Following a week-long hiatus, "Rizzoli & Isles" season 7 is back with its 6^th episode. In the upcoming segment, Jane and Maura will try to solve a double-murder case with a supernatural twist.

Titled "There Be Ghosts," the episode will follow team partners Jane and Maura as they probe into an old ghost story that seems closely connected with the double-murder case they are currently investigating. What makes this case interesting is that all the members of the hospital staff believe that the culprit for the crime is a ghost. However, Jane maintains that the case should be treated as a homicide and should not be associated with supernatural beings.

In the promo trailer for the episode, Maura tells Jane that a ghost may have to do with the killings in the hospital, but Jane seems not to believe her, saying it's a homicide.

On the other hand, Angela will try to convince Frankie to stop minding his and Kent's individual differences so they can freely talk and not avoid each other. The upcoming episode will see Frankie accept the invitation of Kent to go to a concert with him.

The official synopsis for the episode reads, "Jane and Maura must unravel old ghost story in order to solve a double murder at a hospital. Angela convinces Frankie to stop avoiding Kent and accept his invitation to a concert."

Episode 6 did not air last week to give way to a three-hour marathon special as part of the Fourth of July celebrations.

"Rizzoli & Isles" season 7 airs every Monday night on TNT.
