Even in upon my anxiety for my friend, amazement intruded.

"But," I began--and turned to the rack in which Slattin's favorite cane at that moment reposed--had reposed at the time of his death.

Yes!--there stood Slattin's cane; we had not moved it; we had disturbed nothing in that stricken house; there it stood, in company with an umbrella and a malacca.

I glanced at the cane in my hand. Surely there could not be two such in the world?

Smith collapsed on the floor at my feet.

"Examine the one in the rack, Petrie," he whispered, almost inaudibly, "but do not touch it. It may not be yet...."

I propped him up against the foot of the stairs, and as the constable began knocking violently at the street door, crossed to the rack and lifted out the replica of the cane which I held in my hand.

A faint cry from Smith--and as if it had been a leprous thing, I dropped the cane instantly.

"Merciful G.o.d!" I groaned.

Although, in every other particular, it corresponded with that which I held--which I had taken from the dacoit--which he had come to subst.i.tute for the cane now lying upon the floor--in one dreadful particular it differed.

Up to the snake's head it was an accurate copy; but the head lived!

Either from pain, fear or starvation, the thing confined in the hollow tube of this awful duplicate was become torpid. Otherwise, no power on earth could have saved me from the fate of Abel Slattin; for the creature was an Australian death-adder.

CHAPTER XI. THE WHITE PEAc.o.c.k

Nayland Smith wasted no time in pursuing the plan of campaign which he had mentioned to Inspector Weymouth. Less than forty-eight hours after quitting the house of the murdered Slattin, I found myself bound along Whitechapel Road upon strange enough business.

A very fine rain was falling, which rendered it difficult to see clearly from the windows; but the weather apparently had little effect upon the commercial activities of the district. The cab was threading a hazardous way through the cosmopolitan throng crowding the street. On either side of me extended a row of stalls, seemingly established in opposition to the more legitimate shops upon the inner side of the pavement.

Jewish hawkers, many of them in their shirt-sleeves, acclaimed the rarity of the bargains which they had to offer; and, allowing for the difference of costume, these tireless Israelites, heedless of climatic conditions, sweating at their mongery, might well have stood, not in a squalid London thoroughfare, but in an equally squalid market-street of the Orient.

They offered linen and fine raiment; from footgear to hair-oil their wares ranged. They enlivened their auctioneering with conjuring tricks and witty stories, selling watches by the aid of legerdemain, and fancy vests by grace of a seasonable anecdote.

Poles, Russians, Serbs, Roumanians, Jews of Hungary, and Italians of Whitechapel mingled in the throng. Near East and Far East rubbed shoulders. Pidgin English contested with Yiddish for the ownership of some tawdry article offered by an auctioneer whose nationality defied conjecture, save that always some branch of his ancestry had drawn nourishment from the soil of Eternal Judea.

Some wearing mens' caps, some with shawls thrown over their oily locks, and some, more true to primitive instincts, defying, bare-headed, the unkindly elements, bedraggled women--more often than not burdened with m.u.f.fled infants--crowded the pavements and the roadway, thronged about the stalls like white ants about some choicer carrion.

And the fine drizzling rain fell upon all alike, pattering upon the hood of the taxi-cab, trickling down the front windows; glistening upon the unctuous hair of those in the street who were hatless; dewing the bare arms of the auctioneers, and dripping, melancholy, from the tarpaulin coverings of the stalls. Heedless of the rain above and of the mud beneath, North, South, East, and West mingled their cries, their bids, their blandishments, their raillery, mingled their persons in that joyless throng.

Sometimes a yellow face showed close to one of the streaming windows; sometimes a black-eyed, pallid face, but never a face wholly sane and healthy. This was an underworld where squalor and vice went hand in hand through the beautiless streets, a melting-pot of the world's outcasts; this was the shadowland, which last night had swallowed up Nayland Smith.

Ceaselessly I peered to right and left, searching amid that rain-soaked company for any face known to me. Whom I expected to find there, I know not, but I should have counted it no matter for surprise had I detected amid that ungracious ugliness the beautiful face of Karamaneh the Eastern slave-girl, the leering yellow face of a Burmese dacoit, the gaunt, bronzed features of Nayland Smith; a hundred times I almost believed that I had seen the ruddy countenance of Inspector Weymouth, and once (at which instant my heart seemed to stand still) I suffered from the singular delusion that the oblique green eyes of Dr. Fu-Manchu peered out from the shadows between two stalls.

