"What's the doubt?" Conan asked.
"The most special thing is undoubtedly the one left at the scene of the car accident..."
"Hey, let me tell you," Yu Jiang interrupted Datehang angrily, "Now shouldn't you be able to determine why the deceased died? If it was an accident, it would be enough to send the deceased to the hospital for a death certificate, right?"
Mouri Kogoro nodded: "Yes, yes, there are no external injuries on the deceased's body. My guess is that he died accidentally."
"Look at the body clearly, uncle!!" A young and clear voice sounded from below the crowd.
Everyone looked around and saw Conan pointing at the corpse and saying seriously: "This must be together..."
"Poison."
"Yes! Poison!" Conan agreed subconsciously and quickly looked up in shock.
The person who made the inference of death almost at the same time as him was the famous detective Hattori Heiji from Kansai.
Datehang had just arrived and had not had time to check the condition of the corpse. Hearing this, he slowly approached and squatted down next to the corpse: "In other words, there is a tiny pinhole on the edge of the hair root of the deceased. In addition, the corpse An iron needle that was suspected to be a murder weapon also fell next to it. It really looked like someone had been murdered with a poisonous needle.
"Mr. Mori, what was the state of the deceased when you found him?" Datehang looked up at Kogoro Mori.
The uncle scratched his head: "He was sitting on a chair, supporting his face with his wrists."
Hattori Heiji: "That should have been deliberately staged by the murderer after committing the crime."
"But just based on this, we still can't rule out the possibility that the deceased committed suicide, right?"
Hattori Heiji was speechless: "Don't you understand yet?"
"There were purple marks caused by hypoxia on the lips and tips of the hands and feet of the deceased, and there were bleeding spots on the conjunctiva of the eyes, but there was no evidence of drowning or suffocation in other parts of the body." Date Station stood up and slowly He said, "That means the murderer used a poison that paralyzes the nerves and can cause death, right?"
He pressed the surface of the body with his gloved hand again: "The deceased has not yet completely cooled down. According to the rule of 1-2 degrees of temperature drop per hour, the time of death of the deceased should be half an hour to an hour ago. As far as I know, the body It was discovered by you all half an hour ago, so the murderer must have poisoned the deceased within thirty minutes before you entered the study."
Yujiang grinned: "It's so interesting. The Da Cun family is located in a remote location, with sparsely populated high-end residential areas within a few miles. Moreover, there are no signs of being broken into the windows or doors of the Da Cun family. It seems that the murderer is there. In this house, it might be one of these people in front of you."
"..."
The room in the study was silent.
Not only the members of the Tatsumura family, but also the detectives looked at Date Hang with strange eyes.
"Ah, ah!" Conan sneezed loudly, "It turns out there are no reliable police officers in the police force!"
His words drew him hostile looks—mainly from Hattori Heiji.
Conan smiled.
Oops, I almost forgot, Hattori Heiji's father is the boss of the Osaka Police Headquarters. He grew up surrounded by police, and he would definitely get angry if he heard bad things about the police.
"Mrs. Tatsumura." Datehang didn't take Conan's childlike words to heart. He asked Tatsumura Kōe, "Who has the key to this study?"
Damun Gongjiang took out a key from his handbag and showed it to the police: "There are only two keys in the study, one of which is this one, and the other one is with my husband."
"Your husband?"
"Yes, he always likes to keep his keys in his pants pocket."
Idahang gave a wink to the Forensic Division police officer who was responsible for examining the corpse, and the police officer immediately took out the contents of the deceased's trousers pocket.
There was indeed a key in the small bag in his pocket, and the key was attached to a keychain with a butterfly pattern.
As soon as the key came out, most people in the room were shocked.
Datehang was confused.
Yujiang roughly guessed something based on everyone's expressions: "It seems that Mrs. Gongjiang came back with Mr. Maori and the others, right? I'm afraid that when these people entered the study, the door of the study was locked with a key. In other words... …”
Datehang understood, and his expression became more serious: "In other words, this study is a secret room, and this is a secret room murder case."
As a criminal policeman, he has not encountered many secret room murder cases, but every one of them is classic.
There is no doubt that the key to the investigation lies in how to crack the secret room.
There is no real impossible crime. The murderer must have used some kind of law-abiding method to create the illusion of a secret room.
"How is this possible..." Uncle Maoli was confused.
Hattori Heiji glanced at him secretly, becoming more and more convinced that it was Kudo Shinichi who was giving him ideas behind Mouri Kogoro's back. Otherwise, with this uncle's ability, it would be impossible for him to be able to handle any case as the newspaper said. .
Mao Lilan looked at Hattori Heiji and suddenly said to Yujie: "Teacher Shimizu, do you think... Hattori-kun looks a lot like you?"
Yujiang: "???"
"Well, to be honest, I think you all look a bit like Shinichi." Mao Lilan said sheepishly, "Maybe I'm wrong. Sometimes I think Conan also looks like Shinichi."
Yu Jiang: "..."
There are so many people who look similar to Kudo Shinichi, is Kudo Shinichi the template? ?
His face was directly copied from that of his junior brother, and the resemblance has nothing to do with him.
"So, what happened to Hattori Heiji? Why did you show up at Tatsumura's house?" Ikue asked in a low voice, "Mr. Mori received a new commission?"
"You guessed it right. In fact, it was Mrs. Kimie who commissioned my father to investigate Miss Sachiko Katsuragi. Hattori-kun said that Mrs. Kimie was jealous that her son's girlfriend was too good, so she was dissatisfied..."
"No wonder he is called the Kudo Shinichi of Kansai. His views hit the nail on the head."
"Ah? Kudo Shinichi from Kansai??"
"That's what the Internet says."
While Yu Jiang and Mao Lilan were chatting, Datehang had already started talking separately to confirm their alibi.
The housekeeper Xiaochi has been chatting with neighbors at the door. More than one person can testify to this, and the alibi is valid.
Takayama Takayama and Sachiko Katsuraki arrived shortly before Kimiko Tamamura returned home, and then they went to Tamamura Isao's study together. Because the study door was locked, they called Tamamura Isao and got no response, so they called again. Went down.
In other words, if their testimony is true and valid, Isao Tatsumura would have died before that.
Isao Tatsumura's father had been alone in the living room next to the study watching TV since two o'clock in the afternoon. No one could prove this to him.
In addition, since Tamura Kimie went out to find Mouri Kogoro at one o'clock in the afternoon, her alibi was the strongest.
