In season four, Charles, Oliver & Mabel wrestle with the shocking events at the end of season three surrounding Charles's stunt double & friend Sazz Pataki. Questioning whether Sazz or Charles was the intended victim, our trio's investigation leads them all the way to Los Angeles where a Hollywood studio is readying a film about the Only Murders podcast. As our amateur sleuths race back to New York, they embark on an even more epic journey - traversing their building's courtyard to delve into the twisted lives of the Arconia's West Tower residents.
