Smiley himself was one of those solitaires who seem to have come into the world fully educated at the age of eighteen. Obscurity was his nature, as well as his profession. The byways of espionage are not populated by the brash and colourful adventurers of fiction. A man who, like Smiley, has lived and worked for years among his country's enemies learns only one prayer: that he may never, never be noticed. Assimilation is his highest aim, he learns to love the crowds who pass him in the street without a glance; he clings to them for his anonimity and his safety. His fear makes him servile - he could embrace the shoppers who jostle him in their impatience, and force him from the pavement. He could adore the officials, the police, the bus conductors, for the terse indifference of their attitudes. (ch. 9)
