I love the legend of Sherlock Holmes (I was born in London near his, perhaps fictional, offices. Truly!). Leah Scheier's novel, Secret Letters, brings the detective's world to life as she tries to solve a mystery in Victorian London. I have to say, I'm a sucker for this setting, and--superficially--I love the cover. Ah, London! There are a few ways to enter to win, below, so get to it.
