Detectives of Detective World

Returning to the Metropolitan Police Department again, Karasawa began to ask his subordinates to collect intelligence information about Mika Mamuro.

This information is not just simple basic information, but daily information about Mika Mamuro.

Fortunately, Mika Mamuro is a celebrity pastry chef who has appeared on TV many times and is very popular with women.

Karasawa thought for a while, and first called Ayako, intending to ask her if she knew about Mika Mamuro's situation.

But it's a pity that Ayako only likes to eat the cakes she makes, and occasionally makes appointments to taste new products in the store. There is no other way to socialize.

Just like people who are often in contact with celebrities will not have the idea of ​​chasing stars. For Ayako, the other party is just a relatively famous pastry chef, so naturally he will not pay too much attention.

With no other choice, Karasawa called Sato Miwako again and asked her if she knew about Mamuro Mika's situation.

"This...I don't pay much attention..."

After hearing that Karasawa planned to investigate the life of the deceased, Miwako Sato thought for a while and said, "But it seems that Yumi was obsessed with making cakes for a while. You can ask her."

"Okay, I understand." Tang Ze nodded and then asked: "How is the situation over there?"

Sato Miwako briefly explained the current situation on the phone. After Karasawa understood it, he asked the two to continue monitoring Saotome Sami.

Although judging from the currently known information, Saotome, who wants to publish a book, absolutely does not want Mika Mamuro to die, but the other party said that the hidden things are interesting and worthy of their follow-up to find out.

After hanging up the phone, Karasawa directly contacted Miyamoto Yumi and asked her if she knew any information about Mika Mamuro.

Regarding Karasawa's inquiry, Miyamoto Yumi was very positive and said that she would bring the things from home later.

Almost an hour later, Yumi Miyamoto's voice sounded outside the door of Karasawa's office: "Hurry up and open the door, help."

"Here we come." Karasawa said quickly, and then saw Yumi Miyamoto standing outside the door carrying large and small bags.

"So many?" Upon seeing this, Tang Ze quickly took the bags one by one.

"This is all the information up to the time of Mika-chan's death. You must quickly find the murderer and avenge Mika-chan!"

Looking at the panting Miyamoto Yumi, Karasawa quickly sat her down and poured her a cup of tea and handed it to her.

"I heard from Miwako that you were just addicted for a while. Why are you so active?" After hearing what the other party said, Karasawa asked curiously.

"Who said that? I'm just too busy and don't have time to make cakes. If it's a long holiday, I'll do it."

After drinking all the black tea in the cup in one breath, Miyamoto Yumi retorted: "I have all her teachings. I even recorded the TV programs and kept them well."

"It seems that Mika Mamuro is very popular with women?" Karasawa said after hearing what the other party said: "My girlfriend also likes to eat the snacks she made."

"Damn it, you deserve to be called the eldest lady of the Suzuki family!"

Miyamoto Yumi was shocked by Karasawa's sudden "Versailles", with an expression of "envy and jealousy": "I can actually eat the cake made by Mika-chan..."

"Hey, you haven't said why she is so popular with women." Karasawa didn't want to get too entangled with Miyamoto Yumi on this topic, so he quickly changed the topic.

"Well, the reason is very simple."

Miyamoto Yumi casually picked up a magazine and turned to the column with Mika Mamuro: "Because the cake method she teaches is different from other pastry chefs.

Not only is it easy to make, but it also tastes great. "

"It's simple and you don't have time to do it?" Karasawa noticed the loopholes in Miyamoto Yumi's words and raised questions.

"That's compared to other pastry chefs' teaching methods!" Miyamoto Yumi looked at Tang De's doubts and said unhappily: "For cakes, no matter how simplified the process is, the time cost will not be much lower.

I usually don’t even have time to cook when I go back, so how could I still make cakes?

But if it is a three-day holiday, I will try to make cakes! "

At this time, Miyamoto Yumi was like a fanatic fan who spoke for her idol. She looked at Karasawa and said unhappily: "Anyway, you only need to look at these tutorials to know that Mika-chan is really working hard!

