A woman wakes up and opens her eyes - she knows immediately that she's not in the bed she went to sleep in. It's just the beginning of her nightmare. Across town, a child discovers a woman's body buried beneath the beach. Then another victim is found. Yet neither friends nor family had even reported either woman missing. How could their killer be getting away with murder? For Detective Inspector Helen Grace, it's chilling evidence that she's searching for a monster who's not just twisted, but also clever and careful. And as Helen struggles to understand the motivation behind the crimes, she begins to realise that time might be running out for someone still alive.
