Roy Stemman, former editor of Psychic News, is author of Spirits and Spirit Worlds, Reincarnation: True Stories of Past Lives, Spirit Communication, One Soul Many Lives, Mysteries of the Universe, Healers and Healing, Medium Rare: The Psychic Life of Ena Twigg, and (with George Chapman) Surgeon From Another World.

Here he discusses the healing mediumship of George Chapman (1921 - 2006) under the spirit control of Dr William Lang (1851 - 1937) that lasted for six decades. The authenticity of Dr Lang's spirit was attested to by family members, former patients, and medical colleagues. Many miraculous cures were reported and endorsed by medical personnel. The case has attracted international attention – and is among the most evidential examples of human postmortem survival.
