Ke Xue: Shinichi and I are childhood friends

"Inspector, we didn't find anything like an ignition device at the scene." The forensic officer who had finished checking the scene ran over to report.

"No ignition device?" Inspector Yumio touched his chin. Without an ignition device, the only possible source of fire was cigarettes. "In that case, was the fire really an accident?"

During this time, You also observed the garage.

The antique car was quite miserable. It was completely burned. Even one of the doors was blown off and fell not far from the body.

In the bag on the ground, there was a pack of unopened cigarettes, a lighter and some sundries.

The cigarette suspected of being an ignition device was completely burnt, so it was impossible to tell whether it was the same brand as the cigarette in the bag.

Of course, if this was really a murder case, the murderer would not make such a low-level mistake. Putting a cigarette that the deceased didn't usually smoke would be self-defeating...

However, if the fire source was not a cigarette...what other ways could it be ignited?

Yuya stroked his chin and scanned the garage, but he didn't find anything relevant.

He glanced at Ginbayashi Ena who was talking to Inspector Yuminaga, and turned to look at the forensic officer: "Mr. Forensic Officer, are there no other items at the scene except this bag and the burnt cigarettes?"

"Yes." The forensic officer brought an evidence bag with a blackened key in it. "This is the key of the antique car. It seems to have been affected by the explosion and flew out of the garage. It was almost missed."

Yuya took the evidence bag and took a look. It turns out that this kind of antique car uses a key? His sports car uses an electronic remote control...

Speaking of which, Dr. Agasa's Beetle and Gin's Porsche also use keys. They are all older cars, which match their ages...

No, how old is Gin? He should not look 30 years old, right? Yuya's thoughts wandered for a while.

Shiho Miyano had been following Yuya. Seeing the car keys, she couldn't help but say, "Compared to the keys, the remote control is more convenient."

Yuya came back to her senses and looked at her in confusion, "Huh? What do you mean?"

Shiho Miyano pursed her lips and said, "When it's cold and I wear a sweater, if I get out of the car and lock the door with the key, there will be static electricity when I touch the car key. I don't like that stinging feeling, which makes me feel bad."

Yuya was stunned for a moment, grabbed Shiho Miyano's hand and asked, "What did you just say?"

"...I will feel bad?"

Yuya subconsciously cared, "It's okay, I'm here..." Paused, "The sentence above..."

Shiho Miyano glanced at him with a slight movement of her eyes. This guy always makes you feel moved inadvertently, and said, "There will be static electricity when you touch the car key. I don't like that feeling..."

"That's it!" Yuya kissed Shiho Miyano's face hard, which immediately attracted the attention of several police officers nearby.

Brother, this is the crime scene, okay? Thinking that I am still a single dog, I can't help but burst into tears.

Miyano Shiho was stunned for a moment, her ears turned red, and she pretended to look calmly at the side... the burnt and deformed plastic barrel.

"If it is static electricity, it can indeed ignite. In this case..."

Youya glanced at the car keys in his hand, walked quickly to the forensic officer and asked: "Mr. Forensic Officer, can you tell what clothes the deceased was wearing today?"

The forensic officer was stunned for a moment, and habitually answered: "Based on the burning residue on the surface of the body, it can be roughly inferred that it is wool or fluffy clothes."

"I know this," At this time, the woman who stopped Yinlin Huina at the beginning happened to hear it, and said, "Mr. Zhou Teng is wearing a fluffy coat today, and a wool sweater inside. Huina specifically told him to wear it this way on the phone."

"Oh?" Youya raised his eyebrows, "Specially told?" This is a bit interesting.

"Yes," the woman didn't care about Yuya's attitude, and recalled with her finger on her chin, "I remember it very clearly, because Zhou Teng didn't like such clothes, and the two had a quarrel because of it!"

Yuya nodded thoughtfully: "Is that so, thank you."

Miyano Shiho whispered: "So, you think it's static electricity?"

Yuya nodded: "Yes."

"But, can static electricity really do it?"

Yuya touched his chin and pondered: "Of course, although the spark of static electricity is very small and only lasts for a moment, it is more than enough to ignite the gasoline that fills the garage."

