There is rarely such a tense atmosphere in the office of the director of the Nanshan District Criminal Police Brigade as there is today, and Hao Liye, the director of the bureau, who has always been sensitive, smelled something wrong in this case, but he couldn't say what was wrong. The order has been issued above, and the case of Zhou Xi's naked death at home requires him to solve it as soon as possible. Hao Liye pondered, presumably Christmas was approaching day by day, and he didn't want a murderer at large to wander in the crowd and cause unnecessary worries to the citizens who wanted to travel and play, so he urged it so tightly.

But in a blink of an eye, Zhang Xian's detention time was approaching soon, but Bi Guofeng did not come to report the progress of the case to Hao Liye. Hao Liye looked at the clock on the wall anxiously, picked up and put down the mobile phone in his hand, and picked it up again after putting it down, unable to make a decision in his heart.

Just when Hao Liye was worried, the door of his office was suddenly pushed open, and Bi Guofeng rushed in with his mobile phone. Hao Liye stood up and hurriedly asked, "How is it, has there been progress?" ”

"Quickly extend Zhang Xian's detention time!"

"What's the situation?"

I saw Bi Guofeng use his mobile phone to play the surveillance video copied from the pharmacy and hold it up in front of Hao Liye, and shouted loudly: "Look at him, does it look like him?" Like not! ”

Hao Liye stared at him for a while, and said with some uncertainty: "Tsk...... You have to ask me...... It's hard for me to say. ”

"Don't talk about this yet, you can take your time after you extend the detention time."

"That's all you got this footage?"

"Yes...... How? Bi Guofeng frowned and looked at Hao Liye.

"You sit down first, this is not easy to do......" Hao Liye tried to appease Bi Guofeng, the video cannot be used as evidence in court under normal circumstances, not to mention that the people in this video can't even see their faces clearly.

"There's no time to sit now!" Where could Bi Guofeng listen, he immediately became impatient when he saw Hao Liye playing sloppy with him. This is the only clue that has been investigated for several days, and if Zhang Xian is released at this time, it means that all the previous efforts will be wasted.

Hao Liye shrugged his shoulders: "I have seen the autopsy, and the diphenhydramine found in the victim's stomach is not a poison, this is just an ordinary antiemetic, it is not even a prescription drug, everyone has the right to buy it." Zhou Xi was strangled to death, and there was no connection with medicine at all. You stare at the person who buys the medicine, which is also ......"

"No, of course there is!" Bi Guofeng retorted, "The effect of this medicine is to stop vomiting, but we investigated Zhou Xi's work arrangement, and she has no intention of going far away, or taking a long-distance bus, plane, or ship." Moreover, we searched carefully in the victim's home, and found no other diphenhydramine, not even the outer packaging. So I have reason to suspect that this medicine does not belong to Zhou Xi, but comes from someone else. ”

Hao Liye was stunned for a moment: "Why do you think that this medicine does not belong to the victim, but to someone else?" ”

"Didn't we have the surveillance footage? Although this monitoring is not clear, the person who bought the medicine inside is indeed a man. ”

"Have you checked with the pharmacy clerk?" Hao Liye squinted his eyes and looked at the person on the surveillance video carefully, judging from his figure, he was indeed a man.

Bi Guofeng said: "It has been confirmed, and he said that it must be a man." ”

"You wait...... There seems to be something wrong with what you said. ”

"What's wrong again?"

"How do you prove that the diphenhydramine sold in pharmacy No. 17 is the same as the diphenhydramine that Zhou Xi ate on the 18th? If the diphenhydramine she ate on the 18th was bought by Zhou Xi before......"

Bi Guofeng was stunned for a moment, and then explained: "No. Only this pharmacy in Changlu City sold a box of diphenhydramine on the 17th in December. On top of that, Zhang Xian's home is only 15 minutes away from this pharmacy. ”

"15 minutes away...... The judge doesn't want to listen to this kind of thing," Hao Liye pondered for a moment and then asked, "Have you checked this line of online shopping that week?" Did she ever find out that she bought this drug online? ”

Bi Guofeng shook his head: "Not only online shopping, but also mail order, TV shopping and telephone shopping, I have checked, and there is no information about buying diphenhydramine." ”

"You mean, the diphenhydramine that Zhou Xi ate can only be the box sold by this pharmacy on December 17?" Hao Liye found that Bi Guofeng's speculation had his own reason, but he vaguely felt that there was something missing.

