When the village of Priors Bramley was shut off in the 1950s so that the area could be used for chemical weapons-testing during the Cold War, a long history of dark secrets was also closed off to the outside world. Now, sixty years later, the village has been declared safe again, but there are those living in nearby Bramley who would much rather that the past remain hidden.
When the village is reopened, Ella Haywood, who used to play there as a child, is haunted by the discovery of two bodies. Shortly before the isolation of the village, she and her two oldest friends had a violent and terrifying encounter with a stranger - with terrible consequences. They made a pact of silence at the time, but the past has a habit of forcing the truth to the surface.
With the mystery surrounding the now derelict Cadence Manor drawing increasing local interest, Ella finds that she will have to resort to ever more drastic measures if she is to make sure that no one discovers what really happened all those years ago.
