Saturday, February 1st, afternoon, the study of the Tsujimura family.

Hearing Yamazaki say that the diplomat was poisoned, Maori asked, "Are you sure?"

"Yes. Yamazaki said.

"Sister Lan, go call the police. Conan said.

"Call the police?" asked Maori.

Heiji Hattori said, "If it's poisonous, it's a murder." ”

At this time, Mei Daizi's voice came, "Brother, I'm going down." Everyone looked, and Mei Daiko jumped off the windowsill.

"Look at what's worth noting. Yamazaki said.

Hattori Heiji asked, "How many keys are here?"

"Two handfuls, and the other is at my husband's. Tsujimura Gongjiang Liang said with the key in his hand.

Looking at the oval keychain with a small rugby ball, Hattori asked, "Where is the other one?"

Tsujimura said, "I guess I was taken by my husband." As he spoke, he wanted to touch the diplomat's pocket, but was stopped by Hattori Heiji, "You are also one of the suspects, so it's better for me to come." As he spoke, he stepped forward and searched for Tsujimura's body, who was sitting in an armless chair.

Yamazaki handed Tsujimura to Tsujimura to support him, took out his mobile phone, and while broadcasting Miyamoto Yumi's phone, he asked Tsujimura Tsujimura, "Where is the nearest disaster base hospital from here?"

Kimie Tsujimura said, "Nihon University Hospital in Surugadai, Kanda Ward, next door. Blood type AB. ”

At this time, the phone rang, and Yamazaki said: "Officer Yumi, we are in Nibancho, Kojimachi, Chiyoda-ku, and Midaiko is about to send a person who has been poisoned by an unknown poison to the Nihon University Hospital in Surugadai, Kanda-ku, and try to help clear a passage to get out, and by the way, notify the hospital to prepare blood type AB." ”

"Midaiko?" Officer Yumi was taken aback.

Yamazaki said, "That's it, thank you." After saying that, he hung up the phone directly.

At this time, Hattori Heiji, who was stretching his hand in Tsujimura's right trouser pocket, changed his face greatly, and then smiled: "This is interesting." As he spoke, he turned out his trouser pocket, and a key appeared in the compartment of the trouser pocket where the key was placed, and then wrapped it in a handkerchief and took it out.

Yamazaki said to Lan, who came back from the police, "Lan, help clear the road." As he spoke, he helped up Tsujimura, who was sitting.

"Okay. Lan said.

Maori said, "I'll help you." ”

"No need, uncle, I can do it. Yamazaki said as he carried Tsujimura on his back, "This guy should lose weight, but in terms of antitoxicity, being big sometimes has benefits." As he spoke, he walked out quickly, and Tsujimura's blood dripped all the way.

Maori looked at the keys on the table and said, "Both keys are here, which means that this could be a ...... together"

"Murders in a closed room. Hattori Heiji said with some excitement.

"It's not yet possible to say that this is a secret room. Conan touched his chin and asked, "Uncle, what do you think caused the wound?"

Hattori Heiji smiled: "I can't see that you look like a detective." ”

At this time, Mr. Tsujimura, Takazen Tsujimura, and Fumio Koike followed Ran in, and Mr. Tsujimura asked, "Gongjiang, what happened, how did you get poisoned? Also, who are they?"

"Ahem!" Mori stepped forward and smiled, "Down there is Mori Kogoro, a detective. ”

"What?" Tsujimura's people were taken aback, and Tsujimura Takazen said, "How did you find this moldy star in your home?" ”

"Well," Mori said, "Tsujimura must have been poisoned before we came." ”

At this time, the Twilight Police Department led the team over.

"Your Excellency. You're so fast. Maori laughed, "It's really hard." ”

"What do you want to say?" the Dusk Police Department's face changed.

Lan whispered, "Dad, the Metropolitan Police Department is near here." ”

"Huh?" said Mori with a straight face, "The matter at the Twilight Police Department is like this, Mr. Tsujimura has been poisoned and has been taken to the hospital. ”

Pointing to the blood on the ground, the Twilight Police Department asked, "What about this?"

Maori said: "Because I didn't know what poison it was, I bled out." ”

The Twilight Police Department asked, "What's going on?"

Mori told him what had just happened, and the Twilight Police Department asked Mr. Tsujimura, "There are only two keys here?"

"Yes. Tsujimura said.

"Where's this window?" asked the Dusk Police Department, "Are you sure Miss Maida was closed before she opened it?"

"Well, no. "But it's always been closed." ”

The Dusk Police Department asked, "There's no other entrance or exit here, right?"

"Of course. Mr. Tsujimura said with a smile.

