During an excursion in the park, the daughter of a diplomat was killed. Policeman Milo Sturgis and his friend psychoanalyst Alex Delaware are faced with a question: why was she killed? There were no signs of a struggle or signs of rape. The diplomat seeks to control the progress of the investigation. Milo and Alex wonder if the father really wants to bury the truth about her death along with his daughter’s body. Tying together the threads stretching from the death of a child to new victims, the author creates a portrait of Evil that is chilling with its realism.
