Lucy Honeychurch visits Italy with her well-starched cousin, Charlotte. (I have a copy of the Baedeker guides they probably would have used from the early 1900s, they're fascinating books in themselves.) Their lives are changed by the people they meet, the Emersons, who are kind enough to swap hotel rooms, to give them a room with a view. Lucy is thrown into chaos on her return to England...

This was also a wonderful movie.
