Dr. Asasa at home.

Ai Ashbara discusses with Conan about how to find Professor Hirota.

Dr. Asa hears Ashara's words.

He said that he knew this Professor Hirota.

Dr. Asa immediately called Professor Hirota.

Soon, Professor Hirota's older voice came from the other end of the phone.

"Hey, you're Dr. Asasa. What are you looking for me? ”

Dr. Asasa immediately told Professor Hirota on the other end of the phone what he had requested.

"That's right, Dr. Asasa. Indeed, Akemi Miyano is indeed, it seems that she has put something in my house. If you have time, come and pick it up tonight. ”

When Dr. Asa heard this, he immediately said that we should come over.

Then Dr. Asa turned pale and excitedly said to Conan, "Alright, now let's go." ”

With that, he took Gray Yuan to mourn them and went to Professor Hirota's house.

After they arrived, Professor Hirota's doorstep.

A middle-aged woman in a red sweater receives Dr. Asasa.

Dr. Asasa made his request clear.

The woman smiled and said to Dr. Asasa, "Oh, you're Dr. Asasa." My husband is in the study at home. Come with me. ”

Soon, the middle-aged woman took Dr. Asa and them to the door of Professor Hirota's study.

When they came to the door of the study.

Dr. Asa stretched out his left hand and knocked on the door of the study.

But after waiting for three minutes, I didn't hear the response in the study.

And the door of the study seems to be in a state of anti-locking.

Conan, who was standing at the door, found that this was not normal.

Then he said to Yuyuki Agasa beside him: "Brother Agasa, you lift my body up, and I'll see what happens." ”

When Yuyuki Agasa heard Conan's request, he immediately lifted Conan's body.

When Conan was lifted up, he saw the window glass on the top of the study.

Professor Hirota's body was pressed against a red wooden bookcase.

On his forehead, there are obvious marks of being knocked out.

Conan saw what was happening in the study.

Conan immediately turned to the middle-aged woman and asked, "Auntie, something happened to Uncle Hirota." Do you have a spare key to the study. ”

The middle-aged woman heard Conan's serious tone, and she replied helplessly, "I don't have a spare key to the house." ”

Hearing this, Conan could only say to Dr. Asa and Yuyuki Agasa, "There is only one way now, and that is to slam the door open." ”

Dr. Asasa and Yuyuki Asasa glanced at each other.

He nodded his head and said he banged on the door together.

As the two of them slammed their bodies hard against the door.

The study that was locked was quickly knocked open.

At the same time as banging on the door.

Conan also called the police and waited for the police to arrive.

Thirty minutes later, the police arrived at Professor Hirota's study.

At this point, a slender police officer in a brown suit resembling an explosive head.

He took the initiative to introduce Dr. Asasa to Dr. Asasa, "Hello, I'm Officer Yokogou. Is it the case you reported? ”

Dr. Asasa nodded in agreement.

Subsequently, the Henggou police officer observed the arrangement of the environment around the deceased.

He said to Dr. Asasa: "Looking at the current condition of the deceased, the cause of death may be because the deceased accidentally let the bookcase fall on him. At the same time, a trophy placed on top of the bookcase smashed into his head. Then let him bleed to death. Because I think it should be an accident. ”

After hearing Officer Yokomizo's introduction, Agasa asked dissatisfiedly: "If it is really that simple, then how can the key to his study be pressed under a book." ”

When Officer Henggou heard this, he pointed to the books scattered on the ground.

replied with a dissatisfied expression: "Since it was all an accident, then you still need to care about this detail." And the moment his body fell, maybe the key he had in his pocket slipped straight out. ”

Conan after hearing Officer Yokomizo's explanation.

A mocking smile appeared on his face.

Immediately, he gave a different opinion to Officer Henggou.

"Oh no, how did his landline phone fall to the ground. And why put a book on the phone? I think this is a case of murder in a closed room! ”

Officer Yokogou after hearing Conan's opinion.

Just wanted to show if you're talking nonsense.

Later, when he saw Conan's trademark blue suit and the round-rimmed glasses he was wearing.

The expression on his face immediately became surprised.

He then asked Dr. Asasa, "He's Conan, the little imp next to Kogoro Maori." ”

Dr. Asa immediately nodded in agreement.

When Officer Henggou heard this, he immediately asked the middle-aged woman beside him, "If it is a case of murder in a closed room, then may I ask Mrs. Hirota, who came to Dr. Hirota's study tonight." ”

When Mrs. Hirota heard Officer Yokomizo's words, she hurriedly provided Officer Yokomizo with information about all the people who had visited tonight.

At the same time, in order to prevent the police officer from misunderstanding, he is also suspected of murder.

She hurriedly testified that she and her wife went shopping at a nearby supermarket at the time of the crime.

When Officer Henggou heard this, he planned to immediately call all the guests who came tonight.

Maybe there's something surprising.

At the officer of the Yokomizo, talk to Mrs. Hirota, who has made an appointment in advance tonight, when coming here.

Sitting at the computer desk, Gray Yuan Wai is controlling something on the computer.

Then I saw Gray Yuan Wai say to Yuyuki Agasa beside him: "The magnetic data in the computer has been completely emptied. ”

When Yuyuki Agasa heard this, he said to Gray Yuan, "This doesn't mean that we came for nothing. ”

When Yuyuki Asasa wanted to say something.

Officer Henggou saw it, as if in the troublesome gray plain mourning after them.

With an ugly expression, he said, don't affect our case.

After Agasa was fortunate enough to see Officer Yokomizo's ugly expression.

He pulled the gray plain mourning and came to the door of the study.

At the door of the study.

Conan looked at the forensic officer who was in the study, who was taking pictures of the crime scene, and Officer Yokozo, who was talking to Mrs. Hirota.

He asked Gray Plains, "Do you think he will die at the hands of the Order?" ”

Gray Yuan Ai lowered his head and thought for a while and replied, "It's indeed possible, but they won't go to great lengths to make a so-called secret room murder crime scene. So I can't guarantee that he might die at the hands of the Order. ”

Conan knew what Gray Hara had said.

Then he said to Gray Yuan: "Then I'll take a look and talk about the suspects who visited today." ”

After Conan finished speaking to Gray Plains.

Once again, he returned to the study where the crime occurred.

It's just that this time he found that the landline phone was actually in the state of calling and leaving a message.

This confuses Conan. Why is the phone in the call message status.

It's not a busy beep.

So he hurriedly called Officer Yokomizo, who was talking to Mrs. Hirota.

When Officer Yokogou heard Conan's words, he immediately walked to Conan's side.

And the thing that surprised Officer Yokozo was.

The message storage device of this landline phone is actually in the form of a cassette tape.

In today's era of advanced technology, there is no one who still uses ancient tapes to store them.

That's not what they're focused on, though.

So he asked Conan to turn on the call and message function, maybe in the message.

What valuable clues can be found...
