The second series came out in May 2013 which was almost 2 years since the first series aired. I've not seen anything that indicates a third series or cancellation. There are three stories, each about 90 minutes, which cuts the length of the story down. The first series had 6 hour long programs with one story per two episodes so there's 25 minutes less story time after you remove the repeated opening credits. Jason Isaacs is Privite Eye Jackson Brodie.
The first story has Brodie kidnapping a girl, he was told he was returning her to her mother but that turned out to be a lie and he could be in trouble. He gets a big pile of cash that he then turns around and buys some fake passports from a scummy foreign guy who wants a favor on top of the cash. He's helping out an ex cop that bought the daughter of a crack whore. They will go to Australia for a new life. Even though he broke the law helping out it and the kidnapping debacle sure made me think Brodie is a schmuck. He also seems to get punched out more this series than last.
In the second story Brodie figures out who murdered a lady on a horse and the third story has the scummy foreign guy call in his favor. That doesn't go as well as the second storyline where Brodie helps a guy find out how his mother died.
Everything is well done on the programs but after Brodie's poor judgement on the first case I'm thinking poorly of the guy. No need to buy or rewatch. It's not like I don't have enough to watch and re-watch, I won't miss it.
