From the moment that Jim and his best friend Charlie bug the staffroom and overhear two of their teachers speaking to each other in a secret language, they know theres an adventure on its way. But what does spudvetch mean, and why do Mr Kidds eyes flicker with fluorescent blue light when Charlie says it to him? Perhaps Kidd and Pearce are bank robbers talking in code. Perhaps theyre spies. Perhaps theyre aliens. Whatever they are, Jimbo and Charlie are determined to find out. There really is an adventure on its way. A nuclear-powered, one hundred-ton adventure with reclining seats and a buffet car. And as it gathers speed and begins to spin out of control, it can only end in one way . . . with a BOOM!Note: This book was first published in 1992 under the title Gridzbi Spudvetch! It has now been completely re-written (Mark has changed pretty much every sentence one way or another) and given a new title that is much easier to pronounce!
