Complete story — includes the ending

Lester erases evidence of his presence from the scene of Linda's murder before anonymously calling the police to report gunshots. The police discover Linda's body and question Lester before releasing him. Molly's father Lou, a retired cop turned coffee shop owner, tells Gus that Malvo may be back in Bemidji. Gus later spots Malvo exit a cabin and drive away. Budge and Pepper drive Lester home, unaware that Malvo is following them in a car stolen from a dealership. The agents remain on watch outside Lester's house, but Malvo ambushes and kills them both. Lester hides from Malvo and sets a bear trap in his bedroom that maims Malvo's leg, forcing him to flee the house. Malvo returns to his cabin to treat his injury, but Gus surprises Malvo and, just before the latter can try to speak, Gus shoots him in the face and kills him. He later shows Molly a briefcase containing Malvo's various tape recordings, including that of Lester confessing to killing Pearl. Two weeks later, police track Lester to Montana, where he attempts to flee, only to fall through thin ice to his death. Molly is informed of the scene at home, where she and Gus celebrate the end of the case.
