After weeks of speculation, it was confirmed at the Episode 100 Celebration that the two-time Emmy-winning Cagney & Lacey alum will guest-star on the milestone episode of the TNT procedural. While there are no details available on Gless’ character, she appears to be in a prison jumpsuit in photos that circulated on social media. And we do know Jane (Angie Harmon) is set to go undercover at a county jail in the episode titled “2M7258-100.”

The 100th episode will air Monday, July 25 at 9/8c, as part of Rizzoli & Isles’ seventh and final season.
