At noon, when Conan and Xiaolan were still watching TV and eating lunch in the social hall, a police car from the Yamagata Prefectural Police Department drove into the snow village and finally stopped in front of the Kotoya Hotel.

"Officer," Officer Shinsen's men hurried into the ballroom with a report, "something has arrived!" ”

"Is the autopsy report out?" Sitting on the sofa and communicating with Uncle Maori, he really raised his head first.

"Well, the murder weapon that killed the two victims was indeed that magic knife!"

The subordinate reported: "The blood stained on the headscarf also confirmed that it was left by Ema Anzai himself, and in addition, from the origami doll at the scene of the murder and the ancestral hall of the kimono sleeve shrine and the note received by Ema Anzai, I did not find any suspicious fingerprints or other clues related to the murderer......

Gao Cheng happened to come back from the courtyard, looked at Officer Zhenxian and Uncle Maori who were worried in the hall, and went to the open-air bathhouse with his hands in his hands.

He has almost investigated the case, whether it is the mystery of the murder of Eima Anzai or the murder of Asuka Shibasaki, he gradually has eyebrows, but the identity of the suspect is a little uncertain.

All the clues he has point to the romancer Kei Kei, whether it is the familiarity with the Kotoya Hotel or the kimono sleeve god, Kei Kei, who has been working here for a long time, meets all the conditions, including the time of the crime and the alibi.

At least from the perspective of Wise Value Wise itself, many things can be combined......

"How?" Xiao Ai walked to the leisure hall and looked at Gao Cheng, who was standing on the side of the escalator and looked at the bottom of the cliff, "Did you find the prisoner?" ”

"Still a little bit ......"

Gao Cheng's eyes swept the open-air hot springs below and the sides of the cliff slopes.

Because of the obstruction of view, you can't see the pool, only the entrance to the bathhouse at the end of the escalator.

Although it is logical that Asuka was killed after Anzai-ema, the murder weapon, the electric shock baton, and Anzai-ema's headscarf were indeed found in the bathhouse.

Eima Anzai was killed after 10:30, but no one passed through the only entrance to the bathhouse after 10:30, which was the leisure hall......

Gao Cheng looked at the hotel house on the other side of the leisure hall, there were also guest rooms and corridors on the edge of the cliff, and the windows and balconies facing the cliff could barely be seen from the side of the leisure hall.

Since there is no way for people to go down, only the items are left, and the murder weapon and the headscarf are sent to the bathhouse pool below, so that the whole case can be explained.

Gao Cheng was silent for a while, looking at the passengers who were having sporadic fun in the leisure hall, because of the fatal case, many people left the room, or just stayed in their own room, but no matter what, they will inevitably be questioned by the police, and they are in the mood to have fun enough.

"Xiao Ai," Gao Cheng suddenly asked, "What do you think of revenge?" ”

Xiao Ai raised his head: "Why did you suddenly ask this?" Is it because of this case? ”

"Although I promised Miss Harumi to investigate Suzuka Sakurako yesterday," Gao Cheng said in a deep voice, "But there are some things I didn't tell her, after all, it was five years ago, and Suzuka Sakurako still committed suicide, even if the truth is found, I'm afraid I won't be able to sentence Asuka to any crime, even if they are convicted, according to their family background, there is not much trouble...... After all, the law is dead, and it is not for nothing that the world has been acquitted of the most heinous crimes, and even the death penalty has become a death sentence with a reprieve, and in the end he has only been in prison for a few years......"

"So?"

"So to some extent, I can also understand the murderer of this murder......"

Gao Cheng traced back to a large number of cases he had handled in the past.

Since arriving in the world of Conan, in addition to daily life, it is to solve cases, solve cases, solve cases one after another, and even get used to touching corpses, so many cases do make him a little confused.

"And what are you going to do?" Xiao Wai looked at Gao Cheng lightly, "Let the murderer go?" ”

"I ......," Gao Cheng frowned.

He couldn't have ignored it, and Conan was here, so he could have found the truth without him.

"A crime is a crime, no matter what the reason...... Theories of Knights and Demons...... Seems like you're talking about that, right? Xiao Wai said softly, "Anyway, it's enough to be a detective, and you're just an ordinary person." ”

Gao Cheng smiled bitterly and looked at the preachy Xiao Ai: "You know so much...... Don't worry, I won't think too much, just for the current case, and also, the theory of knights and demons was said by the director of the Rice Art Museum Ochiai. ”

He can't guarantee that he won't harbor criminals in the future, after all, the world itself is complicated, such as the existence of Kidd the Strange Thief, but Wise Wisdom will certainly not be one of them.

……

In the open-air hot spring female bath, Officer Zhenxian led everyone to the side suspiciously, along with the confused Maori uncle.

"I said, the boy of the city, why did you suddenly call everyone here?"

"Because the mystery of the two murders has been solved."

Gao Cheng put down his mobile phone and greeted everyone, and his eyes swept over the editors of Baotian and his party one by one.

"First of all, the mystery of the secret room in the kimono sleeve shrine where Miss Eima Anzai died, and only the boots and shoe prints of Miss Ema herself were left in the snow......"

