Alternate England, 1851. Lessons in the art of espionage aboard Mademoiselle Geraldine's floating dirigible have become tedious. Sophronia would much rather be using her skills to thwart the dastardly Picklemen, yet her concerns about their wicked intentions are ignored, and now she's not sure whom to trust. What does the brusque werewolf dewan know? On whose side is the ever-stylish vampire Lord Akeldama? A large-scale plot is under way, and when it comes to fruition, Sophronia must be ready to save her friends, her school, and all of London from disaster-- in decidedly dramatic fashion, of course. In an alternate England of 1851, Sophronia Temminnick is the only hope for her friends, her school, and all of London when she must put her espionage training to the test to thwart an evil Picklemen plot.
