Christopher Boone is fifteen and sees the world differently from most people. He knows every prime number up to 7,057, cannot bear to be touched, and reads faces and social situations only with great effort. When he discovers his neighbour's dog, Wellington, killed with a garden fork, he decides to investigate the crime and to write a murder-mystery novel about it — modelled on the Sherlock Holmes stories he loves.
Christopher's methodical inquiry, though, keeps leading him past the dog and into the far more bewildering territory of his own family. As he uncovers things his father would rather he never knew, his careful, ordered world is upended, and he is forced onto a terrifying journey that takes far more courage than any maths problem.
Narrated entirely in Christopher's precise, literal, and often very funny voice, Mark Haddon's The Curious Incident of the Dog in the Night-Time is a crossover phenomenon and a modern classic. It is a mystery, a coming-of-age story, and a compassionate portrait of a mind that works by its own uncompromising logic.
