FRANCE 24 journalist Stéphanie Trouillard has specialised for years in the history of the Second World War. In 2019 she chanced upon a striking photo of a young deportee from her native Brittany. The girl was called Marie-Louise Moru; she was known as Lisette. The image shows her at Auschwitz, smiling, as if she is challenging her executioners in some way. Her show of defiance in one of the darkest places in human history inspired a quest to find out who Lisette was, what she did and what happened to her.
