Snipes was a very good trailer. He was so little that no one ever noticed him, and he could keep a man in sight no matter how big the crowd was, or how rapidly it changed and shifted. And he was as patient as he was quick, and would wait for hours if needful, with his eye on a door, until his man reissued into the street again. And if the one he shadowed looked behind him to see if he was followed, or dodged up and down different streets, as if he were trying to throw off pursuit, or despatched a note or telegram, or stopped to speak to a policeman or any special officer, as a detective might, who thought he had his men safely in hand, off Snipes would go on a run, to where Alf Wolfe was waiting, and tell what he had seen. Then Wolfe would give him a quarter or more, and the trailer would go back to his post opposite Case's tenement, and wait for another victim to issue forth, and for the signal from No. 8 to follow him. It was not much fun, and “customers,” as Mr. Wolfe always called them, had been scarce, and Mr. Wolfe, in consequence, had been cross and nasty in his temper, and had batted Snipe out of the way on more than one occasion. So the trailer was feeling blue and disconsolate, and wondered how it was that “Naseby” Raegen, “Rags” Raegen's younger brother, had had the luck to get a two weeks' visit to the country with the Fresh Air Fund children, while he had not. He supposed it was because Naseby had sold papers, and wore shoes, and went to night school, and did many other things equally objectionable. Still, what Naseby had said about the country, and riding horseback, and the fishing, and the shooting crows with no cops to stop you, and watermelons for nothing, had sounded wonderfully attractive and quite improbable, except that it was one of Naseby's peculiarly sneaking ways to tell the truth. Anyway, Naseby had left Cherry Street for good, and had gone back to the country to work there. This all helped to make Snipes morose, and it was with a cynical smile of satisfaction that he watched an old countryman coming slowly up the street, and asking his way timidly of the Italians to Case's tenement. The countryman looked up and about him in evident bewilderment and anxiety. He glanced hesitatingly across at the boy leaning against the wall of a saloon, but the boy was watching two sparrows fighting in the dirt of the street, and did not see him. At least, it did not look as if he saw him. Then the old man knocked on the door of Case's tenement. No one came, for the people in the house had learned to leave inquiring countrymen to the gentleman who rented room No. 8, and as that gentleman was occupied at that moment with a younger countryman, he allowed the old man, whom he had first cautiously observed from the top of the stairs, to remain where he was.
