Ready for another cryptic Pretty Little Liars clue? Showrunner Marlene King recently tweeted a photo that we believe is a hint about the Season 3 summer finale (Season 3, Episode 12: “The Lady Killer”).

Marlene tweeted this photo today (July 17), saying "stairway to..."

That tweet came just a few minutes after another about being on set with Shay Mitchell (Emily), and last we heard the cast and crew were still working on the finale. All of that seems to indicate that this photo is a clue about the finale.

What do you think the stairway is leading to? Tell us your theory in the comments below.
