Pools winner and total wazzock, Dennis Sidebottom has moved next door to Ben - bringing his squeaky-clean kids with him.
The Crane Grove Crew - Ben, Barney and Jenks - soon find themselves on the Sidebottom blacklist.
Accused of being troublemakers and a bad influence, they decide to shake up the Sidebottom universe with the help of Agent Z, a meteorite and a stolen penguin.
It's Agent Z's finest hour! Mark Haddon has a sharp understanding of what makes children tick, and they will delight in the ever more daring, ever more hilarious missions of Agent Z and his three creators.
