Last week, Hanna went to Mona for help constructing a big lie, because no one knows how to spin a tail like the original "A" ... at least that we know of. That said, Pretty Little Liars is overflowing with characters keeping secrets and telling lies, and for now, we have no way of knowing who the biggest liar in all of Rosewood is. Will we find out soon?

According to the following Twitter exchange between a fan and director Norman Buckley, yes, yes we will:

Based on that tweet, it sounds like we'll be finding out about a big liar come the Season 4 summer finale (Season 4, Episode 12). Could that be connected to the reveal of Red Coat? It seems like the head of the "A" team would be the biggest liar around, but given that recent spoilers suggest we won't see Red Coat fully revealed until the Halloween episode, the biggest liar in Rosewood might be someone else...

Whatever the case, we can't wait to find out who Norman is talking about!
