Sunday, August 11th, afternoon, Lucky Cafe.

In the row of booths next to the aisle where you can go to the bathroom, you sit down from the outside to the inside, a beautiful brunette girl, Conan, and a young man with long hair. Conan suspects that the long-haired man is Ran's date, and immediately shifts from the seat leaning on the brown-haired beauty to the seat leaning on the long-haired man's seat.

At this moment, the long-haired man's mobile phone rang. The college student passed by Conan and went to the bathroom.

"Hey, I'm Prince Ruo. …… What, good man, it's you. …… I made an appointment with the girl to meet, don't be mischievous...... That's right, it's the same woman, the cute-looking girl I met during my internship at the TV station. ”

At this time, the college student returned, and the brunette beauty passed by Conan and went to the bathroom.

"TV station?" Conan muttered to himself, "when the producer was killed last night? Wasn't Lan with Yamazaki and Midako? ”

"There aren't many naïve girls anymore," said Mr. Ruo Prince, smirking, "a woman is an animal, as long as you say a few kind words to her, you will be able to catch it." He burst out laughing.

Conan said angrily, "This guy ......"

"By the way, don't say it to other girls," Mr. Waka said with a smile, "hang up." ”

At this moment, the brown-haired beauty returned, and Mr. Yoyama, who was sitting at the bar, passed by Conan and went to the bathroom.

"Okay, look at me, when I get my shoes stronger, I'll kick you playboy out. Conan crouched down as he spoke, trying to turn the knobs on his shoes to the maximum.

At this time, the phone in the café rang, and the waiter answered the phone and shouted, "Mr. Edogawa, is there a Mr. Edogawa here?"

"Uh," after a pause, Conan stepped forward and said, "I am." ”

The waiter smiled, "Your phone, little brother." As he spoke, he handed the phone to Conan.

Picking up the phone, Conan smiled and said, "Thank you, big sister." ”

Conan asked, "Hey, who?"

Lan shouted, "Conan!"

Conan asked again, "Sister Xiaolan?"

Lan said: "I'm sorry, I can't go back to you now, the cash register in this store is broken, and there is no way to get change." ”

At the same time, Mei Daizi's voice came from the phone, "I just saw that the drawer of the cash register couldn't open and patted it," and then it should have eaten a bite of cake, "Isn't the drawer open now?" and then it should be the boss's voice, "However, the cash register doesn't seem to show up now." ”

Twitching the corners of his mouth, Conan smiled and asked, "Sister Lan, why is Sister Mei Daizi also there?" At the same time, he thought to himself, the cash register must be broken for a while.

"Yamazaki and Midaiko met on the road, and this was called from Yamazaki's mobile phone. Lan said, and then asked, "Did anyone come there to look for me just now?"

Looking at Mr. Ruo's long hair, Conan said angrily, "Yes, the hair is long, right?"

"Yes, this is the person. Lan smiled, and then asked suspiciously, "But it's really strange, I usually tie my hair up." ”

Seeing that Mr. Waka Prince was tying up his hair, Conan said again, "That's right, it's tied up now." ”

At this time, Mei Daizi's voice came from the phone again, "Okay, no, it's too slow, I'll just compensate you." How much does this cash register cost, is this enough enough? ”

At this time, Mr. Dianshan returned, and Mr. Wakaoji got up and went to the bathroom.

"No, Sister Lan," Conan said again, "don't meet with this kind of person, okay?"

At this time, the boss's voice came from the phone again, "This kind of high-end cake is sent by the head office, and we can't make it without the ingredients." Then came Missako's voice, "How long will it take, more than an hour? I can't wait that long." It's really ......" followed by the sound of the cash register being slapped again. Then it was Midaiko's voice again, "yes, come on, boss." Don't worry, if you say you will lose it, you will definitely lose it, and you hurry up and get change. ”

Lan smiled: "The cash register seems to be good, I'll go back immediately." With that, he hung up the phone.

Hanging up the phone, Conan said, "Damn, that hairy guy, I'll just wait he comes out of the bathroom..."

At this moment, Mr. Wakaoji's screams came from inside the bathroom.

