Those wonderful Mitford gels

Right now I'm reading Mary Lovell's The Mitford Girls and not enjoying it much. I've an interest in the Mitfords - Jessica (Decca) is a hero of mine, and the rest of the brood are an object lesson in the iniquities of the aristocracy. Unfortunately, Lovell's book is essentially a long paean of praise to poor misunderstood Diana (unrepentant Fascist, friend of Goebbels, wife of Mosley etc), an elegy for Unity (personal friend of Hitler etc. etc.) and an attempt to paint Decca as a liar and fantasist because she was a Communist (who lived most of her life in rough Oakland, California, fighting for the poor and black population). Lovell, it seems, divides the world between those who hunt (good) and those who don't (rotters).
