Sunday, April 4th, morning, Hachioji City, Tama New Town District, Katsura Masuo.

Katsura Masuo's house is a three-story one-family building, and after opening the door and leading Officer Sato and Officer Takagi into the room, he pointed to the stairs and said, "Officer, please go upstairs and have a look, and I'll go to the hall to look for it." He ran down the hall.

"Okay," Officer Sato said, "let's go, Takagi." As he spoke, he ran upstairs, and Takagi immediately followed.

Conan also walked into the room, and when he was about to keep up with Katsura Massuo, he suddenly felt the wind, and looked in the direction, and found a round hole in the window glass, and when he looked closely, it happened to be on the lock edge of the window, was it an external offense?

At this time, there was a scream from Katsuzo Masuo in the hall, and Officer Takagi, Officer Sato, and Conan ran to the scene together, and found Katsura Masuo sitting on the ground in front of the door, pointing forward with a trembling finger, and looking in the direction he pointed, a woman was lying motionless on the ground on the right side of a bicycle-style exercise machine, with a knife stuck in her back, and her back coat had been dyed red.

There is not much furniture in this room, except for the Japanese-style table in the middle of the room and the cabinet next to the table, only on the left side of the door, there are one small and one large bookshelves from the wall, and less than a meter away in front of the large bookshelf is a bicycle-type sports machine, and on the left side of the sports machine is a long platform.

Officer Sato immediately ran forward to check, and Officer Takagi went to call an ambulance.

"No," Officer Sato said, "it's the photographer who should be called." ”

"Photographer, photographer!" Officer Takagi and the three of them were taken aback.

Officer Sato glanced down the hall and said into the floor-to-ceiling curtains, "Come out, people behind the curtains." ”

"Slap ......" With applause, Oda Nobue, Oda Sakurako and Oda Haruko came out, and Oda Haruko was still holding a portable video recorder.

"Officer Sato, what a wonderful show. Oda Nobue smiled.

"Miss Nobue, why are you here?" Officer Sato asked.

"We took the order to investigate Friday's bank robbery. Haruko Oda said, "You police are really not trustworthy, and in front of everyone's eyes, you let two gunmen run away with the money, and you haven't caught them yet." ”

Seeing that Officer Sato's face changed, Oda Sakurako hurriedly stopped: "Haruko!"

"I'm telling the truth. Haruko Oda said.

Taking a breath to suppress his anger, Officer Sato asked, "I'm asking about things here, what's going on with this dummy?"

"Dummy!" Officer Takagi and the three of them were taken aback, and Katsura Masao's face turned white.

"It's a trap set by some guy, and the prey didn't catch it, but he accidentally fell into it. Oda Nobue looked at Katsura Masuo and smiled.

"What are you talking about," cried Katsura Massuo, "why are you in my house, my wife?"

"Don't you understand? We were hired by the consortium behind your bank to investigate you. Haruko Oda said.

"Suzu, Suzuki Foundation!" Katsura Massuo's sweat came down.

"As for your wife, she is now being treated at Hachioji City Hospital. Oda Sakurako said.

"What the hell is going on?" Officer Sato said to get the portable video recorder in Haruko Oda's hand, "Let me see what you guys are shooting." ”

Sakurako Oda stood in front of Officer Sato, "I'm sorry, Officer Sato, I can't show you. ”

"So, while you have time, let's reason and see how about it, Officer Sato, Officer Takagi?" Nobue Oda laughed, "Just like Mrs. Masuo is falling on the ground." ”

"Reasoning?" Officer Sato said, "Okay. ”

"Well, don't mind if I'm on board. "The White Bird Police Department has come in.

"Of course I don't mind, Shiratori Police Department supplement, no, it's the police department," Oda Nobue smiled, "I heard that you have been promoted to the police department, congratulations." ”

"You're welcome. The Shiratori Police Department smiled a little smugly.

