As Chimney Sweepers Come to Dust by Alan Bradley

 Banishment to Canada feels awful to Flavia de Luc, as if she is being punished for discovering the fate of her mother, and, being the youngest in the family. At Miss Bodycote's Female Academy, Flavia discovers that her mother was a renowned former student. The first night at the school, Flavia discovers a mumified corpse when it falls from the chimney. This begins a quest to find out why she has been sent here, how the body came to be in the chimney, and what type of training her mother actually received at the scvhool.
Flavia is a 12 year old chemistry prodogy and inveterate snoop. Miss Bodycote offers rumors of ghosts, disappearing students and a teacher who is a convicted murderer. All this is making Miss Bodycote's a much more interesting place than Flavia first assumed.
I had feared the series had ended with the previous entry, The Dead in their Vaulted Arches. I am so grateful the series continues. While each book can stand alone, the force of Flavia is best experienced by starting at the beginning and reading the entire series. I give this 5 stars!
