DS Justin Ripley
Ripley's dogged loyalty to Luther cost himself and his career a great deal. Demoted to uniform for a year, he now joins the new Serious and Serial Unit, older and wiser.
His high regard for Luther is unwavering; confident that Luther's intent is to be on the side of the angels. However, his regard is polluted by the knowledge that work for the angels can bring you too close to the devil. Can he keep on turning a blind eye to Luther's methods or will he be forced to challenge Luther's decisions?
