Retired teacher Esbeth Walters isn't the type to spend her golden years playing shuffleboard with the other old ladies at the senior center. She would much rather stay at home, tending her flowers and reading. But after finding Jake Marston's arm in a bed of coreopsis, Esbeth devotes her free time to sleuthing, channeling Agatha Christie detectives, much to the chagrin of Sheriff Danvers. She can't help it if she's better at solving crimes than he is. But soon, her life becomes a series of real-life murder mysteries. Between Tupperware parties, weddings, and a trip to the north woods of Maine, Esbeth and her eccentric group of pals butt heads with local law enforcement while unraveling a series of seemingly unsolvable cases.
