. Through\r
+the crowd of ungainly, shabbily dressed actors, Sibyl Vane moved like a\r
+creature from a finer world. Her body swayed, while she danced, as a\r
+plant sways in the water. The curves of her throat were the curves of\r
+a white lily. Her hands seemed to be made of cool ivory.\r
+\r
+Yet she was curiously listless. She showed no sign of joy when her\r
+eyes rested on Romeo. The few words she had to speak--\r
+\r
+ Good pilgrim, you do wrong your hand too much,\r
+ Which mannerly devotion shows in this;\r
+ For saints have hands that pilgrims' hands do touch,\r
+ And palm to palm is holy palmers' kiss--\r
+\r
+with the brief dialogue that follows, were spoken in a thoroughly\r
+artificial manner. The voice was exquisite, but from the point of view\r
+of tone it was absolutely false. It was wrong in colour. It took away\r
+all the life from the verse. It made the passion unreal.\r
+\r
+Dorian Gray grew pale as he watched her. He was puzzled and anxious.\r
+Neither of his friends dared to say anything to him. She seemed to\r
+them to be absolutely incompetent. They were horribly disappointed.\r
+\r
+Yet they felt that the true test of any Juliet is the balcony scene of\r
+the second act. They waited for that. If she failed there, there was\r
+nothing in her.\r
+\r
+She looked charming as she came out in the moonlight. That could not\r
+be denied. But the staginess of her acting was unbearable, and grew\r
+worse as she went on. Her gestures became absurdly artificial. She\r
+overemphasized everything that she had to say. The beautiful passage--\r
+\r
+ Thou knowest the mask of night is on my face,\r
+ Else would a maiden blush bepaint my cheek\r
+ For that which thou hast heard me speak to-night--\r
+\r
+was declaimed with the painful precision of a schoolgirl who has been\r
+taught to recite by some second-rate professor of elocution. When she\r
+leaned over the balcony and came to those wonderful lines--\r
+\r
+ Although I joy in thee,\r
+ I have no joy of this contract to-night:\r
+ It is too rash, too unadvised, too sudden;\r
+ Too like the lightning, which doth cease to be\r
+ Ere one can say, "It lightens." Sweet, good-night!\r
+ This bud of love by summer's ripening breath\r
+ May prove a beauteous flower when next we meet--\r
+\r
+she spoke the words as though they conveyed no meaning to her. It was\r
+not nervousness. Indeed, so far from being nervous, she was absolutely\r
+self-contained. It was simply bad art. She was a complete failure.\r
+\r
+Even the common uneducated audience of the pit and gallery lost their\r
+interest in the play. They got restless, and began to talk loudly and\r
+to whistle. The Jew manager, who was standing at the back of the\r
+dress-circle, stamped and swore with rage. The only person unmoved was\r
+the girl herself.\r
+\r
+When the second act was over, there came a storm of hisses, and Lord\r
+Henry got up from his chair and put on his coat. "She is quite\r
+beautiful, Dorian," he said, "but she can't act. Let us go."\r
+\r
+"I am going to see the play through," answered the lad, in a hard\r
+bitter voice. "I am awfully sorry that I have made you waste an\r
+evening, Harry. I apologize to you both."\r
+\r
+"My dear Dorian, I should think Miss Vane was ill," interrupted\r
+Hallward. "We will come some other night."\r
+\r
+"I wish she were ill," he rejoined. "But she seems to me to be simply\r
+callous and cold. She has entirely altered. Last night she was a\r
+great artist. This evening she is merely a commonplace mediocre\r
+actress."\r
+\r
+"Don't talk like that about any one you love, Dorian. Love is a more\r
+wonderful thing than art."\r
+\r
+"They are both simply forms of imitation," remarked Lord Henry. "But\r
+do let us go. Dorian, you must not stay here any longer. It is not\r
+good for one's morals to see bad acting. Besides, I don't suppose you\r
+will want your wife to act, so what does it matter if she plays Juliet\r
+like a wooden doll? She is very lovely, and if she knows as little\r
+about life as she does about acting, she will be a delightful\r
+experience. There are only two kinds of people who are really\r
+fascinating--people who know absolutely everything, and people who know\r
+absolutely nothing. Good heavens, my dear boy, don't look so tragic!\r
+The secret of remaining young is never to have an emotion that is\r
+unbecoming. Come to the club with Basil and myself. We will smoke\r
+cigarettes and drink to the beauty of Sibyl Vane. She is beautiful.\r
+What more can you want?"\r
+\r
+"Go away, Harry," cried the lad. "I want to be alone. Basil, you must\r
+go. Ah! can't you see that my heart is breaking?" The hot tears came\r
+to his eyes. His lips trembled, and rushing to the back of the box, he\r
+leaned up against the wall, hiding his face in his hands.\r
+\r
+"Let us go, Basil," said Lord Henry with a strange tenderness in his\r
+voice, and the two young men passed out together.\r
+\r
+A few moments afterwards the footlights flared up and the curtain rose\r
+on the third act. Dorian Gray went back to his seat. He looked pale,\r
+and proud, and indifferent. The play dragged on, and seemed\r
+interminable. Half of the audience went out, tramping in heavy boots\r
+and laughing. The whole thing was a _fiasco_. The last act was played\r
+to almost empty benches. The curtain went down on a titter and some\r
+groans.\r
+\r
+As soon as it was over, Dorian Gray rushed behind the scenes into the\r
+greenroom. The girl was standing there alone, with a look of triumph\r
+on her face. Her eyes were lit with an exquisite fire. There was a\r
+radiance about her. Her parted lips were smiling over some secret of\r
+their own.\r
+\r
+When he entered, she looked at him, and an expression of infinite joy\r
+came over her. "How badly I acted to-night, Dorian!" she cried.\r
+\r
+"Horribly!" he answered, gazing at her in amazement. "Horribly! It\r
+was dreadful. Are you ill? You have no idea what it was. You have no\r
+idea what I suffered."\r
+\r
+The girl smiled. "Dorian," she answered, lingering over his name with\r
+long-drawn music in her voice, as though it were sweeter than honey to\r
+the red petals of her mouth. "Dorian, you should have understood. But\r
+you understand now, don't you?"\r
+\r
+"Understand what?" he asked, angrily.\r
+\r
+"Why I was so bad to-night. Why I shall always be bad. Why I shall\r
+never act well again."\r
+\r
+He shrugged his shoulders. "You are ill, I suppose. When you are ill\r
+you shouldn't act. You make yourself ridiculous. My friends were\r
+bored. I was bored."\r
+\r
+She seemed not to listen to him. She was transfigured with joy. An\r
+ecstasy of happiness dominated her.\r
+\r
+"Dorian, Dorian," she cried, "before I knew you, acting was the one\r
+reality of my life. It was only in the theatre that I lived. I\r
+thought that it was all true. I was Rosalind one night and Portia the\r
+other. The joy of Beatrice was my joy, and the sorrows of Cordelia\r
+were mine also. I believed in everything. The common people who acted\r
+with me seemed to me to be godlike. The painted scenes were my world.\r
+I knew nothing but shadows, and I thought them real. You came--oh, my\r
+beautiful love!--and you freed my soul from prison. You taught me what\r
+reality really is. To-night, for the first time in my life, I saw\r
+through the hollowness, the sham, the silliness of the empty pageant in\r
+which I had always played. To-night, for the first time, I became\r
+conscious that the Romeo was hideous, and old, and painted, that the\r
+moonlight in the orchard was false, that the scenery was vulgar, and\r
+that the words I had to speak were unreal, were not my words, were not\r
+what I wanted to say. You had brought me something higher, something\r
+of which all art is but a reflection. You had made me understand what\r
+love really is. My love! My love! Prince Charming! Prince of life!\r
+I have grown sick of shadows. You are more to me than all art can ever\r
+be. What have I to do with the puppets of a play? When I came on\r
+to-night, I could not understand how it was that everything had gone\r
+from me. I thought that I was going to be wonderful. I found that I\r
+could do nothing. Suddenly it dawned on my soul what it all meant.\r
+The knowledge was exquisite to me. I heard them hissing, and I smiled.\r
+What could they know of love such as ours? Take me away, Dorian--take\r
+me away with you, where we can be quite alone. I hate the stage. I\r
+might mimic a passion that I do not feel, but I cannot mimic one that\r
+burns me like fire. Oh, Dorian, Dorian, you understand now what it\r
+signifies? Even if I could do it, it would be profanation for me to\r
+play at being in love. You have made me see that."\r
+\r
+He flung himself down on the sofa and turned away his face. "You have\r
+killed my love," he muttered.\r
+\r
+She looked at him in wonder and laughed. He made no answer. She came\r
+across to him, and with her little fingers stroked his hair. She knelt\r
+down and pressed his hands to her lips. He drew them away, and a\r
+shudder ran through him.\r
+\r
+Then he leaped up and went to the door. "Yes," he cried, "you have\r
+killed my love. You used to stir my imagination. Now you don't even\r
+stir my curiosity. You simply produce no effect. I loved you because\r
+you were marvellous, because you had genius and intellect, because you\r
+realized the dreams of great poets and gave shape and substance to the\r
+shadows of art. You have thrown it all away. You are shallow and\r
+stupid. My God! how mad I was to love you! What a fool I have been!\r
+You are nothing to me now. I will never see you again. I will never\r
+think of you. I will never mention your name. You don't know what you\r
+were to me, once. Why, once ... Oh, I can't bear to think of it! I\r
+wish I had never laid eyes upon you! You have spoiled the romance of\r
+my life. How little you can know of love, if you say it mars your art!\r
+Without your art, you are nothing. I would have made you famous,\r
+splendid, magnificent. The world would have worshipped you, and you\r
+would have borne my name. What are you now? A third-rate actress with\r
+a pretty face."\r
+\r
+The girl grew white, and trembled. She clenched her hands together,\r
+and her voice seemed to catch in her throat. "You are not serious,\r
+Dorian?" she murmured. "You are acting."\r
+\r
+"Acting! I leave that to you. You do it so well," he answered\r
+bitterly.\r
+\r
+She rose from her knees and, with a piteous expression of pain in her\r
+face, came across the room to him. She put her hand upon his arm and\r
+looked into his eyes. He thrust her back. "Don't touch me!" he cried.\r
+\r
+A low moan broke from her, and she flung herself at his feet and lay\r
+there like a trampled flower. "Dorian, Dorian, don't leave me!" she\r
+whispered. "I am so sorry I didn't act well. I was thinking of you\r
+all the time. But I will try--indeed, I will try. It came so suddenly\r
+across me, my love for you. I think I should never have known it if\r
+you had not kissed me--if we had not kissed each other. Kiss me again,\r
+my love. Don't go away from me. I couldn't bear it. Oh! don't go\r
+away from me. My brother ... No; never mind. He didn't mean it. He\r
+was in jest.... But you, oh! can't you forgive me for to-night? I will\r
+work so hard and try to improve. Don't be cruel to me, because I love\r
+you better than anything in the world. After all, it is only once that\r
+I have not pleased you. But you are quite right, Dorian. I should\r
+have shown myself more of an artist. It was foolish of me, and yet I\r
+couldn't help it. Oh, don't leave me, don't leave me." A fit of\r
+passionate sobbing choked her. She crouched on the floor like a\r
+wounded thing, and Dorian Gray, with his beautiful eyes, looked down at\r
+her, and his chiselled lips curled in exquisite disdain. There is\r
+always something ridiculous about the emotions of people whom one has\r
+ceased to love. Sibyl Vane seemed to him to be absurdly melodramatic.\r
+Her tears and sobs annoyed him.\r
+\r
+"I am going," he said at last in his calm clear voice. "I don't wish\r
+to be unkind, but I can't see you again. You have disappointed me."\r
+\r
+She wept silently, and made no answer, but crept nearer. Her little\r
+hands stretched blindly out, and appeared to be seeking for him. He\r
+turned on his heel and left the room. In a few moments he was out of\r
+the theatre.\r
+\r
+Where he went to he hardly knew. He remembered wandering through dimly\r
+lit streets, past gaunt, black-shadowed archways and evil-looking\r
+houses. Women with hoarse voices and harsh laughter had called after\r
+him. Drunkards had reeled by, cursing and chattering to themselves\r
+like monstrous apes. He had seen grotesque children huddled upon\r
+door-steps, and heard shrieks and oaths from gloomy courts.\r
+\r
+As the dawn was just breaking, he found himself close to Covent Garden.\r
+The darkness lifted, and, flushed with faint fires, the sky hollowed\r
+itself into a perfect pearl. Huge carts filled with nodding lilies\r
+rumbled slowly down the polished empty street. The air was heavy with\r
+the perfume of the flowers, and their beauty seemed to bring him an\r
+anodyne for his pain. He followed into the market and watched the men\r
+unloading their waggons. A white-smocked carter offered him some\r
+cherries. He thanked him, wondered why he refused to accept any money\r
+for them, and began to eat them listlessly. They had been plucked at\r
+midnight, and the coldness of the moon had entered into them. A long\r
+line of boys carrying crates of striped tulips, and of yellow and red\r
+roses, defiled in front of him, threading their way through the huge,\r
+jade-green piles of vegetables. Under the portico, with its grey,\r
+sun-bleached pillars, loitered a troop of draggled bareheaded girls,\r
+waiting for the auction to be over. Others crowded round the swinging\r
+doors of the coffee-house in the piazza. The heavy cart-horses slipped\r
+and stamped upon the rough stones, shaking their bells and trappings.\r
+Some of the drivers were lying asleep on a pile of sacks. Iris-necked\r
+and pink-footed, the pigeons ran about picking up seeds.\r
+\r
+After a little while, he hailed a hansom and drove home. For a few\r
+moments he loitered upon the doorstep, looking round at the silent\r
+square, with its blank, close-shuttered windows and its staring blinds.\r
+The sky was pure opal now, and the roofs of the houses glistened like\r
+silver against it. From some chimney opposite a thin wreath of smoke\r
+was rising. It curled, a violet riband, through the nacre-coloured air.\r
+\r
+In the huge gilt Venetian lantern, spoil of some Doge's barge, that\r
+hung from the ceiling of the great, oak-panelled hall of entrance,\r
+lights were still burning from three flickering jets: thin blue petals\r
+of flame they seemed, rimmed with white fire. He turned them out and,\r
+having thrown his hat and cape on the table, passed through the library\r
+towards the door of his bedroom, a large octagonal chamber on the\r
+ground floor that, in his new-born feeling for luxury, he had just had\r
+decorated for himself and hung with some curious Renaissance tapestries\r
+that had been discovered stored in a disused attic at Selby Royal. As\r
+he was turning the handle of the door, his eye fell upon the portrait\r
+Basil Hallward had painted of him. He started back as if in surprise.\r
+Then he went on into his own room, looking somewhat puzzled. After he\r
+had taken the button-hole out of his coat, he seemed to hesitate.\r
+Finally, he came back, went over to the picture, and examined it. In\r
+the dim arrested light that struggled through the cream-coloured silk\r
+blinds, the face appeared to him to be a little changed. The\r
+expression looked different. One would have said that there was a\r
+touch of cruelty in the mouth. It was certainly strange.\r
+\r
+He turned round and, walking to the window, drew up the blind. The\r
+bright dawn flooded the room and swept the fantastic shadows into dusky\r
+corners, where they lay shuddering. But the strange expression that he\r
+had noticed in the face of the portrait seemed to linger there, to be\r
+more intensified even. The quivering ardent sunlight showed him the\r
+lines of cruelty round the mouth as clearly as if he had been looking\r
+into a mirror after he had done some dreadful thing.\r
+\r
+He winced and, taking up from the table an oval glass framed in ivory\r
+Cupids, one of Lord Henry's many presents to him, glanced hurriedly\r
+into its polished depths. No line like that warped his red lips. What\r
+did it mean?\r
+\r
+He rubbed his eyes, and came close to the picture, and examined it\r
+again. There were no signs of any change when he looked into the\r
+actual painting, and yet there was no doubt that the whole expression\r
+had altered. It was not a mere fancy of his own. The thing was\r
+horribly apparent.\r
+\r
+He threw himself into a chair and began to think. Suddenly there\r
+flashed across his mind what he had said in Basil Hallward's studio the\r
+day the picture had been finished. Yes, he remembered it perfectly.\r
+He had uttered a mad wish that he himself might remain young, and the\r
+portrait grow old; that his own beauty might be untarnished, and the\r
+face on the canvas bear the burden of his passions and his sins; that\r
+the painted image might be seared with the lines of suffering and\r
+thought, and that he might keep all the delicate bloom and loveliness\r
+of his then just conscious boyhood. Surely his wish had not been\r
+fulfilled? Such things were impossible. It seemed monstrous even to\r
+think of them. And, yet, there was the picture before him, with the\r
+touch of cruelty in the mouth.\r
+\r
+Cruelty! Had he been cruel? It was the girl's fault, not his. He had\r
+dreamed of her as a great artist, had given his love to her because he\r
+had thought her great. Then she had disappointed him. She had been\r
+shallow and unworthy. And, yet, a feeling of infinite regret came over\r
+him, as he thought of her lying at his feet sobbing like a little\r
+child. He remembered with what callousness he had watched her. Why\r
+had he been made like that? Why had such a soul been given to him?\r
+But he had suffered also. During the three terrible hours that the\r
+play had lasted, he had lived centuries of pain, aeon upon aeon of\r
+torture. His life was well worth hers. She had marred him for a\r
+moment, if he had wounded her for an age. Besides, women were better\r
+suited to bear sorrow than men. They lived on their emotions. They\r
+only thought of their emotions. When they took lovers, it was merely\r
+to have some one with whom they could have scenes. Lord Henry had told\r
+him that, and Lord Henry knew what women were. Why should he trouble\r
+about Sibyl Vane? She was nothing to him now.\r
+\r
+But the picture? What was he to say of that? It held the secret of\r
+his life, and told his story. It had taught him to love his own\r
+beauty. Would it teach him to loathe his own soul? Would he ever look\r
+at it again?\r
+\r
+No; it was merely an illusion wrought on the troubled senses. The\r
+horrible night that he had passed had left phantoms behind it.\r
+Suddenly there had fallen upon his brain that tiny scarlet speck that\r
+makes men mad. The picture had not changed. It was folly to think so.\r
+\r
+Yet it was watching him, with its beautiful marred face and its cruel\r
+smile. Its bright hair gleamed in the early sunlight. Its blue eyes\r
+met his own. A sense of infinite pity, not for himself, but for the\r
+painted image of himself, came over him. It had altered already, and\r
+would alter more. Its gold would wither into grey. Its red and white\r
+roses would die. For every sin that he committed, a stain would fleck\r
+and wreck its fairness. But he would not sin. The picture, changed or\r
+unchanged, would be to him the visible emblem of conscience. He would\r
+resist temptation. He would not see Lord Henry any more--would not, at\r
+any rate, listen to those subtle poisonous theories that in Basil\r
+Hallward's garden had first stirred within him the passion for\r
+impossible things. He would go back to Sibyl Vane, make her amends,\r
+marry her, try to love her again. Yes, it was his duty to do so. She\r
+must have suffered more than he had. Poor child! He had been selfish\r
+and cruel to her. The fascination that she had exercised over him\r
+would return. They would be happy together. His life with her would\r
+be beautiful and pure.\r
+\r
+He got up from his chair and drew a large screen right in front of the\r
+portrait, shuddering as he glanced at it. "How horrible!" he murmured\r
+to himself, and he walked across to the window and opened it. When he\r
+stepped out on to the grass, he drew a deep breath. The fresh morning\r
+air seemed to drive away all his sombre passions. He thought only of\r
+Sibyl. A faint echo of his love came back to him. He repeated her\r
+name over and over again. The birds that were singing in the\r
+dew-drenched garden seemed to be telling the flowers about her.\r
+\r
+\r
+\r
+CHAPTER 8\r
+\r
+It was long past noon when he awoke. His valet had crept several times\r
+on tiptoe into the room to see if he was stirring, and had wondered\r
+what made his young master sleep so late. Finally his bell sounded,\r
+and Victor came in softly with a cup of tea, and a pile of letters, on\r
+a small tray of old Sevres china, and drew back the olive-satin\r
+curtains, with their shimmering blue lining, that hung in front of the\r
+three tall windows.\r
+\r
+"Monsieur has well slept this morning," he said, smiling.\r
+\r
+"What o'clock is it, Victor?" asked Dorian Gray drowsily.\r
+\r
+"One hour and a quarter, Monsieur."\r
+\r
+How late it was! He sat up, and having sipped some tea, turned over\r
+his letters. One of them was from Lord Henry, and had been brought by\r
+hand that morning. He hesitated for a moment, and then put it aside.\r
+The others he opened listlessly. They contained the usual collection\r
+of cards, invitations to dinner, tickets for private views, programmes\r
+of charity concerts, and the like that are showered on fashionable\r
+young men every morning during the season. There was a rather heavy\r
+bill for a chased silver Louis-Quinze toilet-set that he had not yet\r
+had the courage to send on to his guardians, who were extremely\r
+old-fashioned people and did not realize that we live in an age when\r
+unnecessary things are our only necessities; and there were several\r
+very courteously worded communications from Jermyn Street money-lenders\r
+offering to advance any sum of money at a moment's notice and at the\r
+most reasonable rates of interest.\r
+\r
+After about ten minutes he got up, and throwing on an elaborate\r
+dressing-gown of silk-embroidered cashmere wool, passed into the\r
+onyx-paved bathroom. The cool water refreshed him after his long\r
+sleep. He seemed to have forgotten all that he had gone through. A\r
+dim sense of having taken part in some strange tragedy came to him once\r
+or twice, but there was the unreality of a dream about it.\r
+\r
+As soon as he was dressed, he went into the library and sat down to a\r
+light French breakfast that had been laid out for him on a small round\r
+table close to the open window. It was an exquisite day. The warm air\r
+seemed laden with spices. A bee flew in and buzzed round the\r
+blue-dragon bowl that, filled with sulphur-yellow roses, stood before\r
+him. He felt perfectly happy.\r
+\r
+Suddenly his eye fell on the screen that he had placed in front of the\r
+portrait, and he started.\r
+\r
+"Too cold for Monsieur?" asked his valet, putting an omelette on the\r
+table. "I shut the window?"\r
+\r
+Dorian shook his head. "I am not cold," he murmured.\r
+\r
+Was it all true? Had the portrait really changed? Or had it been\r
+simply his own imagination that had made him see a look of evil where\r
+there had been a look of joy? Surely a painted canvas could not alter?\r
+The thing was absurd. It would serve as a tale to tell Basil some day.\r
+It would make him smile.\r
+\r
+And, yet, how vivid was his recollection of the whole thing! First in\r
+the dim twilight, and then in the bright dawn, he had seen the touch of\r
+cruelty round the warped lips. He almost dreaded his valet leaving the\r
+room. He knew that when he was alone he would have to examine the\r
+portrait. He was afraid of certainty. When the coffee and cigarettes\r
+had been brought and the man turned to go, he felt a wild desire to\r
+tell him to remain. As the door was closing behind him, he called him\r
+back. The man stood waiting for his orders. Dorian looked at him for\r
+a moment. "I am not at home to any one, Victor," he said with a sigh.\r
+The man bowed and retired.\r
+\r
+Then he rose from the table, lit a cigarette, and flung himself down on\r
+a luxuriously cushioned couch that stood facing the screen. The screen\r
+was an old one, of gilt Spanish leather, stamped and wrought with a\r
+rather florid Louis-Quatorze pattern. He scanned it curiously,\r
+wondering if ever before it had concealed the secret of a man's life.\r
+\r
+Should he move it aside, after all? Why not let it stay there? What\r
+was the use of knowing? If the thing was true, it was terrible. If it\r
+was not true, why trouble about it? But what if, by some fate or\r
+deadlier chance, eyes other than his spied behind and saw the horrible\r
+change? What should he do if Basil Hallward came and asked to look at\r
+his own picture? Basil would be sure to do that. No; the thing had to\r
+be examined, and at once. Anything would be better than this dreadful\r
+state of doubt.\r
+\r
+He got up and locked both doors. At least he would be alone when he\r
+looked upon the mask of his shame. Then he drew the screen aside and\r
+saw himself face to face. It was perfectly true. The portrait had\r
+altered.\r
+\r
+As he often remembered afterwards, and always with no small wonder, he\r
+found himself at first gazing at the portrait with a feeling of almost\r
+scientific interest. That such a change should have taken place was\r
+incredible to him. And yet it was a fact. Was there some subtle\r
+affinity between the chemical atoms that shaped themselves into form\r
+and colour on the canvas and the soul that was within him? Could it be\r
+that what that soul thought, they realized?--that what it dreamed, they\r
+made true? Or was there some other, more terrible reason? He\r
+shuddered, and felt afraid, and, going back to the couch, lay there,\r
+gazing at the picture in sickened horror.\r
+\r
+One thing, however, he felt that it had done for him. It had made him\r
+conscious how unjust, how cruel, he had been to Sibyl Vane. It was not\r
+too late to make reparation for that. She could still be his wife.\r
+His unreal and selfish love would yield to some higher influence, would\r
+be transformed into some nobler passion, and the portrait that Basil\r
+Hallward had painted of him would be a guide to him through life, would\r
+be to him what holiness is to some, and conscience to others, and the\r
+fear of God to us all. There were opiates for remorse, drugs that\r
+could lull the moral sense to sleep. But here was a visible symbol of\r
+the degradation of sin. Here was an ever-present sign of the ruin men\r
+brought upon their souls.\r
+\r
+Three o'clock struck, and four, and the half-hour rang its double\r
+chime, but Dorian Gray did not stir. He was trying to gather up the\r
+scarlet threads of life and to weave them into a pattern; to find his\r
+way through the sanguine labyrinth of passion through which he was\r
+wandering. He did not know what to do, or what to think. Finally, he\r
+went over to the table and wrote a passionate letter to the girl he had\r
+loved, imploring her forgiveness and accusing himself of madness. He\r
+covered page after page with wild words of sorrow and wilder words of\r
+pain. There is a luxury in self-reproach. When we blame ourselves, we\r
+feel that no one else has a right to blame us. It is the confession,\r
+not the priest, that gives us absolution. When Dorian had finished the\r
+letter, he felt that he had been forgiven.\r
+\r
+Suddenly there came a knock to the door, and he heard Lord Henry's\r
+voice outside. "My dear boy, I must see you. Let me in at once. I\r
+can't bear your shutting yourself up like this."\r
+\r
+He made no answer at first, but remained quite still. The knocking\r
+still continued and grew louder. Yes, it was better to let Lord Henry\r
+in, and to explain to him the new life he was going to lead, to quarrel\r
+with him if it became necessary to quarrel, to part if parting was\r
+inevitable. He jumped up, drew the screen hastily across the picture,\r
+and unlocked the door.\r
+\r
+"I am so sorry for it all, Dorian," said Lord Henry as he entered.\r
+"But you must not think too much about it."\r
+\r
+"Do you mean about Sibyl Vane?" asked the lad.\r
+\r
+"Yes, of course," answered Lord Henry, sinking into a chair and slowly\r
+pulling off his yellow gloves. "It is dreadful, from one point of\r
+view, but it was not your fault. Tell me, did you go behind and see\r
+her, after the play was over?"\r
+\r
+"Yes."\r
+\r
+"I felt sure you had. Did you make a scene with her?"\r
+\r
+"I was brutal, Harry--perfectly brutal. But it is all right now. I am\r
+not sorry for anything that has happened. It has taught me to know\r
+myself better."\r
+\r
+"Ah, Dorian, I am so glad you take it in that way! I was afraid I\r
+would find you plunged in remorse and tearing that nice curly hair of\r
+yours."\r
+\r
+"I have got through all that," said Dorian, shaking his head and\r
+smiling. "I am perfectly happy now. I know what conscience is, to\r
+begin with. It is not what you told me it was. It is the divinest\r
+thing in us. Don't sneer at it, Harry, any more--at least not before\r
+me. I want to be good. I can't bear the idea of my soul being\r
+hideous."\r
+\r
+"A very charming artistic basis for ethics, Dorian! I congratulate you\r
+on it. But how are you going to begin?"\r
+\r
+"By marrying Sibyl Vane."\r
+\r
+"Marrying Sibyl Vane!" cried Lord Henry, standing up and looking at him\r
+in perplexed amazement. "But, my dear Dorian--"\r
+\r
+"Yes, Harry, I know what you are going to say. Something dreadful\r
+about marriage. Don't say it. Don't ever say things of that kind to\r
+me again. Two days ago I asked Sibyl to marry me. I am not going to\r
+break my word to her. She is to be my wife."\r
+\r
+"Your wife! Dorian! ... Didn't you get my letter? I wrote to you this\r
+morning, and sent the note down by my own man."\r
+\r
+"Your letter? Oh, yes, I remember. I have not read it yet, Harry. I\r
+was afraid there might be something in it that I wouldn't like. You\r
+cut life to pieces with your epigrams."\r
+\r
+"You know nothing then?"\r
+\r
+"What do you mean?"\r
+\r
+Lord Henry walked across the room, and sitting down by Dorian Gray,\r
+took both his hands in his own and held them tightly. "Dorian," he\r
+said, "my letter--don't be frightened--was to tell you that Sibyl Vane\r
+is dead."\r
+\r
+A cry of pain broke from the lad's lips, and he leaped to his feet,\r
+tearing his hands away from Lord Henry's grasp. "Dead! Sibyl dead!\r
+It is not true! It is a horrible lie! How dare you say it?"\r
+\r
+"It is quite true, Dorian," said Lord Henry, gravely. "It is in all\r
+the morning papers. I wrote down to you to ask you not to see any one\r
+till I came. There will have to be an inquest, of course, and you must\r
+not be mixed up in it. Things like that make a man fashionable in\r
+Paris. But in London people are so prejudiced. Here, one should never\r
+make one's _debut_ with a scandal. One should reserve that to give an\r
+interest to one's old age. I suppose they don't know your name at the\r
+theatre? If they don't, it is all right. Did any one see you going\r
+round to her room? That is an important point."\r
+\r
+Dorian did not answer for a few moments. He was dazed with horror.\r
+Finally he stammered, in a stifled voice, "Harry, did you say an\r
+inquest? What did you mean by that? Did Sibyl--? Oh, Harry, I can't\r
+bear it! But be quick. Tell me everything at once."\r
+\r
+"I have no doubt it was not an accident, Dorian, though it must be put\r
+in that way to the public. It seems that as she was leaving the\r
+theatre with her mother, about half-past twelve or so, she said she had\r
+forgotten something upstairs. They waited some time for her, but she\r
+did not come down again. They ultimately found her lying dead on the\r
+floor of her dressing-room. She had swallowed something by mistake,\r
+some dreadful thing they use at theatres. I don't know what it was,\r
+but it had either prussic acid or white lead in it. I should fancy it\r
+was prussic acid, as she seems to have died instantaneously."\r
+\r
+"Harry, Harry, it is terrible!" cried the lad.\r
+\r
+"Yes; it is very tragic, of course, but you must not get yourself mixed\r
+up in it. I see by _The Standard_ that she was seventeen. I should have\r
+thought she was almost younger than that. She looked such a child, and\r
+seemed to know so little about acting. Dorian, you mustn't let this\r
+thing get on your nerves. You must come and dine with me, and\r
+afterwards we will look in at the opera. It is a Patti night, and\r
+everybody will be there. You can come to my sister's box. She has got\r
+some smart women with her."\r
+\r
+"So I have murdered Sibyl Vane," said Dorian Gray, half to himself,\r
+"murdered her as surely as if I had cut her little throat with a knife.\r
+Yet the roses are not less lovely for all that. The birds sing just as\r
+happily in my garden. And to-night I am to dine with you, and then go\r
+on to the opera, and sup somewhere, I suppose, afterwards. How\r
+extraordinarily dramatic life is! If I had read all this in a book,\r
+Harry, I think I would have wept over it. Somehow, now that it has\r
+happened actually, and to me, it seems far too wonderful for tears.\r
+Here is the first passionate love-letter I have ever written in my\r
+life. Strange, that my first passionate love-letter should have been\r
+addressed to a dead girl. Can they feel, I wonder, those white silent\r
+people we call the dead? Sibyl! Can she feel, or know, or listen?\r
+Oh, Harry, how I loved her once! It seems years ago to me now. She\r
+was everything to me. Then came that dreadful night--was it really\r
+only last night?--when she played so badly, and my heart almost broke.\r
+She explained it all to me. It was terribly pathetic. But I was not\r
+moved a bit. I thought her shallow. Suddenly something happened that\r
+made me afraid. I can't tell you what it was, but it was terrible. I\r
+said I would go back to her. I felt I had done wrong. And now she is\r
+dead. My God! My God! Harry, what shall I do? You don't know the\r
+danger I am in, and there is nothing to keep me straight. She would\r
+have done that for me. She had no right to kill herself. It was\r
+selfish of her."\r
+\r
+"My dear Dorian," answered Lord Henry, taking a cigarette from his case\r
+and producing a gold-latten matchbox, "the only way a woman can ever\r
+reform a man is by boring him so completely that he loses all possible\r
+interest in life. If you had married this girl, you would have been\r
+wretched. Of course, you would have treated her kindly. One can\r
+always be kind to people about whom one cares nothing. But she would\r
+have soon found out that you were absolutely indifferent to her. And\r
+when a woman finds that out about her husband, she either becomes\r
+dreadfully dowdy, or wears very smart bonnets that some other woman's\r
+husband has to pay for. I say nothing about the social mistake, which\r
+would have been abject--which, of course, I would not have allowed--but\r
+I assure you that in any case the whole thing would have been an\r
+absolute failure."\r
+\r
+"I suppose it would," muttered the lad, walking up and down the room\r
+and looking horribly pale. "But I thought it was my duty. It is not\r
+my fault that this terrible tragedy has prevented my doing what was\r
+right. I remember your saying once that there is a fatality about good\r
+resolutions--that they are always made too late. Mine certainly were."\r
+\r
+"Good resolutions are useless attempts to interfere with scientific\r
+laws. Their origin is pure vanity. Their result is absolutely _nil_.\r
+They give us, now and then, some of those luxurious sterile emotions\r
+that have a certain charm for the weak. That is all that can be said\r
+for them. They are simply cheques that men draw on a bank where they\r
+have no account."\r
+\r
+"Harry," cried Dorian Gray, coming over and sitting down beside him,\r
+"why is it that I cannot feel this tragedy as much as I want to? I\r
+don't think I am heartless. Do you?"\r
+\r
+"You have done too many foolish things during the last fortnight to be\r
+entitled to give yourself that name, Dorian," answered Lord Henry with\r
+his sweet melancholy smile.\r
+\r
+The lad frowned. "I don't like that explanation, Harry," he rejoined,\r
+"but I am glad you don't think I am heartless. I am nothing of the\r
+kind. I know I am not. And yet I must admit that this thing that has\r
+happened does not affect me as it should. It seems to me to be simply\r
+like a wonderful ending to a wonderful play. It has all the terrible\r
+beauty of a Greek tragedy, a tragedy in which I took a great part, but\r
+by which I have not been wounded."\r
+\r
+"It is an interesting question," said Lord Henry, who found an\r
+exquisite pleasure in playing on the lad's unconscious egotism, "an\r
+extremely interesting question. I fancy that the true explanation is\r
+this: It often happens that the real tragedies of life occur in such\r
+an inartistic manner that they hurt us by their crude violence, their\r
+absolute incoherence, their absurd want of meaning, their entire lack\r
+of style. They affect us just as vulgarity affects us. They give us\r
+an impression of sheer brute force, and we revolt against that.\r
+Sometimes, however, a tragedy that possesses artistic elements of\r
+beauty crosses our lives. If these elements of beauty are real, the\r
+whole thing simply appeals to our sense of dramatic effect. Suddenly\r
+we find that we are no longer the actors, but the spectators of the\r
+play. Or rather we are both. We watch ourselves, and the mere wonder\r
+of the spectacle enthralls us. In the present case, what is it that\r
+has really happened? Some one has killed herself for love of you. I\r
+wish that I had ever had such an experience. It would have made me in\r
+love with love for the rest of my life. The people who have adored\r
+me--there have not been very many, but there have been some--have\r
+always insisted on living on, long after I had ceased to care for them,\r
+or they to care for me. They have become stout and tedious, and when I\r
+meet them, they go in at once for reminiscences. That awful memory of\r
+woman! What a fearful thing it is! And what an utter intellectual\r
+stagnation it reveals! One should absorb the colour of life, but one\r
+should never remember its details. Details are always vulgar."\r
+\r
+"I must sow poppies in my garden," sighed Dorian.\r
+\r
+"There is no necessity," rejoined his companion. "Life has always\r
+poppies in her hands. Of course, now and then things linger. I once\r
+wore nothing but violets all through one season, as a form of artistic\r
+mourning for a romance that would not die. Ultimately, however, it did\r
+die. I forget what killed it. I think it was her proposing to\r
+sacrifice the whole world for me. That is always a dreadful moment.\r
+It fills one with the terror of eternity. Well--would you believe\r
+it?--a week ago, at Lady Hampshire's, I found myself seated at dinner\r
+next the lady in question, and she insisted on going over the whole\r
+thing again, and digging up the past, and raking up the future. I had\r
+buried my romance in a bed of asphodel. She dragged it out again and\r
+assured me that I had spoiled her life. I am bound to state that she\r
+ate an enormous dinner, so I did not feel any anxiety. But what a lack\r
+of taste she showed! The one charm of the past is that it is the past.\r
+But women never know when the curtain has fallen. They always want a\r
+sixth act, and as soon as the interest of the play is entirely over,\r
+they propose to continue it. If they were allowed their own way, every\r
+comedy would have a tragic ending, and every tragedy would culminate in\r
+a farce. They are charmingly artificial, but they have no sense of\r
+art. You are more fortunate than I am. I assure you, Dorian, that not\r
+one of the women I have known would have done for me what Sibyl Vane\r
+did for you. Ordinary women always console themselves. Some of them\r
+do it by going in for sentimental colours. Never trust a woman who\r
+wears mauve, whatever her age may be, or a woman over thirty-five who\r
+is fond of pink ribbons. It always means that they have a history.\r
+Others find a great consolation in suddenly discovering the good\r
+qualities of their husbands. They flaunt their conjugal felicity in\r
+one's face, as if it were the most fascinating of sins. Religion\r
+consoles some. Its mysteries have all the charm of a flirtation, a\r
+woman once told me, and I can quite understand it. Besides, nothing\r
+makes one so vain as being told that one is a sinner. Conscience makes\r
+egotists of us all. Yes; there is really no end to the consolations\r
+that women find in modern life. Indeed, I have not mentioned the most\r
+important one."\r
+\r
+"What is that, Harry?" said the lad listlessly.\r
+\r
+"Oh, the obvious consolation. Taking some one else's admirer when one\r
+loses one's own. In good society that always whitewashes a woman. But\r
+really, Dorian, how different Sibyl Vane must have been from all the\r
+women one meets! There is something to me quite beautiful about her\r
+death. I am glad I am living in a century when such wonders happen.\r
+They make one believe in the reality of the things we all play with,\r
+such as romance, passion, and love."\r
+\r
+"I was terribly cruel to her. You forget that."\r
+\r
+"I am afraid that women appreciate cruelty, downright cruelty, more\r
+than anything else. They have wonderfully primitive instincts. We\r
+have emancipated them, but they remain slaves looking for their\r
+masters, all the same. They love being dominated. I am sure you were\r
+splendid. I have never seen you really and absolutely angry, but I can\r
+fancy how delightful you looked. And, after all, you said something to\r
+me the day before yesterday that seemed to me at the time to be merely\r
+fanciful, but that I see now was absolutely true, and it holds the key\r
+to everything."\r
+\r
+"What was that, Harry?"\r
+\r
+"You said to me that Sibyl Vane represented to you all the heroines of\r
+romance--that she was Desdemona one night, and Ophelia the other; that\r
+if she died as Juliet, she came to life as Imogen."\r
+\r
+"She will never come to life again now," muttered the lad, burying his\r
+face in his hands.\r
+\r
+"No, she will never come to life. She has played her last part. But\r
+you must think of that lonely death in the tawdry dressing-room simply\r
+as a strange lurid fragment from some Jacobean tragedy, as a wonderful\r
+scene from Webster, or Ford, or Cyril Tourneur. The girl never really\r
+lived, and so she has never really died. To you at least she was\r
+always a dream, a phantom that flitted through Shakespeare's plays and\r
+left them lovelier for its presence, a reed through which Shakespeare's\r
+music sounded richer and more full of joy. The moment she touched\r
+actual life, she marred it, and it marred her, and so she passed away.\r
+Mourn for Ophelia, if you like. Put ashes on your head because\r
+Cordelia was strangled. Cry out against Heaven because the daughter of\r
+Brabantio died. But don't waste your tears over Sibyl Vane. She was\r
+less real than they are."\r
+\r
+There was a silence. The evening darkened in the room. Noiselessly,\r
+and with silver feet, the shadows crept in from the garden. The\r
+colours faded wearily out of things.\r
+\r
+After some time Dorian Gray looked up. "You have explained me to\r
+myself, Harry," he murmured with something of a sigh of relief. "I\r
+felt all that you have said, but somehow I was afraid of it, and I\r
+could not express it to myself. How well you know me! But we will not\r
+talk again of what has happened. It has been a marvellous experience.\r
+That is all. I wonder if life has still in store for me anything as\r
+marvellous."\r
+\r
+"Life has everything in store for you, Dorian. There is nothing that\r
+you, with your extraordinary good looks, will not be able to do."\r
+\r
+"But suppose, Harry, I became haggard, and old, and wrinkled? What\r
+then?"\r
+\r
+"Ah, then," said Lord Henry, rising to go, "then, my dear Dorian, you\r
+would have to fight for your victories. As it is, they are brought to\r
+you. No, you must keep your good looks. We live in an age that reads\r
+too much to be wise, and that thinks too much to be beautiful. We\r
+cannot spare you. And now you had better dress and drive down to the\r
+club. We are rather late, as it is."\r
+\r
+"I think I shall join you at the opera, Harry. I feel too tired to eat\r
+anything. What is the number of your sister's box?"\r
+\r
+"Twenty-seven, I believe. It is on the grand tier. You will see her\r
+name on the door. But I am sorry you won't come and dine."\r
