Fifteen-year-old Christopher has Aperger's Syndrome, a form of autism. He has a photographic memory. He understands maths. He understands science. What he can't understand are other human beings.

When he finds his neighbour's dog, Wellington, lying dead on a neighbour's lawn, he decides to track down the killer and write a murder mystery novel about it. In doing so, however, he uncovers other mysteries that threaten to bring his whole world crashing down around him.

"The Curious Incident of the Dog in the Night-Time" is an astonishing novel - funny, sad and utterly unputdowonable.
