at　all　disordered　when　he　talks　on　ordinary　topics？〃
  〃Not　in　the　least。　When　you　can　get　him　to　say　anything；　which　is
  not　often；　he　talks　like　a　sensible；　well…educated　man。　Keep
  silence　about　his　precious　errand　here；　and　you　would　fancy　him
  the　gentlest　and　most　temperate　of　human　beings；　but　touch　the
  subject　of　his　vagabond　of　an　uncle；　and　　the　Monkton　madness
  comes　out　directly。　The　other　night　a　lady　asked　him；　jestingly
  of　course；　whether　he　had　ever　seen　his　uncle's　ghost。　He　scowled
  at　her　like　a　perfect　fiend；　and　said　that　he　and　his　uncle　would
  answer　her　question　together　some　day；　if　they　came　from　hell　to
  do　it。　We　laughed　at　his　words；　but　the　lady　fainted　at　his
  looks；　and　we　had　a　scene　of　hysterics　and　hartshorn　in
  consequence。　Any　other　man　would　have　been　kicked　out　of　the　room
  for　nearly　frightening　a　pretty　woman　to　death　in　that　way；　but
  'Mad　Monkton；'　as　we　have　christened　him；　is　a　privileged　lunatic
  in　Neapolitan　society；　because　he　is　English；　good…looking；　and
  worth　thirty　thousand　a　year。　He　goes　out　everywhere　under　the
  impression　that　he　may　meet　with　somebody　who　has　been　let　into
  the　secret　of　the　place　where　the　mysterious　duel　was　fought。　If
  you　are　introduced　to　him　he　is　sure　to　ask　you　whether　you　know
  anything　about　it；　but　beware　of　following　up　the　subject　after
  you　have　answered　him；　unless　you　want　to　make　sure　that　he　is
  out　of　his　senses。　In　that　case；　only　talk　of　his　uncle；　and　the
  result　will　rather　more　than　satisfy　you。〃
  A　day　or　two　after　this　conversation　with　my　friend　the
  _attache；_　I　met　Monkton　at　an　evening　party。
  The　moment　he　heard　my　name　mentioned；　his　face　flushed　up；　he
  drew　me　away　into　a　corner；　and　referring　to　his　cool　reception
  of　my　advance　years　ago　toward　making　his　acquaintance；　asked　my
  pardon　for　what　he　termed　his　inexcusable　ingratitude　with　an
  earnestness　and　an　agitation　which　utterly　astonished　me。　His
  next　proceeding　was　to　question　me；　as　my　friend　had　said　he
  would；　about　the　place　of　the　mysterious　duel。
  An　extraordinary　change　came　over　him　while　he　interrogated　me　on
  this　point。　Instead　of　looking　into　my　face　as　they　had　looked
  hitherto；　his　eyes　wandered　away；　and　fixed　themselves　intensely；
  almost　fiercely；　either　on　the　perfectly　empty　wall　at　our　side；
  or　on　the　vacant　space　between　the　wall　and　ourselves；　it　was
  impossible　to　say　which。　I　had　come　to　Naples　from　Spain　by　sea；
  and　briefly　told　him　so；　as　the　best　way　of　satisfying　him　that　I
  could　not　assist　his　inquiries。　He　pursued　them　no　further；　and；
  mindful　of　my　friend's　warning；　I　took　care　to　lead　the
  conversation　to　general　topics。　He　looked　back　at　me　directly；
  and；　as　long　as　we　stood　in　our　corner；　his　eyes　never　wandered
  away　again　to　the　empty　wall　or　the　vacant　space　at　our　side。
  Though　more　ready　to　listen　than　to　speak；　his　conversation；　when
  he　did　talk；　had　no　trace　of　anything　the　least　like　insanity
  about　it。　He　had　evidently　read；　not　generally　only；　but　deeply
  as　well；　and　could　apply　his　reading　with　singular　felicity　to
