George Smiley is taken out of retirement to investigate the murder of a former Estonian general. This leads him to his long time adversary Karla, the spy master of the secretive communist spy agency. Considered the end of the Karla trilogy, Smiley sees how much they are both a like. 8/10: not James Bond but a more thoughtful spy novel. I like the idea that spies are actually sad boring people. 😂
