I just stumbled across this:
We Faked The Ghosts of Borley Rectory
An autobiography exposing the world of psychical research. Born at an unusually early age for a child, the author became entangled in a world of faked haunting, phoney poltergeist activity and the creation of ghostly apparitions when staying at the infamous Borley Rectory in Essex. "The most haunted house in England and the best-documented case of haunting in the annals of psychical research". Here, for the first time, this universally unknown story is exposed - and the true facts revealed. "... probably the most bizarre parapsychical exposure ever written ... an intriguing biography of intense enchantment." Maeterlinck Press Agency

Surprisingly, the Amazon page features a slew of reviews saying the book';s hard to follow.
