The mystery of the Man behind the Iron Mask has intrigued people for over 250 years, inspiring as much fantasy as serious conjecture. This is the story of the story, so to speak; an account of the theories and counter-theories, from the claim that he was the twin brother of Louis XIV to the recognition that he was Eustache Dauger, with diversion by way of such candidates as the Duke of Monmouth, Richard Cromwell, Molière, Nicholas Fouquet, an Armenian archbishop, an Italian astrologer and many more. Complete and comprehensive, this is a presentation of all the known facts of the prisoner's existence chronologically, as they have been discovered, together with all the myths as they have flourished from the preposterous stories put about by his gaoler in 1669 to the alleged discovery of his skeleton in a tower in Cannes in 1977. As the various stories are revealed, the reader may accept or reject the assorted evidence and develop his own views before the author presents his own conclusions. Illustrated.
