"Then who killed my husband?" "There is no spare key in this room..." Mrs. hiroda asked, clutching Henggou


    "Well," Heng Gou glanced at Gao Cheng and said with a dry smile, "calm down, madam. Aren''t we investigating? Has anyone suspicious visited the professor tonight? "


    "In addition to a few detectives from Chenghu, it seems that there are two or three people coming here," Mrs. hiroda replied, pointing to Gao Cheng. "Because I just went to the town meeting, I''m not very clear..."


    "Town meeting?"


    "Yes, I went with the ladies nearby. I went out at eight and came back at eleven. When I went out, Mr. Chenghu just called."


    "Madam, you didn''t see the guest who came to see your husband tonight, did you?" The transverse groove has a headache.


    "I''ve seen the first guest here," Mrs. hiroda recalled. "At that time, my wife and I just went out. My husband said that he was a student of his past, like his surname is Xiya... I just heard that he would have two or three students come to see him..."


    "It''s gone," said Huiyuan, checking the computer beside him. "Not only are all the disks missing, but even the data in the computer seems to have been washed out!"


    "Ah?" Henggou was surprised when he heard the words. He looked back at Huiyuan, who is this child


    "She''s my assistant." Gao Cheng squatted beside the body and said as he looked at the scene.


    "Help, assistant?" Henggou pointes at Huiyuan and Gaocheng stupidly, and says with a dry smile, "detective Chenghu... Is really a detective. This child seems to be very powerful..."


    "Officer Henggou," Gao Cheng said, looking at the telephone on the ground with a book on it, "it''s like an answering machine. Can you listen to the recording of the answering machine first?"


    "Oh, it has been verified on the spot, and now it''s no problem to flip." Henggou reaction, quickly wearing gloves to press the answering machine button.


    "There are 13 messages..."


    The investigation is going on in an orderly way, but Gao Cheng thinks about the people in black.


    Once you are watched by those guys, things will become quite troublesome, not only him, but also the people around you will be in danger.


    "You''d better not meddle in this case," Huiyuan reminded. "They''re probably still staring here now..."


    "You think those guys did it?"


    "Most likely, as you said before, it''s not difficult for them to find the disks, because the records of the lost disks and the records I sent out at that time are all left in the organization."


    Huiyuan said, looking at Gao Cheng: "anyway, if you are involved in the case of the organization, it''s still too dangerous for you."


    "It''s too early to say that," Conan said, shaking his head. "It''s not sure they''re involved. This case doesn''t look like they wrote it."


    "What''s the matter, please?" A young man appeared at the door, "I''m Bai Cang who made an appointment with the teacher..."


    "You are white warehouse? Professor hiroda has been murdered, perhaps by a visitor. "


    Henggou heard 12 phone messages one after another, and said in a deep voice: "Mr. Shenggang has 2 calls, but Mr. baicang, you have 10 calls. Is that too much?"


    "Well," the young man said anxiously, "because I have played many times and no one answered, so I came to have a look. I didn''t expect that the teacher would have an accident."


    Henggou looked at the young man suspiciously, continued to check the message and said, "next is the 13th pass, the last message."


    "Drop! Hello... I''d like to explain to you about our new... Insurance products... Can you spare some time... I''ll call again... "


    "It''s an insurance salesman." Henggou frowned and turned to ask the police officer to find Shenggang in the message, as well as Xiya who visited at the beginning.


    "No," Conan said, "although the voice has changed a little because of the machine, the tone... The voice..."


    "Vodka," Huiyuan said suddenly, "it''s the sound of vodka. It seems that they didn''t do this event. If they do, the first task is not to set up the secret room, but to get back the recording tape with sound record."


    Conan also followed: "that is to say, they haven''t come here yet?"


    "If there is a police investigation here, they will probably have a headache," Huiyuan said with a smile, "because now the tapes can''t be recovered, and even the magnetic discs are missing."


    "Organization..."


    Gao Cheng couldn''t get a word in, just mumbling about his impression of Conan Li''s black dress organization.


    It used to be seen as a joke, because the main characters, except qinjiu, are either undercover or unreliable. There are also many people who betray the organization. But when they face it, they still feel very mysterious and terrible.


    Black organization hidden in the dark, not just animation so simple, otherwise had been undercover end off.


