With the announcement that Season 6 of Only Murders in the Building will premiere on December 8, 2026, the series has officially hit a 50-episode milestone that makes it a prime candidate for a year-end binge-watch. The upcoming season, titled Only Murders in London, marks a significant departure for the mystery-comedy, moving the central trio away from their New York City home for the first time in the show’s history.
For those who have yet to dive into the world of Charles, Oliver, and Mabel, the current library of five completed seasons offers a substantial but manageable narrative arc. This “NYC era” serves as a complete chapter before the show undergoes its international transformation next year.
A New Chapter in London
The transition to London follows a major cliffhanger at the end of Season 5, which concluded its run in October 2025. While the fifth season focused on the investigation into the death of the Arconia’s long-time doorman, Lester, the finale shifted the stakes by revealing the murder of podcast rival Cinda Canning, played by Tina Fey.
Season 6 will focus on solving Canning’s murder on British soil. To support this setting shift, the series has added a high-profile roster of British talent to its cast. Newcomers for the upcoming season include Olivia Colman, David Tennant, Jodie Whittaker, Martin Freeman, and Nicola Coughlan. This casting surge suggests a “soft reboot” of the show’s atmosphere while maintaining the core chemistry between stars Steve Martin, Martin Short, and Selena Gomez.
The 50-Episode Binge Strategy
Reaching 50 episodes provides a specific advantage for viewers looking to catch up. The show’s structure—ten half-hour episodes per season—allows for a brisk pace that balances character development with the central “whodunnit” of each year.
Catching up on the first 50 episodes before the December 2026 premiere allows viewers to understand the evolving dynamics between the three leads and the long-running gags that define the series. The move to London is expected to challenge the trio’s investigative methods, which have traditionally relied on their intimate knowledge of the Arconia building and its eccentric residents.
The fifth season, which aired from September to October 2025, solidified the show’s formula while setting the stage for Canning’s death to be the catalyst for the move abroad. With over a year until the new episodes debut, the current catalog provides a complete look at the show’s New York origins before it explores a new international format.
