Chan bowed with a great show of politeness。 He launched into a long story in Chinese。 Lau Ho looked at him with slight interest。 Presently he squeaked a brief reply。 Chan resumed his flow of talk。 Occasionally he paused； and Lau Ho spoke。 In a few moments Chan turned beaming。
〃Story are now pletely extracted like aching tooth；〃 he said。 〃Wrist watch was brought to Lau Ho on Thursday； same week as murder。 Offered him on sale by young man darkly colored with small knife scar marring cheek。 Lau Ho buy and repair watch； interior works being in injured state。 Saturday morning he sell at seemly profit to Japanese； presumably this Okoda here but Lau Ho will not swear。 Saturday night dark young man appear much overwhelmed with excitement and demand watch again； please。 Lau Ho say it is sold to Japanese。 Which Japanese？ Lau Ho is not aware of name； and can not describe； all Japanese faces being uninteresting outlook for him。 Dark young man curse and fly。 Appear frequently demanding any news； but Lau Ho is unable to oblige。 Such are story of this jewel merchant here。〃
They went out on the street。 Hallet scowled at the Japanese man。 〃All right … run along。 I'll keep the watch。〃
〃Very thankful；〃 said the taxi driver； and leaped into his car。
Hallet turned to Chan。 〃A dark young man with a scar？〃 he queried。
〃Clear enough to me；〃 Chan answered。 〃Same are the Spaniard Jose Cabrera； careless man about town with reputation not so savory。 Mr。 Winterslip； is it that you have forgotten him？〃
John Quincy started。 〃Me？ Did I ever see him？〃
〃Recall；〃 said Chan。 〃It are the night following murder。 You and I linger in All American Restaurant engaged in debate regarding hygiene of pie。 Door open； admitting Bowker； steward on President Tyler； joyously full of okolehau。 With him are dark young man … this Jose Cabrera himself。〃
〃Oh； I remember now；〃 John Quincy answered。
〃Well； the Spaniard's easy to pick up；〃 said Hallet。 〃I'll have him inside an hour …〃
〃One moment； please；〃 interposed Chan。 〃To…morrow morning at nine o'clock the President Tyler return from Orient。 No gambler myself but will wager increditable sum Spaniard waits on dock for Mr。 Bowker。 If you present no fierce objection； I have a yearning to arrest him at that very moment。〃
〃Why； of course；〃 agreed Hallet。 He looked keenly at Charlie Chan。 〃Charlie； you old rascal； you've got the scent at last。〃
〃Who … me？〃 grinned Chan。 〃With your gracious permission I would alter the picture。 Stone walls are crumbling now like dust。 Through many loopholes light stream in like rosy streaks of dawn。〃
CHAPTER XXI
The Stone Walls Crumble
THE STONE WALLS were crumbling and the light streaming through … but only for Chan。 John Quincy was still groping in the dark； and his reflections were a little bitter as he returned to the house at Waikiki。 Chan and he had worked together； but now that they approached the crisis of their efforts； the detective evidently preferred to push on alone； leaving his fellow…worker to follow if he could。 Well； so be it … but John Quincy's pride was touched。
He had suddenly a keen desire to show Chan that he could not be left behind like that。 If only he could； by some inspirational flash of deductive reasoning； arrive at the solution of the mystery simultaneously with the detective。 For the honor of Boston and the Winterslips。
Frowning deeply； he considered all the old discarded clues again。 The people who had been under suspicion and then dropped … Egan； the pton woman； Brade； Kaohla； Leatherbee； Saladine； Cope。 He even considered several the investigation had not touched。 Presently he came to Bowker。 What did Bowker's reappearance mean？
For the first time in two weeks he thought of the little…man with the fierce pompadour and the gold…rimmed eyeglasses。 Bowker with his sorrowful talk of vanished bar…rooms and lost friends behind the bar。 How was the steward on the President Tyler connected with the murder of Dan Winterslip？ He had not done it himself； that was obvious； but in some way he was linked up with the crime。 John Quincy spent a long and painful period seeking to join Bowker up with one or another of the suspects。 It couldn't be done。
