"You promised," she repeated. The carefully assumed composure of her voice threatened to crack; this wistfulness of his was a powerful weapon against her defense. "Oh, I'll give you the explanation," he said miserably. "I just wanted to warn you you'd not believe me." He gave her a despondent glance. "Pat, as I love you I swear that what I tell you is the truth. Do you think you can believe me?" "Yes," she murmured. The tremor had reappeared in her voice despite her efforts. Nicholas Devine turned his eyes toward the lake and began to speak. "I don't remember when I first noticed it," began Nick in a low voice, "but I'm two people. I'm me, the person who's talking to you now, and I'm--another." Pat, looking very pale and serious in the dusky light, said nothing at all.

But recently, Pat--I think it's since I fell in love with you--the struggle has been on evener terms. I've weakened or he's gained. I have to guard against him constantly; in any moment of weakness he may slip in, as on our ride last week, when
