The story
“At a large dinner-dance given by Mrs. Ralph Schuyler, the hostess discovers that her jewels have been stolen. Suspicion points to the governess of her child, and the young woman is about to be arrested, when a well-dressed stranger comes forward, confesses to the theft, and produces the gems from his pocket. Another guest shows a police shield and, introducing himself as Sergeant Wilson, handcuffs the confessed thief and leads him away. On the street Wilson explains to his prisoner that he is himself a crook, whose game is to pose as a police-detective in order to help out other thieves. The next instant, the ‘prisoner’ springs forward, handcuffs snap, and Wilson finds that the tables have been turned. Blowing a police whistle, his captor summons help—and ‘Sergeant Wilson’ learns that not only may thieves masquerade as detectives, but that detectives may also pose as thieves; and that by turning against him his own weapons, the cleverest detective in the city has drawn him into a trap.”