After thinking for a minute, Hao Liye said: "Have you inquired about Zhou Xi's social circle?" Is there anyone else to doubt? If it was his friend who bought it for her, or Zhou Xi himself asked a friend to buy it. These people are suspicious ......"

"Those so-called friends of hers......" Bi Guofeng sighed, "It's really hard to say, it's complicated anyway." But on the issue of the person who buys the medicine, I will not let go, I think this person is Zhang Xian. ”

"Don't rush to conclusions, if you have to say that Zhang Xian is okay, then you have to come up with evidence. If there is no evidence, let it be excused. You know that the clarity of this surveillance video is so poor that it cannot be used as evidence in court. ”

"That's why I'll let you show the detention time first, and I'll check it carefully." Bi Guofeng grabbed his hair fiercely, "This Zhang Xian said that after he arrived at Zhou Xi's house on the 17th, Zhou Xi was already dead. But judging from the degree of digestion of diphenhydramine in Zhou Xi's stomach, she ate diphenhydramine shortly before she was killed. In other words, before Zhou Xi was killed on December 18, she met the person who gave her medicine. ”

"But even if someone gives her medicine, it doesn't necessarily prove that the person who delivered the medicine is the murderer. Besides, the medicine was sold on the 17th, and the medicine in Zhou Xi's stomach was only taken on the evening of the 18th, and there was such a long time in between. Hao Liye said.

Bi Guofeng was immediately speechless when Hao Liye said this, and it is true that what he said was reasonable. After selling the medicine in the pharmacy on December 17, Zhou Xi only took it on the night of the 18th, which lasted for more than 30 hours, and Zhou Xi may have obtained the medicine from others at any time during this period, not necessarily just getting the medicine before being killed. In other words, the person who gave her the medicine is most likely not the same person as the person who killed her.

Hao Liye saw that Bi Guofeng didn't speak, and knew that he also understood the loopholes in his reasoning, so he turned the topic to another question: "Actually, there is no need for us to stare at Zhang Xian and ......."

"However, if you think about it, if the person who delivered the medicine and the person who killed Zhou Xi are not the same person. So why did the rest of diphenhydramine disappear from the scene? The same goes for the chocolates found in Zhou's stomach. If it weren't for diphenhydramine and chocolate that could prove the identity of the murderer, what reason did the killer have to take these things away from the scene? ”

"You mean diphenhydramine and chocolate have the killer's fingerprints on them, so he had to take these things away, right?"

"Isn't it?"

"But if you say this, Zhang Xian is even less likely to be a murderer. If he was the murderer, since he still had the ability to clean up the physical evidence, how could he not flee the scene after cleaning up, but fell asleep on the ground? ”

"Maybe he'll come back and pretend to be drunk after cleaning up...... Or ......" Bi Guofeng said, his voice lowered. He himself knew that these claims were too far-fetched.

Hao Liye sighed when he saw this: "Let's let Zhang Xian go first, didn't you just say that you have investigated all those friends of Zhou Xi?" None of them are suspicious? ”

Hao Liye didn't say that it was okay, but Bi Guofeng felt that his head was big: "I captured a woman, but it's a pity that it's a bit complicated......"

"Don't say half of it, what's complicated?"

This woman's name is Mu An, and she is a good friend of Zhou Xi, but she has an ambiguous relationship with Zhang Xian. It is said to be Zhang Xian's ex-girlfriend, and Zhou Xi only got along with Zhang Xian after they broke up. In terms of the motive for the killing, I think this woman is even more suspicious than Zhang Xian. But given her performance in the interrogation room, my gut tells me that she wasn't very involved in the case. ”

Hearing this, Hao Liye felt that Bi Guofeng's investigation seemed to have made a lot of progress, but how could he say that it was very complicated? Hao Liye asked strangely: "Has this Mu An's alibi been checked?" ”

"Checked, there's no problem. At the time of Zhou Xi's murder, she was doing beauty treatment with two other friends. However, since she has a motive to kill Zhou Xi, we can't rule out her suspicion now. ”

"You said you had brought people back to the bureau, but what about the people now?"

"It's in the interrogation room downstairs."

"Have you asked?"

