What secrets is she keeping in the hidden room...?

Life is good for Laurie and Martha. They have a beautiful home in the fens, three great kids. Laurie's career as an architect has suddenly taken off.

But when a stranger arrives in town, things begin to go wrong. Martha feels resentful of Laurie's success. Teenage daughter Hope becomes withdrawn and obsessive. And Laurie can do nothing. Because this isn't a stranger. She knows this man all too well - and what he's capable of. He's come back for her. And if she tells anyone the truth - she will lose everything.
