Curse of the Crimson Altar (1968)
When his brother disappears, Robert Manning pays a visit to the remote country house he was last heard from. While his host is outwardly welcoming - and his niece more demonstrably so - Manning detects a feeling of menace in the air with the legend of Lavinia Morley, Black Witch of Greymarsh, hanging over everything. witch, virgin, sacrifice, police, england, cemetery, niece, old dark house, witchcraft
