Review by jamesdrew

A remarkably creepy and subtle evocation of dread, from a typically nuanced Nigel Kneale script. What if ghosts are simply phenomena that have simply been poorly described? That's just what a team of computer specialists, on the trail of a new recording medium, attempt to do when they discover that the old mansion in which they are conducting their work is haunted by the ghost of a victorian maid. Unfortunately, they discover too late that a rational explanation does not mean an end to the terror... TV drama as it should be done – sadly, we'll probably never see its ilk on British TV again. Still, at least those nice chaps at BFI have released it on DVD.
