Paul McNamee of The Big Issue looks at Karla's Choice and is pleased with what he finds -
"It’s a great book, completely consumable. It has John Le Carré’s dash, that odd ability to immediately hook you into a world that should be alien but immediately feels familiar and one that you just want to stay in. You can smell the Circus and its closed dank rooms in 1963. The book understands that what Le Carré was doing, what the best of great world genre writers like him and Simenon and Ambler and Matsumoto did, was not simply tell stories, but create worlds, into which we link and sink forever."
