The hypnotist

Karolinska Hospital, Stockholm. Detective Inspector Joona Linna is faced with a boy who witnessed the gruesome murder of his family. He's suffered more than one hundred knife wounds and is comatose with shock. Linna's running out of time. The killer's on the run and, seemingly, there are no clues. Desperate for information, Linna enlists disgraced specialist Dr Erik Maria Bark, a hypnotist who vowed never to practice again. As the hypnosis begins, a long and terrifying chain of events unfurls with reverberations far beyond Linna's case.
