The police car quickly drove into the campus of Lihai University and Middle School, and the yellow cordon and crowds of onlookers surrounded the entrance of the gymnasium. Members of the Discipline Committee from the middle school to the university department and the members of the Kaiwon Festival Executive Committee worked hard to maintain order at the scene, and even had to form a human wall with open hands to prevent people from approaching. The Kanagawa Prefectural Police Department Yokozo Shigego struggled through the crowd and strode to the haunted house where the lights had been turned on.

"The deceased is here?" The Henggou Police Department shivered as soon as he entered the door, and frowned and looked at the machine that had turned off the dry ice blasting but was still bubbling cold, "It's just a school festival for middle school students, it's really luxurious." He shook his head and walked over to Chen's body at the door of the break room, led by his assistant.

Sasabe's body was stiff, his arms were raised above his head in a strange position, and his body was spasmed back in the shape of a bow, indicating that he had undergone violent convulsions before he died. His eyeballs bulged out like light bulbs, his facial expression was completely distorted, and half of his face near the corners of his mouth was even swollen like bread.

The Henggou Police Department stretched out a white-gloved finger and pressed the deceased's face, and then pulled the corpse's chin, making the already strict face even more terrifying.

"Has the deceased been identified?"

"Yes, it has been identified. The Kawaida Police Department, who had black hair beside him, took out a small notebook on his chest and replied to him, "The deceased's name is Kyoichi Sasabe, 21 years old, and he is a student of the Faculty of Economics of Lihai University. ”

"The students of this school? There's a lot of potential for internal crime. But it's the time of the school festival.,There are almost tens of thousands of tourists and students coming and going.,Do you want to lock the school off......" The Henggou Police Department crossed its arms and breathed out as if worried, "Anyway, let's call the first discoverer first." ”

The Kawaida Police Department nodded and waved his hand to a few people not far from the corpse. Nao, Nioh, and the other two silently glanced at each other, and together they walked over to the corpse's location.

"Are you all the first discoverers?" the Henggou Police Department looked at several people with different expressions from head to toe, "Bone girl, bloodstained people, and two children......" He squinted his eyes and approached Nao and Nioh, Yan Sù's face squeezed out an interesting smile, "The other two don't talk about it for the time being, you two are just junior high school students, and you don't even have a little scared expression when you see this kind of incident." ”

Nao looked at him expressionlessly, although his face was a little pale, but he didn't flinch in the slightest. Nioh stood with his hands in his trouser pockets hunched to the side, but his eyes turned cold and alternate between Yokozo and Nao's faces.

Yokozo looked straight into Nao's eyes and reached out his hand to compare her feet.

"But compared to that, can you tell me where the blood on your shoes came from?"

With the sound of the horizontal ditch, Chuanzi, who was standing behind him, suddenly tensed. She looked worriedly at the two facing each other, as if she wanted to say something, but was stopped by Nioh's eyes, who seemed to have realized something.

"What do you think?" Nao looked at Yokomizo's distrustful face, and her golden green eyes narrowed coldly, "As a police officer, shouldn't you interrogate the suspect after finding out the cause and time of death of the deceased? ”

"The real criminal?" said Yokozo, grinning, "although I don't quite believe that such a young girl could be a criminal, but the mark on the left side of the deceased's face is exactly the same as the pattern on the upper of your shoes, little girl! I just observed that the deceased had been hit the face and back of the head, and that the deceased's face had the same pattern as your shoes, and there were blood stains on your shoes—can you explain this phenomenon?"

"That's right, I used to hit him. The wound on his face was inflicted on me, and he used to vomit because I hit him in the stomach. Nao shook her hair, her pale face turning bloody, "But I don't think an adult who can do karate will be beaten to death by my adjusted punches and kicks - even if I have the ability." ”

"Poof!" Nioh said with a smirk of unknown meaning.

"Then you don't admit it?" Henggou straightened up and sneered, "The cause of death of the deceased was the death of the head after being violently hit, and according to the condition of the corpse, the time of death was about three hours ago. Where are you around nine o'clock in the morning?"