    At least it''s not too difficult to deal with him as a little detective.


    Gao Cheng''s eyes narrowed slightly.


    The killers of this organization are not as easy to deal with as the female killers who used steel wires as weapons


    With his little hand on his back, Huiyuan turned to Gao Cheng, who was silent. His cold eyes tightened slightly: "forget it, lock the door outside the room, and get the key into the middle of the room, and it''s just under the notebook. It''s impossible in Physics..."


    "Impossible?" Gao Cheng came back.


    "Yes, even if you use the tape on the answering machine, you can''t do it. Although there are many doubts, it''s not entirely impossible to take into account that after drinking, I fell down with the bookshelf and hit the back of my head


    Huiyuan didn''t want Gao Cheng to continue to mix in. He closed his eyes and whispered: "it''s dangerous to stay here. Chenghu, you can''t go on like this..."


    "No way?" Gao Cheng picks his eyebrows and sweeps the scene of the murder.


    Indeed, as Huiyuan said, this secret room is very different. Professor Guangtian''s body is full of alcohol. It seems that it is really an accident. But what officer Henggou said is also very reasonable. With him in... Or Conan in, the possibility of an accident is quite small, especially when there are many doubts at the scene.


    Henggou also questioned several visitors, including young Bai Cang, who left too many messages on the phone, the first one to visit securities company section chief Xi Ya, and veterinarian Sheng Gang, who often played chess with Professor Guangtian.


    All three are suspects


    Gao Cheng stands by the answering machine with his mouth tightly pursed. He sees the identification personnel investigating the tape of the answering machine.


    The suspicious part of the tape is that the sound is intermittent. The killer may have used the tape to do something


    All the doors and windows of the room are locked. The only way to let the key into the room from the outside is a little gap under the door. It is impossible to press the key under the notebook by using the tape.


    Gao Cheng turns his eyes to the bookshelf and the scattered books, frowning and silently closing his eyes.


    Open your eyes again, all the details of the whole murder scene emerge in front of Gao Cheng''s eyes.


    Bookshelves, murder weapons, corpses, scattered bookshelves, inverted telephones, intermittent audio tapes, room keys crushed by notebooks


    The superfluous details gradually disappeared, leaving only the notebook connected with the door and the answering machine.


    Gao Cheng''s eyes fell on the chess pieces scattered around his notebook, and all the details in his mind began to reappear the scene.


    "Come on," Huiyuan urged, "let''s get out of the back door quickly..."


    "You guys go first," Gao Cheng said to Conan gray field and Dr. Ali as he withdrew from his thinking space. "I''ll handle this next."


    "Eh?" Huiyuan stares at Gao Cheng.


    "Have you solved the murderer''s technique?" Conan surprised way, he is also very sure is not an accident, but the secret room technique is stuck, how also can''t open.


    "I have a special way of reasoning."


    Gao Cheng bent down and picked up a chess piece: "these chess pieces are the key, the key and the chess pieces around the notebook are not meaningless, scattered randomly, the truth of the fact..."


    In Conan''s eyes, Gao Cheng picked up his notebook, put three chess pieces in front of the answering machine to form a triangle, then turned to Mrs. hiroda and asked, "do you have any spare tapes?"


    "Ah," Mrs. hiroda said, "yes, it is. My husband seems to be in the drawer under the computer..."


    "What''s this?" Conan stares at the chess pieces, his face shakes, and a light flashes in his mind.


    Gao Cheng got the spare tape and began to arrange it in the crowd of Henggou police officer and others. First, he pulled the tape out of the tape to a sufficient length, then put the tape into the answering machine, and then pulled the exposed tape straight out of the door and through the key ring.


    "Can I help you, Conan?"


    "Good!"


    In response, Conan raised his hand, ran to the door in front of officer Henggou''s puzzled sight, pulled the strap through the key ring back to the study, and finally put it on a chess piece close to the phone. Finally, he put his notebook on a chess piece placed in a triangle.


    Huiyuan embraces his arm and takes a panoramic view of the whole layout. He says with a smile, "are you going to use the power of the tape to pull down the pieces? This is only theoretical. The base of chess is very stable, so before falling down, the key will be taken out of the notebook with the chess pieces, and it won''t be pressed under the notebook at all... "


    "The other way round?" Conan further arranged, "although the head of the chess piece is round, as long as the notebook material is hard paper, it should be able to support stably."


