Chapter 815

PS：Today a book friend came to Fúzhōu to hang out with me, I took him to eat drunken pride tea oil stir-fried local chicken, and it turned out to be terrible! So today I'm sending a super double chapter of 5700 characters all at once, tomorrow I'll resume two chapters, above」

When the Metropolitan Police Department received the assistance application from Saitama Prefecture Headquarters, Uesugi Muneyuki had just finished dissecting a corpse and returned to the Special Mission Division, he washed his face, hadn't even caught his breath yet, and someone found him.

He heard hurried footsteps coming from the hallway.

"Mr. Uesugi!" Nango Yui's voice came from outside the door, carrying a rare sense of urgency: "Saitama Prefecture Police have formally requested assistance, the Kawaguchi City case, they're asking you to go there."

Uesugi Muneyuki turned off the faucet, shook the water droplets off his hands, and glanced at his face in the mirror.

Half a month had passed, there was no change in expression on that face, but the bluish-black under his eyes had deepened somewhat.

He was a bit tired, otherwise everything was still fine.

Upon hearing the news of Ishihara Mikoto's pregnancy, his grandfather was overjoyed, immediately used his connections at Tokyo University to bring her in for examination, all expenses covered, and immediately gave her 3 million yen as fetal support money, saying if it wasn't enough there was more, and arranged for her to stay in the annex.

The treatment of a wish-fulfillment female protagonist.

"You don't need to worry about this side." Uesugi Kuninori said lightly to Uesugi Muneyuki.

The implication was, you no longer have any use value.

Hey, when you initially wanted an heir you called me Sweetie, now that you have a child you call me Mrs. Niu, right?

Uesugi Muneyuki thought I can't be bothered with you, I'm going to work doubly hard to earn milk powder money for my child!

Ah! poweeeeer!!!

He dried his hands, opened the restroom door, Nango Yui stood in the hallway holding a fax.

"Official document, support request from the Special Investigation Headquarters." Nango Yui handed over the fax: "Not pleasantries, it's serious. Saitama Prefecture Police have investigated for half a month, over four hundred people, not a single match."

Uesugi Muneyuki took the fax, his eyes scanned the text above.

The wording was very official, very restrained, but the urgency seeping through between the lines almost overflowed the paper: "Considering the heinous nature of the case, the wide scope of investigation, earnestly request the Metropolitan Police Department Criminal Investigation Division Special Mission Division to provide technical support."

Translated into plain speech: We can't handle it, come quickly.

He hadn't finished reading when the office door was pushed open from inside.

"I saw it." A woman walked out, holding a copy of the same fax, wearing a dark blue police uniform suit skirt, inside a white silk shirt, hair tied in a low ponytail, revealing a section of fair neck, her facial features exquisite like a porcelain doll, between her brows and eyes a steadiness and sharpness not belonging to a twenty-seven-year-old woman.

This is Uesugi Muneyuki's main wife, Metropolitan Police Department Sakuradamon Lord, Imperial Consort, Hankyo Bridge Ooku Master, Uesugi Minami Police Superintendent exactly!! Vaisravana descended into the world, evil spirits retreat, all things shall eventually crawl before Uesugi, this is, the heavenly summons mouth tooth!!!

"Section Chief." Nango Yui slightly bowed.

Minami nodded, her gaze fell on the fax in Uesugi Muneyuki's hand, her tone flat as if saying what to eat for dinner tonight: "Saitama Prefecture also sent news. The annihilation case in Takasaki City, a family of four, currently no instruction to merge investigations, but the timing is too close, cannot rule out relevance." Uesugi Muneyuki folded the fax, put it in his pocket: "I'll go to Kawaguchi this side."

"I knew you would go." Minami Ojou-sama nodded: "Okada himself is leading the team to go with you, plus Eirina is also coming with you." "Good." Uesugi Muneyuki nodded.

In the office, five people were already ready to depart.

This time Okada Masayoshi is responsible for leading the team, Date Nagamune and Maeda Toshihide are deployed, they three form a group.

Uesugi Muneyuki, Kai Toru, and Ikeda Erena form a group, six people total, departing for Saitama Prefecture.

Ikeda Erena followed behind him, when passing by Minami's side, the two people's gazes met for less than half a second.

Minami expressionlessly nodded once, Ikeda Erena also expressionlessly nodded once.

Hmph! Ha!

No extra expressions. The other Special Mission Division members had long grown accustomed to this strange默契, but Nango Yui each time seeing it would sigh in her heart: These two women, truly damn not ordinary people.

This is probably Minami Clan and her Eirina accompanying attendants?

These three people definitely slept together.

Absolutely!

