"Mizuma, is the case done?" In the Metropolitan Police Department, Mizuma met the Twilight Police Department.

"yes, it's finally done, and the officer hasn't gone home yet?" asked Mizuma, and it was already one o'clock in the morning.

"Well, I've had some headaches lately, so you'll be in the manager's office in a moment. The Dusk Police Department said.

"Oh yes, the steward hasn't come home either. Mizuma Moon agreed.

The arranger settled the interrogation of Kawarai, and after a while of the transcript after Enomoto Sugito and Enomoto Azusa came, Mizuma Moon knocked on the door of Matsumoto's office.

"Come in. “

Mizuma pushed the door in and found that not only the Matsumoto police were there, but also the Twilight Police Department was inside.

"Mizuma, I've had a great time lately. As soon as Mizuma closed the door, Matsumoto came to a cool voice.

Mizumatsuki chuckled in her heart, the previous few times she came to the manager's office to talk, she basically asked him to sit down and talk, but this time she suddenly opened her mouth as soon as she closed the door, and it was in a cool tone, which was definitely not a good thing.

"Also...... Well, I've been pretty busy lately, but it's been a bit of a bitter end. Mizuma replied.

"I also think you're quite busy, you weren't busy enough for your work and robbed the case for the third department?"

"That...... I just feel that the case is not simple, and I am a little worried if I don't handle it myself...... And let me guess correctly, the suspect found out at the beginning of this case is not the real murderer!" Thanks to the fact that this case happened to be a complicated case involving a detective, Mizuma Moon still had some reason to explain his behavior of robbing the case.

"Smack!" The sound of slapping the table, Matsumoto's face darkened a level, and even the scar on his left eye was red: "Let me ask you, when will there be a rule in the Metropolitan Police Department that cases can be fought for at will!"

It turned out that because of this, Mizuma Yue knew it, and very simply lowered his head and admitted his mistake: "I was wrong! I'm sorry! I admit punishment!"

"Okay, okay, Mizuma didn't deliberately make trouble, he also did it for the correct detection of the case!"

Mizumayue's lowered head and eyes changed, the standard of these two people is one singing white face and the other singing red face, there is a ghost in this matter.

"Well, since you kid likes to be busy, let's make you a little busier. After a while, Matsumoto suddenly said as if he had a good idea.

"Please. "Shui Jianyue has a posture of listening to and respecting.

"I remember that you had a lot of experience in dealing with old cases, right? Sato's case was handled well. Matsumoto said slowly.

Mizuma Tsukilen was stunned for a moment, and then realized that this Sato was referring to Miwako Sato's father, Sato Justice.

It was also this stunned that made Mizumatsuki lose the opportunity to defend herself, and an old-colored file bag was placed on the table.

"What is this?" asked Mizuma.

"This is a serial murder case that shocked society 20 years ago, and the prosecution period is still a week away. The Twilight Police Department explained.

"I remember that the prosecution period was fifteen years?" Mizuma asked, saying that Miwako Sato's father's case was because the prisoner had been abroad for five years, so it was a twenty-year period before he could continue to pursue it.

"You can take a look at it first, the reason why it is still in the prosecution period is because the murderer did another case fifteen years ago. The Twilight Police Department explained.

"What is there to worry about during the prosecution period, first find an unsolved case that has not been solved in recent years, find a few reasons to make up a few reasons to merge the case first, won't the prosecution period be extended, and when the murderer is found, he is looking for his fault, as long as he has done other things over the years, he can be liquidated together. Mizuma Yue picked up the file and made a joke by the way.

Stare at......

"Joke ......" was stared at by the eyes of the two bigwigs, and Mizuma said curtly.

"Hmph!" "Hurry up and read the information!"

"Good, good. Mizuma Yue opened the file and looked at it one by one.

"Japanese sword...... Doctor...... Professor...... Kitchen knife...... The lawyer ...... "Mizumayue looked at it one by one.

The case can be divided into five cases, three of which are burglary murders, and the other two are that a police officer found that the person was suspicious and was killed by the murderer, and the other was that the Matsumoto police officer who found the murderer fought with the murderer, and Matsumoto police was left with a scar that ran through the upper and lower eyelids.