"I asked, but I didn't get much. This person feels quite simple, and he can't see that he has the courage to kill. “”

Hao Liye rubbed his hands: "It seems that this case is really difficult to handle, what about Zhou Xi's other friends?" It is impossible to have an alibi on the night of the 18th, right? ”

"Today, I also went to meet Qian Zhiguo, Zhou Xi's costume artist, and Tong Yao, the leader who arranged work. However, none of them are as suspicious as Zhang Xian. ”

"You analyze it for me first."

"Zhou Xi was only wearing underwear when he was killed, but other clothes were missing. I deduced that the killer had taken her clothes, but I couldn't guess why. According to Professor Liu's analysis, the murderer may have been a person with a certain degree of psychopathology, and the purpose of taking the clothes was to obtain 'war spoils'. Although in a later autopsy, he found a kiss mark on Zhou Xi's neck caused after his death, I don't think this is enough to support that the murderer has a mental disability. Personally, I think that the murderer is likely to be a thoughtful criminal IQ who may have deliberately mimicked the perverted murderers in the textbooks. ”

"You mean, the killer may have deliberately done something seemingly illogical to confuse us police?" Hao Liye agreed with Bi Guofeng's statement.

"There is a real possibility. When I went to meet Qian Zhiguo with Chang Zhi, I learned from him that Zhou Xi took a dress from him to wear at the Christmas show. But we were at Zhou Xi's house, but we didn't find the dress Qian Zhiguo said. From this, I guess this dress should be the one that was taken by the murderer. ”

"So what is your judgment of Qian Zhiguo?"

"There is a suspicion, but there is not enough evidence to support it. Because there are only a few people related to that dress, and Qian Zhiguo is one of them. He is a person who has a good reason to let Zhou Xi take the initiative to open the door for him. ”

"You mean for the dress?"

"Yes, the dress. I had imagined that on the night of December 18th, Qian Zhiguo would come to Zhou Xi's house and ask Zhou Xi to open the door and let him enter 1302 on the grounds that he had a problem with his dress or something similar. At this time, Qian Zhiguo may not have the intention to kill. But the purpose of his coming may be because he has a lust for Zhou Xi. When I met with Zhou Xi, I asked her for sex, but Zhou Xi sternly refused. In the end, Qian Zhiguo, who was annoyed and angry, killed Zhou Xi. ”

But what reason did he have to take the gown? If Qian Zhihao is the murderer, then wouldn't he have three hundred taels of silver here when he took the dress? As you just said, there are only a few people related to this dress, and Qian Zhiguo is undoubtedly the most suspicious person among them. ”

"Actually, I think so, Qian Zhiguo said that he had handed over the dress to Zhou Xi on the 17th, but except for himself and Zhou Xi, no one knows when the specific time is."

"You mean, Qian Zhiguo is lying?"

"I have thought that Qian Zhiguo probably went to Zhou Xi's house on the night of the 18th, just to give this dress. By mistake, after killing Zhou Xi. In order to erase the fact that he had been to Jinjing Garden, Qian Zhiguo decided to take away Zhou Xi's dress. ”

"Your conjecture is a bit far-fetched, even if that dress is left on the scene, I don't think it will make any substantial difference to the case. If Qian Zhiguo insisted that he handed over the dress to Zhou Xi on the 17th, we couldn't help him. What do you think? ”

"So I said he had some suspicions, but the evidence was not enough to support them." Bi Guofeng sighed.

"Alas, this case doesn't seem to be simple."

"yes, it's not easy......"

Hao Liye pinched between his eyes, feeling that one head was two big. Bi Guofeng's strength to drill the horns of the bull was also experienced when he was a criminal police officer on the front line more than ten years ago. thought: If Bi Guofeng wants to dwell on this clue any longer, there will be no result, it is better to let him break his mind now.

"Guofeng, the evidence is not enough to prosecute Zhang Xian now, since the detention time has come, let's put it back first. If there are new clues, it's not too late for us to get them back. After speaking, Hao Liye picked up the microphone of the landline and dialed the phone of the detention center downstairs.

"What does it mean that the evidence is not enough, he obviously ......" Bi Guofeng was so anxious that he slapped the table.

