Even when the peculiar duties of my friend, Paul Harley, called him away from England, the lure of this miniature Orient which I had first explored under his guidance, often called me from my chambers. In the house with the two doors in Wade Street, Limehouse, I would discard the armour of respectability, and, dressed in a manner unlikely to provoke comment in dockland, would haunt those dreary ways sometimes from midnight until close upon dawn. Yet, well as I knew the district and the strange and often dangerous creatures lurking in its many burrows, I experienced a chill partly physical and partly of apprehension to-night; indeed, strange though it may sound, I hastened my footsteps in order the sooner to reach the low den for which I was bound—Malay Jack's—a spot marked plainly on the crimes-map and which few respectable travellers would have regarded as a haven of refuge.

But the chill of the adjacent river, and some quality of utter desolation which seemed to emanate from the deserted wharves and ramshackle buildings about me, were driving me thither now; for I knew that human companionship, of a sort, and a glass of good liquor—from a store which the Customs would have been happy to locate—awaited me there. I might chance, too, upon Durham or Wessex, of New Scotland Yard, both good friends of mine, or even upon the Terror of Chinatown, Chief Inspector Kerry, a man for whom I had an esteem which none of his ungracious manners could diminish.

I was just about to turn to the right into a narrow and nameless alley, lying at right angles to the Thames, when I pulled up sharply, clenching my fists and listening.

A confused and continuous sound, not unlike that which might be occasioned by several large and savage hounds at close grips, was proceeding out of the darkness ahead of me; a worrying, growling, and scuffling which presently I identified as human, although in fact it was animal enough. A moment I hesitated, then, distinguishing among the sounds of conflict an unmistakable, though subdued, cry for help, I leaped forward and found myself in the midst of the melee. This was taking place in the lee of a high, dilapidated brick wall. A lamp in a sort of iron bracket spluttered dimly above on the right, but the scene of the conflict lay in densest shadow, so that the figures were indistinguishable.

“Help! By Gawd! they're strangling me———”

From almost at my feet the cry arose and was drowned in Chinese chattering. But guided by it I now managed to make out that the struggle in progress waged between a burly English sailorman and two lithe Chinese. The yellow men seemed to have gained the advantage and my course was clear.

A straight right on the jaw of the Chinaman who was engaged in endeavouring to throttle the victim laid him prone in the dirty roadway. His companion, who was holding the wrist of the recumbent man, sprang upright as though propelled by a spring. I struck out at him savagely. He uttered a shrill scream not unlike that of a stricken hare, and fled so rapidly that he seemed to melt in the mist.

“Gawd bless you, mate!” came chokingly from the ground—and the rescued man, extricating himself from beneath the body of his stunned assailant, rose unsteadily to his feet and lurched toward me.

As I had surmised, he was a sailor, wearing a rough, blue-serge jacket and having his greasy trousers thrust into heavy seaboots—by which I judged that he was but newly come ashore. He stooped and picked up his cap. It was covered in mud, as were the rest of his garments, but he brushed it with his sleeve as though it had been but slightly soiled and clapped it on his head.

He grasped my hand in a grip of iron, peering into my face, and his breath was eloquent.
