The Story

D'Artagnan leaves his native Gascony carrying fifteen crowns, an aging yellow horse, a letter of introduction from his father to Monsieur de Tréville, captain of the King's Musketeers, and a jar of his mother's healing balsam — his whole inheritance, staked on reaching Paris and a Musketeer's uniform.

His father, M. d'Artagnan the Elder, a battle-worn Gascon noble who once fought beside King Henry IV, presses on his son three hard rules: fear no one but the Cardinal and the King, and let courage, not birth, open every door. His mother, Mme. d'Artagnan, adds only her tears, having already packed the promised balsam.

At the inn in Meung, a mysterious gentleman in violet mocks D'Artagnan's comical horse, so D'Artagnan draws his sword in fury. The stranger's men fall on him instead, beating him unconscious before he lands a single blow, and the gentleman vanishes into the crowd unpunished.

D'Artagnan revives thanks to his mother's balsam, only to discover his letter to Tréville is gone, stolen while he lay senseless. Certain the violet gentleman took it, he rides on to Paris burning for revenge and desperate for the patronage that letter was meant to secure.

In Tréville's Paris antechamber, D'Artagnan meets two Musketeers, Porthos and Aramis, waiting among the company. A third, Athos, is said to be laid up ill, though rumor suggests a wound instead — D'Artagnan's first glimpse of the trio he will soon call friends.

Tréville furiously reprimands Porthos and Aramis for letting Cardinal's Guards get the better of them in a public brawl the day before, since every such defeat humiliates his Musketeers and hands Cardinal Richelieu fresh ammunition against the King's own guard.

When D'Artagnan describes his attacker, Tréville recognizes the man and recalls seeing him meet a woman called Milady before departing for London with a locked box. The detail means nothing to D'Artagnan yet, but it ties his private grudge to affairs far larger than a stolen letter.

Spotting his tormentor from a window, D'Artagnan bolts downstairs in pursuit, but in his haste he jostles Athos's wound, tangles Porthos's cloak to expose its cheap backing, and snatches up a letter Aramis is hiding. Each insult earns him a duel, three fights arranged for the very same hour.

Before the duels can finish, Cardinal's Guards under Jussac interrupt and demand their surrender, so the four Frenchmen turn as one against the common enemy instead. They rout the guards together, crying "all for one, one for all!" as Dumas wrote, and though Richelieu complains, the King rewards them all.

Weeks later D'Artagnan quarrels with the Cardinal's Guardsman Bernajoux at the tennis courts and wounds him badly in a fresh duel, which spills into a full street brawl between Musketeers and Guards drawn by the commotion.

Bernajoux, dying, confirms D'Artagnan's account of the fight, so the King grants him forty pistoles and a cadetship in the Guards as reward. Cardinal Richelieu, furious at seeing his own man discredited and D'Artagnan promoted, withdraws from court in anger for over a week.

D'Artagnan's landlord, Bonacieux, comes to him distraught: his wife Constance has been abducted by the Cardinal's agents. She serves the Queen and knows a dangerous secret — that the Queen fears a forged letter lured the Duke of Buckingham to Paris — knowledge that made her a target.

When the Cardinal's guards set an ambush at Bonacieux's apartment, Constance walks straight into it, so D'Artagnan fights the men off and rescues her himself. Unable to keep her safely at his own lodging, he hides her instead at Athos's rooms, out of the Cardinal's immediate reach.

Trailing Constance, D'Artagnan discovers she is secretly meeting the Duke of Buckingham himself and offers her his protection and service. Meanwhile the Cardinal's men, hunting D'Artagnan, arrest Athos in his place at his lodging; Athos accepts the mistaken arrest calmly, buying his friend precious time.

Buckingham and Queen Anne of Austria meet in secret, and she admits feelings long suppressed. As a parting keepsake she gives him something reckless: a set of diamond studs, the King's own gift to her, now carried off to England as a token of forbidden love.

Cardinal Richelieu learns the Queen gave away the King's diamond studs and seizes the opening, pressing the jealous King to test her fidelity. He arranges a ball where she must wear the studs publicly, timing it precisely so her almost-certain failure will expose and ruin her.

