Frankly I had not read a thriller like this for long. A thriller to the French that reads like an adventure book, that would make a hell of a movie. the characters are endearing (especially veteran Louis G) the incessant action, it pants, it breathes, it goes through a lot of states, and we end the book by saying that we have not wasted time (this which is sometimes the case in the polar ..) there was vibrated and learned things, met different cultures and eras .. thank you for this good book I fail to do adviser. It affects all ages (the hero has more than 80 years !!).
