High above a steampunk London of Penny Dreadfuls, Jack the Ripper and pea-soup fog... stals the legendary demon, Springheeled Jack! From his quarters in Bedlam lunatic asylum, Sir Jack Rackham hunts the creature that took his beloved. But just who or what is Springheeled Jack? Does the answer lie amongst the lunatics of Rackham's sanatorium - or in the very heart of the British Empire: with Queen Victoria at Buckingham Palace?
