“Ahem, um, brothers, and brother Shimizu, the forensic results are out, and there is no poison left in Mr. Urata’s drink cup.”

“Nani?!”

Not to mention the shock of several detectives, on the other side, Yumemi Noda, Yōta Mitani and Mai Kougami who had just returned, couldn’t help but want to complain when they saw Inspector Megure making this speech with a look of relief on his face.

Mr. Officer, your expression is not right! ?

Chapter 543 Seeking the enemy in the void

The detectives knew very well what the lack of any poison residue in the beverage cup meant. Not only did Shimizu Koji lose his status as a suspect, but the case was also completely out of control.

There is no poison in the drink, so where is the poison? !

“Inspector Megure?! Then, where was the poison found?!”

Kudo Shinichi couldn’t help but ask first, and Mori Kogoro and Hattori Heiji followed closely behind, and the pressure instantly fell on Inspector Megure.

Inspector Megure didn’t expect that one problem would be solved before another one arose. Why are these guys so annoying?

Being watched by many people, Officer Megure’s expression gradually became a little embarrassed. “Well, according to the feedback from the forensic personnel, it seems that no traces of poison have been found so far.”

The expressions of Kudo Shinichi and Hattori Heiji were as if they were struck by lightning, and Shimizu Koji was almost taken away just now, and Kazuha was misunderstood, but neither of them showed such expressions.

Koji Shimizu frowned slightly, and glanced at the somewhat nervous Mai Hongjo inconspicuously, but suddenly a sentence that he didn’t pay much attention to just now flashed through his mind.

“I put the poison in the ice.”

Before, he only cared about the reason why Hong Shang Mai killed people. As for the method of poisoning she explained, Shimizu Koji didn’t pay much attention to it. Now that he thought about it, he suddenly discovered

interesting.

It seems that he was too anxious and hid the liquid poison in the ice. Although Koji Shimizu thought this was a bit far-fetched, it was not impossible to succeed, and it was already a successful case.

Thinking of this, Shimizu Koji’s eyes flashed, and he took the initiative to step forward, “In this case, I should be clear of suspicion. However, if the murderer did not use the drink, how did he poison it?”

“Officer Megure, the poison is potassium cyanide, right?”

“Ah, yes, what’s wrong, brother Shimizu?!” Inspector Megure looked faintly expectant.

But Koji Shimizu did not do as he thought. He did not start to solve the problem like his younger brothers Kudo or Mori.

“If I remember correctly, cyanide poisons are fast-acting and are one of the fastest-acting poisons that can kill people. This can rule out the possibility that Mr. Urata was poisoned outside of school.”

Everyone held their breath and looked at Shimizu Koji quietly, and Mai Hongjo in the crowd couldn’t help but become nervous. She couldn’t understand why Shimizu Koji was doing this.

She couldn’t help but wonder if this strange boy, Shimizu Koji, had changed his mind and was planning to expose her identity.

Seeing that most people were aroused, Shimizu Koji smiled and turned around and said, “Conan, how long does it take for cyanide poisons to take effect?”

After hiding in the crowd for a long time, Haibara Ai, who was happy to be free, raised her eyebrows when she heard the words and walked out silently. At this time, many people noticed that Conan, who usually ran around, was so well-behaved today.

This was also Shimizu Koji’s little idea. In order to solve the problem once and for all and avoid being suspected by Xiaolan later, he called out Haibara at the last minute.

Just now, when Koji Shimizu went to talk to Mai Hongo, although he didn’t bring her directly with him, she followed him, but Mai Hongo didn’t notice it.

When Haibara Ai knew about Shimizu Koji’s plan, she did not raise any objections in the end, which made Shimizu Koji happy. At least his Shiho was not a stupid person who blindly believed in law and justice.

However, considering Haibara Ai’s growth experience in the organization and what he has learned over the past six months, it is completely predictable that she would make such a choice.

“Potassium cyanide is a highly toxic drug. If an average person takes 50 mg, they will die. This process usually only takes a few minutes, so even if it is discovered, it is too late to provide emergency treatment.”

“But this type of drug is difficult for ordinary people to make, and even if they buy it, it is difficult to buy it directly.”

Haibara Ai probably guessed what Shimizu Koji was going to say, because Shimizu Koji had told her before that after he went to the Metropolitan Police Department, he would put the blame on the crime to an unknown killer.

Anyway, without evidence, it’s not up to them to decide.

Although it was the first time that Haibara Ai helped to cover up the truth, she had no objection because not only herself but also her sister. If they really accepted the so-called legal sanctions, they would probably have to die many times. Even if Japan did not have the death penalty, they would still be sentenced to hundreds of years in prison.

