No objection was offered to our request to examine Mr. Morowitch's personal effects in the library, and accordingly Craig ransacked the desk and the letter-file. There was practically nothing to be discovered.
“Had Mr. Morowitch ever received any threats of robbery?” asked Craig, as he stood before the desk.
“Not that I know of,” replied Mrs. Morowitch. “Of course every jeweller who carries a large stock of diamonds must be careful. But I don't think my husband had any special reason to fear robbery. At least he never said anything about it. Why do you ask?”
“Oh, nothing. I merely thought there might be some hint as to the motives of the robbery,” said Craig. He was fingering one of those desk-calendars which have separate leaves for each day with blank spaces for appointments.
“'Close deal Poissan,'” he read slowly from one of the entries, as if to himself. “That's strange. It was the correspondence under the letter 'P' that was destroyed at the office, and there is nothing in the letter-file here, either. Who was Poissan?”
Mrs. Morowitch hesitated, either from ignorance or from a desire to evade the question. “A chemist, I think,” she said doubtfully. “My husband had some dealings with him—some discovery he was going to buy. I don't know anything about it. I thought the deal was off.”
“The deal?”
“Really, Mr. Kennedy, you had better ask Mr. Kahan. My husband talked very, little to me about business affairs.”
“But what was the discovery?”
“I don't know. I only heard Mr. Morowitch and Mr. Kahan refer to some deal about a discovery regarding diamonds.”
