Hannah Riley and her musician husband, Will, hope that a move to the Suffolk countryside will promise a fresh start.
Hannah, a human rights worker, is desperate for a child and she hopes that this new life will realise her dream.
Yet when the snow comes, Will is working in London and Hannah is cut off in their remote village. Life in Tornley turns out to be far from idyllic, who are the threatening figures who lurk near their property at night? And why is her neighbour so keen to see them leave? Plus Will's behaviour is severely testing the bonds of trust.
Hannah has spent her professional life doing the right thing for other people. But as she starts to unbury a terrible crime, she realises she can no longer do that without putting everything she's ever wanted at risk.
But if she does nothing, the next victim could be her . . .
