Dave was very much disturbed and disappointed. There could be no doubt that the boy thief had escaped by the window route. It would probably be in vain to try to follow him now. Dave dashed out into the corridor and ran down the stairs, not waiting for the elevator.

The clerk was talking to a guest, polite and imperturbable. He simply inclined his head as Dave burst forth:

“Who is he?”
