" Odd little beggar, Smiley was. Reminded Mendel of a fat boy he’d played football with at school. Couldn’t run, couldn’t kick, blind as a bat but played like hell, never satisfied till he’d got himself torn to bits. Used to box, too. Came in wide open swinging his arms about: got himself half killed before the referee stopped it. Clever bloke, too. "
― John le Carré , Call for the Dead (George Smiley #1)