With Bonacieux refusing to help his own wife's cause, D'Artagnan volunteers to retrieve the studs from Buckingham before the ball, even seizing bribe money the Cardinal had meant for Bonacieux to fund the ride. Tréville forges leave papers, and Athos, Porthos, and Aramis ride for London with him.

The journey to London picks the friends off one by one. Porthos stays behind at Chantilly after a quarrel forces him into a duel, and Aramis, wounded near Beauvais, cannot continue either, leaving the mission thinner with every stage of the road.

At Amiens, a false charge of counterfeiting traps Athos in an inn cellar, and he stays to fight off his accusers so the others can escape. Only D'Artagnan and his servant Planchet reach the Channel coast at all, the mission now resting on one rider alone.

In London, Buckingham learns that Milady, working for Cardinal Richelieu, has already stolen two of the twelve studs to sabotage the Queen. He embargoes every English port to stop the news reaching Paris and orders the goldsmith O'Reilly to forge exact replacements within three days.

At the Cardinal's ball, Richelieu triumphantly reveals that only ten studs should remain on the Queen — but she appears wearing all twelve, the replacements delivered just in time. Her plot foiled his instead, and she rewards D'Artagnan, the courier who saved her, with a diamond ring.

Tréville warns D'Artagnan that the Queen's ring now marks him as a target. Arriving for a rendezvous with Constance at St. Cloud, he finds the pavilion ransacked and Constance gone again, abducted a second time, and learns her own husband identified her to the men who took her.

Setting out to gather his scattered friends, D'Artagnan finds Porthos still bedridden at Chantilly, mercenarily courting Madame Coquenard, a wealthy procurator's wife, purely for the money he needs to campaign — vanity and poverty forcing a courtship he treats as a business transaction.

Porthos promptly gambles away his own horse, worsening his finances further. Madame Coquenard, suspicious of his motives, withholds the full funding he wants, doling out only enough to keep him interested — so Porthos, needing her money badly, keeps courting her regardless of the insult.

D'Artagnan moves on from Porthos's sickroom to track down Aramis, the last of his scattered friends still unaccounted for since the ride toward London began.

D'Artagnan finds Aramis recovering under the care of theologians, who have nursed his wound and steered him toward the priesthood he once wavered over. He seems nearly ready to abandon the sword altogether and take holy orders, the soldier's life almost behind him.

A letter arrives from a mysterious noblewoman, and reading it changes Aramis instantly: he sets aside his theology books as worldly ambition floods back in. He decides to rejoin his friends after all, the priesthood postponed once again by a woman's handwriting.

Reunited, the four Musketeers duel four visiting Englishmen, and D'Artagnan recognizes his opponent as Lord de Winter, a gambler he'd seen before. Learning de Winter is Milady's brother-in-law, D'Artagnan spares his life for her sake, and the grateful Englishman introduces him to Milady herself.

Pursuing Milady, D'Artagnan learns through her maid Kitty that she truly desires the Comte de Wardes, not him. So he forges a letter in de Wardes's name and, in darkness, impersonates the man himself, winning a night with Milady and a sapphire ring as her token.

Athos recognizes the sapphire ring on D'Artagnan's hand as his own family heirloom, one he gave to a wife long ago. Shaken, he warns D'Artagnan that Milady is far more dangerous than he realizes, though he does not yet explain why he knows the ring so well.

When the real Comte de Wardes reveals he never wrote such a letter, Milady realizes she was deceived, and D'Artagnan foolishly confesses he was the impostor himself. Enraged and denied her revenge, Milady attacks him with a dagger, tearing his glove and exposing a fleur-de-lis branded into her shoulder.

Hearing the brand described, Athos recognizes Milady as the wife he married years ago as the Comte de la Fère, a woman he discovered was a condemned criminal and believed he had hanged for it. She has survived, and now stands revealed as his own supposed victim.

Cardinal Richelieu, needing an agent against Buckingham, sends Milady to England armed with a blank authorization to act in his name. Athos intercepts her at an inn before she sails and forces her to surrender the document, proof of the Cardinal's complicity, though she departs regardless.

At the siege of La Rochelle, D'Artagnan is twice ambushed by assassins working for Milady, surviving both attempts on his life. A captured assassin's letter later confirms the plot against him and reveals where Constance is now hidden, in a convent at Béthune.

