"I-I thought I told you, Professor. You're the servant, and I'm the master..."

"Yes, I heard you clearly."

"But what is this now then..."

"You've overlooked something."

Then the professor answered him with a smile colder than arctic frost.

"My curse is that every crime committed by my hand becomes a perfect crime."
