You die and die

Yu Guang's expression was like being stuffed into a big duck egg, still with the shell on, he was almost out of breath, his calm look just now was swept away, his eyes were not only surprised but also puzzled.

If Yuan Che hadn't known about Ke Ran's condition, he would probably have the same expression as Yu Guang at this moment.

In order not to show his feet, Yuan Che hurriedly took the book with both hands, interrupting his gaze from the corner of the eye.

Looking back at Yuan Che from the corner of his eye, he smiled concealedly: "If I write a book about the people's police in the future, I may have to learn from the two of you. I wonder if it is convenient for Fang to leave a contact information?"

Yuan Che put the book aside, and was about to take out his mobile phone when Ke Ran handed him over:

"Let's keep mine. He's too busy, I'm afraid he won't have time to answer the phone."

Yu Guang hesitated for a moment, seeing that Yuan Che had no intention of objecting, and finally entered the phone number on the phone: "This is also my WeChat account. Please make a note when you add me."

It's not that Yuan Che didn't object, but he didn't react.

He always couldn't figure out what this Ke Ran was thinking, he was a mystery from top to bottom.

Ke Ran did not continue to complete the action of adding WeChat, but directly put the phone into his pocket, hummed casually, then raised his eyebrows at Yuan Che, and twitched the corner of his mouth with a half-smile.

Stimulated by Ke Ran's expression, Yuan Che hurriedly picked it up and stood up: "Send it to me later, and I'll add it too. Excuse me, we still have urgent matters."

The two adults said a few more polite words before leaving the room.

The female assistant handed Yuan Che a copy of the registration form.

Yuan Che hurriedly thanked him, and pulled Ke Ran who was wandering around the assistant's desk out the door.

Fortunately, this Ke Ran can be touched.

Before the holiday, Yuan Che received a reply from the teacher.He said that Ke Ran is excellent in all aspects, but he is a bit introverted and seems to have no friends.During his college days, he has been studying day by day, and his participation in school activities is limited to doing physical work.

He showed no duplicity at school.

He also asked the psychiatrist, and the doctor said that it was difficult to make a judgment because he did not see himself.But as far as the situation of Ke Ran he described, there are few cases in the world, so there is currently no effective way to treat it.

Although Ke Ran hasn't caused any trouble because of this sudden switch for the time being, it's inevitable that he won't in the future.

Ke Ran's family probably didn't know that Ke Ran was sick, and if they knew, they probably wouldn't let him go out.With their connections and strength, they will definitely find the best psychologist to treat him.

After much deliberation, Yuan Che still felt that it would be better to persuade Ke Ran to quit.

After entering the elevator, Yuan Che glared at Ke Ran: "You really came at a bad time."

"Hehe, I think it's better to come early than coincidentally. Why, you want to add him on WeChat."

"Can't you? After all, not everyone has the opportunity to add WeChat with well-known writers."

Ke Ran took a book from Yuan Che's hand: "You really like his books? I took two."

Yuan Che smiled wryly and said, "I don't like it." He poked Ke Ran's shoulder, "It's the other one you like. There is another one for Xiao Wu, who asked me for it yesterday."

"Cut, he really has no taste." Ke Ran changed the topic, "Who are the ugly pair? Is there a new case?"

Yuan Che looked at the time: "He was killed about two hours ago. This is the place he visited before he died. Let's stop by and have a look."

Ke Ran pointed to his nose: "You don't come here for a bad guy, do you? You dote on him too much."

"Do you think I will be so idle?" Yuan Che changed the subject, "Ke Ran, if your situation is known, you will be fired. Let me give you a suggestion to resign automatically before you are fired, so you can save face .”

"What's the use of you telling me, it's not that I want to be a policeman."

"But you can help him, and I can help you too."

Ke Ran didn't answer, and stepped out as soon as the elevator doors opened.

The exit was not the same as the one that came in before, so Ke Ran turned around to find the exit.

Yuan Che could see that he did not intend to continue this topic, and what he said just now was also duplicity.

After exiting the revolving door, Ke Ran couldn't bear to be curious and asked Yuan Che about the details of the case.

Yuan Che succinctly said that Liu Hecheng called just as soon as he mentioned that Liu Hecheng was looking for surveillance.

He had two discoveries: one was captured by the surveillance cameras at the intersection. When Chou Shuang passed the intersection, a scavenger followed him with his pocket.But I don't know if they have been following the scene of the crime; one is Ugly Shuang who started talking on the phone with a selfie stick shortly after leaving the building.

Scavengers generally have a fixed range of activities, don't change their clothes very much, and have obvious targets.

"Do you need a selfie stick to talk on the phone?" Yuan Che asked.

"You need a selfie stick for live streaming," Liu Hecheng replied.

