At some point, a cake shop opened on the corner of the street, called SMW6, which seemed to be a chain store.

Odd name, at least that's what she thought.

But out of curiosity and love of food, I wanted to try it. And I was a little curious about why it was so late and the store was still open.

Just as he was about to push the door in, he suddenly heard someone shouting outside.

"It's on fire, is there anyone who can help me?"

It was an anxious male voice, sounding very young.

Qinghai Chuantang walked over to find a sound, only to see a few bags of garbage had already ignited a flame. But fortunately, the fire was not very fierce, because it had only been ignited for a short time.

She walked to the store, found a jug of ice water, took it and ran quickly to the door, poured it on the fire, and the fire was immediately stopped.

Qinghai Chuantang looked at each other, his face a little speechless.

He looks like he's only in his early twenties, and he's more immature like a high school student. The pupils are purple, and she has short pink hair with slightly upturned ends, which makes her look a little cute.

"How old are you? Such a small thing is so panicked. ”

As soon as the words of thanks reached his mouth, they were swallowed back, replaced by his apologetic look and tone.

Seeing that he looked a little aggrieved, Qinghai Chuantang inexplicably felt a sense of guilt. But soon, this feeling disappeared, and I had another thought in my heart: I wanted to ravage him......

Qinghai Chuantang coughed lightly, "I'm sorry, I shouldn't have said that." ”

With that, she looked up, then took out a pair of gloves from her bag and put them on. Then, she crouched down and picked up the plastic bottle on the floor, which still contained some colorless liquid.

She put it in front of her nose and sniffed it.

"It's acetone, it's strawberry."

"Huh?"

Akakawa Aoi blinked, looking a little puzzled.

"Although the cap is opened, the probability of a burning cigarette butt flying next to the acetone bottle that has not yet fully volatilized and hitting the ground is not high. It was a deliberate arson, not an accident. ”

Akakawa Aoi nodded as if he didn't understand, and then looked at her, his tone was a little curious: "But, may I ask who you are?" ”

Qinghai Chuantang put things back in their place, and then stood up.

"I just saw that the shop was still open, so I wanted to buy a cake and go back. I didn't expect to encounter such a thing. ”

"Are you going to buy a cake?"

Akakawa Aoi smiled happily, as if she had received some great reward, and she saw a feeling of "happiness". "I'm the manager of SMW Cakeshop. Why don't I treat it as a reward? ”

Qinghai Chuantang hesitated, "This is not very good, right?" ”

Then, after a moment's notice, he continued: "A tiramisu, thank you." ”

Authentic tiramisu is always paired with Marsala.

Things don't end there.

The next day, the police received several more reports, all of which were related to arson, which fell under the jurisdiction of the Search Section.

Of course, sometimes there will always be detectives involved.

"The smell...... It's acetone! ”

"If acetone is vaporized, even a small flame will catch fire."

This is a temporary installation. When acetone gasification burns, I escape to find time.

"That's what the guest who came that day said the same."

Sera and Conan looked at him together, "Customer? ”

Akakawa Aoi nodded, "Yes, I helped put out the fire that day." ”

Shira Zhenchun rubbed his chin and thought, "Sometimes, arsonists will also appear at the arson scene to extinguish the fire. ”

Conan hurriedly asked, "Big brother, do you remember what that customer was wearing?" ”

"Well...... Akakawa Aoi scratched his head, his face a little red, "Let me think about it, after all, my memory has always been not very good." ”

"Long black hair with a ponytail. He wears a black base layer and a white hooded jacket. ”

A voice suddenly appeared behind the two, getting closer and closer.

Qinghai Chuantang met their eyes in time, and couldn't help but be slightly stunned, and couldn't help blurting out: "No one had an accident, right?" ”

If it was just that Shiliang was innocent, she didn't think it was anything. But as long as Conan is at the scene, he will always have a preconceived idea of whether there is another murder.

"Fortunately, there were no casualties. Although it is not a fire, there have been several similar cases recently, indicating that ......"

Before Sera Zhenchun finished speaking, Conan couldn't wait to answer: "It shows that this is a serial arson case!" If you don't find the culprit quickly, it may cause casualties! ”

Perhaps there will be more serious consequences.

Because this thing is addictive.

Akakawa Aoi stared at him, then blinked, his expression was slightly surprised: "Although you see that you are quite small when you go up, the tone of what you spoke just now is more like an adult." ”

Conan reacted to something, sneering and scratching his head, "No, these are all taught to me by Uncle Maori. ”

"Maori? Do you mean that famous detective, the sleeping Kogoro? I didn't expect you to be related to Mr. Maori, no wonder you became so under his influence. ”

Although it was a compliment, Conan was not happy at all, and the corners of his mouth twitched: Those cases were actually solved by me, okay?