"Because there was a lot of trouble back then, the matter that is about to reach the prosecution period will be noticed by the media, and the investigation of this case will soon be collectively mobilized, just let you see it in advance and will not let you fight alone. It seemed that Mizuma Tsuki's expression was too serious when he looked at the information, and the Twilight Police Department comforted him.

"Do you mind if I take it back and look at it slowly?" asked Mizumatsuki as she picked up the file bag in her hand, a little unable to concentrate under the gaze of the two frozen people.

"Take it, but watch the time, it's the last week. The Twilight Police Department instructed.

"Wait. The Matsumoto police officer called out to Mizumatsuki, who had already turned around: "Take this together." He took out a file bag from the drawer and threw it to Mizuma.

Catching the file bag, Mizuma Yue looked curiously at the same old but unsigned file bag: "This is ......"

"A supplement to this case, there are some things that have been set as covert. Matsumoto said.

"I see. Mizuma Yue nodded, because to prevent some imitators from confusing their perspectives, and to avoid some important characteristics in the process of handling the case to let others know, this is the hidden content.

The file bag with hidden contents was smaller than the previous one, and Mizuma Yue directly stuffed it into the previous one, took it in his hand and left.

"Police...... Is he okay with Mizuma?" asked the Dusk Police Department hesitantly.

"Is that your trained subordinate who doesn't have confidence in himself?" Matsumoto quipped.

"Mizuma, this kid...... I don't understand. The Twilight Police Department shook their heads.

Matsumoto was silent for a moment and said: "Dead horses should be live horse doctors, there is only one week left, of course, I don't want to give up, I can't put my eggs in one basket, and I can't do it in an iron basket." “

……

There's still a week to go, Mizuma Moon thinks so, there is still one day left for Miwako's birthday on the weekend, so there is no need to rush.

Glancing at the office of the third department, Miwako Sato still has some work to do, unlike Mizuma Tsuki, who likes to directly ask people to help him do his work, Miwako Sato has a posture of doing everything herself.

Because he wanted to wait for Miwako to go back together, Mizuma went back to his office first and looked through the documents just now.

"Police Department, what is this?" asked a police officer on night duty who was bored when he saw Mizuma Moon flipping through the information.

"Take a look at the case in a few days. Mizuma replied casually, not noticing the ambiguity in his words.

"Ah......" The police officer who asked the question turned into a thunderous toad, with a mouth bigger than a hippopotamus, and didn't ask anything.

As a result, after Shui Jianyue finished reading a case, there was another midnight rumor circulating in the Metropolitan Police Department.

"Have you heard? The head of the second line, Mizumatsu, can predict in advance the cases that will occur in a few days!"

And the rumor's owner, Mizuma Tsuki, has not yet realized this, and he is now re-listing several cases on a blank piece of paper.

In chronological order, the first thing is a burglary murder case that occurred twenty years ago, the victim was called Jiji Fangkawa, who was fifty years old at the time of the murder, a doctor by profession, and the murder weapon was a Japanese knife collected in his home, and the murder weapon was taken away.

The characteristics of the case are that the deceased's back was engraved with a knife with a large capital letter "e" The black and white photo of the file from twenty years ago, but the color could not change the bloody feeling that the scene gave Mizumatsuki.

The second incident occurred two days after the first one, also a burglary murder case, the murder weapon was the same Japanese knife, and the victim was Atsunori Maida, a professor at the Department of Science and Engineering of Toto University, 42 years old, with an "S" engraved on his back.

Mizuma stared at the photo for a while, and wrote on the paper the evaluation of "skillful knife skills, mellow turns".

And the third case ...... Mizumatsuki's breathing was disordered.

In the third case, the police officer who investigated the case at the time, the Morimura Police Department, found that a car appeared frequently at the residence of the two victims, so when he saw the car, he stepped forward to interrogate it, but was hit by the other party's car directly, and unfortunately ...... He died in the line of duty, and after his death, two additional levels of police were added.

Taking a deep breath, Mizuma looked at the fourth case.

The person who personally experienced the fourth case was Matsumoto Police Inspector, who met the prisoner at the dock at that time, but due to his lack of experience, he was discovered by the prisoner in the process of reporting to the Metropolitan Police Department, and the prisoner attacked Matsumoto Police Station with a Japanese knife, and after leaving a scar on Matsumoto Police Officer's left eye, Matsumoto Police Station snatched the opponent's Japanese knife during the struggle between the two people, and slashed the other party in the back.

