Their beloved doorman, Lester, died under suspicious circumstances outside the Arconia. Therefore, the trio refused to believe it was an accident .
The season took viewers on a wild ride through New York’s underbelly. It introduced powerful billionaires, old-school mobsters and a hidden casino beneath the Arconia. As a result, the ending delivered one of the show’s biggest twists yet while setting up a thrilling sixth season across the pond .
Release Date and Episode Schedule
Only Murders in the Building Season 5 premiered on September 9, 2025. Hulu released the first three episodes on the premiere date. After that, one new episode dropped every Tuesday. The season consisted of ten episodes in total. The finale aired on October 28, 2025 .
The show has been a massive hit for Hulu throughout its run. It currently holds a 97% critic rating and 90% audience score on Rotten Tomatoes .
The Plot: Who Killed Lester the Doorman?
Season 5 followed Charles, Oliver and Mabel as they investigated the death of their longtime doorman, Lester Coluca. Authorities initially ruled his death an accident. The trio, however, suspected foul play from the start .
Early in the season, Oliver discovered another dead body. The victim was Nicky Caccimelio, a missing mobster. His body lay in the dry cleaning shop adjacent to the Arconia. The clues quickly led the podcasters down a dark path .
Their investigation uncovered a hidden casino in the basement of the Arconia. Nicky had been running the gambling operation. The case soon drew them into a dangerous web of organised crime and high finance .
The Season 5 Cast
The main trio returned for another season of crime-solving hijinks. Selena Gomez played Mabel Mora. Steve Martin portrayed Charles-Haden Savage. Martin Short played Oliver Putnam. Michael Cyril Creighton also returned as Howard Morris .
Season 5 featured an incredibly star-studded cast of recurring guest stars. The new additions included:
- Renée Zellweger as Camila White, an interior design mogul
- Christoph Waltz as Bash Steed, a tech genius
- Logan Lerman as Jay Pflug, a nepo baby
- Keegan-Michael Key as Mayor Beau Tillman
- Téa Leoni as Sofia Caccimelio, Nicky’s wife
- Beanie Feldstein in a recurring role
- Jermaine Fowler in a recurring role
This marked the show’s most star-studded season yet. The collective Oscar power of Zellweger and Waltz added serious prestige to the already beloved series .
The Three Billionaires
The central mystery revolved around three billionaires vying for a casino bid. Camila White, Bash Steed and Jay Pflug had dubious ties to Nicky’s gambling operation. Each had a motive for wanting Lester out of the way .
Their competition to turn the Arconia into a casino drove much of the season’s tension. As the trio dug deeper, they uncovered a scheme that threatened the very existence of their beloved building .
Who Killed Lester? The Shocking Reveal
The eventual killer turned out to be a jaw-dropping revelation with huge implications. New York City Mayor Beau Tillman, played by Keegan-Michael Key, was responsible for Lester’s death .
Mayor Tillman had been having an affair with Sofia Caccimelio, Nicky’s wife. When Nicky discovered the affair, he flew into a rage at the underground casino. The mobster severed Tillman’s finger with a meat cleaver. Lester later retrieved the finger as evidence and hid it in the shrimp at Oliver’s wedding reception for him to find .
Mayor Tillman chased Lester and caused him to fall into the fountain, resulting in his death. At the end of the season, Lester even tried to warn the trio about Tillman. Unfortunately, his final text message was autocorrected to read “It’s beautiful” instead of naming the mayor .
Who Killed Nicky Caccimelio?
Nicky’s death played out as an accident during the chaos of the confrontation. To stop the enraged mobster, Lester struck him on the back of the head with an elevator crank. Nicky then stumbled onto Lester while still holding the meat cleaver. He accidentally killed himself in the process .
The three billionaires cleaned up the aftermath to protect Mayor Tillman. They also wanted to preserve their bids for the casino. Both deaths were accidental but unavoidable in the larger scheme of the conspiracy. The Arconia was ultimately saved, and the residents could remain in their homes .
The Season 5 Finale Twist
The season finale set up an exciting new direction for the show. Charles, Oliver and Mabel were listening to their old nemesis Cinda Canning’s podcast, The Girl with the Curls. Cinda discussed her investigation into a murder in England. She revealed her prime suspect was being threatened by someone dangerous .
Suddenly, the scene cut to a woman with red curly hair stumbling across New York towards the Arconia. She collapsed and died right outside the gate. When Charles, Oliver and Mabel turned the body over, they discovered the woman was actually Cinda, wearing a wig .
The trio will likely complete Canning’s investigation into the murder following her death. This cliffhanger sets up the recently announced sixth season, which appears to take the gang across the pond to England .
Season 6: What We Know So Far
Hulu has officially renewed Only Murders in the Building for a sixth season. The show’s renewal came after the continued success of the series. The main trio of Selena Gomez, Steve Martin and Martin Short will return .
The finale’s cliffhanger suggests the sixth season will relocate to England. Charles, Oliver and Mabel will likely investigate Cinda Canning’s murder while also solving the English case she was working on. This new setting promises to breathe fresh life into the beloved mystery comedy series .
Conclusion
Only Murders in the Building Season 5 delivered another thrilling mystery with an emotional core. The death of beloved doorman Lester gave the trio their most personal case yet. The star-studded cast and shocking twist ending reminded viewers why this show remains one of television’s best comedies.
With Season 6 now on the horizon and the gang apparently heading to England, fans have much to look forward to. Consequently, the Arconia’s revolving door of mystery and mayhem shows no signs of closing .
