A drama series that has become one of the signature shows on TNT will be coming back for a sixth season, after the cable channel announced it’s picking up another season of “Rizzoli & Isles.”

The show finished the past summer as the No. 1 series on basic cable, the channel notes in its announcement, adding that it has been in basic cable’s Top 5 series for five consecutive years.

“Season five of ‘Rizzoli & Isles’ is set to return with new episodes in early 2015,” the announcement notes. “TNT has ordered 18 episodes for season six, which is slated to launch in summer 2015. ‘Rizzoli & Isles’ is produced for TNT by Warner Horizon Television and Bill Haber’s Ostar Productions, with Haber and showrunner Jan Nash serving as executive producers.”

The series stars Angie Harmon and Sasha Alexander.
