banister；　she　staggered　as　she　caught　at　it；　and　held　herself　up。
  The　silence　was　still　unbroken。　Something　in　me；　stronger　than
  myself；　drew　my　steps　along　the　hall　nearer　and　nearer　to　the
  stair；　till　I　could　see　the　face　which　had　struck　that　murderous
  wretch　with　terror。
  I　looked。
  No！　it　was　not　my　sweet　girl；　it　was　a　horrid　transformation　of
  her。　I　saw　a　fearful　creature；　with　glittering　eyes　that
  threatened　some　unimaginable　vengeance。　Her　lips　were　drawn　back；
  they　showed　her　clinched　teeth。　A　burning　red　flush　dyed　her
  face。　The　hair　of　her　head　rose；　little　by　little；　slowly。　And；
  most　dreadful　sight　of　all；　she　seemed；　in　the　stillness　of　the
  house；　to　be　_listening　to　something。_　If　I　could　have　moved；　I
  should　have　fled　to　the　first　place　of　refuge　I　could　find。　If　I
  could　have　raised　my　voice；　I　should　have　cried　for　help。　I　could
  do　neither　the　one　nor　the　other。　I　could　only　look；　look；　look；
  held　by　the　horror　of　it　with　a　hand　of　iron。
  Helena　must　have　roused　her　courage；　and　resisted　her　terror。　I
  heard　her　speak：
  〃Let　me　by！〃
  〃No。〃
  Slowly；　steadily；　in　a　whisper；　Euneece　made　that　reply。
  Helena　tried　once　morestill　fighting　against　her　own　terror：　I
  knew　it　by　the　trembling　of　her　voice。
  〃Let　me　by；〃　she　repeated；　〃I　am　on　my　way　to　Philip's　room。〃
  〃You　will　never　enter　Philip's　room　again。〃
  〃Who　will　stop　me？〃
  〃I　will。〃
  She　had　spoken　in　the　same　steady　whisper　throughoutbut　now　she
  moved。　I　saw　her　set　her　foot　on　the　first　stair。　I　saw　the
  horrid　glitter　in　her　eyes　flash　close　into　Helena's　face。　I
  heard　her　say：
  〃Poisoner；　go　back　to　your　room。〃
  Silent　and　shuddering；　Helena　shrank　away　from　herdaunted　by
  her　glittering　eyes；　mastered　by　her　lifted　hand　pointing　up　the
  stairs。
  Helena　slowly　ascended　till　she　reached　the　landing。　She　turned
  and　looked　down；　she　tried　to　speak。　The　pointing　hand　struck　her
  dumb；　and　drove　her　up　the　next　flight　of　stairs。　She　was　lost　to
  view。　Only　the　small　rustling　sound　of　the　dress　was　to　be　heard；
  growing　fainter　and　fainter；　then　an　interval　of　stillness；　then
  the　noise　of　a　door　opened　and　closed　again；　then　no　sound
  morebut　a　change　to　be　seen：　the　transformed　creature　was　cr
  ouching　on　her　knees；　still　and　silent；　her　face　covered　by　her
  hands。　I　was　afraid　to　approach　her；　I　was　afraid　to　speak　to
  her。　After　a　time；　she　rose。　Suddenly；　swiftly；　with　her　head
  turned　away　from　me；　she　opened　the　door　of　Philip's　roomand
  was　gone。
  I　looked　round。　There　was　only　Maria　in　the　lonely　hall。　Shall　I
  try　to　tell　you　what　my　sensations　were？　It　may　sound　strangely；
  but　it　is　trueI　felt　like　a　sleeper；　who　has　half…awakened　from
  a　dream。
  CHAPTER　LX。
  DISCOVERY。
  A　LITTLE　later；　on　that　eventful　day；　when　I　was　most　in　need　of
  all　that　your　wisdom　and　kindness　could　do　to　guide　me；　came　the
  telegram　which　announced　that　you　were　helpless　under　an　attack
  of　gout。　As　soon　as　I　had　in　some　degree　got　over　my
  disappointment；　I　remembered　having　told　Euneece　in　my　letter
  that　I　expected　her　kind　old　friend　to　come　to　us。　With　the
