Only Murders in the Building Season 5 Episode 1, “Nail in the Coffin,” kicks off the three-episode premiere. During it, Charles, Oliver, and Mabel begin to piece together clues about what happened to Lester, even after the police rule his death an accident.

What Happened on the Previous Episode?

Previously on Only Murders in the Building, Charles, Oliver, and Mabel solved Sazz’s murder. Jan helped save Mabel from Sazz’s killer — the dorky writer, Marshall, who had a darker side that no one saw coming.

Only Murders in the Building Season 4 Episode 10, “My Best Friend’s Wedding,” ended with Oliver and Loretta getting married at the Arconia. It’s was a sweet note to end the season on, but naturally the show had to throw one final twist our way by revealing that yet another person had died in the building: Lester.
