They mounted the stairs to the hotel’s second floor, and walked along the deck until they reached Dr. Weber’s room.

Hale had done his job. The door was open. Biff entered the room. Likake, his heart pounding, was right on his heels.

The room was faintly lighted by the moonlight from outside. Biff paused in the middle of the room to allow his eyes to become accustomed to the dim light.

Then he started his search. Ever since the call to Indianapolis, Biff had wondered about the letter mentioned during the conversation. His father had said, “Forget it,” but Biff hadn’t been able to. The letter had to mean something. Where would a man like Dr. Weber hide a letter? Biff asked himself. He felt certain that Dr. Weber had been kidnaped, but he didn’t think the abductors had the letter. If they did, then why were they holding the doctor?

“Course, I could be all wrong,” Biff told himself. But he didn’t think he was.

“Likake. Li. Come here,” Biff whispered and was startled to hear Li’s voice right back of him.

“I am here. Right with you.” Li sounded scared, Biff thought.

“Now where do we look?” Li asked.
