A sheet of paper, propped against the mirror of the dresser attracted her eye. As she unfolded it, she saw at once that the handwriting was Jerry’s.

“I’m too healthy a pup to stay in bed,” he had scrawled. “Sorry, but I’m walking out.”

Penny handed the note to Miss Brent who could not hide her annoyance as she read it.

“Nothing like this ever happened before!” she exclaimed. “How could the young man have left this floor and the building without being seen? He’s in no condition to be wandering about the streets.”

“Then Jerry really did need hospitalization?” inquired Penny.

“Certainly. He suffered shock and the doctor was afraid of brain injury. The patient should have been kept under observation for at least twenty-four hours. Wandering off this way is a very bad sign.”

“We’ll get him back here pronto!” Salt promised. “He can’t have gone far.”

In the lobby he and Penny paused to ask the receptionist if she had observed anyone answering Jerry’s description leave the building.

“Why, no,” she replied, only to correct herself. “Wait! A young man in a gray suit left here about twenty minutes ago. I didn’t really notice his face.”

“That must have been Jerry!” cried Penny. “Which way did he go?”
