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 leaned together in fear.

"There are a few things I want to ask you," Mu Mu asked. "The murder happened at about 2:30 in the morning. I want to check and understand your actions one by one..."

Gao Cheng and Huiyuan stand beside Mu Mu, focusing on LAN Chuan Dongya.

This is the most popular rock singer after Daye in Jimu village. At the moment, there is nothing strange on his face.

If you insist on saying that there is something wrong, you are too calm. There is no sadness on your face. On the contrary, you are eager to get rid of the suspicion.

"So Mr. LAN Chuan appeared after Ms. Su Fang was killed?" After listening to Uncle Gao Cheng's narration, he looks at LAN Chuan Dongya.

Lanchuan didn't have a good way: "because I used to sleep well in the first floor. Later, although I heard them call Sui Naimei to get up, I don't think it would be a big deal. I didn't expect that the noise became louder and louder later. I didn't worry about it until I went to the second floor to see the situation."

Gao Cheng nodded: "that is to say, Mr. LAN Chuan didn't have an alibi at the time of the crime?"

"Well, what do you mean?" LAN Chuan frowned and said, "do you suspect that I killed the teacher? Don't they deserve to be suspected more? When I get to the third floor, the others are much slower than me! "

Mu Mu turned to the people in the west chamber and said, "is that true?"

Meinai Sui said anxiously: "I was awakened by suinai Mei with the inside line, and then I took the key to the second floor to help them open the door of the mask hall."

"I was asleep in my room at that time, but I was woken up when I heard the noise outside. When I went to the corridor to check the situation, I just saw meinaisui coming to the second floor," explained pian

"I only see when I hear the broken glass."

"Well, detective Chenghu is the first one to come to the scene, isn't he?"

"I really arrived at the door of Ms. Su Fang at the first time," Gao Cheng said calmly, facing the public's eyes, "because I always stood by the stairs."

Lanchuan Dongya's face changed slightly: "you..."

"Yes, unless the murderer is me, otherwise no one in the West Wing room can kill Ms. Su Fang," Gao Cheng said, looking at LAN Chuan Dong Ya, "Mr. LAN Chuan, did you really sleep on the first floor when the crime happened?"

"Hello," Lan Chuan said with a cold sweat, "didn't I say that? At that time, I also heard Miss LAN and this kid's voice called Sui Naimei

"Ah, yes?" Conan said strangely, "I didn't say a word at that time. How did big brother know that I followed sister LAN?"

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

"Really?" Conan raised the corner of his mouth, successfully staring at LAN Chuan and said, "that's even more strange, because at that time I was not with sister LAN at all. Although my uncle did ask me to call sister Sui Naimei with sister LAN, I ran to check the condition of the door lock!"

LAN Chuan Dongya's face suddenly changed: "how, how..."

"Yes, at that time, you were not in the room on the first floor at all. Instead, you heard uncle's words in other places, and you planned to use this as an alibi." Gao Cheng keeps a close eye on LAN Chuan.

Although Conan was very weak when he was cute, his mind was really strong enough to find a small loophole in LAN Chuan's words.

"Well, Mr. LAN Chuan, where on earth were you at that time?"

"Wait a minute," he said with a dry smile, "isn't that strange? No one in the West Wing room can kill the teacher. Can I? How could I get to the teacher's room when I was in the East Wing room? Not to mention that you are always there, the passage between the East and West Wing rooms is locked. "

"Yes," Uncle Maori nodded in a deep voice to help prove, "because I got an inside call from the self proclaimed curse masquerade Messenger, and I went to see it immediately. At that time, the masquerade hall was locked."

Mu Mu then said, "yes, brother Chenghu. At that time, both the East and West doors of the mask hall were locked. Mr. LAN Chuan was right in the East chamber when Ms. Su Fang was killed. How did he get into the west chamber before the door opened? Needless to say, I have to go around you to kill Ms. Su Fang and then go back to the East Chamber... "

Gao Cheng interrupted: "if you don't have to go to the west chamber at all?"

"Eh?" All the people in the villa were puzzled and looked at Gao Cheng.

"But only the West Wing room can enter the teacher's room..."

Gao Cheng shook his head: "even if I didn't guard the west chamber, I couldn't get into it. Besides, I didn't have to enter the dormitory to kill Ms. Su Fang."

"What did you say?"

