Can someone invite Nancy Drew to Rosewood? The mysteries (and murders) are piling up on “Pretty Little Liars,” and things are only getting more intense at Season 5 progresses.

Episode 7, “The Silence of E. Lamb,” will air on ABC Family on Tuesday at 8 p.m. EDT, and we’ve got the scoop on everything you can expect from the five Liars and their men.

“The Silence of E. Lamb” will find Aria throwing herself into her volunteer work at Radley. But as “Pretty Little Liars” fans know, she’s not adding volunteer work to her resume for college. Instead, the teen is using her inside connections to find “any answers she can about a patient of interest to the Liars.” That patient of interest? Bethany Young, the 17-year-old who was buried in Alison’s grave.

Viewers will remember that Eddie Lamb (E.Lamb), a employee at Radley, secretly dropped off a picture drawn by Bethany at Ezra’s apartment in episode 6. It seemed to depict Mrs. DiLaurentis in her rose garden with a monster reaching out for her. Ezra and the girls were confused about the drawing, and uncertain as to why Eddie wouldn’t secretly drop it off at Ezra’s apartment.

Aria will try to get to the bottom of Bethany’s connection to Mrs. DiLaurentis in episode 7, but it won’t be easy. According to the synopsis, Aria “hits a snag when she comes across an aggressive patient that may be the key to what the Liars are looking for.”

Aria won’t be the only one looking for answers in episode 7. Spencer too will be trying to get to the bottom of a couple of mysteries that are occurring in her own home. Thanks to Ezra, Spencer will become inspired to borrow some of her English teacher’s spy equipment to “keep a closer eye on the home front.”

Meanwhile, both Hanna and Emily are put in “uncomfortable positions.” For Hanna, things take a turn for the awkward when Ali and Caleb “butt heads.” Emily, on the other hand, will be seeking help from her friends after her mother invites Alison over for dinner.
