On Monday, August 18, around nine o'clock in the evening, the burger restaurant opposite the office building of Hayato Nanjo.

When Yamazaki returned, he pulled Mori aside, and Conan joined in.

Yamazaki whispered, "Uncle, I already know who sent the advance letter, it's Miss Satomi Yoshino." ”

Sure enough, Conan thought to himself, so he was taken aback when he saw his uncle appear.

"What?" asked Maori, "how do you know?"

"It was Miss Satomi who told me that you had gathered them here so that she had no way to do anything, and that it was not a big sin to send threatening letters. Yamazaki said.

"Because of me?" said Maori, a little smug.

Yamazaki said, "Miss Satomi has already gone to inform the reporter to come over, saying that she wants to expose the true face of Mr. Nanjo. ”

"Really?" asked Maori, "Miss Satomi and Mr. Nanjo, do they have any deep hatred?"

"To put it simply, Mr. Nanjo killed Miss Satomi's boyfriend. Uncle, you can listen to Miss Satomi yourself in a while. Yamazaki said, "Mei Dai Restaurant is very busy tonight, and since this incident is over, I will rush back." ”

"Oh well. Maori said.

"Oh, by the way, Miss Satomi is going to strike at Mr. Nanjo's reputation by raising first and then suppressing," said Yamazaki, "Uncle, you'd better wait until after ten o'clock in the evening to see the direction of the wind before speaking." ”

"I see. Maori said. ……

Satomi Yoshino first raised and then suppressed, saying that the notice letter was written and directed by Hayato Nanjo himself, and did not cause major trouble to Hayato Nanjo, and although Tadao Ohno's testimony allowed the police to intervene, no evidence was found, and the police ended the investigation a month later. It's just that Satomi Yoshino's accusations are very convincing in the eyes of a wide audience, and there are too many similar programs on TV for the sake of his own career and killing his competitors. As a result, the prestige of Nanjo Hayato plummeted, and he slowly became a second-rate actor, and later a third-rate actor. ……

Tuesday, August 19, morning, Maori Detective Agency.

On the front page of this morning newspaper, there was a guide to the news titled "Death Defeat Detective Mori Kogoro in the Grim Reaper", and a small photo of Mori last night was attached, which made Mori so happy to see it that he couldn't close his mouth with a smile. ……

In the afternoon, Lan went to school to participate in club activities. Maori thought that he would have good luck today, so he went to play mahjong, and Conan, who was bored, followed. ……

It's nearly six o'clock in the evening, on the second floor of the 5-chome mahjong hall in Rice Flower Town.

Maori was in good hands today, sitting down for a few hours and winning a lot of draws. And this is a bunch of all the cards, and then touch a cake, Maori dizzy, how should this card play? I don't want a small hand suddenly stretched out from his arms, pushed to a card.

Maori saw that it was Conan, picked him up, and shouted, "What are you doing, boy! ”

"What's the matter, you're so lucky today. He said as he played a card, "Four cylinders." ”

"Huh, huh. Conan, in Maori's hand, knocked Maori's cards down.

"Uh," Maori looked at carefully, "it's really nonsense, it's still double." ”

"Forget it, I'll go home for dinner, my luck is really bad today. "The other family is leaving.

Shangjia asked, "What should I do if I am missing one of the three now?"

"It's okay," Xia Jia said with a smile, "that guy from Feitian hasn't left yet, and he will arrive as soon as he calls." ”

"He's at work today?" Mori said the lights in the signboard office across the street were on, "yes, it's Tuesday." ”

"He has no rest, he goes to work every day, and now he should hide in his office and do his favorite thing - counting money. Xia Jia smiled, and then used the mobile phone to contact Feitian, "We are missing one of the three now, do you want to come over?"

Hita's voice came from the mobile phone, "Oh, it's Hasegawa, are you playing mahjong? yes, yes, I'll be right away, uh, wait a minute, I'll be there within thirty minutes, and you guys should figure out how to do it yourself during this time." After saying that, he hung up the phone.

"So, Uncle Hasegawa, Uncle Okano, I'll play before Uncle Hita comes. Conan slipped from under the table to Maori's counterpart.

Hasegawa smiled and asked, "Little brother, do you also play mahjong?"

"No, you can't. Lan appeared.

"Lan, Sister Lan. Conan laughed dryly.

"Really, Conan, I heard from Yamazaki that you would come with you in the afternoon. Lan said, "Go, come home with me, and go to work if you're fine." ”

"But, Sister Lan, ...... here," Conan said.

"By the way, Lan, how about helping out for half an hour?" Okano said.

