In November 1920, the celebrated author Sir Arthur Conan Doyle announced the beginning of a new “epoch in human thought.” He believed that he was presenting “a strong prima-facie case” for the existence of fairies, based on photographs taken by two pseudonymous young girls in July and September 1917. Noting that “in a matter involving so tremendous a new departure one needs overpowering evidence before one can say that there is no conceivable loophole for error,” he laid out the case for the existence of fairies in the village of Cottingley, Yorkshire. Some have seen this announcement in The Strand Magazine and Doyle’s subsequent book, The Coming of the Fairies, as the writings of a sixty-one year old who was losing his ability to think rationally. But to truly understand why the creator of Sherlock Holmes, one of the most unsentimental and logical characters in literature, would believe in fairies requires an understanding of Doyle’s life, his general acceptance of Spiritualism, and what he felt would be the result of widespread recognition of the Cottingley photos.
The above is a good chunk of the first paragraph of an introduction that I wrote for a new edition of Doyle’s The Coming of the Fairies (University of Nebraska Press, 2006) that is now available on Amazon. While it is clear – despite the protestations of some supporters even to this day – that the photographs were indeed faked by the young protagonists, the introduction aims to provide the reader with sufficient background to appreciate Doyle’s claims and, while not to support the existence of fairies, to understand why Doyle wanted them to exist.
