When the day of the duels comes, the four men are interrupted by the Cardinal's guards (the sworn enemies of the musketeers), and they join forces in order to fight their enemies. From this day forth the four men become firm friends and go on a number of adventures. One of which is to save the blushes of the Queen of France, when the cardinal hopes to sow mistrust between her and the King. The Queen gives away twelve diamonds that were a present from the King to her lover, Buckingham, and in order to trap her, the cardinal sends a spy, M'lady to steal two of the diamonds so they cannot be returned.
The plots on the young man's life never quite succeed and finally he, along with his three friends, catches up with M'lady and execute her for her many crimes. The cardinal (realising that the young men may uncover his treachery) offers D'Artagnan a commission to the King’s guard, which he accepts, becoming a musketeer.
The Three Musketeers: Controversy and Questions
The Three Musketeers, is not merely a adventurous, high-flung Romance with a historical setting, it is also a keen investigation into the historical milieu that Dumas has chosen as his setting. Many of the characters are historical figures (particularly the shadowy Cardinal Richelieu), and much of the book is based on historical fact.
Although we are supposed to thrill at the adventures of D'Artagnan and his friends, we are also left in little doubt that there actions are often highly questionable. Though they speak in a code of honor and gentilesse, the musketeers are often philanders and cheats. They are also often violent with little cause.
With a brilliantly constructed plot and a set of characters large enough to easily become legends, The Three Musketeers is a great adventure story for all ages. However, it is also a brilliantly researched and thought-out historical novel. Dumas doesn't attempt to plaster over the inconsistencies and corruptions of the times.
