Lisa Hunter wakes in the grounds of Middleton Manor. Outside the gates, the wreck of her car smoulders, the charred bones of her husband attentive at the wheel.
After his funeral, Lisa has to decide whether to continue with her safe, under-achieving life or embrace her Middleton bloodline. However, there are gaps in her memory, pains in her head whenever she attempts to remember her experiences inside the Manor, but she feels there is a darkness inside the house, a black heart hidden within the walls.
When a local birdwatcher fails to return home from Whittingham Wood, the ensuing investigation takes Sergeant Ray Moreton to the neighbouring Middleton Estate, the scene of Lisa Hunters car crash and a place thought to be deserted. However, the ethereal playing of a violin from somewhere inside suggest its the birdwatcher or a member of the Middleton family has, once again, taken up residence.
