Based on a True Story

Hermine Braunsteiner is the first person to be extradited from the Unites States for Nazi war crimes. Hermine was one of a few thousand women to work as a female concentration camp guard. Prisoners nicknamed her 'the Mare' because she kicked people to death. When the camps were liberated, Hermine escaped and fled back to Vienna.

Many years later, she met Russell Ryan, an American man holidaying in Austria. They fell in love, married and moved to New York, where she lived a quiet life as an adoring suburban housewife, beloved friend and neighbour. No one, not even her husband, knew the truth of her past, until one day a New York Times journalist knocked on their door, blowing their lives apart.

The Mare tells Hermine and Russell's story for the first time in fiction. It explores how an ordinary woman could descend so quickly into evil, examining the role played by government propaganda, ideology, fear and cognitive dissonance, and asks why her husband chose to stay with her despite discovering what she had done.
