What do you think spies are: priests, saints and martyrs? They're a squalid procession of vain fools, traitors too, yes; pansies, sadists and drunkards, people who play cowboys and Indians to brighten their rotten lives.
(John le Carré (b. 1931), British novelist. Leamas, in The Spy Who Came in From the Cold, ch. 25 (1963).)
