D'Artagnan, a young Gascon youth, sets out from his village with the hope of joining the regiment of the King's Musketeers. As soon as he arrives in Paris he gets into trouble, first entangling himself in one, then two and finally three duels, all in one day! And with men from the very regiment of Musketeers he had hoped to join! But his adventures don't stop there; before long, he becomes involved with the affairs of the Queen, Anne of Austria, herself and must enlist the help of his fellow Musketeers Athos, Porthos and Aramis. Together, the four friends journey through France escaping from the nets of the Cardinal and his dangerous spy, Milady, while all the time fighting duels at the slightest provocation.
I love the summary given at the back of the Wordsworth edition. It describes the book perfectly,
The characterization in this novel - especially of Milady and Athos - was so good that I actually wanted to meet the characters! The movie on The Three Musketeers does not do justice to either character. Milady reaches depths of evil and horror which aren't shown in the film. All we see is an ambitious young woman who despite what she does, loved someone once and wasn't truly evil. But in the novel, the description of Milady and the suppressed animal within, how she is able to ensnare anyone while putting on an act, her ability to sense every weakness in man - all are so wonderfully drawn. As for Athos, he is shown as the true nobleman that he is, and his quiet way of handling even the most alarming of situations makes him particularly attractive while at the same time remaining mysteriously charming. Though not the hero of the novel, he is the most important character and the leader of the Musketeers; Keith Wren, in his introduction to The Three Musketeers sums it up when he writes,
I keep forgetting that The Three Musketeers is historical fiction. The Cardinal Richelieu, King Louis XIII and Queen Anne were actual historical figures, as was the Duke of Buckingham and his murderer, Felton. Alexandre Dumas has fashioned a unique story with these real live characters. It was rumored that the Duke was in love with the Queen of France (this is also mentioned in The King's General), and in this novel the flirtation was embellished, with Queen Anne and the Duke having many secret meetings. The various love triangles in this novel make for a lot of intrigues, a lot of duels, and most of all, a lot of jealousy!
