Poirot travels in the rarified circes of the rich and famous, but his cases aways involves both the upstairs and downstairs members of English society. Poirot, Series 3, is impeccably filmed, and provides a glimpse into a lost way of life; not just of manor houses and travels on the Queen Mary, but strict class separations that could be (temporarily) equalized by an event like a murder.
With the release of the Poirot series on Blu-ray, viewers can watch not only a wonderful depiction of 1920s and 1930s England, but also the definitive version of Agatha Christie's most famous character, Hercule Poirot.
