"Police department," Uncle Maori shook his head, "I think it's suicide. Maybe someone changed the real one, but this is the absolute secret room at the time of the crime. It's suicide anyway."

After all, when Maori was sober, most of his judgments were wrong.

"Do you have a spare key in this room?"

"Except for my wife's own key, I'm the only one." The housekeeper responded.

"Well, the key to the room was found in the pocket of Mrs. Xuanyin's nightgown. It seems that there is no other possibility..."

"I'll tell you," said uncle Conan, who always likes to butt in with a bad look. "It's not a continuous killing at all. Mrs. Xuanyin's initials are a, it's not h at all..."

"Deng!" All of a sudden, a crisp piano sound interrupted uncle. The flowing water like brisk rhythm made the whole room feel refreshed.

Yuga Xiangfu accidentally looks at Gao Cheng who plays the piano in the room.

"Defgab," Gao Cheng stopped his fingers and the notes stopped abruptly, "the order of the letters is the scale, so G is not followed by H, but by A

"What?"

"If the murderer was a musician, surely that would be the arrangement?"

"This..." Uncle Maori said in amazement, "if the next letter is B, the person with B in his name..."

"That's Jinqu Hongsheng," the housekeeper calmly pushed her glasses. "Is that me next? When I first came here, the master did say, "if you are also our family, it's just a complete scale."

"Did I say that?" Tiao Ichiro seems to care about other things, just guarding his Stradivarius violin, coughing twice from time to time.

"In any case," murmured mu, "we need to investigate further. Please stay in your room first, with the police of course."

Gao Cheng closes the piano cover and sees tiaoyilao take the lead to leave. He calls Shele Lianxi.

"Miss Lianxi," Gao Cheng asked carefully, "why does Mrs. Xuanyin and your grandfather separate a room?"

"Because my grandfather is a heavy smoker, he didn't quit smoking until he got lung cancer. My grandmother hated the smell of smoke, so it was like this a long time ago..."

"Who will inherit Stradivarius if your grandfather dies?"

"Well, grandma and sanro are gone. Should it be me? Although grandfather said that he would take it away in his coffin... "She lelian hoped to ask Yuga Xiangfu, who was questioned by officer Mu Mu on the other side," but I think Stradivari is more suitable for uncle Xiangfu. "

"Well, I see. Thank you."

Gao Cheng takes his eyes back from Yuga Xiangfu and turns to the open window.

It's almost

After a pause, Gao Cheng goes back to the downstairs room with Conan.

"Chenghu," Conan asked as he walked, "do you find anything? The secret room... "

"First of all, we can be sure that the two incidents were both man-made. The first fire and the second jump from a building both had the situation of secret room. In addition, the connection of the past several cases, as long as we grasp these, we can definitely find the murderer..."

Gao Cheng went to the table and asked Conan, "do you remember Yuga Xiangfu's every move at that time?"

"Remember is remember," Conan doubted. "Do you doubt Mr. Xiangfu?"

"Only he is the closest to the window, and above here is Mrs. Xuanyin's room."

Gao Cheng looks expectantly at Conan.

In fact, throughout Detective Conan, most of the time Conan solved cases by virtue of his excellent talent, smart mind, active thinking, and deep knowledge, which made Conan feel like a duck in water in all kinds of cases. Therefore, he often did not have obvious reasoning methods, and did not spend a lot of energy on those reasoning methods like him.

This is the difference between genius and ordinary people. For example, he has no instant memory ability. Conan has the ability to blend into his heart. Every time he fights with this little monster, he has a lot of pressure.

However, with this guy around, it's no use

"Mr. Xiangfu came up with the violin, just at the time of twelve o'clock," Conan walked into the room from the outside, thinking back and went to the window to open the window, "and then began to play..."

"Stop!"

Gao Cheng stops Conan and goes to the window.

"Why does he have to open the window?"

"Miss Lianxi said that it was always like this when she played Requiem, because the old lady and Mr. tiaoyilang's room were upstairs, so that they could hear it too..." Conan said, holding his chin, "but I think it's too coincident. Just when he was playing, he saw the old lady jump off the building after a noise..."

"Did you hear a strange noise, too?"

"Yes, that's why we all looked out of the window..."

"At that time," Gao Cheng continued, staring out of the window, "I still remember that Miss Lianxi hid in Yuhe Xiangfu's arms and cried, and we soon left here."

Conan thought and nodded: "at that time, Mr. Xiangfu asked the housekeeper to call an ambulance, and sister Xiaolan and I followed..." "that is to say, at that time, there was only Yuhe Xiangfu and miss Lianxi who had been crying." The clues in Gao Cheng's brain seem to be gradually connected. Close your eyes and stand by the windowsill. As you enter the one minute high-speed thinking mode, all the details are presented to your mind. All the actions he saw were reproduced“ All the puzzles have been solved... "Eh?" Conan came back In the fat lady's room on the third floor, officer Mu Mu still has a headache for the case, but Uncle Maori is sure“ Police department, it must be suicide, "the uncle pointed to the door." there are only two entrances in this room, but the safekeeping room is locked from here. Only Mrs. Xuanyin and the housekeeper have the key to the door. Mrs. Xuanyin, who is in the secret room, steps on a chair, climbs up the windowsill and jumps out. What do you think is self killing... "" isn't there a third entrance? " Gao Cheng and Conan walked into the room together, "the window is always open..." "idiot!" Uncle Maori said contemptuously, "do you want to say that someone comes in and out of the window? Just now, the police department has checked it. There is no suspicious mark on it! "“ What if Mrs. yinxuanyin went out by herself? " Gao Cheng laughs. Without waiting for uncle to retort, Mu Mu said excitedly, "have you solved the mystery of the secret chamber, brother Chenghu?" Every time Gao Chengdu finds out the truth in silence, it's like riding a roller coaster when he's with Uncle Maori... "Can't you say that Mrs. Xuanyin is led down by a requiem?" Mu Mu suddenly became suspicious“ To some extent, "Gao Cheng thought of Yuga Xiangfu's figure, and his eyes soon became solid." in short, before solving the puzzle, we need to bring four suspects, and the Stradivarius, because the violin is the key to solving the case.
