The Liars are teaming up with Mona to get intel from Radley — and they’re not telling Ali. Why? Because they think Ali might be “A.” Honestly we can’t blame them. Ali’s been on our list of “A” suspects since the beginning, and her shady behavior isn’t helping. In this sneak peek from the Season 5 summer finale of Pretty Little Liars (“Taking This One to the Grave”), Spencer and Mona are taking matters into their own hands.


But will teaming up with Mona really lead them to the answers they’re searching for? After all, Mona was the original “A.” How do they know they can trust her? Perhaps that’s why it’s Spencer teaming up with Mona for Operation Break Into Radley. Meanwhile, Hanna and Caleb play lookout outside.

Unfortunately for Spencer and Mona, Officer Holbrook is onto them (or someone?) and he’s investigating Radley the same night Mona and Spencer sneak into the institution. Uh-oh. This doesn’t look good. Is this why one of the Liars is seen getting arrested in the finale promo? Or does that have something to do with the murder that goes down in the season ender?

We’ll have to wait and see! Watch the sneak peek below and hit the comments with your reactions.
