Dead women should not show up in photos 14 years beyond the grave. But if anyone is likely to recognize Claire Lidman, it's her husband, Samuel. He brings the photo to Hans Rekke and Micaela Vargas. Their initial skepticism gives way to cautious belief. But where will this case lead them? Meanwhile, Rekke's daughter, Julia, has a new boyfriend she's determined to keep secret. When word gets out, Micaela's world collapses around her, and Rekke is forced to confront a nemesis from his youth. Plunging us back into the political upheaval and financial crisis of the 1990s, as the Iron Curtain is finally lifted, the second Rekke and Vargas investigation sees our heroes grapple with a fiendish case that affects them both in profoundly personal ways.

Professor Hans Rekke is a world authority on interrogation techniques, capable of dizzying feats of logic and observation. But he also has a fragile psyche that falls apart under pressure. Micaela Vargas is a street-smart police officer, the daughter of Chilean political refugees, who grew up in the projects on the outskirts of Stockholm and has two brothers on the wrong side of the law. She is tenacious and uncompromising, and desperate to prove herself to her fellow cops. Micaela needs Hans’ unique mind to help her solve the case of a murdered asylum seeker from Afghanistan. Hans needs Micaela to save him from himself. Together, they need to find the killer before they’re both silenced for good.

Mikael Blomkvist is trying to reach Lisbeth Salander --- the fierce, unstoppable girl with the dragon tattoo. He needs her help unraveling the identity of a man who died with Blomkvist's phone number in his pocket --- a man who does not exist in any official records and whose garbled last words hinted at knowledge that would be dangerous to important people. But Lisbeth has disappeared. No one is aware that at long last she has her primal enemy, her twin sister, Camilla, squarely in her sights. In the end, it will be Blomkvist --- in a moment of unimaginable self-sacrifice --- who will make it possible for Lisbeth to face the most important battle of her life and, finally, to put her past to rest.

When a sadistic gang leader nicknamed Benito starts to torture Faria, a young Bangladeshi prisoner, Lisbeth Salander finds it impossible not to intervene. Now a target of Benito and her gang, Salander's time in prison is further complicated by news from her old guardian, who tells her she may have been a subject in a secret experiment known as the Registry. She enlists her friend Mikael Blomkvist, crusading editor of Millennium magazine, to help her look into it. Once Salander is released, she devotes her time to uncovering the truth in the case that landed Faria in prison, and Blomkvist continues his search into Salander's background. But when the two cases start to dovetail, Salander and Blomkvist must join together to fight for justice and their lives.

June 8, 1954. Several English nationals have defected to the USSR, while a witch hunt for homosexuals rages across Britain. In these circumstances, no one is surprised when a mathematician by the name of Alan Turing is found dead in his home in the sleepy suburb of Wilmslow. It is widely assumed that he has committed suicide, unable to cope with the humiliation of a criminal conviction for gross indecency. But a young detective constable, Leonard Corell, who once dreamed of a career in higher mathematics, suspects greater forces are involved.

A genius hacker who has always been an outsider. A journalist with a penchant for danger. She is Lisbeth Salander, the girl with the dragon tattoo. He is Mikael Blomkvist, crusading editor of Millennium. One night, Blomkvist receives a call from a source who claims to have been given information vital to the United States by a young female hacker. Blomkvist, always on the lookout for a story, reaches out to Salander for help. She, as usual, has plans of her own. Together they are drawn into a ruthless underworld of spies, cybercriminals and government operatives --- some of whom are willing to kill to protect their secrets.
