Athos, Porthos, Aramis, and D'Artagnan- the four musketeers- find themselves caught between conflicting loyalties. Deep inside the Bastille, a young prisoner called merely "Philippe" has languished for eight long years, completely unaware of his real name or the nature of his crime. But Aramis knows his secret- a secret so dangerous that it could change the face of the French monarchy and topple the King from his throne! Will Aramis' cause divide the once indivisible band of musketeers? A tale of mystery, adventure, and political intrigue, this conclusion to the musketeer saga is based on the true story of a masked prisoner who dwelled in the Bastille during Louis XIV' s reign.
