Local fans of the television show Pretty Little Liars would be forgiven for feeling a little déjà vu during select scenes. And that’s by design.

The Downingtown-raised author of the mystery novels that inspired the just-finished seventh and final season of the show intentionally wrote the Main Line into her prose.

“Readers are always trying to guess what I based the private school on, because it’s a school called Rosewood,” author Sara Shepard said in a Philadelphia Inquirer report by Colton Shaw.

“And I didn’t really base it on one school. There are so many private schools on the Main Line, and I just went to a bunch of them and looked around. I walked around Westtown (School). I walked around Malvern Prep, and I walked around Bryn Mawr, which kind of felt like its own little private school.”

Ultimately, Shepard hopes that broad inclusion helps others put themselves in her shoes and dream big.

“It’s just fun to come back to the place where you grew up and say to kids that are in school, ‘I went to this school, just like your school. I went to classes just like you did. And this is sort of what you can become if you want to take this path and you work hard and all of those things,'” she said.
