"So, they think one of us is Shinichi Kudo, but there's no way to know for sure?" Conan then whispered.

"I guess so." Kaedehara agreed.

The fact that one person has become two people is unbelievable, not to mention that the one who seems to have also become smaller has not become two people, which further makes it difficult for the other person to associate such a thing.

"But," he went on to remind Conan, "even then it is dangerous. ”

"I know. But I don't know how, the guy seemed to be sure of my identity when he first saw me. Even if I saw it ten years ago, it wouldn't be like this..."

Fortunately, Kaede Yuan helped cover it, so the other party couldn't be sure...

"Maybe she's getting smaller, too." Kaede meant something.

Because he and Gray Yuan shouldn't be in London, and there is no reason for him to see a shrunken version of Marie Akai, he has no plans to use this to debunk the secret of Sera's innocence for the time being.

And it's almost his own over there, so Kaedehara hasn't told anyone about it yet.

Conan subconsciously thought that Kaedehara was talking about the innocence of Seliang.

"How is that possible?" Conan immediately vetoed, "She's a high school student now, not to mention the fact that she saw it ten years ago...

If it really gets smaller, it can only be that a single part has become smaller...

However, this idea is a bit too rude, so even in the face of another self, Conan still didn't say it.

In this way, the two of them whispered and speculated on the purpose of the next Shiro Zhenjun calling them over, and soon, Kaedehara and Conan followed Xiaolan and Sonoko to the public swimming pool.

It was very convenient for elementary school boys to swim, and Kaedehara and Conan changed into the swimming trunks they brought and walked out to wait for Xiaolan and Yuanzi.

After a while, Xiaolan and Yuanzi, who were both dressed in bikinis, walked out of the locker room to meet them.

Conan couldn't help but look at it a few more times.

"It's huge!" Xiaolan looked at the pool and sighed.

"Well," Sonoko nodded, "but it's a little narrower than the pool in my villa." ”

"Just a little?" Kaedehara said curiously.

"Just a polite remark, of course, little ghost." The garden bent down to look at Kaedehara, "But it's also good to have this level here!" ”

"I don't know what kind of swimsuit I'll wear, I'm really looking forward to it!"

"I guess it's a sporty one-piece swimsuit!" The garden straightened up and speculated.

"Conan, you're looking forward to it, aren't you?" Xiaolan bent down to look at Conan.

She was a little closer to Conan, so that somewhere she was closer, just at Conan's eye level. This made Conan's eyes straighten a little, and he blushed a little.

"Ahh Conan replied with two sentences.

It's so satisfying...

Conan thought to himself.

However, as soon as this thought came to his mind, another thought suppressed it.

Conan instinctively looked at Kaedehara again, and found that Kaedehara was not looking at Xiaolan but looked back at the entrance, and felt a little more comfortable.

"But, isn't Sister Shiliang flat-chested?" Yuanzi said.

"Sister Shiliang?" Xiaolan was a little puzzled.

"yes, don't you think it's very nice to call her Sister Shiliang?"

"That's what I said..."

"It's okay!" Shinsumi Sera walked over, and she was also wearing a striped bikini.

Just now, Kaedehara glanced back because he noticed the movement of her coming.

Xiaolan and Yuanzi were a little surprised when they looked at the swimsuit on her body.

"Just call me Sister Shiliang!" Sera Shinsumi continued, "When I was a child, people did call me that! ”

"You," Yuan Zi couldn't help but complain, "although your breasts are not big, your mind is not small!" ”

"Mind?"

"Huh? Miss Garden? They were chatting when someone next to them recognized the garden.

Everyone looked over, and it was a man in his early thirties with glasses.

His name is Yorito Samaki, and he is the secretary of President Oiso, and President Oiso's Oiso Foundation is a subsidiary of the Suzuki Foundation, so he recognized Sonoko.

As soon as Mr. Zuomaki and Sonoko chatted a few words, they were called out by Miss Nagami Oiso, who was lying on a beach chair next to her, to help rub the sunscreen.

Along with Nagami Oiso, her half-sister Hamaka Oiso, and the manager of this hotel, Mr. Toshima.

Those people said a few words, and from the conversation, Kaedehara heard that Mr. Zuomaki, who is the fiancé of Oiso Nagami, seems to have a leg with Oiso Hamaka, and Oiso Nagami's personality seems to be very bad...

Next, just as Xiaolan and the others were about to enter the pool, Feng Yuan knew what was worse.

