Scream of Fear (1961)

In my opinion one of the better Hammer horror movies. A young woman confined to a wheelchair pays a visit to her father for the first time in 10 years; only he's not there and her stepmother and his chauffeur are very suspicious about his whereabouts, and the daughter keeps seeing her father's (Christopher Lee, who although he didn't do any 'acting' in this movie, and I really can't figure out why they got him for such a meager role except that he definitely looked scary) corpse around the property, but nobody else does.

LOVE this movie, has anybody else seen it?
