I think that Stephanie Barron‘s latest Jane Austen mystery, Jane and the Madness of Lord Byron (New York: Bantam Books, 2010), is probably her best to date. I’ve added this novel, and her next one, which is apparently to be published this year, to my list.
In “A Few Questions for Stephanie Barron” at the end of the book, Barron states that “there’s no record of . . . her [Jane Austen] having met Lord Byron[, though] she read Byron’s poetry . . . and they had acquaintances in common” (335).
