“One more question, M. Kettering,” he said. “Will you give me the date when you last saw your wife?”

“Let me see,” Kettering reflected. “It must have been⁠—yes, over three weeks ago. I am afraid I can’t give you the date exactly.”

“No matter,” said Poirot drily; “that is all I wanted to know.”

“Well,” said Derek Kettering impatiently, “anything further?”

He looked towards M. Carrège. The latter sought inspiration from Poirot, and received it in a very faint shake of the head.

“No, M. Kettering,” he said politely; “no, I do not think we need trouble you any further. I wish you good morning.”