Nango Yui thought it's exactly like me and Nakamoto Himeta and Nakamoto Suzuka.

How could there be such people who play threesomes all day? Despicable!

Two vehicles departed from Sakuradamon, entered the Tohoku Expressway via the Shuto Expressway Inner Circular Route, heading north all the way.

Uesugi Muneyuki drove his own Toyota Camry, of course Eirina was driving, he rarely drives, Kai Toru sat in the back row, this guy closed his eyes upon getting in the car, unknown if truly asleep or pretending, Uesugi Muneyuki looked at his phone, translating supplementary materials sent by Wuyu County Police. After Ikeda Erena drove steadily, she habitually hung one arm on the steering wheel, the other hand held the wheel, glancing at Uesugi Muneyuki's side profile in the rearview mirror.

"You wanted to go see it half a month ago." Tall Beauty female detective. Not a question, a statement.

"Yeah."

"They didn't let you go then."

"Yeah."

"Now they're begging you to go."

Uesugi Muneyuki didn't respond, he just smiled.

Ikeda Erena smiled slightly, that smile wasn't happy, it was a smile carrying some appreciation, slightly mocking: "So saying, these local police are just face-saving. They insist on hitting the south wall themselves, smashing their heads bloody, before thinking to find someone who can solve the case?" "Eirina Master!" Uesugi Muneyuki called her name, voice very soft, like reminding her not to speak too absolutely: "Local police also have local police's difficulties, if encountering any case they only know to seek help from superiors, next year the local prefectural council will cut their financial budget and personnel establishment."

Ikeda Erena shrugged, changed topic: "What do you think kind of person did it? A woman, two underage daughters, sexual assault, theft, murder and annihilation. This isn't ordinary burglary. Burglars don't usually carry knives, even if they did, they wouldn't use that method to stab the liver, stab the lungs, slit the throat. He's not just killing, he's venting. Sexual crime plus this level of violence, the perpetrator must be a person with extremely distorted psychology."

"Pervert." Kai Toru said with eyes closed, voice muffled, like not fully awake but mind already turning: "Sexual crime and violence highly combined usually points to two types: one is long-term repressed sexual desire antisocial personality, another is someone who has experienced harm from women. The former has higher possibility of random crimes, the latter tends to select specific victim types. You think, Matsumoto Yumi is a forty-one-year-old housewife, Ayano is a seventeen-year-old high school student, Yuka is a fourteen-year-old middle school student—three women of different age groups. The perpetrator isn't targeting a specific person, he's targeting the identity 'female'."

Ikeda Erena glanced at him: "Weren't you just asleep?"

"I was thinking." Kai Toru opened his eyes, gaze firm: "A man who guarded the Imperial Palace won't sleep in the car!" "Hehehe." Eirina snorted disdainfully, but said nothing.

The Imperial Palace case was Kai Toru's career peak, also made him famous worldwide.

"Don't purely think along this line, there's another factor, that this is similarly a home invasion robbery." Uesugi Muneyuki thought, chin in hand: "But the problem is, if it's a random antisocial personality, how did he get in? Matsumoto residence had no broken lock, no pried window, victims opened the door for the perpetrator without violent intrusion, a single woman with two underage daughters, would open the door for what kind of stranger? Not likely."

"So Wuyu County Police have insisted it's an acquaintance crime." Ikeda Erena said.

"But they investigated half a month, over four hundred people, not a single match." Kai Toru's voice carried confusion: "If it's an acquaintance, how could they completely disappear from the social circle? This doesn't fit logic."

The car interior instantly fell into silence.

"Have you considered," Uesugi Muneyuki thought for a moment, gaze fixed on the road ahead, voice not loud but each word clear: "Wuyu County Police from the start assumed a premise—the perpetrator let victims open the door through some 'reasonable' way. And this premise again deduced a conclusion—the perpetrator must be someone the victim knew."

"According to common sense, that's indeed so." Ikeda Erena turned the wheel, the car merged into the left lane, overtook a slow truck. "But if this premise itself is wrong?" Uesugi Muneyuki said.

The other two people in the car simultaneously looked at him.

"Not an acquaintance can also make victims open the door." Uesugi Muneyuki said: "As long as the perpetrator disguises as some identity people cannot refuse. Delivery person? Delivery persons have already been investigated by police, what if it's a police officer knocking? No, Matsumoto Yumi didn't call police, police wouldn't come uninvited. Neighbor? If it's a neighbor, she should recognize them, then it's back to the 'acquaintance' circle."

"So this is a 'non-existent' perpetrator." Uesugi Muneyuki finally concluded: "Still need to wait for our autopsy to say." "Yeah!"

One hour later, the Wuyu County Police Headquarters arrived.

