So I've been reading through all the research on Borley and the more I dig, the more it looks like Harry Price basically invented most of the phenomena. The poltergeist activity conveniently ramped up when he was investigating, witnesses' accounts don't match his notes, and there's evidence he literally staged things.
It's the most famous "haunted house" in British paranormal history and I reckon we've all been had. The building's gone now anyway so can't exactly verify anything.
Am I being unfair? Did Borley actually have something genuine that Price exploited, or was the whole thing theatre?
