born very poor in the most unfortunate london, william seeks a social redemption in the cavalry and the way to conquer the fascinating and haughty jocelyn, which the rules of caste have already given to count adhemar. from obscure grooms, william, thanks to his innate talents, becomes a great champion of chivalric tournaments and, to give more luster to his credentials, he adopts a stage name and invents a past that makes him pass for an aristocrat.
