Every cop needs a good partner… In this line of work, you have to trust the person who's watching your back. When Claudia Parrish's partner–and lover–dies, she figures "happily ever after" just isn't going to happen. A year later, she's assigned another partner and before long, begins to wonder if she might have a chance, after all. Gavin Monaghan is the new guy in the Homicide Unit. He's a good detective with plenty of experience. Except he's not really who he says he is. He's an undercover Internal Affairs agent assigned to find the cop responsible for the evidence tampering that's allowing criminals to walk. Gavin knows he has to do whatever it takes to find the one bad cop. But that might just mean gaining Claudia's trust only to betray her.
