Only Murders in the Building Season 4 Delivers Suspense, Laughs, and a Double Murder Mystery

The fourth season of Only Murders in the Building is shaping up to be one of its best, offering a gripping mystery (or two!) and a delightful lineup of guest stars, including Zach Galifianakis, Eugene Levy, and Kumail Nanjiani. Paul Rudd even returns, playing his former character’s eccentric stunt double, Glen.

The season kicks off with the murder of Sazz Pataki (Jane Lynch), revealed in the closing moments of Season 3. Charles (Steve Martin), Oliver (Martin Short), and Mabel (Selena Gomez) dive into the investigation, but this time, the stakes are even higher—they may be the killer’s next targets.

A standout episode, told entirely through hidden and handheld cameras, amps up the intrigue as it’s revealed the bizarre Brothers sisters have placed cameras all over the Arconium building. Combined with security footage and Howard’s camcorder, the unique storytelling adds a fresh layer of fun.

While the mystery of Sazz’s murder deepens, a second body, that of the elusive Dudenoff, is discovered. Could the residents of the building, benefiting from rent control thanks to Dudenoff’s subletting scheme, be covering up something bigger?

One theory suggests Dudenoff wasn’t murdered but died naturally, with the Westies covering it up to continue enjoying cheap rent. However, Sazz’s death complicates their plans, and the discovery of even more hidden cameras at the episode’s close leaves viewers with a chilling cliffhanger. The text message “I’M WATCHING YOU” raises the tension, as our trio scrambles to escape the building.

Despite its often comedic tone, the show handles the loss of Charles’s close friend Sazz with a delicate balance, even giving her posthumous appearances as a hallucination. The mystery surrounding her death remains intricate and unpredictable, with a standout line from Charles summing it up perfectly: “It does make sense, we just can’t make sense of it yet.”

This season not only keeps viewers on the edge of their seats but also blends humor and suspense masterfully. As Only Murders in the Building continues to unfold, the question of who killed Sazz—and whether they’ll strike again—keeps fans eagerly awaiting the next twist. How are you enjoying the season so far, and who do you think the killer might be?
