"Um, can I go to the bathroom?" Hinata Sou asked.

Inspector Megure glanced at Hinata Hajime, nodded, and then pointed to a policeman to follow Hinata Hajime. However, the policeman stopped at the door of the bathroom and waited for Hinata Hajime to come out before coming out together.

Arriving at the bathroom, Hinata Hajime looked around. After a moment he heard a click, the bathroom door opened, and a man with a pale face walked in.

"I'm sorry, I really can't stand it anymore." The man walked into the next cubicle in pain, and soon he started vomiting.

Hinata Hajime turned on the faucet and looked at himself in the mirror. Some tiny clues quickly connected together, and there was a sound of water splashing. After sorting out his thoughts, he saw the man staggering out of the cubicle. The man's eyes were wandering and he looked like he had just recovered from a serious illness.

Walking to another washbasin, the man washed his hands, then looked at Hinata Hajime.

"You seem very calm."

"Eh?" Hinata Hajime was stunned for a moment, "Me?"

"Yes." The man looked at Hinata Hajime in confusion. "From the time the owner's body was found until now, you're the only one among the six of us whose expression hasn't changed at all. I thought you came to the bathroom because you felt nauseous like me, but you just came to wash your hands?"

Hinata Hajime frowned slightly, "Do you really have to speculate at this time?"

"This is not just random speculation. After all, we have a murderer among us." The man looked a little tired, and he lowered his eyelids. "I don't want to waste any more time."

"You came to the bathroom but you didn't go to the toilet, you just washed your hands. What on earth are you doing here?"

Hinata Hajime looked at him, and after a moment he turned off the tap. "I just came to confirm one thing."

"Huh?" The man glanced at Hinata Hajime lazily. "Confirming something? Are you confirming evidence as a detective, or are you confirming whether the evidence has been destroyed as a murderer? These are two completely different forms, right, Mr. who knows the police?"

"Maybe it's the former." Hinata Hajime said in a calm voice.

The other party looked at Hinata Hajime in surprise, "Do you know who the murderer is?"

"I was just wondering how the murderer killed the store owner. If it was poison, where was the poison in the first place? Then I suddenly thought of something." Hinata Hajime looked at himself in the mirror. "I was thinking, what if the spilling of the soy sauce was an accident at the beginning, and it was not something the murderer had planned at all?"

Hinata Hajime murmured.

It is quite normal to knock something over in the middle of a meal. As long as you are close enough to the chef, you can touch him. After all, a polite chef will certainly not ignore a customer who knocks over something. However, before the murderer could knock over his own food, the friend next to him clumsily knocked over the soy sauce.

So he had to change his plan, stood up and helped his friend clean up the mess, and contacted the chef in the middle and poured poison on the chef's hands.

If you want the spilled items to affect the ingredients and force the owner to re-cut the ingredients, you can only do it at the position closest to the owner.

"Eh? Are you saying I'm the murderer?" The other party looked at Hinata Hajime strangely. "Since you judge like this, how do you think I put the poison? Everyone was watching. I didn't put anything weird in the chef's hand."

Hinata Sou thought for a moment, "Where are your gloves?"

"Gloves?"

"Your friend was surprised that your gloves disappeared. He must be so surprised because your gloves are very important. After all, they look like ordinary gloves. He would only be surprised that your gloves disappeared if you had specifically told him about it."

The man nodded. "That's right. Those are specially made gloves. I told him about them beforehand so he wouldn't damage them. But what does that matter?"

"So, the poison was on your finger, huh?"

Hinata Hajime said so.

The purpose of gloves is to isolate the poison on the fingers so as not to accidentally hurt other people. You just need to take off the gloves when you want to use them. This is something that can be done.

The other party was stunned for a moment, and then he sneered, "Don't be ridiculous, young man, wearing gloves means your fingers are poisonous? I'm just a germaphobe. I always wear gloves wherever I eat, and I have specially made gloves at home. It's not strange at all."

But is this really a cleanliness fetish?

I came to eat hand-kneaded sushi, but the sushi master didn't wear gloves. He could accept such sushi, but he couldn't accept his own hands touching the food.

Of course, even if he said that this was his own quirk, Hinata Hajime wouldn't be able to say anything. After all, some people do have all kinds of quirks, but...

Hinata Hajime clearly remembered one thing.

The man who knocked over the food was in a panic. At that moment, everyone around him looked over there, even Hinata Hajime looked over there, so he saw clearly that the gentleman standing next to him took off his gloves, and after helping the owner clean up the things, he carefully put the gloves back on.

Because this is not a strange thing to them, at most they think this person's cleanliness is really strange.

The owner dumped the ingredients that did not touch the ground directly into the trash can and then returned to the kitchen to prepare new ingredients.

Yes, the police haven't found out where the poison came from yet because they can't confirm when the ingredients were thrown into the trash can, or whether the poison on the owner's fingers was transferred to the ingredients, or the poison on the ingredients was transferred to his fingers.

"Your story is really interesting." The man exhaled, looking somewhat helpless and even a little tired. "But a story is just a story. No matter how logical it is, you have to find evidence. You said there was poison on my fingers, but the police have checked and there is no poison on my hands. Otherwise, you can just find the gloves."

