Rizzoli and Isles quickly became the most watched cable show of the summer, returning to 6.6 million, up 18% from last season. Perception wasn't as lucky, returning with 4 million, down significantly from the 5.6 million that watched the series launch last summer. This is a rough summer so far for TNT, as King and Maxwell continues to flounder, and now Perception is down. Luckily, Rizzoli and Isles continues to be a bright spot.