"Sakurako, that one in Kyoto is already a police department. Haruko Oda asked with a smile.

"Ahem, ahem!" the Shiratori police department choked on saliva.

At this time, Mori came in with Hattori and Yamazaki, looked at the situation in the house, and asked, "Who is this who is dead?"

Glancing at the camera, Yamazaki took a few steps to the side.

"It should be Mrs. Masacchi. Shiratori said.

"It's a dummy, Shiratori Police Department. Officer Takagi reminded.

"Dummy?" the Shiratori Police Department and the three Maori were surprised.

Officer Takagi talks about it for a moment, and then he talks about the reasoning game.

Oda Sakurako smiled: "Officers, I would like to remind you that it is best for you to participate, especially Officer Sato and Officer Takagi. ”

"Reasoning games?" Maori said angrily, "Then I'll go first." ”

"There will be a bonus, Mr. Maori. Haruko Oda laughed.

"Ahem!" Maori immediately changed his words, "this game sounds interesting, I'll join in." Then he asked, "Well, Miss Haruko, how much money will there be?"

"It depends on how much lost money can be recovered in the end. Sakurako Oda said with a smile, "The Suzuki Foundation will use it as a percentage. ”

"Hundred, percent!" Maori drooled, then quickly sucked it back, and continued, "Then let's get started." First of all, it's the three of you who have been wandering around Mr. Masao's house lately. ”

"Wrong, Mr. Maori, how could we be discovered. Haruko Oda laughed.

Oda Sakurako smiled, "We lived in three families next door to him, and we paid a lot of rent." ”

"That's right. Maori said embarrassedly.

"The victim was Mrs. Zengwei, and the murder weapon was the knife behind her back, which happened to be the back of the heart, and she was killed with a knife. Officer Sato said, "I think the time of the murder was probably when Mrs. Masuo screamed, which means that Mrs. Masuo was attacked from behind by someone while talking on the phone." ”

"It should be when she is talking on the phone while using this sports machine, there is no telephone landline here, she must be afraid of a sudden call during exercise, so she took the phone extension. The Shiratori Police Department stepped forward to look at the sports machine, "The recording switch on the sports machine has been turned on. He continued, "Mrs. Masuo called Takagi today and said that she would go to the Metropolitan Police Department to tell her about the bank robbery, and she told Takagi on the phone, 'It's the police officer from before,' so this is a purposeful murder against Mrs. Masao, in order to prevent her from telling the police about the bank robbery, that is, the murderer should be a bank robber." ”

Officer Sato said: "Mrs. Masuo once caught a prisoner's mask during the bank robbery incident, although it is not clear in the video whether Mrs. Masuo saw the face of the prisoner, but maybe she knew some features, such as the mole on the side of the mouth, so the prisoner thought that she had seen through it, so she came to kill people." ”

"Didn't the prisoner kill her at the time?" asked Maori.

Because Mrs. Mui, who happened to be present, Mrs. Muwi saw that Mrs. Masuo was resisting fiercely, and she was afraid that the gangsters would attack her, so she took the initiative to go up and replace her. "The gangsters may have been afraid of killing the hostages, and the nature of the incident changed, so they didn't do it, but did it afterwards." ”

"But, isn't that very strange?" Officer Takagi asked, "Since it was for Mrs. Masao, when did the gangsters come? If they came before the phone call, then they should have done it before, and if so, how do you know that she was talking to the police on the phone?"

"Quite simply, the murderer went to the other rooms to make sure that Madame Masuo was the only one in the room, and then he came back to attack Masuo," Maori said, "and at that time, Madame Masuo happened to be on the phone, and as for the conversation, I think if the hall was open, it could be heard in other rooms nearby." Then he said to Oda Nobue, "Is that so?" Mrs. Masuo was riding her bicycle and making a phone call, when the murderer came in and slipped behind her and killed her. ”

"Good guess," Oda Nobue laughed, "but in fact, please look at the big bookshelf behind the sports machine." ”

"Bookshelves?" Shiratori opened the curtain of the bookshelf and found that it was empty, only a few bays, and then found that there were red, blood-like marks on the top frame, so he asked uncertainly, "This is?"

