Tuesday, April 1, morning.

Yamazaki ran to the Flying Fish Cleaning Company as Mori said, and saw Mori, Ran, and Conan standing in front of the fire alley next to the Flying Fish Cleaning Company, talking to a woman.

Yamazaki walked over, and at the same time, a man came out of the Flying Fish cleaning company, walked over first, and then instructed the woman to go and drive a flying fish cleaning truck next to it.

After Yamazaki passed, he looked at the scene, a man under the age of thirty fell to the ground with his head covered in blood, next to a bloodstained I-shaped steel ingot, and a harmonica at hand.

Early in the morning, Ran dragged Maori out of bed, let him change into sportswear, pulled Maori, and took Conan out for a run, only to run about 3,000 meters, and when he ran to a Flying Fish cleaning car in front of the Flying Fish cleaning company, Maori was a big step behind, and Lan and Conan had to stop and wait for him.

When Maori caught up, the three of them ran forward when they heard screams coming from the fire aisle next to them, and what they saw when they ran over was what they were now. Mori went to check and found that the man had died on the spot, and after calling the police, he notified Yamazaki to come over. Later, I learned the identity of the deceased, Mr. Tsunehisa Fujii, the director of the Flying Fish Cleaning Company, from the secretary to the president of the Flying Fish Cleaning Company, Mr. Hisashi Fujii. Ran also told Yamazaki that the man just now was Mr. Hidesei Nakayama, the president of Flying Fish Cleaning Company.

"What's going on on the roof?" asked Yamazaki, "Uncle Maori, have you been up there?"

"I had the cleaning company staff go up and take a look," says Maori, "and there was no one. ”

Yamazaki asked with a smile, "Uncle, if the murderer is one of the employees of the cleaning company, I'm afraid that even fingerprints and footprints can't be used as evidence now, right?"

"Well," Maori was stunned for a moment, "they all came out of the building opposite, it can't be." ”

Yamazaki glanced back and forth between Conan and Ran, who was dressed cooler, and Conan immediately blushed.

Soon after, the Twilight Police Department led the team to arrive, and after instructing the subordinates to investigate, they asked, "The first person to find the body was ......."

"It's me, Lord Police. "I found out when I heard screams during my morning jog." ”

"Morning, morning run?" The Dusk Police Department was taken aback, it didn't look like this guy should have gone out at all.

"Yes, Lord Police. Maori laughed, "I found out that I was a little fatter, so I came to move." ”

Seeing that the corners of the mouth of the Twilight Police Department twitched, Yamazaki, Conan, and Ran turned their faces away, and Numb Hisahiko covered her mouth and laughed.

Maori also saw it, and smiled embarrassedly, "I'm not talking about your ......" and then noticed that the face of the Twilight Police Department changed, and immediately changed his tone and said, "Ah, no, no, I mean your body is very suitable for you." ”

"Oh, really?" said the Dusk Police Department with a dark face, "Thanks for the compliment, I'll keep it up." ”

At this time, an identification officer gave him an ID card and helped Maori out of the siege.

After seeing it, the Twilight Police Department asked about the identities of Nakayama Hidesei and Hitoko Numu, and asked Mori about the situation. Afterwards, Nakayama led the group to his office, invited the Twilight Police Department and Mori to sit down on the couch of the reception, and asked Hisahiko to serve tea.

After thanking him, the Twilight Police Department asked, "Excuse me, when this incident happened, Mr. Nakayama was in this room, and Miss Numb, you were in the secretary's room next door, and you were all alone, right?"

"That's right. Nakayama Hidesei and Hitoko Numu said together, and then Hitoko Nugi asked, "Officer, do you mean we don't have an alibi?"

Nakayama said, "It should be so, it's still early before the start of work, there are only us in this building, and there is no one in the building next door, and no suspicious people have ever entered or exited, so it is normal to suspect us." ”

Numb Hisahiko asked rhetorically, "But, isn't this an accident?"

"I-shaped ingots are not something that can be rolled casually. Maori laughed.

"I see. Hitoko Numbi said.

At this moment, a voice came out, and the four people who were talking followed the voice, and it turned out to be Conan pressing something like a remote control on his desk.

"Don't mess around with other people's things. "Maori planted a mushroom on Conan's head.

"What is this," Conan said, touching his head, "as if he could see outside." ”

"By the way, this is a surveillance camera," Hisahiko said as she pointed to the monitor on the right side of her desk, "maybe ......"

The Dusk Police Department asked, "Mr. Nakayama, can you take a look?"

"No problem. Nakayama said.

At this time, Maori noticed a picture of a beautiful woman on his desk, so he asked, "Mr. Nakayama, may I ask?"

