The Curious Incident of the Dog in the Night-Time is a 2003 mystery novel by English writer Mark Haddon. Haddon and The Curious Incident won the Whitbread Book Awards for Best Novel and Book of the Year, the Commonwealth Writers' Prize for Best First Book, and the Guardian Children's Fiction Prize.

Haddon considered this his first novel for adults, as his previous books were for children. Unusually, his publisher also released a separate edition for the children's market, and it was successful there.

The novel is narrated in first-person by Christopher John Francis Boone, a 15-year-old boy who is described as "a mathematician with some behavioural difficulties" living in Swindon, Wiltshire. Although Christopher's condition is not stated, the book's blurb refers to Asperger syndrome. Some commentators have characterized Christopher as on the autism spectrum.

In July 2009, Haddon wrote on his blog that "The Curious Incident is not a book about Asperger's... if anything it's a novel about difference, about being an outsider, about seeing the world in a surprising and revealing way. The protagonist, being neuro-diverse shows that. The book is not specifically about any specific disorder". Haddon said that he is not an expert on the autism spectrum or Asperger's syndrome.

He chose to indicate chapters by prime numbers, rather than the conventional successive numbers, to express a different world view. Originally written in English, the book has been translated into 36 additional languages.

The book’s title is a line of Sherlock Holmes’ dialogue from the short story "The Adventure of Silver Blaze" by Sir Arthur Conan Doyle.

Plot In late 1998, Christopher John Francis Boone is a 15-year-old boy living in Swindon, England with his widowed father, Ed. One night, Christopher discovers that his neighbour Eileen Shears' dog, Wellington, has been fatally speared with a garden fork. As Christopher mourns over Wellington's body, Eileen calls the police. When a policeman grabs Christopher's arm, Christopher panics and hits him; he is subsequently arrested for assault, though he is quickly released with a caution. Christopher decides to investigate Wellington's death and chronicle his findings in a book, despite Ed's objections. During the investigation, he meets the elderly Mrs. Alexander, who informs Christopher that his late mother Judy was having an affair with Eileen's husband Roger.

Ed discovers the book and confiscates it. While searching Ed's room for the book, Christopher finds letters from Judy, dated after her supposed death. Eventually, he realizes that Judy is still alive and living in London with Roger. Finding a distressed Christopher in a catatonic state and realizing that he has discovered the letters, Ed admits to lying about Judy's death and confesses to killing Wellington in a fit of anger after an argument with Eileen. Fearing for his own safety, Christopher decides to run away and live with Judy.

After a long, event-filled journey, evading policemen and feeling overwhelmed by the trains and crowds around him, Christopher eventually finds his way to the home of Judy and Roger, much to the delight of the former and chagrin of the latter. Soon after arriving, Christopher requests to return to Swindon to take his mathematics A-level, but Judy contacts the school to postpone it. She and Roger later break up due to the latter's reluctance to accept Christopher. Judy subsequently returns to Swindon with Christopher, and the exam is reinstated.

After an argument, Judy agrees to let Ed see Christopher for brief daily visits. Christopher remains apprehensive of his father, hoping he will be imprisoned for killing Wellington. Ed gifts Christopher a puppy, whom Christopher names Sandy, and promises to gradually regain Christopher's trust. Christopher declares that he will take further exams and attend university. He completes his mathematics A-level with top grades. The book ends with Christopher optimistic about his future.

Themes

Social disability In a 2004 interview, Haddon said I have to say honestly that I did more research about the London Underground and the inside of Swindon Railway Station, where some of the novel takes place, than I did about Asperger's syndrome. I gave [Christopher] kind of 9 or 10 rules that he would live his life by, and then I didn't read any more about Asperger's because I think there is no typical person who has Asperger's syndrome, and they're as large and diverse a group of people as any other group in society. And the important thing is that I did a lot of imagining, that I did a lot of putting myself into his shoes in trying to make him come alive as a human being rather than getting him right, whatever that might mean.

