Only with Germany's takeover of Bohemia-Moravia
in March 1939, the first time that Hitler conquered a non-German people, did the Nazis' long-term policies become clear, and even then few could envision the defeat of France or the invasion of Russia.
Not a triangle but a rectangle of protagonists frame this detective plot: a young assistant detective, Morava (yes, his name sounds very much like the eastern chunk of the Bohemia-Moravia
Protectorate, and as a prey of Nazi predators he doubtless represents good in the novel); Morava's boss, Beran (as his name indicates, he is as stubborn as a ram and protects himself from the ugliness of politics); the Gestapo chief inspector, Buback (the boogey man who turns into a spy); and finally, Buback's superior, Meckerle, one of the most powerful Germans in occupied Prague.
Longerich, who takes issue with Arno Mayer and others who believe that genocide was a result of the changing war situation--the so-called "Functionalist" approach -- shows how a "blank cheque" issued before the invasion by Reinhard Heydrich (head of the Riech Security Main Office and later the brutal Reichsprotektor of Bohemia-Moravia
until his assassination in May 1942) indicates that extermination was the intention from the outset.