Oiso Nagami's necklace seems to have been lost, and because she thinks it may have been dropped in the pool, she immediately asks the manager of Toshima to drive all the guests out of the pool and search them, and also seal off the place.

Kaedehara and the others, who hadn't had time to enter the water, escaped the trouble of breaking up with her about the body search.

They had to go back to the locker room to change their clothes, and then stopped by the pool to take a sneak peek.

There was no one else in the pool, and Eisomi Oiso even took a diving oxygen tank and wanted to dive down to find the necklace. Then she also kicked out Manager Toshima and the others, planning to find it by herself.

When they returned, they happened to see her throwing a tantrum away and driving people away.

“… Really, is the eldest lady so willful? Shiliang Zhenchun couldn't help but complain.

"Garden, you're not like that, are you?" Xiaolan looked at the garden.

"Hmm... Probably not..."

Yes, we won't be kicked out together...

Kaedehara thought to himself.

The swimming thing was in the soup, but it was all here, and the time was almost noon, so they simply went straight to lunch. After lunch, they were ready to leave.

"You all want to come to the pool to play," Sera said to Xiaolan and Yuanzi embarrassedly, "but this happened." ”

"It's not Seliang's fault!"

"Sister Shiliang, sister!" Yuanzi reminded Xiaolan, "But the hotel's lunch is delicious, so forget it!" ”

"yes!"

"Huh?" Sera Masumi looked back at Kaedehara and Conan, who had stopped in place, "What's wrong?" ”

"Ah, nothing," Conan turned around, "and the waiters at the hotel seem to have been in a bit of a commotion since just now..."

Behind them, at the end of the aisle, there were two waiters talking about something. Kaedehara heard it, but didn't say it directly.

Because whether you say it or not, everyone else will know.

"What? Miss Nagami is missing? ”

Shira Zhenjun looked at the manager of Toshima and the other three people who had just met before in surprise, "Didn't she look for her necklace in the pool?" ”

"Yes, it should be like this!"

"But all of a sudden, she was gone." Oiso Hamaka explained, "We also looked for the changing rooms and restrooms near the pool. ”

"It doesn't seem like I'm going home either!" Left volume secretary to make additions.

"Hey, that!" While he was talking, the shocked voices of two waiters on the edge of the pool behind him, "It seems to be a person!" ”

"Huh?" The crowd looked back.

"You—Look!" One of the waiters continued, his hand pointing to the pool, "The one that sank in the pool!" ”

They all ran over.

Then they were all stunned for a moment.

In the middle of the pool, a woman was lying at the bottom of the pool, most likely out of her life.

That's Nagami Oiso.

The secretary who ran over took off his glasses, and the manager of Toshima also took off his shirt while running, and the two jumped into the pool one after the other.

There were also two waiters next to him, and they were not needed for the time being, so they didn't go into the water.

"Call an ambulance and the police!" Shira Zhenjun shouted to the stunned waiter on the side.

"Yes, yes!" The waiter hurriedly took out his mobile phone.

"Miss? Yongmei? Secretary Zuomaki quickly picked up Nagami Oiso, who was sinking at the bottom of the pool, and in the process, the oxygen cylinder she was carrying also fell off, and she was held in the arms of Manager Toshima.

"But that's strange," said the waiter, as he dialed the phone, "and there was nothing in the pool ten minutes ago!" ”

Xiaolan and Sonoko didn't immediately understand the meaning of this sentence, and still stared at Osa Nagami, who had just been picked up.

However, both Sera and Conan realized from these words that this was likely a murder case, so they both looked at the waiter.

And then—

"Mr. Toshima," another childish voice came from beside them, "what are you doing?" ”

This is Kaedehara's voice.

Sera and Conan hurriedly turned around again, followed the meaning of Kaedehara's words and looked towards the field, and after sweeping around, they saw Manager Toshima in the pool.

Manager Toshima, holding an oxygen cylinder, froze in place.

……

A moment later.

"Drowning?" It was still the Twilight Police Department who came to the scene.

"Yes," replied Officer Takagi, "and the time of death is presumed to be between twelve and one o'clock in the afternoon." ”

"Hmmm! But I really don't understand! The water in this pool is not deep enough to stand up! Why do you drown? ”

"It's easy." Shiliang Zhenchun said.

"Huh?" The Twilight Police Department looked back and found that Kaedehara, Conan, and the others were all standing aside, "So you're all here..."

No wonder there are cases ...

I hope this one named Sera won't be infected by Maori like Conan...

