Saturday, April 12th, afternoon, Kurokawa's house.

After watching the scene, Maori asked: "Twilight Police Department, Mr. Kurokawa was killed by a heavy blow to the head from behind when he was using a computer, and the murder weapon is probably a bronze statue that fell to the ground, and there are still blood stains on the three keys on the keyboard, which is the death message, isn't that the case?"

"Not bad. "We also think that's death information." ”

"Then why do you suspect Dr. Asai?" asked Maori.

"According to the investigation, the windows of the unmanned rooms in this mansion are locked, as are those in this study, so the outside culprits have been ruled out, that is, the murderer is in this mansion. The Twilight Police Department said, and then asked Mrs. Kurokawa Sanna and her eldest son, Mr. Daisuke Kurokawa, "Because of Dr. Asai's visit, you both went back to your respective rooms, isn't that right?"

"Yes. Kurokawa Sanna said, "My husband said that Dr. Asai was a very important guest, and he was talking about work. ”

"That's it. Daisuke Kurokawa said.

The Twilight Police Department asked the maid, Manami Nakazawa, "Miss Nakazawa, you said that there was a fierce dispute between Dr. Asai and Mr. Kurokawa, is that true?"

"Yes. Manami Nakazawa said.

"That guy diverted research funds to other places and slowed down the progress of research. He also wanted to use the fact that the research was not completed as an excuse for me to continue to invest in him. Asaika asked rhetorically, "Mr. Mori, how can you not quarrel like this?"

"It's a bit excessive. Maori said, then asked, "What about later?"

"Of course, I broke it off with him and asked him to give me the information he currently had. "Then he went upstairs to sort out the papers." ”

At this time, Miss Nakazawa went to the kitchen alone, Dr. Asai later went to the bathroom, and Mr. Yamashita was left alone in the living room. In other words, none of the five of them had an alibi at the time of the incident. "And the bathroom is at the staircase on the first floor, and Dr. Asai just had a heated argument with the victim, and there is ......."

"What reason do I have to kill him but to be angry. Asai said, "If you want to kill him, he will kill me, and I am ready to sue him." ”

"I see," Mori asked, "Dr. Asai, what is your birthday?"

"Why am I telling you this?" asked Asai.

"Uncle, I don't think Mr. Daizo Kurokawa knows Dr. Asai's birthday. Yamazaki said, "It is possible to know the birthdays of Mrs. Kurokawa Sanna, Mr. Daisuke Kurokawa, and Miss Manami Nakazawa. ”

Maori asked the three, "Which of you has a birthday in June?"

"Our birthdays are all June," Kurokawa Sanna asked rhetorically, "What's wrong with that?"

"Both, all of them?" Maori was taken aback.

"Hey, hey, Maori," the Twilight Police Department asked, with triangular eyes puffed up, "You don't think that death message meant June in English, did you?"

"Ahh So this murderer is Mrs. Kurokawa Sanna, and it's you. ”

"It's really funny, do you want to use such a boring joke to say that I'm the murderer? Kurokawa Sanna sneered, "Do you want a large pill of sleeping pills, Mr. Kogoro, who is sleeping?"

"Would a dying man have the heart to do such a troublesome thing, and if so, then the most suspicious person is Miss Manami Nakazawa. "According to the investigation, the combination of the letters on these three keys is the right name for the hiragana 'Ma, Na, and Mi'." ”

"Ah, all of them?" Maori was taken aback.

"Of course, there are only three buttons, and there are only those combinations when you turn them upside down. The Dusk Police Department asked angrily, "You don't think we can't even find out this, do you?"

"This—how is this possible? Maori laughed dryly, and then asked, "What else did you find?"

"Based on the blood stains left at the scene, there should have been blood stains on the murderer's body, so we investigated the clothes of the five of them and found that both Miss Nakazawa and Dr. Asai had blood stains on their bodies. And Mrs. Kurokawa and Mr. Daisuke Kurokawa's room is on the second floor, and they have time to change clothes. "So everyone in this mansion is suspicious except for Mr. Yamashita." ”

"Officer, you've all checked my and Daisuke's clothes," Kurokawa Sanna asked, "Our suspicion can be cleared, right?"

"It's not clear if you're hiding your clothes somewhere else. The Twilight Police Department replied, then added, "Miss Nakazawa was the first discoverer, and she said that she came here because Mr. Kurokawa didn't show up, and then she went to investigate with blood on her body. ”

"Yes. Manami Nakazawa said.

"I had changed my clothes and came here when I suddenly ran into an injured man with his blood on his body. Asai said.

This has been confirmed. The Dusk Police Department said.

Maori asked, "Dr. Asai, why don't you change your clothes since you have blood stains?"

"I'm not free," Asai said, "I came here during my lunch break, so I was a lot late." ”

"That's right. Maori said, then laughed, "By the way, just know the blood type of the blood on their bodies......"

"Coincidentally, it's the same. "Now it's been sent to the lab for a more in-depth comparison." ”

"Huh?" asked Maori, "what else do you want me to do?"

"It takes a lot of time, and if nothing else, I'm going to feed the mice at three o'clock in the afternoon. Asaika said, "I don't have time to go back to the Metropolitan Police Department with the Twilight Police Department." ”

"Huh?" Mori, Conan, and Ran winked together.

"What's the expression?" said Asai, "each of those mice is worth more than a million yen, but it's important. ”

"Ahem!" asked the Twilight Police Department, "Maori, what can you do?"

"Well...... Mori looked at Yamazaki.

Yamazaki asked, "I have a question about why this big desk is placed like this, not only in the middle of the room, but also with the door behind it, facing the window. Generally speaking, this kind of large desk should be facing the door with its back to the window, and it will leave some space in front of the desk, right?"

"Say it's because of Feng Shui. "Manami Nakazawa.

Daisuke Kurokawa said, "It seems that this is the reason. ”

"The Twilight Police Department," Yamazaki said, "I think if I find this feng shui master, I might be able to find out who the murderer is." ”

"By the way, it was the murderer who asked the feng shui master to teach Mr. Kurokawa to put the table like this," Mori laughed, "which allowed the murderer to attack Mr. Kurokawa from behind." ”

The Twilight Police Department asked, "Do any of you know where that feng shui master is?"

Yamazaki whispered, "Uncle." As he spoke, he made a gesture of digging something and offering it.

"Business card," Maori said with a smile after watching Yamazaki's movements, "the Twilight Police Department, if you meet a rich person like Mr. Kurokawa, that feng shui master will definitely send a business card to Mr. Kurokawa." ”

"It makes a lot of sense. The Dusk Police Department said.

"The business card cases are all in the drawer under the desk. Kurokawa Sanna said.

The Twilight Police Department opened the drawer and found a lot of business cards, boxes and boxes, with the year, some months, and even the exact date.

"Is it the end of this year?" asked Sanna Kurokawa.

Daisuke Kurokawa said, "Yes, January. ”

"It's late in the month, I can't remember the specifics. Manami Nakazawa said, "I think I saw it when I was helping to tidy it up." ”……
