Grant smiled involuntarily. There was an engaging childlikeness about the boy.

Then he shook himself mentally, like a dog coming out of water.

Charm. The most insidious weapon in all the human armory. And here it was, being exploited under his nose. He considered the good-natured feckless face dispassionately. He had known at least one murderer who had had that type of good looks; blue-eyed, amiable, harmless; and he had buried his dismembered fiancée in an ash pit. Tisdall's eyes were of that particular warm opaque blue which Grant had noted so often in men to whom the society of women was a necessity of existence. Mother's darlings had those eyes; so sometimes, had womanizers.

"Do you ask me to believe that in your four days together you had no suspicion at all of Miss Clay's identity?" he asked, marking time until he could bring Tisdall unsuspecting to the crucial matter.

"I suspected that she was an actress. Partly from things she said, but mostly because there were such a lot of stage and film magazines in the house. I asked her about it once, but she said: 'No names, no pack drill. It's a good motto, Robin. Don't forget. "

"I see. Did the outfit Miss Clay bought for you include an overcoat?"

"No. A mackintosh. I had a coat."

"You were wearing a coat over your evening things?"

"Yes. It had been drizzling when we set out for dinner — the crowd and I, I mean."
