"What about this?" Ogino Keisuke said, reaching for the wine glass on the coffee table. "I've been drinking beer since the beginning, and the foam is still left!"

"I see." Takagi looked at the white beer still remaining on Ogino Keisuke's hand and nodded to show his agreement with his evidence.

After all, under normal circumstances, beer residue will not stay for too long. The fact that there are still some left now means that the other party is likely to have come downstairs after committing the crime.

After seeing Ogino Keisuke's evidence, everyone headed towards Tsukihara Kaori's room.

"Sister, did you also go to the funeral with Mr. Ogino?"

After entering Tsukihara Kaori's room, he found the same paper bag next to the bookcase, and Conan asked.

"Yes, all three of us attended the funeral, although the president didn't attend." Tsukihara Xiang nodded and explained.

"Did you just make this coffee?"

Tang Ze asked while looking at the coffee in the cup on the table.

"Yes, that's the coffee I just made before I left the room." Tsukihara Kaori nodded and said, "I can't work seriously if I don't drink a cup of coffee in the morning."

Conan, standing by, raised his phone to take pictures again, while Gao Mu looked at the coffee carefully and said, "This can barely be used as evidence. After all, there is still steam left on the coffee cup..."

"Mr. Criminal, hurry up! Please come in and take a look!"

After hearing Takagi's words, Kanzaki Kazutomo seemed to suddenly think of something, and hurriedly urged the two to come to his room, took out the key, opened the door and invited them in.

"Calm down first and don't be so panicked." Takagi looked at Kanzaki Kazutomo who suddenly became impatient and quickly spoke to comfort him.

"No, I just saw the steam coming out of Ms. Tsukihara Kaori's coffee, and it suddenly occurred to me that I have similar evidence!"

Kanzaki Kazutomo said as he hurriedly opened the bedroom door, but when he saw the ashtray on the desk, his tone immediately became lost: "It's over, when I went out, I put the half-smoked cigarette on the ashtray.

Now it’s completely extinguished…”

However, Kanzaki Kazutomo was still unwilling to give up, and immediately went to pick up the remaining cigarette butt.

As the long ash fell, the tiny cigarette butt actually lit up again.

"Ah, it's still burning!"

Kanzaki and Tomo excitedly held up the cigarette butt and showed it to Tangze and the others: "It was blocked by the ash just now, but you see it's still smoking, right?!"

"really..."

Seeing the smoking cigarette butt in the other person's hand, Gao Mu nodded and then looked at the three people and asked uncertainly: "In other words, none of you three went to the deceased's room, right?"

The three of them were not stupid. When they heard what Takagi said, they naturally nodded in agreement and insisted that they had never been to President Katsumoto's house.

Tang Ze looked at the three people in front of him but didn't say much.

Because he knew that one of the three people at the scene must be the murderer.

The evidence provided by these three people were foam, heat and smoke.

However, Tang Ze was not idle either. He asked Conan to use his mobile phone to record the evidence of the three people to help them preserve this timely evidence.

When Inspector Megure arrived, Takagi told him everything about what happened to Karasawa and others after he handed over his shift at 7:30, and then he encountered the three people who jumped from the building and sent text messages to find out.

As for the content of the text message that President Katsumoto sent to the group, it was a letter that provoked the recipient and urged him to kill someone.

Of course, they did not just sit there doing nothing after checking the rooms of the three people. Instead, they went to President Katsumoto's home on the 26th floor to take a quick look at the situation while watching the three people.

In the other person's home, the entrance door and the floor-to-ceiling windows on the balcony were still open.

In addition, he went to the monitoring room to check the elevator surveillance, and Takagi also climbed the stairs to calculate the time it took to go upstairs.

After checking the phone, I found that after the other party sent the text message to the group, he immediately contacted the decorator with his phone.

When it comes to reasoning, Gao Mu may be a little weak, but when it comes to investigating information, he is extremely skilled and quickly found out how the other party contacted the decorator.

It turned out that last night, the decorator went to help the president replace the carpet in his room, but the carpet was different from the one he bought.

So today, President Katsumoto was on the phone measuring the actual length of the carpet wool while complaining to the other party.

However, halfway through the call, the doorbell rang, so President Katsumoto called and said he would call back later, and then hung up.

"Hmm, so that means President Katsumoto was in his room until he fell."

After listening to Takagi's description of the case, Inspector Megure stroked his chin and said thoughtfully, "Then the person who rang the doorbell is probably the murderer."

"That should be correct." Tang Ze nodded.

"Also, I would like to ask, how long does it take to get from their room to the room where the deceased is?" Megure asked.

"Since all three suspects live on the third floor, it would take about seven minutes to get to the president's room on the 26th floor."

Gao Mu said: "I have done actual tests myself before, it should be correct."

"Climb the stairs?" Megure was surprised when he heard Takagi's words: "Didn't you take the elevator test?"

"There are cameras in the apartment elevator. I checked with the security room earlier."

Tang Ze said, "The cameras did not capture the figures of those three people around 7:30 when President Katsumoto fell from the building.
