There are few factual books written about poltergeist phenomena, Johns Frasers Poltergeist! A New Investigation Into Destructive Haunting fills that void, advancing and updating Colin Wilsons work Poltergeist!, this studys namesake from over 38 years ago. Fraser takes readers on a journey from the Borley Rectory to the Isle of Man, and grounds his readers in an historical overview of Poltergeist phenomena. He examines where such events overlap with other paranormal investigations of apparitional ghosts. What do they have in common, what do they differ? To answer this, Fraser looks to new research on paranormal events, never before published in book form. Fraser contends, perhaps controversially, that ghost sightings are and always will be ambiguous and near-impossible to prove, that only Poltergeist phenomena can be empirically verified.
