In the dining room on the first floor, all the residents of the villa gathered at the dining table, with different faces, and the twin maids also leaned against each other in fear.

"There are a few things I'd like to ask you," Twilight asked, "The murder happened around 2:30 a.m., and I'd like to take stock of your actions at the time......

Gao Cheng and Gray Yuan stood beside Twilight, their attention all on Lanchuan Fuyuya.

The hottest rock singer after Tatsuya Kimura doesn't see anything unusual on his face at the moment.

If there is anything wrong with it, it is too calm, and there is no sadness on his face at all, but he looks eager to get rid of suspicion.

"So Mr. Lan Chuan only appeared after Ms. Su Fang was killed?" After listening to his uncle's narration, Gao Cheng looked at Lanchuan Dongya.

Lan Chuan said angrily: "Because I originally slept well in the room on the first floor, and then I heard the sound of them telling Suinami to get up, but I didn't think it would be a big deal, but I didn't expect it to be louder and louder later, so I didn't worry about going up to the second floor to see the situation." ”

Gao Cheng nodded: "That means that Mr. Lan Chuan did not have an alibi at the time of the crime?" ”

"Hey, what do you mean by that?" Lan Chuan frowned and said dissatisfied, "Do you suspect that I killed the teacher?" Miss Inaba, shouldn't they be more suspicious? By the time I got to the 3rd floor, the others were much slower than me! ”

Twilight turned to the people in the West Wing: "Is he telling the truth?" ”

Minaho said anxiously: "I was woken up by Honami with an inside line, so I took the key and went up to the second floor to help them open the door of the Kamen Hall." ”

Masanori Katagiri explained, "I was already asleep in my room, and I was woken up when I heard the commotion outside, and when I went to the corridor to check the situation, I happened to see Minaho coming to the second floor. ”

"I saw the glass breaking to see what was going on."

"Speaking of which, Detective Joto was the first to arrive at the scene, right?"

"I did arrive at Ms. Su Fang's door as soon as possible," Gao Cheng calmly faced everyone's eyes, "because I have been guarding the stairs." ”

Lan Chuan Dongya's face changed slightly: "You ......"

"That's right, unless the murderer is me, otherwise no one in the West Wing can kill Ms. Su Fang," Gao Cheng looked at Lan Chuan Dongya and said, "Mr. Lan Chuan, were you really sleeping on the first floor at the time of the crime?" ”

"Hey," Lan Chuan smiled in a cold sweat, "Didn't I say that?" At that time, I also heard the voices of Miss Xiaolan and this little ghost named Honami......

"Huh?" Conan said strangely, "I didn't say a word at that time, how did my eldest brother know that I was following Sister Xiaolan?" ”

"This ......," Lan Chuan said, "because I opened the door a little bit at that time and looked out, so I ......"

"Really?" The corners of Conan's mouth went up, and he stared at Lan Chuan triumphantly, "That's even more strange, because I wasn't with Sister Xiaolan at that time, although my uncle did ask me to go with Sister Xiaolan to call Sister Suinami, but I ran to check the condition of the door lock!" ”

Lan Chuan Dongya's face changed suddenly: "How, how can it be ......?"

"Yes, you weren't in the room on the first floor at that time, but you heard your uncle's words elsewhere, and you plan to use this as an alibi." Gao Cheng looked at Lan Chuan closely.

Although Conan was very poor when he pretended to be cute, his mind was really powerful enough, and even a small loophole in Lan Chuan's words could be found.

"So, Mr. Lanchuan, where were you at that time?"

"Wait," Lanchuan Fuyuya said with a dry smile and a wave of his hand, "Isn't that weird?" No one in the West Wing can kill the teacher, can I do it? How do I get to the teacher's room when I am in the East Wing? Not to mention that you have been there all the time, but the passage between the east and west wings is locked. ”

"That's right," Uncle Mori nodded in a deep voice, helping to prove it, "I immediately went to see the inside call from the self-proclaimed cursed masked messenger, and the masked hall was indeed locked at the time. ”

Twilight followed: "Yes, Brother Chenghu, the east and west doors of the Kamen Hall were locked at that time, Mr. Lan Chuan was right in the East Wing when Ms. Su Fang was killed, how on earth did he enter the West Wing before opening the door?" Not to mention, I have to bypass you and kill Ms. Su Fang before returning to the East Wing......"

Gao Cheng interrupted: "What if you don't need to go to the West Wing at all? ”

"Huh?" Everyone in the villa looked at Gao Cheng suspiciously.

"But only the west wing can enter the teacher's room......"

Gao Cheng shook his head: "Even if the West Wing is not guarded by me, you can't enter it, and you don't need to enter the bedroom to kill Ms. Su Fang." ”

"What did you say?"

