In 1966 the son of Bishop Pike committed suicide. After his death, Pike contacted the British medium Ena Twigg for a series of séances and she claimed to have communicated with his son. Although Twigg denied formerly knowing anything about Pike and his son, the magician John Booth discovered that Twigg had already known information about the Pike family before the séances. Twigg had belonged to the same denomination of Bishop Pike, he had preached at a cathedral in Kent and she had known information about him and his deceased son from newspapers.
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.
