There are threads in our lives. You pull one, and everything else gets affected.
When they were children, Sean Devine, Jimmy Marcus and Dave Boyle were friends. But then a strange car pulled up their street. One boy got in the car, two did not, and something terrible happened - something that ended their friendship and changed all three boys forever.
Twenty-five years later, Sean Devine is a homicide detective. Jimmy Marcus is an ex-con who owns a corner store. And Dave Boyle is trying to hold his marriage together and keep his demons at bay - demons that urge him to do horrific things.
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 facade.
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.
