If you want a more realistic and mature espionage thriller who truly understands the current geopolitical structure with no bias, John Le Carre is on the top of the hierarchy. Not like Ludlum, Forsyth, and Fleming that puts the action and naked women at the center of the story, John Le Carre puts the issue (usually this issue is global) and the mystery at the center. In a Le Carre novel, there is no clear line that separates good and evil. If there ever was, the reader will realize that it was just a mirage, an illusion. There is no black and white. His stories are paradoxical that will make the reader think, and think again. Anyway, let's wait for the movie. We just hope that this movie is as good as the book.
Spy film of the year? We hope so.
