Takato felt a little strange from the beginning, obviously yesterday Kudo Shinichi swore that he was not interested in the school trip, but he came to participate in the school trip today.

And listening to Mao Lilan's simple description of the incident, Takato felt that Kudo Shinichi's behavior on the ship today was also a little strange.

Therefore, Takato had a guess, so he deliberately tested Kudo Shinichi just now. When Kudo Shinichi affirmed that Suzuki Sonoko was fine, Takato knew that his guess was right - Kudo Shinichi expected Suzuki Sonoko to be kidnapped on the ship today!

"What do you mean?"

Mao Lilan didn't quite understand the meaning of Takato's words, but looking at Kudo Shinichi's performance at this time, he also knew that he seemed to know something, so he shouted as if asking.

"Shinichi!"

Hearing Xiaolan's question, Kudo slowly chased after him, looking a little self-reproachful, looking at Xiaolan embarrassedly, and then looking at Gao Yuan on the side.

"I'll be honest with you. Someone sent me a challenge letter from someone claiming to be a kidnapper. He said he would kidnap a classmate on a school trip. Then, just now, this guy called and issued a second criminal statement, tomorrow at noon, he will kidnap another person. While making that call, I heard the voice of the garden, confirming that she was okay. ”

Speaking of this, Xiaolan was a little sad, and tears began to roll in her eyes.

"Little Orchid......"

Looking at Xiaolan with such an expression, Kudo was a little unbearable.

"Why ......"

With a crying voice, Xiaolan stared at Kudo, a little hysterical, "Why didn't you call the police when you received the challenge!" Cases are not games! ”

As she spoke, Xiaolan grabbed Kudo's cuffs and asked, "Putting the people around you in danger is not what a detective should do!" ”

Hearing this, Kudo looked away.

"I didn't think it was a game."

As he spoke, his eyes were firm: "This is, my contest with that guy!" ”

"Fight?"

Hearing this, Xiaolan couldn't understand it, and shook her head tremblingly, "What's the point of competing with such a despicable person!" ”

"Meaningful!"

Kudo said, "It is precisely because the prisoner is a despicable person that if I evade this challenge this time, the next time the prisoner may do something more despicable to provoke." The challenge book says that if he doesn't comply with the requirements of a one-on-one duel, he'll mess around. ”

Hearing this, Xiaolan seemed to understand Kudo's intentions.

"And ......"

Looking at Xiaolan like this, Kudo's words were never spoken.

"And ...... What ......"

Xiaolan asked softly.

"No, nothing."

Looking at Xiaolan's expression, Kudo's eyes began to dodge a little.

"Uh-huh."

At this moment, Gao Yuan coughed lightly, breaking the star-to-eye between the two-they, did they forget that I was still here?

Hearing Gao Yuan's voice, Xiaolan and Kudo seemed to remember that there were still people here.

"I'm sorry, Mr. Wise. Because of the prisoner's request, this is a one-on-one duel between me and him, so I ......"

"So what? You just said the prisoner called you? What number does the other party use? And what exactly do you say? What did the garden say when you heard the sound of the garden? ”

Takato asked a few questions in a row, interrupting Kudo Shinichi's words.

To this, Kudo Shinichi thought for a moment and began to answer.

"The other party is using an encrypted number. When I inquired about the garden, I heard a knock on the door, and then I heard the garden shouting, "Get me out, you bastard." ”

"A knock on the door?"

Gao Yuan asked.

Hearing this, Kudo Shin recalled at first - "It was like the sound of a knock on an iron door...... Like, there are echoes...... Damn, can't think of more! ”

Speaking of which, Kudo Shinichi seemed to realize the purpose of Takato asking this question, but at that time, his attention was all on the kidnapper, and he actually ignored the more important information on the phone!

"And what did the kidnapper say? Do you remember what he said? ”

Takato knew that Kudo Shinichi would not be able to recall this information for a while, so he asked the next question.

