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in the panel of the door that fitted so perfectly into an opening that Joe did not observe its presence before, was withdrawn and from behind a heavy wire screen a pair of glistening, suspicious eyes searched their faces, and then a voice demanded what they desired.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." Joe could distinctly hear the same person who had carefully replaced the shutter over the once more invisible spy-opening unbolt, then unlock and finally slowly open the door, and after she, a middle-aged woman, had again most suspiciously scanned the features of her visitors, she permitted Slippery and Joe to slip within the slightly opened door, that she promptly shut, and then bolted and carefully locked, as if the flat, instead of a home for human beings was a safe-deposit vault of an immensely rich bank.
"Hello, Marie," Slippery addressed the woman after she had tried the door knob to assure herself that the steel sheeted door was as correctly closed as before she opened it, "how are you and the rest of the gang ?" And while they shook hands Joe looked about in the semi-darkness of the hallway trying to see some members of the gang Slippery had spoken about when he inquired of Boston Frank as to their whereabouts, and about whom he had just repeated the question, which to Joe seemed odd because there was not a sound to be heard in the flat, that, as it was supposed to be the home of a "gang", should have at least shown these signs of human habitation.
After the woman and Slippery had exchanged other brief greetings all three went towards the rear of the hallway, and here she opened a door and bade them enter, and by the brilliant illumination they saw it was the dining room of the fiat.

Around its well provisioned dinner table were seated a number of men and women who in a most friendly, but noise avoiding manner, greeted Slippery and while they questioned him as to his latest movements, they gave Joe a chance to recover from the surprise that completely shocked him, when he discovered that this strangely secluded flat was the home of seven men and four women, all of the latter--with the exception of the woman who had opened the door--being barely more than young girls.
