Must You Go? By Lady Antonia Fraser. I just started it last night after I took it from the library (which incidentally was closing early because of "weather"... I mean it's like Grandma Betty in high school - in your best Harvey Fierstein: "Honey, don't go out there... there's gonna be weather.")
Anyway, it's very good, very dishy. Sort of like the Liz and Dick Burton of England (except they're both English too) but not as glamorous, more literary, uglier and more esoteric references - if she compares him to Richard III once more or calls him Pinteresque. I mean, no shit he's Pinteresque. He's Harold Pinter Lady!
