The central theme of Siobhan Dowd's "The London Eye Mystery" is that the solution to our everyday problems can be found if we only take the risk of thinking outside the box and trusting our own instinct. It is also overcoming obstacles through self-sufficiency and self-trust.
The main character is Ted, a child who thinks differently that many other people, partly due to his high-functioning Autism condition, also known as Asperger's syndrome.
Along with his sister, Kat, Ted has to use his unique way of looking at situations, so that people were not quite clear on how he would solve the mystery of his cousin who dissappeared in the London Eye. Yet, the boy could consistently say "it all depends on how you look at it". This means that he trusted what he was capable of doing, regardless if his abilities were not congruent with those around him. With trust and self-confidence, he solved the mystery and showed everyone that his specific condition is not an obstacle, but another way to look at life.
This is an excellent text. Many themes and emotions are explored including; dealing with loss, trust, the bonds of a family & perseverence.
I think the way the author deals with the autistic traits of the main character is exceptional.
