Chapter 1 Kudo Shinichi's Suspicion

"Good morning, Su Bei."

In the second-year corridor of Teitan High School, Suzuki Sonoko's eyes lit up when she saw the handsome boy and she greeted the new transfer classmate.

The boy walking towards me had fair skin and some baby fat on the sides of his face. He casually held his school uniform in his hand, held a piece of bread in his mouth, and squinted his eyes, looking tired.

At this moment, he heard someone calling him. He stopped and thought for a moment, then replied vaguely, "Well, good morning."

"I'm talking to you!" Suzuki Sonoko glared at him in dissatisfaction, "When someone greets you, at least swallow what's in your mouth!"

Su Beixun shrugged, not taking it seriously. He put down his schoolbag and tried to put on his school uniform before entering the classroom. He casually replied, "I can't help it. Who told you to talk to me while I was eating?"

Suzuki Sonoko's mouth twitched, and she looked at him speechlessly with her crescent eyes, complaining: "Really, you deserve it for not making any friends in a month."

"Huh?!" Su Beixun said in surprise. He quickly swallowed the bread. "But I received so many love letters. I thought I was quite popular."

"."Suzuki Sonoko was speechless.

The two of them walked together to the classroom door when a hand slapped Su Beixun's shoulder aggressively.

He turned around and saw Kudo Shinichi's angry face.

"Hey, it's you, right? You were the one who took away the criminal evidence yesterday!"

Mao Lilan, who was with Kudo Shinichi, quickly pulled him back, smiled apologetically at Su Beixun and said, "Don't be like this, Shinichi!"

Suzuki Sonoko, who was standing nearby, smelled some gossip and came over curiously, whispering in Mao Lilan's ear, "What's going on? It's rare to see someone so crazy about reasoning!"

When Mao Lilan saw her best friend, she explained the whole story.

original
After school yesterday, Kudo Shinichi was forced by Xiaolan to go shopping in the mall, and as expected, he encountered a murder case again.

The deceased was a middle-aged man, 54 years old, a freelancer, well. The low EQ term for this is a vagrant.

He died in the cafe on the fourth floor of the mall, in full view of everyone.

Kudo Shinichi judged that he died of cyanide poisoning based on the almond taste in his mouth.

There are three suspects in total: the store manager who made the coffee, the waiter who served the coffee, and a friend who was sitting opposite the deceased when he died.

This case is not complicated, the modus operandi is not strange, and by screening out the motive, it is easy to focus on the deceased's friend.

The deceased had borrowed a large sum of money from his friend and had been dragging his feet on repaying the loan. This time he came to the cafe because his friend had asked him to come here to discuss and negotiate.

The other two people had no close social relationship with the deceased.

Especially after the police arrived and found that there were cameras installed in the store, solving the case became much easier.

Through surveillance, it can be clearly seen that while the deceased was going to the bathroom, his friend dripped a little strange liquid into the deceased's coffee cup.

"What's wrong with this case? It seems very clear when you put it that way!" Sonoko asked curiously.

According to what Xiaolan said, the murderer must be the deceased's friend. What does this have to do with Su Bei?
Kudo Shinichi rushed to speak: "But the other party denied that he poisoned the deceased's coffee. According to him, he only added white vinegar. He said that he was a friend of the deceased and knew that the deceased had the habit of adding white vinegar to his coffee, so..."

"Huh?" Suzuki Sonoko curled her lips speechlessly, "This excuse is too perfunctory, how could anyone believe it?"

"But." Kudo Shinichi's expression became serious, "In addition to cyanide, white vinegar was indeed found in the coffee cup of the deceased."

"And the bottle found on the suspect was indeed filled with white vinegar."

"Really? Ha, ha ha."

Suzuki Sonoko had an expression that said, "There are many strange things in the world." "But this also means that the friend of the deceased is not the murderer. The murderer must be one of the other two suspects!" "You are such an idiot!" Kudo Shinichi rolled his eyes and complained, "How can you draw such a simple conclusion?"

