Qin Daming, the head of the serious crime team of the criminal police detachment of H City, received an anonymous report letter, in which he said that the police had arrested the wrong person and that the murderer of Wang Xuefeng was not Liu Dongfang.

Although it was an anonymous letter, Qin Daming still didn't dare to be careless, and immediately reported to the captain He Mingyuan.

He Mingyuan has been busy and dizzy in the past few days, listened to Qin Daming's report, frowned and read the anonymous report letter, and slapped the table heavily, "Nonsense!" ”

Qin Daming said, "Captain, although this report letter has a beginning and no end and does not provide useful things, the whistleblower seems to know some inside information, otherwise he would not say it so surely." The whistleblower either has insufficient evidence, or is fearful, or ......"

"Where are so many or?" He Mingyuan interrupted Qin Daming, glared at him and asked, "Do you suspect that Wang Xuefeng's case has another hidden secret?" ”

"Yes, based on the fingerprints, bloodstains and Sun Xiaoyan's ambiguous testimony left at the scene, it is somewhat reluctant to conclude that Liu Dongfang is the murderer."

"If Liu Dongfang is not a murderer, is Sun Xiaoyan a murderer?"

"Although Sun Xiaoyan is not a murderer, she may not be involved."

"How?"

"I always suspected that Sun Xiaoyan was hiding the truth. According to Liu Dongfang's confession, he was invited to Sun Xiaoyan's house as a guest, and he didn't know that the house belonged to Wang Xuefeng, let alone that Wang Xuefeng would go there. Sun Xiaoyan said that Wang Xuefeng and Liu Dongfang had a confrontation due to love entanglements, and she wanted them to take a step back and get back together; At this moment, Sun Xiaoyan received a call from her father, saying that her mother was sick and admitted to the hospital, so she left in a hurry, not knowing what happened later......

"I know all of this! Whether it is the communication record or the on-site verification, it proves that Sun Xiaoyan is not lying, isn't this what your serious crime team has identified? Where is the suspicion? He Mingyuan was a little impatient.

"There are at least two suspicious points," Qin Daming continued to say according to his own train of thought no matter whether He Mingyuan was impatient or impatient, "First, the verification of our serious crime team can only prove that Sun Xiaoyan left the scene, but it cannot prove whether she left before or after the fact; Forensic identification also only provides an approximate time, and is not accurate to the minute, minute, and second. Second, Sun Xiaoyan said that when she left Room 1801, Wang Xuefeng and Liu Dongfang had already shaken hands and made peace. That in itself doesn't make sense. ”

"Go on." Obviously, He Mingyuan became interested in Qin Daming's analysis.

Qin Daming frowned, and said word by word, "I suspect that there is a fourth person in Room 1801!" ”

"The fourth person?" He Mingyuan was stunned.

"Yes!" Qin Daming firmed up his judgment: "The fourth one is the real murderer!" ”

He Mingyuan's eyes widened, he opened his mouth, and closed it again.

Qin Daming continued his reasoning: "This person is both a murderer and a behind-the-scenes manipulator. He should be very familiar with Wang Xuefeng and Liu Dongfang, and he has an extraordinary relationship with Sun Xiaoyan. This person has a hatred with Wang Xuefeng and Liu Dongfang for some reason, and it is possible for political and economic reasons; If my judgment is true, this person not only killed Wang Xuefeng, but also blamed Liu Dongfang, killing two birds with one stone, both insidious and sophisticated. ”

He Mingyuan is an old criminal policeman, so he naturally knows the intricacies of the case, but no matter how he listens, he feels that Qin Daming is too far away from the topic, and seems to be conceiving a detective reasoning novel.

"Qin Daming, can you be realistic? If you follow your deduction, there may be more than four people in room 1801, there will be a fifth, sixth, or even more! ”

"No!" Qin Daming was unmoved, and still insisted that the fourth person was the murderer of Wang Xuefeng.

"Sun Xiaoyan is young and beautiful, since she can make Wang Xuefeng and Liu Dongfang jealous and fight, she may not let other people take risks. Sun Xiaoyan works as a waitress in a high-end nightclub and has access to many celebrities, including powerful heavyweights; If someone regards Sun Xiaoyan as a confidante and tries to occupy the custody, he will naturally hate Wang Xuefeng and Liu Dongfang, who are clinging to Sun Xiaoyan, and will naturally do whatever it takes to get rid of these two. If that were the case, the tragedy that took place in Room 1801 was inevitable. ”

He Mingyuan said, "We can't rule out this possibility, but how do we do it?" Do you want to find a needle in a haystack to find the mysterious fourth person? ”

"There is no need to look for a needle in a haystack," Qin Daming said, "The murderer is by Sun Xiaoyan's side, as long as Sun Xiaoyan opens his mouth, it is easy to catch the murderer." ”

"Tell Sun Xiaoyan to speak?" When it comes to Sun Xiaoyan, He Mingyuan is angry. He has learned Sun Xiaoyan's difficulties many times. At a young age, there is a hard heart, whether it is soft, hard, coaxing, or scared, it doesn't work. If you ask her, you will say it as many times as you ask, neither one more word nor one less word. What can be done about this kind of goods that can't be pierced by water!

