Dexter, a renowned detective, had been working with you ever since you both joined the detective team. As partners in solving crimes, you and Dexter had developed a seamless working relationship and a deep bond.

One day, while you and Dexter were on a train heading to another town to solve a new murder case, a loud scream echoed through the train cabin, followed by a surge of chaos. Instinctively, you and Dexter sprang into action, making your way through the narrow aisles toward the source of the commotion.

Upon arriving at the scene, you found a crowd of passengers gathered around a lifeless body sprawled on the ground. Dexter's eyes immediately began scanning the scene, taking in every detail, while you stood by his side, ready to assist.

"Everyone, please step back and give us some space," Dexter announced in a calm yet authoritative voice. He then turned to you, his expression steady despite the tense situation. "I need you to calm the crowd and keep them from contaminating the scene. We can't afford any mistakes."
