There is absolutely nothing to compare with the spine-chilling sensation of seeing a ghost. The shock and, all too often, the distress are better read about than experienced.Read about Princess Diana trying to exorcise a ghost which was troubling her father, or about Lord Rees-Mogg and the banshee haunting his family, or about the ghost of Elvis Presley that was chased by a clergyman from a council flat in Britain. Improbable, yes. But who knows? Real ghosts obey no natural laws. They emerge from the dark or the daylight - they are just there! Some hauntings have featured a single ghost, others several. Some had a handful of witnesses, others dozens. Some terrorised whole families, driving them out of their homes. Some ghosts were fleeting, others lingered for weeks. They all cause shock and wonderment.Britain's No. 1 collector of ghost stories presents a new anthology of persistent hauntings. Harry Ludlum, master story-teller, recounts his tales from all quarters of the ghost world.
