The Last of the Hitlers

At the end of World War II, the man Adolf Hitler called "my loathsome nephew" changed his name and disappeared. The British born William Patrick Hitler, by then settled in the USA, remained anonymous. This title tells the story of David Gardner's search for Hitler, his discovery that he was dead and had had four sons. Those four sons established a pact that, in order for Adolf Hitler's genes to die with them, none of them would have children.
