Extended data:

Hercule polo, a famous Belgian detective, solved an internal case for the French army in Aleppo, Syria, and took the Toros Express to stempel, Turkey, where he planned to transfer to Europe. In the carriage, except Poirot, there are only two British passengers, one is a British officer in India, and the other is a dignified lady. The two passengers seem to know each other very well, calling each other Colonel Abbas Nott and Miss Mary Debenham.

After the train arrived in Staple, Poirot crossed the Bosphorus and met his old friend, Mr. Booker, the director of the international bus company, at the Tokarian Hotel. When they were eating in a restaurant, the Americans at the next table caught Poirot's attention. He looks sixty or seventy years old, and his eyes always smell fierce and evil.

Stranger still, it seems that people all over the world choose to travel that night, and it is hard to get a ticket for luxury trains that have always been well stocked. Poirot, eager to return to England but unable to buy a ticket, got on the train with the help of Mr. Booker.

At noon the next day, Poirot, who came to the dining car, began to observe the passengers in the carriage according to his habit: a burly and dark-skinned Italian, a short and dignified Englishman like a servant, a big American like a traveling salesman, a Russian old lady and waiter, a couple of ambassadors from Hungary, and Colonel Abbas Nott and Miss Debenham.

At the other end of the carriage sat McQueen and his employer Rachel. After the dining car ended, the passengers left one after another. At this moment, Rachel suddenly got up. People have known Poirot's identity. He bluntly said that his life was threatened and wanted to hire Poirot to protect himself. Poirot was unmoved.

That night, the train arrived in Belgrade and loaded it into a carriage. Mr. Booker gave the box 1 to Poirot, and he transferred to the second-class car. Poirot accepted his kindness and moved into the box next to Rechet.

Late that night, Poirot was awakened by a loud cry in his sleep. At the same time, due to the snowstorm, the train was trapped in the snow between Winkovsky and Braud. Rachel died in his box in Zita Law. He was stabbed 12, but the door of the box was locked. With the deepening of the investigation, the case seems to be more complicated, and Poirot draws two completely different conclusions.
