Grave New World

Let the Maid Go  is the thirteenth episode of Season 4 of Pretty Little Liars. It will air in October 2013, but it isn't set at Halloween like in season 2 and season 3 due to timeline. This could possibly mean that it could be December in Rosewood. (November was established in 3x24).
