The definite book on George III and porphyria

This book is a follow-up on Macalpine and Hunter's famous "George III and the Mad-Business". In the 70's their theory was not believed, because at that time most porphyria research had been done on the population of South Africa only. With new insights, research and techniques, including DNA research, Röhl, Warren en Hunt present very convincing additions to the diagnosis of porphyria for George III and many of his family members and some descendants.
