come　and　gone　since　the　wonderful　pages　of　history　were　opened　to
  us。　　And　during　all　these　years　how　much　nearer　have　the　serf　and
  the　aristocrat　come　together？　　Nay；　have　they　not　rather　drifted
  apart？　。。。　But　listen！　　This　is　the　great　chorus。　　We　must　not
  miss　it。〃
  〃So　the　Prince　has　brought　back　the　wanderer；〃　Lady　Carey　whispered
  to　Mr。　Sabin　behind　her　fan。　　〃Hasn't　he　rather　the　air　of　a　sheep
  who　has　strayed　from　the　fold？〃
  Mr。　Sabin　raised　the　horn　eyeglass；　which　he　so　seldom　used；　and
  contemplated　Brott　steadily。
  〃He　reminds　me　more　than　ever；〃　he　remarked；　〃of　Rienzi。　　He　is
  like　a　man　torn　asunder　by　great　causes。　　They　say　that　his　speech
  at　Glasgow　was　the　triumph　of　a　born　orator。〃
  Lady　Carey　shrugged　her　shoulders。
  〃It　was　practically　the　preaching　a　revolution　to　the　people；〃　she
  said。　　〃A　few　more　such；　and　we　might　have　the　red　flag　waving。　　He
  left　Glasgow　in　a　ferment。　　If　he　really　comes　into　power；　what　are
  we　to　expect？〃
  〃To　the　onlookers；〃　Mr。　Sabin　remarked；　〃a　revolution　in　this
  country　would　possess　many　interesting　features。　　The　common　people
  lack　the　ferocity　of　our　own　rabble；　but　they　are　even　more
  determined。　　I　may　yet　live　to　see　an　English　Duke　earning　an　honest
  living　in　the　States。〃
  〃It　depends　very　much　upon　Brott；〃　Lady　Carey　said。　　〃For　his　own
  sake　it　is　a　pity　that　he　is　in　love　with　Lucille。〃
  Mr。　Sabin　agreed　with　her　blandly。
  〃It　is；〃　he　affirmed；　〃a　most　regrettable　incident。〃
  She　leaned　a　little　towards　him。　　The　box　was　not　a　large　one；　and
  their　chairs　already　touched。
  〃Are　you　a　jealous　husband？〃　she　asked。
  〃Horribly；〃　be　answered。
  〃Your　devotion　to　Lucille；　or　rather　the　singleness　of　your　devotion
  to　Lucille；〃　she　remarked；　〃is　positively　the　most　gauche　thing　about
  you。　　It　is　…　absolutely　callow！〃
  He　laughed　gently。
  〃Did　I　not　always　tell　you；〃　he　said；　〃that　when　I　did　marry　I
  should　make　an　excellent　husband？〃
  〃You　are　at　least；〃　she　answered　sharply；　〃a　very　complaisant　one。〃
  The　Prince　leaned　forward　from　the　shadows　of　the　box。
  〃I　invite　you　all；〃　he　said；　〃to　supper　with　me。　　It　is　something
  of　an　occasion；　this！　　For　I　do　not　think　that　we　shall　all　meet
  again　just　as　we　are　now　for　a　very　long　time。〃
  〃Your　invitation；〃　Mr。　Sabin　remarked；　〃is　most　agreeable。　　But
  your　suggestion　is；　to　say　the　least　of　it；　nebulous。　　I　do　not　see
  what　is　to　prevent　your　all　having　supper　with　me　to…morrow　evening。
  Lady　Carey　laughed　as　she　rose；　and　stretched　out　her　hand　for　her
  cloak。
  〃To…morrow　evening；〃　she　said；　〃is　a　long　way　off。　　Let　us　make
  sure　of　to…night　…　before　the　Prince　changes　his　mind。〃
  Mr。　Sabin　bowed　low。
  〃To…night　by　all　means；〃　he　declared。　　〃But　my　invitation　remains
  …　a　challenge！〃
  CHAPTER　XXXI
  The　Prince；　being　host；　arranged　the　places　at　his　supper…table。
  Mr。　Sabin　found　himself；　therefore；　between　Lady　Carey　and　a　young
  German　attache；　whom　they　had　met　in　the　ante…room　of　the　restaurant。
  Lucille　had　the　Prince　and　Mr。　Brott　on　either　side　of　her。
