The story of a man's search for the astonishing truth about his family's past. The last time Lien saw her parents was in the Hague when she was collected at the door by a stranger and taken to a city far away to be hidden from the Nazis. She was raised by her foster family as one of their own, but a falling out well after the war meant they were no longer in touch. What was her side of the story, Bart van Es - a grandson of the couple who looked after Lien - wondered? What really happened during the war, and after? So began an investigation that would consume and transform both Bart van Es's life and Lien's. Lien was now in her 80s and living in Amsterdam. Reluctantly, she agreed to meet him, and eventually they struck up a remarkable friendship.
