The British journalist Ruth Brandon published the book The Spiritualists (1983) which exposed the fraud of the Victorian mediums. The book received positive reviews and has been influential to skeptics of spiritualism. The British apport medium Paul McElhoney was exposed as a fraud during a séance in Osset, Yorkshire in 1983. The tape recorder that McElhoney took to his séances was investigated and a black tape was discovered bound around the battery compartment and inside carnation flowers were found as well as a key-ring torch and other objects.
The fraudulent medium Ronald Edwin confessed he had duped his séance sitters and revealed the fraudulent methods he had used in his book Clock Without Hands (1955). The psychical researcher Tony Cornell investigated the mediumship of Alec Harris in 1955. During the séance "spirit" materializations emerged from a cabinet and walked around the room. Cornell wrote that a stomach rumble, nicotine smelling breath and a pulse gave it away that all the spirit figures were in fact Harris and that he had dressed up as each one behind the cabinet.
In the late 1920s and early 1930s there were around one quarter of a million practising Spiritualists and some two thousand Spiritualist societies in the UK in addition to flourishing microcultures of platform mediumship and 'home circles'. Spiritualism continues to be practised, primarily through various denominational Spiritualist churches in the United States, Canada, Australia and the United Kingdom. In the United Kingdom, over 340 Spiritualist churches and centres open their doors to the public and free demonstrations of mediumship are regularly performed.