  Lady　Carey　monopolised　at　first　the　greater　part　of　the　conversation。
  Mr。　Sabin　was　unusually　silent。　　The　German　attache；　whose　name　was
  Baron　von　Opperman；　did　not　speak　until　the　champagne　was　served；
  when　he　threw　a　bombshell　into　the　midst　of　the　little　party。
  〃I　hear；〃　he　said；　with　a　broad　and　seraphic　smile；　〃that　in　this
  hotel　there　has　to…day　a　murder　been　committed。〃
  Baron　von　Opperman　was　suddenly　the　cynosure　of　several　pairs　of
  eyes。　　He　was　delighted　with　the　success　of　his　attempt　towards
  the　general　entertainment。
  〃The　evening　papers；〃　he　continued；　〃they　have　in　them　news　of　a
  sudden　death。　　But　in　the　hotel　here　now　they　are　speaking　of
  something　…　what　you　call　more　…　mysterious。　　There　has　been　ordered
  an　examination　post…mortem！〃
  〃It　is　a　case　of　poisoning　then；　I　presume？〃　the　Prince　asked；
  leaning　forward。
  〃It　is　so　supposed；〃　the　attache　answered。　　〃It　seems　that　the
  doctors　could　find　no　trace　of　disease；　nothing　to　have　caused　death。
  They　were　not　able　to　decide　anything。　　The　man；　they　said；　was　in
  perfect　health　…　but　dead。〃
  〃It　must　have　been；　then；〃　the　Prince　remarked；　〃a　very　wonderful
  poison。〃
  〃Without　doubt；〃　Baron　Opperman　answered。
  The　Prince　sighed　gently。
  〃There　are　many　such；〃　he　murmured。　　〃Indeed　the　science　of
  toxicology　was　never　so　ill…understood　as　now。　　I　am　assured　that
  there　are　many　poisons　known　only　to　a　few　chemists　in　the　world；　a
  single　grain　of　which　is　sufficient　to　destroy　the　strongest　man
  and　leave　not　the　slightest　trace　behind。　　If　the　poisoner　be
  sufficiently　accomplished　he　can　pursue　his　…　calling　without　the
  faintest　risk　of　detection。〃
  Mr。　Sabin　sipped　his　wine　thoughtfully。
  〃The　Prince　is；　I　believe；　right；〃　he　remarked。　　〃It　is　for　that
  reason；　doubtless；　that　I　have　heard　of　men　whose　lives　have　been
  threatened；　who　have　deposited　in　safe　places　a　sealed　statement　of
  the　danger　in　which　they　find　themselves；　with　an　account　of　its
  source；　so　that　if　they　should　come　to　an　end　in　any　way　mysterious
  there　may　be　evidence　against　their　murderers。〃
  〃A　very　reasonable　and　judicious　precaution；〃　the　Prince　remarked
  with　glittering　eyes。　　〃Only　if　the　poison　was　indeed　of　such　a
  nature　that　it　was　not　possible　to　trace　it　nothing　worse　than
  suspicion　could　ever　be　the　lot　of　any　one。〃
  Mr。　Sabin　helped　himself　carefully　to　salad；　and　resumed　the
  discussion　with　his　next　course。
  〃Perhaps　not；〃　he　admitted。　　〃But　you　must　remember　that　suspicion
  is　of　itself　a　grievous　embarrassment。　　No　man　likes　to　feel　that
  he　is　being　suspected　of　murder。　　By　the　bye；　is　it　known　whom　the
  unfortunate　person　was？〃
  〃The　servant　of　a　French　nobleman　who　is　staying　in　the　hotel；〃　Mr。
  Brott　remarked。　　〃I　heard　as　much　as　that。〃
  Mr。　Sabin　smiled。　　Lady　Carey　glanced　at　him　meaningly。
  〃You　have　worried　the　Prince　quite　sufficiently；〃　she　whispered。
  〃Change　the　subject。〃
  Mr。　Sabin　bowed。
  〃You　are　very　considerate　…　to　the　Prince；〃　he　said。
  〃It　is　perhaps　for　your　sake；〃　she　answered。　　〃And　as　for　the　Prince