"-Three hours ago?That can't be!!"

But before Nao could speak, Kawako behind her screamed, "We met Sasabe around eleven o'clock, and he just came to the simulation store around ten o'clock!"

"Besides, I saw this little girl and this boy when they entered 'Foggy London', and before that Sasabe had come out of the lounge in good shape. The tall "Jack the Ripper" touched his head and picked up Chuanzi's words.

The face of the Henggou Police Department was dull for a moment, but before he could react, another voice sounded behind him-

"If the cause of death was death by beating, then it was true that the time of death was three hours ago, but according to the death of the corpse and the testimony of several others, the cause of death of the deceased was not so. ”

The boy in the dark blue uniform looked down at Sasabe's corpse, and the red armband on the crook of his arm stood out in the light. He turned his head to look at the Henggou Police Department, whose face had turned black, and continued.

"The deceased's limbs spasms and muscles in his arms tense suggest that he had violent convulsions before his death, which could have been a condition such as epilepsy if it had occurred naturally, but his face showed an unnatural smile, his body was arched, and his body was already stiff...... According to my inference, the deceased was poisoned - presumably a poison similar to an alkaloid. ”

"Boy, where did you come from?" Henggou twitched the corners of his eyes and asked the boy in a vicious voice.

"It's rude. The boy pushed his glasses, and the reflective lenses made it difficult to see his expression, "I'm Yanagi, a member of the executive committee of this Kaiwon Festival, and I'm also a member of the Discipline Committee of the Middle Ministry. I have been appointed by the President to assist you in the police investigation. ”

"Police, police department...... Kawaida police department supplement ran over in a panic, holding a thin notebook in his hand, "This is the register that this Yagyu classmate found just now, recording the names and entry times of the people who entered the haunted house from this morning to noon. ”

"Registers, there's that kind of thing?"

Yokozo grabbed the notebook in Kawaida's hand and opened it to the page with the person's name written on it. He looked at it, and the face that had just twitched the corners of his eyes tightened again. He raised his head and cast a solemn gaze on Nao and Nioh, who had a somewhat contemptuous expression.

"You two, what's your name?"

"Saotome Nao. ”

"Poof, Nioh Masaharu. ”

The Henggou Police Department snapped the register together and let out a sigh of relief.

"I'm sorry, but I was arbitrary. He frowned, "But that doesn't mean that your suspicion has been ruled out!Kawaida, go and ask the people in the forensic department, and bring all the relevant people according to the real time of death of the deceased!"

"Ahh

After this episode, everyone involved in the case is called to the lounge of the haunted house, and the real murderer investigation finally begins.

The lounge inside the haunted house was almost full, and the incandescent lights reflected the pale faces sitting around the tables. Sasabe's death left a deep impression on everyone present, and even Nao, who had seen all kinds of injuries in the dojo, had never seen such a terrifying sight. Until now, Sasabe's face echoed in her mind—alternating between the fierceness of the fight and the fierceness of the post-death period, and finally formed a pair of wide-open, empty eyes. She shook her arms hard, and the sudden relaxation followed by fear made her tremble.

"Are you alright?"

Nioh handed her a steaming pot of green tea, and the young man's voice was full of exhaustion and worry as he smiled uninhibitedly. Nao nodded, took the can he handed him and held it in the palm of his hand. The warmth of the aluminium skin penetrated her veins, dissolving the ice in her eyes.

"I'm so sorry that you were invited to visit the Kaiwon Festival and this kind of thing happened......" Nioh sighed and looked at her complicatedly, "I'm scared, aren't I? ”

"Anyway, it's just a murder. Nao picked up the green tea that had been opened by Nioh and took a sip and tugged at the corners of his mouth, "It's just the first time I've seen this kind of miserable corpse, and I'm a little maladapted." ”

"'just' a killing?" Nioh wried and furrowed his eyebrows, "What kind of environment do you usually live in, and the murder is still described as 'just'!"

"Ah, there's a workaholic guardian at home. Nao said lightly, "What killings, bombs, robberies...... Researching any photos and materials of events you can think of is a daily part of my daily routine, but this is the first time I've seen a real body. ”

"It's not easy for you, you're such a good boy!"

Nioh looked at Nao, who seemed to have recovered from her original state, and reached out his palm to pat the top of her head, rubbing her meticulously combed head, and just as Nao was about to give the other a roll of the eyes, the young man who had been standing there since the beginning and had not been noticed by the two of them opened his mouth at this time, and his dry, sunny voice drew their attention.

"It turns out that your family is a police officer, no wonder ......"

"No wonder, no wonder what?" Nao looked at him when he heard this, not knowing why.

"It seems that you have forgotten about jì, so let me reintroduce it. The boy in the dark blue uniform pushed his glasses, "Below is Yagyu Hirus, the first year of the middle school affiliated to Tatsukai University, and my father opened a clinic in Kanagawa called ......"

"Yagyu Clinic!" Nao subconsciously picked up his words, "It turns out that you are the ...... at that time"

"That's right, it's me. Liu Sheng smiled slightly, "Last case, was the investigation still smooth?"

"Ah...... OK. "Nao is a little weak for some reason.

"Then if there is anyone who can help next time, please be sure to inform me again. Yanagi smiled politely at her as if he didn't care about Nao's expression, and his glasses covered his eyes as if they were covered with a layer of fog, "Don't look at me like this, I'm also quite interested in that case." ”

Nao nodded at him and continued to sip the green tea in his hand one by one. Although she couldn't see anything on her face, her heart was already surging. The clumsy acting skills she revealed when she helped Matsuda Jinpei investigate at that time were really seen through......

Nioh pulled up the pigtail on his shoulder and gently swept the corners of his mouth, looked at Nao, who bowed his head and was silent, and then looked at Yagyu, who was smiling, and his green eyes flowed with a hint of interest. It seems that in the back and forth between the two just now, he instantly became extremely interested in this member of the student council, who was already quite famous even though he was in the same grade as him.

Just as Nao slowly sipped and drank the can of green tea to two-thirds, the Henggou Police Department finally strode into the lounge.

"Presumably everyone already understands what happened just now, so I won't talk nonsense. Henggou threw the paper clip containing the preliminary autopsy data on the table, and scanned the crowd sternly with his hands on the edge of the table, "I want to know where you work in this mock shop, and what you have done during the period from eleven to half past eleven." ”

Everyone looked at each other, and their expressions of surprise were overflowing.

"Officer, are you suspicious of us?" a man who looked extremely sven pushed his glasses, "Although Sasabe-kun was killed in our mock shop, can't you rule out the □possibility of an outside criminal?"

"Oh, what do you mean, do you have any clues?" the Henggou Police Department glanced at him mockingly, holding up a blue-covered notebook, "Your register is very clear, the only people who have been in and out of the haunted house in the hour before and after the crime are a few students over there, and the rest are only you staff." Tell me, is there any other possibility?"

"How do you ...... like this?"

Kawako muttered, and the rest of the people looked at each other in disbelief.

"I see...... Then I'll do it first. ”

The Sven man swept his eyes over the faces of the few people present and sighed softly. Nao keenly noticed that the fingers of his right hand pushing his glasses bent unnaturally as he said these words. She sat up straight and narrowed her eyes, only to see Nioh beside her doing the same as her.

"I'm Nakamura Lehei, the head of the Lihai University Drama Club, and this simulation store is also planned and opened by our Drama Club. Sven, a man named Nakamura, began, "Because I am in charge of the booth this time, the position is not fixed. I was outside the store all morning in charge, and around eleven o'clock it was time for us to change shifts for lunch, so I went back to the lounge to get my lunch box, and then I was eating lunch on the benches outside the gymnasium. As for the time...... yes, around 11:20. Because our lunch time at noon was only half an hour, I remember it well when I went out. ”

"Are there any witnesses?" asked Kawaida Police Department Supplement as he wrote it down in his notebook.