However, because he was injured in one eye, Matsumoto did not know whether the knife was cut in the chest or in the back, only that it was a horizontal knife.

In addition, when Matsumoto Police found the other party, the time was evening, the weather was cloudy, the dock lights were dim, and the other party was wearing a hood and an obviously fake beard, Matsumoto Police had no impression of the other party's characteristics at all.

Perhaps because of his injuries, the killer was silent for five years, and then committed his last crime fifteen years ago.

The deceased was a lawyer, thirty-four years old at the time, named Nabii Susu, and Mizumatsuki felt that this name was the material for the back of the pot when he heard it.

It was still a burglary, and the murder weapon was a kitchen knife from his own house, perhaps because the murderer had confirmed that this was the last case, or because he didn't look down on inferior weapons like kitchen knives, the kitchen knife was left at the scene.

The deceased is still engraved on the back of the letter, which is one of the main reasons why this case is considered a continuation of the serial murders of twenty years ago.

Taking two deep breaths, Mizuma Yue opened the smaller secret folder again.

"let-it-be" Mizuma narrowed her eyes, in the two cases twenty years ago and in the case fifteen years ago, someone near the scene witnessed a strange person whistling, the tune was the Let-It-Be of the Beatles, and this incident was also one of the reasons for the merger of the cases fifteen years ago.

"Tsuki-kun, are you still there?" Miwako Sato's voice came from outside, and Mizuma Yue immediately agreed, "I'm here!" and then stood up and hurriedly packed up the materials and stuffed them into the file bag, completely unaware that he dropped a piece of information when he stood up.

The way home was no different than usual, except a little later than usual...... No, it was hours earlier, and nothing worth describing had happened.

……

Because the day before was equivalent to working overtime until the evening.,The next day, Mizumatsuki only needs to go to the Metropolitan Police Department in the afternoon.,After getting up in the morning, Mizumatsuki called Miwako to say good morning.,Reading the newspaper while eating breakfast.,Suddenly on a whim, I turned on the TV for a long time.。

Coincidentally, the anchor of the morning news program is an acquaintance of Mizumatsuki, and Shui has no mercy.

"A murder case that occurred 20 years ago has not been solved so far, and seeing that the prosecution period is approaching, have the police given up? For details, please see TV Tokyo's Rule of Law Online ...... at 10 o'clock today" Sure enough, the case from 20 years ago has been turned over and the body has been whipped, and Mizuma Yue was a little unappetized by this news, and she didn't bother to change the channel, so she simply ignored her and concentrated on dealing with breakfast.

But this case is really not an ordinary tricky, first of all, the scene twenty or fifteen years ago has long been out of protection, Mizuma Tsuki's most thoughtful evidence collection has been completely useless, and the murderer's 'portrait' is also very incomplete, in addition to knowing that the gender is a man, I only know that I was cut by the Matsumoto police officer with a horizontal knife wound, but I don't even know whether it's in the chest or in the back, and I can only identify the suspect after narrowing the scope, and it has no effect at all in the suspect search stage.

Mizuma dipped her finger in some green tea and drew on the table.

e、s、…… What does this mean? Mizuma felt that these three letters were not very rare, as if they had appeared in places where he often saw them.

Would you like to go to the library in the morning and borrow an English dictionary to look it up......? I just don't know if it's important for him to investigate the case or to ask Miwako to go out.

"Let's play an anecdote.,Miss Zhuangtang Hutao, the only daughter of the Zhuangtang Group, won 100 million yen in the lottery ticket she bought in her spare time.,Miss Hu Tao, who didn't need the money, publicly stated that she wanted to give the money to a lucky boy......" Unconsciously, the sound of the TV came into Mizuma's ears again, but it didn't seem to be the nasty news, Mizumayue turned her eyes to the TV.

"That's a man who saved her in her childhood, and he has a big horizontal scar on his body! What the hell is going on? Please listen to the detailed report for you later, if you also have a large horizontal scar on your body, maybe you should listen carefully!" Shui Wuna winked mischievously in the TV.

"Poof!" Mizuma Moon squirted out the green tea she had just drunk and sprinkled it evenly on the table.
