When does 'Only Murders in the Building' finale come out? Release date, cast, where to watch

Season 4 spoilers ahead!

It's been an eventful season for Arconia's chaotic murder-solving trio.

In between solving yet another murder, Mabel, Charles and Oliver are also working on a film on their podcast "Only Murders in the Building" starring Eugene Levy, Eva Longoria and Zach Galifianakis, planning Oliver and Loretta's upcoming shotgun wedding and fleeing their apartments to Charles' sister in Long Island to escape the killer who says they're "watching them."

While the trio appears to have found their killer in the second-to-last episode of the season, it is not confirmed if *spoiler alert* Marshall Pope was the one who killed Charles' stunt double Sazz Pataki and if Sazz was even the intended target.

With just one episode to go till the entire story unfolds, here's what to know about "Only Murders in the Building" Season 4 finale including release date and cast.

Our critic's take: 'Only Murders' doesn't change at all in Season 4. Maybe that works for you!
