When a man uncovers the facts of his parents’ murder, he finds worse - his German father was a Nazi scientist. Told through the diaries of two brothers - Rachel who records the truth and Malrich, younger and more streetwise, seeking to understand how these revelations fit with his life on a French estate where Islamic extremism reigns – this is a sad, compelling read which epitomises the idea of the sins of the father being visited on the sons.
