The two walked side by side, each thinking about his own things.

In the morning, Tan Yi sat in the hospital, checked the entire list of patients in the inpatient department, compared all the target persons, and found no valuable clues.

He thought that even if there was no evidence to support it for the time being, the thinking logic of a normal person would not be too different.

If the logic is correct, there must be a key point that has not been discovered.

So what is this key point?

Medical staff, cleaners, patients who have recently entered and exited the inpatient department, and regular bedside personnel have all been checked and have nothing to do with Hou Zian.

In addition to the above, there are also relatives of patients who had been discharged from the hospital before Hou Zian was killed.

This is a difficult point. If you want to check, you have to send someone to re-interview and get a deeper understanding.

Xie Qing is considering what to eat for lunch.

Before she even got to the cafeteria, she smelled the aroma of braised pork in red sauce. With braised pork in red sauce, she didn't need to think about anything else, just some vegetables.

As she was thinking deeply, two colleagues came over and were discussing a case of the first team. Xie Qing listened to them at the same time.

At this moment, Tan Yi suddenly said something.

Xie Qing seemed to hear him ask, "What are you going to eat later?"

She answered without thinking, "Braised pork."

Tan Yi looked at the furry bun on her head, "Do you like braised pork?"

Xie Qing thought she had heard it right, and said with a smile, "Of course, the chef's dish is excellent, fatty but not greasy, fragrant and delicious."

Tan Yi raised his eyebrows, "No wonder."

Xie Qing said, "No wonder what?"

Tan Yi said, "I just asked you, do you have anything to do later?"

Uh...

it was a little embarrassing.

Xie Qing pinched the strap of her schoolbag, decided to ignore this point, and answered the question directly, "Probably not. I plan to go to the hospital this afternoon and participate in the investigation. Is that okay?"

Tan Yi said, "I'd love to." This was what he meant originally. Xie Qing was meticulous and had a talent for criminal investigation.

The two reached a tacit understanding and stopped talking, and went into the cafeteria

one after another. Tan Yi was called over by Director Yan as soon as he entered the door.

After Xie Qing finished her meal, she bumped into Cao Haisheng, who was about to finish his meal, and told him about the afternoon arrangements.

Cao Haisheng had no objection, so she went to the city hospital after dinner.

Xie Qing thought that if the murderer was a patient, he might consider being discharged from the hospital as soon as possible, but it could not be ruled out that he had a good psychological quality and was quietly waiting for the case to reach a dead end.

If the murderer is a family member of the patient, he may consider transferring the patient to another hospital or finding someone else to take care of him. Of course, the same situation as above is not ruled out.

If the murderer is a hospital staff, this seems unlikely. As long as he is not a perverted murderer, Tan Yi should have found clues.

...

There are too many variables and too many targets. This is the dilemma faced by all criminal police, including Tan Yi.

If Xie Qing assumes that she is the murderer, she will not choose to kill after being discharged from the hospital. Under the premise of absolute confidence, she will stay in the hospital and keep abreast of changes in things.

After all, it is dark under the lights, and it is less likely to attract the attention of the police.

But referring to the murderer's behavior of not wearing gloves when committing the crime and wiping his fingerprints when he went back, Xie Qing felt that the murderer's psychological quality was not very good, and he was only brave.

…

While waiting for the red light, Xie Qing had a lot of random thoughts. But once she entered the inpatient department, she calmed down. People are very different. You can’t solve a case by imagination and reasoning. You have to start from reality.

She studied the floor plan of the inpatient department and decided to take the elevator up and screen from the top floor down.

The nurses at the nursing station were busy, and the police didn’t want to disturb them again and again, but there were still many bored patients and their families.

In order to not miss anyone, Xie Qing planned to go to each room one by one.

Soon, she knocked on the first ward door and greeted the old lady sitting on the chair, "Hello, grandma."

The old lady had a kind face and smiled back immediately, saying to the old man on the bed, "Old man, this little girl is so pretty."

Xie Qing took out her police ID, "Grandma, I'm a policeman, I want to talk to you, do you have time?"

The old lady slapped her thigh, "Hey, policemen, it's rare to see such a good-looking policeman, I thought he was a big star! Old man, don't you think so?"

The old man lay on the bed, staring at the ceiling, and did not respond to her.

The old lady said, "My old man has been smart all his life, and now he can finally take a rest and listen to my chatter every day."

Although the old lady was optimistic, Xie Qing still felt the bitterness behind her words.

Xie Qing said, "You are still open-minded."

"Well, if you are not open-minded, you will only make things difficult for yourself. Everyone will have this day when they get old. It is a blessing to die suddenly..." The old lady started talking and continued to talk nonstop.

Xie Qing interrupted her several times, and the old lady went back several times. Her first battle was a disaster, and it took her 20 minutes to successfully escape.

Fortunately, the other rooms went smoothly. She answered all the questions and it took about three to five minutes to finish each room.

After walking around several floors, it was almost time to get off work.

Xie Qing memorized several key points, drank some water, and prepared to go back to the office.

Before leaving, she went to the bathroom.

While squatting, I met two nurses who were putting on makeup at the sink.

"Hey, the old lady in 603 is unattended again."

"Wasn't there someone there yesterday? Well, don't worry about it. I think the family is okay. They won't ignore her."

