"'‘The Hypnotist’ is the stuff nightmares are made of. '"
Early one morning, Erik Maria Bark is woken from his bed. A call from the hospital requests his presence. A young boy has been admitted with stab wounds all over his body. His father, mother and sister have been brutally murdered. He is the only survivor. What they want from Erik is to hypnotise the boy quickly so that he can give the police some piece of evidence that lies deep in his subconscious: but Erik promised himself he would never hypnotise ever again and it is a promise he has kept for ten years - until tonight. As the truth emerges, Erik finds that he has made himself a target of this heinous crime.
A few days later, Erik’s son is kidnapped from the family home. His wife, Simone, was drugged and through the haze watched her son being dragged from the appartment. Is this kidnapping connected to the murders of this innocent family? With a medical condition that could be fatal to their son, Erik must find his boy - and quickly. Requesting the help of the detective investigating the murders, Joona Linna acts like the Rottweiler he is credited to be and is soon tracking down, possibly not one, but two serial killers.
