morning；　in　which　he　says：
  〃I　think　that　this　case　is　very　much　in　your　line。　We　have　every
  hope　of　clearing　the　matter　up；　but　we　find　a　little　difficulty　in
  getting　anything　to　work　upon。　We　have；　of　course；　wired　to　the
  Belfast　post…office；　but　a　large　number　of　parcels　were　handed　in　upon
  that　day；　and　they　have　no　means　of　identifying　this　particular　one；
  or　of　remembering　the　sender。　The　box　is　a　half…pound　box　of
  honeydew　tobacco　and　does　not　help　us　in　any　way。　The　medical
  student　theory　still　appears　to　me　to　be　the　most　feasible；　but　if　you
  should　have　a　few　hours　to　spare　I　should　be　very　happy　to　see　you　out
  here。　I　shall　be　either　at　the　house　or　in　the　police…station　all　day。
  What　say　you；　Watson？　Can　you　rise　superior　to　the　heat　and　run　down
  to　Croydon　with　me　on　the　off　chance　of　a　case　for　your　annals？〃
  〃I　was　longing　for　something　to　do。〃
  〃You　shall　have　it　then。　Ring　for　our　boots　and　tell　them　to　order　a
  cab。　I'll　be　back　in　a　moment　when　I　have　changed　my　dressing…gown　and
  filled　my　cigar…case。〃
  A　shower　of　rain　fell　while　we　were　in　the　train；　and　the　heat　was
  far　less　oppressive　in　Croydon　than　in　town。　Holmes　had　sent　on　a
  wire；　so　that　Lestrade；　as　wiry；　as　dapper；　and　as　ferret…like　as
  ever；　was　waiting　for　us　at　the　station。　A　walk　of　five　minutes　took
  us　to　Cross　Street；　where　Miss　Cushing　resided。
  It　was　a　very　long　street　of　two…story　brick　houses；　neat　and
  prim；　with　whitened　stone　steps；　and　little　groups　of　aproned　women
  gossiping　at　the　doors。　Halfway　down；　Lestrade　stopped　and　tapped　at　a
  door；　which　was　opened　by　a　small　servant　girl。　Miss　Cushing　was
  sitting　in　the　front　room；　into　which　we　were　ushered。　She　was　a
  placid…faced　woman；　with　large；　gentle　eyes；　and　grizzled　hair　curving
  down　over　her　temples　on　each　side。　A　worked　antimacassar　lay　upon　her
  lap　and　a　basket　of　coloured　silks　stood　upon　a　stool　beside　her。
  〃They　are　in　the　outhouse；　those　dreadful　things；〃　said　she　as
  Lestrade　entered。　I　wish　that　you　would　take　them　away　altogether。〃
  〃So　I　shall；　Miss　Cushing。　I　only　kept　them　here　until　my　friend；
  Mr。　Holmes；　should　have　seen　them　in　your　presence。〃
  〃Why　in　my　presence；　sir？〃
  〃In　case　he　wished　to　ask　any　questions。〃
  〃What　is　the　use　of　asking　me　questions　when　I　tell　you　I　know
  nothing　whatever　about　it？〃
  〃Quite　so；　madam；〃　said　Holmes　in　his　soothing　way。　〃I　have　no　doubt
  that　you　have　been　annoyed　more　than　enough　already　over　this
  business。〃
  〃Indeed；　I　have；　sir。　I　am　a　quiet　woman　and　live　a　retired　life。　It
  is　something　new　for　me　to　see　my　name　in　the　papers　and　to　find　the
  police　in　my　house。　I　won't　have　those　things　in　here；　Mr。　Lestrade。
  If　you　wish　to　see　them　you　must　go　to　the　outhouse。〃
  It　was　a　small　shed　in　the　narrow　garden　which　ran　behind　the　house。
  Lestrade　went　in　and　brought　out　a　yellow　cardboard　box；　with　a
  piece　of　brown　paper　and　some　string。　There　was　a　bench　at　the　end
  of　the　path；　and　we　all　sat　down　while　Holmes　examined；　one　by　one；
