Written by an experienced and extensively published investigator of psychic phenomena, this is a well documented account of the appearance of phantoms as apparitions of both the living and dead, poltergeists, animal materializations, hauntings and out-of-the-body experiences.

Rogo's style is pleasant to read. I have been lucky enough to once find, by hazard, an old Italian translation of the book. Very interesting reading, because most cases included are nowadays classics and rarely mentioned. Front cover design shows some creativity. A must have.
