My first Le Carré ever. Quite an entertaining read, I could barely drop it after I started. Got 4 stars, not 5, because some aspect of the plot are, nowadays, a little bit on the beaten trope side. It's also curious (not sure if curious is the right word) that they market it as a George Smiley novel although the character is quite so very small in the story. But, well, technically he is there. Already got myself Tinker, Tailor, Soldier, Spy.
