The case is closed on Only Murders in the Building season 3, but the mystery of who killed Sazz that will serve as the heart of Only Murders in the Building season 4. That's right, the critically-acclaimed comedy/mystery series starring Selena Gomez, Steve Martin and Martin Short is coming back with another season, much to the delight of its fans.

Hulu did not wait long to make the news official, announcing that Only Murders in the Building season 4 was officially renewed just hours after the season 3 finale. As the tweet sharing the news says, "let the investigation begin."

While we have to wait to find out who is going to be the next killer, we can help solve the mystery of when Only Murders in the Building season 4 is coming, who's in it and more right here. 

Only Murders in the Building season 4 release date

There is no premiere date for Only Murders in the Building season 4 at this time.

However, the cameras are rolling on the new season, so hopefully we aren't too far off for its return. For reference, each previous season premiered during the summer, though two of the three waited until August.

Only Murders in the Building season 4 plot

The Only Murders in the Building season 3 ending gave us the central mystery that the podcast trio is going to be investigating: who killed Sazz (Jane Lynch), Charles' long-time stunt double.

As we saw in the finale, Sazz was shot when she went up to Charles' apartment to get some more wine for the party. Dressed like Charles and in the darkened apartment, it seems that whoever shot Sazz meant to kill Charles. Who would that be? That'll be for Charles, Mabel and Oliver to solve.

In addition, a few of the characters had mentioned making trips to Los Angeles, and according to reports there will be a journey out west before things move back to the Arconia.

It can't be Only Murders in the Building without Selena Gomez, Steve Martin and Martin Short, as the trio of actors have proven to be a great on-screen team. A critically-acclaimed one too, as Short has been nominated for an Emmy twice for his role as Oliver and Martin once for his role as Charles. While Gomez hasn't been nominated for portraying Mabel (a legitimate snub if you ask us), she has been nominated for an Emmy for her work as one of the show's producers.

At least one other big name is also set to return, as The Hollywood Reporter has shared that Meryl Streep is set to reprise her role as Loretta Durkin, with her set to be a recurring character on the season.

Otherwise, we can make a pretty good guess that other residents of the Aroncia like Howard (Michael Cyril Creighton), Uma (Jackie Hoffman) and Jonathan (Jason Veasey) will reprise their roles in some capacity. Other recurring guest stars like Da'Vine Joy Randolph as Detective Williams, Ryan Broussard as Oliver's son Will, James Caverly as Theo and Tina Fey as Cinda Canning could pop up again as well.

As for some of season 3's other primary guest stars, that's a bit murkier. Jesse Williams' character is also in LA, but he's return has not been confirmed. However, with connections to Mabel still open, it's not outside the realm of possibility they could be back. Andrea Martin as Joy could return as Charles' jilted former fiance and a potential suspect. Plus, former recurring guest stars aren't out of the question, like Amy Ryan's Jan, who was referenced as still having a relationship with Sazz in season 3.

New cast members set to appear in Only Murders in the Building season 4 include Eva Longoria, Molly Shannon, Eugene Levy and Kumail Nanjiani, according to reports.
