It was seven minutes past midnight when Christopher found him and wellington was dead on the ground it had seemed he was stabbed by a garden fork .
When Mrs shears came out she thought that Christopher killed wellington therefore she called the police but when the police man tried to pick up Christopher he hit him so they took him to prison to be questioned about the dog and hitting the police officer but was let off with a warning this is when he decided he was going to write a book about trying to find out who killed Wellington .
Christopher then decided to knock on the neighbors doors to ask about Wellington and to find anything out about the crime so he could find out who killed Wellington but when his Father found out he got cross and said he wasn't allowed to do any more detective work and he wasn't allowed to ask the neighbors or even talk about Wellington.
One day when Christopher was on his way to school he saw 5 red cars in a row which meant that it was a super good day so after school when Christopher went in the shop he bumped into Mrs Alexander who told him that his Mother and Mr Shears were having an affair so he wrote it down in his book. Father found it he got really cross and grabbed Christopher so Christopher hit him and then his dad hid his book so he could no longer write in it.
Christopher searched the whole house to find where his dad had hidden it and finally he searched in his Father's room and he found his book in an old t- shirt box in his Father's wardrobe on top of lots of letters addressed to him. He took the letters and opened them and he saw that they were sent from his mother eighteen months after she died and when his dad found him reading them he confessed to every thing.
He confessed to how he lied about his mother being dead and that he thought it would be easier to say also he admitted he was the one who killed Wellington this made Christopher feel unsafe to live with his Father anymore as he might kill him too therefore his only option is to go to his mother in London so he packs his food and Toby his rat and heads for the train station to go to London.
