The Emmy winner goes deep on her career-defining role, as she starts thinking about what season four might look like: “I feel like you could see Mia Farrow as Elsbeth’s mother.”

Elsbeth Tascioni has wrapped her final case of the season. While the critically acclaimed CBS hit has settled into what feels like an effortless groove, propelled by its charmingly quirky eponymous hero and the best guest-cast on TV — this season alone featuring standout villainous turns from the likes of Stephen Colbert, Dianne Wiest, Amy Sedaris and Steve Buscemi — it remains a marathon for star Carrie Preston. A marathon she’s grateful for, to be sure — but as demanding a gig as she’s ever had. The True Blood and Claws alum, who won an Emmy for playing Elsbeth in her previous iteration on The Good Wife, remains dynamite in her first-ever lead TV role after decades of supporting and guest parts — as original and unusual a protagonist as you’d expect to find on broadcast network.

The season three finale saw Elsbeth’s son Teddy (Ben Levi Ross) movingly propose to his boyfriend, Roy (Hayward Leach). Kaya (Carra Patterson) returned again after being absent most of the season, undercover and overlapping with Elsbeth’s case of the week. And Patti LuPone proved to be one hell of a guest-star-note to go out on, portraying a cabaret singer holding onto her beloved New York apartment for dear life.
