Colin Kingsley is a pizza delivery boy with a twist. He's actually an aspiring detective. But in sleepy Rufflington-on-Sea, there are no cases to solve - until the Golden Spatula League come calling. The world's premier agency for 'caterer-detectives', run by children, the G.S.L. have been dazzled by Colin's freakish memory skills. To join their ranks, Colin - codenamed 'Mark Anchovy' - must fly to Rome to track down a valuable stolen painting, titled, 'Girl With A Squirrel'. The chief suspect: Big Alan Fresco, notorious art thief and pizza addict.
