Michael Cyril Creighton is remaining tight-lipped about the Only Murders in the Building season 5 finale - but he did drop some hints. "What I will say is, I've seen it, I've read it, I was there. I think it is surprising and satisfying and wild," Creighton teased to Us Weekly during an exclusive interview. "There's a lot that's going to happen." Season 5 of the beloved Hulu show centers around sleuths Mabel Mora (Selena Gomez), Oliver Putnam (Martin Short) and Charles Haden-Savage (Steve Martin) investigating the death of Arconia's doorman Lester.
