One of France's best-selling writers at the time of the novel's composition, Dumas here combines what he considered to be life's essentials - `l'action et l'amour'. This historical romance is the climax of his epic of chivalry and valour that began with The Three Musketeers, and it is here that Athos, Porthos, Aramis, and their friend d'Artagnan, once invincible, meet their destinies.
