In nine short stories, seven of which have never previously been available in print, and one brand new, never-before-seen Sherlock Holmes mystery - available together for the first time - Laurie R. King blends her long-running brand of crime fiction with historical treats and narrative sleight of hand. At the heart of the collection is a prequel novella that begins with England's declaration of war in 1914. As told in Mary Russell's teenage diaries, the whip-smart girl investigates familial mysteries, tracks German spies through San Francisco, and generally delights with her extraordinary mind - until an unimaginable tragedy strikes.
