Ah first examined the raft carefully, and found that there was a tiny hole in the top of the raft, as if it had been punctured by a needle or a toothpick.

Ah Yi frowned, as if he had discovered something, but his feelings were very vague.

Zero also noticed the hole and said, "This must have been done by one of the victim's companions, right?" ”

"Does this little hole have anything to do with the victim's death?" Ah Yi touched his chin and said, "In this case, the murderer should be among the three companions." ”

"It's too early to tell, but it's worth asking the three companions." Zero said.

Ah nodded: "Let the police gather the three of them, and then ask them separately one after another." ”

Zero told Shiratori about his request, and although Shiratori thought that their efforts would be in vain after all, he still sent someone to summon the victim's companion as Zero said.

During this time, Zero asks Shiratori about the identity of the victim.

According to Shiratori, the victim's surname is Chijira, whose name is Mio, and she is the daughter of the director of Chijira Hospital, a well-known hospital in China, and is currently studying at a key medical university in China, which can be described as having a bright future. And the three companions are all Mio's classmates, one of the men with glasses is named Tsujimura Makio, the other is a cheerful boy named Takuji Shitsumoto, and the remaining woman is named Chika Ogino.

Of course, the police have already done a brief questioning of them and know the general situation. Mio Chiyoshi had been sleeping in a recliner until she went to the staff break room to find a bed to sleep in because of her low blood pressure. Later, the three of them never saw Mio again, until they heard the news that someone had been killed in the swimming pool, and when they came to take a look, they realized that the victim was actually Mio Chiyoshi.

After that, the three were summoned together and taken into the break room for questioning.

The first to enter the lounge was Tsujimura Makio, who was also a little surprised to see that in addition to a police officer, there were two people who looked like high school students, a man and a woman. When he recognizes the boy as the one he had clashed with Mio earlier, he can't help but wonder even more.

Aichi thought for a moment and asked, "Mr. Tsujimura, may I ask if you haven't seen Miss Chijira since she went to the staff lounge?" ”

Tsujimura was a little embarrassed and didn't know whether to answer the boy's question. He looked at Shiratori, and when he saw Shiratori nodding his head to answer truthfully, he said, "That's right, I haven't seen her since Mio left...... However, this statement may not be entirely accurate, because I had caught a glimpse of her rubber raft, but it was not clear from a distance at that time, and I thought that she should not have rested so quickly, so I thought that the person on the rubber raft might not be Mio, so I didn't pay much attention, and only remembered that there were two Cokes on the rubber raft. Later, after the incident, I realized that what I saw was indeed Mio herself. ”

"What were you doing during the time that Miss Chijira was resting?"

"I was sorting out parasols by myself...... By the way, you don't suspect that I killed Mio, right? Please, not to mention that I wasn't there for Mio when he was killed, and I had no reason to do that. I've been trying my best to please her in the past few years, just so that I can go to Chijira Hospital after graduation, how can I kill her and destroy my future? ”

Hearing this, Ah Yi thought silently, and at this time, Zero asked, "Then do you have any disputes between Mr. Shichimoto and Miss Ogino and Miss Chijira?" ”

"Chika's words have always been respectful to Mio, but Mio's attitude towards Chika is very bad...... Although her attitude towards us is not much better, she is especially excessive towards Qianhua, and it is not impossible for Qianhua to have a grudge. Zhuoji's words, he recently talked about a girlfriend, which made Mio very unhappy, and even threatened not to let Zhuozhi enter Senjira Hospital, so it is normal for Zhuozhi to have a grudge. ”

"Mr. Shichimoto talked about a girlfriend that upset Miss Chijira? Could it be that Miss Chiyoshira likes Mr. Yoshimoto? ”

"How is it possible, she treats the three of us like a servant. If you insist on saying it, it's like a servant under the master's hand who has fallen in love without permission, so it makes the master unhappy...... Something like this. ”

After the questioning of Makio Tsujimura, the next person to enter the lounge was Takuji Shichimoto.

Ah Yi still had the same old question: "Mr. Sizhimoto, may I ask if you have seen Miss Chijira after she went to the staff lounge?" ”

"Nope."

"And have you ever noticed her rubber raft?"

"No, I was a little hungry at the time, so I went to buy something to eat and didn't see anything in the pool until the commotion."

"Who do you think the killer might be?"

"Isn't that the high school girl? If it weren't for her, the most motive for killing would have been Makio. Makio's father has been a doctor at Chijira Hospital for more than ten years, and he has always been the director's subordinate, but not long ago he seemed to have had some conflict with the director and was fired. It is not surprising that Mu Xiong is resentful and wants to seek revenge on the dean's daughter. ”

The last person to be questioned was Chika Ogino, and in the face of Aichi's first question, her answer was "I haven't seen it". Later, Aichi asked, "What were you doing when Miss Chijira was resting?", and her answer was, "I swam alone."

