1. Berlyn in all probability was consumed by jealousy, one of the strongest of human motives for crime. 2. Berlyn had an unparalleled opportunity for the deed, which only he could have arranged. 3. It was not easy to see how anyone but Berlyn could have handled the magneto affair. 4. Berlyn had the necessary position in the Veda Works to carry out the watchman and stock-card episodes. 5. Berlyn answered the description of the man who had called for the crate. 6. Berlyn had disappeared, an incomprehensible action if he were innocent. As French thought again over the accomplice, he recognised that here was the snag in his theory. Motives of personal jealousy and private wrong leave no room for an accomplice. Moreover, it was incredible that a man who had shown such ingenuity could not have devised a scheme to carry out the crime single-handed. But though French recognised that there were points in the case as yet unexplained, he saw that his own procedure was clear. He must start the search for Berlyn and he must learn the identity of the accomplice. The first of these was easy. He had compiled a pretty accurate description of the junior partner and Daw had got hold of his photograph. A note in the _Police Gazette_ would start every police officer in the country on the search. 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.”
