The DU Lounge

There are several books in the series, and it wasn't all that long before the XIII gave way to the XIV,, and D'Artagnan worked for himto the end.

in the first sequel, "20 Years After" Athos (who was a Count)) may have been still alive, but was not in the books. His son Raoul more or less replaced him. Raoul was in love with a young woman aso of noble birth, and she sort of was with him but she fell like a stone off a cliff for Louis XIV. Her name was Louise de la Valliere. (also a real person) The next volume was named for her.

Porthos, not born into wealth acquired some and decided to get educated on how to be a gentleman. Dumas's description of him ia thought by many to have been inspired by Moliere's play Le Bourgeois Gentilhomme. Aramis, who in the original Three Musketeers is on again and off again pious, has become a priest and a Jesuit. In the last book, tThe Man in the iron Mask, Aramis more or less gaslights Porthos into joining him in a plot to replace Louis XIV with his identical twin brother to achieve a regime change. The plot fails when the brother refuses to go along with it. Aramis get Porthos out in the ocean in a bot and scuttles it, drowning both, to protect both from the humiliation of being caught, tried, and hanged ignominiously. All of the books also have pretty complex subplots. Reading all in sequence is quite a roller coaster ride.
