"He has been here," said Ah Wu, "for many months."

"Strange," said Cheong-Chau, "that I have never seen him before!"

Frank was, at first, at a loss to explain what motive Ah Wu could have for telling such a deliberate falsehood. It then occurred to him that Ah Wu could not explain truthfully who he was without mentioning Ling; and it was--from Ah Wu's point of view--of extreme importance to keep the name of Ling out of the whole affair. If Cheong-Chau but knew that the great Honanese was in the building, he would not have remained in the place for five seconds, much less would he have been so careless as to allow his physical and mental capacities to be temporarily subdued by the subtle fumes of the opium poppy.

"Come here, boy," said Cheong-Chau, who had not yet removed his eyes from Frank. "I want to look at you more closely."

The boy went forward in fear and trembling. Cheong-Chau grasped him by a wrist, and drew him downward, so that their faces were not more than a foot apart.

"You bear," said Cheong-Chau, speaking very deliberately, "a most remarkable resemblance to the very man I am looking for. What is your name?"

"Ah Li," said Frank.

The boy's heart was beating like a sledgehammer. He felt instinctively that the Sword of Damocles, which had been suspended for so long above his head, was at last about to fall. That the result would be fatal to himself, and those whose lives depended upon him, he could not for a moment doubt.

"I come from Sanshui," said he, in a weak voice that quailed.

Cheong-Chau suddenly rose to his feet and lifted his voice to a kind of shriek. It was the voice Frank had heard when Cheong-Chau addressed his followers in the gloomy nave of the temple; it was the same voice the man had used on the occasion when he staggered into the cave, senseless and drugged with opium.
