Major Themes of Mark Haddon's the Curious Incident of the Dog in the Night-Time

While trust is a somewhat common theme in modern novels, The Curious Incident of the Dog in the Night-Time manages to show how this idea affects people who live under atypical circumstances. Haddon tells the story through the eyes of Christopher, a fifteen-year-old autistic boy whose view of life, as well as his understanding of the world, is drastically different from that of any other teenager. Christopher is extremely sensitive, and is only comfortable in familiar surroundings and with familiar people. His daily routine consists of a series of complicated systems and he is very deeply affected when treated badly by other people. The book's two major themes come into play when Christopher must begin to face the real, adult world, where webs of lies, deception, and complex emotions reside.

This leaves Christopher to be uncertain about his father's love for him, and, most importantly, question whether or not it is safe to trust his father at all.

Ultimately, Christopher chooses not to trust his father, and his home therefore becomes an unsafe place for him to be. He decides to run away to live with his mother in London. The trip there will of course be very difficult for him to manage and will cause a great deal of strain and anxiety. Once he gets to London, Christopher thinks that he will be able to live with his mother and everything will be just fine. This doesn't happen- his mother's life is incredibly unstable, and her home isn't a good environment for Christopher to live in because he is unfamiliar with his surroundings and is uncomfortable living there.