"What's okay? They fish for three days and dry their nets for two days. The old lady pulls the mattress every other day."

"I said, the thing on the fifth floor... do you think it could be his family?"

"Impossible, his family changes like a revolving lantern. In my opinion, it's not as likely as the family of the second bed in 318 on the third floor."

"What's wrong with that person?" "

Xiao Zhang said that he didn't take good care of the patient. The patient was still on IV drip, and he just wandered around. He died several times."

"How old is he?"

"About 30 or 40 years old, hanging out everywhere."

"That doesn't look like that."

"Hahaha, that's why I didn't dare tell the police."

Xie Qing was depressed. She thought she had heard some important clues, but that was all?

She pulled up her pants and was about to take a shower when she heard the conversation outside.

"Do you think there's anything suspicious?"

"I'm telling you, there really is."

The nurse lowered her voice.

Xie Qing couldn't hear anything, so she quietly pushed open the door...

"I heard from Xiao Wang that in Ward 421, there is a man in his forties who delivers meals to a patient from the countryside every day. He said he is a relative, but the relationship is not too close."

"Isn't that normal?"

"Xiao Wang said he saw him coming down from the fifth floor."

"That night?"

"That's not the case. It was a few days ago in the afternoon, around five or six o'clock."

"Well, there are so many people going to the fifth floor. Did Xiao Wang tell the police?"

"No, she just complained to me. Forget it, maybe he has acquaintances on the fifth floor. We can't easily offend people in our line of work."

...

The two left the bathroom.

Xie Qing also walked out of the bathroom.

She had just learned about the first two situations mentioned by the two nurses, and she had just heard about the last one.

The police's target is people who are often in the hospital, so when questioning, they will emphasize the length of time and ignore the frequency. It is normal to miss something.

After washing her hands, she went to 421 - this location is very close to 524, and it only takes a few seconds to get there by walking up the east staircase.

Xie Qing entered 421 for the second time .

There are three beds in the ward, and one of them is occupied by an old lady.

She had asked before, and the old lady was from Qingshanya, and her eldest daughter was accompanying her.

Both mother and daughter are not good at communicating, and they only answer one question at a time.

Xie Qing asked, "Sister, who delivers meals to you every day?"

The elder sister looked at Xie Qing warily, "Why are you asking this? He can't possibly kill anyone. He delivers meals and leaves every day, and rarely even enters the house."

Xie Qing said, "I'm just asking."

"What are you asking? Are you police officers too idle? You ask several times a day, one leaves and another comes, and there is no time to rest." A middle-aged man in the next bed spoke up with a very aggressive tone.

"That's right, the person has been dead for so long, and you don't even have a rough idea of ​​the murderer. What are you doing?" The middle-aged man's wife also helped.

The old lady in the third bed said, "A village person delivers meals every day, which is better than my son and daughter. Don't ask around, little girl, he must be a good person."

Xie Qing understood.

They didn't say it before, and they might not know that the man who delivered the meal was also a suspect, but they just thought he was a good person and shouldn't be associated with such trouble.

Although they had good intentions, it was not advisable.

In this case, Xie Qing felt that it was probably unreasonable, so she said, "Sister, if you don't say it now, if he gets into trouble in the future, you will be suspected of shielding a criminal."

A man pushed the door open with a lunch box, "Shielding what?"

"Hey, Pi Saner, what are you doing so early?" The sister complained and took the cotton bag from the man.

The man smiled and said, "Isn't it time for lunch? What's wrong?"

The middle-aged man in the second bed said, "You just delivered a meal, but they suspect you of murder?"

"Ah?" The man panicked, "This little girl is a police officer?"

His eyes met Xie Qing's.

Xie Qing asked, "Are you selling cigarettes and alcohol?"

The man admitted frankly, "Yes, just outside the Sunshine Community. Have you bought cigarettes and alcohol in our store?"

Xie Qing nodded, "Do you know Hou Zian?"

The man said, "He bought cigarettes in my store. I saw him a few times, but I don't know him."

Xie Qing said, "You know he's dead, right?"

The man said, "Of course, the police also went to my store to ask about his whereabouts. , he often goes to the Sunshine Community. Are you a policeman? I didn't kill him, there is no grudge between us. "

Xie Qing smiled, "Our leader said that we must screen the people in the hospital carefully, so don't be nervous, it's just a routine matter."

The man exaggeratedly breathed a sigh of relief, "Don't be nervous, don't do anything shameful, you don't have to be afraid of ghosts knocking on the door. Oh, little girl, I didn't mean to say you are a ghost."

"It's okay, it doesn't matter if you scold me, I'm used to it." Xie Qing said, "Brother, leave a name, I can report back when I go back."

The man said: "Pi Yan."

"Ah?" Xie Qing almost laughed out loud, "Dermatitis?"

Pi Yan said, "Excuse me, my parents are ignorant and didn't know there is a disease called dermatitis, so they gave me this name. Seriously, you can just call me Pi Saner."

Xie Qing said, "Okay, then I'll leave, you two can chat slowly."

Pi Saner insisted on sending Xie Qing out and asked, "Little girl, haven't you caught the person yet?"

Xie Qing said, "Not yet."

Pi Saner said, "Alas, a good person died so tragically, you'd better catch him quickly."

Xie Qing said, "Okay, please stay."
