Thrown objects, apparent levitation, and a dead man who seems to speak through a 12-year-old girl. It can only be The Enfield Poltergeist. It's a story that made national headlines in 1977, and has caused controversy ever since. Was the phenomena genuinely paranomal, or did a 12-year-old girl somehow pull off a hoax that fooled dozens of eyewitnesses - from journalists to the police.
Danny Robins and the team look at the evidence, and talk to Graham Morris, whose iconic photographs documented activity inside the house, in a special episode recorded live at the Crossed Wires Festival in Sheffield.
