Sunday, November 2nd, Nagato Mansion, main house, bedroom of Nagato Michizo.

After Hattori Heizou left, Mori was also going to say goodbye, but Nagato Michizo asked the three of them to stay for his birthday party, and Mori pretended to excuse himself and agreed, and then Mori's mobile phone rang. Yamazaki arrived, but the janitor at the gate wouldn't let him in. The housekeeper, Musashi-nosuke, calls the porter and asks them to let Yamazaki in.

"Haven't asked yet, aren't you all together?" asked Hattori Heiji in a whisper to Conan.

"There's a tracing commission, and Yamazaki is going to do this. Conan whispered, "This commission has been done for a long time. ”

Hattori Heiji smiled: "No wonder Uncle heard that he was looking for someone, and his face was so ugly." ”

After a while, Yamazaki arrived, "Hello Mr. Nagato, I'm Yamazaki, Uncle Maori's assistant. ”

"Hello. Nagato Michizo said.

Yamazaki reported the results of today's investigation to Mori, but there was still no result, "Uncle, so far, the person's colleagues, relatives and friends have said that there is no news of that person, but if it is not credible, I don't know. It's not a way to check it like this, I think it's okay to start with his insurance. We now have his picture and ID number, we can look up his health insurance number, look up the hospital he went to recently, and then we can get someone to keep an eye on him as long as we pay for it. ”

"Okay. Maori said with some pain.

"What's going on?" asked Hattori Heiji in a whisper to Conan.

"The commission fee, the person who ran away owed the client 10 million yen, and the client said that he would give his uncle fifty percent of the money he recovered after finding someone. Conan chuckled.

"Well, that's not right," Hattori Heiji thought for a moment and asked with a smile, "What if I can't get it back?"

Conan shrugged, "Of course there's not a penny left." ”

"Wouldn't it? Hattori Heiji laughed.

"What's worse is that the cost of travel and food is added up, and my uncle has already posted at least 400,000 yen upside down. Conan laughed.

"It's miserable. Hattori Heiji laughed.

"yes. Conan nodded and smiled.

"I mean you. Hattori Heiji motioned for Conan to look behind him.

"Huh?" Conan looked up to find Maori's fist enlarged on his head, and he didn't have time to dodge a large mushroom planted by Maori, and squatted down in pain.

Mori shook his hand and told Yamazaki about Nagato Michizo's tracing commission.

"Mr. Nagato, have you been paying attention to Ms. Kotomi Akagi?" asked Yamazaki.

"Wouldn't it?" asked Lan in surprise.

Yamazaki asked, "Uncle Maori, do you remember a few of your elementary school classmates, do you know what the names of their marriage partners were?"

Maori thought for a moment and said, "I really don't remember much." ”

"Yes, I was following Kotomi, but the family disappeared all of a sudden. Nagato Michizo sighed, "I thought they were on a tour, but they never came back." ”

Yamazaki said, "Then, President Nagato, you have to be mentally prepared that they may be killed. ”

Nagato Michizo was silent for a moment, and said gloomily: "No need to check, I don't want to know anymore." ”

"Well," Yamazaki said to Maori, "Uncle, it's getting late, I'll go back first." ”

Nagato Michizo said, "Mr. Yamazaki, you can stay for my birthday party as well." ”

"No, thanks, I still have work in the evening. Yamazaki laughed. ……

In the evening, there were not many people attending Nagato Michizo's birthday party, only his eldest daughter Nobuko Nagato, second daughter Yasue Nagato and her husband Mitsuki Nagato, housekeeper Musashi Nosuke, secretary Hinata Aoi, Mori Kazuran, Conan and Hattori Heiji.

At the end of the party, Nagato Michizo announces the marriage of his eldest son, Nagahidetomi and Miss Hinata Aoi.

After hearing this, Nobuko Nagato walked away with a long face, and Nagato Mitsuki stopped Musashi Nosuke, who wanted to call her, "Don't worry about her, she's still single now, and she's the only one left." Then he smiled, "How can the protagonist Xiuchen not be here, I'll go and call him." He said and left.

Soon after, while Ran was talking to Hinata Aoi, Conan pulled Hattori out of the room, "By the way, Hattori, you recruited us here, right? ”

"Actually, I miss you. Hattori Heiji laughed.

