"Who the hell is this little ghost?" Matsuda reached out and pushed Hattori's head, keeping the hot-blooded young man away from him. Although this was Hattori's debut, Matsuda was more interested in the upcoming Shinichi Kudo.

"His name is Heiji Hattori, and he is a crazy boy who calls himself a detective. Kogoro saw that Hattori was ignored by Matsuda, and he felt happy from the heart.

"Heiji Hattori?" Twilight muttered the name twice: "Ah! It turned out to be you!Osaka Police Headquarters Headquarters Chief Hattori Heizou's son who is really in high school!?"

"The son of the head of the Osaka Police Headquarters!?" Matsuda scratched his cheeks: "Aha~~ It turned out to be the second generation of officials, and the little ghost named Kudo was the rich second generation." It seems that only this kind of rich son who does not worry about food and clothing will play some reasoning game. ”

"Reasoning is not a game!!" Conan and Hattori are in step with each other, working together to defeat all evil class enemies. After the two of them finished talking together, they looked at each other in surprise.

Seeing that Matsuda had a tendency to deviate from arguing with the little detectives, Twilight stood behind Matsuda and coughed deeply. So that Matsuda, who was about to have a further in-depth discussion with Hattori Conan, suddenly understood his position.

"I just looked around in this room, ahem. Matsuda became very serious: "All the windows are locked from the inside. The only exit was the door, and the killer was most likely the one who had access to the key to this room in this home. ”

Well. Twilight nodded, Brother Matsuda was really reliable at a critical time, it was his temperament. Sighing secretly, Twilight asked the deceased's wife, Tsujimura Koe, "Mrs. Tsujimura, how many keys are there to this room?"

Tsujimura Koe was the one who invited Kogoro to their home from the Maori Detective Agency and was the first to discover her husband's body. Mrs. Tsujimura heard Twilight's question, and as she put her hand into her bag, she said, "There are two keys to the study, one of which is with me. Mrs. Tsujimura took out the key and continued, "The other one is on my husband. ”

"Your husband?" "Twilight couldn't believe it.

"That's right. Mrs. Tsujimura said, "My husband usually keeps the keys in his pants pocket. ”

Twilight walked up to the dead man with a solemn face and reached into his pants. When the deceased's pants pocket was turned out, a key slipped out of his inner pocket.

"How is that possible!" Twilight and Hattori Conan were shocked, as if they had seen something they shouldn't see. Well, or rather, that key shouldn't have been there in the first place.

"What's wrong?" Kogoro, who was a hindsight, didn't understand the seriousness of the matter yet.

"Don't you understand the situation?" Hattori said, "The door was locked when we entered, so the murderer didn't leave until the door was locked." There are only two keys to this room, one in the hands of Mrs. Tsujimura, who came in with us, and one in the double pocket of Mr. Tsujimura's pants, who was killed. In this way, a closed room is formed, which is a closed room homicide. ”

"Murder in a closed room!?" was taken aback by the people present. Matsuda crouched down and picked up the key that had fallen from the deceased, and looked at it carefully, revealing a mysterious smile.

As long as there is someone in the family who has access to these two keys, it is not too difficult to secretly match one. This kind of key is not a special key that is too complicated to copy, why does no one think about it?

Matsuda was puzzled, although he vaguely remembered that the incident in the animation was characterized as a murder in a closed room, but when he saw this key, he couldn't help but guess. Is it the family members of these diplomats present, the second generation of officials, the second generation of rich detectives, or the police department are all in the big class, and they don't know about these people who are going to fight and know about it, or

Or is it that the country of Japan is too rich in the animation, so there are no handicraft skills and skills in the Celestial Empire that are crawling at the grassroots level and taking the door and picking locks as their profession? Matsuda, who was suspicious and suspicious, didn't think about it, and the biggest surprise was that he, an excellent policeman who should have died three years ago, actually lived to the time of Edogawa Conan.

Matsuda, who was holding the key and smiling incomprehensibly, didn't notice that everyone in the room was looking at him, thinking that he had seen some clues. The people who were full of expectations did not realize that the highly anticipated Officer Matsuda was outside the wandering object, and his thoughts had flown to the heavens and the earth.

"What are you guys doing!" Hattori watched for a long time, and when he saw that Matsuda didn't react, he felt like a fool, and said to Twilight in annoyance: "The time of the crime is determined to be between half past three and four o'clock, and now we should find out the alibi of the person who may have committed the crime during this time period as soon as possible, this is the most important thing!"

