Kidderly, on the face of it, is just an ordinary boy, with trouser pockets hanging out, and mischief written all over. The same can be said of his two best pals, Squelch and Twig. What so emphatically sets Kidd apart isn't at all easy to see. In appearance he's not unlike his classmates. He belongs to the Cubs. He can hold his own with other boys in PE. Or indeed with anyone of his own age. It is his hearing that makes him so extraordinarily different, for Kidd can tune in to conversations at anything up to thirty metres away, even if whispered. It's the things Kidd overhears that leads the three boys into an amazing adventure, which by turns is colourful, humorous, tense. It sees them battle it out full-blooded with a group of disreputable villains representing the worst of the adult world, whose shameful plot only our trio can thwart. Immediately Kidd schemes up a clever and cunning plan - but will it succeed, and will the grown-ups and worthies of the town ever quite understand what they owe him?
