Raphael Balthazar played by Tomer Sisley, an Israeli-French male, has become my new fascination. I am going to spoil it for you though, but this has not been indicated in the series (at all). My suspicion is and maybe you will prove me wrong, maybe they will, but I think he is the one who killed his wife. At the end of Season 2; there were too many weird things at the ending segment that suddenly made me quite curious. His friend was dead, he was a ghost talking to him and they finally told us another clue – it had to be a doctor. Red Herring of a TV show? We shall find out in Season 3; as Acorn TV has indicated there will be one. Hard to tell with foreign TV.
