What if knowing who committed a crime only makes justice harder to reach?
In G. K. Chesterton’s The Man Who Knew Too Much, eight linked detective stories lead into the country houses, clubs and committee rooms of Edwardian England. Horne Fisher belongs to this world. Clever and weary, he knows the ruling class and its secrets. A death or disappearance gives him a puzzle, but the answer brings harder questions.
Beside Fisher walks Harold March, a young, honest journalist who learns how difficult the truth can be to print. From crimes among sporting gentlemen to secrets tangled with finance and foreign affairs, these mysteries explore a society that protects its own. Fisher can see what happens behind closed doors. Knowing what to do about it is another matter.

“Chesterton lays great stress on the youth of Dickens; it is only right that he should do this; the early life of Dickens was probably responsible for the wonderful genius of his art.”
In short
A tall, bald man sits on a rock in a stream, dipping a child's net into the water and catching nothing. Moments later a motor car flies off a cliff and an old judge lies dead on the grass.

A fisherman with no fish solves a murder
The book opens on a moor in the west of England. Harold March, a young reviewer, drops into a narrow stream valley and finds a tall, pale man dipping a toy net into the water. He gives his name as Horne Fisher and says he studies glowing sea creatures.
Then a huge motor car shoots over a cliff and crashes below. The driver is Sir Humphrey Turnbull, an old judge who was once a terror in the courts. Fisher doubts the man took his own life. At a shabby inn they learn the judge filled a flask and bought sandwiches. March remarks that a guest bound for a grand house would hardly carry sandwiches, and Fisher seizes that small remark and builds on it.
