Second-Hand
Very Good condition
Christopher is 15 and lives in Swindon with his father.
He has Asperger's Syndrome, a form of autism. He is obsessed with maths, science and Sherlock Holmes but finds it hard to understand other people.
When he discovers a dead dog on a neighbour's lawn he decides to solve the mystery and write a detective thriller about it.
As in all good detective stories, however, the more he unearths, the deeper the mystery gets - for both Christopher and the rest of his family.
