"I originally thought it was strange how the fortune teller could know all the preferences and habits of each fortune teller, as if she had followed and monitored the people who came to tell fortunes. But every day, she She accepts reservations from many people. If she has to track everyone, it will obviously be impossible.
"So yesterday, I tried to find a few people who had gone to the aunt to have her fortune told, and learned some information from them. Then, I discovered some commonalities between them - —
"That is, their daily consumption is basically on this commercial street. So, I immediately noticed that this street is obviously different from other streets!"
While watching Gao Yuan remove the camera used for the vehicle's reversing image, Shirozuka Jade, who had roughly guessed the reason, looked slightly satisfied, and briefly explained her investigation process with a faint smile.
In response to this, Xiao Ai on the side looked a little cold, holding his hands in front of him, looking at Gao Yuan who was investigating within the cordon, without turning around to look at Chengzhong Jade beside him, and asked Chengzhong Jade:
"Oh? What's the difference?"
"It's the surveillance camera on this commercial street!"
Looking up and pointing at the surveillance cameras installed at regular intervals on this street, Shirozuka Hisui replied.
And as this answer appeared, both Xiao Ai and Koizumi Hongzi couldn't help but be stunned, and then they immediately figured out the trick——
"In other words, the reason why the fortune teller can tell fortunes so accurately is because she knows in advance the situation of everyone who comes to make an appointment for fortune telling through the monitor in the commercial street?"
Regarding this conclusion, Xiao Ai finally no longer continued to make a cold expression towards Chengzhong Jade, but was slightly surprised. She couldn't help turning her head to look at Chengzhong Jade, as if she was completely relieved, because she heard the fortune teller yesterday The results of the fortune-telling for myself made me feel worried, and I felt relieved. I confirmed to Shirozuka Hisui with a slight calmness——
"Well, that's right. Because in order to prevent crime, this commercial street has installed many surveillance cameras a long time ago. Whether it is the various shops on the commercial street or the nearby Mihua Municipal Building, as long as you are in this area Within the range, you can see it no matter where you go.”
Regarding the change in Xiao Ai's attitude, Chengzhong Jade on the side also told her the results of her investigation:
"And because this commercial street and the Mihua Municipal Building next to it are enough to meet the daily consumption of everyone nearby, so as long as people living here, their hobbies and habits can be more or less observed by observing them It is judged based on the consumption situation here, so as long as you can see the monitoring content here and find the activity track of the person who made an appointment to come for fortune telling, you can know the habits and hobbies of the fortune teller.
"And as long as you know this, the fortune teller can use this to make people think that her fortune telling is really accurate, so naturally, they will think that the fortune telling results she gives later will also be very accurate. After all, For people who don't know themselves but can tell their own preferences and habits at once, it is reasonable for people to think that all the fortune-telling results of the other person are divinely accurate.
"But in fact, there is no essential difference between that fortune teller and other fortune tellers. He just uses the 'Barnum Effect' to draw some general conclusions."
After saying this, Chengzhong Jade continued to look at Gao Yuan. After Gao Yuan used a tool to open the reversing image camera, he carefully observed the structure inside, and immediately called the forensics department personnel, and After saying a few words to the forensics department personnel, the forensics department personnel immediately changed their expressions and took the dismantled camera for inspection——
"Brother Mingzhi, what did you find?"
At this time, seeing this situation, Officer Mumu immediately realized what Gao Yuan had discovered, so he hurried up and asked.
So, Gao Yuan nodded and replied:
"It was discovered that the car's reversing image camera had been tampered with and a receiving antenna was installed inside."
"What...what do you mean?"
Listening to Gao Yuan's words, Officer Mumu asked with some vague understanding.
"The principle of the reversing image is to transmit the image captured by the camera installed at the rear of the car to the display screen in front of the driver's seat through the built-in line. When the driver pushes the gear to the reverse gear, the image automatically starts to be transmitted. But in essence , this is a data transmission process, so if you want the final picture that the driver sees to be different from the picture taken by the camera, it is technically possible..."
Gao Yuan said, looking at Officer Megu's increasingly confused eyes, he paused for a moment, reorganized his words and said:
"To put it simply, the entire reversing imaging system mainly consists of three modules, namely: photography module, signal transmission module and display module. Generally speaking, through this system, the images that can be seen on the display should be those captured by the camera picture, but if someone tampered with the camera module and the signal transmission module, such as adding a new signal source and slightly changing the communication protocol, the data picture of another signal source can be used to replace the data picture that is finally displayed on the screen. The picture on the screen. And I just took apart the camera to check, just to see if there is such a possibility, and the result..."