He said: This is really a game without difficulty, and it is so boring to give you such obvious hints and still do this. So, I'm going to kidnap one more person tomorrow. Don't be too nervous, this time to give you a more obvious hint, tomorrow's kidnapping is at twelve o'clock at noon, every minute and every second. ”

Kudo Shinichi repeated the kidnapper's words, and then said seriously:

"Anyway, no matter what, stop that guy from committing the crime again. And, be sure to get that guy out! Xiaolan, Mr. Wise, please trust me! ”

"I believe in you."

Xiaolan couldn't help but say when she saw Kudo Shinichi who was so serious.

"But on the other hand, please don't hide it from everyone anymore!"

Looking at Xiaolan's pleading words, Kudo Shinichi nodded silently, and then looked at Takato.

"Is there anything else you'd like to ask, Mr. Wise?"

"Since you know that someone is going to be kidnapped today, you must have been watching carefully the whole time while you were on the boat. Can you tell us about it? From your point of view, the complete story of this Suzuki-classmate kidnapping incident? ”

Gao Yuan asked.

In this regard, Kudo Shinichi cannot deny.

"Today, when this sightseeing boat was sailing on Lake Ashi, there were only four outsiders on board who were not very familiar with us, except for our classmates: Mr. Shingo Kitajima, who had recently come to our class as a substitute teacher and the lead teacher of the school trip, Ms. Mai Nishida, the tour guide, Mr. Kyosuke Minamida, the crew member, and Mr. Kunio Higashi, the captain of the ship."

After Kudo Shinichi briefly explained the candidates he suspected, he began to talk about the whole thing today:

During the day, Lake Ashi, on a tour boat-

After the captain of the ship, Kunio Higashi, gave a brief introduction to the ship's emergency response plan, Kudo Shinichi and other students who came to participate in the school trip began to move freely on the ship.

And Suzuki Sonoko seemed to have a good impression of the appearance of the crew member Kyosuke Minamida, so she began to show favor to him frequently, but Kyosuke Minamida refused on the grounds that she had a job.

The route of the voyage, introduced by the tour guide Mai Nishida, is that the boat will circle the lake in one circle, which takes about an hour.

In other words, the next hour will be a secret room on the water! Let the horses come, and I'll protect them!" ”

After understanding this basic information, Shinichi Kudo, who was standing on the deck at the top, thought so.

But at this time, the crew member Kyosuke Minamida suddenly came to Kudo Shinichi's side and asked tentatively: "Yes, high school detective, Kudo Shinichi?" ”

"yes."

Shinichi Kudo responded.

"I'm a fan of yours! It's an honor to meet you! ”

Hearing this answer, Kyosuke Minamida was a little excited, wiped his right hand on his clothes, and stretched out his hand to shake hands with Kudo Shinichi.

Kudo Shinichi glanced at the crew member who suddenly came to talk to him with some scrutiny, but seeing that he didn't seem to be smiling fakely, he still reached out and shook his hand.

But because there was still work for the crew, Kyosuke Minamida walked to the cabin after shaking hands. At this time, Suzuki Sonoko immediately followed enthusiastically and began to ask if he had a girlfriend, but Kyosuke Minamida avoided Suzuki Sonoko on the grounds of work, but Kudo Shinichi saw that Suzuki Sonoko still followed Kyosuke Minamida and entered the cabin.

After that, Kudo Shin began to inspect various parts of the ship, and found that it was impossible to sneak in from the outside while the boat was sailing on the lake—in other words, the kidnappers should have been on board a long time ago!

With this in mind, Kudo Shin began to observe the four outsiders he was not familiar with.

The captain of the ship, Kunio Higashi, has been controlling the helm in the control room, and the substitute teacher Shingo Kitajima and the tour guide Mai Nishida have been discussing more details of this school trip on the deck of the bow of the ship, and only the crew member Kyosuke Minamida has been chasing and running by Sonoko Suzuki.

Everything, all normal, under Kudo Shinichi's observation, did not find anything strange on the ship and people who behaved strangely.

And the accident happened at this time-

"Yikes!"

