Setting

The Curious Incident of the Dog in the Night-Time is set in the early 2000s, primarily in the town of Swindon, located in Wiltshire, England. The story unfolds in a contemporary setting, reflecting the technology, social norms, and cultural context of that time period.

While much of the narrative occurs within Christopher's neighborhood and home in Swindon, the story also ventures beyond these familiar confines. As Christopher's investigation progresses, he embarks on a journey that takes him to London, expanding the geographical scope of the novel. This shift in setting provides a stark contrast to the protagonist's usual routines and comfort zones.

Specific locations play crucial roles in the story, including Christopher's school, his neighbors' houses, and the local train station. The London scenes introduce new challenges for Christopher, with bustling city streets and the crowded Underground system serving as unfamiliar and overwhelming environments. These varied settings help illustrate Christopher's perspective and the difficulties he faces navigating a world that often seems chaotic and incomprehensible to him.

About the author

Mark Haddon, born in 1962 in Northampton, England, is a renowned author, illustrator, and screenwriter. He gained international acclaim with his 2003 novel The Curious Incident of the Dog in the Night-Time, which won numerous prestigious awards including the Whitbread Book of the Year and the Guardian Prize. This groundbreaking work, written from the perspective of a teenager on the autism spectrum, showcased Haddon's ability to craft compelling narratives that resonate with both adult and young readers.

With a diverse literary career spanning over three decades, Haddon has written children's books, poetry collections, and novels for adults. His works often explore complex themes and unique perspectives, as evidenced in titles such as A Spot of Bother and The Porpoise. His accomplishments in screenwriting have earned him two BAFTA awards.

A self-described “hard-line atheist” and vegetarian, Haddon resides in Oxford with his wife, Sos Eltis, an academic at Brasenose College. In recent years, Haddon has been open about his health struggles, including a heart bypass and a prolonged battle with Long Covid, which temporarily impaired his ability to read and write. Despite these challenges, he continues to contribute to literature, recently publishing a collection of short stories inspired by classical mythology. In 2023, he declined an OBE for his services to literature, citing discomfort with the award's implicit endorsement of the British Empire. This decision, along with his candid discussions about personal challenges, has further endeared him to readers and cemented his status as a thoughtful and influential figure in contemporary literature.
