On its publication in 1964, John le Carré's The Spy Who Came in From the Cold forever changed the landscape of spy fiction. Le Carré combined the inside knowledge of his years in British intelligence with the skills of the best novelists to produce a story as taut as it is twisting, unlike any previously experienced, which transports anyone who reads it back to the shadowy years in the early 1960s, when the Berlin Wall went up and the Cold War came to life.