  the　articles　which　Lestrade　had　handed　to　him。
  〃The　string　is　exceedingly　interesting；〃　he　remarked；　holding　it
  up　to　the　light　and　sniffing　at　it。　〃What　do　you　make　of　this
  string；　Lestrade？〃
  〃It　has　been　tarred。〃
  〃Precisely。　It　is　a　piece　of　tarred　twine。　You　have　also；　no
  doubt；　remarked　that　Miss　Cushing　has　cut　the　cord　with　a　scissors；　as
  can　be　seen　by　the　double　fray　on　each　side。　This　is　of　importance。〃
  〃I　cannot　see　the　importance；〃　said　Lestrade。
  〃The　importance　lies　in　the　fact　that　the　knot　is　left　intact；　and
  that　this　knot　is　of　a　peculiar　character。〃
  〃It　is　very　neatly　tied。　I　had　already　made　a　note　to　that　effect〃
  said　Lestrade　complacently。
  〃So　much　for　the　string；　then；〃　said　Holmes；　smiling；　〃now　for　the
  box　wrapper。　Brown　paper；　with　a　distinct　smell　of　coffee。　What　did
  you　not　observe　it？　I　think　there　can　be　no　doubt　of　it。　Address
  printed　in　rather　straggling　characters：　'Miss　S。　Cushing；　Cross
  Street；　Croydon。'　Done　with　a　broad…pointed　pen；　probably　a　J　and　with
  very　inferior　ink。　The　word　'Croydon'　has　been　originally　spelled　with
  an　'i；'　which　has　been　changed　to　'y。'　The　parcel　was　directed；
  then；　by　a　man…　the　printing　is　distinctly　masculine…　of　limited
  education　and　unacquainted　with　the　town　of　Croydon。　So　far；　so
  good！　The　box　is　a　yellow；　half…pound　honeydew　box；　with　nothing
  distinctive　save　two　thumb　marks　at　the　left　bottom　corner。　It　is
  filled　with　rough　salt　of　the　quality　used　for　preserving　hides　and
  other　of　the　coarser　commercial　purposes。　And　embedded　in　it　are　these
  very　singular　enclosures。〃
  He　took　out　the　two　ears　as　he　spoke；　and　laying　a　board　across
  his　knee　he　examined　them　minutely；　while　Lestrade　and　I；　bending
  forward　on　each　side　of　him；　glanced　alternately　at　these　dreadful
  relics　and　at　the　thoughtful；　eager　face　of　our　companion。　Finally
  he　returned　them　to　the　box　once　more　and　sat　for　a　while　in　deep
  meditation。
  〃You　have　observed；　of　course；〃　said　he　at　last；　〃that　the　ears
  are　not　a　pair。〃
  〃Yes；　I　have　noticed　that。　But　if　this　were　the　practical　joke　of
  some　students　from　the　dissecting…rooms；　it　would　be　as　easy　for
  them　to　send　two　odd　ears　as　a　pair。
  〃Precisely。　But　this　is　not　a　practical　joke。〃
  〃You　are　sure　of　it？〃
  〃The　presumption　is　strongly　against　it。　Bodies　in　the
  dissecting…rooms　are　injected　with　preservative　fluid。　These　ears　bear
  no　signs　of　this。　They　are　fresh；　too。　They　have　been　cut　off　with　a
  blunt　instrument；　which　would　hardly　happen　if　a　student　had　done
  it。　Again；　carbolic　or　rectified　spirits　would　be　the　preservatives
  which　would　suggest　themselves　to　the　medical　mind；　certainly　not
  rough　salt。　I　repeat　that　there　is　no　practical　joke　here；　but　that　we
  are　investigating　a　serious　crime。〃
  A　vague　thrill　ran　through　me　as　I　listened　to　my　companion's
  words　and　saw　the　stern　gravity　which　had　hardened　his　features。
  This　brutal　preliminary　seemed　to　shadow　forth　some　strange　and
  inexplicable　horror　in　the　background。　Lestrade；　however；　shook　his
