The House Swap by Rebecca Fleet

'No one lives this way unless they want to hide something.'

When Caroline and Francis receive the offer of a house swap, they jump at the chance to heave a week away from home. After the difficulties of the past few years, they've worked hard to rebuild their marriage for their son's sake; now they want to reconnect as a couple.

On arrival, they find a house that is stark and sinister in its emptiness - it's hard to imagine what kind of person lives here. Then, gradually, Caroline begins to uncover some signs of life - signs of her life. The flowers in the bathroom and the music in the CD player might seem innocent to her husband, but to her they are anything but. It seems the person they have swapped house with is someone she used to know; someone she's desperate to leave in her past.

But that person is now in her home - and wants to make sure she'll never forget . . .
