Stay away from Conan.

Looking at the body that had fallen here, the murderer who killed Mr. Koide, the other figure who appeared in the toilet, after completing the murder, reported to the person on his phone who was obviously the instigator of this action:

"Well done, the car has been parked in the designated place."

Then, after the person on the other end of the phone replied with a clearly changed voice, the killer bent down, took the cell phone from the deceased Mr. Koide's hand, and was about to drag the body to a separate toilet in the bathroom, hoping to prolong the time for the body to be discovered so that he could leave in time. At this time, the killer keenly noticed that someone seemed to be walking towards the toilet.

Immediately, after realizing this, the mysterious killer knew that he could not stay any longer. After all, the mission had been completed. Just like that, the mysterious killer turned around and came to the bottom of the ventilation duct that had been opened on the ceiling of the toilet.

This is the key to how the mysterious killer sneaked into this place without anyone noticing.

The mysterious killer was seen to be agile. He used the toilet and the wall in the bathroom stall as leverage and quickly rushed into the ventilation duct, then prepared to leave along the duct.

At this moment, Genta and Mitsuhiko, who happened to come here to use the restroom, were in a depressed mood because of Maori Kogoro. They wanted to use the restroom and leave immediately, but as soon as they entered the restroom, they saw -

A man in a suit and tie fell on the floor of the toilet, and there was a dagger clearly stuck in his throat. Just one glance and Yuantai and Mitsuhiko immediately realized that a crime had occurred.

--"ah!"

Suddenly, after they stepped into the toilet and saw the body in the toilet, Yuan Tai and Mitsuhiko were stunned for a moment, and then they were terrified by the scene they saw. They screamed and didn't know what to do for a while. Then Mitsuhiko asked Yuan Tai with a trembling voice:

"Yuan, Yuantai, I think I saw someone over there..."

"I, I... Mitsuhiko... it seems... yes, yes, someone died... right?"

Yuantai also spoke to Mitsuhiko very nervously.

"Well, it seems... yes..."

Mitsuhiko was so nervous that he didn't know what to do. He and Yuanta just stood at the door in panic for a moment. Somehow, after they reacted for a moment, they screamed loudly -

"what--"

--"Um?"

So, when Mitsuhiko and Genta screamed, Conan, who was secretly observing the situation around Kogoro Mouri not far from where they were, immediately noticed the screams of Mitsuhiko and Genta.

So, subconsciously, although Conan didn't know what happened, he was so perceptive that he didn't even bother to continue observing the situation around Maori Kogoro, and directly followed the source of the scream -

Run towards the toilet on the fourth floor.

"You guys! What happened!?"

When Conan arrived at the bathroom door on the fourth floor, he saw Genta and Mitsuhiko standing at the door in a daze, trembling with fear and not daring to go into the bathroom. Conan felt that the situation was very bad and asked anxiously.

As a result, before Yuantai and the others could react and find Conan was actually here, and before they could answer Conan's question, Conan had already run to the door of the bathroom. Following the direction of their sight, Conan also looked into the bathroom, and then immediately saw the body of the man lying in the bathroom - "What!"

In this bathroom, the first thing that caught his eye was the man lying on the ground, and obvious blood was flowing around the man. For a moment, Conan still had some hope that there might be a chance to save him, so he calmed down and ran into the bathroom to start checking the condition of the deceased.

However, it was obviously too late. The man's throat was pierced by a dagger and he was no longer alive.

but……

"From the look of the body, he didn't die for long, maybe only a few minutes..."

Noticing the condition of the body, Conan immediately determined that the death occurred not long ago, so he hurriedly looked around the other partitions in the bathroom to see if there was anyone there. At the same time, he anxiously asked Genta and Mitsuhiko at the door:

"Mitsuhiko! Genta! Did you see anyone when you came here?"

After some searching, there was no trace of other people in the bathroom. Conan thought that if the murderer committed the crime not long ago, then when the murderer left, he might have run into Mitsuhiko, Genta and others who had just arrived here and discovered this scene, so it was very likely that they would see the murderer's appearance.

But, obviously, Conan thought things were simple.

When faced with Conan's loud questioning, Genta and Mitsuhiko, who were frightened and at a loss because of the scene before them, finally came to their senses. In response to Conan's question, they were a little confused at first and said "no". Then, after Conan saw that they were not in a good state and asked another question, they finally calmed down completely and said to Conan affirmatively:

"No! We didn't run into anyone when we got here!"

Suddenly, hearing this, Conan couldn't help but look solemn -

Isn't that such a coincidence?

Conan felt a little regretful that Genta and Mitsuhiko didn't run into anyone else, and then he looked at the death of the deceased and couldn't help but wonder in his heart -

The victim didn't even show any resistance when the knife pierced his throat so cleanly. Isn't this action too professional? Could it be that the murderer was a professional killer?

So after thinking for a while, when Conan was about to ask Genta and Mitsuhiko to ask Maori Kogoro to deal with it, he suddenly discovered -

The entrance to the ventilation duct on the ceiling of the bathroom was actually open!

——Could it be!

"Genta! Mitsuhiko! Go call Uncle Mori! Call the police immediately!"

Conan urgently gave orders to Mitsuhiko and Genta, asking them to quickly call Maori Kogoro who happened to be at the scene to deal with the situation.

"okay……"

So, after hearing what Conan said, the two of them ran away in a hurry.

Then Conan, who stayed here, came to the opening of the ceiling vent, looked at the height of the ceiling, and then activated his foot-strengthening shoes... (End of this chapter)
