A 1994 article in The Salt Lake Tribune reports that Sherlock Holmes creator Sir Arthur Conan Doyle characterized his depictions of Mormonism thusly: "[I]t is likely that in a work of fiction it is stated more luridly than in a work of history." Now, following an objection from a local parent, the Albemarle County School Board has removed Doyle’s first Holmes novel, A Study in Scarlet, from sixth grade reading lists for its depiction of the Mormon faith.

"You know Father would be the first to admit that his first Sherlock Holmes novel was full of errors about the Mormons," said Dame Jean Conan Doyle, Arthur’s daughter, in 1991.
On a semi-related note, the American Library Association keeps a list of banned or frequently challenged books here. Also of interest: The Adventures of Sherlock Holmes was banned in the Soviet Union in 1929.
