DNA confirms Duncan as Alan Killick's father and possibly a double killer and he is arrested. Then a perusal of Sally's files brings another suspect into the picture, literally - one who had good reason to dispose of Lizzie and who makes a confession of guilt. However Jimmy discovers that this person may not have murdered Sally but still finds both Duncan and himself in a dangerous situation before there is closure.