Suzuki's voice came from the aisle on the right side of the boat at this time, and Kudo Shinichi immediately rushed over when he heard the sound, but what he saw was Suzuki Sonoko, who felt uncomfortable because of seasickness and leaned on the boat fence and wanted to vomit.

"So it's just seasickness?"

Walking to Suzuki Sonoko's side, Kudo Shinichi breathed a sigh of relief, but Suzuki Sonoko's shout just now attracted the attention of the other members of the ship, and Shingo Kitajima, Mai Nishida, and Kyosuke Minamida all ran over when they heard the sound.

"Suzuki-san, are you alright?"

Shingo Kitajima looked particularly nervous, and asked about Suzuki's situation, and his hand involuntarily seemed to be comforting a child, and quickly comforted Suzuki Sonoko's back a few times.

"Teacher, please don't touch me, I'll want to vomit more."

Shaking off Shingo Kitajima's hand, Sonoko Suzuki said with a little discomfort.

"Then, let's go to the lounge and lie down for a while, it will be better."

Kyosuke Minamida stepped forward at this time and proposed, "Kudo-san, can you help?" ”

Kudo Shin nodded in response, so Kyosuke Minamida and Kudo Shinichi helped Suzuki Sonoko to the lounge in the cabin, and Mao Liran, Mai Nishida and Shingo Kitajima also followed to the lounge.

"Thank you, Mr. Nantian."

Lying down on the bed in the lounge, Sonoko Suzuki said with a slight nymphomaniac.

"Ahh Seasickness medicine! ”

Mao Lilan, who was on the side, looked at the situation of Suzuki's garden, began to rummage through his pockets, and then said helplessly, "If only I had brought it!" ”

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

Mai Nishida took out the seasickness medicine from the backpack she was carrying at this time and said, came to the bedside, and handed the medicine to Suzuki Sonoko.

"Thank you, Mai-sama."

After taking the medicine, Suzuki Sonoko said reassuringly.

"No thanks, it's my job."

Mai Nishida said, and at the same time, Kyosuke Minamida handed mineral water to Sonoko Suzuki.

"Really, the eldest lady who sits on the speedboat at home all day long, what kind of boat is seasick."

Shinichi Kudo said on the side.

"The speedboat at home!"

Hearing this, Kyosuke Minamida and Mai Nishida said in great surprise.

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

Teacher Shingo Kitajima explained.

"What do you mean by looking like this?"

For the teacher's words, Suzuki Sonoko, who had just finished taking the medicine, was a little displeased, and then looked at Kyosuke Nanda, "Mr. Nanda, you will always be with me, right?" ”

"Well, I still have a job!"

Kyosuke Minamida said embarrassedly.

"We're with you in the garden!"

Mao Lilan said at this time with Kudo Shinichi.

So, Kyosuke Minamida, Mai Nishida and Shingo Kitajima left the lounge with peace of mind and went to do their own things.

"Ah...... Mr. Nanda is gone. ”

Slightly lost, Suzuki Sonoko said.

"Garden!"

Xiaolan sat on the edge of the bed in the garden and persuaded a little angrily.

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

Suzuki Sonoko saw Xiaolan's disgust at her behavior, and couldn't help but feel relieved, "My words will be fine alone." ”

As he spoke, 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 stay obediently!" ”

"Alright, let's go!"

Urging, Suzuki Sonoko said.

So Xiaolan pulled Kudo out of the lounge, but before leaving, Kudo instructed Suzuki Sonoko: "Garden, lock the door back, don't open the door if anyone comes except me!" ”

Sonoko Suzuki was a little puzzled by this, but did so.

That's what happened on board.

What happened after that, is what Takato already knew - when the boat was near Hakone Shrine, when the tour guide Mai Nishida introduced the origin of Hakone Shrine to the students, there was a sound of falling water at the stern of the boat, and Shinichi Kudo took the lead in running to the stern to check, and Moriran followed closely behind, and as a result, on the lake behind the stern, he saw Suzuki Sonoko's headband.

So, everyone ran to the lounge where Suzuki Sonoko was, and found that the door of the lounge, which should have been locked, was opened, and then, looking everywhere on the boat, they couldn't find where Suzuki Sonoko was.

