Online Scavenger Hunt Begins for ABC Family's New Mystery Series, Pretty Little Liars

To help promote its new mystery series, Pretty Little Liars, ABC Family has begun an online scavenger hunt in which one can win a special VIP screening of the January premiere of the series for up to 10 people.

Here's the clue for the first mission: "I've put a photo of some of my work on the internet. But where? Write down the word I wrote on the mirror when the lights are Flickring. -A" (OK, we're lost and don't get it. Do you?)

Part of the mystery here is, Who is "A"? The series is set in Rosewood, a perfect little town. So quiet and pristine, you'd never guess it holds so many secrets. Some of the ugliest ones belong to the prettiest girls in town -- Aria, Spencer, Hanna and Emily, four estranged friends whose darkest secrets are about to unravel.

One year ago, Alison, the Queen Bee of their group, disappeared and the girls swore they'd never tell what really happened that night. They thought their secrets would bond them together, but just the opposite is true. Then again, who's to say what the truth is in Rosewood. It seems everyone in town is lying about something.

Now, as the mystery surrounding Alison's disappearance resurfaces, the girls begin getting messages from "A," saying –- and threatening –- things only Alison would know. But it couldn't be Alison. Could it? Whoever it is, they seem to know all the girls' secrets, and seem to be watching their every move. The girls are friends again, but will they be there for each other if their dark secrets come to light?

Pretty Little Liars premieres Monday, January 3rd, 2011, at 8 PM (ET/PT) on ABC Family.
