The Combined Maze by May Sinclair

Ransome had barely risen from that sleep of exhaustion when he realized the disastrous character of the night's adventure. He was no longer uplifted by any sense of sanction and of satisfaction. Of the pride of life there remained in him only sufficient to prevent him from regarding his behavior as in any sense a shame and a disaster to his own youth. Otherwise his mood was entirely penitential. He could not look at the thing as it affected himself. However it might be for him, he had wronged Violet, and that was calamity enough for any man to face. According to all his instincts and traditions, he had wronged her.

Of course, he was going to marry her. He was going to marry her at once; as soon as ever they could get their banns put up. It never occurred to him that delay could, in such a case, be possible.
