The Beekeeper's Apprentice (Mary Russell, #1)
by Laurie R. King
Sherlock Holmes fanfic. Entertaining. I seem to remember a few bits toward the beginning that were too embarrassingly Mary Sue to read, but it settles down after a hundred or so pages. Interesting approach to story-telling: the speed of events changes wildly throughout the book---but very true to what it's supposed to be, which is a memoir.
