'Pretty Little Liars' Season 6 News, Spoilers: The Liars Hunt for Proof to Pin Down Lesli

Things are definitely getting more interesting and intriguing as the sixth season of the hit teen TV drama series "Pretty Little Liars" continues this week with an episode that will find the Liars hunting for proof to pin down the identity of the new "A."

The previous episode titled "She's No Angel" revealed that the Rosewood girls are facing yet another new A suspect – Lesli Stone. This so happens when Aria got her hands on a photo of the girl wearing what appears to be "A's" black hoodie. Moreover, Spencer and Hanna were able to find out that Lesli was also a patient at the Radley mental institution, same as with Charles.

The challenge, which now comes in front of the girls is to actually connect the evidence to Lesli as the new A.

At Melty.com, a synopsis for the forthcoming segment titled "No Stone Unturned" was posted and it read:

"The Liars are on the hunt for proof that Lesli is A. With all signs pointing to Lesli as the tormentor in the hoodie, the PLLs are on a mission to get concrete proof before bringing their findings to the police. But as the girls ramp up their investigation, A's threats escalate. Meanwhile a friend of Emily's makes her a surprising offer, and Spencer is pressured by her family to make an important decision."

Meanwhile, a series of promo photos show the girls encroaching in a weird laboratory-like place. Their whereabouts could probably be linked to their hunt for the Lesli evidence files.