"Do you need to say that?" Uncle Maori jumped with a dark face and brows, "It's because we didn't find the murderer's footprints that it became a secret room murder, we have a headache, and we don't have time to ......make trouble with you."

"Listen to me first, uncle," Gao Cheng interrupted, "Actually, you have already noticed that those footprints of Miss Ema are a little strange, they must have been pressed from above......

"Hey, you don't mean to say that someone stepped on those footprints to go to the ancestral hall, right?"

"Of course not, in that case, you can maintain normal marks unless the shape of your feet is exactly the same, but just do it another way, just like uncle, you cover your footprints with a towel, what if the murderer uses a large wooden plank?"

Gao Cheng looked at Uncle Maori and said: "If the murderer used two wooden planks and exchanged planks on the footprints left by Miss Ema, he could try to keep the footprints as intact as possible, at the cost that the entire snow will sink, and the footprints will become shallow......

"But," asked Hantokaichi, "how did the murderer get to the back door?" Yesterday, only Ema went there alone. ”

"There's no need to go through the hall at all, just take a detour in the same way," Gao Cheng continued, "According to my investigation, the snow on the left side of the back door will be shallower than the right one, because it was also crushed by a wooden plank last night, and only in this way can it not be discovered and leave no footprints......"

"The murderer ......"

"Yes, the murderer came out of the guest room directly, and used the wooden plank along the eaves to walk to the back door first, so that the traces would not be too obvious, even if someone walked there, it would be difficult to think of the murderer's method."

Gao Cheng's gaze fell on Wise Eri, who was in the middle of the crowd.

"Mr. Eri, the trail of snow stretches all the way to the front of your room!"

"Megumi, Miss Value?" Uncle Maori's eyes widened.

"Yesterday, Mr. Eri left the open-air bathhouse and returned to her room, and then she used the method I said to go to the ancestral hall and kill Miss Ema in the name of Bando......

"That makes sense," Eri said calmly, "but what about Asuka?" How do you explain her death? I haven't been to the bathhouse since I got back to my room......"

"yes, no one goes after half past ten!"

"You don't have to go to the bathhouse at all, because Asuka Shibasaki has been killed before, and the murderer just sent the murder weapon to the bathhouse by some means after killing Eima Anzai......"

"What about origami dolls?" Uncle Maori said in a deep voice, "That doll with a kimono sleeve appeared in front of the bathhouse after half past ten, and was also sent there by the murderer?" It's impossible to do what you're talking about......"

"The paper doll was there from the beginning, to be precise, it should be hanging from the ceiling of the entrance to the bathhouse, as long as a small piece of dry ice can do it, the evidence is that the paper doll was still cold when it was found, as for the method of sending the murder weapon......

Gao Cheng raised his head and looked at the top of the cliff.

"Just demonstrate it."

The open-air bath is surrounded by changing rooms and wooden walls, and above it is a slope that connects the inn rooms to the women's bath, making it easy for those familiar with skiing to slide down without even having to control the direction.

But if you are not particularly familiar with this place, it is difficult to perceive such a special place, and the entire criminal plan is definitely not planned in a day or two, and it must have been tested and rehearsed in advance.

"I see!" On the balcony above the cliff, Officer Ogura of the Snow Village Police Station prepared two wooden planks, on which were fixed with snow a simulated murder weapon, an electric shock baton, and a prop for Anzai's painted hemp bandana.

After receiving Takasei's order, Officer Ogura immediately pushed down the plank, allowing the two planks to slide down the slope all the way over the roof of the bathhouse, and finally fell into the women's bath.

As the snow melted, several props remained at the bottom of the pool like murder weapons, and towels floated to the surface along with the wooden planks.

"This is the technique used by Eri-sensei yesterday, and the time should be around 10:50, which is when Uncle and Conan heard the sound of the female hot spring pond crackling," Gao Cheng explained, "It's just that the wooden board was replaced with a kimono belt frozen into this shape, so the long-sleeved kimono and other sashes were left on the scene as a cover......

"It does make sense," Akechi Eri's face changed, and he quickly calmed down, "but why do you think I did it?" What about the evidence? Is it because the snow in front of my room has been crushed? ”

"Miss Ema's earring pendant with one ear disappeared from the scene," Gao Cheng said to himself, "When the uncle asked you to go to the living room of the Japanese room to wait, you suggested going to the social hall, I am afraid that it was because you had to take off your shoes in the living room of the Japanese room, and the soles of your feet were still bleeding because of the stabbing wounds...... That's right, when you killed Anzai, you accidentally stepped on the earrings she dropped......"

Wise Wisdom's eyes shrank sharply.

She never thought that someone would see clearly the methods she had spent a long time planning, obviously it was just some small details, but when she arrived here, she brought out the truth of the whole incident, like a sharp sword hanging over her head.

"Y-What evidence do you have that I was stabbed in an earring?" Wise Eri's voice trembled slightly.

"I didn't look for evidence, this is already the work of the police," Gao Cheng walked out of the bathhouse with Xiao Ai with his hands, and finally looked at Wise Eri and said, "Just now, the information has been found in Tokyo, Suzuka Sakurako, who committed suicide 5 years ago, was originally named Ming Sakurako, and she had a sister before being adopted by the Suzuka family, your surname is not Wise but Ming, this is your motive for killing, right?." ”