Having said this, Officer Megure, who probably understood, showed a solemn expression, while Gao Yuan continued:
"I found something like a small antenna near the output port of the camera! Therefore, I think what the driver just said was that after he heard the scream, the reversing image still looked like the fortune teller. The possibility of distance exists! Someone took advantage of the driver's reversing to make the reversing image not actually show the picture captured by the camera, but other pictures received from the antenna, causing the driver to misjudge The actual distance between the car and the fortune teller caused this incident to occur!"
"What!"
Hearing this, Officer Memu couldn't help being shocked and said:
"Then... wouldn't this incident..."
"It was a premeditated murder! The murderer took advantage of the fact that the fortune teller was used to the bus reversing at this location, so that the fortune teller relaxed his vigilance and did not expect that the bus would actually hit him, making him completely unaware. I was hit by a bus while I was on guard!"
Gao Yuan said seriously:
"As long as the police officers from the forensics department can confirm this technically, they can prove it."
"Really……"
After pondering for a moment, Officer Mumu's expression became very solemn:
"In this case, through that antenna, we should be able to know who has tampered with it..."
"No, the antenna alone can only confirm that someone has tampered with it, but it cannot find the prisoner."
Gao Yuan shook his head and rejected Officer Mumu's idea of directly finding the prisoner, but he still suggested:
"But if the prisoner wants to do this, it means that the prisoner was at the scene at that time. Because the prisoner must confirm that the vehicle started to reverse at that position, and the fortune teller happens to be behind the car, otherwise he cannot complete such a murder. of!"
"In other words... we need to investigate everyone who was on this street when the crime occurred..."
Looking at this commercial street that was a bit narrow but very lively, Officer Megure felt that it was not easy to do things.
And at this moment, looking at Chengzuka Jade, who had found clues but was in a deadlock because of it, Gao Yuan couldn't help but have a faint proud smile on her lips. Then she took out her mobile phone and started to edit a message. Short message.
After a while, just when Gao Yuan faced the current situation and began to think about where to start the investigation, Gao Yuan's cell phone rang.
Subconsciously, Gao Yuan took out his mobile phone and looked at the text message signed "Chengzhong Jade" displayed on the screen. Gao Yuan was stunned for a moment, then turned to look at Cheng Zhong, who was not far away with Xiao Ai and others. Tsuka Emerald——
I saw her smiling and nodding seriously towards me.
So, Gao Yuan clicked on the content of the text message, browsed the text message Chengzhong Jade deliberately sent to him in this way at this time, and then——
"Officer Megure, I know who the murderer is!"
After browsing the content of the text message, Gao Yuan suddenly said to Officer Memu...
…
In "Mycroft Hotel", because the manager Hiroyuki Kanaya fell into the cliff with the car, it was almost certain that the car crashed and killed everyone. When they returned to the hotel, everyone who wanted to call the police remembered their mobile phones. It had already been taken away by the dead Hiroyuki Kanetani.
So, after everyone asked the waitress Hitomi Iwai to lead them, they went to the room of the store manager Hiroyuki Kanaya to look for mobile phones. The scene in front of them shocked everyone present——
I saw that the whole room was in a mess, and all the books on the bookshelf must have been rummaged through and scattered all over the floor.
Everyone's mobile phones, as well as the phones in the room, had all been blown to pieces, and various broken parts fell all over the floor of the room——
"The phones are broken!"
Seeing this scene in front of him, Kawazu Ikuo shouted in panic.
"Who is it...?"
Maria Toda, who followed closely, said somewhat at a loss when faced with the current situation.
"What about the first edition? Is it still here?"
In this regard, seeing that there was no hope of contacting the police by phone, Fujisawa Toshiaki subconsciously asked.
After hearing this, Hitomi Iwai, who first entered the room to look for any communication tools that could still be used, looked around and replied in a panic:
"It's gone...the first edition can't be found anywhere..."
"hateful!"
Hearing this, Fujisawa Toshiaki frowned deeply, gritted his teeth and complained:
"I can't take it anymore! I'm going to drive another car and get out of here..."
"it's useless!"
However, before he could finish his words, Hattori Heiji, who already knew what happened in the house, opened the door with a serious face and said sternly:
"The car in the garage has all the oil in the gas tank and the battery is dead. Now the car can't move at all!"
"How...how could..."
Hearing this, Xiaolan said a little confused.
"So the hotel owner wants to trap us here..."
In this regard, Shimizu Nanako still used a very indifferent tone regarding the current situation, but she asked such a question with a hint of doubt.
"Hmph..."
However, in response to such a statement, Toba Kento sneered and retorted:
"Isn't this obvious? As I expected, the shop owner was killed, right?"
Hearing this, Kogoro couldn't help but roll his eyes at him as he looked like he was willing to be lively and not take things too seriously, while Hattori Heiji agreed with Toba Kento's statement and explained:
"Although I don't know what method the murderer used to speed up the car. But judging from the fact that he destroyed the phone, isolated us, and made the car unable to start, completely trapping us in this hotel..."
