HBO is becoming a Streep family business. Weeks after the network confirmed Meryl Streep will make an Emmy-gobbling return for Big Little Lies Season 2, True Detective has now added her daughter Mamie Gummer to the Season 3 ranks for a likely 2019 premiere.

The Hollywood Reporter announced that Gummer will play a central role in one of the season’s leading mysteries, described as “Lucy Purcell, a young mother of two at the center of a tragic crime.” It’s unclear if that character is connected to the one played by The Girlfriend Experience star Carmen Ejogo – said to be that of a schoolteacher connected to two missing children – or Scoot McNairy’s role as Tom, “a father who suffers a terrible loss that ties his fate to that of two state police detectives over 10 years.” The third season is said to chronicle “a macabre crime in the heart of the Ozarks and a mystery that deepens over decades and plays out in three separate time periods.”

As for the Streep-HBO connection, Meryl Streep had previously won an Emmy for her role in Angels in America at least fifteen years prior to joining Big Little Lies Season 2. Streep’s other daughter, Grace Gummer, also made extended appearances on Aaron Sorkin and HBO’s The Newsroom.

Elsewhere of True Detective Season 3, Moonlight Oscar-winner Mahershala Ali will play Northwest Arkansas state police detective Wayne Hays, alongside Stephen Dorff as his partner, Roland West. Series creator Nic Pizzolatto will serve as Season 3’s primary writer, aided by Deadwood boss David Milch, who will direct the fourth episode. Pizzolatto will also showrun and direct with Jeremy Saulnier, while additional executive producers include Scott Stephens, Woody Harrelson, Matthew McConaughey and original director Cary Fukunaga.

The Hollywood Reporter also corroborates True Detective Season 3’s likely 2019 premiere, so stay tuned for the latest.
