Usually, at the end of each show, the Mystery Theatre audience members will individually guess who the killer is, with a winner being selected from those who guessed the true murderer.
This time the audience will decide who the killer is. At the end of the evening, the audience will vote on it, via secret ballots. The top vote-getter will be declared the guilty party and the audience member with the best explanation of means and motive will win the prize. This means audiences will see one of four possible endings on any given night!
