In the afternoon he again isolated himself, and on the succeeding days I saw no more of him. Did he avoid me because he thought he had told me too much, too much and not enough? At first I believed this to be the case, and without making any explanations, I informed Mairieux that I was about to leave. Of what use was it to remain?

“No,” he urged, “do not affront him that way.”

“He would not notice my absence,” I said.

“Listen,” replied M. Mairieux. “For one or two weeks last year he was so depressed that he moved me to pity. Besides, your company will be welcome to us. Wait, I beg of you.”

“But what does he do all day?” I asked.

We were talking in the carriage road. Raymond Cernay’s apartments consisted of three adjoining rooms on the second story, a library, a study, and a bedroom. The autumn days were so mild that the large bay window of the study was open and we could see him seated at a table, with his head between his hands. He was reading or studying. A ray of light came to me—he disappeared in order to work the better on his monoplanes.

“Calculations?” I asked M. Mairieux.

“I don’t think so.”

In spite of myself, the secret of this man’s life tormented, I was about to say haunted, me. Why at our first meeting had he imagined himself to be the Lord of Burleigh whose wife could not live outside of her own environment? What was there connected with Mme. Cernay for which he blamed himself? Why did he insist upon punishment for some unknown crime or crimes which nobody but he suspected?
