When Jimmy Marcus's daughter is found murdered, Sean Devine is assigned the case. His investigation brings him into conflict with Marcus, who finds that the old methods of his criminal past tempt him to solve his daughter's murder in a much more brutal and satisfying way than the law ever could. And then there is Dave Boyle, who came home the night Jimmy's daughter died covered in someone else's blood. Dave's wife, Celeste, begins to doubt her husband's story and perceive a second, darker personality behind Dave's bland façade. His personal life unravelling, Sean Devine must go back into a world he thought he'd left behind to confront not only the violence of a neighbourhood on the brink of riot, but also the nightmares of his irrevocably marked past.
