The Grave's a Fine and Private Place. A Flavia de Luce Mystery (9)

***SOON TO BE A MAJOR MOTION PICTURE STARRING MARTIN FREEMAN, JONATHAN PRYCE, AND TOBY JONES***NATIONAL AND NEW YORK TIMES BESTSELLER"If ever there were a sleuth who's bold, brilliant, and, yes, adorable, it's Flavia de Luce." -USA TodayIn the wake of an unthinkable tragedy, twelve-year-old Flavia de Luce is struggling to fill her empty days. For a needed escape, Dogger, the loyal family servant, suggests a boating trip for Flavia and her two older sisters.
As their punt drifts past the church where a notorious vicar had recently dispatched three of his female parishioners by spiking their communion wine with cyanide, Flavia, an expert chemist with a passion for poisons, is ecstatic. Suddenly something grazes her fingers as she dangles them in the water. She clamps down on the object, imagining herself Ernest Hemingway battling a marlin, and pulls up what she expects will be a giant fish.
But in Flavia's grip is something far better: a human head, attached to a human body. If anything could take Flavia's mind off sorrow, it is solving a murder-although one that may lead the young sleuth to an early grave.
