"I do not know," said Kahn Meng finally. "It is hideous. I have seen them. That will be stopped!" he added tensely.

Under the lantern they paused, and Peter found his strange companion to be examining his features intently.

"I can add nothing to what has been said," Kahn Meng went on. "I have much to attend to now. We are starting immediately. At present will you trust me as I trust you?" He extended his right hand, and Peter clasped it silently.

The ripe old moon of Tibet was creeping from its bed, tipping the pointed tents with a soft glow.

On such another night as this Peter had first dared to enter the City of Stolen Lives, and the faint, mysterious sounds of a caravan at rest stirred up old memories.

The probable treatment of Eileen at the hands of Len Yang's king was too terrible for him to contemplate. And he was as helpless at this instant as though he were on the other side of the Pacific Ocean.

A hot flood of anger welled up in his breast. His palms began to sweat. Each minute was drawing her closer to the moldy walls.

He could picture her struggling in the arms of the giant Mongolian. He could see the great drawbridge swinging down to the white road in the moonlight or the blistering heat of noonday. And on the hill, like a greedy, white vulture, he could see that solemn palace with minarets stretching like claws to the sky, crouching upon the red slime vomited forth by the mines.

A cool voice startled him. Kahn Meng came out of the darkness.

"Two hundred men will accompany us. The others will remain here in case an attack is made on our rear. There may be trouble. Of course, I could go, unharmed, into Len Yang by the mountain road; but as soon as I entered I would be helpless—a prisoner forever. He knows I am returning. He is expecting me. But he does not know that half his garrison are loyal to me. The yellow-whiskered one will not be glad to see me," he added with a malicious grin.
