She shrank perceptibly. "If—if you won't make it too hard for me."

"I can't answer for that," he returned. "It depends entirely upon yourself. My knowledge does not amount to anything very staggering in itself. It is only this—that I know a certain person who would cheerfully sacrifice all he has to make you happy, and that you have no more cause to fear persecution from that person than from the man in the moon."

He paused; but Muriel did not speak. She was still absently turning her engagement ring round and round.

"To verify this," he said, "I will tell you something which I am sure you don't know—which in fact puzzled me, too, considerably, for some time. He has already sacrificed more than most men would care to venture in a doubtful cause. It was no part of his plan to follow you to England. He set his face against it so strongly that he very nearly ended his mortal career for good and all in so doing. As it was, he suffered for his lunacy pretty heavily. You know what happened. He was forced to come in the end, and he paid the forfeit for his delay."

Again he paused, for Muriel had sprung upright with such tragedy in her eyes that he knew he had said enough. The next moment she was on her feet, quivering all over as one grievously wounded.

"Oh, do you know what you are saying?" she said, and in her voice there throbbed the cry of a woman's wrung heart. "Surely—surely he never did that—for me!"

He did not seem to notice her agitation. "It was a fairly big price to pay for a piece of foolish sentiment, eh?" he said. "Let us hope he will know better next time."

He looked up at her with a faintly cynical smile, but she was standing with her face averted. He saw only that her chin was quivering like a hurt child's.

"Come," he said at length. "I didn't tell you this to distress you, you know. Only to set your mind at rest, so that you might sleep easy."

She mastered herself with an effort, and turned towards him. "I know; yes, I know. You—you have been very kind. Good-night, doctor."
