I showed such interest in the Sherlock Holmes stories that by Christmas 1964 my parents bought me The Complete Sherlock Holmes, what we in "the game" call The Canon. I later found and enjoyed what I call the deuterocanonical stories in Arthur Conan Doyle's son's book, the Exploits of Sherlock Holmes.

My favorite non-canonical story would have to be "The Greatest Detective of All Time" by Ralph Roberts in which he time travels.