Miyano Shiho nodded in understanding, but still had some doubts: "Even if the deceased has static electricity because he is wearing fluffy clothes,How can we ensure that the static electricity can be used as an ignition device? "

Yuya felt that Miyano Shiho's question made sense. As far as he knew, there were many ways to eliminate static electricity, most of which could be done easily.

So how did the murderer ensure this? What mechanism was used?

No, no suspicious items were found at the scene, so it should not be a mechanism.

Then it was words or hints?

Words... Thinking of this, Yuya stared at the woman again.

"Hello..." Yuya walked over and said hello.

"What's the matter?" The woman looked at Yuya in confusion.

Yuya smiled and said in a calm manner: "I have a few questions to ask..."

The woman took a step back with caution: "I have a boyfriend, no appointment. "

Yuya's mouth twitched: ...?

Miyano Shiho raised her eyebrows: ...?

Do I look like the kind of person who would just date someone casually?

She coughed hard and said, "You misunderstood. I just want to find out something about Mr. Zhou Teng and Ms. Hui Na."

The woman was stunned for a moment, then she noticed that there was another person next to Yuya. She immediately realized that she had misunderstood and smiled awkwardly; "Sorry, there are too many people who approach me on weekdays, so I unconsciously... So, what do you want to ask?"

Yuya thought for a while and asked, "You just said that they had a fight over the sweater? Can you tell me more about it?"

The woman smiled and said, "What's there to say? It's just a normal fight between young lovers... But if you want to know, I'll just tell you briefly."

"Don't we have a party here every weekend? I remember it was about three weeks ago? Ena suddenly asked Mr. Zhou Teng to wear a sweater when he came to the party, and asked him to drive an antique car. The woman pointed at the burned car, "Here, this is it."

Is the antique car that Yinlin Ena deliberately asked the deceased to drive? Youya's eyes narrowed slightly.

"But Mr. Zhou Teng doesn't like to wear sweaters, nor does he like that antique car. The reason for their first quarrel was that he didn't do what Ena asked. Ena was so angry that she poured red wine on his clothes on the spot."

"Then last week, Mr. Zhou Teng wore a sweater and drove an antique car, but the two quarreled again."

Youya raised his eyebrows, with a gossipy expression on his face: "What's the reason this time?"

The woman whispered: "Before Mr. Zhou Teng came to the party, he went somewhere else. Ena said that he didn't arrive on time and didn't care about her feelings at all, and the two quarreled again. ”

“They quarreled occasionally before, but these two times were the worst,” the woman shrugged. “It’s common, actually. Couples always quarrel. Besides, they are getting married soon, so it’s normal for Ena to be a little anxious.”

Yuya nodded slightly and said with a smile, “Thank you.”

“You’re welcome. If there’s anything else you want to know, just ask me!” The woman looked satisfied with her gossip.

Yuya smiled.

“How is it, did you get anything?” asked Shiho Miyano.

Yuya nodded, “I roughly understand it, but there’s something missing…”

“What’s missing?”

Yuya didn’t answer. He scanned the garage and soon stopped at the burned plastic barrels, which were used to store gasoline.

He thought for a while, walked to Inspector Yuminaga, and asked with a little doubt, “Speaking of which, although it’s not very safe to store gasoline in plastic barrels, it won’t leak gasoline, right? Did you find anything during the on-site investigation? ”

Inspector Yumio shook his head: "No, the plastic barrel was completely burned, and there was no trace."

Ginlin Ena suddenly said: "Maybe it's because of this child..."

Yuya turned around and found that she was squatting on the head of a golden hair.

"This child always likes to run around and has a bad habit of knocking things over..."

Hearing what Ginlin Ena said, someone immediately agreed: "So I said a long time ago, don't use plastic barrels to store gasoline, it's very dangerous."

The person next to him looked annoyed: "Who would have thought that the same thing would happen three times?"

"Three times?" Yuya suddenly looked at the man, "You said that the gasoline was knocked over three times?"

