Sherlock Holmes's arch-enemy is thought to have been Professor James Moriarty (whose brother, a station master, was also named James Moriarty). There is something odd about the chronology of the two stories in which he figures, "The Final Problem" and “The Valley of Fear.” And he seems to have been involved in only two of the sixty published cases—although there is a popular impression (based perhaps on films and parodies) that Holmes and Moriarty dueled throughout their long careers.
The drawing above is by Sidney Paget, an illustration for the original publication of "The Final Problem" in 1893. Note the spelling: James Moriarty. Not Moriarity, not Moriaty, not Morrity, not even, as one parodist rendered it, Arty Morty!
