"It's true, that's right," said Dingwu, with a light beard, in the temporary interrogation room. "There's a reason why I want you to stay, of course, because I don't want the ghost of the watchmaker to be treated as a prisoner, my partner who has been playing together since childhood."

"Well," murmured Mu Mu, looking at the light side of his hands, "your hands and cuffs are stained with blood..."

"Well, I got it when I got to the fallen lady," he explained, spreading his hand. "Besides, I didn't get blood anywhere else, did I?"

"That's right, but... Did you notice anything at the time of the crime?" Mu Mu continues to ask a way.

"In this way," he thought softly, touching his chin and moustache, "it seems that he heard the sound of cloth rubbing. The prisoner may be a woman in a dress, but I don't know if she is carrying a long, sharp weapon or something..."

"Can we have a look at your pipe?"

"Of course."

Gao Cheng has been looking at Mu Mu's interrogation one by one, recording the information of the most suspected beards in his notebook.

Qingbian Dingwu, a 45 year old man with a beard, is an architect who designed a luxury home for Baoke family. He is also a childhood playmate of a dead watchmaker.

Zhou fangzhiqiu, 39, is a female guest who flatters Mrs. Baoke. She is the interior designer in charge of the interior decoration of Baoke's home and the younger sister of the watchmaker.

Gu yuanlunzuo, a 64 year old man with a bald head and white beard, is a watchmaker who made clocks as big as a clock tower. Since the watchmaker died four years ago, he has come to check the clocks every year and is an old friend of the watchmaker.

Interestingly, almost all of the three people have relations with the watchmaker who died four years ago.

"After stabbing my wife, the prisoner ran away from my left side very quickly," said Zhou fangzhiqiu, the female designer, revealing her left arm. "So you see, my left arm is stained with the blood that I wiped at that time, right?"

"By the way," Takagi said, turning to the hair of the female designer after checking the bloodstain, "is that hairpin in your hair?"

"It's the hairpin my brother bought for me before!" The female designer angrily took out the hairpin and handed it to Gao mu, "if you doubt me, if you want to check, just check it, but remember to give it back to me later!"

After the investigation, the bald old man readily handed over his crutch: "it doesn't matter how you check, it's just my crutch, and it doesn't matter."

"It looks like..."

Mu Mu took a crutch and looked around. He asked the old man, "there is a little blood on your right shoulder..."

"That woman seems to have been assassinated on my right side," the old man said, holding his arm and sitting opposite Mu Mu. "Can I have my crutch back if it's ok? This is from the watchmaker who just mentioned. He gave it to me 10 years ago

"Er, blood test is still needed... Do you have any impression of the prisoner?"

"Although it has nothing to do with me, I think the prisoner should be a very fat guy. Before that woman screamed, I was hit by an elastic and very soft body..."

After the old man left the room, Mu Mu asked Gao Cheng and uncle: "how about it? Did any of them lie? "

Gao Cheng shook his head: "in this case, even the prisoners will not completely tell lies. Let's continue to ask questions."

The testimonies of the three people all have subjective judgment, but it is not without reference value. It is also one of the detective's work to infer and judge information clues.

The fourth one to enter the room is the fat housekeeper Qingmei yuedao, who is suspicious because of her obesity.

"Mr. Qingmei, your fingerprints were detected on the knife beside the cake..."

"Of course, after Madame blows out the candle, cutting the cake is my task as a housekeeper!" The housekeeper said angrily.

"Uncle Butler," Conan interposed from the side, "the light didn't come on immediately after the candle went out. Why?"

"Because I didn't wait for my wife's signal," the fat housekeeper said stupidly, "I used to blow out the candle and ring the 6 o'clock at night. When all the bells are over, my wife will ring her fingers and ask me to turn on the light, but this time the clock didn't ring right away..."

"By the way," Uncle pushed away Conan, staring at the housekeeper and doubted, "you guy... You're right next to the lady, but there's no blood at all!"

"Well, it seems that the prisoner is a big man. Maybe they are all blocked..."

Fat housekeeper finally wiped sweat left the room, leaving the eyes of the evening to continue to think of the party.

"Are there any big, fat, agile women in tuxedos among the guests?"

"I don't think so..."

Gao Cheng didn't attend the next question. He took the notes of the four people in front of him and went back to the banquet hall at the scene of the crime.

Judging from the situation of the scene, no matter who is a prisoner, they are bound to go to the scene for decoration. That is to say, a few people from the light side and the Baoke family who came in advance can do it. At that time, only these four people were at the party, and the other maids, cooks and watchmakers were not there.

It was said that the big clock, which had never been in trouble, didn't ring on time at 6 o'clock, and Mrs. Baoke was assassinated in such a short time. Gao Cheng and Conan go to the balcony together. Stained with blood is in the middle of the door frame of the French window and the balcony railing. It seems that the prisoner re opened and closed the door and window and then crossed the balcony railing. Gao Cheng looked at the blood carefully. It's strange that the blood on the doorframe is about the same height as the railing. If a person who is covered with blood runs away, it should not leave such a simple bloodstain scratch. It is much more chaotic. This scene looks like it was wiped by some tools. That is to say, after the prisoner killed Mrs. Baoke, the mechanism set up in advance was triggered to let the murder weapon leave the scene, and at the same time, the appearance of the prisoner escaping from the balcony was created. This is a reasonable inference, at least more reasonable than uncle's guess. Uncle thinks that the prisoner got Mrs. Baoke's blood in advance, and then smeared it here in advance... If it was prepared in advance, there would be more blood. Gao Cheng stands beside the railings, looks at the mouth of the well which is blocked by an iron frame directly below, and looks up at the bell tower like clock just above. If it is to set up a mechanism, the water well downstairs and the big clock are likely to be used... Gao Cheng's eyes are gradually solidified, and the whole person enters the thinking space with the big clock's walking. The actions and words of several people in the light side all flash around, and the villa time seems to go back to the time of the crime“ It turns out that's what happened... "Gao Cheng closed his eyes for a while, and his eyes became clear when he opened them“ He is the murderer. "“ Well Conan, who was still studying blood, looked back“ Can you think of it, too? " Gao Cheng looked at the guests waiting to be questioned in the room and said with a smile, "the prisoners have already stopped calling themselves up in the beginning."“ Well Conan raised his chin to meditate. On the other hand, the eyes are still worried. As time goes by, the guests have asked one after another. Most of the people on the scene are far away from the victim's wife Baoke, and there are not many people close to the balcony. Moreover, the testimony is almost the same. In the end, there are no prisoners who meet the characteristics. It was late at night and the police had to give everyone a result“ Well, the rain has stopped, "Mu Mu Mu said, looking out of the window." we have to let the guests go back first... Don't they have a clue yet? "
