A french detective series called "Dead Beautiful" on Walter presents. I call it "Les Fous." So far in episode 1 and 2 the murderer has acted beyond bizarrely and escalated said behavior as the story went on. Despite leaving gargantuan clues behind them the cops seem flat footed. The murderer gets more and more rash and the cops are always 2 steps behind. They do come up with the motive early on, and the motive is as crazy as the killers. It does have Thierry Goddard from "Engrenages" and "A French Village" and the love life is casually french with at least three of the women pregnant by episode 2.
