The lobby of the Harburger House was large, and gloomy in its old-fashioned black-walnut woodwork. Except for one man sitting at a desk by the window and writing industriously, and the clerk behind the counter, the lobby was untenanted. To the left a huge stairway led to the gloom above, for the hotel boasted no elevator except the huge “baggage lift,” which had been put in in the palmy days of the house, when the great river packets were still a business factor.

Philo Gubb walked across the lobby to the clerk’s desk. The industrious penman by the window glanced over his shoulder. He looked more like a hotel clerk than like a traveling salesman, but Philo Gubb gave this no thought. The clerk behind the desk put his fingers on his lips.

“Sh!” he whispered. “Are you Detective Gubb? Good! I’ve been expecting you. Have you a gun?”

“In my telescope case,” whispered Philo Gubb.

“Take this one,” said the clerk, handing the paper-hanger-detective a glittering revolver. “Be careful. Come—I’ll show you the room.”

He came from behind the desk and picked up Philo Gubb’s telescope valise and led the way up the dingy stairway. Luckily for Billy Getz’s great practical joke, Philo Gubb had never seen Jack Harburger, or he would have recognized him in the plump little man carrying his telescope valise. Up three flights of dark stairs, Jack Harburger led Philo Gubb, and at the landing of the fourth floor he stopped.
