I thought all the shows were delightful! Not to be taken too seriously, yet with enough suspense to keep one watching...the clothing, cars, homes...all the "sets" were lovely, authentic enough to keep the viewer in the nuances of the time, a lot of fun... The Tommy and Tuppence stories were the same informative enjoyment to read, and I thought these episodes were as good as the reading, although not the same...I really enjoyed them, and I'm hoping there are more! The actors couldn't have been better suited to their roles...and although Tuppence was, at times, little more independent than usual for the time, I found it refreshing and humorous, and Mr. Walliams played her opposite to perfection. The final episode, was grim enough, surely, to forgive any unduly perceived frivolousness previously...I'm thinking Ms Christie would have enjoyed these shows!
