I am partial to historical mysteries especially when those tall tales count females in the leading role. You can imagine my bliss when I found this junior fiction series about a much younger sister to Mycroft and Sherlock Holmes setting about to solve her own puzzles. With the resurgence of interest in Sherlock Holmes via feature films and TV series (the BBC TV version is top notch) we are a market of readers primed and ready for a London mystery. Overall I highly enjoyed...
