The Arconia’s Next Chapter: 7 Shocking Secrets And Everything We Know About Only Murders In The Building Season 6
The cozy crime-solving trio of Charles, Oliver, and Mabel has done it again. As of December 2025, the dust has settled on the highly-anticipated fifth season of Only Murders in the Building (OMITB), which once again captivated audiences with its signature blend of comedy, mystery, and celebrity cameos. The good news for fans is that the Arconia's murder spree is far from over, as Hulu officially announced the renewal for Season 6, ensuring the podcast—and the drama—will continue well into 2026. This article breaks down the biggest takeaways from the recent season, the shocking finale cliffhanger, and the confirmed details for the next chapter.
The success of the show, which has consistently dominated the streaming charts, lies in the electric chemistry between its three lead stars, who bring a multi-generational appeal to the true crime genre. With the Season 5 finale leaving a fresh body on the floor—a tradition for the Arconia residents—the stage is perfectly set for a brand new investigation when the show returns.
The Iconic Trio: Steve Martin, Martin Short, and Selena Gomez Profiles

The Shocking Aftermath of Season 5: Who Was the Doorman's Killer?
The fifth season, which premiered on September 9, 2025, brought the action back to the familiar, yet deadly, confines of the Arconia after the brief Los Angeles detour in Season 4. The central mystery revolved around the murder of the building's long-serving doorman, Lester, whose death was initially dismissed as a natural cause until the trio's podcast instincts kicked in.
The Season 5 investigation saw Charles, Oliver, and Mabel navigating new personal challenges while trying to solve the doorman's murder. Mabel Mora, in particular, was dealing with the fallout of her recent art show success and the pressure of a high-profile relationship, adding new layers to her character arc. Oliver Putnam's theatrical ambitions, as always, became intertwined with the murder investigation, while Charles-Haden Savage struggled with maintaining his sobriety and his relationship with Joy.
The finale delivered a satisfying, yet complex, resolution. The killer was revealed to be a seemingly minor character—a relative of a former Arconia resident who had a long-standing, petty grudge against Lester for a decades-old eviction. This twist underscored the show's theme that even the smallest details and most minor characters can hide the darkest secrets. The Season 5 ending also saw the return of several fan-favorite entities, including Loretta Durkin (Meryl Streep), who was nominated for a Critics Choice Award for her performance in December 2025.
Season 6 Renewal and the Next Arconia Victim: What’s Confirmed for 2026?
The most exciting news for fans in late 2025 is the official greenlight for Season 6 of Only Murders in the Building. Hulu announced the renewal on October 28, 2025, just as the Season 5 finale aired, confirming that the show’s popularity remains sky-high.
The show’s creators have already teased that the next season will dive deeper into the history of the Arconia building itself, suggesting that the new murder may be linked to a secret from the past. The Season 5 finale’s traditional cliffhanger revealed the next victim: a new, wealthy investor who had just purchased the building's penthouse, threatening to turn the Arconia into luxury condos. This character, whose name is yet to be fully revealed, was found dead in the freshly renovated penthouse, seemingly from a fall, but with a mysterious, antique theater prop nearby. This instantly connects the new case to Oliver’s world of Broadway and Charles’ acting history.
7 Key Entities and Plot Points to Anticipate in Season 6:
- The Penthouse Murder: The investigation will center on the new, high-profile victim and the immediate pool of suspects who stood to lose the most from the Arconia's gentrification.
- The Return to the Arconia: After a brief shift in focus during Season 4, Season 5 and the upcoming Season 6 firmly establish the Arconia building as the main character and setting.
- Mabel Mora's Career: Mabel's success as an artist and her new wealth will complicate her involvement with the true crime podcast, adding a new dynamic to her relationship with Charles and Oliver.
- Oliver Putnam's New Play: The antique theater prop found at the crime scene suggests Oliver's next theatrical endeavor might be more closely tied to the murder than he'd like, potentially making him a prime suspect again.
- New Guest Stars: While no names are confirmed for Season 6 yet, the show’s reputation for A-list cameos (Eva Longoria, Eugene Levy, Zach Galifianakis, etc., in Season 4) ensures a fresh batch of celebrity suspects will join the cast.
- Charles' Family Secrets: The series often delves into the past of its main characters. Season 6 is rumored to explore a new, shocking revelation about Charles Haden-Savage's estranged family.
- The Podcast's Future: The success of the "Only Murders in the Building" podcast itself is a major plot point. Season 6 will likely explore the ethical dilemmas and fame that come with being a successful true crime podcaster.
The anticipation for Season 6, which is expected to premiere in late 2026, is already building. With the trio back in the Arconia and a new, high-stakes murder to solve, the next season promises to be the most complex and star-studded yet, solidifying Only Murders in the Building's status as a must-watch comedy-mystery series.
