Detective Conan: The Grey Winged Angel

　　 On Tuesday, January 5th, in the afternoon, at Dr. A's house.

Hearing what Huihara said, Dr. Akasa smiled and said, "Just ask my friend at Nanyang University about that kind of thing." Then I called my friend and asked the address and phone number of Professor Masami Hirota. Dialed the phone number of Professor Hirota’s home.

　　 "Hello, I am Dr. Aka, I am..." Dr. Aka looked at Huihara.

　　 "Miyano Akemi." Huihara said sadly.

　　 Miyano Akimi! Conan was taken aback.

"I am a friend of Ms. Akemi Miyano. I found a floppy disk missing during the New Year's cleaning. I remember that I accidentally sent it to Ms. Akemi before. I remember she mentioned that she sent you all the floppy disks. That floppy disk has some meaning to me, I want to get it back." Dr. A Li asked, "I wonder when it will be convenient for you?"

　　 "Oh, it's Mingmi's friend, I do have a strange floppy disk here." Professor Hirota laughed, and then he hiccuped.

　　 "Yes, that's it." Dr. Aka asked, "Then may we get that floppy disk now?"

　　 "No problem," Professor Hirota smiled, "Just wait for two or three guests to come, you better be there after that."

　　 Dr. Aka asked: "Then, can we visit in three hours?"

　　 "Three hours? Okay." Professor Hirota said.

　　 "I'll see you then." Dr. Aka smiled.

　　 When Dr. Aka hung up, Conan called back to the Maori detective office.

　　 "This is the Mori Detective Agency, I'm the detective Kogoro Mori, do you need any help?" Mori asked skillfully.

　　 Conan Khan came down, "It's me, uncle." Then he moved the receiver away from his ears.

　　 "Asshole!" Maori shouted, "What time is it now, and you won't be home after school. Where are you now?"

"I'm at Dr. A Li's house. I want to go out with Dr. A Li at night. I won't go back at night. When Sister Lan comes back from school, please tell me, Uncle." Conan said, and then hung up without waiting for Maori to shout at him On the phone, "Really, isn't there a caller ID?"

　　 "Ha," Huihara said with a sorrowful smile.

　　 "Thanks to you." Conan said grimly, "You will experience it later."

　　 "Alright, let's go." Dr. Aka said, "Shizuoka Prefecture, it's really far enough, I don't know if I can get there in three hours."...

　　 On the road, Dr. Ari’s car.

　　 glanced at Hui Yuan Ai, who was lying on the back seat and looking backward from the rear window. Conan in the passenger seat whispered to Dr. Aka who was driving, "Doctor, you can't be careless about that woman."

　　 Dr. Ari asked: "Does that woman mean mourning?"

"Even though she said she escaped from the organization, she didn't tell us anything about it. I asked her just now without answering a word. Although what the guy said earlier doesn't sound like a lie, after all There is no need for the organization to send someone like her to approach me." Conan said, "but I don't trust her."

"Uh, this, you are a little late." Dr. A Li smiled, "At least until she reaches adulthood, she will always live with me. Yingli called at noon and said that the preliminary procedures have been completed. If nothing else, I will be my family in the future."

　　 "What?" Conan was taken aback, "When did you run into her?"

　　 "New Year's morning." Dr. Aka said, "I was woken up by Yamazaki's phone when I was sleeping well."

　　 "New Year's morning?" Conan frowned, "Why is Yamazaki running to Futtsu City?"

　　 "How do I know this?" Dr. Ari said, "Later, I took my grief to the Meidai restaurant and asked Meizi for a favor." Then he said, "I wanted to find a chance to tell you, but you just went to Hawaii."

　　 "That's it," Conan said. ...

　　 At night, near Masami Hirota’s house.

　　 At the suggestion of Aihara, Dr. Aka parked the car two blocks away, and then took Conan and Aihara on foot to Hirota Masami's house.

　　 "Why are you stopping the car so far?" Dr. Aka complained.

　　 "My sister taught me, you must be careful when you come across things related to the organization." Huihara said sadly.

　　 "Will they come too?" Conan asked.

　　 "I don't know." Huihara said sadly, "But the organization should have a record of sending things to my sister." Then Conan frowned and asked, "What's wrong?"

　　 "Maybe," Conan said, then changed his words, "It's nothing." At the same time, I thought, maybe it's this floppy disk... it's better not to let her know about this.

　　 Around seven ten in the evening, Masami Hirota’s house

　　 After Dr. A Li rang the doorbell, a blessed middle-aged woman came out and answered the door.

　　 "Good evening." Dr. Aka said.

　　 "It's Mr. Akasa, I'm Hirota Toshiko," Hirota Toshiko smiled, "I have heard about you from my husband, please come in, please come in."

　　 "Excuse me," Dr. Aka said, and then exchanged shoes with Conan and Huihara.

　　 Hirota Toshiko smiled and said, "My husband is in the study, I will take you there."

　　 "Thanks a lot." Dr. Aka asked, "have all the guests gone back?"

　　 "I just came back." Hirota Toshiko smiled, "It should be all gone."

　　 "That's good." Dr. Aka said.

　　 While talking, when the study arrived, Hirota Toshiko pushed the door and did not open it, and no one answered the door. "Strange, what the **** was doing inside, and the door was locked."

"Help me, doctor." Conan looked at the window on the door and said, then climbed up with the help of Dr. Aka, and found that it was also closed. Then he looked into the room through the window and was immediately taken aback. In a mess, a middle-aged man was crushed under a bookcase with a pool of blood near his head.

　　 Conan jumped off the door frame and eagerly asked Hirota Toshiko: "Where is the spare key for this room?" Then, after hearing Hirota Toshiko said that there was no spare key, he greeted Dr. Akasa and asked him to help knock the door open.

