Set against the backdrop of steampunk Victorian London in 1856, a plucky young American detective named Cordelia Swift is the newest addition to Scotland Yard, much to the disgust of her peers and colleagues, for both being foreign and a woman. Cordelia is a smart (but naïve) detective who’s out to prove she has what it takes on her first case: a homicidal maniac of monstrous proportions who is terrorizing the innocent people of the East End.