Hao Liye ignored Bi Guofeng's words, picked up the phone at hand, and prepared to ask the people below to let him go. Seeing this, Bi Guofeng hurriedly grabbed Hao Liye's hand and said, "In this way, let's each give way, Zhang Xian can be released today, but don't inform his family, my subordinates will send him home, what do you think." ”

Hao Liye was confused, and it was still not in accordance with the regulations. But after thinking about it, he couldn't find where Bi Guofeng could make trouble, so he had to take a step and said: "That's okay, but you have to promise me that Zhang Xian must return home safely." Don't ...... people halfway."

"Tsk, what do you think of me, I'm a policeman anyway......"

"You still know that you are a policeman, don't ...... if you are a policeman" Hao Liye sighed and said, "Forget it, don't talk about it, you can arrange it." ”

Bi Guofeng was relieved when he got the promise, and he hurriedly made a call to Chang Zhi: "Hey, you go and release Zhang Xian and send him home in person, the director has already let go here, you just have to do it." ”

Then, Bi Guofeng left the director's office and ran to the item management room, and said to the administrator Xiao You: "Where is Zhang Xian's things?" ”

"What's wrong here?"

"Give it to me, give it to me."

Xiao You was a little confused by the second monk: "Zhang Xian is going to be released?" ”

"Isn't it, otherwise why would I ask you to take his things?"

"Then you want him to sign, you don't take it properly, right?"

"Tsk, why are you so brainless, where are you signing? Let me see. ”

Xiao You didn't know what medicine Bi Guofeng was selling in the gourd, but he didn't have any suspicions, so he found the watch and handed it to Bi Guofeng.

Who knows, Bi Guofeng didn't say a word, took out a pen from his arms and signed Zhang Xian's name on the form.

"Huh...... You! Xiao You didn't even have time to reach out to grab the form, Bi Guofeng had already succeeded.

"Alright, now you can give me something. Don't tell me you have to ask Zhang Xian to sign it again. ”

Xiao You is angry and doesn't fight anywhere, but now that the wood is complete, there is no room for recovery. He took out Zhang Xian's bag of things and handed it to Bi Guofeng and said, "Don't take the sheep by the hand, otherwise I won't be able to eat and walk around." ”

Bi Guofeng grinned and ran out of the office building quickly with the bag of goods. It wasn't until he walked into the yard that Bi Guofeng opened the bag this time, took out Zhang Xian's mobile phone and stuffed it into his pocket.

At this time, Zhang Xian and Chang Zhi happened to come out with Zhang Xian, Bi Guofeng stuffed the bag into Chang Zhi's hand, and then whispered in his ear: "Drive as slowly as possible on the road, don't let him call, and don't let him get out of the car, remember." ”

Zhang Xian on the side didn't know what the two were doing, so he sat in Chang Zhi's car by himself. For some reason, there was still a smug look on his face. After Bi Guofeng finished explaining, he glanced at Zhang Xian fiercely, and the man captured in the surveillance camera in his heart had at least an 80% chance that it was Zhang Xian. Although, that may not prove that Zhang Xian is the murderer. But somehow, Bi Guofeng is very unhappy with Zhang Xian.

After Zhang Xian and Chang Zhi left, Bi Guofeng walked towards his Santana. But at this time, Hao Li suddenly walked over. According to Bi Guofeng's usual temper, no matter what Hao Liye says next, he is ready to play the scoundrel to the end. The case he took over this time was not simple, and the murderer was obviously a man with brains. And Liu Lujin also analyzed that this person is very likely to be a perverted murderer. In the face of such a tricky opponent, he is not willing to waste any time on the rules or stance of the game.

So as soon as Bi Guofeng saw Hao Liye, his face immediately turned up. Hao Liye is used to seeing all kinds of people, but he is still afraid of seeing Bi Guofeng's appearance. In his eyes, Bi Guofeng is a person who can do things and do good things. But Bi Guofeng's temper is too irritable and too impulsive, and he is not the kind of person who can climb up. If he is left on the front line and let him kill the enemy, it will be over in less than ten minutes. In fact, there is no difference between this public security bureau and the front line, and if you want to survive here, you must know when to be a hero and when to be a turtle with a shrunken head. Sometimes it may not be useful to work the battlefield, but the most important thing is to think clearly about your situation and make accurate judgments. But the only thing Bi Guofeng lacks is the quality of judging the situation.

The first thing Hao Liye said when he saw Bi Guofeng was: "Hard work, smoke a cigarette?" As he spoke, he took out a pack of Lianhe brand cigarettes in his early 40s from his pocket.

