Seeking a retired spot, in a corner, he made a rapid change in his appearance.
He had entered the building a smartly dressed young fellow. He left it looking like a broken-down man of sixty, limping in gait and with bowed shoulders, racked with a cough.
But he did not leave it until he had stood some time in the entrance holding out his hands and asking for money of every one that entered nor until he had been fairly driven from it by the officer in charge.
Then he stood on the sidewalk, still begging, and continued to do so until the officer drove him away by threatening him with arrest.
All the while he was thus engaged his eyes had been busy, and he saw a man standing on the opposite side of the street, occupying a position that commanded a view of the main entrance.
When driven from the sidewalk in front of the building he crossed the street and took up a position near this man.
A moment was sufficient to satisfy Patsy that he was disguised. Half an hour passed, during which Patsy begged, when he could without being discovered by policemen, and still shadowed the disguised man, who was watching the main entrance.
Finally this man strolled away like one who did so reluctantly. Patsy watched him with a thrill of delight.
He had found his man again.
The man went to a hotel, where he sat down in the writing-room and, taking paper and envelope from his pocket, began to write letters.
