"Impossible! There is no other way to enter this secret room!" Hattori responded the most intensely to what Kudo said.

"Did you forget?" Kudo said: "When we entered the room, there was an opera playing in the room, and there was a pile of books on the desk of the deceased. The opera was to eliminate the possible screams of the deceased, while the book was to block the deceased and provide a visual cover."[]

"Hmph, hahaha." Hattori remembered that Matsuda deliberately looked at the desk when he was talking to him, but he thought he had cracked this method and did not pay attention to the books: "Whose troublesome thing is the murderer trying to cover up??"

"That's... Hattori Heiji!" Kudo said: "Of course it's not just you, but also Mr. Maori who entered this room with you. As long as anyone present saw her murder scene, the perfect secret room she arranged would be destroyed."

"So? Could it be?" Hattori thought of a possibility.

"Yes, the murderer is to enter this room with you, and then approach the deceased while your attention is focused on the opera... The murderer is you! Mrs. Tsujimura!!"

"Madam, killing the master? It's impossible!" This abrupt statement is unbelievable.

"Can you say?" Kogoro turned his head and asked Kudo: "When we just entered the room, Mr. Tsujimura was still alive?"

"That's right, at the beginning, Mrs. Tsujimura probably used an anesthetic drug to let the deceased fall asleep, and then pretended to ask the deceased to take the opportunity to kill him." Kudo stared at Mrs. Tsujimura who bowed his head and said nothing: "If the anesthetic drug has a strong effect and the poisonous needle is heavily poisoned, the deceased will die in an instant."

"But if we check the ingredients of sleeping pills from the dead, then this technique will be..." Megu still a little disbelief this time it could be said to be extremely bold.

"No." Hattori returned to his calmness: "We have always concluded that the deceased was killed before we entered this room. Even if it was found that the deceased had taken sleeping pills, they would not think about it. The murderer deliberately found the detective here in order to use the blind spot of their thinking that the murderer could not kill people under his nose. Is it right, Kudo?" Damn~~ Is this the truth that Matsuda believes? After Kudo's confirmed reply, Hattori immediately said: "Then you can prove it. Mrs. Tsujimura did not take out the suspicious action of taking out the poison needle at that time."

"That's right." Kudo picked up the key on the ground: "Madam Tsujimura did not have the suspicious actions of the god demon, because the poison needle was in her hands at that time. It was on this key."

"On the key?" Hattori has completely become a vocal worm.

"Yes." Seeing this guy who was trying to challenge him, Kudo's dark heart began to feel proud. The feeling of vanity that loves to show off made him flutter: "Madame Tsujimura's key ring has the same design as this key ring, so Madame Tsujimura's key ring can also be opened. Can you open the key ring and let everyone see the design inside?" The last sentence Kudo said to Madame Tsujimura next to him.

Of course, the so-called dark heart and vanity are all imposed on Kudo by Matsuda, who is hiding in the corners of the corners. After Megu found the key ring with grooves from Mrs. Tsujimura's bag, the most powerful evidence also left Hattori speechless.

After Mrs. Tsujimura angrily accused her husband Tsujimura of evil deeds, she also admitted that she was the murderer of this murder. The motive involved the secret past twenty years ago and the intrigue of those high-ranking officials. After solving this matter, Kudo finally couldn't hold on. After saying a few words in the scene, Kitanawa walked out of the room with difficulty.

Come on, come on, little Kudo. Matsuda, who was hiding in the corner, began to smile again. He fully saw two incredible events of the famous detective in one day, which is gratifying. When Kudo jumped down the stairs to get rid of Xiaolan, Matsuda quickly grabbed him and flashed into the toilet.

Under Kudo's miserable screams, Conan Edogawa turned back to Conan. Before he could speak, the toilet door was pushed open by Xiaolan. A petite figure inside sat on the toilet, and there was a vulgar figure shaking in front of him.

"Officer Matsuda? Conan?" Xiaolan looked at the two people in the toilet in confusion. It was Shinichi's voice: "Why are you here? Conan, do you know? I'm looking for you everywhere."

"Haha, Xiaolan. I saw Conan sweating a lot, so I found him a little bit." Matsuda stood up with a smile and gently pushed Xiaolan out: "Don't worry, I've been taking care of that little devil."

Looking at Matsuda's expression of being very happy, I was very happy, and listening to Conan saying "I'm fine, Sister Xiaolan", Xiaolan was pushed out before she could react.

"Have you seen Shinichi?" Xiaolan, who had been slowing down several times, asked this question weakly through the toilet door.

"Shinichi? That high school detective kid?" A gap was opened in the toilet door, revealing Matsuda's face: "It seems that he has hundreds of episodes of the case that have not been resolved, so I'll take a step first."

Hundred episodes? Case? Although Xiaolan was puzzled by the toilet door that was closed again, she also had a certain understanding of Officer Matsuda's neuroticism and stopped asking questions. She only knew that Shinichi left her again and again, without a reason, and at the same time there was no time limit worth looking forward to.

