I think that in this book called "The curious incident of the dog in the night time" by Mark Haddon, it consist of so many thing but the main thing is that Christopher (the narrator) goes on a quest/ journey and figures out a lot through out everything. In the beginning, it seems that the person that is always there for him is his dad and he tries to always stay on Christopher side no matter what the case is. In the novel there was a quote on page 16 that said "I want to see my son...why the hell is he locked up?...of course i'm bloody angry." It was explaining how Christopher was arrested for hitting a police officer but it was out of fear he didn't know how to explain it to the police officer that he was invading his person space so his way of explaining it was by hitting him. The father had came down to the precinct  because he wasn't really caring why his son was locked up he just wanted to see him and get him out the precinct. But later on in the book you see where the change happens and Christopher and Toby (his pet rat) ends up leaving to go to London but he also finds out that the dad killed wellington and that his mom was alive he finally made it to London and was able to be with her and see her even though there was some hardships that happened on the journey there.
