The hypnotist
(Book)

Swedish Detective Inspector Joona Linna investigates the murders of three family members whose killing was witnessed by a fourth intended victim, a traumatized child whose shock Linna hopes to penetrate through hypnotism. Captivated by a triple homicide, Detective Inspector Joona Linna investigates the murder of a family as he searches for the oldest daughter who escaped the carnage but is reported missing. The only surviving witness is the intended victim -- the boy who watched his family be murdered after being stabbed over one hundred times. He is in no condition to be questioned and desperate for information, Linna enlists Dr. Erik Maria Barks to hypnotize the boy so she can discover what he saw.
