When popular TV baking contest and national institution ‘The Best of British Baking Roadshow’ rolls into town and sets up camp in the grounds of Boskern House, a historic stately home near Penstowan, former police officer Jodie ‘Nosey’ Parker finds herself competing to represent Cornwall in the grand final.

But with a fellow contestant who will stop at nothing to win and a drag queen host with secrets of their own, Jodie discovers that the roadshow doesn’t just have the ingredients for the perfect showstopper cake, but also for the perfect murder… And when a body is found in the grounds of the house, Jodie is drawn into another high-stakes case along with local DCI Nathan Withers. Can Jodie expose the culprit? Or will the murderer become the real showstopper?
