Hans Schiller, a German chemical engineer and SS officer who served in the Nazi death camps, fled after 1945 via Egypt to Algeria. There he trained FLN fighters in the independence war, took the name Si Mourad, married a local woman, and lived as a respected village elder near Sétif. In 1994 he was killed with his wife in an Islamist massacre of the village, and his sons in France found his papers only after his death.
The elder son, Rachel, retraces his father's path through Germany and the camp sites and comes to treat the father's crimes as his own debt. With no living perpetrator to judge, guilt that cannot be discharged turns inward. He ends his life by gassing himself, reenacting the victims' death as a form of expiation.
The novel argues that the Islamist takeover of a Paris housing estate works like the rise of Nazism. Enforcers fill the space left by an absent state, impose total codes of dress and conduct, and gain power through a population's fear and passivity. The younger brother, Malrich, learns about his father's past and reaches this conclusion: recognizing a past atrocity obliges you to name the same machinery when it forms in front of you.
A founding national story that honors anyone who fought for the cause keeps no record of who those people were before. As a result, former war criminals can be absorbed as heroes. The book reads Algeria's official independence narrative this way: it both enabled and hid a Nazi's second life, and its silence left descendants to find the truth alone.
