Christopher, an autistic teenager makes us the story of the investigation that leads to find the "murderer" of his neighbor's dog. He is autistic seems remote, down the world around him and yet the story is engaging, full of depth, at times funny, sad and even tragic often. The story goes on well beyond Christopher's detective work reveals how to see things from an autistic child or to be more precise as understood by the author. One of the finest books I had to read.