Conan immediately rushed into the bathroom, and when he saw Prince Waka, who was sitting on the ground with trembling legs, he asked, "What happened?" At the same time, Conan looked around because he smelled blood.

Prince Ruo said in fear: "Blood ......"

There were two single rooms in the bathroom, and Conan was taken aback by looking at the red liquid flowing from the single room inside on the ground, it was ...... Thinking about it, I rushed over. Pushed the door of the private room, it seemed to be blocked by something, Conan immediately spun his shoes, jumped on the door, and looked inside, the woman in yellow was covered in blood and fell on the side of the door, the murder weapon knife was next to it, the leather bag was turned over, and things were spilled on the ground.

Soon after, the Twilight Police Department arrives with their men and cordons off the coffee shop. After taking the photographs, the examiners removed the body and sealed the contents on the ground in a bag.

After looking at the ID card, the Twilight Police Department said, "Yayoi Himeno is twenty-four years old this year. Then he took the photo he had just taken and asked Conan, "So just like the one in this photo, the victim fell against the door, isn't it, Conan?"

"Because I found the door was unlocked, I jumped up to it," Conan said. ”

The Dusk Police Department asked, "What is the cause of death?"

"He was stabbed in the heart and killed," the forensic officer said, "but there seemed to be some strangulation marks on the victim's neck." ”

"Well, she doesn't seem to have struggled, the killer first strangled the victim's neck to make her unconscious, and then stabbed her in the heart with a knife, the victim lost a lot of blood and died after the knife was pulled out. "He must have wanted to steal the victim's money, but he was seen with the intention of killing." Looking out of the open window of the room, which was a fire alley where no one had passed, he dropped the murder weapon, the victim's bag, and the emptied purse, and then blocked the door of the bathroom with the victim's body. In other words, this murderer who invaded through the window had been waiting for his prey there for a long time, and after killing Miss Himeno who happened to come in, he robbed her money and fled through the window in a panic, which must have been done by someone from the outside. Then he commanded, "Go around at once and ask about the situation." ”

Conan said, "Wait a minute, Dusk Police, look at that window, isn't it too clean?"

The Twilight Police Department laughed, "That's good, the bathroom is supposed to be clean." ”

"I didn't mean that," said Conan, "that the victim had so much blood, and the murderer must have had blood on his body." ”

"By the way, if that's the case, there should be traces on the window where the murderer fled. "However, maybe the killer wiped it clean, and there is water to wash away the blood stains and paper to wipe it off." ”

"But, Dusk Police, didn't you say that the murderer fled in a panic?" Conan asked rhetorically, "How could a murderer who left a murder weapon at the scene of a crime do this?"

"In that case, judging from the fact that the murderer left the murder weapon here and didn't take it with him," said the Dusk Police Department in surprise, "Could this be an internal criminal?"

Conan laughed, "It must be." At the same time, I thought to myself, I'm so tired.

"However, the door of this private room was blocked by the victim's body at that time, and there was no trace of the body moving, and the private room next door had no window, so you can't go out from this side and then come in from the next door," said the Twilight Police Department, "How is the murderer going to get out of the private room?"

Pointing to the space between the door and the ceiling of the private room, Conan said, "Of course, there is only one way, ...... from above."

"That gap ......" The Twilight Police Department looked at their men, then pointed to a police officer who had just entered, "Inspector Takagi, please try it." ”

"Inspector Takagi?" Conan looked up, and sure enough, it was Inspector Takagi he knew, and he was still wearing the uniform of Rice Flower Town, and it seemed that he had been transferred to help.

Seeing that Takagi Patrol easily crawled over, the Dusk Police Department said: "But if the murderer is stained with blood, there will be blood on the wall when he climbs, by the way, there is water and paper here, he can wipe off all the blood stains while climbing, but isn't he afraid that someone will suddenly break in and see it?"

Conan pointed to the door of the bathroom and said, "Dusk Police, you see, there is a lock on the door at the entrance to this bathroom, as long as the door is locked, this is a secret room." ”

"Well," the Twilight Police Department ordered, "immediately identify the person who went into the toilet before and after the victim." ”

"I know who they are," Conan said, "because I happened to see them. ”

The Twilight Police Department asked, "Conan, are you serious?"

