The world of science is unscientific

When Ms. Sugimura arrived, everyone became hostile and started digging up each other's secrets, and in an instant, it seemed like everyone in the room was a suspect in a murder.

Hearing footsteps, Yusuke Suzuki quickly got out of bed and blocked the door with one hand.

huh?

Conan tried to push the door open, but it wouldn't budge.

Could it be!

Conan's face darkened. Could it be that the murderer was so deranged that they killed Suzuki Yusuke as well?

"Sister Ran! Something terrible has happened! I can't open Yusuke's room door, and... ugh~~~"

Yusuke Suzuki moved with lightning speed, opening the door, arresting, covering the mouth, and closing the door in one smooth motion.

If he doesn't step in soon, Ran Mouri will probably break down the door by force. How can this kid make such a connection?

Releasing his grip, Yusuke Suzuki yawned and stared coldly at Conan. "What are you going to do?"

"N-nothing," Conan said, sensing something was wrong, and immediately made his escape. He bumped into Ran Mouri who was coming towards him. "Ran-neechan, it's alright now. I'm leaving. Remember to apologize to Yusuke-nii for me."

"Yusuke-nii?"

Two minutes later, Ran Mouri peeked out and found Yusuke Suzuki leaning against the window smoking.

"It's nothing, Ran. I just got woken up by Conan while I was sleeping."

After leaving, Conan contacted Professor Agasa by phone and obtained the information he wanted.

After Masahiko Tsuruta's death, he still had two family members: his mother, Minako, and his younger brother, Katsuhiko. Conan then hitched a ride to Chiba Prefecture.

It was discovered that Masahiko Tsuruta's two family members had moved away long ago; his younger brother went to study in Germany and would occasionally come back, but had not been seen since a year ago.

The clues once again came to Conan on their own.

A sign on the doghouse in front of Masahiko Tsuruta's house reads 'JoHann'.

That evening, Conan returned to the villa and first went to sincerely apologize to Suzuki Yusuke to avoid being beaten up for no reason in the future.

During the time he was apologizing, Kogoro Mouri and the police officer concluded that Tatsuya Kumada had killed lawyer Tachibana before committing suicide.

Conan felt a chill run down his spine; this was way too fast.

He quickly lured Kogoro Mouri to the study, knocked him out with a tranquilizer dart, and after preparing, called everyone over and began his deduction.

After all the suspects and the two police officers arrived, Conan began his deduction.

Yusuke Suzuki was very curious about how Kogoro Mouri could sit in a chair with his head down while he was asleep.

Is there something holding it in place? Or do the muscles start to stiffen after the pose is done?

In short, it's amazing.

He turned to look at Ran Mouri again. She was usually very sensitive about Conan's sudden disappearance, but now she didn't move and listened attentively to the reasoning.

"Kumada Tatsuya was murdered, just like Attorney Tachibana! Moreover, the same person killed both of them, and that person is among you!"

As soon as these words came out, the whole audience was shocked.

After thinking for a moment, Suzuki Yusuke simply walked over to Kogoro Mouri's side. Although Conan had apologized, he still wanted to put more pressure on the famous detective.

Sure enough, as soon as he approached, Kogoro Mouri's voice trembled slightly, but fortunately he didn't go too far and stopped when he got close.

Seeing that Suzuki Yusuke was no longer moving, Conan breathed a sigh of relief and began to deduce. (This deduction is too long and involves many interactions, so I've simplified it; otherwise, it would have taken over a thousand words.)

Conan first explained the general process of the two cases, and identified three people as the most suspicious: Mrs. Kamei, Yuichi Sakuraba, and the deceased Kensuke Tachibana.

When Yuichi Sakuraba, who has no alibi, is suspected, Conan states that alibis are not important at all; the culprit goes to great lengths to obtain an alibi.

He then explained how he murdered Kensuke Tachibana.

Yesterday was the day with the greatest difference between low and high tide. The murderer had sailed close to Kensuke Tachibana, who was already asleep due to sleeping pills, beforehand, removed his life jacket, and then hooked the anchor onto Tachibana's boat.

When the tide comes in, the water level rises, and the anchor will naturally cause the boat to tilt, causing Kensuke Tachibana to drown, while the hook and anchor will sink to the bottom of the sea.

As for Tatsuya Kumada's suicide, it was even simpler; all he needed was fishing line, which he tied to the spindle of a washing machine set to a specific time.

After connecting the chair, it can be made to slip and fall without anyone's presence, so that Tatsuya Kumada, who has also taken sleeping pills, will naturally appear to have hanged himself.

The fact that the killer was able to get Tatsuya Kumada to take sleeping pills suggests that the killer knew Tatsuya Kumada.

Yusuke Suzuki listened quietly. He only knew the result, not the method. Listening to more of these cases would help him come up with ideas more quickly when he encountered similar cases in the future.

Conan continued his deduction, and everyone's suspicions pointed directly at Yuichi Sakuraba, because he had no alibi when the two cases occurred, and his behavior was suspicious.

The deduction ended there. Conan stopped talking, while Yusuke Suzuki returned to his seat behind him, lit a cigarette, and waited quietly.

Conan wanted to wait for Mrs. Kamei to confess on her own because he had not found any direct evidence.

Just as the police were about to forcibly take away Yuichi Sakuraba, Mrs. Kamei stood up and confessed.

The motive for the murder was almost identical to what Yusuke Suzuki had guessed. However, he did not expect that Attorney Tachibana would continue to defend Tatsuya Kumada and exonerate him for money, even after Kumada revealed his modus operandi and admitted to the crime.

He didn't feel the slightest bit upset that these two people were dead.

