On a lonely night, Christopher found Wellington's dog dead...
No! Wellington's dog is dead
I will investigate and discover the murderer of this dog.
The next day, Christopher began to investigate what happened yesterday.
I will write a book to record everything I find out about the murder.
Hours later, Christopher and his father are talking about the death of Wellington's dog.
Why not want me to investigate the dog
Christopher, I don't want you investigating the dog's dead.
Later, Christopher lost his book with his investigations and found some letters ...
What are all these letters addressed to me? Who wrote them?
In the evening, Christopher receives a confession from his father.
What?!
Christopher, the letters you found are from your mother, she is not dead.
I was also the one who killed Wellington's dog.
The next day, Christopher is still confused by his father's confession yesterday.
I can't stop thinking about what my father told me yesterday.
The only good thing about this is that my mom is alive and I have to find her.
