"Why don't you go up the stairs?

Elle asked Gaius with a small neck.

"El, every pair of three years is on the third floor. And the school building is... three floors."

"... you mean on top of that... there's only the roof"

"Yes, the killer snuck up the stairs carrying the body, carefully unlocked the candlestick so as not to make a sound, and finally escaped to the roof."

"Hmm. But why was that a mistake?

"Well, didn't you tell Elle about the conversation you had with the guard?"

"Hmm. I'm not listening."

Gaius shrugged his shoulders and apologized for the bad looks.

"Sorry, sorry. Then you don't know the truth about the case."

"Well, that's good. What happened to the guards after that?

"Yeah. The guard checked each classroom with a lantern to see if there were any abnormalities, and after checking every pair for three years, he headed up the stairs... I went up the stairs."

"Um. So?

"The guard lit the door with a lantern. Then the candlestick key was unlocked. Usually there's a key that's supposed to be closed. So the guard felt unusual and opened the door."

"That's where you ran into the killer!?

"No, the guard tried to illuminate the edge of the roof with a lantern. Because I thought the guard's head might have had a suicide volunteer breaking into the roof..."

"Well, if a suicide candidate breaks into the roof, there's one thing to do, not just jump off the edge of the roof to the ground."

"Yes, that's why the guard only focused on the edge of the roof."

"Right! You mean the killer was lurking by the entrance and exit?

"Yeah. I think he was probably hiding in the shadow of the son carrying the body"

"Still couldn't find it?

"Perhaps the body was covered in a black cloth or something. Then I guess I can't help but see through the darkness."

"I see. The killer shrunk and hid in the shadow of the body..."

"Yes, and the guard, who decided there was no anomaly, left the roof..."

"Mm-hmm. Didn't the killer get away with it?

"No, there's no escape. Because the killer was trapped on the roof."

"Right! Did the guard lock the door when he left the roof!

"You're right, El. The killer spent the night with the body on the roof."

"Hmm. Is that what happened?"

"Oh, and when the teacher in charge of cleaning the roof opened the door in the morning, didn't he look at the gaps and talk from behind?

"Did you talk to him? Why not? Why don't we just run away?"

"You won't be able to move the body in the morning, will you? Why are there so many students who go to school so early in the morning?"

"So what are we going to do with him?

Gaius looked up to heaven for a moment and worked his imagination.

"Isn't this what you said?" What is covered with a black cloth over there is a sculpture I have made. Please don't touch me. '"