Lan said, "I don't want to play." ”

"Just half an hour. Hasegawa said.

"Yes, Lan, just half an hour. Maori said.

"Okay. Ran said, then called Yamazaki on Maori's mobile phone, "Well, I have some things, I'll be over in half an hour." ”

Yamazaki smiled: "It's okay, you play slowly, don't lose." After saying that, he hung up the phone.

Knowing that Yamazaki heard the sound of mahjong in the background, Lan hung up the phone embarrassedly. ……

More than twenty minutes later, after Lan touched a card, he put the card down, "Huh!"

"Draw your own hand again!" Maori shouted.

"Uh, what is this?" Okano blinked.

"Three, three yuan, four dark carvings, all the words touch!" Hasegawa felt that his chin was missing.

"Three, three times full!" exclaimed Maori.

"How can you play such a card? The three of them shouted together.

"This time I won again. Lan laughed.

The three of them paid the sign, and Okano said, "Then again, Mr. Hita is really slow." ”

Hasegawa said, "Then I'll make another call and take a look." He used a lot of phones, but no one was contacted, "It's strange, no one answers." ”

Okano said, "But the lights in his office are clearly on. ”

Maori asked, "Could something have happened?"

"By the way, he seemed to be panicked when I called just now," Hasegawa asked, "Could it be a robber?"

Maori said, "Let's go and see." ”

Soon after, Mori, Hasegawa, Okano, and Ran and Conan arrived at Hita Financial Company, but the door was closed, and no one answered.

Then, just as Maori was about to break down the door, a middle-aged man in his thirties wearing a short-sleeved shirt and trousers came over, "Isn't this the Maori detective, Mr. Hasegawa, Mr. Okano?

"It's Nanzawa," Okano said, "We couldn't wait for your president to play mahjong, so we came and called him directly." ”

Nanzawa asked, "Is our president still inside?" and opened the door.

"We saw that the lights in his office were on, but no one answered the phone. Hasegawa said, "I'm afraid something will happen to him." ”

Maori asked, "Nanzawa, why are you back at this time?"

"I forgot to bring my mobile phone. Nanzawa picked up the mobile phone from a desk.

The six Maori people came to the door of the president's office, but no one answered the door.

Maori asked, "Is there a backup key?"

Nanzawa said, "Because the president kept the safe in the president's office, there was no backup key. ”

"Then it looks like we're just going to have to crash in. Mori said, and slammed open the door to the president's office.

Inside the gate, Hida was foaming at the mouth and lying on his back on the ground, a large amount of banknotes scattered messily around him.

Maori stopped the crowd, looked at him, shook his head, and said, "He's dead." Lan, call the police, and call Yamazaki by the way. ”

Yamazaki received a call, but said he couldn't leave for the time being. ……

At about 7 p.m., the Twilight Police Department announced the preliminary investigation results, "The deceased Mitsuhiro Hida, 53 years old this year, the cause of death was suffocation caused by cyanide poisoning, and the preliminary estimated time of death was between 6 and 6:30 p.m. tonight." The key to the president's room was on the table in the room, and judging from the fact that the door was closed at the time and the lock of the window was also locked from the inside, it was impossible to commit a crime, that is, it was a murder in a closed room. ”

"That's true. Maori said.

"Judging from the video of the security camera on the front door of the company, the time when the employees here are Naozen Minamizawa, Takako Fujii, and Hiroshi Iino leave the company at 5:4. "After about an hour and twenty minutes, Maori you arrived at this place. Then he asked, "Mr. Nanzawa, you came back to get the mobile phone that you forgot to take, isn't that so?"

"That's right. Naozen Minamizawa said.

The Twilight Police Department asked, "Have you already informed Miss Fujii and Mr. Iino?"

"Yes, I called them over on a pager. Naozen Minamizawa said.

At this time, Takako Fujii, who was carrying a small bag and wearing a women's shirt and trousers, and Hiroshi Iino, who was wearing a short-sleeved shirt and trousers, were brought in by the police.

Takako Fujii asked, "Your posture, can't it be that our president is dead?"

The Twilight Police Department said, "Yes. ”

Takako Fujii lit a cigarette, "Oh, that scoundrel is finally in bad luck this time." ”

At this time, the forensic officer reported: "The victim has several banknotes on his right thumb and several banknotes with poison on them......"

"Ah, I see. Mori said, and then asked the three members, "Who is the one who gave this money to your president?"

"It's me. Hiroshi Iino asked, "Mr. Mori, is there any problem?"

