but　the　blinds　inside　of　them　were　drawn；　as　I　had　myself　drawn
  them　early　in　the　evening；　as　I　did　every　day；　though　Mademoiselle；
  knowing　that　I　was　tired　from　the　heavy　work　I　had　been　doing；　had
  begged　me　not　to　trouble　myself；　but　leave　her　to　do　it；　and　they
  were　just　as　I　had　left　them；　fastened　with　an　iron　catch　on　the
  inside。　　The　assassin；　therefore；　could　not　have　passed　either　in
  or　out　that　way；　but　neither　could　I　get　in。
  〃'It　was　unfortunate；　…　enough　to　turn　one's　brain！　　The　door　of
  the　room　locked　on　the　inside　and　the　blinds　on　the　only　window
  also　fastened　on　the　inside；　and　Mademoiselle　still　calling　for
  help！　　…　No！　　she　had　ceased　to　call。　　She　was　dead；　perhaps。　　But
  I　still　heard　her　father；　in　the　pavilion；　trying　to　break　down
  the　door。
  〃'With　the　concierge　I　hurried　back　to　the　pavilion。　　The　door；
  in　spite　of　the　furious　attempts　of　Monsieur　Stangerson　and　Bernier
  to　burst　it　open；　was　still　holding　firm；　but　at　length；　it　gave
  way　before　our　united　efforts；　…　and　then　what　a　sight　met　our　eyes！
  I　should　tell　you　that；　behind　us；　the　concierge　held　the　laboratory
  lamp　…　a　powerful　lamp；　that　lit　the　whole　chamber。
  〃'I　must　also　tell　you；　monsieur；　that　The　Yellow　Room　is　a　very
  small　room。　　Mademoiselle　had　furnished　it　with　a　fairly　large　iron
  bedstead；　a　small　table；　a　night…commode；　a　dressing…table；　and　two
  chairs。　　By　the　light　of　the　big　lamp　we　saw　all　at　a　glance。
  Mademoiselle；　in　her　night…dress；　was　lying　on　the　floor　in　the
  midst　of　the　greatest　disorder。　　Tables　and　chairs　had　been
  overthrown；　showing　that　there　had　been　a　violent　struggle。
  Mademoiselle　had　certainly　been　dragged　from　her　bed。　　She　was
  covered　with　blood　and　had　terrible　marks　of　finger…nails　on　her
  throat；　…　the　flesh　of　her　neck　having　been　almost　torn　by　the
  nails。　　From　a　wound　on　the　right　temple　a　stream　of　blood　had　run
  down　and　made　a　little　pool　on　the　floor。　　When　Monsieur　Stangerson
  saw　his　daughter　in　that　state；　he　threw　himself　on　his　knees　beside
  her；　uttering　a　cry　of　despair。　　He　ascertained　that　she　still
  breathed。　　As　to　us；　we　searched　for　the　wretch　who　had　tried　to
  kill　our　mistress；　and　I　swear　to　you；　monsieur；　that；　if　we　had
  found　him；　it　would　have　gone　hard　with　him！
  〃'But　how　to　explain　that　he　was　not　there；　that　he　had　already
  escaped？　　It　passes　all　imagination！　　…　Nobody　under　the　bed；　nobody
  behind　the　furniture！　　…　All　that　we　discovered　were　traces；
  blood…stained　marks　of　a　man's　large　hand　on　the　walls　and　on　the
  door；　a　big　handkerchief　red　with　blood；　without　any　initials；　an
  old　cap；　and　many　fresh　footmarks　of　a　man　on　the　floor；　…　footmarks
  of　a　man　with　large　feet　whose　boot…soles　had　left　a　sort　of　sooty
  impression。　　How　had　this　man　got　away？　　How　had　he　vanished？　　Don't
  forget；　monsieur；　that　there　is　no　chimney　in　The　Yellow　Room。　　He
  could　not　have　escaped　by　the　door；　which　is　narrow；　and　on　the
  threshold　of　which　the　concierge　stood　with　the　lamp；　while　her
  husband　and　I　searched　for　him　in　every　corner　of　the　little　room；