"What did you just say?" the Dusk Police Department asked.

"Miss Oiso Nagami—"

"Nagami Oiso? Who's that? ”

"Uh... It's the deceased, and she's the eldest lady of the Oiso Foundation. Officer Takagi hastened to remind the Twilight Police Department.

"Oh, I see."

Shira Zhenchun, who was interrupted by this reasoning, was a little speechless, but he still said it again:

"Miss Oiso Nagami dives here alone with an oxygen tank on her back to find her lost necklace. Just grab her by the back of the neck in the pool and pull the oxygen cylinder's respirator out of her mouth so that she can't breathe in oxygen. ”

"Miss Nagami, who is carrying an oxygen tank and wearing a diving suit, easily sinks to the bottom, and her cry cannot be heard in the water." As he spoke, Sera looked at Toshima Manager who was standing aside and was guarded by two waiters, "That's right, Mr. Toshima Enze, the hotel manager?" ”

"What!?" The Twilight Police Department and Officer Takagi looked over in surprise. They have only just begun, and the case has already been solved?

Manager Toshima was silent.

"Wait, wait," the Twilight Police Department said quickly, "Let's go through the details first..."

He didn't know what was going on, but Brother Seliang suddenly began to reason, making him completely confused.

"Ah, yes..."

Then, with the cooperation of others, Shira Zhenchun explained the situation in detail at that time. However, just when the Twilight Police Department thought that it could be closed like this, the secretary of the left roll raised questions.

"But, ten minutes before I found Yongmi sunk at the bottom of the pool, there was nothing in the pool, right?" As he spoke, the secretary looked at the waiter beside him, "That's right, right?" ”

"Yes, that's been said before. The manager and the three of them came here to look for Miss Nagami, but we didn't find it. As a result, when I came back to look for it ten minutes later, I found that the eldest lady had sunk at the bottom of the pool. ”

"It's past two o'clock in the afternoon." The waiter looked at Kaedehara and them, "They were also nearby at that time, and they confirmed with me before..."

"That's right," Officer Takagi nodded, "That means that the body of Miss Nagami, who died at noon, was hidden somewhere... And then it was about two o'clock in the afternoon and then moved to the middle of the pool, right? ”

"That's not right." Kaedehara said.

"Huh?"

"Thanks to Kaedehara noticing Mr. Toshima's small movements, we quickly thought of it." Shiliang Zhenchun said, and reached out to try to touch Kaedehara's head, but was dodged.

But she didn't care.

"Small, small movements?" The Twilight Police Department looked at Manager Toshima.

Manager Toshima remained silent.

"That's right, he took the oxygen cylinder he picked up from the pool and tried to smash the sink." Shira explained, "Although he still smashed the sink when he noticed it, it also exposed him..."

"Water, sink?"

"yes, it's a magic trick done with a sink - Miss Nagami's body is actually in the pool all along."

"W-What?"

"Because of the total reflection of light." Sera went on to explain, "Although water and air are transparent, the refractive index of light is different. When light enters air with a lower refractive index from water with a higher refractive index, if you look at it at a near-horizontal angle at the interface between water and air, the light will be reflected back as if it were all reflected back by the mirror, and you will not be able to see what is behind the mirror. ”

Except for Shinsumi Sera, Kaedehara and Conan, and Manager Toshima, who was silent, everyone else looked confused and didn't understand at all.

"Let's demonstrate it! Kaedehara! Conan! ”

"Hmm!" Kaedehara and Conan replied in unison.

The Twilight Police Department and the others looked over there and found Kaedehara and Conan standing by a sink.

This is another sink they borrowed from the hotel before.

Under the watchful eyes of the crowd, Kaedehara tossed a ten-yen coin into a sink filled with water.

"Look," Conan explained, "can you see the ten-dollar coin that Kaedehara threw into the sink, right?" ”

"Hmm."

"yes."

"But if you turn the cup upside down, keep the air inside, and put it on a ten-dollar coin..."

It was still Kaedehara who was in charge of the operation, and Conan was in charge of the explanation, and at the same time that the cup was buckled, the ten-yen coin disappeared from everyone's sight.

"Gone, gone!"

"That's amazing, Conan, Sora!" Xiaolan exclaimed.

"It's just a simple science experiment!"

"Sister Xiaolan, you should have studied it when you were in school!"

"Yes, is that so..."