Oda Nobue said, "There is no doubt that it was really Madame Massuo's blood, and it was definitely not smeared by us. ”

"Please let me see. Hattori stepped forward to take a look, then pulled open the small bookshelf next to it and found that it was full of books.

"Hold me and look at it. Conan said to Hattori.

"Okay. Hattori picked up Conan, showed him the top of the large bookshelf, and asked, "How's it going, is there that thing?"

Looking at the bloodstained piece of tape and a few thumbtacks on it, Conan laughed, "Yes, it's here." ”

"What are you doing?" asked Maori, "what's up there?"

"I've always wondered if Mr. Masuo should have seen this dummy as soon as he came in, no, this body. Hattori laughed, "But why didn't he say anything? because he was going to change the scene." Then he opened the cabinet under the long table, revealing a mess of books.

"Could it be that these books were originally on the shelves?" the Shiratori Police Department picked up a book and found some blood stains on it, "I see, if I'm not mistaken, this bookshelf turned out to have fallen to the ground and pressed against the body of this dummy, no, body." The books didn't have time to fit on the shelves, so they were stuffed into cabinets. ”

Maori said: "In other words, Mr. Masao, you helped it up, so the murderer is you." ”

"Ahem, Mr. Maori, it is possible that the murderer will pick up this bookshelf and walk away again, in order to confuse the police. Haruko Oda laughed, "And Mr. Masuo was just scared." ”

"Alright, Haruko. Sakurako Oda stopped.

Officer Sato asked, "Miss Nobue, stop going around in circles, what's going on?"

"I'm sorry," Oda Nobue said, "This reasoning game can be played by others, but you and Officer Takagi must continue to play it, for a reason, when you go back, Administrator Matsumoto will tell you." ”

"Officer Matsumoto!" Officer Sato and Officer Takagi were taken aback.

"Alright, both, please continue reasoning. Oda Nobue said. "Again, please treat this as if it were a real scene. ”

Seeing that Officer Sato and Officer Takagi didn't have a breakthrough for a while, Conan reminded, "Now, why is this knife horizontal?"

"Needless to say, there are bones in the back, and this kind of knife can only be pierced by a horizontal knife in this part, and it can kill people. Shiratori said.

"Wait," Officer Takagi said, "if the knife is horizontal, if the bookshelf is on the body, is that okay?" As he spoke, he placed the books in the cabinet on the top layer of the shelf, then took a few thin ones and replaced them with a few thick ones, so that the books in the bookshelf were stretched, and then pulled out the knife from the dummy and stuffed it into the gap between the top of the book and the frame of the shelf.

"Are you kidding? How do you kill people like that? Wait," said Shiratori Police, touching his chin, "if the bookshelf falls down and sticks it on someone, maybe it can really kill someone." Then he asked, "How do you get the bookshelves to fall down?"

The answer should be above. Officer Sato moved a chair and stood up to look at the top of the bookshelf, "It's duct tape and thumbtacks." Then he jumped down, "Then the line should be in it." As he spoke, he went to the side of the exercise machine, pulled out a knotted fishing line from the shaft and pulled it to the top of the bookshelf, "In this case, if Mrs. Masuo steps on the exercise machine, she can pull this bookshelf down and let the knife stick into her body." ”

"But that's not right," said the Shiratori police department, "and although there is a bookshelf full of books next to that shelf, it won't go in any other direction, but the more you pedal on the car, the harder it gets, the victim should find out." ”

"The resistance of this kind of sports car is very large, and when the line is rolled in, the resistance is even greater, and this kind of movement will generally maintain a constant speed, so when Mrs. Masuo is distracted on the phone, she will still subconsciously maintain a constant speed, so that she finally pulls down the bookshelf behind her. Officer Sato said, "In other words, the person who called Mrs. Masuo to distract him, that is, Mr. Masuo, you are the creator of the incident." ”

"Hey, hey, Madame Masutail is not blind, how can she not see such a long line?" asked Maori, "and you can see the knife there, right?"

