Death Is My Trade (French: La mort est mon métier) is a 1952 French fictionalized biographical novel by Robert Merle. The protagonist, Rudolf Lang, was closely based on the real Rudolf Höß, commandant of the concentration camp Auschwitz.
The story begins in 1913, when Lang is 13 years old. His parents give him a harsh catholic education, to which he reacts badly. His unstable father, with whom the young Lang has an awkward relationship, wants him to become a priest. At the age of fifteen, Lang starts a military career which leads in 1943 to the post of commandant of Auschwitz. At first a concentration camp, later an extermination camp, the camp, near town of Auschwitz, was the site of the “slow and clumsy creation of a death factory”. Lang works hard to achieve his mission: to kill as many Jews as possible, disposing of the bodies as efficiently as possible.
In his book, Robert Merle renamed Rudolf Höß as Rudolf Lang, his nickname after demobilization from the SS. Adolf Eichmann was renamed Wulfslang, but kept his rank of Obersturmbannführer (Lieutenant Colonel).
Robert Merle utilized Rudolf Höß’s testimonies, written in jail after his trial, as well as court records from the Nuremberg trials.
However, he came to the conclusion:
Everything Rudolf did, he did not out of viciousness, but in the name of the categorical imperative (the central tenet of Kant's moral philosophy) of duty, of loyalty to his commander, in submission to orders, out of respect for the State. In short, as a 'man of duty'; it is precisely for this behavior that he is monstrous
This, however, is an interpretation partly based on psychoanalysis and probably Merle's desire to explain how a human being could commit Höß' actions. Merle's Lang is an idealised version of Höß, stylised as a tragic persona.
While it is true that Höß tried in his process to exonerate his subordinates by declaring they did nothing but follow his orders, which he gave following in turn Heinrich Himmler's orders, there were multiple cases of corruption in Höß' time as commandant.