"Well," said Conan, "in order, a college brother, a brown-haired aunt, a big uncle, and finally the long-haired and pigtailed brother." ”

The Twilight Police Department ordered, "Inspector Takagi, please go and invite them in." ”

Takagi opened the door to the bathroom, and the brown-haired woman came in first, "Little brother, it turns out that you are that Conan, and you are indeed very smart, but this is the end of the detective game." ”

Conan was taken aback, she knew me?

"...... you," the Dusk Police Department asked in surprise, "why are you here?"

"I'm here because I made an appointment with a friend to meet here and do something. The brown-haired woman replied, and continued, "Dusk Police, I heard what you said to Conan. After all these years, the Dusk Police Department, I now understand how the two of you solved the incident. It turned out that they were all relied on, and I really obeyed you. ”

The Twilight Police Department asked angrily, "How can this be said to be Meng?"

The brown-haired woman asked, "Then let me ask you, is the victim's clothes neat?"

"Uh......" The Twilight Police Department froze.

The brown-haired woman said: "The person standing outside the window wants to make the victim inside silent, in Le's words, it is only when the victim sits on the toilet to make a move, and at other times, it is impossible for the person standing outside the window to strangle the victim silently." Then he said, "All right, you turn around and I'll check it out." ”

After a moment, the brown-haired woman said, "Okay, you can turn around." And then he said, "The clothes are good." ”

Looking at the three people brought in by Takagi's patrol, college students, big men and long-headed men, Conan said: "In other words, the murderer is someone the victim knows, so the victim didn't call for help at the first time......?"

"Or maybe the four of us waiting at the door, suddenly attacking her when she came out. Looking at Conan, the brunette said, "Do you want to say that, Conan?"

"Uh......" Conan was stunned, why did he shiver all over his body as soon as he was stared at by her?

The Twilight Police Department laughed, "How could it be you?" and then asked the three of them, "Can you please introduce yourself?"

The brown-haired woman said, "It's too early to say who it is." As he spoke, he took the photos of the scene from the hands of the Twilight Police Department and compared them to the scene.

The college student smiled: "My name is Huang Yuyi, I am twenty-five years old this year, and I came here today to write my thesis." ”

Mr. Toriyama said, "My name is Toyayama Thirteen, and I come to this shop every day, and I like to talk to the owner. ”

Mr. Wakaoji said, "My name is Wakaoji Juro, and I'm here to wait for a girl. ”

Wait a minute, Conan thought to himself, what, what's different from the previous one.

The Twilight Police Department asked, "Do any of you know the victim?"

The three of them hurriedly shook their heads together and said no.

The brown-haired woman said, "Dusk Police, I should ask the owner and waiter of this shop this question." ”

The Twilight Police Department immediately ordered Takagi to patrol and invite them over.

After a while, the boss and the waiter came over, knowing the problem, and they both said that today was the first time they had seen the victim.

Then. The brown-haired woman said: "It seems that the murderer made the victim lie down on his side and pulled out the murder weapon after blocking the door, so there was no blood around it, only the lower end of the toilet was splashed." ”

What a great observation, Conan thought in surprise.

The Twilight Police Department asked in surprise, "So, there is no blood on the murderer, so he escaped through the window?"

"There may be some on the arms, pay attention to some that should be able to go out without leaving a trail of blood. The brown-haired woman said, then to the Twilight Police Department, "Please have the forensic personnel check the toilet seat for footprints, whether it is through the window or through the crack in the door, this place of foot is a must." The marks on it, whether from the outside of the window or lying on the door, are not easy to erase. And if there are traces of friction on the wall, if you want to climb out without stepping on the wall, few people can do it. ”

Conan asked, "What if you don't have shoes on, throw them out first?"

Glancing at Conan, the brown-haired woman said, "If the murderer is so careful, then there is something wrong with this murder weapon." As he spoke, he took the bag containing the murder weapon from the forensic officer.

The Twilight Police Department asked, "What's wrong with the murder weapon?"

Conan said: "If the murderer had been careful, he would have taken the murder weapon away and left it at the scene, which means that he had to leave the murder weapon at the scene." Then he asked, "Auntie, is that so?"

"Hmm. Nodding, the brown-haired woman said, "Conan is right. ”……
