That’s the Mitford sisters. I put ‘mitford sisters’ into the search on amazon books, and it pulled up several titles; are you thinking of The Mitfords: Letters Between Six Sisters by Charlotte Mosley,The Sisters: The Saga of the Mitford Family by Mary S. Lovell , or some other title?Unity was the nazi sympathizer. I haven’t read any of the books on them, but maybe some FReeper who has will recognize the titles and post a review.
It was “The Mitfords: Letters Between Six Sisters” by Charlotte Mosley. Saw it at the bookstore, but $39.95 was a bit too rich to buy without a reccommendation. I see it’s cheaper on Amazon. Unfortunately, the Amazon search also led me to a collection of Noel Coward’s letters which shall have to go on the buy list, so any savings will be a wash.
