As we've seen with Laurie King's Mary Russell series, and many other Sherlock Holmes pastiches of various kinds, Sherlock Holmes is certainly still alive and well in the world of literature. One of the more recent book reviews I've read demonstrates how intriguing the genre of Sherlock Holmes based fiction can be: Who Thinks Evil by Michael Kurland is one of a series of "Moriarty mysteries" by the author. Apparently, while Holmes is out of the country, and Moriarty is awaiting a verdict which could implicate him in a crime, Mycroft Holmes utilizes him to help solve a crime, sort of like Hannibal Lecter does in The Silence of the Lambs, I imagine.
The review linked below, from newsok.com, gives a pretty concise synopsis of the novel, and it actually strikes me as one that could be well worth my attention:
Book Review: Who Thinks Evil by Michael Kurland
Incidentally, a quick search of Michael Kurland on our local library website shows that the author has also edited a few collections of Holmesian "apocrypha": Sherlock Holmes; The American Years, My Sherlock Holmes: Untold Stories of the Great Detective, and Sherlock Holmes: The Hidden Years.
