The episode opens with the murder of a young woman by someone standing in her closet. Mrs. Wolfe goes to see Peter Gunn and asks him to save her life, that her husband and his mistress are planning to kill her. Her husband is a well-known and successful lawyer in town. Evidence suggesting that Mr. Wolfe murdered the young woman (and that she was his mistress) mounts when Peter, who has been trailing Mr. Wolfe, finds him in the murdered woman's apartment and later finds a gift, apparently to the woman, with a note in Mr. Wolfe's handwriting. Peter eventually proves that Mrs. Wolfe has orchestrated the killing of the woman and framing of her husband in order to take his fortune and (possibly?) marry the man she hired to kill the woman.
