The Last Mercenary

The mercenary Richard Brumaire, also known as "La Mist" (codename "Mist"), was once a mysterious French Secret Service agent. He was forced to return to his old profession after the immunity he had secured for his son Archibald 25 years earlier was revoked. When a crime threatens Archibald's life, Richard has no better choice than to turn to his old acquaintances and team up with a group of reckless young men and an offbeat bureaucrat to save his son. But the most important thing for Richard was finding the courage to let Archibald know that he was his father.