"Then you're the murderer. Maori said. "Fei Tian must have a habit of adding fingers when counting money, and that's how you killed him. ”

"No, no, I didn't do it. Hiroshi Iino hurriedly shook his hand and said.

Naozen Minamizawa said: "In this way, when the president counts the money, he will make the money into a fan shape, lick his fingers and count it, and he will lick the thumb of his right hand. ”

"Ahem!" said the forensic officer, "Well, the poison on the banknote is on the fingerprints of the deceased, that is, the poison on the banknote was touched by the thumb when the banknote was touched. ”

Maori pointed to the coffee on the desk and said, "By the way, who brought this coffee in?"

Takako Fujii said, "I came before I got off work. ”

Maori said: "The murderer is you, I think you probably put poison on the handle of the cup." ”

The forensic officer said: "Neither the coffee nor the coffee cup have found any poison reaction, and in this office, in addition to the victim's right thumb and a few bills, there are two other places, that is, the doorknob on the inside of this door, and the lock button used to lock the door." According to the shape, the poison in these places is all fingerprinted, so it is likely that the victim touched these places after the poison was stained on his thumb. ”

The Twilight Police Department said, "Maori, in this case, this poison was brought in from outside. ”

"Fei Tian seemed to be a little flustered when he answered the phone, maybe something happened at that time, so that Fei Tian walked out of this room when he was halfway through the count, ran into something poisonous, and then went back to this office and locked the door," Mori said. ”

The Twilight Police Department said, "But he came across something to get poison on his hands." ”

"It looks like we're going to have to ask forensic people to look up all the places in the company," Maori said. ”

The Twilight Police Department asked, "Mr. Nanzawa, have you touched anything else besides your mobile phone since you came in?" and continued, "Please let us check your mobile phone." ”

"Nope. Naozen Minamizawa said, "I've always been with the Maori detectives. As he spoke, he handed the phone to the forensic officer.

"That's true. Mori said, and then noticed that Takako Fujii and Hiroshi Iino, who were standing at the door, were missing, so he shouted, "Miss Takako?

"I'm here. Takako Fujii's voice came.

The Twilight Police Department and Mori hurriedly ran over, and Conan followed, finding Takako Fujii boiling water in the kitchen.

The Dusk Police Department shouted, "What are you doing here?"

"Don't you know if you see it?" said Takako Fujii, "I'm going to boil water and make tea." ”

The Twilight Police Department yelled, "It's too messy, how can you touch anything here." ”

"Yes, got it. Takako Fujii turned off the gas with her left hand and inserted it into her trouser pocket.

The Twilight Police Department asked angrily, "I said, after you came here, you didn't touch anything other than this, did you?"

Takako Fujii said, "When I came, I went to the bathroom and wiped my face. ”

Hiroshi Iino came over and said, "I also used the bathroom once like her."

The Twilight Police Department angrily asked, "Except for the bathroom?"

Hiroshi Iino said, "I also used my computer for a while. ”

Maori noticed that Takako Fujii's cigarette ash had fallen and exclaimed, "I said you, don't drop the ashes at the murder scene." ”

Takako Fujii threw the cigarette on the ground and stepped on it, then spit it at Mori, "That's okay, Detective." ”

"Damn. Maori said angrily.

"Alright, alright. The Twilight Police Department patted Maori on the shoulder and comforted.

At this time, with a burst of flushing, Naozen Minamizawa came out of the bathroom, and saw the Twilight Police Department and Maori glaring at him, so he asked, "What's wrong with you two?"

Maori and the Twilight Police Department yelled together, "You are all suspects now, you are not allowed to walk around the scene casually!"

Takako Fujii said, "Well, I still want to use the bathroom." ”

Maori exclaimed, "Didn't you use it?"

Takako Fujii said: "It was washing your face just now, but now it's for convenience." ”

"Then please bear with me, let's check the bathroom. The Dusk Police Department said.

"I can't take it anymore. Takako Fujii said, "Women always have a few inconvenient days every month, so you should all understand." ”

"......" The Twilight Police Department and Mori were speechless, so they could only let Takako Fujii use the bathroom first, but asked her to hand over her personal belongings.

Takako Fujii emptied her pockets, "My pockets are empty, and everything is in this bag." Then he took out a pack of sanitary napkins from his bag, then took out a piece and showed that it had not been opened, "Now it's okay." Then he took the handkerchief again.

"Sister, let's use my handkerchief. "Conan contributed his own handkerchief.

"Oh well. "Takako Fujii took Conan's handkerchief and went to the bathroom.

The Twilight Police Department said, "Mr. Nanzawa, Mr. Iino, please hand over your belongings as well." ”……
