"Hello, Slippery, old boy, when did you find your way back to Chicago?" were the first words of the stranger's greeting, who acted as if he were greatly pleased with the return of Joe's pal to the "Windy City." "I too am glad to be once more where one's eyes do not tire looking into nothingness, bounded only by the horizon and the blue sky," answered Slippery, and then in a whisper, he added: "Say, Boston Frank, give me a square tip where Bunko Bill's gang is, so I can find a temporary hangout until I get straight as to the lay of the land." "Oh, is that what you wish to know, Slippery? Well they are in a private flat on South Clark, just below LaSalle Street, second house from the corner, on the fifth floor, and a dandy place at that, but," here he paused and with an ill-disguised look of resentment he stared at Joe and then queried: "Slippery, whose boy have you toting along with you?" And as Slippery did not promptly answer him he added with contempt in his voice, "I always understood that only a low-lived plinger dragged a road kid about with him and never a proper crook." Then to Joe's terror, he heard the man whom he had until this moment taken to be as honorable as his own late father answer: "Boston Frank, this lad is the wisest and shrewdest young crook that ever walked the streets of Chicago." This explanation pleased Boston Frank, who now asked Slippery to introduce him to the lad, which the former did, using his new nickname, "Dakota Joe." Listening to their further conversation, to his horror Joe became for the first time aware that Slippery was not a man looking for an honest job, but a criminal whose dislike for the police, which he had so openly manifested, was the natural result of the life he had been leading. Joe decided to keep this unpleasant discovery to himself, as he was a penniless lad in the center of an immense city. When they parted company with Boston Frank, Slippery and Joe found the house that he had described to be the "gang's" hangout, and after they had climbed five flights up a narrow stairway, Slippery rang the door bell of a flat. A shutter in the panel of the door that fitted so perfectly into an opening that Joe did not observe its presence before, was withdrawn and from behind a heavy wire screen a pair of glistening, suspicious eyes searched their faces, and then a voice demanded what they desired. Instead of an answer Slippery gave some differently sounding knocks upon the panel above the screened opening and whispered, "It's I, Slippery, the yegg."
