In the living room of Masao's house.
Officer Shiratori was giving orders, the policeman standing at the door.
After expanding the search scope.
With an impatient expression, he said to Agasa Yuyuki and the others: "Why don't you leave yet?"
Agasa Hiroyuki asked Officer Shiratori: "Officer Shiratori, why do you insist that it was someone else who killed Miss Kayoko? It was not Masao Ichiro who used certain methods to kill the deceased Masao Kayoko."
Masuo Ichiro, who was standing aside, heard what Agasa Yuyuki said.
He immediately retorted: "You have to know, I was in the police station when the crime happened. I don't have the teleportation function. I returned to the police station at the moment when I killed my wife."
After Masao Ichiro finished expressing his alibi.
Officer Sato opened another bookcase that was slightly shorter than the bookcase next to the wall.
He said to Officer Shiratori: "It's strange, why is this bookcase full of books, but this tall bookcase has three empty floors. This is very unreasonable."
After Officer Sato finished speaking his opinion.
He hurried over to a policeman who was searching the deceased's room.
And he took a photo album and handed it to Officer Shiratori.
After taking the photo album, Officer Shiratori asked him: "Is there anything wrong with this photo album?"
The policeman holding the photo album opened it.
After pointing to a few photos in the album.
He said in a confused tone: "I really don't understand why he focused on a certain person in a few photos in the album."
After Masao Ichiro saw the photo album, he hurriedly said: "This is my wife's prank."
Then he snatched the photo album from the policeman's hand.
Conan looked at him with a rare nervous expression.
Then he asked Agasa: "What do you think is the probability that he is the murderer?"
After hearing Conan's question, Agasa carefully replied to him: "I think he is very suspicious. And I have already said that this is a secret room murder case. But what we are missing now is how to learn about him. Modus operandi.”
After he finished speaking, he had a confused look on his face.
Stare at the bicycle exercise equipment in front of you.
Just as Agasa Yuyuki was staring at the bicycle exercise equipment.
Masuo Ichiro suddenly made a strange movement and subconsciously licked the fingers of his right hand.
Hiroyuki Agasa also saw his strange behavior, so he asked Conan: "His behavior is very suspicious."
Conan nodded to express his approval of Agasa.
At the same time, he asked Agasa: "Do you think there is anything wrong with this bicycle fitness equipment?"
When A Li walked to the bicycle fitness equipment, he was about to find a few interesting things.
Officer Shiratori still insists that this case is a burglary and homicide case.
However, just after Officer Shiratori said that it was impossible for the dagger to fly to the victim's back by itself.
Conan immediately said excitedly to Arisaki: "I know, your reasoning is correct. I believe this bicycle is a fitness equipment. You can definitely find some interesting things."
Sure enough, Hiroyuki Agasa and Conan were right next to the axle of the bicycle fitness equipment.
Found a kite string that had been wound several times.
After seeing the kite string, Agasa couldn't help but said in surprise to Conan: "Could it be that the deceased stepped on the pedals of the bicycle, and then let the kite string continue to wrap around the axle. Finally, the kite string was stepped on by the deceased. After reaching the end, the dagger flew out from the bookcase behind her and stabbed Kayoko directly to death."
After Conan heard Agasa Yuyuki's words, he nodded to express his approval.
At the same time, he motioned to Agasa to see if he could find anything interesting on the bookcase.
As a result, A Li found traces of several thumbtacks on the top of the bookcase.
Moreover, there were some strange blood stains on the bookcase and the curtain.
So he told Conan what he had discovered.
Officer Shiratori saw Agasa Yuyuki’s strange look.
While staring at the bookcase in front of me.
Then he asked Officer Shiratori with a confused expression: "Don't you think there is something wrong with this bookcase?"
Officer Shiratori walked behind the bookcase with blood stains.
He couldn't help but asked with confusion: "What's wrong with this bookcase?"
When Officer Shiratori asked what was strange about this bookcase.
Masuo Ichiro in the room had a panic expression on his face.
Conan saw the panic expression on his face, and an excited smile suddenly appeared on his lips.
Then I made a paper knife.
At the same time, Hiroyuki Agasa said to Officer Shiratori: "Now, it's up to Conan and I to unravel the so-called secret room murder modus operandi for you."
Officer Sato looked at Hiroyuki Agasa and Conan, singing in harmony.
He suddenly said with a puzzled expression: "What are you doing?"
Conan then asked Officer Sato: "Have you noticed that the knife stabbed the deceased's back horizontally. And if someone killed him in a sneak attack, it should have stabbed the deceased's back vertically."
Officer Shiratori and Officer Sato were shocked when they heard Conan's words.
Officer Takagi also echoed: "What Conan said makes sense. And it also fits the requirements of secret room murder."
Officer Shiratori felt that it was the murderer who pressed the deceased to the ground.
The deceased is then killed.
After hearing his reasoning, Agasa couldn't help but retort: "If what you said makes sense, then there should be a lot of sweat stains from her on the floor. And don't you think it's weird where the deceased's phone fell? .”
Officer Sato also immediately thought of something.
Said to Officer Shiratori: "If I were the murderer, I would hang up the phone directly after killing Ms. Kayoko, instead of being on the phone all the time, but there would be no noise such as footsteps."
Even though Shiratori heard what Officer Sato said, he couldn't help but smile awkwardly.