Finally, in the face of Ah Yi's question "Who do you think the murderer may be", she thought for a while and said: "Although Mio has always been too much to us, we have endured it for so long, how can we kill people now that we are about to graduate, anyway, I don't think Tsujimura-kun and Shizhimoto-kun will kill Mio...... The murderer should still be the high school girl, after all, the current middle school is lively and angry, and it is possible to kill someone on impulse. ”

After the questioning of the three of them, Ah Yi frowned and rubbed his eyebrows with his right hand.

Although it cannot be said that these inquiries have not been completely informed, it is true that there is too little useful information.

Shiratori began to summarize: "Chijiryo Mio entered the staff lounge alone at around 11:30 due to physical discomfort, and the incident happened at nearly 12 o'clock, and none of the three companions had contact with Miss Chijira during this time, so sure enough, it was impossible for them to commit a crime. ”

However, Zero said: "At least for now, there are two obvious suspicions. ”

Shiratori was stunned: "What suspicion?" ”

This time it was Ah Yi who answered: "The first suspicion is that Miss Chijira's rubber raft has been pierced with a needle and a small hole. ”

"I already know this, but I don't think it has anything to do with this case."

"The second suspicion is Coke."

"Coke?" Shiratori was still puzzled.

"Mr. Tsujimura said just now that there are two Cokes on the raft."

"That's right, Coke cups were also found in the pool, the kind of paper cups that were covered with plastic lids. But what's so strange about it, Coke is available in the commissary. ”

"A glass of Coke sold at the commissary is 500 milliliters, and two cups add up to one liter. A girl who just went to the lounge to lie down because she was not feeling well not long ago is ready to drink up a liter of Coke by herself? ”

"That's a bit weird...... But it's not unreasonable, for example, I have a colleague who likes to smoke and still smokes when he coughs. If Miss Chijira likes to drink Coke, this is understandable. ”

Ah Yi scratched his head, and the hairstyle that was already a chicken nest was scratched even more messy by him.

But at that moment, Shiratori suddenly spoke, "But if it comes to strange things, I think of one. ”

"What's the matter?" Zero and Ah Yi asked in unison.

"When we were sorting through the deceased's belongings, we didn't find her underwear...... Her coat and skirt are there, but she just can't find her underwear, which is quite strange. ”

After the white bird finished speaking, Zero and Ah Yi had a flash of inspiration at the same time.

I saw a pair of eyes showing a determined gaze: "I know what's going on, the puzzle has been solved." ”

Zero also smiled at Shiratori, "Thank you this time, Officer Shiratori." ”

Although Shiratori still didn't know what was going on, Zero's smile still made him feel a little intoxicated.

No, Shiratori Renzaburo, what you're after is Officer Sato, how can you be tempted by other girls casually, not to mention that the other party is still a high school student.

Zero continued, "Officer Shiratori, call all three of them. Ah and I have repeatedly investigated some things, and we will be back soon. ”

Shiratori came back to his senses, let out an "oh", and ordered his men to call someone.

Soon, Makio Tsujimura, Takuji Shitomoto, and Chika Ogino were summoned again. And after Zero and Ah Yi investigated some things, they also returned to the lounge.

For being repeatedly summoned by the police, Tsujimura and the other three were also very dissatisfied, but they had to suppress their grievances in front of the police at this time.

I only heard Ah Yi say: "The truth has been revealed, and the murderer of Miss Chijira is among you!" ”

Hearing Ah Yi's words, Tsujimura Makio, who was already dissatisfied, said directly: "I said this high school brother, didn't you all ask the three of us just now?" We weren't with Mio when she was killed, so how could it be a murderer? Aren't you going to start talking nonsense to help your companion get away with it? ”

"The murderer's purpose was to make people think that he couldn't kill Miss Chijira at that time."

"W-What does this mean?"

