"Is this the needle that killed the Ikemura diplomat? Bring it back to the forensics department for testing! Yuichi, who was looking for evidence around the body of the Ikemura diplomat, soon discovered the silver needle that Conan and Heiji Hattori had found earlier.

After waving his hand to the forensic staff behind him, Yuichi, who carefully pinched the poison needle and put it in a small plastic bag, continued to compare with the surroundings.

Yuichi pretended to be happy and didn't care, but the Twilight Police Department, who was nominally the person in charge of this operation, couldn't ignore it, and after taking Yuichi's mess and Hattori Heiji, who still hadn't reacted from the blow just now, explained a few words in embarrassment, he couldn't help but stand next to Yuyi and secretly muttered, "That's the son of the chief of the Osaka Prefectural Police, is it really good for you to offend him like this?" If there is something to ask someone else for in the future. How did you open this mouth? Brother Youyi! You are so reckless! ”

"Oh? Have it? How do I not think? It's just a kid who doesn't know the height of the sky if he has a little ability! Compared to my brother who is not as good as me, what are you fighting to pretend to beep in front of me? Meow! I'll step on him! Stampeing him to death! Anyway, my brother is also his good friend after that! What if he is dissatisfied with me? Muttering, after saying something that the Twilight Police Department didn't understand, Youyi waved his hand and asked the Twilight Police Department, which was becoming more and more Xianglin's demeanor.

After turning his head and glancing at Hattori Heiji, who was looking at him with strange eyes, he felt that he couldn't lose face in front of the Kansai people, and then the Twilight Police Department coughed in embarrassment and skillfully gave Yuichi a shot.

"Are all the windows locked from the inside? In this case, there is almost no possibility for outsiders to break through the window, and those who can enter here can only enter through the entrance of the door, Mrs. Ikemura! How many keys do you have to this room in your house? Where to put them? Or in whose hands? ”

Looking at the Twilight Police Department, who finally understood that he could no longer be a background wall under his own training, and began to take the initiative to cooperate with the investigation work of himself, Yuichi, who listened to the confessions of these suspects in the house while searching for physical evidence, couldn't help but nod his head in approval with relief.

"Nope! There are only two keys to this room! One is in my hand, and the other is in my own hand! ”

"Oh? Only two? Then since Mrs. Ikemura's is still in her hands, so if the gangsters want to commit murder, they can only steal the one in the hands of the Ikemura diplomat. If you calculate it this way! Looking at the key that Mrs. Ikemura took out as she spoke, the Twilight Police Department, whose mind was not completely blank, immediately thought of an important clue that this case could happen.

It's a pity that he hasn't been excited about the big news he found here, and that face Yuichi coldly interrupted his fantasy of being a detective.

"Dusk Police! You're thinking too much! Diplomat Ikemura's key was not stolen! It's time to stay quietly in his own pocket! Look at this! ”

"What? How so? Looking at the key that fell out of the pocket of the diplomat in Ikemura with a loud bang, the Twilight Police Department on the side couldn't help but be shocked.

"Interesting! It's actually a case of murder in a closed room! This one is so good to my taste! Yuichi Kudo! Since the main purpose of this visit, Shinichi Kudo, has not been found, so let's replace him with you! Bet on the reputation of the detective, and now I officially inform you! I'm going to challenge you secondarily! ”

"Oh? Is it? Welcome to the battle! But for now, please don't bother the police to solve the case, okay? As the son of the chief of the Osaka Prefectural Police Department, don't you know any common sense? ”

"Common sense? Phew! In Osaka, I also drive a police car to travel around! After complaining angrily, Hattori Heiji, who knew that he was not welcome here, had already lifted the table and roared in his heart, but he was still a little sensible, and he finally stood in place, his face changed for a long time, and then he stood aside with interest, watching Yuichi, who became the protagonist of this room, continue to pretend.

"All of you who were in this room at the time of the crime introduce yourselves one by one! And tell me what you were each doing in the time leading up to Uncle Kogoro Mori coming here! After all, it seems that you are the most suspicious now! Ignoring Hattori's eyes that could stare at the dead, and after discovering that there was no conclusive evidence around the Ikemura diplomat for the time being, Yuichi, who was wandering around the room and observing the furnishings around the death scene, suddenly wanted to ask Fumio Koike, the housekeeper who was called in by the Twilight Police Department.

"Me? I had been sitting at the door chatting with my neighbor before Mr. Kogoro Mori came here, and you can go and ask that neighbor now! He can testify to me! ”

"Oh? Is it? That's good! ”

"In that case, what are the others doing besides Mrs. Ikemura, who went to find Uncle Kogoro Mori? This is the son of a diplomat at Ikemura, right? And this beautiful woman next to you! Come on, come on! Don't be shy and hide in the doorway! Come in and talk! Where were you doing before Uncle Kogoro Mori came here? ”

"Sachiko and I went to my father's room, but the door was locked! And no one agreed! So we went downstairs quickly! ”

"I see? What about Mr. Toshimitsu Ikemura? What did you do in the afternoon? ”

"Me? I'm here to see them! I didn't expect Ah Xun to stay in the study and refuse to come out! Gongjiang is not at home again! I had no choice but to go to the old TV in the living room next door to the study. ”

"I see? The alibi of all of you doesn't seem convincing! In that case, you can't be removed from the list of suspects! After listening to the testimonies of several people, Yuichi, who had already talked to Mori Kogoro about Mrs. Ikemura, was more interested in this confusing case, so he wouldn't admit that he had taken the challenge of the African friend imp just now seriously, and before Hattori Heiji solved the case, as a representative of the Tokyo Metropolitan Police Department, Yuichi had to reason out the case.

"Huh? Do you like CDs very much? ”

"Yes! The old man likes to listen to classical music, so he has a lot of collections! Hey, hey, hey! Officer Kudo, can my suspicion be ruled out? My alibi is witnessed! ”

"No! After verifying with the neighbor you provided, we will be able to make a judgment on your alibi! ”

"Huh? Classical music? If I'm not mistaken, there was an opera in the house when we came, right? That stinky cop doesn't have this information, it's a clue to take the lead! Hopefully something can be found out! ”

"Brother Yuichi! I'll tell you......" Just when Heiji Hattori thought that his chance to turn the tables came, a somewhat immature child's voice completely shattered his illusions.

"The Maori detective's imp is too cheaty, isn't it? Do you have to hand over every penny you pick up on the road to the police uncle? You can sue for such important evidence? I just thought you were different from others! It turned out to be a bear kid too! "I didn't know who I had offended after analyzing Xiaolan at the Maori Detective Agency and determining that Kudo Shinichi was next to Xiaolan, and he completely regarded Conan as a bear child.

But will Conan be a bear child? Hehe! He is Kudo Shinichi who will be avenged, and this revenge must be avenged!
