The ghosts of Hollywood, the death of Edgar Allan Poe, the loving Martian, the Zone of Silence, bewitched diamonds...Joslan F. Keller tells us 18 disturbing stories that defy reason. Eighteen paranormal areas around the world, all authenticand documented by the author, which shake our certainties: unexplained phenomena in the sky, incursions into the worldof spirits, encounters with unusual characters, close contacts with UFOs, visits to disturbing places...Doesn't the improbable arise from our still limited knowledge and our inability to rationally explain phenomena that are beyond our understanding? The world is neither black nor white. Are there not an infinite number of grey areas, at the frontiers of the unknown, dominated by forces whose mechanisms are little or not explored?