"Speaking ......"

Aoi Akakawa seemed to have something in mind, "In addition to the No. 6 store, the No. 5 store also suffered from the same problem. I was hesitant to settle the matter with Mr. Maori. But on second thought, Mr. Maori is such a famous person, and he can't even think of it to solve a small case like mine. ”

The cakes in SMW Cake Shop taste very good, and in terms of price, they also taste the same as it, but there are many people who like it. If it is because of this, the other party is jealous, so it seems to be expected that he wants to destroy SMW.

"This kind of trivial matter, don't bother the detective to come out. Don't look at me as just a high school student, I'm also a detective and solve a lot of cases. Right, Conan? ”

As he spoke, Sera looked down at him and smiled.

"Huh? Ah, yes, yes. ”

At first, Conan didn't react in his contemplation. After that, when I heard Shiliang Zhenchun calling herself, I was inexplicably nervous, so I answered "yes" casually, but in fact, I didn't know what the other party said before.

Akakawa Aoi showed a happy expression, "That's great, please help find the real culprit." ”

Helping the cake shop find the arsonist, but also helping the rest of the victims who had similar experiences. Even if Akakawa doesn't say anything, they will continue to investigate, and then find the arsonist, and they will never let him go unpunished.

"By the way, I have a map in the store, maybe I can help a little."

With that, Aoi Akakawa pulled the door open and made a "please" gesture.

Based on information published on the Internet, Sera Masumi has circled off the locations where the arson cases occurred, mainly in Haraeong Road and Seongcheon Road.

"The prisoners set fire at the same time. In the afternoon, it is Hara Ei-do, and in the evening it is Seongcheon Road, but it is very quiet during the day. ”

Conan touched his chin and thought, "In this case, the prisoner should be an office worker." ”

"Arson on the way home from work. Because it's a temperament that does it with the mood, there may be a lot of arson that hasn't been reported. Judging by the modus operandi, it should not be a rigorous character, but just acting according to the mood at the time...... A simple character who will not regret or look back. Male, early thirties, unmarried. ”

Seliang Zhenchun looked up at her and said with some surprise, "Why do you know so clearly?" ”

Qinghai Chuantang remembered that she hadn't told the other party her identity.

So he simply introduced himself: "Qinghai Chuantang is a profiler. ”

"Shiliang is pure."

A certain memory before, in the unwitting hypnosis of Qinghai Chuantang, has been hidden. As long as you don't get too much stimulation, or take the initiative to untie it, the other party won't think about it.

"From the original Rongdao bus station to the Seongcheon-do bus station, there was nothing, and it was very quiet. But between the bus station and the subway station, there was an arson case...... It shows that the prisoner lived in Seongcheon-do and took a bus to work in Wonyeong-do. ”

I got off work between 6 p.m. and 6:30 p.m. and stayed on Seongcheon Road. Then, if you look for the person who bought the cigarettes and acetone in the vicinity of Seongcheon Road, you may be able to find the prisoner.

Convenience stores, supermarkets, cosmetics stores...... As long as the ingredients contain acetone, they need to be checked one by one.

"By the way, and the pharmacy." Seeing everyone staring at him, Akakawa Aoi smiled a little shyly: "Because it's very useful for kitchen descaling, I sometimes go to the pharmacy to buy some back." ”

"Ahh

Conan seemed to have noticed something, pointed to a certain place and said, "SMW5 ignited at four or five o'clock, during the day." If you follow what the big sister said before, it should be at work, how can you commit a crime? ”

Seliang Zhenchun didn't think it was strange, "If something unexpected happens, it's actually very understandable. For example, rest days, leave of absence, monthly leave. ”

"It's possible...... Big sister, are you going to catch the prisoner with us? ”

As he spoke, Conan looked up at Qinghai Chuantang and showed an innocent smile.

Qinghai Chuantang stared at him with strange eyes, which made Conan feel a little inexplicable and puzzled.

"Isn't it the criminal police's business to catch criminals or something?" Then, after a momentary change, he added, "However, if you want to go to SMW No. 5, I can give you a ride." ”

If you are walking, you will have to walk for an hour or two, but it is much more convenient to take a car. It takes no more than 20 minutes to drive from shop 6 to shop 5, which greatly reduces the time consumption.

As the saying goes, time is money.

So, they didn't say no.

After arriving at SMW5 store, Shinsumi Sera and Conan inspected and searched the fire spot.

"This cigarette butt was just lit ......"

There's a long section left.

The cigarette butts in SMW6 store were discarded after being smoked.

"Perhaps, there is more than one prisoner."

Conan's gaze became determined.

It seems that the arsonist of SMW5 store imitated the modus operandi of the former.
