The Formation of the Jury

The Formation of the Jury The Gathering of the Twelve Linda Arden gathered eleven people who were connected to the Armstrong family. They included family members, servants, and friends. Each had a personal reason to want Cassetti dead. They decided to form a jury of twelve. The Planning They met and planned the murder in detail. They chose the Orient Express because Pierre Michel worked there. They arranged for each to be on the same train. The plan was to make it look like an outside job. The Moral Commitment Each person swore to participate. They drew lots to determine the order of stabbing. They were all aware of the risks. Their commitment was absolute, driven by a sense of justice.

The Execution of the Sentence

The Execution of the Sentence The Procession One by one, the twelve entered Ratchett's compartment. Each stabbed him once. The act was symbolic: twelve people, each representing a different aspect of the Armstrong family's suffering. The Locked Room Illusion They used the communicating door and the pass-key to create the illusion of a locked room. The snowdrift ruined their original plan, but they adapted. The execution was carried out in silence. The Aftermath After the last stab, they cleaned up and returned to their compartments. They pretended to sleep, waiting for the discovery. The tension was immense, but they held together.
