L'espionne de Berlin

The historical backdrop adds so much depth, but I'm curious whether the setting was based on real events or entirely fictional. How did the author choose Berlin for this story?

The emotional stakes felt so real, but I kept wondering how the author balanced the tension of love amidst chaos. Did the author intend to evoke a sense of bittersweet resilience?

The story offers such an intimate view of her experiences, but I'm curious whether this was a conscious choice to highlight women's stories during wartime or if it evolved during writing.
