When the first responders carried away Kunyou, Henggou was still inspecting the room on the third floor with everyone, and no suspicious person was found.

Gao Cheng stood in the corridor at the door with his hands in his hands, silently watching everyone search room by room.

If the case is not solved as soon as possible, the next person who may be killed is Mrs. Kunitome, one of the top 3 survivors of the 13.

No matter what the truth of the shipwreck accident 13 years ago is, the murderers cannot be allowed to continue to act recklessly.

It is at least certain that one of the families of the four victims was a prisoner......

Xiao Ai has been following Gao Cheng's side, wearing a hat in a low-key manner, coupled with a ponytail hairstyle, even people who know how to make small pills can hardly think of Miyano Shiho, but Xiao Ai himself is still very concerned about the appearance of the members of the black-clothed organization.

Looking at Gao Cheng, who was thinking, Xiao Ai also tried his best to put away his distracting thoughts and help find clues.

"At that time," Xiao Ai suddenly spoke, "when Mr. Guoyou replied, there were other voices mixed in the walkie-talkie, the sound of knocking on the door and the sound of opening the door, and then Mr. Guoyou let out a miserable scream, it should be that time when he was frightened and had a heart attack......"

"I think so too, the reason why I asked Mrs. Kuniyou to wait at that time was because I was already preparing to meet someone, that is to say, Mr. Kuniyou himself let someone go to the third floor......"

Gao Cheng's gaze swept over the entire bedroom, personally experiencing the prisoner's performance when he opened the door.

"The key is what Mr. Kuniyou saw, the prisoner just opened the door and he was so frightened that he had a heart attack......"

"The soul of the fifth," Xiao Ai whispered with his hands behind his back, "that's what it says on that card, isn't it?" ”

"The problem is that only four people were killed 13 years ago."

Gao Cheng walked to the internal phone next to the bed, which is the place where Guoyou Chunda talked to the outside before he had a heart attack.

The telephone is connected to a fingerprint reader, which can be operated to make calls and open the door, and can even actively manipulate the alarm, which is not too close to the door of the room through a bed.

Kunyou Junda should have been sitting on the edge of the bed talking to the door before he let his wife wait when he heard a knock on the door, and he had a heart attack when he looked back at the door.

The soul of the fifth man...... Could it be that there were still people who survived the accident that year?

Gao Cheng sat on the edge of the bed on behalf of Guoyou Chunda, and when he turned around, he saw Xiao Ai standing straight at the door with his eyes open, looking concerned.

"Don't worry," Gao Cheng smiled, got up and said, "I'm no longer the rookie who was helpless when he encountered the case, although this case is a bit complicated, but the biggest mistake of the criminal is to commit the crime in front of us, and he didn't have time to deal with all the traces perfectly." ”

Since coming to Guoyou's house, things have not been too smooth, several so-called supernatural phenomena have been too long, and no clues can be found at all, and then a death case occurred under the nose, and even the employer had a heart attack and saw that there was no help.

I don't know if Conan's aura of death is too powerful, or if the murderer really doesn't take him as a detective seriously...... Either way, that's the end of the case.

"No suspicious characters were found," Yokozo returned to Gao Cheng's side with some disappointment, "The entire windows on the third floor are locked from the inside, and there is no trace of any prie...... But because of Conan, the prisoner couldn't escape from this balcony......"

Gao Cheng looked at Henggou and the few people from the Guoyou family who were following behind, and did not express his opinion.

"So there's only one possibility," Yokogou continued somewhat helplessly, "it's that the prisoner deliberately opened the door to let us in before Conan climbed up, and then hid somewhere on the third floor, taking the opportunity to blend in with us......"

"How is this possible?"

The fat butler panicked: "Are you saying that the prisoners are among us?" ”

"But we all heard the sirens to get here!"

"Yes, I came in after the officer......"

"This," Henggou said with a headache, "Actually, I only remember that Madame has been following us, and it was so chaotic at that time, and we were all in a hurry to find Mr. Guoyou, it was difficult to notice if anyone had mixed in, and it was ......"

