Refuse to allow Conan to join the main storyline

Laugh? Maybe I couldn't help it a little.

Sister Bei has really sharp eyes.

Koizumi sighed in his heart, and the micro-expressions on his face immediately restrained, the corners of his mouth sank, and he responded sharply: "Really? But you, Miss Urata, after listening to Officer Tanaka's description and seeing such a scene, can still observe others calmly. This mentality is really amazing."

Nurse Guatian said angrily, "You, why are you so fierce? I won't accompany you anymore. I have to go back to work."

After saying that, she stomped her feet, twisted her waist and walked away quickly.

Kudo Yusaku glanced at her back suspiciously, but quickly looked away and asked, "Can we go in and take a look?"

Matsumoto Kiyonaga: "Of course. The survey has been completed, you all come in and take a look. Megure, you continue."

Officer Megure, who was called, led everyone to the window and said, "We found several suspicious points when we were investigating the scene."

Inspector Megure pointed to the human figure outlined with white chalk on the ground and said, "When we arrived, the victim was lying here, and the window was open. We can conclude that the murderer broke in through the window. But..."

He pointed outside the window: "We didn't find any traces. No footprints, no handprints."

Not to mention any traces of humans, there wasn't even any trace of a cat, as they were all covered by the dust from the storage space.

Xiaoquan slowly moved over and stretched out a finger to wipe the window frame, which was covered with a layer of dust. She twisted her fingers lightly and said nonchalantly, "It's so dusty? How long has it been since you cleaned it?"

Little Kudo followed her example, standing on tiptoe and reaching out to touch the windowsill.

He looked at the dust on his hands, his eyes rolled around twice, and he ran away. But within a minute he came back and shouted excitedly, "There is not so much dust on the windows of Sister Sakurai's ward!"

"Eh?" Megure Jusan was stunned for a moment, frowned slightly and said, "Well, this is indeed a suspicious point that we didn't find."

Koizumi glanced down at Kudo Shinichi and saw that the brat was sticking close to her again, looking up at her with a smile.

Koizumi: ...

Why don’t you go learn how to solve cases from your famous detective dad, but instead stick to me?

Koizumi ignored him and continued standing by the window looking out.

Oops, it was too dark last night and I didn’t notice it. There was a vague cat’s paw print on the waistline. It was a close call!

As soon as she thought about it, the footprint was covered by even thicker dust.

Very good, I'm sure there are no more loopholes.

After destroying the only evidence at the scene that might be unfavorable to her, Koizumi naturally looked up and said, "This building has eight floors in total, right? Have you checked upstairs?"

Inspector Megure was stunned: "Upstairs?"

Kudo Yusaku nodded in agreement: "If the criminal used a steel cable to drop vertically from above, it is indeed possible."

Officer Narita looked at Koizumi in surprise. He didn't expect that the top suspect in his mind was actually helping them solve the case and giving them a lot of useful suggestions. He immediately turned around and ordered, "Tanaka, take your men to the rooftop to check immediately."

"Yes."

Koizumi: "Not just the rooftop, but also the sixth, seventh and eighth floors. Check to see if there are any footprints on the exterior walls and window sills, or any traces of friction from things like steel cables."

Officer Narita: "Yes, check it carefully for me!"

"Yes!"

Kudo Yusaku's attention was more focused on the outline of the human figure on the ground: "It's winter now, especially at night it's very cold. The wind was quite strong last night. Most people wouldn't open the windows for no reason."

Hearing him say this, Koizumi understood Kudo Yusaku's idea and casually checked the window lock: "This window should only be opened from the inside, and it doesn't look like it has been damaged."

Although Inspector Megure tried hard to follow their train of thought, he still felt a little overwhelmed. He frowned and touched his chin and asked, "Well, what does this mean?"

"It means the window was opened by the deceased himself!"

Little Kudo answered the question successfully.

Koizumi smiled and praised, "Smart. Then why did the deceased open the window by himself?"

Little Kudo: "Because... because there is something outside the window that interests him!"

Koizumi nodded and continued to ask: "Then what would he be interested in?"

"Eh..." Little Kudo was stuck.

Kudo Yusaku reached out and touched his son's head. "Maybe the person outside the window is someone he's interested in? Isn't Sakurai-sister's suggestion to search upstairs a proof of this?"

Little Kudo nodded seriously.

