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-MI6 quartermaster, Professor Goodspeed, they don't expect supervillains to turn up on their doorstep, looking for his most 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 9 years and up.
