Paris, France: dark with fog, riots over police killings, and Far Right demagogues.
Here state criminal investigator, Stanislas Cassel, grandson of a French propagandist for the Nazis during World War II, works at the Palace of Justice. Ashamed of his family's notoriety, he avoids anything political. Instead he absorbs himself solving small crimes. Little does he suspect the shock awaiting him when he looks into the bizarre murder of a pensioner, who seemed to have lived an uneventful life. A thriller for today's turbulent times!
