The works of John le Carré are not easy to tackle, characters profusion, nesting situations in time including overlapping flashbacks and present time without transitions. The film respects this structure keeping the bulk of roman.Rien to do with 007, the main characters in their fifties or even pensioners. It has a presence, a force that silences that dot the survey only imposes. It is not forbidden to make a second reading of the film to understand the ins and outs which is at the time of the Cold War.
