Fans of the young adult sudser/thriller can visit the Suspect Tracker at ABCFamily.com/TheBetrayal to survey the list of 12 candidates, one of whom will be unveiled as a very bad egg. By clicking on each photo, users can read comments/theories from fellow viewers, and then cast their vote for the likely culprit.

Who do you think has been acting as a covert cohort to “A”? As of Tuesday afternoon, Paige was leading the Suspect Tracker vote, followed by (Oh, nos!) Ezra. Toby and Melissa were tied for third, while Lucas, Caleb and Aria — yep, a Liar herself — rounded out the Top 7.

Bringing up the rear as long shots are Spencer, Aria’s dad Byron, Emily and Hanna, while Hannah’s mom Ashley had yet to elicit a lick of suspicion. (C’mon, folks — it’s Melrose‘s Sydney! Cast a wary eye!)
