"And now," he roared, "lie to me again."

In the meantime, in spite of such extraordinary happenings, Frank had taken in his surroundings. Ah Wu's opium den has been already described--except that we saw it before at night, when the place was crowded. On this occasion there was only one man asleep upon a couch in the lower room. It was about twelve o'clock in the morning, and at this hour, as a general rule, Chinese opium dens are empty, the smokers of the previous evening having departed and the day's customers not having arrived.

Strangely enough, the vase had not broken, but in falling to the floor it had made a considerable noise, and this was sufficient to awaken the sleeper, who evidently suffered from a guilty conscience. The man sprang to his feet, and rushed to the entrance, as if he intended to escape. There, of course, he found his way barred by Ling, who lifted one of his huge fists as if to strike the fellow. The man jumped backward like a cat that finds itself face to face with a dog. And it was then, once again, that Ling burst into one of his boisterous fits of laughter.

"And here's the flunkey!" he cried. "Here's the Hong-Kong cur-dog! Have you also a mind to lie to me, or do you set a value on your life? I tell you truly, I am not here to exchange words. I know what I want, and I am come to get it. Hands up!" he shouted, seeing the man move one of his hands to his waistbelt, under his coat, where he might have carried a firearm. "Hands up, or I wring your neck like a duck!"

In fear and trembling the man lifted both hands above his head. Frank regarded him then for the first time. And it was as if the boy's heart had suddenly ceased to beat when he recognised Yung How, his uncle's servant.

[CHAPTER XIV--HOW LING SNUFFED THE CANDLE]

Frank had every reason to suppose that he would be recognised in spite of his disguise. To deceive Men-Ching was one thing, but Yung How had known the boy for years. More than ever he desired to escape. It was clear that both Yung How and even Ah Wu himself were equally anxious to get away from the room. All three of them, however, were caught like rats in a trap, for Ling guarded the entrance, and it was as much as the life of any one of them was worth to attempt to pass, either by force or stealth.

Ling approached Yung How, lifted the man's coat and drew a large nickel-plated revolver from his belt.

"I thought so," said he. "I draw the jackal's teeth."

So saying, he thrust the revolver into his pocket.
