A glamorous overnight train, a murdered heiress and missing jewels give Hercule Poirot a compelling case in Agatha Christie’s 1928 novel The Mystery of the Blue Train. Its London-to-Riviera journey makes an inviting setting for a classic puzzle—and the travelers’ connections are part of what Poirot must untangle.
What is The Mystery of the Blue Train about?
Ruth Kettering is found murdered during a journey on the Blue Train, and her valuable jewels have disappeared. Poirot investigates, looking beyond the crime scene to the people aboard and the relationships that may connect them. The premise offers the pleasures of a contained train mystery without giving away its solution.
Why pick it for Sunday reading?
Christie makes the journey itself part of the appeal: the train carries its passengers from London toward the Riviera, bringing glamour and a close-knit cast into the same moving setting. The missing jewels add a clear mystery to follow, while Poirot’s investigation gives the reader a reason to watch how each traveler fits—or does not fit—into the puzzle.
What was happening while Christie wrote it?
Agatha Christie Limited says Christie wrote part of the novel in the Canary Islands in early 1927 and describes the writing as an ordeal amid the events following her mother’s death and her separation from Archie Christie. That context gives a glimpse of the circumstances around the book’s creation; it should not be taken as a complete explanation of the novel’s style.

Yes. A 2006 television adaptation stars David Suchet as Poirot. According to Agatha Christie Limited, it moves the story to the late 1930s to fit the period of the surrounding Poirot series. That is a change from the novel’s original publication context; current streaming availability is not established here.