  telegram　in　my　hand　I　knocked　softly　at　Philip's　door。
  The　voice　that　bade　me　come　in　was　the　gentle　voice　that　I　knew
  so　well。　Philip　was　sleeping。　There；　by　his　bedside；　with　his
  hand　resting　in　her　hand；　was　Euneece；　so　completely　restored　to
  her　own　sweet　self　that　I　could　hardly　believe　what　I　had　seen；
  not　an　hour　since。　She　talked　of　you；　when　I　showed　her　your
  message；　with　affectionate　interest　and　regret。　Look　back；　my
  admirable　friend；　at　what　I　have　written　on　the　two　or　three
  pages　which　precede　this；　and　explain　the　astounding　contrast　if
  you　can。
  I　was　left　alone　to　watch　by　Philip；　while　Euneece　went　away　to
  see　her　father。　Soon　afterward；　Maria　took　my　place；　I　had　been
  sent　for　to　the　next　room　to　receive　the　doctor。
  He　looked　care…worn　and　grieved。　I　said　I　was　afraid　he　had
  brought　bad　news　with　him。
  〃The　worst　possible　news；〃　he　answered。　〃A　terrible　exposure
  threatens　this　family；　and　I　am　powerless　to　prevent　it；〃
  He　then　asked　me　to　remember　the　day　when　I　had　been　surprised　by
  the　singular　questions　which　he　had　put　to　me；　and　when　he　had
  engaged　to　explain　himself　after　he　had　made　some　inquiries。　Why；
  and　how；　he　had　set　those　inquiries　on　foot　was　what　he　had　now
  to　tell。　I　will　repeat　what　he　said；　in　his　own　words；　as　nearly
  as　I　can　remember　them。　While　he　was　in　attendance　on　Philip；　he
  had　observed　symptoms　which　made　him　suspect　that　Digitalis　had
  been　given　to　the　young　man；　in　doses　often　repeated。　Cases　of
  attempted　poisoning　by　this　medicine　were　so　rare；　that　he　felt
  bound　to　put　his　suspicions　to　the　test　by　going　round　among　the
  chemists's　shopsexcepting　of　course　the　shop　at　which　his　own
  prescriptions　were　made　upand　asking　if　they　had　lately
  dispensed　any　preparation　of　Digitalis；　ordered　perhaps　in　a
  larger　quantity　than　usual。　At　the　second　shop　he　visited；　the
  chemist　laughed。　〃Why；　doctor；〃　he　said；　〃have　you　forgotten　your
  own　prescription？〃　After　this；　the　prescription　was　asked　for；
  and　produced。　It　was　on　the　paper　used　by　the　doctorpaper　which
  had　his　address　printed　at　the　top；　and　a　notice　added；　telling
  patients　who　came　to　consult　him　for　the　second　time　to　bring
  their　prescriptions　with　them。　Then；　there　followed　in　writing：
  〃Tincture　of　Digitalis；　one　ounce〃with　his　signature　at　the
  end；　not　badly　imitated；　but　a　forgery　nevertheless。　The　chemist
  noticed　the　effect　which　this　discovery　had　produced　on　the
  doctor；　and　asked　if　that　was　his　signature。　He　could　hardly；　as
  an　honest　man；　have　asserted　that　a　forgery　was　a　signature　of
  his　own　writing。　So　he　made　the　true　reply；　and　asked　who　had
  presented　the　prescription。　The　chemist　called　to　his　assistant
  to　come　forward。　〃Did　you　tell　me　that　you　knew；　by　sight；　the
  young　lady　who　brought　this　prescription？〃　The　assistant　admitted
  it。　〃Did　you　tell　me　she　was　Miss　Helena　Gracedieu？〃　〃I　did。〃
  〃Are　you　sure　of　not　having　made　any　mistake？〃　〃Quite　sure。〃　The
  chemist　then　said：　〃I　myself　supplied　the　Tincture　of　Digitalis；
  and　the　young　lady　paid　for　it；　and　took　it　away　with　her。　You
