In the wake of an unthinkable family tragedy, 12-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. 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.

On a spring morning in 1951, 11-year-old chemist and aspiring detective Flavia de Luce gathers with her family at the railway station, awaiting the return of her long-lost mother, Harriet. Yet upon the train’s arrival in the English village of Bishop’s Lacey, Flavia is approached by a tall stranger who whispers a cryptic message into her ear. Moments later, he is dead, mysteriously pushed under the train by someone in the crowd. Who was this man, what did his words mean, and why were they intended for Flavia? Back home at Buckshaw, the de Luces’ crumbling estate, Flavia puts her sleuthing skills to the test.

Eleven-year-old amateur detective and ardent chemist Flavia de Luce is used to digging up clues, whether they’re found among the potions in her laboratory or between the pages of her insufferable sisters’ diaries. What she is not accustomed to is digging up bodies. Upon the 500th anniversary of St. Tancred’s death, the English hamlet of Bishop’s Lacey is busily preparing to open its patron saint’s tomb. Nobody is more excited to peek inside the crypt than Flavia, yet what she finds will halt the proceedings dead in their tracks: the body of Mr. Collicutt, the church organist, his face grotesquely and inexplicably masked.

Flavia de Luce - "part Harriet the Spy, part Violet Baudelaire from Lemony Snicket's A Series of Unfortunate Events" ( The New York Times Book Review) - takes her remarkable sleuthing prowess to the unexpectedly unsavory world of Canadian boarding schools in the captivating new mystery from New York Times best-selling author Alan Bradley.

Although it is autumn in the small English town of Bishop’s Lacey, the chapel is decked with exotic flowers. Yes, Flavia de Luce’s sister, Ophelia, is at last getting hitched, like a mule to a wagon. “A church is a wonderful place for a wedding”, muses Flavia, “surrounded as it is by the legions of the dead, whose listening bones bear silent witness to every promise made at the altar.”
