Will Ransley, the illegitimate nephew of the Earl of Swinford, is endowed with the appearance of a true aristocrat and the ingenuity of a street child who grew up in the London slums. In an effort to help his cousin restore his good name, Will goes to Vienna. His goal is to find Elodie Lefebvre, the woman who lured Max into a trap and thereby ruined his diplomatic career. An adventurer by nature, he decides to rescue a seductive Frenchwoman from the supervision of the authorities, deliver her to the British Foreign Office and force her to testify. During a journey full of dangers and adventures, Will will have to decide who the beautiful Elodie really is: a treacherous spy or a lady in trouble?
