Only Murders in the Building is a gleefully clever mystery comedy on Hulu set in the Arconia, a fictional luxury apartment building on New York City’s Upper West Side. Three unlikely neighbors — a faded true crime TV star, a failed Broadway director, and a guarded young artist — bond over their shared obsession with true crime podcasts and find themselves investigating a murder in their own building, which they document as a podcast of their own.

The chemistry between Steve Martin, Martin Short, and Selena Gomez is the show’s irresistible engine, combining the effortless comic timing of two legends with Gomez’s unexpectedly deft deadpan. The series layers genuine mystery plotting with warmly observed character work and an affectionate portrait of New York City’s apartment-building community, where strangers share walls for years without ever truly knowing each other.

Now in its fourth season, Only Murders in the Building has established itself as one of Hulu’s crown jewels, regularly attracting high-profile guest stars — including Cara Delevingne, Paul Rudd, Meryl Streep, and Eva Longoria — and maintaining the playful self-awareness that made it an instant hit. It is a rare series that has grown richer and more confident with each passing season.
