The Closer is coming to a close.

The series, by far the biggest hit in TNT history, will air four more episodes of season six, and then 15 more of season seven before calling it quits.

“It’s impossible to fully express our appreciation to Kyra Sedgwick, series creator James Duff and all of the other talented people who brought The Closer to TNT viewers,” said Steve Koonin, president of Turner Entertainment Networks. “The Closer was a pivotal series in setting a new course for TNT’s original programming, while also serving as a prime example of the storytelling strength possible on cable television.”

Adds the Emmy-winning actress:

“I cannot fathom how difficult it will be to say goodbye to the incredible family we’ve created on The Closer. I will always be grateful to James Duff for his love and friendship, as well as for creating such a rich and complex character who I have loved living with year after year.
