Lars Kepler is the pseudonym of critically acclaimed husband and wife team Alexander Ahndoril and Alexandra Coelho Ahndoril, authors of the No. 1 internationally bestselling Joona Linna series. With seven installments to date, the series has sold 13 million copies in 40 languages. The Ahndorils were both established writers before they adopted the pen name Lars Kepler, and have each published several acclaimed novels.
In the frigid clime of Tumba, Sweden, a gruesome triple homicide attracts the interest of Detective Inspector Joona Linna, who demands to investigate the murders. The killer is still at large, and there’s only one surviving witness—the boy whose family was killed before his eyes. Whoever committed the crimes wanted this boy to die: he’s suffered more than one hundred knife wounds and lapsed into a state of shock. Desperate for information, Linna sees only one option: hypnotism. He enlists Dr. Erik Maria Bark to mesmerise the boy, hoping to discover the killer through his eyes.
It’s the sort of work that Bark has sworn he would never do again—ethically dubious and psychically scarring. When he breaks his promise and hypnotises the victim, a long and terrifying chain of events begins to unfurl.
