You decide to question the other passengers in the dining car about the victim. You approach a group of three individuals sitting together at a nearby table. They seem engrossed in conversation but pause as you approach.

"Excuse me," you say, "I couldn't help but notice the commotion earlier. Did any of you see or hear anything suspicious?"

The first passenger, a middle-aged woman with a pearl necklace, looks at you nervously. "I-I'm afraid I didn't see anything out of the ordinary. I was engrossed in my book."

The second passenger, a distinguished-looking gentleman with a monocle, raises an eyebrow. "I'm afraid I was too preoccupied with my meal to notice anything unusual. Quite a shame, really."

The third passenger, a young man in a sharp suit, shrugs. "I was sitting at the bar, minding my own business. Didn't see or hear a thing."

What would you like to do next?

1. Press the middle-aged woman for more information.

2. Ask the distinguished gentleman about his whereabouts during the incident.

3. Inquire further with the young man at the bar.