  where　it　is　impossible　for　anyone　to　hide　himself。　　The　door；　which
  had　been　forced　open　against　the　wall；　could　not　conceal　anything
  behind　it；　as　we　assured　ourselves。　　By　the　window；　still　in　every
  way　secured；　no　flight　had　been　possible。　　What　then？　　…　I　began
  to　believe　in　the　Devil。
  〃'But　we　discovered　my　revolver　on　the　floor！　　…　Yes；　my　revolver！
  Oh！　　that　brought　me　back　to　the　reality！　　The　Devil　would　not　have
  needed　to　steal　my　revolver　to　kill　Mademoiselle。　　The　man　who　had
  been　there　had　first　gone　up　to　my　attic　and　taken　my　revolver　from
  the　drawer　where　I　kept　it。　　We　then　ascertained；　by　counting　the
  cartridges；　that　the　assassin　had　fired　two　shots。　　Ah！　　it　was
  fortunate　for　me　that　Monsieur　Stangerson　was　in　the　laboratory
  when　the　affair　took　place　and　had　seen　with　his　own　eyes　that　I
  was　there　with　him；　for　otherwise；　with　this　business　of　my　revolver；
  I　don't　know　where　we　should　have　been；　…　I　should　now　be　under　lock
  and　bar。　　Justice　wants　no　more　to　send　a　man　to　the　scaffold！'〃
  The　editor　of　the　〃Matin〃　added　to　this　interview　the　following
  lines：
  〃We　have；　without　interrupting　him；　allowed　Daddy　Jacques　to　recount
  to　us　roughly　all　he　knows　about　the　crime　of　The　Yellow　Room。　　We
  have　reproduced　it　in　his　own　words；　only　sparing　the　reader　the
  continual　lamentations　with　which　he　garnished　his　narrative。　　It　is
  quite　understood；　Daddy　Jacques；　quite　understood；　that　you　are　very
  fond　of　your　masters；　and　you　want　them　to　know　it；　and　never　cease
  repeating　it　…　especially　since　the　discovery　of　your　revolver。　　It
  is　your　right；　and　we　see　no　harm　in　it。　　We　should　have　liked　to
  put　some　further　questions　to　Daddy　Jacques　…　Jacques　…　Louis
  Moustier　…　but　the　inquiry　of　the　examining　magistrate；　which　is
  being　carried　on　at　the　chateau；　makes　it　impossible　for　us　to　gain
  admission　at　the　Glandier；　and；　as　to　the　oak　wood；　it　is　guarded
  by　a　wide　circle　of　policemen；　who　are　jealously　watching　all　traces
  that　can　lead　to　the　pavilion；　and　that　may　perhaps　lead　to　the
  discovery　of　the　assassin。　　〃We　have　also　wished　to　question　the
  concierges；　but　they　are　invisible。　　Finally；　we　have　waited　in　a
  roadside　inn；　not　far　from　the　gate　of　the　chateau；　for　the　departure
  of　Monsieur　de　Marquet；　the　magistrate　of　Corbeil。　　At　half…past
  five　we　saw　him　and　his　clerk　and；　before　he　was　able　to　enter　his
  carriage；　had　an　opportunity　to　ask　him　the　following　question：
  〃'Can　you；　Monsieur　de　Marquet；　give　us　any　information　as　to　this
  affair；　without　inconvenience　to　the　course　of　your　inquiry？'
  〃'It　is　impossible　for　us　to　do　it；'　replied　Monsieur　de　Marquet。
  'I　can　only　say　that　it　is　the　strangest　affair　I　have　ever　known。
  The　more　we　think　we　know　something；　the　further　we　are　from　knowing
  anything！'
  〃We　asked　Monsieur　de　Marquet　to　be　good　enough　to　explain　his　last
  words；　and　this　is　what　he　said；　…　the　importance　of　which　no　one
  will　fail　to　recognise：
  〃'If　nothing　is　added　to　the　material　facts　so　far　established；　I
