It has become clear for the military police captain that this very repulsive murder has been committed by a general of the Wehrmacht, and despite all the evil of the Nazi regime behind the front, a general of the German Army is nevertheless not allowed to commit sexual murders.
The captain discovers that at the time of the murder only three German generals were present in Warsaw; he then decides to find out which of them is the killer.
The only person he ever loved was a (male) soldier who died in his arms whispering the name of a woman that to General Tanz's mind was a whore.
The reader understands which of the generals is guilty, and other murders follow in his tracks, but still the investigating captain is not certain and lacks proof.
The war ends, and the final chapter is written in West Berlin, when the investigator, all three former generals, the Polish old man, and the chief of the new East German Volkspolizei gather.