The Forensic Medicine Teaching Room is on the third floor of the county police headquarters, a room that has had its air conditioning running year-round and is filled with the mixed smell of formalin and disinfectant. When Uesugi Muneyuki arrived, Matsumoto Yumi's corpse had already been moved to the dissection table, covered with a white cloth.

The forensic pathologist in charge of this case is a balding man in his fifties named Yoshimura. Seeing Uesugi Muneyuki enter, his expression was like he had let out a sigh of relief, yet also seemed somewhat tense.

"Chief Uesugi, long admired." Yoshimura bowed: "The corpse has undergone preliminary examination, but the detailed…… I think you might prefer to do it yourself. We have already performed freezing and preservation treatment……"

Uesugi Muneyuki nodded, without exchanging pleasantries, and gestured for everyone to leave.

He took off his coat and handed it to Nango Yui, rolled up his shirt sleeves, put on gloves, and lifted the white cloth.

What met his eyes was shocking.

Matsumoto Yumi's corpse was more mutilated than he had anticipated.

There were two stab wounds on the neck, four on the chest, and seven on the abdomen—each one not the three previously reported, but seven. One of the knives had pierced through the gap between the ribs, penetrated the diaphragm, and reached the lower edge of the heart.

Her face was swollen and deformed; the fracture of the right eye socket was still clearly visible even after death. Three teeth that had been knocked out were neatly placed in the evidence bag—was it the killer who picked them up from the ground and put them in, or were they naturally shed and then discovered? The report did not specify.

Uesugi Muneyuki's gaze lingered on her face for a few seconds, then moved to her hands. Her fingers were slender, her nails neatly trimmed, and on her left ring finger there was a faint trace—one where the wedding ring had been removed.

The report mentioned that among the missing jewelry at the scene was a platinum wedding ring, which should have been taken by the killer.

Only Matsumoto Yumi's corpse at the scene showed any reaction; the other two daughters had completely lost the opportunity of the Death Soul Contract. Uesugi Muneyuki hesitated for a moment, but still decided to immediately activate the Death Soul Contract—although he himself still did not fully understand the situation and might miss key issues, there was no way to delay any further.

【Matsumoto Yumi, I am Uesugi Muneyuki, I want to ask you a few questions—how exactly did you die? Who killed you? What method was used to knock on the door?】Uesugi Muneyuki asked in a warm voice.

The temperature in the room seemed to drop by one degree.

Then that voice came.

It did not come from the ears. It surged up from the depths of consciousness, like water seeping out from underground—slow and unstoppable.

The voice of a housewife, carrying the local accent of Wuyu County—one that lies between Tokyo and Gunma, with a slightly muffled ending tone—trembled, broke, as if crying, as if screaming.

Uesugi Muneyuki's forehead veins bulged taut.

Indeed, this housewife began to transform into a cursed grudge.

【A woman…… a woman…… knocking on the door……】

Uesugi Muneyuki's fingers twitched slightly, gripping the edge of the dissection table.

Woman???

【Is it a woman? Is it a woman who knocked on the door?】Uesugi Muneyuki's thoughts raced: 【Do you know her?】

【I don't know…… I don't know her, but she…… she looked very normal, she said she was selling insurance…… At around nine o'clock in the evening, I was about to let the daughters take a bath, the doorbell rang, I looked out through the peephole, and saw a woman, about thirty years old, wearing a suit skirt, holding a file folder in her hand, looking very proper. She pressed the doorbell, smiled at the peephole, and said, "Is this Mrs. Matsumoto? Sorry to disturb you so late, I am from Nippon Life, I have some documents that need your signature……】

Woman!!!

Uesugi Muneyuki's heart stirred.

It really is a woman!! Indeed, it is a woman!!

Late at night, a woman knocks on the door, saying she needs help—her car broke down, she got lost, she was being followed—any woman living alone or with children would be more inclined to open the door for a woman!

This is not discrimination; it is common knowledge in social psychology.

The threat level of a female visitor at the door is far lower than that of a male, and the victim's defense mechanism will not be triggered.

It is said that before, people have lured young women or housewives to open the door by disguising as infant cries or cat calls, then taking the opportunity to break in and commit murder! But there is one point that doesn't make sense.

The other party clearly knew her, and even knew her surname—even if there was a house number…… but this feeling does not seem like that of a stranger.

【Do you know who she is?】Uesugi Muneyuki pressed on.

【I don't know her; ……】

【Then why did you open the door for her? Didn't the community safety course teach you not to open the door for strangers?】Uesugi Muneyuki said, somewhat flustered: 【I hesitated for a moment, but she is a woman, and…… and she looked so normal, so polite. I thought, just signing a document would do, it would only take a minute. I opened the door.】

Uesugi Muneyuki closed his eyes.

