The Mysteries of Laura

Having earned her stripes tangling with "A" as mad Mona on Pretty Little Liars, Janel Parrish might next find herself worrying about the letter of the law with a guest spot on tonight's Mysteries of Laura (NBC, 8/7c). In this exclusive clip from the episode, Parrish's wealthy party girl Jillian is interrogated by Laura (Debra Messing) about her connection to a murdered club kid responsible for a string of jewelry-store robberies.

She seems innocent enough, but anyone who's seen Parrish in action on PLL can testify that the girl knows how to sell a story with the best of them. And the worst of them (yes, Ali, we mean you).

Tell us in the comments what you think of the Rosewood Terror's trip to Mysteries.
