“Rizzoli & Isles” is bringing its fourth season to a close Tuesday (March 18) with an episode titled “You’re Gonna Miss Me When I’m Gone,” in which Homeland Security steps in when a senator’s daughter is found murdered.

The squad rushes to solve the case, which could put national security at
risk. Meanwhile, Tommy (guest star Colin Egglesfield) and Frankie get
into a fight after Tommy starts slipping back into bad old habits. Finally, Jane reveals some shocking news that could change her life forever.

Well, that doesn’t sound good. Season 4 wraps up at 9 p.m. ET/PT Tuesday, and Season 5 is scheduled to premiere June 17 on TNT.

UPDATE: Rizzoli’s life-changing news turns out to be that Casey has been offered a command in the Balkans and wants Jane to go with him as his wife.
