Paranormal Activity producers get Jealous

The Paranormal Activity producers are already moving onto their next project, an adaptation of Celia Fremlin's 1985 book The Jealous One. The Jealous One is about a woman who dreams she murdered another woman who was tempting her husband. She awakens to find that the woman she dreamed of is missing. The book is described as Hitchcockian. Sounds intriguing.
