When the Nazis looted the museums, Rose Valland was there. Behind her glasses, she took note of everything. At the risk of being shot, she spied in order to recover the looted artworks. Thanks to her, a train full of stolen art was hijacked back in 1944. A captain in General Leclerc's army, she repatriated 60,000 works of art. Her partner, Joyce Heer, remained in the shadows. In this true story that nevertheless feels like a novel, Jennifer Lesieur restores the forgotten Rose Valland to her proper place in history.
