〃Did　you？〃　said　Mr。　Hoopdriver；　quite　at　sea；　but　rising　pluckily　to　the　unknown　occasion。　What　was　the　man　driving　at？
  〃I　see；〃　said　the　other　man。　〃I　see。　I　half　suspected〃　His　manner　changed　abruptly　to　a　quality　suspiciously　friendly。　〃Yes…　…a　word　with　you。　You　will；　I　hope；　give　me　ten　minutes。〃
  Wonderful　things　were　dawning　on　Mr。　Hoopdriver。　What　did　the　other　man　take　him　for？　Here　at　last　was　reality！　He　hesitated。　Then　he　thought　of　an　admirable　phrase。　〃You　'ave　some　communication〃
  〃We'll　call　it　a　communication；〃　said　the　other　man。
  〃I　can　spare　you　the　ten　minutes；〃　said　Mr。　Hoopdriver；　with　dignity。
  〃This　way；　then；〃　said　the　other　man　in　brown；　and　they　walked　slowly　down　the　North　Street　towards　the　Grammar　School。　There　was；　perhaps；　thirty　seconds'　silence。　The　other　man　stroked　his　moustache　nervously。　Mr。　Hoopdriver's　dramatic　instincts　were　now　fully　awake。　He　did　not　quite　understand　in　what　role　he　was　cast；　but　it　was　evidently　something　dark　and　mysterious。　Doctor　Conan　Doyle；　Victor　Hugo；　and　Alexander　Dumas　were　well　within　Mr。　Hoopdriver's　range　of　reading；　and　he　had　not　read　them　for　nothing。
  〃I　will　be　perfectly　frank　with　you；〃　said　the　other　man　in　brown。
  〃Frankness　is　always　the　best　course；〃　said　Mr。　Hoopdriver。
  〃Well；　thenwho　the　devil　set　you　on　this　business？〃
  〃Set　me　ON　this　business？〃
  〃Don't　pretend　to　be　stupid。　Who's　your　employer？　Who　engaged　you　for　this　job？〃
  〃Well；〃　said　Mr。　Hoopdriver；　confused。　〃NoI　can't　say。〃
  〃Quite　sure？〃　The　other　man　in　brown　glanced　meaningly　down　at　his　hand；　and　Mr。　Hoopdriver；　following　him　mechanically；　saw　a　yellow　milled　edge　glittering　in　the　twilight。　Now　your　shop　assistant　is　just　above　the　tip…receiving　class；　and　only　just　above　itso　that　he　is　acutely　sensitive　on　the　point。
  Mr。　Hoopdriver　flushed　hotly；　and　his　eyes　were　angry　as　he　met　those　of　the　other　man　in　brown。　〃Stow　it！〃　said　Mr。　Hoopdriver；　stopping　and　facing　the　tempter。
  〃What！〃　said　the　other　man　in　brown；　surprised。　〃Eigh？〃　And　so　saying　he　stowed　it　in　his　breeches　pocket。
  〃D'yer　think　I'm　to　be　bribed？〃　said　Mr。　Hoopdriver；　whose　imagination　was　rapidly　expanding　the　situation。　〃By　Gosh！　I'd　follow　you　now〃
  〃My　dear　sir；〃　said　the　other　man　in　brown；　〃I　beg　your　pardon。　I　misunderstood　you。　I　really　beg　your　pardon。　Let　us　walk　on。　In　your　profession〃
  〃What　have　you　got　to　say　against　my　profession？〃
  〃Well；　really；　you　know。　There　are　detectives　of　an　inferior　descriptionwatchers。　The　whole　class。　Private　InquiryI　did　not　realiseI　really　trust　you　will　overlook　what　was；　after　allyou　must　admita　natural　indiscretion。　Men　of　honour　are　not　so　common　in　the　worldin　any　profession。〃