  fear　that　the　mystery　which　surrounds　the　abominable　crime　of　which
  Mademoiselle　Stangerson　has　been　the　victim　will　never　be　brought　to
  light；　but　it　is　to　be　hoped；　for　the　sake　of　our　human　reason；　that
  the　examination　of　the　wails；　and　of　the　ceiling　of　The　Yellow　Room
  …　an　examination　which　I　shall　to…morrow　intrust　to　the　builder　who
  constructed　the　pavilion　four　years　ago　…　will　afford　us　the　proof
  that　may　not　discourage　us。　　For　the　problem　is　this：　we　know　by
  what　way　the　assassin　gained　admission；　…　he　entered　by　the　door　and
  hid　himself　under　the　bed；　awaiting　Mademoiselle　Stangerson。　　But
  how　did　he　leave？　　How　did　he　escape？　　If　no　trap；　no　secret　door；
  no　hiding　place；　no　opening　of　any　sort　is　found；　if　the　examination
  of　the　walls　…　even　to　the　demolition　of　the　pavilion　…　does　not
  reveal　any　passage　practicable　…　not　only　for　a　human　being；　but　for
  any　being　whatsoever　…　if　the　ceiling　shows　no　crack；　if　the　floor
  hides　no　underground　passage；　one　must　really　believe　in　the　Devil；
  as　Daddy　Jacques　says！'〃
  And　the　anonymous　writer　in　the　〃Matin〃　added　in　this　article
  …　which　I　have　selected　as　the　most　interesting　of　all　those　that
  were　published　on　the　subject　of　this　affair　…　that　the　examining
  magistrate　appeared　to　place　a　peculiar　significance　to　the　last
  sentence：　〃One　must　really　believe　in　the　Devil；　as　Jacques　says。
  The　article　concluded　with　these　lines：　〃We　wanted　to　know　what
  Daddy　Jacques　meant　by　the　cry　of　the　Bete　Du　Bon　Dieu。〃　　The
  landlord　of　the　Donjon　Inn　explained　to　us　that　it　is　the
  particularly　sinister　cry　which　is　uttered　sometimes　at　night　by
  the　cat　of　an　old　woman；　…　Mother　Angenoux；　as　she　is　called　in
  the　country。　　Mother　Angenoux　is　a　sort　of　saint；　who　lives　in　a
  hut　in　the　heart　of　the　forest；　not　far　from　the　grotto　of
  Sainte…Genevieve。
  〃The　Yellow　Room；　the　Bete　Du　Bon　Dieu；　Mother　Angenoux；　the　Devil；
  Sainte…Genevieve；　Daddy　Jacques；　…　here　is　a　well　entangled　crime
  which　the　stroke　of　a　pickaxe　in　the　wall　may　disentangle　for　us
  to…morrow。　　Let　us　at　least　hope　that；　for　the　sake　of　our　human
  reason；　as　the　examining　magistrate　says。　　Meanwhile；　it　is　expected
  that　Mademoiselle　Stangerson　…　who　has　not　ceased　to　be　delirious
  and　only　pronounces　one　word　distinctly；　'Murderer！　　Murderer！'
  …　will　not　live　through　the　night。〃
  In　conclusion；　and　at　a　late　hour；　the　same　journal　announced　that
  the　Chief　of　the　Surete　had　telegraphed　to　the　famous　detective；
  Frederic　Larsan；　who　had　been　sent　to　London　for　an　affair　of
  stolen　securities；　to　return　immediately　to　Paris。
  CHAPTER　II
  In　Which　Joseph　Rouktabille　Appears　for　the　First　Time
  I　remember　as　well　as　if　it　had　occurred　yesterday；　the　entry　of
  young　Rouletabille　into　my　bedroom　that　morning。　　It　was　about
  eight　o'clock　and　I　was　still　in　bed　reading　the　article　in　the
  〃Matin〃　relative　to　the　Glandier　crime。
  But；　before　going　further；　it　is　time　that　I　present　my　friend
  to　the　reader。
  I　first　knew　Joseph　Rouletabille　when　he　was　a　young　reporter。　　At