Having said this, Hattori Heiji glanced at everyone present with a profound look, and couldn't help but said seriously:
"The murderer seems to want to continue this crazy murderous act!"
"Ah? Who is the murderer? Is he with us?"
Hearing what Hattori Heiji said, Kawazu Ikuo said in a panic, while Shimizu Nanako looked a little worried, looked around at the people present, and took half a step back as if she was a little scared to keep a distance from everyone.
In response to this, Toshiaki Fujisawa, who was obviously panicked and at a loss, said to Maria Toda as if he wanted to vent:
"That's right! You said a lot of bad things about the shop owner. Could you be the murderer?"
But regarding his random biting behavior, Maria Toda looked confused at first, and then after she realized what she was doing, she immediately started arguing with him——
"Aren't you the same!"
As the chatter started, the two suddenly became tense and started to quarrel.
"enough!"
However, in the face of everyone's chaotic behavior, Kogoro finally couldn't help it and shouted to stop their behavior——
"In short, the murderer is someone among us. Although we don't know what his purpose is, trapping us here is equivalent to him catching a turtle in a jar. As long as we work hard to investigate, we will definitely be able to find out the clues of the murderer.
Find him out. So now, please answer my questions!"
With such a calm speech, Kogoro actually took control of the situation for a while. Perhaps due to his status as a famous detective, everyone present chose to follow his arrangements——
"First of all, last night, did anyone see the shop owner after he introduced the event itinerary?"
First of all, Kogoro asked this question——
After all, since meeting the store owner Hiroyuki Kanaya for the first time last night, Hiroyuki Kanaya has not appeared in front of everyone all day today.
However, regarding this issue, everyone looked at each other in confusion. You looked at me and I looked at you. It seemed that no one had seen the shop owner after that.
In response, Kogoro couldn't help but look at the waitress Hitomi Iwai and asked her:
"You must have seen Miss Hitomi, right? After all, the shop owner also has to eat!"
"I haven't seen him either. The master is on a diet recently, so he eats healthy food in his room."
Hitomi Iwai also denied this. Suddenly, Kogoro felt embarrassed and touched his chin, thinking:
"Damn! Isn't it true that the whereabouts of the whole day have been unknown, and I don't know when the person was killed, and the body fell off the cliff and was burned..."
As he said that, Kogoro looked around helplessly and suddenly noticed the monitors installed in every room——
"By the way! There is a monitor! As long as the monitor has captured something..."
"Sorry, that's false."
However, before Kogoro could be happy, Hitomi Iwai poured a bucket of cold water on it, extinguishing the possibility of investigating the time of the shop owner's death through the monitor——
"That is a fake monitor that is set up every year when this event is held to prevent guests from cheating."
"Fake……"
Faced with this situation, Kogoro had no choice but to do so.
"But we still know that the murderer let the shop owner, or the body of the shop owner, get into the car around 3:30, and then started the car. Therefore, it was impossible for me and the five people who stayed in the restaurant for those hours
Take action……"
Hattori Heiji said, looking at Ran, Conan, Toba Kento, Oki Ayako and Iwai Hitomi, and then continued:
"So, the murderer can only..."
"Hey! Doesn't that mean that the murderer was someone among the five of us who was not in the restaurant at the time..."
Regarding such a statement, Fujisawa Toshiaki pointed at himself, Maria Toda, Nanako Shimizu, Ikuo Kawazu and Kogoro who were in the same situation as him with an innocent face.
"Don't count me in."
In this regard, Kogoro said helplessly.
But at this moment, when the atmosphere was slightly awkward, Oki Ayako suddenly came up behind Hattori Heiji and asked in a low voice:
"By the way, did you find the one you were looking for just now?"
"No, none were found."
Subconsciously, Hattori Heiji replied.
"Oh? Humph!"
However, as this answer appeared, Oki Ayako suddenly snorted coldly, and then seemed to be unable to bear it any longer, burst out laughing, which surprised everyone present——
"a ha ha ha!"
"Ayako..."
Quite unexpectedly, Toba Kento looked back at Ooki Ayako who suddenly burst out laughing, and asked in surprise.
"I already know! The tactics used by the murderer... and the decisive evidence!"
After putting away her smile, she took out a cigarette, held it in her mouth, Ayako Oki lit it with a lighter, and then said proudly.
As soon as these words came out, everyone present was stunned.
Among them, Hattori Heiji, who knew that Ayako Ogi reacted like this after asking her questions, realized——
It was her own answer that confirmed something for her, and that was why she said such a thing!
In other words, Oki Ayako knew what she was looking for at that time, and at the same time, the answer to this question concealed a very crucial clue...
But at that time I just wanted to confirm...
Wait a moment!
So, what was that guy thinking at that time?
Suddenly, Hattori Heiji turned his head to look at Conan, and at the same time, the words Gao Yuan said to him before coming echoed in his ears again...
