When Flavia de Luce is banished to Miss Bodycote's Female Academy in Canada, she’s soon on familiar ground when, on her first night, a mummified body is dislodged from a chimney, and she is presented with a gruesome puzzle to solve. Girls have been disappearing with alarming regularity, leading Flavia to wonder not only how and why but what exactly is the academy's true purpose? Flavia must enter a shadowy world where truth and lies seem interchangeable and no one can be trusted.

The villagers of Bishop’s Lacey are holding their collective breath as St Tancred’s tomb in the local church is about to be opened after five hundred years. Inveterate eleven-year-old sleuth Flavia de Luce is first at the scene, but the body she finds lying there is not that of a desiccated saint; it is Mr Collicutt, St Tancred's celebrated organist.

Flavia is enjoying the summer, spending her days punting along the river with her reluctant family. Languishing in boredom, she drags a slack hand in the water - and catches her fingers in the open mouth of a drowned corpse. Flavia needs to put her super-sleuthing skills to the test to investigate the murder of three gossips in the local church and to keep her sisters out of danger.

Twelve-year-old Flavia de Luce is back at Buckshaw at last, but her homecoming is overshadowed by news of her father's illness. Forbidden from visiting him in hospital, Flavia busies herself in the village, but she soon makes a macabre discovery: the corpse of a reclusive woodcarver in an empty house, except for a curiously uncurious cat. Curiosity may not kill this cat, but Flavia is energized at the prospect of a new investigation. However, what awaits Flavia will shake her to the core.

With the family finances in a parlous state, Flavia's father has rented Buckshaw to a film company for a location shooting. When a heavy snowfall cuts the village off, the actors are talked into staging a benefit performance in the parish hall. But old jealousies surface, and the leading lady is murdered. Flavia, who has been enlisted to help out behind the scenes, finds herself up to her knees in snow - and murder!
