Mark Haddon, through the protagonist’s obsession with prime numbers, his aversion to people and yellow and brown objects, succeeds in writing from an autistic person’s point of view. The drama around his family unfolds as Christopher, the protagonist, obsessively searches for the dog’s killer and when he finds out what happened to his mother, the “skeletons” in this dysfunctional family overwhelms him. Christopher’s mother left because she couldn’t deal with the drama around him. So he travels to London to look for her.

After he visits her, she argues with her new lover and breaks up with him. So, Christopher remains the central character around his parents’ lives. The dynamics between Christopher and those around him keeps the story moving forward and grips the reader’s interest. The Curious Incident of the Dog in the Night-Time is a novel unlike others and through it we begin to appreciate an autistic person’s mindset.