Bi Guofeng is not polite, he usually only smokes cheap Shuanglu cigarettes, and now he has good cigarettes to smoke, what reason is there to refuse? He reached out and took a cigarette from Hao Liye's cigarette case, put it in his mouth, and then reached for the cigarette case again.

Hao Liye thought that Bi Guofeng wanted to take the lighter, so he reached out and touched it in his pocket. Unexpectedly, Bi Guofeng took another cigarette from his cigarette case, and this time he put the cigarette on his ear. Then he took out a lighter from his pocket and lit the cigarette in his mouth.

Hao Liye smiled bitterly, and also took a cigarette and lit it. The two stood together and "clicked" for a while, but neither spoke. In the end, Hao Liye couldn't help it, he said: "Ah Feng, this case has been urging me tightly. ”

"Really? My dad asked me to go on a blind date. Bi Guofeng took a deep breath of cigarette, his eyes narrowed.

Bi Guofeng's answer to the horse's mouth made Hao Liye feel funny, but he didn't dare to laugh. He patted Bi Guofeng on the shoulder and said, "Do you know the Christmas Film Festival? ”

"I don't watch movies, and movies aren't good now."

"Really? I don't know the tastes of you young people, but I think that Sun Qili is very beautiful now, and that figure is ...... Gee. ”

Hao Liye thought that when it came to these things that any man would smile, Bi Guofeng would be a little relaxed. But Bi Guofeng still had a blue face when he heard this, and he looked like he didn't eat oil and salt.

Bi Guofeng shook the ash of his cigarette and said, "I like Ingrid Bergman." ”

"Hard pigeon, what's the pot?" Hao Liye didn't understand what Bi Guofeng was talking about, thinking he was talking about the name of a dish.

"You don't understand, so don't ask."

"Uh-oh." Hao Liye nodded, but he didn't think it was wrong.

Bi Guofeng and Hao Liye quickly finished smoking a cigarette, but there was no progress in their conversation. Hao Liye was a little anxious, he had never been caught in his speech, but when he met Bi Guofeng, his tongue was out of order. He was afraid that Bi Guofeng would be in a hurry, so he didn't do anything, and he couldn't find another capable person to take his place at this time.

A thorn like Bi Guofeng, it is not easy for him to use his identity as the director of the bureau to press him. So I had to say with a smiling face: "Come on, I don't have anything to do, it's just that the Christmas Film Festival is being held recently, and we still have to worry more about security." Then he took out the half pack of Lianhe cigarettes in his pocket and stuffed them into Bi Guofeng's hand, and said: "I can't get used to smoking this cigarette, so if you like it, I'll give it to you." ”

At this time, the expression on Bi Guofeng's face finally relaxed, he took the pack of cigarettes and said, "Then thank you, I won't delay you, go first." With that, Guofeng got into his Santana and left the precinct.

On the way, he took out a bag of Lianhe cigarettes and put them in the lattice in front of the passenger seat. Although Hao Liye didn't say anything to him, Bi Guofeng's heart was bright. It is not so much that Zhou Xi's case has attracted the attention of the above because of its particularity, but that it is just at this juncture of the Christmas Film Festival, and the above has to make some statements in front of the masses.

Bi Guofeng knew how to deal with such pressure, and the first thing he had to do was to call a few of his subordinates and ask them to split into two groups. One group went to keep an eye on Zhang Xian, and the other group went to the vicinity of Jinjing Garden, where Zhou Xi was killed, for intensive visits. Although these two tasks have hardly helped to solve the case, they can at least give the appearance that the police are working hard. In this way, you can warn the murderer not to have the idea of continuing to commit crimes, and secondly, to block the mouth of the above, so that they can stop harassing themselves to solve the case.

It is impossible for Zhou Xi's case to make great progress in a short period of time with the available evidence. The only thing that can be worked on is Zhang Xian's point, and there is not much content that can be mined now.

Bi Guofeng drove around on the road and came to the Lianhe Bridge. After another 5 minutes, you will arrive near Zhang Xian's home. Bi Guofeng parked his car next to a grocery store opposite Zhang Xian's house, bought a bottle of water inside, and drank half of it in one go. Then he got into the car with the half bottle and took out a small box from the compartment. The box contained a miniature tracker, which he had brought to a friend from the Crime Unit. This is the first time he has used it in all these years.