The cake making time she has researched is constantly shortening, so that everyone can make it by themselves when they want to eat it without spending too much energy and time. "

"It's an attractive place, indeed."

Tangze nodded when he heard this and said, "There are so many female fans outside."

As for men...

Emmm...

Not to mention that most neon men don't cook much, even if they want to eat cake, they will buy it directly in the store instead of going to the trouble of making it themselves.

"Right, and that's not the point!" Miyamoto Yumi showed off: "With continuous improvement, Mijia-chan's cakes no longer use powdered sugar.

This is a fatal temptation for women who are afraid of gaining weight!

And even the cake she won the gold medal in the competition was made without the use of powdered sugar. "

"kindness?"

After hearing what Yumi Miyamoto said, Karasawa immediately stood up: "What did you just say? She doesn't use powdered sugar?"

"Yes, yes!"

Miyamoto Yumi was startled by the sudden movement of lying down. She immediately realized that Karasawa might have found a clue. She quickly found the video and said:

"I have her teaching on the show here. About a year ago, Mika-chan started teaching healthy cakes that are delicious without using powdered sugar."

Yumi Miyamoto explained: "It is precisely because it saves time and can make delicious cakes that do not make you fat that Mijia sauce is so popular."

"Find out the programs and show them to me." Karasawa looked at Miyamoto Yumi and said, "According to the order of changes you mentioned, pick out a few at every other time."

"No problem." Miyamoto Yumi expressed understanding: "We just need to find out the entire process of changing the style of making Mika-chan, right?"

"It's too much trouble and a waste of time to see it all. I just need to make sure of this."

Tangze nodded and said: "Although it has been basically determined in the reasoning, if you want to solve the case, you still need irrefutable evidence!"

When Karasawa visited Akiko Sato, when Karasawa asked about the powdered sugar, Akiko Sato clearly said that the powdered sugar was used by Mika Mamuro to make cakes.

However, judging from the growth and changes of the other party, Mika Mamuro has gradually abandoned the powdered sugar and begun to develop new cakes with her own style.

In other words, Akiko Sato lied, and this was her flaw.

What Tangze has to do now is to confirm this and then put the irrefutable evidence in front of the other party.

After that, Karasawa started watching Mika Mamuro’s videos.

From the teaching at this period of time, Karasawa can clearly see that the style of Mika Mamuro's works has gradually changed.

Until later, Mamuro began to abandon sugar and butter, and began to use honey or oligomeric fructose to replace sugar.

After that, as her style matured, she never used sugar again and called her cakes "slim cakes."

"How? Did you gain anything?"

After watching Karasawa go through all the teachings she selected, Miyamoto Yumi couldn't help but ask.

"Since I learned that Mamuro Mika did not use sugar in the later stage, I have already gained something." Karasawa said: "After that, it was just a confirmation to prevent mistakes."

"Then what are you going to do next?" Yumi Miyamoto's expression perked up after hearing this: "Are you going to confront her?"

"No, this can only mean that she lied. It is too simple to convict her."

Tang Ze shook his head and said: "So now I want to conduct a reconstruction experiment at the crime scene to see how the scene exploded."

"It sounds very interesting." Yumi Miyamoto's eyes lit up after hearing this: "Can I watch?"

"If you want to come and see it, come and see it." Karasawa picked up the phone and contacted Hiroshi Saito: "Dust explosions are not common in daily life. It will open your eyes."

The top leader of Kesouyan spoke, and the arrangement of the experiment naturally began immediately.

Kesouyan already has a venue for experiments. They found an experimental venue of suitable size and began to restore the furnishings at the crime scene.

The oven and the chopping board made of the same material can be easily prepared. As for the two people in the room, it is naturally impossible to use real people, but two dummies of equal proportions are used instead.

According to Akiko Sato's description, they first placed the red dummy representing Mika Mamuro in a sitting position directly in front of the oven in the upper left corner of the room.

Because Mika Mamuro was preparing to open the oven at that time, the dummy's face was placed parallel to the oven, and the distance was just enough to open the oven door.