+\r
+"I don't feel up to it," said Dorian listlessly. "But I am awfully\r
+obliged to you for all that you have said to me. You are certainly my\r
+best friend. No one has ever understood me as you have."\r
+\r
+"We are only at the beginning of our friendship, Dorian," answered Lord\r
+Henry, shaking him by the hand. "Good-bye. I shall see you before\r
+nine-thirty, I hope. Remember, Patti is singing."\r
+\r
+As he closed the door behind him, Dorian Gray touched the bell, and in\r
+a few minutes Victor appeared with the lamps and drew the blinds down.\r
+He waited impatiently for him to go. The man seemed to take an\r
+interminable time over everything.\r
+\r
+As soon as he had left, he rushed to the screen and drew it back. No;\r
+there was no further change in the picture. It had received the news\r
+of Sibyl Vane's death before he had known of it himself. It was\r
+conscious of the events of life as they occurred. The vicious cruelty\r
+that marred the fine lines of the mouth had, no doubt, appeared at the\r
+very moment that the girl had drunk the poison, whatever it was. Or\r
+was it indifferent to results? Did it merely take cognizance of what\r
+passed within the soul? He wondered, and hoped that some day he would\r
+see the change taking place before his very eyes, shuddering as he\r
+hoped it.\r
+\r
+Poor Sibyl! What a romance it had all been! She had often mimicked\r
+death on the stage. Then Death himself had touched her and taken her\r
+with him. How had she played that dreadful last scene? Had she cursed\r
+him, as she died? No; she had died for love of him, and love would\r
+always be a sacrament to him now. She had atoned for everything by the\r
+sacrifice she had made of her life. He would not think any more of\r
+what she had made him go through, on that horrible night at the\r
+theatre. When he thought of her, it would be as a wonderful tragic\r
+figure sent on to the world's stage to show the supreme reality of\r
+love. A wonderful tragic figure? Tears came to his eyes as he\r
+remembered her childlike look, and winsome fanciful ways, and shy\r
+tremulous grace. He brushed them away hastily and looked again at the\r
+picture.\r
+\r
+He felt that the time had really come for making his choice. Or had\r
+his choice already been made? Yes, life had decided that for\r
+him--life, and his own infinite curiosity about life. Eternal youth,\r
+infinite passion, pleasures subtle and secret, wild joys and wilder\r
+sins--he was to have all these things. The portrait was to bear the\r
+burden of his shame: that was all.\r
+\r
+A feeling of pain crept over him as he thought of the desecration that\r
+was in store for the fair face on the canvas. Once, in boyish mockery\r
+of Narcissus, he had kissed, or feigned to kiss, those painted lips\r
+that now smiled so cruelly at him. Morning after morning he had sat\r
+before the portrait wondering at its beauty, almost enamoured of it, as\r
+it seemed to him at times. Was it to alter now with every mood to\r
+which he yielded? Was it to become a monstrous and loathsome thing, to\r
+be hidden away in a locked room, to be shut out from the sunlight that\r
+had so often touched to brighter gold the waving wonder of its hair?\r
+The pity of it! the pity of it!\r
+\r
+For a moment, he thought of praying that the horrible sympathy that\r
+existed between him and the picture might cease. It had changed in\r
+answer to a prayer; perhaps in answer to a prayer it might remain\r
+unchanged. And yet, who, that knew anything about life, would\r
+surrender the chance of remaining always young, however fantastic that\r
+chance might be, or with what fateful consequences it might be fraught?\r
+Besides, was it really under his control? Had it indeed been prayer\r
+that had produced the substitution? Might there not be some curious\r
+scientific reason for it all? If thought could exercise its influence\r
+upon a living organism, might not thought exercise an influence upon\r
+dead and inorganic things? Nay, without thought or conscious desire,\r
+might not things external to ourselves vibrate in unison with our moods\r
+and passions, atom calling to atom in secret love or strange affinity?\r
+But the reason was of no importance. He would never again tempt by a\r
+prayer any terrible power. If the picture was to alter, it was to\r
+alter. That was all. Why inquire too closely into it?\r
+\r
+For there would be a real pleasure in watching it. He would be able to\r
+follow his mind into its secret places. This portrait would be to him\r
+the most magical of mirrors. As it had revealed to him his own body,\r
+so it would reveal to him his own soul. And when winter came upon it,\r
+he would still be standing where spring trembles on the verge of\r
+summer. When the blood crept from its face, and left behind a pallid\r
+mask of chalk with leaden eyes, he would keep the glamour of boyhood.\r
+Not one blossom of his loveliness would ever fade. Not one pulse of\r
+his life would ever weaken. Like the gods of the Greeks, he would be\r
+strong, and fleet, and joyous. What did it matter what happened to the\r
+coloured image on the canvas? He would be safe. That was everything.\r
+\r
+He drew the screen back into its former place in front of the picture,\r
+smiling as he did so, and passed into his bedroom, where his valet was\r
+already waiting for him. An hour later he was at the opera, and Lord\r
+Henry was leaning over his chair.\r
+\r
+\r
+\r
+CHAPTER 9\r
+\r
+As he was sitting at breakfast next morning, Basil Hallward was shown\r
+into the room.\r
+\r
+"I am so glad I have found you, Dorian," he said gravely. "I called\r
+last night, and they told me you were at the opera. Of course, I knew\r
+that was impossible. But I wish you had left word where you had really\r
+gone to. I passed a dreadful evening, half afraid that one tragedy\r
+might be followed by another. I think you might have telegraphed for\r
+me when you heard of it first. I read of it quite by chance in a late\r
+edition of _The Globe_ that I picked up at the club. I came here at once\r
+and was miserable at not finding you. I can't tell you how\r
+heart-broken I am about the whole thing. I know what you must suffer.\r
+But where were you? Did you go down and see the girl's mother? For a\r
+moment I thought of following you there. They gave the address in the\r
+paper. Somewhere in the Euston Road, isn't it? But I was afraid of\r
+intruding upon a sorrow that I could not lighten. Poor woman! What a\r
+state she must be in! And her only child, too! What did she say about\r
+it all?"\r
+\r
+"My dear Basil, how do I know?" murmured Dorian Gray, sipping some\r
+pale-yellow wine from a delicate, gold-beaded bubble of Venetian glass\r
+and looking dreadfully bored. "I was at the opera. You should have\r
+come on there. I met Lady Gwendolen, Harry's sister, for the first\r
+time. We were in her box. She is perfectly charming; and Patti sang\r
+divinely. Don't talk about horrid subjects. If one doesn't talk about\r
+a thing, it has never happened. It is simply expression, as Harry\r
+says, that gives reality to things. I may mention that she was not the\r
+woman's only child. There is a son, a charming fellow, I believe. But\r
+he is not on the stage. He is a sailor, or something. And now, tell\r
+me about yourself and what you are painting."\r
+\r
+"You went to the opera?" said Hallward, speaking very slowly and with a\r
+strained touch of pain in his voice. "You went to the opera while\r
+Sibyl Vane was lying dead in some sordid lodging? You can talk to me\r
+of other women being charming, and of Patti singing divinely, before\r
+the girl you loved has even the quiet of a grave to sleep in? Why,\r
+man, there are horrors in store for that little white body of hers!"\r
+\r
+"Stop, Basil! I won't hear it!" cried Dorian, leaping to his feet.\r
+"You must not tell me about things. What is done is done. What is\r
+past is past."\r
+\r
+"You call yesterday the past?"\r
+\r
+"What has the actual lapse of time got to do with it? It is only\r
+shallow people who require years to get rid of an emotion. A man who\r
+is master of himself can end a sorrow as easily as he can invent a\r
+pleasure. I don't want to be at the mercy of my emotions. I want to\r
+use them, to enjoy them, and to dominate them."\r
+\r
+"Dorian, this is horrible! Something has changed you completely. You\r
+look exactly the same wonderful boy who, day after day, used to come\r
+down to my studio to sit for his picture. But you were simple,\r
+natural, and affectionate then. You were the most unspoiled creature\r
+in the whole world. Now, I don't know what has come over you. You\r
+talk as if you had no heart, no pity in you. It is all Harry's\r
+influence. I see that."\r
+\r
+The lad flushed up and, going to the window, looked out for a few\r
+moments on the green, flickering, sun-lashed garden. "I owe a great\r
+deal to Harry, Basil," he said at last, "more than I owe to you. You\r
+only taught me to be vain."\r
+\r
+"Well, I am punished for that, Dorian--or shall be some day."\r
+\r
+"I don't know what you mean, Basil," he exclaimed, turning round. "I\r
+don't know what you want. What do you want?"\r
+\r
+"I want the Dorian Gray I used to paint," said the artist sadly.\r
+\r
+"Basil," said the lad, going over to him and putting his hand on his\r
+shoulder, "you have come too late. Yesterday, when I heard that Sibyl\r
+Vane had killed herself--"\r
+\r
+"Killed herself! Good heavens! is there no doubt about that?" cried\r
+Hallward, looking up at him with an expression of horror.\r
+\r
+"My dear Basil! Surely you don't think it was a vulgar accident? Of\r
+course she killed herself."\r
+\r
+The elder man buried his face in his hands. "How fearful," he\r
+muttered, and a shudder ran through him.\r
+\r
+"No," said Dorian Gray, "there is nothing fearful about it. It is one\r
+of the great romantic tragedies of the age. As a rule, people who act\r
+lead the most commonplace lives. They are good husbands, or faithful\r
+wives, or something tedious. You know what I mean--middle-class virtue\r
+and all that kind of thing. How different Sibyl was! She lived her\r
+finest tragedy. She was always a heroine. The last night she\r
+played--the night you saw her--she acted badly because she had known\r
+the reality of love. When she knew its unreality, she died, as Juliet\r
+might have died. She passed again into the sphere of art. There is\r
+something of the martyr about her. Her death has all the pathetic\r
+uselessness of martyrdom, all its wasted beauty. But, as I was saying,\r
+you must not think I have not suffered. If you had come in yesterday\r
+at a particular moment--about half-past five, perhaps, or a quarter to\r
+six--you would have found me in tears. Even Harry, who was here, who\r
+brought me the news, in fact, had no idea what I was going through. I\r
+suffered immensely. Then it passed away. I cannot repeat an emotion.\r
+No one can, except sentimentalists. And you are awfully unjust, Basil.\r
+You come down here to console me. That is charming of you. You find\r
+me consoled, and you are furious. How like a sympathetic person! You\r
+remind me of a story Harry told me about a certain philanthropist who\r
+spent twenty years of his life in trying to get some grievance\r
+redressed, or some unjust law altered--I forget exactly what it was.\r
+Finally he succeeded, and nothing could exceed his disappointment. He\r
+had absolutely nothing to do, almost died of _ennui_, and became a\r
+confirmed misanthrope. And besides, my dear old Basil, if you really\r
+want to console me, teach me rather to forget what has happened, or to\r
+see it from a proper artistic point of view. Was it not Gautier who\r
+used to write about _la consolation des arts_? I remember picking up a\r
+little vellum-covered book in your studio one day and chancing on that\r
+delightful phrase. Well, I am not like that young man you told me of\r
+when we were down at Marlow together, the young man who used to say\r
+that yellow satin could console one for all the miseries of life. I\r
+love beautiful things that one can touch and handle. Old brocades,\r
+green bronzes, lacquer-work, carved ivories, exquisite surroundings,\r
+luxury, pomp--there is much to be got from all these. But the artistic\r
+temperament that they create, or at any rate reveal, is still more to\r
+me. To become the spectator of one's own life, as Harry says, is to\r
+escape the suffering of life. I know you are surprised at my talking\r
+to you like this. You have not realized how I have developed. I was a\r
+schoolboy when you knew me. I am a man now. I have new passions, new\r
+thoughts, new ideas. I am different, but you must not like me less. I\r
+am changed, but you must always be my friend. Of course, I am very\r
+fond of Harry. But I know that you are better than he is. You are not\r
+stronger--you are too much afraid of life--but you are better. And how\r
+happy we used to be together! Don't leave me, Basil, and don't quarrel\r
+with me. I am what I am. There is nothing more to be said."\r
+\r
+The painter felt strangely moved. The lad was infinitely dear to him,\r
+and his personality had been the great turning point in his art. He\r
+could not bear the idea of reproaching him any more. After all, his\r
+indifference was probably merely a mood that would pass away. There\r
+was so much in him that was good, so much in him that was noble.\r
+\r
+"Well, Dorian," he said at length, with a sad smile, "I won't speak to\r
+you again about this horrible thing, after to-day. I only trust your\r
+name won't be mentioned in connection with it. The inquest is to take\r
+place this afternoon. Have they summoned you?"\r
+\r
+Dorian shook his head, and a look of annoyance passed over his face at\r
+the mention of the word "inquest." There was something so crude and\r
+vulgar about everything of the kind. "They don't know my name," he\r
+answered.\r
+\r
+"But surely she did?"\r
+\r
+"Only my Christian name, and that I am quite sure she never mentioned\r
+to any one. She told me once that they were all rather curious to\r
+learn who I was, and that she invariably told them my name was Prince\r
+Charming. It was pretty of her. You must do me a drawing of Sibyl,\r
+Basil. I should like to have something more of her than the memory of\r
+a few kisses and some broken pathetic words."\r
+\r
+"I will try and do something, Dorian, if it would please you. But you\r
+must come and sit to me yourself again. I can't get on without you."\r
+\r
+"I can never sit to you again, Basil. It is impossible!" he exclaimed,\r
+starting back.\r
+\r
+The painter stared at him. "My dear boy, what nonsense!" he cried.\r
+"Do you mean to say you don't like what I did of you? Where is it?\r
+Why have you pulled the screen in front of it? Let me look at it. It\r
+is the best thing I have ever done. Do take the screen away, Dorian.\r
+It is simply disgraceful of your servant hiding my work like that. I\r
+felt the room looked different as I came in."\r
+\r
+"My servant has nothing to do with it, Basil. You don't imagine I let\r
+him arrange my room for me? He settles my flowers for me\r
+sometimes--that is all. No; I did it myself. The light was too strong\r
+on the portrait."\r
+\r
+"Too strong! Surely not, my dear fellow? It is an admirable place for\r
+it. Let me see it." And Hallward walked towards the corner of the\r
+room.\r
+\r
+A cry of terror broke from Dorian Gray's lips, and he rushed between\r
+the painter and the screen. "Basil," he said, looking very pale, "you\r
+must not look at it. I don't wish you to."\r
+\r
+"Not look at my own work! You are not serious. Why shouldn't I look\r
+at it?" exclaimed Hallward, laughing.\r
+\r
+"If you try to look at it, Basil, on my word of honour I will never\r
+speak to you again as long as I live. I am quite serious. I don't\r
+offer any explanation, and you are not to ask for any. But, remember,\r
+if you touch this screen, everything is over between us."\r
+\r
+Hallward was thunderstruck. He looked at Dorian Gray in absolute\r
+amazement. He had never seen him like this before. The lad was\r
+actually pallid with rage. His hands were clenched, and the pupils of\r
+his eyes were like disks of blue fire. He was trembling all over.\r
+\r
+"Dorian!"\r
+\r
+"Don't speak!"\r
+\r
+"But what is the matter? Of course I won't look at it if you don't\r
+want me to," he said, rather coldly, turning on his heel and going over\r
+towards the window. "But, really, it seems rather absurd that I\r
+shouldn't see my own work, especially as I am going to exhibit it in\r
+Paris in the autumn. I shall probably have to give it another coat of\r
+varnish before that, so I must see it some day, and why not to-day?"\r
+\r
+"To exhibit it! You want to exhibit it?" exclaimed Dorian Gray, a\r
+strange sense of terror creeping over him. Was the world going to be\r
+shown his secret? Were people to gape at the mystery of his life?\r
+That was impossible. Something--he did not know what--had to be done\r
+at once.\r
+\r
+"Yes; I don't suppose you will object to that. Georges Petit is going\r
+to collect all my best pictures for a special exhibition in the Rue de\r
+Seze, which will open the first week in October. The portrait will\r
+only be away a month. I should think you could easily spare it for\r
+that time. In fact, you are sure to be out of town. And if you keep\r
+it always behind a screen, you can't care much about it."\r
+\r
+Dorian Gray passed his hand over his forehead. There were beads of\r
+perspiration there. He felt that he was on the brink of a horrible\r
+danger. "You told me a month ago that you would never exhibit it," he\r
+cried. "Why have you changed your mind? You people who go in for\r
+being consistent have just as many moods as others have. The only\r
+difference is that your moods are rather meaningless. You can't have\r
+forgotten that you assured me most solemnly that nothing in the world\r
+would induce you to send it to any exhibition. You told Harry exactly\r
+the same thing." He stopped suddenly, and a gleam of light came into\r
+his eyes. He remembered that Lord Henry had said to him once, half\r
+seriously and half in jest, "If you want to have a strange quarter of\r
+an hour, get Basil to tell you why he won't exhibit your picture. He\r
+told me why he wouldn't, and it was a revelation to me." Yes, perhaps\r
+Basil, too, had his secret. He would ask him and try.\r
+\r
+"Basil," he said, coming over quite close and looking him straight in\r
+the face, "we have each of us a secret. Let me know yours, and I shall\r
+tell you mine. What was your reason for refusing to exhibit my\r
+picture?"\r
+\r
+The painter shuddered in spite of himself. "Dorian, if I told you, you\r
+might like me less than you do, and you would certainly laugh at me. I\r
+could not bear your doing either of those two things. If you wish me\r
+never to look at your picture again, I am content. I have always you\r
+to look at. If you wish the best work I have ever done to be hidden\r
+from the world, I am satisfied. Your friendship is dearer to me than\r
+any fame or reputation."\r
+\r
+"No, Basil, you must tell me," insisted Dorian Gray. "I think I have a\r
+right to know." His feeling of terror had passed away, and curiosity\r
+had taken its place. He was determined to find out Basil Hallward's\r
+mystery.\r
+\r
+"Let us sit down, Dorian," said the painter, looking troubled. "Let us\r
+sit down. And just answer me one question. Have you noticed in the\r
+picture something curious?--something that probably at first did not\r
+strike you, but that revealed itself to you suddenly?"\r
+\r
+"Basil!" cried the lad, clutching the arms of his chair with trembling\r
+hands and gazing at him with wild startled eyes.\r
+\r
+"I see you did. Don't speak. Wait till you hear what I have to say.\r
+Dorian, from the moment I met you, your personality had the most\r
+extraordinary influence over me. I was dominated, soul, brain, and\r
+power, by you. You became to me the visible incarnation of that unseen\r
+ideal whose memory haunts us artists like an exquisite dream. I\r
+worshipped you. I grew jealous of every one to whom you spoke. I\r
+wanted to have you all to myself. I was only happy when I was with\r
+you. When you were away from me, you were still present in my art....\r
+Of course, I never let you know anything about this. It would have\r
+been impossible. You would not have understood it. I hardly\r
+understood it myself. I only knew that I had seen perfection face to\r
+face, and that the world had become wonderful to my eyes--too\r
+wonderful, perhaps, for in such mad worships there is peril, the peril\r
+of losing them, no less than the peril of keeping them.... Weeks and\r
+weeks went on, and I grew more and more absorbed in you. Then came a\r
+new development. I had drawn you as Paris in dainty armour, and as\r
+Adonis with huntsman's cloak and polished boar-spear. Crowned with\r
+heavy lotus-blossoms you had sat on the prow of Adrian's barge, gazing\r
+across the green turbid Nile. You had leaned over the still pool of\r
+some Greek woodland and seen in the water's silent silver the marvel of\r
+your own face. And it had all been what art should be--unconscious,\r
+ideal, and remote. One day, a fatal day I sometimes think, I\r
+determined to paint a wonderful portrait of you as you actually are,\r
+not in the costume of dead ages, but in your own dress and in your own\r
+time. Whether it was the realism of the method, or the mere wonder of\r
+your own personality, thus directly presented to me without mist or\r
+veil, I cannot tell. But I know that as I worked at it, every flake\r
+and film of colour seemed to me to reveal my secret. I grew afraid\r
+that others would know of my idolatry. I felt, Dorian, that I had told\r
+too much, that I had put too much of myself into it. Then it was that\r
+I resolved never to allow the picture to be exhibited. You were a\r
+little annoyed; but then you did not realize all that it meant to me.\r
+Harry, to whom I talked about it, laughed at me. But I did not mind\r
+that. When the picture was finished, and I sat alone with it, I felt\r
+that I was right.... Well, after a few days the thing left my studio,\r
+and as soon as I had got rid of the intolerable fascination of its\r
+presence, it seemed to me that I had been foolish in imagining that I\r
+had seen anything in it, more than that you were extremely good-looking\r
+and that I could paint. Even now I cannot help feeling that it is a\r
+mistake to think that the passion one feels in creation is ever really\r
+shown in the work one creates. Art is always more abstract than we\r
+fancy. Form and colour tell us of form and colour--that is all. It\r
+often seems to me that art conceals the artist far more completely than\r
+it ever reveals him. And so when I got this offer from Paris, I\r
+determined to make your portrait the principal thing in my exhibition.\r
+It never occurred to me that you would refuse. I see now that you were\r
+right. The picture cannot be shown. You must not be angry with me,\r
+Dorian, for what I have told you. As I said to Harry, once, you are\r
+made to be worshipped."\r
+\r
+Dorian Gray drew a long breath. The colour came back to his cheeks,\r
+and a smile played about his lips. The peril was over. He was safe\r
+for the time. Yet he could not help feeling infinite pity for the\r
+painter who had just made this strange confession to him, and wondered\r
+if he himself would ever be so dominated by the personality of a\r
+friend. Lord Henry had the charm of being very dangerous. But that\r
+was all. He was too clever and too cynical to be really fond of.\r
+Would there ever be some one who would fill him with a strange\r
+idolatry? Was that one of the things that life had in store?\r
+\r
+"It is extraordinary to me, Dorian," said Hallward, "that you should\r
+have seen this in the portrait. Did you really see it?"\r
+\r
+"I saw something in it," he answered, "something that seemed to me very\r
+curious."\r
+\r
+"Well, you don't mind my looking at the thing now?"\r
+\r
+Dorian shook his head. "You must not ask me that, Basil. I could not\r
+possibly let you stand in front of that picture."\r
+\r
+"You will some day, surely?"\r
+\r
+"Never."\r
+\r
+"Well, perhaps you are right. And now good-bye, Dorian. You have been\r
+the one person in my life who has really influenced my art. Whatever I\r
+have done that is good, I owe to you. Ah! you don't know what it cost\r
+me to tell you all that I have told you."\r
+\r
+"My dear Basil," said Dorian, "what have you told me? Simply that you\r
+felt that you admired me too much. That is not even a compliment."\r
+\r
+"It was not intended as a compliment. It was a confession. Now that I\r
+have made it, something seems to have gone out of me. Perhaps one\r
+should never put one's worship into words."\r
+\r
+"It was a very disappointing confession."\r
+\r
+"Why, what did you expect, Dorian? You didn't see anything else in the\r
+picture, did you? There was nothing else to see?"\r
+\r
+"No; there was nothing else to see. Why do you ask? But you mustn't\r
+talk about worship. It is foolish. You and I are friends, Basil, and\r
+we must always remain so."\r
+\r
+"You have got Harry," said the painter sadly.\r
+\r
+"Oh, Harry!" cried the lad, with a ripple of laughter. "Harry spends\r
+his days in saying what is incredible and his evenings in doing what is\r
+improbable. Just the sort of life I would like to lead. But still I\r
+don't think I would go to Harry if I were in trouble. I would sooner\r
+go to you, Basil."\r
+\r
+"You will sit to me again?"\r
+\r
+"Impossible!"\r
+\r
+"You spoil my life as an artist by refusing, Dorian. No man comes\r
+across two ideal things. Few come across one."\r
+\r
+"I can't explain it to you, Basil, but I must never sit to you again.\r
+There is something fatal about a portrait. It has a life of its own.\r
+I will come and have tea with you. That will be just as pleasant."\r
+\r
+"Pleasanter for you, I am afraid," murmured Hallward regretfully. "And\r
+now good-bye. I am sorry you won't let me look at the picture once\r
+again. But that can't be helped. I quite understand what you feel\r
+about it."\r
+\r
+As he left the room, Dorian Gray smiled to himself. Poor Basil! How\r
+little he knew of the true reason! And how strange it was that,\r
+instead of having been forced to reveal his own secret, he had\r
+succeeded, almost by chance, in wresting a secret from his friend! How\r
+much that strange confession explained to him! The painter's absurd\r
+fits of jealousy, his wild devotion, his extravagant panegyrics, his\r
+curious reticences--he understood them all now, and he felt sorry.\r
+There seemed to him to be something tragic in a friendship so coloured\r
+by romance.\r
+\r
+He sighed and touched the bell. The portrait must be hidden away at\r
+all costs. He could not run such a risk of discovery again. It had\r
+been mad of him to have allowed the thing to remain, even for an hour,\r
+in a room to which any of his friends had access.\r
+\r
+\r
+\r
+CHAPTER 10\r
+\r
+When his servant entered, he looked at him steadfastly and wondered if\r
+he had thought of peering behind the screen. The man was quite\r
+impassive and waited for his orders. Dorian lit a cigarette and walked\r
+over to the glass and glanced into it. He could see the reflection of\r
+Victor's face perfectly. It was like a placid mask of servility.\r
+There was nothing to be afraid of, there. Yet he thought it best to be\r
+on his guard.\r
+\r
+Speaking very slowly, he told him to tell the house-keeper that he\r
+wanted to see her, and then to go to the frame-maker and ask him to\r
+send two of his men round at once. It seemed to him that as the man\r
+left the room his eyes wandered in the direction of the screen. Or was\r
+that merely his own fancy?\r
+\r
+After a few moments, in her black silk dress, with old-fashioned thread\r
+mittens on her wrinkled hands, Mrs. Leaf bustled into the library. He\r
+asked her for the key of the schoolroom.\r
+\r
+"The old schoolroom, Mr. Dorian?" she exclaimed. "Why, it is full of\r
+dust. I must get it arranged and put straight before you go into it.\r
+It is not fit for you to see, sir. It is not, indeed."\r
+\r
+"I don't want it put straight, Leaf. I only want the key."\r
+\r
+"Well, sir, you'll be covered with cobwebs if you go into it. Why, it\r
+hasn't been opened for nearly five years--not since his lordship died."\r
+\r
+He winced at the mention of his grandfather. He had hateful memories\r
+of him. "That does not matter," he answered. "I simply want to see\r
+the place--that is all. Give me the key."\r
+\r
+"And here is the key, sir," said the old lady, going over the contents\r
+of her bunch with tremulously uncertain hands. "Here is the key. I'll\r
+have it off the bunch in a moment. But you don't think of living up\r
+there, sir, and you so comfortable here?"\r
+\r
+"No, no," he cried petulantly. "Thank you, Leaf. That will do."\r
+\r
+She lingered for a few moments, and was garrulous over some detail of\r
+the household. He sighed and told her to manage things as she thought\r
+best. She left the room, wreathed in smiles.\r
+\r
+As the door closed, Dorian put the key in his pocket and looked round\r
+the room. His eye fell on a large, purple satin coverlet heavily\r
+embroidered with gold, a splendid piece of late seventeenth-century\r
+Venetian work that his grandfather had found in a convent near Bologna.\r
+Yes, that would serve to wrap the dreadful thing in. It had perhaps\r
+served often as a pall for the dead. Now it was to hide something that\r
+had a corruption of its own, worse than the corruption of death\r
+itself--something that would breed horrors and yet would never die.\r
+What the worm was to the corpse, his sins would be to the painted image\r
+on the canvas. They would mar its beauty and eat away its grace. They\r
+would defile it and make it shameful. And yet the thing would still\r
+live on. It would be always alive.\r
+\r
+He shuddered, and for a moment he regretted that he had not told Basil\r
+the true reason why he had wished to hide the picture away. Basil\r
+would have helped him to resist Lord Henry's influence, and the still\r
+more poisonous influences that came from his own temperament. The love\r
+that he bore him--for it was really love--had nothing in it that was\r
+not noble and intellectual. It was not that mere physical admiration\r
+of beauty that is born of the senses and that dies when the senses\r
+tire. It was such love as Michelangelo had known, and Montaigne, and\r
+Winckelmann, and Shakespeare himself. Yes, Basil could have saved him.\r
+But it was too late now. The past could always be annihilated.\r
+Regret, denial, or forgetfulness could do that. But the future was\r
+inevitable. There were passions in him that would find their terrible\r
+outlet, dreams that would make the shadow of their evil real.\r
+\r
+He took up from the couch the great purple-and-gold texture that\r
+covered it, and, holding it in his hands, passed behind the screen.\r
+Was the face on the canvas viler than before? It seemed to him that it\r
+was unchanged, and yet his loathing of it was intensified. Gold hair,\r
+blue eyes, and rose-red lips--they all were there. It was simply the\r
+expression that had altered. That was horrible in its cruelty.\r
+Compared to what he saw in it of censure or rebuke, how shallow Basil's\r
+reproaches about Sibyl Vane had been!--how shallow, and of what little\r
+account! His own soul was looking out at him from the canvas and\r
+calling him to judgement. A look of pain came across him, and he flung\r
+the rich pall over the picture. As he did so, a knock came to the\r
+door. He passed out as his servant entered.\r
+\r
+"The persons are here, Monsieur."\r
+\r
+He felt that the man must be got rid of at once. He must not be\r
+allowed to know where the picture was being taken to. There was\r
+something sly about him, and he had thoughtful, treacherous eyes.\r
+Sitting down at the writing-table he scribbled a note to Lord Henry,\r
+asking him to send him round something to read and reminding him that\r
+they were to meet at eight-fifteen that evening.\r
+\r
+"Wait for an answer," he said, handing it to him, "and show the men in\r
+here."\r
+\r
+In two or three minutes there was another knock, and Mr. Hubbard\r
+himself, the celebrated frame-maker of South Audley Street, came in\r
+with a somewhat rough-looking young assistant. Mr. Hubbard was a\r
+florid, red-whiskered little man, whose admiration for art was\r
+considerably tempered by the inveterate impecuniosity of most of the\r
+artists who dealt with him. As a rule, he never left his shop. He\r
+waited for people to come to him. But he always made an exception in\r
+favour of Dorian Gray. There was something about Dorian that charmed\r
+everybody. It was a pleasure even to see him.\r
+\r
+"What can I do for you, Mr. Gray?" he said, rubbing his fat freckled\r
+hands. "I thought I would do myself the honour of coming round in\r
+person. I have just got a beauty of a frame, sir. Picked it up at a\r
+sale. Old Florentine. Came from Fonthill, I believe. Admirably\r
+suited for a religious subject, Mr. Gray."\r
+\r
+"I am so sorry you have given yourself the trouble of coming round, Mr.\r
+Hubbard. I shall certainly drop in and look at the frame--though I\r
+don't go in much at present for religious art--but to-day I only want a\r
+picture carried to the top of the house for me. It is rather heavy, so\r
+I thought I would ask you to lend me a couple of your men."\r
+\r
+"No trouble at all, Mr. Gray. I am delighted to be of any service to\r
+you. Which is the work of art, sir?"\r
+\r
+"This," replied Dorian, moving the screen back. "Can you move it,\r
+covering and all, just as it is? I don't want it to get scratched\r
+going upstairs."\r
+\r
+"There will be no difficulty, sir," said the genial frame-maker,\r
+beginning, with the aid of his assistant, to unhook the picture from\r
+the long brass chains by which it was suspended. "And, now, where\r
+shall we carry it to, Mr. Gray?"\r
+\r
+"I will show you the way, Mr. Hubbard, if you will kindly follow me.\r
+Or perhaps you had better go in front. I am afraid it is right at the\r
+top of the house. We will go up by the front staircase, as it is\r
+wider."\r
+\r
+He held the door open for them, and they passed out into the hall and\r
+began the ascent. The elaborate character of the frame had made the\r
+picture extremely bulky, and now and then, in spite of the obsequious\r
+protests of Mr. Hubbard, who had the true tradesman's spirited dislike\r
+of seeing a gentleman doing anything useful, Dorian put his hand to it\r
+so as to help them.\r
+\r
+"Something of a load to carry, sir," gasped the little man when they\r
+reached the top landing. And he wiped his shiny forehead.\r
+\r
+"I am afraid it is rather heavy," murmured Dorian as he unlocked the\r
+door that opened into the room that was to keep for him the curious\r
+secret of his life and hide his soul from the eyes of men.\r
+\r
+He had not entered the place for more than four years--not, indeed,\r
+since he had used it first as a play-room when he was a child, and then\r
+as a study when he grew somewhat older. It was a large,\r
+well-proportioned room, which had been specially built by the last Lord\r
+Kelso for the use of the little grandson whom, for his strange likeness\r
+to his mother, and also for other reasons, he had always hated and\r
+desired to keep at a distance. It appeared to Dorian to have but\r
+little changed. There was the huge Italian _cassone_, with its\r
+fantastically painted panels and its tarnished gilt mouldings, in which\r
+he had so often hidden himself as a boy. There the satinwood book-case\r
+filled with his dog-eared schoolbooks. On the wall behind it was\r
+hanging the same ragged Flemish tapestry where a faded king and queen\r
+were playing chess in a garden, while a company of hawkers rode by,\r
+carrying hooded birds on their gauntleted wrists. How well he\r
+remembered it all! Every moment of his lonely childhood came back to\r
+him as he looked round. He recalled the stainless purity of his boyish\r
+life, and it seemed horrible to him that it was here the fatal portrait\r
+was to be hidden away. How little he had thought, in those dead days,\r
+of all that was in store for him!\r
+\r
+But there was no other place in the house so secure from prying eyes as\r
+this. He had the key, and no one else could enter it. Beneath its\r
+purple pall, the face painted on the canvas could grow bestial, sodden,\r
+and unclean. What did it matter? No one could see it. He himself\r
+would not see it. Why should he watch the hideous corruption of his\r
+soul? He kept his youth--that was enough. And, besides, might not\r
+his nature grow finer, after all? There was no reason that the future\r
+should be so full of shame. Some love might come across his life, and\r
+purify him, and shield him from those sins that seemed to be already\r
+stirring in spirit and in flesh--those curious unpictured sins whose\r
+very mystery lent them their subtlety and their charm. Perhaps, some\r
+day, the cruel look would have passed away from the scarlet sensitive\r
+mouth, and he might show to the world Basil Hallward's masterpiece.\r
+\r
+No; that was impossible. Hour by hour, and week by week, the thing\r
+upon the canvas was growing old. It might escape the hideousness of\r
+sin, but the hideousness of age was in store for it. The cheeks would\r
+become hollow or flaccid. Yellow crow's feet would creep round the\r
+fading eyes and make them horrible. The hair would lose its\r
+brightness, the mouth would gape or droop, would be foolish or gross,\r
+as the mouths of old men are. There would be the wrinkled throat, the\r
+cold, blue-veined hands, the twisted body, that he remembered in the\r
+grandfather who had been so stern to him in his boyhood. The picture\r
+had to be concealed. There was no help for it.\r
+\r
+"Bring it in, Mr. Hubbard, please," he said, wearily, turning round.\r
+"I am sorry I kept you so long. I was thinking of something else."\r
+\r
+"Always glad to have a rest, Mr. Gray," answered the frame-maker, who\r
+was still gasping for breath. "Where shall we put it, sir?"\r
+\r
+"Oh, anywhere. Here: this will do. I don't want to have it hung up.\r
+Just lean it against the wall. Thanks."\r
+\r
+"Might one look at the work of art, sir?"\r
+\r
+Dorian started. "It would not interest you, Mr. Hubbard," he said,\r
+keeping his eye on the man. He felt ready to leap upon him and fling\r
+him to the ground if he dared to lift the gorgeous hanging that\r
+concealed the secret of his life. "I shan't trouble you any more now.\r
+I am much obliged for your kindness in coming round."\r
+\r
+"Not at all, not at all, Mr. Gray. Ever ready to do anything for you,\r
+sir." And Mr. Hubbard tramped downstairs, followed by the assistant,\r
+who glanced back at Dorian with a look of shy wonder in his rough\r
+uncomely face. He had never seen any one so marvellous.\r
+\r
+When the sound of their footsteps had died away, Dorian locked the door\r
+and put the key in his pocket. He felt safe now. No one would ever\r
+look upon the horrible thing. No eye but his would ever see his shame.\r
+\r
+On reaching the library, he found that it was just after five o'clock\r
+and that the tea had been already brought up. On a little table of\r
+dark perfumed wood thickly incrusted with nacre, a present from Lady\r
+Radley, his guardian's wife, a pretty professional invalid who had\r
+spent the preceding winter in Cairo, was lying a note from Lord Henry,\r
+and beside it was a book bound in yellow paper, the cover slightly torn\r
+and the edges soiled. A copy of the third edition of _The St. James's\r
+Gazette_ had been placed on the tea-tray. It was evident that Victor had\r
+returned. He wondered if he had met the men in the hall as they were\r
+leaving the house and had wormed out of them what they had been doing.\r
+He would be sure to miss the picture--had no doubt missed it already,\r
+while he had been laying the tea-things. The screen had not been set\r
+back, and a blank space was visible on the wall. Perhaps some night he\r
+might find him creeping upstairs and trying to force the door of the\r
+room. It was a horrible thing to have a spy in one's house. He had\r
+heard of rich men who had been blackmailed all their lives by some\r
+servant who had read a letter, or overheard a conversation, or picked\r
+up a card with an address, or found beneath a pillow a withered flower\r
+or a shred of crumpled lace.\r
+\r
+He sighed, and having poured himself out some tea, opened Lord Henry's\r
+note. It was simply to say that he sent him round the evening paper,\r
+and a book that might interest him, and that he would be at the club at\r
+eight-fifteen. He opened _The St. James's_ languidly, and looked through\r
+it. A red pencil-mark on the fifth page caught his eye. It drew\r
+attention to the following paragraph:\r
+\r
+\r
+INQUEST ON AN ACTRESS.--An inquest was held this morning at the Bell\r
+Tavern, Hoxton Road, by Mr. Danby, the District Coroner, on the body of\r
+Sibyl Vane, a young actress recently engaged at the Royal Theatre,\r
+Holborn. A verdict of death by misadventure was returned.\r
+Considerable sympathy was expressed for the mother of the deceased, who\r
+was greatly affected during the giving of her own evidence, and that of\r
+Dr. Birrell, who had made the post-mortem examination of the deceased.\r
+\r
+\r
+He frowned, and tearing the paper in two, went across the room and\r
+flung the pieces away. How ugly it all was! And how horribly real\r
+ugliness made things! He felt a little annoyed with Lord Henry for\r
+having sent him the report. And it was certainly stupid of him to have\r
+marked it with red pencil. Victor might have read it. The man knew\r
+more than enough English for that.\r
+\r
+Perhaps he had read it and had begun to suspect something. And, yet,\r
+what did it matter? What had Dorian Gray to do with Sibyl Vane's\r
+death? There was nothing to fear. Dorian Gray had not killed her.\r
+\r
+His eye fell on the yellow book that Lord Henry had sent him. What was\r
+it, he wondered. He went towards the little, pearl-coloured octagonal\r
+stand that had always looked to him like the work of some strange\r
+Egyptian bees that wrought in silver, and taking up the volume, flung\r
+himself into an arm-chair and began to turn over the leaves. After a\r
+few minutes he became absorbed. It was the strangest book that he had\r
+ever read. It seemed to him that in exquisite raiment, and to the\r
+delicate sound of flutes, the sins of the world were passing in dumb\r
+show before him. Things that he had dimly dreamed of were suddenly\r
+made real to him. Things of which he had never dreamed were gradually\r
+revealed.\r
+\r
+It was a novel without a plot and with only one character, being,\r
+indeed, simply a psychological study of a certain young Parisian who\r
+spent his life trying to realize in the nineteenth century all the\r
+passions and modes of thought that belonged to every century except his\r
+own, and to sum up, as it were, in himself the various moods through\r
+which the world-spirit had ever passed, loving for their mere\r
+artificiality those renunciations that men have unwisely called virtue,\r
+as much as those natural rebellions that wise men still call sin. The\r
+style in which it was written was that curious jewelled style, vivid\r
+and obscure at once, full of _argot_ and of archaisms, of technical\r
+expressions and of elaborate paraphrases, that characterizes the work\r
+of some of the finest artists of the French school of _Symbolistes_.\r
+There were in it metaphors as monstrous as orchids and as subtle in\r
+colour. The life of the senses was described in the terms of mystical\r
+philosophy. One hardly knew at times whether one was reading the\r
+spiritual ecstasies of some mediaeval saint or the morbid confessions\r
+of a modern sinner. It was a poisonous book. The heavy odour of\r
+incense seemed to cling about its pages and to trouble the brain. The\r
+mere cadence of the sentences, the subtle monotony of their music, so\r
+full as it was of complex refrains and movements elaborately repeated,\r
+produced in the mind of the lad, as he passed from chapter to chapter,\r
+a form of reverie, a malady of dreaming, that made him unconscious of\r
+the falling day and creeping shadows.\r
+\r
+Cloudless, and pierced by one solitary star, a copper-green sky gleamed\r
+through the windows. He read on by its wan light till he could read no\r
+more. Then, after his valet had reminded him several times of the\r
+lateness of the hour, he got up, and going into the next room, placed\r
+the book on the little Florentine table that always stood at his\r
+bedside and began to dress for dinner.\r
+\r
+It was almost nine o'clock before he reached the club, where he found\r
+Lord Henry sitting alone, in the morning-room, looking very much bored.\r
+\r
+"I am so sorry, Harry," he cried, "but really it is entirely your\r
+fault. That book you sent me so fascinated me that I forgot how the\r
+time was going."\r
+\r
+"Yes, I thought you would like it," replied his host, rising from his\r
+chair.\r
+\r
+"I didn't say I liked it, Harry. I said it fascinated me. There is a\r
+great difference."\r
+\r
+"Ah, you have discovered that?" murmured Lord Henry. And they passed\r
+into the dining-room.\r
+\r