Koizumi glanced at the three policemen next to him. Matsumoto Kiyonaga had a poker face and no expression, while Officer Megure and Officer Narita had the same expression of being taught as Kudo, which was quite funny.

Kudo Yusaku continued: "The deceased saw someone he was interested in, or someone he was familiar with, which made him open the window without any defense."

Officer Narita muttered to himself, "An accomplice, it's his accomplice! He's the murderer who committed more than ten murders in a row! He's also the real owner of the shotgun!"

Yusaku Kudo: "Officer Narita, when you say a dozen or so murders, do you mean the serial murders during this period?"

Officer Narita sighed, "Yes. I'm afraid Mr. Kudo has heard that there is a new force in Tokyo recently. This force is very dangerous and has a large number of people. It has committed 24 murders in seven days, but they are all targeting drug dealers hidden in Tokyo. The police also seized a lot of contraband."

Koizumi narrowed his eyes slightly.

Seven days, twenty-four? Gin is not idle either.

It seems that the gunshots I heard on the day of the surgery to remove the bullet in my lower back were caused by him? I don't know how many people he killed besides the drug dealers, and whether Rum's losses were great.

"Especially in the first three or four days, their actions suddenly accelerated, and a criminal who can be called extremely dangerous appeared. This guy always killed people with a shotgun, and then cleaned up the scene in an orderly manner, leaving no trace for the police. He even took the initiative to call the police after each murder, and then left calmly. His methods were extremely cruel, and his mentality was extremely stable. He was a very dangerous guy!"

Koizumi: ...

Now that you put it that way, it seems to make some sense, huh?

She coughed lightly and said, "Officer Narita, is this the person you said looked very similar to me?"

Officer Narita coughed awkwardly and said, "Yes."

"Besides the five people from last time, are there any other witnesses?"

"……No."

Koizumi: "...Well, that's what I'm saying. Is it possible that he was just a random passerby?"

Seeing that she had attracted everyone's attention, she gestured her height and said, "Not to mention that there are actually quite a few people dressed like this. And according to what you said, this person is 1.7 meters tall and doesn't look very strong. But who are the drug dealers?"

She pointed to a particularly large humanoid mark on the ground and said, "They are usually strong, cunning and cruel, right? And they usually carry dangerous weapons. Do you think someone with my physique can beat them? Just like the last time I met Nigawa Takashi, I could only control him temporarily and wait for Inspector Megure's support. So I want to say, aren't the characteristics of this suspect a little unreliable?"

Officer Narita: ...

Now that you put it that way, it seems to make some sense, huh?

Kudo Yusaku coughed lightly and said, "I have heard about the Daikoku Bar from Manager Matsumoto. According to my speculation, the brutal suspect you mentioned is very likely the murderer of the deceased. Last night, he first sneaked into the power distribution room on the fifth floor and installed a time bomb. Then he used some means that we have not confirmed yet to get outside the window and knocked on the deceased's window. When the explosion occurred in the power distribution room and the police guarding outside were attracted away, the murderer shot and killed the deceased. Our deceased was not on guard against him because they knew each other, or were acquaintances. The deceased may have thought that the other party was here to rescue him, so he was not on guard."

Koizumi: ...

Thanks to Mr. Kudo for helping me confirm the connection between Tequila and drug dealers. Now I won’t have anything to do with it anymore.

"Sorry, I can't hold on any longer. I'm going to go back and rest first."

Koizumi hunched over, interrupted in a weak voice, and walked towards the door, holding on to the wall.

Hibiki Eri had been listening carefully to everyone's analysis. At this moment, she suddenly realized that this person was still a seriously ill patient. She hurried forward to support her: "Are you feeling tired? I'll help you back."

Koizumi dragged his feet and walked out with his head down.

When she reached the door, she suddenly stopped, turned around and waved to Kudo Shinichi.

Since she had performed quite well in analyzing the case just now, Kudo ran over to her and asked with his head tilted up, "Sister Sakurai, what's the matter?"

Koizumi said nothing. He pointed to a shallow mark on the ground, then to a less obvious handprint by the door, and finally to the door of the ward: "This is another truth of this case. I leave it to you."

After saying that, she waved her hand weakly and left.

Little Kudo was feeling a bit bored, but his eyes suddenly lit up after hearing Koizumi's suggestion.
