The sweetness at the bottom of the pie

Eleven-year-old Flavia de Luce is an aspiring chemist with a passion for poison. In the summer of 1950, a series of inexplicable events strikes Buckshaw, the decaying English mansion that her family calls home. A dead bird is found on the doorstep, a postage stamp pinned to its beak. Later, Flavia finds a man dying in the cucumber patch. For Flavia, who is both appalled and delighted, life begins in earnest when murder comes to Buckshaw. (Bestseller)