Henggou glanced at the calm Gao Cheng: "I want to confirm that when the alarm sounds, except for the lady who is with me, the alibi of everyone else ......"

"We all did what the police said, go back to our own rooms!"

A few people from Guoyou's family said angrily: "Everyone is in a single room, how can there be any alibi?" ”

"Speaking of which, you police didn't send anyone to watch at the door, did they?!"

"This ......"

Henggou can only smile bitterly.

This was indeed his negligence, but he didn't expect the situation at that time to turn into a series of killings, and it was the safest friend Chunda who died.

"Mr. Kuniyou kicked out all the police officers who were investigating on the third floor at the time, and hid in the room alone and said that no one was seen, so we had to quickly check the fingerprints of other people," Yokozo said with a worried face, "Before the results of the appraisal come out, let me reconfirm your confessions......

Gao Cheng had read the confessions of several people before, and he was not interested in continuing to ask, and after leaving Xiao Ai to watch, he and Conan and a policeman left the 3rd floor directly, and checked the rooms of the fat housekeeper and others one after another.

Judging from the killing at the pass, it was the driver Mianyin and the Guoyou couple who had an alibi.

Although the others did not have a clear alibi, the handwriting on the card found in the pocket of the pass was crooked, which did not match the obsessive-compulsive disorder of the fat butler.

Below the suspension pass is a sharp fence, and the butler Shigeko, who has a phobia of the tip, does not look like a prisoner, because it is impossible for a prisoner not to look down to check the wind, otherwise it is easy to expose herself if she is seen.

Chef Amika, who has a fear of heights and can't even get close to the window on the second floor, doesn't look like a prisoner......

Of course, the premise of these judgments is that the strangeness of several people is true.

Several illnesses can be faked, and if it is to avenge the accident 13 years ago, it is not impossible to deliberately make a false appearance.

Gao Cheng's mind flashed the figures of the fat housekeeper.

It's really powerful, generally speaking, they will find a target for planting, but the murderer specially hung the body to the balcony when he killed the pass, and ruled out everyone's suspicions.

It was already 2 o'clock in the morning, and Gao Cheng followed the police into the housekeeper Maozi's room first.

There is a potted plant on the shoe cabinet in the entrance, and a wall calendar with a date mark is fixed with duct tape on the wall, which is not supported by a pushpin or anything like that.

In addition, there was no point in the room, and even the pen was a ballpoint pen that could be retracted.

The second is the room of the housekeeper's daughter Bohua, which is quite clean and tidy, only the location of the window has obviously accumulated a lot of dust, and it should have not been cleaned for a long time.

The third is the driver's room, which is cleaner than Bohua's room.

Speaking of which, Mianyin, who has a habit of cleanliness, wears gloves almost all day long, and only takes them off when driving and writing.

Gao Cheng opened the shoe cabinet in the entrance, and the shoes inside looked like they were often cleaned, and in addition to the shoes, there was also a pair of baseball gloves on the top floor.

Before, the fat housekeeper obviously said that no one in the Guoyou family played baseball......

Gao Cheng looked at the baseball gloves for a while and continued to walk into the room.

There is a calendar hanging on the wall facing the entrance, and from a distance, you can see that the grid for each date is full of schedules, and on October 3rd, the schedule of going to Tokyo to pick up the detective is written, and each schedule has a specific time, and there is a small circle in front of it.

Gao Cheng stood quietly in front of the calendar, his eyes continuing to sweep over the schedule.

I don't know if it's accidental, there are two ways to draw the small circle, clockwise and counterclockwise, the notch is facing down and up respectively, and the difference is quite obvious if you look closely.

The two circles alternate, almost one for a day, and only the frequency of the alternation is slightly slower......

Is it possible for this Mian Yinsheng history to commit a crime?

"Joto," Conan asked, as the police officer left, "what do you see?" ”
