The Bureau
"Le Bureau des Légendes"
https://www.imdb.com/title/tt4063800/?ref_=fn_al_tt_1
A very good intelligence/counterintelligence series about the
"bureau des légendes", the mythical powerhouse within the French Secret Service and its daredevil ghost agents".
5 seasons, 50 episodes total, episodes about an hour long. One of the best series I've watched in the last year. There are layers upon layers of deception and guessing going on in multiple intelligence networks with the focus being on the French agency. Good acting, believable characters, constant guessing by the viewer as to what's going on and what's going to happen. 2 oddly-attractive female agents doesn't hurt. I thought it was a hell of a good series.
