Two of the Mitford girls turned politically to fascism - Diana and Unity. Unity shot herself in the head when war was declared.
Diana found herself jailed during the war.
This memoir was written when Diana was in her late 60s. It's mostly written in an elegant style, with interesting parts about her involvement in the 1930s art and literary scenes. However, a strong tone of bitterness comes out about her incarceration.
Then there is of course the political stuff, about Hitler and the faultless political wisdom of her husband, Sir Oswald Mosley, whom she constantly refers to a "M". Weird!
The passages that dealt with politics I found creepy and conceited. Diana seems hell bent on not apologising for her friendship with Hitler. Nor will she discuss the mass murder of the Jews. One senses that this may be a backhander for being locked up during the war, simply because of her political sympathies. That's the best spin you can put on it. Otherwise you just assume she must still be quite sympathetic to Hitler.
I came across a biography of her at a local library. Perhaps I should investigate more.
