Led by the head chef, the group arrived at the kitchen waste disposal area, where several large garbage bins were filled with ordinary leftover food.
On the other side, there was only one basket, and the basket contained only a few scattered items.
The head chef pointed to the basket and said, "That's where the scraps from processing pufferfish are kept."
He then picked up a notebook from the table and handed it to Inspector Megure: "This is a record. To prevent any mistakes, it contains information such as the processing time for each pufferfish."
The head chef's habit made a significant contribution to solving the mystery of the case; although the record was only brief, the team obtained crucial information.
Takagi put on rubber gloves and began to identify the ingredients with the head chef. After careful examination, they discovered that all the toxic substances in the pufferfish were contained there.
Because only one item was sold today, and these scraps are processed every day, this greatly helps in solving cases and significantly reduces the workload.
Pufferfish muscle does not contain toxins, so generally speaking, it is not dangerous if handled properly.
The most poisonous parts of a pufferfish are its ovaries and liver, followed by its kidneys, blood, eyes, gills, and skin. In addition, the size of the toxin is also related to the growth cycle, but we will not discuss these for now.
Next, Takagi checked the purchase records and the remaining ingredients with the head chef to ensure that there were no oversights.
Therefore, the restaurant was temporarily cleared of suspicion. After the restaurant was cleared of suspicion, the police investigation was temporarily stalled because they did not know who was responsible for the tetrodotoxin that caused the death.
After thinking for a while, Inspector Megure turned to look at Mamoru Uchikawa, who seemed to be crying outside, with a look of suspicion in his eyes.
After confirming that the restaurant was no longer a suspect, Kōyū had already labeled Uchigawa Mamoru as the murderer in his mind, and this incident was definitely related to Uchigawa Mamoru.
Ai Ai, standing next to Kōyū, said, "His motive is that his girlfriend was having an affair, and he found out, so he did this, right?"
Guangyou nodded in agreement: "But there are no clues right now, which makes things a bit tricky."
Although the two already knew that there was a high probability that Mamoru Uchigawa was the murderer, they had not found any clues this time, and they could not conclude that Mamoru Uchigawa was the murderer based on the speculation of the two children.
Evidence is always important in everything.
No one can prove that Mamoru Uchigawa had direct contact with the deceased, and there is no evidence to say that Uchigawa injected tetrodotoxin into the deceased with a syringe. No needle marks were found on the body.
"What if Komori Aiko ate it willingly?" Kōyū pondered, stroking his chin.
Next, Kōyū walked to the table where Uchigawa and Mamoru were sitting. The table was untouched and remained exactly as it had been before the incident.
After glancing at the dishes on the table, Guangyou's gaze suddenly fell on a plate of food that hadn't been finished.
He lowered his head and approached the dish, taking a sniff; the fishy smell wafted directly into his nose.
"Fish liver?"
A smile appeared on Guangyou's lips: "I see."
Of course, all of this still lacks strong evidence, but evidence is the most troublesome thing.
Seeing the smile on Kouyu's face, Ai leaned closer to him and asked, "You understand?"
"knew."
Guangyou nodded. "They should use pufferfish liver. This restaurant is self-service, but only the head chef has the qualification to handle pufferfish, so it's impossible to do it in bulk. Therefore, they chose to give up on foods like pufferfish liver and only chose pufferfish meat, which has a lower risk."
Kōyū pointed to the plate of fish liver and explained, "Although there is no pufferfish liver, there is other fish liver here. Uchigawa Mamoru may have mixed poisonous pufferfish liver into this plate of fish liver. You should know what will happen next."
"So what do we do next? Should we continue looking for clues or...?" Ai asked, slightly puzzled.
Kōyū stretched lazily: "Let's just tell Inspector Megure all this. He shouldn't let us down. We can't afford to waste so much time in Ginza just on this case, can we?"
After saying that, Kōyū walked over to Inspector Megure and tugged at his sleeve.
When Inspector Megure turned his head and saw Kousuke, he frowned slightly but still bent down.
Guangyou then whispered his reasoning in his ear, along with the approximate location of the final evidence.
Inspector Megure's expression was initially serious, but then a hint of joy appeared. He had already suspected Mamoru Uchikawa, but as a police officer, he couldn't confirm the culprit based on his own assumptions. Besides, he only had a few clues, let alone evidence.
Watching Kōyū walk towards the store entrance, Inspector Megure adjusted his hat and nodded: "That Mōri guy isn't much, but his kids are all incredibly clever."
Ai and Kōyū left the store, and the crowd of onlookers outside had not yet dispersed, although there were far fewer than at the beginning.
As soon as he stepped outside, an older woman stopped Guangyou: "Little boy, did the person inside have a problem with what they ate?"
Guangyou stopped and nodded solemnly to the old woman: "Yes, that person died a terrible death."
"Oh my god!"
The woman panicked immediately, and there seemed to be some sauce from the restaurant's dishes still on her lips: "I'm in the prime of my life, I don't want to die!"
"No, no, I have to go to the store and argue with them. They have to compensate me." The woman looked at the store door, seemingly wanting to rush in.
Seeing the older woman's reaction, Kōyū chuckled secretly. Ài said irritably, "Is it really that funny to try and fool an older woman like this?"
"I'm not wrong, it really is because of what I ate that I had a problem," Guangyou said righteously.
However, he eventually explained the situation to the older woman. After the explanation, Kōyū and Ai left. Seeing the older woman's expression of relief, Kōyū's expression was equally complicated.
After leaving the restaurant, Kōyū and Ai started strolling around Ginza. Ginza truly lived up to its reputation as a shopping paradise, and Ai showed her true shopping prowess.
While shopping, Ai only bought one or two items, which were just small accessories and very cheap.
Although they didn't buy anything big, the two felt that the afternoon passed very quickly, perhaps because they were shopping together.
Kōyū's injuries had just healed, and it wasn't good for him to go shopping all the time. After shopping for a while, Kōyū and Ai went to a newly opened coffee shop. In their previous lives, this name would have been extremely popular.
The coffee shop is called Starbucks. It has only been open in Ginza for a short time, but it has already gained immense popularity.
The two stepped into the store.
Despite the crowds, it was still cool and refreshing. There was a long queue in front of the cash register. Inside the store, there were white-collar workers working on their laptops, some wealthy women chatting animatedly, and young women following their companions around, discussing which celebrity was handsome.
Ai frowned upon seeing this: "I remember when I was studying in the United States, this store wasn't this popular."
