I know who did it / Steve Mosby.

The hardest crimes to acknowledge are your own. Charlie Matheson died two years ago in a car accident. So how is a woman bearing a startling resemblance to her claiming to be back from the dead? Detective Mark Nelson is called in to investigate and hear her terrifying account of what she's been through in the afterlife. Every year Detective David Groves receives a birthday card for his son...even though he buried him years ago. His son's murder took everything from him, apart from his belief in the law, even though the killers were never found. This year, though, the card bears a different message: I know who did it. Uncovering the facts will lead them all on a dark journey, where they must face their own wrongs as well as those done to those they love. It will take them to a place where justice is a game, and punishments are severe. Nelson and Groves know the answers lie with the kind of people you want to turn and run from. But if they're to get to the truth, first they'll have to go through hell...
