The Curious Incident Of The Dog In The Night-Time has won the Whitbread Book of The Year, it's been announced.
The novel, which was published for both children and adults, is about a 15-year-old with a form of autism who turns detective to solve a murder.
Judges said they were really impressed with the book because author Mark Haddon "used disability to throw light upon the world."
As the overall Whitbread winner he picked up a cheque for £25,000.
Earlier on this month the book won the Whitbread award for "best novel".
