"Everything is real diamond? Are you sure?" Mizumatsu confirmed very seriously like Kato Kumatsu.

"That... I'm not sure, I definitely can't be sure if it's the laboratory analyst..." Kato Kumatsu joked that he couldn't understand the situation.

"You dare to talk nonsense!" Mizumatsu was really angry.

But basically, since the diamond is real, then the ring must be real... Otherwise, it will become a deep function of the ring. Therefore, some people use real diamonds to imitate a legendary novel to replace it with a ring.

If this happens, it is also at the level that the Tokyo Metropolitan Police Department cannot manage. Shui Mizuki's people now only need to assume that this ring is the real thing and then find the murderer.

So why does the ring carry a ring against the back? Conan would not lie to himself. As long as the deceased is a very nervous person, he will not notice that the ring is against the back. Moreover, the ring is so expensive, it is impossible not to look at it often.

Mizumatsu thought of a possibility, to be precise, what should have thought of at this time...

Secret room technique!

"The last words of death!" A ghost scream came from the plain.

Mizumatsu glanced at Moriya who was shouting and turned to Shiraki: "Have those people finished asking?" Shiraki is usually responsible for understanding the situation on the scene from relevant personnel, so they came over just now either asking or having problems. Seeing Shiraki's expressions of being slow and slow should be the latter.

"This is the inquiry result of the relevant personnel in the case." Sure enough, Shirouki handed a stack of reports to Mizumashima.

The woman among the three people is named Hikuraki, and she is the editor of the magazine published by the works of the deceased Zhuguyi.

One of the other two is called Hiroshima Katsuji, who is a columnist, while the other is a photographer, who is called Chuishui.

The reason why they and Kogoro Mouri are here is because today we will hold a symposium between the famous detective Kogoro Mouri and the famous reasoning writer Maguchi Maguchi, and the talks are recorded in the magazine. (Let Maguchi Maguchi leave the publication just right.) Because the symposium with only two people is planned to be held at 6 o'clock, everyone who did not want to go out early in the morning chose to stay at Maguchi's home one day in advance.

It should be because he heard Conan's words that Shiraki asked them about the ring.

The ring is a huge ring that I think is worth remembering after 100 works of Makura Makura's debut, and only custom-made ones were asked. Kogoro Mori also mentioned that Makura Makura once said that if it weren't for the size of the ring that could not be too over-the-top, he would have planned to inlaid one hundred diamonds.

And everyone confirmed that the deceased liked this precious ring very much, and would occasionally moisten it, and it would be a neurotic who would see the inconsistency of the font sizes in the book, and then furiously got angry.

Regarding the absenteeism, it is temporarily believed that the deceased's death was around five o'clock in the morning. At this time, the Maori family did not get up. Kuraki Kuri was sorting out the manuscripts of other writers in charge, and Mitsuji Izumi was repairing the broken tape recorder, while Kazumizu was shooting the negatives before sorting out.

Among the three people, Mizumatsu was most concerned about the female editor's acupoint Kuriyoro, because according to common sense, if the other party is unaware of drinking the coffee given by someone, the opposite sex is more likely to be more likely.

"Huh?" After reading the information, Mizumaki was about to return it to Shiraki, but suddenly I felt that something seemed a little interesting. The ages of these three people were found similar. Chushui Gang and Kuraki Kuraki was 33 years old, and when Hidao Juezhi was one year older, thirty-four years older.

"Please ask if they are familiar with each other? It seems that they are very old and may be college classmates or something." Mizumatsu ordered.

After the White Bird left, not long after, another bad news came from the direction, namely, there was no suspicious fingerprint on the ring, no suspicious fingerprint on the key, and no fingerprint on the coffee cup at all.

This proves that one of the many assumptions has been proposed. The possibility of giving the poisonous coffee to the deceased and leaving directly, waiting for the deceased to lock the door and taste the coffee and then tasting it is very low. Because the murderer carefully wiped the cup after the deceased's death, he could not find any fingerprints.

Mizumatsu glanced at Moriya, who was still making noise, and walked over: "What are you doing?"

