***SOON TO BE A MAJOR MOTION PICTURE STARRING MARTIN FREEMAN, JONATHAN PRYCE, AND TOBY JONES***

AN INSTANT NATIONAL BESTSELLER

Amateur sleuth Flavia de Luce, along with her pestilent younger cousin, investigates the murder of a former public hangman and uncovers secrets that bring the greatest shock of her life.

Flavia de Luce has taken on the mentorship of her pestilent younger cousin Undine, whose main talent seems to be raising Flavia’s hackles, although in her best moments she shows potential for trespassing, trickery, and other assorted mayhem. 
     When local recluse and former hangman Major Greyleigh is found dead after a breakfast of poisonous mushrooms, suspicion falls on the de Luce family’s longtime cook, Mrs. Mullet. After all, wasn’t it she who’d picked the mushrooms, cooked the omelet, and served it to Greyleigh moments before his death? 
     But Flavia knows the beloved Mrs. Mullet is innocent. Together with Dogger, estate gardener and partner-in-crime, and the obnoxious Undine, Flavia sets out to find the real killer and clear Mrs. Mullet’s good name. Little does she know that following the case’s twists and turns will lead her to a most surprising discovery—one with the power to upend her entire life.
