Ke Xue: Shinichi and I are childhood friends.

Chapter 1309 "The Perfect Crime"

Yuya shook the three boxes vigorously with his left hand, but no sound came out.

"As you all probably heard, these three boxes are empty."

Everyone nodded.

Yuya casually tossed two of the boxes to Amuro Tooru, who shook them again to make sure there was no sound.

Yuya said calmly, "So, everyone, guess whether this box I'm holding is empty or contains mints?"

Without a second thought, Gu Puyu Hui said, "Of course it's empty. We all heard it. There was no sound when we shook it."

"Is that so?" Yuya's lips curled up slightly as he switched the box to his right hand and shook it.

"Crunch, crunch." The sound of mints colliding echoed clearly in everyone's ears.

Gu Puyu Hui looked completely bewildered: "What's going on?"

Amuro Tooru and the other two focused their attention on Yuya's right sleeve.

Yu smiled and slowly pulled down her sleeve—another box of mints was revealed.

He shook his right hand again, and this time Gu Puyuhui finally heard it clearly; the sound was clearly coming from the box hidden in his sleeve.

Her eyes widened in surprise: "This, this is?!"

Yuya looked at Nishino Sumire, whose face had turned somewhat ashen: "You said you brought a lot of snacks, so it's normal for me to have a box or two of mints in there, right?"

"But, but!" Nishino Sumire still struggled, "We decided to check because we heard the sound of glass breaking..."

Yu said casually, "That's even simpler. Just prepare another phone, set the ringtone to the sound of breaking glass and turn it up to the maximum, and you can control the sound at any time, right?"

“You, what you said is indeed possible…” Nishino Sumi was also unable to refute it, and continued to argue relentlessly, but her tone was somewhat blustering. “However, Kawasaki only ran away in a panic after seeing the message. When he was poisoned, wasn’t I with you guys? How could I have had the opportunity to poison him!”

With his hands in his pockets, Yuya calmly said, "That's because you put honey on his phone, right?"

Sumire Nishino's face suddenly turned deathly pale.

"After receiving the message, Mr. Kawasaki naturally took off his gloves to check it. As a result, his fingers touched the honey on it. Being a severe germaphobe, he couldn't stand the sticky feeling on his fingers, so he hurriedly ran to the bathhouse or toilet to wash his hands and his phone."

“Also,” Yuya paused, “I noticed that Mr. Kawasaki’s handkerchief had a small damp spot and a slight bite mark on it. I guess he might have a habit of putting the handkerchief in his mouth when washing his hands?”

Conan confirmed Yuya's method, saying that he had witnessed the scene when he went to the restroom with Kawasaki Yosuke.

Yuya continued, "You just need to put some poison on the handkerchief, and Mr. Kawasaki will ingest the poison himself. In addition, he has a habit of drinking water frequently, so he will naturally mix the poison with the water and swallow it."

"That way, even if you're not physically present, you can kill Mr. Kawasaki remotely."

After saying all that, Yuu tilted his head and looked at Nishino Sumire, asking, "So, is there anything wrong with my reasoning?"

"Hey, hey, hey!" Nishino Sumiya called out three times in a row, then roared at Yuya, "Whether it's setting a trap, honey, or a handkerchief, I'm not an experienced pickpocket, how could I possibly do that!"

"Really?" Yu raised an eyebrow. "Even if you're not a pickpocket, you must have quite a bit of experience in magic, right? Or are you a seasoned gambler? Otherwise, how could you spot the stains on the playing cards Mr. Amuro brought in such dim lighting?"

"For magicians or expert cheaters, stealing cell phones or handkerchiefs should be an easy thing, right?"

Nishino Sumire stared in shock, staggering backward and crashing heavily into the wall, looking at Yuya with disbelief.

"Furthermore, we found a stack of blank coded forms in Mr. Fujita's bag. Did you put those in while you were getting water?"

"No, I didn't do it!" Nishino Sumi shouted, on the verge of collapse. "These are just your deductions! What evidence do you have to prove that I did it?!"

Yuya smiled faintly: "Of course, I wouldn't be standing here if I wasn't absolutely certain."

Conan, who was listening quietly to the side, twitched his lips slightly, and Amuro Tooru's expression was also somewhat subtle—this guy is putting on an act again.

Wakita Kanenori looked at Yuya with considerable interest. His words were so confident, as if he were pronouncing the crime of a murderer.

Nishino Sumire's heart pounded. Could it be that he really had evidence?

Yu calmly replied, "The reason you made sure there were nine people was to make it easier to divide the lottery paper into nine equal parts so you could achieve your first plan."

"And 9 is also the key to unlocking the code. What is related to 9 is baseball, which is also what you all have in common—you all participated in the baseball club together in high school."

"You used to call someone 'wife.' At first, I thought it was Mr. Nichihara's wife, but it actually refers to the person who plays catcher in the baseball team, right?"

"If you know the key is baseball, then deciphering the code is easy."

"In high school baseball, players' numbers are determined by their positions. If you take the thick square in the middle of the code table as the infield, and then read the nine kana characters in order according to the numbers, you can understand the meaning of the code."

Yuya took out the first cipher paper: "Using this method to decipher the cipher, the cipher everyone received at the beginning was 'The competition is now starting'."

"Then came the second coded message posted at the entrance of the chapel: 'Someone will be eliminated in the toilet.'"

"Then everyone went to look for it together. The code with the eulogy written on it was 'The second person is eliminated in the bathhouse.'"

"Next is the code placed at Mr. Kawasaki's feet, 'Switch people in the study'—does this mean exchanging the murderer's identity and framing Mr. Fujita?"

“Finally,” Yuya said, taking out the coded paper that Fujita Yorito had just received from Nishino Sumiya, “this code means ‘perfect crime’.”

"The blank coded form you put in Mr. Fujita's bag was to make the police think that Mr. Fujita had called his high school classmate, then killed you and the other two, and left a coded message at the scene."

"But the real culprit is you. Even if someone finds out later that the people involved are members of the baseball team and deciphers the code, it will be too late."

"You successfully framed Mr. Fujita long ago, thus completing the so-called 'perfect crime'."

Fujita Yorito's face turned deathly pale. He hadn't expected that his plan would be completely seen through, as if the other party had been watching him commit the crime.

“However,” Yuya stroked his chin, “I don’t understand why you called Miss Gu Pu here as well? It seems that killing her wasn’t part of your plan. Was it just to make up the number of nine people?”

Nishino Sumi also sneered and said coldly, "I'm doing this so that Yu Hui can see just how insidious this man you dated after breaking up with Nichihara in high school really is!"

"What?" Gu Puyu Hui stared wide-eyed in surprise.