"Police Department! This must be the last words of death!" Sen also pointed to the deceased's hand and said.

Mizumaki looked at the deceased's hand for a while before he realized that Mori was talking about the keys and the upside-down rings with his palms.

"What do you mean?" asked Mizumatsu.

"The deceased's posture is very strange, so it must be when he is dying, and he wants to disclose any information to the person who found the body." Mori said seriously.

"So what? What news is revealed?" Mizumatsu signaled Mori with a bad expression on his face, and felt the key point.

"Well... I don't know yet. Maybe I want to reveal that I committed suicide, so don't involve others?" Senya said after thinking hard.

"I think... you'd better understand the autopsy first..." Mizumatsu was a little helpless. It was a good thing to have someone under his command who likes to use his brain, but this person is a forensic doctor, and it's not right if he didn't do his job well.

Different from Moriya's idea, Mizumatsu felt that these strange things should be related to the secret room technique.

The secret room, keys, small windows, and rings connect the key things together, and Mizumatsu remembered a case he had handled before.

That was the day when Ai Haibara first appeared in his sight. The deceased was a professor at Nanyang University named Masaki Hirota.

It was a secret room case at that time, and the only key was pressed under a notebook in the house.

The murderer was a student of the professor. In fact, he did not solve the case during the process of solving the case. Instead, he found a volume of audio tape for a telephone answering machine in the backyard of the room. The tape inside the tape was wrinkled and obviously pulled, and the student's fingerprint was identified on it.

In his later confession, the student explained his own technique, which was the general idea of ​​pulling out the tape, then passing it through the key and fixing it into a structure that cannot withstand strong pulling. He then called the answering machine and asked the answering machine to help him pull the key back.

Speaking of which, there were also vodkas that cameoed to buy insurance, and a floppy disk containing ATPX, which was later handed over to Wei Xinghu for analysis. Mizumatsu copied a copy of the reference for the antidote research provided by Ai Haibara for Ai.

Taking that case as a reference, Mizumatsu quickly remembered that one of the three suspects had a tape recorder in his hand. If that thing was used as a tape reel, it was more convenient than an answering machine, at least it didn't need to call it inside.

Then, from outside the narrow window, using a video tape to set up a slide to send the key in, and then collect the belt and leave, which constituted a roughly such a method of committing the crime in Mizumatsu's mind. As for the ring, it should have been taken off and taken back, but it was not cautious enough, so it was brought back.

If there is any evidence to support this idea, the cut-off blood stain under the ring should match the tape.

As for how the blood was made, the coroner of Moriya, who worked honestly, finally gave the answer.

There is a wound scratched by a blade on the deceased's cheek that has not been completely healed. It is estimated that the time should not be long before death. From the position, it should be that the shaving was scratched.

In this way, the deceased, Jigu Yigui, got up in the morning and hurriedly shaved his beard in order to pay attention to his image at the symposium. As a result, he accidentally shaved his cheeks. He hurriedly wiped his hands with a ring and wiped his hands briefly. After confirming that he was no longer bleeding, he walked out of the bathroom.

Then someone was already waiting for him in the room, holding a cup of coffee that had been brewed in his room, and handed it to him along with compliments or blessings.

It is mentioned in the information that Zhukou Yigui likes to drink coffee as if he is dependent on caffeine, and he will always refuse to drink it regardless of hot or cold or taste.

After drinking the added coffee, the deceased fell on the bed with a "smacking" sound. The murderer calmly picked up the coffee cup and wiped off his fingerprints, then put on gloves, found the keys on the deceased, and began to arrange the scene...

Since he had found the murderer and method, he began to become familiar with Mizumatsu if he wanted to find evidence.

"The police department asked, they were just friends who graduated from different universities at the same time and then joined the publishing house to work. In fact, they also had a friend who committed suicide two years ago while being the assistant to the deceased." Shirakuen came back.

Mizumatsu smiled faintly, and now he even had the motive for the crime.

"I'm going to call Hiroji Irishima." Mizumaki said that the case can be closed now, he promised.

