Saturday, May 10th, afternoon, Butterfly Springs Apartment.

Mori, Yamazaki, Conan, President Hanaoka and his assistant, along with Tanaka, followed the Twilight Police Department to the door and met a courier in uniform.

The courier asked, "Your Excellency Officer, I'm just here to deliver the documents, I still have a lot of things, can you let me go?"

"What kind of document?" "The Twilight Police Department took the document handed by the subordinate and looked at it, it was a document for taking the goods, which said that one of Miss Butterfly's paintings had been taken.

The Twilight Police Department handed over the slip to Mori. Then he asked the courier, "You said you forgot to leave the slip, which means you have been here before, when did you?"

"It was more than twenty minutes ago, at 2:35 p.m. The courier thought for a moment and said, "By the way, when I went downstairs, I heard someone outside shouting, 'Someone jumped off the building.'" ”

Mori said, "Twilight Police Department, that's about the time when Miss Butterfly Wild falls. Then he stared at the courier and asked him, "Honestly, did you kill Miss Butterfly?"

"W-what!" the courier was stunned.

"You killed Miss Butterfly and pushed her down the stairs. "In terms of time, you were here, so you must have been the murderer." ”

"No...... No," the courier hurriedly argued, "I didn't see the owner of this apartment at all today, Miss Butterfly, how could I have killed her." ”

"Ha, how dare you lie to my face," Mori asked laughing, "I ask you, if you haven't seen Miss Itano, how did you get into this room, and how did you get the picture of Miss Butterfly that was written on this slip?"

"Brother Maori is right. The Dusk Police Department asked the courier, "Excuse me, how did you get in?" ”

"At that time, the door of the apartment was not closed, and I came in with a gentle push, and the painting was right at the door, so I didn't see Miss Itano. "It's strange to say, I just pushed it and the door opened, and by the way, I don't know where a nail fell from somewhere." ”

"Nails?" Mori took the nail from Conan, who came with Lan, and asked the courier, "Is it this curved nail?"

"Yes, yes. The courier said.

"Didn't you really put this on the ground?" asked Maori.

"How is it possible, I haven't even entered this threshold. The courier said, "I took the painting at the door and left, so I forgot to put down the slip that took the painting, so I came back." ”

Maori asked, "Wait a minute, you took the thing away without asking?"

"No, I've gotten a call. The courier said hurriedly.

The Twilight Police Department asked, "Did Miss Butterfly call you?"

The courier said, "No, it's Mr. Hanaoka......"

"What!" "Twilight Police and Mori were taken aback, and Mori asked, "Why is Miss Butterfly's name on this slip?" ”

"I've always been helping Miss Butterfly deliver paintings, and this time it was Mr. Hanaoka who called, but he said that he still signed Miss Butterfly's name. "He called me about fifty minutes ago, about two o'clock in the afternoon, and said that the door was open, and that I should take the painting from the door and go to the door." By the way, the time to get the painting, 2:35 p.m., was also told to me by the phone. ”

"President Hanaoka, how did you know that the painting was painted at the door, and why did the time you told the courier to pick up the painting coincide with the time when Miss Teshino fell?" Mori asked, "This is so suspicious, President Hanaoka, you did this incident, right?"

"No, no," President Hanaoka argued, "it was all told to me by Butterfly, and I just relayed her words to the courier." ”

The Twilight Police Department asked, "So, President Hanaoka, you talked to Miss Butterflyno on the phone before?"

"Yes. When I was woken up by a phone call from the studio in the studio, I received a call from Butterfly. She told me it was done, put it at the door, and asked me to call the courier company. President Hanaoka said, "I just thought there was something wrong with her tone, so I was worried about her, so I asked her to call me again." I had hoped to come back to see Mr. Maori after meeting her, but I didn't expect it to turn out like this. ”

The Twilight Police Department asked the courier, "Excuse me, what other strange situations have you encountered?"

"Well," the courier said after a moment's thought, "I seem to hear the sound of something breaking in the house, yes, like a potted plant." ”

"Bonsai?" said Mori, "I think it's the bonsai that Miss Butterfly broke when she fell." ”

The courier asked, "Well, can I go?"