    Huiyuan saw Conan''s arrangement, his eyes narrowed, and then he looked straight at Gao Cheng at the door.


    Gao Cheng took out his mobile phone and said, "let''s have a practical experiment now."


    After closing the door and using the key wearing the belt to simulate locking the door, Gao Cheng places the key in front of the crack in the door, and then calls the room phone with his mobile phone to leave a message.


    As the answering machine starts, the tape rolls back automatically, and the key is pulled from the crack of the door to the notebook supported by the chess pieces. When it reaches the bottom of the notebook, it soon bumps into the chess pieces


    "In, in!" Henggou police officer and several suspects watched in horror as the key was pressed under the notebook and three pieces fell around the notebook. Everything was similar to the original scene. Even the rest of the tape was rolled into the tape recorder“ "Of course," Gao Cheng went back to his study. "This technique may surprise people at first sight, but it''s not particularly ingenious. I''m afraid it''s just a temporary way for the murderer to think of when he was flustered. That''s why he left a lot of suspicious places and even decisive evidence..." Mr. Bai Cang, who left 10 messages, You are the murderer“ Wait, wait a minute! " Young Bai Cang stood in the crowd and suddenly became the focus. He was pale and said with a dry smile, "what kind of evidence is this? I just left a lot of messages... "" then why did you specially run back to the scene? " Gao Cheng interrupted“ Didn''t I say that? Of course, it was because the phone couldn''t get through all the time that I came here... "Bai Cang looked at Gao Cheng, his voice became smaller and smaller, and his teeth began to tremble involuntarily“ Is it because you want to get back the tape with your fingerprints? " Gao Cheng continued, "I was going to be the first discoverer with Mrs. hiroda, but I didn''t expect anyone to find out ahead of time. Even the police arrived. Am I right? As for the motive, I''m afraid it''s the disks... "" all the disks are in the car outside me, "Bai Cang said helplessly, gripping his fist and teeth." it''s all because of that picture. "“ That picture? "“ When I was a model, I changed my face and even my name, but the photos of my face were left with the professor... "" so I killed the professor because of this? "“ How is that possible? " Bai Cang said, "recently, the magazine has planned an activity. I originally wanted to ask the professor to borrow the photos of men disguised as women on my university anniversary. Because of the relationship between makeup and wig, I can''t see the original appearance, and it''s quite special... But the professor said..." Bai Cang looked at professor hiroda on the ground and said: "I''ve forgotten which disk to scan your photos of men disguised as women, If it''s an ordinary photo sent to you, it can be found immediately. Do you want me to send it directly to the editorial department? ", He teased me so drunk that when I came back, he had fallen in front of me... "Bai Cang said with a bitter smile:" next, like detective Chenghu, you said, it''s really hasty, but I didn''t expect that a famous detective would come and see through my technique. It''s really ironic. " Henggou solemnly put handcuffs on baicang: "let''s go back to the police station."“ Hello, ah Cheng, "Dr. a Li reminded Gao Cheng anxiously," that disk still needs to be taken back! " Gao Cheng nods and finds the transverse groove alone. Although the evidence must be sent to the police station for investigation, it is not without negotiation, especially in the face of good people“ Officer Henggou, that disk has nothing to do with the case. Today, we are in a hurry to ask Professor Guangtian for the disk. Even if we take it away, it doesn''t matter? "“ This... "... outside the Chenghu detective office, Huiyuan quietly followed Gao Cheng downstairs. On the way back from Shizuoka County, Huiyuan bowed his head and said nothing. Gao Cheng stopped and looked back at the silent Huiyuan: "even if I didn''t get the disk back, I don''t have to be so sad, do I? I will try to find a way... "Huiyuan slowly raised his head, showing a small face with blurred tears:" why? Why didn''t you save my sister? " Gao Cheng''s pupils suddenly tightened, and he met Huiyuan''s crying eyes: "do you mean the one billion yen robbery? At that time, I... "Huiyuan grabbed Gao Cheng''s trouser legs and wailed:" you have such reasoning ability, you should easily see through my sister''s business! Why... Why? "“ It''s not that I don''t want to save it, it''s just that... "The dusty memory surged into Gao Cheng''s heart again, which was what happened before he crossed.
