The second problem he found more difficult. Rack his brains as he would, he could think of no one who might have helped Berlyn.
He thought his next plan would be an enquiry into the whereabouts at ten o’clock, on the night of the crime, of everyone whom it was possible to suspect. That, coupled with an investigation as to who was in London when the various letters were posted, should yield results.
The fact that a number of possible suspects had been at Mrs. Berlyn’s party from eight to eleven on the fatal evening seemed to rule them out. But French thought he should get some more definite information on the point. Accordingly, he went up to the works and asked for Mr. Fogden, one of those whom Lizzie Johnston had mentioned as being present.
“I heard a peculiar story about Mrs. Berlyn,” he said a propos of nothing special when they had talked for some time. “I was told she had a premonition of Mr. Berlyn’s death and was miserable and upset all that evening of the crime. A peculiar thing, if true, isn’t it?”
“Who told you that?” Mr. Fogden asked, sceptically.
“A chance remark in the bar of the Silver Tiger; I don’t know the speaker’s name nor, of course, do I know if his story was true.”
“Well, you may take it from me that it wasn’t. I was at Mrs. Berlyn’s that evening and there was nothing wrong with her that I saw.”
This gave French his lead. When he left the office he had obtained all the details of the party that he wanted. On the day before the crime Mr. Fogden had had a telephone call from Mrs. Berlyn saying that Berlyn was to be out on the following evening and that she would be alone, and asking if he and one or two of the others would come and keep her company. Eight people had turned up, including himself, Cowls and Leacock from the works, a Dr. Lancaster and his wife, and two Miss Pyms and a Miss Nesbitt from the town. All these people were very intimate and the party was quite informal. Some of them had played billiards, and the others bridge.
This information seemed to French to eliminate Fogden, Cowls, and Leacock, as well, of course, as Mrs. Berlyn herself. He spent the remainder of the day in racking his brains for other possible accomplices and in thinking out ways to learn their movements on the night in question.
Next morning he took up the matter of the whereabouts of all suspects when the incriminating letters were posted in London.
