Kumail Nanjiani joins the cast of Only Murders In The Building for season four... after Eugene Levy, Eva Longoria and Molly Shannon landed parts

Kumail Nanjiani could be the latest suspect to come under scrutiny in Only Murders in the Building. 

The Ghostbusters: Frozen Empire star, 46, has signed up as the newest cast member of the popular crime dramady, according to Variety

It's unclear what his role will be in the Emmy winning Hulu hit, as the show's producers are keeping the plot under wraps.

What fans do know is that Mabel, Charles and Oliver, played by stars Selena Gomez, Steve Martin and Martin Short, respectively, will make a trip to Los Angeles, before returning to their beloved Arconia, as they search for Saz's killer.

In the season three cliffhanger, the stunt double for Charles-Haden Savage, played by Jane Lynch, was found dead in the actor's apartment.

Because Saz was dressed just like Charles, the trio suspected that the Brazzos star may have been the intended victim. 

Other additions to season four include Eugene Levy, Eva Longoria, and Molly Shannon.

Meryl Streep will reprise her role as blossoming Broadway star and Oliver's love interest Loretta Durkin. 

Stills of Gomez, Martin and Short on the backlot in Los Angeles were shared over the weekend by the show's Instagram page. 

'The besties are back. Season 4,' was posted next to a series of snaps with the stars shivering in the cool winter weather, seated in their chairs. 

'First day of school at OMITB. What fun to be back for season 4!' Martin wrote next to the pictures on his own social media page. 

Nanjiani is no stranger to Hulu audiences. 

The Pakistani-American actor earned an Emmy nomination for his role as Somen 'Steve' Bannerjee in the fact-based limited series Welcome to Chippendales.
