Everybody's Gotta Learn Sometimes
performed by Beck

A serial killer is targeting women alone at night, taking a piece of jewellery from each of them and giving them to his unknowing wife. He escalates rapidly, and Luther's team is forced to enlist the help of his wife in order to track him down. He is successfully taken alive, but his wife assaults him in a fit of rage, striking him with a hammer in the back of the head. In an attempt to win Luther's friendship, Alice impersonates a doctor and lights a fire in the hospital, taking advantage of the distraction to fatally smother Henry Madsen.
