Published 3 July 2026

From number 1 bestselling, multi-award-winning author, David Solomons, comes a laugh-out-loud new series!



When Adam and his friends accidentally reveal the secret location of ex-spy, Professor Goodspeed, they don't expect an entire world of villains to turn up on their doorstep, looking for the MI6's most famous - and dangerous - invention. Drawn into a dastardly plot, the friends must rescue the Professor and take on evil Dr Toe and all his henchmen to boot.

It's going to take buckets of bravery, a truckload of gadgets - including a flying bike, a robot-shark shield and, the deadliest of weapons . . . a glitter glue grenade - along with A LOT of luck to defeat the bad guys and stop them taking over the world.

At least the Summer holidays won't be boring . . .

The first book in a fast-paced, funny adventure series, packed with illustrations. For readers 8 years and up.
