Christopher lives with his dad in Swindon. They used to be a happy family until his mum died in hospital. Christopher has autism and isn't like the other kids at his school.
One day Christopher was walking down the street and saw that Mrs Shears dog Wellington had been stabbed with a fork in her front garden. Christopher was devastated and decided to do some detective work and find out who killed Wellington.
Stop sticking your nose into other peoples business!
Christopher was very cleaver and was going to do his A level math. Some days he would just go to the library to study. But the thing that was most on his mind was...…. who killed Wellington?
To start Christophers detective work he went round asking people if they knew anything about the death of Wellington. First he bumped into an old lady who lived down his street and asked her if she knew anything about Wellington and she didn't.
Christophers dad got really angry about him doing detective work because he thought he was sticking his nose in other peoples business. His dad got so angry he was beating Christopher up which wasn't good.
During the argument, Chritophers dad ripped up all his findings and put them somewhere. Christopher went looking for his detective work and looked in some cupboards and he found a letter which was to Christopher himself. it was from his mum and was only sent a few months earlier. So Christophers mum wasn't dead after all and this was another case to solve.