  It　was　lucky　for　Mr。　Hoopdriver　that　in　Midhurst　they　do　not　light　the　lamps　in　the　summer　time；　or　the　one　they　were　passing　had　betrayed　him。　As　it　was；　he　had　to　snatch　suddenly　at　his　moustache　and　tug　fiercely　at　it；　to　conceal　the　furious　tumult　of　exultation；　the　passion　of　laughter；　that　came　boiling　up。　Detective！　Even　in　the　shadow　Bechamel　saw　that　a　laugh　was　stifled；　but　he　put　it　down　to　the　fact　that　the　phrase　〃men　of　honour〃　amused　his　interlocutor。　〃He'll　come　round　yet；〃　said　Bechamel　to　himself。　〃He's　simply　holding　out　for　a　fiver。〃　He　coughed。
  〃I　don't　see　that　it　hurts　you　to　tell　me　who　your　employer　is。〃
  〃Don't　you？　I　do。〃
  〃Prompt；〃　said　Bechamel；　appreciatively。　〃Now　here's　the　thing　I　want　to　put　to　youthe　kernel　of　the　whole　business。　You　need　not　answer　if　you　don't　want　to。　There's　no　harm　done　in　my　telling　you　what　I　want　to　know。　Are　you　employed　to　watch　meor　Miss　Milton？〃
  〃I'm　not　the　leaky　sort；〃　said　Mr。　Hoopdriver；　keeping　the　secret　he　did　not　know　with　immense　enjoyment。　Miss　Milton！　That　was　her　name。　Perhaps　he'd　tell　some　more。　〃It's　no　good　pumping。　Is　that　all　you're　after？〃　said　Mr。　Hoopdriver。
  Bechamel　respected　himself　for　his　diplomatic　gifts。　He　tried　to　catch　a　remark　by　throwing　out　a　confidence。　〃I　take　it　there　are　two　people　concerned　in　watching　this　affair。〃
  〃Who's　the　other？〃　said　Mr。　Hoopdriver；　calmly；　but　controlling　with　enormous　internal　tension　his　selfappreciation。　〃Who's　the　other？〃　was　really　brilliant；　he　thought。
  〃There's　my　wife　and　HER　stepmother。〃
  〃And　you　want　to　know　which　it　is？〃
  〃Yes；〃　said　Bechamel。
  〃Wellarst　'em！〃　said　Mr。　Hoopdriver；　his　exultation　getting　the　better　of　him；　and　with　a　pretty　consciousness　of　repartee。　〃Arst　'em　both。〃
  Bechamel　turned　impatiently。　Then　he　made　a　last　effort。　〃I'd　give　a　five…pound　note　to　know　just　the　precise　state　of　affairs；〃　he　said。
  〃I　told　you　to　stow　that；〃　said　Mr。　Hoopdriver；　in　a　threatening　tone。　And　added　with　perfect　truth　and　a　magnificent　mystery；　〃You　don't　quite　understand　who　you're　dealing　with。　But　you　will！〃　He　spoke　with　such　conviction　that　he　half　believed　that　that　defective　office　of　his　in　LondonBaker　Street；　in　fact　really　existed。
  With　that　the　interview　terminated。　Bechamel　went　back　to　the　Angel；　perturbed。　〃Hang　detectives！〃　It　wasn't　the　kind　of　thing　he　had　anticipated　at　all。　Hoopdriver；　with　round　eyes　and　a　wondering　smile；　walked　down　to　where　the　mill　waters　glittered　in　the　moonlight；　and　after　meditating　over　the　parapet　of　the　bridge　for　a　space；　with　occasional　murmurs　of；　〃Private　Inquiry〃　and　the　like；　returned；　with　mystery　even　in　his　paces；　towards　the　town。

  That　glee　which　finds　expression　in　raised　eyebrows　and　long；　low　whistling　noises　was　upon　Mr。　Hoopdriver。　For　a　space　he　forgot　the　tears　of　the　Young　Lady　in　Grey。　Here　was　a　new　game！and　a　real　one。　Mr。　Hoopdriver　as　a　Private　Inquiry　Agent；　a　Sherlock　Holmes　in　fact；　keeping　these　two　people　'under　observation。'　He　walked　slowly　back　from　the　bridge　until　he　was　opposite　the　Angel；　and　stood　for　ten　minutes；　perhaps；　contemplating　that　establishment　and　enjoying　all　the　strange　sensations　of　being　this　wonderful；　this　mysterious　and　terrible　thing。　Everything　fell　into　place　in　his　scheme。　He　had；　of　course；　by　a　kind　of　instinct；　assumed　the　disguise　of　a　cyclist；　picked　up　the　first　old　crock　he　came　across　as　a　means　of　pursuit。　'No　expense　was　to　be　spared。'
