The Curious Incident of the Dog in the Night-time is about an autistic child who discovers a dead dog with a pitch-fork in his body. He decides to play a detective, trying to solve who committed the murder. However, when the mystery is solved, the book takes on a different theme. This revolves around the boy's journey, both physical and emotional.
I get the feeling from reading this book that Haddon really understood autistic children. I even think that he did a very good job of encapsulating some of the behaviours, actions and emotions of an autistic child, coping with the complex world around them. However, I just do not have the feeling he completely nailed the experience on the head. I don't have much backing as to why I believe this (as I didn't write down quotes this time), but certain things he says and I'm paraphrasing "and then I groaned to drown out the noise," just don't seem to be in a state that I would believe an autistic mind is in. This may be what the autistic child is DOING, but I doubt that this is what he is THINKING.
However, the book was written in a way that makes the reader think differently about the world. The prose is very simple, but the ideas are very complex. Certain things you would not explore on a regular basis or give any second thoughts to, are explained in a wonderful way that really shows you how unique a perspective some of these autistic individuals have. It is in this perspective that Haddon shines, and makes this book a very enjoyable read.
