A Manhattan Knight

John Fenton visits a fortune-teller to gain insight into his parentage. While there, a police raid occurs, and he climbs the fire escape to the apartment above. There he finds a girl standing over the body of a young man who has just shot himself. The girl, Belle Charmion, explains that her half brother, Gordon Brewster, had stolen some jewels from their uncle and, fearing that the police would capture him, had attempted suicide. Fenton conceals the brother in another room and impersonates him when the police arrive. Later, he and Belle take Brewster to his uncle's home. In the excitement, the jewels have been forgotten, and Fenton returns to search for them. By this time, the family butler, who is a member of an underworld gang, has tipped off his friends, who then steal the Fenton jewels. At the butler's home, a scuffle ensues; Fenton recovers the jewels and learns that he is actually a distant relative of the Charmions, having been kidnapped in infancy by a crook. With both mysteries thus resolved, Belle and Fenton become engaged.
