The Mystery of the Blue Train Plot Spoilers Summary

As an avid reader who has listened to innumerable audiobooks, I just discovered a treasure that I simply had to share. “The Mystery of the Blue Train” by Agatha Christie piqued my interest not just because of its intriguing title, but also because I am a huge fan of Hercule Poirot mysteries. After enjoying “Murder on the Orient Express,” I was excited to read another Christie story involving a beautiful train and a thrilling mystery. This review of “The Mystery of the Blue Train” is one of my most recent deep dives into great mysteries, and it will not be the last. Here’s what makes this book so engaging.

Plot Summary

“The Mystery of the Blue Train” takes readers on a voyage on the sumptuous Blue Train, which runs from London to the French Riviera. The plot focuses on the murder of Ruth Kettering, a rich American heiress, and the theft of her valuable jewels, including the famous ruby known as the “Heart of Fire.”

Ruth Kettering’s life is far from ideal, despite her money. She is unhappily married to Derek Kettering, who is more concerned with his extramarital escapades than with his wife. Ruth intends to leave her husband and meet her lover, the Comte de la Roche, in the south of France. However, catastrophe comes when Ruth is discovered dead in her compartment, her face horrifically mutilated, and her prized jewelry gone.

Hercule Poirot, the renowned Belgian detective, happened to be on the same train. Rufus Van Aldin, Ruth’s father, appoints Poirot to investigate the murder. As Poirot investigates the case, he finds a labyrinth of deception, jealousy, and greed, which eventually takes him to the murderer.

Analysis and Comparison

“The Mystery of the Blue Train” is comparable to “Murder on the Orient Express,” notably in its location onboard a luxury train and complex narrative involving several suspects. While “Orient Express” is a masterclass in communal guilt and moral complexity, “Blue Train” is more of a straight-forward whodunit, with an emphasis on individual avarice and treachery.

Christie’s hatred for the work, as revealed in her autobiography, contrasts with the book’s overall response by readers and reviewers, who praise its rich atmosphere and sophisticated storyline. The book also introduces aspects that would become commonplace in her subsequent works, such as the imaginary community of St. Mary Mead and recurrent characters such as Mr. Goby.

Conclusion

Despite being one of Agatha Christie’s least favorite works, “The Mystery of the Blue Train” is an engaging and entertaining mystery. It demonstrates Poirot’s logical skill while weaving a complicated story of love, treachery, and money. For aficionados of classic mysteries, this book is a must-read, offering an intriguing peek into Christie’s maturing narrative skill.
