A fourth season of "Only Murders" was confirmed on the heels of the Season 3 finale dropping in October and setting up another murder for the central trio to solve.

"Only Murders in the Building is coming back for Season 4! Let the investigating begin..." the show said on social media.

Season 3 saw the series add Hollywood A-listers Meryl Streep and Paul Rudd to the cast, along with Ashley Park and Jesse Williams. Ryan Broussard, Da'Vine Joy Randolph and Michael Cyril Creighton returned from Season 2.

USA TODAY TV critic Kelly Lawler gave the third season 2½ out of 4 stars, commenting that the "slapstick shtick of 'Only Murders' is in danger of getting old" and that the addition of Streep to the cast "brings a surprising sense of whimsy" to the series.