"No, you were here at the time of the incident, and you were alone. "So, you're a suspect too." Then let the subordinates register the information of the courier.

Conan thought to himself, when he opened the door, a bent nail fell, and if he added a fishing line, he would hook one end to the nail, one end to hang a potted plant, and then use the fishing line to hang a heavy object and put it in the balcony drain, I see.

Thinking of this, Conan felt Ran grasping his hand tightly, and sighed in his heart, the next question is, how to get rid of Ran and Mei Daizi.

Conan thought for a moment and said to Lan: "Sister Lan, I want to ask Brother Yamazaki a question, and I promise not to run around." ”

"Okay. Lan let go of his hand.

Conan ran to Yamazaki and whispered, "I'm going to start." ”

"I see. Yamazaki smiled, "I won't ask if there's anything in the drain, you go, I'll ask my uncle to go to the balcony to find you, and I'll deal with those two people." ”

"Okay, thanks. Conan ran away.

Seeing this, Lan exclaimed, "Conan!"

"It's okay, I let him go. Yamazaki said, then stepped forward and whispered to Mori, "Conan found something in the drain pipe on the balcony. ”

Hearing this, Mori immediately went to the balcony, and then was put down by Conan, who was waiting for him.

Conan held Maori, who had fainted and fell forward, and made him fall backwards, leaning against the inner wall of the balcony, sitting on one side of the drain of the balcony, and on the other side was the fragments and dirt of potted plants, and then turned up the volume of the button speakers to the maximum, and attached it to Maori's right collar, with the right collar resting on Maori's vocal cords.

Conan tried the sound of the bow tie in a very small voice, and found that it was okay, and thought to himself, it can only be like this, this should not be said to be the back of the neck pronunciation, this is not the empty station like last time, I hope that Midaiko's troublesome guy will not hear two sound sources.

Conan stood in the bedroom and looked at it, making sure he couldn't see the sliding door on the right side of the balcony, and then shouted, "Uncle, what did you say, you said you knew the murderer's methods, I'll call the Twilight Police Department right away." ”

A moment later, the Twilight Police Department came down with a few subordinates, followed by President Hanaoka, assistants, Tanaka, Ran, Yamazaki, and Midaiko. The Twilight Police Department stood behind the balcony gate, and the police stood behind him, followed by Ran, Yamazaki, and Midaiko.

The Twilight Police Department asked Maori, "Brother Maori, do you know who the murderer is?"

"That's right," Conan said in a very small voice to the bow tie, hiding behind the sliding door on the right side of the balcony, "the murderer of this incident is President Hanaoka." ”

The Twilight Police Department asked, "Brother Maori, how did President Hanaoka come here to kill people when he was in the office?"

"As long as you have a fishing line, nails, and a bonsai, you can do it no matter where President Hanaoka is. Conan said in a very small voice to the bow tie, "By the way, the Twilight Police Department, by the way, prepare a bottle of soy sauce and a cup of hot coffee." ”

"It's okay to prepare soy sauce and hot coffee," the Twilight Police Department said, and then asked in a low voice, "But, Brother Maori, why do you even have to add soy sauce to your coffee now?"

Mei Daiko asked Ran, "Uncle, does he like to drink salty coffee?"

"I haven't seen it. Lan said.

"Well, this," Conan said helplessly into the bow tie in a very small voice, "Anyway, you'll know in a moment." ”

Under the instructions of "Maori", the Twilight Police Department hung a fishing line with bent nails on the doorbell, then took both ends of the line to the balcony and used the double strand of the fishing line to wrap twice around the railing of the balcony and a dummy in the balcony to spread the force so that the doorbell would not be able to eat the weight of the person. Then tie the end of the line to a potted plant, rotate the pot to tighten the line, place the dummy outside the railing and cover it with a quilt, continue to tighten the line so that the pot can be suspended from the balcony, and then tie it up. Then ask a police officer to go out and close the door, move the bent nail on the doorbell to hook the fishing line, and let the nail get stuck in the door.

