Mary, a New England history professor researching an obscure Civil War hero, unexpectedly meets a southern gentleman lawyer, who is afflicted with alcoholism and a demanding mother. Unwisely, she is as captivated by the live man as by her dead hero.
Thane is most famous for her "Williamsburg" series of historical fiction. The books cover several generations of a single family from the American Revolutionary War up to World War II. The action moves from Williamsburg in later books to England, New York City and Richmond, Virginia.
After the Williamsburg novels, I tried to read whatever I could find of Elswyth Thane's book, but I think this is the only one I could find at our library. I don't remember it.
