1975: In the blistering heat of an Atlanta summer, a killer prowls the street, searching for the weak, the vulnerable and the lost. Almost 40 years later, a young woman is found brutally murdered in a sordid high-rise apartment. The specifics of her death are detailed and macabre, but for Special Agent Will Trent they are startingly familiar, and can only mean one thing. Desperate to deny this might be happening to him, he is forced to return to the home he grew up in, to the grimy crime-ridden streets, to a childhood he has spent the best part of his adult life trying to avoid. As the tension on the inner-city streets starts to simmer, Will becomes convinced that the clue to the killings now, and in 1975, may lie in his own past; a past that he hates yet feels responsible for. And that the killer is much, much closer to him than anyone thought possible.