　　 "Husband!" Seeing the scene in the study, Hirota Toshiko ran in in exclamation, probed Professor Hirota's breath with a trembling hand, and then burst into tears.

　　 "Doctor, call the police." Conan began to check the scene, Hui Yuanai turned over the computer desk, then turned on the computer, stood on the chair, tapped the keyboard with his fingertips, and quickly checked.

　　 Soon after, Hui Yuanai turned off the computer and jumped down, and said to Conan, "All the floppy disks are gone, there are no travel photos in the computer, and nothing we are looking for."

　　 "Did they do it?" Conan said.

　　 "Impossible." Huihara said sadly, "If it burns up here, they might have done it."

　　 "Why?" Conan asked.

　　 "Although the data on the computer hard disk is deleted, it can still be recovered." Aihara said, "Taking the hard disk away is too conspicuous. It is reasonable that an accidental fire burns the hard disk."

　　 "That's it," Conan said.

　　 More than ten minutes later, the Henggou Police Department of Jinggang County led a team and ordered his subordinates to start work and ask Hirota Toshiko and Dr. Aka about the situation.

Hirota Toshiko said: "I went to my friend's house to pay New Year's greetings at about 4 in the afternoon, and came back at about 7 in the evening, and then Dr. A Li came over, and then I took him to the study, and then found that the door could not be opened, then The child climbed onto the door, and then he and Dr. Ari banged the door open...."

　　 "So that's it." Henggou Police Department asked, "Do you know Dr. Aka?"

　　 Hirota Toshiko said: "I saw you for the first time today. He called this afternoon, so I know his name."

　　 "So, how many visitors are there today?" Henggou Police Department asked.

　　 "A lot of people come to visit us today. My husband is a university professor, a former student, a current student, and friends," Hirota said, "I ate here at noon and drank a lot of wine."

　　 "Then, who has been here since you left?" Henggou Police Department asked.

"I heard from my husband that there seem to be three or four guests coming, including this Mr. Aka." Hirota Toshiko said, "By the way, I ran into Mr. Hosiya and Hiroshi when I left. He was before my husband. Students, they work in securities, no one else knows."

　　 "Is there his phone?" Henggou Police Department asked.

　　 "Yes." Hirota Toshiko said.

　　 "Then you call him immediately." Henggou Police Department said, and then asked Dr. Ari, "So, are you here?"

"I have a friend who accidentally sent my floppy disk to Professor Hirota. I just came to Shizuoka Prefecture to play and retrieved the floppy disk by the way." Dr. Aka said, "Anyway, I have nothing to do with this incident. , There will never be a fool who brings two children to kill."

　　 "That's true." Henggou Police Department said, and then looked at Conan and asked with some surprise, "You are by Mr. Maori, so Mr. Maori is here too?"

　　 "No, no," Dr. Aka said, "I brought them here alone this time."

　　 "That's it," Henggou Police Department said, "It's a pity."

　　 At this time, a forensic officer reported, "Police Department, you can go in now."

　　 "How about? Is it a secret room?" Henggou Police Department asked.

　　The forensic officer smiled and said, "An authentic secret room."

　　 "Secret room?" Hirota Toshiko asked, "What is that?"

　　 "The secret room murder case, also known as impossible crime." Conan said excitedly.

　　 "What!" Hirota Toshiko was surprised.

　　 Entering the room, Henggou Police Department said to the forensic personnel: "Tell me about the situation."

　　The forensic officer said: "All the doors and windows here are locked properly. If this is the case when you come in, then this is a standard secret room."

　　 "Have you touched anything since you came in?" The Yogomi Police Department asked Hirota Toshiko and Dr. Aka.

　　 "No, no." Hirota Toshiko and Dr. Aka said together.

"There are no fingerprints on the murder weapon. It is an ornament. If there is no fingerprint, it can be said that it has been wiped during the Chinese New Year. But there are no fingerprints on the handle on the inside of the door. There is only a set of fingerprints on the handle on the outside of the door. "The forensic officer said, "So I believe it is a secret room."

The Henggou Police Department said: "Yes, someone killed Professor Hirota and wiped off the fingerprints. Otherwise, there will be no fingerprints on the handle on the inside of the door, and there will not be only a set of fingerprints on the handle on the outside of the door. "

"There is also a fixed phone ~www.NovelMTL.com~ which is turned upside down on the ground, covered with a book, and there are four telephone recordings. A person called Shirakura called two calls, one called Morioka People made two calls. I think the call from the white warehouse is very strange. You will know after hearing it." The forensic officer said, "Also, there are no fingerprints on the fixed phone."

　　 "In other words, the murderer didn't know why he touched the fixed telephone." Henggou Police Department asked, "What about the key?"

"The key is under a hard-shell notebook in front of the fixed phone, about two meters away from the door. It is speculated that the key came in through the crack of the door, but how did the key get in and how did it get under the notebook? That's your problem." The forensic officer smiled, "That's it for now."

　　 Officer Henggou asked, "Wait, what's the time of death?"

　　The forensic officer said: "The air conditioner is hit very high here, and the time of death of the deceased is not easy to determine. The results will only be available after an autopsy. For reference, push forward about three hours, that is, after 4 o'clock in the afternoon."

　　 Police officer Henggou said angrily: "If you say it, you don't say it."

　　 "So I didn't say it just now." The forensic officer smiled.

　　 Police officer Henggou listened to the recording of the phone and asked: "Ms. Hirota, Mr. Shirakura and Mr. Morioka are..."

　　 "Shirakura should be my husband's current student, called Shirakura Yo." Hirota Toshiko said, "Morioka is Morioka, he is a veterinarian, and often comes to play chess with my husband."

　　 "Do you have their phone number? Please call and let them come." Henggou police officer said. ...
