'Pretty Little Liars' Sneak Peek: The Girls Finally Catch a Clue [VIDEO]

(ABC Family)

So far the Liars have hit a brick wall when it comes to that mysterious phone number Tippi gave them (you remember Tippi, Ali's creepy parrot that talked like her and later got birdnapped by A), but that's all about to change.

In this Tuesday's all-new episode of Pretty Little Liars, Spencer, Aria, and Emily finally get a new lead that takes them to a college in York County, PA. Will the girls find what they're looking for while exploring the halls of higher education? The episode is titled "Gamma Zeta Die!", so we're guessing they'll find more mysteries (and, you know, death) than answers. Check out a sneak peek from this week's episode below!

Pretty Little Liars airs Tuesday nights at 8/7c on ABC Family.
