Be sure to tune in to the Rizzoli & Isles summer finale, entitled “Melt My Heart to Stone,” tonight at 9 p.m. (ET/PT).

When a statue breaks open to reveal a dead woman inside, Jane and Maura must find the killer quickly as the body count begins to rise. Back at headquarters, a new homicide detective is named to the squad. Meanwhile, Dennis Rockmond (guest star Eddie Cibrian) returns to Boston after disappearing on Maura and tries to woo her back. Lydia goes into labor. Colin Egglesfield, Daniella Alonso and Alexandra Holden also guest-star.
