Roberts met Gurdjieff in Tiflis in 1919. His book In Denikin's Russia and the Caucasus, 1919-1920 (1921) contained the first description of Gurdjieff published in English.[5] His 1928 novel This Side Idolatry (by the pseudonym "Ephesian") was the first public presentation of the relationship between Charles Dickens and the actress Ellen Ternan.[6]
Roberts died in a motor accident in December 1949.[4]
Psychical research
Roberts took interest in psychical research and spiritualism, but approached these subjects from a mostly skeptical position.
He was the author of The Mysterious Madame: A Life of Madame Blavatsky (1931), a highly critical biography of Helena Blavatsky. In his book The Truth about Spiritualism (1932) he came to the conclusion that there is no evidence for the spirit hypothesis in mediumship. According to the research of Roberts all séance and spiritualist phenomena can be explained by "telepathy, self-deception, fraud or neurosis".[9]
Roberts was convinced that the medium Helen Duncan was a fraud and wrote a foreword to the book The Trial of Mrs. Duncan (1945) by Helena Normanton.[10]