  Then　he　tried　to　understand　what　it　was　in　particular　that　he　was　observing。　〃My　wife〃〃HER　stepmother！〃　Then　he　remembered　her　swimming　eyes。　Abruptly　came　a　wave　of　anger　that　surprised　him；　washed　away　the　detective　superstructure；　and　left　him　plain　Mr。　Hoopdriver。　This　man　in　brown；　with　his　confident　manner；　and　his　proffered　half　sovereign　（damn　him！）　was　up　to　no　good；　else　why　should　he　object　to　being　watched？　He　was　married！　She　was　not　his　sister。　He　began　to　understand。　A　horrible　suspicion　of　the　state　of　affairs　came　into　Mr。　Hoopdriver's　head。　Surely　it　had　not　come　to　THAT。　He　was　a　detective！he　would　find　out。　How　was　it　to　be　done？　He　began　to　submit　sketches　on　approval　to　himself。　It　required　an　effort　before　he　could　walk　into　the　Angel　bar。　〃A　lemonade　and　bitter；　please；〃　said　Mr。　Hoopdriver。
  He　cleared　his　throat。　〃Are　Mr。　and　Mrs。　Bowlong　stopping　here？〃
  〃What；　a　gentleman　and　a　young　ladyon　bicycles？〃
  〃Fairly　younga　married　couple。〃
  〃No；〃　said　the　barmaid；　a　talkative　person　of　ample　dimensions。　〃There's　no　married　couples　stopping　here。　But　there's　a　Mr。　and　Miss　BEAUMONT。〃　She　spelt　it　for　precision。　〃Sure　you've　got　the　name　right；　young　man？〃
  〃Quite；〃　said　Mr。　Hoopdriver。

  〃Bowlong；〃　said　Mr。　Hoopdriver。
  〃No；　there　ain't　no　Bowlong；〃　said　the　barmaid；　taking　up　a　glasscloth　and　a　drying　tumbler　and　beginning　to　polish　the　latter。　〃First　off；　I　thought　you　might　be　asking　for　Beaumont　the　names　being　similar。　Were　you　expecting　them　on　bicycles？〃
  〃Yesthey　said　they　MIGHT　be　in　Midhurst　tonight。〃

  〃Certain；〃　said　Mr。　Hoopdriver。
  〃It's　curious　the　names　being　so　alike。　I　thought　p'raps〃
  And　so　they　conversed　at　some　length；　Mr。　Hoopdriver　delighted　to　find　his　horrible　suspicion　disposed　of。　The　barmaid　having　listened　awhile　at　the　staircase　volunteered　some　particulars　of　the　young　couple　upstairs。　Her　modesty　was　much　impressed　by　the　young　lady's　costume；　so　she　intimated；　and　Mr。　Hoopdriver　whispered　the　badinage　natural　to　the　occasion；　at　which　she　was　coquettishly　shocked。　〃There'll　be　no　knowing　which　is　which；　in　a　year　or　two；〃　said　the　barmaid。　〃And　her　manner　too！　She　got　off　her　machine　and　give　it　'im　to　stick　up　against　the　kerb；　and　in　she　marched。　'I　and　my　brother；'　says　she；　'want　to　stop　here　to…night。　My　brother　doesn't　mind　what　kind　of　room　'e　'as；　but　I　want　a　room　with　a　good　view；　if　there's　one　to　be　got；'　says　she。　He　comes　hurrying　in　after　and　looks　at　her。　'I've　settled　the　rooms；'　she　says；　and　'e　says　'damn！'　just　like　that。　I　can　fancy　my　brother　letting　me　boss　the　show　like　that。〃
