Kingsley Doyle died from pneumonia on 28 October 1918, which he contracted during his convalescence after being seriously wounded during the 1916 Battle of the Somme. Brigadier-General Innes Doyle died in February 1919, also from pneumonia. Sir Arthur became involved with Spiritualism to the extent that he wrote a Professor Challenger novel on the subject, The Land of Mist. His book, The Coming of the Fairies (1921) shows he was apparently convinced of the veracity of the Cottingley Fairies photographs, which he reproduced in the book, together with theories about the nature and existence of fairies and spirits. In his The History of Spiritualism (1926) Conan Doyle praised the psychic phenomena and spirit materialisations produced by Eusapia Palladino and Mina "Margery" Crandon. His work on this topic was one of the reasons that one of his short story collections, The Adventures of Sherlock Holmes, was banned in the Soviet Union in 1929 for supposed occultism
