Non-canonical works of fiction featuring Sherlock Holmes, by creators other than Arthur Conan Doyle, have been referred to as examples of "Sherlockiana".[5] Charles Spencer, former theatre critic for The Daily Telegraph, used the term to refer to the 2009–12 releases of the novel The House of Silk, the television series Sherlock, and two Sherlock Holmes films, Sherlock Holmes and its sequel Sherlock Holmes: A Game of Shadows, as representative of a "golden age of Sherlockiana."[2]
