"Conan, are you alright?"

Conan shook his head, his body felt heavy, as if he had been injected with water, and he felt tired with every step, but he still refused Harukawa's kindness in pride.

"Madame! You're back, these guys are? Walking into the diplomat's wife's house, a man who appeared to be a butler bowed respectfully to Mrs. Tatsumura, and then looked at the strangers he had never seen before.

"Hmmm! Butler Koike, where is the sir, these are my old friend Maori and his family, I am going to wait for them to meet the sir! Mrs. Tatsumura said, leading Maori and her party to meet the diplomat.

"Sir should be in the study, ma'am!" The butler said.

"Hmm!" Mrs. Tamura said she knew.

"Mom!" A young woman appeared in front of Harukawa and the others, and it should be the daughter-in-law that Mrs. Tatsumura wanted to investigate, Sachiko Katsuragi.

"Why are you here, I'm not your mother, I won't let you marry Guishan!" Mrs. Tamura's face was very bad, and she obviously didn't want to see this beauty, so that the woman with a smile didn't know why

"I asked Sachiko to come, and Dad has already agreed to our marriage!" A man appeared from behind, his hand on Sachiko Katsuragi's shoulder, comforting.

Mrs. Tamura said a few more words to the two of them, and then she took Qingchuan and the others up the stairs and went to the study with an ugly face.

Mrs. Dacun walked to the study on the second floor, several people followed, and an old man appeared at the top of the staircase, who seemed to be holding something in his hand, and several people were still thinking about it when they heard Mrs. Dacun say "Dad".

Mrs. Tamura said a few words to his father, and the old man went downstairs and left, and when he went to the study, Mrs. Tamura knocked on the door and shouted.

After shouting a few times and no one came to open the door, Mrs. Dacun was puzzled, took out the key to open the door, and entered, and saw a middle-aged man leaning on his hand in front of the desk, seemingly asleep.

Mrs. Tamura walked over, called, saw that there was no response, and wanted to wake him up, but his hand touched Mr. Tamura's body, Mr. Tamura's body fell, several people were surprised, Mrs. Tamura shouted anxiously, Hattori was beside her, and immediately touched Mr. Tamura's neck, with a sigh, helpless: "It's dead!"

"Xiaolan, call the police!" Maori hurriedly said to Xiaolan.

"Good!" Xiaolan hurriedly went downstairs to make a call.

The two high school detectives briefly examined the corpse, and then Hattori and Conan seemed to have found some clues, crawled under the desk and wanted to pick it up, but they didn't want their heads to collide together, Hattori felt pain, picked up the clues he found, grabbed Conan again, held his back collar, and angrily threw Conan to Xiaolan, who came back,

"Take good care of this kid, don't let him run around, how can you let a child see the corpse!" Xiaolan hurriedly caught Conan and nodded to Hattori.

Conan pursed his lips and disdainfully, quickly broke away from Xiaolan's arms, and went to investigate the scene again, wanting to find some clues and deduce who the murderer was.

Towards night, Officer Twilight came to the scene with his police, there were a lot of people, more than the usual case, this is a diplomat's residence, important people in the surrounding government, no more accidents are allowed, Officer Twilight's boss has put a lot of pressure on Officer Twilight, if he can't solve the case today, then he will explain today's case by accident, or "find" a "murderer".

Officer Twilight looked at his subordinates to investigate the scene, looked at the corpse and said the information of the deceased, and looked at Maori helplessly, as if he had been present in the recent cases, is this a coincidence!

Officer Twilight asks Mori if this is a murder case, and Mori touches the back of his head and says, "The deceased's case is probably suicide......"

Maori Kogoro was despised before he finished speaking, Conan pointed to the red spot on the deceased's neck, and wanted to say that it was poisoned, but Heiji Hattori said it for him first, Conan looked at Hattori with some surprise, and he didn't think that this black-faced boy really had some strength!

Poison! Maori and the others were a little surprised, asked, listened to Hattori's reasoning and the evidence at the scene confirmed that it was poisoning, and when they were still confused, Hattori said: "Judging from the body temperature of the deceased and the absence of corpse spots on the body, the deceased should have been killed between thirty minutes before and after we came in."

"Who is this young man, Brother Maori?" Officer Twilight asked, looking at Mori, who had a heavy local accent and didn't look like someone from Tokyo.

"His name is Heiji Hattori, and he seems to be a high school detective from Osaka!" Maori said disdainfully, just like looking at Kudo, why are these boys more famous than himself.

"Hattori Heiji, it's you! You are the son of the current sergeant of the Osaka Police Station, Heizou Hattori, who is studying in high school! Officer Twilight was surprised, and looked at Hattori with sweat.

"He's the son of the chief of the Osaka Police Department!" Mori looked at Hattori in surprise, Hattori didn't say anything, looked at the corpse, thought about the case, and didn't seem to hear the words of Officer Twilight and Mori.

Xiaolan looked at Hattori in surprise, and disbelief flashed in her eyes.

"Don't you think they're alike!" Qingchuan didn't know when he stood beside Xiaolan.

"Hmmm! That kind of temperament is exactly the same! Xiaolan said.

