Christopher is 15 and lives in Swindon with his father. He has Asperger's Syndrome, a form of autism. He is obsessed with maths, science and Sherlock Holmes but finds it hard to understand other people. 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. "Haddon is to be congratulated for imagining a new kind of hero, for the humbling instruction this warm and often funny novel offers and for showing that the best lives are lived where difference is cherished" -- Carol Ann Duffy Daily Telegraph 20030604 "The clash between Christopher's view of the world and the way it looks to the rest of us makes this an extraordinarily moving, often blackly funny read. It is hard to think of anyone who would not be moved and delighted by this book" -- Jill Slotover Financial Times 20030604 "A stroke of genius, as the advantages of having a naive, literal-minded boy in the driving seat are manifold ... we do learn what it might feel like to have Asperger's Syndrome" -- David Newnham TES 20030507 "Supremely well-written, funny and oddly affecting" Daily Telegraph 20030507 "The book gave me that rare, greedy feeling of: this is so good I want to read it all at once but I mustn't or it will be over too soon" -- Kate Kellaway Observer 20030507
