The locations are beautiful right by the sea and the houses the main characters live in look like upper middle-class homes. Everything is just perfect except for the murders and the breakdown of a marriage.
The plots are pretty mundane. I guessed the motivations and murderers in 2 of the 4 plots and I'm pretty useless at whodunnits - I'd rather get a surprise at the end when we find out who the miscreant is. Running through everything is the marriage breakdown. I really can't understand why it was focused on so heavily. If it had impinged on the investigations and had led to someone getting away with another murder or crime, this would have been an acceptable use of the time spent on this theme. But it didn't. It just made the series frothier and more superficial than it needed to have been. It didn't help that the eponymous detective was so unlikable - stalking. telling his daughter tales, being nasty and unprofessional.
As usual, I watched till the end. I didn't hate it but there are far better things to have seen, I think. It was just a nicely numbing few episodes of escapism.
