Everyone's favourite underdogs are back! Can they land work on a film set - and foil a cat burglar - with their unusual and motley skills?School is out for the summer, and the Dunderheads are finally rid of the awful Miss Breakbone. Or so they thought! Teen star Ashley Throbb-Hart is shooting a film nearby, and who should show up as an extra but their formidable former teacher!

She's not the only Breakbone on the scene, either; after a string of burglaries strikes town, Miss Breakbone steers her barrel-chested brother, Inspector Breakbone, towards those meddling, good-for-nothing Dunderheads. And when Spider ends up in the wrong place at the wrong time, the inspector has all the evidence he needs to lock him up.

Can Einstein, Wheels, Nails, Spitball, Google-Eyes, Clips, Junkyard and Hollywood combine their talents to catch the real criminal before they join their friend behind bars?

A delightfully quirky sequel to the best-selling The Dunderheads (9781406326048).
