S4, E1: Blake returns home to Ballarat without Jean, to find himself thrown straight into another murder investigation; Ballarat is hosting a stopover in a round-Australia race, and a young mechanic has been found dead underneath another competitor’s car. There’s pressure from business to wrap up the investigation quickly, but Blake has dealt with that kind of interference before. But when Lawson is run down, Blake finds himself facing a very different case. And Jean’s absence – and the appearance of an intrusive reporter – only makes things more complicated.
