The 66-year-old actress will play Constance Isles, Maura's elegant adoptive mother who is, of course, impeccably styled. Her seemingly perfect mother also happens to be a brilliant art historian. Add that to the fact that her biological dad is a mob boss, and Maura really lucked out!
Rizzoli & Isles will return for Season 2 on Monday, July 11 at 10/9c on TNT. Bisset's first episode will air in early August.
