Before he reached Broadway Lawrence began to have doubts as to whether it really was a coincidence or not. Another man would have thought nothing of the matter; but Barry had lately been through an experience of shadowing which taught him many things about the methods of private detectives and others of their ilk, which had produced in him a habit of being constantly on guard.

At least it would do no harm to be sure, he thought, and, rounding the corner of Broadway, he hastened forward a few steps to the entrance of a moving-picture theater. Once within its shelter, he swiftly found a spot where the plate-glass windows of the ticket booth acted as an admirable reflector. Then, back squarely to the street, and eyes riveted on the improvised mirror, he leisurely undid his fur coat, as leisurely produced a cigarette from his case, and hunted for his match box.

It was just as he struck a light that his patience was rewarded. In the glass he saw the stranger steal silently into view around the corner, hesitate for the fraction of a second, then, catching sight of Barry's back, as softly withdrew out of sight.

"So that's your little game, is it?" Lawrence reflected, with a grim smile, as he lighted the cigarette with care, and flicked the match into the street. "Looks as if there might be a bit of fun in this."

Buttoning his coat, he started briskly down Longacre Square, swinging his stick with the air of a man who was just beginning a constitutional. In front of the Astor he paused a second, as if half minded to enter the brilliant hostelry. Then, without warning, he turned abruptly, stepped into the street, and headed for the Times Building. As he did so he caught a glimpse, out of the corner of his eye, of his pursuer, half a block in the rear.

With a chuckle of amusement, Barry passed the outdoor subway entrance, and walked swiftly into the lower floor of the building. The instant he was inside, he hastened his steps, hurried past the stairs leading down into the underground road, pushed his way through the throng which crowded the big drug store that occupied the ground floor, and emerged on Forty-second Street.

A crosstown car was just getting up speed as he dashed across the street; and with some difficulty he raced forward and swung himself aboard. A backward glance showed that his bearded friend was nowhere in sight, and Lawrence smiled again.

Nevertheless, he did not relax his vigilance. Making his way through to the front of the car, he sat down on one of the little seats just behind the motorman, and made no attempt to alight until Madison Avenue had been reached. Here he slipped off, dodged around the front of the car, slid across the slippery pavement, and was engulfed in the comparative shadow of the Manhattan in an instant.

The three blocks to Forty-fifth were passed in as many minutes. Around the corner of the cross street, however, he sought a secluded doorway, and waited patiently for as much as five minutes, with the pleasant, ever-growing conviction that his man had been eluded.

"Not quite clever enough, my friend," he murmured, as he crossed the dark and rather silent street, heading for the bright entrance of the St. Albans near Fifth Avenue.
