This detective story is written in the genre of psychological Thriller. The author does not spare the reader's psyche and imagination, does not smooth out particularly harsh scenes, does not apply "retouching" to images of maniacs, describing methods of murder and victims. The result is a chilling picture of the criminal world, the dark side of the work of detectives and criminal experts, which is usually always hidden from people. It is hidden because it is simply unbearable for an untrained person to see all this and realize that maniacs are practically no different from ordinary people. You can't tell the difference. It lies in the thoughts of a maniac, in the way he looks at the world around him and at you and me. When choosing a victim…Two young women were killed. Each victim's body was pierced eight times by a thin non-metallic object. And pierced VERY SLOWLY. It was as if the killer was prolonging the pleasure of the murder process itself, causing the victim unbearable suffering.The investigation leads senior Lieutenant of the investigative police Department Valery Samsonov to the shelter where the deceased women were once brought up.What happened here many years ago? There were archives, lists of adoptive parents and... walls that witnessed horror, Vice and despair.
