The Revolt of the Angels by Anatole France

Although he had enjoyed Madame des Aubels' favours for six whole months, Maurice still loved her. True they had had to separate during the summer. For lack of funds of his own he had had to go to Switzerland with his mother, and then to stop with the whole family at the Chateau d'Esparvieu. She had spent the summer with her mother at Niort, and the autumn with her husband at a little Normandy seaside place, so that they had hardly seen each other four or five times. But since the winter, kindly to lovers, had brought them back to town again, Maurice had been receiving her twice a week in his little flat in the Rue de Rome, and received no one else. No other woman had inspired him with feelings of such constancy and fidelity. What augmented his pleasure was that he believed himself loved, and indeed he was not unpleasing.

He thought that she did not deceive him, not that he had any reason to think so, but it appeared right and fitting that she should be content with him alone. What annoyed him was that she always kept him waiting, and was unpunctual in coming to their meeting-place; she was invariably late, -- at times very late.
