Knock knock.

Is that someone at the door? You weren't expecting visitors. You get up from the couch, cautiously walking over to the front door. You open it just a peek, to see who it is.

"Hello, ma'am. May I ask you just a few questions?"

He holds up a police badge, with the word 'detective' printed on it, along with his name, 'Shikanoin Heizou'.

"I'm with the police department."

His voice is stern but polite. You can't help but wonder what this is all about.
