The famous detective in the comic world

Chapter 334 You Killed My Husband
In short, the poisoning state they described is indeed very consistent with the symptoms of tetrodotoxin poisoning.

Moreover, it is highly concentrated.Even if the fugu is eaten without any treatment, it will not die so quickly.

It's definitely purified.

The so-called tetrodotoxin, scientific name is called amino perhydroquinazoline type compound.

It is one of the most toxic neurotoxins found in nature, and was once considered the most toxic non-protein toxin in nature.

The toxicity is 1200 times that of potassium cyanide.

Severe poisoning will result in motor nerve paralysis and death due to respiratory and circulatory failure.

And all of this happens in seconds, at most five seconds can kill.

And there is no cure.

If it was poisoned, since when did it get in?
He Nan returned to his seat and looked down at the stewed puffer fish that was knocked down on the table and on the ground.

...the juice is spilled out.

He Nan looked at the deep saucer that fell on the ground, and then observed the amount of soup.

...not a lot of juice.

And this way of eating, the juice has no taste, and no one should drink it on purpose.

However, this puffer fish can be soaked in it all the time.

This means that as long as there is a slight chance, you can poison it inside without being detected.

A small amount is enough to make the food soaked in it become highly poisonous.

tsk...

Due to the small amount, there are too many options for poisoning utensils, and the problem of capacity is also convenient to deal with...

He Nan looked at the puffer fish that moved a mouthful, and he was sure that there was something wrong with this dish.

There is only one trace of being cut by a knife and fork.

It could only be that Dad took such a bite.

dangerous enough.

If someone else ate it, it would be troublesome...

There is a high probability that the poison was given by that woman, He Nan can be sure.

But he wasn't sure if the woman intended to put the child at risk.

If she planned...then she would risk her child being poisoned to do so, it would really send chills down the spine just thinking about it.

If you don't plan to...

...That's probably another level of horror.

Because the child may be an accomplice.

Or... Her act of reminding the child to stay away from danger is enough to make people think and fear.

For example, remind the children in advance that you must not eat the puffer fish that Dad gave later...

...Will the child have a psychological shadow when he thinks of these words in the future?
Because even if the mother is not exposed, they can still know who the real culprit is...

...Speaking of which, why did this woman poison her husband in the cafeteria?

Poisoning in broad daylight is much more difficult...

Is it to get rid of a crime?

Let the chef take the blame?
Or……

He Nan suddenly remembered what he had talked about with Shirley before.

...that's cheating on insurance.

If this fooled people into thinking that the chef's mishandling of the fugu caused her husband to be poisoned, a huge insurance policy might have been awarded.

The Heart Demon Gang and the Atlantic Cafeteria may also give her an additional compensation for the sake of peace.

If this is the case, this woman spent a lot of money in poisoning to successfully disguise... It's a pity that her brain is not very good.

The concentration of the drug is too high, and one should not pursue such a quick death, otherwise the opening will be too big.

He Nan has not learned about the market price of purified tetrodotoxin in the past two years, nor has he encountered anyone using this poison to kill—after all, the cost is too high.Potassium cyanide is much cheaper and more affordable.

But when he was in school, he studied.

The undiluted price per gram of tetrodotoxin is around $[-].

One kilogram of tetrodotoxin costs [-] million US dollars.

Where is this tetrodotoxin expensive?
The first is concealment, the other party is not easy to find after poisoning.

Then it is fatal and cannot be rescued.

And then there is...

Process and raw material costs are too high.

Every gram of tetrodotoxin requires [-] kilograms of puffer fish ovaries to extract.

Just as he was thinking this way, the woman hurried over accompanied by the younger brother of the Heart Demon Gang.

She looked very distressed and in tears.

The moment she ran to see her husband's body, she cried and wanted to run forward, but was stopped by the younger brother of the Heart Demon Gang.

"Let me in! It's my husband who died...! Woohoo...I just left for a while, why did this happen...how did he die?! What did he eat?! Your restaurant must give me one today Confess!"

"Please calm down, ma'am, those two detectives are investigating the cause of your husband's death." Liu Hong said, calming down her emotions.

No one has told her that her husband died of tetrodotoxin poisoning...

He Nan looked at the lady, nodded to her, his face remained calm, but he was thinking about it in his heart.

...Since this is the case, how can she be sure that the restaurant is responsible and that she died because of what she ate?
Of course, He Nan can also understand that there are indeed situations where innocent people say this sentence directly.

First of all, because this is a restaurant, or a seafood restaurant... there are inherent risks in some ingredients.

Secondly... It is not surprising to find the responsible party as soon as possible after the accident.

"Miss Detective! How did my husband die?" The woman wiped her tears and looked at Shirley: "Have you found out? He was fine a few minutes ago!"

"We are investigating." Xue Li exchanged glances with He Nan, and then said with a serious and calm expression: "At present, it can be judged that the death was caused by poisoning, and the specific source of the toxin is unknown."

"Then...then what should we do?" The woman said anxiously, "Please find out the truth!"

"We will try our best." He Nan said, then turned to ask the two children intentionally, "Did you see what the dead man ate at the end?"

"I see." The little boy said, sobbing, "It's a puffer fish..."

"...Mmm." The little girl also nodded: "After Dad ate the fugu, he immediately felt uncomfortable..."

As soon as this remark came out, the customers immediately became commotion.

They all yelled in fear, saying that they died from eating fugu. The fugu in this shop must not have handled the toxin properly!
Some people asked in a panic that if they had eaten fugu before, would something happen to them afterwards?

... There was even an actor who immediately yelled that he was starting to feel unwell, and that he should be sent to the hospital quickly.

And the woman also broke out a new round of crying under the commotion.

She scolded the shopkeeper for killing her husband, and even cooked poisonous puffer fish for him to eat.Now that someone is dead, what can she do?At the same time, she also complained that she didn't let her husband eat such a dangerous thing in the first place, and insisted that she would not listen. What happened now is really God's punishment for not insisting on dissuading her.

For a while, the Heart Demon Gang also seemed a little flustered, and began to desperately maintain order, asking everyone to calm down.However, the restlessness still could not be quelled.

From He Nan's point of view, the woman's behavior was that she had been expecting this commotion for a long time.

It made him even more suspicious of it.
