The Sweetness at the Bottom of the Pie is a mystery by Alan Bradley published in 2009. Set in the English countryside in 1950, it features Flavia de Luce, an 11-year-old amateur sleuth who pulls herself away from her beloved chemistry lab in order to clear her father in a murder investigation. Bradley, a first-time novelist, wrote the book after winning the 2007 Debut Dagger Award and selling the publishing rights in three countries, based on the first chapter and a synopsis. Well received by critics as an old-fashioned mystery featuring an unforgettable protagonist, the novel has won multiple awards and is the first in a proposed 10-book series.
