This is off the TNT website:
Brenda Johnson is a Southern CIA-trained detective who becomes deputy police chief over a newly formed L.A. homicide team. Her abrasive ways often rub male colleagues the wrong way; they also resent that she shot to the top without paying dues on the L.A. beat. But they can't deny that Brenda knows her stuff. When it comes to obtaining confessions that lead to courtroom convictions, she's a "closer."
I love how she is winning people over and am looking forward to next weeks episode and her maybe having a relationship with Fritz.
