It seems to me that this mini series is erring on the side of mental torture and horror (quite the obvious statement if you’ve seen it, I know). Each character despite their surface appearances (and isn’t this a classic portrayal of the stiff upper lip from that period?) are haunted by their past deeds. We are treated, if that is the correct word, to the Doctor’s particular horror in the first episode where we see a hospital trolley, a body covered with a sheet & liberally splashed with blood. Clearly such a scene will haunt even the hardiest of souls. Which is exactly what we have seen in this episode.
Interestingly, two of the characters have come to accept their fate. Perhaps they are tired of living out their pasts and want to let it go. They know that their time is up and will not resist. For those who are left, fear grips time and again bringing finger pointing to a new level.
A weapon has gone missing and the remaining characters resort to searching all the rooms together. Trust has been shattered as each person strives for survival. Only Charles Dance’s character seems unperturbed by what is happening. Perhaps because he has already lived his life.
Of the remaining cast, three could be classed as respectable members of society; a judge, a doctor and a policeman. Dare we dismiss them from our list of potential candidates for killer? I think not.
Who do I think is the killer? I think I’ll keep my guess close to my chest for now. If it’s one thing I’ve learned from Agatha Christie, it’s never who you think it is.
