"Well, that's the case," Cao Xian admitted directly:

"I went there for Yumei. My thesis project for the day came to an end and she had just started. I knew how difficult it was and didn't want her to interrupt her thoughts, so I offered to help her and came back to tell her the patient's blood pressure results and asked her to hurry up.

Rest and go back to the duty room to sleep."

Lao Hai made a note and then asked: "You should be familiar with the people in your medical team, right?"

"Um."

"Have you noticed anyone acting unusually lately?"

"No, I am the most abnormal one, right?"

"Where's the intern?"

"I don't know. They have just arrived and are not familiar with them." She said, thought for a while, and added: "If you want to comment, there is a girl assigned to our group of interns who is very diligent and proactive. Others,

Haha, salted fish."

"Where's the nurse on duty?"

"That's not clear." She shook her head: "We know each other, and we will chat when we meet, but that's it. Our work with the nurses is both closely coordinated and independent of each other, especially now that we all work electronically, there is no direct contact.

Already."

"oh?"

"Anyway, medication and other matters are directly issued through the intranet system. Family members take the medicine and hand it over to the nurse station. Other nursing measures are also issued here and received there. Usually, we all stay in the office, and they all stay at the nurse station.

, the intersection is actually not much.

Occasionally we would have a meal together, sometimes we would go to the nurse's station to pick up some things, or they would come to the office to ask something, but it was not frequent, and I really couldn't see any personality changes or anything like that."

"Okay." Lao Hai made another note, and then asked some additional questions about details that didn't seem to be very important. Cao Xian answered them one by one. After comparing his notes, he couldn't see any flaws.

"Thank you for your cooperation," Fang Changchang said, having no more questions to ask, "We already know the general situation. If it is convenient, please leave us your contact information. If you think of any clues, please inform us as soon as possible."

"Okay." Cao Xian nodded, picked up a piece of paper and wrote down the phone numbers of two mobile phones.

After finishing writing, she hesitated for a while and then asked: "Do I need to remember my address?"

"It depends on you personally." Fang Chang raised his chin: "You don't have to come to the door to inquire. It's the same as calling you to ask you out or looking for you at work. Unless you are a key suspect with real suspicion, you can leave your address or not."

Lao Hai turned his head slightly and glanced at Fang Chang.

Fang Chang caught a glimpse from the corner of his eye, raised his foot and gently lifted his calf, signaling him not to expose his secrets.

Cao Xian didn't notice their little movements. He held the pen and hesitated for two seconds before saying, "Then I'll just write."

With that said, she quickly wrote the address on the transcript booklet, signed the signature, and then returned the booklet to Fang Chang.

After leaving the duty room, Lao Hai couldn't help but mutter: "If you want someone to write, just let it go. If you don't want to, just say no. If it doesn't work, just say it casually. Why are you talking so much? Do you still expect to see her reaction further?"

Determine whether she is suspect?"

"Yes." Fang Chang raised his eyebrows: "Isn't this obvious?"

"Then what do you see?" Lao Hai said: "Not writing the address shows guilt? If you write it, you may be trying to hide it! Or maybe you hesitate for a while and then write something wrong? Then writing without hesitation may be a pretense, right?

Let me see, have you become obsessed with studying the psychology of micro-expressions recently? Do you believe that the public is right and the wife is right?"

Fang Chang rolled his eyes: "Are you questioning the role of psychology in questioning and interrogation?"

"Bah," Lao Hai curled his lips: "Interrogations and interrogations are often psychological games, how could it be useless?

But there’s no need to show off your half-baked ideas, right? Except for a few experienced experts, who can really tell the truth?

Let me tell you, except for a very few iconic typical movements, most of the other movements and expressions cannot be isolated and studied separately. People's own habits must also be considered. The same movements on the same occasion will be completely different on people of different temperaments.

Two meanings of.”

"It makes sense." Fang Chang nodded, and then he said: "No, Lao Hai, you are on fire today. Don't I just want to try my new skills? Why are you so excited to confront me?"

Lao Hai shrugged: "I'm not blaming you, I'm just telling you that you used the wrong method."

"Then what method should be used? Tell me." Fang Chang raised his eyebrows, then thought of something, and said: "Oh, I almost forgot, you are not from the police academy, you passed the provincial police recruitment examination, you are

Are you majoring in applied psychology?

Sorry, sorry, it’s been so many years, I almost forgot. Emmm, am I just trying to do what I want?”

"It's not that bad. I have almost forgotten many details that are not relevant." Lao Hai chuckled:

"I just want to remind you that best-selling books in the psychology category are sensational, or they are deliberately specious or unproven, with many mysterious and mysterious theories and very little practical information. You can just read them as storybooks or miscellaneous books.

If you really want to learn something, then buy textbooks and study systematically. Although it is a bit boring, only in this way can you really learn something."

"Okay, what do you recommend?"

"First of all, general psychology and history of psychology, these two are the foundation." Lao Hai said with his fingers: "After studying these two books, if you are still interested, then the one that is more relevant to our daily handling of cases is criminal psychology.

There are four books on psychology, personality psychology, abnormal psychology and behavioral psychology.

If you are interested, you can continue to read the psychology of micro-expressions, but I recommend the psychology of micro-movements. These two books are relatively reliable and practical among a lot of miscellaneous books on psychology."

"Understood." Fang Chang said: "I learned criminal psychology in the police academy. Let me buy other books and take a look first. There is still an intern left, let's ask him now?"

"good."

…

At the same time, the nurse is on duty in the room.

Wang Zhao and Ah Xian had just finished questioning one nurse and were questioning the second person.

"Is it early yesterday morning? I did go to the ward to change the medicine.

The patient's blood pressure dropped in the middle of the night, and the doctor prescribed blood pressure-raising drugs. The patient's fluid balance was also very disordered and needed to be corrected. Moreover, potassium injection would be very painful. The patient was also old and had poor vascular tolerance, so the infusion rate should not be too fast.

, from time to time, family members would ring the bell and have to go and have a look."

"Did you notice anything unusual in the family that was poisoned by poisonous rats in the middle of the night?"

"It's pretty good," the nurse said.

"Oh?" Ah Xian grasped the key point and asked immediately: "Have you paid attention to those three beds of patients?"

"Yes, they are also injecting fluids, and there is no one to take care of them. Every time I go there, I have to check how much of their medicine is left, and estimate the time to come and change the medicine?" The nurse asked as expected: "What's wrong?
