In a sleepy French village, the body of a man shot through the head is disinterred by the roots of a fallen tree. A week later a famous art critic is viciously murdered in a nearby house. The deaths occurred more than 70 years apart. Asked by a colleague to inspect the site of the former, forensics expert Enzo Macleod quickly finds himself embroiled in the investigation of the latter. Two extraordinary narratives are set in train – one historical, unfolding in the treacherous wartime years of Occupied France; the other contemporary, set in the autumn of 2020 as France re-enters Covid lockdown.
