A review by grinningcat
The Big Four by Agatha Christie

4.0

This is my least favorite of all of the Hercule Poirot mysteries. It’s the Poirot version of a spy novel, and spy novels are not Christie’s strong point. The book is considered unfilmable, although there’s a David Suchet version that is an adapted extract from the book. Hastings is back. This and the appearance of Poirot’s brother Achille are the highlights of the story. However, even the worst Christie is better than most other mysteries.
