Murder on the Express, Solved
ASolved recently was the murder case that occurred on the train from London bound for ○○.
The incident took place shortly after the train left London. A man, one of the passengers, was found dead in his seat.
Since the train was in motion and the number of people entering or leaving the carriage during the estimated time of the crime was limited, tension ran high among the passengers.
Several suspects emerged from among those in the same carriage as the victim.
The suspects are three:
The Victim's Wife — There were testimonies that she was arguing with the victim at the time of the incident, and it is said there were long-standing problems between the couple.
The Victim's Business Rival — Had financial troubles with the victim and possessed a strong motive.
The Conductor — It was discovered he had left his post where he should have been at the time of the incident. He testified he was attending to another passenger.
However, as the investigation progressed, it became clear that there were several contradictions in the initial testimonies.
Then, the detective who happened to be on the train, Guest, connected the slight inconsistencies left at the scene with the passengers' testimonies to uncover the truth of the case.
As a result of the police investigation, the case was solved. The suspect was arrested, and the train resumed normal operation.
It is said the detective themselves did not say much about the truth of the case.
Furthermore, the reporter who covered this case was also one of the passengers who was suddenly asked by the detective to cooperate in the investigation at the time.
