DCI Eastwood tells Burns that he took a call on Olson's phone which was made at a hotel by rogue cop Rob Breedlove, whom they link to Aaron Monroe, his businessman father Morgan and a prostitution racket. When quizzed about it Breedlove kills himself but Burns confronts Morgan Monroe with his findings. Spector is censured by his boss for making an impromptu and empathetic house call to his client Liz Tyler, a battered wife whose husband James has complained about him. However Spector ensures that Liz goes to a refuge whilst arranging for her husband's arrest. Spector sends a bizarre, anonymous letter to Sarah Kay's father, claiming he would not have killed her if he had known she was pregnant. Stella believes it is less a case of remorse than annoyance that his 'perfect' murder was tainted but allows Mr Kay to make a public appeal nonetheless. A friend of pathologist Reed Smith comes forward and tells Stella she once met a one night stand whom she knew only as Peter who tried to throttle her whilst having sex and wonders if he is the murderer. Whilst she is being interviewed Spector kills his next victim and her partner.
