“What you tell me about the girl puzzled me,” said Mr. Carter. “You believe that she deliberately went back?”

“It would seem so, sir. She ran upstairs while I was getting the door open.”

“H’m, she must belong to the gang, then; but, being a woman, didn’t feel like standing by to see a personable young man killed. But evidently she’s in with them, or she wouldn’t have gone back.”

“I can’t believe she’s really one of them, sir. She—seemed so different——”

“Good-looking, I suppose?” said Mr. Carter with a smile that made Tommy flush to the roots of his hair. He admitted Annette’s beauty rather shamefacedly.

“By the way,” observed Mr. Carter, “have you shown yourself to Miss Tuppence yet? She’s been bombarding me with letters about you.”

“Tuppence? I was afraid she might get a bit rattled. Did she go to the police?”

Mr. Carter shook his head.

“Then I wonder how they twigged me.”

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