"That's right. Twilight smiled, then walked up to Matsuda, grabbed the key in Matsuda's hand, and lowered his head: "Brother Matsuda, hurry up and find out the truth, and suppress this hairy boy! ”

Matsuda keenly grasped the main point and smiled ambiguously at Twilight.

Heh, huh. Twilight wiped the sweat from her forehead, and she was no longer as strong as before. Matsuda, you bastard! It's not all your fault, every time this kind of murder has been done by Kudo or Maori brothers in the past. It's gone by turning a blind eye to the above, and now that you are a master of reasoning, and let the media say that we are incompetent, letting those detectives be in the limelight will naturally make the top unhappy.

Because of the murder of a popular idol last Christmas, although Kudo Shinichi who solved the case behind it was hidden from the public, Twilight naturally didn't dare to hide it when he made a report.

"How do you do this police department! Let a high school imp dictate your territory!" The thought of being scolded by Matsumoto Police, Twilight gritted his teeth for a while. Matsuda, you idiot, dared to slip away on Christmas Day, don't want any more vacations in the future!!

"Hey, police department. Matsuda gently resisted Twilight and woke him up, and said very sneakily, "Why don't we go have a drink tonight?" ”

"Okay. Twilight agreed gloomily. Matsuda, who didn't know what a precious thing he had lost after the road, thought he had earned it, and rushed to the scene full of energy, scanning for all the clues that could be used.

"Now I'll ask a few of you to tell me what you're doing between 3:30 and 4 o'clock. Matsuda took a small notebook and approached the butler Fumio Koike: "Then let's start with the butler Mr. Koike, please tell me in detail where you were and what you were doing." ”

"I was chatting with my neighbors at the gate from half past three to four. Koike received the spiritual oppression of Matsuda, whose eyes were glowing green, and said very carefully.

"Uh-huh. Matsuda nodded with satisfaction: "It seems that there are witnesses, then" Matsuda turned his head and aimed at the deceased's son Takazen Tsujimura and his fiancée Sachiko Katsuragi.

Takazen Tsujimura hugged his frightened fiancée Katsuragi and replied to Matsuda, "We arrived not long before my mother came back, and we met Mr. Koike at the door. When we entered the house, we went to the study to look for my father, but the study was locked, and there was no response to knocking on the door, so we came down from the second floor, and then my mother came back. ”

"And what about the old man?" Matsuda asked the deceased's father after the record was recorded.

"I came at about two o'clock, Ah Dong was locked in the study, Gongjiang went out again, and I watched TV for a while in the living room next door to the study. The father of the deceased, Toshimitsu Tsujimura, replied.

"What about Mrs. Tsujimura, when did she leave the house?" Matsuda asked the last suspect.

"I left the house before one o'clock. Tsujimura replied calmly.

Seeing that Matsuda was rarely so energetic, Twilight looked around easily, and locked her eyes to the cabinet full of CDs on the wall: "There are so many CDs here." ”

"Yes, our lord likes to listen to classical music the most. Butler Koike explained on the side.

Classical music? Conan keenly grasped something. When we first came in, we were playing opera.

Conan finally showed his head, but Matsuda was targeted. Seeing Conan, who was about to fall, Matsuda's eyes lit up. Why did you forget about serious things? For now, it's better to keep an eye on Conan, a little ghost. Well, I'm actually here for work, after all, the clues found by this little ghost are the key to solving the case.

Completely unaware of the road, Conan, who is targeted by an unscrupulous policeman for a very legitimate reason but for a very improper purpose, begins his difficult journey to solve the case.

Well, I swear this is the last time I can expect anything from Matsuda's bastard. Twilight, who has nothing to do, sees Matsuda staring at Conan affectionately, and immediately labels him as impossible. Secretly grabbed Kogoro, and whispered, "Brother Maori, I can only rely on you this time, how is it?

The prisoner, the prisoner is Conan, who figured out the truth, was finally knocked down by the disease, and he was about to fall to the ground with a top-heavy head. At this time, a figure felt caught him in time.

In the next second, people saw clearly that the figure turned out to be Matsuda. Matsuda, it turns out that he saw that Conan's body was wrong. Twilight was ashamed of her guess about Matsuda. However, he didn't notice the smile on the corner of Matsuda's mouth, otherwise he wouldn't have noticed it, in fact, he misunderstood Matsuda again.

Transformed, about to transform. One of the two most incredible events of the detective is about to happen! Matsuda excitedly grabbed Conan, who was about to faint.

Of course, the two incredible events of the so-called detective are Matsuda's own definition, Edogawa Conan transformed into Kudo Shinichi, and the other is Kudo Shinichi's gorgeous transformation into Edogawa Conan.
