1989–1991 series At the start of the series, Horne is recruiting Norwegian businessmen to invest in his plans for Ghostwood, an elaborate country club and
planned community that would take the place of Twin Peaks' scenic Ghostwood Forest. His plans are interrupted when Laura Palmer, the daughter of Ben's lawyer, Leland Palmer, is found murdered. The murder both puts Leland out of commission and gives Audrey the opportunity to paint Twin Peaks as a dangerous place, frightening away her father's potential investors. As the first season progresses, Horne attempts to juggle his various personal and business problems in light of Laura's murder. While putting on a brave face and acting on behalf of the stricken Palmers to retrieve Laura's body and transport it for burial, Horne's vulnerability is revealed when Audrey confronts him with knowledge of his affair with Laura. Following Laura's funeral, Horne pours all of his energies into obtaining the Packard Sawmill land, some of the most valuable real estate in Twin Peaks. He hires local drug runner Leo Johnson to burn down the mill with Catherine trapped inside, and then obtains the services of hitman Hank Jennings to murder Leo so that no one will ever know the two worked together. Horne's plan goes terribly awry, though: The mill doesn't completely burn; Catherine's body is never found, which prevents Horne from collecting on her life insurance policy (a matter further complicated by Catherine having made an intentional clerical error to foil Horne in the event of her death); Leo survives being shot by Hank; and Audrey is kidnapped by the staff of One Eyed Jacks, who intend to use her to extort Horne for millions of dollars while simultaneously enacting a hostile takeover of the business. Horne begrudgingly gives Cooper the requested ransom money, then hires Hank to trail Cooper, kill everyone involved in retrieving Audrey, and bring back Audrey and the money himself. Ultimately, Cooper himself rescues Audrey and returns to Twin Peaks with both her and the money intact. Shortly after Audrey's safe return, a misunderstanding in a clue provided to Cooper by
Mike leads to Horne being arrested for the murder of Laura Palmer. Horne is left with the incompetent Jerry as his lawyer, his only advice being, "Get another lawyer." Simultaneously, Catherine Martell re-surfaces, alive and well, having survived the fire. Posing as a foreign investor, she first arranges for Horne to purchase the Mill Land and Ghostwood from Josie with a bogus check, and then blackmails him into signing over Josie's 50% to her in exchange for an alibi as to his whereabouts the night Laura Palmer was murdered. Desperate, Horne signs over his deed to Catherine, who then reneges on her promise to provide him an alibi. Horne is left trapped in jail, where he begins to break down and reminisce about his childhood. Eventually, Horne is used as a pawn to draw out the real killer; Cooper brings him to a meeting of suspects at the Roadhouse, which is also attended by the Great Northern's elderly room service waiter. The waiter, under the influence of
The Giant, identifies Leland Palmer, under the influence of the demonic spirit
Bob, as Laura's killer. In order to trap Leland, Cooper lies and tells everyone that he has positively identified Ben Horne as the real killer, and then gives Leland permission to accompany Horne to the jail to act as his counsel. Leland/Bob, unaware of the ruse, accompany Cooper and Horne to the jailhouse; just as Cooper and Sheriff Truman are about to lead Horne into an interrogation room, they hold him back and throw Leland/Bob inside, trapping him. The revelation shocks Horne, who can only mutter "Leland..." before he is allowed to go home. Horne slips into a deep depression before ultimately suffering a nervous breakdown and a psychotic break. He becomes convinced that he is
Confederate General
Robert E. Lee, leading the South in a victorious campaign against the Union. His psychiatrist, Dr. Lawrence Jacoby, theorizes that Horne is at least partially aware of reality, and that his fantasy is an attempt to reverse his recent misfortunes and start anew. Jerry, Audrey, and Bobby Briggs, under Jacoby's direction, serve to enable Horne's fantasy up to a surrender of the Union at
Appomattox. Horne suffers a blackout, from which he awakens with a desire to atone for his past sins, whilst simultaneously seeking peaceful revenge on Catherine. To meet both of these ends, he launches an environmentalist campaign to prevent Catherine from re-building the mill or building anything in Ghostwood; he learns that the forest is the habitat of an endangered species, the
"Pine Weasel", and manages to get the majority of the town on board to block any of Catherine's real estate developments. He makes a genuine attempt to atone for his past crimes, gives up smoking, and begins building a close relationship with Audrey, to whom he begins to teach the family business. As part of his "new life," Horne attempts to make amends with Mrs. Hayward, with whom he had an affair 17 years before, an affair which produced Donna Hayward; Ben wants to both make up for his indiscretions with Mrs. Hayward and get to know the daughter he never had. In the series finale, Horne comes to the Hayward home to reveal everything to a heartbroken Donna. Enraged, Doc Hayward, Donna's father, punches him, resulting in Horne splitting his head open on a piece of fireplace equipment.
2017 revival Benjamin Horne returns 25 years later in
the 2017 revival, where he is still the owner of the Great Northern. He and Sylvia appear to be acrimoniously divorced, and Johnny lives with Sylvia. Horne still wears his wedding ring and resists a flirtation with his secretary Beverly Paige, but agrees to date Beverly after a bitter argument with Sylvia. It is unknown whether he has a relationship with Audrey or Donna, as Audrey's whereabouts are unknown and Donna does not appear in the third season. He also employs
James Hurley as a security guard at the Great Northern. Horne is deeply troubled about his grandson Richard (Audrey's son), a violent and angry drug dealer. He cut off contact with Richard several years before the events of the third season. After Richard terrorizes Sylvia and Johnny and robs Sylvia's house, Sylvia asks Horne for money and threatens to call her lawyer if he does not comply. When Richard kills a young boy and brutally beats a witness, Horne pays the witness' medical bills and the cost of the boy's funeral. Although the fate of Ghostwood and the pine weasel campaign is not revealed in the show, the book
Twin Peaks: The Final Dossier reveals that Horne sold a portion of the land initially earmarked for Ghostwood to a
private prison. In addition, Horne helped his brother Jerry start a cannabis business, which reportedly tripled the Horne businesses' total revenue. ==Red herring for Laura's killer==
