Someone asked what the murder 20 years earlier had to do with the events in this series. I think it was just one of many hits by the "Help Desk", and it got Venn and his brother into the story.
Mark and Hillman hadn't been sitting around waiting for these events. Hillman told Venn that he had been kept around to do jobs for the Help Desk, and was well taken care of for it. I suspect the same was true for Mark (who I also suspect killed Hillman before Hillman killed Venn). Now they were called out to deal with Gina because she wouldn't let her parents' deaths go, and maybe they were after Venn because he wouldn't let his brother's purported death go. Then they were to assassinate Wentworth, maybe to open a way for Morpeth to move in. That part's a bit murky. But Mark took out Morpeth and Styles to, once again, protect his brother.
I suspect that Venn went back into the prison at the end because he didn't want to be on the run for the rest of his life, but it would have wrapped things up nicely if he'd turned in that direction.
The length of this was good (four episodes); plenty of time to build a story and build tension, but not so long that it dragged out (like the French series Spiral that carries one case through about a dozen episodes).
