Murder in Batz

In French, with English subtitles. In some ways this is a classic scenario, where the people of a small island town are trapped by bad weather with a killer. The detective and his assistant (who is not a member of the police) end up trapped on the island also, and the townspeople are not, at least at first, very friendly. Somebody is certainly trying to scrare them off. It turns out that both the detective and the assistant have old connections to the island. Ghosts are possibly seen, and the film gets just a bit spooky. There is another murder, and then bits of another corpse from years ago are found. The ending is quite well done, and I'm left wishing they'd made this into a series.
