First published in 2007, it tells the story of how Ted, a boy with Asperger syndrome, and his sister Kat, solve the mystery of how their cousin, Salim, seemingly vanishes from inside a sealed capsule on the London Eye.

The next day Salim, Ted, and his older sister Kat decide to take a ride on the London Eye, bemoaning the hour-long queues.

When Aunt Gloria and Ted's mother find out about this, they become extremely angry with Kat for allowing Salim to take a ticket from a stranger.

That evening, Ted and Kat check Salim's camera and decide to have the film developed, in case it holds clues.

The family then receives a phone call from the police, saying that a boy matching Salim's description has been found dead.

However, there was a coat jacket sleeve in one of the pictures and that was how Ted worked out that the girl who left the pod was in fact, Salim.