"And what about this?" Conan pulled out a sign from the cabinet that read "Target Two Kilograms".

"By the way, if you put this on top of the knife," the Shiratori Police Department put the sign on top of the knife, "If you don't pay attention, you won't be able to see the knife at all." ”

Officer Takagi laughed, "And Mrs. Masuo is likely to be highly short-sighted." ”

"And I don't like to do sports with glasses on my glasses so that the sweat doesn't drip on it. Officer Sato laughed.

"I see," said Maori, "that must be Mr. Masao, who knows about Mrs. Masao." ”

"So, that's how the whole thing should be. "After Mr. Masuo laid the trap, he went to the Metropolitan Police Department to call back to make an alibi, and then came back and changed the scene. Even if the other police officers arrive at the scene first and see the bookshelves and books falling to the ground, it is easy to interpret it as an argument between the prisoner and the victim, and the tape and pushpins can also be understood as being prepared for the weight loss brand, but the fishing line must be recycled, so you will break Sato and Takagi as soon as you come. ”

"You pry out the pushpin and take out the fishing line, and then put the pushpin back in its place, and in the process, the tool used to pry the pushpin must be stained with blood," the Shiratori police department searched for the cabinet under the long table and found a small driver in the corner, "It seems that this is it." ”

"Y-How do you prove that I've used it. Katsura Massuo shouted.

Maori laughed, "Although we can't prove that you used it, someone can." ”

Glancing at the camcorder in Oda Haruko's hand, Katsura Masuo was suddenly deflated.

The Shiratori Police Department asked, "So, Mr. Masao, why did you kill your wife?"

Katsura Masuo said: "For the sake of the insurance money, I bought a high amount of insurance money for her, so I gave my wife to ...... under the pretense of a bank robbery."

"Please, you're lying too badly. Hattori laughed, "It must have been your wife who found out who the bank robber was and had something to do with you, so she blackmailed you." And the reason why the hostages were changed at that time was not because of fierce resistance, but because she was the wife of the mastermind. ”

"I see," Mori said with a smile, "the bank manager and his friend teamed up to rob their own bank store, of course the plan went well, but unfortunately, when the plan was carried out, your friend took your wife, who happened to go to the bank, hostage, and unfortunately your wife recognized your friend at once, so she dared to resist fiercely." ”

"Looks like so, that's right. Shiratori said, then asked, "Mr. Masao, why did you rob the bank store you managed?"

"Alas. Masuo Katsura sighed, "It's not because I need money, it's all forced by Kadai, I'm just the store manager, just managing the bank store, but she thinks I'm opening a bank and squandering extravagantly." And in order to satisfy her extravagance, I used my power to do some private work before, and after she found out, she became even more presumptuous, and this time she blackmailed me again, so I planned to kill her. ”

"I see. Shiratori said.

Katsuizo said to Oda Nobue, "Can you tell me what happened? Why didn't Kayo die? You know, I've done a lot of experiments to determine that I can kill her with one blow." ”

Officer Sato said, "Miss Nobue, now that the incident is settled, you can tell me why I want to participate in this reasoning game." ”

"The incident is settled, but please wait a little longer. Oda Nobue smiled bitterly.

"What the hell are you doing?" asked Officer Sato.

"Testing a new technology," says Sakurako Oda, "is to wirelessly transmit images from here to a distance." ”

"Uh, you can't be the Metropolitan Police Department's Matsumoto manager in the distance, right?" asked Officer Takagi.

"If only it could be that far. Haruko Oda sighed.

"It's nearby. Oda Nobue said, "But I'll give it to Matsumoto Administrator later." ”……
