Le Carré, who created Smiley, wanted to show that Ian Fleming's James Bond series was an inaccurate picture of espionage life. Smiley is polite, shy and humble. He often allows others to mistreat him, especially his unfaithful wife. But his humility masks his inner cunning, excellent memory, mastery of tradecraft, and occasional ruthlessness. His genius being underestimated helps Smiley achieve his goals. In the end, he becomes one of the most powerful agents in Britain.