After that, the tour boat docked and called the police. Police found the suspect in the woods near the suspect with a wetsuit and oxygen tank. ”

After Kudo Shinichi finished talking about what happened, he explained the follow-up discovery, "But just now, I started looking near the torii gate of Hakone Shrine until I found the place where the wetsuit and oxygen tank were found, and judging from the map, this distance is too far. ”

"There is no mistake, the prisoner did not leave by diving."

Gao Yuan said, pointing to the railing at the stern of the ship at this time and said, "There are traces of burning. If you're not mistaken, the sound of falling water you heard at the time should have been designed by the prisoner. For example, a heavy object is tied here with a rope in advance, and then a small ignition device is installed, and when necessary, the prisoner control mechanism burns the rope, and the heavy object will fall into the water, creating the illusion that someone has jumped into the water at that time. ”

Hearing this, Kudo Shinichi leaned over and touched the outside of the railing with his hand, only to find a trace of black matter left behind after burning.

"Sure enough."

Shinichi Kudo agreed.

"Obviously, then, the prisoner should have activated the mechanism while all of you were listening to the guide's explanation and staying on the front deck of the ship. In other words, the prisoner is indeed the person on the ship, and the disappearance of Suzuki-san, must have been before that. ”

"Under the circumstances, it was impossible for the prisoners to take people away from the ship, so they should just hide the people on the ship......"

Hey, wait a minute, if you say this, isn't this technique a bit similar to the way Nakagawa Moemi kidnapped Suzuki Sonoko in Teidan High School before: At that time, Nakagawa Moemi made people think that Suzuki Sonoko was taken out of the old school building, but in fact, she only temporarily hid people in the old school building. It's just that he saw through Nakagawa Moemi's methods in advance, and didn't let Suzuki Sonoko really be kidnapped.

"However, we have checked all the places on the ship, and we have found no garden anywhere!"

Xiaolan said anxiously, "That's right, Shinichi! ”

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

Kudo Shinichi said.

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

Gao Yuan said.

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

Walking into the lounge, by the light of Kudo's flashlight, Gao Yuan saw that the space in this lounge was very limited, except for a bed, only a cabinet about one height was placed on the wall, and there were no other furnishings here.

Gao Yuan glanced at the furnishings at random, then came to the cabinet, opened the cabinet, and looked at the empty inside, then closed the cabinet, walked back to the door, observed the lock on the door, and found that there was a keyhole outside the door, and there was no latch or anything like that in the door.

"How? Did you find anything? ”

Xiaolan asked anxiously.

"In this way, there is a high probability that the prisoner is among those four."

Takato said, after all, in Kudo Shinichi's account, when Suzuki Sonoko stayed in the lounge, he locked the door and told him not to open the door casually, so since the prisoner was able to take Suzuki Sonoko in the locked lounge, it was obvious that he had the key here.

Then, Gao Yuan saw that opposite the lounge, there was a warehouse, so Gao Yuan tried to open the door of the warehouse.

I saw that the furnishings in the warehouse were much more complicated than in the lounge, all kinds of miscellaneous items were spread there, and there were several, the same cabinets as in the lounge, which were placed horizontally on the ground.

Somewhat casually, Gao Yuan opened a few cabinets and looked at them, but he didn't seem to find anything.

So he got up and said, "It's too late today. Kudo-san, you better focus on how to fight the prisoner tomorrow. I'll come here tomorrow to investigate the things on the ship. ”

In this regard, Kudo Shinichi agreed, so Kudo and Xiaolan went back to the "Prince Hotel" first.

Gao Yuan, on the other hand, was outside the "Prince Hotel", and was a little worried - because of the study trip to Didan High School, there were no cheaper vacant rooms here, and the price of the remaining suites was really reluctant for Gao Yuan.

But there doesn't seem to be any other hotel around here!

Forget it, since the tour boat is empty and there is no police on duty, let's go there for a night.

However, that night, Gao Yuan, who was lying in the lounge, could no longer sleep because he faintly heard the sound of people walking on the boat......