"Then this can be preliminarily concluded to be a closed room murder. The Dusk Police Department said, then asked, "Have you seen any suspicious people?"

"No," said Koike, "and the siren never went off." ”

The Twilight Police Department said, "Well, the murderer is among you people. ”

"What?" the people of the Tsuji family were taken aback.

"Since it is highly poisonous, but it is not dead, it means that the poisoning has not been for a long time. Heiji Hattori said, "You don't look like you've been broken into here, so except for Mr. Tsujimura's suicide, the suspect is one of you." ”

"Who is this?" asked the Twilight Police Department to Maori.

"The son of Hattori-sama, the head of the Osaka Prefectural Police Headquarters," said Mori, "a high school detective Heiji Hattori." ”

Heiji Hattori said, "Hey, I said, don't get my dad involved." ”

"Osaka?" the Twilight Police Department laughed in Maori's ear, "you don't want to lose to him." ”

"Of course not. Maori laughed, then asked in a low voice, "Is there something wrong?"

The Twilight Police Department whispered, "Because of the matter of the senator of the friendly department, the police launched a joint operation, and now police stations across the country have sent liaison officers to the Metropolitan Police Department. ”

Maori smiled, "I see." ”

"It's a pity," the Dusk Police Department muttered quietly, "I'll be relieved if Kudo is here." ”

"What did you say?" Maori didn't hear.

"No, nothing. The Dusk Police Department asked, "What are the scars, and can you tell what the murder weapon is?"

"A small scar, about two millimeters long. Hattori said, gesturing, "It should be caused by something like the tip of a knife." Then he added, "By the way, the bleeding had stopped at that time, which means that it had been at least two or three minutes, so Mrs. Tsujimura Koe, who came in with us, could be excluded." ”

Seeing that Tsujimura Gonge seemed to be relieved, Conan was puzzled, and suddenly his heart jumped, and he felt uncomfortable.

"Strange, even if he doesn't know people coming in?" asked the Dusk Police Department, "but if someone pokes him, he should wake up." ”

Wait a minute, Conan walked to the front of the stereo, the stereo was playing opera just now, and most of the music stored in the stereo cabinet, Conan thought to himself, could this be to cover up the "ah" when he was poked? Thinking of this, he turned around and walked to the side, but inadvertently found a problem, he couldn't see the cabinet behind the desk. Hmm, what's the matter, my head is starting to get heavy? Muddy, what is this for me?

Maori said: "I must have been given sleeping pills. Then he asked, "Does anyone know what Mr. Tsujimura drank or ate?" and then, seeing that no one spoke, he asked, "When was the last time you saw Mr. Tsujimura?"

"When I had lunch. "Later, I came to him, but he didn't open the door, I didn't have the key, so I watched TV in the next room to the study, and I didn't come out until Koe and Mr. Mori came." ”

Tsujimura said, "I saw my husband before I went to Mr. Mori. ”

"I ate out with Sachiko at noon, and my mother arrived home shortly before she got home. Takazen Tsujimura said, "We went upstairs to look for Dad, but he didn't open the door, so the stereo should be turned on." ”

Wait a minute, Hattori Heiji thought to himself, this should be a soundproof room, and you can hear the sound outside, that is......

"I was instructed by the old man to chat with the neighbors in the small garden next to me and inquire about the affairs of officialdom. Fumio Koike said, "I saw that the young master and Miss Sachiko were back, so I came back to see what they needed." ”

Conan looked at his desk as he stepped back, giving way and moving forward.

The Twilight Police Department asked, "Who is Sachiko-sama and where is she?"

"It's my girlfriend. "She went to the hospital with her father, who is a sixth-year student at Todo Medical University. ”

The Twilight Police Department asked Maori, "Why did you just let people go?"

"It was the gentleman who carried my father's back that said," said Takazen Tsujimura, "and he told us to stay here, and if we wanted to go, we would go between me and Sachiko, because Sachiko was acting together, and as long as one of them stayed here, Sachiko, who was studying medicine, would follow." ”

Hattori Heiji smiled, "That guy named Yamazaki is good." ”

At this time, an inspector said: "Police Department, the photo has been taken." ”

The Twilight Police Department said, "Then you go and check the problem with sleeping pills, as well as the murder weapon." ”

"Yes. The inspector said.

Conan walked over to his desk, looked at the title, and saw that it was a book about the economy, history, geography, and other aspects of Britain. Conan looked up at the bookcase again, which looked like they had been taken from various compartments in the bookcase behind him. It seems to be no problem, but if it is combined with opera and sight......

At this time, the inspector said, "Police, we found this inside the keychain." As he spoke, he handed over the open keychain. ……
