Mrs. Berlyn bowed.
“Thank you for that. Of course I recognise that you must investigate all possibilities, and I recognise, too, that you will not give any weight to what I am going to say. But I must tell you that if you suspect Mr. Berlyn you are making a mistake. Though he was not perfect, he was utterly incapable of a crime like that—utterly. If you had ever met him you would have known that. I wish I could say or do something to convince you. Besides, if he were alive, why did he disappear? If he were guilty, would he not have come forward with a story that Mr. Pyke had gone alone across the moor and been lost in the mires?”
French had already noted the point as the chief difficulty in his theory, and he admitted it fully. He added that Mrs. Berlyn’s statement had made an impression on him and that he would not fail to bear it in mind. Then promising to let her know the result of his enquiry, he took his leave.
He had not lied when he said her statement had impressed him. That it represented her firm conviction he had not the least doubt. And it certainly was a point in Berlyn’s favour that such testimony should be forthcoming from his wife, when it was evident that their married life had been an indifferent success. Of course it might be simply that the woman did not wish to be involved in the misery and disgrace which would come with proof of Berlyn’s guilt. But French did not think it was this. Her thought had seemed to be for her husband rather than herself.
It was still fairly early in the afternoon and French thought he would have time to make another call. He therefore walked up the Fulham Road and took an eastbound district train at South Kensington. Half an hour later he was at the headquarters of the Ardlo Magneto Company in Queen Elizabeth Street.
When the managing director heard French’s business he touched a bell.
“You had better see Mr. Illingworth, our chief electrical engineer,” he said. “I am afraid I could not help you in these technical matters.”
Mr. Illingworth was a pleasant young man with a quiet, efficient manner. He took French to his office, supplied him with cigarettes, and asked what he could do for him.
French put his problem, recounting the enquiries he had already made.
“Those people told you quite correctly,” was Mr. Illingworth’s answer. “Your question is this: Could a man drive a car up to a certain place and then short circuit the magneto armature so that the car couldn’t be started again? The answer is, Yes, but not without leaving marks.”