+\r
+CHAPTER 11\r
+\r
+For years, Dorian Gray could not free himself from the influence of\r
+this book. Or perhaps it would be more accurate to say that he never\r
+sought to free himself from it. He procured from Paris no less than\r
+nine large-paper copies of the first edition, and had them bound in\r
+different colours, so that they might suit his various moods and the\r
+changing fancies of a nature over which he seemed, at times, to have\r
+almost entirely lost control. The hero, the wonderful young Parisian\r
+in whom the romantic and the scientific temperaments were so strangely\r
+blended, became to him a kind of prefiguring type of himself. And,\r
+indeed, the whole book seemed to him to contain the story of his own\r
+life, written before he had lived it.\r
+\r
+In one point he was more fortunate than the novel's fantastic hero. He\r
+never knew--never, indeed, had any cause to know--that somewhat\r
+grotesque dread of mirrors, and polished metal surfaces, and still\r
+water which came upon the young Parisian so early in his life, and was\r
+occasioned by the sudden decay of a beau that had once, apparently,\r
+been so remarkable. It was with an almost cruel joy--and perhaps in\r
+nearly every joy, as certainly in every pleasure, cruelty has its\r
+place--that he used to read the latter part of the book, with its\r
+really tragic, if somewhat overemphasized, account of the sorrow and\r
+despair of one who had himself lost what in others, and the world, he\r
+had most dearly valued.\r
+\r
+For the wonderful beauty that had so fascinated Basil Hallward, and\r
+many others besides him, seemed never to leave him. Even those who had\r
+heard the most evil things against him--and from time to time strange\r
+rumours about his mode of life crept through London and became the\r
+chatter of the clubs--could not believe anything to his dishonour when\r
+they saw him. He had always the look of one who had kept himself\r
+unspotted from the world. Men who talked grossly became silent when\r
+Dorian Gray entered the room. There was something in the purity of his\r
+face that rebuked them. His mere presence seemed to recall to them the\r
+memory of the innocence that they had tarnished. They wondered how one\r
+so charming and graceful as he was could have escaped the stain of an\r
+age that was at once sordid and sensual.\r
+\r
+Often, on returning home from one of those mysterious and prolonged\r
+absences that gave rise to such strange conjecture among those who were\r
+his friends, or thought that they were so, he himself would creep\r
+upstairs to the locked room, open the door with the key that never left\r
+him now, and stand, with a mirror, in front of the portrait that Basil\r
+Hallward had painted of him, looking now at the evil and aging face on\r
+the canvas, and now at the fair young face that laughed back at him\r
+from the polished glass. The very sharpness of the contrast used to\r
+quicken his sense of pleasure. He grew more and more enamoured of his\r
+own beauty, more and more interested in the corruption of his own soul.\r
+He would examine with minute care, and sometimes with a monstrous and\r
+terrible delight, the hideous lines that seared the wrinkling forehead\r
+or crawled around the heavy sensual mouth, wondering sometimes which\r
+were the more horrible, the signs of sin or the signs of age. He would\r
+place his white hands beside the coarse bloated hands of the picture,\r
+and smile. He mocked the misshapen body and the failing limbs.\r
+\r
+There were moments, indeed, at night, when, lying sleepless in his own\r
+delicately scented chamber, or in the sordid room of the little\r
+ill-famed tavern near the docks which, under an assumed name and in\r
+disguise, it was his habit to frequent, he would think of the ruin he\r
+had brought upon his soul with a pity that was all the more poignant\r
+because it was purely selfish. But moments such as these were rare.\r
+That curiosity about life which Lord Henry had first stirred in him, as\r
+they sat together in the garden of their friend, seemed to increase\r
+with gratification. The more he knew, the more he desired to know. He\r
+had mad hungers that grew more ravenous as he fed them.\r
+\r
+Yet he was not really reckless, at any rate in his relations to\r
+society. Once or twice every month during the winter, and on each\r
+Wednesday evening while the season lasted, he would throw open to the\r
+world his beautiful house and have the most celebrated musicians of the\r
+day to charm his guests with the wonders of their art. His little\r
+dinners, in the settling of which Lord Henry always assisted him, were\r
+noted as much for the careful selection and placing of those invited,\r
+as for the exquisite taste shown in the decoration of the table, with\r
+its subtle symphonic arrangements of exotic flowers, and embroidered\r
+cloths, and antique plate of gold and silver. Indeed, there were many,\r
+especially among the very young men, who saw, or fancied that they saw,\r
+in Dorian Gray the true realization of a type of which they had often\r
+dreamed in Eton or Oxford days, a type that was to combine something of\r
+the real culture of the scholar with all the grace and distinction and\r
+perfect manner of a citizen of the world. To them he seemed to be of\r
+the company of those whom Dante describes as having sought to "make\r
+themselves perfect by the worship of beauty." Like Gautier, he was one\r
+for whom "the visible world existed."\r
+\r
+And, certainly, to him life itself was the first, the greatest, of the\r
+arts, and for it all the other arts seemed to be but a preparation.\r
+Fashion, by which what is really fantastic becomes for a moment\r
+universal, and dandyism, which, in its own way, is an attempt to assert\r
+the absolute modernity of beauty, had, of course, their fascination for\r
+him. His mode of dressing, and the particular styles that from time to\r
+time he affected, had their marked influence on the young exquisites of\r
+the Mayfair balls and Pall Mall club windows, who copied him in\r
+everything that he did, and tried to reproduce the accidental charm of\r
+his graceful, though to him only half-serious, fopperies.\r
+\r
+For, while he was but too ready to accept the position that was almost\r
+immediately offered to him on his coming of age, and found, indeed, a\r
+subtle pleasure in the thought that he might really become to the\r
+London of his own day what to imperial Neronian Rome the author of the\r
+Satyricon once had been, yet in his inmost heart he desired to be\r
+something more than a mere _arbiter elegantiarum_, to be consulted on the\r
+wearing of a jewel, or the knotting of a necktie, or the conduct of a\r
+cane. He sought to elaborate some new scheme of life that would have\r
+its reasoned philosophy and its ordered principles, and find in the\r
+spiritualizing of the senses its highest realization.\r
+\r
+The worship of the senses has often, and with much justice, been\r
+decried, men feeling a natural instinct of terror about passions and\r
+sensations that seem stronger than themselves, and that they are\r
+conscious of sharing with the less highly organized forms of existence.\r
+But it appeared to Dorian Gray that the true nature of the senses had\r
+never been understood, and that they had remained savage and animal\r
+merely because the world had sought to starve them into submission or\r
+to kill them by pain, instead of aiming at making them elements of a\r
+new spirituality, of which a fine instinct for beauty was to be the\r
+dominant characteristic. As he looked back upon man moving through\r
+history, he was haunted by a feeling of loss. So much had been\r
+surrendered! and to such little purpose! There had been mad wilful\r
+rejections, monstrous forms of self-torture and self-denial, whose\r
+origin was fear and whose result was a degradation infinitely more\r
+terrible than that fancied degradation from which, in their ignorance,\r
+they had sought to escape; Nature, in her wonderful irony, driving out\r
+the anchorite to feed with the wild animals of the desert and giving to\r
+the hermit the beasts of the field as his companions.\r
+\r
+Yes: there was to be, as Lord Henry had prophesied, a new Hedonism\r
+that was to recreate life and to save it from that harsh uncomely\r
+puritanism that is having, in our own day, its curious revival. It was\r
+to have its service of the intellect, certainly, yet it was never to\r
+accept any theory or system that would involve the sacrifice of any\r
+mode of passionate experience. Its aim, indeed, was to be experience\r
+itself, and not the fruits of experience, sweet or bitter as they might\r
+be. Of the asceticism that deadens the senses, as of the vulgar\r
+profligacy that dulls them, it was to know nothing. But it was to\r
+teach man to concentrate himself upon the moments of a life that is\r
+itself but a moment.\r
+\r
+There are few of us who have not sometimes wakened before dawn, either\r
+after one of those dreamless nights that make us almost enamoured of\r
+death, or one of those nights of horror and misshapen joy, when through\r
+the chambers of the brain sweep phantoms more terrible than reality\r
+itself, and instinct with that vivid life that lurks in all grotesques,\r
+and that lends to Gothic art its enduring vitality, this art being, one\r
+might fancy, especially the art of those whose minds have been troubled\r
+with the malady of reverie. Gradually white fingers creep through the\r
+curtains, and they appear to tremble. In black fantastic shapes, dumb\r
+shadows crawl into the corners of the room and crouch there. Outside,\r
+there is the stirring of birds among the leaves, or the sound of men\r
+going forth to their work, or the sigh and sob of the wind coming down\r
+from the hills and wandering round the silent house, as though it\r
+feared to wake the sleepers and yet must needs call forth sleep from\r
+her purple cave. Veil after veil of thin dusky gauze is lifted, and by\r
+degrees the forms and colours of things are restored to them, and we\r
+watch the dawn remaking the world in its antique pattern. The wan\r
+mirrors get back their mimic life. The flameless tapers stand where we\r
+had left them, and beside them lies the half-cut book that we had been\r
+studying, or the wired flower that we had worn at the ball, or the\r
+letter that we had been afraid to read, or that we had read too often.\r
+Nothing seems to us changed. Out of the unreal shadows of the night\r
+comes back the real life that we had known. We have to resume it where\r
+we had left off, and there steals over us a terrible sense of the\r
+necessity for the continuance of energy in the same wearisome round of\r
+stereotyped habits, or a wild longing, it may be, that our eyelids\r
+might open some morning upon a world that had been refashioned anew in\r
+the darkness for our pleasure, a world in which things would have fresh\r
+shapes and colours, and be changed, or have other secrets, a world in\r
+which the past would have little or no place, or survive, at any rate,\r
+in no conscious form of obligation or regret, the remembrance even of\r
+joy having its bitterness and the memories of pleasure their pain.\r
+\r
+It was the creation of such worlds as these that seemed to Dorian Gray\r
+to be the true object, or amongst the true objects, of life; and in his\r
+search for sensations that would be at once new and delightful, and\r
+possess that element of strangeness that is so essential to romance, he\r
+would often adopt certain modes of thought that he knew to be really\r
+alien to his nature, abandon himself to their subtle influences, and\r
+then, having, as it were, caught their colour and satisfied his\r
+intellectual curiosity, leave them with that curious indifference that\r
+is not incompatible with a real ardour of temperament, and that,\r
+indeed, according to certain modern psychologists, is often a condition\r
+of it.\r
+\r
+It was rumoured of him once that he was about to join the Roman\r
+Catholic communion, and certainly the Roman ritual had always a great\r
+attraction for him. The daily sacrifice, more awful really than all\r
+the sacrifices of the antique world, stirred him as much by its superb\r
+rejection of the evidence of the senses as by the primitive simplicity\r
+of its elements and the eternal pathos of the human tragedy that it\r
+sought to symbolize. He loved to kneel down on the cold marble\r
+pavement and watch the priest, in his stiff flowered dalmatic, slowly\r
+and with white hands moving aside the veil of the tabernacle, or\r
+raising aloft the jewelled, lantern-shaped monstrance with that pallid\r
+wafer that at times, one would fain think, is indeed the "_panis\r
+caelestis_," the bread of angels, or, robed in the garments of the\r
+Passion of Christ, breaking the Host into the chalice and smiting his\r
+breast for his sins. The fuming censers that the grave boys, in their\r
+lace and scarlet, tossed into the air like great gilt flowers had their\r
+subtle fascination for him. As he passed out, he used to look with\r
+wonder at the black confessionals and long to sit in the dim shadow of\r
+one of them and listen to men and women whispering through the worn\r
+grating the true story of their lives.\r
+\r
+But he never fell into the error of arresting his intellectual\r
+development by any formal acceptance of creed or system, or of\r
+mistaking, for a house in which to live, an inn that is but suitable\r
+for the sojourn of a night, or for a few hours of a night in which\r
+there are no stars and the moon is in travail. Mysticism, with its\r
+marvellous power of making common things strange to us, and the subtle\r
+antinomianism that always seems to accompany it, moved him for a\r
+season; and for a season he inclined to the materialistic doctrines of\r
+the _Darwinismus_ movement in Germany, and found a curious pleasure in\r
+tracing the thoughts and passions of men to some pearly cell in the\r
+brain, or some white nerve in the body, delighting in the conception of\r
+the absolute dependence of the spirit on certain physical conditions,\r
+morbid or healthy, normal or diseased. Yet, as has been said of him\r
+before, no theory of life seemed to him to be of any importance\r
+compared with life itself. He felt keenly conscious of how barren all\r
+intellectual speculation is when separated from action and experiment.\r
+He knew that the senses, no less than the soul, have their spiritual\r
+mysteries to reveal.\r
+\r
+And so he would now study perfumes and the secrets of their\r
+manufacture, distilling heavily scented oils and burning odorous gums\r
+from the East. He saw that there was no mood of the mind that had not\r
+its counterpart in the sensuous life, and set himself to discover their\r
+true relations, wondering what there was in frankincense that made one\r
+mystical, and in ambergris that stirred one's passions, and in violets\r
+that woke the memory of dead romances, and in musk that troubled the\r
+brain, and in champak that stained the imagination; and seeking often\r
+to elaborate a real psychology of perfumes, and to estimate the several\r
+influences of sweet-smelling roots and scented, pollen-laden flowers;\r
+of aromatic balms and of dark and fragrant woods; of spikenard, that\r
+sickens; of hovenia, that makes men mad; and of aloes, that are said to\r
+be able to expel melancholy from the soul.\r
+\r
+At another time he devoted himself entirely to music, and in a long\r
+latticed room, with a vermilion-and-gold ceiling and walls of\r
+olive-green lacquer, he used to give curious concerts in which mad\r
+gipsies tore wild music from little zithers, or grave, yellow-shawled\r
+Tunisians plucked at the strained strings of monstrous lutes, while\r
+grinning Negroes beat monotonously upon copper drums and, crouching\r
+upon scarlet mats, slim turbaned Indians blew through long pipes of\r
+reed or brass and charmed--or feigned to charm--great hooded snakes and\r
+horrible horned adders. The harsh intervals and shrill discords of\r
+barbaric music stirred him at times when Schubert's grace, and Chopin's\r
+beautiful sorrows, and the mighty harmonies of Beethoven himself, fell\r
+unheeded on his ear. He collected together from all parts of the world\r
+the strangest instruments that could be found, either in the tombs of\r
+dead nations or among the few savage tribes that have survived contact\r
+with Western civilizations, and loved to touch and try them. He had\r
+the mysterious _juruparis_ of the Rio Negro Indians, that women are not\r
+allowed to look at and that even youths may not see till they have been\r
+subjected to fasting and scourging, and the earthen jars of the\r
+Peruvians that have the shrill cries of birds, and flutes of human\r
+bones such as Alfonso de Ovalle heard in Chile, and the sonorous green\r
+jaspers that are found near Cuzco and give forth a note of singular\r
+sweetness. He had painted gourds filled with pebbles that rattled when\r
+they were shaken; the long _clarin_ of the Mexicans, into which the\r
+performer does not blow, but through which he inhales the air; the\r
+harsh _ture_ of the Amazon tribes, that is sounded by the sentinels who\r
+sit all day long in high trees, and can be heard, it is said, at a\r
+distance of three leagues; the _teponaztli_, that has two vibrating\r
+tongues of wood and is beaten with sticks that are smeared with an\r
+elastic gum obtained from the milky juice of plants; the _yotl_-bells of\r
+the Aztecs, that are hung in clusters like grapes; and a huge\r
+cylindrical drum, covered with the skins of great serpents, like the\r
+one that Bernal Diaz saw when he went with Cortes into the Mexican\r
+temple, and of whose doleful sound he has left us so vivid a\r
+description. The fantastic character of these instruments fascinated\r
+him, and he felt a curious delight in the thought that art, like\r
+Nature, has her monsters, things of bestial shape and with hideous\r
+voices. Yet, after some time, he wearied of them, and would sit in his\r
+box at the opera, either alone or with Lord Henry, listening in rapt\r
+pleasure to "Tannhauser" and seeing in the prelude to that great work\r
+of art a presentation of the tragedy of his own soul.\r
+\r
+On one occasion he took up the study of jewels, and appeared at a\r
+costume ball as Anne de Joyeuse, Admiral of France, in a dress covered\r
+with five hundred and sixty pearls. This taste enthralled him for\r
+years, and, indeed, may be said never to have left him. He would often\r
+spend a whole day settling and resettling in their cases the various\r
+stones that he had collected, such as the olive-green chrysoberyl that\r
+turns red by lamplight, the cymophane with its wirelike line of silver,\r
+the pistachio-coloured peridot, rose-pink and wine-yellow topazes,\r
+carbuncles of fiery scarlet with tremulous, four-rayed stars, flame-red\r
+cinnamon-stones, orange and violet spinels, and amethysts with their\r
+alternate layers of ruby and sapphire. He loved the red gold of the\r
+sunstone, and the moonstone's pearly whiteness, and the broken rainbow\r
+of the milky opal. He procured from Amsterdam three emeralds of\r
+extraordinary size and richness of colour, and had a turquoise _de la\r
+vieille roche_ that was the envy of all the connoisseurs.\r
+\r
+He discovered wonderful stories, also, about jewels. In Alphonso's\r
+Clericalis Disciplina a serpent was mentioned with eyes of real\r
+jacinth, and in the romantic history of Alexander, the Conqueror of\r
+Emathia was said to have found in the vale of Jordan snakes "with\r
+collars of real emeralds growing on their backs." There was a gem in\r
+the brain of the dragon, Philostratus told us, and "by the exhibition\r
+of golden letters and a scarlet robe" the monster could be thrown into\r
+a magical sleep and slain. According to the great alchemist, Pierre de\r
+Boniface, the diamond rendered a man invisible, and the agate of India\r
+made him eloquent. The cornelian appeased anger, and the hyacinth\r
+provoked sleep, and the amethyst drove away the fumes of wine. The\r
+garnet cast out demons, and the hydropicus deprived the moon of her\r
+colour. The selenite waxed and waned with the moon, and the meloceus,\r
+that discovers thieves, could be affected only by the blood of kids.\r
+Leonardus Camillus had seen a white stone taken from the brain of a\r
+newly killed toad, that was a certain antidote against poison. The\r
+bezoar, that was found in the heart of the Arabian deer, was a charm\r
+that could cure the plague. In the nests of Arabian birds was the\r
+aspilates, that, according to Democritus, kept the wearer from any\r
+danger by fire.\r
+\r
+The King of Ceilan rode through his city with a large ruby in his hand,\r
+as the ceremony of his coronation. The gates of the palace of John the\r
+Priest were "made of sardius, with the horn of the horned snake\r
+inwrought, so that no man might bring poison within." Over the gable\r
+were "two golden apples, in which were two carbuncles," so that the\r
+gold might shine by day and the carbuncles by night. In Lodge's\r
+strange romance 'A Margarite of America', it was stated that in the\r
+chamber of the queen one could behold "all the chaste ladies of the\r
+world, inchased out of silver, looking through fair mirrours of\r
+chrysolites, carbuncles, sapphires, and greene emeraults." Marco Polo\r
+had seen the inhabitants of Zipangu place rose-coloured pearls in the\r
+mouths of the dead. A sea-monster had been enamoured of the pearl that\r
+the diver brought to King Perozes, and had slain the thief, and mourned\r
+for seven moons over its loss. When the Huns lured the king into the\r
+great pit, he flung it away--Procopius tells the story--nor was it ever\r
+found again, though the Emperor Anastasius offered five hundred-weight\r
+of gold pieces for it. The King of Malabar had shown to a certain\r
+Venetian a rosary of three hundred and four pearls, one for every god\r
+that he worshipped.\r
+\r
+When the Duke de Valentinois, son of Alexander VI, visited Louis XII of\r
+France, his horse was loaded with gold leaves, according to Brantome,\r
+and his cap had double rows of rubies that threw out a great light.\r
+Charles of England had ridden in stirrups hung with four hundred and\r
+twenty-one diamonds. Richard II had a coat, valued at thirty thousand\r
+marks, which was covered with balas rubies. Hall described Henry VIII,\r
+on his way to the Tower previous to his coronation, as wearing "a\r
+jacket of raised gold, the placard embroidered with diamonds and other\r
+rich stones, and a great bauderike about his neck of large balasses."\r
+The favourites of James I wore ear-rings of emeralds set in gold\r
+filigrane. Edward II gave to Piers Gaveston a suit of red-gold armour\r
+studded with jacinths, a collar of gold roses set with\r
+turquoise-stones, and a skull-cap _parseme_ with pearls. Henry II wore\r
+jewelled gloves reaching to the elbow, and had a hawk-glove sewn with\r
+twelve rubies and fifty-two great orients. The ducal hat of Charles\r
+the Rash, the last Duke of Burgundy of his race, was hung with\r
+pear-shaped pearls and studded with sapphires.\r
+\r
+How exquisite life had once been! How gorgeous in its pomp and\r
+decoration! Even to read of the luxury of the dead was wonderful.\r
+\r
+Then he turned his attention to embroideries and to the tapestries that\r
+performed the office of frescoes in the chill rooms of the northern\r
+nations of Europe. As he investigated the subject--and he always had\r
+an extraordinary faculty of becoming absolutely absorbed for the moment\r
+in whatever he took up--he was almost saddened by the reflection of the\r
+ruin that time brought on beautiful and wonderful things. He, at any\r
+rate, had escaped that. Summer followed summer, and the yellow\r
+jonquils bloomed and died many times, and nights of horror repeated the\r
+story of their shame, but he was unchanged. No winter marred his face\r
+or stained his flowerlike bloom. How different it was with material\r
+things! Where had they passed to? Where was the great crocus-coloured\r
+robe, on which the gods fought against the giants, that had been worked\r
+by brown girls for the pleasure of Athena? Where the huge velarium\r
+that Nero had stretched across the Colosseum at Rome, that Titan sail\r
+of purple on which was represented the starry sky, and Apollo driving a\r
+chariot drawn by white, gilt-reined steeds? He longed to see the\r
+curious table-napkins wrought for the Priest of the Sun, on which were\r
+displayed all the dainties and viands that could be wanted for a feast;\r
+the mortuary cloth of King Chilperic, with its three hundred golden\r
+bees; the fantastic robes that excited the indignation of the Bishop of\r
+Pontus and were figured with "lions, panthers, bears, dogs, forests,\r
+rocks, hunters--all, in fact, that a painter can copy from nature"; and\r
+the coat that Charles of Orleans once wore, on the sleeves of which\r
+were embroidered the verses of a song beginning "_Madame, je suis tout\r
+joyeux_," the musical accompaniment of the words being wrought in gold\r
+thread, and each note, of square shape in those days, formed with four\r
+pearls. He read of the room that was prepared at the palace at Rheims\r
+for the use of Queen Joan of Burgundy and was decorated with "thirteen\r
+hundred and twenty-one parrots, made in broidery, and blazoned with the\r
+king's arms, and five hundred and sixty-one butterflies, whose wings\r
+were similarly ornamented with the arms of the queen, the whole worked\r
+in gold." Catherine de Medicis had a mourning-bed made for her of\r
+black velvet powdered with crescents and suns. Its curtains were of\r
+damask, with leafy wreaths and garlands, figured upon a gold and silver\r
+ground, and fringed along the edges with broideries of pearls, and it\r
+stood in a room hung with rows of the queen's devices in cut black\r
+velvet upon cloth of silver. Louis XIV had gold embroidered caryatides\r
+fifteen feet high in his apartment. The state bed of Sobieski, King of\r
+Poland, was made of Smyrna gold brocade embroidered in turquoises with\r
+verses from the Koran. Its supports were of silver gilt, beautifully\r
+chased, and profusely set with enamelled and jewelled medallions. It\r
+had been taken from the Turkish camp before Vienna, and the standard of\r
+Mohammed had stood beneath the tremulous gilt of its canopy.\r
+\r
+And so, for a whole year, he sought to accumulate the most exquisite\r
+specimens that he could find of textile and embroidered work, getting\r
+the dainty Delhi muslins, finely wrought with gold-thread palmates and\r
+stitched over with iridescent beetles' wings; the Dacca gauzes, that\r
+from their transparency are known in the East as "woven air," and\r
+"running water," and "evening dew"; strange figured cloths from Java;\r
+elaborate yellow Chinese hangings; books bound in tawny satins or fair\r
+blue silks and wrought with _fleurs-de-lis_, birds and images; veils of\r
+_lacis_ worked in Hungary point; Sicilian brocades and stiff Spanish\r
+velvets; Georgian work, with its gilt coins, and Japanese _Foukousas_,\r
+with their green-toned golds and their marvellously plumaged birds.\r
+\r
+He had a special passion, also, for ecclesiastical vestments, as indeed\r
+he had for everything connected with the service of the Church. In the\r
+long cedar chests that lined the west gallery of his house, he had\r
+stored away many rare and beautiful specimens of what is really the\r
+raiment of the Bride of Christ, who must wear purple and jewels and\r
+fine linen that she may hide the pallid macerated body that is worn by\r
+the suffering that she seeks for and wounded by self-inflicted pain.\r
+He possessed a gorgeous cope of crimson silk and gold-thread damask,\r
+figured with a repeating pattern of golden pomegranates set in\r
+six-petalled formal blossoms, beyond which on either side was the\r
+pine-apple device wrought in seed-pearls. The orphreys were divided\r
+into panels representing scenes from the life of the Virgin, and the\r
+coronation of the Virgin was figured in coloured silks upon the hood.\r
+This was Italian work of the fifteenth century. Another cope was of\r
+green velvet, embroidered with heart-shaped groups of acanthus-leaves,\r
+from which spread long-stemmed white blossoms, the details of which\r
+were picked out with silver thread and coloured crystals. The morse\r
+bore a seraph's head in gold-thread raised work. The orphreys were\r
+woven in a diaper of red and gold silk, and were starred with\r
+medallions of many saints and martyrs, among whom was St. Sebastian.\r
+He had chasubles, also, of amber-coloured silk, and blue silk and gold\r
+brocade, and yellow silk damask and cloth of gold, figured with\r
+representations of the Passion and Crucifixion of Christ, and\r
+embroidered with lions and peacocks and other emblems; dalmatics of\r
+white satin and pink silk damask, decorated with tulips and dolphins\r
+and _fleurs-de-lis_; altar frontals of crimson velvet and blue linen; and\r
+many corporals, chalice-veils, and sudaria. In the mystic offices to\r
+which such things were put, there was something that quickened his\r
+imagination.\r
+\r
+For these treasures, and everything that he collected in his lovely\r
+house, were to be to him means of forgetfulness, modes by which he\r
+could escape, for a season, from the fear that seemed to him at times\r
+to be almost too great to be borne. Upon the walls of the lonely\r
+locked room where he had spent so much of his boyhood, he had hung with\r
+his own hands the terrible portrait whose changing features showed him\r
+the real degradation of his life, and in front of it had draped the\r
+purple-and-gold pall as a curtain. For weeks he would not go there,\r
+would forget the hideous painted thing, and get back his light heart,\r
+his wonderful joyousness, his passionate absorption in mere existence.\r
+Then, suddenly, some night he would creep out of the house, go down to\r
+dreadful places near Blue Gate Fields, and stay there, day after day,\r
+until he was driven away. On his return he would sit in front of the\r
+picture, sometimes loathing it and himself, but filled, at other\r
+times, with that pride of individualism that is half the\r
+fascination of sin, and smiling with secret pleasure at the misshapen\r
+shadow that had to bear the burden that should have been his own.\r
+\r
+After a few years he could not endure to be long out of England, and\r
+gave up the villa that he had shared at Trouville with Lord Henry, as\r
+well as the little white walled-in house at Algiers where they had more\r
+than once spent the winter. He hated to be separated from the picture\r
+that was such a part of his life, and was also afraid that during his\r
+absence some one might gain access to the room, in spite of the\r
+elaborate bars that he had caused to be placed upon the door.\r
+\r
+He was quite conscious that this would tell them nothing. It was true\r
+that the portrait still preserved, under all the foulness and ugliness\r
+of the face, its marked likeness to himself; but what could they learn\r
+from that? He would laugh at any one who tried to taunt him. He had\r
+not painted it. What was it to him how vile and full of shame it\r
+looked? Even if he told them, would they believe it?\r
+\r
+Yet he was afraid. Sometimes when he was down at his great house in\r
+Nottinghamshire, entertaining the fashionable young men of his own rank\r
+who were his chief companions, and astounding the county by the wanton\r
+luxury and gorgeous splendour of his mode of life, he would suddenly\r
+leave his guests and rush back to town to see that the door had not\r
+been tampered with and that the picture was still there. What if it\r
+should be stolen? The mere thought made him cold with horror. Surely\r
+the world would know his secret then. Perhaps the world already\r
+suspected it.\r
+\r
+For, while he fascinated many, there were not a few who distrusted him.\r
+He was very nearly blackballed at a West End club of which his birth\r
+and social position fully entitled him to become a member, and it was\r
+said that on one occasion, when he was brought by a friend into the\r
+smoking-room of the Churchill, the Duke of Berwick and another\r
+gentleman got up in a marked manner and went out. Curious stories\r
+became current about him after he had passed his twenty-fifth year. It\r
+was rumoured that he had been seen brawling with foreign sailors in a\r
+low den in the distant parts of Whitechapel, and that he consorted with\r
+thieves and coiners and knew the mysteries of their trade. His\r
+extraordinary absences became notorious, and, when he used to reappear\r
+again in society, men would whisper to each other in corners, or pass\r
+him with a sneer, or look at him with cold searching eyes, as though\r
+they were determined to discover his secret.\r
+\r
+Of such insolences and attempted slights he, of course, took no notice,\r
+and in the opinion of most people his frank debonair manner, his\r
+charming boyish smile, and the infinite grace of that wonderful youth\r
+that seemed never to leave him, were in themselves a sufficient answer\r
+to the calumnies, for so they termed them, that were circulated about\r
+him. It was remarked, however, that some of those who had been most\r
+intimate with him appeared, after a time, to shun him. Women who had\r
+wildly adored him, and for his sake had braved all social censure and\r
+set convention at defiance, were seen to grow pallid with shame or\r
+horror if Dorian Gray entered the room.\r
+\r
+Yet these whispered scandals only increased in the eyes of many his\r
+strange and dangerous charm. His great wealth was a certain element of\r
+security. Society--civilized society, at least--is never very ready to\r
+believe anything to the detriment of those who are both rich and\r
+fascinating. It feels instinctively that manners are of more\r
+importance than morals, and, in its opinion, the highest respectability\r
+is of much less value than the possession of a good _chef_. And, after\r
+all, it is a very poor consolation to be told that the man who has\r
+given one a bad dinner, or poor wine, is irreproachable in his private\r
+life. Even the cardinal virtues cannot atone for half-cold _entrees_, as\r
+Lord Henry remarked once, in a discussion on the subject, and there is\r
+possibly a good deal to be said for his view. For the canons of good\r
+society are, or should be, the same as the canons of art. Form is\r
+absolutely essential to it. It should have the dignity of a ceremony,\r
+as well as its unreality, and should combine the insincere character of\r
+a romantic play with the wit and beauty that make such plays delightful\r
+to us. Is insincerity such a terrible thing? I think not. It is\r
+merely a method by which we can multiply our personalities.\r
+\r
+Such, at any rate, was Dorian Gray's opinion. He used to wonder at the\r
+shallow psychology of those who conceive the ego in man as a thing\r
+simple, permanent, reliable, and of one essence. To him, man was a\r
+being with myriad lives and myriad sensations, a complex multiform\r
+creature that bore within itself strange legacies of thought and\r
+passion, and whose very flesh was tainted with the monstrous maladies\r
+of the dead. He loved to stroll through the gaunt cold picture-gallery\r
+of his country house and look at the various portraits of those whose\r
+blood flowed in his veins. Here was Philip Herbert, described by\r
+Francis Osborne, in his Memoires on the Reigns of Queen Elizabeth and\r
+King James, as one who was "caressed by the Court for his handsome\r
+face, which kept him not long company." Was it young Herbert's life\r
+that he sometimes led? Had some strange poisonous germ crept from body\r
+to body till it had reached his own? Was it some dim sense of that\r
+ruined grace that had made him so suddenly, and almost without cause,\r
+give utterance, in Basil Hallward's studio, to the mad prayer that had\r
+so changed his life? Here, in gold-embroidered red doublet, jewelled\r
+surcoat, and gilt-edged ruff and wristbands, stood Sir Anthony Sherard,\r
+with his silver-and-black armour piled at his feet. What had this\r
+man's legacy been? Had the lover of Giovanna of Naples bequeathed him\r
+some inheritance of sin and shame? Were his own actions merely the\r
+dreams that the dead man had not dared to realize? Here, from the\r
+fading canvas, smiled Lady Elizabeth Devereux, in her gauze hood, pearl\r
+stomacher, and pink slashed sleeves. A flower was in her right hand,\r
+and her left clasped an enamelled collar of white and damask roses. On\r
+a table by her side lay a mandolin and an apple. There were large\r
+green rosettes upon her little pointed shoes. He knew her life, and\r
+the strange stories that were told about her lovers. Had he something\r
+of her temperament in him? These oval, heavy-lidded eyes seemed to\r
+look curiously at him. What of George Willoughby, with his powdered\r
+hair and fantastic patches? How evil he looked! The face was\r
+saturnine and swarthy, and the sensual lips seemed to be twisted with\r
+disdain. Delicate lace ruffles fell over the lean yellow hands that\r
+were so overladen with rings. He had been a macaroni of the eighteenth\r
+century, and the friend, in his youth, of Lord Ferrars. What of the\r
+second Lord Beckenham, the companion of the Prince Regent in his\r
+wildest days, and one of the witnesses at the secret marriage with Mrs.\r
+Fitzherbert? How proud and handsome he was, with his chestnut curls\r
+and insolent pose! What passions had he bequeathed? The world had\r
+looked upon him as infamous. He had led the orgies at Carlton House.\r
+The star of the Garter glittered upon his breast. Beside him hung the\r
+portrait of his wife, a pallid, thin-lipped woman in black. Her blood,\r
+also, stirred within him. How curious it all seemed! And his mother\r
+with her Lady Hamilton face and her moist, wine-dashed lips--he knew\r
+what he had got from her. He had got from her his beauty, and his\r
+passion for the beauty of others. She laughed at him in her loose\r
+Bacchante dress. There were vine leaves in her hair. The purple\r
+spilled from the cup she was holding. The carnations of the painting\r
+had withered, but the eyes were still wonderful in their depth and\r
+brilliancy of colour. They seemed to follow him wherever he went.\r
+\r
+Yet one had ancestors in literature as well as in one's own race,\r
+nearer perhaps in type and temperament, many of them, and certainly\r
+with an influence of which one was more absolutely conscious. There\r
+were times when it appeared to Dorian Gray that the whole of history\r
+was merely the record of his own life, not as he had lived it in act\r
+and circumstance, but as his imagination had created it for him, as it\r
+had been in his brain and in his passions. He felt that he had known\r
+them all, those strange terrible figures that had passed across the\r
+stage of the world and made sin so marvellous and evil so full of\r
