The Brilliant Brothers founded Brilliant Minnesota, and then they disappeared. The residents of Brilliant didn't know the brothers left a puzzle needing to be solved. A chain of unexpected present-day events shakes up the Penderghast neighborhood of Brilliant: Mr. Warbler hanging between floors after stepping through a hole cut in his floor by a floornapper, then a dead body in Annabelle Avery's empty house. To the dismay of Police Chief Hank Hardy, Jezabelle Jingle and her quirky neighbors form their own sleuth group under the guise of the Penderghast Puzzle Protectors to solve the puzzle before any of them end up in pieces or--worse yet--dead. Will they be able to figure out if the same person who is causing the mysterious happenings is also Jezabelle's secret admirer, or is another mystery unfolding to complicate their investigation? Is the entire town in danger of a pernicious puzzle waiting to be solved?
