Le Carré created Smiley as an intentional foil to James Bond, a character whom he believed depicted an inaccurate and damaging version of espionage life. Short, overweight, balding, and bespectacled, Smiley is polite and and frequently allows others to mistreat him, including his serially unfaithful wife; these traits mask his inner cunning, excellent memory, mastery of tradecraft, and occasional ruthlessness. His genius, coupled with other characters' willingness to underestimate him, allows Smiley to consistently achieve his goals and ultimately become one of the most powerful spies in Britain.
