A killer wants vengeance. An FBI agent wants justice. Bernadette Saint Clare is an FBI agent with a difference: she has the uncanny ability to see murders through the eyes of killers. Because of this second sight she has cracked some seemingly impossible cases...but her ability makes her a dangerous maverick in the staid environment of the Federal Bureau of Investigation. 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 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 Testament's injunction, 'a life for a life'. Torture and death are all his victims can hope for. 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.