"But unfortunately, because I was so disgusted, I threw the gloves away and flushed them down the toilet."

Yes, this is where it gets tricky.

Hinata's idea: When the body was found, this person rushed to the bathroom with a painful expression. Regardless of whether he was vomiting or not, he did rinse his gloves directly under the water during this time, and then washed his hands thoroughly in the sink. There was no trace of poison at all.

Without leaving any evidence.

Even if this person was the only one who had entered the restroom, it would be useless because there was no evidence that this person's gloves were poisonous, and there was no evidence that this person came to the restroom just to destroy evidence.

"You are indeed an unqualified detective." The man sighed, "But after listening to a good story, I feel my stomach is much better. My name is Matsushita Makoto, what's your name? A novelist who writes stories."

Hinata Hajime stared at the mirror in silence. After a moment, he spoke, "Hinata Hajime."

"Well, Mr. Hinata, goodbye. If you don't get out now, the police will come in." Matsushita Shin looked at his watch and said, "Bye."

"Wait a minute." Hinata Hajime turned his head calmly, "I didn't say I didn't have evidence."

Matsushita was stunned for a moment. He looked at Hinata Hajime and said, "Hey? Novelist, are you going to continue writing stories?"

"I've said it from the beginning," Hinata Hajime said, "I came to the bathroom just to confirm one thing, and to confirm that the evidence was not destroyed."

The man raised an eyebrow slightly, "Huh?"

Hinata Hajime paused for a moment, "You've been to the bathroom twice, so you should know better than me. The toilet inside doesn't flush automatically. Instead, you need to press the flush button to flush automatically."

"I just checked and there's no water on the button."

"This has nothing to do with whether there is water on the button..." Panasonic's voice suddenly stopped, and he widened his eyes slightly.

"It seems you've figured it out." Hinata Sou sighed, "You pressed the flush button with your poisoned finger when you rinsed your gloves, then went to the sink to wash your hands, and then went back outside without wiping off your fingerprints. And your fingerprints contain the same poison that killed the store owner."

He lowered his lips and trembled a little, "What does this have to do with me? If someone went into the bathroom first and rubbed poison on it..."

"But." Hinata Hajime interrupted his defense, "Except for you, no one has entered the bathroom, right?"

"You are the only one who can touch that button."

"It's you, the murderer who killed the store owner."

After staring at Hinata Hajime for three seconds, Matsushita turned his head lazily. He clasped one hand on the edge of the wash basin, his eyes full of fatigue. His face was pale, and he looked more and more like a patient who had just recovered from a serious illness. He said, "Ah, it seems that I was wrong. You are still a qualified detective, Mr. Hinata."

"Yes, I killed him."

"Why?"

"You ask me why?" Matsushita Shin turned to look at Hinata Hajime and laughed, "Mr. Hinata, why do you think a person kills? For money? For sex? Or for desire?"

"Unfortunately, I am neither."

Matsushita lowered his head and said, "I did this for revenge."

"He killed my girlfriend."

"Maybe you don't know, but I never intended to hide it from the beginning. The fingerprints on the buttons were actually clues I left behind." Matsushita really laughed.

"I know."

Matsushita was stunned for a moment, and he looked at Hinata Hajime with some surprise.

Hinata Hajime said, "I know you want to be caught."

For a planned murderer, Hinata Hajime didn't believe that he would forget to dispose of the bathroom button, but he just forgot.

At first, Hinata Hajime was not planning to go to the bathroom, but he heard Matsushita Makoto constantly saying that he wanted to vomit, wanted to leave, had stomachache, felt uncomfortable, and kept hinting at the bathroom, so Hinata Hajime decided to come over and take a look.

When he saw the button that had not been processed, Hinata Hajime realized that although this man killed the store owner, he wanted to be caught.

His purpose in killing the shop owner was not just revenge.

"Ah, really? We were found out. Mr. Hinata is an excellent detective." The smile on Matsushita's face disappeared. He lowered his head, and his expression became quite painful. "Do you still remember the arm in the refrigerator? The moment I saw the arm, I knew it was my girlfriend's."

"She had a scar on her wrist. When we were together, she told me that it was caused by her falling down when she was a child. The two cuts crossed on her wrist, like a butterfly spreading its wings."

Matsushita Makoto said calmly, "This is the first time since she disappeared that I have been so sure: she is dead."

Hinata Sou remembered that after vomiting, Matsushita Makoto kept looking at the refrigerator. Every time he looked at it, his face would get paler, but he couldn't help but keep looking over there. It seemed that it was not the human desire to commit suicide that was at work, but he couldn't help but want to take another look.

His vomiting was not fake. Due to the extreme disgust and painful physiological reaction, his stomach felt extremely uncomfortable.

Because the owner of that arm is his girlfriend.

"My girlfriend's name is Ishimaru Mai, she's just graduated from college, but she seems to be cursed by some strange men who keep pursuing her." Matsushita Makoto's eyes were filled with loneliness, "I met her because I helped her escape from a man's entanglement."