【Then what happened?】

【Then she first came in and said a few words, introduced housing insurance, I said I didn't need this, she begged me to say listening wouldn't hurt, she didn't insist on selling this insurance, but at least wanted to prove she had promoted it to someone, otherwise her supervisor would fine her, then she said our Japanese society discriminates against women, women in the workplace naturally find it difficult, I felt somewhat sorry for her, so I poured her a cup of water and listened to her say a few words, then she mentioned three-year and five-year plans, intending to introduce ten-year insurance when suddenly she discovered something forgotten outside the door, said she needed to go get it, and asked me to wait inside……】【Then you just sat on the sofa, letting her go open the door?】Uesugi Muneyuki understood.

【Yes, then when she returned, there were two people behind her. Two men, I hadn't even reacted yet, they just pushed the door open. That woman put away her smile, walked past me from my side, as naturally as returning to her own home. She turned her head and glanced at me once—that glance…… I still remember it to this day, in her eyes there was no emotion at all. Not hatred, not anger, not greed. Nothing. Just…… just as if in her eyes I was not a person, but an object.】

Uesugi Muneyuki opened his eyes, looking at Matsumoto Yumi's face, beaten into deformation.

The face of the soul is far more complete than that of the corpse—no bruises, no fractures, no bloodstains.

She looked like an ordinary housewife, in her early forties, with fine lines at the corners of her eyes, lips somewhat chapped, and in her eyes was that immense, indescribable sorrow that words cannot convey.

【They ransacked my home, took my money, took my daughter's lucky money saved for years, took my wedding ring. Then……】【Then they went upstairs, my daughters…… Ayano…… Yuka…… I heard them calling…… I couldn't get up…… I couldn't get up…… my whole body was covered in blood…… I heard Ayano shouting "Mom"…… then she stopped shouting…… then Yuka also stopped shouting……】Uesugi Muneyuki's hand relaxed from the dissection table, hanging at his side: 【In other words, they were working together?】

【She stood there the whole time, watching.】Matsumoto Yumi's voice became hollow and weak: 【She watched everything those two men did. She watched them ransack my home, watched them…… watch me, watch my daughters…… she stood there, arms crossed, like waiting for a bus.】Uesugi Muneyuki took a deep breath and slowly exhaled.

【Thank you. Thank you for telling me this. I will find a way to track them down.】

Matsumoto Yumi's soul looked at him, and in those eyes suddenly welled up tears—not liquid, but a light, a kind of light only Uesugi Muneyuki could see.

【Please.】She begged with a bitter smile: 【Please don't let them harm anyone else.】

【Also, I hope you tell everyone, don't because of my case give up helping others…… life in this world is not always satisfactory, some people need help, don't learn to be indifferent, this world should not be like this……】

Then she disappeared.

Uesugi Muneyuki stood in place, motionless, standing for about ten seconds.

Then he turned around, took off his gloves, and walked to the sink to wash his hands.

The faucet splashed loudly, he washed very carefully, from fingertips to wrist, every finger gap scrubbed with a brush.

Woman, tricking open the door.

Two men, following behind and entering.

Home invasion, theft, violation, murder.

Random crime? For money? For lust? For revenge? Or is it an antisocial personality serial killer?

Uncertain.

Moreover, Matsumoto Yumi did not know this woman and those two men at all, but the other party seemed to know her.

This is the most difficult situation, meaning that Uesugi Muneyuki's current abilities and the knowledge he possesses are completely unable to break through.

Acquaintance as the perpetrator?

The entire family, social circle, and neighborhood network of over four hundred people were all investigated by the Wuyu County Police, and each one was ruled out as a suspect.

Stranger as the perpetrator?

However, Matsumoto Yumi does not know this woman, yet the woman seems to know her!

So, is there a situation where the other party knows Matsumoto Yumi, but Matsumoto Yumi does not know her, she is not in Matsumoto Yumi's acquaintance circle and thus would not be found by the police, yet she could still learn about Matsumoto Yumi's home address, name, and family situation?

Uesugi Muneyuki realized he had fallen into a dilemma.

He discovered that he actually had no way to find this nonexistent killer.

But without a doubt, the Kawaguchi Police Station may have overlooked this possibility, focusing all their efforts on investigating male acquaintances. But if the person knocking on the door was a woman, the victim's act of opening the door would no longer require the condition of "acquaintance." The entire nature of the case would then change—no longer an acquaintance committing the crime, but someone using a female identity as a breakthrough point, having premeditated the crime!

Wait! Uesugi Muneyuki suddenly thought of something.

Could it be?!?!