+subtlety. It seemed to him that in some mysterious way their lives had\r
+been his own.\r
+\r
+The hero of the wonderful novel that had so influenced his life had\r
+himself known this curious fancy. In the seventh chapter he tells how,\r
+crowned with laurel, lest lightning might strike him, he had sat, as\r
+Tiberius, in a garden at Capri, reading the shameful books of\r
+Elephantis, while dwarfs and peacocks strutted round him and the\r
+flute-player mocked the swinger of the censer; and, as Caligula, had\r
+caroused with the green-shirted jockeys in their stables and supped in\r
+an ivory manger with a jewel-frontleted horse; and, as Domitian, had\r
+wandered through a corridor lined with marble mirrors, looking round\r
+with haggard eyes for the reflection of the dagger that was to end his\r
+days, and sick with that ennui, that terrible _taedium vitae_, that comes\r
+on those to whom life denies nothing; and had peered through a clear\r
+emerald at the red shambles of the circus and then, in a litter of\r
+pearl and purple drawn by silver-shod mules, been carried through the\r
+Street of Pomegranates to a House of Gold and heard men cry on Nero\r
+Caesar as he passed by; and, as Elagabalus, had painted his face with\r
+colours, and plied the distaff among the women, and brought the Moon\r
+from Carthage and given her in mystic marriage to the Sun.\r
+\r
+Over and over again Dorian used to read this fantastic chapter, and the\r
+two chapters immediately following, in which, as in some curious\r
+tapestries or cunningly wrought enamels, were pictured the awful and\r
+beautiful forms of those whom vice and blood and weariness had made\r
+monstrous or mad: Filippo, Duke of Milan, who slew his wife and\r
+painted her lips with a scarlet poison that her lover might suck death\r
+from the dead thing he fondled; Pietro Barbi, the Venetian, known as\r
+Paul the Second, who sought in his vanity to assume the title of\r
+Formosus, and whose tiara, valued at two hundred thousand florins, was\r
+bought at the price of a terrible sin; Gian Maria Visconti, who used\r
+hounds to chase living men and whose murdered body was covered with\r
+roses by a harlot who had loved him; the Borgia on his white horse,\r
+with Fratricide riding beside him and his mantle stained with the blood\r
+of Perotto; Pietro Riario, the young Cardinal Archbishop of Florence,\r
+child and minion of Sixtus IV, whose beauty was equalled only by his\r
+debauchery, and who received Leonora of Aragon in a pavilion of white\r
+and crimson silk, filled with nymphs and centaurs, and gilded a boy\r
+that he might serve at the feast as Ganymede or Hylas; Ezzelin, whose\r
+melancholy could be cured only by the spectacle of death, and who had a\r
+passion for red blood, as other men have for red wine--the son of the\r
+Fiend, as was reported, and one who had cheated his father at dice when\r
+gambling with him for his own soul; Giambattista Cibo, who in mockery\r
+took the name of Innocent and into whose torpid veins the blood of\r
+three lads was infused by a Jewish doctor; Sigismondo Malatesta, the\r
+lover of Isotta and the lord of Rimini, whose effigy was burned at Rome\r
+as the enemy of God and man, who strangled Polyssena with a napkin, and\r
+gave poison to Ginevra d'Este in a cup of emerald, and in honour of a\r
+shameful passion built a pagan church for Christian worship; Charles\r
+VI, who had so wildly adored his brother's wife that a leper had warned\r
+him of the insanity that was coming on him, and who, when his brain had\r
+sickened and grown strange, could only be soothed by Saracen cards\r
+painted with the images of love and death and madness; and, in his\r
+trimmed jerkin and jewelled cap and acanthuslike curls, Grifonetto\r
+Baglioni, who slew Astorre with his bride, and Simonetto with his page,\r
+and whose comeliness was such that, as he lay dying in the yellow\r
+piazza of Perugia, those who had hated him could not choose but weep,\r
+and Atalanta, who had cursed him, blessed him.\r
+\r
+There was a horrible fascination in them all. He saw them at night,\r
+and they troubled his imagination in the day. The Renaissance knew of\r
+strange manners of poisoning--poisoning by a helmet and a lighted\r
+torch, by an embroidered glove and a jewelled fan, by a gilded pomander\r
+and by an amber chain. Dorian Gray had been poisoned by a book. There\r
+were moments when he looked on evil simply as a mode through which he\r
+could realize his conception of the beautiful.\r
+\r
+\r
+\r
+CHAPTER 12\r
+\r
+It was on the ninth of November, the eve of his own thirty-eighth\r
+birthday, as he often remembered afterwards.\r
+\r
+He was walking home about eleven o'clock from Lord Henry's, where he\r
+had been dining, and was wrapped in heavy furs, as the night was cold\r
+and foggy. At the corner of Grosvenor Square and South Audley Street,\r
+a man passed him in the mist, walking very fast and with the collar of\r
+his grey ulster turned up. He had a bag in his hand. Dorian\r
+recognized him. It was Basil Hallward. A strange sense of fear, for\r
+which he could not account, came over him. He made no sign of\r
+recognition and went on quickly in the direction of his own house.\r
+\r
+But Hallward had seen him. Dorian heard him first stopping on the\r
+pavement and then hurrying after him. In a few moments, his hand was\r
+on his arm.\r
+\r
+"Dorian! What an extraordinary piece of luck! I have been waiting for\r
+you in your library ever since nine o'clock. Finally I took pity on\r
+your tired servant and told him to go to bed, as he let me out. I am\r
+off to Paris by the midnight train, and I particularly wanted to see\r
+you before I left. I thought it was you, or rather your fur coat, as\r
+you passed me. But I wasn't quite sure. Didn't you recognize me?"\r
+\r
+"In this fog, my dear Basil? Why, I can't even recognize Grosvenor\r
+Square. I believe my house is somewhere about here, but I don't feel\r
+at all certain about it. I am sorry you are going away, as I have not\r
+seen you for ages. But I suppose you will be back soon?"\r
+\r
+"No: I am going to be out of England for six months. I intend to take\r
+a studio in Paris and shut myself up till I have finished a great\r
+picture I have in my head. However, it wasn't about myself I wanted to\r
+talk. Here we are at your door. Let me come in for a moment. I have\r
+something to say to you."\r
+\r
+"I shall be charmed. But won't you miss your train?" said Dorian Gray\r
+languidly as he passed up the steps and opened the door with his\r
+latch-key.\r
+\r
+The lamplight struggled out through the fog, and Hallward looked at his\r
+watch. "I have heaps of time," he answered. "The train doesn't go\r
+till twelve-fifteen, and it is only just eleven. In fact, I was on my\r
+way to the club to look for you, when I met you. You see, I shan't\r
+have any delay about luggage, as I have sent on my heavy things. All I\r
+have with me is in this bag, and I can easily get to Victoria in twenty\r
+minutes."\r
+\r
+Dorian looked at him and smiled. "What a way for a fashionable painter\r
+to travel! A Gladstone bag and an ulster! Come in, or the fog will\r
+get into the house. And mind you don't talk about anything serious.\r
+Nothing is serious nowadays. At least nothing should be."\r
+\r
+Hallward shook his head, as he entered, and followed Dorian into the\r
+library. There was a bright wood fire blazing in the large open\r
+hearth. The lamps were lit, and an open Dutch silver spirit-case\r
+stood, with some siphons of soda-water and large cut-glass tumblers, on\r
+a little marqueterie table.\r
+\r
+"You see your servant made me quite at home, Dorian. He gave me\r
+everything I wanted, including your best gold-tipped cigarettes. He is\r
+a most hospitable creature. I like him much better than the Frenchman\r
+you used to have. What has become of the Frenchman, by the bye?"\r
+\r
+Dorian shrugged his shoulders. "I believe he married Lady Radley's\r
+maid, and has established her in Paris as an English dressmaker.\r
+Anglomania is very fashionable over there now, I hear. It seems silly\r
+of the French, doesn't it? But--do you know?--he was not at all a bad\r
+servant. I never liked him, but I had nothing to complain about. One\r
+often imagines things that are quite absurd. He was really very\r
+devoted to me and seemed quite sorry when he went away. Have another\r
+brandy-and-soda? Or would you like hock-and-seltzer? I always take\r
+hock-and-seltzer myself. There is sure to be some in the next room."\r
+\r
+"Thanks, I won't have anything more," said the painter, taking his cap\r
+and coat off and throwing them on the bag that he had placed in the\r
+corner. "And now, my dear fellow, I want to speak to you seriously.\r
+Don't frown like that. You make it so much more difficult for me."\r
+\r
+"What is it all about?" cried Dorian in his petulant way, flinging\r
+himself down on the sofa. "I hope it is not about myself. I am tired\r
+of myself to-night. I should like to be somebody else."\r
+\r
+"It is about yourself," answered Hallward in his grave deep voice, "and\r
+I must say it to you. I shall only keep you half an hour."\r
+\r
+Dorian sighed and lit a cigarette. "Half an hour!" he murmured.\r
+\r
+"It is not much to ask of you, Dorian, and it is entirely for your own\r
+sake that I am speaking. I think it right that you should know that\r
+the most dreadful things are being said against you in London."\r
+\r
+"I don't wish to know anything about them. I love scandals about other\r
+people, but scandals about myself don't interest me. They have not got\r
+the charm of novelty."\r
+\r
+"They must interest you, Dorian. Every gentleman is interested in his\r
+good name. You don't want people to talk of you as something vile and\r
+degraded. Of course, you have your position, and your wealth, and all\r
+that kind of thing. But position and wealth are not everything. Mind\r
+you, I don't believe these rumours at all. At least, I can't believe\r
+them when I see you. Sin is a thing that writes itself across a man's\r
+face. It cannot be concealed. People talk sometimes of secret vices.\r
+There are no such things. If a wretched man has a vice, it shows\r
+itself in the lines of his mouth, the droop of his eyelids, the\r
+moulding of his hands even. Somebody--I won't mention his name, but\r
+you know him--came to me last year to have his portrait done. I had\r
+never seen him before, and had never heard anything about him at the\r
+time, though I have heard a good deal since. He offered an extravagant\r
+price. I refused him. There was something in the shape of his fingers\r
+that I hated. I know now that I was quite right in what I fancied\r
+about him. His life is dreadful. But you, Dorian, with your pure,\r
+bright, innocent face, and your marvellous untroubled youth--I can't\r
+believe anything against you. And yet I see you very seldom, and you\r
+never come down to the studio now, and when I am away from you, and I\r
+hear all these hideous things that people are whispering about you, I\r
+don't know what to say. Why is it, Dorian, that a man like the Duke of\r
+Berwick leaves the room of a club when you enter it? Why is it that so\r
+many gentlemen in London will neither go to your house or invite you to\r
+theirs? You used to be a friend of Lord Staveley. I met him at dinner\r
+last week. Your name happened to come up in conversation, in\r
+connection with the miniatures you have lent to the exhibition at the\r
+Dudley. Staveley curled his lip and said that you might have the most\r
+artistic tastes, but that you were a man whom no pure-minded girl\r
+should be allowed to know, and whom no chaste woman should sit in the\r
+same room with. I reminded him that I was a friend of yours, and asked\r
+him what he meant. He told me. He told me right out before everybody.\r
+It was horrible! Why is your friendship so fatal to young men? There\r
+was that wretched boy in the Guards who committed suicide. You were\r
+his great friend. There was Sir Henry Ashton, who had to leave England\r
+with a tarnished name. You and he were inseparable. What about Adrian\r
+Singleton and his dreadful end? What about Lord Kent's only son and\r
+his career? I met his father yesterday in St. James's Street. He\r
+seemed broken with shame and sorrow. What about the young Duke of\r
+Perth? What sort of life has he got now? What gentleman would\r
+associate with him?"\r
+\r
+"Stop, Basil. You are talking about things of which you know nothing,"\r
+said Dorian Gray, biting his lip, and with a note of infinite contempt\r
+in his voice. "You ask me why Berwick leaves a room when I enter it.\r
+It is because I know everything about his life, not because he knows\r
+anything about mine. With such blood as he has in his veins, how could\r
+his record be clean? You ask me about Henry Ashton and young Perth.\r
+Did I teach the one his vices, and the other his debauchery? If Kent's\r
+silly son takes his wife from the streets, what is that to me? If\r
+Adrian Singleton writes his friend's name across a bill, am I his\r
+keeper? I know how people chatter in England. The middle classes air\r
+their moral prejudices over their gross dinner-tables, and whisper\r
+about what they call the profligacies of their betters in order to try\r
+and pretend that they are in smart society and on intimate terms with\r
+the people they slander. In this country, it is enough for a man to\r
+have distinction and brains for every common tongue to wag against him.\r
+And what sort of lives do these people, who pose as being moral, lead\r
+themselves? My dear fellow, you forget that we are in the native land\r
+of the hypocrite."\r
+\r
+"Dorian," cried Hallward, "that is not the question. England is bad\r
+enough I know, and English society is all wrong. That is the reason\r
+why I want you to be fine. You have not been fine. One has a right to\r
+judge of a man by the effect he has over his friends. Yours seem to\r
+lose all sense of honour, of goodness, of purity. You have filled them\r
+with a madness for pleasure. They have gone down into the depths. You\r
+led them there. Yes: you led them there, and yet you can smile, as\r
+you are smiling now. And there is worse behind. I know you and Harry\r
+are inseparable. Surely for that reason, if for none other, you should\r
+not have made his sister's name a by-word."\r
+\r
+"Take care, Basil. You go too far."\r
+\r
+"I must speak, and you must listen. You shall listen. When you met\r
+Lady Gwendolen, not a breath of scandal had ever touched her. Is there\r
+a single decent woman in London now who would drive with her in the\r
+park? Why, even her children are not allowed to live with her. Then\r
+there are other stories--stories that you have been seen creeping at\r
+dawn out of dreadful houses and slinking in disguise into the foulest\r
+dens in London. Are they true? Can they be true? When I first heard\r
+them, I laughed. I hear them now, and they make me shudder. What\r
+about your country-house and the life that is led there? Dorian, you\r
+don't know what is said about you. I won't tell you that I don't want\r
+to preach to you. I remember Harry saying once that every man who\r
+turned himself into an amateur curate for the moment always began by\r
+saying that, and then proceeded to break his word. I do want to preach\r
+to you. I want you to lead such a life as will make the world respect\r
+you. I want you to have a clean name and a fair record. I want you to\r
+get rid of the dreadful people you associate with. Don't shrug your\r
+shoulders like that. Don't be so indifferent. You have a wonderful\r
+influence. Let it be for good, not for evil. They say that you\r
+corrupt every one with whom you become intimate, and that it is quite\r
+sufficient for you to enter a house for shame of some kind to follow\r
+after. I don't know whether it is so or not. How should I know? But\r
+it is said of you. I am told things that it seems impossible to doubt.\r
+Lord Gloucester was one of my greatest friends at Oxford. He showed me\r
+a letter that his wife had written to him when she was dying alone in\r
+her villa at Mentone. Your name was implicated in the most terrible\r
+confession I ever read. I told him that it was absurd--that I knew you\r
+thoroughly and that you were incapable of anything of the kind. Know\r
+you? I wonder do I know you? Before I could answer that, I should\r
+have to see your soul."\r
+\r
+"To see my soul!" muttered Dorian Gray, starting up from the sofa and\r
+turning almost white from fear.\r
+\r
+"Yes," answered Hallward gravely, and with deep-toned sorrow in his\r
+voice, "to see your soul. But only God can do that."\r
+\r
+A bitter laugh of mockery broke from the lips of the younger man. "You\r
+shall see it yourself, to-night!" he cried, seizing a lamp from the\r
+table. "Come: it is your own handiwork. Why shouldn't you look at\r
+it? You can tell the world all about it afterwards, if you choose.\r
+Nobody would believe you. If they did believe you, they would like me\r
+all the better for it. I know the age better than you do, though you\r
+will prate about it so tediously. Come, I tell you. You have\r
+chattered enough about corruption. Now you shall look on it face to\r
+face."\r
+\r
+There was the madness of pride in every word he uttered. He stamped\r
+his foot upon the ground in his boyish insolent manner. He felt a\r
+terrible joy at the thought that some one else was to share his secret,\r
+and that the man who had painted the portrait that was the origin of\r
+all his shame was to be burdened for the rest of his life with the\r
+hideous memory of what he had done.\r
+\r
+"Yes," he continued, coming closer to him and looking steadfastly into\r
+his stern eyes, "I shall show you my soul. You shall see the thing\r
+that you fancy only God can see."\r
+\r
+Hallward started back. "This is blasphemy, Dorian!" he cried. "You\r
+must not say things like that. They are horrible, and they don't mean\r
+anything."\r
+\r
+"You think so?" He laughed again.\r
+\r
+"I know so. As for what I said to you to-night, I said it for your\r
+good. You know I have been always a stanch friend to you."\r
+\r
+"Don't touch me. Finish what you have to say."\r
+\r
+A twisted flash of pain shot across the painter's face. He paused for\r
+a moment, and a wild feeling of pity came over him. After all, what\r
+right had he to pry into the life of Dorian Gray? If he had done a\r
+tithe of what was rumoured about him, how much he must have suffered!\r
+Then he straightened himself up, and walked over to the fire-place, and\r
+stood there, looking at the burning logs with their frostlike ashes and\r
+their throbbing cores of flame.\r
+\r
+"I am waiting, Basil," said the young man in a hard clear voice.\r
+\r
+He turned round. "What I have to say is this," he cried. "You must\r
+give me some answer to these horrible charges that are made against\r
+you. If you tell me that they are absolutely untrue from beginning to\r
+end, I shall believe you. Deny them, Dorian, deny them! Can't you see\r
+what I am going through? My God! don't tell me that you are bad, and\r
+corrupt, and shameful."\r
+\r
+Dorian Gray smiled. There was a curl of contempt in his lips. "Come\r
+upstairs, Basil," he said quietly. "I keep a diary of my life from day\r
+to day, and it never leaves the room in which it is written. I shall\r
+show it to you if you come with me."\r
+\r
+"I shall come with you, Dorian, if you wish it. I see I have missed my\r
+train. That makes no matter. I can go to-morrow. But don't ask me to\r
+read anything to-night. All I want is a plain answer to my question."\r
+\r
+"That shall be given to you upstairs. I could not give it here. You\r
+will not have to read long."\r
+\r
+\r
+\r
+CHAPTER 13\r
+\r
+He passed out of the room and began the ascent, Basil Hallward\r
+following close behind. They walked softly, as men do instinctively at\r
+night. The lamp cast fantastic shadows on the wall and staircase. A\r
+rising wind made some of the windows rattle.\r
+\r
+When they reached the top landing, Dorian set the lamp down on the\r
+floor, and taking out the key, turned it in the lock. "You insist on\r
+knowing, Basil?" he asked in a low voice.\r
+\r
+"Yes."\r
+\r
+"I am delighted," he answered, smiling. Then he added, somewhat\r
+harshly, "You are the one man in the world who is entitled to know\r
+everything about me. You have had more to do with my life than you\r
+think"; and, taking up the lamp, he opened the door and went in. A\r
+cold current of air passed them, and the light shot up for a moment in\r
+a flame of murky orange. He shuddered. "Shut the door behind you," he\r
+whispered, as he placed the lamp on the table.\r
+\r
+Hallward glanced round him with a puzzled expression. The room looked\r
+as if it had not been lived in for years. A faded Flemish tapestry, a\r
+curtained picture, an old Italian _cassone_, and an almost empty\r
+book-case--that was all that it seemed to contain, besides a chair and\r
+a table. As Dorian Gray was lighting a half-burned candle that was\r
+standing on the mantelshelf, he saw that the whole place was covered\r
+with dust and that the carpet was in holes. A mouse ran scuffling\r
+behind the wainscoting. There was a damp odour of mildew.\r
+\r
+"So you think that it is only God who sees the soul, Basil? Draw that\r
+curtain back, and you will see mine."\r
+\r
+The voice that spoke was cold and cruel. "You are mad, Dorian, or\r
+playing a part," muttered Hallward, frowning.\r
+\r
+"You won't? Then I must do it myself," said the young man, and he tore\r
+the curtain from its rod and flung it on the ground.\r
+\r
+An exclamation of horror broke from the painter's lips as he saw in the\r
+dim light the hideous face on the canvas grinning at him. There was\r
+something in its expression that filled him with disgust and loathing.\r
+Good heavens! it was Dorian Gray's own face that he was looking at!\r
+The horror, whatever it was, had not yet entirely spoiled that\r
+marvellous beauty. There was still some gold in the thinning hair and\r
+some scarlet on the sensual mouth. The sodden eyes had kept something\r
+of the loveliness of their blue, the noble curves had not yet\r
+completely passed away from chiselled nostrils and from plastic throat.\r
+Yes, it was Dorian himself. But who had done it? He seemed to\r
+recognize his own brushwork, and the frame was his own design. The\r
+idea was monstrous, yet he felt afraid. He seized the lighted candle,\r
+and held it to the picture. In the left-hand corner was his own name,\r
+traced in long letters of bright vermilion.\r
+\r
+It was some foul parody, some infamous ignoble satire. He had never\r
+done that. Still, it was his own picture. He knew it, and he felt as\r
+if his blood had changed in a moment from fire to sluggish ice. His\r
+own picture! What did it mean? Why had it altered? He turned and\r
+looked at Dorian Gray with the eyes of a sick man. His mouth twitched,\r
+and his parched tongue seemed unable to articulate. He passed his hand\r
+across his forehead. It was dank with clammy sweat.\r
+\r
+The young man was leaning against the mantelshelf, watching him with\r
+that strange expression that one sees on the faces of those who are\r
+absorbed in a play when some great artist is acting. There was neither\r
+real sorrow in it nor real joy. There was simply the passion of the\r
+spectator, with perhaps a flicker of triumph in his eyes. He had taken\r
+the flower out of his coat, and was smelling it, or pretending to do so.\r
+\r
+"What does this mean?" cried Hallward, at last. His own voice sounded\r
+shrill and curious in his ears.\r
+\r
+"Years ago, when I was a boy," said Dorian Gray, crushing the flower in\r
+his hand, "you met me, flattered me, and taught me to be vain of my\r
+good looks. One day you introduced me to a friend of yours, who\r
+explained to me the wonder of youth, and you finished a portrait of me\r
+that revealed to me the wonder of beauty. In a mad moment that, even\r
+now, I don't know whether I regret or not, I made a wish, perhaps you\r
+would call it a prayer...."\r
+\r
+"I remember it! Oh, how well I remember it! No! the thing is\r
+impossible. The room is damp. Mildew has got into the canvas. The\r
+paints I used had some wretched mineral poison in them. I tell you the\r
+thing is impossible."\r
+\r
+"Ah, what is impossible?" murmured the young man, going over to the\r
+window and leaning his forehead against the cold, mist-stained glass.\r
+\r
+"You told me you had destroyed it."\r
+\r
+"I was wrong. It has destroyed me."\r
+\r
+"I don't believe it is my picture."\r
+\r
+"Can't you see your ideal in it?" said Dorian bitterly.\r
+\r
+"My ideal, as you call it..."\r
+\r
+"As you called it."\r
+\r
+"There was nothing evil in it, nothing shameful. You were to me such\r
+an ideal as I shall never meet again. This is the face of a satyr."\r
+\r
+"It is the face of my soul."\r
+\r
+"Christ! what a thing I must have worshipped! It has the eyes of a\r
+devil."\r
+\r
+"Each of us has heaven and hell in him, Basil," cried Dorian with a\r
+wild gesture of despair.\r
+\r
+Hallward turned again to the portrait and gazed at it. "My God! If it\r
+is true," he exclaimed, "and this is what you have done with your life,\r
+why, you must be worse even than those who talk against you fancy you\r
+to be!" He held the light up again to the canvas and examined it. The\r
+surface seemed to be quite undisturbed and as he had left it. It was\r
+from within, apparently, that the foulness and horror had come.\r
+Through some strange quickening of inner life the leprosies of sin were\r
+slowly eating the thing away. The rotting of a corpse in a watery\r
+grave was not so fearful.\r
+\r
+His hand shook, and the candle fell from its socket on the floor and\r
+lay there sputtering. He placed his foot on it and put it out. Then\r
+he flung himself into the rickety chair that was standing by the table\r
+and buried his face in his hands.\r
+\r
+"Good God, Dorian, what a lesson! What an awful lesson!" There was no\r
+answer, but he could hear the young man sobbing at the window. "Pray,\r
+Dorian, pray," he murmured. "What is it that one was taught to say in\r
+one's boyhood? 'Lead us not into temptation. Forgive us our sins.\r
+Wash away our iniquities.' Let us say that together. The prayer of\r
+your pride has been answered. The prayer of your repentance will be\r
+answered also. I worshipped you too much. I am punished for it. You\r
+worshipped yourself too much. We are both punished."\r
+\r
+Dorian Gray turned slowly around and looked at him with tear-dimmed\r
+eyes. "It is too late, Basil," he faltered.\r
+\r
+"It is never too late, Dorian. Let us kneel down and try if we cannot\r
+remember a prayer. Isn't there a verse somewhere, 'Though your sins be\r
+as scarlet, yet I will make them as white as snow'?"\r
+\r
+"Those words mean nothing to me now."\r
+\r
+"Hush! Don't say that. You have done enough evil in your life. My\r
+God! Don't you see that accursed thing leering at us?"\r
+\r
+Dorian Gray glanced at the picture, and suddenly an uncontrollable\r
+feeling of hatred for Basil Hallward came over him, as though it had\r
+been suggested to him by the image on the canvas, whispered into his\r
+ear by those grinning lips. The mad passions of a hunted animal\r
+stirred within him, and he loathed the man who was seated at the table,\r
+more than in his whole life he had ever loathed anything. He glanced\r
+wildly around. Something glimmered on the top of the painted chest\r
+that faced him. His eye fell on it. He knew what it was. It was a\r
+knife that he had brought up, some days before, to cut a piece of cord,\r
+and had forgotten to take away with him. He moved slowly towards it,\r
+passing Hallward as he did so. As soon as he got behind him, he seized\r
+it and turned round. Hallward stirred in his chair as if he was going\r
+to rise. He rushed at him and dug the knife into the great vein that\r
+is behind the ear, crushing the man's head down on the table and\r
+stabbing again and again.\r
+\r
+There was a stifled groan and the horrible sound of some one choking\r
+with blood. Three times the outstretched arms shot up convulsively,\r
+waving grotesque, stiff-fingered hands in the air. He stabbed him\r
+twice more, but the man did not move. Something began to trickle on\r
+the floor. He waited for a moment, still pressing the head down. Then\r
+he threw the knife on the table, and listened.\r
+\r
+He could hear nothing, but the drip, drip on the threadbare carpet. He\r
+opened the door and went out on the landing. The house was absolutely\r
+quiet. No one was about. For a few seconds he stood bending over the\r
+balustrade and peering down into the black seething well of darkness.\r
+Then he took out the key and returned to the room, locking himself in\r
+as he did so.\r
+\r
+The thing was still seated in the chair, straining over the table with\r
+bowed head, and humped back, and long fantastic arms. Had it not been\r
+for the red jagged tear in the neck and the clotted black pool that was\r
+slowly widening on the table, one would have said that the man was\r
+simply asleep.\r
+\r
+How quickly it had all been done! He felt strangely calm, and walking\r
+over to the window, opened it and stepped out on the balcony. The wind\r
+had blown the fog away, and the sky was like a monstrous peacock's\r
+tail, starred with myriads of golden eyes. He looked down and saw the\r
+policeman going his rounds and flashing the long beam of his lantern on\r
+the doors of the silent houses. The crimson spot of a prowling hansom\r
+gleamed at the corner and then vanished. A woman in a fluttering shawl\r
+was creeping slowly by the railings, staggering as she went. Now and\r
+then she stopped and peered back. Once, she began to sing in a hoarse\r
+voice. The policeman strolled over and said something to her. She\r
+stumbled away, laughing. A bitter blast swept across the square. The\r
+gas-lamps flickered and became blue, and the leafless trees shook their\r
+black iron branches to and fro. He shivered and went back, closing the\r
+window behind him.\r
+\r
+Having reached the door, he turned the key and opened it. He did not\r
+even glance at the murdered man. He felt that the secret of the whole\r
+thing was not to realize the situation. The friend who had painted the\r
+fatal portrait to which all his misery had been due had gone out of his\r
+life. That was enough.\r
+\r
+Then he remembered the lamp. It was a rather curious one of Moorish\r
+workmanship, made of dull silver inlaid with arabesques of burnished\r
+steel, and studded with coarse turquoises. Perhaps it might be missed\r
+by his servant, and questions would be asked. He hesitated for a\r
+moment, then he turned back and took it from the table. He could not\r
+help seeing the dead thing. How still it was! How horribly white the\r
+long hands looked! It was like a dreadful wax image.\r
+\r
+Having locked the door behind him, he crept quietly downstairs. The\r
+woodwork creaked and seemed to cry out as if in pain. He stopped\r
+several times and waited. No: everything was still. It was merely\r
+the sound of his own footsteps.\r
+\r
+When he reached the library, he saw the bag and coat in the corner.\r
+They must be hidden away somewhere. He unlocked a secret press that\r
+was in the wainscoting, a press in which he kept his own curious\r
+disguises, and put them into it. He could easily burn them afterwards.\r
+Then he pulled out his watch. It was twenty minutes to two.\r
+\r
+He sat down and began to think. Every year--every month, almost--men\r
+were strangled in England for what he had done. There had been a\r
+madness of murder in the air. Some red star had come too close to the\r
+earth.... And yet, what evidence was there against him? Basil Hallward\r
+had left the house at eleven. No one had seen him come in again. Most\r
+of the servants were at Selby Royal. His valet had gone to bed....\r
+Paris! Yes. It was to Paris that Basil had gone, and by the midnight\r
+train, as he had intended. With his curious reserved habits, it would\r
+be months before any suspicions would be roused. Months! Everything\r
+could be destroyed long before then.\r
+\r
+A sudden thought struck him. He put on his fur coat and hat and went\r
+out into the hall. There he paused, hearing the slow heavy tread of\r
+the policeman on the pavement outside and seeing the flash of the\r
+bull's-eye reflected in the window. He waited and held his breath.\r
+\r
+After a few moments he drew back the latch and slipped out, shutting\r
+the door very gently behind him. Then he began ringing the bell. In\r
+about five minutes his valet appeared, half-dressed and looking very\r
+drowsy.\r
+\r
+"I am sorry to have had to wake you up, Francis," he said, stepping in;\r
+"but I had forgotten my latch-key. What time is it?"\r
+\r
+"Ten minutes past two, sir," answered the man, looking at the clock and\r
+blinking.\r
+\r
+"Ten minutes past two? How horribly late! You must wake me at nine\r
+to-morrow. I have some work to do."\r
+\r
+"All right, sir."\r
+\r
+"Did any one call this evening?"\r
+\r
+"Mr. Hallward, sir. He stayed here till eleven, and then he went away\r
+to catch his train."\r
+\r
+"Oh! I am sorry I didn't see him. Did he leave any message?"\r
+\r
+"No, sir, except that he would write to you from Paris, if he did not\r
+find you at the club."\r
+\r
+"That will do, Francis. Don't forget to call me at nine to-morrow."\r
+\r
+"No, sir."\r
+\r
+The man shambled down the passage in his slippers.\r
+\r
+Dorian Gray threw his hat and coat upon the table and passed into the\r
+library. For a quarter of an hour he walked up and down the room,\r
+biting his lip and thinking. Then he took down the Blue Book from one\r
+of the shelves and began to turn over the leaves. "Alan Campbell, 152,\r
+Hertford Street, Mayfair." Yes; that was the man he wanted.\r
+\r
+\r
+\r
+CHAPTER 14\r
+\r
+At nine o'clock the next morning his servant came in with a cup of\r
+chocolate on a tray and opened the shutters. Dorian was sleeping quite\r
+peacefully, lying on his right side, with one hand underneath his\r
+cheek. He looked like a boy who had been tired out with play, or study.\r
+\r
+The man had to touch him twice on the shoulder before he woke, and as\r
+he opened his eyes a faint smile passed across his lips, as though he\r
+had been lost in some delightful dream. Yet he had not dreamed at all.\r
+His night had been untroubled by any images of pleasure or of pain.\r
+But youth smiles without any reason. It is one of its chiefest charms.\r
+\r
+He turned round, and leaning upon his elbow, began to sip his\r
+chocolate. The mellow November sun came streaming into the room. The\r
+sky was bright, and there was a genial warmth in the air. It was\r
+almost like a morning in May.\r
+\r
+Gradually the events of the preceding night crept with silent,\r
+blood-stained feet into his brain and reconstructed themselves there\r
+with terrible distinctness. He winced at the memory of all that he had\r
+suffered, and for a moment the same curious feeling of loathing for\r
+Basil Hallward that had made him kill him as he sat in the chair came\r
+back to him, and he grew cold with passion. The dead man was still\r
+sitting there, too, and in the sunlight now. How horrible that was!\r
+Such hideous things were for the darkness, not for the day.\r
+\r
+He felt that if he brooded on what he had gone through he would sicken\r
+or grow mad. There were sins whose fascination was more in the memory\r
+than in the doing of them, strange triumphs that gratified the pride\r
+more than the passions, and gave to the intellect a quickened sense of\r
+joy, greater than any joy they brought, or could ever bring, to the\r
+senses. But this was not one of them. It was a thing to be driven out\r
+of the mind, to be drugged with poppies, to be strangled lest it might\r
+strangle one itself.\r
+\r
+When the half-hour struck, he passed his hand across his forehead, and\r
+then got up hastily and dressed himself with even more than his usual\r
+care, giving a good deal of attention to the choice of his necktie and\r
+scarf-pin and changing his rings more than once. He spent a long time\r
+also over breakfast, tasting the various dishes, talking to his valet\r
+about some new liveries that he was thinking of getting made for the\r
+servants at Selby, and going through his correspondence. At some of\r
+the letters, he smiled. Three of them bored him. One he read several\r
+times over and then tore up with a slight look of annoyance in his\r
+face. "That awful thing, a woman's memory!" as Lord Henry had once\r
+said.\r
+\r
+After he had drunk his cup of black coffee, he wiped his lips slowly\r
+with a napkin, motioned to his servant to wait, and going over to the\r
+table, sat down and wrote two letters. One he put in his pocket, the\r
+other he handed to the valet.\r
+\r
+"Take this round to 152, Hertford Street, Francis, and if Mr. Campbell\r
+is out of town, get his address."\r
+\r
+As soon as he was alone, he lit a cigarette and began sketching upon a\r
+piece of paper, drawing first flowers and bits of architecture, and\r
+then human faces. Suddenly he remarked that every face that he drew\r
+seemed to have a fantastic likeness to Basil Hallward. He frowned, and\r
+getting up, went over to the book-case and took out a volume at hazard.\r
+He was determined that he would not think about what had happened until\r
+it became absolutely necessary that he should do so.\r
+\r
+When he had stretched himself on the sofa, he looked at the title-page\r
+of the book. It was Gautier's Emaux et Camees, Charpentier's\r
+Japanese-paper edition, with the Jacquemart etching. The binding was\r
+of citron-green leather, with a design of gilt trellis-work and dotted\r
+pomegranates. It had been given to him by Adrian Singleton. As he\r
+turned over the pages, his eye fell on the poem about the hand of\r
+Lacenaire, the cold yellow hand "_du supplice encore mal lavee_," with\r
+its downy red hairs and its "_doigts de faune_." He glanced at his own\r
+white taper fingers, shuddering slightly in spite of himself, and\r
+passed on, till he came to those lovely stanzas upon Venice:\r
+\r
+ Sur une gamme chromatique,\r
+ Le sein de perles ruisselant,\r
+ La Venus de l'Adriatique\r
+ Sort de l'eau son corps rose et blanc.\r
+\r
+ Les domes, sur l'azur des ondes\r
+ Suivant la phrase au pur contour,\r
+ S'enflent comme des gorges rondes\r
+ Que souleve un soupir d'amour.\r
+\r
+ L'esquif aborde et me depose,\r
+ Jetant son amarre au pilier,\r
+ Devant une facade rose,\r
+ Sur le marbre d'un escalier.\r
+\r
+\r
+How exquisite they were! As one read them, one seemed to be floating\r
+down the green water-ways of the pink and pearl city, seated in a black\r
+gondola with silver prow and trailing curtains. The mere lines looked\r
+to him like those straight lines of turquoise-blue that follow one as\r
+one pushes out to the Lido. The sudden flashes of colour reminded him\r
+of the gleam of the opal-and-iris-throated birds that flutter round the\r
+tall honeycombed Campanile, or stalk, with such stately grace, through\r
