The luxurious hotel room should have been a comfortable and enjoyable environment, but at this moment it was a bit cold.

This is no wonder. After all, the former resident of this room, Itakura Taku, has now fallen to the ground, covering his chest with his hands in pain, saliva flowing from the corners of his mouth, and has become a cold corpse.

"He's been dead for more than a day." After examining the body, Maori Kogoro sighed and said, "There's no hope of saving him."

"Lan Sang, please call the police." Tang Ze turned around and after giving Xiao Lan instructions, he pulled out a pair of white gloves from his pocket and said, "From now on, I'll be in charge of this place."

"I understand." Xiaolan had also experienced a lot. Although she still felt a little uncomfortable after seeing the dead body, she quickly followed Tang Ze's instructions, took out her cell phone and went outside to call the police.

Conan, who was standing by, looked at Itakura Taku's cold body with an expression of unwillingness on his face.

After finally getting a clue, when we found the person, he was already a corpse. The feeling of failing at the last minute was not pleasant.

What worried him even more was that the other party was killed by members of the Black Organization. If that was the case, he would most likely get nothing.

Seeing Conan's worried expression, Tang Ze guessed what he was thinking and patted Conan on the shoulder, then signaled him with his eyes to look at the open handbag on the ground.

“That’s it!!”

When the disk with the word "Diary" on it came into view, Conan's pupils shrank sharply, and he wanted to reach out to take it, but the next moment Tang Ze put his arm around his shoulder.

After being stopped by Tang Ze, Conan immediately calmed down. He knew that now was not the time to take the disk, so he restrained his actions.

At the same time, Conan was also glad that he called Detective Tang Ze over, otherwise it would be very troublesome to get the disk.

"how so!"

Naito Sadahira, who was frightened by the corpse and sat paralyzed on the ground, came to his senses and looked at Itakura Taku in disbelief and said, "How could he die out of nowhere..."

"I think it's a heart attack..."

Maori Kogoro looked at the medicine scattered beside the computer and said, "I'm afraid the heart attack was very rapid. Mr. Itakura, realizing that something was wrong, wanted to go get some medicine, but even then it was too late and he died.

It’s just that Mr. Itakura had been dead for more than a day, so the hotel staff should have found the body while cleaning the room…”

"Ah, this may be because Mr. Itakura hates others, maybe there is a place where he works..." Naito Sadahei explained after hearing what Mouri Kogoro said.

"Yeah, there was one time when a book on his desk was only moved about 10 centimeters, and he flew into a rage over it." Xu Bakerlu echoed, "He's so sensitive he's a little neurotic..."

"After all, he only changes his own bedsheets every six months." Soma Ryusuke also spoke up after hearing what the two said, "So I guess he directly instructed that hotel staff not to enter his room..."

"Hmm... Is that so?" Maori Kogoro looked down at the corpse and said, "It seems that suicide is more likely..."

"Don't jump to conclusions yet."

As Tang Ze examined the body, he said, "If it's true, as Detective Maori said, that the messenger's death began with a heart attack, then there are some unusual places on the body."

"Eh?" Maori Kogoro was startled when he heard that. He immediately looked at the corpse and asked, "Where?"

"The back of the hand." Tang Ze picked up the hands that Itakura Taku had placed on his chest and said, "When we came in, the deceased was lying on the table with his hands covering his chest.

If Itakura Taku really died of a heart attack at the table, his hands covering his chest should have been clamped between his chest and the edge of the table.

In this case, there should be traces of accumulation on the back of the hand, but..."

"Mr. Itakura's hand has no signs of post-mortem pain from being pressed against the edge of the table!"

When Maori Kogoro saw the clean back of the corpse's hand, his expression immediately turned serious, "Could it be that Mr. Itakura died somewhere else?"

But this is a bit strange. Judging from the stiffness of the deceased's hands and feet, Mr. Itakura did die in that posture.

If he wasn't lying on the table, with his hands not clamped between his chest and the edge of the table, his hands should have hung down naturally.

And look at his feet. If he wasn't sitting on a chair, they wouldn't be bent like this.

But if someone tied Mr. Itakura to the table..."

Maori Kogoro was stunned when he said this, and suddenly looked down at the corpse below, "If it is tied up... then..."

"That's right..." Tang Ze nodded and said, "I'm afraid it's a murder case."

At this point, Tang Ze reached into his backpack and took out a disk labeled "Diary" and a blank disk. He handed them to Conan and said, "Conan-kun, can you help me plug this disk into the computer and see if there is anything useful in it?"

"Hey, hey...Detective Karasawa, don't leave such an important matter to a little kid like you." Kogoro Mouri muttered.

"Don't worry, it's okay." Tang Ze smiled and said, "Conan is very proficient in using computers."

Without waiting for the other party to say anything, Tang Ze quickly said, "By the way, Detective Maori, do me a favor. I want to check if there are any signs of being tied up with ropes on the body."

Karasawa's words diverted Kogoro Mouri's attention, causing him to unconsciously ignore his previous thoughts and begin to cooperate with Karasawa to undress the corpse.

There were no obvious rope-shaped spots on the body, indicating signs of restraint, but slight bruises caused by external pressure could be seen from the shoulders to above the knees.

"It seems the criminal was quite clever. He even used the blanket as a cover before wrapping Mr. Itakura's body. Then, he simply stuffed a pillow between his chest and thighs to keep him in place."

Tang Ze stood up and said, "Detective Maori, please check if there are any signs of binding on the legs of the table and chairs. I'll go check elsewhere."

"No problem, leave it to me." Kogoro Mouri nodded, and immediately began to carefully check the table legs around him.

After Tang Ze determined that the case was a murder through a series of reasoning (plot analysis), he walked towards the direction of the chessboard.

And here lies the decisive evidence.

All the previous actions were just to make things go smoothly.

"Karazawa-kun, even though it was torn off, there are still some traces of tape on the table legs..." Maori Kogoro's voice sounded from behind, "It seems that this is indeed a murder case, but the criminal..."

"I already know the true identity of the criminal." Tang Ze said with a smile, "And the evidence is conclusive."

“What!?”
