“I don’t think so. I took to him at once. No, I’m pretty sure Dr. Hall’s all right.”

“Hall, did you say?” asked Sir James. “That is curious⁠—really very curious.”

“Why?” demanded Tuppence.

“Because I happened to meet him this morning. I’ve known him slightly on and off for some years, and this morning I ran across him in the street. Staying at the Métropole, he told me.” He turned to Julius. “Didn’t he tell you he was coming up to town?”

Julius shook his head.

“Curious,” mused Sir James. “You did not mention his name this afternoon, or I would have suggested your going to him for further information with my card as introduction.”
