I was in Conan, and after picking up Xiao Ai, I was chased by Hongzi.

"So, Shiratori-kun. What do you think the prisoner's motive is?"

"I think it can be concluded that it was a personal grudge. The murderer did not touch the deceased's wallet or gems."

Takagi Wataru opened the previous record, "There was no sign that the door lock of the room had been broken open. I guess that either the victim opened the door himself and let the murderer in, or the murderer had a master key and sneaked in secretly."

Upon hearing this, Officer Megure immediately looked at the staff, "Does anyone have the master key?"

The staff member who was responsible for calling the police said with a queasy look on his face: "There are quite a lot of people there. In addition to me, there are also guards and Tsujimoto who is responsible for daily life. In addition, there are director-level waiters, almost everyone has them."

"I see."

"Officer, the murderer strangely chose to attack when the deceased was alone, which means the murderer should know the deceased's itinerary very well." Shiratori Rensaburo said.

"Hmm -" Officer Megure turned his head, "Ms. Tsujimoto, are you responsible for arranging the trip for the two of them?"

"Yes."

"Then who else knows the schedule of the two of them?" Officer Megure asked.

"About their itinerary," Tsujimoto Kaho looked at the staff on the side, "I only mentioned it to the Misaki Master. Others don't know."

"Um--"

"In other words." Shiratori Rensaburo said softly: "If you were ten centimeters taller or Mr. Misaki were ten kilograms thinner, you would be the most suspicious suspect."

Tsujimoto Kaho and Director Misaki looked at each other, but did not say a word of defense.

"One more thing." Mouri Kogoro looked at Officer Megure, "Is the attack on Miss Sonoko related to these two cases?"

"Yeah - but, since you passed the suspect and didn't see his face..." Officer Megure rolled his eyes.

"Oh~ It's really embarrassing..." Mouri Kogoro touched his head in embarrassment.

"But, Officer Megure." Mouri Kogoro said with a confident smile, "This is a secret room at sea. I think the prisoner must still be on this ship."

Shiratori Rensaburo shrugged and said noncommittally: "The total number of crew members and passengers is only more than 600, right?"

Mouri Kogoro's face suddenly showed an expression that was more uncomfortable than eating shit.

"Anyway, Mr. Takagi." Officer Megure straightened his hat and began to make final arrangements. "You continue to inquire with the passengers and find witnesses."

"Yes."

"Mr. Misaki and Ms. Tsujimoto, please elaborate on the crew and passengers."

"Ok."

"no problem."

Hearing this, Conan sat down with his arms folded, "It is indeed as Officer Shiratori said, when did the prisoner learn about the Yashiro father and daughter's itinerary? Ms. Tsujimoto said that she never mentioned it to anyone..."

"Da da."

Otoi Hiroshi tapped his glasses, "Idiot, what method would you choose if it were you?"

Conan was startled, "The bug...that's what it is."

"Hey, sister, I have something to ask you!" Conan suddenly got out from under the table.

Otoi Hiroshi slapped his forehead, "Your identity as a child is indeed very useful, but it makes me look very ignorant, bastard!"

"Conan?" Officer Megure blinked.

"Damn it, you little devil." Mouri Kogoro turned sideways with one hand on the table, "You came out of nowhere!"

The moment he flew towards Conan, Conan nimbly dodged.

Mouri Kogoro suddenly jumped into the air and hit the chair. After sliding down, he raised his head and looked into a pair of clear eyes.

"what--"

"You, your kid is here!" Mouri Kogoro was startled.

Otoi Hiroshi reluctantly got out from under the table, patted his butt and pointed at Conan and said, "He is really curious, so I brought him here because I had no other choice."

"He is a brat, are you too?!" Mouri Kogoro shouted.

Hiroshi Otoi slowly took out his ID card and said, "That's right, I'm still underage."

"But, damn it——"

On the other side, Conan obediently ran to Tsujimoto Kaho and asked, "Did you mention today's itinerary in the president's room last night?"

"Yes." She nodded, "I confirmed the itinerary with them when I sent them back to their room after dinner."

"Then was there anyone in the president's room last night?" Conan then asked.

"Let me think about it..." Tsujimoto Kaho blinked his smart eyes, "Yesterday, President Yashiro said that he felt very tired and wanted to rest before dinner, so no one was in the room during dinner."

"I see."

"You brat. Yes! No! Yes! Steal! Listen! We! We! Talk!! Ah!"

At this time, Mouri Kogoro, who was frustrated at Otoi Hiroshi's side, found Conan's side.

"Eh?"

Conan felt a chill rising from his back, trembled unconsciously, and slowly raised his head.

——Mouri Kogoro gritted his teeth, his mustache kept trembling, and his ferocious appearance was like an evil spirit from the abyss.

"hateful!"

Mouri Kogoro's fist hit Conan's head hard, but Conan nimbly dodged it and hit the table accurately.

"Ah - it hurts, it hurts -"

Taking advantage of Mouri Kogoro's distraction, Conan ran to Director Misaki again, "Mr. Misaki, are there any passengers who didn't go to dinner?"

"Everyone should be present."

……

Conan held his chin and murmured: "So the murderer is a crew member?"

Otoi Hiroshi came over and leaned into his ear, "You forgot that there was someone who left early last night. The one who inexplicably pestered Uncle Mouri and said he was his fan."

"I see."

Conan ran behind Tsujimoto Kaho again, "Sister, has Mr. Kusaka interviewed you?"

Tsujimoto Kaho turned around playfully, "Are you talking about Mr. Kusaka Hiroyuki? Yes."

"after that……"

——Conan was captured by Moori Kogoro.

Otoi Hiroshi continued what he said and asked: "Have you ever briefly lost your master key?"

Tsujimoto Kaho looked at the handsome young man close at hand, her cheeks flushed slightly, and she whispered: "We did lose a master key three weeks ago."

"Is it really true?!"

Kogoro Mori, who was teaching Conan a lesson, was stunned.
