In the study room of Dacun Villa.
When Agasa Yuyuki and the others came to the study.
I saw the middle-aged man, Isao Tatsumura, who fell to the ground and died of poisoning!
Looking at Isao Tatsumura who fell to the ground, dead.
The expression on Mrs. Damura's face instantly became panicked.
Conan and Agasa ignored Mrs. Tatsumura's panic.
The two of them ran directly to where Isao Tatsumura fell to the ground.
You might find something interesting.
First of all, Agasa discovered that Isao Tatsumura's body was still warm.
It means that his death time was within an hour.
His lips were purple and he seemed to have died of poisoning.
And from the neck, I saw red spots that seemed to have been pricked by needle tips.
It seems that the murderer used a poisonous needle to stab the deceased in the neck.
To achieve the purpose of poisoning and death.
Hiroyuki Agasa was squatting on the ground, thinking about the time of death of the other party.
Conan looked under the desk.
There is a strange thing.
So he hurriedly ran to the place under the desk.
When Conan was hiding under the desk, he happened to see a strange sharp needle.
After he saw strange white pointed needles.
He hurriedly called Agasa Hiroyuki who was checking Tatsumura Isao's body.
"Brother A Li, I saw something very interesting."
Yuuki Agasa, who was squatting on the ground, was thinking about the cause of death of the deceased.
Hattori Heiji's head just hit Conan.
Hattori Heiji saw Conan squatting next to him.
An angry expression immediately appeared on his face. And scolded him: "Why are you here?"
After saying that, he planned to pick up the silver needle on the ground.
Let's see if this thing is the murder weapon that killed Isao Tatsumura.
Hiroyuki Agasa, who was about to come to Conan, saw Hattori Heiji picking up a silver needle with his bare hands.
He hurriedly stopped him and said, "Wait a minute, Hattori Heiji. You can't touch anything suspicious at the scene with your bare hands."
Then, Agasa stepped out directly from the blue sportswear.
Pull out a clean piece of toilet paper.
Then he carefully wrapped the back end of the silver needle with toilet paper.
Then put it on the table.
After Agasa Yuyuki did all this.
Officer Megure also came to the scene.
After Officer Megure arrived at the scene.
He, Hiroyuki Agasa, and Kogoro Mouri.
I figured out what happened.
After listening to the explanation, Officer Megure said to Kogoro Mouri: "Well, I roughly understand the matter. The victim Isao Tatsumura was 54 years old. The cause of death may be that he was stabbed in the neck with a poisonous silver needle."
Then, Officer Megure looked at Mouri Kogoro and Conan with mocking eyes.
Mouri Kogoro noticed that Officer Megure looked at him with a mocking look.
He asked with an awkward smile on his face: "Officer Memu, why are you looking at me strangely?"
Officer Megure sighed helplessly and replied to him: "Wherever you appear, unfortunate things will happen. So do you think I will have a good look on you?"
Mouri Kogoro, who was complained about, could only smile with a smile on his face.
In response to Officer Megure's complaint about himself.
But soon, Officer Megure asked Mori Kogoro seriously: "Since the cause of death of the deceased was poisoning. And we also saw the murder weapon and poisonous needle at the crime scene. So the question is, how did the murderer start? Yes, and who would be suspected of killing Isao Tatsumura?"
Officer Megure asked this.
Hattori Heiji said to Officer Megure: "Based on the current physical condition of the deceased, the deceased must have been stabbed to death by the murderer with a silver needle when we first entered the study, or within an hour of his death. So if you stay here Everyone in the villa will be suspect. Except Mrs. Damura who entered the study with us."
Mrs. Tatsumura, who was standing in the study room, heard what Hattori Heiji said.
An inexplicable smile appeared at the corner of his mouth.
But in order to cover up her strange expression, the expression on her face still pretended to be sad.
After hearing what Hattori Heiji said, Officer Megure asked Mouri Kogoro: "Who is that dark-skinned young man?"
Mouri Kogoro answered casually to Officer Megure: "His name is Hattori Heiji, and he calls himself a famous detective in Kansai."
After Officer Megure heard Kogoro Mouri's answer.
An expression of surprise suddenly appeared on his face.
Because Hattori Heiji's father is a senior official at the Osaka Police Department.
Xiaolan looked at Hattori Heiji's back, looking more and more like Kudo Shinichi.
Xiaolan wondered why this guy looked so much like Kudo Shinichi.
Conan sneezed uncontrollably again.
After seeing it, Agasa Hiroyuki immediately asked Conan: "Are you okay now?"
Conan replied to Agasa Hiroyuki: "I feel like my cold is getting a little more serious, and I blame that guy Hattori Heiji. He knew I had a cold, but he even let me drink white wine."
After Xiaolan heard Conan's words, she looked at Hattori Heiji with an even more unhappy expression.
Hattori Heiji noticed that Ran looked at him with hostile eyes.
He hurriedly lowered his head to avoid Xiaolan's gaze directed at him.
Officer Megure looked at the window that was covered by curtains and obviously locked.
He asked Mrs. Tatsumura in the study: "Mrs. Tatsumura, I have a question for you. How many keys to the study of the deceased Mr. Tatsumura do you have?"
Mrs. Damura immediately replied: "I have one key and my husband has one. I think the other key should be in my husband's pocket."
After Officer Megure heard this, he immediately walked over to the deceased.
The keys were found in the pocket of the deceased's trousers.
This made Conan and Hattori Heiji have stunned expressions on their faces.
And Agasa was thinking about why the deceased's blue trousers had two pockets, an inner one and an inner one.
The first layer is an outer pocket, and the second layer is a small pocket that can only hold keys.
Mouri Kogoro looked at Conan's surprised expression and asked Hattori Heiji: "Is there anything wrong with this?"
Hattori Heiji looked at Mouri Kogoro and asked such a stupid question.
She explained to him speechlessly: "Can't you see something? Before we came to the study, the door of the study was locked. The key found in the deceased's pocket showed that it was the key that the murderer used after killing the deceased. . Use special techniques to put the key back on the deceased."
After hearing this, Mouri Kogoro asked Hattori Heiji: "So, this is a secret room murder case. And when we entered the study, we happened to see the sound of music playing. Can it cover up the fact that the deceased was murdered?"
After hearing this, Hattori Heiji nodded in approval.
Agasa Hiroyuki thinks that if you follow what Hattori Heiji said.
Then the body temperature of the deceased should have dissipated long ago.
And if we really want to do a secret room murder, does it need to be so troublesome?
So conversely, it is precisely because the body of the deceased is still warm.
It shows that there is a chance that there is only one person who killed Mr. Isao Tatsumura.
That is Mrs. Damura.
But how did she easily kill Isao Tatsumura who was in a comatose state under everyone's noses.
Could it be that Isao Tatsumura was already in a comatose state when he entered the room.
And when he, Conan and the others entered the study.
Is the position where Isao Tatsumura's arms were hanging on the desk deliberately manipulated by the murderer?
When A Li was thinking about the possibility of Mrs. Tatsumura committing a crime.
Hattori Heiji became more and more convinced that the Mouri Kogoro in front of him was simply a parallel import.
Newspapers say that Mouri Kogoro is obsessed with handling cases, but in fact it is bullshit.
When Hattori Heiji looked at Mouri Kogoro with a mocking look.
Conan is also thinking about how to solve the case quickly...
