Dead of night

Berlin. January 1941. Evil cannot bring about good. After Germany's invasion of Poland, the world is holding its breath and hoping for peace. At home, the Nazi Party's hold on power is absolute. One freezing night, an SS doctor and his wife return from an evening mingling with their fellow Nazis at the concert hall. By the time the sun rises, the doctor will be lying lifeless in a pool of blood. Was it murder or suicide? Criminal Inspector Horst Schenke is told that under no circumstances should he investigate. The doctor's widow, however, is convinced her husband was the target of a hit. But why would anyone murder an apparently obscure doctor?