The man was stunned and replied: "Yes, last week and the week before, Zhou Teng found that the gasoline was knocked over when he came. Later, after finding out that it was Ena's golden hair, the two had a big fight. ”

“When we were arguing, we seemed to be talking about cars, clothes, etc…”

“Enough!” Yinlin Huina suddenly screamed, “Let’s not talk about those things anymore!”

The two people who were talkingStartled, he quickly shut his mouth.

Ginbayashi Ena stroked the golden-haired dog's head with a sad face, muttering: "This happened because he followed what I asked him to do. After all, his love for me is just this..."

Yuya squinted at Ginbayashi Ena, and suddenly said: "Although I don't know Mr. Zhou Teng and don't know what kind of person he is, since he put on a sweater and drove a vintage car as you asked this time, he must still have you in his heart."

"Is that so?" Ginbayashi Ena's expression was a little confused.

Inspector Yumio looked at the time and said: "Okay, since it is confirmed that this fire was an accident, let's stop here today."

"Wait!" Yuya raised his hand to interrupt him.

"What's wrong, Kamiya-kun?" Inspector Yumio asked puzzledly.

"Inspector Yumio, actually, I have a different opinion about this fire."

"What opinion?"

Yuya said slowly: "The forensic officer did not find the fire-starting device at the scene, right?"

Inspector Yumio nodded: "Yes, and I have confirmed everyone's alibi. When the explosion occurred, everyone was in the villa. Even if there was a timed fire-starting device, there are too many uncertainties when it is impossible to determine when Zhou Teng will arrive."

Yuya nodded: "That's true, but what if I say that there was actually a fire-starting device in this accident?"

"What did you say?" Inspector Yumio widened his eyes, "Where?"

Yuya turned around and slowly raised his hand to point to a place: "It's here."

"Ah?" Inspector Yumio was confused. Yuya was pointing at the body covered with white cloth. "You said the body was a fire-starting device, how is this possible?"

Others also looked at Yuya in confusion.

Yuya said calmly: "After the confirmation of the forensic officer and the testimony of the people present, Mr. Zhou Teng was wearing a sweater today, right?"

"Is that so?" Inspector Yumio looked at the forensic officer, who nodded quickly.

"To be precise, Zhou Teng was wearing a coat with a wool sweater today." The woman who just gossiped to Yuya added.

Yuya nodded: "Does Inspector Yumio usually wear a sweater?"

Inspector Yumio was stunned for a moment, then nodded and said: "Of course I wear it when it's cold, sweaters are still very warm."

Yuya said: "So, have you ever had that experience? When you take off your clothes at night, if you turn off the lights, you will see that kind of scene."

"That kind of scene?" Inspector Yumio thought for a moment, then suddenly realized, "You mean the static electricity that crackles when you take off your clothes?"

"Wait!" Inspector Yumio reacted immediately, "You mean, the source of this fire is static electricity?!"

Yuya smiled and nodded. Inspector Yumio is worthy of being in charge of arson cases, and he immediately thought of it.

Inspector Yumio touched his chin and pondered, "If it is static electricity, it can indeed ignite the gasoline in the garage. But isn't it common to have static electricity when wearing a sweater? What's the use of knowing this?"

"Hey, hey, hey, what are you talking about? Why don't I understand?" Someone shouted, and many people nodded in agreement.

Inspector Yumio couldn't help but look at Yuya.

Yuya touched his nose and said, "In this case, I will explain it to everyone."

"First of all, everyone should understand that wearing a sweater will cause static electricity?"

Everyone nodded. This is common sense, of course they know it.

"Mr. Zhou Teng was wearing a fluffy coat and a wool sweater today. When driving, people will inevitably have various movements and friction with the seat. In addition, with two sweaters stacked together, Mr. Zhou Teng has more static electricity than usual."

"When he drove to the garage, Mr. Zhou Teng got out of the car and locked it with the car key. When the key touched the metal lock hole, static electricity would occur, and crackling! Electric sparks appeared."

"At that time, the garage was already full of gasoline. The sudden appearance of the electric spark ignited the gasoline, duogang! All of a sudden," You also made an explosion gesture, "the garage exploded."

Everyone widened their eyes when they heard this.
