Green’s Dictionary of Slang

used attrib. in combs. below referring to a confidence game carried out in a brothel, supplied with false panels that permitted access to the prostitute’s room so that the client could be robbed or beaten up; note James D. McCabe, Secrets of a Great City (1868): ‘panel thieving. This method of robbery is closely connected with street walking. The girl in this case acts in concert with a confederate, who is generally a man. She takes her victim to her room, and directs him to deposit his clothing on a chair, which is placed but a few inches from the wall at the end of the room. This wall is false, and generally of wood. It is built some three or four feet from the real wall of the room, thus forming a closet. As the whole room is papered and but dimly lighted, a visitor cannot detect the fact that it is a sham. A panel, which slides noiselessly and rapidly, is arranged in the false wall, and the chair with the visitor’s clothing upon it is placed just in front of it. While the visitor’s attention is engaged in another quarter, the girl’s confederate, who is concealed in the closet, slides back the panel, and rifles the pockets of the clothes on the chair. The panel is then noiselessly closed. When the visitor is about to depart, or sometimes not until long after his departure, he discovers his loss’.