Haddon states on his website that, although he had read "a handful of newspaper and magazine articles about, or by, people with Asperger's and autism" in preparation for writing the book, he knows "very little" about Asperger's syndrome and that Christopher Boone is inspired by two different people. According to Haddon, neither of these people can be labelled as having a disability. Haddon added that he "slightly regret[s]" that the term Asperger's syndrome appeared on the cover of his novel. In 2010, in an interview with The Independent, he was described as now thoroughly irritated that the word Asperger's appeared on subsequent editions of the novel, because now everyone imagines that he is an expert and he keeps getting phone calls asking him to appear at lectures.

In a critical essay on the novel, Vivienne Muller quotes some praise by experts on disability theory: In its presentation of Christopher's everyday experiences of the society in which he lives, the narrative offers a rich canvas of experiences for an ethnographic study of this particular cognitive condition, and one which places a positive spin on the syndrome. The reader in this instance acts as ethnographer, invited to see what Mark Osteen claims is a 'quality in autistic lives that is valuable in and of itself'.cited in [S.] Adams (2005) p. 1 Along similar lines, [Alex] McClimens writes that Haddon's novel is 'an ethnographic delight' and that 'Haddon's achievement is to have written a novel that turns on the central character's difference without making that difference a stigmatising characteristic.cited in [S.] Adams (2005) p. 24 Muller adds that the novel works with a strong sense of the disabled speaking subject, drawing readers into Christopher's cognitive / corporeal space through an incremental layering of his perspectives and reactions... The narrative also bristles with diagrams, maps, drawings, stories, texts that inform Christopher's lexicon for mapping meaning in a world of bewildering signs and sounds. She also admires such elements as the digressive stream-of-connectedness-and-disconnectedness way in which Christopher writes and thinks; the obsessive focus on minutiae; his musings about why animals behave the way they do; his quasi-philosophizing on death and life and the afterlife; his ambition to be an astronaut ...

In a survey of children's books which "teach about emotional life", Laura Jana wrote: On the one hand, this is a story of how an undeniably quirky teenage boy clings to order, deals with a family crisis, and tries to make sense of the world as he sees it. But it also provides profound insight into a disorder – autism – that leaves those who have it struggling to perceive even the most basic of human emotions. In so doing, The Curious Incident leaves its readers with a greater appreciation of their own ability to feel, express, and interpret emotions. This mainstream literary success made its way to the top of The New York Times bestseller list for fiction at the same time it was being touted by experts in Asperger's syndrome and autism-spectrum disorders as an unrivaled fictional depiction of the inner workings of an autistic teenage boy.

Metaphor Christopher often comments on his inability to understand or appreciate the concept of metaphors. He gives as an example a quote that he found in "a proper novel": "I am veined with iron, with silver, and with streaks of common mud. I cannot contract into the firm fist which those clench who do not depend on stimulus." Haddon told NPR journalist Terry Gross, "Funnily enough, it's actually a quote from Virginia Woolf. It's Virginia Woolf on an off day, in the middle, I think, of The Waves. An author whom I love actually, but who sometimes got a little too carried away."Gross (2003), 6:29 minutes in

Multimodality The novel is developed in various semiotic modes or resources: maps, diagrams, pictures, as well as smileys, which are not ornamental but crucial to the understanding of the plot. This means that Haddon's novel can be conceived as multimodal.

Critical response A 2006 survey in Great Britain, conducted by the BBC's literacy campaign for World Book Day, found Curious Incident to be among "the top five happy endings, as voted on by readers" in novels (the others were Pride and Prejudice, To Kill a Mockingbird, Jane Eyre and Rebecca, the last of which Curious outranked).

School Library Journal praised it as a "rich and poignant novel". The San Jose Mercury News said: "Haddon does something audacious here, and he does it superbly. He shows us the way consciousness orders the world, even when the world doesn't want to be ordered", adding that "the great achievement of this novel is that it transcends its obvious cleverness. It's more than an exercise in narrative ingenuity. Filled with humor and pain, it verges on profundity in its examination of those things—customs, habits, language, symbols, daily routines, etc.—that simultaneously unite and separate human beings." A reviewer for The Christian Century described it as "an absorbing, plausible book": "The reader becomes absorbed not only in the mystery of a murdered dog and a missing mom, but also in the mysterious world of an autistic child."
