All Hallows Hall is a rambling Tudor mansion on the edge of the bleak and misty Dartmoor. It is not a place many would choose to live. Yet the former Governer of Dartmoor Prison did just that. Now he's dead, and his children - long estranged - are set to inherit his estate.
But when the dead man's family come to stay, the atmosphere of the moors seems to drift into every room. Floorboards creak, secret passageways echo, and wind whistles in the house's famous priest hole. And then, on the same morning the family decide to leave All Hallows Hall and never come back, their young son Timmy disappears - from inside the house.
Does evil linger in the walls? Or is evil only ever found inside the minds of men?