All through that Tuesday evening the boy puzzled； so silent and distrait that Miss Minerva finally gave him up and retired to her room with a book。 He awoke on Wednesday morning with the problem no nearer solution。
Barbara was due to arrive at ten o'clock from Kauai； and taking the small car； John Quincy went down…town to meet her。 Pausing at the bank to cash a check； he encountered his old shipmate on the President Tyler； the sprightly Madame Maynard。
〃I really shouldn't speak to you；〃 she said。 〃You never e to see me。〃
〃I know；〃 he answered。 〃But I've been so very busy。〃
〃So I hear。 Running round with policemen and their victims。 I have no doubt you'll go back to Boston and report we're all criminals and cutthroats out here。〃
〃Oh； hardly that。〃
〃Yes； you will。 You're getting a very biased view of Honolulu。 Why not stoop to associate with a respectable person now and then？〃
〃I'd enjoy it … if they're all like you。〃
〃Like me？ They're much more intelligent and charming than I am。 Some of them are dropping in at my house tonight for an informal little party。 A bit of a chat； and then a moonlight swim。 Won't you e too？〃
〃I want to； of course；〃 John Quincy replied。 〃But there's Cousin Dan …〃
Her eyes flashed。 〃I'll say it； even if he was your relative。 Ten minutes of mourning for Cousin Dan is ample。 I'll be looking for you。〃
John Quincy laughed。 〃I'll e。〃
〃Do；〃 she answered。 〃And bring your Aunt Minerva。 Tell her I said she might as well be dead as hog…tied by convention。〃
John Quincy went out to the corner of Fort and King Streets； near which he had parked the car。 As he was about to climb into it； he paused。 A familiar figure was jauntily crossing the street。 The figure of Bowker； the steward； and with him was Willie Chan； demon back…stopper of the Pacific。
〃Hello； Bowker；〃 John Quincy called。
Mr。 Bowker came blithely to join him。 〃Well； well； well。 My old friend Mr。 Winterslip。 Shake hands with William Chan； the local Ty Cobb。〃
〃Mr。 Chan and I have met before；〃 John Quincy told him。
〃Know all the celebrities； eh？ That's good。 Well； we missed you on the President Tyler。〃
Bowker was evidently quite sober。 〃Just got in； I take it；〃 John Quincy remarked。
〃A few minutes ago。 How about joining us？〃 He came closer and lowered his voice。 〃This intelligent young man tells me he knows a taxi stand out near the beach where one may obtain a superior brand of fusel oil with a very pretty label on the bottle。〃
〃Sorry；〃 John Quincy answered。 〃My cousin's ing in shortly on an Inter…Island boat； and I'm elected to meet her。〃
〃I'm sorry； too；〃 said the graduate of Dublin University。 〃If my strength holds out I'm aiming to stage quite a little party； and I'd like to have you in on it。 Yes； a rather large affair … in memory of Tim； and as a last long lingering farewell to the seven seas。〃
〃What？ You're pau？〃
〃Pau it is。 When I sail out of here to…night at nine on the old P。T。 I'm through for ever。 You don't happen to know a good country newspaper that can be bought for … well； say ten grand。〃
〃This is rather sudden； isn't it？〃 John Quincy inquired。
〃This is sudden country out here； sir。 Well； we must roll along。 Sorry you can't join us。 If the going's not too rough and I can find a nice smooth table top； I intend to turn down an empty glass。 For poor old Tim。 So long； sir … and happy days。〃
He nodded to Willie Chan； and they went on down the street。 John Quincy stood staring after them； a puzzled expression on his face。
Barbara seemed paler and thinner than ever； but she announced that her visit had been an enjoyable one； and on the ride to the beach appeared to be making a distinct effort to be gay and sprightly。 When they reached the house； John Quincy repeated to his aunt Mrs。 Maynard's invitation。
〃Better e along；〃 he urged。
〃Perhaps I will；〃 she answered。 〃I'll see。〃
The day passed quietly； and it was not until evening that the monotony was broken。 Leaving the dining…room with his aunt and Barbara； John Q
