Gray matter

PJ Gray, a newly single psychologist turned cyber‑profiler, leads St. Louis’s experimental Computerized Homicide Investigations Project, using virtual‑reality reconstructions to get inside a killer’s mind. When a gifted pianist is brutally murdered—and similar deaths follow—PJ and her old‑school partner, Detective Leo Schultz, race to track a serial killer whose methods are as disturbing as his motives. Gray Matter launches the PJ Gray series with a gripping blend of psychology, technology, and high‑stakes investigation. This electrifying story recalls Thomas Harris's Hannibal Lecter novels.
