Conan: The Mechanic

When Kogoro Mori left in front of Hotaru, who was leaning against the window sill at the end of the corridor on the fourth floor, his expression was serious.

Maori Kogoro may often make mistakes in reasoning, but it doesn't mean that he doesn't want to know the truth - especially the truth of the question asked by such a beautiful girl to him.

At this moment, Mouri Kogoro suddenly realized that something was wrong. "?"

Just in front of the Okazaki Sumie's house, there seems to be something very strange. Mouri Kogoro immediately crouched down and looked at the trace.

This is an arc extending from the door frame, with a rotation angle of about 40 degrees, which looks like a trace left by something at the bottom of the door.

Wait a minute, how does this look like...

Mouri Kogoro thought of something in his mind, and immediately looked at the bottom of the door. After observing for a few seconds, he touched the door panel where the traces indicated that the things at the bottom of the door were located with some surprised eyes.

His hand directly pushed that part of the plank in, revealing a trap with a rolling ball inside.

Mouri Kogoro's expression instantly became subtle.

He had heard of this mechanism before. It was a surveillance mechanism—as long as it was installed on the door, it could detect whether the door was opened through the contact between the rolling ball and the door frame.

If someone is really monitoring him... This kind of mechanism is limited to its miniature size, and the signal strength of the signal transmitter inside the mechanism is very poor. If you want to receive the signal of this kind of mechanism, you must install a signal receiver or relay nearby. device. And the device itself means...

Mouri Kogoro looked straight up at the top of the corridor—a black spot was clearly visible at the top of the corridor.

A few meters away, another black spot is also clearly visible.

These black spots are nothing but the supporting signal transmission device.

Taking a few steps forward, Kogoro Mouri stood under the last little black dot and looked at the door on the right.

In addition to signal strength, this small signal device has a drawback - small size means small battery, which means very poor battery life, which means that this monitoring tool is only suitable for its own neighbors. , otherwise it will be troublesome to change the battery only every few days.

So, it's basically this one, right? The monitor who installed these monitoring tools.

……

"Who is it?" The unshaven head of the household opened the door and looked at Kogoro Mouri suspiciously. "Excuse me, what's the matter with you?"

"My lord, Kogoro Mouri, is a detective invited by the Osaka police." After observing the eyes of the head of the household and confirming that his first reaction was confusion, Kogoro Mouri chose to brag. (This first look basically means that he is not a murderer, so Kogoro Mouri doesn’t have to worry about stunning snakes, and he can say whatever he wants.) “I want to know, the steel eyes on Miss Okazaki Chengjiang’s door are you put on, right?”

The steel eyeball is the common name for the rolling ball monitoring device. Only professionals who are very familiar with these things will know the meaning of this term.

"Do you have any evidence?" The head of the household denied it after a moment of astonishment. "If there is no evidence, I-"

"I don't care about these things, it doesn't make any sense for you to pretend to be garlic with me." Kogoro Mouri waved his hand, and took out a sealed bag - which contained steel eyeballs taken from Okazaki Chengjiang's door. "I can give it to you even if you don't promise to reveal this, I just need some help from you - we suspect someone is doing something illegal through your surveillance device."

Hattori Heiji had already told her about the strange thing that there was only a two-minute interval between Okazaki Sumie's two phone calls, so it was obvious that someone could monitor Okazaki Sumie's every move here.

"..." The head of the household hesitated for a few seconds, and then offered his own conditions. "If you promise I won't be implicated, then I'm willing to tell you these things."

"Deal." Mouri Kogoro nodded and handed the sealed bag to the head of the household. "Now, let's talk."

……

The statement of the head of the household is quite simple-one night when he was changing the battery of the steel eyeball, he was found by a person, and that person threatened to expose him, forcing the head of the household to provide the person with the record of Okazaki Sumie's going out. Just now, he used this power and asked the head of the household to call him immediately when the door of Okazaki Chengjiang was opened.

"Don't you know that person?" Kogoro Mouri asked.

"Yes," the head of the household nodded hastily. "I don't know who he is at all, just his phone number."

"Let me see." Kogoro Mouri demanded.

After transcribing the number from the landline, Kogoro Mouri continued to ask. "When did you find out that Okazaki Sumie went out?"

"It should be the time of the call, which is 1:09." The head of the household replied.

"Okay, let's do this first," Kogoro Mori nodded. "Then if anything happens, you can contact me again. My mobile number is—"

"Wait a minute~www.readwn.com~ Are you sure you won't sue me or something?" the head of the household confirmed. "I really just like playing radio, so I'm trying to mess with this..."

"To be honest, I don't quite believe this lame excuse you used," Kogoro Mori frowned at the head of the household, but his expression softened after a while. "Be a good person and stop doing such nasty things."

Saying that, Mouri Kogoro took out a cigarette from the cigarette case in his arms and handed it to the head of the household. "I just saw the cigarettes you usually smoke. I'm a little better. Let's have one."

……

Mouri Kogoro was walking along the sidewalk of the highway next to the Xidu apartment, while thinking about whether there were any breakthroughs in the existing clues, while observing the roadside.

The murderer used the radio amateur just to determine the whereabouts of Okazaki Sumie, and this is obviously to make up for the fact that he is not around here. Considering that the decision to eat at this restaurant in Shinsaibashi before and even park the car at that place was decided by Officer Sakata, Officer Sakata is obviously very suspicious in this case.

However, when Hattori Heiji and Conan jumped out of the car, Sakata Mingming was still stuck in the road, and it took a long time to get there by car-their car passed there just now, and it was confirmed that this place is really very congested, if not If it takes more than 15 minutes, it is impossible to bypass that section of the road with heavy traffic jams. How did he get to the public toilet before Hattori Heiji and Conan got there, and then kill Ms. Okazaki Sumie?

At this moment, Kogoro Mouri suddenly noticed that the main road ahead seemed to have a ramp leading to the side road, and there seemed to be a small alley not far in front of the ramp.

Although this alley is not paved with asphalt, it seems to meet the requirements of traffic in terms of width?
