A Murder of Quality (George Smiley #2) by John le Carré

John le Carré's classic novels deftly navigate readers through the intricate shadow worlds of international espionage with unsurpassed skill and knowledge, and have earned him -- and his hero, British secret Service Agent George Smiley -- unprecedented worldwide acclaim.

George Smiley was simply doing a favor for Miss Ailsa Brimley, and old friend and editor of a small newspaper. Miss Brimley had received a letter from a worried reader: "I'm not mad. And I know my husbad is trying to kill me." But the letter had arrived too late: it's scribe, the wife of an assistant master at the distinguished Carne School, was already dead.

So George Smiley went to Carne to listen, ask questions, and think. And to uncover, layer by layer, the complex network of skeletons and hatreds that comprised that little English institution.

Novels by John le Carré in which the character George Smiley appears - with the exception of The Karla Trilogy, these are standalone works and can be read in any order. (In four out of nine of them, Smiley is only a minor character.)
