I can always count on Stephanie Barron to expand my vocabulary of Regency Period slang. A "barque of frailty" is basically a promiscuous woman. It makes me snicker to think of other possibilities for the novel's title: Jane and the Tramp, Jane and the Hussy... This is the fourth Jane Austen mystery that I've read, and have equally enjoyed. It's a fun read, fast-paced, and suspenseful. But always proper, as Jane Austen would have done it.
