“Murder on the Orient Express,” written by Agatha Christie, is a classic example of the mystery genre that has captivated readers since its publication in 1934. The novel is a masterful whodunit featuring one of Christie’s most famous detectives, Hercule Poirot. Set aboard the luxurious Orient Express train, the story explores themes of justice, morality, and the complexities of human nature. With a gripping plot, rich character development, and Christie’s signature twist, the book remains a landmark in detective fiction.

The novel begins with Hercule Poirot, the renowned Belgian detective, boarding the Orient Express for a journey from Istanbul to Calais. Poirot, who is traveling to London, encounters a diverse array of passengers on the train, each with their own stories and backgrounds. The tranquility of the journey is abruptly shattered when Samuel Ratchett, a wealthy American businessman, is found murdered in his compartment.

As the Orient Express winds its way through Europe, Ratchett is discovered dead, his body riddled with multiple stab wounds. Poirot, who is also a passenger on the train, is asked by the train’s director, Monsieur Bouc, to investigate the murder. Poirot agrees, and the investigation begins. The detective interviews each passenger, uncovering a complex web of motives and relationships.

During his investigation, Poirot learns that Ratchett had received threatening letters prior to the journey. As he delves deeper, he discovers that Ratchett was actually a gangster named Cassetti, infamous for kidnapping and murdering a child named Daisy Armstrong. The Armstrong family, particularly Daisy’s parents, had been devastated by the crime, and Poirot starts to suspect that the motive for Ratchett’s murder might be linked to this tragic case.

Poirot’s interviews reveal that several passengers are connected to the Armstrong family, and their motives for seeking revenge on Cassetti become clearer. Each passenger has a unique reason for wanting Cassetti dead, and Poirot discovers that the passengers may have acted together to exact justice.

Poirot presents two possible solutions to the case. The first is that an unknown stranger committed the crime. The second, and the more plausible one, is that all the passengers were involved in the murder as a form of collective justice. The latter theory posits that they planned and executed the crime together to avenge Daisy Armstrong’s death.

Hercule Poirot is portrayed as meticulous, methodical, and highly perceptive. His attention to detail and his psychological insight into the characters’ motivations are central to unraveling the mystery. Poirot’s character showcases his dedication to justice and his belief in the moral complexity of human behavior.

Ratchett, or Cassetti, is depicted as a ruthless and cold-hearted individual whose past crimes have earned him a number of enemies. His character is essential for understanding the motive behind his murder and the moral ambiguity of the story.

The diverse cast of passengers each brings their own background and motivations into the mix. Notable characters include:
