John Hough directs Peter Cushing, Mary Collinson and Madeleine Collinson in this Hammer Horror about a religious zealot who is burning young “witches” only to discover his twin nieces might be harbouring an even nastier malignancy. 

Bog standard period horror product. To modern eyes it is about as scary as a My Little Pony catalogue. Interesting only in that pretty much every character is corrupted by their extremism, there’s no obvious hero, certainly not Cushing. And the Playboy Playmates Collinson twins are very easy on the eye, a fact not lost on the costume designers nor the cinematographer, who eagerly dress them up and down like dolls in a risqué playset as often as they possibly can.
