Growing Rich

Does anybody remember this from the late 80's? Written by Fay Weldon and staring Martin Kemp...?

It was an itv production about the Devil messing with 3 upper-school girls.

Ambition, boredom, poverty, envy, lust, Clairvoyant/schizophrenic mothers...all very Weldon, all very dark and memorable.

I was lucky to find a VHS copy in a charity shop for 10p a few years ago. No DVD as far as I know.
