Good news (and spoiler-free!) for fans of “Only Murders in the Building,” the Hulu mystery-comedy series starring Steve Martin, Martin Short and Selena Gomez as amateur sleuths/podcasters who keep stumbling over dead bodies in their fancy NYC apartment building: It’s returning for a fourth season. The third season culprits (not telling) were discovered just in time for the last-minute set-up of a death (again, not telling) to be solved for the next round of episodes. Meanwhile, the queer elements of this show become more and more pronounced, not just with regard to probable suspects and their likely victims, but with supporting characters like the scene-stealing sweater-enthusiast-and-cat-man Howard (Michael Cyril Creighton) building niches for themselves as fan favorites. The writers can get back to work building a mystery, which we’ll probably see sometime in 2024, bloody fingers crossed.