As for the sitting position, it was because the dummy could not be made into a half-squatting position, but this change did not affect the results of the experiment.

After that, Karasawa asked someone to place the blue dummy representing Akiko Sato at the door in the lower left corner.

In addition, he also arranged a third green dummy, and its position was placed on the right side parallel to Akiko Sato.

The only difference from the first two is that there is a large rectangular chopping board as a shield, and the green dummy is placed there in a simulated squatting posture.

However, the left hand part of the dummy was placed on the left edge of the chopping board, exposed outside the aisle.

If the oven is used as the explosion point, then the left aisle of the room is the most direct line to the explosion.

The red dummy representing Mika Mamuro and the blue dummy representing Akiko Sato were both standing on this straight line without any cover, but one was at close range, while the other was standing at the door.

As for the third green dummy that Karasawa ordered to place, only part of his left hand was exposed because he was caressing the edge of the chopping board.

The three dummies all carry data collectors to facilitate data collection after the explosion.

This experiment is a dangerous experiment such as dust explosion, but if you want to create such an environment, it is simply impossible to simulate it unmanned with current technology.

So there was no other way. Hiroshi Saito put on thick protective clothing and planned to do it himself in the laboratory.

Of course, necessary protective measures were taken. In addition to protective clothing, they also placed a strong iron cabinet on the right side of the oven with soft protective pads inside, so that Hiroshi Saito could avoid the impact of the explosion.

As for the operation, it is carried out using a long-pole stand. They have already tested the feasibility in the early stage, so there is no problem.

After everything was ready, everyone standing outside the laboratory looked into the room through the protective windows.

"Then, let's start experiments to test the wind pressure caused by the dust explosion and its impact on the human body."

After putting on the headset, Tangze asked the staff next to him to open the oven.

Soon, the monitoring computer showed that the temperature of the oven reached 200 degrees.

"Turn on the oven."

Following Karasawa's order, Hiroshi Saito picked up the long pole and used the upper shelf to jam the armrest of the oven, and easily opened the oven.

"be safe."

Tangze warned first, and then gave the order: "Push down the powdered sugar now!"

Following Karasawa's order, everyone in Miyamoto Yumi outside the window covered their ears, while Karasawa stared at Hiroshi Saito operating the shelf, pushing the powdered sugar open on the chopping board before turning on the oven.

Everyone subconsciously made evasive actions, but after the powdered sugar fell, there was no explosion. Instead, the dust filled the entire oven.

The spread of powdered sugar quickly covered the area in the upper left corner of the room, but there was no sign of an explosion in the white smoke.

As time went by, the sugar powder that filled the air with joy began to gradually fall, and the room began to become clearer.

"Failed?" Miyamoto Yumi, who was watching the excitement, looked at Karasawa and asked.

"Dust explosions require a certain special environment. Even if you know the principles of a deliberate experiment, there is no guarantee that it will definitely explode."

After explaining, Karasawa looked at the staff aside and said, "Turn off the temperature of the oven, clean the experimental site and try again."

After hearing the words, everyone started to take action, taking the tools and packing up the powdered sugar in the laboratory.

Because there were enough people participating in the experiment, the powdered sugar in the laboratory was quickly cleared away, and the environment was restored to its previous state.

The experiment was carried out again as before, and the result was also a failure like the previous experiment.

"Did you fail again...turn off the oven." After speaking, Karasawa turned on the headset intercom and said: "Saito, come out first."

"Seeing the experiment just now, I suddenly thought of something."

At this moment, Hiroshi Saito in the laboratory suddenly said: "Theoretically, as long as the powdered sugar does not come into contact with the fire, there will be no dust explosion."

"That certainly seems to be the case." Tang Ze nodded in agreement: "It seems that if you just open the lid of the oven, the powdered sugar will not explode."

"What should we do now?" Yumi Miyamoto asked after hearing the conversation between the two.

"It's easy," Karasawa replied, "just throw the powdered sugar in the oven."
