Gao Chengchao''s haggard Yanjing Zhangwu nodded and looked at the scene of the murder. Because there were already forensic officers taking photos to collect evidence, he didn''t have to worry about damaging the scene.


    Inside, you can see a fat middle-aged man lying at the dining table, holding his throat in pain. Like many previous cases, it is very consistent with the characteristics of cyanide poisoning.


    On the table, a coffee cup is poured on the plate, and the coffee flows down the table to the chair, leaving two pools of dried coffee stains on the carpet.


    The strange place is the position of the chair. Both feet in front of the chair are soaked with coffee, but the right foot doesn''t coincide with the coffee mark on the carpet. It seems that someone has moved it.


    And it''s not moving until the coffee is dry


    Gao Cheng carefully looks at the coffee marks on the table, and suddenly infers that someone is sitting on the chair when the coffee is spilled. When the coffee drips to the right foot of the chair and leaves traces on the floor stand, he gets up and moves away the chair, and then some coffee drips to the left foot of the chair.


    This inference is also in line with the direction of coffee sprinkling, short on the right and long on the left


    Gao Cheng looks at the coffee cup on the table again and holds up the plate under it. He finds that the coffee mark below doesn''t match the shape of the plate. It''s almost the same to take off the plate, just like the cup pouring directly.


    Knowing that the first one to find is Yanjing Zhangwu, Gao Cheng''s eyes stop on Yanjing Zhangwu, who explains to Mu Mu Mu.


    According to the testimony of my uncle and the apartment administrator, the gate of the entrance was locked at that time, and the anti-theft chain was also hung. However, after breaking into the entrance, Yanjing Zhangwu ran in front of him and directly came to the living room.


    In addition, Xiaolan has been guarding at the door, no one else has escaped, and the only one who can do anything is Yanjing Zhangwu.


    In other words, it is because of the rush of time that many loopholes have been left behind. The technique of hiding any traces is rather crude.


    Gao Cheng took a look around the scene and went straight to the locked balcony French window.


    It''s still raining heavily outside. When you open the door, you can see that the parking lot is downstairs, and his car is right below.


    "Is this French window locked in the beginning?" Gao Cheng asked back.


    "Yes," muruna said, "but just in case, I opened and checked the balcony... In a word, this case also has the possibility of suicide, and it happens to be the same apartment..."


    "Please, please wait a moment, police officer," he asked urgently. "It''s possible to commit suicide... Isn''t that suicide? Because it''s a secret room... "


    "It''s not the same. If you hang yourself or cut your wrist in a secret room, it should be suicide, but it''s not necessarily poisoning. If the criminal comes to visit Mr. Nakamura with a cake and poisons his coffee, he leaves on the excuse of something urgent. When he goes out, he tells him that the neighborhood is not safe and asks him to hang up the anti-theft chain, so it''s not impossible to finish the killing in the secret room..."


    Mu Mu looked at a plate of cake placed beside the coffee cup on the table, explained it with great experience, and then asked Chang Wu in Ran Jing, "by the way, where were you at about 6:30 on the time of the crime?"


    "Me?" After sweating a lot, he asked himself, "I''m not well recently, so I didn''t go to the company, so I went to sleep at home. Then I got a confirmation call from Mr. Maori at about 6:30. I remember that I made an appointment with Mr. Zhongmu at 7:00 tonight, so I came here..."


    "Is that a home phone?" Mu Mu continues to ask a way.


    "No, it''s a cell phone..."


    "Can anyone prove that you slept at home all day?"


    "No..." Ranjing Zhangwu said, "are you doubting me?"


    "Just in case..."


    "Ah, yeah," Conan said suddenly, pretending to be surprised. "It''s so strange under the coffee cup and saucer..."


    "What''s so strange?"


    "It''s the mark of coffee overturning. Generally, if it is overturned on the plate, there should be a round mark below... There is no coffee on the plate..."


    Gao Cheng walks into the room from the balcony and hears Conan''s exaggerated voice. He looks at the curtain in front of the landing window.


    Just now, he found that the curtains on both sides were wet. It was obvious that the French window had not been closed when he found the body.


    Looking at Yanjing Zhangwu suspected by Conan, Gao Cheng frowned slightly.


    Taking advantage of the fact that the body was first found and doing so many tricks in a hurry, there is only one possibility except that I am the murderer


    "I don''t know for what purpose, but I know who did it?" Facing the puzzled eyes, Conan said with a few confident smiles, "after the coffee is dry, the only one who can do this kind of thing in the room is the first one to come in and find Mr. Zhongmu''s body... President Ranjing, it''s only you, isn''t it?"