+the dim, dust-stained arcades. Leaning back with half-closed eyes, he\r
+kept saying over and over to himself:\r
+\r
+ "Devant une facade rose,\r
+ Sur le marbre d'un escalier."\r
+\r
+The whole of Venice was in those two lines. He remembered the autumn\r
+that he had passed there, and a wonderful love that had stirred him to\r
+mad delightful follies. There was romance in every place. But Venice,\r
+like Oxford, had kept the background for romance, and, to the true\r
+romantic, background was everything, or almost everything. Basil had\r
+been with him part of the time, and had gone wild over Tintoret. Poor\r
+Basil! What a horrible way for a man to die!\r
+\r
+He sighed, and took up the volume again, and tried to forget. He read\r
+of the swallows that fly in and out of the little _cafe_ at Smyrna where\r
+the Hadjis sit counting their amber beads and the turbaned merchants\r
+smoke their long tasselled pipes and talk gravely to each other; he\r
+read of the Obelisk in the Place de la Concorde that weeps tears of\r
+granite in its lonely sunless exile and longs to be back by the hot,\r
+lotus-covered Nile, where there are Sphinxes, and rose-red ibises, and\r
+white vultures with gilded claws, and crocodiles with small beryl eyes\r
+that crawl over the green steaming mud; he began to brood over those\r
+verses which, drawing music from kiss-stained marble, tell of that\r
+curious statue that Gautier compares to a contralto voice, the "_monstre\r
+charmant_" that couches in the porphyry-room of the Louvre. But after a\r
+time the book fell from his hand. He grew nervous, and a horrible fit\r
+of terror came over him. What if Alan Campbell should be out of\r
+England? Days would elapse before he could come back. Perhaps he\r
+might refuse to come. What could he do then? Every moment was of\r
+vital importance.\r
+\r
+They had been great friends once, five years before--almost\r
+inseparable, indeed. Then the intimacy had come suddenly to an end.\r
+When they met in society now, it was only Dorian Gray who smiled: Alan\r
+Campbell never did.\r
+\r
+He was an extremely clever young man, though he had no real\r
+appreciation of the visible arts, and whatever little sense of the\r
+beauty of poetry he possessed he had gained entirely from Dorian. His\r
+dominant intellectual passion was for science. At Cambridge he had\r
+spent a great deal of his time working in the laboratory, and had taken\r
+a good class in the Natural Science Tripos of his year. Indeed, he was\r
+still devoted to the study of chemistry, and had a laboratory of his\r
+own in which he used to shut himself up all day long, greatly to the\r
+annoyance of his mother, who had set her heart on his standing for\r
+Parliament and had a vague idea that a chemist was a person who made up\r
+prescriptions. He was an excellent musician, however, as well, and\r
+played both the violin and the piano better than most amateurs. In\r
+fact, it was music that had first brought him and Dorian Gray\r
+together--music and that indefinable attraction that Dorian seemed to\r
+be able to exercise whenever he wished--and, indeed, exercised often\r
+without being conscious of it. They had met at Lady Berkshire's the\r
+night that Rubinstein played there, and after that used to be always\r
+seen together at the opera and wherever good music was going on. For\r
+eighteen months their intimacy lasted. Campbell was always either at\r
+Selby Royal or in Grosvenor Square. To him, as to many others, Dorian\r
+Gray was the type of everything that is wonderful and fascinating in\r
+life. Whether or not a quarrel had taken place between them no one\r
+ever knew. But suddenly people remarked that they scarcely spoke when\r
+they met and that Campbell seemed always to go away early from any\r
+party at which Dorian Gray was present. He had changed, too--was\r
+strangely melancholy at times, appeared almost to dislike hearing\r
+music, and would never himself play, giving as his excuse, when he was\r
+called upon, that he was so absorbed in science that he had no time\r
+left in which to practise. And this was certainly true. Every day he\r
+seemed to become more interested in biology, and his name appeared once\r
+or twice in some of the scientific reviews in connection with certain\r
+curious experiments.\r
+\r
+This was the man Dorian Gray was waiting for. Every second he kept\r
+glancing at the clock. As the minutes went by he became horribly\r
+agitated. At last he got up and began to pace up and down the room,\r
+looking like a beautiful caged thing. He took long stealthy strides.\r
+His hands were curiously cold.\r
+\r
+The suspense became unbearable. Time seemed to him to be crawling with\r
+feet of lead, while he by monstrous winds was being swept towards the\r
+jagged edge of some black cleft of precipice. He knew what was waiting\r
+for him there; saw it, indeed, and, shuddering, crushed with dank hands\r
+his burning lids as though he would have robbed the very brain of sight\r
+and driven the eyeballs back into their cave. It was useless. The\r
+brain had its own food on which it battened, and the imagination, made\r
+grotesque by terror, twisted and distorted as a living thing by pain,\r
+danced like some foul puppet on a stand and grinned through moving\r
+masks. Then, suddenly, time stopped for him. Yes: that blind,\r
+slow-breathing thing crawled no more, and horrible thoughts, time being\r
+dead, raced nimbly on in front, and dragged a hideous future from its\r
+grave, and showed it to him. He stared at it. Its very horror made\r
+him stone.\r
+\r
+At last the door opened and his servant entered. He turned glazed eyes\r
+upon him.\r
+\r
+"Mr. Campbell, sir," said the man.\r
+\r
+A sigh of relief broke from his parched lips, and the colour came back\r
+to his cheeks.\r
+\r
+"Ask him to come in at once, Francis." He felt that he was himself\r
+again. His mood of cowardice had passed away.\r
+\r
+The man bowed and retired. In a few moments, Alan Campbell walked in,\r
+looking very stern and rather pale, his pallor being intensified by his\r
+coal-black hair and dark eyebrows.\r
+\r
+"Alan! This is kind of you. I thank you for coming."\r
+\r
+"I had intended never to enter your house again, Gray. But you said it\r
+was a matter of life and death." His voice was hard and cold. He\r
+spoke with slow deliberation. There was a look of contempt in the\r
+steady searching gaze that he turned on Dorian. He kept his hands in\r
+the pockets of his Astrakhan coat, and seemed not to have noticed the\r
+gesture with which he had been greeted.\r
+\r
+"Yes: it is a matter of life and death, Alan, and to more than one\r
+person. Sit down."\r
+\r
+Campbell took a chair by the table, and Dorian sat opposite to him.\r
+The two men's eyes met. In Dorian's there was infinite pity. He knew\r
+that what he was going to do was dreadful.\r
+\r
+After a strained moment of silence, he leaned across and said, very\r
+quietly, but watching the effect of each word upon the face of him he\r
+had sent for, "Alan, in a locked room at the top of this house, a room\r
+to which nobody but myself has access, a dead man is seated at a table.\r
+He has been dead ten hours now. Don't stir, and don't look at me like\r
+that. Who the man is, why he died, how he died, are matters that do\r
+not concern you. What you have to do is this--"\r
+\r
+"Stop, Gray. I don't want to know anything further. Whether what you\r
+have told me is true or not true doesn't concern me. I entirely\r
+decline to be mixed up in your life. Keep your horrible secrets to\r
+yourself. They don't interest me any more."\r
+\r
+"Alan, they will have to interest you. This one will have to interest\r
+you. I am awfully sorry for you, Alan. But I can't help myself. You\r
+are the one man who is able to save me. I am forced to bring you into\r
+the matter. I have no option. Alan, you are scientific. You know\r
+about chemistry and things of that kind. You have made experiments.\r
+What you have got to do is to destroy the thing that is upstairs--to\r
+destroy it so that not a vestige of it will be left. Nobody saw this\r
+person come into the house. Indeed, at the present moment he is\r
+supposed to be in Paris. He will not be missed for months. When he is\r
+missed, there must be no trace of him found here. You, Alan, you must\r
+change him, and everything that belongs to him, into a handful of ashes\r
+that I may scatter in the air."\r
+\r
+"You are mad, Dorian."\r
+\r
+"Ah! I was waiting for you to call me Dorian."\r
+\r
+"You are mad, I tell you--mad to imagine that I would raise a finger to\r
+help you, mad to make this monstrous confession. I will have nothing\r
+to do with this matter, whatever it is. Do you think I am going to\r
+peril my reputation for you? What is it to me what devil's work you\r
+are up to?"\r
+\r
+"It was suicide, Alan."\r
+\r
+"I am glad of that. But who drove him to it? You, I should fancy."\r
+\r
+"Do you still refuse to do this for me?"\r
+\r
+"Of course I refuse. I will have absolutely nothing to do with it. I\r
+don't care what shame comes on you. You deserve it all. I should not\r
+be sorry to see you disgraced, publicly disgraced. How dare you ask\r
+me, of all men in the world, to mix myself up in this horror? I should\r
+have thought you knew more about people's characters. Your friend Lord\r
+Henry Wotton can't have taught you much about psychology, whatever else\r
+he has taught you. Nothing will induce me to stir a step to help you.\r
+You have come to the wrong man. Go to some of your friends. Don't\r
+come to me."\r
+\r
+"Alan, it was murder. I killed him. You don't know what he had made\r
+me suffer. Whatever my life is, he had more to do with the making or\r
+the marring of it than poor Harry has had. He may not have intended\r
+it, the result was the same."\r
+\r
+"Murder! Good God, Dorian, is that what you have come to? I shall not\r
+inform upon you. It is not my business. Besides, without my stirring\r
+in the matter, you are certain to be arrested. Nobody ever commits a\r
+crime without doing something stupid. But I will have nothing to do\r
+with it."\r
+\r
+"You must have something to do with it. Wait, wait a moment; listen to\r
+me. Only listen, Alan. All I ask of you is to perform a certain\r
+scientific experiment. You go to hospitals and dead-houses, and the\r
+horrors that you do there don't affect you. If in some hideous\r
+dissecting-room or fetid laboratory you found this man lying on a\r
+leaden table with red gutters scooped out in it for the blood to flow\r
+through, you would simply look upon him as an admirable subject. You\r
+would not turn a hair. You would not believe that you were doing\r
+anything wrong. On the contrary, you would probably feel that you were\r
+benefiting the human race, or increasing the sum of knowledge in the\r
+world, or gratifying intellectual curiosity, or something of that kind.\r
+What I want you to do is merely what you have often done before.\r
+Indeed, to destroy a body must be far less horrible than what you are\r
+accustomed to work at. And, remember, it is the only piece of evidence\r
+against me. If it is discovered, I am lost; and it is sure to be\r
+discovered unless you help me."\r
+\r
+"I have no desire to help you. You forget that. I am simply\r
+indifferent to the whole thing. It has nothing to do with me."\r
+\r
+"Alan, I entreat you. Think of the position I am in. Just before you\r
+came I almost fainted with terror. You may know terror yourself some\r
+day. No! don't think of that. Look at the matter purely from the\r
+scientific point of view. You don't inquire where the dead things on\r
+which you experiment come from. Don't inquire now. I have told you\r
+too much as it is. But I beg of you to do this. We were friends once,\r
+Alan."\r
+\r
+"Don't speak about those days, Dorian--they are dead."\r
+\r
+"The dead linger sometimes. The man upstairs will not go away. He is\r
+sitting at the table with bowed head and outstretched arms. Alan!\r
+Alan! If you don't come to my assistance, I am ruined. Why, they will\r
+hang me, Alan! Don't you understand? They will hang me for what I\r
+have done."\r
+\r
+"There is no good in prolonging this scene. I absolutely refuse to do\r
+anything in the matter. It is insane of you to ask me."\r
+\r
+"You refuse?"\r
+\r
+"Yes."\r
+\r
+"I entreat you, Alan."\r
+\r
+"It is useless."\r
+\r
+The same look of pity came into Dorian Gray's eyes. Then he stretched\r
+out his hand, took a piece of paper, and wrote something on it. He\r
+read it over twice, folded it carefully, and pushed it across the\r
+table. Having done this, he got up and went over to the window.\r
+\r
+Campbell looked at him in surprise, and then took up the paper, and\r
+opened it. As he read it, his face became ghastly pale and he fell\r
+back in his chair. A horrible sense of sickness came over him. He\r
+felt as if his heart was beating itself to death in some empty hollow.\r
+\r
+After two or three minutes of terrible silence, Dorian turned round and\r
+came and stood behind him, putting his hand upon his shoulder.\r
+\r
+"I am so sorry for you, Alan," he murmured, "but you leave me no\r
+alternative. I have a letter written already. Here it is. You see\r
+the address. If you don't help me, I must send it. If you don't help\r
+me, I will send it. You know what the result will be. But you are\r
+going to help me. It is impossible for you to refuse now. I tried to\r
+spare you. You will do me the justice to admit that. You were stern,\r
+harsh, offensive. You treated me as no man has ever dared to treat\r
+me--no living man, at any rate. I bore it all. Now it is for me to\r
+dictate terms."\r
+\r
+Campbell buried his face in his hands, and a shudder passed through him.\r
+\r
+"Yes, it is my turn to dictate terms, Alan. You know what they are.\r
+The thing is quite simple. Come, don't work yourself into this fever.\r
+The thing has to be done. Face it, and do it."\r
+\r
+A groan broke from Campbell's lips and he shivered all over. The\r
+ticking of the clock on the mantelpiece seemed to him to be dividing\r
+time into separate atoms of agony, each of which was too terrible to be\r
+borne. He felt as if an iron ring was being slowly tightened round his\r
+forehead, as if the disgrace with which he was threatened had already\r
+come upon him. The hand upon his shoulder weighed like a hand of lead.\r
+It was intolerable. It seemed to crush him.\r
+\r
+"Come, Alan, you must decide at once."\r
+\r
+"I cannot do it," he said, mechanically, as though words could alter\r
+things.\r
+\r
+"You must. You have no choice. Don't delay."\r
+\r
+He hesitated a moment. "Is there a fire in the room upstairs?"\r
+\r
+"Yes, there is a gas-fire with asbestos."\r
+\r
+"I shall have to go home and get some things from the laboratory."\r
+\r
+"No, Alan, you must not leave the house. Write out on a sheet of\r
+notepaper what you want and my servant will take a cab and bring the\r
+things back to you."\r
+\r
+Campbell scrawled a few lines, blotted them, and addressed an envelope\r
+to his assistant. Dorian took the note up and read it carefully. Then\r
+he rang the bell and gave it to his valet, with orders to return as\r
+soon as possible and to bring the things with him.\r
+\r
+As the hall door shut, Campbell started nervously, and having got up\r
+from the chair, went over to the chimney-piece. He was shivering with a\r
+kind of ague. For nearly twenty minutes, neither of the men spoke. A\r
+fly buzzed noisily about the room, and the ticking of the clock was\r
+like the beat of a hammer.\r
+\r
+As the chime struck one, Campbell turned round, and looking at Dorian\r
+Gray, saw that his eyes were filled with tears. There was something in\r
+the purity and refinement of that sad face that seemed to enrage him.\r
+"You are infamous, absolutely infamous!" he muttered.\r
+\r
+"Hush, Alan. You have saved my life," said Dorian.\r
+\r
+"Your life? Good heavens! what a life that is! You have gone from\r
+corruption to corruption, and now you have culminated in crime. In\r
+doing what I am going to do--what you force me to do--it is not of your\r
+life that I am thinking."\r
+\r
+"Ah, Alan," murmured Dorian with a sigh, "I wish you had a thousandth\r
+part of the pity for me that I have for you." He turned away as he\r
+spoke and stood looking out at the garden. Campbell made no answer.\r
+\r
+After about ten minutes a knock came to the door, and the servant\r
+entered, carrying a large mahogany chest of chemicals, with a long coil\r
+of steel and platinum wire and two rather curiously shaped iron clamps.\r
+\r
+"Shall I leave the things here, sir?" he asked Campbell.\r
+\r
+"Yes," said Dorian. "And I am afraid, Francis, that I have another\r
+errand for you. What is the name of the man at Richmond who supplies\r
+Selby with orchids?"\r
+\r
+"Harden, sir."\r
+\r
+"Yes--Harden. You must go down to Richmond at once, see Harden\r
+personally, and tell him to send twice as many orchids as I ordered,\r
+and to have as few white ones as possible. In fact, I don't want any\r
+white ones. It is a lovely day, Francis, and Richmond is a very pretty\r
+place--otherwise I wouldn't bother you about it."\r
+\r
+"No trouble, sir. At what time shall I be back?"\r
+\r
+Dorian looked at Campbell. "How long will your experiment take, Alan?"\r
+he said in a calm indifferent voice. The presence of a third person in\r
+the room seemed to give him extraordinary courage.\r
+\r
+Campbell frowned and bit his lip. "It will take about five hours," he\r
+answered.\r
+\r
+"It will be time enough, then, if you are back at half-past seven,\r
+Francis. Or stay: just leave my things out for dressing. You can\r
+have the evening to yourself. I am not dining at home, so I shall not\r
+want you."\r
+\r
+"Thank you, sir," said the man, leaving the room.\r
+\r
+"Now, Alan, there is not a moment to be lost. How heavy this chest is!\r
+I'll take it for you. You bring the other things." He spoke rapidly\r
+and in an authoritative manner. Campbell felt dominated by him. They\r
+left the room together.\r
+\r
+When they reached the top landing, Dorian took out the key and turned\r
+it in the lock. Then he stopped, and a troubled look came into his\r
+eyes. He shuddered. "I don't think I can go in, Alan," he murmured.\r
+\r
+"It is nothing to me. I don't require you," said Campbell coldly.\r
+\r
+Dorian half opened the door. As he did so, he saw the face of his\r
+portrait leering in the sunlight. On the floor in front of it the torn\r
+curtain was lying. He remembered that the night before he had\r
+forgotten, for the first time in his life, to hide the fatal canvas,\r
+and was about to rush forward, when he drew back with a shudder.\r
+\r
+What was that loathsome red dew that gleamed, wet and glistening, on\r
+one of the hands, as though the canvas had sweated blood? How horrible\r
+it was!--more horrible, it seemed to him for the moment, than the\r
+silent thing that he knew was stretched across the table, the thing\r
+whose grotesque misshapen shadow on the spotted carpet showed him that\r
+it had not stirred, but was still there, as he had left it.\r
+\r
+He heaved a deep breath, opened the door a little wider, and with\r
+half-closed eyes and averted head, walked quickly in, determined that\r
+he would not look even once upon the dead man. Then, stooping down and\r
+taking up the gold-and-purple hanging, he flung it right over the\r
+picture.\r
+\r
+There he stopped, feeling afraid to turn round, and his eyes fixed\r
+themselves on the intricacies of the pattern before him. He heard\r
+Campbell bringing in the heavy chest, and the irons, and the other\r
+things that he had required for his dreadful work. He began to wonder\r
+if he and Basil Hallward had ever met, and, if so, what they had\r
+thought of each other.\r
+\r
+"Leave me now," said a stern voice behind him.\r
+\r
+He turned and hurried out, just conscious that the dead man had been\r
+thrust back into the chair and that Campbell was gazing into a\r
+glistening yellow face. As he was going downstairs, he heard the key\r
+being turned in the lock.\r
+\r
+It was long after seven when Campbell came back into the library. He\r
+was pale, but absolutely calm. "I have done what you asked me to do,"\r
+he muttered. "And now, good-bye. Let us never see each other again."\r
+\r
+"You have saved me from ruin, Alan. I cannot forget that," said Dorian\r
+simply.\r
+\r
+As soon as Campbell had left, he went upstairs. There was a horrible\r
+smell of nitric acid in the room. But the thing that had been sitting\r
+at the table was gone.\r
+\r
+\r
+\r
+CHAPTER 15\r
+\r
+That evening, at eight-thirty, exquisitely dressed and wearing a large\r
+button-hole of Parma violets, Dorian Gray was ushered into Lady\r
+Narborough's drawing-room by bowing servants. His forehead was\r
+throbbing with maddened nerves, and he felt wildly excited, but his\r
+manner as he bent over his hostess's hand was as easy and graceful as\r
+ever. Perhaps one never seems so much at one's ease as when one has to\r
+play a part. Certainly no one looking at Dorian Gray that night could\r
+have believed that he had passed through a tragedy as horrible as any\r
+tragedy of our age. Those finely shaped fingers could never have\r
+clutched a knife for sin, nor those smiling lips have cried out on God\r
+and goodness. He himself could not help wondering at the calm of his\r
+demeanour, and for a moment felt keenly the terrible pleasure of a\r
+double life.\r
+\r
+It was a small party, got up rather in a hurry by Lady Narborough, who\r
+was a very clever woman with what Lord Henry used to describe as the\r
+remains of really remarkable ugliness. She had proved an excellent\r
+wife to one of our most tedious ambassadors, and having buried her\r
+husband properly in a marble mausoleum, which she had herself designed,\r
+and married off her daughters to some rich, rather elderly men, she\r
+devoted herself now to the pleasures of French fiction, French cookery,\r
+and French _esprit_ when she could get it.\r
+\r
+Dorian was one of her especial favourites, and she always told him that\r
+she was extremely glad she had not met him in early life. "I know, my\r
+dear, I should have fallen madly in love with you," she used to say,\r
+"and thrown my bonnet right over the mills for your sake. It is most\r
+fortunate that you were not thought of at the time. As it was, our\r
+bonnets were so unbecoming, and the mills were so occupied in trying to\r
+raise the wind, that I never had even a flirtation with anybody.\r
+However, that was all Narborough's fault. He was dreadfully\r
+short-sighted, and there is no pleasure in taking in a husband who\r
+never sees anything."\r
+\r
+Her guests this evening were rather tedious. The fact was, as she\r
+explained to Dorian, behind a very shabby fan, one of her married\r
+daughters had come up quite suddenly to stay with her, and, to make\r
+matters worse, had actually brought her husband with her. "I think it\r
+is most unkind of her, my dear," she whispered. "Of course I go and\r
+stay with them every summer after I come from Homburg, but then an old\r
+woman like me must have fresh air sometimes, and besides, I really wake\r
+them up. You don't know what an existence they lead down there. It is\r
+pure unadulterated country life. They get up early, because they have\r
+so much to do, and go to bed early, because they have so little to\r
+think about. There has not been a scandal in the neighbourhood since\r
+the time of Queen Elizabeth, and consequently they all fall asleep\r
+after dinner. You shan't sit next either of them. You shall sit by me\r
+and amuse me."\r
+\r
+Dorian murmured a graceful compliment and looked round the room. Yes:\r
+it was certainly a tedious party. Two of the people he had never seen\r
+before, and the others consisted of Ernest Harrowden, one of those\r
+middle-aged mediocrities so common in London clubs who have no enemies,\r
+but are thoroughly disliked by their friends; Lady Ruxton, an\r
+overdressed woman of forty-seven, with a hooked nose, who was always\r
+trying to get herself compromised, but was so peculiarly plain that to\r
+her great disappointment no one would ever believe anything against\r
+her; Mrs. Erlynne, a pushing nobody, with a delightful lisp and\r
+Venetian-red hair; Lady Alice Chapman, his hostess's daughter, a dowdy\r
+dull girl, with one of those characteristic British faces that, once\r
+seen, are never remembered; and her husband, a red-cheeked,\r
+white-whiskered creature who, like so many of his class, was under the\r
+impression that inordinate joviality can atone for an entire lack of\r
+ideas.\r
+\r
+He was rather sorry he had come, till Lady Narborough, looking at the\r
+great ormolu gilt clock that sprawled in gaudy curves on the\r
+mauve-draped mantelshelf, exclaimed: "How horrid of Henry Wotton to be\r
+so late! I sent round to him this morning on chance and he promised\r
+faithfully not to disappoint me."\r
+\r
+It was some consolation that Harry was to be there, and when the door\r
+opened and he heard his slow musical voice lending charm to some\r
+insincere apology, he ceased to feel bored.\r
+\r
+But at dinner he could not eat anything. Plate after plate went away\r
+untasted. Lady Narborough kept scolding him for what she called "an\r
+insult to poor Adolphe, who invented the _menu_ specially for you," and\r
+now and then Lord Henry looked across at him, wondering at his silence\r
+and abstracted manner. From time to time the butler filled his glass\r
+with champagne. He drank eagerly, and his thirst seemed to increase.\r
+\r
+"Dorian," said Lord Henry at last, as the _chaud-froid_ was being handed\r
+round, "what is the matter with you to-night? You are quite out of\r
+sorts."\r
+\r
+"I believe he is in love," cried Lady Narborough, "and that he is\r
+afraid to tell me for fear I should be jealous. He is quite right. I\r
+certainly should."\r
+\r
+"Dear Lady Narborough," murmured Dorian, smiling, "I have not been in\r
+love for a whole week--not, in fact, since Madame de Ferrol left town."\r
+\r
+"How you men can fall in love with that woman!" exclaimed the old lady.\r
+"I really cannot understand it."\r
+\r
+"It is simply because she remembers you when you were a little girl,\r
+Lady Narborough," said Lord Henry. "She is the one link between us and\r
+your short frocks."\r
+\r
+"She does not remember my short frocks at all, Lord Henry. But I\r
+remember her very well at Vienna thirty years ago, and how _decolletee_\r
+she was then."\r
+\r
+"She is still _decolletee_," he answered, taking an olive in his long\r
+fingers; "and when she is in a very smart gown she looks like an\r
+_edition de luxe_ of a bad French novel. She is really wonderful, and\r
+full of surprises. Her capacity for family affection is extraordinary.\r
+When her third husband died, her hair turned quite gold from grief."\r
+\r
+"How can you, Harry!" cried Dorian.\r
+\r
+"It is a most romantic explanation," laughed the hostess. "But her\r
+third husband, Lord Henry! You don't mean to say Ferrol is the fourth?"\r
+\r
+"Certainly, Lady Narborough."\r
+\r
+"I don't believe a word of it."\r
+\r
+"Well, ask Mr. Gray. He is one of her most intimate friends."\r
+\r
+"Is it true, Mr. Gray?"\r
+\r
+"She assures me so, Lady Narborough," said Dorian. "I asked her\r
+whether, like Marguerite de Navarre, she had their hearts embalmed and\r
+hung at her girdle. She told me she didn't, because none of them had\r
+had any hearts at all."\r
+\r
+"Four husbands! Upon my word that is _trop de zele_."\r
+\r
+"_Trop d'audace_, I tell her," said Dorian.\r
+\r
+"Oh! she is audacious enough for anything, my dear. And what is Ferrol\r
+like? I don't know him."\r
+\r
+"The husbands of very beautiful women belong to the criminal classes,"\r
+said Lord Henry, sipping his wine.\r
+\r
+Lady Narborough hit him with her fan. "Lord Henry, I am not at all\r
+surprised that the world says that you are extremely wicked."\r
+\r
+"But what world says that?" asked Lord Henry, elevating his eyebrows.\r
+"It can only be the next world. This world and I are on excellent\r
+terms."\r
+\r
+"Everybody I know says you are very wicked," cried the old lady,\r
+shaking her head.\r
+\r
+Lord Henry looked serious for some moments. "It is perfectly\r
+monstrous," he said, at last, "the way people go about nowadays saying\r
+things against one behind one's back that are absolutely and entirely\r
+true."\r
+\r
+"Isn't he incorrigible?" cried Dorian, leaning forward in his chair.\r
+\r
+"I hope so," said his hostess, laughing. "But really, if you all\r
+worship Madame de Ferrol in this ridiculous way, I shall have to marry\r
+again so as to be in the fashion."\r
+\r
+"You will never marry again, Lady Narborough," broke in Lord Henry.\r
+"You were far too happy. When a woman marries again, it is because she\r
+detested her first husband. When a man marries again, it is because he\r
+adored his first wife. Women try their luck; men risk theirs."\r
+\r
+"Narborough wasn't perfect," cried the old lady.\r
+\r
+"If he had been, you would not have loved him, my dear lady," was the\r
+rejoinder. "Women love us for our defects. If we have enough of them,\r
+they will forgive us everything, even our intellects. You will never\r
+ask me to dinner again after saying this, I am afraid, Lady Narborough,\r
+but it is quite true."\r
+\r
+"Of course it is true, Lord Henry. If we women did not love you for\r
+your defects, where would you all be? Not one of you would ever be\r
+married. You would be a set of unfortunate bachelors. Not, however,\r
+that that would alter you much. Nowadays all the married men live like\r
+bachelors, and all the bachelors like married men."\r
+\r
+"_Fin de siecle_," murmured Lord Henry.\r
+\r
+"_Fin du globe_," answered his hostess.\r
+\r
+"I wish it were _fin du globe_," said Dorian with a sigh. "Life is a\r
+great disappointment."\r
+\r
+"Ah, my dear," cried Lady Narborough, putting on her gloves, "don't\r
+tell me that you have exhausted life. When a man says that one knows\r
+that life has exhausted him. Lord Henry is very wicked, and I\r
+sometimes wish that I had been; but you are made to be good--you look\r
+so good. I must find you a nice wife. Lord Henry, don't you think\r
+that Mr. Gray should get married?"\r
+\r
+"I am always telling him so, Lady Narborough," said Lord Henry with a\r
+bow.\r
+\r
+"Well, we must look out for a suitable match for him. I shall go\r
+through Debrett carefully to-night and draw out a list of all the\r
+eligible young ladies."\r
+\r
+"With their ages, Lady Narborough?" asked Dorian.\r
+\r
+"Of course, with their ages, slightly edited. But nothing must be done\r
+in a hurry. I want it to be what _The Morning Post_ calls a suitable\r
+alliance, and I want you both to be happy."\r
+\r
+"What nonsense people talk about happy marriages!" exclaimed Lord\r
+Henry. "A man can be happy with any woman, as long as he does not love\r
+her."\r
+\r
+"Ah! what a cynic you are!" cried the old lady, pushing back her chair\r
+and nodding to Lady Ruxton. "You must come and dine with me soon\r
+again. You are really an admirable tonic, much better than what Sir\r
+Andrew prescribes for me. You must tell me what people you would like\r
+to meet, though. I want it to be a delightful gathering."\r
+\r
+"I like men who have a future and women who have a past," he answered.\r
+"Or do you think that would make it a petticoat party?"\r
+\r
+"I fear so," she said, laughing, as she stood up. "A thousand pardons,\r
+my dear Lady Ruxton," she added, "I didn't see you hadn't finished your\r
+cigarette."\r
+\r
+"Never mind, Lady Narborough. I smoke a great deal too much. I am\r
+going to limit myself, for the future."\r
+\r
+"Pray don't, Lady Ruxton," said Lord Henry. "Moderation is a fatal\r
+thing. Enough is as bad as a meal. More than enough is as good as a\r
+feast."\r
+\r
+Lady Ruxton glanced at him curiously. "You must come and explain that\r
+to me some afternoon, Lord Henry. It sounds a fascinating theory," she\r
+murmured, as she swept out of the room.\r
+\r
+"Now, mind you don't stay too long over your politics and scandal,"\r
+cried Lady Narborough from the door. "If you do, we are sure to\r
+squabble upstairs."\r
+\r
+The men laughed, and Mr. Chapman got up solemnly from the foot of the\r
+table and came up to the top. Dorian Gray changed his seat and went\r
+and sat by Lord Henry. Mr. Chapman began to talk in a loud voice about\r
+the situation in the House of Commons. He guffawed at his adversaries.\r
+The word _doctrinaire_--word full of terror to the British\r
+mind--reappeared from time to time between his explosions. An\r
+alliterative prefix served as an ornament of oratory. He hoisted the\r
+Union Jack on the pinnacles of thought. The inherited stupidity of the\r
+race--sound English common sense he jovially termed it--was shown to be\r
+the proper bulwark for society.\r
+\r
+A smile curved Lord Henry's lips, and he turned round and looked at\r
+Dorian.\r
+\r
+"Are you better, my dear fellow?" he asked. "You seemed rather out of\r
+sorts at dinner."\r
+\r
+"I am quite well, Harry. I am tired. That is all."\r
+\r
+"You were charming last night. The little duchess is quite devoted to\r
+you. She tells me she is going down to Selby."\r
+\r
+"She has promised to come on the twentieth."\r
+\r
+"Is Monmouth to be there, too?"\r
+\r
+"Oh, yes, Harry."\r
+\r
+"He bores me dreadfully, almost as much as he bores her. She is very\r
+clever, too clever for a woman. She lacks the indefinable charm of\r
+weakness. It is the feet of clay that make the gold of the image\r
+precious. Her feet are very pretty, but they are not feet of clay.\r
+White porcelain feet, if you like. They have been through the fire,\r
+and what fire does not destroy, it hardens. She has had experiences."\r
+\r
+"How long has she been married?" asked Dorian.\r
+\r
+"An eternity, she tells me. I believe, according to the peerage, it is\r
+ten years, but ten years with Monmouth must have been like eternity,\r
+with time thrown in. Who else is coming?"\r
+\r
+"Oh, the Willoughbys, Lord Rugby and his wife, our hostess, Geoffrey\r
+Clouston, the usual set. I have asked Lord Grotrian."\r
+\r
+"I like him," said Lord Henry. "A great many people don't, but I find\r
+him charming. He atones for being occasionally somewhat overdressed by\r
+being always absolutely over-educated. He is a very modern type."\r
+\r
+"I don't know if he will be able to come, Harry. He may have to go to\r
+Monte Carlo with his father."\r
+\r
+"Ah! what a nuisance people's people are! Try and make him come. By\r
+the way, Dorian, you ran off very early last night. You left before\r
+eleven. What did you do afterwards? Did you go straight home?"\r
+\r
+Dorian glanced at him hurriedly and frowned.\r
+\r
+"No, Harry," he said at last, "I did not get home till nearly three."\r
+\r
+"Did you go to the club?"\r
+\r
+"Yes," he answered. Then he bit his lip. "No, I don't mean that. I\r
+didn't go to the club. I walked about. I forget what I did.... How\r
+inquisitive you are, Harry! You always want to know what one has been\r
+doing. I always want to forget what I have been doing. I came in at\r
+half-past two, if you wish to know the exact time. I had left my\r
+latch-key at home, and my servant had to let me in. If you want any\r
+corroborative evidence on the subject, you can ask him."\r
+\r
+Lord Henry shrugged his shoulders. "My dear fellow, as if I cared!\r
+Let us go up to the drawing-room. No sherry, thank you, Mr. Chapman.\r
+Something has happened to you, Dorian. Tell me what it is. You are\r
+not yourself to-night."\r
+\r
+"Don't mind me, Harry. I am irritable, and out of temper. I shall\r
+come round and see you to-morrow, or next day. Make my excuses to Lady\r
+Narborough. I shan't go upstairs. I shall go home. I must go home."\r
+\r
+"All right, Dorian. I dare say I shall see you to-morrow at tea-time.\r
+The duchess is coming."\r
+\r
+"I will try to be there, Harry," he said, leaving the room. As he\r
+drove back to his own house, he was conscious that the sense of terror\r
+he thought he had strangled had come back to him. Lord Henry's casual\r
+questioning had made him lose his nerve for the moment, and he wanted\r
+his nerve still. Things that were dangerous had to be destroyed. He\r
+winced. He hated the idea of even touching them.\r
+\r
+Yet it had to be done. He realized that, and when he had locked the\r
+door of his library, he opened the secret press into which he had\r
+thrust Basil Hallward's coat and bag. A huge fire was blazing. He\r
+piled another log on it. The smell of the singeing clothes and burning\r
+leather was horrible. It took him three-quarters of an hour to consume\r
+everything. At the end he felt faint and sick, and having lit some\r
+Algerian pastilles in a pierced copper brazier, he bathed his hands and\r
+forehead with a cool musk-scented vinegar.\r
+\r
+Suddenly he started. His eyes grew strangely bright, and he gnawed\r
+nervously at his underlip. Between two of the windows stood a large\r
+Florentine cabinet, made out of ebony and inlaid with ivory and blue\r
+lapis. He watched it as though it were a thing that could fascinate\r
+and make afraid, as though it held something that he longed for and yet\r
+almost loathed. His breath quickened. A mad craving came over him.\r
+He lit a cigarette and then threw it away. His eyelids drooped till\r
+the long fringed lashes almost touched his cheek. But he still watched\r
+the cabinet. At last he got up from the sofa on which he had been\r
+lying, went over to it, and having unlocked it, touched some hidden\r
+spring. A triangular drawer passed slowly out. His fingers moved\r
+instinctively towards it, dipped in, and closed on something. It was a\r
+small Chinese box of black and gold-dust lacquer, elaborately wrought,\r
+the sides patterned with curved waves, and the silken cords hung with\r
+round crystals and tasselled in plaited metal threads. He opened it.\r
+Inside was a green paste, waxy in lustre, the odour curiously heavy and\r
+persistent.\r
+\r
+He hesitated for some moments, with a strangely immobile smile upon his\r
+face. Then shivering, though the atmosphere of the room was terribly\r
+hot, he drew himself up and glanced at the clock. It was twenty\r
+minutes to twelve. He put the box back, shutting the cabinet doors as\r
+he did so, and went into his bedroom.\r
+\r
+As midnight was striking bronze blows upon the dusky air, Dorian Gray,\r
+dressed commonly, and with a muffler wrapped round his throat, crept\r
+quietly out of his house. In Bond Street he found a hansom with a good\r
+horse. He hailed it and in a low voice gave the driver an address.\r
+\r
+The man shook his head. "It is too far for me," he muttered.\r
+\r
+"Here is a sovereign for you," said Dorian. "You shall have another if\r
+you drive fast."\r
+\r
+"All right, sir," answered the man, "you will be there in an hour," and\r
+after his fare had got in he turned his horse round and drove rapidly\r
+towards the river.\r
+\r
+\r
+\r
+CHAPTER 16\r
+\r
+A cold rain began to fall, and the blurred street-lamps looked ghastly\r
