Monday, 24 May, 11.32 a.m. Ted and Kat watch their cousin Salim get on board the London Eye. He turns and waves and the pod rises from the ground. Monday, 24 May, 12.02 p.m. The pod lands and the doors open. People exit in all shapes and sizes – but where is Salim? Ted and his older sister Kat become sleuthing partners since the police are having no luck. Despite their prickly relationship, they overcome their differences to follow a trail of clues across London in a desperate bid to find their cousin. And ultimately it comes down to Ted, whose brain runs on its own unique operating system, to find the key to the mystery. In Spring 2009. the Unicorn Theatre adapted The London Eye Mystery for the stage. The story was adapted by Unicorn Artistic Associate Carl Miller, directed by Rosamunde Hutt and performed by the Unicorn ensemble and received a host of rave reviews.

My name is Ted Spark. I am 12 years and 281 days old. I have seven friends. Three months ago, I solved the mystery of how my cousin Salim disappeared from a pod on the London Eye. This is the story of my second mystery. This summer, I went on holiday to New York, to visit Aunt Gloria and Salim. While I was there, a painting was stolen from the Guggenheim Museum, where Aunt Gloria works. Everyone was very worried and upset. I did not see what the problem was. I do not see the point of paintings, even if they are worth £9.8 million. Perhaps that's because of my very unusual brain, which works on a different operating system to everyone else's. But then Aunt Gloria was blamed for the theft - and Aunt Gloria is family. And I realised just how important it was to find the painting, and discover who really had taken it.
