Fire Cracker, The PJ Gray Series

PJ Gray plays a high-stakes game of computer cat-and-mouse—with a man who doesn’t exist
Someone has hacked into the St. Louis Hospital, and not merely to steal information. The hacker alters patient results and drug dosages in the hospital’s computer network, with fatal consequences. Who better for the police to have on the case than PJ Gray, psychologist and master of forensic computer simulation? As Gray gets to work with her old-school partner Leo Schultz, the pair discover the killer’s trail to be far more opaque than usual: They’re chasing someone who’s successfully manufactured his own death. When they start to untangle his plot, they become part of it, as the brilliant murderer puts Gray to the toughest test she’s ever faced.  An outstanding follow-up to Gray Matter, and featuring a techno-hunt worthy of Patricia Cornwell, Fire Cracker sizzles with suspense.