After tinkering for half an hour, Bi Guofeng finally installed this miniature tracker into his mobile phone. He waited patiently in the car for more than ten minutes, and finally saw Chang Zhi carrying Zhang Xian's car slowly coming from a distance. After Zhang Xian got out of the car and walked into the house, Bi Guofeng pinched his watch and waited for 1 minute, and then followed him to the door of Zhang Xian's house.

Zhang Xian's family is a single family, and the lights next door have long been turned off at this time, but Zhang Xian's house is still on, obviously the family is waiting for Zhang Xian to come back. After Bi Guofeng knocked on the door, he stood at the door for a while, and then heard someone coming out of the door with slippers.

"Who?"

"I'm ......" Bi Guofeng was about to take out his police ID card, but he was suddenly stunned, "Why are you?" ”

"Who are you? Do we know each other? The person who opened the door turned out to be the woman of the couple who had come out of Lan Beili's conference room in the morning.

"Uh...... Sort of, sort of. Bi Guofeng was suspicious in his heart, why did they go to Lan Beili in the morning?

Looking at Bi Guofeng's appearance of wanting to speak and stopping, Zheng Su asked a little strangely: "Who are you looking for?" ”

"I'm Officer Bi Guofeng, I'm looking for you and your husband." Saying that, Bi Guofeng showed his ID.

"But my son has just ......"

"Who?" Before Zheng Su finished her questioning, she heard her husband's questioning voice in the house.

"It's Officer Bi......" Zheng Suwen turned around and agreed, then stepped out of the way, "Let's go into the house." ”

Bi Guofeng nodded, crossed Zheng Suwen and entered the house. After passing through the corridor, he saw Zhang Xian and Zhang Ming sitting on the sofa in the living room, and both of them stood up when they saw Bi Guofeng coming. Bi Guofeng blew his nose and said with a smile: "You're welcome, I'll leave in a while." ”

However, at this time, Zhang Ming's father and son didn't want to be polite to him at all, if they could, they wished that Bi Guofeng wouldn't come to disturb him. And Zheng Suwen rubbed her hands uneasily, she couldn't understand why her son had just been put back, and his butt hadn't been hot yet, why did the police come to the door again in a blink of an eye?

Bi Guofeng saw the vigilance of Zhang Xian's family, but he didn't see the expressions he wanted. So he didn't spare the circle, and said bluntly: "Zhang Xian, you must be tired when you just came back, go back to the room early and rest." ”

Zhang Xian was stunned, but immediately understood what Bi Guofeng meant. So he said, "Good night to my parents, good night to Officer Bi." Then he went back to his room.

Bi Guofeng nodded, and then sat down on the sofa. Zheng Suwen wanted to go to the kitchen to pour a cup of tea for Bi Guofeng, but was stopped by Bi Guofeng and said, "Ms. Zheng, don't be busy yet, I came today to verify the confession with you." ”

"Confession?" Zheng Suwen and Zhang Ming both gasped. In their hearts, if their sons had not committed crimes, their confessions would have no value. Now Bi Guofeng wants to verify the confession, which means......

Zhang Ming coughed and said, "Officer Bi, you see that our children are usually very well-behaved......

Bi Guofeng grinned, but the rotten tooth suddenly hurt again, and his smile suddenly became distorted. Bi Guofeng rubbed his cheeks and thought: It's time to make an appointment with the dentist. Zhang Ming on the side didn't know the reason, thinking that Bi Guofeng was teasing himself, and what he wanted to say just now suddenly choked.

Bi Guofeng covered his mouth and said, "Toothache...... It's an old problem. ”

"Oh......" Zhang Ming frowned, thinking: Does this person have this time to stare at Zhang Xian, but not to go to the dentist? Zhang Ming felt that he couldn't continue to talk about the topic just now, the other party obviously came to them in a private capacity, not necessarily for Zhang Xian's case, he might as well ...... Thinking of this, Zhang Ming suddenly opened his mouth, he licked his lips and said, "Officer Bi, it's like this, I have a car under my name......"

"Cars? What car? ”

"It's an Audi A8, and it's parked in the yard." Zhang Ming said softly.

"No, I'm asking why you're picking up the car with me?"

