"The Man in the Iron Mask" by Alexandre Dumas is a novel published between 1847 and 1850. This thrilling conclusion to the d'Artagnan Romances follows the aging musketeers during Louis XIV's early reign in 1660s France. As d'Artagnan becomes Captain of the King's Musketeers, political intrigue swirls around the ambitious Nicolas Fouquet. Meanwhile, Aramis discovers a mysterious prisoner in the Bastille who bears an uncanny resemblance to the king himself—a secret that could reshape the fate of France and test the musketeers' loyalty forever.
