With that Garluk slipped from the door. Gray heard the sound of a bar falling into place. He was shut in for the night.

CHAPTER XXIII
THE CHALLENGE

He slept little. The fate destined for Mary had come as a complete surprise. It was not strange, he reflected, that Gela should want her for a wife. Nor that Bassalor Danek should approve the marriage. He might have foreseen something of the kind.

No wonder the Gur-Khan had taken excellent care of the girl, when she was marked for the bride of his grandson. Gray swore fluently, and vainly. The calmness with which the Wusun had put him aside was irksome. He wished that he had claimed to be the husband of Mary. It was too late now.

Nor did he hope that the girl's objection, once she heard of the proposed match, would carry weight. Evidently marriage among the Wusun was arranged by the parents of the parties concerned, as in China. Bassalor Danek's word was law. And the old chieftain fully appreciated the beauty of the girl.

Gray groaned, reflecting that the coincidence of the cross that the girl wore had rendered her doubly desirable in the eyes of the Wusun. He wondered how they had seen the cross. Was the marriage to be the price of his safety? He groaned at the thought.

Flight, even if he could reach the girl, from Sungan, was not to be thought of for the present. Wu Fang Chien would be alert for just such an attempt. And Gray did not see how he could hope to win through the lepers.

"They say blood calls to blood," he muttered. Then he scowled savagely. "Confound Gela!"

He was hungry for sight of the girl. She must be worried about him, as he had not been able to visit her yesterday as he had promised. His involuntary protest had excited the suspicions of Garluk. He would find it difficult now to escape from the surveillance of the tumani, if he should make the attempt.
