Motive Season 3 Episode 10

The killer: Ashley Kirkwell, the victim: Dr. Garrison Osgood
Ashley is the former owner and operator of a strip club called the Blu Lounge, which was formerly called Purgatory. Garrison is a successful plastic surgeon who, in partnership with Dr. Lucy Everhill, owns a private clinic. The detectives are called to the clinic when the body of Dr. Everhill is found. While there, they encounter Dr. Osgood, who is still alive, albeit barely, covered in blood and holding a knife. He dies in front of the detectives uttering 'Purgatory' as his final word. This instantly makes him the chief suspect in Dr. Everhill's murder. Also, Angie talks to Sgt. Cross about her suspicion that she is being followed.