+in the dripping mist. The public-houses were just closing, and dim men\r
+and women were clustering in broken groups round their doors. From\r
+some of the bars came the sound of horrible laughter. In others,\r
+drunkards brawled and screamed.\r
+\r
+Lying back in the hansom, with his hat pulled over his forehead, Dorian\r
+Gray watched with listless eyes the sordid shame of the great city, and\r
+now and then he repeated to himself the words that Lord Henry had said\r
+to him on the first day they had met, "To cure the soul by means of the\r
+senses, and the senses by means of the soul." Yes, that was the\r
+secret. He had often tried it, and would try it again now. There were\r
+opium dens where one could buy oblivion, dens of horror where the\r
+memory of old sins could be destroyed by the madness of sins that were\r
+new.\r
+\r
+The moon hung low in the sky like a yellow skull. From time to time a\r
+huge misshapen cloud stretched a long arm across and hid it. The\r
+gas-lamps grew fewer, and the streets more narrow and gloomy. Once the\r
+man lost his way and had to drive back half a mile. A steam rose from\r
+the horse as it splashed up the puddles. The sidewindows of the hansom\r
+were clogged with a grey-flannel mist.\r
+\r
+"To cure the soul by means of the senses, and the senses by means of\r
+the soul!" How the words rang in his ears! His soul, certainly, was\r
+sick to death. Was it true that the senses could cure it? Innocent\r
+blood had been spilled. What could atone for that? Ah! for that there\r
+was no atonement; but though forgiveness was impossible, forgetfulness\r
+was possible still, and he was determined to forget, to stamp the thing\r
+out, to crush it as one would crush the adder that had stung one.\r
+Indeed, what right had Basil to have spoken to him as he had done? Who\r
+had made him a judge over others? He had said things that were\r
+dreadful, horrible, not to be endured.\r
+\r
+On and on plodded the hansom, going slower, it seemed to him, at each\r
+step. He thrust up the trap and called to the man to drive faster.\r
+The hideous hunger for opium began to gnaw at him. His throat burned\r
+and his delicate hands twitched nervously together. He struck at the\r
+horse madly with his stick. The driver laughed and whipped up. He\r
+laughed in answer, and the man was silent.\r
+\r
+The way seemed interminable, and the streets like the black web of some\r
+sprawling spider. The monotony became unbearable, and as the mist\r
+thickened, he felt afraid.\r
+\r
+Then they passed by lonely brickfields. The fog was lighter here, and\r
+he could see the strange, bottle-shaped kilns with their orange,\r
+fanlike tongues of fire. A dog barked as they went by, and far away in\r
+the darkness some wandering sea-gull screamed. The horse stumbled in a\r
+rut, then swerved aside and broke into a gallop.\r
+\r
+After some time they left the clay road and rattled again over\r
+rough-paven streets. Most of the windows were dark, but now and then\r
+fantastic shadows were silhouetted against some lamplit blind. He\r
+watched them curiously. They moved like monstrous marionettes and made\r
+gestures like live things. He hated them. A dull rage was in his\r
+heart. As they turned a corner, a woman yelled something at them from\r
+an open door, and two men ran after the hansom for about a hundred\r
+yards. The driver beat at them with his whip.\r
+\r
+It is said that passion makes one think in a circle. Certainly with\r
+hideous iteration the bitten lips of Dorian Gray shaped and reshaped\r
+those subtle words that dealt with soul and sense, till he had found in\r
+them the full expression, as it were, of his mood, and justified, by\r
+intellectual approval, passions that without such justification would\r
+still have dominated his temper. From cell to cell of his brain crept\r
+the one thought; and the wild desire to live, most terrible of all\r
+man's appetites, quickened into force each trembling nerve and fibre.\r
+Ugliness that had once been hateful to him because it made things real,\r
+became dear to him now for that very reason. Ugliness was the one\r
+reality. The coarse brawl, the loathsome den, the crude violence of\r
+disordered life, the very vileness of thief and outcast, were more\r
+vivid, in their intense actuality of impression, than all the gracious\r
+shapes of art, the dreamy shadows of song. They were what he needed\r
+for forgetfulness. In three days he would be free.\r
+\r
+Suddenly the man drew up with a jerk at the top of a dark lane. Over\r
+the low roofs and jagged chimney-stacks of the houses rose the black\r
+masts of ships. Wreaths of white mist clung like ghostly sails to the\r
+yards.\r
+\r
+"Somewhere about here, sir, ain't it?" he asked huskily through the\r
+trap.\r
+\r
+Dorian started and peered round. "This will do," he answered, and\r
+having got out hastily and given the driver the extra fare he had\r
+promised him, he walked quickly in the direction of the quay. Here and\r
+there a lantern gleamed at the stern of some huge merchantman. The\r
+light shook and splintered in the puddles. A red glare came from an\r
+outward-bound steamer that was coaling. The slimy pavement looked like\r
+a wet mackintosh.\r
+\r
+He hurried on towards the left, glancing back now and then to see if he\r
+was being followed. In about seven or eight minutes he reached a small\r
+shabby house that was wedged in between two gaunt factories. In one of\r
+the top-windows stood a lamp. He stopped and gave a peculiar knock.\r
+\r
+After a little time he heard steps in the passage and the chain being\r
+unhooked. The door opened quietly, and he went in without saying a\r
+word to the squat misshapen figure that flattened itself into the\r
+shadow as he passed. At the end of the hall hung a tattered green\r
+curtain that swayed and shook in the gusty wind which had followed him\r
+in from the street. He dragged it aside and entered a long low room\r
+which looked as if it had once been a third-rate dancing-saloon. Shrill\r
+flaring gas-jets, dulled and distorted in the fly-blown mirrors that\r
+faced them, were ranged round the walls. Greasy reflectors of ribbed\r
+tin backed them, making quivering disks of light. The floor was\r
+covered with ochre-coloured sawdust, trampled here and there into mud,\r
+and stained with dark rings of spilled liquor. Some Malays were\r
+crouching by a little charcoal stove, playing with bone counters and\r
+showing their white teeth as they chattered. In one corner, with his\r
+head buried in his arms, a sailor sprawled over a table, and by the\r
+tawdrily painted bar that ran across one complete side stood two\r
+haggard women, mocking an old man who was brushing the sleeves of his\r
+coat with an expression of disgust. "He thinks he's got red ants on\r
+him," laughed one of them, as Dorian passed by. The man looked at her\r
+in terror and began to whimper.\r
+\r
+At the end of the room there was a little staircase, leading to a\r
+darkened chamber. As Dorian hurried up its three rickety steps, the\r
+heavy odour of opium met him. He heaved a deep breath, and his\r
+nostrils quivered with pleasure. When he entered, a young man with\r
+smooth yellow hair, who was bending over a lamp lighting a long thin\r
+pipe, looked up at him and nodded in a hesitating manner.\r
+\r
+"You here, Adrian?" muttered Dorian.\r
+\r
+"Where else should I be?" he answered, listlessly. "None of the chaps\r
+will speak to me now."\r
+\r
+"I thought you had left England."\r
+\r
+"Darlington is not going to do anything. My brother paid the bill at\r
+last. George doesn't speak to me either.... I don't care," he added\r
+with a sigh. "As long as one has this stuff, one doesn't want friends.\r
+I think I have had too many friends."\r
+\r
+Dorian winced and looked round at the grotesque things that lay in such\r
+fantastic postures on the ragged mattresses. The twisted limbs, the\r
+gaping mouths, the staring lustreless eyes, fascinated him. He knew in\r
+what strange heavens they were suffering, and what dull hells were\r
+teaching them the secret of some new joy. They were better off than he\r
+was. He was prisoned in thought. Memory, like a horrible malady, was\r
+eating his soul away. From time to time he seemed to see the eyes of\r
+Basil Hallward looking at him. Yet he felt he could not stay. The\r
+presence of Adrian Singleton troubled him. He wanted to be where no\r
+one would know who he was. He wanted to escape from himself.\r
+\r
+"I am going on to the other place," he said after a pause.\r
+\r
+"On the wharf?"\r
+\r
+"Yes."\r
+\r
+"That mad-cat is sure to be there. They won't have her in this place\r
+now."\r
+\r
+Dorian shrugged his shoulders. "I am sick of women who love one.\r
+Women who hate one are much more interesting. Besides, the stuff is\r
+better."\r
+\r
+"Much the same."\r
+\r
+"I like it better. Come and have something to drink. I must have\r
+something."\r
+\r
+"I don't want anything," murmured the young man.\r
+\r
+"Never mind."\r
+\r
+Adrian Singleton rose up wearily and followed Dorian to the bar. A\r
+half-caste, in a ragged turban and a shabby ulster, grinned a hideous\r
+greeting as he thrust a bottle of brandy and two tumblers in front of\r
+them. The women sidled up and began to chatter. Dorian turned his\r
+back on them and said something in a low voice to Adrian Singleton.\r
+\r
+A crooked smile, like a Malay crease, writhed across the face of one of\r
+the women. "We are very proud to-night," she sneered.\r
+\r
+"For God's sake don't talk to me," cried Dorian, stamping his foot on\r
+the ground. "What do you want? Money? Here it is. Don't ever talk\r
+to me again."\r
+\r
+Two red sparks flashed for a moment in the woman's sodden eyes, then\r
+flickered out and left them dull and glazed. She tossed her head and\r
+raked the coins off the counter with greedy fingers. Her companion\r
+watched her enviously.\r
+\r
+"It's no use," sighed Adrian Singleton. "I don't care to go back.\r
+What does it matter? I am quite happy here."\r
+\r
+"You will write to me if you want anything, won't you?" said Dorian,\r
+after a pause.\r
+\r
+"Perhaps."\r
+\r
+"Good night, then."\r
+\r
+"Good night," answered the young man, passing up the steps and wiping\r
+his parched mouth with a handkerchief.\r
+\r
+Dorian walked to the door with a look of pain in his face. As he drew\r
+the curtain aside, a hideous laugh broke from the painted lips of the\r
+woman who had taken his money. "There goes the devil's bargain!" she\r
+hiccoughed, in a hoarse voice.\r
+\r
+"Curse you!" he answered, "don't call me that."\r
+\r
+She snapped her fingers. "Prince Charming is what you like to be\r
+called, ain't it?" she yelled after him.\r
+\r
+The drowsy sailor leaped to his feet as she spoke, and looked wildly\r
+round. The sound of the shutting of the hall door fell on his ear. He\r
+rushed out as if in pursuit.\r
+\r
+Dorian Gray hurried along the quay through the drizzling rain. His\r
+meeting with Adrian Singleton had strangely moved him, and he wondered\r
+if the ruin of that young life was really to be laid at his door, as\r
+Basil Hallward had said to him with such infamy of insult. He bit his\r
+lip, and for a few seconds his eyes grew sad. Yet, after all, what did\r
+it matter to him? One's days were too brief to take the burden of\r
+another's errors on one's shoulders. Each man lived his own life and\r
+paid his own price for living it. The only pity was one had to pay so\r
+often for a single fault. One had to pay over and over again, indeed.\r
+In her dealings with man, destiny never closed her accounts.\r
+\r
+There are moments, psychologists tell us, when the passion for sin, or\r
+for what the world calls sin, so dominates a nature that every fibre of\r
+the body, as every cell of the brain, seems to be instinct with fearful\r
+impulses. Men and women at such moments lose the freedom of their\r
+will. They move to their terrible end as automatons move. Choice is\r
+taken from them, and conscience is either killed, or, if it lives at\r
+all, lives but to give rebellion its fascination and disobedience its\r
+charm. For all sins, as theologians weary not of reminding us, are\r
+sins of disobedience. When that high spirit, that morning star of\r
+evil, fell from heaven, it was as a rebel that he fell.\r
+\r
+Callous, concentrated on evil, with stained mind, and soul hungry for\r
+rebellion, Dorian Gray hastened on, quickening his step as he went, but\r
+as he darted aside into a dim archway, that had served him often as a\r
+short cut to the ill-famed place where he was going, he felt himself\r
+suddenly seized from behind, and before he had time to defend himself,\r
+he was thrust back against the wall, with a brutal hand round his\r
+throat.\r
+\r
+He struggled madly for life, and by a terrible effort wrenched the\r
+tightening fingers away. In a second he heard the click of a revolver,\r
+and saw the gleam of a polished barrel, pointing straight at his head,\r
+and the dusky form of a short, thick-set man facing him.\r
+\r
+"What do you want?" he gasped.\r
+\r
+"Keep quiet," said the man. "If you stir, I shoot you."\r
+\r
+"You are mad. What have I done to you?"\r
+\r
+"You wrecked the life of Sibyl Vane," was the answer, "and Sibyl Vane\r
+was my sister. She killed herself. I know it. Her death is at your\r
+door. I swore I would kill you in return. For years I have sought\r
+you. I had no clue, no trace. The two people who could have described\r
+you were dead. I knew nothing of you but the pet name she used to call\r
+you. I heard it to-night by chance. Make your peace with God, for\r
+to-night you are going to die."\r
+\r
+Dorian Gray grew sick with fear. "I never knew her," he stammered. "I\r
+never heard of her. You are mad."\r
+\r
+"You had better confess your sin, for as sure as I am James Vane, you\r
+are going to die." There was a horrible moment. Dorian did not know\r
+what to say or do. "Down on your knees!" growled the man. "I give you\r
+one minute to make your peace--no more. I go on board to-night for\r
+India, and I must do my job first. One minute. That's all."\r
+\r
+Dorian's arms fell to his side. Paralysed with terror, he did not know\r
+what to do. Suddenly a wild hope flashed across his brain. "Stop," he\r
+cried. "How long ago is it since your sister died? Quick, tell me!"\r
+\r
+"Eighteen years," said the man. "Why do you ask me? What do years\r
+matter?"\r
+\r
+"Eighteen years," laughed Dorian Gray, with a touch of triumph in his\r
+voice. "Eighteen years! Set me under the lamp and look at my face!"\r
+\r
+James Vane hesitated for a moment, not understanding what was meant.\r
+Then he seized Dorian Gray and dragged him from the archway.\r
+\r
+Dim and wavering as was the wind-blown light, yet it served to show him\r
+the hideous error, as it seemed, into which he had fallen, for the face\r
+of the man he had sought to kill had all the bloom of boyhood, all the\r
+unstained purity of youth. He seemed little more than a lad of twenty\r
+summers, hardly older, if older indeed at all, than his sister had been\r
+when they had parted so many years ago. It was obvious that this was\r
+not the man who had destroyed her life.\r
+\r
+He loosened his hold and reeled back. "My God! my God!" he cried, "and\r
+I would have murdered you!"\r
+\r
+Dorian Gray drew a long breath. "You have been on the brink of\r
+committing a terrible crime, my man," he said, looking at him sternly.\r
+"Let this be a warning to you not to take vengeance into your own\r
+hands."\r
+\r
+"Forgive me, sir," muttered James Vane. "I was deceived. A chance\r
+word I heard in that damned den set me on the wrong track."\r
+\r
+"You had better go home and put that pistol away, or you may get into\r
+trouble," said Dorian, turning on his heel and going slowly down the\r
+street.\r
+\r
+James Vane stood on the pavement in horror. He was trembling from head\r
+to foot. After a little while, a black shadow that had been creeping\r
+along the dripping wall moved out into the light and came close to him\r
+with stealthy footsteps. He felt a hand laid on his arm and looked\r
+round with a start. It was one of the women who had been drinking at\r
+the bar.\r
+\r
+"Why didn't you kill him?" she hissed out, putting haggard face quite\r
+close to his. "I knew you were following him when you rushed out from\r
+Daly's. You fool! You should have killed him. He has lots of money,\r
+and he's as bad as bad."\r
+\r
+"He is not the man I am looking for," he answered, "and I want no man's\r
+money. I want a man's life. The man whose life I want must be nearly\r
+forty now. This one is little more than a boy. Thank God, I have not\r
+got his blood upon my hands."\r
+\r
+The woman gave a bitter laugh. "Little more than a boy!" she sneered.\r
+"Why, man, it's nigh on eighteen years since Prince Charming made me\r
+what I am."\r
+\r
+"You lie!" cried James Vane.\r
+\r
+She raised her hand up to heaven. "Before God I am telling the truth,"\r
+she cried.\r
+\r
+"Before God?"\r
+\r
+"Strike me dumb if it ain't so. He is the worst one that comes here.\r
+They say he has sold himself to the devil for a pretty face. It's nigh\r
+on eighteen years since I met him. He hasn't changed much since then.\r
+I have, though," she added, with a sickly leer.\r
+\r
+"You swear this?"\r
+\r
+"I swear it," came in hoarse echo from her flat mouth. "But don't give\r
+me away to him," she whined; "I am afraid of him. Let me have some\r
+money for my night's lodging."\r
+\r
+He broke from her with an oath and rushed to the corner of the street,\r
+but Dorian Gray had disappeared. When he looked back, the woman had\r
+vanished also.\r
+\r
+\r
+\r
+CHAPTER 17\r
+\r
+A week later Dorian Gray was sitting in the conservatory at Selby\r
+Royal, talking to the pretty Duchess of Monmouth, who with her husband,\r
+a jaded-looking man of sixty, was amongst his guests. It was tea-time,\r
+and the mellow light of the huge, lace-covered lamp that stood on the\r
+table lit up the delicate china and hammered silver of the service at\r
+which the duchess was presiding. Her white hands were moving daintily\r
+among the cups, and her full red lips were smiling at something that\r
+Dorian had whispered to her. Lord Henry was lying back in a\r
+silk-draped wicker chair, looking at them. On a peach-coloured divan\r
+sat Lady Narborough, pretending to listen to the duke's description of\r
+the last Brazilian beetle that he had added to his collection. Three\r
+young men in elaborate smoking-suits were handing tea-cakes to some of\r
+the women. The house-party consisted of twelve people, and there were\r
+more expected to arrive on the next day.\r
+\r
+"What are you two talking about?" said Lord Henry, strolling over to\r
+the table and putting his cup down. "I hope Dorian has told you about\r
+my plan for rechristening everything, Gladys. It is a delightful idea."\r
+\r
+"But I don't want to be rechristened, Harry," rejoined the duchess,\r
+looking up at him with her wonderful eyes. "I am quite satisfied with\r
+my own name, and I am sure Mr. Gray should be satisfied with his."\r
+\r
+"My dear Gladys, I would not alter either name for the world. They are\r
+both perfect. I was thinking chiefly of flowers. Yesterday I cut an\r
+orchid, for my button-hole. It was a marvellous spotted thing, as\r
+effective as the seven deadly sins. In a thoughtless moment I asked\r
+one of the gardeners what it was called. He told me it was a fine\r
+specimen of _Robinsoniana_, or something dreadful of that kind. It is a\r
+sad truth, but we have lost the faculty of giving lovely names to\r
+things. Names are everything. I never quarrel with actions. My one\r
+quarrel is with words. That is the reason I hate vulgar realism in\r
+literature. The man who could call a spade a spade should be compelled\r
+to use one. It is the only thing he is fit for."\r
+\r
+"Then what should we call you, Harry?" she asked.\r
+\r
+"His name is Prince Paradox," said Dorian.\r
+\r
+"I recognize him in a flash," exclaimed the duchess.\r
+\r
+"I won't hear of it," laughed Lord Henry, sinking into a chair. "From\r
+a label there is no escape! I refuse the title."\r
+\r
+"Royalties may not abdicate," fell as a warning from pretty lips.\r
+\r
+"You wish me to defend my throne, then?"\r
+\r
+"Yes."\r
+\r
+"I give the truths of to-morrow."\r
+\r
+"I prefer the mistakes of to-day," she answered.\r
+\r
+"You disarm me, Gladys," he cried, catching the wilfulness of her mood.\r
+\r
+"Of your shield, Harry, not of your spear."\r
+\r
+"I never tilt against beauty," he said, with a wave of his hand.\r
+\r
+"That is your error, Harry, believe me. You value beauty far too much."\r
+\r
+"How can you say that? I admit that I think that it is better to be\r
+beautiful than to be good. But on the other hand, no one is more ready\r
+than I am to acknowledge that it is better to be good than to be ugly."\r
+\r
+"Ugliness is one of the seven deadly sins, then?" cried the duchess.\r
+"What becomes of your simile about the orchid?"\r
+\r
+"Ugliness is one of the seven deadly virtues, Gladys. You, as a good\r
+Tory, must not underrate them. Beer, the Bible, and the seven deadly\r
+virtues have made our England what she is."\r
+\r
+"You don't like your country, then?" she asked.\r
+\r
+"I live in it."\r
+\r
+"That you may censure it the better."\r
+\r
+"Would you have me take the verdict of Europe on it?" he inquired.\r
+\r
+"What do they say of us?"\r
+\r
+"That Tartuffe has emigrated to England and opened a shop."\r
+\r
+"Is that yours, Harry?"\r
+\r
+"I give it to you."\r
+\r
+"I could not use it. It is too true."\r
+\r
+"You need not be afraid. Our countrymen never recognize a description."\r
+\r
+"They are practical."\r
+\r
+"They are more cunning than practical. When they make up their ledger,\r
+they balance stupidity by wealth, and vice by hypocrisy."\r
+\r
+"Still, we have done great things."\r
+\r
+"Great things have been thrust on us, Gladys."\r
+\r
+"We have carried their burden."\r
+\r
+"Only as far as the Stock Exchange."\r
+\r
+She shook her head. "I believe in the race," she cried.\r
+\r
+"It represents the survival of the pushing."\r
+\r
+"It has development."\r
+\r
+"Decay fascinates me more."\r
+\r
+"What of art?" she asked.\r
+\r
+"It is a malady."\r
+\r
+"Love?"\r
+\r
+"An illusion."\r
+\r
+"Religion?"\r
+\r
+"The fashionable substitute for belief."\r
+\r
+"You are a sceptic."\r
+\r
+"Never! Scepticism is the beginning of faith."\r
+\r
+"What are you?"\r
+\r
+"To define is to limit."\r
+\r
+"Give me a clue."\r
+\r
+"Threads snap. You would lose your way in the labyrinth."\r
+\r
+"You bewilder me. Let us talk of some one else."\r
+\r
+"Our host is a delightful topic. Years ago he was christened Prince\r
+Charming."\r
+\r
+"Ah! don't remind me of that," cried Dorian Gray.\r
+\r
+"Our host is rather horrid this evening," answered the duchess,\r
+colouring. "I believe he thinks that Monmouth married me on purely\r
+scientific principles as the best specimen he could find of a modern\r
+butterfly."\r
+\r
+"Well, I hope he won't stick pins into you, Duchess," laughed Dorian.\r
+\r
+"Oh! my maid does that already, Mr. Gray, when she is annoyed with me."\r
+\r
+"And what does she get annoyed with you about, Duchess?"\r
+\r
+"For the most trivial things, Mr. Gray, I assure you. Usually because\r
+I come in at ten minutes to nine and tell her that I must be dressed by\r
+half-past eight."\r
+\r
+"How unreasonable of her! You should give her warning."\r
+\r
+"I daren't, Mr. Gray. Why, she invents hats for me. You remember the\r
+one I wore at Lady Hilstone's garden-party? You don't, but it is nice\r
+of you to pretend that you do. Well, she made it out of nothing. All\r
+good hats are made out of nothing."\r
+\r
+"Like all good reputations, Gladys," interrupted Lord Henry. "Every\r
+effect that one produces gives one an enemy. To be popular one must be\r
+a mediocrity."\r
+\r
+"Not with women," said the duchess, shaking her head; "and women rule\r
+the world. I assure you we can't bear mediocrities. We women, as some\r
+one says, love with our ears, just as you men love with your eyes, if\r
+you ever love at all."\r
+\r
+"It seems to me that we never do anything else," murmured Dorian.\r
+\r
+"Ah! then, you never really love, Mr. Gray," answered the duchess with\r
+mock sadness.\r
+\r
+"My dear Gladys!" cried Lord Henry. "How can you say that? Romance\r
+lives by repetition, and repetition converts an appetite into an art.\r
+Besides, each time that one loves is the only time one has ever loved.\r
+Difference of object does not alter singleness of passion. It merely\r
+intensifies it. We can have in life but one great experience at best,\r
+and the secret of life is to reproduce that experience as often as\r
+possible."\r
+\r
+"Even when one has been wounded by it, Harry?" asked the duchess after\r
+a pause.\r
+\r
+"Especially when one has been wounded by it," answered Lord Henry.\r
+\r
+The duchess turned and looked at Dorian Gray with a curious expression\r
+in her eyes. "What do you say to that, Mr. Gray?" she inquired.\r
+\r
+Dorian hesitated for a moment. Then he threw his head back and\r
+laughed. "I always agree with Harry, Duchess."\r
+\r
+"Even when he is wrong?"\r
+\r
+"Harry is never wrong, Duchess."\r
+\r
+"And does his philosophy make you happy?"\r
+\r
+"I have never searched for happiness. Who wants happiness? I have\r
+searched for pleasure."\r
+\r
+"And found it, Mr. Gray?"\r
+\r
+"Often. Too often."\r
+\r
+The duchess sighed. "I am searching for peace," she said, "and if I\r
+don't go and dress, I shall have none this evening."\r
+\r
+"Let me get you some orchids, Duchess," cried Dorian, starting to his\r
+feet and walking down the conservatory.\r
+\r
+"You are flirting disgracefully with him," said Lord Henry to his\r
+cousin. "You had better take care. He is very fascinating."\r
+\r
+"If he were not, there would be no battle."\r
+\r
+"Greek meets Greek, then?"\r
+\r
+"I am on the side of the Trojans. They fought for a woman."\r
+\r
+"They were defeated."\r
+\r
+"There are worse things than capture," she answered.\r
+\r
+"You gallop with a loose rein."\r
+\r
+"Pace gives life," was the _riposte_.\r
+\r
+"I shall write it in my diary to-night."\r
+\r
+"What?"\r
+\r
+"That a burnt child loves the fire."\r
+\r
+"I am not even singed. My wings are untouched."\r
+\r
+"You use them for everything, except flight."\r
+\r
+"Courage has passed from men to women. It is a new experience for us."\r
+\r
+"You have a rival."\r
+\r
+"Who?"\r
+\r
+He laughed. "Lady Narborough," he whispered. "She perfectly adores\r
+him."\r
+\r
+"You fill me with apprehension. The appeal to antiquity is fatal to us\r
+who are romanticists."\r
+\r
+"Romanticists! You have all the methods of science."\r
+\r
+"Men have educated us."\r
+\r
+"But not explained you."\r
+\r
+"Describe us as a sex," was her challenge.\r
+\r
+"Sphinxes without secrets."\r
+\r
+She looked at him, smiling. "How long Mr. Gray is!" she said. "Let us\r
+go and help him. I have not yet told him the colour of my frock."\r
+\r
+"Ah! you must suit your frock to his flowers, Gladys."\r
+\r
+"That would be a premature surrender."\r
+\r
+"Romantic art begins with its climax."\r
+\r
+"I must keep an opportunity for retreat."\r
+\r
+"In the Parthian manner?"\r
+\r
+"They found safety in the desert. I could not do that."\r
+\r
+"Women are not always allowed a choice," he answered, but hardly had he\r
+finished the sentence before from the far end of the conservatory came\r
+a stifled groan, followed by the dull sound of a heavy fall. Everybody\r
+started up. The duchess stood motionless in horror. And with fear in\r
+his eyes, Lord Henry rushed through the flapping palms to find Dorian\r
+Gray lying face downwards on the tiled floor in a deathlike swoon.\r
+\r
+He was carried at once into the blue drawing-room and laid upon one of\r
+the sofas. After a short time, he came to himself and looked round\r
+with a dazed expression.\r
+\r
+"What has happened?" he asked. "Oh! I remember. Am I safe here,\r
+Harry?" He began to tremble.\r
+\r
+"My dear Dorian," answered Lord Henry, "you merely fainted. That was\r
+all. You must have overtired yourself. You had better not come down\r
+to dinner. I will take your place."\r
+\r
+"No, I will come down," he said, struggling to his feet. "I would\r
+rather come down. I must not be alone."\r
+\r
+He went to his room and dressed. There was a wild recklessness of\r
+gaiety in his manner as he sat at table, but now and then a thrill of\r
+terror ran through him when he remembered that, pressed against the\r
+window of the conservatory, like a white handkerchief, he had seen the\r
+face of James Vane watching him.\r
+\r
+\r
+\r
+CHAPTER 18\r
+\r
+The next day he did not leave the house, and, indeed, spent most of the\r
+time in his own room, sick with a wild terror of dying, and yet\r
+indifferent to life itself. The consciousness of being hunted, snared,\r
+tracked down, had begun to dominate him. If the tapestry did but\r
+tremble in the wind, he shook. The dead leaves that were blown against\r
+the leaded panes seemed to him like his own wasted resolutions and wild\r
+regrets. When he closed his eyes, he saw again the sailor's face\r
+peering through the mist-stained glass, and horror seemed once more to\r
+lay its hand upon his heart.\r
+\r
+But perhaps it had been only his fancy that had called vengeance out of\r
+the night and set the hideous shapes of punishment before him. Actual\r
+life was chaos, but there was something terribly logical in the\r
+imagination. It was the imagination that set remorse to dog the feet\r
+of sin. It was the imagination that made each crime bear its misshapen\r
+brood. In the common world of fact the wicked were not punished, nor\r
+the good rewarded. Success was given to the strong, failure thrust\r
+upon the weak. That was all. Besides, had any stranger been prowling\r
+round the house, he would have been seen by the servants or the\r
+keepers. Had any foot-marks been found on the flower-beds, the\r
+gardeners would have reported it. Yes, it had been merely fancy.\r
+Sibyl Vane's brother had not come back to kill him. He had sailed away\r
+in his ship to founder in some winter sea. From him, at any rate, he\r
+was safe. Why, the man did not know who he was, could not know who he\r
+was. The mask of youth had saved him.\r
+\r
+And yet if it had been merely an illusion, how terrible it was to think\r
+that conscience could raise such fearful phantoms, and give them\r
+visible form, and make them move before one! What sort of life would\r
+his be if, day and night, shadows of his crime were to peer at him from\r
+silent corners, to mock him from secret places, to whisper in his ear\r
+as he sat at the feast, to wake him with icy fingers as he lay asleep!\r
+As the thought crept through his brain, he grew pale with terror, and\r
+the air seemed to him to have become suddenly colder. Oh! in what a\r
+wild hour of madness he had killed his friend! How ghastly the mere\r
+memory of the scene! He saw it all again. Each hideous detail came\r
+back to him with added horror. Out of the black cave of time, terrible\r
+and swathed in scarlet, rose the image of his sin. When Lord Henry\r
+came in at six o'clock, he found him crying as one whose heart will\r
+break.\r
+\r
+It was not till the third day that he ventured to go out. There was\r
+something in the clear, pine-scented air of that winter morning that\r
+seemed to bring him back his joyousness and his ardour for life. But\r
+it was not merely the physical conditions of environment that had\r
+caused the change. His own nature had revolted against the excess of\r
+anguish that had sought to maim and mar the perfection of its calm.\r
+With subtle and finely wrought temperaments it is always so. Their\r
+strong passions must either bruise or bend. They either slay the man,\r
+or themselves die. Shallow sorrows and shallow loves live on. The\r
+loves and sorrows that are great are destroyed by their own plenitude.\r
+Besides, he had convinced himself that he had been the victim of a\r
+terror-stricken imagination, and looked back now on his fears with\r
+something of pity and not a little of contempt.\r
+\r
+After breakfast, he walked with the duchess for an hour in the garden\r
+and then drove across the park to join the shooting-party. The crisp\r
+frost lay like salt upon the grass. The sky was an inverted cup of\r
+blue metal. A thin film of ice bordered the flat, reed-grown lake.\r
+\r
+At the corner of the pine-wood he caught sight of Sir Geoffrey\r
+Clouston, the duchess's brother, jerking two spent cartridges out of\r
+his gun. He jumped from the cart, and having told the groom to take\r
+the mare home, made his way towards his guest through the withered\r
+bracken and rough undergrowth.\r
+\r
+"Have you had good sport, Geoffrey?" he asked.\r
+\r
+"Not very good, Dorian. I think most of the birds have gone to the\r
+open. I dare say it will be better after lunch, when we get to new\r
+ground."\r
+\r
+Dorian strolled along by his side. The keen aromatic air, the brown\r
+and red lights that glimmered in the wood, the hoarse cries of the\r
+beaters ringing out from time to time, and the sharp snaps of the guns\r
+that followed, fascinated him and filled him with a sense of delightful\r
+freedom. He was dominated by the carelessness of happiness, by the\r
+high indifference of joy.\r
+\r
+Suddenly from a lumpy tussock of old grass some twenty yards in front\r
+of them, with black-tipped ears erect and long hinder limbs throwing it\r
+forward, started a hare. It bolted for a thicket of alders. Sir\r
+Geoffrey put his gun to his shoulder, but there was something in the\r
+animal's grace of movement that strangely charmed Dorian Gray, and he\r
+cried out at once, "Don't shoot it, Geoffrey. Let it live."\r
+\r
+"What nonsense, Dorian!" laughed his companion, and as the hare bounded\r
+into the thicket, he fired. There were two cries heard, the cry of a\r
+hare in pain, which is dreadful, the cry of a man in agony, which is\r
+worse.\r
+\r
+"Good heavens! I have hit a beater!" exclaimed Sir Geoffrey. "What an\r
+ass the man was to get in front of the guns! Stop shooting there!" he\r
+called out at the top of his voice. "A man is hurt."\r
+\r
+The head-keeper came running up with a stick in his hand.\r
+\r
+"Where, sir? Where is he?" he shouted. At the same time, the firing\r
+ceased along the line.\r
+\r
+"Here," answered Sir Geoffrey angrily, hurrying towards the thicket.\r
+"Why on earth don't you keep your men back? Spoiled my shooting for\r
+the day."\r
+\r
+Dorian watched them as they plunged into the alder-clump, brushing the\r
+lithe swinging branches aside. In a few moments they emerged, dragging\r
+a body after them into the sunlight. He turned away in horror. It\r
+seemed to him that misfortune followed wherever he went. He heard Sir\r
+Geoffrey ask if the man was really dead, and the affirmative answer of\r
+the keeper. The wood seemed to him to have become suddenly alive with\r
+faces. There was the trampling of myriad feet and the low buzz of\r
+voices. A great copper-breasted pheasant came beating through the\r
+boughs overhead.\r
+\r
+After a few moments--that were to him, in his perturbed state, like\r
+endless hours of pain--he felt a hand laid on his shoulder. He started\r
+and looked round.\r
+\r
+"Dorian," said Lord Henry, "I had better tell them that the shooting is\r
+stopped for to-day. It would not look well to go on."\r
+\r
+"I wish it were stopped for ever, Harry," he answered bitterly. "The\r
+whole thing is hideous and cruel. Is the man ...?"\r
+\r
+He could not finish the sentence.\r
+\r
+"I am afraid so," rejoined Lord Henry. "He got the whole charge of\r
+shot in his chest. He must have died almost instantaneously. Come;\r
+let us go home."\r
+\r
+They walked side by side in the direction of the avenue for nearly\r
+fifty yards without speaking. Then Dorian looked at Lord Henry and\r
+said, with a heavy sigh, "It is a bad omen, Harry, a very bad omen."\r
+\r
+"What is?" asked Lord Henry. "Oh! this accident, I suppose. My dear\r
+fellow, it can't be helped. It was the man's own fault. Why did he\r
+get in front of the guns? Besides, it is nothing to us. It is rather\r
+awkward for Geoffrey, of course. It does not do to pepper beaters. It\r
+makes people think that one is a wild shot. And Geoffrey is not; he\r
+shoots very straight. But there is no use talking about the matter."\r
+\r
+Dorian shook his head. "It is a bad omen, Harry. I feel as if\r
+something horrible were going to happen to some of us. To myself,\r
+perhaps," he added, passing his hand over his eyes, with a gesture of\r
+pain.\r
+\r
+The elder man laughed. "The only horrible thing in the world is _ennui_,\r
+Dorian. That is the one sin for which there is no forgiveness. But we\r
+are not likely to suffer from it unless these fellows keep chattering\r
+about this thing at dinner. I must tell them that the subject is to be\r
+tabooed. As for omens, there is no such thing as an omen. Destiny\r
+does not send us heralds. She is too wise or too cruel for that.\r
+Besides, what on earth could happen to you, Dorian? You have\r
+everything in the world that a man can want. There is no one who would\r
+not be delighted to change places with you."\r
+\r
+"There is no one with whom I would not change places, Harry. Don't\r
+laugh like that. I am telling you the truth. The wretched peasant who\r
+has just died is better off than I am. I have no terror of death. It\r
+is the coming of death that terrifies me. Its monstrous wings seem to\r
+wheel in the leaden air around me. Good heavens! don't you see a man\r
+moving behind the trees there, watching me, waiting for me?"\r
+\r
+Lord Henry looked in the direction in which the trembling gloved hand\r
+was pointing. "Yes," he said, smiling, "I see the gardener waiting for\r
+you. I suppose he wants to ask you what flowers you wish to have on\r
+the table to-night. How absurdly nervous you are, my dear fellow! You\r
+must come and see my doctor, when we get back to town."\r
+\r
+Dorian heaved a sigh of relief as he saw the gardener approaching. The\r
+man touched his hat, glanced for a moment at Lord Henry in a hesitating\r
+manner, and then produced a letter, which he handed to his master.\r
+"Her Grace told me to wait for an answer," he murmured.\r
+\r
+Dorian put the letter into his pocket. "Tell her Grace that I am\r
+coming in," he said, coldly. The man turned round and went rapidly in\r
+the direction of the house.\r
+\r
+"How fond women are of doing dangerous things!" laughed Lord Henry.\r
+"It is one of the qualities in them that I admire most. A woman will\r
+flirt with anybody in the world as long as other people are looking on."\r
+\r
+"How fond you are of saying dangerous things, Harry! In the present\r
+instance, you are quite astray. I like the duchess very much, but I\r
+don't love her."\r
+\r
+"And the duchess loves you very much, but she likes you less, so you\r
+are excellently matched."\r
+\r
+"You are talking scandal, Harry, and there is never any basis for\r
