On the third floor of the hotel, archaeologist danze daogui's room. When the village head opens the door with a spare key, only the bald old man falls painfully by the window.

"Is there only one spare key in this room?" the service department asked the village head

"Yes, it's just me." The village head replied.

"Murder in secret room..."

The service department took a deep look at Gao Cheng who was fighting the fire downstairs.

Just now, in addition to Heye who was hiding in the room, the little half blood brother, aunt glasses and the old man all opened the window because of the sudden commotion, and the village head was with them again, that is to say, no one broke into the room.

Conan looked at the corpse and said, "the cause of death is poisoning. There are two red spots under his chin. It looks like he was bitten by a snake..."

"Hello," the Ministry of clothing also saw the wound, sweating on his face, "does that really exist? The monster called the bird... "

The tail of the bird is a poisonous snake, and the monster does show its snake like tail when it appears.

Although he didn't really believe in this kind of thing, now things are beyond his understanding.

In the end, what kind of technique can be used to be true to this point?

The fingers in the clothing department are shaking.

In any case, the layout of the prisoners will eventually affect him. It will be difficult for anyone who has seen such a giant beast with his own eyes to understand.

Now, the first puzzle has not been solved, and the second one has appeared.

Downstairs, after Gao Cheng put out the fire, he put back the fire extinguisher and carefully inspected the fire scene.

As a bystander, although many details are not clear to the parties concerned, it is relatively clear to see the problem.

It's just a simple understanding, and he has found a lot of problems.

It must not be a coincidence that the prisoner set fire to the same place twice, that is, only this place is suitable for magic.

Fixed stage, then props

Gao Cheng stands at the place where people stop when they run out of the hotel gate, and quickly analyzes the real scene in his mind.

On the right hand side is the place where there is a fire and monsters appear. People running out of the hotel are blocked by the fire and can't get close to it, and then there is a big tree next to it.

Gao Cheng looks at the tree against the wall, two or three stories high, with luxuriant branches and leaves. From his position, the hotel building is just divided into two parts.

He is not a magician, but he knows magic very well, especially the magic techniques used in cases.

This time, I'm afraid the prisoner is using "visual illusion". It's not a very clever way to jump out of the box and look at it without being influenced by preconceptions.

Because the specific requirements are too high, the more restrictive the technique is, the easier it is to be seen through.

"Sha Sha."

Gao Cheng stepped on the scorched grass and found a burnt stick near the corner of the wall, which was still wrapped with the leftover cloth. It was the residue of the first fire.

At that time, there must have been some arrangement here. There was only one chance to destroy the props. It was to demolish the props and burn them while others went back to the hotel to get the fire extinguisher and other tools.

Gao Cheng looks up.

The first floor is empty, the second floor is the glasses aunt's room, and the third floor is danze daogui's room.

Before the police came, Gao Cheng ran upstairs and walked into the scene of the murder.

Just now, he had heard that danze daogui was killed by poison, and he suspected that he was bitten to the chin by a snake.

"Chenghu," the Ministry of clothing said with a heavy look, standing beside danze daogui's body, "it seems that the matter is not simple. Two invited experts have been killed, especially Mr. danze. I can't think of how to kill him like this."

Gao Cheng squatted down to check the wound, and the court clothing department asked, "compared with this, I heard the dog barking just now. Does anyone bring the dog here?"

"You mean the dog in the restaurant," said Fu. "It was brought by the foreigner 16 years ago. According to the village head, it was originally adopted by people nearby after the accident, but anyway, it would escape here and let it stay. It seems that occasionally someone would come to feed it."

"What about the tree downstairs?" Gao Cheng continued, "the other trees in front of the hotel are pointed conifers and evergreen trees. Only this one is of different species."

Gao Cheng goes to the window and looks at the big tree that can block his sight more than pine and cypress.

No matter how dilapidated the hotel is, such trees should not be planted in front of the windows of guest rooms. The lighting of the rooms on the first and second floors must be very poor, especially the room on the second floor where the half blood brother lived, which was almost completely covered by leaves.

"We also asked the village head," the Ministry shrugged helplessly, "but he hasn't been here for a long time, so it's not clear."

Seeing that Gao Cheng was still so calm, the service department couldn't help but ask, "Hey, Chenghu, the mystery of the monster, have you got a clue?"

No, this guy didn't take part in the case. How can he feel that the investigation progress is faster than that of him and Kudo?

"I probably know who the killer is."

Gao Cheng didn't avoid saying it directly“ It's just that some places are still... " Only half of the room window is open. Gao Cheng tries to open the other side, but finds that it can't be opened at all. The left side seems to be fixed... In this way, if danze daogui leans out to look at the situation, he can only look from the right side, and the position is about one person wide. In this way, as long as danze opens a window to explore his family background, his position is fixed. If the killing method is blowing poison needles, the glasses aunt on the second floor can attack accurately, and the half open window will not block the half open window. Of course, the most suspicious is aunt glasses, because the victim's wound is under his chin. Gao Cheng himself is very suspicious of aunt glasses. The first time a monster appears, only aunt glasses can do it. However, half blood brother may not be an accomplice. It's a little strange that among the invited people, only half blood brother is unnecessary, and there is the service department. Why did the prisoner specially find a detective to come here? Originally, it was detective Maori Kogoro“ You think there's something wrong with it, too, "the service department put down his depression and analyzed it." from the position of the room, Miss Zengzi in the room directly below is the most suspicious. When Mr. danze looks out of the window to see the fire, he can directly stab it with a long stick with a poison needle installed in advance, but... "The service department shook his head and frowned," when we went to collect Miss Zengzi's mobile phone, I also checked her room and didn't find anything like a stick. "“ Do you remember what's in the room? " Gao Cheng asked“ Ah, I took a picture. " The service department took out the mobile phone with a little doubt“ There were mainly two bottles of soda water in a liter sent by the village head, then white wine, wine cups, bottle openers... The rest were ballpoint pens, adhesive tape and the like in Miss Zengzi's bag, as well as sewing bags and notebooks. The little brother's room was also photographed, including three bottles of 500ml coke, two bags of potato chips, folding knives, self timer sticks, cigarettes and lighters, It's estimated that it's a small model to kill time, and I bought glue specially. They didn't seem to have anything to use as poison weapons. At that time, the village head who was with us was just carrying a mop. Damn it, I can't understand it at all! " The service department hands Gao Cheng the mobile phone and grabs his hair anxiously“ The biggest headache is that Mr. Denzel decided to change the room by himself, or do you think the killer is really that monster? "“ Of course not. " Gao Cheng looks at the photo of his mobile phone and laughs“ It was Mr. Denzel himself who changed the room. That's right, but it wasn't entirely his own idea. The prisoner may have planned to change him to the third floor from the beginning. " He was at the scene when changing rooms. The first one who wanted to change rooms with Xiaolan was aunt glasses, and then danze found an excuse to intervene. The reason is that a notebook from 16 years ago was found in the drawer of this room. It's not normal to say that there is no plan behind this... So, if he guesses correctly, the prisoner is aunt glasses, the magic novelist, who graduated from the fine arts university and participated in the set of Zengzi Shihui. All leads to this woman.
