My edition of the Collected Works of Alexandre Dumas explains that The Vicomte de Bragelonne was originally published as a massive work but is traditionally published in English as either three or four separate novels: The Vicomte de Bragelonne, Ten Years Later, Louise de la Valliere, and The Man in the Iron Mask. I read the first book, which was quite long in itself.
I felt I was at a disadvantage in reading this book because it is one of the D’Artagnan novels and I haven’t read The Three Musketeers for many years or Twenty Years After ever. Although all four of the original characters appear, I felt that I didn’t understand their relationships to each other. As for the title character, who is the son of Athos, although he makes a couple of appearances, this first novel in the set is about D’Artagnan.
In the beginning of the novel, Louis XIV is a young king, but he has been under the control of Cardinal Mazarin for most of his life. D’Artagnan is the lieutenant of the musketeers, and he overhears when Charles II of England comes penniless to the king to ask for money and men to take back his kingdom. Louis’s finances are kept strictly in the Cardinal’s hands, so Louis goes to the Cardinal to ask for the money or men. The Cardinal, who has made himself wealthy at the kingdom’s expense, tells Louis there is no money and he can’t spare any men. When D’Artagnan sees Louis send Charles away with nothing despite wanting to help him, he resigns in disgust, determined to help Charles.
D’Artagnan’s friend Athos, now the Comte de la Ferre, also wants to help Charles. He was present at the beheading of Charles’s father and knows the Charles I buried a million livres at Newcastle. Athos determines to fetch the money.
This novel seems disjointed. More than half of it deals with the two missions on behalf of Charles, while the rest deals with Louis finally coming into power and sending D’Artagnan on a mission. Perhaps as a complete work, with all its parts, it would seem more coherent, but at this time I was not willing to put in the time to read the whole thing.
I read this for my Classics Club list.

I enjoyed this, but I read the whole series in order and I can see how this book could be confusing if you hadn’t read Twenty Years After first.
Yes, it definitely should be done that way. Maybe I’ll put The Three Musketeers on my next Classics Club list, as I am almost done with this one. I’ve been thinking about putting a couple of books by some of the authors instead of just one, so I could read both that and Twenty Years After. Did you read all of the books included in The Vicomte de Bragelonne? That volume by itself was really long.