+scandal."\r
+\r
+"The basis of every scandal is an immoral certainty," said Lord Henry,\r
+lighting a cigarette.\r
+\r
+"You would sacrifice anybody, Harry, for the sake of an epigram."\r
+\r
+"The world goes to the altar of its own accord," was the answer.\r
+\r
+"I wish I could love," cried Dorian Gray with a deep note of pathos in\r
+his voice. "But I seem to have lost the passion and forgotten the\r
+desire. I am too much concentrated on myself. My own personality has\r
+become a burden to me. I want to escape, to go away, to forget. It\r
+was silly of me to come down here at all. I think I shall send a wire\r
+to Harvey to have the yacht got ready. On a yacht one is safe."\r
+\r
+"Safe from what, Dorian? You are in some trouble. Why not tell me\r
+what it is? You know I would help you."\r
+\r
+"I can't tell you, Harry," he answered sadly. "And I dare say it is\r
+only a fancy of mine. This unfortunate accident has upset me. I have\r
+a horrible presentiment that something of the kind may happen to me."\r
+\r
+"What nonsense!"\r
+\r
+"I hope it is, but I can't help feeling it. Ah! here is the duchess,\r
+looking like Artemis in a tailor-made gown. You see we have come back,\r
+Duchess."\r
+\r
+"I have heard all about it, Mr. Gray," she answered. "Poor Geoffrey is\r
+terribly upset. And it seems that you asked him not to shoot the hare.\r
+How curious!"\r
+\r
+"Yes, it was very curious. I don't know what made me say it. Some\r
+whim, I suppose. It looked the loveliest of little live things. But I\r
+am sorry they told you about the man. It is a hideous subject."\r
+\r
+"It is an annoying subject," broke in Lord Henry. "It has no\r
+psychological value at all. Now if Geoffrey had done the thing on\r
+purpose, how interesting he would be! I should like to know some one\r
+who had committed a real murder."\r
+\r
+"How horrid of you, Harry!" cried the duchess. "Isn't it, Mr. Gray?\r
+Harry, Mr. Gray is ill again. He is going to faint."\r
+\r
+Dorian drew himself up with an effort and smiled. "It is nothing,\r
+Duchess," he murmured; "my nerves are dreadfully out of order. That is\r
+all. I am afraid I walked too far this morning. I didn't hear what\r
+Harry said. Was it very bad? You must tell me some other time. I\r
+think I must go and lie down. You will excuse me, won't you?"\r
+\r
+They had reached the great flight of steps that led from the\r
+conservatory on to the terrace. As the glass door closed behind\r
+Dorian, Lord Henry turned and looked at the duchess with his slumberous\r
+eyes. "Are you very much in love with him?" he asked.\r
+\r
+She did not answer for some time, but stood gazing at the landscape.\r
+"I wish I knew," she said at last.\r
+\r
+He shook his head. "Knowledge would be fatal. It is the uncertainty\r
+that charms one. A mist makes things wonderful."\r
+\r
+"One may lose one's way."\r
+\r
+"All ways end at the same point, my dear Gladys."\r
+\r
+"What is that?"\r
+\r
+"Disillusion."\r
+\r
+"It was my _debut_ in life," she sighed.\r
+\r
+"It came to you crowned."\r
+\r
+"I am tired of strawberry leaves."\r
+\r
+"They become you."\r
+\r
+"Only in public."\r
+\r
+"You would miss them," said Lord Henry.\r
+\r
+"I will not part with a petal."\r
+\r
+"Monmouth has ears."\r
+\r
+"Old age is dull of hearing."\r
+\r
+"Has he never been jealous?"\r
+\r
+"I wish he had been."\r
+\r
+He glanced about as if in search of something. "What are you looking\r
+for?" she inquired.\r
+\r
+"The button from your foil," he answered. "You have dropped it."\r
+\r
+She laughed. "I have still the mask."\r
+\r
+"It makes your eyes lovelier," was his reply.\r
+\r
+She laughed again. Her teeth showed like white seeds in a scarlet\r
+fruit.\r
+\r
+Upstairs, in his own room, Dorian Gray was lying on a sofa, with terror\r
+in every tingling fibre of his body. Life had suddenly become too\r
+hideous a burden for him to bear. The dreadful death of the unlucky\r
+beater, shot in the thicket like a wild animal, had seemed to him to\r
+pre-figure death for himself also. He had nearly swooned at what Lord\r
+Henry had said in a chance mood of cynical jesting.\r
+\r
+At five o'clock he rang his bell for his servant and gave him orders to\r
+pack his things for the night-express to town, and to have the brougham\r
+at the door by eight-thirty. He was determined not to sleep another\r
+night at Selby Royal. It was an ill-omened place. Death walked there\r
+in the sunlight. The grass of the forest had been spotted with blood.\r
+\r
+Then he wrote a note to Lord Henry, telling him that he was going up to\r
+town to consult his doctor and asking him to entertain his guests in\r
+his absence. As he was putting it into the envelope, a knock came to\r
+the door, and his valet informed him that the head-keeper wished to see\r
+him. He frowned and bit his lip. "Send him in," he muttered, after\r
+some moments' hesitation.\r
+\r
+As soon as the man entered, Dorian pulled his chequebook out of a\r
+drawer and spread it out before him.\r
+\r
+"I suppose you have come about the unfortunate accident of this\r
+morning, Thornton?" he said, taking up a pen.\r
+\r
+"Yes, sir," answered the gamekeeper.\r
+\r
+"Was the poor fellow married? Had he any people dependent on him?"\r
+asked Dorian, looking bored. "If so, I should not like them to be left\r
+in want, and will send them any sum of money you may think necessary."\r
+\r
+"We don't know who he is, sir. That is what I took the liberty of\r
+coming to you about."\r
+\r
+"Don't know who he is?" said Dorian, listlessly. "What do you mean?\r
+Wasn't he one of your men?"\r
+\r
+"No, sir. Never saw him before. Seems like a sailor, sir."\r
+\r
+The pen dropped from Dorian Gray's hand, and he felt as if his heart\r
+had suddenly stopped beating. "A sailor?" he cried out. "Did you say\r
+a sailor?"\r
+\r
+"Yes, sir. He looks as if he had been a sort of sailor; tattooed on\r
+both arms, and that kind of thing."\r
+\r
+"Was there anything found on him?" said Dorian, leaning forward and\r
+looking at the man with startled eyes. "Anything that would tell his\r
+name?"\r
+\r
+"Some money, sir--not much, and a six-shooter. There was no name of any\r
+kind. A decent-looking man, sir, but rough-like. A sort of sailor we\r
+think."\r
+\r
+Dorian started to his feet. A terrible hope fluttered past him. He\r
+clutched at it madly. "Where is the body?" he exclaimed. "Quick! I\r
+must see it at once."\r
+\r
+"It is in an empty stable in the Home Farm, sir. The folk don't like\r
+to have that sort of thing in their houses. They say a corpse brings\r
+bad luck."\r
+\r
+"The Home Farm! Go there at once and meet me. Tell one of the grooms\r
+to bring my horse round. No. Never mind. I'll go to the stables\r
+myself. It will save time."\r
+\r
+In less than a quarter of an hour, Dorian Gray was galloping down the\r
+long avenue as hard as he could go. The trees seemed to sweep past him\r
+in spectral procession, and wild shadows to fling themselves across his\r
+path. Once the mare swerved at a white gate-post and nearly threw him.\r
+He lashed her across the neck with his crop. She cleft the dusky air\r
+like an arrow. The stones flew from her hoofs.\r
+\r
+At last he reached the Home Farm. Two men were loitering in the yard.\r
+He leaped from the saddle and threw the reins to one of them. In the\r
+farthest stable a light was glimmering. Something seemed to tell him\r
+that the body was there, and he hurried to the door and put his hand\r
+upon the latch.\r
+\r
+There he paused for a moment, feeling that he was on the brink of a\r
+discovery that would either make or mar his life. Then he thrust the\r
+door open and entered.\r
+\r
+On a heap of sacking in the far corner was lying the dead body of a man\r
+dressed in a coarse shirt and a pair of blue trousers. A spotted\r
+handkerchief had been placed over the face. A coarse candle, stuck in\r
+a bottle, sputtered beside it.\r
+\r
+Dorian Gray shuddered. He felt that his could not be the hand to take\r
+the handkerchief away, and called out to one of the farm-servants to\r
+come to him.\r
+\r
+"Take that thing off the face. I wish to see it," he said, clutching\r
+at the door-post for support.\r
+\r
+When the farm-servant had done so, he stepped forward. A cry of joy\r
+broke from his lips. The man who had been shot in the thicket was\r
+James Vane.\r
+\r
+He stood there for some minutes looking at the dead body. As he rode\r
+home, his eyes were full of tears, for he knew he was safe.\r
+\r
+\r
+\r
+CHAPTER 19\r
+\r
+"There is no use your telling me that you are going to be good," cried\r
+Lord Henry, dipping his white fingers into a red copper bowl filled\r
+with rose-water. "You are quite perfect. Pray, don't change."\r
+\r
+Dorian Gray shook his head. "No, Harry, I have done too many dreadful\r
+things in my life. I am not going to do any more. I began my good\r
+actions yesterday."\r
+\r
+"Where were you yesterday?"\r
+\r
+"In the country, Harry. I was staying at a little inn by myself."\r
+\r
+"My dear boy," said Lord Henry, smiling, "anybody can be good in the\r
+country. There are no temptations there. That is the reason why\r
+people who live out of town are so absolutely uncivilized.\r
+Civilization is not by any means an easy thing to attain to. There are\r
+only two ways by which man can reach it. One is by being cultured, the\r
+other by being corrupt. Country people have no opportunity of being\r
+either, so they stagnate."\r
+\r
+"Culture and corruption," echoed Dorian. "I have known something of\r
+both. It seems terrible to me now that they should ever be found\r
+together. For I have a new ideal, Harry. I am going to alter. I\r
+think I have altered."\r
+\r
+"You have not yet told me what your good action was. Or did you say\r
+you had done more than one?" asked his companion as he spilled into his\r
+plate a little crimson pyramid of seeded strawberries and, through a\r
+perforated, shell-shaped spoon, snowed white sugar upon them.\r
+\r
+"I can tell you, Harry. It is not a story I could tell to any one\r
+else. I spared somebody. It sounds vain, but you understand what I\r
+mean. She was quite beautiful and wonderfully like Sibyl Vane. I\r
+think it was that which first attracted me to her. You remember Sibyl,\r
+don't you? How long ago that seems! Well, Hetty was not one of our\r
+own class, of course. She was simply a girl in a village. But I\r
+really loved her. I am quite sure that I loved her. All during this\r
+wonderful May that we have been having, I used to run down and see her\r
+two or three times a week. Yesterday she met me in a little orchard.\r
+The apple-blossoms kept tumbling down on her hair, and she was\r
+laughing. We were to have gone away together this morning at dawn.\r
+Suddenly I determined to leave her as flowerlike as I had found her."\r
+\r
+"I should think the novelty of the emotion must have given you a thrill\r
+of real pleasure, Dorian," interrupted Lord Henry. "But I can finish\r
+your idyll for you. You gave her good advice and broke her heart.\r
+That was the beginning of your reformation."\r
+\r
+"Harry, you are horrible! You mustn't say these dreadful things.\r
+Hetty's heart is not broken. Of course, she cried and all that. But\r
+there is no disgrace upon her. She can live, like Perdita, in her\r
+garden of mint and marigold."\r
+\r
+"And weep over a faithless Florizel," said Lord Henry, laughing, as he\r
+leaned back in his chair. "My dear Dorian, you have the most curiously\r
+boyish moods. Do you think this girl will ever be really content now\r
+with any one of her own rank? I suppose she will be married some day\r
+to a rough carter or a grinning ploughman. Well, the fact of having\r
+met you, and loved you, will teach her to despise her husband, and she\r
+will be wretched. From a moral point of view, I cannot say that I\r
+think much of your great renunciation. Even as a beginning, it is\r
+poor. Besides, how do you know that Hetty isn't floating at the\r
+present moment in some starlit mill-pond, with lovely water-lilies\r
+round her, like Ophelia?"\r
+\r
+"I can't bear this, Harry! You mock at everything, and then suggest\r
+the most serious tragedies. I am sorry I told you now. I don't care\r
+what you say to me. I know I was right in acting as I did. Poor\r
+Hetty! As I rode past the farm this morning, I saw her white face at\r
+the window, like a spray of jasmine. Don't let us talk about it any\r
+more, and don't try to persuade me that the first good action I have\r
+done for years, the first little bit of self-sacrifice I have ever\r
+known, is really a sort of sin. I want to be better. I am going to be\r
+better. Tell me something about yourself. What is going on in town?\r
+I have not been to the club for days."\r
+\r
+"The people are still discussing poor Basil's disappearance."\r
+\r
+"I should have thought they had got tired of that by this time," said\r
+Dorian, pouring himself out some wine and frowning slightly.\r
+\r
+"My dear boy, they have only been talking about it for six weeks, and\r
+the British public are really not equal to the mental strain of having\r
+more than one topic every three months. They have been very fortunate\r
+lately, however. They have had my own divorce-case and Alan Campbell's\r
+suicide. Now they have got the mysterious disappearance of an artist.\r
+Scotland Yard still insists that the man in the grey ulster who left\r
+for Paris by the midnight train on the ninth of November was poor\r
+Basil, and the French police declare that Basil never arrived in Paris\r
+at all. I suppose in about a fortnight we shall be told that he has\r
+been seen in San Francisco. It is an odd thing, but every one who\r
+disappears is said to be seen at San Francisco. It must be a\r
+delightful city, and possess all the attractions of the next world."\r
+\r
+"What do you think has happened to Basil?" asked Dorian, holding up his\r
+Burgundy against the light and wondering how it was that he could\r
+discuss the matter so calmly.\r
+\r
+"I have not the slightest idea. If Basil chooses to hide himself, it\r
+is no business of mine. If he is dead, I don't want to think about\r
+him. Death is the only thing that ever terrifies me. I hate it."\r
+\r
+"Why?" said the younger man wearily.\r
+\r
+"Because," said Lord Henry, passing beneath his nostrils the gilt\r
+trellis of an open vinaigrette box, "one can survive everything\r
+nowadays except that. Death and vulgarity are the only two facts in\r
+the nineteenth century that one cannot explain away. Let us have our\r
+coffee in the music-room, Dorian. You must play Chopin to me. The man\r
+with whom my wife ran away played Chopin exquisitely. Poor Victoria!\r
+I was very fond of her. The house is rather lonely without her. Of\r
+course, married life is merely a habit, a bad habit. But then one\r
+regrets the loss even of one's worst habits. Perhaps one regrets them\r
+the most. They are such an essential part of one's personality."\r
+\r
+Dorian said nothing, but rose from the table, and passing into the next\r
+room, sat down to the piano and let his fingers stray across the white\r
+and black ivory of the keys. After the coffee had been brought in, he\r
+stopped, and looking over at Lord Henry, said, "Harry, did it ever\r
+occur to you that Basil was murdered?"\r
+\r
+Lord Henry yawned. "Basil was very popular, and always wore a\r
+Waterbury watch. Why should he have been murdered? He was not clever\r
+enough to have enemies. Of course, he had a wonderful genius for\r
+painting. But a man can paint like Velasquez and yet be as dull as\r
+possible. Basil was really rather dull. He only interested me once,\r
+and that was when he told me, years ago, that he had a wild adoration\r
+for you and that you were the dominant motive of his art."\r
+\r
+"I was very fond of Basil," said Dorian with a note of sadness in his\r
+voice. "But don't people say that he was murdered?"\r
+\r
+"Oh, some of the papers do. It does not seem to me to be at all\r
+probable. I know there are dreadful places in Paris, but Basil was not\r
+the sort of man to have gone to them. He had no curiosity. It was his\r
+chief defect."\r
+\r
+"What would you say, Harry, if I told you that I had murdered Basil?"\r
+said the younger man. He watched him intently after he had spoken.\r
+\r
+"I would say, my dear fellow, that you were posing for a character that\r
+doesn't suit you. All crime is vulgar, just as all vulgarity is crime.\r
+It is not in you, Dorian, to commit a murder. I am sorry if I hurt\r
+your vanity by saying so, but I assure you it is true. Crime belongs\r
+exclusively to the lower orders. I don't blame them in the smallest\r
+degree. I should fancy that crime was to them what art is to us,\r
+simply a method of procuring extraordinary sensations."\r
+\r
+"A method of procuring sensations? Do you think, then, that a man who\r
+has once committed a murder could possibly do the same crime again?\r
+Don't tell me that."\r
+\r
+"Oh! anything becomes a pleasure if one does it too often," cried Lord\r
+Henry, laughing. "That is one of the most important secrets of life.\r
+I should fancy, however, that murder is always a mistake. One should\r
+never do anything that one cannot talk about after dinner. But let us\r
+pass from poor Basil. I wish I could believe that he had come to such\r
+a really romantic end as you suggest, but I can't. I dare say he fell\r
+into the Seine off an omnibus and that the conductor hushed up the\r
+scandal. Yes: I should fancy that was his end. I see him lying now\r
+on his back under those dull-green waters, with the heavy barges\r
+floating over him and long weeds catching in his hair. Do you know, I\r
+don't think he would have done much more good work. During the last\r
+ten years his painting had gone off very much."\r
+\r
+Dorian heaved a sigh, and Lord Henry strolled across the room and began\r
+to stroke the head of a curious Java parrot, a large, grey-plumaged\r
+bird with pink crest and tail, that was balancing itself upon a bamboo\r
+perch. As his pointed fingers touched it, it dropped the white scurf\r
+of crinkled lids over black, glasslike eyes and began to sway backwards\r
+and forwards.\r
+\r
+"Yes," he continued, turning round and taking his handkerchief out of\r
+his pocket; "his painting had quite gone off. It seemed to me to have\r
+lost something. It had lost an ideal. When you and he ceased to be\r
+great friends, he ceased to be a great artist. What was it separated\r
+you? I suppose he bored you. If so, he never forgave you. It's a\r
+habit bores have. By the way, what has become of that wonderful\r
+portrait he did of you? I don't think I have ever seen it since he\r
+finished it. Oh! I remember your telling me years ago that you had\r
+sent it down to Selby, and that it had got mislaid or stolen on the\r
+way. You never got it back? What a pity! it was really a\r
+masterpiece. I remember I wanted to buy it. I wish I had now. It\r
+belonged to Basil's best period. Since then, his work was that curious\r
+mixture of bad painting and good intentions that always entitles a man\r
+to be called a representative British artist. Did you advertise for\r
+it? You should."\r
+\r
+"I forget," said Dorian. "I suppose I did. But I never really liked\r
+it. I am sorry I sat for it. The memory of the thing is hateful to\r
+me. Why do you talk of it? It used to remind me of those curious\r
+lines in some play--Hamlet, I think--how do they run?--\r
+\r
+ "Like the painting of a sorrow,\r
+ A face without a heart."\r
+\r
+Yes: that is what it was like."\r
+\r
+Lord Henry laughed. "If a man treats life artistically, his brain is\r
+his heart," he answered, sinking into an arm-chair.\r
+\r
+Dorian Gray shook his head and struck some soft chords on the piano.\r
+"'Like the painting of a sorrow,'" he repeated, "'a face without a\r
+heart.'"\r
+\r
+The elder man lay back and looked at him with half-closed eyes. "By\r
+the way, Dorian," he said after a pause, "'what does it profit a man if\r
+he gain the whole world and lose--how does the quotation run?--his own\r
+soul'?"\r
+\r
+The music jarred, and Dorian Gray started and stared at his friend.\r
+"Why do you ask me that, Harry?"\r
+\r
+"My dear fellow," said Lord Henry, elevating his eyebrows in surprise,\r
+"I asked you because I thought you might be able to give me an answer.\r
+That is all. I was going through the park last Sunday, and close by\r
+the Marble Arch there stood a little crowd of shabby-looking people\r
+listening to some vulgar street-preacher. As I passed by, I heard the\r
+man yelling out that question to his audience. It struck me as being\r
+rather dramatic. London is very rich in curious effects of that kind.\r
+A wet Sunday, an uncouth Christian in a mackintosh, a ring of sickly\r
+white faces under a broken roof of dripping umbrellas, and a wonderful\r
+phrase flung into the air by shrill hysterical lips--it was really very\r
+good in its way, quite a suggestion. I thought of telling the prophet\r
+that art had a soul, but that man had not. I am afraid, however, he\r
+would not have understood me."\r
+\r
+"Don't, Harry. The soul is a terrible reality. It can be bought, and\r
+sold, and bartered away. It can be poisoned, or made perfect. There\r
+is a soul in each one of us. I know it."\r
+\r
+"Do you feel quite sure of that, Dorian?"\r
+\r
+"Quite sure."\r
+\r
+"Ah! then it must be an illusion. The things one feels absolutely\r
+certain about are never true. That is the fatality of faith, and the\r
+lesson of romance. How grave you are! Don't be so serious. What have\r
+you or I to do with the superstitions of our age? No: we have given\r
+up our belief in the soul. Play me something. Play me a nocturne,\r
+Dorian, and, as you play, tell me, in a low voice, how you have kept\r
+your youth. You must have some secret. I am only ten years older than\r
+you are, and I am wrinkled, and worn, and yellow. You are really\r
+wonderful, Dorian. You have never looked more charming than you do\r
+to-night. You remind me of the day I saw you first. You were rather\r
+cheeky, very shy, and absolutely extraordinary. You have changed, of\r
+course, but not in appearance. I wish you would tell me your secret.\r
+To get back my youth I would do anything in the world, except take\r
+exercise, get up early, or be respectable. Youth! There is nothing\r
+like it. It's absurd to talk of the ignorance of youth. The only\r
+people to whose opinions I listen now with any respect are people much\r
+younger than myself. They seem in front of me. Life has revealed to\r
+them her latest wonder. As for the aged, I always contradict the aged.\r
+I do it on principle. If you ask them their opinion on something that\r
+happened yesterday, they solemnly give you the opinions current in\r
+1820, when people wore high stocks, believed in everything, and knew\r
+absolutely nothing. How lovely that thing you are playing is! I\r
+wonder, did Chopin write it at Majorca, with the sea weeping round the\r
+villa and the salt spray dashing against the panes? It is marvellously\r
+romantic. What a blessing it is that there is one art left to us that\r
+is not imitative! Don't stop. I want music to-night. It seems to me\r
+that you are the young Apollo and that I am Marsyas listening to you.\r
+I have sorrows, Dorian, of my own, that even you know nothing of. The\r
+tragedy of old age is not that one is old, but that one is young. I am\r
+amazed sometimes at my own sincerity. Ah, Dorian, how happy you are!\r
+What an exquisite life you have had! You have drunk deeply of\r
+everything. You have crushed the grapes against your palate. Nothing\r
+has been hidden from you. And it has all been to you no more than the\r
+sound of music. It has not marred you. You are still the same."\r
+\r
+"I am not the same, Harry."\r
+\r
+"Yes, you are the same. I wonder what the rest of your life will be.\r
+Don't spoil it by renunciations. At present you are a perfect type.\r
+Don't make yourself incomplete. You are quite flawless now. You need\r
+not shake your head: you know you are. Besides, Dorian, don't deceive\r
+yourself. Life is not governed by will or intention. Life is a\r
+question of nerves, and fibres, and slowly built-up cells in which\r
+thought hides itself and passion has its dreams. You may fancy\r
+yourself safe and think yourself strong. But a chance tone of colour\r
+in a room or a morning sky, a particular perfume that you had once\r
+loved and that brings subtle memories with it, a line from a forgotten\r
+poem that you had come across again, a cadence from a piece of music\r
+that you had ceased to play--I tell you, Dorian, that it is on things\r
+like these that our lives depend. Browning writes about that\r
+somewhere; but our own senses will imagine them for us. There are\r
+moments when the odour of _lilas blanc_ passes suddenly across me, and I\r
+have to live the strangest month of my life over again. I wish I could\r
+change places with you, Dorian. The world has cried out against us\r
+both, but it has always worshipped you. It always will worship you.\r
+You are the type of what the age is searching for, and what it is\r
+afraid it has found. I am so glad that you have never done anything,\r
+never carved a statue, or painted a picture, or produced anything\r
+outside of yourself! Life has been your art. You have set yourself to\r
+music. Your days are your sonnets."\r
+\r
+Dorian rose up from the piano and passed his hand through his hair.\r
+"Yes, life has been exquisite," he murmured, "but I am not going to\r
+have the same life, Harry. And you must not say these extravagant\r
+things to me. You don't know everything about me. I think that if you\r
+did, even you would turn from me. You laugh. Don't laugh."\r
+\r
+"Why have you stopped playing, Dorian? Go back and give me the\r
+nocturne over again. Look at that great, honey-coloured moon that\r
+hangs in the dusky air. She is waiting for you to charm her, and if\r
+you play she will come closer to the earth. You won't? Let us go to\r
+the club, then. It has been a charming evening, and we must end it\r
+charmingly. There is some one at White's who wants immensely to know\r
+you--young Lord Poole, Bournemouth's eldest son. He has already copied\r
+your neckties, and has begged me to introduce him to you. He is quite\r
+delightful and rather reminds me of you."\r
+\r
+"I hope not," said Dorian with a sad look in his eyes. "But I am tired\r
+to-night, Harry. I shan't go to the club. It is nearly eleven, and I\r
+want to go to bed early."\r
+\r
+"Do stay. You have never played so well as to-night. There was\r
+something in your touch that was wonderful. It had more expression\r
+than I had ever heard from it before."\r
+\r
+"It is because I am going to be good," he answered, smiling. "I am a\r
+little changed already."\r
+\r
+"You cannot change to me, Dorian," said Lord Henry. "You and I will\r
+always be friends."\r
+\r
+"Yet you poisoned me with a book once. I should not forgive that.\r
+Harry, promise me that you will never lend that book to any one. It\r
+does harm."\r
+\r
+"My dear boy, you are really beginning to moralize. You will soon be\r
+going about like the converted, and the revivalist, warning people\r
+against all the sins of which you have grown tired. You are much too\r
+delightful to do that. Besides, it is no use. You and I are what we\r
+are, and will be what we will be. As for being poisoned by a book,\r
+there is no such thing as that. Art has no influence upon action. It\r
+annihilates the desire to act. It is superbly sterile. The books that\r
+the world calls immoral are books that show the world its own shame.\r
+That is all. But we won't discuss literature. Come round to-morrow. I\r
+am going to ride at eleven. We might go together, and I will take you\r
+to lunch afterwards with Lady Branksome. She is a charming woman, and\r
+wants to consult you about some tapestries she is thinking of buying.\r
+Mind you come. Or shall we lunch with our little duchess? She says\r
+she never sees you now. Perhaps you are tired of Gladys? I thought\r
+you would be. Her clever tongue gets on one's nerves. Well, in any\r
+case, be here at eleven."\r
+\r
+"Must I really come, Harry?"\r
+\r
+"Certainly. The park is quite lovely now. I don't think there have\r
+been such lilacs since the year I met you."\r
+\r
+"Very well. I shall be here at eleven," said Dorian. "Good night,\r
+Harry." As he reached the door, he hesitated for a moment, as if he\r
+had something more to say. Then he sighed and went out.\r
+\r
+\r
+\r
+CHAPTER 20\r
+\r
+It was a lovely night, so warm that he threw his coat over his arm and\r
+did not even put his silk scarf round his throat. As he strolled home,\r
+smoking his cigarette, two young men in evening dress passed him. He\r
+heard one of them whisper to the other, "That is Dorian Gray." He\r
+remembered how pleased he used to be when he was pointed out, or stared\r
+at, or talked about. He was tired of hearing his own name now. Half\r
+the charm of the little village where he had been so often lately was\r
+that no one knew who he was. He had often told the girl whom he had\r
+lured to love him that he was poor, and she had believed him. He had\r
+told her once that he was wicked, and she had laughed at him and\r
+answered that wicked people were always very old and very ugly. What a\r
+laugh she had!--just like a thrush singing. And how pretty she had\r
+been in her cotton dresses and her large hats! She knew nothing, but\r
+she had everything that he had lost.\r
+\r
+When he reached home, he found his servant waiting up for him. He sent\r
+him to bed, and threw himself down on the sofa in the library, and\r
+began to think over some of the things that Lord Henry had said to him.\r
+\r
+Was it really true that one could never change? He felt a wild longing\r
+for the unstained purity of his boyhood--his rose-white boyhood, as\r
+Lord Henry had once called it. He knew that he had tarnished himself,\r
+filled his mind with corruption and given horror to his fancy; that he\r
+had been an evil influence to others, and had experienced a terrible\r
+joy in being so; and that of the lives that had crossed his own, it had\r
+been the fairest and the most full of promise that he had brought to\r
+shame. But was it all irretrievable? Was there no hope for him?\r
+\r
+Ah! in what a monstrous moment of pride and passion he had prayed that\r
+the portrait should bear the burden of his days, and he keep the\r
+unsullied splendour of eternal youth! All his failure had been due to\r
+that. Better for him that each sin of his life had brought its sure\r
+swift penalty along with it. There was purification in punishment.\r
+Not "Forgive us our sins" but "Smite us for our iniquities" should be\r
+the prayer of man to a most just God.\r
+\r
+The curiously carved mirror that Lord Henry had given to him, so many\r
+years ago now, was standing on the table, and the white-limbed Cupids\r
+laughed round it as of old. He took it up, as he had done on that\r
+night of horror when he had first noted the change in the fatal\r
+picture, and with wild, tear-dimmed eyes looked into its polished\r
+shield. Once, some one who had terribly loved him had written to him a\r
+mad letter, ending with these idolatrous words: "The world is changed\r
+because you are made of ivory and gold. The curves of your lips\r
+rewrite history." The phrases came back to his memory, and he repeated\r
+them over and over to himself. Then he loathed his own beauty, and\r
+flinging the mirror on the floor, crushed it into silver splinters\r
+beneath his heel. It was his beauty that had ruined him, his beauty\r
+and the youth that he had prayed for. But for those two things, his\r
+life might have been free from stain. His beauty had been to him but a\r
+mask, his youth but a mockery. What was youth at best? A green, an\r
+unripe time, a time of shallow moods, and sickly thoughts. Why had he\r
+worn its livery? Youth had spoiled him.\r
+\r
+It was better not to think of the past. Nothing could alter that. It\r
+was of himself, and of his own future, that he had to think. James\r
+Vane was hidden in a nameless grave in Selby churchyard. Alan Campbell\r
+had shot himself one night in his laboratory, but had not revealed the\r
+secret that he had been forced to know. The excitement, such as it\r
+was, over Basil Hallward's disappearance would soon pass away. It was\r
+already waning. He was perfectly safe there. Nor, indeed, was it the\r
+death of Basil Hallward that weighed most upon his mind. It was the\r
+living death of his own soul that troubled him. Basil had painted the\r
+portrait that had marred his life. He could not forgive him that. It\r
+was the portrait that had done everything. Basil had said things to\r
+him that were unbearable, and that he had yet borne with patience. The\r
+murder had been simply the madness of a moment. As for Alan Campbell,\r
+his suicide had been his own act. He had chosen to do it. It was\r
+nothing to him.\r
+\r
+A new life! That was what he wanted. That was what he was waiting\r
+for. Surely he had begun it already. He had spared one innocent\r
+thing, at any rate. He would never again tempt innocence. He would be\r
+good.\r
+\r
+As he thought of Hetty Merton, he began to wonder if the portrait in\r
+the locked room had changed. Surely it was not still so horrible as it\r
+had been? Perhaps if his life became pure, he would be able to expel\r
+every sign of evil passion from the face. Perhaps the signs of evil\r
+had already gone away. He would go and look.\r
+\r
+He took the lamp from the table and crept upstairs. As he unbarred the\r
+door, a smile of joy flitted across his strangely young-looking face\r
+and lingered for a moment about his lips. Yes, he would be good, and\r
+the hideous thing that he had hidden away would no longer be a terror\r
+to him. He felt as if the load had been lifted from him already.\r
+\r
+He went in quietly, locking the door behind him, as was his custom, and\r
+dragged the purple hanging from the portrait. A cry of pain and\r
+indignation broke from him. He could see no change, save that in the\r
+eyes there was a look of cunning and in the mouth the curved wrinkle of\r
+the hypocrite. The thing was still loathsome--more loathsome, if\r
+possible, than before--and the scarlet dew that spotted the hand seemed\r
+brighter, and more like blood newly spilled. Then he trembled. Had it\r
+been merely vanity that had made him do his one good deed? Or the\r
+desire for a new sensation, as Lord Henry had hinted, with his mocking\r
+laugh? Or that passion to act a part that sometimes makes us do things\r
+finer than we are ourselves? Or, perhaps, all these? And why was the\r
+red stain larger than it had been? It seemed to have crept like a\r
+horrible disease over the wrinkled fingers. There was blood on the\r
+painted feet, as though the thing had dripped--blood even on the hand\r
+that had not held the knife. Confess? Did it mean that he was to\r
+confess? To give himself up and be put to death? He laughed. He felt\r
+that the idea was monstrous. Besides, even if he did confess, who\r
+would believe him? There was no trace of the murdered man anywhere.\r
+Everything belonging to him had been destroyed. He himself had burned\r
+what had been below-stairs. The world would simply say that he was mad.\r
+They would shut him up if he persisted in his story.... Yet it was\r
+his duty to confess, to suffer public shame, and to make public\r
+atonement. There was a God who called upon men to tell their sins to\r
+earth as well as to heaven. Nothing that he could do would cleanse him\r
+till he had told his own sin. His sin? He shrugged his shoulders.\r
+The death of Basil Hallward seemed very little to him. He was thinking\r
+of Hetty Merton. For it was an unjust mirror, this mirror of his soul\r
+that he was looking at. Vanity? Curiosity? Hypocrisy? Had there\r
+been nothing more in his renunciation than that? There had been\r
+something more. At least he thought so. But who could tell? ... No.\r
+There had been nothing more. Through vanity he had spared her. In\r
+hypocrisy he had worn the mask of goodness. For curiosity's sake he\r
+had tried the denial of self. He recognized that now.\r
+\r
+But this murder--was it to dog him all his life? Was he always to be\r
+burdened by his past? Was he really to confess? Never. There was\r
+only one bit of evidence left against him. The picture itself--that\r
+was evidence. He would destroy it. Why had he kept it so long? Once\r
+it had given him pleasure to watch it changing and growing old. Of\r
+late he had felt no such pleasure. It had kept him awake at night.\r
+When he had been away, he had been filled with terror lest other eyes\r
+should look upon it. It had brought melancholy across his passions.\r
+Its mere memory had marred many moments of joy. It had been like\r
+conscience to him. Yes, it had been conscience. He would destroy it.\r
+\r
+He looked round and saw the knife that had stabbed Basil Hallward. He\r
+had cleaned it many times, till there was no stain left upon it. It\r
+was bright, and glistened. As it had killed the painter, so it would\r
+kill the painter's work, and all that that meant. It would kill the\r
+past, and when that was dead, he would be free. It would kill this\r
+monstrous soul-life, and without its hideous warnings, he would be at\r
+peace. He seized the thing, and stabbed the picture with it.\r
+\r
+There was a cry heard, and a crash. The cry was so horrible in its\r
+agony that the frightened servants woke and crept out of their rooms.\r
+Two gentlemen, who were passing in the square below, stopped and looked\r
+up at the great house. They walked on till they met a policeman and\r
+brought him back. The man rang the bell several times, but there was\r
+no answer. Except for a light in one of the top windows, the house was\r
+all dark. After a time, he went away and stood in an adjoining portico\r
+and watched.\r
+\r
+"Whose house is that, Constable?" asked the elder of the two gentlemen.\r
+\r
+"Mr. Dorian Gray's, sir," answered the policeman.\r
+\r
+They looked at each other, as they walked away, and sneered. One of\r
+them was Sir Henry Ashton's uncle.\r
+\r
+Inside, in the servants' part of the house, the half-clad domestics\r
+were talking in low whispers to each other. Old Mrs. Leaf was crying\r
+and wringing her hands. Francis was as pale as death.\r
+\r
+After about a quarter of an hour, he got the coachman and one of the\r
+footmen and crept upstairs. They knocked, but there was no reply.\r
+They called out. Everything was still. Finally, after vainly trying\r
+to force the door, they got on the roof and dropped down on to the\r
+balcony. The windows yielded easily--their bolts were old.\r
+\r
+When they entered, they found hanging upon the wall a splendid portrait\r
+of their master as they had last seen him, in all the wonder of his\r
+exquisite youth and beauty. Lying on the floor was a dead man, in\r
+evening dress, with a knife in his heart. He was withered, wrinkled,\r
+and loathsome of visage. It was not till they had examined the rings\r
+that they recognized who it was.\r

