"Tsk." Matsumoto Kayoko tugged at Yamamoto Azusa's hand soothingly, and the irritable little golden retriever managed to suppress his temper and gave a time period, "Half an hour."

"I went in once at half past twelve," Kayoko Matsumoto has stopped crying now, but her face looks haggard.

It seems that the death of her husband this time was quite a blow to her.

But she still explained in a gentle tone, "I went to bring food to Yamamoto. He has no concept of time when he is creating."

Finally, it was the assistant Ikawa Yamagami's turn. He said, "I entered after Mr. Yamamoto entered, and stayed for about twenty minutes."

"Because his last work was unsold, he was very dissatisfied with me as the assistant who introduced him to the publishing house." Ikawa Yamagami lowered his head, looking a little ashamed of this.

Conan looked at it carefully, but felt something was wrong.

But when he looked at Ikawa Yamagami's guilty expression, he couldn't figure out what was wrong.

He looked around, trying to figure out where the dissonance came from, and then he saw the guy.

The guy with the exact same face as him.

Kudo stood in the corner of the room. He looked down for a while, then bent down and picked up a photo from the gap between the closet and the wall.

Inside was an intimate photo of a man and a woman - the woman was Kayoko Matsumoto herself.

The other man was not the deceased Yamamoto Kazuhiro, but a younger and more handsome stranger who was hugging Matsumoto Kayoko's shoulders affectionately.

Conan's pupils shrank when he saw the photo. He ran over to pull the photo down and looked at it carefully. "Is this...cheating?"

Did Kayoko Matsumoto cheat on her husband?

Kudo was not angry when Conan rudely snatched the things in his hands. Now when he heard Conan's guess, he shrugged without comment.

Who knows?

Toru Amuro noticed the movement here, but he ignored the two of them for the time being. Instead, he walked to the table and put on a serious investigation look.

Okiya Subaru was standing next to the corpse with his hands folded, thinking about something.

Suddenly, Toru Amuro's eyes lit up.

He took a piece of paper to wipe off the stain on the table, then put it in front of his eyes and looked at it carefully.

...mold stains.

Amuro raised his eyes imperceptibly and looked around at the expressions of everyone.

The deceased's wife, Kayoko Matsumoto, was standing farthest away from the deceased, her eyes dull and her whole body trembling slightly.

The deceased's son, Azusa Yamamoto, was standing beside his mother, holding her shoulders to prevent her from sitting on the ground. He was still smoking, and his face did not show any sadness about the death of his biological father.

The deceased's assistant, Ikawa Yamagami, was a little fidgety and kept wiping his sweat. Looking at the active "little detectives" on the scene, he seemed a little dissatisfied, but also seemed a little... scared?

Toru Amuro paused, narrowed his eyes uncontrollably, and quickly lowered his eyes to look at the mold stains on the paper.

Who could it be?

"What did Amuro-nii find out?"

The corner of his clothes was tugged.

?

When Toru Amuro looked down, he saw the elementary school student Detective Conan looking curiously at the tissue in his hand.

"Stain." Amuro Toru bent down to show Conan the tissue in his hand, "It's on the right side of the body, and also on the cuffs."

Conan is a boarding student at the home of his nominal teacher, Kogoro Mori.

He is a very smart kid. Even if he doesn't have the character of "Toru Amuro", he is willing to help the little detective grow up slowly. :,,.
