Shirakawa walked out of the apartment and happened to meet Chiyuki Mei.

"Good morning, Mei Yi-san."

"Good morning, Kuraki-kun."

The two got into the elevator, and this time, in the elevator, they met not only Yuko-sensei upstairs, but also Miss Kyoko.

With long flaxen-colored curly hair, wearing black-framed glasses, wearing a white shirt and a black hip-wrapping skirt, Yuko-sensei is obviously not amazing, but she is very attractive, and the iconic tear mole under her left eye gives her a unique charm.

Even if she stood next to Miss Kyoko, who had the temperament of a cold queen, she did not lose her original style.

Miss Kyoko, who is tall and delicate-looking, wore a simple royal blue one-neck dress today, which sets off her fairer skin and outstanding temperament.

Miss Kyoko doesn't seem to like wearing high heels because of her height.

Shirakawa guessed that her feet should look good.

Compared with Teacher Yuko and Miss Kyoko, Qianxue Meiyi has a little less mature charm and more girlish innocence.

She is wearing a standard school uniform, white stockings and black loafers, her long black hair is combed into a downward double ponytail, and she has a handsome little face like her first love, revealing a strong youthful atmosphere.

Since she deliberately checked the weather forecast when she went out in the morning, she also brought a transparent umbrella.

The three belong to a completely different type of beauty, but they all give a pleasing feeling to the eye.

Bai Chuan has a legal Lori hidden at home, and when he sees them, he has a feeling of pure appreciation.

This is probably the legendary time of the sage.

"Good morning, Shirakawa-san, Mei-san."

Ms. Yuko greeted the two with a smile, while Miss Kyoko looked at Shirakawa with a blank face, her eyes seemed to be looking at a stranger, and she seemed to be recalling an old acquaintance.

Shirakawa first greeted Yuko-sensei, and then smiled and nodded at Miss Kyoko,

"Miss Kyoko early, did you go to work so early?"

"Hmm."

The cold Miss Kyoko also nodded slightly.

If it is a man with a strong competitive spirit, I am afraid that he will be stabbed by her indifferent performance.

Fortunately, Bai Chuan is not such a man, his gaze returned to Qian Xue Meiyi, and said with a smile,

"Looks like we can take Yuko-sensei's ride today."

Compared to Yuko-sensei's ride, Chiyuki Mei still prefers Shirakawa's back seat.

But she didn't say it, feeling that she would destroy her image in Kuraki-kun's heart.

Kuraki Yuko glanced at Shirakawa resentfully, her hitchhiker has always been open for him, but he has always been reluctant to sit, why did he suddenly open up today?

When the elevator passed through the lower floors, several office workers were crowded in one after another.

But there was not much communication between them, and in this apartment, like most people in the city, they were just strangers dressed as neighbors.

Arriving on the 5th floor, Ueo Masumi took his mother's hand and squeezed in.

"Hey, there are so many people today."

Ueo Masumi sighed, and saw the young Shirakawa in the corner, and Chiyuki Meiyi, who was protected by Shirakawa.

"Big sister, big brother are all here, Mom, what a coincidence."

Ueo Masumi immediately greeted the two politely, she combed her ball hair today, and wore the same hairpin as the intellectual Mrs. Ueo.

Of course, it may also be that she asked her mother to wear such a childish hairpin.

The sweet-looking Mrs. Ueo was wearing a white dress, and her slightly haggard face had a faint dark circle under her eyes, probably because she didn't sleep well last night and stayed up late to write.

"Good morning, ma'am."

Shirakawa said to Mrs. Ageo.

"Good morning, Kuraki-kun."

Mrs. Ueo smiled in response, and quietly glanced at the women around him out of the corner of her eye.

The elevator reaches the B1 floor.

Shirakawa and Chiyuki Mei sat on Yuko Kuraki's white Honda.

"Shirakawa-chan, I've been taking leave lately, have you missed the course, do you need my sister to help you with your tuition?"

Yuko Kuraki, who was driving, asked.

"No, I read Mei Yi's notes, and they are very detailed, and there is no problem."

"Mei Yi is indeed a good student who studies hard."

"No, no, Yuko-sensei, I'll keep trying."

Qianxue Yayi was a little embarrassed in the face of the teacher's praise.

The three of them chatted as the car drove toward the school.

After the class, Shirakawa had just walked into the club room when he was called away by a phone call from Saya Shiraki.

When Shirakawa walked into the Metropolitan Police Department's office area, officers were discussing a recent murder.

Shizuji Nakayama holds two transparent plastic bags with daggers of the exact same style.

"This is the murder weapon we found, but the problem is, there is only one wound, why did two murder weapons appear, and the fingerprints on the murder weapons were not the same?"

An experienced veteran police officer said, "What does the medical examiner say? ”

"The forensic autopsy found that there was a fatal wound to the chest of the corpse, which should have been fatal, and the two daggers matched the wound, and the blood of the deceased was also detected on them."

