Season 3 is expected to include 15 episodes (actual number of episodes may vary). Angie Harmon and Sasha Alexander are back on the case as Rizzoli & Isles continues for a third explosive season. As the chart-busting second season came to a close, Jane shot Maura’s estranged father, crime boss Paddy Doyle (guest star John Doman), as he tried to defend Maura against an assailant — an incident which has driven a deep wedge between the two friends and colleagues. Jane and Maura will work hard to set aside their differences as they investigate a number of complex and troublesome crimes, including the murder of a female college student, a killer who has turned the transit system into his personal hunting ground and the brutal murder of two young homeless veterans. Brian Goodman joins the cast this season as a series regular, starring as Lieutenant Detective Sean Cavanaugh, whose knowledge of the hardscrabble back alleys of Boston and history as a detective make him the perfect choice to head the Homicide unit.
