The Vicomte de Bragelonne, the final installment of Alexandre Dumas's d'Artagnan Romances, follows the aging musketeers during the early reign of Louis XIV. The story centers on Raoul, Vicomte de Bragelonne and Athos's son, whose love for Louise de la Vallière is shattered when she becomes the king's mistress. Meanwhile, Aramis uncovers the secret of the Man in the Iron Mask—Philippe, the king's twin brother—and plots to replace Louis on the throne. As the conspiracy collapses, Porthos dies heroically, Athos passes away in grief, and d'Artagnan falls at the siege of Maastricht, ending the musketeers' era in tragedy.
