A beautiful young woman's corpse is found dumped in a garbage-strewn alley. Now laid out in the office of medical examiner Kat Novak is an unidentified body that betrays no secrets -- except for a matchbook clutched in one stiff hand, seven numbers scrawled inside. When a second victim is discovered, Kat begins to fear that a serial killer is stalking the streets, using a deadly drug to do his dirty work. The police are skeptical. The mayor won't listen. One of the town's most prominent citizens, with a missing daughter of his own, is also Kat's chief suspect. As the death toll rises, Kat races to expose a deadly predator who is close enough to touch her.