"Come less. Conan flashed the anesthetic needle, "Let's be honest." ”

At this time, the cordless phone in the bedroom rang, and Musashi Nosuke answered the phone, it was Akira Nagato calling, "Please let Dad listen to the phone." ”

Musashi Nosuke looked at Nagato Yasue at the third bed of Nagato Road and shook his hand to himself, and told Nagato Kou, "The master is already asleep." ”

"Hidechen is gone, nowhere to be found. Nagato said, and then screamed in horror.

Mori snatched the cordless phone, "Mr. Bright, what's the matter, where are you now?" Conan and Hattori Heiji also gathered around Mori.

Nagato said scaredly, "I'm in the room directly below you, and someone turned off the lights and took a knife from behind...... Ahh

Maori and the others hurriedly ran to the balcony and shouted down, only to find a man with a bandage on his face and a knife in his mouth, walking out of the room, and after taking a look at them, he returned to the room.

Mori, Ran, Conan, Heiji Hattori, Yasue Nagato, and Nosuke Musashi ran out of the door of the room together.

"Hidetomi!" Hinata sat down weakly on the ground. ……

Mori and the others came to the downstairs room of the third bedroom of Nagato Road, and found that the door was locked, and there was a cry for help from Nagato Bright inside, Musashi Nosuke immediately went to get the backup key, but before the key was taken, there was a scream of Nagato Bright, and Hattori Heiji immediately ran away, "I'll go find the security guard to block it from the outside." ”

Immediately after, Musashi Nosuke brought a spare key, and Mori and the others entered the door and found that there was no one inside, and the balcony door was wide open, so he ran to the balcony and found that there was a rope that was still shaking, and Nagato Mitsuki was on the spike of the fence outside the main house, apparently dead.

"Bright, my light!" said Nagato Yasue.

"Hey, I didn't find the killer here," Hattori Heiji appeared downstairs, "what about you?"

"I didn't find it either. "He's not going to go up." Then he said, "Not good, President." With that, he turned around and ran, and Ran, Conan, and Musashi Nosuke followed.

After a while, Mori and the others came to the door of Nagato Michizo's bedroom, and when they called the door, they found that the door was also locked, but then the door opened, and Nagato Nobuko came out and said, "What are you doing, be quiet, Dad is still sleeping." ”

"Why are you here?" asked Hattori, who had arrived on his way.

"I heard the screams, and I was relieved that my father came to see me. Nobuko Nagato said, then raised his hand and slapped Musashinosuke, "Where have you been?"

"Yes, I'm sorry. Musashi said, bowing his head.

"Hey, what's going on with this detective in my family?" asked Nobuko Nagato to Musashi.

Musashi Nosuke said, "Miss, Mr. Mitsuki was killed by Young Master Hidetomi. ”

"Really?" asked Nobuko Nagato, "did my brother do that?"

"Yes. Musashi said.

"What do you mean?" asked Maori.

"I thought he'd do it one day, and the two of them would have a big fight every time they met. Nobuko Nagato said, "They have been friends since childhood, and they used to seem to have a good relationship, but since that incident, they have been incompatible." ”

Heiji Hattori asked, "What does that mean?"

"Twenty years ago, there was a fire in a hotel near here, and Hidetomi and Bright, who were both high school students, passed by, and the nosy Hidetomi broke free from Bright and rushed into the fire to rescue a girl who couldn't escape, and she is the Hinata Aoi today. "Hidetomi was severely burned on his face because of this, and from that day on, he didn't go to school, and he stayed in the house all day as a novelist." Of course, there was no girl beside her, so this woman took this opportunity to get close to Xiuchen, and became his father's secretary on his recommendation, and even wanted to marry Xiuchen. ”

Hattori Heiji asked, "So, where were you before you came here?"

"In the case of an alibi, I was upset that I was drinking in my room and calling my friends to complain, but I couldn't remember who to call because of the drinking. Nobuko Nagato said, "But just look up the phone number." After saying that, he returned to Nagato Michizo's bedroom.

Mori asked Ran to go to Michizo Nagato's bedroom, and then called the police, only to learn that a security guard had already called the police, so he called Yamazaki. Then Maori, Conan, and Hattori Heiji asked Musashi Nosuke to take them to the security room to investigate the surveillance video, but there was too much surveillance, so Mori had to stay and watch it slowly, and let Musashi Nosuke lead the security guards to search for the murderer, and Conan and Hattori Heiji also went. ……

Night, half past ten, Miyamoto's house.

