The Quest for Karla/YMMV


 * Ho Yay: The letter that Bill Haydon wrote about Jim Prideaux to his Circus talent-spotter.
 * * It Was His Sled: It's quite difficult, especially if you read any later Le Carré novels first, not to know the identity of the Mole in Tinker, Tailor.... However, it doesn't really matter as the identity of the Mole is not really a twist and the real meat of the story is Smiley's investigation and how the Mole was being used.