It was mere phantasy, of course, the sick imaginings of a mind overwrought. I had not slept and had scarcely tasted food for more than thirty hours; for, following up a faint clue supplied by Burke, Slattin's man, and, like his master, an ex-officer of New York Police, my friend, Nayland Smith, on the previous evening had set out in quest of some obscene den where the man called Shen-Yan--former keeper of an opium-shop--was now said to be in hiding.

Shen-Yan we knew to be a creature of the Chinese doctor, and only a most urgent call had prevented me from joining Smith upon this promising, though hazardous expedition.

At any rate, Fate willing it so, he had gone without me; and now--although Inspector Weymouth, a.s.sisted by a number of C. I. D. men, was sweeping the district about me--to the time of my departure nothing whatever had been heard of Smith. The ordeal of waiting finally had proved too great to be borne. With no definite idea of what I proposed to do, I had thrown myself into the search, filled with such dreadful apprehensions as I hope never again to experience.

I did not know the exact situation of the place to which Smith was gone, for owing to the urgent case which I have mentioned, I had been absent at the time of his departure; nor could Scotland Yard enlighten me upon this point. Weymouth was in charge of the case--under Smith's direction--and since the inspector had left the Yard, early that morning, he had disappeared as completely as Smith, no report having been received from him.

As my driver turned into the black mouth of a narrow, ill-lighted street, and the glare and clamor of the greater thoroughfare died behind me, I sank into the corner of the cab burdened with such a sense of desolation as mercifully comes but rarely.

We were heading now for that strange settlement off the West India Dock Road, which, bounded by Limehouse Causeway and Pennyfields, and narrowly confined within four streets, composes an unique Chinatown, a miniature of that at Liverpool, and of the greater one in San Francisco. Inspired with an idea which promised hopefully, I raised the speaking tube.

"Take me first to the River Police Station," I directed; "along Ratcliffe Highway."

The man turned and nodded comprehendingly, as I could see through the wet pane.

Presently we swerved to the right and into an even narrower street. This inclined in an easterly direction, and proved to communicate with a wide thoroughfare along which pa.s.sed brilliantly lighted electric trams. I had lost all sense of direction, and when, swinging to the left and to the right again, I looked through the window and perceived that we were before the door of the Police Station, I was dully surprised.

In quite mechanical fashion I entered the depot. Inspector Ryman, our a.s.sociate in one of the darkest episodes of the campaign with the Yellow Doctor two years before, received me in his office.

By a negative shake of the head, he answered my unspoken question.

"The ten o'clock boat is lying off the Stone Stairs, Doctor," he said, "and co-operating with some of the Scotland Yard men who are dragging that district--"

I shuddered at the word "dragging"; Ryman had not used it literally, but nevertheless it had conjured up a dread possibility--a possibility in accordance with the methods of Dr. Fu-Manchu. All within s.p.a.ce of an instant I saw the tide of Limehouse Reach, the Thames lapping about the green-coated timbers of a dock pier; and rising--falling--sometimes disclosing to the pallid light a rigid hand, sometimes a horribly bloated face--I saw the body of Nayland Smith at the mercy of those oily waters. Ryman continued:

"There is a launch out, too, patrolling the riverside from here to Tilbury. Another lies at the breakwater"--he jerked his thumb over his shoulder. "Should you care to take a run down and see for yourself?"

"No, thanks," I replied, shaking my head. "You are doing all that can be done. Can you give me the address of the place to which Mr. Smith went last night?"

"Certainly," said Ryman; "I thought you knew it. You remember Shen-Yan's place--by Limehouse Basin? Well, further east--east of the Causeway, between Gill Street and Three Colt Street--is a block of wooden buildings. You recall them?"

"Yes," I replied. "Is the man established there again, then?"

"It appears so, but, although you have evidently not been informed of the fact, Weymouth raided the establishment in the early hours of this morning!"

"Well?" I cried.

"Unfortunately with no result," continued the inspector. "The notorious Shen-Yan was missing, and although there is no real doubt that the place is used as a gaming-house, not a particle of evidence to that effect could be obtained. Also--there was no sign of Mr. Nayland Smith, and no sign of the American, Burke, who had led him to the place."

"Is it certain that they went there?"

"Two C. I. D. men who were shadowing, actually saw the pair of them enter. A signal had been arranged, but it was never given; and at about half past four, the place was raided."

"Surely some arrests were made?"

"But there was no evidence!" cried Ryman. "Every inch of the rat-burrow was searched. The Chinese gentleman who posed as the proprietor of what he claimed to be a respectable lodging-house offered every facility to the police. What could we do?"

"I take it that the place is being watched?"

"Certainly," said Ryman. "Both from the river and from the sh.o.r.e. Oh!

they are not there! G.o.d knows where they are, but they are not there!"
