A thrilling detective novel that begins with a horrific crime against a father, mother, and their young daughter. The perpetrator dismembers their bodies, and the teenage son is found critically injured, while the eldest daughter is nowhere to be seen. Detective Jona Lina seeks the help of psychiatrist Erik Maria Park, who retired from hypnosis 10 years ago, fearing for the life of the young daughter, whom he believes the killer wanted to exterminate her entire family. The doctor agrees to hypnotize the survivor of the massacre to find out what happened and who the perpetrator is. Hypnosis succeeds in identifying the perpetrator, but a series of problems and misfortunes follow the doctor from then on. The media and public opinion revolt against his hypnotizing a severely injured underage boy, and his teenage son, who suffers from hemophilia, is kidnapped from home, and even a slight hemorrhage can be fatal.
