Mark Haddon's The Curious Incident Of The Dog In The Night-Time

In Mark Haddon's The Curious Incident of the Dog in the Night-Time, Christopher's quest to find Wellington the dog's killer leads to more discoveries than he anticipated. He has to learn how to be more independent and faces lies and betrayal. Christopher's choice to solve Wellington's murder leads to his evolution as he must mature and evolve when someone he trusted lies to him and he decides he must leave his home.

He tells her why he came and she lets him stay. Eventually, a policeman shows up to the flat, talks to Christopher's mother and they decide that Christopher could stay with his mother. After a few days of Christopher living there, his mom agrees to take him to Swindon (without Mr. Shears, who she had fought with and left) so he could take his math A level exam. The two of them stay at Christopher's father's place while Christopher takes his exam, making Christopher uncomfortable, and during that time, Mr. Shears drives by and drops of some of his mother's belongings. Once Christopher finishes his A levels and his mother gets a job, they move into a big house in Swindon together. This journey changes Christopher because not only must he face traveling by himself and maturing, but he must also try to trust his father again after getting betrayed and lied to, which he eventually
