Query: Terrific drama - about time we had a DVD release!

Probably one of the best mini series on the BBC in 1989. This is a taut, psychological thriller staring David McCallum and Diana Rigg. It's too bad it was never released on DVD but perhaps now is the time!! Adapted from Domini Taylor's novel (same name) this is a neat, scary story done by some great actors. Can't recommend it enough...
