It wasn't until dark that the uncle came out of the factory's dormitory, hailed a taxi on the side of the road and left.

Katayama just came out of the corner, he had been guarding for hours, and this girl finally gave up.........

He actually wanted to sneak in to find out what secrets were hidden there, and the iron door wouldn't stop Zorro from unlocking the lock anyway, but he was worried that the man would find out that he was inside.

Then as soon as he found the clue, he felt that there was someone behind him, and finally he couldn't take care of himself after being smashed by a hammer.

This is a common episode of unauthorized action in manga and animation, and he can't let such a bloody thing happen to him.

So he deliberately waited for the man to leave, and then ran into the factory dormitory again.

It's still in the nineties.,Cameras.,There's a camera.,But there's only one gate.,Katayama quickly found the blind spot of the camera under the leadership of Zoro.,And then turned in.。

Along the way, there are quite a few employees still there, some are preparing to go back to the dormitory to rest, and some are taking a walk.

However, he has always been an inconspicuous type, so few people have noticed him.

Even if you notice it, you guess you'll think he's a new employee.........

………

Click————

With a crisp sound, Matsudaira Masako's door was opened by Zoro, and Katayama cautiously walked inside, closing the door just in case.

Turning on the flashlight of his mobile phone, he began to observe the inside of this room, which was full of dust and cobwebs, it was indeed a long time since anyone lived in it, and it was basically a normal empty room.

There was another click, and Sana Mizuhara's room was opened, but again, there was nothing suspicious at all...... But if so, why was the man almost ready to kill him?

He walked out of the room and closed the door.

He looked at the iron door between the two rooms.........

Click————

Just as he was still thinking about whether there was a need to enter this place, Zorro had already unlocked the lock and walked in by himself.

"You ...... guy"

Katayama grumbled and followed in.

The room type is exactly the same as the two rooms just now, but there is always a kind of indescribable depression here......

"It's weird, there's a lot of wrapping paper ...... here"

Katayama's flashlight shines into a corner and he finds a small pile of glowing wrapping paper.

He walked over and squatted down to take a closer look, it was some small snack wrappers, chocolates, biscuits and the like, which seemed to be ......

Wrong...... The two houses had not been inhabited for a long time, but there was no such garbage piled up in them.

Could it be that someone has been here for a snack recently?

Probably not, the dust on the wrapping paper doesn't pile up like that in a few years.........

"Huh?"

At this time, the flip phone rang, and then it fell silent again, which was the prompt tone of the text message, indicating that Conan should have found the information.

He quickly turned on his phone...... looked at the message inside...... It's a photo of an old newspaper......

"Hanging ........."

Katayama quickly browsed the news, and here it is about a woman with mental problems because of her husband's affair in the staff dormitory more than ten years ago...... After locking the iron door in room 3-5, he hanged himself, and it was not until two weeks after his death that a delivery person heard the girl inside crying for help and was found by people nearby.........

In other words, the place where he is standing now is the scene of the crime more than ten years ago?

There was so little news in the newspapers that there didn't seem to be much information.

——— had tried their best to find only so much.

Conan sent a text message, but Katayama didn't have the energy to reply to him, but thought about the connection between the hanging perspective and the two murders.........

"Meow~"

Zorro shoved a wrapper in front of him and licked his lips again.

"Bear with me a little longer, this time I won't starve you........."

As soon as Katayama finished speaking, a flash of light immediately appeared in his mind......

That kid! If her mother committed suicide...... So how did she survive for two weeks.........

"The specific murder method is also a portrayal of the murderer's heart."

Conan's previous words resurfaced......... He already roughly understood the motive of the murderer............

But...... There are still a few doubts that have not been figured out.........

…………

"Ah, it's not that simple to solve the case........."

Katayama was about to walk out of the dormitory with Zoro in his arms, but was bumped into by a drunken uncle on the way......

"Ah sorry sorry, I drank too much......"

The uncle apologized to Katayama embarrassedly, but Katayama didn't say anything, just nodded and stood up from the ground.

"Huh? Wait, you're the one who went to the old house with Matsumoto in the morning......"

The man seemed to see Katayama's appearance clearly, and suddenly said.

"Matsumoto? That man's last name is Matsumoto? ”

Katayama hurriedly grabbed this uncle, good guy, he was about to ask Conan to investigate the man, and when he was still thinking about how to describe it, he actually happened to bump into it!

"That's right, his name is Matsumoto Masa, and he is an old employee here, and I knew him very well when he was still living in the old house."

"Old house? Referring to the old building, right? ”

Seeing that the uncle nodded, Katayama immediately asked anxiously.

"Excuse me, which dormitory did Mr. Matsumoto live in at the time.........

"Ah...... If I'm not mistaken...... It should be the third floor...... Ah, it seems like 3-5, right? ”

“！”

Katayama broke out in a cold sweat.........

"Although it's not big inside, it's barely enough for a couple to take care of children......"

Matsumoto's words in the morning appeared in Katayama's mind......... Boy! Boy!

He's a 3-5 householder! That bastard man who killed his wife to commit suicide!

If he's not lying, he's supposed to be a freight truck in Tokyo............ Now everything makes sense!

………

"I'm back~"

Katayama hugged Zorro and walked into the café listlessly, he had been busy all day, he hadn't eaten anything, and his stomach was almost hungry.

"Come on, please eat this."

A chocolate bar was handed to him, and because he was really hungry, he took it and bit into it without even thinking about it.

After regaining a little strength, he remembered that the words just now did not look like Yukiko's voice.

He hurriedly looked up and saw that it was Matsumoto Ju standing in front of him?!

"You put Yukiko?"

"Shhhh

Matsumoto said with his finger against Katayama's mouth.

"Mr. Katayama hasn't eaten anything in a day, has he? It's not good to be hungry, do you want to try my craft~"

Katayama looked at Matsumoto with a smile on his face...... Sighing helplessly.

"Okay, will you go to your house?"

"Well, just the two of us."

"It's fine."
