The Liars are constantly on the lookout for more clues about Ali and "A”, and on Pretty Little Liars Season 4, Episode 3: "Cat's Cradle" (June 25), they might meet someone who can shed some light on the mask situation that is currently complicating their world.

In this clip from the episode, Aria, Hanna, and Emily come to a creepy house in the woods, where they discover an interesting new character  — a creepy mask maker who tells them he prefers when people make an appointment with him, but then invites them in when they show him what appears to be one of the Ali masks.

Which... whoa! Where did they get that? And what kind of secrets will he have to share?

Here's the official synopsis of the episode.  

Hanna worries that her mother is keeping a dangerous secret and is determined to protect her at all costs, which leads her to an uncomfortable meeting with Detective Holbrook. A clue in Ali's things leads the Liars to a creepy mask maker, who takes a shine to Emily and may have ties to another Rosewood resident. Spencer and Toby continue their search into a painful chapter of Toby's past and Melissa returns to Rosewood.
