The Girl with the Dragon Tattoo Summary: The Full Story
SPOILERS: This section details the entire plot, including the ending.
Mikael Blomkvist is convicted of libel against billionaire Hans-Erik Wennerström. His reputation is ruined. He steps down from his magazine, Millennium.
Soon after, he receives an unusual offer. Henrik Vanger, an aging industrialist, wants to hire him. The job is not to write a family history, as is first stated.
Henrik’s real goal is for Blomkvist to investigate the disappearance of his great-niece, Harriet Vanger. She vanished in 1966 from the family’s isolated island.
The only clue is a pressed flower Henrik receives each year. Blomkvist accepts the assignment. He moves to a cottage on Hedeby Island.
Meanwhile, Lisbeth Salander is introduced. She is a young, antisocial, but brilliant hacker. She works as a researcher for a security firm. Salander is under state guardianship. Her new guardian, Nils Bjurman, is a sadist. He brutally rapes her.
Salander does not go to the police. She plans her own revenge. She tasers Bjurman, restrains him, and tattoos a confession on his chest. She blackmails him to gain control of her own life and finances. This subplot runs parallel to Blomkvist’s investigation.
Back on the island, Blomkvist finds a breakthrough. He decodes numbers in Harriet’s old datebook. The numbers refer to verses in the Book of Leviticus. The verses describe punishments for sexual sins. He realizes the initials next to the numbers are victims of a serial killer.
Blomkvist hires Salander to help with the research. She joins him on the island. They become lovers. Their investigation points to the Vanger family.
They discover that Harriet’s father, Gottfried, was a killer. But the murders continued after his death. They look for an accomplice.
The killer becomes aware of their progress. They are threatened. A cat is left mutilated on their porch. Blomkvist is shot at while jogging. The case comes to a head when Blomkvist goes to Martin Vanger’s house.
Martin, Harriet’s brother, captures Blomkvist. He takes him to a torture chamber in his basement. Martin reveals he was trained by his father. He is the one who continued the murders. As Martin prepares to kill Blomkvist, Salander bursts in.
She attacks Martin with a golf club. Martin flees but dies when he crashes his car. Blomkvist and Salander do not call the police. They cover up their involvement. They need to find the truth about Harriet.
They discover Harriet is alive. She escaped her father’s abuse and her brother’s threats. Her cousin, Anita, helped her flee. Blomkvist travels to Australia to meet her. He convinces her to return to Sweden. She reunites with Henrik.
Blomkvist serves his prison sentence. He then learns Henrik’s evidence on Wennerström is useless. It is too old. But Salander has hacked Wennerström’s computer. She gives Blomkvist everything he needs.
Blomkvist writes an exposé that destroys Wennerström.
Salander also steals billions from his secret accounts. The story ends with Salander realizing she has feelings for Blomkvist. But she sees him with his long-time partner, Erika Berger, and walks away alone.
