A biography of Wallis Simpson.
A mixture of very interesting facts (I had no idea she was still married to Mr Simpson at the time of the abdication, I always had the impression he was long gone) and wild speculation (she was flat-chested and a graphologist said her handwriting was masculine so she could have been a man with a hormonal disorder). Read with a large dose of salt handy.
Pick for the facts, so-so for the speculation.
