Kitajima Shingo seemed particularly nervous. When he asked about Suzuki Sonoko's situation, his hands involuntarily moved his hands on Suzuki Sonoko's back, as if comforting a child.

"Teacher, please don't touch me, it will make you want to vomit even more."

After shaking off Kitajima Shingo's hand, Suzuki Sonoko said feeling slightly uncomfortable.

"Then, go to the lounge and lie down for a while. It will feel better."

At this time, Nantian Kyousuke stepped forward and suggested, "Kudo-kun, can you help me?"

Kudo Shinichi nodded in agreement, so Minamida Kyousuke and Kudo Shinichi helped Suzuki Sonoko to the lounge in the cabin, while Mao Lilan, Nishida Mai and Kitajima Shingo also followed them to the lounge.

"Thank you, Mr. Nantian."

Lying down on the bed in the lounge, Suzuki Sonoko said in a slightly infatuated tone.

"Ah! Seasickness medicine!"

Mao Lilan on the side looked at Suzuki Sonoko's condition, began to rummage through her pockets, and then said helplessly, "If only I had brought it!"

"It doesn't matter, I brought it with me!"

At this time, Nishida Mai took out the seasickness medicine from her backpack and said, came to the bedside and handed the medicine to Suzuki Sonoko.

"Thank you, Miss Mai."

After taking the medicine, Suzuki Sonoko said calmly.

"You're welcome, this is my job."

Nishida Mai said, at the same time, Minamida Kyousuke handed Suzuki Sonoko the mineral water.

"Really, why does the young lady who rides the family speedboat all day get seasick?"

Kudo Shinichi said from the side.

“The family speedboat!”

Hearing this, Minamida Kyousuke and Nishida Mai were very surprised.

"Don't look at Suzuki-san like this, she is the eldest lady of the Suzuki Foundation!"

Teacher Shingo Kitajima explained from the side.

"What does it mean to look like this?"

Regarding the teacher's words, Suzuki Sonoko, who had just taken the medicine, was a little unhappy, and then looked at Minamida Kyousuke, "Mr. Minamida, you will always stay with me, right?"

"Well, I still have a job!"

Nantian Kyousuke said in embarrassment.

"We are with you in the garden!"

Mao Lilan pulled Kudo Shinichi and said.

As a result, Minamida Kyousuke, Nishida Mai and Kitajima Shingo left the lounge with peace of mind and went to do their own things.

"Ah... Mr. Nantian is gone."

Slightly disappointed, Suzuki Sonoko said.

"Garden!"

Xiaolan sat on the edge of Yuanzi's bed and gave an angry advice.

"Okay, okay, don't be angry!"

Seeing Xiaolan's disgust with her behavior, Suzuki Sonoko couldn't help but said with relief, "As for me, I'll be fine alone."

With that said, he leaned into Xiaolan's ear and whispered: "At least make some happy memories with Shinichi!"

"Are you really okay?"

Xiaolan asked, "You have to be obedient!"

"Okay, let's go!"

Urging, Suzuki Sonoko said.

So Xiaolan pulled Kudo and left the lounge. However, before leaving, Kudo told Suzuki Sonoko: "Sonoko, lock the door. Except for me, don't open the door when anyone comes!"

Suzuki Sonoko was a little confused about this, but still did it.

The above is what happened on the ship.

What happened next is what Takato already knew - when the boat was near Hakone Shrine, and the tour guide Mai Nishida was introducing the origin of Hakone Shrine to the students, there was a sound of water falling from the stern of the boat. At that time, Kudo Shinichi took the lead and ran away.

He went to the stern to check, and Mao Lilan followed closely behind. As a result, he saw Suzuki Sonoko's headband on the lake behind the stern.

So, everyone ran to the lounge where Suzuki Sonoko was, and found that the door to the lounge that was supposed to be locked was opened. Then, they searched everywhere on the ship, but could not find Suzuki Sonoko.

"Afterwards, the tour boat docked and called the police. The police found the suspected criminal's diving suit and oxygen bottles in the nearby woods."

