spooky tv prog

[shadowchaser]

I've had this memory of a spooky tv programme from the late seventies/early eighties (?) that starred Ian Ogilvy and was in a boarding school or similar establishment and saw Ogilvy donning black leather gloves and pushing a kid into a cupboard/or killing him...can't remember which...would love to know what it was - can't find any reference to it on imdb or ian ogilvy's website...i'm pretty sure it was him, though!

Can anyone help?