Naturally, there is nothing to say later. If you mention it by the way, the motive for the crime is actually to avenge the friend who committed suicide two years ago, because the reason why he was "tooked for" suicide was actually because Zhukou Yigui asked to test the feasibility of the crime he had just come up with.

……………………

After sending everyone back early, Mizumatsu rushed into the office and found his cell phone on Nakamura Yan's desk - his office was closest to the door so he was photographed at that time.

It seemed that no one had touched me, Mizumatsu breathed a sigh of relief.

When he walked over and planned to pick up his phone, Mizumatsu accidentally kicked the stool.

Mizumatsu stopped standing, and his expression was very stiff when he breathed a sigh of relief.

After trying it a few more times, and after kicking the stool every time, Mizumatsu had to admit the reality: something was wrong.

Nakamura Yan’s stools will not be placed randomly, and they are placed in a fixed position whether they are on or not, so Mizumatsu was surprised.

After all, when I slap the table in the morning, I definitely didn’t kick the stool or bypass the table, which means Mizumatsu’s mobile phone...

Been moved.

...

"Haci-Haci-" Shuijianyue almost ran to the same line.

Because of the moved phone call, Mizumatsu opened it in despair and saw a new text message that had been read.

The text message seemed to be from Belmode, and it said, "The sniper mission is given to you, the original plan will not change.

If the content of .” is seen by someone... no, the question now is who has seen it.

The first and second series are different from the second and third series, but are not the execution department, but the same positioning, archive registration, archiving, entry, equipment call, etc., similar to logistics support, are all in the same system. Therefore, Mizumaki came and secretly found a system long, Fuji Kong Wuming.

"Isn't this the second-class team leader? Is there anything wrong?" Fujikawa Takeaki greeted with a smile.

However, Mizumatsu felt that this guy's voice seemed to have thorns in it, which was unpleasant.

"It's nothing big. I'll check the surveillance monitor at the door of the second department's office. It seems like the second department lost something today." Mizumatsu said in ambiguously, thinking about when he had offended this person who had nothing to do with all tasks.

"I think it's a big deal? There's no problem, I'll do some registration later and check it casually." Fujikawa Takeaki said very generously.

"It's not a big deal, just register and get rid of it." Mizumatsu was reluctant.

Takeaki Fujikum seemed to be energetic: "Do you want to investigate privately? Let me help you investigate your colleagues?"

Mizumatsu didn't dare to take this conversation. It was a very taboo thing to investigate colleagues privately. If others found out, a big deal would happen.

"It's not that serious. It's just that the lost things are not important or even uncertain. How dare you be so exaggerated?" Mizumatsu discussed with a smile: "For the sake of friendship over the years, I'll just help me check it out, let alone that's the door of my own office."

"We have no friendship." Fujik Takeaki immediately said: "And the office you were in was not your own office at that time, so you are not qualified to check the surveillance casually."

"Enjoy it, don't let me be so embarrassed, okay? I forgot to lock the door and throw things away when I was on the police. It was difficult to do this when it was reported!" Mizumatsu put his arm on Fujikawa Wuming, trying to close the distance.

"Nothing happens!" Fujikawa Wuming was full of maliciousness at Mizumatsu and slapped Kaimizuki in the arm.

"Help help, please invite you to drink tonight." Mizumatsu was still saying.

Fujikawa Takemi thought about it and gestured for three, meaning that he asked for a drink three times.

"Three bottles, no problem?" Mizumatsu said without any mind.

"Get out, you go by yourself!" Fujikawa Wuming said angrily.

"No, no, no, I'm wrong. I'll pay for this if you want to drink gold." Mizumatsu immediately begs for forgiveness.

After begging for mercy, Fujikawa Takeaki as for his willingness to help Mizumatsu, he took him to a room, called out the picture he needed and left.

Mizumatsu stared at the surveillance screen, and his face gradually began to become paler and paler.

Because I don’t know what happened, when I was not around, there were more than ten people entering and leaving the second department office, including Mikako Sato!
Chapter completed!
