Christopher is a 15 year old boy with Asperger's Syndrome that lives with his Dad. When looking out of the window he notices that Mrs Shear's dog is lying dead with a garden fork through it's chest. He runs out and picks it up. Mrs Shears sees him picking up the dog and calls the police.
Christopher decides to question people if they knew anything about Wellington's murder and to write a book about it. Christopher decides to show the book to his counsellor Siobhan, who advises him not to show it to his Dad.
Do you know who killed Wellington?
Perhaps you should be talking to your father about this
Christopher accidentally leaves his book on the dining room table and his Dad finds it and reads it. He gets angry and grabs his arm (which he doesn't like), so he retaliates and hits him. After, his Dad confiscates his book which Christopher is unhappy about.
Christopher searches his Dad's room for his book and comes across dozens of letters which were addressed to him. He reads them and he begins to realise that his Dad has lied about his Mother being dead. After acknowledging this he collapses to the ground, has a fit and vomits.
Christopher's Dad walks in and finds Christopher reading the letters. To start with he is angry but soon after he begins to cry and apologise to him. He tells him that his mother left him for Mr Shears and that he killed Wellington in vengeance.
I did it for your good, Christopher. Honestly I did. I never meant to lie.
Christopher flees to try and find his mother in London as he is afraid that his Dad may attack him like he did to Wellington. He also cannot trust him as he had lied to him. Christopher had never taken the train or tube before so he was very scared which caused pains in him stomach. Meanwhile, his pet rat Toby escapes from his pocket and runs onto the tracks. Christopher goes down to get him, whilst being unaware that the tube was approaching ,someone from the platform quickly pulls him up in time. Eventually, he finds his way to his Mother's flat.