"That's for sure, detectives, and it's the detectives who stand at the top, the same name, they have an inhuman interest in the case, otherwise they wouldn't have been so famous at this age, and it also has something to do with their father!" Harukawa said.

Xiaolan was puzzled: "Father!"

After thinking about it, it suddenly dawned on him: "Uncle Yusaku is a mystery novelist, and Heiji Hattori's father is the Osaka Police Station, so they will become detectives when they are exposed to these things since they were children!"

"Hmm!" Harukawa smiled slightly, with appreciation on his face.

Xiaolan was a little happy, as if she had done something big.

"The windows of the study are locked from the inside, and there are no other entrances on the four sides, so there is only this door at the entrance, and the most likely person now is the person who owns the key to this door!" Officer Twilight touched his chin and thought about it, walked up to Mrs. Tamura and asked, "Mrs. Tatsumura, there should be multiple keys to this door, right?" ”

"No, there are only two, one with me and one with my husband!" Mrs. Tamura took out a key from her handbag and said, "My husband usually carries the key in his pants bag!"

"Really!" When Officer Twilight heard this, he was surprised, and hurriedly walked to the corpse, rummaged through the deceased's pants bag, and pulled out the pants bag completely, and suddenly, a key fell out of the double pocket.

"What!"

Conan, Hattori, and Ran were all shocked, and even Officer Twilight was surprised.

"What's wrong?" Maori asked, puzzled.

"Don't you understand? There are only two keys in this study, and when we enter, the study is locked, one on the deceased, and the other on Mrs. Dacun, who entered the study with us, and there is no other entrance, which means that the prisoner is killing the victim before locking the door and leaving, then this is a closed room murder case! Heiji Hattori said.

"Murder in a closed room!" Mr. Tatsumura's family was shocked, and Xiaolan suddenly realized, when the key fell out, Xiaolan was faintly suspicious, and only then did she understand when she heard Hattori's explanation.

Family and friends around me are related to this aspect, dad Maori used to be a policeman, and now he is a detective, his mother is the undefeated queen of the legal profession, Harukawa was an agent in his previous life, and observing the details around him is a necessary skill, and Kudo Shinichi is a famous high school detective......

"Xiaolan has become smarter!" Qingchuan said with a smile, Xiaolan in the past, I didn't understand this, and I don't know if she was influenced by them, or something else, if she thinks quickly, she must be a female detective.

"Around you, you always learn something!" Xiaolan is a little shy, if there was a case before, Xiaolan could only listen to the discussion between Shinichi and Brother Qingchuan, but she couldn't help herself, she always felt that she was not in the same world as them, even if one was a sweetheart, the other was a childhood sweetheart, and now she can finally keep up with them, although it is not much, but it is also an exciting thing.

Officer Twilight pulled Maori aside to discuss the case, and after seeing Maori's performance, the minister had to rely on him.

Seeing where Officer Twilight and Mori were wasting their time, Hattori said, "The victim must have been killed in the thirty minutes between 3:30 and 4:00, so hurry up and ask everyone for their alibi during this time!"

When Officer Twilight heard this, he pulled Maori and avoided Hattori and said, "Hey! Don't let this kid be defeated, Brother Maori! ”

As a police officer in Kyoto, if a high school student from Osaka solves the case, and the father of this high school student is still the director of Osaka, then the twilight face will be lost, after all, although the detective solved the case, Mori and Kudo Shinichi are both from Kyoto.

Harukawa took Ran's hand and smiled, looking at where Hattori and Officer Twilight were asking Mrs. Tatsumura's family about the alibi within thirty minutes, but all of them had alibi, and Conan listened while carefully looking for clues, and time was wasted.

After a while, Hattori seemed to reason something and ran out of the study, walking somewhere, Conan's body became more and more serious, and his body swayed, but Conan still insisted.

"Bang!"

A flash of light flew in Conan's mind, as if he had deduced this secret room murder case, until his weak body still couldn't hold on, and his body fell down as soon as he was weak, Harukawa kept paying attention to this, and as soon as he saw Conan falling, he immediately ran over and hugged Conan.

Officer Twilight saw Conan falling, and he was also worried and anxious, and immediately called his police to call a doctor, Harukawa picked up Conan, injected spiritual power into Conan's body, and asked Mr. Tatsumura's son, "I wonder if there is a place where I can lie?"

"Go to my room, it's right in the back of the hallway!" Takamura said.

Harukawa said thank you, and hurried out of the study, and when he walked out of the study, he happened to meet Hattori who came back, and it seemed that he was still holding a line in his hand, which seemed to be a fishing line, and Harukawa's mind turned to understand Hattori's reasoning, but now is not the time to say this, holding Conan to arrive at Takatsu's room, and covering Conan with a quilt.

But Conan still groaned in pain, his body trembled, suddenly, Conan's body straightened up, and fell down again, his eyes were blank, Xiaolan saw Conan like this, and hurriedly ran outside the entrance in fright, hoping that the doctor would come earlier, but Qingchuan was unhurried to input spiritual power, and he didn't see a worried look at all.