Yamazaki, who had just come up from the Maidai restaurant and had just entered the door, received a call from Maori.

"Another incident?" Miyamoto asked.

"Yes, the killings. Yamazaki shook his head and said, then said, "I'm over." By the way, I don't think I'll be back tonight, so you don't have to wait for me. ”……

On the other side, the Nagato Mansion.

While searching with a flashlight, Conan asked Hattori Heiji, "Didn't you find a suspicious character just now?"

Heiji Hattori said: "No, I also asked the two security guards who were guarding the door of the main house, before and after the incident, only Mr. Mitsuki had gone out, it was to find Mr. Hidetomi, shouted a few times around the bushes and pools, and came back." ”

Conan asked, "By the way, what did you call me here for?"

Heiji Hattori said, "Actually, Chairman Nagato heard strange noises last night, as if someone was running in the hallway, and there were several strange sounds of something colliding. So I informed my dad, and I just didn't want to watch the boring cultural festival and came along. Originally, my father and I thought it was just a thief stepping on the spot, and we were going to get the stolen goods alone after the thief succeeded, but this is not my father's jurisdiction, so we can't leave the police down, and my father didn't worry about me alone, so I mentioned the Maori detective. It just so happened that President Nagato was looking for someone, so my dad recommended a Maori detective. In the end, I didn't think ......"

Conan said, "I didn't expect to steal a human life. ”

"But don't you think it's strange that there is a sleeping Kogoro, a famous detective who has become famous thanks to you. Heiji Hattori said, "It seems that the murderer is quite confident in his murder plan." ”

Conan said, "Or maybe the plan can't be changed anymore." ”

"Also, have you noticed the items left behind by the murderer near Mr. Mitsuki's body?" Hattori Heiji asked rhetorically, "The murder weapon is nothing, but since you want to escape quickly, you don't have to take off your hat and bandages, and even take off your gloves, isn't the murderer afraid of leaving fingerprints?"

In other words, the murderer is a person inside the mansion, and as long as he removes his makeup, he can blend in with the crowd. "And the murderer deliberately showed us his bandaged face, apparently to blame Mr. Hidetoon." ”

"At that time, we were the only ones in the main house, and the only one who could have done this was Miss Nobuko, who left the dormitory halfway. "But if she's talking to someone on the phone, as she said, she'll have an alibi." ”

"Let's go check it out, then," Conan laughed, "and she happens to be in the president's room right now." ”

"No, not really. Hattori Heiji said this, but his feet followed.

Soon after, Conan and Heiji Hattori entered Nobuko Nagato's room. The bed was a little wrinkled, the cordless phone was thrown on one side of the bed, there was a bottle of wine on the bedside table, the wine in the bottle had been half gone, and there was lipstick on the mouth of the bottle. It seems that someone once sat on the head of the bed while talking on the phone, and drank directly with a bottle.

"It seems that Miss Nobuko was very angry at that time. Heiji Hattori said, then spotting Conan rummaging through things, and whispered, "Hey, hey, Kudo, this could be mistaken for a thief." ”

"Don't worry, rest assured," Conan laughed, "I'm just a child." ”

"That's why I'm not at ease. Hattori muttered, "I'm not a child. ”

At this time, the phone rang, startling Hattori Heiji, and then found that Conan was answering the phone in Miss Nobuko's voice, and said in surprise: "You can find the frequency without trying this?

Conan glared at Hattori Heiji, signaled him to be quiet, and then pressed the speakerphone, and a man's voice came from the phone, "Nobuko, is what you just said true?"

Conan asked in Miss Nobuko's voice, "What?"

"Have you forgotten? You just said," the man said embarrassedly, "that one, to marry me." ”

Heiji Hattori immediately covered his mouth, afraid to laugh out loud.

"When?" said Conan, in Miss Nobuko's voice, "I don't remember. ”

"Not long ago, you called and said a lot of things, and I couldn't interject. The man said.

Conan asked in Nobuko's voice, "Be specific, when?"

"Ah, I'll see," said the man, "the time is from 10:04:31 p.m. to 10:16:57 p.m., that's specific enough." ”

Conan said in Miss Nobuko's voice, "That's enough, but something happened to my family, and I'm not in the mood to talk about it right now." Then he said, "You can call later." With that, he hung up the phone.

