Last autumn I was reading a book about the Enfield 'poltergeist' in 1977 for the script I was writing. Decided to get it from the library again. So I'm reading This House is Haunted by Guy Lyon Playfair, one of the investigators involved.
I'm always skeptical about things like this, but at the same time, I love a good ghost story. And I think the ones that are more successful are things like this, with the reality edge. It's like the stories you'd tell as kids, the ones that were really scary were the ones that happened to 'a friend of a friend'...happening to people only two steps away from you. Too close to home!