“I’ve been waiting for you to admit it yourself,” Conan said quietly, “because I believe you’re definitely not the kind of person who would keep quiet about a mistake you’ve made.”

“Actually, Mrs. Kamei had many opportunities to put sleeping pills in,” Yusuke Suzuki felt he should say something, “but she still chose to do it when Mr. Mori was staying at her place. She probably hoped that Mr. Mori would see through her method and arrest her, right?”

Mrs. Kamei, whose real name is Tsuruta Minako, bowed to Kogoro Mouri and said, "I'm sorry to have troubled you."

Chapter 104 Twilight Villa? I'm not going.

The case was resolved, and the next day, the auto repair shop staff arrived, the parts were delivered, and the car seemed to be fixed again without any repairs.

As a result, on the way back, not long after they started driving, Kogoro Mouri's car stopped again.

"Teacher, get on the bus."

"But..."

"I'll pay for the car for you."

"Is this...?"

"Are you going to go or not? If not, I'm leaving."

"..."

Under Yusuke Suzuki's firm stance, the group finally returned to Tokyo.

As for the car, Yusuke Suzuki bought it from a rental company, arranged for it to be towed back from the road, and sent directly to a high-end auto repair shop for disassembly to analyze what the problem was.

The result was that there was no problem.

It's fucking weird!

An angry Yusuke Suzuki sent the car to a scrap yard and crushed it into pieces.

A few days later, he received a call from Kogoro Mouri.

"Twilight Villa?"

"Yeah, do you want to come along? This time, all the detectives going are famous. You must really want to be one, hahaha."

"Don't go."

Yusuke Suzuki hung up the phone. There was nothing interesting about going there except to watch a 'high-level game' and get his car blown up.

Yesterday, Kaito Kuroba called to ask if he wanted to come along, and he generously betrayed his own teacher, saying, "Kaito, don't worry, you can disguise yourself as Kogoro Mouri, it's fine."

That night, while Yusuke Suzuki was fast asleep, Kogoro Mouri had already been stripped down to his underwear and tied up in the gas station.

Kaito Kuroba led Conan and Ran Mouri to the Twilight Villa, solved the secret, and then rode away in the morning sun.

Kogoro Mouri caught a cold after being exposed to the cold all night.

Before he had fully recovered, he took Suzuki Yusuke and his family onto Hattori Heiji's pirate ship.

"You brat, you should thank me properly," Kogoro Mouri said, still looking a bit listless, with a cigarette dangling from his mouth. "You showed up so abruptly, saying you had a case to take you to Fukui. Just because I came along doesn't mean I didn't have anything else to do."

“You don’t lose anything,” Osaka Black Chicken laughed. “Anyway, I’ll pay for the travel expenses.”

"Alright, which island are we going to now?"

“That place is called American Island,” Hattori Heiji said, looking into the distance. “Although it’s a small, isolated island, the people around here call it by another name: Mermaid Island.”

Yusuke Suzuki also came over and joined the group chat, saying, "I heard that there's an old lady on that island who lives by eating mermaid flesh in order to achieve immortality."

As he spoke, he took out some cold medicine and handed it to Kogoro Mouri, saying, "Teacher, take your medicine."

"Ah, thank you." Kogoro Mori obediently took his medicine.

At this point, Ran Mouri also mentioned that she had heard the rumor, and Kazuha Toyama added that she came along because she hoped to stay young and beautiful forever like that old lady.

It's as if they wouldn't have come without this reason. I'm afraid that if Heiji were to jump into the sea, Kazuha would follow him.

Yusuke Suzuki muttered a slight complaint, and couldn't help but think of Ai Haibara, who was still in Tokyo. Everyone else went out in pairs, while he could only barely manage to hang out with the bumbling detective. Life was too hard!

"Let me ask you something," Kogoro Mouri asked, his voice still slightly nasal after taking his medicine, "the person who asked you to come here, they don't want you to find some kind of mermaid, do they?"

Hattori Heiji feigned mystery, saying, "On the contrary, the letter of authorization only contained a few simple sentences, and it was clearly written in a hurry."

"It says, 'The mermaid is about to be killed, please save her.'"

Conan listened from the side and kept yawning, as did Yusuke Suzuki. The former didn't believe that mermaids, creatures from fairy tales, actually existed, while the latter remembered this part of the story.

Not long ago at the Twilight Annex, Hattori Heiji didn't go because he had to take an exam. Although the letter requesting this time was addressed to him, it was addressed to 'Kudo Shinichi' at the beginning. That's why he couldn't wait to bring this request to Conan and ask him to come along.

Yusuke Suzuki came over because he simply couldn't refuse.

He had already declined the offer to stay at the Twilight Villa, so it wouldn't be good to decline again this time. Besides, he hadn't seen Hattori Heiji for a long time, and it would be too inhumane for him to refuse.

While he was lost in thought, Heiji Hattori and Conan kept whispering to each other and kept gesturing to Yusuke Suzuki to come and join the group chat.

Upon arriving on the island, the staff in charge of reception told them some news that they had not expected.

Ms. Kadokawa Saori, who wrote the letter to Hattori Heiji, disappeared three days ago and her whereabouts are unknown.

"Counting back three days from now, that's exactly when that letter arrived at my house," Hattori Heiji muttered to himself, trying to deduce some clues.

Then, the staff told everyone that today was the day of the island's annual dugong festival, and explained the location where Motokyo Saori had previously worked.

The streets are filled with mermaid-related products, from mermaid amulets to dugong pies; the whole island seems to be associated with mermaids.

"What is the Dugong's Arrow?" Kogoro Mouri was still chatting with the proprietress of the shop where Saori Kadokawa worked.
