In 1931 at the Irvings' farmhouse on the Isle of Man there were poltergeist bangs, words and, then, the appearance of Gef a talking weasel-like creature with human hands, 'the extra, extra clever mongoose'. Join Simon and Chris as they attempt to be extra, extra clever about Gef who could talk, sing, report gossip from all over the island and do selfies. Expect to learn what kind of families produce poltergeists, why Harry Price was a 'conman', and whether Gef's pronouncements are teenage or frustrated adult male. And what was Gef really? A poltergeist? Folie en famille? An actual talking animal? Tulpa? A witch's familiar? Or a hoax by one or all of the Irvings, so disappointed in their lives?
