There is a piece of writing engraved on the side of the staircase, which is drawn out with a sharp object, and the handwriting is hideous, and Hattori Heiji even subtly sees a little despair from it:

[That man is pretending to be me to seize the treasure in the castle......]

The last word is not engraved, but it is enough to express the meaning of the letterer.

Hattori squatted down and carefully observed the few lines.

There is a lot of gray on the words, indicating that these words have been around for a long time. And to spend so much effort to leave a handwriting in such a place shows that the person who carved the inscription could not leave, and may have been imprisoned here.

If you pretend to be a writer, you can take the treasure...... This indicates that the person who left these words was not of low status, and was probably the owner of the castle.

But when Hattori was looking for Conan just now, he didn't forget to collect clues in the castle - this family is scarce, and if there is really a major event of a certain master being kidnapped, there will definitely be some rumors.

But Heiji Hattori had never heard of anything like this.

His gaze stopped at the word "fake" on the wall, and suddenly a chill ran down his spine.

…… Perhaps the original owner had been replaced in some way, so the other helpers didn't know anything about it.

The means of substitution are nothing more than plastic surgery and transfiguration.

Short-term deception, you can use disguise.

But most of the people in this family are dead, and the few people who live in the castle are still living in the castle. Judging from the idea of lettering, the "fake" that lasted for so long is more likely to be plastic surgery.

…… So who exactly got replaced?

It's more likely that Miyaman's stepson is more likely, his parents have passed away, and no one is familiar with him.

But thinking about it this way, neither the palace and the old lady are too familiar with anyone.

Also, is it possible that there is a deceased lady? For example, someone suddenly found out that his wife was replaced, and set fire to it in anger, causing the counterfeiter to also die in that fire?

Wait, mention the fire......

Just as he was thinking about it, Bai Shi's slightly shocked voice suddenly came from behind him: "Look at this." ”

Hattori was stunned and ran over quickly.

Shiraishi is not the type who likes to be surprised, and combined with the previous experience of finding mechanisms, what can shock him must be some very useful clues.

Sure enough, Hattori Heiji looked over along Shiraishi's direction and saw a small clump of white thread.

He squatted down, and under the complicated gaze of Shiraishi next to him, he picked it up and twisted it professionally, and came to the conclusion: "It should be hair." ”

The hairs had begun to rot, and they were also covered with a lot of dust, and they were horribly dry, like the hair of a dead man.

But the break is relatively new, as if it has just been broken.

Combined with the very old color of his hair, Hattori Heiji immediately circled a person in his conjecture just now - the old lady.

Before, although he also included the old lady in the list of suspects, he felt that this possibility was not too high. 127

If you want to imprison a person, even an elderly person with inconvenient legs and feet, it takes a certain amount of strength, and it is difficult for peers to operate. Moreover, there is a risk of transmissibility, and many clinics may not accept elderly patients.

- In other words, the impostor should not be an old man, but a little younger.

So, who would want to have plastic surgery to be an old lady, huddled in a wheelchair every day, and pretend to be Alzheimer's.

Even if it is for money, compared to young looks and freedom, is a treasure with uncertain content really that important?

However, the hair in front of him shows that the truth can indeed be so absurd.

This made Hattori Heiji a little puzzled - could it be that this impostor already knew the contents of the treasure and decided that it was a treasure that could cost him his youth, appearance, and freedom?

“…… The brain circuits of these prisoners are really difficult to figure out. Hattori Tossed the clump of hair away, pointed to the inscription he had just looked up on the back, and told Shiraishi what he had speculated.

"I see." After hearing this, Bai Shi nodded, and also began to "reason", "Since she is pretending to be an old lady with inconvenient legs and feet and likes to stay in the room, she should have a lot of free time." From the surroundings......"

He shook his flashlight around, illuminating the path, and continued:

"There must be more than one entrance to this secret passage. It is possible that the old lady's use of these secret passages has always been used to get in and out of the castle.

"Today, she found out that Mr. Mamiya had let outsiders in, and she was vigilantly following us, and then she found out that a child had entered the secret passage...... In this case, it is possible that Conan was captured by her. Shiraishi tried to steer the situation this way.

And it's not lying, it's actually the truth.

"Yes, but she has been able to disguise herself for so long, maybe she has other helpers in the castle, and there are too few of us." There wasn't much that could be played, Hattori Heiji added in his heart, and continued:

"I've already contacted my dad's colleagues before, and when they come, let's start a mass search."

As he spoke, he glanced at his phone: "Now we have to find the exit first, the underground signal is too poor to contact them." ”

Shiraishi has no objections.

On the way to find the exit, the two of them chatted briefly, and Shiraishi took the opportunity to quietly spoil the idea that Hattori Heiji had a prototype to piece together completely.

Hattori's curiosity was satisfied, and he finally began to think about the meaning of the chessboard again.

Shiraishi also needs Hattori Heiji to send information to the "old lady".

He said thoughtfully: "I think the hidden information in the chessboard may have something to do with that old man." ”

Shiraishi actually only remembers the results, and doesn't quite remember why it is related.

But a young detective like Heiji Hattori who is competitive and wants a lot of face shouldn't be like a joker like the Twilight Police Department, who immediately comes over and asks "why, why", and he will think for himself first.

In terms of setting, Conan and Hattori Heiji's reasoning ability is not much worse.

In the original world line, Conan didn't get any hints, and he was able to come up with an answer after spending a while, and it didn't make sense that Hattori couldn't think of it when he heard the hint.

Of course, if he really can't think of it, and chooses to put down his face and ask Shiraishi a question because he is worried about the safety of his companion, Shiraishi plans to say, "Judging from the description of the maid and Mr. Mamiyaman, that old gentleman is a *%*#@的人" - here to paraphrase a few unclear technical terms, conduct a messy personality analysis, and finally say that the code set by the old lady is likely to be related to himself.

Fortunately, Heiji Hattori didn't let him spend his tongue.

The Western high school detective really began to think about it on his own, and after a few minutes, he punched it into his palm and suddenly realized: "So that's it!" ”
