Suzuki Kei handed the keychain to Conan, and then looked at the study carefully, but found that in addition to the many books, there were actually quite a lot of CDs in this study. There was a bookcase that was specially used to store CDs.

Seeing Suzuki staring at the CD in the bookcase, the butler Koike explained next to him: "We really like classical music, so there are many CDs he chose in the study."

When Conan heard the butler's words, he ate a lot and thought to himself, "Classic music? Didn't we play operas when we were outside the door?"

After hearing the butler's explanation, Suzuki nodded and said nothing, but as soon as he looked up, he found a photo on the bookcase where the CD was placed. Judging from his appearance, it should have been taken by Mrs. Tsujimura and the deceased when he was young.

Of course, what Suzuki Kei noticed was not the photo itself, but the fact that Mrs. Tsujimura, who was young, actually had some similarities with her son's girlfriend, Miss Kaneki Sakiko.

Suzuki Kei turned his head to look at Yukiko Kaneki, then looked at the photo again. He picked it up from the bookcase and said to Mrs. Tsujimura: "I said Mrs. Tsujimura, is this photo yours?"

At this time, Mrs. Tsujimura also found the photo in Suzuki Kai's hand and hurriedly walked over and said, "What do you want to ask about this? This is an old photo from twenty years ago."

Conan's high fever at this time had already blurred his eyes, and he couldn't see clearly the photos in Suzuki Kai's hand. At the beginning, Suzuki Kai thought that Mrs. Tsujimura was the murderer. At this time, he suddenly discovered that Mrs. Tsujimura and Yukiko Kaneki might have blood relationships, and probably had speculation about why Mrs. Tsujimura killed the deceased.

When he thought, it was very likely that when he discovered that his son's girlfriend was the daughter he had left behind, he wanted to break up the couple. It was just that the deceased, that is, her husband, and her husband became dissatisfied with her. After Mrs. Tsujimura discovered that her husband knew about her relationship with Kaneki Yuki...

Thinking of this, Suzuki Kai suddenly felt something was wrong. If the deceased found Mrs. Tsujimura's illegitimate daughter, it should be that the deceased was furious and killed Mrs. Tsujimura. Why is the situation just the opposite?

At this moment, Conan suddenly covered himself and groaned, as if he was very uncomfortable. Then after moaning, Conan fell on the carpet in the study.

Hattori Heiji was also looking at the keychain in Suzuki Kai's hand. Just as Conan fell down, he walked to the door of the study as two steps, squatted and looked at the crack in the door under the study, and showed a look of enlightenment.

After Xiaolan found that Conan fell, she hurriedly picked Conan up and shouted nervously: "Conan, what's wrong with you, Conan?"

Kei Suzuki reached out and touched Conan's forehead, and then said to a police officer next to him who had nothing to do: "Please go and invite a doctor to come over."

Then he looked at the butler and said, "Can you please take this child for a rest? Well, please come back after you have settled this child!"

When Xiaolan heard this, she hugged Conan and left the study with the butler.

After the butler Fumio Koike took Conan and Koran away, Kogoro Mouri suddenly said, "Hey! Where has Hattori Heiji been?"

Another police officer replied: "The young man just asked me about the location of the Kawabata room and went out."

As soon as the policeman finished speaking, Hattori Heiji walked in again. He stood at the door and said, "I already know! I already know the method of the secret room and who is the murderer of the crime!"

When he heard this news, everyone in the study was shocked. Kogoro Maori looked at Hattori Heiji in disbelief. He always thought that Hattori Heiji, a famous detective from Kansai, had all been whispered out, but he didn't expect that he had no clues at all now, Hattori Heiji had already found the murderer.

At the same time, Kogoro Mouri also felt that the eyes of the others in the book were a little subtle. Although they didn't say anything, Kogoro Mouri always felt that the emotions of these people's eyes, such as contempt, despise, etc. were clearly projected.

Even Xiaolan and the butler who had already walked outside the study couldn't help but pause. Although Conan felt uncomfortable after hearing Hattori Heiji's words, he couldn't help but open his eyes wide with difficulty and looked at Hattori Heiji.

Therefore, Conan saw that he was holding a ball of fishing line in Hattori Heiji's hand in his pocket.

Although Conan still wanted to stay in the study, how could he be let go by Xiaolan when he was already burned and confused? So Xiaolan forced him to leave the study without letting go.

And in the study, Hattori Heiji said with a proud look on his face: "Now, I will let you see the evidence."

"This police officer, I'm sorry, can you ask you to be the deceased?" I wonder if it was intentional. Perhaps because just now, Kei Suzuki said that Hattori Heiji was not like his father, or because Kei Suzuki was the commander here, Hattori Heiji walked towards Kei Suzuki and wanted him to do the deceased in the experiment.

Kei Suzuki looked at Hattori Heiji, and then said to the policeman who Hattori Heiji asked for directions just now: "You, go play the deceased."

Maybe it was an illusion. Both Kei Suzuki and Kogoro Mouri felt that Hattori Heiji had a little regret in his eyes.

All the evidence and other things have been collected, the photos of the murder scene have been taken, and all the physical evidence that should be collected have been collected. Suzuki Kai ordered someone to remove the body on the floor and let the police sit on the chair where the murder case was caused.

The others stood aside and looked at Hattori Heiji and wanted to know what he wanted to do.

Under the gaze of so many people, Hattori Heiji was not nervous at all. In other words, he had experienced more big scenes, and such small scenes of ten people could not make him feel pressure at all. His confident voice slowly spread in the study.

"At the time of the incident, all the windows were locked from the inside, and the only door that could be entered and exited was also locked. In this way, a murder case with no gaps was formed."

Suzuki Kai didn't say anything. Generally, after so long, there will always be words such as "but", "but" and other words that represent a turning point are waiting. Moreover, this turning point just overturned the previous conclusion, forming a completely opposite statement. Sure enough, Hattori Heiji did not disappoint Suzuki Kai.

"But there is still a gap in this seemingly perfect secret room."

"Void?" There is no one else except Kogoro Mouri for such a qualified supporting actor.

Hattori Heiji was very satisfied with how Kogoro Mori cooperated. He pulled out one of his hands that was inserted into his pocket, pointed to the door of the study and said, "That's right, it's the thin slit under the door!"

Kogoro Mouri narrowed his eyes, walked over with annoyance, and pointed at the door and said, "Hey, hey, hey! You can't say that the murderer threw the key of the study into the deceased's pocket from the slit, right?"

"That's right!"
