The five staff members of R&P Laboratories have an unfortunate habit of getting involved in criminal investigations when they should be pursuing scientific activities. In these four stories, Rob, Phil, Ellis, Virginia and Mitch tackle four mysteries involving a possibly poisoned pie, an unusual Christmas present, a harmonica-playing uncle and a stolen Volkswagen Beetle.
These four stories — 'Halfbaked', 'Potluck', 'Livewire' and 'Scoreboard' — were previously published under their individual titles.
