I buried you. I mourned you. But now you're back. The addictive new thriller from the Sunday Times bestseller. She says she's my wife. Either she's a liar - or I am.

A woman walks into a police station. She has no ID, just a piece of paper with the name 'David Raker' on it. She says she's his wife.

The woman looks just like her. She knows everything about him and their life together. But David buried his wife eight years ago.

A day later, she vanishes.

Now the prime suspect in her disappearance, David must find out the truth before the police close in. But what is the truth? If this is really his wife, is he losing his mind? And if it isn't, who is she and what sinister game is she playing?
