the curious incident of the dog in the nighttime

After Mrs. Shears blames Christopher for killing her dog, I predicted that he would try and find out who really killed the dog. I think this because he said that he really liked the dog, and that he never lies. I believe that Christopher will want to prove that he isn't lying, and he'll want the person who killed the dog to pay the consequences that he had to. I think that Christopher will eventually find the person who killed the dog.
