Born to "parents in European banking" with a "small aristo" background Prideaux was raised abroad and attended
Oxford. Smiley recalls that Jim was at first more athletically gifted than academically, but he came to excel in linguistics and was a
polyglot. During his time at Oxford, Prideaux was befriended by
Bill Haydon, a young Circus agent who recruited him to the organization. The two were lovers and remained close friends throughout their careers in the Circus. Prideaux has a gruff demeanor, which Smiley likens to that of a soldier, and speaks in short, clipped sentences; this demeanor disguises an intelligent mind, and he is essentially kind, especially towards children. Following WWII, Prideaux briefly works as a teacher before rejoining the intelligence services. He works at the Circus for three decades, primarily in Czechoslovakia, and is head of the Balkans desk by 1960. Mostly retired, he lives on the grounds and coaches junior rugby. == Development ==
