"Did you really come in? Is that how the murderer committed his crimes? The Twilight Police Department, who was invited by Hattori Heiji to be the victim of the case, screamed in disbelief as he looked at the key that was pulled back from the door by the fishing line and went down the table into his pants pocket.

"That's right! That's how the murderer did it! So the prisoner is Grandpa Ikemura, because he ......"

"Yes! Skynet is magnificent but not leaky! That's what I did! Take me away! ”

"Oh? The old man Ikemura actually took the initiative to confess his guilt? In that case, then ......"

"Wait a minute! Twilight Police Department! It's just a kid who is ignorant and reasoning nonsense! Can't be taken seriously! Now that this little ghost beep is finished, let's start the official case! ”

"What? Actually say I'm XJB reasoning? Is it tolerable or unbearable! Yuichi Kudo, don't talk about what you don't have! Say I'm reasoning nonsense, get your evidence out! Originally, he completed his reasoning, and the murderer also surrendered to the law by himself, and everyone around had their eyes shining with admiration, and Hattori Heiji, who was enjoying the pleasure of successfully solving the case, suddenly roared angrily.

"Proof? Of course! It's just that my cousin, a stupid idiot, has a good saying, reasoning is not high or low, winning or losing, because there is only one truth of the matter! Hattori Heiji you remember! If you lose this time, you will lose because you are so competitive that you will be blinded by your own heart! Give me a good look at this picture! In the face of Heiji Hattori, who has been completely provoked and blown up, Yuichi, who feels that he has been pretending to be a beep to the G spot, finally threw out evidence that he said that Mori Kogoro's questioning had something to do with this case.

"What is this?"

"The photo that fell out of a CD when I just flipped through the CD shelf should be a photo of Mr. Isao Ikemura and Mrs. Ikemura when I was young!"

"But what does this have to do with this case?" Hattori Heiji, who was deep in thought, didn't ask a question yet, and the Twilight Police Department on the side immediately asked impatiently.

"Of course it does! Don't you think that Mrs. Ikemura when she was young resembles someone here? I just called and found something interesting, such as a diplomat named Kenji Yamashiro twenty years ago! Mrs. Ikemura, do you have any impressions? ”

"Hehe, of course there is! I will never forget him for the rest of my life! He's my husband after all! ”

"What? Kenji Yamashiro is your husband? That's impossible! How is this possible! Hearing Mrs. Ikemura's sudden revelation of her love history, the others didn't react, but Sachiko Katsuragi, who had been standing silently next to Ikemura Takazen, suddenly got hit and ran out from behind Kizen with a roar, staring at Mrs. Ikemura in disbelief.

"Like! It's so similar! Is that so? Sure enough, I was carried away by the victory! Although I haven't seen Kudo Shinichi himself, the person who can say such things must not be a simple character! This time I was reckless! Just when the Twilight Police Department and Mori Kogoro watched the annual drama of family ethics that suddenly unfolded and didn't know what to do, Heiji Hattori, who had just been dumped by Yuichi and didn't speak, finally sighed and spoke again to break the deadlock.

"Huh? Little brother Hattori? What do you understand? Why do I still not understand? Hearing Hattori Heiji say this, the Twilight Police Department finally came back to his senses reluctantly from his stunned state, and asked with a blank face.

"Kenji Yamashiro should be the father of this Miss Sachiko Katsuragi, which means ......"

"Sachiko Katsuragi is the daughter of Kenji Yamashiro and me, and my husband Kenji Yamashiro was falsely accused of corruption and bribery twenty years ago and unfortunately went to prison! Five years later, he suddenly died in prison! At that time, Sachiko was also taken away by relatives of the Yamashiro family, and I suddenly fell into a complete collapse and confusion, and it was at this time that Isao Ikemura came to my side and captured my heart that I needed to rely on by helping my husband Kenji Yamashiro deal with things. In this way, I spent so many years with him in a daze, and it wasn't until a few days ago when Takazen put Sachiko's photo in front of the two of us that Ikeda Xun, who confided the truth at that time, made me understand who was the murderer who framed my husband in prison and finally died in vain! I've been living with my husband's killer for so many years! I will never allow Sachiko to live like this! So I'm going to make a break to all of this! And then I laid it all out with my own hands to get rid of that bastard! Judging by Dad's performance just now, you also know that Ikemura Xun did this kind of thing back then, right? Just when the Twilight Police Department was a little confused, Mrs. Ikemura, who was silent on the side, suddenly smiled and began to speak.

"Yes! It was I who hesitated for a moment to watch Ah Xun make such a mistake! But Kenji Yamashiro is dead, and I can't regret it! So I can only compensate for my guilt in my concern for you, but I didn't expect you to forgive us in the end! That's fine, let me, the old man, make up for you at the end, I hope you can let go of the past from here on and start over! It's a pity that it was recognized! Looks like this old bone can't help you anymore! In the face of Mrs. Ikemura's inquiry, the old man Ikemura, who had already confessed his guilt, was no longer silent, and sighed.

"This, this, this...... But since Mrs. Ikemura has the key, why does she have such a complicated design? ”

"Of course, she framed the old man to take the blame for her, and she has no plans to bury Ikemura Xun! This is something I found in other homes, and it should have Mrs. Ikemura's fingerprints on it! Hearing the somewhat depressed inquiry from the Twilight Police Department, Yuichi took out a ball of fishing line and looked at Hattori Heiji and laughed.

"In addition to the Japanese room, other families also have this thing?"

"Yes! So if we want proof, we can check the same keychain in Mrs. Ikemura's pocket as Ikemura's, and if my reasoning is correct, there must be something we want in that ornament that can also be opened! ”

"Shinichi? You're back? You're a bastard who has been around me and watching my anxious jokes, haven't you? ”

"Xiaolan! I didn't! I just ......"

"Why do you talk so much nonsense? Kiss her directly! A sucker! Our Kudo family's face has been disgraced by you! Go and have a kiss! Don't bother us, adults! After taking several balls of fishing line from other rooms from Conan's hand, Yui pushed Shinichi, who was still a little shaky, to Xiaolan's side, and stretched out his hand in front of Mrs. Ikemura.

"Give me the key, right? Take advantage of Uncle Maori and their followers into the room, take advantage of the murderer's blind spot that the murderer will not invite the detective home to see his own murder, and use the hidden poison needle to kill the diplomat who was stunned by you in advance! ”

"No need! I admit that I killed him, and the physical evidence is exactly what Officer Kudo thought, I have this in my keychain! ”

Looking at the needle-shaped traces in the opened ornament, everyone suddenly understood who the murderer was.