They were waiting for a traffic light at an intersection when the phone hung up.

Ke Ran poked Yuan Che: "Just now I saw a check on that female assistant's desk, it's from this bank. Would you like to sit on the sidelines and talk to her?"

"What are you talking about?"

"I think that writer has been doing Tai Chi, and the content of the answer has no useful information."

"Perhaps there really is nothing useful? He has no reason to hide."

"Who said no, you heard it just now. He said that this person is talkative. Maybe he is a pervert who can't stand talkative people?"

"Then it's possible that everyone in the office is his accomplice. Or he used invisibility. Otherwise, if he came out of the room as a living person, no one would see him?"

"So you have to ask, maybe he really found an excuse to come out?"

Yuan Che looked at the bank next to him, and then said: "You must have evidence for what you say, and you can't guess it out of thin air."

"Do you guess that you will know if you ask?"

Yuan Che was about to refute, when Ling Xiaoyu called and said:

"The cause of death and the murder weapon are consistent with the previous case, and the silk scarf is also of the same style. Judging from the depth of the penetration, it is almost certain that the murderer is the same person. The cause of his death was that his heart was cut in half by an ice pick. Before the murderer pulled out the murder weapon , pulled the ice pick.

The piercing position of the ice pick is from top to bottom.The deceased was 178 centimeters tall.Taken together, the murderer should be a male with a height of more than 180 centimeters.

In addition, his blood tests showed that the white blood cell count was lower than normal, and the contents of the stomach contained red wine.Combined with the bloodshot eyes and the drunkenness described by witnesses, I suspect that he had a disulfiram reaction in his body before his death.That is to say he drank alcohol after taking cephalosporins.No capsule coat was found in his stomach. Please find out when he took cephalosporin drugs, whether it was a tablet or a capsule. "

Yuan Che held the phone between him and Ke Ran, and Ke Ran hurriedly asked, "Has he ever had coffee?"

"Drink it. He also ate beef and some broccoli. The last meal was Western food."

"Is it possible that the cephalosporin was drunk with coffee?"

"That will reduce the efficacy of the medicine... You mean, someone deliberately put cephalosporin in coffee for him to drink, and he drank without knowing it?"

"is it possible?"

"It's not impossible. The bitterness of pure coffee will mask the bitterness of the medicine, but there will still be a slight difference. Unless the person doesn't drink much coffee and can't tell the difference. If so, it may be premeditated murder. In Disulfiram Under the action of the reaction, the deceased lost most of their resistance."

Yuan Che asked: "Is there anything else to discover?"

"There are secretions from his own mouth around his mouth, which are distributed irregularly. This is caused by the large amount of secretions produced in his mouth due to drug reactions, which were squeezed. The deceased had his mouth covered before his death. Others there is none left.

"Okay, thank you for your hard work." Yuan Che hung up the phone, looked at Ke Ran, "What did you find?"

"It's nothing, but the coffee machine in Yu Guang's studio should have been used today."

"How do you know it's for today?"

"Don't you think his room is very clean and tidy? And the assistant also wiped the hand sanitizer for the guests. It should not be aimed at us, but the habit of all visitors. This shows that he is a clean person. So clean After using the coffee machine, people should clean it up very well. But I just saw that there are a little coffee marks on the outlet of the coffee machine that have not been wiped clean. Moreover, the peripheral vision is quite high, and I think it is about the same height as you."

"Ugly Shuang left the western restaurant at one o'clock, and arrived at the scene of the crime around 28." Yuan Che looked at his watch, "It takes 15 minutes to walk from the building to the scene of the crime, which means he doesn't have time to have coffee downstairs." Drinking coffee in the living room. We first need to rule out whether he is drinking coffee at home."

Yuan Che called Liu Lingling on the phone, and there was faint crying on the phone. Liu Lingling lowered her voice and said that she hadn't had a chance to ask too many questions, and that Chou Shuang's family had been in grief.

Yuan Che asked Liu Lingling how his family was, and Liu Lingling said that he was a working class, and Chou Shuang didn't seem to have a decent job.

If this is the case, he should not be the kind of person who just eats a [-] yuan meal.

He also asked Liu Lingling to ask Choushuang's family members whether Choushuang had the habit of drinking coffee, whether he drank coffee at home today, and whether he had a cold or sickness and took cephalosporins for cold medicine.

Liu Lingling agreed.

Yuan Che glanced at the signal light that had turned green, turned around and saw the female assistant coming out of the building and was about to cross the road.

"How's it going? Go ask?" Ke Ran bared his teeth and smiled, which was particularly hateful.

Yuan Che didn't nod or shake his head, but just walked towards the bank.

Seeing that the female assistant entered the bank soon, they waited outside.

