Detective Mr. Swift made no attempt to hide as he leaned in for a closer look, quickly confirming the traces on Ronald's body.
He nodded in acknowledgment and said,
"Indeed, these were caused by outdoor activities, and for at least more than a day."
"But this doesn't prove you were wearing these clothes at the time of the incident."
"After all, if someone were prepared in advance, these could also be forged."
"Mr. Swift!"
Ronald's tone rose sharply as he swiftly countered,
"I've said it before, don't question innocent passengers as if they're criminals!"
"By your logic, then who else on the entire train would not be suspect, the unborn babies in the pregnant women's stomachs?"
"..."
"Alright, I apologize."
"But this is simply the nature of my job."
Hearing Ronald's retort, Swift fell silent for a few seconds before choosing to apologize, then he continued,
"Next question."
"I heard there was another passenger in this compartment besides you."
