Maurice Grosse , aged 76, is a psychic investigator. In 1977 he led the team that hunted the Enfield poltergeist, a widely publicised event which he says inspired the hit Hollywood movies Ghostbusters and Poltergeist.
Investigating claims by people who believe they have witnessed manifestations of the supernatural, Maurice Grosse 's video diary includes footage of an all-night vigil at Charlton House, a building in London believed to be haunted.
