After meeting with gongchang, Gao Cheng gets the chance to meet Xuantian.


    I don''t know whether it''s true or not. It seems that the bow commander highly praises his past resume, and I don''t know why a fire uncle attaches so much importance to the cases of other groups.


    Investigation room, Xuantian a person sitting down, looks like a pair of give up treatment depressed appearance.


    A policeman stood outside in distress and reported to the bow leader who brought Gao Cheng, "he still can''t say why, but insists that the other one set the fire himself."


    "Well."


    The factory nodded to signal the police to leave, and looked heavily across the glass at the exhausted Xuantian in the interrogation room.


    "If we can''t find any other clues, we''ll have to send him for trial in the end..."


    After a pause, Gong sighed and turned to Gao Cheng: "detective Chenghu, do you know why I believe him?"


    Gao Cheng is also curious: "is it because of Xuantian''s Fireman father?"


    The bow leader neither denied nor nodded, but recalled, "when I first investigated Xuantian, I once called him to the park and talked with him once. After 30 minutes, the guy didn''t say anything. He just sat on the bench with a sad face, just like now


    "But when I left, I looked at him from a distance, but I saw him leave the bench and look for something in the grass around him. After a while, it began to rain, and he gave up. When I saw him at ease, I understood that he was looking for the cigarette end I had smoked, which was the cause of the fire that killed his father..."


    Bow long silently put out the hand of cigarettes, eyes sincerely.


    "I can''t imagine that a guy like him would set fire to someone else''s house, and I don''t want to think like that... Detective Chenghu, I''ve investigated your case. Since I became famous, the detection rate has been 100%. No matter how complicated and difficult the case is, I can find out the truth. Can you help Xuantian this time?"


    Gao Cheng looks at the silent Xuantian in the interrogation room, and has a deeper understanding of this cowardly uncle.


    I''m afraid that his father''s death became Xuantian''s heart knot, so he was caught by the real murderer and used his weakness. In this way, the suspects, whether they are psychiatrists, feng shui masters or diviners, may manipulate Xuantian spiritually.


    "Let me talk to him first."


    Gao Cheng nods and walks into the interrogation room. Inside, Xuantian thinks it''s the interrogator again. He looks up and finds that it''s Gao Cheng. He can''t help looking surprised.


    "Detective Chenghu?"


    "I believe you are not the real murderer," Gao Cheng stood in front of Xuantian with a smile, "do you need me to prove your innocence? There is no commission fee. "


    ……


    Lishan Town, Xuantian family.


    When Gao Cheng arrived at the door in the police car of the bow commander, uncle Maori also drove over from the other side. When he saw Gao Cheng, the service department immediately said hello with a smile.


    "How''s it going? Chenghu, let''s find out the way to ignite the prisoner first? "


    "I''ve heard officer Gong Chang say," Gao Cheng gave a glance at PA SE''s service department. "So, how did you make an alibi?"


    The Ministry of clothing did not continue to be complacent, and his eyes were bright. He said, "we have checked the scene again. There were pieces of white woven light bulb on the fire site, and there were brown burnt marks and black round marks on it. There were ashes left after burning paper towel everywhere. The prisoner should wrap paper towel on the 100W light bulb and insert matches. Once the surface temperature of the light bulb is enough, the matches will be automatically lit


    "The surface temperature of a 100W light bulb can reach 218 degrees. It''s easy to light a match. The prisoner must have done something on the light bulb in the warehouse in advance, and then sprinkled oil on the floor. When the red horse whose base has been torn off is placed by the window, the ignition time can be adjusted by the amount of paper towel wrapped around the light bulb..."


    The Ministry of clothing looked at the Xuantian family and said with a smile: "this is the automatic ignition device for prisoners. The most obvious evidence is that there is a white light in front of the red horse shadow printed on the curtain next door! The next step is to find out how the prisoners manipulated Xuantian and the final evidence... "


    "So it is," said Gong Changsi cableway. "According to your opinion, it seems that it can ignite automatically, but the marks on the light bulb may also be formed by accident during the fire. Moreover, if this device is used, aren''t all three people possible?"


    Gao Cheng took out the key to open the door of Xuantian''s house: "anyway, check it first..."


    "Chenghu, the key you brought?"


    "Mr. Xuantian lent it to me, and I took his commission."


    Gao Cheng pushes the door open and takes the lead in entering the porch. At the first glance, he is attracted by the shoe prints in the corridor. He takes out the shoes in the shoe cabinet of the porch and tries them. The shoe prints of Xuantian are about the same size.


    "Xuantian lives in such a big house alone..."


    "Well, after his father died, he lived with his mother. I heard that his mother died last year."


    Bow long put on slipper in porch, frown to see shoe mark.


    "Are these shoe prints from Xuantian?"


    "As I thought," Uncle Maori followed Conan to take out socks full of mud and shirts with charred marks from the garbage can beside him, "gongchang, Xuantian said that when somnambulism was serious, there was another one who set fire himself. His words may be true..."


    "It''s too early to say that now," Gao Cheng stood up and said, "maybe this is also the hand and foot of the real murderer..." now the most important alibi has been explained, that is, automatic delay ignition. In addition, he has asked about the motives of several suspects. Feng shui master once threatened me with a secret video by the wife of the dead Liangzi. Quan Teng, a female diviner, was able to get a large amount of inheritance from her father after Liangzi died. The will is to leave the inheritance to the people who inherit Zhujiao''s surname, So originally, only Liangzi who recruited her husband could get the inheritance... As for her husband, Zhu jiaoming, the psychiatrist, although he would not get the inheritance because of his wife''s death, he did not have no motive. It''s said that zhujiaoming has been trying to demolish the house to build his own hospital, but Liangzi, who owns the house, doesn''t agree. In addition, about Liangzi''s affair, zhujiaoming probably knows... The real culprit should be one of the three. That''s right. Gao Cheng''s fingers and eyebrows light, before and after the details flash in my mind. There are also a few strange doubts. At the beginning, Mrs. Liangzi entrusted Nanchuan to investigate suspicious people. When Uncle replaced Nanchuan to Zhujiao''s house, Mrs. Liangzi suddenly changed her tune. In addition, the little cushion that Mrs. Liangzi held tightly in her hand before she died seemed to belong to a diviner... This thing does not mean that the murderer is a diviner. Wait a minute... Mrs. Liangzi didn''t see the automatic ignition device installed by the murderer. Did she know who the arsonist was in advance, so she suddenly changed her tongue“ "Hello, Chenghu," cried the service department, looking over the shoe cabinet for a while, "come here quickly!"“ "Ah?" Conan followed Gao Cheng suspiciously to the service department“ What''s the problem? "“ You see, this is the receipt of telephone fee on the shoe cabinet. It''s not strange that it costs 30000 yuan a month? Xuantian doesn''t look like he''s going to call a lot. "“ "Well," Conan nodded, "Xiao Lan often talks to Yuan Zi on the phone, but the phone bill is not so much..." "so," the service department recalled, touching his chin, "the same as ye Na, who often calls for a long time. Why do women like to call so much?"
