As a guest called the police, several more police officers came from the nearby police station. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The popular private restaurant has become a place of suspense.

Some of the guests who are keen on American dramas actually seem very excited, and they have a kind of CSI (crime scene investigation) feeling.

Ling Siqing led people into the kitchen, searching for clues about the poisoner.

Lao Miao and Xiao Ming were mixed in the crowd, pretending to be melon-eaters, observing the suspicious characters at the scene.

"Who else went into the kitchen today?"

In the kitchen, Ling Siqing asked.

A very simple logic, if the murderer wants to poison, he must first get into the kitchen.

Lai Hao understood what the senior sister meant, and because he understood, he was very confused: "It's strange, from morning to now, just me and the proprietress are here, Xiao Ou and Nana came in to serve the dishes." ”

"If you think about it, no one else has ever come in?" Ling Siqing asked, "Or when you went out to the toilet halfway, someone quietly touched in?" ”

"Impossible." Su Yuyan, who came in with her, calmed down her messy emotions and said, "The chef came out for a few minutes, and I was in the kitchen at the time. Except for me and him, as well as Xiao Ou and Nana, no fifth person has ever entered the kitchen today. ”

Ling Siqing didn't speak, and fell into deep thought.

Excluding emotional factors, in fact, the biggest suspect in the crime is Su Yuyan.

Maybe the hot mom is not a professional killer, but it can be like in the movie, she was forced by the villain and secretly poisoned.

However, such reasoning was too ghostly, and the female police officer quickly ruled out this possibility.

Including Ou Di, Lu Na, and Ning Yuerong in the store, Ling Siqing has all investigated, and it is impossible for these three people to harm Lai Hao.

So here's the problem......

First, how did the murderer get in?

Second, how did the murderer poison him?

Third, what kind of ingredients did the murderer put in the drug?

Police officer Lao Wu, who came in with Ling Siqing, who is experienced in medicine, examined all kinds of pork, chicken, and fish, including green vegetable tofu and noodles, and found no trace of poisoning.

There is also a question, if the kitchen has been poisoned a long time ago, all the diners in the restaurant must have been spared, how can only four people be recruited?

Ling Siqing sorted out her thoughts and asked, "Chef Su, what dishes did you cook for those four people and what materials did you use?" ”

Su Yuyan patiently recalled, and found all the remaining ingredients and materials that had been used at that time, and Lao Wu checked it, but also found nothing.

"Female officer, okay, no!"

"I'm going to work in the afternoon, can you hurry up!"

Someone outside waited until he got impatient and shouted loudly.

Ling Siqing was under a lot of pressure, she didn't find any clues, how could she go out and face Jiangdong's father?

"Officer Wu, take a look at these dishes."

Lai Hao had an idea and pointed to the dishes on a small table in the kitchen.

It was a simple two-dish and one-soup soup, and it was also a chef's lunch.

At that time, the hot mother specially opened a small stove for him, but under the pull of Da Hei, Lai Hao didn't move a single chopstick.

Lao Wu first checked the bowl of green vegetable and tofu soup and found nothing abnormal. Then I checked the plate of bitter gourd baked eggs that Lai Hao loves to eat, and found no abnormalities. It wasn't until he focused his attention on the plate of fish-flavored shredded meat that his expression gradually became solemn.

In fact, when it comes to criminal toxic substances, most police officers have no means to conduct tests and breakthroughs. Usually every city has a state-set up agency that specializes in testing, and the laboratory is tested by these institutions, and then the test report is made and handed over to the police.

Interestingly, there are exceptions to everything.

The Kowloon Branch is smoky, and it is also Crouching Tiger, Hidden Dragon.

Among the marginal figures in the Kowloon Branch, there is an old Miao who used to be known as a domestic Sherlock Holmes, and the old Wu in front of him.

Lao Wu's identity is very characteristic of the inheritor, he is an ancestral three-generation old military doctor......

It is said that Lao Wu used to be a military doctor and stayed in the army for seven or eight years, and then for unknown reasons, he transferred to the police station.

Lai Hao had a little impression of this old Wu, when he was caught in the Kowloon Branch, Kang Ping squatted at the door and waited for him, and an arrogant young police officer was very unkind to Kang Ping, and almost started to take Kang Ping to the juvenile detention center. At that time, it was Lao Wu who came forward to persuade the young police officer to retire, and then bitterly persuaded Kang Ping to leave, which shows that this Lao Wu still has a good conscience.

Seeing Lao Wu poking around in that dish with a silver needle, Chef Lai almost fell.

Uncle, your drug testing method is too old, isn't it?

Lai Hao put a question mark in his heart, seriously doubting whether Lao Wu would test drugs.

In ancient times, people used silver needles to test for poison, which was generally more reliable. Because of the limited technology of that era, most poisons had arsenic components, and the chemical term analyzed into AS2O3 was As2O3, in short, ancient poisons generally contained S ions, and silver needles could react when touched to generate AG2S, which turned from silver to black.

In modern society, many poisons basically do not contain S elements, and the composition of poisons is diverse, and the use of silver needles is already very unscientific.

Lao Wu tried it with a silver needle, but it didn't work, so he immediately changed to a new prop.

The pocket of this uncle's police uniform is like Doraemon's treasure bag, and it can conjure up all kinds of things. I saw him take out a small sealed bottle the size of his finger, which immediately contained a transparent liquid.

Lao Wu opened the bottle and dropped a small drop on the dish.

Seconds later, the unthinkable happened.

A drop of transparent liquid, the main body turned blue, mixed with a hint of heart-wrenching purple.

"I see!" Lao Wu seemed to have figured out something, and said, "Take all the soy sauce and vinegar over and I'll take a look." ”

When he checked just now, he ignored two things.

One is vinegar, a commonly used kitchen ingredient for ordinary people, which has the effects of appetizing, dispersing congestion, stopping bleeding and detoxifying. According to Lao Wu's experience, no one usually poisons vinegar, which will cause the mutation of toxins.

The other is soy sauce, which neutralizes a small amount of toxins.

Lao Wu changed his thinking, and from the perspective of a perverted killer, it is not impossible to poison soy sauce vinegar. The kind of "colorless and tasteless" poison in martial arts novels is very rare, and most of the poisons in modern society have colors and flavors, and they are mixed in soy sauce vinegar with a strong taste, but it has the effect of hiding from the world.

He checked a few bottles of vinegar in the kitchen and found no problems.

Until he opened a new box of soy sauce, he was like a great enemy: "When did this soy sauce arrive?" ”

"It's almost noon." Su Yuyan replied.

Lao Wu's expression became more solemn: "The four guests have used this kind of soy sauce for what they eat?" ”

"Yes, I opened a bottle, and this plate of fish-flavored shredded pork also uses this soy sauce." Su Yuyan's face was pale: "You mean there is a problem with this soy sauce?" It's impossible, this is sent by Sister Zhen's store, I have soy sauce, vinegar, sesame oil, chicken essence or something here, all bought from her store, and there has never been a problem. ”

"Her shop is fine, but the person who delivers the goods may have a problem." Ling Siqing interjected: "Chef Su, think about it carefully, who sent this soy sauce, and what does he look like?" ”

The implication is that even Lai Hao can hear that most of this box of new soy sauce has been dropped halfway. (To be continued.) )
