Hattori Heiji breathed a little relieved when he saw Shiroishi.

Even if this teammate is very unreliable, his combat effectiveness may suddenly become negative at any time... But if one more person can at least share clues.

Moreover, telling the situation you have mastered to another person is also a very effective summary and summary.

Moreover, judging from Shiraishi's current situation in advance, his role will definitely not be small when he is not asleep. With him, he might be able to find out the truth about the castle and Conan's whereabouts sooner.

Hattori Heiji briefly tells the story of what happened after Shiraishi fell asleep, especially Conan's disappearance.

Then he told Shiraishi his own speculation

"I think there are two possibilities. One is that Kudo witnessed a 'not supposed to see' scene, was arrested by someone who wanted to destroy him, restricted his movements, and even... it may have been killed.

"But what Kudo saw should have nothing to do with the treasure, and Mamiya Manta - we have said that we would not covet the property left by the ancestors of the Mamiya family. Mamiya Manta had no reason to attack us because the treasure was attacked.

"If others wanted to bypass the head of Mamiya and get the treasure, it would be difficult for them to think that a child could solve the mystery, and there was no need to kidnap Conan as a mental laborer.

"So at the beginning, I focused on the searches on the rest of the castle and those corners that are prone to hiding, but there was no clue... I had to contact the police and they would send people here, but it would not be possible to arrive at the early morning. Then I asked them to supervise the people in the castle and start a large-scale search."

Shiraishi nodded, thinking that the police community is easy to use.

He wanted to remind Hattori Heiji to ask his police friends to help bring a trailer so that he wouldn't have to drive the car back, just pretending to be asleep and get stuck in the police car.

But now Conan is missing. As a kind neighbor, he shouldn't focus on driving, so he had to swallow his words and continue to listen to Hattori Heiji's analysis.

"Another possibility is that Kudo discovered some secret passages or secret rooms - after all, it was a historic castle moved from abroad as it was, and it is not surprising that these installations are available.

"The mechanism is usually touched by a certain sound... By the way, I think the people of the Mamiya family do not know that there is a secret passage in the castle, otherwise Mamiya would have told us the relevant situation, which is more convenient to solve the puzzle.

"Of course, it may also be that there are shameful things in the secret passage. But in this case, most people will not specifically invite detectives to investigate in the castle.

“So I prefer that these mechanisms have been forgotten for a long time and have not been used by anyone for a long time—that is, the sound of its activation will only be greater.

"But before and after Conan disappeared..." Hattori Heiji suddenly glanced at Shiraishi, "Nearby, there was no other suspicious sound except you leaned against the door and accidentally knocked the door to the wall."

"So I thought at the time that Kudo might have triggered the mechanism in a farther place. But I searched all the rooms a little further on this floor, but I still couldn't find where the mechanism was."

"So I'm wondering now whether it was the movement you leaned against the door, covering up other sounds, such as Kudo's touching mechanism, which gave us the illusion that he had disappeared in 'silence'."

When I just thought of this, Hattori Heiji actually suspected that Shiraishi did it on purpose, after all, the timing was too coincidental.

But when I thought about it, I felt that I lacked motivation.

Kudo and Ran Mori seem to trust Shiraishi very much.

If Shiraishi wants to kill them, he just needs to find an opportunity to find out their itinerary, and then "meet" when they go out and make a successful plan, throwing people into the deep mountains and forests will definitely be much safer than adding such a variable to yourself now.

In addition, when Shiraishi made some noise, Hattori Heiji immediately looked back and checked.

He was able to be sure that Conan was not in the room at that time, and no mechanism in the room was closing.

After thinking about this, Hattori Heiji immediately came to this room, simulated Shiraishi's posture at that time, and leaned against the door. Then he searched all the walls within his field of vision, but failed to find any suspicious mechanisms.

...In other words, if the moment Shiraishi leaned against the door was really the time when the mechanism was triggered, then at that time, Shiraishi could not see Conan at all, nor could he master Conan's actions.

So this should be just a coincidence. Although this coincidence is difficult to encounter, it is not completely missing.

——Of course, as a science-focused detective, Hattori Heiji never thought that Shiraishi could actually report to him.

In short, after a series of brainstorming and trial and error, Hattori Heiji came to the conclusion.

——Conan should have disappeared near them, and the movements made when they disappeared were similar to the movements of the door hitting the wall. Otherwise, if the tone difference was too far, it would not be confused by the sound of Shiraishi leaning against the door.

With the guidance of ideas, when Hattori Heiji approached the room he had excluded from the beginning, he immediately discovered the problem after a moment of observation.

This room and the windows in the next room are all built against the wall.

But looking at the outside, you can find that the gap between the windows is too large - there is probably a secret passage in the middle.

Thinking of this, Hattori Heiji immediately understood.

No wonder Conan immediately discovered the problem. At that time, Hattori Heiji was busy talking to the employees. Conan ran in front himself, listening while looking for a window that was convenient for observing the yard.

Hattori Heiji didn't think much about it at that time, and followed Conan directly into the target room, so Conan's observation of the window was much more detailed than that of him.

——I asked myself for some remedy, and Hattori Heiji felt much better. He walked to the next door and began to look for possible mechanisms where he could hide it.

He soon noticed the decorative frame on the wall and the clocks above the frame.

I took a closer look and saw that there were several dragging fingerprints on the transparent cover. It seemed that someone had grabbed it in a panic and didn't catch it.

Hattori Heiji couldn't remember what Conan's fingerprint looked like, but after he compared it slightly, he felt that this size was indeed left by a child.

"It should be that." Hattori Heiji and Conan had a very consistent thinking. While talking about the situation with Shiraishi, they began to turn the pointer.

After turning back to 12 o'clock, the mechanism on the wall flipped again.

Shiraishi raised his hand and used some force to support the turned wall.

Hattori Heiji also raised his hand and pushed it on the wall, feeling the weight, revealing a "very sure" look

"He should have disappeared from here. This kind of force is indeed enough to bring a child into it... But after such an accident, he didn't knock on the wall, reminding us that we were obviously next door."