"I was probably seen by the person in charge of checking in at the door, and there were a lot of people outside the gymnasium at the time. ”

"Really...... Then the alibi should be well confirmed. Henggou nodded, "Also, when was the last time you saw the dead?"

"Sasabe-kun hasn't seen him since he arrived at the simulation store around ten o'clock. Nakamura shrugged, "He's always been reluctant to be restrained, and this kind of activity has always come and go at will." ”

"Is that all" Kawaida looked up at Nakamura, and after receiving an affirmative look, he turned his gaze to the others, "Then ...... next?"

"I'll do it. ”

This time it was a tall man who played "Jack the Ripper", named Saruto Eiji, who was in charge of the scenes and props in the drama club. He stood up almost two meters, and after taking off his costume, he could see his big arms. His testimony was much simpler, and the process was consistent with what Nao and the others had experienced.

He had been in the scene of "London in the Fog" before the crime as Jack the Ripper, and went to the break room once because of an upset stomach on the way to a conflict between Nao and Sasabe. Ten minutes later, he felt unwell again, and on the way back to the lounge, he ran into Nao and the others, so he went to the lounge with them, and happened to see the dead Sasabe. The person who can prove that he is right is the last person involved in this incident.

As for this last person involved, it's called Tanaka Kusata and is the screenwriter of the club.

He has a clean face full of sunshine, but the expression between his eyebrows is mixed with a little inferiority and weakness. According to him, he was the one in charge of playing the kappa in the haunted house "Hyakki Night Walk" area, and he felt very frustrated because he couldn't frighten the visitors, and when he went back to the lounge to calm down, he met Saruto, who was upset by his stomach, and was comforted by Saruto and returned to his post. But before leaving, he met Sasabe, who had returned to the lounge with a scar.

"Senpai was angry, so I quickly got out of the lounge and was still drinking while I left. Tanaka Kusata said with some embarrassment, "Because Sasabe's seniors don't get along very well, I'm a little ......."

"I said, why don't you come and call me!" Saruto patted him on the shoulder, "How many times have I said it, every time I was called by that Sasabe to come to me, no matter how bad I am, I won't let you be bullied by him!"

"Yes, I'm sorry," Tanaka smiled shyly and scratched the back of his head, "but at that time, you were still in the bathroom, and I think since you ran out of the lounge, you should run to the post in one go...... Hehe. ”

"Isn't the bathroom in the lounge?" Nao's eyes lit up and he opened his mouth suddenly.

"Ah, yes, the bathroom is about a few meters away from the lounge. Tanaka pointed out the door, "Since our booth was built against the wall, we brought in a small restroom that was originally next to the wall of the gymnasium." ”

"That's ......"

Nao nodded, gently nibbling the fingertips of his thumb, and Yanagi on the side also pushed his glasses thoughtfully. Nioh glanced at their expressions and raised his right hand lazily.

"Police, is the wound on the back of the head also investigated?" his eyes swept around the few people present, and the corners of his mouth curled, "After all, the 'only' wound on the back of the head of unknown origin is ......"

The Henggou Police Department looked at him for a while, and a smiling smile seemed to appear on Yan's face. He turned his head and slapped his palm on the table, and shouted with great momentum: "Then now, please remember whether the deceased had a grudge against anyone, whether anyone had a conflict with him!"

"If you want to talk about ......revenge," Nakamura, the president of the drama club, set his eyes on Kawako, who had not spoken, "Officer, there is another person who has not explained her alibi, and this person ...... Probably the person who is most likely to have a conflict with Sasabe-kun. ”

While Nakamura said these words, Nao carefully observed the expressions of several people from under the sea, and finally lowered his head and gently curled the corners of his mouth in the dark. At the same time, the young man in the blue uniform also silently recited such a sentence in his heart-

(Seemingly, the relationship is a bit complicated.) ）