+\r
+1.F.1. Project Gutenberg volunteers and employees expend considerable\r

+"Defects," such as, but not limited to, incomplete, inaccurate or\r
+corrupt data, transcription errors, a copyright or other intellectual\r
+property infringement, a defective or damaged disk or other medium, a\r
+computer virus, or computer codes that damage or cannot be read by\r
+your equipment.\r
+\r
+1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right\r
+of Replacement or Refund" described in paragraph 1.F.3, the Project\r
+Gutenberg Literary Archive Foundation, the owner of the Project\r

+\r
+Section 2. Information about the Mission of Project Gutenberg-tm\r
+\r
+Project Gutenberg-tm is synonymous with the free distribution of\r
+electronic works in formats readable by the widest variety of computers\r
+including obsolete, old, middle-aged and new computers. It exists\r
+because of the efforts of hundreds of volunteers and donations from\r
+people in all walks of life.\r
+\r
+Volunteers and financial support to provide volunteers with the\r
+assistance they need, is critical to reaching Project Gutenberg-tm's\r
+goals and ensuring that the Project Gutenberg-tm collection will\r
+remain freely available for generations to come. In 2001, the Project\r
+Gutenberg Literary Archive Foundation was created to provide a secure\r
+and permanent future for Project Gutenberg-tm and future generations.\r
+To learn more about the Project Gutenberg Literary Archive Foundation\r
+and how your efforts and donations can help, see Sections 3 and 4\r
+and the Foundation web page at http://www.pglaf.org.\r
+\r
+\r

+\r
+\r
+Section 4. Information about Donations to the Project Gutenberg\r
+Literary Archive Foundation\r
+\r
+Project Gutenberg-tm depends upon and cannot survive without wide\r
+spread public support and donations to carry out its mission of\r
+increasing the number of public domain and licensed works that can be\r
+freely distributed in machine readable form accessible by the widest\r
+array of equipment including outdated equipment. Many small donations\r
+($1 to $5,000) are particularly important to maintaining tax exempt\r
+status with the IRS.\r
+\r
+The Foundation is committed to complying with the laws regulating\r
+charities and charitable donations in all 50 states of the United\r
+States. Compliance requirements are not uniform and it takes a\r
+considerable effort, much paperwork and many fees to meet and keep up\r
+with these requirements. We do not solicit donations in locations\r
+where we have not received written confirmation of compliance. To\r
+SEND DONATIONS or determine the status of compliance for any\r
+particular state visit http://pglaf.org\r
+\r
+While we cannot and do not solicit contributions from states where we\r
+have not met the solicitation requirements, we know of no prohibition\r
+against accepting unsolicited donations from donors in such states who\r
+approach us with offers to donate.\r
+\r
+International donations are gratefully accepted, but we cannot make\r
+any statements concerning tax treatment of donations received from\r
+outside the United States. U.S. laws alone swamp our small staff.\r
+\r
+Please check the Project Gutenberg Web pages for current donation\r
+methods and addresses. Donations are accepted in a number of other\r
+ways including including checks, online payments and credit card\r
+donations. To donate, please visit: http://pglaf.org/donate\r
+\r
+\r
+Section 5. General Information About Project Gutenberg-tm electronic\r
+works.\r
+\r
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm\r
+concept of a library of electronic works that could be freely shared\r
+with anyone. For thirty years, he produced and distributed Project\r
+Gutenberg-tm eBooks with only a loose network of volunteer support.\r
+\r
+\r
+Project Gutenberg-tm eBooks are often created from several printed\r
+editions, all of which are confirmed as Public Domain in the U.S.\r
+unless a copyright notice is included. Thus, we do not necessarily\r
+keep eBooks in compliance with any particular paper edition.\r
+\r
+\r
+Most people start at our Web site which has the main PG search facility:\r
+\r
+ http://www.gutenberg.net\r
+\r
+This Web site includes information about Project Gutenberg-tm,\r

+ This is a demo application for lws generic-sessions.<br><br>
+ It's a simple messageboard.<br><br>
+ What's interesting about it is there is <b>no serverside scripting</b>,<br>
+ instead client js makes a wss:// connection back to the server<br>
+ and then reacts to JSON from the ws protocol. Sessions stuff is <br>
+ handled by lws generic sessions, making the <a href="https://libwebsockets.org/git/libwebsockets/tree/plugins/generic-sessions/protocol_generic_sessions.c">actual<br>
+ test application</a> <a href="https://libwebsockets.org/git/libwebsockets/tree/plugins/generic-sessions/protocol_lws_messageboard.c">very small</a>.<br><br>
+ And because it's natively websocket, it's naturally connected<br>
+ for dynamic events and easy to maintain.

+ Hello from the <b>minimal http server + mimetypes example</b>.
+ <br>
+ This shows how to teach a mount new bindings between file<br>
+ suffix and mimetype used to serve it.<p>
+
+ Lws has a bunch of built-in ones, but you can add as many<br>
+ as you like when defining the mount.<p>
+
+ For example, lws doesn't know the suffix <b>[.tar].bz2</b><br>
+ implies the mimetype <i>application/x-bzip2</i>, but we taught<br>
+ this mount about that relationship in the example code, so it<br>
+ knows how to serve <a href="test.tar.bz2">this example test.tar.bz2</a>.

+# lws minimal http server multivhost
+
+This creates a single server that creates three vhosts listening on both :7681 and
+:7682. Two separate vhosts share listening on :7682.
+
+|vhost|listens on port|serves|
+---|---|---
+localhost1|7681|./mount-origin-localhost1
+localhost2|7682|./mount-origin-localhost2
+localhost3|7682|./mount-origin-localhost3
+
+Notice the last two both listen on 7682. If you visit http://localhost:7682,
+by default you will get mapped to the first one, localhost2.
+
+However if you edit /etc/hosts on your machine and add
+
+```
+127.0.0.1 localhost3
+```
+
+so that you can visit http://localhost3:7682 in your browser, lws will use the
+`Host: localhost3` header sent by your browser to select the localhost3 vhost
+for the connection, and you will be served content from ./mount-origin-localhost3
+
+## build
+
+```
+ $ cmake . && make
+```
+
+## usage
+
+Commandline option|Meaning
+---|---
+-d <loglevel>|Debug verbosity in decimal, eg, -d15
+--die-after-vhost | For testing failure handling

+# lws minimal http server with multithreaded service
+
+Lws supports multithreaded service... build lws with `-DLWS_MAP_SMP=<max number of threads>`, the
+default is 1. If nonzero, some extra pthreads locking is built into lws and it supports multiple
+independent service threads.
+
+
+
+When an incoming connection is accepted, it is bound to the pt with the lowest current wsi
+count, to keep the load on the threads balanced. Only the pt the wsi is bound to can service
+the thread, so although there can be as many wsi being serviced simultaneously as there are
+service threads, a wsi can only be service by the pt it is bound to.
+
+The effectiveness of the scalability depends on the load. Here is an example of roughly what can be expected
+
+
+
+## build
+
+```
+ $ cmake . && make
+```
+
+## usage
+
+```
+ $ ./lws-minimal-http-server-smp

+ * This demonstrates a minimal multithreaded http server you can make with lws.
+ *
+ * To keep it simple, it serves stuff in the subdirectory "./mount-origin" of
+ * the directory it was started in.
+ * You can change that by changing mount.origin.
+ *
+ * Also for simplicity the number of threads is set in the code... note that
+ * the real number of threads possible is decided by the LWS_MAX_SMP that lws
+ * was configured with, by default that is 1. Lws will limit the number of
+ * requested threads to the number possible.

+
+Because :443 uses a selfsigned certificate, you will have to make an exception for it in your browser.
+
+## Certificate creation
+
+The selfsigned certs provided were created with
+
+```
+echo -e "GB\nErewhon\nAll around\nlibwebsockets-test\n\nlocalhost\nnone@invalid.org\n" | openssl req -new -newkey rsa:4096 -days 36500 -nodes -x509 -keyout "localhost-100y.key" -out "localhost-100y.cert"
+```
+
+they cover "localhost" and last 100 years from 2018-03-20.
+
+You can replace them with commercial certificates matching your hostname.
+
+## HTTP/2
+
+If you built lws with `-DLWS_WITH_HTTP2=1` at cmake, this simple server is also http/2 capable
+out of the box. If the index.html was loaded over http/2, it will display an HTTP 2 png.

+ * Written in 2010-2019 by Andy Green <andy@warmcat.com>
+ *
+ * This file is made available under the Creative Commons CC0 1.0
+ * Universal Public Domain Dedication.
+ *
+ * This demonstrates the most minimal http server you can make with lws,
+ * with three extra lines giving it tls (ssl) capabilities, which in
+ * turn allow operation with HTTP/2 if lws was configured for it.
+ *
+ * In addition, it runs a vhost on port 80 with the job of redirecting
+ * and upgrading http clients that came in on port 80 to https on port 443.
+ *
+ * To keep it simple, it serves stuff from the subdirectory
+ * "./mount-origin" of the directory it was started in.
+ *
+ * You can change that by changing mount.origin below.

+# lws minimal http server with tls and certs from memory
+
+This is the same as the minimal-http-server-tls example, but shows how
+to init the vhost with both PEM or DER certs from memory instead of files.
+
+The server listens on port 7681 (initialized with PEM in-memory certs) and
+port 7682 (initialized with DER in-memory certs).

+
+Because it uses a selfsigned certificate, you will have to make an exception for it in your browser.
+
+## Certificate creation
+
+The selfsigned certs provided were created with
+
+```
+echo -e "GB\nErewhon\nAll around\nlibwebsockets-test\n\nlocalhost\nnone@invalid.org\n" | openssl req -new -newkey rsa:4096 -days 36500 -nodes -x509 -keyout "localhost-100y.key" -out "localhost-100y.cert"
+```
+
+they cover "localhost" and last 100 years from 2018-03-20.
+
+You can replace them with commercial certificates matching your hostname.
+
+The der content was made from PEM like this
+
+```
+ $ cat ../minimal-http-server-tls/localhost-100y.key | grep -v ^- | base64 -d | hexdump -C | tr -s ' ' | cut -d' ' -f2- | cut -d' ' -f-16 | sed "s/|.*//g" | sed "s/0000.*//g" | sed "s/^/0x/g" | sed "s/\ /\,\ 0x/g" | sed "s/\$/,/g" | sed "s/0x,//g"
+```
+
+## HTTP/2
+
+If you built lws with `-DLWS_WITH_HTTP2=1` at cmake, this simple server is also http/2 capable
+out of the box. If the index.html was loaded over http/2, it will display an HTTP 2 png.

+Because it uses a selfsigned certificate, you will have to make an exception for it in your browser.
+
+## Certificate creation
+
+The selfsigned certs provided were created with
+
+```
+echo -e "GB\nErewhon\nAll around\nlibwebsockets-test\n\nlocalhost\nnone@invalid.org\n" | openssl req -new -newkey rsa:4096 -days 36500 -nodes -x509 -keyout "localhost-100y.key" -out "localhost-100y.cert"
+```
+
+they cover "localhost" and last 100 years from 2018-03-20.
+
+You can replace them with commercial certificates matching your hostname.
+
+## HTTP/2
+
+If you built lws with `-DLWS_WITH_HTTP2=1` at cmake, this simple server is also http/2 capable
+out of the box. If the index.html was loaded over http/2, it will display an HTTP 2 png.

+
+This example is only meaningful if you are integrating lws in another
+app which generates its own connected sockets. In some cases you may
+want lws to "adopt" the socket.
+
+(If you simply want a connected client raw socket using lws alone, you
+can just use lws_client_connect_via_info() with info.method = "RAW".
+http-client/minimal-http-client shows how to do that, just set
+info.method to "RAW".)
+
+This example demonstrates how to adopt a foreign, connected socket into lws
+as a raw wsi, bound to a specific lws protocol.
+
+The example connects a socket itself to libwebsockets.org:80, and then
+has lws adopt it as a raw wsi. The lws protocol writes "GET / HTTP/1.1"
+to the socket and hexdumps what was sent back.
+
+The socket won't close until the server side times it out, since it's
+a raw socket that doesn't understand it's looking at http.

+# lws minimal ws server raw adopt udp
+
+This example demonstrates echoing packets on a UDP socket in lws.
+
+A "foreign" UDP socket is created, bound (so it can "listen"), and
+adopted into lws event loop. It acts like a tcp RAW mode connection in
+lws and uses the same callbacks.
+
+Writing is a bit different for UDP. By default, the system has no
+idea about the receiver state and so asking for a callback_on_writable()
+always believes that the socket is writeable... the callback will
+happen next time around the event loop if there are no pending partials.
+
+With UDP, there is no "connection". You need to write with sendto() and
+direct the packets to a specific destination. You can learn the source
+of the last packet that arrived at the LWS_CALLBACK_RAW_RX callback by
+getting a `struct lws_udp *` from `lws_get_udp(wsi)`. To be able to
+send back to that guy, you should take a copy of the `struct lws_udp *` and
+use the .sa and .salen members in your sendto().
+
+However the kernel may not accept to buffer / write everything you wanted to send.
+So you are responsible to watch the result of sendto() and resend the
+unsent part next time.

+# lws minimal raw fallback http server
+
+This is the same as the minimal http server, with one difference...
+if you connect to localhost:7681 with something that doesn't send
+recognizable http, then the connection will be switched to a
+raw-skt role and bind to a protocol that echoes anything sent back
+to the sender.
+
+## build
+
+```
+ $ cmake . && make
+```
+
+## usage
+
+Commandline option|Meaning
+---|---
+-d <loglevel>|Debug verbosity in decimal, eg, -d15
+-s|Configure the server for tls / https and `LWS_SERVER_OPTION_ALLOW_NON_SSL_ON_SSL_PORT`
+-h|(needs -s) Configure the vhost also for `LWS_SERVER_OPTION_ALLOW_HTTP_ON_HTTPS_LISTENER`, allowing http service on tls port (caution... it's insecure then)
+-u|(needs -s) Configure the vhost also for `LWS_SERVER_OPTION_REDIRECT_HTTP_TO_HTTPS`, so the server issues a redirect to https to clients that attempt to connect to a server configured for tls with http.

+# lws minimal ws server
+
+This demonstrates adopting a file descriptor into the lws event
+loop. The filepath to open and adopt is given as an argument to the example app, eg
+
+```
+ $ ./lws-minimal-raw-file <file>
+```
+
+On a Linux system, some example files for testing might be
+
+ - /proc/self/fd/0 (stdin)
+ - /dev/ttyUSB0 (a USB <-> serial converter)
+ - /dev/input/event<n> (needs root... input device events)
+
+The example application opens the file in the protocol init
+handler, and hexdumps data from the file to the lws log
+as it becomes available.
+
+This isn't very useful standalone as shown here for clarity, but you can
+freely combine raw file descriptor adoption with other lws server
+and client features.
+
+Becuase raw file events have their own callback reasons, the handlers can
+be integrated in a single protocol that also handles http and ws
+server and client callbacks without conflict.
+
+## build
+
+```
+ $ cmake . && make
+```
+
+## usage
+
+```
+ $ ./lws-minimal-raw-file /proc/self/fd/0

+# lws minimal ws server raw proxy fallback
+
+This demonstrates how a vhost doing normal http or http(s) duty can be also be
+bound to a specific role and protocol as a fallback if the incoming protocol is
+unexpected for tls or http. The example makes the fallback role + protocol
+an lws plugin that performs raw packet proxying.
+
+By default the fallback in the example will proxy 127.0.0.1:22, which is usually
+your ssh server listen port, on 127.0.0.1:7681. You should be able to ssh into
+port 7681 the same as you can port 22. At the same time, you should be able to
+visit http://127.0.0.1:7681 in a browser (and if you give -s, to
+https://127.0.0.1:7681 while your ssh client can still connect to the same
+port.
+
+## build
+
+To build this standalone, you must tell cmake where the lws source tree
+./plugins directory can be found, since it relies on including the source
+of the raw-proxy plugin.
+
+```
+ $ cmake . -DLWS_PLUGINS_DIR=~/libwebsockets/plugins && make
+```
+
+## usage
+
+Commandline option|Meaning
+---|---
+-d <loglevel>|Debug verbosity in decimal, eg, -d15
+-r ipv4:address:port|Configure the remote IP and port that will be proxied, by default ipv4:127.0.0.1:22
+-s|Configure the server for tls / https and `LWS_SERVER_OPTION_ALLOW_NON_SSL_ON_SSL_PORT`
+-h|(needs -s) Configure the vhost also for `LWS_SERVER_OPTION_ALLOW_HTTP_ON_HTTPS_LISTENER`, allowing http service on tls port (caution... it's insecure then)
+-u|(needs -s) Configure the vhost also for `LWS_SERVER_OPTION_REDIRECT_HTTP_TO_HTTPS`, so the server issues a redirect to https to clients that attempt to connect to a server configured for tls with http.
+```
+ $ ./lws-minimal-raw-proxy
+[2018/11/30 19:22:35:7290] USER: LWS minimal raw proxy-fallback
+[2018/11/30 19:22:35:7291] NOTICE: Creating Vhost 'default' port 7681, 1 protocols, IPv6 off

+```
+
+```
+ $ ssh -p7681 me@127.0.0.1
+Last login: Fri Nov 30 19:29:23 2018 from 127.0.0.1

+```
+
+At the same time, visiting http(s)://127.0.0.1:7681 in a browser works fine.

+# lws minimal ws server raw proxy
+
+This demonstrates how a vhost can be bound to a specific role and protocol,
+with the example using a lws plugin that performs raw packet proxying.
+
+By default the example will proxy 127.0.0.1:22, usually your ssh server
+listen port, on 127.0.0.1:7681. You should be able to ssh into port 7681
+the same as you can port 22. But your ssh server is only listening on port 22...
+
+## build
+
+To build this standalone, you must tell cmake where the lws source tree
+./plugins directory can be found, since it relies on including the source
+of the raw-proxy plugin.
+
+```
+ $ cmake . -DLWS_PLUGINS_DIR=~/libwebsockets/plugins && make
+```
+
+## usage
+
+Commandline option|Meaning
+---|---
+-d <loglevel>|Debug verbosity in decimal, eg, -d15
+-r ipv4:address:port|Configure the remote IP and port that will be proxied, by default ipv4:127.0.0.1:22

+# lws minimal ws server raw vhost
+
+This demonstrates setting up a vhost to listen and accept raw sockets.
+Raw sockets are just sockets... lws does not send anything on them or
+interpret by itself what it receives on them. So you can implement
+arbitrary tcp protocols using them.
+
+This isn't very useful standalone as shown here for clarity, but you can
+freely combine a raw socket vhost with other lws server
+and client features and other vhosts handling http or ws.
+
+Becuase raw socket events have their own callback reasons, the handlers can
+be integrated in a single protocol that also handles http and ws
+server and client callbacks without conflict.
+
+## build
+
+```
+ $ cmake . && make
+```
+
+## usage
+
+ -s means listen using tls
+
+```
+ $ ./lws-minimal-raw-vhost

+
+Connect one or more sessions to the server using netcat... lines you type
+into netcat are sent to the server, which echos them to all connected clients.

+ *
+ * You can add more vhosts with things like http or ws support, it's as it is

+ *
+ * The main point is the apis and ways of managing raw sockets are almost
+ * identical to http or ws mode sockets in lws. The callback names for raw

+# lws minimal ws client PING
+
+This connects to libwebsockets.org using the lws-mirror-protocol.
+
+It then sends a ws PING every 5s and records any PONG coming back.
+
+## build
+
+```
+ $ cmake . && make
+```
+
+## Commandline Options
+
+Option|Meaning
+---|---
+-d|Set logging verbosity
+--server|Use a specific server instead of libwebsockets.org, eg `--server localhost`. Implies LCCSCF_ALLOW_SELFSIGNED
+--port|Use a specific port instead of 443, eg `--port 7681`
+-z|Send zero-length pings for testing
+--protocol|Use a specific ws subprotocol rather than lws-mirror-protocol, eg, `--protocol myprotocol`
+
+## usage
+
+Just run it, wait for the connect and then there will be PINGs sent
+at 5s intervals.

+# lws minimal ws client + permessage-deflate for bulk traffic
+
+This example opens a client connection to localhost:7681 where it
+expects to find minimal-ws-server-pmd-bulk running.
+
+It sends and receives a large, multifragment message, and then exits.
+
+## build
+
+```
+ $ cmake . && make
+```
+
+## usage
+
+Both the server and client side must use the same options
+
+ - `-n` disable permessage-deflate extension
+ - `-c` send compressible text instead of uncompressible binary data
+

+# lws minimal ws client rx
+
+## build
+
+```
+ $ cmake . && make
+```
+
+## usage
+
+The application goes to https://libwebsockets.org and makes a wss connection
+using the dumb-increment-protocol. It shows the incrementing number it is
+being sent over ws as it arrives.
+
+This example only receives things to keep it simple. See minimal-ws-client-tx
+for code related to sending things. Of course rx and tx are supported in the
+same protocol.

+# lws minimal ws client SPAM
+
+This connects to libwebsockets.org using the lws-mirror-protocol.
+
+By default is has 10 concurrent connections and connects 100 times.
+
+## build
+
+```
+ $ cmake . && make
+```
+
+## Commandline Options
+
+Option|Meaning
+---|---
+-d|Set logging verbosity
+--server|Use a specific server instead of libwebsockets.org, eg `--server localhost`. Implies LCCSCF_ALLOW_SELFSIGNED
+--port|Use a specific port instead of 443, eg `--port 7681`
+-c|Amount of concurrent connections
+-l|Test limit (total number of connections to make)
+
+## usage
+
+Just run it, it will repeatedly connect and reconnect to libwebsockets.org
+until it hits the test limit.
+
+You can also direct it to use the lws test server in tls mode by running that
+with `libwebsockets-test-server -s` and running this using, eg
+
+```
+ $ ./lws-minimal-ws-client-spam -c 20 -l 200 --server localhost --port 7681
+```
+
+```

+# lws minimal ws client tx
+
+This demonstrates a ws "publisher" to go with the minimal-ws-broker example.
+
+Two threads are spawned that produce messages to be sent to the broker,
+via a local ringbuffer. Locking is provided to make ringbuffer access threadsafe.
+
+When a nailed-up client connection to the broker is established, the
+ringbuffer is sent to the broker, which distributes the events to all
+connected clients.
+
+## build
+
+```
+ $ cmake . && make
+```
+
+## usage
+
+This example connects to ws-server/minimal-ws-broker, so you need to build and run
+that in another terminal.
+
+```
+ $ ./lws-minimal-ws-client-tx
+[2018/03/16 16:04:33:5774] USER: LWS minimal ws client tx
+[2018/03/16 16:04:33:5774] USER: Run minimal-ws-broker and browse to that
+[2018/03/16 16:04:33:5774] NOTICE: Creating Vhost 'default' port -1, 1 protocols, IPv6 off
+[2018/03/16 16:04:34:5794] USER: callback_minimal_broker: established
+```
+
+If you open a browser on http://localhost:7681 , you will see the subscribed
+messages from the threads in this app via the broker app.

+ * ws protocol handler plugin for "lws-minimal-broker"
+ *
+ * Written in 2010-2019 by Andy Green <andy@warmcat.com>
+ *
+ * This file is made available under the Creative Commons CC0 1.0
+ * Universal Public Domain Dedication.
+ *
+ * This implements a minimal "broker", for systems that look like this
+ *
+ * [ publisher ws client ] <-> [ ws server broker ws server ] <-> [ ws client subscriber ]
+ *
+ * The "publisher" role is to add data to the broker.
+ *
+ * The "subscriber" role is to hear about all data added to the system.
+ *
+ * The "broker" role is to manage incoming data from publishers and pass it out
+ * to subscribers.
+ *
+ * Any number of publishers and subscribers are supported.
+ *
+ * This example implements a single ws server, using one ws protocol, that treats ws
+ * connections as being in publisher or subscriber mode according to the URL the ws
+ * connection was made to. ws connections to "/publisher" URL are understood to be
+ * publishing data and to any other URL, subscribing.

+
+Pthreads is required on your system.
+
+This demonstrates how to cleanly assign tasks bound to a wsi to a thread pool,
+with a queue if the pool is occupied.
+
+It creates a threadpool with 3 worker threads and a maxiumum queue size of 4.
+
+The web page at http://localhost:7681 then starts up 8 x ws connections.

+ * The main reason some things are as they are is that the task lifecycle may
+ * be unrelated to the wsi lifecycle that queued that task.
+ *
+ * Consider the task may call an external library and run for 30s without
+ * "checking in" to see if it should stop. The wsi that started the task may
+ * have closed at any time before the 30s are up, with the browser window
+ * closing or whatever.
+ *
+ * So data shared between the asynchronous task and the wsi must have its
+ * lifecycle determined by the task, not the wsi. That means a separate struct
+ * that can be freed by the task.
+ *
+ * In the case the wsi outlives the task, the tasks do not get destroyed until
+ * the service thread has called lws_threadpool_task_status() on the completed
+ * task. So there is no danger of the shared task private data getting randomly
+ * freed.

+# lws minimal ws server (threads) + SMP
+
+This demonstrates both independent threads creating content
+as in the -threads example, and multiple service threads
+as in the http-server-smp example (but with ws).
+
+## build
+
+You must first build libwebsockets itself with cmake `-DLWS_MAX_SMP=8`
+or some other number greater than one.
+
+```
+ $ cmake . && make
+```
+
+Pthreads is required on your system.
+
+## usage
+
+```
+ $ ./lws-minimal-ws-server-threads-smp
+[2019/01/28 06:59:17:4217] USER: LWS minimal ws server + threads + smp | visit http://localhost:7681
+[2019/01/28 06:59:17:4219] NOTICE: Service threads: 2
+[2019/01/28 06:59:17:4220] NOTICE: LWS_CALLBACK_EVENT_WAIT_CANCELLED in svc tid 0x7fec48af8700
+[2019/01/28 06:59:17:4220] NOTICE: LWS_CALLBACK_EVENT_WAIT_CANCELLED in svc tid 0x7fec48af8700
+...
+```
+
+Visit http://localhost:7681 on multiple browser windows. You may need to open
+4 before the second service thread is used (check "svc tid" in the browser output).
+
+Two lws service threads are started.
+
+Two separate asynchronous threads generate strings and add them to a ringbuffer,
+signalling all lws service threads to send new entries to all the browser windows.
+
+This demonstrates how to safely manage asynchronously generated content
+and hook it up to the lws service threads.

+# Deaddrop: File upload and sharing plugin
+
+## Building the plugin
+
+Just configure lws with `cmake .. -DLWS_WITH_PLUGINS=1` and build lws as normal.
+
+## Configurable settings
+
+|pvo name|value meaning|
+|---|---|
+|upload-dir|A writeable directory where uploaded files will go|
+|max-size|Maximum individual file size in bytes|
+|basic-auth|Path to basic auth credential file so wss can also be protected|
+
+## Required mounts
+
+To use deaddrop meaningfully, all the mounts and the ws protocol must be
+protected by basic auth. And to use basic auth securely, the connection must
+be protected from snooping by tls.
+
+1) Set the basic-auth pvo to require valid credentials as described above
+
+2) Protect your basic fileserving mount by the same basic auth file... this is
+ used to serve index.html, the css etc.
+
+3) Add a callback mount into "lws-deaddrop" protocol at "upload"... so if your
+ URL for deaddrop is "/tools/share", this would be at "/tools/share/upload".
+ It must also be protected by the basic auth file.
+
+4) Add a fileserving mount at the url "get" (continuing the example above, it
+ would be "/tools/share/get" whose origin matches the "upload-dir" pvo
+ value you selected. This mount needs any additional mimtype mappings since
+ it's where the uploaded files are shared from.
+
+## Using with C
+
+See ./minimal-examples/http-server/minimal-example-http-server-deaddrop for
+how to use the plugin directly with C.
+
+## Using with lwsws / lejp-conf
+
+As a plugin, you can configure the mounts and pvos per-vhost easily in JSON.
+
+All the snippets here
+
+The mountpoints would look something like this (added to vhost/mounts)
+
+```
+ {
+ "mountpoint": "/tools/share",
+ "origin": "file:///var/www/deaddrop",
+ "default": "index.html",
+ "basic-auth": "/var/www/ba"
+ }, {
+ "mountpoint": "/tools/share/upload",
+ "origin": "callback://lws-deaddrop",
+ "basic-auth": "/var/www/ba"
+ }, {
+ "mountpoint": "/tools/share/get",
+ "origin": "file:///var/cache/deaddrop-uploads",
+ "basic-auth": "/var/www/ba",
+
+ "extra-mimetypes": {
+ ".bin": "application/octet-stream",
+ ".ttf": "application/x-font-truetype",
+ ".otf": "application/font-sfnt",
+ ".zip": "application/zip",
+ ".webm": "video/webm",
+ ".romfs": "application/octet-stream",
+ ".pdf": "application/pdf",
+ ".odt": "application/vnd.oasis.opendocument.text",
+ ".tgz": "application/x-gzip",
+ ".tar.gz": "application/x-gzip"
+ }
+ }
+```
+
+This enables the plugin on the vhost, configures the pvos, and makes
+the wss serving also depend on having a valid basic auth credential.
+
+```
+ "ws-protocols": [{
+ "lws-deaddrop": {
+ "status": "ok",
+ "upload-dir": "/var/cache/deaddrop-uploads",
+ "max-size": "52428800",
+ "basic-auth": "/var/www/ba"
+ }

It's a simple messageboard.<br><br>
What's interesting about it is there is <b>no serverside scripting</b>,<br>
instead client js makes a wss:// connection back to the server<br>
and then reacts to JSON from the ws protocol. Sessions stuff is <br>

And because it's natively websocket, it's naturally connected<br>
for dynamic events and easy to maintain.

+Notice that since it proxies the packets "raw", there's no SNI or Host:
+header to resolve amongst multiple vhosts on the same listen port. So the
+vhost you associate with this protocol must be alone on its own port.
+
+It's also possible to apply this or other role + protocols as a fallback after
+http[s] processing rejected the first packet from an incoming connection.
+See `./READMEs/README-http-fallback.md`
+
+## Note for packet size
+
+For throughput, since often one side is localhost that can handle larger
+packets easily, you should create the context used with this plugin with
+
+```
+ info.pt_serv_buf_size = 8192;
+```
+
+lwsws already does this.
+
+## Using with C
+
+See the minimal example `./minimal-example/raw/minimal-raw-proxy` for
+a working example of a vhost that accepts connections and then
+proxies them using this plugin. The example is almost all boilerplate
+for setting up the context and the pvo.
+
+## Using with lwsws
+
+For a usage where the plugin "owns" the whole vhost, you should enable the
+plugin protocol on the vhost as usual, and specify the "onward" pvo with:
+
+```
+ "ws-protocols": [{
+ "raw-proxy": {
+ "status": "ok",
+ "onward": "ipv4:remote.address.com:port"
+ }
+ }],
+```
+
+and then define the vhost with:
+
+```
+ "apply-listen-accept": "1",
+ "listen-accept-role": "raw-proxy",
+ "listen-accept-protocol": "raw-proxy"
+```
+
+which tells it to apply the role and protocol as soon as a connection is
+accepted on the vhost.
