The Devil Amongst the Lawyers, by Sharyn McCrumb. It's based on the 1935 trial of Edith Maxwell, but fictionalized enough that the author saw fit to change her name to Erma Morton. Except that it not about her at all, because nobody really cares about her story. Especially not the New York reporters descending upon Wise County, looking for the next Lindbergh baby case to sensationalize. (They've agreed Erma is a hottie, hence that portraying her as innocent is better business, facts notwithstanding.) Lots of Appalachian culture, as expected from McCrumb, but a surprising amount of Japanese culture due to one of the New Yorkers recalling his years in Japan hiding from American law.