Agasa Hiroyuki also reasoned to Officer Shiratori: "The glass with a strange circular gap is very strange. And when he entered the house, his door and windows were locked. . This does not prove my initial judgment that he is a secret room murder case!"
After Officer Sato heard what Agasa Yuyuki said.
He couldn't help but agree: "In this case, we need to check again."
Officer Shiratori looked at Agasa Yuki's confident look.
He directly questioned Arisuki: "If what you said is right, then give me the evidence."
Agasa Hiroyuki pointed to the wheel axle of the bicycle.
Signaling Officer Shiratori to take a closer look.
As a result, after Officer Shiratori discovered the kite string, he asked Masao Ichiro: "Can you explain this kite string?"
Don't wait for Masao Ichiro to explain the kite string.
Agasa took out the strange coil on the other end of the kite string.
Then he asked Masao Ichiro: "Excuse me, can you explain this thing?"
Masao Ichiro hurriedly explained: "Maybe it was the prank that the children came to my house a few days ago."
After hearing this, Agasa immediately retorted: "Really? If we fix the dagger with tape on the top of the highest bookcase. Then stick a thumbtack on the top of the bookcase. Then put a thumbtack on the thumbtack. Kite coil. The other end is tied to the axle of the bicycle fitness equipment. As long as the deceased keeps pedaling the bicycle, then the dagger placed on the top of the cabinet will? "
After Officer Shiratori heard this, he immediately retorted: "The theory is correct, but the question is, when the deceased was riding on the bicycle fitness equipment, couldn't she feel the resistance brought by the kite string? You need to know that The quality of the cabinet is quite heavy, how could it be easily pulled down by a kite string?"
After hearing this, Officer Sato explained with a smile: "Don't you know that this kind of bicycle fitness equipment can adjust the pedal strength? As long as the adjustment is in place, he will not feel the so-called resistance."
After Officer Shiratori heard this, he still thought it was impossible.
After Officer Takagi heard this, he immediately said to Officer Shiratori: "I finally understand the reason why you keep looking at your watch in the Metropolitan Police Department."
Officer Sato also thought of something.
Then he asked Masuo Ichiro: "I suddenly remembered something, why did you ask us to go to the second floor first after entering the room. If I am right, there should be something on the cabinet higher against the wall. There are a lot of books. As a result, due to time constraints, you only have time to put the books in the lower cabinets, and then put the high cabinets against the wall, so there will naturally be three levels of space."
After Ichiro Masuo heard this, he quickly retorted: "Even if you are right, I don't have enough time. One more thing is that the dagger fixed on the cabinet should still be on the cabinet."
After hearing this, Agasa sneered at him and said, "Yes, that's right, but the cabinet shelf on that cabinet can be raised. If we fill the second and third floors with books, What if the dagger is fixed on the first floor?"
After Masao Ichiro saw Conan, he almost restored his own modus operandi.
He finally retorted to him: "Can't he see the dagger on the top of the cabinet?"
Finally, Agasa Hiroyuki retorted to Masao Ichiro: "What if I put a few books on the top of the cabinet. Also, why are there strange blood stains on the top of the cabinet."
Conan also took out his right hand and asked about his injured index finger: "What's wrong with your index finger? Is there a thumbtack in the pocket that fixes the end of the kite string?"
As Conan spoke out, the evidence was the last straw that broke the camel's back.
Masao Ichiro could only honestly tell everyone the reason for his crime.
After Officer Sato listened to Masao Ichiro's words, she suddenly remembered something.
So he said with a wicked smile: "I finally understand the secret of the circle on the photo in the album. Because the circled person is your accomplice. And you are the only one who can understand the internal structure of the bank, so you Is there anything else you want to say?”
After being exposed, Masuo Ichiro could only honestly confess the whereabouts of his accomplices.
As the police caught the remaining gangsters.
This so-called 100 million yen robbery was successfully solved.
Officer Shiratori, standing at the gate of the Metropolitan Police Department, looked at the beautiful sunset on the horizon.
He couldn't help but said to Officer Sato: "Officer Sato, can I treat you to French cuisine tonight?"
Officer Sato glanced at Officer Takagi with a nervous expression.
He expressed his refusal in a tactful tone.
Officer Shiratori saw her obvious refusal.
He could only lower his head in despair, turn around and leave in the distance.
Officer Sato looked at Officer Shiratori’s leaving figure.
Then he motioned to go to a nearby snack bar and eat Oden together.
After Officer Takagi heard this, an excited smile suddenly appeared on his face.
However, before Officer Takagi could prepare, he planned to plan a happy night.
Officer Megure suddenly came out of the Metropolitan Police Department and invited everyone to have a feast together.
After Officer Sato heard this, he immediately nodded in agreement.
Although Officer Sato wanted to invite Officer Takagi to go with him.
But Officer Takagi, who was thinking too much, could only express very speechlessly that he had to continue working in the afternoon.
At eight o'clock in the evening, in the office hall of the Metropolitan Police Department.
Arisuki, who had been waiting for a long time, calmly said to Officer Takagi who was lying on the table in a depressed state: "Things are not as bad as you think. And Officer Megure is already married, could he cheat on his wife?" ."
After hearing Hiroyuki Agasa's persuasion, Officer Takagi immediately returned to his normal expression.
The so-called work of recording confessions began...
