Book excerpt: Winnie and Wolf is the story of the extraordinary friendship between Winifred Wagner and Adolf Hitler in the Years between the First and Second World Wars. The girl who would become Winifred Wagner was raised in an orphanage and married, at the age of eighteen, to the gay son of composer Richard Wagner. As heiress to the country's most august cultural legacy, she grows up in the Wagner family compound, surrounded by the philosophers and composers who would define western European culture in the mid-twentieth century. In 1923, the Wagners met the man who would be their hero and hope for the future: a wild-eyed Viennese opera fanatic named Adolf Hitler. Almost immediately Winnie and Wolf struck up an intimate friendship. In A. N. Wilson's most bold and ambitious novel yet, the world of the Weimar Republic comes to vivid life as the backdrop to this strange and powerful kinship.
