I do not know this writer, apart from the fact that he was the son of ... and perhaps because of that, I was not tried by reading it. What a mistake! This man has a real talent. I read the book in one sitting, each chapter being more confusing and breathless than others. I love these investigations that go to the Middle Ages or mele is history and enigma.
