Chi Fei arrived late at the entrance outside and opened the shoe cabinet.
What he found strange was how clean the place was.
The chair on Sachiko Nishimura's side still showed signs of being pulled up and stood up, but there were no signs of it on the other side's side. In other words, the other side restored the chair after committing the crime.
And there are no traces of his time on the ground or on the chairs...
Only those who have received professional training, wearing gloves and hats, and cleaning up the scene afterwards can leave no personal traces at all and be able to compete with the organized home invasion and search operations.
Moreover, this person also has obsessive-compulsive disorder and must pull up his chair.
It's just that her boyfriend came here for a date dressed like this and didn't touch any food. Doesn't Sachiko Nishimura find it strange?
There were no signs of struggle at the scene, indicating that Sachiko Nishimura had no defense at all.
It is not ruled out that Nishimura Sachiko knew that her boyfriend was engaged in a special job, or that the boyfriend pretended that he had an illness and could not have a hair dryer.
But there are no traces of wiping...
Even if the other party wears gloves, as long as the gloves touch the surface of those things, the fingerprints left by Sachiko Nishimura may be wiped off, leaving traces of wiping. There is not even a trace of wiping, which he cannot do.
In this world, there was probably only a soul like Xiaomei who could "pick up something and hit someone to death without leaving any traces of contact." It was because of this that he suspected that Nishimura Sachiko's boyfriend did not exist at all.
This is also easy to verify, just look at the shoe cabinet.
In Japan, it is customary to change into slippers when a guest enters the house. Unless you force your way in, you will change your shoes.
The shoe cabinet at the entrance often hides many clues.
Haiyuan Ai followed Chi Fei to the entrance late and watched Chi Fei Chi open the shoe cabinet. After seeing the situation in the shoe cabinet, he couldn't help but froze for a moment. He knelt down and watched Chi Fei Chi put on gloves and check the slippers one by one. .
The slippers in the shoe cabinet are all of the same style, with a complete range of sizes and sizes. There are small sizes for children, medium sizes for women, and larger slippers for male guests or For female customers with larger feet, there is more than one pair of each size.
This is very common in Japan. Because disposable slippers are uncomfortable, providing them to guests would seem careless, and throwing them away after wearing them once is too luxurious. Therefore, many slippers are prepared at home. The styles are unisex, and because slippers are larger, they are smaller. It doesn't matter at all, just prepare slippers that can be worn by ordinary children, men, and women.
Due to the materials used for slippers, the areas where the shoes contact the soles of the feet will dent after being used for a long time. However, there are only two pairs of slippers in the shoe cabinet that show signs of regular use and cleaning, and the others are very new.
Chi Feichi put on gloves and took out all the slippers and looked at them. "There are no signs of use on the men's slippers, not even one pair, and the same goes for the children's slippers. There are three pairs of women's slippers that are used frequently, and two pairs of them are used the most." , the other pair is less, but it seems that all three pairs have been used for more than two months.”
"Is it the same as you, who cleans up all the slippers and throws them out every once in a while?" Haihara Ai guessed, "It's just that she only cleans the slippers used by guests, and keeps the slippers that she usually wears and has already worn. accustomed."
She suspected that Chi Feichi had obsessive-compulsive disorder.
The house is always cleaned, even the gaps must be cleaned thoroughly. The garbage bags in the trash can are never full. When I have time, I pack them up and go downstairs to throw them away. Even my slippers have to be completely changed every once in a while. Including the slippers Chi Feichi wears himself, he often replaces them with new ones.
The slippers she was wearing the day she was just picked up by Chi Fei Chi had already been thrown away by Chi Fei Chi. After that, every once in a while, she would find that the slippers she wore that looked good last time were gone and replaced by a shoe cabinet. new.
Although the styles are the same, there's nothing wrong with wearing new ones, but it still feels strange every time I can't find the slippers I wore last time.
Especially the slippers she wore for the first time when she went to Chi Feichi's house. Such commemorative slippers were actually lost by Chi Feichi long ago, which made her somewhat depressed...
Wait, Brother Fei Chi isn't trying to prevent someone from guessing the number of visitors to his home from the frequency of slippers being used, right?
But that’s not right either.
Who would secretly go to Chi Feichi's house to look at slippers?
Even if someone is secretly investigating Chi Feichi, they go there openly every time. If they want to know about the visitors and living habits of Chi Feichi's home, they just need to stay and monitor for a period of time, or ask people in nearby stores, which is better than sneaking into that place. In an apartment building with strict security, it is much more convenient and simpler to go into Chi Feichi's home and check the shoe cabinet.
Anyway, Brother Chi either has obsessive-compulsive disorder and doesn't like to see slippers that have been used for too long, or he has persecution delusions and always suspects that someone is trying to harm him...
Chi Feichi didn't know that Haiyuan Ai's thoughts were wandering so far, so he took out a pair of regular slippers and a pair of large slippers with no signs of use, and turned them to the side so that Haiyuan Ai could see the less conspicuous alphanumeric combination on the side of the slippers' soles. , "Except for children's slippers, the first four digits of the adult slippers are the same as the factory item number."