Xiaolan's steps away seemed to be a heavy hammer hit Conan's heart. He lowered his head, and the black-framed glasses flashed a sad light. After a long time, Conan raised his arm that looked like a thousand pounds and said without any emotion: "Give it to me."

"What?" Matsuda pretended to be ignorant: "Can you tell me a little clearly? Little friend?"

"Give me your phone!!!" Conan said gritting his teeth.

"Mobile phone!?" Matsuda took out his hand: "Oh, then again, it seems that everyone is using a flip phone. What's the best thing about this thing? Does Japan only produce such a mobile phone? When it comes to thinking that Kudo, Koran, Yuanzi, Sato, etc. seem to use flip phones, Matsuda couldn't help but maliciously guess whether Aoyama Takahara had any quirks.

"Give it to me quickly! You bastard!" Conan stood on the toilet agilely and rushed towards Matsuda.

However, Matsuda gently stretched out his hand and pressed Conan's forehead, allowing him to stand on the toilet and keep playing the big windmill game: "Little friend, if you have something to say, don't do it."

"Are you a policeman?" Conan used all his strength to open his teeth and claws without any threat: "You can do such a thing!!"

"What's wrong?" Matsuda retorted innocently: "The police are human, and they should also have their own hobbies. Didn't I just shoot two videos? Hehe, if you are so unreasonable, then I will sell these two videos to medical scientists, biologists, and TV stations."

Matsuda threatened so fiercely and made Conan honest. She sat down again, her eyes widened, as if Matsuda was his life and death enemy. When she thought of the shameless guy just now, Conan felt a stream of blood rushing into her mind after he brought him to Tsujimura's bedroom.

When this bastard felt like he was about to die in the most painful time of his life, he not only ignored him, but threw him on the bed casually. He sat on the side with a look of bad taste and took out his cell phone and pressed the evil shooting function. Just like when he was in the toilet just now, when he thought of his pure and young body, his body was as beautiful as a weird person on the bed and was forced to be photographed twice in the toilet. Conan felt that his heart was bleeding constantly.

"You!? When did you discover it?" Conan asked calmly after thinking about it.

"Where is when?" Matsuda saw Conan's tone and smiled calmly: "It's just a little interested. I just checked it briefly. Your physical condition is not too bad, but it looks very painful. So I wanted to study it, but who knew I had discovered something amazing~~"

"You are lying!" After being called "Oh oh" twice by Matsuda, Conan couldn't keep calm: "You bastard have been lying! Just now, I didn't know much about this murder incident! I said that I had too few clues! In fact, you have already seen who the murderer is!"

"Hey? The police department of Meguri seems to be looking for me." Matsuda's eyes fluttered: "You're done, so I'll leave first."

Bastard bastard bastard! Like a fallen girl who didn't ask for alimony, Conan kept jumping and cursing Matsuda who slipped out. But he could only curse a few words in his heart. When he thought of the important evidence related to his chastity and reputation on the unscrupulous uncle's phone, Conan felt dizzy and unable to breathe.

"Hey!" Matsuda was in a good mood just as he walked out of the gate when he saw Mrs. Tsujimura being taken into the police car by Megu. He was about to speed up and chase after him, but was stopped by a sound. Following the sound, Hattori stood against the wall.

"Me?" Matsuda pointed at himself. Although he knew that Hattori must be waiting for him, he still hoped that he was wrong. He just got such an important thing, how could he still feel like playing house with this little kid?

"That's right!" Hattori came over and looked at Matsuda seriously: "When did you see the truth? Since you already know the truth, why don't you tell it out!? Let me embarrass you like a clown!!"

"Who told you that I know the truth?" Matsuda felt so innocent, and then said earnestly: "I just saw the fishing line in your hand and knew that your reasoning was wrong. Little devil, no, young man, listen to people's advice and have a full meal. At that time, you were obviously too obsessed with the victory or defeat, but can a big thing like killing be used to measure the level of the level?"

"You..." Hattori was choked by Matsuda and didn't know what to say.

"Do you know? I'm a policeman." Looking at Hattori's energetic face, Matsuda suddenly felt a little emotional in his heart, and couldn't help but express some of his inner views: "The biggest difference between police and detectives is that we are law enforcement officers. We do not work for material interests such as money. We represent the law, so we must pay attention to evidence. If there is no conclusive evidence, then we must never say who is the murderer."

ps: Only one case has ended in Chapter 4... In the future, some cases will be deleted depending on your mood, leaving only some of the senior officials or touching ones. Speaking of this case, Heiji clearly said it was a toxin for suffocation, so it should be a death of suffocation. After Madam Tsujimura stabbed the poison needle, Heiji probably wouldn't be touched by the body for more than one minute. Will there be poisons that suffocate death within one minute? So that it is difficult for us ignorant people like us to understand. There is no chance to stand up with the protagonist's character, so let's talk about it when the black organization comes out in the future.
Chapter completed!
