I loved this book written in a very objective way (in my opinion). He reveals a visionary Rudolph, very intelligent, probably far ahead of its time. We follow him from his childhood through drama. But through this narrative it is still very difficult to believe in the serialized novel was explained to us from the beginning. Moreover Jean Buses also speaks much of her mother, the famous Sissi. We are far from the romantic character played by Romy Schneider! Well written, clear, well-researched, this book was exciting for me.
