The current owners of the family estate, Lord and Lady Rillington (Geoffrey Beevers and Suzanne Neve), have fallen on hard times and are facing the possibility of having to sell the house to private developer Wilkinson (Terrence Rigby).

Highlights include an episode where a school-boy who is set to doing some lines in a hall at his school when it becomes apparent that he is not alone. Although I'm more than old enough to remember this series, I never saw it first time round so my review is not clouded by nostalgia. And everything is rotting – expect the chair by the fireplace, the chair sally tries to sit in but it doesn’t feel right.The man was brought back to the castle where he was held for six months, being questioned or tortured.

After dressing as a frankly alarming bat at the world’s worst fancy-dress party (where everyone else, for licensing reasons, is clad not as a character from films or books but as unidentifiable horrors from a Ray Bradbury nightmare), she decides to exorcise the demon ‘Amelia’ from inside Amy – only to promptly be revealed (to no one’s surprise) as the baddie after all.The unsettling camera work certainly helps but the narrative weaving of innocent pastimes like playing scrabble into something far more sinister is highly effective. During the info dump Peter mentions his grandmother being scared of this place and Sally notices that none of the window panes are broken. The series tended to feature single dramas with a science fiction, supernatural and occasionally satirical theme.