"I see, the nails were bent so that they could be easily removed so that they would not be cut by the fishing line that fell on the human body. "And with this arrangement, whoever pushes the door open, the line will loosen, and the body under the quilt will fall." ”

Conan said in a very small voice to the bow tie, "Of course, the one who opened the door was the courier arranged by President Hanaoka in advance, and the courier came to open the door at 2:35 p.m. at the time designated by President Hanaoka, and let the dead Miss Itano fall." ”

President Hanaoka said, "Detective Maori, this technique is really interesting, but in this case, there should be fishing line in the room. ”

"It's very simple, just use a soy sauce bottle. Conan said in a very small voice to the bow tie, "Dusk Police, please pick up the lid of the drain pipe mouth, do you see the fishing line hanging from the fragments of the flower pot, pull it up." Then you'll know where the line is going. ”

The Twilight Police Department did as they were told, pulling up a bottle of contact lens and a long fishing line that was tangled together.

"I see. The Dusk Police Department said. Then, according to the instructions of "Maori", take another piece of fishing line, pass it through the lid of the drain pipe mouth, tie one end to the fishing line of the flower pot, and tie the other end to the soy sauce bottle, put the soy sauce bottle into the drain pipe, and close the lid of the drain pipe. Finally, let the police officer outside the door push the door.

The police officer outside the door gently pushed the door, the nails on the door couldn't get stuck and the door was pulled in by the fishing line, the dummies, quilts, potted plants and soy sauce bottles on the balcony began to fall down at the same time, the nails fell on the ground at the door, the dummies and quilts outside the balcony fell downstairs, the potted plants fell on the balcony and shattered, and the first fishing line tied to the bonsai at one end was dragged to the drain pipe by the second fishing line tied to the soy sauce bottle at one end with the mud and debris in the potted plant, and finally entered the lid of the drain pipe and was completely invisible.

The Twilight Police Department asked, "President Hanaoka?"

President Hanaoka said, "Who knows how there is a liquid bottle in the drain. ”

Conan said in a very small voice to the bow tie, "Dusk Police Department, please ask the forensic staff to investigate the fishing line on the contact lens preservation solution bottle, as well as the corner of the apartment, the fishing line must be stained with the decoration materials of this apartment, and there are new scratches on the corner, which should indicate that President Hanaoka has used this technique." ”

The Twilight Police Department immediately instructed the forensic officers to do this. Soon after, an forensic officer came to report and preliminarily confirmed that the killer had used the methods of the Maori detectives. At the same time, a police officer came to report and did not find Miss Butterfly's suicide note.

President Hanaoka said, "That doesn't mean anything, Detective Mori, I was obviously talking to her on the phone when Butterfly jumped off the building, and it was a call from herself, if you don't believe me, you can check the mobile phone on the balcony to see if it was on the landline of my office at that time." And Tanaka also heard the voice of Butterfly at that time. ”

"You brought this mobile phone to your office, right? President Hanaoka, you used Miss Butterfly's mobile phone to call your office's landline phone in the bathroom of your office. Conan said in a very small voice to the bow tie, "And Mr. Tanaka's voice is probably because you used a phone recording with Miss Butterfly's voice, and you put the phrase 'Hey, Izumi Butterfly', so in order for Mr. Tanaka to find out about the problem, you immediately came out of the bathroom." ”

"That's true. Tanaka said, "That's what I heard. ”

"You took the phone from Mr. Tanaka's hand, spoke loudly to divert our attention to you, and said that Miss Butterfly was going to jump off the building, so that our attention was moved to the other side, so as to create a scene of Miss Butterfly jumping down the stairs in front of everyone nearly 100 meters away. Conan said in a very small voice to the bow tie, "Later, while we were waiting for the police to come, you mixed in with the crowd of onlookers with umbrellas and took advantage of our inattention to put Miss Toshino's mobile phone and her phone call recordings back here. ”

"Where's the evidence, Detective Maori, what is the basis for what you said?" said President Hanaoka, "I haven't been here at all today, and if it's fingerprints, it's not surprising that I came here yesterday and have my fingerprints." ”

At this moment, a police officer came over with hot coffee, "Detective Maori, you want hot coffee." ”……
