Tell no one

I rented this french DVD, which was directed by Guillaume Canet, on Lovefilm. It is a pretty tense thriller that stars Francois Cluzet as a paediatrician whose wife is mysteriously murdered and then eight years later he is anonymously sent a video clip via the Internet that seems to show her as being alive. In the meantime he is implicated in a connected double murder hunt, and has various scrapes with the police and others. All in all a very gripping but not too gruesome film that had me guessing throughout.
