And that was series one. Tony Gates is a tragic anti-villain, the kind of character who makes some bad decisions (mostly his adultery) and is consequently cornered from all sides as if it were a game of chess. There's no justice at the end of the story but there are hints that drug lord Tommy is actually not the top dog.
The conclusion to the police raid disaster that's followed Steve Arnott seems conveniently undecided but at the same time it highlights the complicated combination of professional and human behaviour.
There's the law to protect us and decide for us, equally - at least that's the idea - but the law can't handle moral issues from a personal point of view. What's "legally right" can do more harm than good, the collateral damage that goes with the territory.
But that doesn't happen in this story and I'm not sure if that makes me feel relieved or dissatisfied.
The complex police ranks, and also military ranks, and maybe also hospital ranks (!) make it difficult to talk about the characters in their professional capacity, so I'm just going to say that I love the political goings-on, the dealings and the compromises, the loyalty and the self-serving antics.
Series 2, I think that had something to do with the mysterious misinterpretation of a call-up....or maybe it wasn't a misinterpretation.
