I was now convinced we had come on a fool's errand that was like to end evilly for us, but, being a fool, I held my peace and said nothing to Ajax, who confessed later that if I had spoken he would have seconded a motion to retreat. We advanced, sensible that we were being trapped: a psychological fact not without interest.

Opposite the door through which we had just passed was another door as stout as the first. The Chinaman unlocked this with a small key, and allowed us to enter, the guide with the candle leading the way. And then, in a jiffy, before we had time to glance round us, the candle was extinguished; the door was closed; we heard the click of a patent lock; and we knew that we were alone and in darkness.

The first thing that Ajax said, and his voice was not pleasant to hear, was: "This serves us right. Of all the confounded fools who meddle with what does not concern them, we are the greatest."

Then I heard him fumbling for his matchbox, and then, when he discovered that it was empty, he made some more remarks not flattering to himself or me. I was more frightened than angry; with him rage and disgust were paramount.

We stood there in that squalid darkness for about a hundred years (it was really ten minutes), and then the voice of our guide seemed to float to us, as if from an immeasurable distance.

"Boys," he said. "How air ye makin' it?"

Ajax answered him quite coolly--

"What do you want? Our money of course. What else?"

The fellow did not reply at once. These opium fiends have no bowels of compassion. He was doubtless chuckling to himself at his own guile. When he did speak, the malice behind his words lent them point.

"Your money? The five you gave me'll keep me a week, and after that I'll come for more."
