“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?”

“Well, the two men were apparently not on very good terms. Lowen is a speculator in quite a small way. Nevertheless, he has been able once or twice to score a coup off Davenheim in the market, though it seems they seldom or never actually met. It was a matter concerning some South American shares which led the banker to make his appointment.”

“Had Davenheim interests in South America, then?”

“I believe so. Mrs. Davenheim happened to mention that he spent all last autumn in Buenos Ayres.”

“Any trouble in his home life? Were the husband and wife on good terms?”

“I should say his domestic life was quite peaceful and uneventful. Mrs. Davenheim is a pleasant, rather unintelligent woman. Quite a nonentity, I think.”

“Then we must not look for the solution of the mystery there. Had he any enemies?”

“He had plenty of financial rivals, and no doubt there are many people whom he has got the better of who bear him no particular good-will. But there was no one likely to make away with him—and, if they had, where is the body?”

“Exactly. As Hastings says, bodies have a habit of coming to light with fatal persistency.”