    Uncle Maori followed and stared at the changed face of Yanjing Zhangwu: "it''s really only you. You are the first one to enter the secret room to eliminate the evidence that you didn''t have time to eliminate at that time, right?"


    "It''s just that there are traces of coffee overturning under the coffee cup plate. What kind of evidence is this? Do I need to hide it?"


    "Well..." Uncle Maori''s head was a little stuck. He couldn''t help looking at Conan, who was usually very clever. But Conan didn''t continue to interrupt. He just looked at the coffee stains on the carpet. This time, it''s not just a homicide, it''s impossible to commit a crime... "Officer Mu Mu," Gao Cheng''s voice suddenly pulled Conan''s mind back, "has that woman''s identity been confirmed?"“ Not yet, "sighed Mu Mu, referring to the woman who jumped off the building." she died on the spot. After her identity is confirmed, she will contact her family members... "" I think, "Gao Chengyu Guang noticed Ranai''s face and whispered," if there is no accident, I already know the identity of the dead. "“ Do you know? "“ What dead man? Has anyone been killed? " All the people on the scene follow Mu Mu and look at Gao Cheng. Only Ranjing Zhangwu lowers his head. Gao Cheng didn''t immediately mention the female staff, but said to Gao Mu: "officer Gao mu, can you confirm the situation of President Ranjing''s company first? It''s better to find the whereabouts of President Ranjing at 6:30 when the crime happened... "Gao Mu Leng, who was standing behind, ran out of the door subconsciously:" OK, I know... "Mu Mu''s thick eyebrows twisted together and asked:" I said, brother Chenghu, do you really know the identity of the dead? "“ It''s not just her identity... "Gao Cheng takes the cup that serves as a pen holder on the office coffee table and puts it on the dining table. Then he tells everyone his inference:" what President Ranjing wants to hide is actually the existence of another person besides the producer of Zhongmu... "" another person? "“ The reason why there is no coffee on the plate is that it is not a coffee plate. It should also be used to put cakes, right? It''s just that someone put two cakes on one plate... "Gao Cheng looked at the deeply lowered head of Ranjing Zhangwu and separated the cake from the plate on the table. Suddenly, the scene of two people using snacks appeared on the table“ Because of the limited time, President Ranjing had to pour the coffee from another coffee cup into the flower pot in the corner. The empty cup disguised as a pen holder, but the smell of coffee was still quite obvious... "No," Mu Mu Mu looked at the table and said strangely, "there is only one fork for eating cake... Is it hidden in the kitchen?"“ If you have time to hide in the kitchen, you can take the dishes and put the coffee cup in the sink, "Gao Cheng said, shaking his head." that fork is probably still on Mr. Ranjing now, isn''t it? "“ Because there''s no time... "Ranjing Zhangwu took out his fork from his arms slightly depressed:" Mr. Zhongmu''s body is right in front of me. If I don''t shout at once, the first one will be suspected... "" then, "Mumu said in a deep voice," Mr. Zhongmu was born by Ranjing first... "" yes... "Ranjing Zhangwu bowed his head and said," I''m always angry with him at work, So just like the police officer you said, I pretended to commit suicide in the secret room. When I left, I also noticed my coffee and cake on the table. I said I would clean it up before I left, but Mr. Zhongmu said that if there was an emergency, I would go first and let him clean it up. Just in case I came back to have a look, the result was... "" it''s a pity, Mr. dye well. " Gao Cheng suddenly interrupted, "you can''t be a prisoner."“ Why Seii''s eyes trembled“ Because until the moment when the producer of Zhongmu was killed after drinking poisoned coffee, the prisoner still stayed at the scene, and just received the news that someone saw you in the drugstore near your company at the time of the crime... "Gao Cheng took the record book from Gao mu, who came back, and looked directly at Yanjing Zhangwu and said," it''s the staff of your company, The shop assistant in the drugstore can also testify... "I..." Yanjing Zhangwu said with a dry smile, "I went to buy some medicine today. It was more than 5 o''clock. Did they make a mistake about the time..." "President Yanjing locked the French window," Gao Cheng interrupted sternly in a loud voice, "in order to avoid the police thinking of the car park jumping incident, right? Your female staff member jumped down from the balcony and died on the spot, just after killing the producer of Zhongmu! " His face changed completely. He opened his mouth and couldn''t speak. His tears gushed out and he fell to his knees with a thump“ No... no! Wuzi is innocent... It must be Zhongmu. It''s all Zhongmu producers... "
