The blistering new thriller from the two million copy Sunday Times bestselling author.

They thought they'd found their dream house. They were wrong . . .

Adam and Jess move into a new house with their three young children: a rambling Victorian villa right at the very top of their price range. Before long Adam discovers a door hidden behind a fitted wardrobe, concealing a secret room . . .

Inside Adam discovers an array of forgotten items, among them a wallet, an antique watch and an old mobile phone. Jess thinks they should simply throw them away. But Adam resists. He is fascinated by these items and how they came to be inside the hidden room.

But like the house, Adam has his secrets too. And soon he will find himself setting in motion a series of events that will place his family in terrible danger . . .
