The Mysterious Stranger

Detective Hercule Poirot boards the luxurious Orient Express, where he encounters a diverse group of passengers. Among them is the wealthy and unpleasant American, Samuel Ratchett, who seeks Poirot's protection, claiming his life is in danger. Poirot declines, sensing something sinister about Ratchett. As the train departs, a snowstorm traps it, setting the stage for a murder mystery. Ratchett is found dead in his compartment, stabbed multiple times. Poirot is tasked with solving the murder, and he begins by interviewing the passengers, each of whom has a potential motive and alibi.

A Cry in the Night

During the night, Poirot is awakened by a loud cry and a series of strange occurrences. The train is stopped by a snowdrift, and Ratchett is discovered dead in his locked compartment. The murder seems impossible, with no clear way for the killer to have escaped. Poirot begins his investigation, noting the peculiarities of the crime scene, including a stopped watch, a handkerchief with the initial "H," and a pipe cleaner. The passengers' testimonies are inconsistent, and Poirot senses a web of deceit.

The Locked Room

Poirot examines Ratchett's compartment, finding it locked from the inside. The evidence suggests multiple stab wounds, some delivered with great force, others weakly. Poirot deduces that the murder was committed by more than one person. He discovers a burnt note linking Ratchett to the Armstrong family, victims of a notorious kidnapping case. The investigation reveals that Ratchett was actually Cassetti, the mastermind behind the crime. Poirot realizes that the passengers may have personal connections to the Armstrongs.

The Gathering of Clues

The presence of a mysterious conductor and a woman in a red kimono further complicate the case. Poirot must untangle the web of deceit to find the truth.

Secrets and Lies

As Poirot delves deeper, he uncovers the true identities of the passengers. Many are revealed to be connected to the Armstrong family, each with a motive for revenge against Cassetti. The Countess Andrenyi is revealed to be Helena Goldenberg, Mrs. Armstrong's sister. The passengers' alibis begin to crumble, and Poirot realizes that the murder was a carefully orchestrated act of justice. The handkerchief and pipe cleaner are revealed to be deliberate red herrings, planted to mislead the investigation.

The Web of Connections

Poirot pieces together the connections between the passengers, revealing a conspiracy to execute Cassetti.

The Final Revelation
