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.
