After her death in the 1980s the medium Doris Stokes was accused of fraud, by author and investigator Ian Wilson. Wilson stated that Mrs Stokes planted specific people in her audience and did prior research into her sitters. Rita Goold a physical medium during the 1980s was accused of fraud, by the psychical researcher Tony Cornell. He claimed she would dress up as the spirits in her séances and would play music during them which provided cover for her to change clothes.
"The picture reading shows me what goes on in the past life and in this life ... So if it shows me she was your guardian angel at one point, she was a guardian angel," she said. She added that the reading wasn't accurate because I had come in with the intention to trick, that the energy I came in with was one about my sister which is what she picked up on, that the whole thing wasn't very "civilized" of me and that she'd be calling other psychics and warning them about me. She told me she's been tested by people who declared their intentions and passed their tests, and offered to give me a reading that would reveal secrets about me that not even my closest friends know. I declined.
In September 1878 the British medium Charles Williams and his fellow-medium at the time, A. Rita, were detected in trickery at Amsterdam. During the séance a materialized spirit was seized and found to be Rita and a bottle of phosphorus oil, muslin and a false beard were found amongst the two mediums. In 1882 C. E. Wood was exposed in a séance in Peterborough. Her Indian spirit control "Pocka" was found to be the medium on her knees, covered in muslin.
