Back from the dead. That's how it feels for Nan Vining, a Pasadena homicide cop determined to find the brutal madman who attacked her a year ago. Nan's daughter calls the unknown assailant T. B. Mann--The Bad Man. On the job, Nan breaks rules and steals evidence, building a case file based on the certainty that T. B. Mann is obsessed with women who wear uniforms, that he hunts them, kills them, then adorns them with a pearl necklace.
At the crime scene of her official assignment, the murder of an ex-con, Nan spots a graffiti tag and is sure, against all reason, that T. B. Mann was there, too. Further complicating matters is Nan's developing relationship with Detective Jim Kissick, but she knows that opening her heart means losing control. Then T. B. Mann reemerges from the shadows for a final confrontation, bringing Nan to the sudden, horrifying realization that her killer has baited the perfect trap.
