We enjoyed Ms. Walker in Spooks (Mi5) and River. She seems ageless. In some of her roles, she look like your aunt, while sometimes being very pretty (I mean that in a good way). In this entry, she leads a homicide team checking out, in the first two seasons, 2 separate cold cases. We get to know Nicola's character, and most others quite well (a Hallmark of Brit cinema).
As well as good conflict & character development, the show benefits from crisp pacing (6 episodes of 45 mins instead of 8x65). If you are a binge watcher (thank you Netflix and BritBox), you can sample a season in 2 days without booking off work! We found Season 2's storyline superior to the first one. There is a whodunit element to the series, but, as I wrap up Season 2, I can honestly say the writers have played it close to the vest. Enjoy!
Footnote: Both seasons involve cases involving 'deviant' sexual behaviour, which is not shown, but discussed, as related to the crimes being investigated. Hence, proceed at own risk.
