When this book was first published in 1903 Leonora Piper was regarded as the most tested trance medium to date. A quote from the S.P.R. (Society for Psychical Research) stated: “Mrs Piper’s mediumship is one of the most perfect which has ever been discovered.” Over a period of 15 years’ members of the Society had hundreds of sittings with her, communicating with numerous personalities. This book focuses upon the evidence and is an in-depth examination of where this information could have been obtained from. Was it telepathy, mind reading, secondary personalities or does it support the Spiritualist belief in life after death?
