I didn't realize at first that this was the 3rd book in the 'Three Musketeers' trilogy (Of which I hadn't read the first two), so it took a while to understand all the characters. Despite that, Dumas is definitely one of my favourite authors, and this book is another great book from him! Though the book is barely about 'the man in the iron mask', instead concluding the life stories of the famous three (four?) musketeers, haha.
