A Shambles in Belgravia

A Shambles in Belgravia by Kim Newman (who wrote the highly entertaining alternate history / vampire literature mash-up Anno Dracula series), is part of the BBC’s Sherlock Holmes website. Newman’s story isn’t about Holmes, though; it’s about his dark reflection, Professor Moriarty.
The story is subtitled Being a reprint from the Reminiscences of Col. Sebastian Moran, Late of the 1st Bengalore Pioneers, and describes Mortiarty’s encounter with Irene Adler (the one woman Holmes is said to have admired). It starts: To Professor Moriarty, she is always that bitch.
