In reply to Lrunner:
Ive looked into this after enjoying Mystery Road (the series) followed by Goldstone.
... and being a bit confused.
Apparently it was Mystery Road film, then Goldstone.
Then... as they thought it worked well they created a stand alone series which didn't relate to either, just set with Jay as the main character.
The original film DVD is on my xmas list : ) having just watched Goldstone again which reminded me how good it was.
