Nice integral collecting the first 4 parts of one of the most famous modern french comic.
The story is heavily inspired by Ludlum's Bourne story, especially in this beginning. Once you dig in, it is very hard to get out as you want to know what happens next ( it is a spy/thriller story).
This specific integral is being published to celebrate the 30 years anniversary of the start of the story and there will be 5 such books published this year, collecting the whole 19 issues story.
