Warning: Spoilers for Season 4!

This season has been quite the journey for the quirky trio solving murders in Arconia.

As they tackle yet another murder, Mabel, Charles, and Oliver are also busy producing a film for their podcast “Only Murders in the Building,” featuring Eugene Levy, Eva Longoria, and Zach Galifianakis. They are simultaneously preparing for Oliver and Loretta’s wedding and have fled to Charles’ sister’s place on Long Island to escape a killer who claims to be “watching them.”

Although the group seems to have identified the murderer in the penultimate episode, it’s still uncertain whether *spoiler alert* Marshall Pope is responsible for the death of Charles’ stunt double, Sazz Pataki, or if Sazz was actually the target.

With only one episode left to reveal all the answers, here’s everything you need to know about the Season 4 finale of “Only Murders in the Building,” including its release date and cast details.
