With Mickey's help, Castle poses as an anonymous blackmailer and arranges for Glass to be at certain places while planting Livia's car in the same location, and ultimately placing one of Livia's earrings in Glass's bed. When Saint finds the earrings, he stabs Glass to death and, despite her protest that Glass was gay, accuses Livia of having an affair with his best friend. He throws Livia off an overpass onto a railroad track, where she is run over by a train. With Saint despondent, Castle assaults Saint's club and kills every member of his mob, including his remaining son John. Saint escapes the building albeit wounded. Castle pursues him and shoots him in a duel. As Saint lies dying, Castle reveals his schemes that led Saint to kill his friend and wife. He ties Saint to a car and sends it into the club's parking lot which is rigged with explosives. Saint dies in the ensuing explosion.