Mu Mu was shocked and said, "didn't the killer go in?"

"Hum," said LAN Chuandong with a smile, "how can you kill people if you don't go into the dormitory? Detective Chenghu, is it because you want to get rid of yourself that you suspect me

Gao Cheng quietly looked at LAN Chuan and said, "officer Gao Mu should be ready. Now let's go to the third floor with me."

"Ready?" "What are you going to prepare?" he said On the third floor of the villa, Su Fang's dormitory next to Hongzi, which is connected with the East chamber. When they entered the room, they were surprised to see the same decoration as Su Fang's dormitory. Except for the difference in direction, it was almost the same as the scene of the crime. Gao Cheng stood by the door of the house sealed with nails and called to the opposite, "officer Gao mu, you can start."“ Yes Gao Mu's voice came from the next room, and he was puzzled. His subordinates have been abducted again... "Now I'm going to practice the murderer's crime tactics," Gao Cheng explained beside him. "First of all, after putting on the elastic band at the end of the handle, I throw it into the bedroom through the crack of the board, and then I put another elastic band through the hole in the eyes of the mask, As for the elastic band with the murder weapon, it goes through the mouth of each mask... "Songping guards are surprised to see that the fierce knife and mask connected by the elastic band are thrown into the room one after another through the cracks of the board, while lanchuan Dongya is constantly sweating. Gao Cheng glanced over LAN Chuan, who was gnashing his teeth: "the key to the mask room is in the kitchen on the first floor. People who often come here should be very clear. After everyone fell asleep, the killer took the key and stole out 200 masks in the mask room and the knife used to kill Ms. Su Fang. After locking the door, he took the key back to the kitchen, and then came to this room, After making all the preparations, I called Uncle Maori on the second floor Uncle Maori's face changed slightly: "was LAN Chuan here to kill Ms. Su Fang?"“ Shua As all the masks were put in, Gao Cheng next door strained the elastic band, and the loose masks immediately began to gather, constantly stacked together, twisted and swayed like a snake as if they were alive. Finally, they all stretched tightly above the throat of the dummy hovering on the bed. It looks like a snake monster with a dagger and a human face staring at the dummy's throat. Gao Chengping looks at the change of 200 masks. After forensics, he carefully examined the scene from beginning to end, especially the masks scattered around the corpse. The first mask was covered with blood, and the next mask had only a little blood on its mouth. In addition, because the fierce knife was bitten by the mask, the handle of the knife was also stained with blood... The thickness of the mask, the gap between the boards, the distance between the board and the corpse on the bed, the strange blood... These clues are enough for him to use the one minute mode for backward simulation. With the general direction, we soon found the traces of the murderer using the elastic band“ The distance between the lattice board and Ms. Su Fang's throat at that time was about 3.5 meters, and all the masks were stacked at least 3 meters, "Gao Cheng continued." in fact, the tip of the knife was only 10 cm away from the victim's throat. Just push the mask with a stick or something at the other end, it's enough to let the knife pierce the throat. "“ This... "Uncle Maori looked at the dagger stabbing into the dummy's throat. Facts speak louder than eloquence, and you can actually kill people outside the door... "Finally, as long as you cut the elastic band that goes through the fierce knife and the mask, the mask will be played everywhere naturally," Gao Cheng turns to LAN Chuan Dongya, "am I right, Mr. LAN Chuan?" LAN Chuan was shocked to see the masks spread out one after another, and his face turned pale: "you..." at the door of the villa, LAN Chuan was quietly taken to the police car“ However, "Xiao Lan looked at LAN Chuan's back and said," Mr. LAN Chuan is very poor. "“ Pitiful? " Gao Cheng touched his nose without making a sound. How can he feel like a bad guy? According to LAN Chuan's confession, Mr. Pian Tong's wife died in a car accident 20 years ago. At that time, it was Su Fang Hongzi, but Su Fang Hongzi put the blame on LAN Chuan's mother and killed her, creating the illusion of suicide. Even the charitable activities over the years were aimed at enriching her own pockets. Su Fang Hongzi is really mean, but homicide is not much better... "By the way," Gao Cheng looked back at the dejected Maori uncle on the other side and said strangely, "what's wrong with him? Didn't I solve a case? Not so? "“ He ah, "Conan said helplessly," it's not because of the two million bubble. "“ Two million? What two million? "