While waiting for someone, Yuan Che sent the two mobile phone numbers he had just obtained to Technician Li, asking him to check the identities and addresses of the two book fans except Chou Shuang.Registering a mobile phone with a real name provides considerable convenience for finding someone.

When the female assistant came out of the bank, she was stunned when she saw Yuan Che and Ke Ran standing at the door. The smile on her face was not as sweet as it was in the studio, but she was still polite.

"Comrade policeman, what a coincidence, you also come to the bank to do business?" She should have seen that the two of them were here specially to wait for her, so the tone of the question was slightly teasing.

"Do we want to ask you for some information?" Yuan Che said.

"What's the situation? I don't know if I can help. Besides, haven't you already asked Mr. Yu?" The assistant's eyes drifted back and forth between the faces of Yuan Che and Ke Ran, and when it came to Mr. Yu's three When writing words, I raised my chin with a proud expression

"It's still about those few book fans. I always feel that women's observation skills have always been more keen than men's. Maybe you can see the details that we don't pay much attention to."

After being told by Yuan Che, the assistant's slightly repulsive expression eased a little earlier, and she looked at the time: "Okay, but hurry up, I still have a lot of things to do."

"We can talk as we walk, and if you don't feel awkward, we can buy you a cup of coffee."

"See how much you have asked. What do you want to ask?" The assistant walked towards the intersection.

"When did you first know about Ugly Shuang?" Yuan Che asked.

"It was the signing, you were all there. That was the first time I saw him." They stopped at the intersection and waited for the traffic lights.

"When he came today, was there anything strange?" Yuan Che asked.

"If you want to say it's not weird, it's annoying." After she finished speaking, she seemed to feel that her tone was demeaning, and quickly explained: "If you ask me how I feel, I will tell the truth. Maybe Teacher Yu doesn't feel anything, but we are angry. died."

"What? Did he do something annoying?"

"He's been asking questions all the time, pretending he doesn't know as much about anyone as he does."

"What questions did he ask?"

"It's about Teacher Yu's private life."

"for example?"

"A lot, I don't remember exactly."

It seems that it's not that she doesn't remember, but that she doesn't want to say it, and she regrets that she was so talkative just now, obviously she really defends her Teacher Yu.

Yuan Che changed the question: "What has he been doing here for an hour? Just talking?"

"Just looking around, we took them to learn about Teacher Yu's work."

"You take it? Is Teacher Yu busy?"

"That's not true. He is very happy today, saying that he grinds coffee for them himself."

"Is he doing things like grinding coffee by himself?" After the green light turned, Yuan Che walked to the assistant's left.

The assistant glanced at Yuan Che, seeing that Yuan Che's action was so helpful, he spoke in a much softer tone:

"He bought a coffee machine to write a barista character and studied how to grind coffee. He seemed to be addicted to it for a while, and he made our coffee every day. But it has been a lot less recently."

"I remember that at the signing meeting that day, Ugly Shuang said that Mr. Yu often experienced life, and asked him if he also experienced some setbacks like in "Bitter Candy", otherwise how could he write so profoundly. Is that so? ?”

"Didn't Teacher Yu say, 'If a writer has experienced all the stories he writes once, how many times will he have to live and die?'. However, Teacher Yu pays attention to details, and he often looks for materials."

"What about today? Did Teacher Yu go to collect materials too?"

"No, I didn't go because there was a video meeting today. He usually goes in the morning or afternoon. Occasionally he will take us around other cities. Noon is Teacher Yu's regular rest time. What important calls, visitors? Never welcome."

"He rested, did you also rest?"

"We rest for an hour from twelve o'clock to one o'clock, take turns to eat, and then we have to deal with some materials of Teacher Yu. Why do you ask me this?"

They had already entered the building, Yuan Che walked to the bar, ordered two cups of coffee, and then found a place to sit by the side.

Yuan Che waved his hand at Ke Ran, Ke Ran took a while to understand, took out the small notebook in his pocket, and wrote down what the assistant said just now.

Yuan Che suddenly showed a very embarrassing look, scratching the back of his head: "Actually, the scene was a mess that day. I'm really sorry. I don't know if it has affected Teacher Yu's creative mood."

"Then you don't worry too much. We had a celebration banquet and karaoke all night. We were very happy."

"Karaoke? Could it be 'Singing Ba' KTV?"

"how do you know?"

"Coincidentally, I went there that day. I said how I saw someone who looked like Teacher Yu. I think it was around eleven o'clock."

"Did you see us?"

"No, Teacher Yu is alone."

"You read it wrong. We didn't arrive until then. We sang until it was a little faster. Teacher Yu got drunk and lay down and fell asleep."

Next to Ke Ran pretended to cough: "Should we ask the question?"
