"'Urry up, Ma!" said Harley, entering without ceremony; "I want to introduce my pal Jim 'ere to old Kwen Lung, and make it all right for him before I sail."

Ma Lorenzo, who was half Portuguese, replied in her peculiar accent:

"This no time to come waking me up out of bed!"

But Harley, brushing past her, was already inside the stuffy little room, and I hastened to follow.

"Kwen Lung!" shouted my friend loudly. "Where are you? Brought a friend to see you."

"Kwen Lung no hab," came the complaining tones of Ma Lorenzo from behind us.

It was curious to note how long association with the Chinese had resulted in her catching the infection of that pidgin-English which is a sort of esperanto in all Asiatic quarters.

"Eh!" cried my friend, pushing open a door on the right of the passage and stumbling down three worn steps into a very evil- smelling room. "Where is he?"

"Go play fan-tan. Not come back."

Ma Lorenzo, having relocked the street door, had rejoined us, and as I followed my friend down into the dim and uninviting apartment she stood at the top of the steps, hands on hips, regarding us.

The place, which was quite palpably an opium den, must have disappointed anyone familiar with the more ornate houses of Chinese vice in San Francisco and elsewhere. The bare floor was not particularly clean, and the few decorations which the room boasted were garishly European for the most part. A deep divan, evidently used sometimes as a bed, occupied one side of the room, and just to the left of the steps reposed the only typically Oriental object in the place. It was a strange thing to see in so sordid a setting; a great gilded joss, more than life-size, squatting, hideous, upon a massive pedestal; a figure fit for some native temple but strangely out of place in that dirty little Limehouse abode.

I had never before visited Kwen Lung's, but the fame of his golden joss had reached me, and I know that he had received many offers for it, all of which he had rejected. It was whispered that Kwen Lung was rich, that he was a great man among the Chinese, and even that some kind of religious ceremony periodically took place in his house. Now, as I stood staring at the famous idol, I saw something which made me stare harder than ever.

The place was lighted by a hanging lamp from which depended bits of coloured paper and several gilded silk tassels; but dim as the light was it could not conceal those tell-tale stains.

There was blood on the feet of the golden idol!

All this I detected at a glance, but ere I had time to speak:

"You can't tell me that tale, Ma!" cried Harley. "I believe 'e was smokin' in 'ere when we knocked."

The woman shrugged her fat shoulders.

"No, hab," she repeated. "You two johnnies clear out. Let me sleep."

But as I turned to her, beneath the nonchalant manner I could detect a great uneasiness; and in her dark eyes there was fear. That Harley also had seen the bloodstains I was well aware, and I did not doubt that furthermore he had noted the fact that the only mat which the room boasted had been placed before the joss- doubtless to hide other stains upon the boards.

As we stood so I presently became aware of a current of air passing across the room in the direction of the open door. It came from a window before which a tawdry red curtain had been draped. Either the window behind the curtain was wide open, which is alien to Chinese habits, or it was shattered. While I was wondering if Harley intended to investigate further:

"Come on, Jim!" he cried boisterously, and clapped me on the shoulder; "the old fox don't want to be disturbed."

He turned to the woman:

"Tell him when he wakes up, Ma," he said, "that if ever my pal Jim wants a pipe he's to 'ave one. Savvy? Jim's square."

"Savvy," replied the woman, and she was wholly unable to conceal her relief. "You clear out now, and I tell Kwen Lung when he come in."

"Righto, Ma!" said Harley. "Kiss 'im on both cheeks for me, an' tell 'im I'll be 'ome again in a month."

Grasping me by the arm he lurched up the steps, and the two of us presently found ourselves out in the street again. In the growing light the squalor of the district was more evident than ever, but the comparative freshness of the air was welcome after the reek of that room in which the golden idol sat leering, with blood at his feet.

"You saw, Harley?" I exclaimed excitedly. "You saw the stains? And I'm certain the window was broken!"

Harley nodded shortly.

"Back to Wade Street!" he said. "I allow myself fifteen minutes to shed Bill Jones, able seaman, and to become Paul Harley, of Chancery Lane."

As we hurried along:

"What steps shall you take?" I asked.

"First step: search Kwen Lung's house from cellar to roof. Second step: entirely dependent upon result of first. The Chinese are subtle, Knox. If Kwen Lung has killed his daughter, it may require all the resources of Scotland Yard to prove it."

"But--"

"There is no 'but' about it. Chinatown is the one district of London which possesses the property of swallowing people up."

III. "CAPTAIN DAN"

Half an hour later, as I sat in the inner room before the great dressing-table laboriously removing my disguise-for I was utterly incapable of metamorphosing myself like Harley in seven minutes-I heard a rapping at the outer door. I glanced nervously at my face in the mirror.

Comparatively little of "Jim" had yet been removed, for since time was precious to my friend I had acted as his dresser before setting to work to remove my own make-up. There were two entrances to the establishment, by one of which Paul Harley invariably entered and invariably went out, and from the other of which "Bill Jones" was sometimes seen to emerge, but never Paul Harley. That my friend had made good his retirement I knew, but, nevertheless, if I had to open the door of the outer room it must be as "Jim."

Thinking it impolite not to do so, since the one who knocked might be aware that we had come in but not gone out again, I hastily readjusted that side of my moustache which I had begun to remove, replaced my cap and muffler, and carefully locking the door of the dressing-room, crossed the outer apartment and opened the door.

It was Harley's custom never to enter or leave these rooms except under the mantle of friendly night, but at so early an hour I confess I had not expected a visitor. Wondering whom I should find there I opened the door.

Standing on the landing was a fellow-lodger who permanently occupied the two top rooms of the house. Paul Harley had taken the trouble to investigate the man's past, for "Captain Dan," the name by which he was known in the saloons and worse resorts which he frequented, was palpably a broken-down gentleman; a piece of flotsam caught in the yellow stream. Opium had been his downfall. How he lived I never knew, but Harley believed he had some small but settled income, sufficient to enable him to kill himself in comfort with the black pills.

As he stood there before me in the early morning light, I was aware of some subtle change in his appearance. It was fully six months since I had seen him last, but in some vague way he looked younger. Haggard he was, with an ugly cut showing on his temple, but not so lined as I remembered him. Some former man seemed to be struggling through the opium-scarred surface. His eyes were brighter, and I noted with surprise that he wore decent clothes and was clean shaved.

"Good morning, Jim," he said; "you remember me, don't you?"

As he spoke I observed, too, that his manner had altered. He who had consorted with the sweepings af the doss-houses now addressed me as a courteous gentleman addresses an inferior-not haughtily or patronizingly, but with a note of conscious superiority and self-respect wholly unfamiliar. Almost it threw me off my guard, but remembering in the nick of time that I was still "Jim":