After Kudo Shinichi finished telling what happened, he explained the subsequent discovery, "But just now, I started looking near the torii of Hakone Shrine until I found the place where the diving suit and oxygen bottle were found. From the map, this distance

It’s really too far.”

"That's right, the prisoner did not escape by diving."

Gao Yuan said, pointing to the railing at the stern of the ship and said, "There are traces of being burned here. If you guessed correctly, the sound of falling into the water you heard at that time should be a mechanism designed by the prisoner. For example, he tied it here with a rope in advance.

A heavy object is then installed with a small ignition device. When necessary, the prisoner's control mechanism burns the rope, and the heavy object will fall into the water, creating the illusion that someone jumped into the water at that time."

Hearing this, Kudo Shinichi came over and touched the outside of the railing with his hand, and finally touched a trace of black substance remaining after burning.

"it is as expected."

Kudo Shinichi agreed.

"Then it is obvious that the prisoner should have activated the mechanism while you were all listening to the tour guide's explanation and staying on the front deck of the ship. In other words, the prisoner is indeed a person on the ship, and the disappearance of Suzuki-san must have occurred in

Before this.”

Gao Yuan said, "Under the circumstances at that time, it was impossible for the prisoner to take the person away from the boat, so he should just hide the person on the boat..."

Hey, wait a minute, if you put it this way, is this method similar to the method used by Nakagawa Moemi to kidnap Suzuki Sonoko in Teidan High School: At that time, Nakagawa Moeme made people think that Suzuki Sonoko was taken out of the old school building.

But in fact, she only temporarily hid the person in the old school building. It was just that she saw through Nakagawa Moemi's tactics in advance and did not let Suzuki Sonoko really be kidnapped.

"But, we checked everywhere on the ship, and we couldn't find the garden anywhere!"

Xiaolan said anxiously, "Right, Shinichi!"

"That's right, I searched everywhere, and I really didn't find the garden at that time."

Kudo Shinichi said.

"In that case, take me to the lounge first and take a look."

Gao Yuan said.

So, Kudo Shinichi and Xiaolan took Gao Yuan to the lounge in the cabin. At this time, the door of the lounge was not locked.

Walking into the lounge, using the light of Kudo Shinichi's flashlight, Gao Yuan saw that the space in this lounge was very limited. In addition to a bed, there was only a cabinet about one foot high beside the wall.

Other than that, there are no other furnishings here.

Gao Yuan casually glanced at the furnishings here, then came to the cabinet, opened the cabinet, and seeing that there was nothing inside, he closed the cabinet, walked back to the door, looked at the lock on the door, and found that the door was empty.

There is a keyhole on the outside, and there is no latch or anything like that inside the door.

"How's it going? Did you find anything?"

Xiaolan asked anxiously.

"From this point of view, the possibility of the prisoner being among those four people is very high."

Gao Yuan said, after all, in Kudo Shinichi's account, when Suzuki Sonoko was staying in the lounge, the door was locked and told not to open the door casually, so since the prisoner could take Suzuki Sonoko away in the lounge with the door locked,

There is obviously a key here.

Then, Gao Yuan saw that opposite the lounge was a warehouse, so Gao Yuan tentatively opened the door of the warehouse.

I saw that the furnishings in the warehouse were much more complicated than the rest room. All kinds of sundries were spread there, and there were several cabinets that were the same as those in the rest room, lying sideways on the ground.

Somewhat casually, Gao Yuan opened several cabinets and looked around, but didn't seem to find anything.

So he stood up and said, "It's too late today. Kudo-kun, you should focus on how to confront the prisoner tomorrow. I'll come back here tomorrow to investigate what happened on the ship."

Kudo Shinichi agreed with this, so Kudo and Xiaolan returned to the "Prince Hotel" first.

Gao Yuan, on the other hand, was a little worried outside the "Prince Hotel" - because of the study trip of Didan High School, there were no cheaper vacancies here, and the price of the remaining suites made Gao Yuan reluctant to part with them.

But there seems to be no other hotel nearby!

Forget it, since the tour boat is vacant and there are no police on duty, let's go there and spend the night.
Chapter completed!
