True Detective” is back on the case.

HBO’s limited series will officially return for a third season, this time starring Oscar winner Mahershala Ali. Showrunner and creator Nic Pizzolatto is set to direct, along with Jeremy Saulnier (“Green Room,” “Blue Ruin”).

The next installment tells the story of a macabre crime in the heart of the Ozarks, and a mystery that deepens over decades and plays out in three separate time periods. Ali will play the lead role of Wayne Hays, a state police detective from Northwest Arkansas. It does not currently have an air date, nor is there a set date for the start of production.

“Nic has written truly remarkable scripts,” said Casey Bloys, HBO’s president of programming. “With his ambitious vision and Mahershala Ali and Jeremy Saulnier aboard, we are excited to embark on the next installment of True Detective.”
