Season 5 sees Luther (Idris Elba) back in the field with new partner. Catherine Halliday (Wunmi Mosaku) comes from the private sector and Schenk (Dermot Crowley) tells Luther under no uncertain terms he needs to play by the book.
As the two investigate a series of brutal, bizarre murders, Luther starts to realise that Halliday might have a streak of “pragmatism” within her and that working together might not be so bad after all.
Unfortunately a fresh start is not on the cards as Luther’s past simply will not rest. With Alice (Ruth Wilson) back in the picture and George Cornelius (Patrick Malahide) out for revenge, Luther might have finally bitten off more than he can chew. As he frantically tries to fix things before his carefully constructed web of lies comes crashing down, more and more of the people around him start to get sucked in and the case starts to suffer.
The criminal case in this season is probably the best ever. Hermione Norris is just incredible playing psychiatrist Vivien Lake and her strange relationship with her clients and her creepy surgeon husband (Enzo Cilenti) is so deliciously shady. They are a truly dastardly trio and watching them is like watching a car crash that you just can’t look away from.
I thought Halliday was a great addition to the cast and a bit of a breath of fresh air after the hole left by Ripley and her dilemma in trying to figure out whether or not to trust Luther is much like that of the audience’s.
This time we get a look into what really happened between Luther and Alice. It casts a fairly unpleasant light on John, questioning whether his desire to solve crimes at any costs is about the victims and justice or if it’s more about his own desire to triumph and his belief in his superiority. I have to admit that I struggled a little with that element of this season because some of Luther’s behaviour borders on making him unlikeable. His saving grace thus far has been that although some of his methods are questionable he has a good heart. In this season I started to wonder if he had any kind of line he wouldn’t cross to protect himself. I also started to feel really sympathy for Alice. I mean yes, she is a sociopath but Luther has really put her through the ringer… and is he that different from her?
The season ended on a cliff hanger and I honestly don’t know where the showrunners are going to go with it but I guess we’ll see in due course.
