In 1974’s Tinker Tailor Soldier Spy, we finally have an account of George Smiley as a full-fledged intelligence officer after thirteen years on the scene. In the first two novels of the series—Call for the Dead (1961) and A Murder of Quality (1962)—Smiley functioned more as detective that could have easily fit into a G.K. Chesterton Father Brown mystery as he pieced clues together to solve murders. Entertaining, mind you, but not the sort of exploits you expect from a master spy. In the groundbreaking The Spy Who Came in From the Cold (1963), the door was cracked open a little farther and we see him functioning as a ‘puppeteer’ of sorts pulling the surreptitious strings to bring down a communist agent. The Looking Glass War (1965) is almost a footnote; Smiley makes what amounts to an extended cameo that his creator John Le Carré concedes (in a 1991 forward to the then latest paperback) was miscast. It would be a nine-year break between Glass War and Tinker Tailor Soldier Spy but Le Carré wasn’t resting, and he delivered in a very big way.
