"The curious incident of the dog...."; Why Christopher's findings are important?

Im writing this essay about "the curious incident ofnthe dog in the night- time" book
And as you know the hero of the novel is Christopher
And we know he accomplished 3 important things. Finding who killed the dog, being able to go to London and found his mother and wrote a book

Why are these accomplishment are important?
I need some supporting ideas to these point

Another think. if you think this topic is not good topic please i would like your opinion of another one and ill see if its in my topic list, because there is 10 topic i could choose from

Thank you so much

This is YOUR essay. Not mine. It should be clearly stating YOUR point of views, YOUR ideas and what thoughts YOU have on the topic. Why don't you do a brainstorm and jolt down what comes to mind, then we'll see where we can go from there? So, for example: finding who killed the dog. Why is the fact that he found out who killed the dog so important? What impact did it have on his life and the lives of the people around him? How did it affect the plot of the novel in general?

Personally, I don't really like this topic as a whole, but that is my opinion, not yours. What are the other options?

I'm also doing an essay about the Curious Incident of the Dog in the Night-time and could appreciate some feedback on my essay as well:

Curious Incident-Explain how Christopher changes throughout the course of the novel

Hi everyone! I am having trouble coming up with ways Christopher Boone changes throughout the novel. Could anyone help me with this? Thanks in advance!

I also need to use specific quotes/references from the novel

well, have you read the novel ?

Read the novel and go through several summaries on the internet. ( spark notes) Personally, I would read the summary first, then go through the novel.

Its an excellent novel, a very good ride.

Give me a like/ up vote if this helped. :)
