This last cellar was evidently for the cheapest class of customers. There were berths here too, but the curtains were poor, or non-existent, and many Chinamen lay about the floor on strips of matting. The atmosphere was foetid, and thick with opium smoke. As we moved towards a rough partition at the further end, our figures tore the grey cloud as if it had been made of gauze.

"Your friend lies very sick in a room there," said my guide, speaking for the first time since he had stepped through the panel. "We have paid for his keep a long time now."

I made no answer, only following with my eyes the gesture he made, pointing at the unpainted wooden partition. In this partition were three doors, also of rough, unpainted wood. Two stood ajar, showing small rooms which I fancied were used by the attendants and opium "cooks." One door was closed. My companion opened it, indicating, with a smile, that it possessed no lock, only an old-fashioned latch. "You need not fear to go in and talk with your friend alone," he said, in his low, monotonous voice. "You see, he is not a prisoner! And we cannot make you one."

I shrugged my shoulders, and passed him without a word, shutting the door behind me as I entered the wretched den on the other side. It was lit by one paraffin lamp, supported by a bracket attached to the wall, and such light as existed brought out from the shadows the vague lumpish shape of a mattress on the floor. Two or three odds and ends of furniture lurked in corners, but I scarcely saw their squalor. My one thought was for a dark form stretched on the grey heap of bedding.

I bent over it, and a hand seemed to grip my heart. "My God, poor old Don! What have they done to you?" I broke out.

A skeleton in rags lay on the filthy mattress. The yellow light from the bracket lamp lit his great eyes as they suddenly opened, in deep hollows. Even his face looked fleshless. There were streaks of grey in the dark hair at his temples, and an unkempt beard mingled with the shadows under his cheekbones. This was what remained of Donald Allendale, one of the smartest and handsomest men in the army.

He stared at me dully for an instant, his eyes like windows of glass With no intelligence behind them. Then abruptly they seemed to come alive. "Jack!" he gasped. "Am I—dreaming you?"

"No, dear old chap, no," I assured him, down on one knee by the mattress, slipping an arm under his head. "It's Jack right enough, come to take you out of this and make you the man you were again."

As I spoke, slowly and distinctly, so that the comforting words might reach his sick soul, I heard a faint, stealthy noise outside. There was a slight squeak as of iron scraping against wood, and in a flash I guessed what had happened. My guide had made a point of showing that the door could not be locked; and I, like a fool—in my haste to see Don—hadn't sought other means of fastening it, more efficient than any lock. I guessed that a bar of wood or iron had now been placed across the door, the two ends in rungs or brackets which I had passed unnoticed.

"Well!" I said to myself, "the mischief's done. No use kicking against the pricks till I'm ready to kick. And I shan't be ready till I've seen what can be done for Allendale."