A group of adults, as well as students who were still watching nearby, all cast curious glances at Conan, who was transformed by Haibara Ai. Haibara Ai was not at all stage-frightened, and directly ignored Kudo Shinichi’s constant winking at her. She just paused for a moment, and continued in a cold voice:

“So, generally speaking, this drug is used to kill people. In addition to fully prepared murders, there is also a special situation where people hire someone to kill someone.”

Hiring a killer?!

This word is both familiar and unfamiliar to these detectives. What is familiar is that such things are not uncommon, but what is unfamiliar is that they have hardly ever encountered such a situation. They usually only deal with the police, victims, and murderers. As for the killer, it cannot be said that they have never heard of it, but they have never seen it either.

“Hey, hey, hey! Conan! Where are you from——”

“It was me, Officer Megure. I told him. This kid just asked me these questions out of curiosity. Haha.”

Before Inspector Megure could finish being surprised, Kudo Shinichi came to his senses and quickly stood up. However, as he spoke, he subconsciously walked over and wanted to touch Conan’s head. This seemed normal to outsiders, but Haibara Ai swung her hand and directly knocked Kudo Shinichi’s hand aside.

Fortunately, no one paid attention to such details, and Kudo Shinichi was embarrassed for a second but then recovered.

His explanation successfully made everyone present start to think: Is it really possible to hire someone to kill someone?

Hattori Heiji and Maori Kogoro were still a little reluctant to accept the detective’s intuition. Maori Kogoro was also a little serious today. After all, it was his daughter’s drama performance that was ruined. Uh, although –

Well, good destruction!

“So, this incident is most likely a murder for hire?” Inspector Megure said to himself.

And Shimizu Koji immediately followed up and said, “This is just a guess, but Officer Megure, you can ask the forensic personnel to check the body again to see if there are any scars like pinholes. If there are, then it is very likely.”

After Shimizu Koji said this, no matter what the detectives thought, the matter seemed to be settled. Even Kudo Shinichi began to believe it if such a wound was really found.

Of course, such a wound existed. When Koji Shimizu walked back to the scene and passed by the corpse, he had already made arrangements.

Chapter 544 Mysterious Invitation

Killers and the like are people from almost two different worlds from these detectives. Even though Kogoro Mouri has experience as a policeman for a while, he has almost never dealt with killers.

There is no doubt that cases like these will be left entirely to the police. Even if they want to help, they don’t have the time and energy.

“Thank you. Thank you so much.”

“No need to thank me. Your method is sophisticated enough. If it were just the police, they would hardly suspect you.”

Shimizu Koji smiled faintly, and Hong Shang Mai’s somewhat uneasy mood was slightly calmed down by his strange way of comfort.

And until a few minutes ago, she was still trembling in her heart. She killed someone.

“If there’s nothing else, let’s just say goodbye.”

“Hey! But, this, this——”

“No need to thank me. I don’t think you would want this to become a burden on your heart. Just pretend that today never happened.”

Koji Shimizu waved his hand and turned away.

If Hong Shang Mai’s eyes hadn’t been full of gratitude and anxiety, begging him to come over for a private chat, he wouldn’t have come over. After all, this kind of thing was really just a piece of cake for him.

The matter ended hastily and the murder case was ultimately left unresolved, but time had already been wasted and the first day of the school festival ended with a sudden downpour.

In the next few days, Koji Shimizu first sent Kazuha and Hattori on the train back to Osaka with everyone, and then accompanied Tetsumoha and Tsukamoto Kazumi at the school festival for two days respectively, and time passed quickly.

At Dr. Agasa’s house, although Kazuha and Hattori have already gone back, Shimizu Koji is still living here for the time being.

There was a light “click” sound, and then the familiar cold voice of Huiyuan Ai was heard from the entrance, “I’m back.”

“Huh? School is over so early? Isn’t it only noon now?”

“There may be heavy rain in the afternoon. For the safety of students, the afternoon classes have been cancelled.” Haibara Ai changed into slippers and said as she walked into the living room.

Koji Shimizu sat on the sofa and turned his head to look. Sure enough, it had become dark outside the window. It was only one o’clock in the afternoon, but the sky now seemed to be approaching evening.

“Then you should let me pick you up.”

“I wouldn’t forget to bring an umbrella, and it wasn’t raining.”

“Crack!”

As soon as Haibara Ai finished speaking, there was a flash of lightning, accompanied by the roar of thunder. The sky outside suddenly brightened and then darkened, and raindrops as big as beans began to fall.

Haibara Ai was silent for a moment, then slowly walked to the sofa and sat next to Shimizu Koji.

She could sit like this all day long, quietly without being disturbed.

Dr. Agasa is not here, probably because he is preparing for their camping trip tomorrow. However, since they are driving, they don’t need to worry about anything.

“Is there anything wrong with the organization?”

