As Robbie arranges a breakfast-themed cook-off at Pans 'N Pancakes, visitors pour into Brown County for the annual maple extravaganza. Unfortunately, that includes Professor Connolly, a know-it-all academic from Boston who makes enemies everywhere he goes-and this time, bad manners prove deadly. Soon after clashing with several scientists at a maple tree panel, the professor is found dead outside a sugar shack, stabbed to death by a local restaurateur's knife. When an innocent woman gets dragged into the investigation and a biologist mysteriously disappears, Robbie drops her winning maple biscuits to search for answers. But can she help police crack the case before another victim is caught in a sticky situation with a killer?
