"Well, there is such a thing," Cao Xian directly admitted:

"I went for Yumei, my thesis plan for the day came to an end, and she had just started. I knew how hard it was and didn't want her to interrupt my train of thought, so I offered to help her, came back and told her the patient's blood pressure results, told her to rest early, and went back to the duty room to sleep. ”

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

"Hmm."

"Did you notice anyone who has been acting abnormally lately?"

"No, the most unusual thing is me, right?"

"Where's the intern?"

"I don't know, they've only been here for a short time, and they're not familiar with it." She said, thought about it, and added: "If you have to comment, among the interns assigned to our group, there is a girl who is very diligent and active, and the others, hehe, salted fish." ”

"Where's the nurse on duty?"

"Then it's not clear." She shook her head: "I know, and I will talk when I meet, but that's all." Our work with nurses is both closely coordinated and independent of each other, especially now that we are both engaged in electronic office, and there is no direct connection. ”

"Oh?"

"Anyway, the medication or something is directly issued in the intranet system, the family takes the medicine and hands it over to the nurse station, and some other nursing measures or something, they are also received here and there, usually we stay in the office, they all stay at the nurse station, and there is not much intersection.

Occasionally, they would have a meal together, and sometimes they would go to the nurse's station to get something, or they would come to the office to ask about something, but it was infrequent, and it was like a change in personality, and I really couldn't see it. ”

"Okay." Lao Hai made another note, and then asked some additional details that didn't seem too important, and Cao Xian answered them one by one, comparing the notes, and couldn't see any flaws.

"Thank you for your cooperation," Fang Chang had nothing to ask, so he said: "We have already known the situation, if it is convenient, please leave a contact information, if you think of any clues, please notify us as soon as possible." ”

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

After she finished writing, she hesitated for a while, and then asked, "Do you want to remember the address?" ”

"It's up to you." Fang Chang raised his chin: "You don't have to come to the door for inquiries, it's the same if you call to ask you to come out or go to the unit to find you." It is not a key suspect with real suspicion, and the address may or may not be kept. ”

Lao Hai glanced sideways slightly and glanced at Fang Chang.

Fang Chang glanced at it, raised his foot and gently lifted his calf, signaling him not to show his stuffing.

Cao Xian didn't notice their small movements, pinched the pen and hesitated for two seconds, then said, "Then I'll write it anyway." ”

As she spoke, she quickly wrote the address on the notebook, signed the payment, and then returned the booklet to Fang Chang.

Leaving the duty room, Lao Hai couldn't help muttering: "If you want people to write, let it, if you don't let it, just say no, if you can't say anything, what are you doing so much?" Do you still expect to see her reaction to further judge whether she is suspicious? ”

"yes." Fang Chang raised his eyebrows: "Is this unclear?" ”

"And what do you see?" Lao Hai said: "Don't write the address to show your heart? It's possible that you want to cover it up! Or hesitate for a while and then write something wrong? That unhesitating pen may also be a gesture, isn't it?

If you want me to see, you've been crazy about micro-expression psychology lately, right? The public says that the public is reasonable, and the mother says that the mother is reasonable, do you believe it? ”

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

"Phew," Lao Hai pouted: "Inquiry and interrogation are often psychological games, how can it be useless?"

It's just that you don't need to take out your half-hung ass, right? Except for a very few experienced experts, who can really say why?

If you want me to say, except for a very few iconic typical movements, the vast majority of other facial expressions cannot be taken out for separate study, and you have to consider people's own habits, and the same action on the same occasion on people with different personalities, that is two completely different meanings. ”

"That's right." Fang Chang nodded, followed by another hey: "No, Lao Hai, you are taking gunpowder today, don't I want to try the newly learned skills, why are you so excited to scare me?" ”

Lao Hai shrugged: "I didn't scold you, I just told you to use the wrong method." ”

"So what's the way to do it? Tell me about it. Fang Chang raised his eyebrows, then thought of something again, and said, "Yo, I almost forgot, you are not from the police academy, you came in through the provincial police recruitment examination, and you are an applied psychology major, right?"

Sorry sorry, after so many years, I almost forgot. emmm, am I a class axe? ”

"No, I've almost forgotten a lot of details that aren't very relevant." Lao Hai chuckled:

"It's just to remind you that the bestsellers in the psychology category are sensational, or deliberately take some specious or unproven and mysterious theories, and there are very few dry goods, so you can just read them as story books or miscellaneous books.

If you really want to learn something, then buy textbooks to learn systematically, although boring is boring, but only in this way can you really learn something. ”

"Cheng, what do you recommend?"

"First of all, general psychology and the history of psychology, these two are the foundations." Lao Hai snapped his fingers and said: "After studying these two books, if you are still interested, the four books that are more relevant to our daily cases are criminal psychology, personality psychology, abnormal psychology and behavioral psychology."

If you're interested, you can continue to read micro-expression psychology, but micro-motor psychology is more recommended, these two are relatively reliable and practical in a lot of psychology miscellaneous books. ”

"Understood." Fang Chang said: "I studied criminal psychology in the police academy, so I'll buy other books and read them first." There's one intern left, so let's ask? ”

"Okay."

……

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

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

"Was it early yesterday morning? Did go to the ward, change the potion.

In the middle of the night, the patient's blood pressure decreases, and the doctor prescribes blood pressure raising drugs, the patient's body fluid balance is also very disordered, which needs to be corrected, and it will be very painful to inject potassium. ”

"Did you find anything unusual about the strong poisoning of rats in the middle of the night?"

"That's good." The nurse said.

"Oh?" Ah Xian grasped the key point and immediately asked, "Have you paid attention to the three-bed patient?" ”

"Yes, they're also on infusions, and there's no one to take care of them, so every time I go, I have to see how much of their potion is left, and estimate the time to come and change the medicine, right?" The nurse rightly asked, "What's wrong?" ”
