Love the backdrop but the stories really have got increasingly thin as the series have progressed. Series 7, the latest one, was by far the weakest. Arresting someone just because they had the same initials as circled in a book? Really? And constantly letting police officers go and investigate crime scenes without a partner - when will they learn. But the main point was the plot, it starts with a group open water swimming, someone nearly drowns, no reference ever again. They deploy armed officers to an oil facility based on the suggestion "it's probably where they'll go". Just all feels very rushed and poorly thought through. And to the finale, which I will try to describe without spoilers, we have a key character who is one day prepared to die for the cause and the very next willing to throw their entire career away because they "think" someone has been incorrectly charged. Not great, by any means.
