Tuesday, January 5th, afternoon, at Dr. Asasa's house.

Listening to Ashara's words, Dr. Asa smiled and said, "Just ask my friends at Nanyang University about that kind of thing." Then he called a friend and asked for Professor Hirota's address and phone number, and then dialed the phone number of Professor Hirota's house.

"Hello, I'm Dr. Asasa and I'm ......" Dr. Asa looked at Ashara.

"Akemi Miyano. Gray Yuan said.

Akemi Miyano!Conan was taken aback.

"I'm a friend of Miss Akemi Miyano, I found a floppy disk missing during the New Year's cleaning, and I remembered that I accidentally sent it to Miss Akemi before, and I remember that she mentioned it, saying that I sent you all the floppy disks, and that floppy disk means something to me, and I want to get it back. Dr. Asa asked, "I wonder when you're going to be convenient?"

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

"That's right, that's it. Dr. Asasa asked, "Can we go over and get the floppy disk now?"

"No problem," Professor Hirota laughed, "just wait for two or three guests to come, and you'd better arrive after that." ”

Dr. Asa asked, "Is it okay for us to visit in three hours?"

"Three hours? Professor Hirota said.

"I'll see you then. Dr. Asa laughed.

When Dr. Asa hung up, Conan made a call back to the Maori Detective Agency.

"This is the Maori Detective Agency, I'm Detective Maori Kogoro, do you need any help?" asked Maori expertly.

Conan Khan came down, "It's me, uncle." "Then keep the earpiece away from your ears.

"!" exclaimed Maori, "what time is it, and you don't come home from school, where are you now?"

"I'm at Dr. Asasa's house, I'm going out with Dr. Asa at night, and I won't go back at night, and when Sister Lan comes back from school, please uncle, you and her. Conan said, and without waiting for Maori to yell at him, he quickly hung up the phone, "Really, isn't there a caller ID?"

"Ha," Gray Yuan said with a smile, "the child's life is good." ”

"Thank you for it. Conan said angrily, "You'll experience it later." ”

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

On the way, Dr. Asasa was in his car.

Glancing at Ash Hara, who was lying in the back seat and looking back from the back window, Conan in the passenger seat whispered to Dr. Asasa who was driving, "Doctor, you can't be careless with that woman." ”

Dr. Asa asked, "Does that woman mean mourning?"

"Although she said that she had escaped from the organization, she didn't tell us anything about it, and she didn't answer anything when I asked her just now. Although what that guy just said didn't sound like he was lying, after all, the organization didn't need to send someone like her to approach me. "But I'm not comfortable with her." ”

"Well, well, you're a little late. "At least until she's an adult, she'll live with me." Yingli called at noon and said that the preliminary procedures had been completed, and if nothing else, it would be my family after mourning. ”

"What?" Conan was taken aback, "when the hell did you run into her?"

"The early hours of the New Year. Dr. Asasa said, "I was asleep when I was woken up by a phone call from Yamazaki. ”

"New Year's morning?" Conan frowned, "What is Yamazaki going to do in Fuzu City?"

"How do I know that. "Later, I took Wai to Mei Dai Restaurant and asked Miko for a favor. He continued, "I was looking for a chance to tell you, but you happened to be on your way to Hawaii. ”

"I see. Conan said. ……

At night, near Masatsumi Hirota's house.

At Ashara's suggestion, Dr. Asasa parked his car two blocks away, and then walked with Conan and Ashbara to Masami Hirota's house.

"Why do you have to park so far away? Dr. Asa complained.

"My sister taught me that you must be careful when you encounter something related to the organization. Gray Yuan said.

"Will they come too?" asked Conan.

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

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

At about 7:10 p.m., Masami Hirota's house

After Dr. Asa rang the doorbell, a middle-aged woman with a fortune came out to answer the door.

"Good evening. Dr. Asasa said.

"It's Mr. Agasa, I'm Noboriko Hirota," Noboriko Hirota smiled, "I've heard about you from my husband, please come in, please come in." ”

"Excuse me. Dr. Asasa said, and then swapped shoes with Conan and Ashbara.

Noboru Hirota smiled: "My husband is in the study, and I will take you there." ”

"Thank you. Dr. Asasa asked, "Have all the guests returned?"

"I've just come back. Noboru Hirota smiled, "I think they're all gone." ”

"That's good. Dr. Asasa said.

While talking, the study arrived, Hirota Noboru pushed the door but didn't push it open, and no one answered when he knocked on the door, "It's strange, what are you doing inside, and you locked the door." ”

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

Conan jumped down from the door frame and eagerly asked Noboru Hirota, "Where's the spare key for this room?"

