The Grave's a Fine and Private Place: Flavia de Luce, Book 9 (Unabridged ed)

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.
