On the threshold of the natural and the supernatural, Agent Elizabeth "Liz" Sharrow of the Dark Forest Police Department faces a new case that tests not only her bravery, but also her perception of reality. Together with her partner Bernard Abu-Jamal and her ambitious leader Max Allen, Liz is sent to investigate a series of disturbing events in the heart of Europe, in a place called Reich der Finsternis. Along the way they discover a sect, led by the charismatic Friedrich Holzmann and his enigmatic wife, Duchess Beatrix Grünewald.
In an environment dominated by tension and mystery, Liz must face forces that go beyond understanding, involving paranormal events and abominable creatures. As she descends deeper and deeper into this dark realm of power and perversion, Liz will have to decide how far she is willing to go to put an end to a horror story that has devoured everything in its path.
Because in Reich der Finsternis, every shadow hides a secret and every whisper can be the last.