"We established a relationship very quickly. I was sure she was a very good girl, kind and gentle. Then she disappeared. Before she disappeared, I found harassing text messages from those men in her phone. They were still pestering Mai and even threatening her to be with them."

"I went to the police, thinking they were a strong suspect, but the police didn't find any information at all."

Matsushita really laughed, but this laugh was uglier than crying. "In fact, no one knew that I was Mai's boyfriend because Mai was afraid that those people would harass me. I was actually ready to make it public. I bought a ring and was ready to propose to her, but Mai just disappeared."

"So I went to investigate on my own, and then I found out that they were dealing with something behind the scenes. They didn't care about Mai's disappearance, and it was like they had become different people."

"In order to open this gap, I decided to kill one of them." Matsushita Shin looked at himself in the mirror, his eyes were full of bloodshot and his eye sockets turned red. He looked at himself in the mirror with gritted teeth, and finally a sneer appeared between his teeth.

“It seems that I made the right decision.”

Even Matsushita Makoto did not expect to see Ishimaru Mai's arm in this person's refrigerator.

Those people really killed Ishimaru Mai and even dismembered her body and stuffed it into the refrigerator.

Perverted and disgusting bastard!

"My mission is accomplished. Now the police will follow this clue and investigate further." Matsushita lowered his head. "It would be great if that guy wasn't poisoned to death. The dosage hasn't been determined yet. If he's still alive, we can get more clues from him."

“What a pity.”

Hinata Sou stood still, "Have you thought of any other solution?"

"There's no need to worry about this anymore. After all, we've already done what needs to be done." Matsushita smiled. "Goodbye, Detective."

"I'm not a detective."

"Really?" Matsushita Makoto slowly raised his hand. Outside the bathroom, the police pointed Kimura at him. He nodded at Hinata Hajime, then obediently turned around and was handcuffed. The police walked past Hinata Hajime to collect evidence.

Officer Megure thanked Hinata Hajime, but Hinata Hajime politely declined and left with the police.

Outside the restaurant, he saw Matsushita, handcuffed, being stuffed into a police car. At the last moment, the man looked outside, but it was unclear what he was looking at.

With a ding-dong sound, Hinata Hajime's cell phone rang.

Seeing Nanami Chiaki's face, Hinata Hajime walked to the side and then put the phone to his ear as if he was answering a phone call.

"Hinata-kun, I found out." Chiaki Nanami's voice was serious.

"Okay." Hinata Sou lowered his head, "There's no one around, you can talk."

Nanami Chiaki was silent for three seconds before she spoke, "The girl who was pursued on the street was named Ishimaru Mai. She is now missing. Moreover, she disappeared on the night I called the police. As for those who pursued her, two of them are dead."

"Including this shop owner, that makes three."

Hinata Hajime's hand tightened, "Did those people take any action after the girl disappeared?"

"This is the strangest thing." Nanami Chiaki's voice was full of sadness. "They were so passionate about pursuing that girl that day, but now that she is missing, they don't care at all. In this case, it is very likely that those people caused the girl to disappear."

"If I had been more careful, this wouldn't have happened."

"Don't think like that, Nanami." Hinata Hajime leaned against the wall, looking up at the sky. "After all, you didn't know this would happen, and you called the police immediately after you found out she might be injured. You've done everything you should have done. Don't be too hard on yourself."

Nanami Chiaki lowered her head, looking a little depressed, "I understand, Hinata-kun."

"Then Nanami, why did those two people die?" Hinata Hajime changed the subject.

"According to the police records, they died in a fight." Nanami Chiaki perked up and began to confirm the information she had seen before. "Yes, it was a fight. Moreover, they attacked each other in the fight. In the end, both of them were injured and died in the alley."

This is very strange, because these two people are not small thugs. They can even be said to be relatively successful people among the younger generation. They have sufficient financial resources and good family education. However, they would die in a fight in the alley.

Hinata frowned, "Killing each other? Why?"

"I don't know." Nanami Chiaki said, "Hinata-kun, I'm not in my physical form now, so there are many things I can't do. I can only ask you. I think it's necessary to go to the homes of those two people to take a look. Their fighting is unusual. There must be something that made them attack each other so fiercely."

"How do I get in?"

"Pretend to be a police officer." Nanami Chiaki showed the picture warrior in her hand to Hinata Sou, "Although I am very sorry, I think it is easier to get clues as a police officer investigating the case at this stage, so I put Hinata-kun's information in the contract of the special profession without authorization, and it will not be discovered in a short time."

Hinata Hajime was stunned for a moment, "Let me pretend to be a policeman?"

"Hinata-kun will be fine!" Nanami Chiaki said, "By the way, who committed the murder just now? Has Hinata-kun found the murderer?"

"Ah." Hinata Hajime smiled bitterly, "He's Ishimaru Mai's boyfriend."

Nanami Chiaki was stunned for a moment, and after a moment she whispered, "Is it that...Matsushita-kun?"

In order to confirm Mai Ishimaru's identity, Chiaki Nanami hacked into her communication records and retrieved a lot of content from her mobile phone number. Among them, the person with the most communication content was a person named Matsushita.

In those text messages, Chiaki Nanami could feel full of love.

They are in love.

No one can dispute this.
