Guess 1 analysis:

The murderer not only poisoned but also beat people, which requires two conditions: acquaintances, the opportunity to poison, and the ability to know in time whether the deceased ate the poisoned food.

The waiter's bad cooking was an occasional incident, and the deceased might not have snacks in the afternoon, and even if he did, he could not grasp the time. The blond and crew cut who left were less suspicious. After checking the injuries on her ponytail, there were no signs of fraud. She could not have completed the murder plan alone.

After excluding other people, the suspects were: the bun-head (the poison was in the steamed cake), the waitress (the food was poisoned? Was something sent up later?)

-

Jian Jing put down her pen and decided to go downstairs and look around the waitress.

The right area on the ground floor was the living area of ​​the boss's family. When

Jian Jing entered the door, the first thing she saw was the photos displayed on the cabinet: a little girl was held in the arms of a zombie actor, smiling very brightly; a group photo of the boss's family and the crew; an enlarged supernatural photo... It was obvious that the family was proud of the crew's location.

"This is a photo of me when I was a child." The waitress still had a grudge against her, but she was no longer as unreasonable as last night. ""Zombie Village" was filmed at my house, and I even played a guest role."

Jian Jing smiled slightly and said in a soft tone: "You miss that experience, don't you?"

The waitress looked at her and muttered dissatisfied: "Have you really not seen this movie? It was very popular when it was broadcast. Many people came here to stay. My dad said that he made a lot of money pretending to be a zombie in the village at that time. "

"I rarely watch horror movies," Jian Jing coaxed her and walked to the window of the living room pretending to be casual. Part of the backyard can be seen from here. "You were in the house all afternoon?"

The waitress said unhappily, "What else? It was raining so hard?"

"Did you see anyone?"

"Before two o'clock, the reporter came down. About an hour later, the yellow-haired guy came in from outside. There seemed to be no other people."

Jian Jing: "Which direction did they go?"

"They all went to the lobby." The waitress said as she reconstructed the scene. "I was sitting here and could see them."

The sofa was facing the door, so she could see people coming in and out of the lobby, but correspondingly, the view outside the window was very narrow, with a large blind spot.

"Have you ever left?"

"I went to the bathroom at one or two o'clock, but I don't remember the exact time. I didn't do it again later."

Jian Jing was a little surprised at her cooperation, and smiled friendly, preparing to leave.

But the waitress hesitated and called her: "Well, did your boyfriend tell me... who did it? I saw in the news that the police have a murderer who has fled to the mountains. Is there a wanted criminal nearby?"

She tried to ask casually, but her pale face and twisted fingers all revealed fear.

Jian Jing thought for a moment, then stopped and asked considerately: "Don't you think it's a zombie?"

"There are no zombies in the world." The waitress muttered, seeming to look down on her superstition. But she really didn't want to stay alone in the room, so she suppressed her emotions and explained, "It's definitely not done by a zombie. A zombie will only suck blood, not like this."

Jian Jing deliberately said, "Didn't you say in the morning that the chicken was killed by a zombie?"

"I, I just guessed." The waitress said stubbornly, "You were the first to bring it up. I thought it was a weasel." She was a little impatient and asked, "Is there a murderer here? My dad went to town to see my aunt, and I need to be alone tonight..."

She shuddered and didn't say anything else.

"I'll go with you to lock the door." Jian Jing said, "You'll feel more at ease this way."

The waitress agreed immediately, "Okay." Jian

Jing thought she could tell whether a person was really scared or just pretending to be scared. The waitress did not promote the idea that zombies kill people, and she was afraid of living alone in the room, so she did not look like a sudden and malicious killer.

The subsequent casual chat confirmed her view.

The waitress had a bad temper, but she was not very cunning, and she was quickly tricked by Jian Jing into revealing the situation at home.

The hotel's business was indeed not good, but the family's conditions were not bad. They had a house and a shop in the town. It was just that the hotel had been open for more than ten years. It was the hard work of her parents, so they were reluctant to close it and kept it open casually.

She herself was obsessed with zombie movies and liked cosplay, but she was not so crazy that she believed it. As for the old zombie photo, she reluctantly admitted that it might be a picture of villagers performing a shaman dance.

Jian Jing smiled repeatedly as she listened.

The girl didn't know that her behavior helped a lot and greatly reduced her suspicion.

She naturally didn't say it, and slowly led the topic to another place.

"Did the deceased look okay when we had lunch today?" Jian Jing asked.

Speaking of him, the waitress complained: "He is so picky, this is not good, that is not good, and the cups are not clean, and he keeps complaining. For this place, he still wants five-star treatment? I didn't charge him for a five-star room."

"Sounds like he doesn't have a good appetite?" She asked deliberately.

"Who said that, he is fine, and he kept asking me if he could kill a chicken to eat, because he complained that the food was not good. How expensive is a chicken, 20 yuan? Besides, I don't know how to kill a chicken." The waitress said angrily.

Jian Jing seemed to be thinking about something.

Based on this statement, it is almost certain that there is something wrong with the brown sugar steamed cake sent by Wanzitou. After all, biscuits and chocolates cannot be controlled by who eats them and when they are eaten. Only the steamed cake was delivered to him by Wanzitou himself, so it is easiest to confirm whether it has been eaten.

So, was she the one who hit the deceased on the head? Did she help the murderer?

His thoughts immediately returned to the situation and brought up many possibilities.

Jian Jing frowned and stopped the subsequent speculation in time - the situation was already complicated enough. It would be too greedy to want to sort out the cause and effect in one breath, which would easily confuse his thoughts.

Since the poisoning was found first, it is better to figure out this step.

