The Sherlockian, which takes as its jumping off point the famous hiatus in the Holmes saga when Sir Arthur Conan Doyle (above) killed off his burdensome creation at the Reichenbach Falls—and a collective wail of woe went up over the English-speaking world. The original story ("The Final Problem") can be found in the collection The Memoirs of Sherlock Holmes, which also recounts "The Musgrave Ritual" and other famed puzzlers. (Right: Holmes and Moriarty fighting over the Reichenbach Falls, by Sidney Paget.)
Apropos of Sherlock having a female partner in crime solving (i.e., Lucy Liu's stellar role as an upgraded Watson in Elementary), I quite enjoyed Laurie R. King's Justice Hall, in which Holmes's wife/partner, Mary Russell, exhibits a gratifying resourcefulness in danger-ridden undercover sleuthing.
Of the 40-some actors who have portrayed Sherlock, Benedict Cumberbatch, Jonny Lee Miller, and Robert Downney Jr are certainly arrestingly watchable with their tricked-out bells and whistles, but I do preserve a soft spot for the non-postmodern portrayals by Basil Rathbone and Jeremy Brett. How about you?
