The famous criminal in the world of Conan

After learning the identity of Hattori Heiji, Inspector Megure turned his attention back to the case.

He looked at the room layout around him and spoke while thinking.

"Inside the study, all the windows are locked from inside the room. So, if you want to enter from the outside, the only way is through the door."

"In that case, the only person who can kill Mr. Tsujimura is the one who holds the key!"

As he spoke, Inspector Megure turned around and asked Tsujimura Isao's wife, Tsujimura Kimie.

"Mrs. Tsujimura, who has the key to this study?"

Tsujimura Kimie reached into his bag and spoke without thinking.

"There are only two keys to this study, and one is in my hand."

As he spoke, Tsujimura Kimie paused.

"The other one is in my husband's hands."

"Your husband?"

Inspector Megure repeated, turning his gaze to Tsujimura Isao who was lying on the ground.

Bai Masong had been paying attention to what Tsujimura Kimie said, and when he heard her say that, he immediately reached into Tsujimura Isao's pocket.

After some searching, Bai Masong found a key in Tsujimura Isao's trouser pocket.

Bai Ma just let go and took out the key from the inner pocket of his pocket.

The key is shaped like a key ring at the back that can be opened and closed, with a key hanging in the front. When you open the key ring, you can see a piece of tape stuck inside.

Seeing the key appear before their eyes, everyone's eyes froze.

Hattori Heiji, as well as Conan, who was standing nearby with a runny nose, all became increasingly serious in expression.

Inspector Megure even exclaimed.

"How can this be!?"

Only Kogoro Mouri was still standing aside, making an expression as if asking "What's wrong?"

Hattori Heiji couldn't help but scold again,

"Don't you understand? The study door was clearly locked. This means that the murderer committed the crime, locked the door with a key, and then left."

"One of the keys to this study is in the hand of the lady who came in with us, and the other is in the double pocket of the victim's pants. This constitutes a perfect impossible crime!"

"This is a closed room murder case!"

Hattori Heiji's words were like a bolt of lightning, striking everyone present hard.

At this time, Hattori Heiji was thinking that this uncle who became famous recently did not really have real talent. He was able to solve these cases probably thanks to the high school detective who had disappeared - Kudo Shinichi!

So, now it’s time for the two high school detectives from Kanto and Kansai to compete!

A competitive fire flashed in Hattori Heiji's eyes. Thinking of this, he said nothing and walked out the door.

"Hey, hey, hey, detective boy, what are you doing?"

Kogoro Mori shouted when he saw Hattori Heiji walking out.

“Look for clues!”

Hattori Heiji left the study without even turning back, leaving only a few words behind.

"Don't worry about him,"

After examining the body of the deceased, Bai Masong stood up and said calmly.

"Our most urgent task now is to check the alibis of everyone present between 3:30 and 4:00 p.m."

"Um, Brother Bai Ma, why is it between 3:30 and 4:00 in the afternoon?"

"Curious baby," asked Officer Megure.

Bai Masong explained casually.

"Because the purple marks on the deceased's body have just begun to appear, it means that the time of death cannot exceed one hour. Considering the time we responded to the call, it was probably within half an hour before Detective Maori came in."

"Sigh!"

Inspector Megure suddenly realized what was going on and he immediately called Takagi Wataru.

"Takagi, call everyone in the room over and ask for their alibis."

"Yes, Officer Mumu."

Takagi Wataru agreed.

Soon, the housekeeper Fumio Koike, Tsujimura Isao's father Tsujimura Toshimitsu, Tsujimura Isao's son Takayoshi Tsujimura, and Tsujimura's fiancée Sachiko Katsuragi came to the study.

Inspector Megure and Hakuba Matsu questioned them one by one.

Butler Koike Fumio was the first to answer.

"I was just around the corner chatting with the neighbors between 3 and 4 today."

"Well, so that's the case. It seems you don't have time to commit the crime." Inspector Megure said while taking notes.

Bai Masong didn't say much, just listened quietly.

"Okay, then Mr. Takayoshi and Ms. Sachiko, you also came here not long before Mrs. Tsujimura Koue returned, right?"

Inspector Megure turned around and spoke to Takayoshi Tsujimura and Sachiko Katsuragi.

"Yes, officer, you are correct."

Takayoshi Tsujimura nodded in agreement.

"So, where were you when Butler Koike came to the door to greet Mrs. Tsujimura?"

Inspector Megure continued to ask.

"We went to my father's study, but the door was locked. We called him, but he didn't answer, so we quickly came downstairs."

Said Takayoshi Tsujimura.

"After I came down, I immediately met my mother at the gate."

Katsuragi Sachiko added.

"Yes," Inspector Megure looked clear, then turned and looked at the last one, Toshimitsu Tsujimura.

"So, Mr. Li Guang also came here after two o'clock?"

"Yes," said Tsujimura Toshimitsu, "I finally came here, but Ah Xun was locked in the study, and Gong Jiang went out first. I thought it was boring, so I stayed in the living room next to the study and watched TV there."

Inspector Megure listened, took notes, and then asked Tsujimura Kimie.

"When did Madam Gong Jiang go out?"

"I went out before one."

Said Tsujimura Kimie.

After listening to everyone's answers, Officer Megure thought for a moment and said,

"In that case, Mrs. Tsujimura Kimie and Butler Koike Fumio are the least likely suspects at the time of the crime. They both have clear alibis."

"Mr. Toshimitsu Tsujimura, Mr. Takayoshi Tsujimura, and Mr. Sachiko Katsuragi, none of them have a clear alibi."

After saying that, Inspector Megure felt that his analysis was good and asked Hakuba Matsu.

"Brother Bai Ma, how is my analysis?"

Bai Masong said nothing and did not comment.

He looked around. Tsujimura Isao loved reading and had a lot of books in his study, but the stack of books on the table looked like they were taken directly from the bookshelf, which seemed very abrupt.

Besides this, there is one more thing……

Bai Masong looked at the large shelf of records in front of him, and finally spoke and asked the housekeeper Koike Fumio.

"Does Tsujimura Isao like listening to CDs?"

"Yes, that's right," Koike Fumio said affirmatively, "The master likes classical music very much."

Classical music?

But………………

Just now he checked the record placed next to the deceased's table, and it was clearly an opera.
