After work, Si qiongzhi didn''t go home.


    Tonight is not her night shift, but in the afternoon, she chatted with the night shift doctor and said that she had something to do the day after tomorrow and wanted to change. The doctor on duty said, "that''s a coincidence. My fiancee was angry yesterday. I''m going to invite her to dinner to coax. Dr. Si, I can change with you."


    So Si qiongzhi got the opportunity to be on duty at night.


    She waited until the whole department was quiet. It was about early in the morning that she sneaked into Peicheng''s office.


    She took a military flashlight from her father''s drawer.


    Turn on the flashlight and Si qiongzhi looks around.


    Pei Cheng''s office is very simple. There is a wardrobe, an office, a sofa and a coffee table.


    Si qiongzhi rummaged through his wardrobe.


    She looked carefully in his wardrobe for a long time, and suddenly saw a white shirt folded by Peicheng at the bottom of the wardrobe.


    Si qiongzhi pulled out his shirt and saw blood stains on it.


    She suddenly lost her footing and her feet softened.


    "Kill Hu Qiaoer first, then blame Peijie, and kill with a knife except Peijie..." Si qiongzhi thought tremblingly, "what kind of devil is Peicheng?"


    She rolled up her blood clothes, stumbled back to her office and called home.


    There is an adjutant on duty at home. After receiving the phone, he immediately came to pick up Si qiongzhi.


    Si qiongzhi''s hands were shaking all the time, and he looked at the corridor from time to time for fear that some evil ghost would haunt her.


    She was stunned, but a cold sweat came from her forehead.


    Why would she doubt Pei Cheng?


    Since Hu Qiaoer''s death, her speculation has lingered.


    Even if Pei Cheng speaks for her and believes in her, why does she have to doubt him? Did she have such a deep distrust of this man?


    Besides, what''s the use of getting a bloody shirt?


    It''s not certain that he killed Hu Qiaoer.


    "If only medicine could develop for a few more years and determine who it belongs to through blood." Si qiongzhi thought.


    Trembling, she waited for her two aides to come.


    The adjutant accompanied her on duty until five o''clock in the morning, when she had to leave work, she didn''t go home with the adjutants.


    She gave the blood coat to her sister-in-law.


    When Gu Qingzhou saw the blood clothes, he said cautiously: "Pei Cheng is a doctor. There may be blood everywhere in the hospital. Moreover, there are not many blood stains on the clothes, and it doesn''t look like they were splashed all over his body after killing."


    Si qiongzhi also stretched out his head to have a look.


    Almost all the blood on the shirt is on the back, not on the front.


    She paused: "I..."


    At this time, the telephone in Gu Qingzhou''s room rang. Niu huaigu of the police station called her: "chief officer, we found the murder weapon and the murderer."


    "Hu qiao''er case?" Gu Qingzhou asked.


    "Yes, come and have a look." Niuhuai ancient road.


    Si qiongzhi looked at it with bright eyes and wanted to know who the murderer was. Gu Qingzhou asked, "who has the murder weapon?"


    "Sun Jin." Niu Huai said, "you let us pay close attention to Sun Jin and finally make progress."


    He is very happy there.


    Gu Qingzhou was afraid that he would end the case indiscriminately, so he said, "wait for me to have a look, and then make a report."


    After hanging up, Si qiongzhi hurriedly asked, "what''s going on?"


    "They caught Sun Jin and the murder weapon was with her." Gu Qingzhou road.


    Si qiongzhi was struck by lightning.


    She sat down stunned and mixed feelings for a moment.


    "Isn''t Pei Cheng the murderer?" She mumbled, "if it wasn''t for him, what would I be doing?"


    She couldn''t stand up for a long time.


    Gu Qingzhou patted her on the shoulder and turned to the security department.


    Sun Jin in the interrogation room was haggard, with messy hair. She no longer had the self-restraint of a lady. She kept shouting, "if it''s not me, how can I kill?"


    Gu Qingzhou asked the cow waiting for her, "what''s going on?"


    Niu huaigu said, "we''ve been sending people to watch her. We found that she sneaked out with her suitcase at night and went directly to the dock.


    When she threw her suitcase into the sea, we felt it was inappropriate. We immediately pressed her down and fished it up. In this suitcase, there are some clothes and a bloody dagger. "


    Gu Qingzhou was stunned.


    "The medical police said that the murderer hated Hu Qiaoer so much that he put on such a heavy hand. And he was taller than Hu Qiaoer." Gu Qingzhou said, "Sun Jin doesn''t match the two?"


    "There were no witnesses at that time. Who knows if she beat Hu Qiaoer to his knees before stabbing her? Besides, women have great power in case of urgency." Niuhuai ancient road.


    Niu huaigu finally said: "she had an affair with Peijie, which she admitted. She took a fancy to Peijie and wanted to kill his wife instead, but she helped Peijie when he was identified as the murderer.


    At that time, the Pei family and Peijie will thank her. Won''t she be able to marry Peijie after a year or two? The sun family is famous for their love of drilling camp. I think all this makes sense. "


    Gu Qingzhou was silent.


    Niu huaigu said, "chief officer, do you think you can close the case?"


    Gu Qingzhou looked at him in surprise: "how to close the case?"


    "Sun Jin killed Hu qiao''er, and the murder weapon was found. There is no doubt about this case." Niuhuai ancient road.


    "What about Pei Jie?"


    "That''s an accident." Niu huaigu said, "the thief was nervous when stealing the car. He couldn''t distinguish between brake and throttle. It has nothing to do with this case."


    Gu Qingzhou frowned.


    She said, "I want to talk to Sun Jin."


    Niu huaigu is a little afraid of complications. He wants to close the case quickly and give an explanation to others and the Pei family to show them the speed of the police station.


    "Director, don''t you agree with my judgment?" Niu huaigu asked.


    Gu Qingzhou said, "I disagree."


    An ox is nostalgic.


    "I want to talk to Sun Jin." Gu Qingzhou said, "when I finish talking, I''ll tell you the result."


    Niu huaigu had no choice but to let Gu Qingzhou in.


    Sun Jin''s eyes were swollen with tears, and her face was gray, anxious and frightened: "Sir, you want to avenge me! I''m wronged. I''m really wronged. I didn''t kill anyone."


    Gu Qingzhou picked up the copy on the desk.


    She looked and asked Sun Jin, "the police have investigated. You bought this box yourself. The murder weapon is in your box. What can you argue about?"


    "No, no, listen to me!" Sun Jin hurriedly said, "this box is not mine, but Pei Jie''s."


    She was afraid that Gu Qingzhou didn''t believe it. Before Gu Qingzhou spoke, her voice became louder and louder: "on the morning of Pei Jie''s death, he said he would go out and ask me to go with him.


    I knew he had a lot of money with him, so I planned to use the same box and replace him. Every time I go out with others, I will bring something back. This is my habit. "


    She is also a habitual thief.


    But she stole those men.


    "We made an appointment at the dock first, but he forgot to get his passport and temporarily drove back. I waited for a long time and saw that he didn''t come, so I took his box and left my box on the ship.


    If he had to look for it, he would think that the box he found was switched by the people on board. I was going to change when I returned. Unexpectedly, when I took it home, I found a bloody dagger in this box. I was afraid that I could not explain clearly, and Peijie had a car accident, so I wanted to throw it away. "
