Mr. Carter looked inquiringly at him, and Tommy explained. The other nodded thoughtfully.

“True, that’s rather a curious point. Unless the mention of the Ritz was an accidental remark?”

“It might have been, sir. But they must have found out about me suddenly in some way.”

“Well,” said Mr. Carter, looking round him, “there’s nothing more to be done here. What about some lunch with me?”

“Thanks awfully, sir. But I think I’d better get back and rout out Tuppence.”

“Of course. Give her my kind regards and tell her not to believe you’re killed too readily next time.”

Tommy grinned.