  have　had　all　the　information　that　I　can　give　you；　sir；　and　I　may
  now　ask；　if　you　can　throw　any　light　on　the　matter。〃　Our　good
  friend　thought　of　the　poor　Minister；　so　sorely　afflicted；　and　of
  the　famous　name　so　sincerely　respected　in　the　town　and　in　the
  country　round；　and　said　he　could　not　undertake　to　give　an
  immediate　answer。　The　chemist　was　excessively　angry。　〃You　know　as
  well　as　I　do；〃　he　said；　〃that　Digitalis；　given　in　certain　doses；
  is　a　poison；　and　you　cannot　deny　that　I　honestly　believed　myself
  to　be　dispensing　your　prescription。　While　you　are　hesitating　to
  give　me　an　answer；　my　character　may　suffer；　I　may　be　suspected
  myself。〃　He　ended　in　declaring　he　should　consult　his　lawyer。　The
  doctor　went　home；　and　questioned　his　servant。　The　man　remembered
  the　day　of　Miss　Helena's　visit　in　the　afternoon；　and　the
  intention　that　she　expressed　of　waiting　for　his　master's　return。
  He　had　shown　her　into　the　parlor　which　opened　into　the
  consulting…room。　No　other　visitor　was　in　the　house　at　that　time；
  or　had　arrived　during　the　rest　of　the　day。　The　doctor's　own
  experience；　when　he　got　home；　led　him　to　conclude　that　Helena　had
  gone　into　the　consulting…room。　He　had　entered　that　room；　for　the
  purpose　of　writing　some　prescriptions；　and　had　found　the　leaves
  of　paper　that　he　used　diminished　in　number。　After　what　he　had
  heard；　and　what　he　had　discovered　（to　say　nothing　of　what　he
  suspected）；　it　occurred　to　him　to　look　along　the　shelves　of　his
  medical　library。　He　found　a　volume　（treating　of　Poisons）　with　a
  slip　of　paper　left　between　the　leaves；　the　poison　described　at
  the　place　so　marked　being　Digitalis；　and　the　paper　used　being　one
  of　his　own　prescription…papers。　〃If；　as　I　fear；　a　legal
  investigation　into　Helena's　conduct　is　a　possible　event；〃　the
  doctor　concluded；　〃there　is　the　evidence　that　I　shall　be　obliged
  to　give；　when　I　am　called　as　a　witness。〃
  It　is　my　belief　that　I　could　have　felt　no　greater　dismay；　if　the
  long　arm　of　the　Law　had　laid　its　hold　on　me　while　he　was
  speaking。　I　asked　what　was　to　be　done。
  〃If　she　leaves　the　house　at　once；〃　the　doctor　replied；　〃she　may
  escape　the　infamy　of　being　charged　with　an　attempt　at　murder　by
  poison；　and；　in　her　absence；　I　can　answer　for　Philip's　life。　I
  don't　urge　you　to　warn　her；　because　that　might　be　a　dangerous
  thing　to　do。　It　is　for　you　to　decide；　as　a　member　of　the　family；
  whether　you　will　run　the　risk。〃
  I　tried　to　speak　to　him　of　Euneece；　and　to　tell　him　what　I　had
  already　related　to　yourself。　He　was　in　no　humor　to　listen　to　me。
  〃Keep　it　for　a　fitter　time；〃　he　answered；　〃and　think　of　what　I
  have　just　said　to　you。〃　With　that；　he　left　me；　on　his　way　to
  Philip's　room。
  Mental　exertion　was　completely　beyond　me。　Can　you　understand　a
  poor　middle…aged　spinster　being　frightened　into　doing　a　dangerous
  thing？　That　may　seem　to　be　nonsense。　But　if　you　ask　why　I　took　a
  morsel　of　paper；　and　wrote　the　warning　which　I　was　afraid　to
  communicate　by　word　of　mouthwhy　I　went　upstairs　with　my　knees
  knocking　together；　and　opened　the　door　of　Helena's　room　just
