Gretel Fernsby is a quiet woman leading a quiet life. She doesn’t talk about her escape from Germany seventy years ago or the dark post-war years in France with her mother. Most of all, she doesn’t talk about her father, the commandant of one of the most notorious Nazi concentration camps.

But when a young family moves into the apartment below her, Gretel can’t help but befriend their little boy, Henry, though his presence brings back painful memories. One night, she witnesses a violent argument between his parents, which threatens to disturb her hard-won peace.

For the second time in her life, Gretel is given the chance to save a young boy. To do so would allay her guilt, grief and remorse, but it will also force her to reveal her true identity.

Will she make a different choice this time, whatever the cost to herself?
