When your life is a lie, who can you trust? When Maggie Taylor accepts a new job in Manchester, she is sure it is the right move for her family. The children have settled well, although her husband, Duncan, doesn't appear to be so convinced. But nothing prepares her for the shock of coming home from work one night to find that Duncan has disappeared, leaving their young children alone. His phone is dead, and she has no idea where he has gone or why. And then she discovers she's not the only one looking for him. When a woman who looks just like Maggie is brutally murdered and DCI Tom Douglas is brought in to investigate, Maggie realises how little she knows about Duncan's past. Is he the man she loves? Who is he running from? She doesn't have long to decide whether to trust him or betray him. Because one thing has been made clear to Maggie – another woman will die soon, and it might be her.
