So meantime he took a stroll into Broadway and walked leisurely up and down that thoroughfare, pausing occasionally to make a trifling purchase and turning abruptly again and again in the attempt to discover who might be following him.

No one liable to be a detective of any sort could he discern; yet he was too shrewd to be lulled into a false belief that his each and every act was unobserved.
Mershone returned to his hotel, went to his room, and slept until after one o'clock, as he had secured but little rest the night before in his primitive quarters at the police station.

It was nearly two when he reappeared in the hotel restaurant for luncheon, and he took his seat and ate with excellent appetite.
During this meal Mr.Fogerty also took occasion to refresh himself, eating modestly at a retired table in a corner.

He remembered seeing this youth at breakfast, and thoughtfully reflected that the boy's appearance was not such as might be expected from the guest of a fashionable and high-priced hotel.
Silently he marked this individual as the possible detective.
