Gray Matter

The riveting first entry in the acclaimed PJ Gray series, in which a police psychologist uses virtual reality forensics to solve a vicious series of homicides Penelope Jennifer “PJ” Gray is a recently divorced single mother living in St. Louis—and a psychologist turned cyber-profiler who heads the police force’s Computerized Homicide Investigations Project. By using virtual reality technology, Gray is able to get inside the heads of killers and reconstruct their crimes. The action begins when a talented pianist is savagely murdered, his back carved with a drawing of a dog, his head missing. As similar deaths follow, Gray and her partner—an old-school, technophobe detective named Leo Schultz—must use their skills to trace the serial murderer. Gray Matter marks a brilliant crime-writing debut, as this electrifying story recalls Thomas Harris’s Hannibal Lecter novels.
