The stories revolve around the same character, Horne Fisher, who uncovers mysteries that he can't bring to the public eye. In the first story, The Face in the Target, Fisher and two other men come across a dead man at a park. The dead man is a political figure, and Fisher realizes that uncovering the truth could lead to political trouble for the city. Although Fisher usually finds out who has killed the victim, the different circumstances regarding the murders in each of the eight stories usually prevent him from taking further action.
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.
Chesterton's talent as a mystery writer is displayed in this collection of detective stories, The Man Who Knew Too Much. In each story, the star detective, Horne Fisher, deals with another strange mystery: the vanishing of a priceless coin, the framing of an Irish "prince" freedom fighter, an eccentric rich man dies during an obsessive fishing trip, another vanishing during an ice skate, a statue crushing his own uncle, and a few more.

To solve one of the great mathematical problems of his day, Alan Turing proposed an imaginary computer. Then, attempting to break a Nazi code during World War II, he successfully designed and built one, thus ensuring the Allied victory. Turing became a champion of artificial intelligence, but his work was cut short. As an openly gay man at a time when homosexuality was illegal in England, he was convicted and forced to undergo a humiliating "treatment" that may have led to his suicide.
