I found this collection a really fascinating read. My only problem with it is the editor Charlotte Mosley, she is a daughter-in-law of Diana’s. That relationship causes her to be a total Diana apologist which I could handle if she did spend so much time dissing Jessica’s political leanings. She makes it seem like being socialist until death is like endorsing Stalin, but being a fascist until death is just a quirky old lady trait. Still the letters collected speak for themselves so there is no need to read her introductions if you have reasonable level of Mitford knowledge.
