In fact, the poisoned milk or something is just a joke, mainly because Kashima Akira thinks that Kei Sakurai can't get cyanide.

Then Mitsui Shiraishi's murder weapon must still be on his body.

"Mr. Officer, can I go to the bathroom?" Akira Kashima said suddenly.

Takasaki Sugi glanced at Akira Kashima and thought for a moment, "Okay, but you have to search your body before you go, no problem, right?" ”

"No problem." Kashima said, then spread his arms and let the police come and search him.

Usually when he goes out to the police, Takasaki Sugi will bring two police officers, a man and a woman, so that it will be much easier to do things at times.

Like a body search.

But at this moment, the male police officer went to the hotel kitchen to find the two teacups, and he could only do it himself.

After searching Kashima Akira's body, there are only some personal belongings, and there is naturally no problem with private afternoon reviews.

And the metal detector did not alarm either.

Akira Kashima had no problem going to the toilet.

But since Akira Kashima has been searched, it is only natural that others should be searched.

So the female police officer is in charge of the girls and Sugina here, and Takasaki Sugi is the boy in charge of the drama club, Mitsui Shiraishi and the waiter.

Akira Kashima went to the bathroom to pee, while Nakaji Hayasaka was a little at a loss.

When he came here, he also knew Akira Kashima, so he had been following Akira Kashima all the time, and he saw the dead man before his eyes, and the whole person was in a terrible mood.

When I was asked just now, I just said something.

When Akira Kashima came out of the toilet, Takasaki Sugi asked Mitsui Shiraishi to take off the brooch he was wearing on his chest.

This brooch has always been used as an ornament on Mitsui Shiraishi's body.

Mitsui Shiraishi took off the brooch and threw it on the table casually, Kashima Akira came over at this time and picked it up: "This brooch is so beautiful, Brother Mitsui must have spent a lot of money to buy this, right?" ”

"Not much, just more than 600,000." Mitsui Shiraishi said with a smile.

600,000 yen, which is 40,000 or 50,000 yen when converted into adult currency.

Sure enough, the life of a rich person is different, such an expensive thing is thrown on the table casually, no wonder the other party has the confidence to chase Shancai.

After all, the assets are there.

Kashima Akira took a look at it and hurriedly put it down: "It's so expensive, then I'd better not look at it, I can't afford to pay if it breaks." ”

And then a look of fear for a while.

"It's okay Kashima, I can give it to you if you like it." Mitsui Shiraishi said very casually, as if he didn't put the forty or fifty thousand in his eyes at all.

But Kashima Akira still shook his head: "I can't ask for Brother Mitsui, I can't accept such a precious thing." ”

Then he walked over to the couch and prepared to sit down.

But at this moment, a rapid calculation began in my mind, not to calculate the probability that everyone is a murderer, nor to calculate who is more suspicious in the timeline.

Kei Sakurai is suspicious, but it can be put aside for the time being, and the waiter is also suspicious, but Kashima Akira saw Ono Shihua's poisoning symptoms, and he definitely wouldn't be poisoned so early.

So.

What he calculated was the trajectory of Mitsui Shiraishi's behavior!

First of all, the murder weapon must have been taken out before entering the door, and it should still be a needle or a flake or something, but considering that the gods committed the murder unknowingly, it is more reliable to have a needle, after all, if you prick you through your clothes, you can't see anything at all.

The test is also undetectable.

The vacuum can only be seen when we go back to the autopsy, but by then the evidence has already been processed.

There is no proof of death.

When he entered the door just now, Mitsui Shiraishi came to the sofa and half-squatted, so the position of his hand should be within this range.

Akira Kashima had a model of a sofa and the floor in front of the sofa appear in his mind.

Then, after deriving the first range, the rest of the place suddenly dimmed.

And when I turned around, he was in this position.

Kashima's mind also synchronized the other party's posture, his left hand remained vertical, while his right hand swung slightly inward.

So before, these were the two places that could be reached by his two hands.

At this time, only two 20 square centimeter circles were left in my mind.

One is on the underside of the cushion on the front of the sofa closer to you, and the other is closer to the armrest farther away from your left hand.

First, he quietly touched the place that was close.

Press it in a little harder and brush it over.

Suddenly, Kashima felt as if he had been scratched by something a little spiky, only touching, not pain.

"Oops!" Akira Kashima suddenly let out a cry of pain.

The people in the room immediately turned their gazes.

"There's something in the couch, it's scratched into my hand!" Akira Kashima screamed.

Couch!

This couch is where the deceased wore it before!

Wrong!

Akira Kashima, what are you going to do over there!

That was the first scene of the crime! Who allowed you to sit there!

But now it's not what they care about the most, what they care about most is that Kashima says that something is in his hand!

They also have some speculation about the murder weapon, and poisoning will definitely leave clues, so only the needle is more consistent.

But they all subconsciously thought that the things used for poisoning had been disposed of by Kei Sakurai, after all, the room card and mask were not found from Kei Sakurai's body.

At this time, Takasaki Sugi had just finished searching Mitsui Shiraishi and was about to search for a waiter, but because of Akira Kashima, he immediately rushed over.

"Where were you scratched?"

"Here." Kashima pointed.

Takasaki Sugi took out his key directly from his pocket, then cut open the cloth sofa in the hotel, and sure enough, he found a broken needle inside!

Takasaki Sugi, who was originally wearing gloves, carefully took out the needle, and he couldn't see anything from the outside, but he can now confirm that this needle is a murder weapon!

Needless to say, the needle must be poisonous.

The murderer used this needle to pierce the victim's body through his clothes, and the lack of traces of struggle at the scene shows that the victim had lost the ability to resist before being poisoned.

Therefore, according to the testimony, the tea served by the waiter must have contained some kind of substance that could make people unconscious!

So now the first breakthrough has been found!

Waiter!

In addition to Takasaki Sugi, the other two detectives also thought of this, and it just so happened that at this time, the hand that had been in the pocket was pulled out in panic and wanted to wave it, but inadvertently brought out a small piece of black fabric inside!

The waiter who noticed this wanted to hurriedly stuff it back, but was grabbed by Tan Zhen Benchuan, who was quick-eyed.

With the other hand, quickly reach into the pocket and pull out the black thing inside.

It's a mask!

And this mask belonged to Kei Sakurai before!
