Niall and Eden Paternoster start their Sunday the same way they always do, with a long drive, a visit to a country house and a quick stop at the local supermarket on the way home. But this Sunday ends differently because while Niall waits and waits in the car park for Eden to pick up supplies, Eden never returns. She's not waiting for him at home, and none of their family or friends have heard from her. Gone without a trace, Niall is arrested on suspicion of her murder. When DS Roy Grace is called in to investigate, it doesn't take long to realize that nothing in this case is quite as it seems.
