The charming town of Chilson, Michigan, is beautiful in the spring, and the bookmobile is delivering great reads far and wide on one of the first warm days of the year. But a chill sweeps through when they discover that one of their favorite patrons, the owner of Henika's Candy Emporium, has been found murdered. Although Minnie can't understand who could have had a motive to murder such a kind man, she decides that the sticky problem isn't hers to solve.

However, when rumors start flying around town and the police have no leads, Minnie decides to throw her investigative hat into the ring. The more Minnie investigates, the less certain she is that the victim's past is as wholesome as his reputation. But Minnie has plenty of experience unearthing inconvenient truths, and she and Eddie won't rest until they determine how the victim met his bitter end.
