Are you dying to know when Pretty Little Liars comes back from hiatus? Well, the show will not officially return from its hiatus until January, 2012 but our favorite little liars will be back on Wednesday, October 19 at 8 pm ET/PT for a special Halloween prequel.

Sure, the episode is a prequel, but looking back might give more insight into Allison’s relationship with other Rosewood residents — and possibly a look at who really is “A”!

Don’t forget to tune into ABC Family on October 19 for the very special episode!
