Bernadette Saint Clare is an FBI agent with a difference: she sees through the eyes of killers but her ability makes her a dangerous maverick in the Federal Bureau of Investigations. Her reward is a backwater posting to Minnesota, but on her very first day a mutilated body is found: the killing is the work of a vigilante killer intent on settling old scores. Soon more bodies appear up and down the Mississippi. All are evildoers who have preyed on the innocent -- the murderer is literally interpreting the Old Testaments injunction, a life for a life. He will take as many as he can and quickly as he can before he can be stopped. Forensic investigation is too slow for the dizzying sequence of events that now take place. Bernadette is catapulted from the heart-stopping sequence of slayings into a chase where stalker and prey swap places and where her visions will take her to the very brink of sanity.
