The mark of Cain

In 1567, young Aphra is found in the marsh by two witches. They recognize her abilities in the dark arts immediately, but they are burned as witches before Aphra grows very old. Aphra finds companionship with the leper Long Lankin, but comes down with leprosy herself before being burned herself. Before she dies she casts a curse on her tormentors, and now, in 1962, sisters Cora and Mimi, last of that family line, find themselves trapped in an ancient house with a spirit bent on revenge.
