Machines, mysteries and mayhem – this must be a case for Ollie Spark!

Ollie loves mending machines and solving mysteries. But he gets more than her bargained for when fixing Aunt Caz's van throws him into a real-life spy adventure.

He's whisked away to a mysterious city with strange plants, an unknown language and suspicious people round every corner. With the help of Gasket, his new dog best friend, he sets off on a mission to save Aunt Caz – and the city.