"That last sentence, well done. Hattori Heiji laughed.

"Ten o'clock in the evening is about the time of the crime. Conan put away his voice-changing bow tie, "Now it's certain that the person who bites the knife on the balcony and pretends to be Hidetomi can't be Miss Nobuko." ”

"In that case, the only one who can do this is Mr. Hidetomi himself," Hattori Heiji said, "but where can he hide after the bandages are removed?"

"Could it be that he has already had a makeover?" asked Conan.

"Then let's go to Mr. Hidetomi's room and have a look. Hattori Heiji smiled, "Of course, it's up to you to do it." ”

"You guy. Conan rolled his eyes.

Soon after, Conan and Heiji Hattori entered Hidetomi's room. The room was full of books, except for books.

Conan flipped through the phone and found that there was a recording on the phone, so he pressed it out and listened.

"Mr. Hidechen, I'm Yamada from "Literary Times", and the next delivery time is scheduled for one o'clock at noon tomorrow, and we will meet at the old place. 1:28 p.m. on October 31. ”

"I'm Yamada, and I've arrived at the coffee shop. 1 November 1 at 1:04 p.m. ”

"I'm Yamada, I've been waiting for six hours, I don't think you're coming, so I'll go back today. 6:55 p.m. on November 1. ”

Conan said: "November 1 is yesterday, and Mr. Hidechen did not go to the appointment, does it mean that ......?"

"I was killed," Heiji Hattori said, "if the murderer robbed and killed Mr. Hidetomi yesterday while he was away, and then infiltrated the mansion in his appearance, and then made this murder plan at night, and then killed Mr. Mitsuki tonight......"

"It is very likely that Mr. Xiuchen came over this afternoon without saying a word. Conan said, "It's not the same as Miss Nobuko's saying that you will quarrel as soon as you meet Mr. Mitsuki. ”

"Let's go to the kitchen and make sure. Heiji Hattori said, "Even if you are a murderer, you have to eat." ”

Soon after, Conan and Hattori Heiji came to the kitchen to inquire about something strange about Nagato Hidetomi in the past two days, and then learned that there was indeed something unusual. Nagato Hidetomi usually doesn't eat breakfast, and he doesn't usually eat much, but he even ate desserts that he doesn't eat often last night, and he also had breakfast this morning.

Hattori Heiji asked, "By the way, have you never changed the bandages on Mr. Hidetomi's face?"

"How could it be. The maid said, "Every three days, Miss Kang Jiang will help Young Master Xiuchen change his bandages, and I remember that they were changed only on the afternoon of the 31st. ”

Conan said, "There are other strange things, anything goes. ”

The maid asked, "Is it strange that there is suddenly a sheet missing from the house?"

"Hey, you can't be wrong, can you?" asked the cook.

"Probably not. The maid said, "We have counted several times." ”

After thanking him, Hattori Heiji and Conan came out of the kitchen, and Hattori Heiji said, "Hey, Kudo, this yard is being repaired, and there are pitfalls everywhere, do you think it is possible for Mr. Hidetomi to ......"

"Quite possibly. Conan said, "Mr. Hidetomi is somewhere in this courtyard, buried there. ”

"It seems that I guessed correctly, and after the murderer succeeded, he removed his disguise and returned to the crowd. Heiji Hattori said, "There are two things to do now, one is to make sure that no one escapes, and the other is to find the body of Mr. Hidetomi." Let's go, let's go to the security room to see how the surveillance video checked by the uncle is. ”

Soon after, Conan and Heiji Hattori met Mori in the security room and learned that no one had ever entered or exited the gate in the surveillance footage, and no one had climbed over the courtyard wall. And learned from the security guards that there were no suspicious characters.

Out of the security room, Hattori Heiji smiled: "It seems that the murderer is among these security guards." ”

Conan touched his chin and said, "Anyway, let's find Mr. Hidetomi's body first." ”

"What, do you still have any questions?" asked Hattori Heiji, "Is there a problem with my conjecture?"

"No, it makes sense. "But I always feel that there is something that we have overlooked, such as the motive for killing. ”

"In short, you can't go wrong with them. Hattori Heiji smiled, "Let's go, the police will arrive in a while, try to find Mr. Hidetomi's body before they come, and solve this incident." ”……
