As a result, even Edogawa Conan is like this now.

Mao Lilan sighed, and only regretted that Kudo Shinichi, who had led Edogawa Conan astray, was not in front of her, otherwise she would have to let him see her strength as the national karate champion.

Edogawa Conan has no idea what is waiting for him in the future.

He slept so soundly that he didn't even hear Ran Mouri calling him from outside the door.

It was not until a loud "bang" woke him up from his sleep that Edogawa Conan sat up in a daze, and at the same time felt the stuffy temperature in the room.

"What's going on? Could it be that the air conditioner in this room is broken too?"

He complained as he climbed out of bed, but the next second, his eyes were fixed on the door.

That is...

Mr. Ishikuri? !

Conan Edogawa hurried over and saw Ishikuri Saburo lying on his back on the ground, his body covered in blood. There was a large vase on his left shoulder, and there was also a lot of blood on the vase.

At first glance, it seemed that the vase fell from the shelf and hit Ishikuri Saburo who was standing in front of the shelf, causing his death.

but……

Edogawa Conan stretched out his hand and lightly touched the blood on the ground.

The blood has dried.

And he happened to wake up after hearing the 'dong' sound.

Judging from the situation at the scene, the loud noise was undoubtedly caused by the vase falling.

So this shows that the time of Ishikuri Saburo's death is not the same as the time when the vase fell.

but……

Edogawa Conan's gaze slowly moved from the closed window to the locked door in front of him.

Through the door, he could hear a noise coming from outside the house, as if someone was calling Ishikuri Saburo's name.

Faintly, he could hear someone saying that the key to this room had been lost since last night...

so……

His eyes gradually narrowed.

This is another closed-room murder case.

And the key was probably hidden by one of those three people?

So it seems that the murderer must be that person, right?

Only she could hide the key, and only she could ensure that Mr. Ishiguri would be able to live in the room with the trap.

But how did she kill him?

Edogawa Conan was thinking, but before he could figure it out, his train of thought was interrupted by a "click" sound from his ear.
