Murder Without Pity

Paris at the beginning of the second millennium: dark with riots over police killings and Far Right demagogues.
Here state criminal investigator Stanislas Cassel works at the Palace of Justice. Grandson of a French propagandist for the Nazis during their WWII Occupation and ashamed of that history, he avoids anything political. Instead, he buries himself solving small crimes, which he calls his Little Miseries.
One current dossier involves a pensioner's bizarre murder. During his pursuit for the killer/s, Cassel meets a beautiful Jewish woman, whose family the Nazis murdered. Haunted by this, she tries to alert him to the Far Right's reemergence, but to no avail. Only when tragedy strikes does he realize his blindness and understand a truth: a larger evil beyond his Little Miseries, as the Occupation portended, exist. This awareness pushes him on to get final answers to the case.