"Hehe, it's just a casual chat, you say, right?" As he spoke, Zhang Ming winked at Zheng Suwen.

Zheng Suwen didn't know what Zhang Ming meant, but he immediately nodded and said, "Yes......"

"I heard that most of your cars are still Santana?"

"That's right, it's an official car assigned by the bureau, and we all drive like this."

"That's right, I've only bought this car myself for less than half a year, and now I don't like to drive it very much, and I want to find a customer to sell it. I know that Officer Bi is well-connected, but I wonder if there are anyone I know around me who is willing to take over? ”

"Oh? So how much is Mr. Zhang going to sell? Bi Guofeng understood most of it in his heart.

"30,000 ......"

"Thirty thousand? Hehe, are you selling it or giving it away? Bi Guofeng stared at Zhang Ming sternly.

Zhang Ming was not afraid, and said softly: "Half sell and half give......

Bi Guofeng shook his head, and his heart was even more determined in his thoughts. He took out the small notebook in his arms and asked, "Next, I will ask you again the question I asked you when I took Zhang Xian away that day, if it is not necessary, I hope that when I ask one of you, the other one will not speak, do you understand?" ”

"Understood, understood......" Zhang Ming understood what Bi Guofeng meant, but he didn't know if the other party understood what he meant. His car had indeed only been driven for half a year, but Bi Guofeng in front of him seemed indifferent. Zhang Ming thought to himself: Can't this poor ghost even take out 30,000?

"Ms. Zheng, do you know where Zhang Xian was on the 17th?"

"At work."

Bi Guofeng wrote a few words in the notebook and asked: "But that day you said that on the 17th, Zhang Xian took leave and returned home." ”

"Oh, yes, I'm back home, I forgot ......" Zheng Su asked and quickly changed his words. She glanced at her husband Zhang Ming's eyes, and Zhang Ming's eyes revealed a hint of reproach, as if Zheng Suwen shouldn't even say this trivial matter wrong.

Bi Guofeng asked again: "Then did he tell you why he went home?" ”

"I said I was on leave."

"What about the reason for the leave?"

Zheng Suwen bit her lower lip and hesitated not to know what to say, that day Zhang Xian only told her that she was asking for leave to come back, but she didn't tell herself why she took leave. But if you can't say it clearly, what if you add suspicion to your son. As soon as Zheng Suwen saw Bi Guofeng writing on the small black notebook, he panicked for a while.

"Ms. Zheng?"

"Huh?"

"What about the reason for the leave?" Bi Guofeng repeated the question once.

"I, I don't know ......"

Hearing this, Bi Guofeng wrote a few more strokes in his notebook, and then lowered his voice and asked: "I learned from the company where Zhang Xian works that the reason for his leave that day was: illness. ”

"Sick...... Yes, he was sick, and I saw something was wrong with him that day. ”

"What's wrong?" Bi Guofeng hurriedly asked.

Zheng Su was flustered, thinking that he had said the wrong thing, so he quickly corrected it: "It's just that it's not right, it's not like it's in good health, you know, it's sick." ”

"Oh, good ......" Bi Guofeng thought for a while and asked, "Since he is sick, have you bought him medicine?" Or did he buy the medicine himself? ”

"Medicine ......" Zheng Su asked that he remembered that day he did see Zhang Xian return home with a pack of medicine, but should he tell the policeman in front of him about this matter?

"Ms. Zheng?"

"Yes...... It was he who bought the medicine himself. Zheng Su asked a spirit, "He has a cold, so he took a leave." Zheng Suwen was in a panic, and as a result, he revealed everything he knew.

"Cold?" Bi Guofeng pondered for a moment, wrote in his notebook for a while, and then asked: "Which pharmacy bought the medicine, when did you buy it, and is there an invoice?" ”

"You can only ask him, I don't know."

Bi Guofeng thought to himself: If she said that she had passed it in advance, she should have known. Is it a fake? Bi Guofeng peeked at Zheng Suwen twice, and secretly shook his head in his heart.

"Then after Zhang Xian came back on the 17th, did he go out again?"

"No, no, he stayed in his room since he came back and didn't go out."

"Two days, you say?"

"Yes, Zhang Xian stayed in the room on the 18th and never came out." Zheng Suwen nodded hurriedly.

"Why do you have to take a leave of absence on the 18th?"

