"I will not forget," he said importantly. "You will see Mirai Khan again. I swear it. And I will tell you something. Wu Fang Chien is in Liangchowfu."

With that the man shambled off down an alley, looking for all the world like a shaggy dog with unusually long legs. Gray stared after him with a smile. Then he turned back toward the inn.

That night there was a feast in Liangchowfu. The sound of the temple drums reached to the inn. Lanterns appeared on the house fronts across the street. Throngs of priests passed by in ceremonial procession, bearing lights. In the inn courtyard a group of musicians took their stand, producing a hideous mockery of a tune on cymbals and one-stringed fiddles. But the main room of the inn, where the eating tables were set with bowls and chop-sticks, was deserted except for a wandering rooster.

"I'm going out to see the show," asserted Gray, who was weary of inaction.

"What!" The Syrian stared at him, fingering his beard restlessly. "With Wu Fang Chien in the town!"

"Certainly. There's nothing to be done here. I may be able to pick up information which will be useful—if we are in danger."

Delabar tossed his cigarette away and shrugged his shoulders.

"We are marked men, my young friend. I saw this afternoon that a guard has been posted at the town gates. Those musicians yonder are spies. The master of the inn is in the stable, with our men."

"Then we'll shake our escort for a while." Gray's smile faded. "Look here, Professor. I'm alive to the pickle we're in. We've got to get out of this place. And I want to have a look at that hole in the wall Mirai Khan told me about. For one thing—to see if horses can get through it."

Delabar accompanied him out of the courtyard, into the street. Gray noted grimly that the musicians ceased playing with their departure. He beckoned Delabar to follow and turned down the alley he had visited that afternoon. Looking over his shoulder he saw a dark form slip into the entrance of the alley.
