American Horror Story writer Douglas Petrie confirmed the setting of the series' fourth season: a presumably very spooky carnival. (All you fans guessing "Hell Circus" weren't far off!) Petrie was a guest on the podcast Nerdist Writers Panel, moderated by Ben Blacker, which was recorded February 16 and released just a few days ago. Petrie was on the panel with a few other television writers, and he starts talking about the fourth season by saying, "I can't say anything."

The revelation happens around minute 33; you can listen to the whole podcast here.