"It's the same with Miss Nagami." Sera Shinjun then reasoned, "As long as there is a sink in the pool that is upside down and filled with air, no one else will be able to see her." ”

"But if you look directly from above, can't you see it?" The Twilight Police Department looked down at the cup used for the experiment.

"If you look at the boundary between air and water from a small angle of injection, you won't have a mirror effect. But this is the pool, and there's no way to see it from above, right? ”

"Yes, it makes sense!"

In other words, after the criminal drowned Miss Nagami, who was looking for a necklace, he hid her body under the pre-prepared sink in the pool, and then used a fishing line to pass through the drains at both ends of the pool to secure the tank.

After that, just tilt the sink a little bit and reach through the gap to open Miss Nagami's oxygen cylinder and fill the tank with air. The fishing line is bouncy, so if you just tilt the tank a little, you should be able to do it. ”

"But," the Twilight Police Department asked, "can you hold the sink in place with a single fishing line?" The sink is full of air. ”

"If you make four grooves at the bottom of the sink and run it back and forth with a fishing line, it won't be so easy to float." Seliang Zhenjun winked at Kaedehara, "Thanks to Kaedehara's blessing, Mr. Toshima was discovered before he could completely destroy the sink..."

"Go get the pieces up!" The Twilight Police Department hurriedly ordered Officer Takagi.

"Mr. Toshima took advantage of the fact that Mr. Zomaki pulled Miss Nagami's body up from the pool, put his foot into the sink, dragged the sink under the water, and when he moved the sink to the corner, he wanted to smash it on the spot with an oxygen cylinder..."

"You probably think everyone else will be drawn to the corpse fished out of the water, and they won't hear the sound in the water or be seen in action, right?" Shinsumi Sera asked Manager Toshima.

“… Oh, yes. The method was completely exposed, and the manager of Toshima was no longer silent, "but it still didn't escape the eyes of this little brother." ”

Or maybe the ears... Conan complained in his heart.

Manager Toshima's motivation is related to his sister.

His sister's family wanted to live in the hotel's penthouse suite to celebrate their son's birthday, but the suite they booked was temporarily snatched away by Nagami Oiso.

As a result, when his sister's family had to rush to another hotel, they were accidentally hit and killed by a friend's car in which Nagami Oiso was riding. Oiso Nagami then asked Manager Toshima to help him commit perjury, and Manager Toshima made a murderous move.

It's just that he wanted to quietly smash the sink in front of everyone to cover up his methods, but it was also exposed.

And so the case ended.

"I'm so sorry that you came here on purpose, and I haven't been able to entertain you properly." Shira sent Kaedehara and them out of the hotel.

"There's no way around it, there's a case going on."

"Speaking of you," said the garden, "I used to be at 'a certain dessert show,' and I always appeared and disappeared in unexpected places, just like a magician." ”

"Magician?" Shira was stunned for a moment, and looked at Kaedehara and Conan, "Magician... It's not me! ”

She said it on purpose to observe the expressions of the two people, but she was surprised to find that the expressions of the two people were the same, as if she didn't know what she was talking about.

Damn it...

It's really good to pretend...

However, although Kudo Shinichi didn't show anything, hearing this, Xiaolan had a faint impression of what happened ten years ago.

"That's... Sister Shiliang, did you and me before..."

"Ah, you called her a girl just now!" Yuanzi said.

"Ah, I'm sorry!"

"It's okay, it's okay!" Seliang Zhenjun waved his hand and ran towards the hotel, "See you next time!" ”

Xiaolan said goodbye to her, and then out of the corner of her eye, she saw in the hotel lobby, Shiliang Zhenchun and a little girl wearing a hat and looking like a junior high school student chatting about something.

Conan hadn't noticed this, but then he noticed Kaedehara put his phone away. Realizing something, Conan subconsciously looked into the hotel, only to find that Sera was innocently blended into the crowd.

Xiaolan and Yuanzi are also urging him and Kaedehara to keep up.

"You guy," Conan whispered to Kaedehara as he followed Ran, "don't remind me." ”

"Who makes you lose concentration at such a time." Kaedehara replied, "And the man has been quietly observing us for a while..."

Toshima manager is not alone in feeling that his small actions will not be detected.

"Huh? The one in the hotel room? ”

"yes."

"Damn..."Conan was even more depressed, and then reacted, "You just secretly took a picture, right?" Show me! ”

"I didn't take a picture."

"Huh? I saw it. ”

"It's a video." Kaedehara took out his phone and sent the video to Conan, "I sent it to you." ”
