Fiona "Feef" Symonds is a young, ambitious, upper-class woman training to become a British secret agent in 1945. It is a great disappointment to her when the war comes to an end and cuts short her career before it has even begun. Instead, Feef takes a job in the civil service and moves to London – but her lover Peter, an American agent, insists he needs her help in rooting out Soviet operatives at the heart of the British establishment.
