The Man Who Knew Too Much and other stories is a book of detective stories by English writer G. K. Chesterton.Horne Fisher is extremely well connected. The plans of prime ministers, foreign ambassadors, and chancellors are matters of table conversation—usually because these people are dining with him. And when a man so well connected is also a brilliant detective, all sinister motives and plots systematically unfold. Whether it is a case of police corruption, or a war with Sweden, Horne Fisher can always solve it. But Horne Fisher is also a philosopher, and not a policeman, and the murderer is seldom punished. G. K. Chesterton, author of the Father Brown stories, here introduces another detective outside the realm of conventional law enforcement.
