Murder Theory

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.