  the　illustration　of　almost　any　subject　under　discussion；　neither
  obtruding　his　knowledge　absurdly；　nor　concealing　it　affectedly。
  His　manner　was　in　itself　a　standing　protest　against　such　a
  nickname　as　〃Mad　Monkton。〃　He　was　so　shy；　so　quiet；　so　composed
  and　gentle　in　all　his　actions；　that　at　times　I　should　have　been
  almost　inclined　to　call　him　effeminate。　We　had　a　long　talk
  together　on　the　first　evening　of　our　meeting；　we　often　saw　each
  other　afterward；　and　never　lost　a　single　opportunity　of　bettering
  our　acquaintance。　I　felt　that　he　had　taken　a　liking　to　me；　and；
  in　spite　of　what　I　had　heard　about　his　behavior　to　Miss　Elmslie；
  in　spite　of　the　suspicions　which　the　history　of　his　family　and
  his　own　conduct　had　arrayed　against　him；　I　began　to　like　〃Mad
  Monkton〃　as　much　as　he　liked　me。　We　took　many　a　quiet　ride
  together　in　the　country；　and　sailed　often　along　the　shores　of　the
  Bay　on　either　side。　But　for　two　eccentricities　in　his　conduct；
  which　I　could　not　at　all　understand；　I　should　soon　have　felt　as
  much　at　my　ease　in　his　society　as　if　he　had　been　my　own　brother。
  The　first　of　these　eccentricities　consisted　in　the　reappearance
  on　several　occasions　of　the　odd　expression　in　his　eyes　which　I
  had　first　seen　when　he　asked　me　whether　I　knew　anything　about　the
  duel。　No　matter　what　we　were　talking　about；　or　where　we　happened
  to　be；　there　were　times　when　he　would　suddenly　look　away　from　my
  face；　now　on　one　side　of　me；　now　on　the　other；　but　always　where
  there　was　nothing　to　see；　and　always　with　the　same　intensity　and
  fierceness　in　his　eyes。　This　looked　so　like　madnessor
  hypochondria　at　the　leastthat　I　felt　afraid　to　ask　him　about
  it；　and　always　pretended　not　to　observe　him。
  The　second　peculiarity　in　his　conduct　was　that　he　never　referred；
  while　in　my　company；　to　the　reports　about　his　errand　at　Naples；
  and　never　once　spoke　of　Miss　Elmslie；　or　of　his　life　at　Wincot
  Abbey。　This　not　only　astonished　me；　but　amazed　those　who　had
  noticed　our　intimacy；　and　who　had　made　sure　that　I　must　be　the
  depositary　of　all　his　secrets。　But　the　time　was　near　at　hand　when
  this　mystery；　and　some　other　mysteries　of　which　I　had　no
  suspicion　at　that　period；　were　all　to　be　revealed。
  I　met　him　one　night　at　a　large　ball；　given　by　a　Russian　nobleman；
  whose　name　I　could　not　pronounce　then；　and　cannot　remember　now。　I
  had　wandered　away　from　reception…room；　ballroom；　and　cardroom；　to
  a　small　apartment　at　one　extremity　of　the　palace；　which　was　half
  conservatory；　half　boudoir；　and　which　had　been　prettily
  illuminated　for　the　occasion　with　Chinese　lanterns。　Nobody　was　in
  the　room　when　I　got　there。　The　view　over　the　Mediterranean；
  bathed　in　the　bright　softness　of　Italian　moonlight；　was　so　lovely
  that　I　remained　for　a　long　time　at　the　window；　looking　out；　and
  listening　to　the　dance…music　which　faintly　reached　me　from　the
  ballroom。　My　thoughts　were　far　away　with　the　relations　I　had　left
  in　England；　when　I　was　startled　out　of　them　by　hearing　my　name
  softly　pronounced。
  I　looked　round　directly；　and　saw　Monkton　standing　in　the　room。　A
