"Oh? Young people seem to me to be very prejudiced. ”

[Martial Artist] smiled casually like an ordinary kind old man: "Why do you suddenly say such things? ”

"Before answering this question, do you mind if I ask the location of the room where the old man lives?"

Li Wu asked rhetorically.

"Wait, who are you? Why did you suddenly interrupt my reasoning? ”

The detective's cheeks puffed out in dissatisfaction, but there was no deterrent.

"It's just an ordinary resident, but I think everyone here should have the right to speak, right? This Miss Detective? ”

It seemed that the "famous detective" was just right, and the detective snorted: "Then listen to what you have to say first." ”

[Martial Artist] said the room where he was staying very cooperatively: "This inn doesn't have a room number...... To put it more conveniently, my room would have been on the far right of the second floor, near the courtyard, in other words, directly above Mr. Nagai's room. ”

"I see, then the puzzle is solved."

How do you make it up next?

Although Li Wu showed an unfathomable expression, of course, he didn't know why the [Martial Artist] was the murderer.

It's just a wave of pointing out purely based on the text.

"Hey, are you okay, classmate Li Wu?"

Hoshikawa Aoi whispered in his ear, and his breath was tickling.

"Don't worry, don't interrupt my train of thought."

Li Wu also replied in a low voice, and then looked at the detective: "Miss Detective just said that the door lock of the deceased's room has no traces of destruction from the outside, and the window is also locked. ”

"Combined with the testimony of the proprietress that the door was closed before she arrived, it was not someone who broke into the door and killed Mr. Nagai."

"You want to say it's a closed room murder case?"

The detective girl said casually.

"No, I think it was the murderer who disguised himself as a secret room after killing Mr. Nagai, and only you, old man, have the conditions to do such a thing."

"Oh? I didn't know I could do that. ”

[Martial Artist] rubbed his hands together and denied.

Li Wu continued: "I wonder if you still remember the situation in the room? Although I didn't look closely, I could remember that the victim's body was lying flat in the middle of the room, with a blow to the head and blood splattered on the walls and floors of the windows. ”

[Superpower Detective] put his hands on his chest and said: "And there are no bruises found on the hands, the nails are clean and tidy, and there are no foreign objects left, so it can be inferred that the deceased has died without a fight." In addition, there were several bamboo leaves left at the bottom of the victim's slippers, and it is possible that he had walked in this courtyard. ”

She hadn't been in the room for long, but she had observed so closely, no, should I say that this was really the result of observation?

"Do you still have the heart to observe corpses in the face of murder? I was so scared that I wanted to hide in my dear's arms. ”

The puppeteer pretentiously hugged the man's arm.

Li Wu ignored her, and continued: "There are two problems here, the first is that if Mr. Nagai is attacked from the front by the murderer with some kind of heavy object in the room, and he looks up and goes down, will the blood really show what we see? ”

"Miss Detective used the word 'well-dressed' when describing Mr. Nagai's outfit - if he was hit in the front, there would be at least a stain of blood on his clothes, right? And according to common sense, blood should accumulate under the victim's body, is it really possible to splash on the opposite wall? ”

"I mean Mr. Nagai's corpse...... Has the body been moved? ”

[Office workers] spoke tremblingly.

"That's what I'm speculating, and there's a second question, it's spring in April, and Miss Detective said that Mr. Nagai used to walk here, so would he really lock the window facing the courtyard and lock himself in his room?"

"Hmm, Li Wu is trying to say that the prisoner invaded the room through an open window, killed Mr. Nagai, locked the window, went out of the door and closed the door, creating the scene we saw?"

Very good, Hoshikawa-san, keep it up.

Although it is all nonsense, if there is a person who sings and harmonizes, the credibility will increase.

Li Wu raised his finger and shook it: "It's roughly correct, but I think there is something wrong in the order." ”

He pointed to the lower edge of the window in the room and said, "If the prisoner had entered the room through the window, it would have been impossible for Mr. Nagai not to resist, and whether or not there would be a big disturbance, at least not as Miss Detective said, there should be no marks left on his hands." ”

"And there's not a single adult hiding under the window here, so it's impossible for a prisoner to sneak up on Mr. Nagai's blind spot."

"You said in the wrong order, meaning that the killer killed the victim first and then entered the room?"

The detective girl concluded.

"That's right! And back to the topic, I think the only one who can do this is you, old man! ”

Li Wushu said categorically: "At that time, Mr. Nagai was probably enjoying the view of the courtyard by the window, as I said before, I think he had the window open, but even if he didn't, it doesn't matter, you can tie anything with a rope and hang it down, and gently knock on Mr. Nagai's window to attract attention." ”

"Naturally, the victim's first instinct is to poke his head out of the window to see who is playing a prank on him, and at this point, the old man you can take out the heavy object that has been prepared and is also tied tightly with a rope - something like a cement brick - and throw it down.

"Poor Mr. Nagai was killed on the spot by the accomplice of gravity, which is why he left a blood stain on the side near the window. Then, you can pull back the murder weapon, hide it, and then go to the courtyard, climb into Mr. Nagai's room, drag the body away from the window, and lock the window from the inside to create the appearance of a secret room. ”

This reasoning is not impeccable, at least it is also a level of pure TM, full of a lot of loopholes and strong words.

However, Li Wu is talking about the process of solving the problem according to the answer, and reasoning according to the real murderer, which gives him enough confidence.

And persuading others is sometimes really not much to do with logic.

So when he said so much with great momentum, everyone ...... Mainly refers to the [office worker] and the magical girl next to him, who really began to stare at the [martial artist] with suspicion.

"Wait a minute, do you think I haven't watched Mystery of the Tomb?"

[Superpower Detective] complained.

Li Wu's face remained unchanged: "I see, it seems that the old man is the criminal method you learned from speculative novels." ”

The old man who was accused of being the murderer smiled: "But regardless of whether the method you said is reasonable, what about the motive?" I didn't know Mr. Nagai before, why should I kill him? ”