"This is my sister," said Nakayama Hidesei, "who died a few months ago." ”

"Ah, I'm sorry. Mori said, then changed the subject, "Flying Fish Cleaning Company is very famous in Rice Flower Town, and President Nakayama is so young, it's really amazing. ”

"This name was given by my sister. Nakayama recalled, holding the photo, " It happened to be the carp festival, my parents died in an accident at an early age, although there was a relief fund, but compared to the high prices brought about by the economic take-off, life was not relaxed, and when I went to college, but also because of the economic take-off, the tuition fee was unusually high, I had to do a part-time job, when I couldn't be busy, my sister who didn't continue to go to school because of no money came to help me, she helped me take a lot of work, and then contracted the work to others, so I gathered a group of people, and then found a senior, that is, Fujii, invested a sum of money, after graduating from university, the company was established。 Later, when the economy collapsed and the family services that made money were not good, we contracted a few streets and got up early and worked late to earn some hard-earned money. Because of the cleanliness, the owners of the buildings on those streets handed over the cleaning work to us, and slowly, our reputation spread through these owners, and the business improved day by day. My sister said, "Brother, one day, our company will go public." Speaking of this, Nakayama Xiuzheng's tears flowed, "This stupid girl, how can it be so easy to go public." Then he wiped away his tears and smiled at Lan and the silent others who were crying with him, "I'm sorry to say something strange." ”

"It doesn't matter. The Dusk Police Department said.

"By the way, speaking of which, I actually had a motive to kill Fujii. Fujii is ready to divest and reopen a cleaning company entirely of his own, taking some of the company's capable old employees with him. I heard that he found a young lady who was a big entrepreneur, and that young lady's father would not only help his company introduce business, but also help his company go public. "To be honest, after this morning's cleaning, it was time for me to have a showdown with Fujii. ”

"What!" "Numbi Hitoko was taken aback, "So, the Flying Fish Cleaning Company is going to be disbanded?"

"Don't worry, it won't be disbanded, I've saved millions of yen over the years, enough to pay Fujii. Nakayama Xiuzheng smiled, "It's just that our Flying Fish Company will be more difficult in the future." ”

At this time, an forensic officer came in with a plastic bag containing a harmonica and reported, "My lord, although this harmonica has Mr. Fujii's name on it, there are no fingerprints of him, not even any of them. ”

"Ah, I see. Maori exclaimed.

The Twilight Police Department was taken aback and asked angrily, "What do you understand?"

"This is a murder incident, the murderer threw Mr. Fujii's harmonica there, and when he picked it up, he pushed down the steel ingot that was set on the roof of the building, but because of the angle of his standing, he didn't see that Mr. Fujii hadn't actually touched the harmonica on the ground. Maori laughed, "And it was Mr. Nakayama who arranged all this and made the steel ingots fall from the roof, because Miss Numb and Mr. Nakayama are boyfriend and girlfriend, so Miss Numb will commit perjury for Mr. Nakayama." Then he noticed that Nakayama Hidesei and Numu Hitoko had strange expressions on their faces, and asked, "What's the problem?"

Hidesei Nakayama and Hitoko Numu laughed together, and Hitoko Numu laughed, "How can you say that I am boyfriend and girlfriend with the president." ”

Nakayama Xiuzheng smiled: "It's a pity, Mr. Maori's reasoning is wrong, Miss Numb is going to get married next month, of course, the groom is not me." ”

Hitoko Numbi smiled: "I came to the president's office after hearing the screams, and the president was here at the time, so it was impossible for him to appear on the roof." ”

Nakayama Xiuzheng smiled: "In the same way, Miss Numb could not have appeared on the roof of the building at that time. ”

"This ......" Maori had nothing to say.

"Well, if you two are not relatives, the testimony is valid. With that, he pushed Maori, who was standing in front of the forensics, away and looked at the forensics.

"We found a lot of footprints on the roof of the building next door, and there were also a lot of fingerprints on the door of the roof, but based on the marks on the edge of the roof, there were still residues, and we determined that the steel ingot was dragged by a plastic rope and fell," the forensic officer said. ”

Maori said, "By the way, that steel ingot must not have been on the edge of the roof. There are no fingerprints on the steel ingot, as long as you find the fingerprints and correspond to the fingerprints on the door, you can know who the murderer is, and the steel ingot must have been placed there by the murderer. ”

"Well, there are no fingerprints found on the ingot, but there are many fingerprints on the door, but they are all employees of the Flying Fish Cleaning Company. The forensic officer looked at Maori and smiled, "They said it was Mr. Maori who asked them to see if there was anyone." ”

"Mori?" the Twilight Police Department turned to Mori and yelled, "Mori Kogoro!"

"Yes. Maori said weakly, with a bitter face, standing up straight, "I was too tired. ”

At this time, Lan's voice came, "Conan, don't just open someone else's drawer. It turned out that Conan had opened a drawer under his desk and pulled out a telescope.

"This is what I use to see if there is any trash on the street. Nakayama said with a smile, "The street in front of the cleaning company should always be clean." ”

Conan smiled dryly and put the telescope back, then closed the drawer and moved it away, only to move it to the vicinity of Mori, where he was planted with a mushroom planted by Mori, who was trying to transfer his target, and then squatted on the ground with his head in his hands.

"Ahem!" Yamazaki asked Hisako Numbi, who seemed to be thinking about something, and was a little scared, "Miss Numb, what do you think of?"

"Well," Hisahiko said as she looked at Hidesei Nakayama, "I heard that the president's sister was killed by a steel ingot that fell from the sky. ”

"What?" Lan said scaredly, "this, this ......"

Numb Hitoko said, "Isn't it, it's too much of a coincidence, so I think it's a little scary, I don't know if it's that kind of thing." ”

Maori suddenly laughed, "Ah, I see. ”

"What do you understand this time?" asked the Dusk Police Department helplessly. ……