"According to my speculation, the deceased's friend must have had two bottles with him, one of which contained a mixture of white vinegar and cyanide, and the other bottle contained only white vinegar."

"The surveillance camera captured that after the poisoning, the deceased's friend also went to the bathroom. He must have disposed of the bottle of poison during this time!"

Suzuki Sonoko scratched her head, not happy with being called an idiot, and said irritably: "So, what's so strange about this case?!"

"Because the bottle is missing." Mao Lilan hurried over to comfort her bestie, "The police searched the bathroom from all angles, but no poison was found in the toilet, trash can, sink, or sewer, and no small bottle or its fragments were found."

"Oh——?" Suzuki Sonoko stretched out her tone and gloated, "Doesn't this mean that this reasoning geek didn't guess right at all?"

Kudo Shinichi turned into a big head and roared: "I didn't guess! I relied on reasoning!"

Then he stared at Su Beixun's face again: "Besides, if we can't find the bottle, there is another possibility! Someone took it away! After the deceased's friend, the only person who went to the bathroom was you!"

Being stared at by Kudo Shinichi, Su Beixun still looked calm. He looked at Kudo Shinichi frankly, slapped away the hand that was patting his shoulder, and smiled at Kudo Shinichi: "It sounds like that, but do you have any evidence?"

"What's the difference between reasoning without evidence and blind guessing?"

Kudo Shinichi looked unhappy.

"After I came out of the bathroom, I was in a place where the surveillance camera could capture me. The police also listened to you and searched me, but they didn't find anything, did they?"

"Besides, why would I help the deceased's friend? He and I don't know each other and have no connection. Why would I risk my life for him?"

Kudo Shinichi gritted his teeth and said nothing.

Su Beixun was right. Whether from the motive or the body search, Su Beixun had nothing to do with this case and should not have anything to do with it.

However, when the police went to search the toilet without any results, the deceased's friend subconsciously glanced at Su Beixun. The detective's intuition told Kudo Shinichi that Su Beixun must be involved in this case!
But I can't find any evidence.

What trick did he use?
The bottle disappeared, could it be made of ice? Kudo Shinichi thought, the camera was not high-definition, and because the hand blocked most of it, the material of the bottle was not clear.

But even if the bottle is made of ice, what about the poison? Why can't even the poison be detected?

"I'm curious, why are you staring at me?" Su Beixun leaned closer, opened his squinting eyes, revealing dangerous and strange scarlet pupils, and stared at Kudo Shinichi who was in deep thought, "I don't remember offending you?"

"It would be fine if there was only one possibility, but now, the suspicion of the store manager and the waiter killing randomly has not been completely ruled out. Instead of caring about them, you are making things difficult for me, an innocent person who happened to be in the cafe."

"Oh! I see." He exaggeratedly made a surprised expression and leaned back against the wall. "It's arrogance."

"That's right, how can the police's savior be wrong? The murderer must be a friend of the deceased, so in order for his modus operandi to be valid, I must also be an accomplice, right?"

Kudo Shinichi was so angry that his face turned red. Before he could say anything, Su Beixun pushed him away and walked into the classroom.

"I don't want to waste any more time with you. If you still think I'm an accomplice, you can call the police to arrest me. Of course, the prerequisite is that you can produce evidence."

Kudo Shinichi staggered and shouted at his back: "No matter what tricks you use, there is only one truth! I will definitely find evidence to make you confess!"

Su Beixun did not respond.

Watching Su Beixun disappear, Kudo Shinichi complained again: "Really, he actually said that I was arrogant, I think he is the truly arrogant one!"

"Okay, Shinichi." Mao Lilan comforted him: "You suspect him without any evidence, so it's natural that he will be angry."

"Yes, yes." It was rare to see Kudo Shinichi being humiliated, so Suzuki Sonoko was a little happy. "Besides, Su Bei is so pretty, how could he be an accomplice? You must have made a wrong deduction!"
