She brought about her own death by accident, then, wandering the earth as a restless spirit, she attacked and conquered the body of the lovely Peri Lee. After a desperate battle, she drove the young girl’s soul down into the depths of her psyche. Then she led the life of a lovely wanton, but, more and more she came to realize that she had committed a terrible crime.
