A 15 episode season four will air in 2013.
“Anchoring a new night in its third season, Rizzoli & Isles has proven itself to be a strong and enduring hit, not only in terms of the great storylines and performances, but also in terms of the show’s stellar ratings,” stated Michael Wright, president, head of programming for TNT, TBS and Turner Classic Movies. “We’re thrilled that Rizzoli & Isles will continue to be a vital part of the TNT lineup.”
The Plot:
In the series, Harmon plays Jane Rizzoli, a tough-as-nails Boston police detective, and Alexander is Maura Isles, a smart, impeccably dressed medical examiner from a privileged background. Despite being complete opposites, the two women share an offbeat chemistry and strong working relationship that lets them solve complex murder mysteries in the city of Boston.
