Christopher is 15 and lives in Swindon with his father. When he discovers a dead dog on a neighbour's lawn he decides to solve the mystery and write a detective thriller about it. As in all good detective stories, however, the more he unearths, the deeper the mystery gets - for both Christopher and the rest of his family.

The multi-million-copy bestselling phenomenon, and a mystery story like no other.

'Brilliantly inventive . . . This isn't simply the most original novel I've read in years. It's also one of the best' The Times

'Outstanding' Observer

'A remarkable book' Time Out

Christopher is fifteen and autistic. He knows a very great deal about maths and very little about human beings. He loves lists, patterns and the truth. He hates the colours yellow and brown and being touched.

Christopher has never gone further than the end of the road on his own. But when he finds a neighbour's dog murdered, he sets out on a journey which will turn his whole world upside down.

'Exceptional by any standards . . . When we look at the world through Christopher's eyes we see it more clearly and understand ourselves better. What more could you want of a book?' Sunday Telegraph

'I have never read anything quite like Mark Haddon's funny and agonizingly honest book, or encountered a narrator more vivid and memorable. I advise you to buy two copies; you won't want to lend yours out' Arthur Golden
