How to Teach The Curious Incident of the Dog in the Night-Time

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


Christopher Boone, a fifteen-year-old who describes himself as "a mathematician with some behavioral difficulties," becomes engaged in a murder mystery as he tries to determine who killed his neighbor's dog. His Asperger's syndrome, which causes him to view and interact with the world in a unique way, both aids and impedes his investigation. As he investigates further, despite his father's concerned disapproval, Christopher has a revelation about his mother, whom his father had said died two years ago.
