The Season 1 finale of "Deception" revealed the identity of Vivian Bowers' killer (you can find out here
if you're curious). But the whys and wherefores were left for Season 2, which the show probably isn't getting. It's unfortunate that the viewers aren't going to get any explanation for the crime -- but at least they know whodunit.
