BERLIN. JANUARY 1940.

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? Compelled to dig deeper, Schenke learns of the mysterious death of a child. The cases seem unconnected, but soon chilling links begin to emerge that point to a terrifying secret.

Even in times of war, under a ruthless regime, there are places in hell no man should ever enter. And Schenke fears he may not return alive . . .
