Episode 16 of Twin Peaks, "Arbitrary Law," originally aired on December 1, 1990, and was directed by Tim Hunter. This episode features the elusive elements of Cooper's dream from Episode Two finally coming together to crack the case. The evidence shows that Maddy's killer was the same as Laura's, and Albert Rosenfeld and Deputy Hawk show faith in Cooper's declaration that he needs 24 hours to solve the investigation. Meanwhile, the secret identity of Mr. Tojamura is revealed to Ben, only after he signs over the mill and Ghostwood estates. Seeking the connection between the magical boy and Harold Smith's suicide note, Donna visits Mrs. Tremond's house with Agent Cooper and Andy. She receives an envelope with a page from Laura's secret diary that reveals Laura and Cooper had the same dream. Cooper then stages a confrontation at the Roadhouse with suspect Ben and the help of Ed and Hawk. Truman brings Leland, Bobby brings Leo, and Major Briggs arrives unexpectedly with the old waiter. As his visions become clearer, Cooper remembers Laura's message from his dream and the Giant gives him back his ring. The final chaotic conclusion at the Sheriff's office officially answers the question of who killed Laura Palmer.
