Only Murders in the Building Season 3 plot: What will happen next season?

The official plot for the first episode of the new season is as thus: “After Ben Glenroy’s collapse on stage, Charles, Oliver and Mabel piece together the show’s first days with a suspicious cast and crew to determine if foul play was involved.”

It’s likely that we won’t get much information about the plot, since the show is of the mystery genre. But there are things that we can expect.

The last episode ended on a cliff-hanger, with Ben Glenroy (Paul Rudd) dying onstage in front of all our main cast. Therefore, we can imagine that the third season will cover what led to this series of events, as well as the creation of the golden trio’s podcast, which discusses each murder. Not only that, but Glenroy and Charles clearly had a vendetta with one another, so that will likely play into everything.

Although, we can perhaps expect this season to dive into Oliver, as the previous two seasons had Mabel and Charles’ past play into the grander mystery. And since this third season murder happens at one of Oliver’s shows, this season could be focusing more on him.

This was even suggested by showrunner John Hoffman. In an interview with Slash Film, Hoffman stated that for Season 3 they were eager to lean “towards Oliver Putnam and the world of theatrics, and his wishes and dreams to regain a reputation after his debacle with Splash!”

And it seems like fans are enjoying the season’s new, twisty mystery as Season 3 is currently sitting at a 99% critic’s score and 89% audience score on Rotten Tomatoes.
