This book by Pierre Martinet begins on the Lebanon war and ends on Gaccio deal with Canal +. This is a very interesting book on ways and learning to become a secret agent of the DGSE secret even if the defense does not reveal everything! Nevertheless the author and former DGSE gives us an overview of the missions of a spy of the XXI century. I recommend this book if you want to know more about our secret services. Well written, it is more loose when it was started.