In England, Lord de Winter learns the full truth of Milady's branded past and her prior marriage, so he imprisons her under armed guard rather than let her act against Buckingham again, assigning a young Puritan officer, Felton, to watch her day and night.

Milady works on Felton relentlessly, fabricating a story that Buckingham once drugged, ravished, and branded her unjustly, and staging a fake suicide attempt to prove her despair. The devout young officer, horrified and moved, falls completely under her spell and vows to help her.

Felton frees Milady and, convinced Buckingham is a villain who must be stopped before his fleet sails, stabs him to death in his own chamber. Buckingham dies moments after reading a final letter from Queen Anne urging peace, delivered too late to change anything at all.

Milady reaches the Béthune convent first and wins Constance's trust by posing as a friend. Just as D'Artagnan's rescue party arrives, Milady poisons Constance from a substance hidden in her own ring, and Constance dies in D'Artagnan's arms, moments too late for rescue.

Servants track Milady's carriage to a house at Armentières, where the four friends, Lord de Winter, and a mysterious man in a red cloak surround her at night. They convene an improvised trial, charging her with poisoning Constance, hunting D'Artagnan, and orchestrating Buckingham's murder.

The man in red reveals himself as the executioner of Lille, who branded Milady years before for ruining his brother, a priest driven to suicide by her. Condemned unanimously by the tribunal, Milady is beheaded on the riverbank, her body thrown into the river Lys.

Back in Paris, Rochefort, the Cardinal's agent, arrests D'Artagnan on Cardinal Richelieu's orders, dragging him before the very minister who set Milady's mission in motion in the first place.

D'Artagnan tells Richelieu of Milady's execution and produces the Cardinal's own signed authorization as proof of what she was sent to do. Rather than punish him, Richelieu forgives D'Artagnan outright and formally reconciles him with Rochefort, ending their long rivalry on the spot.

Richelieu had prepared a punitive order against D'Artagnan, but instead tears it up in front of him. In its place he writes out a blank commission naming D'Artagnan a lieutenant of the Musketeers, turning the punishment he had planned into the reward of a lifetime.

D'Artagnan offers the blank commission in turn to each of his three friends. Athos refuses it, considering himself unworthy of formal rank; Porthos refuses, set on marrying into wealth instead; Aramis refuses too, his mind now made up for the Church rather than the sword.

With none of the others willing to take it, Athos settles the matter himself: he takes up a pen and writes D'Artagnan's own name onto the blank commission, securing it for the one friend who has earned it and wants it most.

La Rochelle surrenders on the twenty-eighth of October, 1628, after a year-long siege, its hoped-for English relief lost with Buckingham's death. The King enters Paris in triumph on the twenty-third of December, the long campaign that shaped every friendship and betrayal in the story finally over.

Porthos marries the newly widowed Madame Coquenard, inheriting her considerable fortune along with her hand, the mercenary courtship he began purely for money ending, fittingly, in exactly the wealth he had always wanted.

Aramis retires at last to a convent in Lorraine, choosing the priesthood he had wavered over throughout the story. Athos serves on a few more years before retiring to his estate in Roussillon in 1633, the eldest of the friends finally setting down his sword.

Dumas follows Porthos, Athos, and Aramis no further than these settled fates: the wealthy husband, the retired seigneur, and the cloistered priest each vanish from the page the moment his story resolves, so whatever years remained to any of them lie forever outside the novel's own telling.

As for D'Artagnan, the novel grants him only one more scene, a final settling of accounts with Rochefort, and follows him no further afterward. Whatever campaigns, loves, or dangers awaited the young Gascon in the years beyond, Dumas leaves them entirely untold, closing the tale at its brightest turn.

D'Artagnan duels his old enemy Rochefort three separate times, wounding him in each encounter, until the two former rivals, tested against each other again and again, finally become genuine friends — the last of the story's old hostilities laid to rest.

What it means

D'Artagnan's private grief for Constance and the great political conspiracy against Buckingham turn out to be the same story all along, both driven by the same woman, both ending together on that riverbank — personal vengeance and international intrigue, braided from the first pages, severed by one blade.
