It would be infinitely more enjoyable without the dreadful Scot who's about as menacing as a poodle except the poodle could act better. DCI Gray could just as easily been after him on her own or with a credible investigation team. From the teasers for next week she arrests him for murdering Justin so it will be interesting how they manage to work that one in, given Luther doesn't have a shotgun and the crazy guy does. You can feel Alice coming even before she's mentioned. I love Alice.
