"I will pay for a day in advance," said Greg, who had no wish to cheat the hotel out of its just dues.

"Thank you, sir. Two dollars."

Greg was shown to his room. He let the boy go and made a little reconnoissance. His own room looked upon the side street. Number 318 he found was at the end of the same corridor on the other side. It was evidently from its position a corner room with a window on the court and other windows to the west. There was a red light outside the door, indicating that the room possessed a fire escape. Around the corner of the corridor, opposite the elevator, was a window on the court, from which Greg could command the court window of de Socotra's room. The fire escape was outside the court window; moreover the window itself was open. Greg saw that the room might be reached without especial difficulty from five other rooms, i.e. one on the same floor, two above and two below.

He returned to the office. "You haven't a room opening on a fire-escape have you?" he asked the clerk. "I'm a bit nervous about fire in an old building like this."

The clerk consulted his plan. "No," he said. "Those rooms go first. But 316 on your floor is vacant. The fire-escape is adjoining. From the window you could reach out and put your hand on it if there was any need."

"Very well, change me to 316," said Greg, suppressing the desire to thank the amiable clerk who so innocently played into his hand.

Alone in 316 Greg narrowly searched all the windows on the other side of the court. No head was to be seen at any one of them. He reassured himself with the thought that at half-past eleven in the morning in a transient hotel there was not much reason for the guests to be in their rooms. There was a certain risk of course, but that must be taken.

He raised the window of his room to its widest extent and stood back to make sure for the last time that no one was watching him. Then grasping the rail of the fire escape he swung himself over, threw up the window of the adjoining room and slipped in. In all he was not visible above five seconds. Having made the trip he looked sharply behind him, but still no startled face appeared at any window within view. He breathed more freely.

Bolting the door into the hall, he took stock of his surroundings. There was no question but that he was in the right room, for the old suit-case with the collapsible side lay open on the floor, with de Socotra's more elegant valise beside it. The suit-case had been ransacked, but not unpacked. It contained only what an old gentleman of modest tastes might carry on a journey. De Socotra's own things were spread on the bureau and hung in the closet, a bit of stage business for the benefit of the maids, Greg supposed, for it was not likely that the elegant de Socotra troubled this modest room much.

Swiftly and silently Greg made his search. It did not take long, for the room offered but few possible places of concealment; valises, bureau drawers, closet. Greg did not neglect the bed; but no little black book rewarded him. He went over everything twice, taking care to leave all exactly as he had found it. His disappointment was keen. All that thought, not to speak of the risk, deserved a better reward he told himself.
