Mark Haddon’s The Curious Incident of the Dog in the Night-Time is told from the perspective of Christopher, a teenager with “behavioral difficulties.” Although Haddon does not specifically name Christopher’s condition, it is widely understood that he has Asperger’s syndrome. Students should learn about this autism spectrum disorder and its common characteristics, but be aware that Christopher’s behaviors are not indicative of how all people with Asperger’s act.

With this background, students can discuss the communication obstacles that Christopher faces regularly. They should examine how people interact with him and whether they take his differences into account. This can open a broader discussion about mental illness or difference, including how it is perceived by society, how it can be used to define people, how it affects family members, and how people can live full and satisfying lives despite difficulties they face.

Haddon also includes graphics and illustrations, such as diagrams, smiley faces, and graphs, in his novel. These elements will prompt class discussion on what these images convey and how they allow readers to understand Christopher in ways that words do not.