  …　well；　you　know；　or　you　should　know；　for　how　much　he　counts　with
  me。〃
  Mr。　Sabin　glanced　at　her　curiously。　　She　was　a　little　flushed　as
  though　with　some　inward　excitement。　　Her　eyes　were　bright　and　soft。
  Despite　a　certain　angularity　of　figure　and　her　hollow　cheeks　she　was
  certainly　one　of　the　most　distinguished…looking　women　in　the　room。
  〃You　are　so　dense；〃　she　whispered　in　his　ear；　〃wilfully　dense；
  perhaps。　　You　will　not　understand　that　I　wish　to　be　your　friend。〃
  He　smiled　with　gentle　deprecation。
  〃Do　you　blame　me；〃　he　murmured；　〃if　I　seem　incredulous？　　For　I　am
  an　old　man；　and　you　are　spoken　of　always　as　the　friend　of　my　enemy；
  the　friend　of　the　Prince。〃
  〃I　wonder；〃　she　said　thoughtfully；　〃if　this　is　really　the　secret
  of　your　mistrust？　　Do　you　indeed　fear　that　I　have　no　other　interest
  in　life　save　to　serve　Saxe　Leinitzer？〃
  〃As　to　that；〃　he　answered；　〃I　cannot　say。　　Yet　I　know　that　only　a
  few　months　ago　you　were　acting　under　orders　from　him。　　It　is　you
  who　brought　Lucille　from　America。　　It　was　through　you　that　the　first
  blow　was　struck　at　my　happiness。〃
  〃Cannot　I　atone？〃　she　murmured　under　her　breath。　　〃If　I　can　I　will。
  And　as　for　the　present；　well；　I　am　outside　his　schemes　now。　　Let　us
  be　friends。　　You　would　find　me　a　very　valuable　ally。〃
  〃Let　it　be　so；〃　he　answered　without　emotion。　　〃You　shall　help　me；
  if　you　will；　to　regain　Lucille。　　I　promise　you　then　that　my　gratitude
  shall　not　disappoint　you。〃
  She　bit　her　lip。
  〃And　are　you　sure；〃　she　whispered；　〃that　Lucille　is　anxious　to　be
  won　back？　She　loves　intrigue；　excitement；　the　sense　of　being
  concerned　in　important　doings。　　Besides　…　you　must　have　heard　what
  they　say　about　her　…　and　Brott。　　Look　at　her　now。　　She　wears
  her　grass　widowhood　lightly　enough。〃
  Mr。　Sabin　looked　across　the　table。　　Lucille　had　indeed　all　the
  appearance　of　a　woman　thoroughly　at　peace　with　the　world　and　herself。
  Brott　was　talking　to　her　in　smothered　and　eager　undertones。　　The
  Prince　was　waiting　for　an　opportunity　to　intervene。　　Mr。　Sabin
  looked　into　Brott's　white　strong　face；　and　was　thoughtful。
  〃It　is　a　great　power　…　the　power　of　my　sex；〃　Lady　Carey　continued；
  with　a　faint；　subtle　smile。　　〃A　word　from　Lucille；　and　the　history
  book　of　the　future　must　be　differently　written。〃
  〃She　will　not　speak　that　word；〃　Mr。　Sabin　said。　　Lady　Carey　shrugged
  her　shoulders。　　The　subtlety　of　her　smile　faded　away。　　Her　whole
  face　expressed　a　contemptuous　and　self…assured　cynicism。
  〃You　know　her　very　well；〃　she　murmured。　　〃Yet　she　and　I　are　no
  strangers。　　She　is　one　who　loves　to　taste　…　no；　to　drink　…　deeply
  of　all　the　experiences　of　life。　　Why　should　we　blame　her；　you　and
  I？　　Have　we　not　the　same　desire？〃
  Mr。　Sabin　lit　a　cigarette。
  〃Once；　perhaps；〃　he　remarked。　　〃You　must　not　forget　that　I　am　no
  longer　a　young　man。〃
  She　leaned　towards　him。
  〃You　will　die　young；〃　she　murmured。　　〃You　are　not　of　the　breed　of
  men　who　grow　old。〃
  〃Do　you　mean　to　turn　my　head？〃　he　asked　her；　with　a　humorous　smile。
  〃It　would　be　easier；〃　she　answered；　〃than　to　touch　your　heart。〃
  Then　Lucille　looked　across
