follow-up book to "84 Charing Cross Road" but I can't recall the title off hand.....Looks like "The Duchess of Bloomsbury Street."

Thanks Fiberbabe! That's the one. As you noted it is a bit of a tourist thing but I enjoyed it because it gave a quite satisfactory ending to the story.

Speaking of books : A friend went to England recently to visit her English husband's home land and bought a book about the American Revolution (1776) as told from English point of view. She says it is "Quite interesting!"
