I love whodunnits and this is not one, which was greatly disappointing because that was the whole reason I watched the show. The only meagre mystery was in episode 4 and 5 out of 6. Other than that, it is an entirely watchable show. Nothing brilliant. I would have given just 6 stars but added one extra for for fine acting from so many of my favourites. I only wish I had not been misled by the tagline on imdb and even the trailer.
