Quiller is a fictional character created by English novelist Elleston Trevor. Quiller, whose one-word name is a pseudonym, works as a spy, and he is the hero of a series of Cold War thrillers written under the pseudonym Adam Hall, and became Trevor's most popular character. The books concern a solitary, highly capable operative who works, usually on his own, for a British government organization, referred to as "The Bureau", which "doesn't exist".
