This book, novelised by Charles Osborne, is quite intriguing and organizes narrative in a peculiar way, that could be easily performed in theatre, as it was some years after the publication in England.
It combines many aspects of the famous Christie's style, that is the familiar and middle class setting, the couple of detectives, I mean Poirot and his earnest friend Hastings, and furthermore a sort of political/scientific mistery, linked to the theft of an important scientific formula that is supposed to be linked to the murder of his discoverer.
This book mixes aspects of the traditional thriller narrative of Agatha and some more modern features, such as the political characteristics, that are quite connected to the writer's interest (or fear we could better say) in nuclear bombs and so on.
The familiar drama, here, is very clear: lies and secrets are useful for people to protect whom they care for. But who is actually lying for some other purpose, that is hiding the murder he committed?
The end is quite surprising, as always with Agatha Christie.
We can find a good and rapid rhythm in the story, and a particular attention to the description of the internal environments, especially the study of the scientist who has been murdered.
Great reading, thanks Agatha!
This book is a novelization of the play "Black Coffee" written by Agatha Chrisite. It does not read exactly like books actually written by Agatha Christie, and it is not the best Christie you could find out here but it's a worthwhile read.
