Did You Know?


The red-white-blue ribbon worn by Hastings is the 1914 Star; the bronze clasp surmounted indicates the wearer was in actual combat. Additionally, Hastings is referred to as "Lieutenant Hastings" near the beginning of the episode, and the markings on his uniform sleeve correspond with this rank. At some later point, he earned the title of Captain, which is how he is addressed in most episodes. See more »

Intriguing and nostalgic
27 March 2018 | by grantssSee all my reviews

World War 1 and British Army officer Arthur Hastings is recuperating in a quiet manor in the English countryside. When a woman is murdered in the household, Hastings enlists the help of an old friend to solve the mystery - Hercule Poirot.

Intriguing and quite nostalgic. This is the mystery that cemented the Poirot-Hastings partnership. So quite an historic feel to it.
