After meeting with Mumu police department and others, they had a simple greeting and soon returned to the scene of the crime again.

"At that time, we heard the sound of broken glass... Both the entrance door and the windows in the room were locked, and the murder weapon could not be found at the crime scene... So according to our judgment, this was a secret room murder."

When the police began to investigate the scene, Bai yanzhenyu told the Mumu police department the story of the incident and told everyone's reasoning.

"Secret room..."

Mu Mu's police department touched his chin and analyzed: "but it can be inferred from these that he killed. Is it a little hasty? Maybe there is another possibility that he broke the glass with a murder weapon after committing suicide, and then threw the murder weapon out."

"No, absolutely not."

Sakabe Pingci came up and interrupted, "we were downstairs. When we heard the sound of broken glass, we immediately looked at the window. Absolutely no knife fell out."

"Yes, and look at the blood here."

Bai Yanzhen Yu stretched out his hand and pointed to the bloodstain on the floor, adding: "if the dead threw the knife out of the window, there should be blood drops near the window, and the bloodstain here is obviously the trace of housekeeper chongsong dragged by the murderer."

"What you said is very reasonable. It seems that this is indeed a murder case."

Mu Mu's Police Department agreed with Bai Yan Zhenyu's judgment, and then asked, "in that case, why was the glass broken?"

"Well..."

Hattori scratched his head and guessed: "it is likely that the murderer accidentally broke it when arguing with the victim, or the murderer saw us from the window and wanted us to come to the scene, so he deliberately broke the glass with a chair."

"According to the bloodstains, the murderer killed housekeeper chongsong outside. No matter how careless, he won't break the glass inside, so I agree with the second guess of the service department. The murderer deliberately led us here."

Baiyan Zhenyu's eyes twinkled. After telling his judgment, he concluded: "but no matter what kind of possibility, one thing can be confirmed, that is, when the glass broke, the murderer must still stay in this room."

"I see, Takagi," the Mumu police department called officer Takagi and ordered, "go and investigate what others were doing at the time of the crime."

"Yes, Mumu police department." officer Takagi answered and took several policemen to investigate.

……

Soon after, police officer Takagi returned to the scene and reported: "according to the investigation, during the time period of the crime, most of the servants gathered in the restaurant for dinner, which can rule out their suspicion of committing the crime. If there is no clear alibi, there are only these five here."

The five people mentioned by officer Takagi are the three moriyuan family who have already finished their meal, miss piantongfeng who stayed here, and Sakuragi Yousi who was ordered to find the gray kitten.

"Well, I see."

After listening to officer Takagi's report, Mu Mu's police department nodded if aware and said to the forest garden owner and others: "I think I must have a separate question with you later. At that time, I will check your things, so please go back to your room and wait."

The owner of the forest garden and others did not object and returned to their room. After arranging to search for the murder weapon, the Mumu police department began to ask these five people one by one.

Baiyan Zhenyu and Pingci of the kimono Department came to the door of the villa to breathe and exchange views on the case at the same time.

Sakabe looked at Baiyan Zhenyu and Conan for the first time. There was a sense of war in his eyes. He smiled and asked, "Kudo, Baiyan, how many doubts have you found?"

Conan glanced at sakabe, stretched out four fingers and replied, "everywhere."

"So you've found four places too..." Hattori showed such an expression for the first time, and then asked Bai Yan Zhenyu, "Bai Yan, what about you?"

"I... Found five places." Bai Yan Zhenyu smiled calmly and gave an answer that surprised both service department Pingci and Conan.

"First, why did the murderer take the murder weapon away from the scene? Since it was a premeditated crime, it would not leave fingerprints on it. If the murder weapon was kept at the scene, it could lead to a false suicide;"

"Second, the blood dragged on the floor, why did the murderer drag the body into the inner room;"

"Third, only the light in the room where the body is located is turned on. Will the killer turn off the light in the outer room when he fled?"

"The fourth and most suspicious point is why the gray kitten appeared at the scene."

Conan kimono Department Pingci said the four doubts they found, then looked at Bai Yan Zhenyu and asked, "what's the fifth doubt?"

Baiyan Zhenyu didn't sell off. He said directly, "the fifth doubt is that yingtingyousi is wearing a sapphire necklace with the same style as Miss piantongfeng. That special style is by no means a simple coincidence. It makes sense."

"Sapphire necklace?"

Conan and the service department looked at each other for a second, thinking silently, and there were some guesses in their hearts.

More than ten minutes later, Mumu police department also completed a separate interview with the five suspects and told Bai Yan Zhenyu and others the results.

The owner of the forest garden made an appointment with the housekeeper chongsong at dinner, so he waited for the housekeeper chongsong in his room at the time of the crime;

At that time, Baihe River in Senyuan took a bath alone in his room. After taking a bath, he heard the screams of distant mountains and leaves, and then came to the scene from the room;

Senyuanju people also stay in the room alone, reading magazines and listening to music as usual;

In order to find the grey kitten, Sakuragi Yousi had been walking around all the floors of the villa;

Piantongfeng, who seems to be the most unlikely, is the most suspicious person, because she claims to rest alone in the room, but in order to invite her to take a bath, Senyuan Baihe River once called her in her room, but she didn't get a response.

While the people were analyzing the information, a police forensics officer suddenly shouted, "Mumu police department, please come here."

"What's the matter?" Baiyan Zhenyu and others heard it, and then followed the Mumu police department to check the situation.

The forensics personnel pointed to the door lock position of a French window and reported: "Mumu police department, there is a little blood on the inside of the door lock of the French window."

Bai Yanzhen Yu gathered up to observe carefully and judged: "it's like a trace caught with blood stained gloves. In other words, the murderer closed the French window after the murder."

After judging this, the sixth doubt follows, that is, what is the purpose of the murderer to close the French window.
