“Apparitions and thought-transference: an examination of the evidence for telepathy” by Frank Podmore
Frank Podmore was a skeptic member of the Society Of Psychical Research. Previously a believer in spiritualism, his opinion changed when some of the mediums he believed in were revealed as frauds. In this book, Podmore gives examples of actual case studies of ghosts and telepathy, and his view point on if it could be real, or fraud.