Twilight was stunned, "Didn't the murderer go in?" ”

"Hmph," Lan Chuan Dongya laughed, "How can you kill someone if you don't enter the dormitory?" Detective Joto, you probably want to exonerate yourself from deliberately suspecting me, right? ”

Gao Cheng quietly glanced at Lan Chuan, and said to everyone: "Officer Takagi should be ready, now everyone will follow me to the 3rd floor to have a look." ”

"Ready?" Twilight looked dazed and said, "What are you going to prepare?" ”

……

On the third floor of the villa, there is a bedroom next door to Su Fanghongzi, which is connected to the east wing.

After everyone walked into the room, they were particularly surprised to see the exact same decoration as Su Fanghongzi's bedroom, except for the difference in direction, it was almost no different from the scene of the crime.

Gao Cheng stood by the door of the room sealed with nails and shouted to the other side, "Officer Takagi, you can start." ”

"Yes!" Takagi's voice came from next door, and Twilight was puzzled.

The subordinates were abducted again......

"Now I'm going to rehearse the murderer's modus operandi," Gao Cheng explained beside him, "First I put an elastic band on the end of the hilt and throw it through the gap in the wooden board into the bedroom, then I put another elastic band through the holes in the eyes of all the masks, and the elastic band with the murder weapon passed through the mouth of each mask......"

Matsudaira Mamoru and the others watched in amazement as the murder knives and masks connected by elastic bands were thrown into the room one after another through the gaps in the wooden planks, while Lanchuan Fuyuya continued to sweat coldly.

Gao Cheng's gaze swept over Lan Chuan, who gritted his teeth: "The key to the masquerade hall is placed in the kitchen on the first floor, and people who often come here should know very well that after everyone fell asleep, the murderer took the key and stole the two hundred masks in the masquerade hall and the murder knife used to kill Ms. Su Fang, locked the door and then took the key back to the kitchen, and then went to this room, and then called Uncle Maori on the second floor after making all the preparations." ”

Uncle Maori's expression changed slightly: "Could it be that Lan Chuan was here at that time and was preparing to kill Ms. Su Fang?!" ”

"Huh!" As all the masks were put down, Gao Cheng next door tightened the elastic band, and the loose masks suddenly began to gather, constantly stacking on top of each other, twisting and swinging like a long snake as if they had come to life, and finally all of them tightened above the throat of the dummy hovering on the bed.

It looks like a human-faced snake monster bites a dagger and stares at the dummy's throat.

Gao Cheng calmly watched the changes in the two hundred masks.

After the forensic personnel collected evidence at the scene, he carefully examined the scene from beginning to end, especially the masks scattered around the corpse by the cursed legend.

The mask that hit the head was covered in blood, and the mask that followed only had a little blood on the side of its mouth.

In addition, because the murder knife was bitten by a mask, the handle of the knife was also stained with blood......

The thickness of the mask, the gap between the planks, the distance from the planks to the corpse on the bed, the strange bloodstains...... These clues were enough for him to run a backward simulation using the one-minute mode.

Once you have a general direction, you can quickly find traces of the murderer's use of elastic bands.

"The lattice plank was about 3.5 meters away from Ms. Su Fang's throat at the time, and all the masks were stacked on top of each other at least 3 meters," Gao Cheng continued, "In fact, the tip of the murder knife was only 10 centimeters away from the victim's throat, and just pushing the mask with a wooden stick or something like the other end was enough for the murder knife to pierce the throat." ”

"This ......," Uncle Maori glared as he stabbed the dagger into the dummy's throat.

Facts speak louder than words, and you can really kill people outside the door......

"In the end, as long as you cut the elastic band that passed through the murder knife and the mask tightly, the mask will naturally be bounced everywhere," Gao Cheng turned to Lanchuan Fuyuya, "Am I right, Lanchuan-san?" ”

Lan Chuan watched in horror as the masks were scattered one after another, and his face turned pale: "You ......"

……

At the door of the villa, Lan Chuan was silently taken into the police car.

"However," Xiaolan looked at Lan Chuan's back and couldn't help but speak, "Mr. Lan Chuan is actually quite pitiful. ”

"Pathetic?"

Gao Cheng touched his nose and didn't make a sound.

How can it feel like he's the big badass?

According to Lan Chuan's confession, Mr. Katagiri's wife died in a car accident 20 years ago, and the perpetrator at that time was actually Su Fanghongzi, but Su Fanghongzi put the blame on Lan Chuan's mother, and killed Lan Chuan's mother to create the illusion of suicide.

Su Fanghongzi is indeed very despicable, but the crime of murder is not much better......

"By the way," Gao Cheng came back to his senses, looked at the dejected Maori uncle on the other side, and said strangely, "What's wrong with him?" Didn't I solve a case? Isn't that the case? ”

"He," Conan said helplessly, "it's not because 2 million is in the soup." ”

"2 million? What 2 million? ”
