"Not yet—at least, not for certain. There's only one real method available; these questions will get us nowhere. We'll have to psychoanalyze you, young man."

"I don't care what you do, if you can offer any hope!" he declared vehemently. "Let's get it over!"

"Not as easy as all that!" rumbled Horker. "It takes time; and besides, it can't be successful with the subject in a hectic mood such as yours." He glanced at his watch. "Moreover, it's after midnight."

He turned to Nicholas Devine. "We'll make it Saturday evening," he said. "Meanwhile, young man, you're not to see Pat. Not at all—understand? You can see her here when you come."

"That's infinitely more than I'd planned for myself," said the youth in a low voice. "I'd abandoned the hope of seeing her."

He rose and moved toward the door, and the others followed. At the entrance he paused; he leaned down to plant a brief, tender kiss on the girl's lips, and moved wordlessly out of the door. Pat watched him enter his car, and followed the vehicle with her eyes until it disappeared. Then she turned to Horker.

"Do you really know anything about it?" she queried. "Have you any theory at all?"

"He's not lying," said the Doctor thoughtfully. "I watched him closely; he believes he's telling the truth."

"He is. I know what I saw!"

"He hasn't the signs of praecox or depressive," mused the Doctor. "It's puzzling; it's one of those functional aberrations, or a fixed delusion of some kind. We'll find out just what it is."
