Conan finally got his wish and temporarily switched from a child husband back to a detective.

He quickly got into the working state, and his expression became confident and serious:

"Lin, what do you think of this case?"

The first thing Conan asked about was Lin Xinyi's opinion.

Lin Xinyi is also a suspect and an eyewitness to the case, and his observations and thoughts are very important to the investigation.

"This case..."

Lin Xinyi replied a little helplessly:

"The biggest possibility is pure accidental sudden death."

"First of all, Mr. Zhang Tian's symptoms are consistent with sudden accidental death."

"Secondly, when I rescued him, I took off his shirt in order to facilitate his chest movement and breathing."

"So I've also paid a little attention: he hasn't found any suspicious injuries on his body, at least the upper half of his body."

"In this way, the likelihood of sudden accidental death is greater:"

"There are two kinds of sudden death: the first is sudden death from diseases that are easy to understand, such as heart disease and cerebrovascular disease."

"The second is the so-called 'suppression of death', which is not impossible."

Although Lin Xinyi did not do anything to Mr. Zhang Tian.

But there are many ways to suppress death...

Some people don't have to use their hands, and when they get emotional, they can get angry with themselves to death when they get angry - for example, Wang Situ.

can also be scared to death if you are frightened - for example, Xia Houjie.

There are even those who have killed themselves - such as the guard rank.

These are also inhibited deaths.

Even if you don't get beaten, you can still die suddenly.

"Now Mr. Zhang Tian is still rescuing, it is difficult to say whether he is dead or alive."

"And there is no news from the hospital, and we can't be sure whether he died of sudden illness or suppression."

"If it's the former, then this case has nothing to do with me."

"If it's the latter... I'm afraid I'm going to have to suffer a little bit of a loss. ”

After all, Mr. Zhang Tian died suddenly when he was entangled with him.

If no disease factors can be found in the end, the family will definitely not accept the fact that Mr. Zhang Tian died suddenly for no reason, and thus regard Lin Xinyi as the culprit who induced his sudden death.

It is not unheard of in China that there have been stories in China that discourage the elderly from smoking and discourage the elderly from smoking, causing the elderly to become emotional and die of illness, and as a result, they are falsely accused by the families of the deceased.

And Mr. Zhang Tian's family is still short of money.

People are poor and short-sighted, who knows if his family will take the opportunity to ask him for "accounts"?

If Lin Xinyi is also entangled by the other party's family like this...

Regardless of whether he wins the lawsuit in the end, or whether he loses money in the end, his reputation will be greatly affected.

"In fact, I can barely bear the financial loss and reputation damage."

Lin Xinyi is quite open.

His main consideration is not himself, but the truth behind this case:

"Now the first thing to find out is whether Mr. Zhang Tian's sudden death was an accident or not."

"Conan, I'll have to leave it to you to find out."

"Hmm." Conan nodded, and asked tentatively, "Then what do you think... Could this be someone poisoning him? ”

"There are indeed many drugs that can achieve this effect similar to sudden death."

"We don't need to guess this question, we should be able to get the answer when the rescue results come from the hospital."

"But I personally think it's unlikely that this case is a homicide."

Lin Xinyi once again gave his opinion:

Mr. Zhang Tian had an accident in a movie theater.

And the boss of Muramatsu has refused to sell the theater, and those theater employees can keep their jobs, and there is no need to hate this Mr. Zhang Tian anymore.

Since it wasn't the theater staff who did it, could it be that among the guests present, there were actually other enemies of Mr. Zhang Tian lurking?

This is a possibility, but it is very small.

"Actually, in my might..."

"If something happens to Mr. Zhang Tian, the biggest possibility is that he will commit suicide."

"Because he is now very miserable, and it can even be said that he has almost been forced to the roof by loan sharks."

"But the problem is, his sudden death symptoms of cardiac arrest... It looks like it's completely unrelated to suicide. ”

Lin Xinyi told Conan everything he knew:

Suicide or homicide are unlikely, and the most likely answer is an accident.

But whether it is for forensic doctors or detectives, the word "accident" is not something that can be used casually.

"I see." Conan nodded in understanding, "I'll find out the truth and determine if this was really an accident." ”

"Still, I have a question to ask—"

"When you rescued Mr. Zhang Tian, I saw next to me that there seemed to be a lot of water droplets on his head and face."

"Was this on his head in the first place, or was it a profuse sweat after he fell ill?"

Lin Xinyi thought for a while and replied, "It was there at the beginning." ”

"Okay..."

Conan quickly began to think:

The air-conditioning in the screening hall was sufficient, and the temperature was not high, or even a little cold.

The theater hall outside the screening hall also has central air conditioning to cool down, which will definitely not make people sweat.

In this case, the water droplets on Mr. Zhang Tian's head... Most likely, it is not sweat, but water.

"Before he came to the screening room to watch a movie, did he go to the bathroom and wash his face?"

