The last episode of season 3 was an insult to people's intelligence. They really forced their hands to create a finale that would never happened. Things such as Tom Shayes quitting in order to be approached by Toby's lawyer, that before the lawyer was cut of Toby's family. And all those killings to finish the story... And then that Joe Tobin leaving the envelope that could send him to jail in a drawer, there to anyone find it in such an easy way. Really, it was disgusting to watch so much stupidity . The last episode just ruined a season that was really good.
