(Girls' Literature) "Didn't I say that, Mr. Policeman? It's just because I didn't answer the professor's call that I called so many times. Mr. Shirakura defended himself.

"Then let's talk about another thing, judging from the voice, it seems that you are Mr. Morioka, and after making the call, you made another call here, saying that you came here directly to find Professor Hirota, right?" Officer Henggou listened to the recording and asked.

"Yes, yes, but when I came yesterday, I found that the door was locked, so I went straight back." Bai Cang rolled his eyes and said.

"When did you get here?" Officer Yokogou continued.

"It's like about ten o'clock." Bai Cang thought for a while and said.

"No, you're lying, I'm already home at ten o'clock!" Noboru Hongda explained on the side.

"Don't be so arbitrary, maybe I just left with my front foot, and you came back with your back foot." Mr. Shirakura said with an awkward smile.

Officer Yokozo squinted at the man, and then asked, "Then what is the purpose of your coming to Professor Hirota?" ”

"Oh, yes, to be honest, I'm working as a model now, and this time there was a magazine that said that it was going to do a report on the surprising side of models, so I thought that when I was celebrating my university anniversary, I once dressed as a woman and took a photo with Professor Hirota, and I knew that teachers have the habit of saving photos on disks, so I thought of borrowing that disk here." Bai Cang spoke very fluently this time, and it looked like he had practiced.

"Oh~, okay then." Officer Henggou glanced at him, looked back, and continued to look for other clues, but in his mind, this person became more and more suspicious.

It's like an undercover game, you have to say the same thing as the person in front of you when you speak in the back, how you listen to it and how you think there is a problem, and the speech is still vague, and the time and place are not explained.

"Madam, does the professor usually store the photos in the disk?" Officer Yokozo turned his head and asked to Noboru Hongtian and said.

"Yes, my husband will save all the photos he likes to the computer, and there are also student transcripts of university entrance exams in the mobile disk, and even the chess games with him and Mr. Morioka, as well as the wins and losses." Noboru Hongtian said beside him.

"In this way, the murderer took all the materials after killing Professor Hirota, which means that that is his motive for the crime." Officer Henggou stroked his chin and concluded.

"Mr. Hosoori, you just said that your daughter is going to apply for Nanyang University recently, right?" Yokozo asked to Hosoori.

"Yes." Hosoori nodded, with a little scared expression on her face, as if she didn't know why this matter had something to do with him again.

"In other words, as long as she can get the questions for the entrance exam, then she won't have a problem getting in, right?" Officer Henggou looked at him and asked.

"No, it's not like that, I've never thought of it that way, and besides, aren't there many other people who have been here besides us? Moreover, the professor usually uses the computer in the university, and maybe the professor himself brings these materials to the university. Hosoori explained to herself.

"It's possible, he might have brought the disk to the university, and there should be no special markings on it." Mr. Morioka continued.

"Besides, isn't this a secret room?" Mr. Shirakura also joined in the fun.

At this moment, the Henggou police officer, who was already stunned, immediately locked on to Bai Cang, looked at him as he approached, and said, "When did I tell you that this is a secret room?" How did you know this was a secret room? ”

"I... I listened to them. Bai Cang stammered a little and pointed at Jiao Wen and said.

"You may have found someone to defend yourself, and we didn't talk much from beginning to end, how did you hear that?" Jiao Wen looked at this guy who was a little flustered coldly and said.

"It's possible that he heard it from me, besides, Mr. Officer, didn't you all say that the only key to this place was pressed under a book, so how could we possibly kill someone?" Hosoori said suddenly.

"Yes, officer, this room is completely locked, if you doubt me, tell me how I put the key under the notebook." Hakura didn't know why Hosoori would suddenly testify for him, but his words were very favorable to him.

Officer Henggou fell into deep thought again, there doesn't seem to be much of a loophole in these words, so what is the problem...

"Hey, Conan, come on." Jiao Wen whispered to Conan.

"Me? Above? Where to? Conan replied confusedly.

"Oops, of course it's up to you to solve the case, that Bai Cang** is a criminal who is not far from ten, look at his annoying appearance, hurry up and find out his modus operandi." Jiao Wen looked at the guy who was arguing with Officer Henggou and said.

"Hehe..."Conan rolled his eyes, and then pondered about this case, the current suspicion is that the books in a room are so messy, but there is only a notebook on the line from the door to the phone, which is not very reasonable, and between every message on the answering machine on the second phone, why is there a small blank, so it seems that there is really a way... But with what support?

While Conan was pondering, Gray Yuan Wai suddenly thought of something, picked up a Western chess piece from the ground, walked to his side, and then put the front of the chess piece on the ground, "The three chess pieces around that notebook seem to be just enough to hold up the notebook." ”

After saying that, he walked to the side, Conan was stunned for a moment, instantly figured everything out, ran to Jiao Wen's side, and whispered a few words to him.

"Okay, the case was solved so quickly, I'll go and tell Officer Henggou to tell these guys not to go." Jiao Wen stood up and said.

When he walked to the side of Officer Henggou, he happened to hear the three people find all kinds of reasons and prepare to leave the scene first, "Hey, don't have it first, the doctor has already solved the murderer's murder method." ”

"Huh?" Officer Yokozo and the other three people, hearing his words, turned their gaze to Dr. Asasa.

Conan was already hiding behind Dr. Asasa at this time, and used a voice changer, imitating the doctor's voice.

"That's right, I already know exactly how this secret room was created and who is responsible for committing such a case." The Doctor said with his mouth open and in conjunction with Conan.

