"But how to obtain that strong, vigorous health, Miss Castlemaine, is not that the great question?"

"By breathing pure air. By partaking of pure food, mental and moral, as well as physical," she replied. "The conversation so far has made me feel quite morbid."

John Castlemaine and Mr. Lowry laughed heartily, while Purvis heaved a sigh of relief. He had wondered how this conversation affected Olive, and he rejoiced that it had not pleased her. As for Leicester, he gave her a quick glance of admiration. He was glad that Winfield had mentioned her. Here at least was a woman better worth winning than any he had ever seen. Again he felt ashamed of the conversation that had taken place at the club, even while he was more than ever determined to prove to Purvis and Sprague that he was right in his contention.

"At any rate, Purvis cannot accuse me of hiding my opinions," he said to himself, and then he turned the course of the conversation.

During the rest of the evening Leicester seemed to forget his sad, hopeless opinions, and he completely restored the good opinion which John Castlemaine had formed concerning him at first, and which he had well-nigh lost during the time when Leicester was giving expression to his cynical views. And this was no wonder, for even Purvis himself was well-nigh carried away by his cleverness. He spoke well concerning current books and current events. He compared notes with Olive concerning places both had visited and books which both had read. He exerted himself to be agreeable, and he succeeded vastly. Perhaps the atmosphere of the house helped him, perhaps he found in Olive one who helped to restore his good opinion of womanhood; perhaps he realised his determination to win his wager and obtain the promise of Olive Castlemaine to be his wife. Be that as it may, the Radford Leicester of the early part of the evening was not the Radford Leicester of the latter.

Olive felt this. He reminded her of Dr. Jekyll and Mr. Hyde. His dual personality became somewhat of a problem. Which was the real man? Both were interesting—almost fascinating. He was clever when the pessimistic mood was upon him; he was far more clever when he became the student and the scholar, talking brilliantly of books, of architecture, of art, and of the struggling, troubled life of humanity.

Concerning religion he said nothing. Once or twice, when Olive introduced the subject into their conversation, he avoided it. Perhaps he shrank from expressing his lack of faith in those truths by which, to Olive, all the opinions of men must be tested; but of other things he spoke freely and well. Moreover, the girl helped him. Her straightforwardness, her freedom from petty meannesses, and her wide, intelligent outlook on life made him for the moment forget his oft-expressed opinion of women. Besides, he had his part to play, and he played it.

Presently a servant came saying that Mr. Lowry's motor-car was at the door.

"You are not going up to town by train?" said Mr. Castlemaine.

"No, I had the car in London, and I thought I might as well use it," replied Mr. Lowry; "besides, I can get back quicker in the car."
