The Naturalist

Professor Theo Cray is trained to see patterns where others see chaos. So when mutilated bodies found deep in the Montana woods leave the cops searching blindly for clues, Theo sees something they missed. Something unnatural. Something only he can stop. As a computational biologist, Theo is more familiar with digital code and microbes than the dark arts of forensic sleuthing. But a field trip to Montana suddenly lands him in the middle of an investigation into the bloody killing of one of his former students.

Professor Theo Cray caught one of the most prolific serial killers in history using revolutionary scientific methods. Cut off from university research because of the shroud of suspicion around him after the death of his former student and the aftermath of catching his quarry, Cray tries to rebuild his life but finds himself drawn into another unsolved case. The desperate father of a missing child, ignored by the authorities and abandoned by his community, turns to Theo for help. The only clues are children's drawings and an inner-city urban legend about someone called the Toy Man.

Computational biologist and serial-killer hunter Dr. Theo Cray receives an off-the-record request from the FBI to investigate an inexplicable double homicide. It happened at the excavation site where a murderer had buried his victims’ remains. In custody is a forensic technician in shock, with no history of aggression. He doesn’t remember a thing. His colleagues don’t even recognize the man they thought they knew. But an MRI reveals something peculiar. And abnormal.