  livid　paleness　overspread　his　face；　and　his　eyes　were　turned　away
  from　me　with　the　same　extraordinary　expression　in　them　to　which　I
  have　already　alluded。
  〃Do　you　mind　leaving　the　ball　early　to…night？〃　he　asked；　still
  not　looking　at　me。
  〃Not　at　all；〃　said　I。　〃Can　I　do　anything　for　you？　Are　you　ill？〃
  〃Noat　least　nothing　to　speak　of。　Will　you　come　to　my　rooms？〃
  〃At　once；　if　you　like。〃
  〃No；　not　at　once。　_I_　must　go　home　directly；　but　don't　you　come
  to　me　for　half　an　hour　yet。　You　have　not　been　at　my　rooms　before；
  I　know；　but　you　will　easily　find　them　out；　they　are　close　by。
  There　is　a　card　with　my　address。　I　_must_　speak　to　you　to…night；
  my　life　depends　on　it。　Pray　come！　for　God's　sake；　come　when　the
  half　hour　is　up！〃
  I　promised　to　be　punctual；　and　he　left　me　directly。
  Most　people　will　be　easily　able　to　imagine　the　state　of　nervous
  impatience　and　vague　expectation　in　which　I　passed　the　allotted
  period　of　delay；　after　hearing　such　words　as　those　Monkton　had
  spoken　to　me。　Before　the　half　hour　had　quite　expired　I　began　to
  make　my　way　out　through　the　ballroom。
  At　the　head　of　the　staircase　my　friend；　the　_attache；_　met　me。
  〃What！　going　away　already？〃　Said　he。
  〃Yes；　and　on　a　very　curious　expedition。　I　am　going　to　Monkton's
  rooms；　by　his　own　invitation。〃
  〃You　don't　mean　it！　Upon　my　honor；　you're　a　bold　fellow　to　trust
  yourself　alone　with　'Mad　Monkton'　when　the　moon　is　at　the　full。〃
  〃He　is　ill；　poor　fellow。　Besides；　I　don't　think　him　half　as　mad
  as　you　do。〃
  〃We　won't　dispute　about　that；　but　mark　my　words；　he　has　not　asked
  you　to　go　where　no　visitor　has　ever　been　admitted　before　without
  a　special　purpose。　I　predict　that　you　will　see　or　hear　something
  to…night　which　you　will　remember　for　the　rest　of　your　life。〃
  We　parted。　When　I　knocked　at　the　courtyard　gate　of　the　house
  where　Monkton　lived；　my　friend's　last　words　on　the　palace
  staircase　recurred　to　me；　and；　though　I　had　laughed　at　him　when
  he　spoke　them；　I　began　to　suspect　even　then　that　his　prediction
  would　be　fulfilled。
  CHAPTER　III。
  THE　porter　who　let　me　into　the　house　where　Monkton　lived　directed
  me　to　the　floor　on　which　his　rooms　were　situated。　On　getting
  upstairs；　I　found　his　door　on　the　landing　ajar。　He　heard　my
  footsteps；　I　suppose；　for　he　called　to　me　to　come　in　before　I
  could　knock。
  I　entered；　and　found　him　sitting　by　the　table；　with　some　loose
  letters　in　his　hand；　which　he　was　just　tying　together　into　a
  packet。　I　noticed；　as　he　asked　me　to　sit　down；　that　his　express
  ion　looked　more　composed；　though　the　paleness　had　not　yet　left
  his　face。　He　thanked　me　for　coming；　repeated　that　he　had
  something　very　important　to　say　to　me；　and　then　stopped　short；
  apparently　too　much　embarrassed　to　proceed。　I　tried　to　set　him　at
  his　ease　by　assuring　him　that；　if　my　assistance　or　advice　could
  be　of　any　use；　I　was　ready　to　place　myself　and　my　time　heartily
  and　unreservedly　at　his　service。
  As　I　said　this　I　saw　his　eyes　beginning　to　wander　away　from　my
  faceto　wander　slowly；　inch　by　inch；　as　it　were；　until　they
  stopped　at　a　certain　point；　with　the　same　fix