  head　like　a　man　who　is　only　half　convinced。
  〃There　are　objections　to　the　joke　theory；　no　doubt〃　said　he；　〃but
  there　are　much　stronger　reasons　against　the　other。　We　know　that　this
  woman　has　led　a　most　quiet　and　respectable　life　at　Penge　and　here
  for　the　last　twenty　years。　She　has　hardly　been　away　from　her　home
  for　a　day　during　that　time。　Why　on　earth；　then；　should　any　criminal
  send　her　the　proofs　of　his　guilt；　especially　as；　unless　she　is　a
  most　consummate　actress；　she　understands　quite　as　little　of　the　matter
  as　we　do？〃
  〃That　is　the　problem　which　we　have　to　solve；〃　Holmes　answered；
  〃and　for　my　part　I　shall　set　about　it　by　presuming　that　my　reasoning
  is　correct　and　that　a　double　murder　has　been　committed。　One　of　these
  ears　is　a　woman's；　small；　finely　formed；　and　pierced　for　an　earring。
  The　other　is　a　man's；　sun…burned；　discoloured；　and　also　pierced　for　an
  earring。　These　two　people　are　presumably　dead；　or　we　should　have　heard
  their　story　before　now。　To…day　is　Friday。　The　packet　was　posted　on
  Thursday　morning。　The　tragedy；　then；　occurred　on　Wednesday　or　Tuesday；
  or　earlier。　If　the　two　people　were　murdered；　who　but　their　murderer
  would　have　sent　this　sign　of　his　work　to　Miss　Cushing？　We　may　take
  it　that　the　sender　of　the　packet　is　the　man　whom　we　want。　But　he
  must　have　some　strong　reason　for　sending　Miss　Cushing　this　packet。
  What　reason　then？　It　must　have　been　to　tell　her　that　the　deed　was
  done！　or　to　pain　her；　perhaps。　But　in　that　case　she　knows　who　it　is。
  Does　she　know？　I　doubt　it。　If　she　knew；　why　should　she　call　the　police
  in？　She　might　have　buried　the　ears；　and　no　one　would　have　been　the
  wiser。　That　is　what　she　would　have　done　if　she　had　wished　to　shield
  the　criminal。　But　if　she　does　not　wish　to　shield　him　she　would　give
  his　name。　There　is　a　tangle　here　which　needs　straightening　out。〃　He
  had　been　talking　in　a　high；　quick　voice；　staring　blankly　up　over　the
  garden　fence；　but　now　he　sprang　briskly　to　his　feet　and　walked　towards
  the　house。
  〃I　have　a　few　questions　to　ask　Miss　Cushing；〃　said　he。
  〃In　that　case　I　may　leave　you　here〃　said　Lestrade；　〃for　I　have
  another　small　business　on　hand。　I　think　that　I　have　nothing　further　to
  learn　from　Miss　Cushing。　You　will　find　me　at　the　police…station。〃
  〃We　shall　look　in　on　our　way　to　the　train；〃　answered　Holmes。　A
  moment　later　he　and　I　were　back　in　the　front　room；　where　the　impassive
  lady　was　still　quietly　working　away　at　her　antimacassar。　She　put　it
  down　on　her　lap　as　we　entered　and　looked　at　us　with　her　frank；
  searching　blue　eyes。
  〃I　am　convinced；　sir；〃　she　said；　〃that　this　matter　is　a　mistake；　and
  that　the　parcel　was　never　meant　for　me　at　all。　I　have　said　this
  several　times　to　the　gentleman　from　Scotland　Yard；　but　he　simply
  laughs　at　me。　I　have　not　an　enemy　in　the　world；　as　far　as　I　know；　so
  why　should　anyone　play　me　such　a　trick？〃
  〃I　am　coming　to　be　of　the　same　opinion；　Miss　Cushing；〃　said
  Holmes；　taking　a　seat　beside　her。　〃I　think　that　it　is　more　than
  probable…〃　he　paused；　and　I　was　surprised；　on　g
