Natural History of Ghosts

What explains ghost sightings? What do haunted people see? And what proof is there? Roger Clarke, who spent his childhood in two haunted houses, has produced the first comprehensive study of the evolution of the ghost, through the stories of the hauntings that have most obsessed the world. From religious beliefs to modern neuro-science, from haunted houses to haunted submarines, and from hoaxers to true believers, he covers the many manifestations of our fascination with ghosts and fear of the dark.
