On his way through the village of Meung, the young man is involved in a fight with a mysterious gentleman, being unconscious. When he recovers, he discovers that his cover letter has been stolen.

Already in Paris, D'Artagnan will live an endless number of adventures with his new and inseparable companions Athos, Porthos and Aramis. And he'll still have time to win Constance's love and solve an intriguing palace case.
