After the drama in Biggleswade, our crime-busting duo head to York for the annual Yorkshire pudding competition and a well-earned rest ... ... well fat chance of that because they interrupt a violent robbery before they can even get to the venue. When Albert realises he's stumbled across something much bigger than a random mugging, he decides, for once, to leave the crime-solving to the locals. Fate, however, laughs at his plans, thrusting him and faithful canine companion, Rex Harrison, into the thick of things just as the first body is found. Is the coveted prize for the best Yorkshire pudding driving the competitors to the most extreme lengths? Will the team attempting to break the world record for the biggest Yorkshire pudding succeed or is someone trying to scupper their chances? One thing is for sure - one body always leads to another. There's mystery afoot, and Rex has his nose to the ground. He'll solve the crime to be sure, but will he be able to lead the humans to the criminals in time?
