"Brother Youyi! I finally know why you're here alone! Hehe! Just do it! I promise to go back and keep my mouth shut! Hum! ”

Conan, who was also watching Isobei Nagisa leave, looked up at Yuichi, who was still staring at Isobei Nagisa's back in a daze, and stepped on his foot in dissatisfaction, and then mocked in a weird way.

"Hey! Little brother Conan, you've got a lot of skills! It's going to threaten me, there's progress! But what do you know about a little brat? Look at it, this Isobei Nagisa is definitely not simple! She should have an interesting backstory, can you believe it? ”

Lift your feet and move them gently. Not to be outdone, Yuichi pressed his hand on Conan's head, rubbing it desperately as he spoke. And Conan, who was bullied by him, of course, would not just accept his fate and struggled hard.

But while Yuichi and Conan were playing, Tadao Whalei, who came back from the bathroom not far away, sat at his dining table as if he had something on his mind, constantly wiping the sweat from his forehead. After feeling that he still couldn't control himself, he wanted to do something, so he slowly took out a box of cigarettes from the inside of his clothes, took out one, and skillfully put it on his mouth, but the lighter taken out of the pocket of his clothes suddenly failed, and he couldn't hit it.

Just as he was about to throw away the broken lighter in his hand, suddenly Crab Jiang stood behind him with a box of matches.

"Hey! Buddy! I think you need this! Is that right? ”

"Ahh That's right! This damn lighter! Thank you! Friend! ”

"It's okay!"

Everything seems to be happening normally, but Yuichi, who is arguing with Conan, sees something different from the box of matches. If he was not mistaken, it was a half-key, perhaps the same as the key they showed to Teruyoshi Kameda when they first got on the ship. Anyway, Kameda Teruyoshi hasn't come back yet, so it seems necessary to go to his room to find out, if he guesses correctly, he may have some interesting connection with Ye Caisan, who suddenly appeared.

Yuichi, who couldn't find Teruyoshi Kameda in the hall, stopped teasing Conan, and after a glance from Hattori, he politely declined Ran and Isobe Nagisa's request to play poker, and walked towards the cabin. And Conan, who wanted to follow secretly, was picked up by the cautious Yuichi.

"Conan! Sister Xiaolan, they are still missing someone to play poker! You're here to play with Xiaolan and Miss Isobei, this is your task, understand? Help Uncle Maori, and leave this to us, adults! Have fun, you know? ”

"Yes, yes, yes! Conan Kids! Accompany your sister Xiaolan here! Hahaha! ”

The equally unscrupulous Hattori ignored Conan's pleading gaze, laughed, touched Conan's head, and followed Yuichi to turn around and leave the hall.

Conan, who knew what Yuichi was doing here, knew that his mission was very important, but he still gave his middle finger to Yuichi and Hattori's behavior, and the boat of friendship overturned.

After leaving Conan, who was left in the hall to monitor Nagisa Isobe and the others, Yuichi and Hattori, who asked the waiter what room Teruyoshi Kameda was, and Hattori quickly came to the door of Teruyoshi Kameda's room.

"Dangdang!"

"Mr. Kameda! Are you there? Is it better? We are the ship's Hattori staff who Mr. Kanie asked to come and deliver the medicine! Can you open the door? ”

After knocking on the door and pretending to be a waiter, Yuichi and the others found that there was no response.

"Sure enough! What Teruyoshi Kameda said at the restaurant at the time was a lie! It wasn't that he was uncomfortable and went back to his room, or that he did, but halfway through he went somewhere else! If I'm not mistaken, he is one of the three accomplices that Uncle Maori and they are looking for. ”

"What? You said that Teruyoshi Kameda was one of the three robbers who committed the crime with Ye Caisan twenty years ago? What about the evidence? Don't tell me you're guessing! ”

Hattori, who heard Yuichi's reasoning, couldn't help but ask in surprise.

"That's right! Juvenile! You got it right! I just guessed! Before we met you, we met this Kameda at the service desk, and he showed us a strange seal at that time, and Xiaolan happened to see the bottom of the seal, which was engraved with the three characters Furukawa! ”

"Furukawa-Dai? The one who mailed me strange letters? ”

"That's right! But! I just suddenly thought of another possibility, what if this Furukawa Dai is just a pseudonym for one person? And this person's name is Ye Caisan? If that's the case, then combined with the bloody clothes that the police found on the beach, maybe we can assume it! Ye Caisan may have really been overshadowed by these three people at that time and shot him! And the three people who killed the boss couldn't immediately take the money they had snatched to be dashing, so the three people, who were not at ease with each other, hid the stolen money in a bank vault that we didn't know about. And that account opening name is the pseudonym Furukawa Dai, who has long been used by Ye Cai San, and the three of them are holding a seal, one is holding a safe key, and one of them has signed his own handwriting on the bank notes at that time. Seal, key, and signature are the three necessary procedures for a bank insurance vault, and as long as one is missing, the vault cannot be opened. The three of them, who were completely relieved in this way, separated and went incognito, and today, according to Officer Samezaki, it was the time for them to completely break away from legal sanctions, so they came to meet on this ship as agreed! That's why Kameda took that seal and took it out when he saw someone! ”

"But since they're here to sell the stolen goods, why do they want to seduce me, isn't it exciting? Aren't you afraid that I'll catch them all before tomorrow? ”

"Who knows? Maybe the person who called you here wasn't one of the three of them! ”

"Not the three of them? Who would that be? ”

"Who else could it be? Don't forget, it was four people who robbed in the first place! ”

"You mean Ye Caisan?"

"Who knows? Maybe he's on the boat too! ”

Yuichi, who watched left and right and skillfully took out a wire from his trouser pocket and pried open Teruyoshi Kameda's door, shrugged his shoulders at Hattori, pushed the door and walked in.

And Hattori, who was shocked by his unique skill, was stunned for a moment, and immediately stood at the door as if he was a thief, looked left and right, and then got in.

"Hey! You bastard would do this? ”

"Haha! Of course! I think that in order to carry out a mission, my brother was also a person who went undercover in prison! I'll tell you! Brother, I like it so much, it's all talented! If it weren't for the time constraints, I could definitely have learned more in it! You don't care about these things, let's see if there are any important clues in Teruyoshi's room Kameda! ”

Ignoring Hattori's surprise, Yuichi, who had been talking to him, took out the rubber gloves in his pocket and searched them with a magnifying glass after making sure that Kameda Teruyoshi was really not at home.
