Thus they went, the followed and the follower, down Broadway, when, the building of the New York Life being reached, the young man suddenly turned into it with quickened pace. Patsy broke into a sharp run. He quickly appreciated the danger he was in of losing his man. It seemed to him that these great big buildings, with their numerous elevators, many stairs and entrances and exits, were especially contrived to favor escaping crooks. As he dashed through the entrance, he saw his man turning, on a run, into the rotunda, which is circled by elevators. “The deuce!” cried Patsy. “My one chance is that he can’t get an elevator before I get to him.” He ran like a deer down the long corridor, to the amazement of those who were passing. He turned the corner just in time to see the gates of the elevator close, as it shot upward, and in it was the man he had followed. This was almost too much for Patsy, and he gave an exclamation of chagrin. But he rapidly took in the fact that the elevator that had just gone up was the one that did not stop short of the tenth floor, and that one was to follow, stopping at each. Into this he plunged, concealing himself from view, but in such a way that he himself could watch. Passing the ninth floor, he saw the young man eagerly watching the elevator that followed. Patsy could not get out on the ninth, but he did on the tenth, and hurried down the stairs. Some one was descending the stairs to the eighth floor. Leaning over the balustrades, Patsy saw a man descending rapidly. This one wore a dark beard and mustache, and his hair was of the same color. The man he had followed had been beardless and his hair was quite light. But there was something in the carriage of the shoulders of the man descending the steps that suggested the one he had followed down Broadway. Springing to the head of the stairs, Patsy flung himself on the balustrades, sliding down thence to gain time. The man followed quickened his pace and fairly flew down the steps two at a time. Patsy was gaining on him, for he was more reckless in his pursuit than the man was in his flight—taking more chances. Thus the chase continued until the floor on which the great offices of the insurance company were reached, when the followed man plunged into them, with Patsy close on his heels. Then the man stopped, faced about and waited for Patsy to come up. To the lad’s astonishment, he was not in disguise. He looked at Patsy with a sarcastic smile, and asked: “Are you following me?” “Yes,” replied Patsy, carefully sizing up his man. “You could be in better business,” replied the other. “What are you doing it for?” “You know very well,” replied Patsy. “Now that you have got up to me, what are you going to do?” he asked. That was just exactly what Patsy was asking himself. What was he going to do? But he made a bluff, and said: “I am going to find out who you are, and what your name is.”
