Looking Glass War, John le Carre

This is almost a satire. Instead of the almost omnipotent Circus from the previous books, the story focuses on another bureau, which is a complete opposite. Where agents carry their real documents with them on a mission, tell state secrets to their families, forget important backstory facts and mostly worry if they’ll be reimbursed for the taxi they took to the office.
Also, this may be a critique to British methods do act as if it’s still WWII, including using outdated and complicated WWII communication devices, because “people are used to them”.
As usual with Le Carre, the preparation to the operation is eighty percent of the book, while the operation itself, if it can be called it, is maybe ten percent.
The book is even more vague what is fact and what is fiction than some other novels, which is interesting. It is never clearly explained who killed Taylor, was the film real or just a setup. And probably that was never the point. As there are also no significant outcomes either, despite the obvious setup by the Circus to the Department, the later seem to continue functioning.
