Maolilan skillfully caught Shiraishi and took him with him to ask the castle owner where he could rest.

After she left, after a while, Heiji Hattori still hadn't solved the mystery of the lawn chessboard.

Moreover, he had other doubts in his heart.

- Kudo has been gone for too long.

Heiji Hattori temporarily gave up solving the puzzle and ran to find someone.

However, after looking around, there was no figure of Conan on the entire floor.

Before, he thought that Conan had a clue and ran to study it alone.

But now that half an hour has passed, there should be a result.

According to Hattori's knowledge of Conan, if Conan hadn't found anything, he would have come back long ago and would have continued to check the lawn without incident.

And if he finds something, he will also appear in front of his teammates with a proud face and announce his results.

So now, what about people?

Thinking about it, Shiraishi, who had been very energetic all the way, suddenly fell asleep not long after he arrived at the castle. Although he also slept at Nagato's house, this narcolepsy seems to pick a comfortable place to have a bed on his own...... But other possibilities cannot be ruled out, such as a problem with the air in the villa.

Thinking of this, Hattori Heiji couldn't help but reach into his pocket and clench the folding stick.

…… This sleepy detective from Tokyo can't be some kind of prophet.

He said on the front foot that he didn't think the castle was right, and Kudo disappeared out of thin air, if he didn't think that these two people would be so boring, Hattori Heiji would have suspected that they were teaming up to play themselves.

By the way, Kudo seems to have said that Shiraishi has an almost weird intuition about crime, and can even prevent many murders that have not yet happened. It's a pity that now that people are asleep, they can't count on his skills.

Hattori Heiji looked at the quiet hallway, not intending to stay here any longer.

He began to look for the servants in the castle, intending to ask about the castle and by the way, to find out if there were suspicious people who might have abducted Conan.

There is a commission from Miyaman, and asking these questions will not arouse suspicion.

……

Corpses often harbor a lot of critical information, and the same is true for bones that have been weathered for years.

Conan in the secret passage soon discovered that the skeleton's foot bones were much thinner than those in other parts.

Combined with its approximate age and gender, Conan's mind conjured up the face of the old lady in a wheelchair he met when he entered the castle.

Thinking about it, the old woman did say something very strange.

——In the hall just now, when several people inadvertently mentioned the deceased old man, she sighed and said, "I have become accustomed to the days when he is not around, just like the pattern of the banknote and the size of the passport have changed, I will not get used to it at first, but I will get used to it after a long time, and time is terrible."

At first glance, this does sound a lot like the words of an old man who loves to tell big truths.

But according to the gardener, the old lady had been in the castle since she had a leg problem for more than a decade, and had never left the house at all, let alone traveled overseas.

And the size of the passport was changed six years ago, how can a person who has never used a new passport make such an analogy out of thin air?

Also, in the previous fire, the maids who served the old lady were burned to death along with the lady, but the old lady escaped, should it be ......

A terrible conjecture gradually flooded Conan's mind.

Before he could taste it, he suddenly had a heavy blow on his head, as if he had been pushed the head.

Conan didn't hold his ground, and fell forward on top of the skeleton, and almost at the same time, he heard the sound of bricks falling to the ground.

Conan raised his eyes slightly, and through the flashlight in his watch, he saw the "old lady" standing behind him, holding half a brick in her hand.

The other half cracked during the sneak attack and fell to the ground.

The "......" bricks are broken, and his head is okay?

Conan was confused.

Thinking about it carefully, the touch on his head just now didn't look like he had been knocked with a brick, and now, he didn't feel dizzy or headache, but it hurt to hit his jaw on the skeleton.

Immediately after, Conan's face itched, and he felt a few wisps of liquid running down his cheeks, and when it flowed through his nose, he could smell the obvious smell of blood.

Conan was even more confused, can this brick still have its own anesthetic effect?

He had wanted to touch his head to see if there was any wound, and at the same time get up and run away quickly, away from this dangerous "old lady".

But before that, Conan remembered the hat that the black cat had put on him not long ago, and the phrase "just because I didn't come".

…… If the black cat hadn't been here and hadn't given himself that strange hat, he would have been slapped on the head with a brick.

With such a lot of force, I should be dizzy for a while.

After coming to this conclusion, Conan closed his eyes and lay still on his stomach.

Nishikawa picked up the watch flashlight he had dropped, shone it on Conan's face, and was relieved to see that the child's head was covered in blood and his eyes were closed.

She stepped forward to carry the man, and with the other hand grabbed the skeleton wrapped in her clothes, and led them deeper into the secret passage.

After hearing that Mamiya Mitsumi had found two detectives, Nishikawa has been paying close attention to these people, trying to cut off the beard, snatching the treasure and then slipping away through the secret passage.

But now, the treasure was not found, and the bear child accidentally found the secret passage, and in such a big secret passage, so coincidentally encountered the corpse of the real old lady......

Nishikawa decided to wait for a few days for the child to starve to death, so she threw him into the woods outside, pretending that he had slipped into the woods for fun, slipped under his feet and fell and fainted, and then starved to death in the woods.

- It's not the first time she's done something like this, two years ago, a maid discovered the secret of the secret passage in the castle, and she also disposed of it like this, and Nishikawa Sami is very skilled at it.

As for the bear child's companions, they don't seem to be very old and have nothing to do. said that he is a detective, that is, his brain is a little smarter than ordinary people, and he should not be stalking about this matter.

But if they want to call the police, or find something wrong...... Then you can only kill them together.

Thinking so, Nishikawa came to the bottom of the secret passage, she threw down the skeleton, found another rope to tie Conan firmly, and returned to the castle from the secret passage, intending to continue to monitor the other three aliens.

She remembered that in addition to the child, there were two men and a woman.

The man who had been sleeping not long after entering the door should not have bothered too much - Nishikawa remembered that the gardener had almost called an ambulance when he saw the person suddenly collapse and could not understand the situation, so the little girl who was a high school student explained that her companion often fell asleep suddenly.

Nishikawa soon had a plan.

- Just put a drink next to Shiraishi and put some sleeping pills in it, and you should be able to solve it.

When people first wake up, they are easily thirsty, and when they are thirsty, they will drink water, and after drinking sleeping pills, they can continue to sleep...... So repeatedly, let him sleep until he left, it is not a problem. Anyway, no one else can tell whether he slept because he drank medicine or slept on his own.

High school girls are more timid, so they shouldn't walk around, as long as they scare her, she will stay in the room honestly. Even if she finds out the problem, the thin little arms and legs are not her opponents.

The only thing that was a little more troublesome was the very dark detective.

If he also finds the secret passage and enters the secret passage, then solve him in the dark, as long as he grasps the opportunity and lets go of the sneak attack, no one can withstand the knock on the head in the back.
