There was no one in the stairwell, which was great for phone calls.

However, Conan's phone rang just when he arrived.

It was Kaedehara who called.

"The doctor is worried and wants to know the latest situation," Kaedehara glanced at Dr. Asasa who was listening to the phone together, "That guy is calling again?" ”

"Hmm." Conan replied, repeating what the bomber had said, and then telling everything else he had learned from the Twilight Police Department, "How's it going, Kaedehara, do you have any ideas?" ”

Retelling it was a rearrangement of ideas, and Conan vaguely felt as if he was about to catch something, and he was just a kick away from the answer.

But the last kick is often the hardest.

Kaedehara, who was on the other side of the phone, was silent for a moment.

Although he did not remember the specific details, he still had some impressions of the general framework of the incident. These impressions also correspond to reality as things develop.

He was also able to connect with many known clues, so by the time Conan was halfway through his speech, he knew the answer to the question with half reasoning and half prescience.

However, he didn't want to put on the character of a prophet, and he didn't want to undermine Conan's confidence too much, so he pretended to think for a while before saying in an uncertain tone: "Between the rails? ”

It was as if a bullet was passing through his brain, and Conan figured it out at once.

"If you don't defuse it before sunset, the bomb will explode, so I thought of light," Kaedehara explained, "and I guess there should be a sensor on the bomb." If you don't receive light for a while, the bomb will explode—"

"And if the speed of the train is less than sixty kilometers per hour," Conan continued, "the sensor device will be blocked by the train and will not receive the light for more than the preset time, which will also cause an explosion - thank you, Kaedehara!" Great help! ”

Conan hurriedly hung up the phone and went back to find Heiji Hattori.

Kaede Yuan was a little helpless, and his words were not finished yet.

Still, that's fine.

On the other hand, Heiji Hattori, who learned the answer from Conan, was a little depressed that he had lost the reasoning again, but he still cheered up and went to the Twilight Police Department with Conan.

Based on the results of reasoning, it is only necessary to retrack the train to a different line to avoid the bomb and stop the train.

Soon, the first train selected for testing changed tracks, entered a new line, and then gradually slowed down.

60 km/h.

59 km/h.

58 km/h.

There were no explosions.

The dispatchers cheered and then quickly threw themselves into the dispatch of other trains.

Officers also went out in large numbers, hoping to find all the bombs and defuse them before sunset.

Since the reasoning didn't take long, they were able to complete the task ahead of schedule.

Heiji Hattori and Conan, who had been in the Metropolitan Police Department, also sensed the good news from the movement nearby.

"Whew, it's time to finish." Hattori stretched his body.

"There are still prisoners who haven't been found." Conan said.

"If you want me to say," Hattori Heiji bent down to look Conan in the eye, "You might as well call and ask your new brother directly, see who he has offended recently, and you have to trouble him." ”

It's best to give me the phone.

Heiji Hattori added in his heart, and then found Conan staring at him all the time.

Hattori Heiji was stunned for a moment, and then laughed angrily, "Hey, you guys shouldn't be suspicious of me, right?" ”

"Haven't you been making trouble with Shinichi's brother?"

"Can that be the same!" Hattori's face darkened, "I just want to meet that nasty boy!" Besides, isn't there the same one as me, the one named Teiji Moriya? Not only did that guy invite Kudo to tea, but he kept asking his woman about him—"

Conan froze.

Hattori Heiji was also stunned.

“… You can't just suspect Kudo just because he wants to see him, right? After a while, Hattori held back a sentence.

"Aren't you too." Conan gave him a blank look, "However, speaking of which, the house of the Kurokawa family, which was set on fire before, was also designed by him..."

"What else?"

“… Nope. ”

The reasoning seemed to have reached a dead end again, and at this moment, Officer Shiratori, who had short hair and half of the coral-shaped bangs on his side, walked over with a relieved smile on his face, "Mr. Hattori, Conan, thank you very much-"

"Officer Shiratori!" Hattori Heiji said solemnly, "You said before that it's called..."

"Kurokawa." Conan reminded.

"Yes, Kurokawa. The Kurokawa family's house was burned, right? ”

Seeing that the duo was so serious, Officer Shiratori also withdrew his smile cooperatively: "That's right, there is also a series of arson cases, and we suspect that the same person did it." ”

"Were these houses all designed by Teiji Moriya?"

Officer Shiratori was stunned for a moment, then replied, "That's right. ”

Hattori Heiji glanced at Conan triumphantly.

Conan ignored him, and instead asked Officer Shiratori, "And where were all the bombs planted today?" ”

"Oh, I was just going to tell you about it." Officer Shiratori looked at the two, "Four of them were placed near the residential area, and one was on the bridge, the Sumida Canal Bridge. ”

"Sumida Canal Bridge?"

"Well," Officer Shiratori said with a strange expression, "if you're trying to ask if this is also Mr. Moriya's design... And that is, indeed. ”

"The bridge was built in 1983," Officer Shiratori continued, "and it was not an iron bridge, but made of English stones, which caused a lot of talk at the time. Teiji Moriya also won the Best Newcomer Award from the Architectural Association of Japan for the design of the bridge. ”

Officer Shiratori couldn't help but show off his architectural knowledge, and then found out that this belonged to playing the piano to the cow.

I saw Hattori Heiji say to the elementary school students, "I won this time", and said to Officer Shiratori, "I suspect that these bombings, and those arson cases," Hattori Heiji deliberately paused, "It's all related to Teiji Moriya." ”

Conan thinks so too.

Whether it was intentionally targeting Emperor Moriya, or what Emperor Moriya did, in short, I had to meet Emperor Moriya now.

However, Conan always felt that Officer Shiratori was a little weird.

After Heiji Hattori finished telling his reasoning, Officer Shiratori muttered, "It seems so." So it could be that someone is deliberately targeting Mr. Moriya? ”

"Or it could be—"

"Then we'll have to protect him!" Officer Shiratori said.

Belch... Seems to work too?

Heiji Hattori, who was interrupted, didn't care about this, and it was more appropriate for him to reason in front of the prisoner.

And there is no conclusive evidence for his reasoning now, so I just went to Moriya's house to have a look.

Thinking like this, Heiji Hattori planned to go with Officer Shiratori.

Officer Shiratori, of course, would not refuse.

"Officer Shiratori," Conan asked duly, "where's the Twilight Police?" ”

"The bomb has just been defused, and he still has a lot of work to attend to at the Twilight Police Department," Officer Shiratori looked at Conan, "I'll just come with you." ”

Conan nodded cutely, then thoughtfully.

He has handled countless cases in Rice Flower, and the number of times the Twilight Police Department has not been by his side is only a handful.

Soon, Officer Shiratori took a few of his subordinates, along with Hattori Heiji and Conan, to the Moriya House.
