I am currently reading my way through a long list of science fiction and fantasy titles. (http://www.npr.org/2011/08/07/138938145/science-fiction-and-fantasy-finalists if you are interested in the list).
In London at dead of night, George Smiley, sometime acting Chief of the Circus (aka the British Secret Service), is summoned from his lonely bed by news of the murder of an ex-agent. Lured back to active service, Smiley skillfully maneuvers his people -- the no-men of no-man's land -- into crisscrossing Paris, London, Germany, and Switzerland as he prepares for his own final, inevitable duel on the Berlin border with his Soviet counterpart and archenemy, Karla.
***2018 Summer of Spies***
In the spy genre, if James Bond is a boxing match, then George Smiley is a chess game. Lots of planning ahead, knowing your opponent, and biding your time to make the right move. Smiley and Karla match wits again, but George has a new advantage—Karla can no longer manipulate him via his wife.
Fans of fist fights and gun battles may find this boring. People like myself, who have spent many years researching and working within libraries and archives, will find ourselves mesmerized as Smiley reads files and interviews other ex-employees of the intelligence services in order to build the perfect mousetrap.