"Really, I just said that this is just an accident!" Mr. Morioka said impatiently.

"You're so naïve, it's because of this that laymen can't handle the case, I don't think Officer Yokogou thinks so, right?" Dr. Asa has Conan behind him, and that's called a confident one.

"Uh...... Definitely, right. Officer Henggou said very hesitantly, he didn't see what the problem was, but he was an insider, if the person in front of him really said some clues, if he didn't say what it would be embarrassing.

"This room is indeed a secret room, no matter how you look at it, it will be an accident, but the murderer can easily create a perfect secret room by using the tape of the answering machine and the chess pieces." The doctor said, pointing to the answering machine on the ground.

"The strap of the answering machine?" Morioka looked dazed, do you still need tapes for the recording now?

"That's right, the answering machine used in the professor's house is still a model many years ago, and it can be regarded as a small antique, all the recordings are stored on a tape inside, and the murderer used the tape of this tape to turn this room into a secret room." Dr. Asa said as he looked at the crowd.

"Facts speak louder than words, so let's put on a show for you." Gray Yuan Ai looked at these people and said next to her, she also understood this technique, and she was a little earlier than the big detective.

Then Gray Plains and Conan began to tinker with the things on the ground.

"First we need a mobile phone." Conan naturally walked up to Jiao Wen's side and took out the phone he had put in his trouser pocket.

Then, since there was only this tape in the answering machine nearby, Conan had to pull out the bag in the tape little by little with white gloves.

"First pull the tape out of the appropriate length, then attach the tape to the phone, of course, the tape should be placed outside, and then after straightening the tape, go to the outside of this door." Conan said as he walked.

"Then it's a matter of putting the circle on the key, going through this strap, leaving this key outside the door, and taking the rest of the straps back into the room, back to this, the position of the notebook." Gray Yuan mourned, followed and said, and then picked up the Western chess pieces scattered on the ground, and after placing them one by one, he put the notebook on it, of course, the strap was already on the periphery of the chess pieces.

"Of course, the most important thing here is to turn all these Western chess pieces upside down." Gray Yuan mourned, took those Western chess pieces, and gestured to the Henggou officer.

"Upside down?" Officer Henggou apparently didn't understand what it meant.

"That's right, although the head of the Western chess piece is round, because this notebook is a hard shell, it can still hold stably." Gray Yuan said after finishing the chess pieces.

Conan, who had been standing outside the door, also closed the door at this time, "The murderer first locked the door outside the door at this time, put the key on the floor, and then started to make a phone call. ”

Conan expertly unfastened it, locked the focal text, and then made a call to the answering machine, because no one answered, the landline immediately turned to the recording state, and then the tape that was pulled out began to be retracted inward.

"As soon as the answering machine is turned on in this way, the tape rolls inside, and it takes the key outside the door, through the crack in the door below, and then goes under the notebook that reaches the center of the design house, and then knocks down the flag at the front, upsetting the balance, and if my calculations are correct, the key will be crushed in it when the notebook falls." Conan said slowly outside the door.

"Suppressed!" Officer Henggou watched in amazement, and the whole incident happened just as the two children said.

Then he touched his chin and suddenly said, "I see, as long as the answering machine continues to work, the tape will be completely rolled up, and the evidence will naturally disappear." ”

"How? Are our experiments still going well? Conan pushed the door open and walked in from the outside.

"It's very smooth, and in this way, the murderer is also obvious, and the only one who can use this technique is to leave a white warehouse of ten recordings in the answering machine." Jiao Wen said in the room.

"You killed my husband!" Hongtian Noboru Shiko looked at Bai Cang angrily and said.

"This tape has traces of distortion everywhere before Conan's experiment, which is evidence of your use of this technique, you better admit it quickly!" Officer Henggou also looked at Bai Cang and said.

"Please wait a minute, Mr. Policeman, yes, this technique is really powerful just now, but how can you say that I did it, in fact, the only thing I did was to leave a few more recordings, and if I was really the murderer, how could I obediently come back here." Mr. Shirakura explained to Officer Yokozo.

"The reason for your justification is too nonsense, judging from the tape, there are obvious fingerprints on it, as long as you compare it with your fingerprints, it will be clear whether you did it naturally." Jiao Wen pursed his eyes and looked at Bai Cang and said, "And judging from this fingerprint, this crime should be an impulsive crime." ”

"Hey, it's all because of that photo, it's the photo of me dressed as a man, but I never expected that the package sent to me by the professor would include a note that said that you look like nothing more than that, and my face in the past, the face I haven't had plastic surgery!" Bai Cang lowered his head and explained his motive for killing.

"But when I went to the professor and asked him to give me the photo I needed, the professor said that he wanted to send the photo of my face, which I didn't have plastic surgery before, to the editorial department, so I just..."

"You can shut up, because it's a little thing to kill someone, and you're enough." Jiao Wen interrupted Bai Cang's words loudly, and then turned his head to look at Hosoori, "I'm more curious about Mr. Hosoori's reason for your perjury than your reason for killing?" ”

"Uh..."Hosoori hesitated twice, but still confessed, "I basically guessed from Shirakura's performance, he is the possibility of the murderer, so I want to use this reason to help him afterwards, and ask him to send me the entrance exams and test questions in the disk." ”

Jiao Wen pouted, this is a reflection of how much lack of legal awareness, for the entrance exam to make false testimony, don't you feel that the risks you take do not match the benefits?!
