pulse. Price was suspicious that the supposed spirit of the child was no different than a human being but after the séance had finished the starch powder was undisturbed and none of the seals had been removed on the window. Price was convinced no one had entered the room via door or window during the séance. Price's Fifty Years of Psychical Research (1939) describes his experiences at the sitting and includes a diagram of the séance room. Eric Dingwall and Trevor Hall wrote the Rosalie séance was fictitious and Price had lied about the whole affair but had based some of the details on the description of the house from a sitting he attended at a much earlier time in Brockley, South London where he used to live. K. M. Goldney who had criticised Price over his investigation into Borley Rectory wrote after the morning of the Rosalie sitting she found Price "shaken to the core by his experience." Goldney believed Price had told the truth about the séance and informed the Two Worlds spiritualist weekly newspaper that she believed the Rosalie sitting to be genuine. In 1985, Peter Underwood published a photograph of part of an anonymous letter that was sent to the SPR member David Cohen in the 1960s which claimed to be from a séance sitter who attended the séance. The letter confessed to having impersonated the Rosalie child in the sitting by the request of the father who had owed the mother of the child money. In 2017, Paul Adams published details of the location of the Rosalie seance and identities of the family involved. Reception Psychologist and sceptic Richard Wiseman has praised Price for his work in debunking fraudulent mediums and investigating paranormal claims. According to Wiseman "Price devoted the scientific study to weird stuff ... that both delighted the world's media and infuriated believers and sceptics alike." The stage magician and scientific sceptic James Randi wrote Price accomplished some valuable and genuine research but lived "a strange mixture of fact and fraud." Psychical researcher Renée Haynes described Price as "one of the most fascinating and storm-provoking figures in psychical research." Science writer Mary Roach in her book Spook: Science Tackles the Afterlife (2010) favourably mentioned Price's methods and research in debunking the fraudulent medium Helen Duncan. Several biographies have been written about Price. Paul Tabori's biography (1974) is generally sympathetic. Historian Trevor H. Hall's
