The Girl with the Dragon Tattoo

In the corporate archives, Salander discovers a photo of Martin and realizes that he is the one Harriet saw during the parade and is responsible for the murder in Uppsala. She heads back to the empty cabin and, through the surveillance recording, she witnesses Blomkvist leave and Martin trying to enter the cabin with an older set of keys before turning away.

Back in the basement, Martin boasts to Blomkvist that he has continued the serial killings that his father, Gottfried, began. Gottfried also sexually abused Martin and initiated him as a spectator to the murders when he was 14. Blomkvist asks him why he murdered his sister, and Martin admits that he planned to kill Harriet but was stranded in Hedestad; he does not know what happened to her. Frustrated that Blomkvist has no information on Harriet, Martin ties a leather noose around him and strips him of his clothes. To Martin’s surprise, Salander enters the basement and attacks him with a golf club. She releases Blomkvist and chases Martin as he runs away. Following his car on her motorbike, Salander watches as Martin steers his car towards an oncoming truck. He dies in the crash, and Salander returns to Blomkvist with the news.
