Crowhaven Farm (1970)

An aura of mystery and tales of supernatural activity surrounds Crowhaven Farm, when it comes into the possession of Ben and Maggie Porter, a couple moving to the farm to try for a chance to save their troubled marriage. Maggie immediately senses that all is not right, and that perhaps the farm's reputation for being haunted by restless spirits and being the home of an ancient coven of witches is true. —free_to_finn
