Kei Suzuki handed the keychain to Conan, and then took a closer look at the study, only to find that in addition to the many books in this study, there were actually a lot of CDs. There is a bookcase dedicated to CDs.

Seeing Kei Suzuki staring at the CDs in the bookcase, the housekeeper Koike explained beside him, "We like classical music very much, so there are many CDs he picked up in the study. ”

When Conan heard the butler's words, he was taken aback and secretly said, "Classical music? When we're outside the door, isn't it an opera? ”

After hearing the butler's explanation, Kei Suzuki nodded and didn't say anything, but as soon as he looked up, he found a photo on the bookcase where the CD was placed. Judging from the appearance, it should have been taken by Mrs. Tsujimura and the deceased when they were young.

Of course, what caught Kei Suzuki's attention was not the photo itself, but the resemblance between Mrs. Tsujimura when she was young and her son's girlfriend, Miss Sachiko Katsuragi.

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

At this time, Mrs. Tsujimura also found the photo in Suzuki Kai's hand, and hurriedly walked over and said, "Why are you asking this?" This is an old photo from 20 years ago. ”

Conan's high fever at this time had already blurred his eyes, and he couldn't see the photo in Suzuki Kai's hand at all. Kei Suzuki thought that Mrs. Tsujimura was the murderer at the beginning, but at this time, it was suddenly discovered that Mrs. Tsujimura and Sachiko Katsuragi might be related, and there was probably a guess about why Mrs. Tsujimura killed the deceased.

In his mind, it was very likely that when he found out that his son's girlfriend was the daughter he left behind, he wanted to break up the little relationship. Person. It was only after the deceased, that is, her husband, found out that her husband was dissatisfied with her. And Mrs. Tsujimura found out that her husband knew about her relationship with Sachiko Katsuragi......

Thinking of this, Kei Suzuki suddenly felt as if 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 it the other way around?

At this time, Conan suddenly snorted, as if he was very uncomfortable. And then groan. With a groan, Conan fell to the carpet in his study.

Heiji Hattori also looked at the keychain in Kei Suzuki's hand, and just as Conan fell, he walked to the door of the study in three steps as two steps, and after squatting and looking at the crack in the door under the study, he showed a look of enlightenment.

After Xiaolan found that Conan had fallen, she hurriedly picked up Conan 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 get a doctor over." ”

Then he looked at the housekeeper and said, "Can you please take this child to rest for a while?" Well, please come back after you settle this child! ”

When Xiaolan heard this, she hugged Conan and followed the housekeeper out of the study.

After the housekeeper Fumio Koike took both Conan and Ran away, Mori Kogoro suddenly said, "Huh! Where did Heiji Hattori go? ”

Another police officer replied, "The young man asked me about the location of the Japanese-style room just now, and then went out. ”

As soon as the officer's words fell, Heiji Hattori walked in again, and he stood at the door and said, "I already know!" I already know the methods of the secret room, and who the murderer is! ”

Hearing the news, all the people who were still in the study were taken aback. Maori Kogoro looked at Hattori Heiji in disbelief, he always thought that Hattori Heiji, a famous detective in Kansai, was blown out, but he didn't expect that he had no clues at all now, and Hattori Heiji had already found the murderer.

At the same time, Maori Kogoro also felt that the eyes of other people in the book were also a little subtle, although they didn't say anything, but Maori Kogoro always felt that the emotions of contempt and contempt in the eyes of these people were all clearly projected.

Even Xiaolan and the housekeeper, who had already walked outside the study, couldn't help but pause. After hearing Hattori Heiji's words, Conan couldn't help but open his eyes wide and look at Hattori Heiji with difficulty.

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

Although Conan still wanted to stay in the study, at this time, how could he be let go by Xiaolan, who was already burned and confused? He was forced to leave the study by Xiaolan without letting go at all.

And in the study, Hattori Heiji said proudly: "Now, I'll let you see the evidence." ”

"Excuse me, officer, could I ask you to be the deceased?" I don't know if it's intentional, maybe because just now, Kei Suzuki said that Heiji Hattori is not like his father, or because Kei Suzuki is the commander here, Kaiji Hattori walked towards Kei Suzuki and wanted him to be the deceased in the experiment.

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

Maybe it's an illusion, Kei Suzuki and Kogoro Mori both feel that there is a little regret in Hattori's eyes.

The evidence has been collected, the photos of the murder scene have been taken, and all the physical evidence that should have been collected has been collected. Kei Suzuki ordered the body to be removed from the floor, and then asked the policeman to sit in the chair where the murder occurred.

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

Under the gaze of so many people, Hattori Heiji was not nervous at all. In other words, he has experienced more big scenes, so the small scenes of ten people can't make him feel pressure at all. His confident voice slowly spread through the study.

"At the time of the incident, all the windows were locked from the inside, and the only door that allowed access was locked. In this way, a closed room murder case without gaps is formed. ”

Kei Suzuki didn't squeak, and usually after such a long period of foreshadowing, there will always be words such as "but" and "but" that indicate a turning point are waiting for you. And this twist just overturns the previous conclusion, forming a completely opposite statement. Sure enough, Heiji Hattori did not disappoint Kei Suzuki.

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

"Gap?" Such a qualified praising has no one else except Maori Kogoro.

Heiji Hattori is very satisfied with Mori Kogoro for being so cooperative. He pulled out one of his hands in his trouser pockets, then pointed to the door of the study, and said, "That's right, it's the crack under that door!" ”

Maori Kogoro squinted his eyes, walked over with a face full of unhappiness, pointed to the door, and said, "Hey, hey, hey!" You don't mean to say that the murderer threw the key to the study into the deceased's pocket from under that slit? ”

"That's right!"