"It's probably because of a cold, that's why I came back, rest and rest......"

"When you came back, you stayed in the room and didn't go out of the room for half a step?"

"I watched a TV series with me for a while, I don't know if this counts?"

Zhang Ming, who was next to him, glared at Zheng Su with disgust when he heard this, as if he blamed her for saying anything inconsequential.

But Bi Guofeng is not a person who dislikes details, he asked: "What TV series is it?" ”

"Lover's Secret"

"Okay, I got it."

Asked this, although Zheng Suwen's answer was not seamless, it was also logically smooth. Bi Guofeng grasped the problem of buying medicine, mainly considering where the antiemetic medicine found in Zhou Xi's stomach came from. If Zhang Xian only bought trauma medicine, then he could indeed clear some of the suspicions.

Bi Guofeng stood up and shouted to Zhang Xian's room: "Zhang Xian, don't eavesdrop, come out." ”

Zhang Xian's door opened with a "click", and he looked at Bi Guofeng with some embarrassment. As Bi Guofeng said, he has indeed been eavesdropping on them.

Bi Guofeng asked: "I heard your mother say that I bought cold medicine on the 17th, can you tell me which pharmacy I bought it from?" ”

"I bought it from a small pharmacy on Linmen Street."

"Where's the medicine now?"

"In the house."

"Is the invoice still there? Take it for me to see. ”

Zhang Xian returned to the room, Bi Guofeng heard a sound of rummaging for things, and after a while Zhang Xian came out, holding a white plastic bag in his hand.

Bi Guofeng took the plastic bag, looked through a few medicines, and then saw the invoice. He checked it carefully, and it was indeed a few medicines in a plastic bag, and the time was 11:07 p.m. on the 17th, which was 15 minutes different from the time when the antiemetic medicine was sold. And the time it takes to go back and forth from Zhang Xian's house to that pharmacy is almost this time. If Zhang Xian bought these cold medicines at the public pharmacy and then rushed over immediately......

Bi Guofeng made a silent gesture to Zheng Suwen and Zhang Ming, and then said to Zhang Xian: "Let me ask you, why did you ask for leave on the 17th?" ”

"It's just a common cold," Zhang Xian said lightly.

Bi Guofeng smiled: "Since you have a cold, why do you still have the heart to go out and drink with friends on the 18th?" ”

Zhang Xian looked at Bi Guofeng and then at his father Zhang Ming, and chose to be silent.

"Officer Bi, it's not early today, our family has just been reunited, can you give us a little time?" Zhang Ming stepped in to break the deadlock.

Bi Guofeng reluctantly stretched out a hand and held Zhang Ming's hand and said, "Yes, I'm sorry, it's so late." ”

At this moment, Zhang Ming suddenly approached Bi Guofeng's ear and said, "If you need it, please tell me." ”

"I want to ...... It shouldn't be necessary. Bi Guofeng glanced at Zhang Ming meaningfully.

Zhang Ming grinned as if he wanted to laugh, but he didn't laugh, and the atmosphere was suddenly cold to freezing. At this time, Zheng Suwen hurriedly made a haha, sent Bi Guofeng out, and did not forget to say the last sentence when parting: "Thank you for your hard work, Officer Bi." "Trying to make a good impression on Bi Guofeng.

"Oh, yes...... And this. When Bi Guofeng walked to the door, he suddenly remembered something, and took out a mobile phone from his arms, "This is Zhang Xian's mobile phone, you can transfer it to him for me." ”

Zheng Suwen accepted the phone suspiciously, and didn't understand why Bi Guofeng didn't return the phone to his son when he came out of the police station.

Bi Guofeng walked across the road and got into his Santana, and after seeing Zheng Suwen close the door, he took out the small notebook, tore off the page where he had just written at Zhang Xian's house, crumpled it up and threw it out of the car.

Bi Guofeng looked through the car window into the courtyard of Zhang Xian's house, where a brand-new Audi sedan was parked. Behind the car is a parking shed, the roof of which is connected to Zhang Xian's bedroom on the second floor, and the only window in the bedroom is not equipped with an anti-theft window. In other words, anyone can easily climb out of the window on the second floor and jump through the roof of the parking shed to the first floor.

At noon on the 17th, who was the person who bought diphenhydramine? Bi Guofeng's heart was full of doubts.
