The Three Musketeers

The story

Young d'Artagnan arrives in Paris from Gascony with a letter, a yellow horse and a hot temper. On his first day he challenges three musketeers — Athos, Porthos and Aramis — to three duels.

Instead of fighting each other, the four become inseparable friends and race to save the Queen's honour from Cardinal Richelieu and the dangerous Milady de Winter.

Themes: friendship and loyalty, honour, court intrigue, 17th-century France.

Why it's a good book for language learners

Dumas writes fast, funny dialogue and keeps the plot moving with cliffhangers. The four friends have very different personalities and ways of speaking, which helps you hear different registers. In French it is a cornerstone classic for intermediate readers.

How hard is the English in The Three Musketeers?

• Flesch Reading Ease73.7
• Flesch–Kincaid grade6.6
• Words per sentence14.7

Measured by PageWalker on the full English text of the book. Flesch Reading Ease runs from 0 to 100 (higher is easier; 60–70 is plain English) and the Flesch–Kincaid grade is a US school grade. These formulas only count sentence and word length, so they miss old-fashioned vocabulary, wordplay and style. That is why our CEFR level, which takes those into account, can be higher than the formula suggests.

Contains spoilers. Read one part of the book, then come back to check you followed it.

Chapters 1–7: A young man comes to Paris

Young d’Artagnan leaves Gascony with an old yellow horse, fifteen crowns and a letter for Monsieur de Tréville, captain of the King’s Musketeers. In the town of Meung a mysterious stranger laughs at him, and his letter is stolen. In Paris he bumps into three Musketeers, Athos, Porthos and Aramis, and agrees to fight a duel with each of them. But the cardinal’s guards arrive, and d’Artagnan fights beside the three men instead. They win, and King Louis XIII is pleased.

Chapters 8–18: The queen’s secret

D’Artagnan’s landlord, Bonacieux, tells him that his young wife Constance, who works for the queen, has been kidnapped. The four friends swear their motto, “All for one, one for all.” D’Artagnan saves Constance from the cardinal’s men and falls in love with her. Queen Anne secretly gives the Duke of Buckingham twelve diamond studs. Cardinal Richelieu learns of it and asks the king to make the queen wear the studs at a ball. Constance asks d’Artagnan to bring them back from London.

Chapters 19–24: The journey to London

The four friends ride toward the coast, but enemies attack them on the road. Porthos, Aramis and Athos are left behind one by one. D’Artagnan reaches London alone. Buckingham finds that two studs are missing, because Milady de Winter, a spy of the cardinal, has cut them off. A jeweler quickly makes two copies, and d’Artagnan returns in time. The queen wears all twelve studs at the ball and gives him a ring. Soon after, Constance is kidnapped again.

Chapters 25–28: Finding the friends

D’Artagnan goes back to find his friends. Porthos is at an inn in Chantilly, hurt after a duel. Aramis is at Crèvecœur, writing a thesis and talking about becoming a priest. Athos has locked himself in a wine cellar at Amiens. While drunk, Athos tells a sad story about a count who married a beautiful girl and later found a fleur-de-lis brand on her shoulder, the mark of a criminal. The four friends return to Paris together.

Chapters 29–40: The secret of Milady

The friends need money for equipment before the war. D’Artagnan meets Milady and fights her brother-in-law, Lord de Winter, but spares his life. With the help of Kitty, Milady’s maid, he tricks Milady and discovers the fleur-de-lis on her shoulder. She is the wife of Athos, and now she wants to kill d’Artagnan. Cardinal Richelieu invites d’Artagnan to serve him, but d’Artagnan politely refuses and stays loyal to his friends.

Chapters 41–50: The siege of La Rochelle

The army goes to fight at La Rochelle. Milady’s men try to kill d’Artagnan, and poisoned wine kills one of his men. At an inn, the Musketeers hear the cardinal give Milady a secret mission against Buckingham. Athos takes from her a paper signed by Richelieu that protects whoever carries it. The friends eat breakfast in a dangerous bastion to talk in private and win a bet. They send warnings to England, and Lord de Winter arrests Milady when she arrives.

Chapters 51–59: Milady in prison

Lord de Winter keeps Milady locked in his castle and gives the young officer Felton the job of guarding her. Over five days, Milady plays the part of an innocent, religious woman who has suffered greatly. She tells Felton false stories until he believes her and falls under her power. Felton helps her escape and sends her to France on a ship. Then he goes to Portsmouth and kills the Duke of Buckingham with a knife.

Chapters 60–67: Justice and the end

Milady hides in a convent at Béthune, where Constance is also staying. When she learns that d’Artagnan is coming, she poisons Constance, who dies in his arms. The friends, Lord de Winter and a man in a red cloak, the executioner of Lille, catch Milady, judge her and execute her. Back at camp, Rochefort arrests d’Artagnan. He shows Richelieu the signed paper, and the cardinal gives him a lieutenant’s commission. His friends refuse it, so d’Artagnan becomes lieutenant.
