The study door is open.

A box labeled "Large Format Hardcover Book" was placed in front of the door.

"Sir, Detective Maori is here."

Okuhira Eiko shouted to Okuhira Kakuzo, who was squatting in front of a pile of books, sorting something, and then bent down to check the box on the ground, "...Is this an express package? Why hasn't it been opened yet?

"

"Eiko!"

When Okuhira Kakuzo saw this, he immediately yelled: "No one is allowed to touch it before I decide where to put it!"

When Ye Gengyi visited yesterday as a friend of Ouhei Takugo, he did not have the opportunity to visit the study. At this time, seeing the books in the room and Ouhei Kakuzo wearing gloves who seemed to be sorting, he could understand some of the collection.

Of course, he understood the speaker's unique hobby. After hearing what the other person said, he couldn't help but sneered:

No one can touch it, not even the courier.

On the side, Eiko Okuhira was inexplicably scolded, especially in front of guests, and her expression was obviously a little unhappy.

However, she did not have an attack on the spot. She just turned towards the short old man who had come to the door angrily, repeated that Detective Maori is here, turned around and left directly.

"Mouri...Detective? Ah! You are the famous detective Mouri Kogoro."

Okuhira Kakuzo was startled, then realized what was happening, and quickly moved the box blocking the door. While inviting the two of them in, he looked at Ye Gengyi doubtfully.

"I am the assistant of Detective Maori." Ye Gengyi introduced himself.

"Oh, please come in, please come in quickly..."

Okudaira Kakuzo nodded and shouted towards the corridor: "Hataro! The guests are here, hurry up and make coffee!"

"master……"

After waiting for more than ten seconds, the housekeeper Segawa Hatakero came trotting over and said with an apology: "I'm sorry, sir, because we have run out of creamer. You see, otherwise..."

"Idiot! How can you give guests that kind of thing!" Kakuzo Okudaira growled, "Then make me some tea quickly!"

Ye Gengyi: "..."

It's okay, I want to drink coffee...

Of course, because the purpose of his coming here was not to drink coffee, he didn't say this.

Immediately, Okuhira Kakuzo quickly returned to the study and motioned for Ye Gengyi and Mouri Kogoro to sit down.

This turbulent look and the eager look on his face made Kogoro Mouri just exchange a few simple greetings and then go straight to the topic and understand what happened.

Okuhira Kakuzo took out the photos he had prepared in advance from a photo album placed on the coffee table and handed them over.

At the same time, he slowly recounted the day one year ago and picked up the murder that happened at home.

From 7 to 12 o'clock that night, everyone except Okudaira was watching home videos in the living room.

Although Okudaira Takugo's behavior of not returning home all night made people feel uneasy, but when he thought that the other party was an adult, Okudaira Kakuzo, as the head of the family, just complained a few times and did not pursue anything further.

As a result, the next morning.

When the maid was cleaning the yard, she discovered that Okhira Takugo had drowned in the swimming pool.

After the police arrived, they inspected the death scene and confirmed that the time of death was between 9 and 10 p.m.

At that time, everyone living in the villa had alibi.

"Then this photo was taken by the police during the investigation of the scene?" Mouri Kogoro stared at the photo for a while, frowning and said: "It seems to be a bit moldy..."

He was not wearing shoes or socks, and was wearing a glove on his right hand. His hands and feet were tied behind his back, and his mouth was taped with tape.

Judging from the photos alone, it is a very simple and clear case of murder...

Ye Gengyi made an analysis and said: "The pixels are very low. It is not police equipment. It may be a screenshot of a video."

"Screenshot of the video?" Moori Kogoro wondered, "Is it true?"

"He's right."

"This is indeed an excerpt from the videotape taken when my son's body was found," Okuhira Kakuzo said.

"Strange? It's not a photo but a video."

Mouri Kogoro said doubtfully: "As far as I know, the case has not been solved yet. It is unlikely that the police will provide you with this."

