We're still trying to get used to seeing Ted Danson not clap his hands, wink and crack open a bottle of something. It's been tough, but we're getting there. This week, a woman is found murdered after complaining to the police about a lock of her hair being cut off in an elevator. A clue at the scene leads DB and the team to suspect the culprit has a fetish for women's hair - and they realise they are searching for a serial killer when another woman dies in similar circumstances. Guest starring William Ragsdale (Justified) and Brianna Brown (Homeland).
