This 'Mare Of Easttown' Promo Teases Shocking Details About Mare's Case

HBO

Mare of Easttown spent its first three episodes adding to Mare's list of suspects at every turn. But even with the titular detective on leave in Episode 4, the clues keep piling in, and the episode's big twist suggests fans may have been scouting off in the wrong direction this whole time. Now, the Mare of Easttown promo for Episode 5 and beyond, which teases clips from the show's upcomig second half, suggests Mare's two cases are about to get a lot more dangerous.

Warning: Spoilers for Mare of Easttown Episode 4 follow. So far, there are three cases: Katie, Erin, and Missy. Erin is dead; there is a body. Katie and Missy are missing, although Mare has believed the former to be deceased up until now.

The end of Episode 4 reveals Mare has been wrong on that count. Katie is alive and living as a prisoner in a house that looks to be not far from Easttown. Missy is now there with her, having also been kidnapped.

That's good news for Dawn, Katie's mother, who still hopes against hope her daughter will be found. But it does mean Mare has to figure out that she has two separate cases going on here. Moreover, it means that even if she solves one, there's no guarantee that will help her solve the other.

With three episodes left in the season, HBO released a "second half of the season" trailer, giving fans a look at the weeks ahead:

Although the teaser mixes footage from Episodes 5, 6, and 7, HBO has only released a synopsis for Episode 5:

In her mandated therapy, Mare opens up about her family's history with mental health; Lori tries to get to the bottom of her son's outburst at school; Mare meets with a semi-retired source to help find a possible connection to her three cases.

The footage also gives fans hope that Mare might actually find Katie and Missy alive, with hints she will eventually track down their kidnapper. The question remains, though, whether that will lead to Erin's killer as well. (Note the footage of Mare in the river where Erin's body was found.) Or, will tracking down Erin's killer lead to the missing girls?

Mare of Easttown continues on Sundays at 10 p.m. ET on HBO.
