Last night around half past ten.

At that time, because Congressman Yamazaki suddenly stopped attending the Young Hospital Association, Ishida Takaji, as his bodyguard, naturally followed him back to the Lily Hotel.

Of course, as a bodyguard, he was guarding outside the room and did not go in.

However, at around ten o'clock, the congressman informed him that he could go home first. When he was about to go home, a friend suddenly called him, and he started chatting with his friend in front of the elevator.

Then he saw a woman entering the congressman's room. The congressman opened the door himself. After confirming that no one saw them, he hugged the woman wearing a hat and went into the house.

This time is around half past ten.

Unfortunately, because the other person was wearing a hat, he didn't pay much attention when she walked out of the elevator. When he saw her enter the congressman's room, only her back was left, so he didn't see the woman's face.

"What about your height?" Tang Ze asked after hearing this.

"It should be around my neck." Ishida Takaji gestured. "It should be around 1.6 meters, a very common height for a woman."

"Hey, hey... there were witnesses who said they saw a burly man about 1.8 meters tall leaving after Councillor Yamazaki's estimated time of death."

Naoki Kamii looked at Ishida Takaji with suspicion and questioned, "Are you deliberately throwing out a fake character to confuse our search because the police suspect you?"

"Humph! I already told you that there's no way I'd kill Councillor Yamazaki!"

Upon hearing this, Ishida Takaji glared at Kamii Naoki and said, "If you doubt me, you can take me back to the Metropolitan Police Department!"

Naoki Kamii ignored him and looked at Tang Ze and whispered, "What should we do now? Should we take him back?"

But if his testimony is correct, then the case becomes even more confusing..."

The young waiter said that the last person he saw leaving was about 1.8 meters tall, but Ishida Takaji said that the person who entered the hospital room half an hour before the incident was a woman about 1.6 meters tall.

It is obvious that one of these contradictory testimonies is wrong, and the young waiter has no relationship with the congressman, so naturally the bodyguard Ishida Takaji is worthy of suspicion.

"No, after listening to Mr. Ishida's words, I was convinced that this was not a conspiracy from Nagatacho, but a simple emotional entanglement between a man and a woman, and it was a sudden murder without premeditation."

"Eh? A love affair between a man and a woman? A murder in the heat of passion?" Naoki Kamii was surprised when he heard what Karasawa said. "Why is that? Senior, why do you feel that way?"

"Before Councillor Yamazaki was murdered, all his phone contacts were women. Haven't you noticed anything yet?"

Tang Ze smiled and reminded: "Don't forget, Councillor Yamazaki is currently at the center of the "storm".

He's currently investigating illegal fundraising, yet he's even hired bodyguards. Do you think such a cautious person would casually let a stranger into his room?

"Now that you mention it...it's very likely that the crime was committed by an acquaintance..." Naoki Kamii said suddenly.

"No, I'm not jealous. And don't forget that Councillor Yamazaki's schedule suddenly became free yesterday."

Tang Ze said: "He suddenly didn't attend the party he was originally going to and chose to return home. If he was a professional killer, it would make more sense for him to act at the party according to his previous plan.

This sudden change further suggests that the criminal was suddenly summoned to Councillor Yamazaki's room."

"So, the suspects are the three women who had phone contact with the deceased before the incident!?"

After finishing his words, Naoki Kamii felt something was wrong and immediately said, "Wait, if that's the case, then what about the testimony we heard from the waiter?

He said he saw a tall man who was 1.8 meters tall. Is he lying?

"Yes, it's a good thing to have your own thoughts."

Tang Ze praised the other party and immediately answered the question he raised: "Regarding this point, I believe that the woman witnessed by Mr. Ishida and the man seen by the waiter are the same person!"

"But that's a difference of nearly 20 centimeters!" Naoki Kamii said puzzledly, "And just now, Senior, you said that this was an unplanned, sudden murder.

If he wasn't fully prepared, how did the criminal manage to disguise himself as a tall man around 1.8 meters tall?

"Because the criminal used the shoes from Councillor Yamazaki's room to complete the purpose of disguise."

Tang Ze's words made Ishida Takaji a little confused: "My Detective, if you said that the criminal was wearing high heels, then I can understand it, but Councillor Yamazaki is a man, and he doesn't have strange hobbies like transvestite.

I've been following Councillor Yamazaki's side recently, so I can guarantee this!"

"No, you misunderstood." Tang Ze explained with a smile: "I'm talking about another kind of unisex shoes, hidden height-increasing shoes, which are also the key to solving this case."

"So, Detective Karasawa, are you saying that after killing Councilman Yamazaki, the criminal put on his hidden height-enhancing shoes and disguised himself as a man before leaving the room?"

Naoki Kamii stroked his chin and said, "Although it's theoretically possible, it's probably too smooth."

"That's right. And whether or not Councillor Yamazaki actually has height-increasing shoes is another matter."

"Take out the criminal manual where you recorded your testimony and look through the testimony of the female college student, Sumiko Koonaka, and then think about what Mr. Ishida just said."

Tang Ze reminded him, "Don't you see the connection between not going bowling, not going to high-end Japanese restaurants, and not playing golf?"

"Ah!! You all need to take off your shoes!!" After being reminded by Tang Ze, Naoki Kamii, who was quick-witted, quickly found the common point between the three.

"That's right. Councillor Yamazaki doesn't touch these places, and you need to take off your shoes. But if you take off your shoes, your true height will be exposed. That's why Councillor Yamazaki avoids these places and even gets angry at students who suggest going bowling."

Tang Ze looked at Naoki Kamii who was lost in thought and patted him on the shoulder: "Don't think anymore, the next lesson I will teach you is to verify!

When you have a certain idea in your reasoning, you should find a way to verify its authenticity so that you can verify whether your idea is right or wrong.

If the reasoning is correct, then using this basis to carry out the next step of reasoning, just like solving a math problem, you will eventually find the only correct answer.

After saying that, Tang Ze took out his cell phone and called Uncle Dengmi.
