Dowd, Siobhan. The London Eye Mystery. David Fickling Books, 2007. ISBN 978-0375849763. Ages 9-12.

When Ted and Kat’s cousin Salim comes to visit, their mothers agree to take them for a ride on the London Eye, the largest observation wheel of its kind, so that Salim can get a one-of-a-kind view of the city. Waiting in the long line, the children are approached by a stranger who offers them a free ticket, which they give to Salim since he is the visitor. Ted and Kat watch as Salim enters one of the observation capsules and track his ride, but when the capsule returns and the other riders exit, Salim is nowhere to be found. Thus begins this captivating story as Ted and Kat attempt to solve the mystery of his disappearance, relying on Ted’s special skills and brain “that run on a different operating system” to discover their cousin’s whereabouts before it is too late.
