In a finale packed with twists, ‘Only Murders in the Building’ Season 5 unmasked Mayor Beau Tillman’s intricate role in Lester’s death, only to immediately plunge the podcasting trio into a new, international mystery as Cinda Canning becomes the latest victim, setting up a captivating Season 6 in London.
The fifth season of Hulu’s acclaimed mystery-comedy, ‘Only Murders in the Building,’ delivered a finale on October 28, 2025, that not only resolved the season’s central murder but also orchestrated a stunning twist, completely reshaping the series’ landscape for its upcoming sixth season. Fans were left reeling by the definitive revelation of Lester’s killer and an unexpected cliffhanger that sends Charles, Oliver, and Mabel on an international adventure.
Since its premiere, ‘Only Murders in the Building’ has captivated audiences with its unique blend of humor, heart, and intricate whodunit plots, centered around three unlikely friends who launch a true crime podcast to solve murders in their upscale New York City apartment building, the Arconia. Each season builds to a thrilling conclusion, and Season 5 proved no exception, delivering one of the show’s most complex and surprising resolutions yet.
Unmasking Lester’s Killer: Mayor Beau Tillman’s Tangled Web
The mystery of Lester’s (Teddy Coluca) death, which kicked off Season 5 with his body found in the Arconia’s fountain, finally reached its dramatic conclusion. The finale unveiled Mayor Beau Tillman (Keegan-Michael Key) as the culprit, a revelation deeply embedded in a web of political corruption, illicit affairs, and accidental deaths. According to Entertainment Weekly, Tillman’s confession provided the full, shocking narrative.
A Chain of Tragic Events
The night of Lester’s death was a cascade of unfortunate events:
- Nicky Caccimelio’s death was accidental, occurring in the casino room where he confronted Mayor Tillman about an affair with his wife, Sofia Caccimelio (Téa Leoni).
- Nicky, enraged, sliced off Tillman’s pointer finger with a cleaver (the very one Oliver later found).
- During the chaos, Lester intervened, stabbing Nicky in the back. Nicky then collapsed onto Lester, accidentally driving the cleaver into his own chest.
- Fearing exposure, Tillman pursued Lester, demanding the missing finger and silence regarding his corrupt past.
- Lester, refusing intimidation, attempted to text his wife, “It’s Beau Tillman,” but autocorrect famously changed it to “It’s Beautiful.”
- In a final desperate act in the Arconia courtyard fountain, Lester activated his bird whistle, hoping to turn on a hidden camera. However, Tillman caught up and pushed Lester against the fountain, killing him.
Justice Served and the Arconia Saved
Following Tillman’s confession, the mayor attempted to trap Charles, Oliver, and Mabel, planning to bury them during the Arconia’s demolition for a casino. However, the quick-thinking podcasters escaped, exposing Tillman’s guilt to reporters using a secret recorder hidden in a roulette table. Tillman and his billionaire co-conspirators—Camila White (Renée Zellweger), Sebastian “Bash” Steed (Christoph Waltz), and Jay Pflug (Logan Lerman)—were promptly arrested.
The billionaires had actively covered up Nicky’s death, even storing his body in a cryochamber for a week, which explained the mysterious freezer burn on his ear. Ultimately, Jay’s full confession to the police dismantled Camila’s casino plans, ensuring the Arconia’s preservation, much to the relief of its residents.
A Shocking Twist and a “Big Shift” to London for Season 6
In true ‘Only Murders in the Building’ fashion, the resolution of one murder immediately paved the way for another. A three-month time jump revealed a new murder outside the Arconia, setting the stage for Season 6. This time, the victim is none other than true crime podcasting rival, Cinda Canning (Tina Fey).
The scene cuts to Charles, Oliver, and Mabel listening to Cinda’s latest podcast, “The Girl with the Curls,” where she describes investigating a red-haired woman accused of killing a royal descendant in London. Shortly after, a red-haired woman collapses, bleeding, just outside the Arconia gates. The trio and Howard debate whether the death “counts” as “in the building” until her hand slips through the gate, confirming it. Upon turning her over, they discover it is Cinda Canning herself.
Showrunner and executive producer John Hoffman discussed this pivotal decision with TheWrap, describing the shift to London for Season 6 as a “big shift” and a “great jolt of energy.” He noted that bringing the trio to the birthplace of the cozy murder mystery genre, influenced by figures like Agatha Christie and Sir Arthur Conan Doyle, offers a unique opportunity for cultural clash and a refreshed dynamic. “It felt like a good opportunity to really do a big shift for the trio and make a real move that feels fresh and different for the show,” Hoffman explained.
Fans have eagerly awaited an international adventure for the podcasting team, and Cinda’s unexpected demise provides the perfect catalyst. The mystery surrounding “The Girl with the Curls” and Cinda’s apparent involvement promises a new kind of puzzle for Charles, Oliver, and Mabel to unravel across the pond.
The Future of ‘Only Murders in the Building’
The finale also served as an emotional farewell for Teddy Coluca, who portrayed Lester. John Hoffman shared the heartfelt moments during Coluca’s last day of filming, highlighting the actor’s beloved presence on set. While the show is known for its revolving door of celebrity guest stars and recurring characters, the departure of Lester marks a significant moment.
Looking ahead, Hoffman expressed enthusiasm for the show’s future beyond Season 6, citing the expansive nature of its themes and characters. “As long as they’ll have us, I feel like these characters are really now in our bones,” he told TheWrap, suggesting that the creative team continues to find fresh narratives and opportunities to push the beloved trio forward.
Fans can revisit all the mysteries, including the latest Season 5 twists, as the first five seasons of ‘Only Murders in the Building’ are available for streaming on Hulu.
