Wednesday, January 10th, evening, Garden House, Garden Bedroom.

The TV was on, Yuan Zi pouted and lay on the bed using the laptop to browse the web, thinking about the problem of New Year's gifts, and suddenly found a target, which said to give it to a friend, so that friends can think of it every day, click on it and decide that it is it, so I took the phone on the bedside and called Mei Daizi's mobile phone, and asked Mei Daizi to accompany her to pottery class on Saturday morning.

"Morning?" asked Meidaiko, who was working at Mei Dai's restaurant, "Then can I not go?"

"What do you say?" said Sonoko, "remember to bring the tuition tomorrow, and Yamazaki will come too, right? ”

"You guys, Ran, right?" asked Midako, "She agreed to take such a boring and expensive class?"

"What," said Yuanzi, "don't worry, Lan will definitely go." ”

"Definitely, it can't be the case that I went to Lan and Lan went to I, right?" Mei Daizi asked with a smile, "Are you planning to be a middleman and eat all together?"

"How is that possible?" said the gardener, sneering dryly.

"Really?" asked Midaiko, "Why do I think you're lying?"

"Well," said the garden, "Ran will definitely go, and definitely not because you went. Then he smiled a little excitedly, "By the way, she is for her Kudo, in order to give Kudo a New Year's gift, that's it." Then he smiled, "I think you and Yamazaki can make one by yourself, and then give it to each other as a gift." ”

"It's been there for a long time. Mei Daizi said, "Forget it, just go, but first say okay, I'll make one." ”

"Of course, I'll make one. Yuan Zi said, and then complained, "It's all my father's fault, if it weren't for the fact that I didn't have to give a New Year's gift in a hurry, I wouldn't have gone to such a boring class." ”

"Then settle the score. Mei Daiko smiled.

"Of course, I must let him lose a few pounds of fat, and I should help him lose weight. Yuan Zi gritted his teeth and said.

"Heh......" Mei Daiko laughed for a moment and then said, "Okay, I'm still working, don't talk about it, things will be as you said, I'll hang up the phone." ”

"Okay, see you tomorrow. Yuan Zi said, hung up the phone and smiled, "Get one, then another." After saying that, he called Lan again and asked Lan to accompany her to pottery class on Saturday morning.

"Pottery class, what are you going to do with that?" asked Lan, who was sitting on the bed reviewing her homework.

"You've sent nothing but a greeting card to that guy this year, have you?" asked Sonoko rhetorically.

"That guy, you mean Shinichi?" Ran asked.

"It's the guy who hasn't seen anyone all day. "That guy is barely a handsome guy......"

"It's okay, it's okay. Lan was a little embarrassed.

"It's not like you haven't seen Bond's movies, with that guy's nosy personality, you're bound to meet a lot of women, and it's bad if he's pestered by a woman from an unknown source. Yuan Zi covered his mouth and snickered, you won't take the bait now.

"This ......" Lan began to make up for it, and there were countless opponents for a while.

"Now there's an opportunity to put it in front of you, and you can make a teacup for that guy with your own hands, so that he will think of you whenever he drinks water. Yuan Zi covered his mouth and snickered, "Man drinks at least eight glasses of water every day, that is, he thinks about you eight times a day." ”

"Saturday, right? Okay, I'll go. Lan said categorically.

"Well, remember to bring the tuition to school tomorrow. Yuan Zi smiled, and then reported the amount, and at the same time thought to himself, I knew that I would get this side first.

"Okay, then we'll see you tomorrow. Lan said, and hung up the phone. ……

Thursday, January 11, afternoon, Maori Detective Agency.

Yamazaki came over and found Mori at home and told him about the murder weapon in the arcade incident.

"Uh," Maori blinked, "you mean the murder weapon was actually in the intestines?"

"This is just my guess, I just wanted you to remind the Dusk Police Department, uncle. Yamazaki said, " I speculate that the whole incident is like this, the murderer gave the deceased an enteric-coated capsule that does not melt in the stomach at some point before, and this enteric-coated capsule has a small needle with high-purity tetrodotoxin, and when the deceased sits on a game chair in the afternoon, the enteric-coated capsule enters the intestines and melts, although many times it will not be a problem to swallow sharp small things, but when playing that fighting game, you need to punch and kick, which will drive the abdominal muscles to move, and then accumulate the intestines, so that the small needle will definitely become a deadly murder weapon。 ”

Maori asked, "But in that case, why didn't the medical examiner check it out?"

"Let the forensic doctor be negligent, this is the purpose of the murderer's trap. "The responsibility of the medical examiner is to find out the cause of death of the deceased, the time of death, and so on from the body of the deceased. The time of death of the deceased in this incident is very obvious and does not need to be investigated at all. ”

"Not bad. "Dead time is halfway through the game." ”

"And the cause of death, the body that died of the poison of the pufferfish, the forensic doctor must have seen a lot, and there is a guess that the deceased will soon be able to find out that the deceased died of the puffer fish poison, plus the eye of the needle at the root of the palm of the body, the cause of death will also come out. "The forensic doctor who has completed the task will not be interested in a body, and in this way, the body of the deceased will no longer be autopsied." ”

"Yes, yes, that makes sense. Maori said, and then asked, "But what about the eye of the needle? Is there tetrodotoxin on it, the forensic doctor can't be mistaken." ”

Yamazaki said: "There is tetrodotoxin on it, I guess the murderer caught a pufferfish, and then pricked its organs with a needle, so that the needle is poisoned and then the deceased, so that although the deceased will not die immediately, there is tetrodotoxin in the eye of the needle, and after the deceased is killed, the forensic doctor will naturally detect high-purity tetrodotoxin from his blood." Perhaps the murderer planned the murder after he had a puffer fish and then thought that he could get a high-purity tetrodotoxin from somewhere. ”

"Well, it's possible. Maori asked, "And who do you think the murderer is?"

