The final cliffhanger episode of the first season of Twin Peaks, entitled "The Last Evening," originally aired on May 24, 1990, and was written and directed by series co-creator Mark Frost. James (James Marshall) and Donna (Lara Flynn Boyle) search for clues and find the missing tape, while Dr. Jacoby (Russ Tamblyn) gets assaulted and ends up in the hospital. Agent Cooper's (Kyle MacLachlan) undercover operation at One-Eyed Jacks is successful in setting up and arresting Jacques Renault (Walter Olkewicz), who confesses details about the night of Laura's murder. Also at One-Eyed Jacks, Audrey's secret investigation is almost discovered when her father, Ben Horne, unwittingly goes to visit "the new girl." The end is near for the Packard Sawmill, as Leo Johnson (Eric Da Re) prepares to burn it down with Shelley and Catherine inside. Hank Jennings (Chris Mulkey) reveals details of his criminal history, as well as his secret connection to Josie Packard. With several characters meeting their fate in this episode, including the two main suspects (Jacques and Leo), the mystery of Laura Palmer's murder is even more puzzling. The season finale ends with Agent Cooper receiving a gun shot in his room at the Great Northern Hotel.
