This show has the premise of something brilliant. A murder(s) in an isolated area, with multiple suspects with unknown motives. A perfect replica of any Agatha Christie show which should have sated the most ardent mystery lover but didn't really in the end.
A lack of character development failed to offer the mystery required for such a show. They are never truly revealed even at the end. A motive for suspects is always a compelling factor, but again, never developed or even really tempted to be known, not even at the end.
The murders are not deeply investigated, nor properly made to be indifferent. There are clues thrown in, namely obvious because of their obscure appearance, which mean something, but never expanded on, and end up as just a forgotten mention.
In the end, the killer and motive are revealed. But..... will it be enough to convince? A very mild, laid back finale ends the series almost quietly. Possibly disappointing to some, but expected these days as shows become less original in surprises.
Definitely worth watching, just for the thrills of guessing. Nothing too new but produced well enough to warrant watching 7 episodes.
