The Vicomte of Bragelonne: Ten Years Later (French: Le Vicomte de Bragelonne ou Dix ans plus tard [l@ vikot d@ bRaZ@lon u diz_a ply taR]) is a novel by Alexandre Dumas.
This part mostly concerns romantic events at the court of Louis XIV. Raoul de Bragelonne finds his childhood sweetheart, Louise de La Valliere, is maid of honour to the Princess. Fearing a tarnishing of Louise's reputation by affairs at court, Raoul seeks to marry her. His father, Athos, the Comte de la Fere, disapproves, but eventually, out of love for his son, reluctantly agrees. The king, however, refuses to sanction the marriage because Louise is of inferior social status, and so marriage is delayed.  Meanwhile, the struggle for power begins between Fouquet and Colbert. Louis attempts to impoverish Fouquet by asking for money to pay for a grand fete at Fontainebleau. Meanwhile, Aramis meets the governor of the Bastille M. de Baisemeaux, and learns of a secret prisoner who bears a striking resemblance to Louis XIV. Aramis uses this secret to persuade the dying general of the Jesuits to name him his successor.  After Buckingham leaves France, the Comte de Guiche grows besotted with Henrietta, as soon does Louis XIV. To avoid her new husband being jealous Henrietta suggests that the king choose a young lady at court to act as a smokescreen for their flirtation. They select Louise de la Valliere for this part, but during the fete, the king overhears Louise confess her attraction for him to friends, and promptly forgets his affection for Henrietta. That same night Henrietta hears de Guiche confess his love for her to Raoul. The two pursue their own love affair. Aware of Louise's attachment, the king sends Raoul to England indefinitely as a diplomatic envoy.  Rumours of the king's love affair cause friction with de Wardes, who has inherited from his father a hatred of d'Artagnan and all those associated with him. De Guiche is forced to fight a duel with him and is defeated and seriously wounded. The incident is the last straw for Madame Henrietta who resolves to dismiss Louise from her service as Maid of Honour. The king dissuades Henrietta, but she prevents the king from seeing Louise. The king circumvents Henrietta, and so she contacts her brother King Charles II, imploring him to eject Raoul from England. On his return to France, Raoul is heartbroken to discover Louise in the arms of the king.  Athos finds out everything and spits his contempt at Louis XIV. The young King orders Athos's imprisonment, but D'Artagnan convinces him to release him. CANNOTANSWER
Part Two: Louise de la Valliere (Chapters 94-180)
After 35 years of loyal service, d'Artagnan resigns as lieutenant of the Musketeers as he perceives the young king Louis XIV as weak-willed. He resolves to aid the exiled Charles II to retake the throne of England, unaware that Athos is attempting the same. With their assistance Charles II is restored to the throne and d'Artagnan is rewarded richly.  In France, Cardinal Mazarin has died, leaving Louis to assume power with Jean-Baptiste Colbert as his finance minister. Colbert has an intense hatred for his superior the king's Superintendent of Finances, Nicolas Fouquet, and tries to bring about his fall. He brings to the king's attention that Fouquet is fortifying his fief of Belle Ile secretly. Louis persuades d'Artagnan to re-enter his service, and tasks him to investigate Belle Ile, promising him a substantial salary and promotion to Captain of the King's Musketeers on his return. Louis, finally growing into a decisive ruler, also accepts an offer relayed by Athos from Charles II to marry his brother Philippe I, Duke of Orleans to Charles' sister Henrietta Anne Stuart.  D'Artagnan confirms that Belle Ile is being fortified and the architect ostensibly in charge is Porthos, though the blueprints show the handwriting of Aramis, who is now the bishop of Vannes. Aramis, suspicious of d'Artagnan, sends Porthos back to Paris to warn Fouquet, whilst tricking d'Artagnan into searching for Porthos around Vannes. Porthos warns Fouquet in the nick of time, and he cedes Belle Ile to the king, humiliating Colbert. On returning from the mission, d'Artagnan is made Captain of the King's Musketeers anyway.  Meanwhile, Princess Henrietta arrives in France escorted by the second Duke of Buckingham, to be met by an embassy consisting of Raoul de Bragelonne, his close friend Armand de Gramont, Comte de Guiche, and the Comte de Wardes, son of the previous Comte de Wardes from The Three Musketeers. The erratic Buckingham is madly in love with the princess and can scarcely conceal it, while Guiche soon finds himself equally smitten. Philippe, though little attracted to women, becomes horribly jealous of Buckingham and has him exiled after the wedding. CANNOTANSWER
