A young woman wakes up in a cold, dark cellar, with no idea how she got there or who her kidnapper is. So begins her terrible nightmare . . .

Nearby, the body of another young woman is discovered buried on a remote beach.

But the dead girl was never reported missing - her estranged family having received regular texts from her over the years.

Someone has been keeping her alive from beyond the grave.

For DI Helen Grace, it's chilling evidence that she's searching for a monster not only twisted and clever - but a predator who's killed before.

Now, as she struggles to understand the killer's motivation, she begins a desperate race against time . . .
