Query: An Intriguing Concept

This is the third of a series of not-at-all-unpleasant mysteries from Stephanie Barron, written with the conceipt that they are actually long-lost journals from the pen of Jane Austen, found in a distant American relative's belongings, and detailing Jane's family, friends, society and the mysterious events in which she keeps finding herself embroiled...In this volume, a man is murdered during a masquerade party during a Christmastide in fashionable Bath, and whispers a name as he expires--but how many women happened to be named "Maria" during Austen's time?These novels are like brief vacations to a vanished never-land of Regency England...The period detailing seems authentic; the language is Austen-like, as far as that can go, and there are pseudo-scholarly footnotes to explain unfamiliar terms and concepts. Well worth reading!
