In the summer of 1928, Hitler aged 39, was the Nazi party leader, and he fell in love with Geli Raubal, his 20 year old niece, the daughter of his widowed half-sister, Angela Raubal. He took her everywhere, to meetings and conferences, on long walks in the mountains and to the cafés and theaters in Munich. Gossip about the party leader and his beautiful blond niece was inevitable in Munich and throughout Nazi circles in southern Germany. By 1931, some deep rift whose origins and nature have never been fully ascertained grew between them.
