The fourth episode of Twin Peaks' first season, "The One-Armed Man," was originally broadcast on May 3, 1990, and directed by Tim Hunter (River's Edge). Deputy Andy Brennan sketches Sarah Palmer's visions of Killer Bob, resembling the Bob in Agent Cooper's dream from episode two. Another of Cooper's visions appears at a nearby motel, where Deputy Hawk (Michael Horse) finds the One-Armed Man (Al Strobel). Ben Horne and Catherine are also at the same hotel, making plans to burn the mill, while Josie spies on them. Agent Cooper questions the One-Armed Man, who claims to be named Philip Michael Gerard, about his connection to Bob. At the Double R Diner, Norma Jennings (Peggy Lipton) gets word that her husband, Hank Jennings (Chris Mulkey), is up for parole, and he is granted release after she defends him in court. Audrey Horne begs her father for a job at his department store, where Laura Palmer once worked. She plans to conduct her own secret investigation with the additional help of Donna Hayward. Leo Johnson's bloody shirt is found in Jacques Renault's apartment, while Leo and Ben make plans concerning the mill. Later that evening, Donna and James Hurley look for the other half of the gold heart necklace that they had buried. This episode features the voice of series creator David Lynch as Cooper's hard-of-hearing supervisor, Gordon Cole.
