It is 1660, and thirty-five years have passed since d'Artagnan and the three musketeers first met in Paris and swore loyalty to each other with their famous cry: 'One for all and all for
one'.
Now, only d'Artagnan remains in the service of the young king, Louis XIV, but royal intrigue, jealousy, a ruthless courtier, and a dark secret, hidden behind the forbidding walls of the
Bastille, are all set to test his loyalty to the limits.
When a secret this dangerous is revealed it must be concealed again at any cost, and little do Aramis, Athos and Porthos realize how destiny will soon entwine their lives on one last
adventure-with the Man in the Iron Mask.
