Actor-comedian Molly Shannon has boarded the cast of the fourth season of the hit crime comedy series Only Murders in the Building.

In the upcoming season, three-time Emmy nominee Shannon will play the role of a high-powered businesswoman from Los Angeles who finds herself drawn into the world of the investigation in New York.

The series stars Charles, Oliver and Mabel as Steve Martin, Martin Short and Selena Gomez respectively. The three neighbours in an apartment come together to do a podcast based on the murder of their common neighbour. While the second season saw them probe into the death of another resident, the third season features Paul Rudd as a famous actor who gets murdered. Meryl Streep also appeared in the show. Towards the end of the third season, the makers left the audience with a cliffhanger where Sazz (Jane Lynch), Charles' stunt double, gets shot by an unknown assailant.

Further details about the plot of the new chapter are being kept under wraps.

Disney Television Group President Craig Erwich revealed in a Deadline interview that the trio will kick off the new season with a trip to Los Angeles before returning to The Arconia in their search of Saz’s killer.

Attached to 20th Television, the show is co-created by Steve Martin and John Hoffman. They also executive produce alongside Short, Gomez, Dan Fogelman and Jess Rosenthal. The first three seasons of the series are available to stream in India on Disney+ Hotstar.
