G. K. Chesterton's book The Man Who Knew Too Much was published in 1922, later in the same year that he became a Catholic. These eight dark stories, featuring disillusioned government aide Horne Fisher and crusading journalist Harold March, besides being a collection of mysteries, are also meditations on justice and moral ambiguity in the British Empire on the eve of World War I. "The Hole in the Wall" is a particularly fine murder mystery which comments on the romanticizing of history by prosaic moderns--and which parts of history are not bathed in golden light. The book has a splendid and memorable last line. Chesterton's book has nothing to do with Alfred Hitchcock's two films of the same name.
