In Paranormal: The Girl, The Ghost and The Gravestone, Radio 1 presenter Sian Eleri investigates a seemingly ordinary farmhouse in north Wales which, in the late 1990s, was widely considered the most haunted house in Britain.The story made local and national headlines as the family who lived at the farm became ever more desperate in their search for answers. More than 300 apparently paranormal events were documented at the house in video footage, audio interviews, photos, and eye-witness accounts – all of which had been locked away, until now.
