You will find Agatha Christie, the author, at her best here. What a brilliant way of creating a crime scene out of nowhere and then producing one after another twist in the tale with numerous characters chipping in with their roles to play. The voice of Dan Stevens in the audio book is one of the major reasons of its success, who outshines with his perfect and neutral accent that he does with so much professional ease.
The other books by Agatha Christie such as Agatha Christie: An Autobiography and Murder on the Orient Express are great examples of masterpiece work by the author. In this book, the characters are so rich and classy with great acting skills. Remember, this book is not a direct narration of the novel, but this crime story is dramatized.
The book again covers a mysterious murder, where the great detective Hercule Poirot with his sheer brilliance and detective expertise untangled a very complicated murder. The circumstances never gave any hope or idea to the listener that this mysterious murder would get to its poetic justice in the end, but it did. Again a murder on a trip, but still the story and characterization are totally fresh and different from her other book of mysterious murder in a train, Murder on the Orient Express.
Agatha Christie wrote this novel more than 80 years ago, but it seems to be quite relevant even today. People who have already read the novel or even the audiobook finds it great pleasure and a source of entertainment to listen it again and again, despite even knowing the story. This is primarily because of the great coordination between the writing mastery of Agatha Christie and the powerful performance of the ensemble cast with great dramatic narrations.
