"What will you do," exploded the doctor, "when she wakes up and finds how you have cheated her? When she realizes, too late, that she has sold her birthright?"

The professor rose slowly and dusted the dry grass from the knees of his knickers. "Tut, tut!" he said, "the subject excites you. Let us talk about me for a change. Observe me carefully, John, and tell me what you think of me. Only not in marine language. Am I an Apollo? Or a Greek god? Or even a movie star of the third magnitude? Or am I, not to put too fine a point on it, as homely as a hedge fence?"

"Oh, hang it, Benis, stop your fooling."

"I'm not fooling. I want you to understand that I have consulted my mirror. And I know just how likely I am to appeal to the imagination of a young girl. I take my chance, nevertheless. Your question, divested of oratory, means what shall I do if Desire finds her mate and that mate is not myself? My answer, also divested of oratory, is that I do not keep what does not belong to me. Is that plain?"

The doctor nodded. "Plain enough," he said. "But how will you know?"

"Well, I might guess. You see," resuming his seat and his ordinary manner at the same time, "Desire is my secretary. I make a point of studying the psychology of those who work with me. And, aside from the slight abnormality which I have mentioned, Desire is very true to type, her own type—a very womanly one. And a woman in love is hard to mistake. But," cheerfully, "she is only a child yet in matters of loving. And she may never grow up."

"You seem quite happy about it."

"'Call no man happy till he is dead.' And yet—I am happy. If tears must come, why anticipate them?"

"There speaks the hopeless optimist," said Rogers, laughing. "But because I called you a fish, I'll give you a bit of valuable advice. I can't see you scrap quite all your chances. Kill Mary."

"I can't. Besides, why should I? Desire likes to hear about her. Or says she does. It provides her with an interest. And a little perfectly human jealousy is very stimulating."
