He accepted her hand promptly and evinced no disposition to relinquish it. “You are so cold, though,” he said ruefully. “Your forgiveness is merely indifference. But of course,” hastily, “you are absorbed in much weightier matters than friendship. I can imagine how insignificant all other episodes of your past must seem—”

“Oh, if it were not for you I might have been here before to-day, and in a much worse predicament. I doubt if I should have left him as soon as I did if it had not been for your unpleasant truths. I was drifting, and also drifting toward morbidity, where I might have been capable of anything. If I had really killed him and been arrested I should have said so, and even you could not have saved me.”

“Oh, it would have been easier: I could have got you off on the plea of insanity. But am I really a link in the chain? I am egoistical—and interested—enough to be—pleased.”

“Oh, yes,” she said, laughing a little. “You have had a good deal more to do with forging some of the links than you imagine.”

His hand was beginning to tremble, and she withdrew her own. He did not attempt to recapture it, and for a moment they regarded each other defensively. He had avoided the mistake of mistakes for thirty-six years, and the very flavour of romance about his experience with this woman made him wary. She had been mistaken twice and had ordered her imagination to sleep. Something within him pulled her, but none knew better than she the independent activity of sex. Still, like all women, fire was dear to her fingers. His eyes had a gleam in them which made her experience keenly the pleasurable sensation of danger.

“Did you know that night that I had forgotten our conversation in the tower?” he said, laughing uneasily. “Well, I will admit that I had, but I certainly remember the conversation in the elm walk—every word of it. It was a singular conversation,” he continued hurriedly. “I have not found her yet, by the way. What is love, anyhow? Something always seems to be lacking. I have wanted a good many women, but there were shallows somewhere.”

Patience had taken a chair and was fanning herself slowly. She answered with a judicial air, as of one deciding some abstract point to which she had given exhaustive study: “The lack is spiritual emotion. People of strong natures who are really in love are shaken by a passion that for the time being demands no physical expression. It is only when it subsides, in fact, that the other manifests itself. On the other hand, the unimpassioned, the physically meagre, are incapable of even imagining such an exaltation of emotion. It is the supreme convulsion of mystery. And it must be impossible to feel it more than once in a lifetime—for more than one person, I mean.”

“Have you ever felt it?” he asked abruptly. He was sitting opposite her, his brows drawn together, regarding her intently. Her cool impersonality nonplussed him.

“No.”

“Then how do you know?”
