Apparently My Girlfriend Is a Murderer

Summary

I am a doctor.

One day, I come across a weird patient when I am on duty.

The first thing she says when she sees me isn't that she feels unwell somewhere. Instead, she says something hair-raising.

"Dr. Cantrell, your girlfriend is a murderer."

"What nonsense are you spouting?" I shoot back with widened eyes and shoot up from my chair.

I feel offended.

She calmly says, "She won't be home tonight because she needs to deal with the body. You will know whether what I say is true by tonight."
