A gruesome triple homicide attracts the interest of Detective Inspector Joona Linna, who demands to investigate the murders. There's only one surviving witness--the boy whose family was killed before his eyes. The boy was supposed to to be the fourth victim, but somehow he survived. He's suffered more than one hundred knife wounds and lapsed into a catatonic state. Desperate for information, Linna enlists Dr. Erik Maria Bark to hypnotize the boy, hoping to uncover the killer through his memories.

Bark has sworn he would never do this kind of work again because of the long-term effects it can have on a patient's psyche. But Linna won't relent, and the doctor breaks his promise. When he hypnotizes the victim, a long and terrifying chain of events comes to light. This sensational thriller will have you mesmerized from its very first page.
