Enzo Macleod returns to solve two murders that are seventy years apart.
In a sleepy French village, the roots of an uprooted tree unearth the body of a man with a bullet in his head. A week later, a famous art critic is murdered in cold blood in a nearby house. However, the two murders are more than seventy years apart.
Forensic expert Enzo Macleod is asked to examine the first murder scene, and before he knows it, he's also helping with the investigation of the second case. Two stories begin to unfold—one from the past, from the years of the wartime occupation of France, when officials of the Third Reich coveted the pinnacle of European art, the Mona Lisa. The second story takes place in the present, in the autumn of 2020, as France is in the grip of the second wave of the COVID pandemic. Is it possible that the two cases are somehow connected? And how far does the chain of events stretch, which began the moment the director of the National Museum in Paris, Jacques Jaujard, decided to save the masterpieces from the Louvre from Nazi looting?