Among the common poisons, those that can cause gastrointestinal symptoms are mostly strong animal and plant poisons, heavy metal poisons, and corrosive poisons. For example, pufferfish, aconite, quinoa, arsenic, potassium hydroxide, etc.

"I remember you said that you saw the tenant of 202 come down to heat up something, right?"

The waitress nodded.

Jian Jing asked, "Do you remember what it looked like? Was it whole or cut?"

"The cut steamed cake smells good." The waitress's tone revealed a bit of jealousy, "She even asked me if I wanted to eat it, but I didn't want to!"

Although Jian Jing was full of thoughts, she was also amused by her tone.

She patted the girl's shoulder and said, "The doors are locked. You keep the key to the front door. The keys to the kitchen and the back door are with me for now. No wanted criminal will come in and start killing people. Don't worry."

"Don't think I'm scaring you. This kind of thing happened a lot before." The waitress muttered, more or less relaxed, "Do you want to have dinner? I can make more."

Jian Jing politely

declined, "No, no, I'm not hungry yet." "Forget it, I'll have a bowl of noodles myself." She opened the bag of flour and suddenly muttered depressedly, "This is all the flour left? What a pity! I don't want to go to the warehouse to get it."

She took out a bunch of noodles from the refrigerator and threw them into the pot unhappily.

- Noodles have no soul.

At this time, Jian Jing had already left the kitchen.

She went to the warehouse to examine the body and drew a tube of blood.

Ji Feng was very interested: "What is this for?"

"Do you know the difference between a policeman and a writer?" She carefully injected the blood in the syringe into the bottle. "The police must find out the whole story before they can arrest the criminal. Writers are different - don't worry about the ending. The editor is urging you to submit the manuscript. Just hand in one chapter first."

He nodded repeatedly: "I see."

"Okay, let's try our luck." She said, "Please help me call Gan Min out."

Ji Feng replied in a pleasant tone: "No problem."

Five minutes later, a girl with a ball head and a nervous look on her face walked into the warehouse and asked timidly: "You, you are looking for me?"

"Yes." The lights in the warehouse were dim, and the old light bulbs emitted a dim glow. Jian Jing stood under the light, and under the soft light, she looked more gentle and charming than usual. "I want to ask you something."

The girl with the ball head was very nervous, but her eyes could not help but follow her, and she felt a sense of closeness in her heart.

"I know you did something stupid." Jian Jing said softly, "Why are you so stupid?"

The girl with the ball head blinked. It was really strange. These words made her heart beat fast, but she also felt that Jian Jing did not want to hurt her. On the contrary, she was worried about her and wanted to help her.

"I..." She argued weakly, "I don't know what you are talking about."

"Blood, urine, bile and gastrointestinal contents can all be used to test for poisons." Jian Jing said slowly, "We'll know if there's poison in the food you gave him by checking."

The girl with the ball-shaped hair avoided her gaze: "I didn't poison him."

"It would have been great if it wasn't you." She sighed, as if she wanted to say something but stopped. "Actually, the amount of poison is not much. It's not a fatal toxin. He would have been fine after inducing vomiting. His cause of death was not due to the toxin."

The girl with the ball-shaped hair breathed a barely noticeable sigh of relief.

But the next moment, Jian Jing's expression suddenly became solemn: "The fatal injury was a blunt blow to his head, but the deceased was tall, and it would be difficult for ordinary people - for example, women - to kill him under normal circumstances. Therefore, we have reason to suspect that the poisoning was just to make him lose his resistance."

"Hiss." The man with the ball head took a breath, his face was pale, and he was about to fall. "No, it's not me."

Someone has to play the good cop.

Ji Feng's face sank and he said coldly: "Only you have delivered things to the deceased, and someone also saw you leaving at around two o'clock."

The first half of the sentence is true, and the second half is of course false. It is still unknown who the man with the broken bone saw.

However, it is enough to scare him.

The girl with the bun denied it outright: "It wasn't me, I didn't go downstairs, Xiao Wen can testify for me."

"She said so." Jian Jing shook her head and said regretfully, "She also said that you couldn't poison, but you did it, didn't you? If one testimony is false, the other testimonies cannot be accepted."

"I didn't." The girl with the bun defended, "I, I didn't poison either."

She revealed a trace of the criminal's cunning and shouted: "Even if toxins are detected in his blood, you can't say that I did it, right? Xiao Wen also ate the steamed cake, and nothing happened."

"Your steamed cake is not a whole portion, it's not difficult to mix in a poisonous piece." Jian Jing said, "Besides, since I said it was you, I naturally have evidence."

The girl with the bun pursed her lips.

"You used aconite, grind it into powder and mix it with flour to make a poisonous steamed cake. Add a lot of brown sugar to cover up the smell of aconite." Jian Jing boldly guessed, "Aconite will cause the poisoned person to have dry mouth, burning sensation, nausea, vomiting, and diarrhea. In the trash can in the deceased's room, there are some of his vomitus. Is there any digested steamed cake residue in it?"

She said, "Do you think it is possible to detect the ingredients of aconite in it?"

The air was dead silent.

Jian Jing knew she had guessed right. It was pure gambling to say aconite was pure gambling, because there were various herbal teas in the luggage of Wanzitou, which were sold in many herbal medicine stores. Compared with snake venom, pufferfish poison and other animal products, Chinese herbal medicine is the best to buy.

Among the common poisonous plants, blackhead can cause dry mouth and burnt tongue, so drink a lot of water.

She took a half step forward and said sincerely: "Xiao Min, if you don't tell the truth, how can we help you? Think about Xiao Wen, she will also be sentenced for false testimony for you."

I don't know if the aura of the charm card is strong enough, or the feelings for her best friend prevailed.

Finally, the ball head was relieved: "I did poison him, but I didn't kill him."