"Don't you think it's strange? Someone like Miss Chijira, who likes to dictate to you, got on a rubber raft alone without notifying you? ”

Hearing Ah Yi say this, the three of them gradually frowned, and the fourth to Ben Zhuozhi said: "That's right, if she wants to get on the rubber raft, she will definitely notify us in advance, maybe there will be a lot of things for us to do, and it is really unreasonable to sneak on the rubber raft alone." ”

Ah Yi continued: "Here's the thing. The murderer had added a small amount of sleeping pills to Miss Chijira's drink beforehand, which would not make her fall asleep immediately, but would make her feel dizzy and uncomfortable. So Miss Chijira, who thought she was suffering from low blood pressure, went to sleep in the staff lounge, and finally when she lay down in bed, the effect of the drug completely failed, and she fell asleep quickly. Miss Chijira was in a bad mood when she had a hypotensive attack and didn't like to be around people, and if there were people in the lounge, she would definitely pay them to leave. The murderer knew her character and could anticipate such a situation, so he estimated the time and sneaked into the lounge after Miss Chijira had completely fallen asleep. After entering the lounge, the murderer took out the syringe and the empty paper cup prepared in advance, and used the syringe to draw one liter of blood from Miss Chijira's body and inject it into the two paper cups. ”

"A liter of blood?" The three of them all changed color a little when they heard this, and they naturally knew very well what the concept of losing one liter of blood was.

Ah Yi wanted to continue talking, but Zero gently kicked his calf. You've said so much, why don't you let me speak, otherwise wouldn't I have no chance to perform?

Ah Yi looked at Zero in some surprise, what did she kick herself, could there be something wrong in her reasoning?

However, just when Ah Yi turned his head, Zero had already answered: "After the murderer finished drawing blood, he should have dragged Miss Chijira to the shower room in the lounge, cut through the place where she had been drawn just now with a razor, and covered up the traces of pinholes with cuts while killing Miss Chijira." The killer then opened the shower head and washed the blood away with water until the body stopped bleeding. Then the murderer placed the body on top of the rubber raft that had been prepared long ago, and placed two paper cups filled with blood on the rubber raft, and covered the lids of the cups, I guess there were some drugs in the cups to prevent blood clotting. Next, the murderer used a needle to make a small hole in the rubber raft and pressed the razor of the murder weapon under Miss Chijira's body, so that the preparation was completed. ”

Shiratori asked, "But won't anyone find out about her putting Miss Chijira on the raft?" ”

Ah Yi was about to answer, Zero kicked him again, and then took advantage of his surprise to say: "Ah Yi and I have just investigated, the pool will be tested in different areas at different times, and swimming is prohibited in this area during the test. The murderer should have found out the information in advance to know the time of water quality testing in each area, so he pushed the rubber raft into the water when the testing in a certain area was completed and the tourists had not gathered, so as to greatly reduce the risk of being discovered. In fact, it doesn't matter if it is discovered, because as long as the previous methods have not been cracked, the murderer has a lot of excuses for himself.

According to the murderer's idea, the rubber raft will gradually leak because of a small hole, but because the hole is small, the air leakage rate is also very slow, and it will take a while to capsize because it cannot bear the weight of the corpse. At that point, the corpse, the murder weapon and the paper cup filled with blood fall into the water, and the blood spreads around the corpse, and the murder weapon floats aside, creating the illusion that the deceased was killed in the pool, and tourists who happen to be near the deceased will become suspects. Unfortunately, however, the raft crashed into Miyuki before it sank with an air leak, which led to the scene of Miyuki killing people. ”

"I see, it's really a chain of tricks." Shiratori sighed at first, and then asked, "Then who is the murderer?" ”

Ah Yi still wanted to answer, but after glancing at Zero, he gave up. was kicked twice in a row, how could he not see that his cousin was stealing the show?

However, Zero didn't speak, but signaled with his eyes that it was Ah Yi's turn to speak. Seeing that Ah Yi didn't have a stubble, he was still a little anxious. Please, I'm your sister, so naturally I can't always deprive you of the opportunity to perform, and it's a bit of a tacit understanding, okay? Like when Heiji and Conan (Kogoro) revealed the truth together, you and I said it one by one, neither robbing words but also having a clear division of labor, what a tacit understanding, why did my cousin and brother have no tacit understanding?

After two seconds, Ah Yi finally reacted and said, "In fact, if you want to reveal the identity of the murderer, there is still a problem that needs to be solved first...... Among the items found by the police of the deceased, there was one indispensable thing missing, and that was underwear. Miss Chijira always wears underwear when she changes her clothes after swimming, but she is the only one who doesn't have underwear in her belongings? ”

Chika Ogino said, "How, how can this be...... Could it be that it was taken away by the murderer? ”

"No, I don't think Miss Chijira came with underwear at all, when she came over, she was wearing a swimsuit directly under her coat, and I guess she was going to do the same when she went back."

Chika continued, "It can't be like this, right...... It's okay to say when I come over, but once I swim, the swimsuit gets wet, so how can I just wear it back......"

"I think so, Miss Chijira has no intention of going into the water at all, although she comes to the water park, she plans to spend the whole time on the shore. Therefore, when you come in a swimsuit and go back in a swimsuit, you naturally don't need to prepare underwear. ”