Conan roughly guessed Mr. Zhangtian's itinerary before entering the screening room.

So he quickly said goodbye to Lin Xinyi and walked out of the screening room, wanting to rush to the men's bathroom to look for possible traces of Mr. Zhang Tian.

But Conan hadn't gotten far out of the screening room when he soon noticed a trail of water droplets on the hallway floor:

"This string of water droplets... Could it have been left by Mr. Zhang Tian when he walked? ”

This string of water droplets has been pointing at the screening room, and the people who have just gathered in the screening hall are all dry—

In other words, this string of water droplets is likely to be left by Mr. Zhang Tian.

Thinking of this, Conan immediately followed this string of water droplets and slowly groped forward.

Outcome...

Before he could find any clues, he bumped into Miss Gray Plains first.

Gray Plains was actually in this corridor, and he was still squatting, just like him, carefully observing the water droplets on the ground.

"Gray Plains, why are you here?"

Only then did Conan react with hindsight...

When he was just busy begging Lin Shinichi to agree to participate in the investigation, Gray Yuan Ai seemed to have disappeared.

Could it be that ... She had already secretly run out to investigate on her own?

"Hmm." Gray Yuan didn't raise his head, and replied lightly: "It was Lin Xinyi who was involved in this case. ”

"I'm not at ease when I hand it over to someone else to investigate."

"Well," Conan choked slightly:

He finally took the case, but he was still preempted...

This feeling is like being snatched by a roommate who has just opened a large snack when he is hungry, which makes people feel a little gloomy.

But Detective Conan quickly adjusted his mood and showed a professional demeanor:

"Did you find anything, Grayplain?"

"Yes..."

Gray Plains was still observing the string of water droplets on the ground:

"It's this string of droplets."

"Conan, you should have noticed something wrong, right?"

"Hmm." Conan's smile quietly became confident: "If this string of water droplets was left by Mr. Zhang Tian, it can explain a lot of problems." ”

"Because... The 'burrs' around this string of water droplets are very even. ”

He used the method used in forensic field science to analyze dripping blood stains.

The so-called dripping blood stain is a blood stain formed by blood dripping onto the surface of an object under the action of gravity.

Because the surface of the object where the blood drips is not smooth enough, when the blood droplets drip and collide with the ground...

A "☼ burr" will appear around the area where the blood is dripping.

"So you know that, too."

"But you didn't mean... If you want to be your great detective, don't you want to follow Lin Xinyi to learn trace analysis? ”

Gray Plains said embarrassing things without changing his face.

"Ahem... I didn't deliberately go to school..."

"He just mentioned this to me in the previous case of robbery and murder at the tram stop."

Conan's face turned red and he defended himself, and then tried to bring the topic back to the analysis of the trail of water droplets:

"In short, water droplets and blood droplets are actually more similar."

"If these droplets of water were dripping from Mr. Zhang Tian's body when he was walking normally..."

"Then the 'burrs' around these water droplets should appear to be of different lengths."

When a person is walking, the water droplets falling from the body will have a horizontal velocity.

When water droplets fall to the ground, the liquid will converge more in the direction of the velocity, and burrs will form longer in that direction.

But the string of water droplets left by Mr. Zhang Tian are relatively uniform around the "burrs".

This is a state that only appears when a droplet falls vertically at rest.

"But Mr. Zhang Tian was certainly not in a static state at that time."

"Otherwise, there wouldn't be such a long chain of water droplets pointing all the way to the projection hall."

"So, this burr uniform droplet pattern can only indicate..."

Conan confidently gave the answer:

"He was walking very slowly, almost at a standstill."

"Coupled with the short distance between these droplets, it is more certain that Mr. Zhang Tian was walking very slowly."

Because it is difficult to determine the frequency of water droplets, I don't know how long it will take for a drop of water to drip from Mr. Zhangtian's body.

Therefore, it is not possible to scientifically judge the walking speed of water droplets from the distance between them.

But by combining the distance between the droplets and the burr shape at the edge of the droplet, the conclusions drawn can be called scientifically credible.

"Why did Mr. Zhang Tian walk so slowly?"

Conan asked himself with a question.

Gray Yuan Ai also immediately said her guess:

"Because, his body was already in trouble at that time."

"Mr. Zhang Tian did not suddenly develop a sudden illness and die, but before entering the screening room, or even earlier, his body had already developed strong symptoms that made him uncomfortable."

"So Mr. Zhang Tian can't go fast at all."

"He could only hold on to the wall and slowly move forward little by little."

"It wasn't until later that he felt a little better and was able to walk on his own without leaning against the wall."

Gray Yuan said this, and added a reasoning to Conan:

"And that's why the water droplets first fell down the wall, and then they moved slightly away from the wall."

"In short, this patient of ours has long been 'sick'."

"And, Mr. Zhang Tian, he knows this himself."
