Steed impersonates the forger Riordan, which allows him to join a crime syndicate that prints forged banknotes. Having uncovered their plans, he finds his every move being watched by The Cardinal - the second-in-command. Only the pretence of an injury eventually allows Steed to visit his Doctor's surgery and Keel ensures that The Cardinal and his superiors, Bloom and Hooper are arrested.
