Isaac Asimov was a Sherlockian and a member of the Baker Street Irregulars. He edited a book of Holmes/Sci-Fi crossover short stories called “Sherlock Holmes Through Time and Space,” containing stories from many different authors and also one of his own. The story he contributed to this edition actually was about Professor Moriarty and his Doctoral Thesis (“The Dynamics of an Asteroid”) and served as the essay he had to submit in order to become a member of the BSI. After being inducted as a member, his BSI title became The Worm Unknown to Science.
Asimov also founded his own mystery club originally called The Trap Door Spiders. The name later was changed to The Black Widowers and he wrote three books of short stories: “Tales of The Black Widowers,” “More Tales of the Black Widowers” and “The Casebook of the Black Widowers.”
One of his short stories in the second volume, “Nothing Like Murder,” was a tribute to J. R. R. Tolkien. All of this makes Asimov awesome and how can you not love a man with muttonchops like that.
If you enjoy sf/fantasy and Holmes overlap take a look at a newer short story anthology, ”Improbable Cases of Sherlock Holmes.” It includes writers like Laurie King, Stephen King and Neil Gaiman as well as a large amount of Lovecraftian mythos.
