Calling all thriller fans! Paramount+ have just dropped a chilling new six-part series, and it could be your next binge-watch. The series, titled Playing Gracie Darling, follows a woman named Joni, whose childhood best friend mysteriously disappeared when they were 14. 27 years later, Joni, now a child psychologist, returns to her hometown when another girl mysteriously vanishes. The White Lotus star Morgana O'Reilly plays Joni, while Dame Harriet Walter (Downton Abbey) plays Joni's mum, Pattie. 

I'm a sucker for a small-town thriller about mysterious disappearances, and it sounds like Playing Gracie Darling has the potential to be a gripping binge-watch. Plus, Harriet Walter clearly knows a good script when she sees one, having appeared in hit shows such as Succession, Ted Lasso, Wolf Hall: The Mirror and the Light and more. Keep reading for all you need to know about the show.