Qin Daming didn't know that Sun Xiaoyan was a difficult bone to gnaw! But he did not lose faith, and he had to take this mountain.

"Captain, in the past, we only stared at Liu Dongfang and Sun Xiaoyan, so we entered a dead end; If you change your strategy, start by screening the suspicious people around Sun Xiaoyan, and attack her unprepared, you may have unexpected gains. ”

He Mingyuan pondered for a long time and asked Qin Daming, "What are you going to do?" ”

"Immediately arrest Sun Xiaoyan and exert strong pressure to force her to tell the truth."

"Yes, but you must be in a sense of proportion, and you can't break the law and discipline."

"Understood!"

In the interrogation room of the criminal police team, Sun Xiaoyan, who has always been full of confidence, was a little frightened and overwhelmed. Although she is still performing her tried and tested tricks, her confidence is losing little by little, and her mood is becoming more and more flustered and heavy. She knew the two young policemen sitting in the front, the male policeman was named Qian Gang and the female policeman was Sun Lili.

"Sun Xiaoyan, do you know this person?" Qian Gang shook a photo in his hand and quickly put it down again.

The photo is not big, the time is short, and it is far away, which is difficult to see clearly under normal circumstances. But Sun Xiaoyan just saw it clearly! She recognized it at a glance as a photo of Sun Yunfeng of the Drunken Qingfeng Nightclub, and her whole body trembled, and her heart was pounding.

"I don't know." Sun Xiaoyan shook her head.

"She lied!" Sun Xiaoyan's fleeting changes did not escape the eagle-like eyes of He Mingyuan and Qin Daming in the monitoring room next door. He Mingyuan immediately issued an order to Qian Gang, "Go straight to the point and catch her off guard!" ”

Qian Gang understood, slapped the table hard, and said sharply, "Lie!" He whispered to Sun Lili beside him, "Show her the photo." ”

Sun Lili walked over and put the photo in front of Sun Xiaoyan's eyes, "Look at it!" You are legally responsible for every word you say! ”

Before this, Sun Xiaoyan knew that the police would not give up, so she made full preparations. She insisted on the established facts, neither saying one more word nor one more word, so as not to change and respond to all changes. However, unexpectedly, Qian Gang unexpectedly showed a photo of Sun Yunfeng, which made her confused for a while, and blurted out the words "I don't know". In her subconscious, she must protect Sun Yunfeng and not let the police suspect Sun Yunfeng. At the moment when Qian just showed Sun Yunfeng's photo, she made an irreparable mistake. Sun Yunfeng is the boss of the Drunken Qingfeng Nightclub, and only fools and people with evil intentions will say that they don't know him. Therefore, when Sun Lili put the photo in front of her, she pretended to look at it for a long time, and finally pretended to be surprised and said, "Ah! This is a photo of our Mr. Sun! Then he added, "I didn't see it clearly." ”

"Sun Xiaoyan, I hope you don't pretend to be confused!" Qian Gang lowered his face, and his words were quite stern: "The police have detected that there were four people in Room 1801 on the day of Wang Xuefeng's accident through the high-tech device nicknamed 'Ghost Shadow' just equipped; if you don't want to be charged, if you don't want to bear the murder for others, just tell the fourth person honestly." I can responsibly tell you that the police have obtained important clues through the 'ghost', and now I let you say that it is a chance to make meritorious atonements. If you can actively cooperate and truthfully provide information to the police, you can not be held criminally responsible. Otherwise, you have covered up the murderer many times, and you have already violated the criminal law, and you will be sentenced to at least three years and five years. Whether to continue to cover up or turn back in time, but think clearly! ”

Although Sun Xiaoyan is well-informed, she can't withstand Qian Gang's bombardment. Thinking about the terrible consequences, I began to be timid. Although she took Sun Yunfeng's money, although she did some quite outrageous things for Sun Yunfeng, used the "beauty trick" to subdue Wang Xuefeng and Liu Dongfang successively, and lured him to fight jealously, but that's all, she didn't break the law. It's just that I never expected that Sun Yunfeng turned out to be a ruthless person, who brutally stabbed Wang Xuefeng to death, and framed Liu Dongfang by any means, he was simply a pervert! Fortunately, he kept a hand and secretly photographed the scene of Sun Yunfeng's murder, in case he had to prove his innocence as a last resort. Now listening to Qian Gang's words, the defense line she had worked so hard to build collapsed in an instant
