Set against the backdrop of StreamPunk Victorian London in 1856, a plucky young American detective, 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 with everything to prove and prove she must as her first case is to catch a homicidal maniac of monstrous proportions, who is terrorising the innocent people of the East End.
