I watched this all in a period of thirty six hours. It was the detective series that had everything - rich and powerful families, junkies, anarchist protestors, cops with a plausible back story, cross-border events. Yet the scriptwriters managed to mesh all of these disparate strands into a coherent whole.

The story was told in the present with flashbacks into the past. Each flashback brought us tantalisingly closer to the original murderer and why others were being committed. It was clear though that the present-day killings, although related to the bodies found during the drought, were being committed by someone different from the original assassin.

The script cleverly imputed different motives and reasons for the murders in the flashbacks and led the viewer astray on more than one occasion as the investigation progressed.

There was a final couple of twists at the end. The cops had caught their miscreant who had confessed but they were unaware that it was an elaborate game; the real killer had got away with it. Nonetheless, justice was done in a different way.

I was really impressed by this and I recommend it.