"I don't know, it's up to the police to investigate. "Who the deceased was with before, who he had lunch with at noon, and who stole high-purity tetrodotoxin, the combined answers to these three points are enough for prosecutors to prosecute." ”

"Okay, I'm going to the Metropolitan Police Department to find the Twilight Police Department. Maori ran away. ……

A day later, the search for the arcade ended, and the police did not find the needle. The medical examiner found a small needle in the intestines of the deceased and determined that it was the real murder weapon.

Another day later, the police discover that Kengo Oto, aka Julius Caesar of Rice Flower Town, has something suspicious about him and that his income as a gamer does not satisfy his life.

Another day later, the police opened Kengo Oto's safe deposit box in the bank according to a key to a bank safe deposit box of Kengo Oto, and found that there were several indecent photos of women taken in the public restroom, as well as a list with contact information.

Another day later, the police found that one of the women in the photo had lost contact, and after investigation, it was discovered that it was Shisui Takaho, the sister of Lucas in Kakutocho, and Shimizu Takaho quit her job as a magazine writer, her sister quit her job at a convenience store, and the two went to Germany.

The police became suspicious of Zhishui Gaobao and immediately launched a further investigation, which revealed that Zhishui Gaobao had published an article about high-purity tetrodotoxin.

The police visited the institutions mentioned in the article, but were told that no high-purity tetrodotoxin had been lost. Since no one has reported the loss of high-purity tetrodotoxin, the police have become suspicious of the insiders of the agency.

Two weeks later, the police investigated at a café in the town of Kakuto that on the afternoon of the day Kengo Oto was killed, Shimizu and Kengo Oto were there drinking drinks and chatting about professional gamers, and Shimizu Takaho also said that he would write an article for Kengo Oto.

A month later, the police found that some of the people in the institutions mentioned in the article did not match their assets, and after further investigation, it was found that they were secretly selling the refined high-purity tetrodotoxin.

After interrogation of the men, the police learned that Shisui Gaobao had 10 grams of high-purity tetrodotoxin on his hands, which he extorted from them after discovering their secret.

The police immediately issued a wanted notice for Zhishui Gaobao and negotiated with the German police, but they did not find Zhishui Gaobao, and he and her sister took advantage of the convenience of the Schengen area to go to other countries.

Half a year later, the police received a notification from the Haneda Airport police that the wanted criminal Shisui Takasu had surrendered.

According to Shimizu Takaho, his sister is an introvert and doesn't tell him after being blackmailed by Kengo Oto, but just works hard to save money to cope with the blackmail, and as a result, she faints from exhaustion at work.

The doctor said that it was due to malnutrition and poor mood, and that if it was not treated properly, it might lead to blindness and organ failure.

Shimizu Takaho asked his sister about being blackmailed by Kengo Oto, so he made up his mind to kill him. So I approached Kengo Oto as a magazine writer, played video games with him, and eventually became friends.

A few days before the crime, the two of them went fishing, and Shimizu Takaho caught a pufferfish, so he thought of a murder plan and implemented it.

At noon before the incident, Shisui Takasu and Oto Kengo had lunch together, but they drank too much wine and ate less, and before the end, they pricked Shimizu Takasu with a needle that had pierced a puffer fish while Oto Kengo was drinking, and made Oto Kengo take an enteric-coated capsule containing a poisonous needle. Shisui Takabao's sister used enteric-coated capsules, and he asked the doctor and knew that when eating certain foods, the enteric-coated capsules would enter the intestines about two hours later.

After the meal, Shimizu Takaho took Kengo Oto to a nearby coffee shop to sober up and chat, talking about helping Kengo Oto write a magazine article. And the poison needle in his hand, Zhishui Gaobao threw it into the passing river on the way.

After Shimizu Takaho estimated that the time was about the same, the two took a taxi to the game hall, and just like that, Kengo Oto was killed by a poisonous needle in his intestine while playing a game.

After returning home, Shisui took his sister to Germany, and then went to the United Kingdom to treat his sister after passing through other countries, and when his sister got better, he returned to Hokkaido together, and arranged for his sister to continue treatment at Hokkaido Ishikari General Hospital in the Good Mood Water Department, and he returned to Tokyo to surrender to the police.

Shimizu Takaho only turned himself in for the killing of Kengo Oto, using the poisonous needle in the creek as evidence. The police had no evidence on the issue and had to give up because they had no evidence of the needle containing high-purity tetrodotoxin, which they had bought from the underground market, and did not answer the question of extorting 10 grams of high-purity tetrodotoxin.

Later, Zhishui Gaobao surrendered for homicide and was sentenced to three years. ……
