“No,” said French. “Not until you explain why you denied having been out when Sergeant Daw asked you.”

“That, as I have said, was a mistake. But you can surely understand my motive. When I heard the sergeant’s story I recognised at once that my having taken out the car was a very unfortunate thing for me. I felt sure that foul play would sooner or later be suggested and I thought I should be suspected. I couldn’t prove where I had been and I was afraid I should not be believed when I explained.”

“I’m afraid that is not very clear. Why did you imagine that foul play would be suspected?”

Domlio hesitated.

“I suppose,” he said at last, “things have gone so far there is no use in trying to keep anything back. I knew that there was bad blood between Berlyn and Pyke. The sergeant’s news at once suggested to me that the trouble might have come to a head. I hoped not, of course, but the idea occurred to me.”

“Even yet I don’t understand. What was the cause of the bad blood between those two and how did you come to know of it?”

“Surely,” Domlio protested, “it is not necessary to go into that? I am only accounting for my own actions.”

“It is necessary in order to account for your own actions.”

Domlio squared his shoulders.

“I don’t think I should tell you, only that, unfortunately, it is pretty well common property. I hate dragging in a lady’s name, though you have already done it, but the truth is that they had had a misunderstanding about Mrs. Berlyn.”