In Japan, 'hospitality slippers bags' are sold in packages, which are available in large, medium, and small sizes of the same style, so that customers do not have to waste time selecting and choosing slippers when buying hospitable slippers.
Most of these 'slippers bags' are already packed when they leave the factory. Except for children, the product numbers will be different, and adult slippers will be packaged in the order of shipment.
Due to the different code sizes, the numbers of slippers of different sizes cannot be arranged completely in order, but the six-digit item number in English and the first four digits are exactly the same, which also means that it is the same batch of goods, and it is very likely that they are the same 'Slipper bag'.
"Brother Chi, Haiyuan, what are you doing here?" Conan also found the entrance and saw Chi Feichi squatting in front of the shoe cabinet and Haiyuan Ai looking on. He peeked into the shoe cabinet and was stunned. For a moment, "These slippers..."
"Even if the same batch of slippers with the same item number are not purchased on the same day, the purchase time interval will not be much different," Haibara Ai helped explain the situation, "But the women's slippers have been used frequently for more than two months, and the larger men's slippers There are no traces of use like children's slippers, that's what Brother Fei Chi said after observing them."
Conan frowned and saw the gloves on Haiyuan Ai's hand. He reached out decisively and said, "Haiyuan, give me the gloves."
The detective put on his gloves and turned over the slippers again to confirm that Chi Feichi's judgment was correct.
"If the murderer didn't take away the slippers he used after committing the crime, it means that there have been no male visitors here in three months." Conan stood up after checking, looked at the location of the restaurant, and said the result seriously, "Although There is no pattern in the slippers and the last two item numbers. It is impossible to tell whether any slippers were discarded. However, considering that her boyfriend left no traces at all, not even wiping fingerprints, it is possible that it is what Miss Nishimura said. Boyfriends do not exist at all. For the sake of safety, some women who live alone will indeed create the illusion that there are men living with them at home, or that there are men at home who visit frequently..."
"But is it necessary to buy such expensive beef and red wine to create an illusion?" Haihara Ai asked, "And she seemed really looking forward to it last night and very happy."
Conan was silent, frowning in thought.
That's right, if it's to create an illusion, there's no need to spend so much money...
Chi Feichi thought about it and couldn't remember what happened this time. It was probably not a complicated case, but he seemed to have seen this kind of behavior somewhere...
"Miss you."
"Miss you?" Conan looked up at Chi Feichi, vaguely feeling the clue.
"The owner of the butcher shop yesterday said that the 25th of every month seems to be the day when Miss Nishimura meets her boyfriend," Chi Feichi said. "It may be that the boyfriend who has broken up has mentioned the special day, or has On an anniversary of my deceased boyfriend, I once met a woman who always said she had a boyfriend. She would hold a birthday party for her boyfriend every year, but her boyfriend actually died several years ago. .”
"In this case, that person left no trace but Miss Nishimura was indeed happy and looking forward to it, which can explain that it was a boyfriend who once existed but no longer exists, and she is still deceiving herself. Everyone A well-prepared date was created on the 25th of the month, and the photos on the table were probably left by that man before," Haihara Ai took over, "If that's the case, I hope that man is dead. Instead of leaving her behind."
Conan's half-moon eyes said, "Hey...if you leave, you still have a chance to get back together, but if you die, there is really no hope. Anyway, it's better to leave, right?"
Hui Yuarai nodded indifferently, "That's right, then just treat it as if I didn't think it through well, and then add one more thing, if there is no possibility of that man coming back, then it would be better to die."
Conan: "..."
"Takagi!" Chiba Kazun walked in quickly and walked towards the restaurant, "I have confirmed this with her friends. She and this boyfriend seem to have started dating half a year ago, but her boyfriend may be too I'm busy, and it seems that I can only come here to see Miss Nishimura on the 25th of every month, so from the first to the 25th of every month, Miss Nishimura will look very happy from early in the morning, but what is her boyfriend like and what kind of person is he? Her colleagues don’t know her last name.”
"So, there are absolutely zero clues." Takagi Wataru had a headache.
Chiba Kazuno continued, "I asked a nearby lady who was a good friend with her when she was in school, but I didn't get any clues. Even the lady she had made friends with recently, she didn't know. …”
"Then do you want to ask again?" Conan followed to the door of the restaurant, pretending to have an innocent expression and a cute childish voice, "Go and ask Miss Nishimura if she had a boyfriend before!"
"Previous boyfriend?" Takagi Wataru was confused.
"because……"
Conan turned around and found that Chi Feichi and Haiyuan Ai had already gone outside to wait. He could only take over the explanation work alone, "Brother Chi found that none of the men's slippers in this family have any traces of use..."
After listening to Conan's explanation, Takagi Wataru asked the other police officers who searched the house to put the slippers into evidence bags, and then he and Chiba Kazunobu led a group of people to Nishimura Sachiko's good friend's house to inquire about the situation.
