Poirot nodded. “What was taken from the safe? Have you any idea?”

“We’ve been going into that with the junior partner of the firm and Mrs. Davenheim. Apparently there was a considerable amount in bearer bonds, and a very large sum in notes, owing to some large transaction having been just carried through. There was also a small fortune in jewellery. All Mrs. Davenheim’s jewels were kept in the safe. The purchasing of them had become a passion with her husband of late years, and hardly a month passed that he did not make her a present of some rare and costly gem.”

“Altogether a good haul,” said Poirot thoughtfully. “Now, what about Lowen? Is it known what his business was with Davenheim that evening?”
