The Naturalist
4 primary works
Book 1
An Amazon Charts bestseller.
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. As more details, and bodies, come to light, the local cops determine that the killer is either a grizzly gone rogue…or Theo himself. Racing to stay one step ahead of the police, Theo must use his scientific acumen to uncover the killer. Will he be able to become as cunning as the predator he hunts—before he becomes its prey?

Book 2
A Wall Street Journal bestseller.
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.
To unravel the mystery behind the Toy Man, Theo must set aside his scientific preconceptions and embrace a world where dreams and nightmares carry just as much weight as reality. As he becomes immersed in the case, he discovers a far-reaching conspiracy—one that hasn’t yet claimed its last victim.

Book 3
The desire to kill is becoming contagious in this riveting novel of conceivable mad science by the Wall Street Journal bestselling author of The Naturalist.
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.
What on earth made him commit murder?
After discovering that a mysterious man has been stalking crime scenes and stealing forensic data, Cray has a radical and terrifying theory. Now he must race against time to find a darker version of himself: a scientist with an obsession in pathological behavior who uses his genius not to catch serial killers—but to create them.
