booby trap

Can any one help on this one?, it was early to mid 60's, one of those BBC tea time Sunday serial dramas. All i can remember was that in the titles, there was a large white clown's mask, you know the type that fitted over the whole head just like the one's they wear in carnivals.(come to think of it i think it revolved as the tiles ran). I think the series was called Mask of the Clown or Face of the Clown, any way i can remember it being eerie as a child.
I think the clown was some sort of criminal.
