Pretty Little Liars Season 4 Behind-the-Scenes: Sneak Peek Set Pics (PHOTOS)

We've been losing sleep over all of the twisted storylines on Pretty Little Liars Season 3 — ;Is Spencer really part of the "A" team? Who's the girl in the red coat? Is Jason dead? — but luckily, we can finally focus our attention on something else: Season 4 sneak peeks!

Click through the gallery to see PLL writer Joseph Dougherty and showrunner Marlene King's behind-the-scenes pics from the set of Season 4. Between creepy shots from Radley and an Alfred Hitchcock-looking setting, we're totally psyched (and spooked!) for what's to come.

As for what we're going to find out in the upcoming season? Marlene tweeted that Season 4 is going to be “killer,” and that we'll find out who pushed Ian off of the bell tower in Season 1 and more. Bring it on!

Catch the Season 3 finale on Tuesday, March 19, 2013 at 8 p.m. ET/PT on ABC Family.
