Trimmed down to 90 mins this, might be an interesting mystery - but stretched out to 3 hrs it's numbing.
This is sad because there are interesting plots elements, the acting and settings are good, and the characters have plenty of depth.
Funnily enough, I solved whodunit in the first episode with a single observation... a clue that is never mentioned in the story. Here it is (spoiler):
When the husband rushes to the sound of a maid screaming, he sees his wife lying on the carpet bleeding from a head wound. His reaction is to comfort the maid - anyone else would have rushed to check his wife. The only reason for him not to do so is that he already knew her injury was fatal - he was the killer. Now if only I'd stopped watching there and saved myself two hours!
It was alright-did not inspire or excite as a whodunnit. An interesting scenario and colourful characters; helpful prompts that we were rewinding to explain certain characters' stories in the build-up to the murder. I did like the 50s feel about the story but it is not one i would re-visit.
Tony Boyle comes out way the best effort. Bill does his shake of head, and looking very frail. Agatha probably wonder what is going on. Fills a space in the evening.
