On the third floor of the hotel, archaeologist Dan Ze Daogui's room, waited until the village chief opened the door with a spare key, and only the bald old man collapsed by the window with a painful face.

Hattori asked the village chief, "Is there only one spare key for this room?" ”

"yes, just on me." The village chief replied.

"Murder ...... in a Closed Room"

Hattori looked at Gao Cheng, who was fighting the fire downstairs, in a deep voice.

Just now, except for the few He Ye who were hiding in the room, the half-race brother, the glasses aunt, and the old man all opened the windows because of the sudden commotion, and the village chief was with them again, which means that no one broke into this room.

Conan looked at the body and said, "The cause of death is poisoning, there are two red spots under the chin, which look like marks from a snake bite......"

"Hey," Hattori said as he saw the wound and sweated on his face, "does that really exist?" The monster called the Ostrich ......"

The bird's tail was a poisonous snake, and the monster did show its snake-like tail when it appeared.

Although he didn't believe in this kind of thing, it was a little beyond his comprehension now.

What kind of techniques do you need to use to get to this point?

Hattori's fingers trembled.

Regardless, the layout of the prisoner still affected him after all, and anyone who had seen that kind of behemoth with their own eyes would find it difficult to understand.

And now, the previous puzzle has not been solved, and the second one has appeared.

Downstairs in the hotel, after Gao Cheng extinguished the fire, he put the fire extinguisher back and carefully checked the fire scene.

As a bystander, although many details are not clear to the parties, they are relatively clear about the problem.

Just after a brief understanding, he found a lot of problems.

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

A fixed stage, and then there are the props......

Gao Cheng stood where everyone stayed when they ran out of the hotel gate before, and quickly analyzed the real scene in his mind.

On the right-hand side is where the fire and monsters appeared, and the people who ran out of the hotel were blocked by the fire and could not get closer, and then there was a big tree next to it.

Gao Cheng looked at the tree against the wall, two or three stories high, with lush foliage, and from his position, it happened to divide the hotel building into two parts.

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

This time, the prisoner may be using "optical illusions", but if you jump out and look at it without preconceptions, it is not a particularly clever technique.

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

"Rustle."

Gao Cheng stepped on the charred grass and found a burnt stick near the corner of the wall, which was still wrapped with the leftover cloth from the burn, the remnants of the first fire.

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

Gao Cheng raised his head.

There is no one on the first floor, the second floor is the room of the glasses aunt, and the third floor is the room of Danzawa Daogui.

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

Just now, he had heard the news that Dan Ze Daogui had died of poison, and he was suspected of being bitten by a snake to the chin.

"Joto," Hattori said with a heavy expression as he stood beside Michiki Tanzawa's corpse, "It seems that things are not simple, two experts who have been invited have been killed, especially Mr. Tanzawa, I can't think of how to kill him like this." ”

Gao Cheng squatted down to examine the wound and asked Hattori, "Compared to this, I heard a dog barking just now, did anyone bring a dog over?" ”

"You mean the dog in the restaurant," Hattori said, "it was the dog brought by the foreigner 16 years ago, and I heard from the village chief that it was originally adopted by someone nearby after the accident, but it would have escaped here anyway, so it was left behind, and it seemed that someone occasionally came to feed it." ”

"Where's the tree downstairs?" Gao Cheng continued to ask, "The other trees in front of the hotel are all spiky pine and cypress evergreens, only this one in front of it is of a different species. ”

Gao Cheng walked to the window and looked at the big tree, which was obviously more obscured than the pine and cypress.

No matter how dilapidated the hotel is, this kind of big tree should not be planted in front of the guest room window, the rooms on the first and second floors must be very poorly lit, especially the room on the second floor where the mixed-race brother lived, which was almost completely obscured by leaves.

"We've asked the village chief too," Hattori shrugged helplessly, "but he hasn't been here for a long time, so I don't know." ”

Seeing that Gao Cheng was still so calm, Hattori couldn't help but ask, "Hey, Joto, the mystery of the monster, do you already have a clue?" ”

No, this guy obviously didn't have much involvement in the case, so how do you feel that the investigation is progressing faster than him and Kudo?

"I kind of know who the killer is."

Gao Cheng did not shy away from saying directly.

"It's just that there are still some places...... Hey? ”

The window in the room was only half open, and Gao Cheng tried to push the other side open, but found that it couldn't be opened at all.

The left side seems to be immobilized......

In this way, if Danze Daogui leans out to check the situation, he can only look at the right half, and the position is about one person wide, so as long as Danze leans out of the window, the position is fixed.

If the murder method is blowing a poison needle or something, the glasses aunt on the second floor can attack accurately, and at the same time, the half-breed brother in the third room on the third floor can also attack, and it will not be blocked by the half-open window.

The most suspicious is of course the aunt with glasses, because the victim's wound is under the chin.

The high-cost body is also very suspicious of the glasses aunt.

The technique used when the first yokai appeared can only be achieved by Aunt Glasses.

However, the mixed-race brother may not be an accomplice.

It's a little strange.,Among the people invited.,Only the mixed-race brother is not necessary.,And Hattori.,Why did the prisoner have to find a detective to come over.,The original one who was invited was Detective Kogoro Mori.。

"You also think there is a problem," Hattori put down his depression and analyzed, "Judging from the location of the room, Miss Masuko in the room directly below is the most suspicious, and it is completely possible to stab Mr. Tanzawa directly with a long stick with a poison needle in advance when he leans out of the window to see the fire, but it is ......"

Hattori shook his head and frowned, "When we went to collect Miss Masuko's phone, we also checked her room and didn't find anything like a long stick. ”

"What are the items in the room, do you remember?" Gao Cheng asked.

"Ah, I did take a picture."

Hattori took out his phone with a hint of confusion.

"The main thing in it is two one-liter bottles of soda sent by the village chief, then white wine, wine glasses, and corkscrews...... The rest is the ballpoint pen in Miss Masuko's bag, tape paper, etc., as well as a sewing kit and a notebook.

The little brother's room was also photographed, three bottles of 500 ml of Coke, two bags of potato chips, folding knives, selfie sticks, cigarettes and lighters, a small model estimated to pass the time, and specially bought glue,

Neither of them seemed to have any weapons that could be used as poison, and the village chief who was with us at the time was just carrying a mop, damn it, I couldn't figure it out at all! ”

Hattori handed the phone to Gao Cheng and grabbed his hair in annoyance.

"The most troublesome thing is, did Mr. Tanzawa decide to change the room by himself, or do you think the murderer is really that monster?"

"Of course not."

Gao Cheng looked at the photo on his phone and chuckled.

"It's Mr. Tanzer himself who changed the room, yes, but it wasn't entirely his own idea, the prisoner probably planned to let him move here on the third floor from the beginning."

He was on the scene when he exchanged rooms, and the first one who rushed to change rooms with Xiaolan was Aunt Glasses, and then Dan Ze made an excuse to intervene.

The reason for this was that a 16-year-old notebook was found in a drawer in this room.

Behind this, it would be normal to say that there is no planning......

So, if he didn't guess wrong, the prisoner was Aunt Glasses, the magic writer, who graduated from the University of Fine Arts and intervened in the set of Masuko Shihua.

All the clues point to this woman.