Shizuji Nakayama said.

"I think it must have been done by the deceased's mother, who used to beat or scold the deceased at home, and had a very bad personality."

"Even so, it's impossible to kill your own son."

"No, the deceased is not the mother's own son, he was adopted, or the deceased's father asked for adoption, since he came to the house, the deceased's mother has been looking at him unpleasantly, which is also the reason why the deceased's father was sent to a nursing home after his death, maybe that's it, the mother hated him, so she did it."

"No, I think it was the deceased's wife who did it, and the wife found out that the deceased was cheating, and the motive for killing was more obvious."

"Generally, wives don't take such an extreme way when they find out that their husband is cheating, like my wife just talks to me calmly and hopes that I will change my mind."

The officers were talking about the case.

Until Shizuji Nakayama saw Shirakawa, who was about to be taken to the lounge, and suddenly called out Shirakawa's name, "Kuraki-kun!" Wait a minute. ”

Shirakawa turned his head and looked at Shizuji Nakayama who was trotting over,

“？”

"Kuraki-kun, help me analyze it."

Shizuji Nakayama raised the transparent plastic bag in his hand and continued,

"The day before yesterday, someone reported that a male corpse was found in the wasteland of Arakawa District, and after forensic monitoring, it was determined that the murder weapon was a dagger, and the fatal wound was a knife wound in the chest.

The dagger was stained with the blood of the man's corpse, and it was judged that this should be the murder weapon.

But the fingerprints on the two murder weapons are completely different.

After testing, one fingerprint was that of the deceased's mother and one was that of the deceased's wife.

The deceased's mother is now in a nursing home, and the two are not actually related by blood, and the victim is a child who was adopted that year.

The wife is a full-time housewife, and the relationship with her mother is very poor, and the two will never commit crimes together.

Moreover, both had a motive to kill.

Because she complained that her son sent her to a nursing home, her mother often scolded her son in the nursing home, thinking that he deserved to die and should not have adopted this white-eyed wolf in the first place.

The wife was found by her because of her husband's recent cheating...

The medical examiner judged that the murderer was killed by a knife, so there could be no second murder weapon, so only one of the two murder weapons was real, which determined who the suspect was, and it was really difficult for me to judge.

So, Kuraki-kun, which of these two daggers is the real murder weapon? ”

Shizuji Nakayama briefly described the origin of the two daggers and the circumstances of the case.

Shiraki Saya took advantage of this gap to go to the tea hall and pour two cups of coffee over and handed one to Shirakawa.

Shirakawa looked at the two daggers, and with so few clues, he had no choice but to use the identification technique.

[Item: Dagger]

[Identification result: A blood-stained dagger, Airi Muroi stabbed her husband in the chest with it, can the blood that flows out calm her anger?] 】

[Evaluation: Don't take a woman's anger lightly.] 】

[Item: Dagger]

[Identification result: A blood-stained dagger with Kaji and Utako's fingerprints on it.] 】

[Rating: ......]

Shirakawa pointed to the plastic bag that Shizuji Nakayama was holding in his left hand,

"This is a murder weapon, and my wife is a suspect."

"Why?"

Shizuji Nakayama and Saya Shiraki spoke almost in unison.

Shirakawa explained,

"A knife kills, this requires a considerable level, guessing that the wife should be a doctor or a cook before becoming a housewife, and she has been a housewife for many years, and she is often inseparable from knives, she gave up everything for her husband, but her husband cheated, which caused her strong dissatisfaction, so she had murderous intent."

"Kuraki-kun, the victim's wife was indeed a famous chef in the past! After getting married, I never went to the hotel to cook again, and I have been working as a full-time wife at home. ”

Shizuji Nakayama said in great surprise, he didn't expect Shirakawa to be able to deduce such accurate information with a single sword.

"But the victim's wife, Airi Muroi, has an alibi, the time of the deceased's death is between 10 and 11 o'clock in the evening, at this time, the deceased did not go home, but his wife Airi Muroi had already returned home at 9 o'clock, and because of her husband's affair, she drank a lot of alcohol, and almost did something indecent to the male neighbor, the male neighbor remembers very clearly, it was he who helped send Muroi Airi into the house, if it wasn't for the urging of the male neighbor's wife, maybe something happened to the two."

"The male neighbor also heard Airi Muroi crying and complaining loudly at 10 o'clock about how her husband was worthy of their original vows."

Another police officer added.

"The alibi was fake, the crying was recorded in advance, and Airi Muroi also deliberately acted drunk and wanted to insult the male neighbor, just to deepen the impression of the male neighbor and testify to her subsequent alibi, in fact, she quietly left shortly after returning home."

Shirakawa said calmly.

Saya Shiraki was drinking coffee and didn't understand why Shirakawa was so sure, and the victim's wife forged an alibi, so she asked directly,

"Kuraki-kun, why?"
