The third Mitford daughter, Lady Diana Mosley (1910-2003), discredited herself to become known as 'that woman' who left her husband for Oswald Mosley, head of the British Fascist Party, and for making a close friend of Hitler, remaining unrepentant and defending him until her death.
Descriptions of conditions in wartime prisons where Mosley was interned and the rise of political extremism in the 1930s add historical value but ultimately nothing redeems Mosley in her choice of allegiance and denial of the Holocaust. At her request, the book was not published until after her death in 2003.
