The d'Artagnan romances are now concluded and I am terribly sad (there is a postumously published story that takes places between The Three Musketeers and Twenty Years After but it won't be the same)

This is a trilogy (if you don't count the last book being broken into 4 separate works) that begins as a comedy and adventure, progresses into a romance, and ends as a tragedy. Many complain that the book left unanswered questions, but isn't that the case in a life?

If you have seen the Hollywood production The Man in the Iron Mask from 1988, just go ahead and throw it out of the window. They are not the same story, just based on the same premise.

What is most interesting about these books, there really was a man in an iron mask at the Bastille. Though history has lost who this person was, there is much debate and is a major source for The Man in the Iron Mask.
Also d'Artagnan was based on a real musketeer as well as Athos, Porthos, and Aramis. Though the stories at fictionalized, the wikipedia read about Charles de Batz-Castelmore, the real d'Artagnan is very interesting as well.

This series is very long, but I recommend it. What an amazing story of friends, power, politics, and adventure.
