Is a man at the police station looking to take down the Pretty Little Liars?

No, not Garrett. At least, not just Garrett.

In one of the following three sneak peeks from the summer finale, we only see the mouth of a detective who is staring in at the (dirty?!?) quartet of girls, all of whom are remaining quiet and looking sullen while sitting inside the interrogation room. What has brought them here? Why are they considered guilty?

Elsewhere, Toby questions Spencer about her dad and the Liars seek out Dr. Sullivan. Watch these clips below and visit our Pretty Little Liars spoilers section for a glance into 2012.
