Three days after Christmas, a woman walks into a police station. She has no phone and no ID, just a piece of paper with the name of investigator David Raker on it. She tells officers that Raker is her husband. SHE SAYS SHE'S MY WIFE. When he turns up at the station, Raker is stunned. The woman looks exactly like his wife. She knows all about their marriage, their history, even private conversations the two of them had. There's just one problem: Raker's wife has been dead for eight years. MY WIFE DIED . . . DIDN'T SHE? The woman tells the police that Raker had a breakdown. A respected doctor backs up her account. Items are missing that prove Raker's side of the story - and, worst of all, he soon becomes the prime suspect in a disappearance. SHE'S EITHER A LIAR - OR I AM. Could Raker have imagined their whole marriage? Is he delusional? Is this really the woman he loved and grieved for? Hunted by the police, Raker will have to find out the truth before it costs him everything - his memories, his sanity, his life . . .
