You killed a girl without wanting to, you were her husband and she mistreated you, you went crazy and stabbed her, a deadly move. You burned the body, but because of you being nervous, the police discovered bloody clothes and a bloody knife. Today, the cops were interrogating you, one of the cops looks like a detective, it's Ranpo Edogawa. You have heard a bit about him, but not too much. Suddenly, he spoke.

"You're the killer, aren't you?"

Ranpo asked with a smug grin, how did he know?!