“Well, not yet. Gin and I don’t have a good relationship, so even if there is, he won’t look for me.”

As Shimizu Koji said this, he put his arms around her shoulders and with just a little force, Haibara Ai’s small body fell into his arms.

But he just hugged her. They have now passed the passionate days in the beginning. Compared with physical things, the spiritual feelings are more nostalgic.

When Haibara Ai sat on the sofa, she naturally took off her slippers. She was not tall enough and her feet couldn’t even touch the ground. Shimizu Koji liked to see her sitting on the sofa like this because there was an indescribable feeling in it.

The pure white socks, just reaching the calf, are spotless and very fresh. Koji Shimizu casually holds them in his hand. Even through a layer of cotton socks, Haibara Ai’s small feet are still soft and delicate.

“I just took off my shoes.”

Haibara Ai’s expression remained calm and her voice was as quiet as still water. When Shimizu Koji heard her words, he stopped short of picking it up and sniffing it.

“Hey, it’s okay, I’ll just touch it.”

Haibara Ai didn’t seem to notice Shimizu Koji’s intention just now, but if you look closely, there is still a barely noticeable curve at the corner of her mouth.

“I think there’s something you might be interested in.”

“Oh? What’s the matter?”

Koji Shimizu was a little curious, and Haibara Ai got up from his arms with a little effort. Although she had gradually gotten used to it and even liked this way of getting along with others, the weather was hot and humid today and she didn’t want Koji Shimizu to smell her scent when she came back from outside.

In fact, there has been such a situation before. Koji Shimizu actually said that it was a milky smell, which was very funny. It was simply nonsense. Because she has a little bit of cleanliness, she still cannot compromise on this matter.

After brushing her hair which was a little messy due to moving back and forth, Haibara Ai took out a card-sized envelope from the small school bag beside her and handed it to Shimizu Hiroji.

The envelope was pure black, and if you didn’t hold it in front of you, it would be difficult to recognize. But on the front of the envelope, the words “Dear Kudo Shinichi” were clearly written in pure white handwriting.

“This is?”

Koji Shimizu was puzzled and opened the envelope directly. The envelope had obviously been opened. There was no need to ask, because Conan must have seen it himself.

“Why does he always receive such strange things? He clears out a lot of envelopes every month. Did he find this when he got home a few days ago? Or did he just receive it?”

“It should be these two days. Kudo said that he received the same invitation letter from the Maori detective, so he thought of asking me to check the mailbox.”

“Oh, you’ve seen it already?”

“No, Yukiko opened it.”

Koji Shimizu was a little surprised, but he still read the content of the letter first. When he opened the letter, it was also pure black with gold outlines, and its design looked like a funeral invitation.

“I admire your wisdom and specially wrote to invite you to my house.”

Although it had some shaggy hair, it was indeed an invitation letter, and the signature was as expected a bit strange, signed “Twilight Villa”.

“There was originally another check, but it was taken by Yukiko.”

“Well, it’s something she would do, but if it’s just a check, it won’t have much of an impact.” Shimizu Koji wasn’t sure. Yukiko was naturally childish and lively, and this personality trait seemed to have become more serious because of her pregnancy.

His relationship with Yukiko was still lukewarm during this period, but he could also feel that Yukiko had some feelings for him.

Regardless of whether he is younger than her, or likes his skills, body, appearance, personality, etc., in short, he is somewhat attractive to Yukiko, but because of worldly constraints, Yukiko still restrains herself, and he still needs to find opportunities to continue to promote their relationship.

Chapter 545 Is this okay?!

“Is there anything wrong with this invitation?”

Koji Shimizu didn’t think he would be interested in this thing. It was obvious at first glance that it was something with bad intentions. Either it had a grudge against Yusaku Kudo or Shinichi Kudo. Considering that Kogoro Mori also received an invitation, it could be speculated that it might have a grudge against the detective.

It’s not surprising that he thought so. After all, he had lived in Kudo’s house for half a year, and similar situations had happened before.

Especially after Conan moved to Mouri Kogoro’s place, Shimizu Koji could see Mouri Kogoro on the news almost every two days, so he no longer likes to watch the news. After all, it’s all about that creepy old man, what’s there to watch?

Haibara Ai didn’t say anything, but took out two printed documents from her little red schoolbag.

Koji Shimizu took it and what came into view was a manor villa that looked eerie, ancient and solemn at dusk. It was located on the edge of a cliff and surrounded by dense jungle.

“I looked up some information.” Haibara Ai paused, seeming a little hesitant, but before coming, she had thought about it for a long time. She still came, so she would tell Shimizu Koji everything she found out.

“This manor, called Twilight Villa, was once the property of the Karasuma family several decades ago. Or, to be more precise, it was the villa of the wealthy Karasuma Renye.”
