The Three Musketeers by Alexandre Dumas

The Three Musketeers is a historical adventure novel written in 1844 by French author Alexandre Dumas. It is in the swashbuckler genre, which has heroic, chivalrous swordsmen who fight for justice.

Set between 1625 and 1628, it recounts the adventures of a young man named d'Artagnan (a character based on Charles de Batz-Castelmore d'Artagnan) after he leaves home to travel to Paris, hoping to join the Musketeers of the Guard. Although d'Artagnan is not able to join this elite corps immediately, he is befriended by three of the most formidable musketeers of the age - Athos, Porthos and Aramis, "the three inseparables" - and becomes involved in affairs of state and at court.

In 1625 France, d'Artagnan (a poor young nobleman) leaves his family in Gascony and travels to Paris to join the Musketeers of the Guard. At a house in Meung-sur-Loire, an older man derides d'Artagnan's horse. Insulted, d'Artagnan demands a duel. But the older man's companions instead beat d'Artagnan unconscious with a cooking pot and a metal tong that breaks his sword. His letter of introduction to Monsieur de Treville, the commander of the Musketeers, is also stolen. D'Artagnan resolves to avenge himself upon the older man, who is later revealed to be the Comte de Rochefort, an agent of Cardinal Richelieu, who is passing orders from the Cardinal to his spy, Lady de Winter, usually called Milady de Winter or simply "Milady".

In Paris, d'Artagnan visits Monsieur de Treville at the headquarters of the Musketeers, but without the letter, Treville politely refuses his application. He does, however, write a letter of introduction to an academy for young gentlemen which may prepare his visitor for recruitment at a later time. From Treville's window, d'Artagnan sees Rochefort passing in the street below and rushes out of the building to confront him, but in doing so he offends three Musketeers, Athos, Porthos, and Aramis, who each demand satisfaction; d'Artagnan must fight a duel with all of them that afternoon.