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

"Doctor, call the police. Conan began to inspect the scene, and Gray Hara flipped through the computer desk, then turned on the computer, stood on the chair, and tapped the keyboard with his fingertips, quickly checking it out.

Soon after, Gray Yuan closed the computer and jumped down, saying to Conan, "All the floppy disks are gone, and there are no travel photos on the computer, and there is nothing we were looking for." ”

"Did they do it?" said Conan.

"No way. "If this place burns down, it's possible that they did it." ”

"Why?" asked Conan.

"Although the data on the computer hard drive is deleted, it can still be recovered. "Taking away the hard drive is too conspicuous, and it makes sense that an accidental fire burned the hard drive." ”

"I see. Conan said.

Ten minutes later, the Henggou Police Department of Gonggang County led a team over, and instructed his subordinates to start work and ask Noboru Hirota and Dr. Asa about the situation by themselves.

"I went to a friend's house around 4 p.m. and came back at about 7 p.m., and then Dr. Asa came over, and then I took him to the study, and then I found that the door wouldn't open, and then the kid climbed up to the door, and then he and Dr. Asa slammed the door open. ……”

"I see. The Henggou Police Department asked, "Do you know Dr. Asasa?"

Noboru Hirota said, "I met him for the first time today, and he called in the afternoon, so I know his name. ”

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

"A lot of people came here today to pay New Year's greetings, my husband is a university professor, a former student, a current student, and a friend," said Noboriko Hirota. ”

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

"According to my husband, it seems that there are three or four guests coming including this Mr. Asasa. Noboriko Hirota said, "By the way, when I left, I ran into Mr. Hosoya and Hiroshi, who was a former student of my husband and was engaged in securities, so the others didn't know about it. ”

"Is there a phone number for him?" asked the Henggou Police Department.

"Yes. Noboru Hirota said.

"Then call him right away. The Yokogou Police Department said, and then asked Dr. Asasa, "So, are you here?"

"I had a friend who accidentally sent my floppy disk to Professor Hirota, and I just came to Shizuoka Prefecture to play and retrieve the floppy disk by the way. "Anyway, I have nothing to do with this incident, and there will be no fool who comes to kill people with two children." ”

"That's right. The Henggou Police Department said, then looked at Conan and asked with some surprise, "You are from Mr. Maori's side, so Mr. Maori is also here?"

"No, no. "I brought them here alone. ”

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

At this point, an forensic officer reported, "Police, you can go in now." ”

"How's it going? Is it a secret room?" asked the Henggou Police Department.

The forensic officer smiled: "Authentic secret room." ”

"The secret room?" asked Noboriko Hirota, "what is that?"

"Murder in a closed room, also known as impossible crime. Conan said with some excitement.

"What!" Noboru Hirota was taken aback.

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

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

"Did you touch anything since you came in?" the Yokozo Police Department asked Noboru Hirota and Dr. Asasa.

"No, no. Noboru Hirota said with Dr. Agasa.

"There are no fingerprints on the murder weapon, it is an ornament, and there are no fingerprints that can be said to have been wiped during the New Year. However, there are no fingerprints on the handle on the inside of the door, and there is only a set of fingerprints on the handle on the outside of the door. "That's why I think it's a secret room." ”

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

"There was also a landline, reversed on the floor, covered with a book with four recorded phone calls. A man named Hakura made two calls, and a man named Morioka made two calls, and I thought the call from Hakura was very strange, and you will know it when you listen to it. "Also, there are no fingerprints on the landline phone." ”

In other words, the killer did not know why he touched the landline. The Henggou Police Department asked, "What about the key?"

"The key is under a hard-shell notebook in front of the landline, about two meters away from the door, presumably the key was sent in through the crack in the door, but how the key got in, and how did it get under the notebook, that's your problem. The forensic officer laughed, "That's it for now." ”

Officer Yokogou asked, "Wait, what about the time of death?"

The forensic officer said: "The air conditioning here is very high, the time of death of the deceased is not easy to determine, and the results will be obtained after the autopsy. ”

Officer Henggou said angrily: "This is equivalent to not saying it." ”

"That's why I didn't say it just now. The forensic officer laughed.

Officer Yokomizo listened to the recording of the phone call and then asked, "Mrs. Hirota, Mr. Shirakura, and Mr. Morioka are ......?"

"Shirakura should be my husband's current student, called Hakura Yang. "Morioka is Michio Morioka, and he is a veterinarian who often comes to play chess with my husband. ”

"Do you have their phone number? Please call them and tell them to come. Officer Yokogou said. ……