"No, it was taken after the water in the swimming pool was drained the next morning because the maid was yelling and found Touto's body..."

Okuhira Kakuzo looked annoyed, "When I recorded the video, I thought he was joking, but it turned out to be true."

"Uh, so that's it..."

Mouri Kogoro put the photo on the table and continued to ask: "Does your son have any enemies?"

"As far as I know, there isn't one out there, but..."

Okuhira Kakuzo said slowly and heavily: "There are some at home."

At home?

It should be just suspicion, otherwise with the attitude shown by the other party, it would be impossible to tolerate nearly a year.

But his tone was so determined... Could it be that he had some information that was inconvenient to tell the police?

Ye Geng glanced at a certain tool man.

wrong……

If there was any information that could not be known to the police, he also had no reason to agree to hire the famous detective Mouri Kogoro to track down the real culprit who killed Okhira Deugo after my persuasion.

There is really a strange sense of dissonance...

What did I overlook?

Ye Gengyi's eyes fell on the books in the room again.

Huh? Wait a minute... Is it possible that this family doesn't pay much attention to the news? So I don't know much about the relationship between Mouri Kogoro and the police. I think that no matter whether the detective has a name or not, at best, he is the employer and the employee.

Relationship.

Let’s think about Okuhira Kakuzo’s attitude toward his butler Segawa Hatakero who comes and goes whenever he calls...

It seems that the strategy of not directly using his identity as the police to investigate, but compromisingly coming with the detective, was really a good one.

Just when he was thinking.

On the other side, Mouri Kogoro was also surprised and confused by the clues provided by Okudaira Kakuzo:

"But, didn't you just say that before and after the hair loss, all of you were watching videos in the living room?"

He held his chin with one hand and pondered for a moment, then suddenly said:

"Could it be that there is a secret door in the living room, and the murderer took the opportunity to escape into the yard and kill people?"

"No, there is no such mechanism installed in the villa."

Okudaira Kakuzo shook his head, "Although someone went to the bathroom on the way, the bathroom is right next to the living room, and there is only one window for ventilation. Even with my size, I can't climb out from there."

"Well……"

Before Mouri Kogoro had time to raise any other doubts, he was silenced by the other party's denials one after another.

He was silent for a moment and then said helplessly: "Well, Mr. Oppei, since no one could go to the yard at the time of the incident, why do you believe that the murderer must be someone in the family?"

"Because someone put a glove on Duowu's right hand!"

Okuhira Kakuzo pointed to the photo and said: "Those are the gloves of the former housekeeper who fell off a cliff and died in a car accident two years ago today!"

"Today two years ago?" Mouri Kogoro frowned, "It happened to be the same day one year apart from your son?"

"That's right, on the third day after my son's death, the glove on his left hand appeared in my study." Okuhira Kakuzo's expression became increasingly gloomy.

Serial murder?

If such a guy lived in the villa, let alone a normal person, even a tough-minded person might not be able to endure it.

Therefore, this is not the reason for him to endure and hesitate for a year, at least... there is something hidden behind it.

However, it is obviously impossible for Mouri Kogoro to notice this detail...

Ye Gengyi was about to ask questions on behalf of the tool man when he suddenly heard footsteps approaching the study door.

After just a slight pause, Mouri Kogoro overcame him:

"Oh, I understand... you mean that the murderer kidnapped the young master in this study at first, and after putting on gloves for him, for some reason, he accidentally dropped one of them here!"

"ha?!"

Oban Kakuzo looked confused at first, then became impatient and blurted out: "I mean, someone has a grudge against the death of the former butler."

Um?

Holding a grudge? It turns out that the car accident was not an accident... Ye Geng suddenly understood and glanced at a certain tool man calmly.

Very good. This kind of almost coincidental evidence clue, even if I try to get a confession, it may not be so smooth.

Hmm... To sum up, this method can be called: pretending to be stupid and shameful, but very useful?
To be continued...
