Shinichi woke up not long after Takushi Yamamoto left, opened his eyes, felt cold, got up and looked at it, blushed instantly, took some pieces of clothes to cover the vital point, and got out of bed to find some clothes.

As soon as he got out of bed, he almost knelt down, the sadness of the egg made him a little frightened, fortunately, his reasoning ability was not covered, and after checking the situation in the room, he roughly understood the specific situation, and was a little embarrassed and happy at the same time, although the process was a little unexpected, but the ending was still very gratifying...

"Now it's back now, Xiaolan, you wait for me!" Shinichi thought to himself, quickly put on the clothes he found temporarily from the room, and went out to find Xiaolan and tell her that he loved her...

Following the route taken by Takushi Yamamoto, passing by the scene of the crime, at this time Hattori had just made a demonstration and began to talk about his reasoning, Shinichi stopped when he heard it, firmly believing that there is only one truth, truth and justice, he decided to solve this case first and then go to Xiaolan...

In the room where the crime occurred, Heiji Hattori pointed out that the victim's father, Toshimitsu Ikemura, was the murderer, and when Toshimitsu Ikemura also admitted it, Shinichi pushed open the door and walked in and said, "No, he's not the murderer..."

Hattori Heiji followed the sound, a man walked in from the door, listening to the exclamations of the people next to him, he confirmed the identity of the other party, the opponent he was looking for in Tokyo today - Kudo Shinichi.

Hattori Heiji felt that the people around him were shaken by his reasoning because of Kudo Shinichi's sentence, and he was very annoyed by this, and said defiantly: "Hey! You kid came out and got a mistake... Could it be that there is some flaw in my reasoning? Then you can tell me! Kudo! ”

"That's right, I'm just going to tell you that your reasoning just now is just on paper..."Kudo Shinichi walked up to Hattori Heiji and said, "And yes, it's 100% impossible to have a modus operandi!" ”

"You, what do you say!" Hattori was very annoyed when he heard this, and he felt the urge to hit someone. Seeing this, Twilight quickly interjected and relieved, "Hey! Kudo, shall I make a mistake? The secret room tricks that Hattori deduced are really impeccable! I did it myself just now! ”

Then Twilight thought that Kudo Shinrai didn't know Hattori's reasoning, so she explained.

"First, take a needle and tie the fishing line, then attach the untied end to the key ring with a belt, and let the end with the needle come out of the pocket of your pants..."

Then, pull the two ends of the fishing line out of the room, lock the door with the key, and pull firmly on the end with the needle tied to it, and the key will automatically run back into the pocket.

"Finally, pull hard, let the fishing line pull out the tape, and roll the fishing line, so that even the evidence can be destroyed The ingenious secret room trick has been successfully completed!"

Kudo Shinichi listened quietly to Twilight's introduction, until the other party finished speaking, and he said lightly, "Is the key really in the pocket?" ”

"Ahh The key did run into the pocket of the victim's pants......"

"Is this still to be asked? I took a needle and threaded the fishing line through the pocket of my pants. On the side, Hattori was extremely annoyed by the questioning, and directly touched the pants pocket of Twilight and said, "If you don't believe it, just look at this!" Look at the mezzanine of these pants... How could it be! ”

As Hattori spoke, the key fell out of his trouser pocket, and the battered Hattori muttered in disbelief with the key, "Impossible!" Impossible! I obviously have a fishing line through the mezzanine pocket! How could the keys not be in the pocket? ”

"The point is that when the key goes in, the police department is sitting." Shinichi looked at Hattori with a look of disbelief and explained, "Because when you're sitting." will press into the pocket. The space also narrows, so the fishing line is ripped out of the tape before the key is in the mezzanine pocket! What's more, the victim's body is as fat as the police department, so the key can't get through the pocket at all! ”

"But despite this, there is still a possibility to go in! At least once in ten! Hattori struggled, he couldn't tolerate being wrong.

"No matter how many times you try, it's the same result." Shinichi denied, "Think about it, how it was placed when it was found in the mezzanine pocket?" ”

"Directions?" Hattori was stunned for a moment, thought back in a daze, and muttered, "The direction of the key?" Hattori shivered violently and exclaimed, "That's the key......"

"Yes, the key was folded!" Shinichi said: "Even if the key really runs into the double pocket, it should only be the key ring to go in, and the key can't get in, because the double pocket is too narrow and not long enough!" It is also impossible to fold the key and the keyring into a V-shape, but the key and keyring went in well, that is, the murderer put the key in the double pocket of the deceased at the beginning. ”

"This, is this possible?" Hattori Heiji was shocked and said, "Kudo, can this be done?" Also, what about the fishing line I just found from the Japanese-style room. ”

Shinichi glanced down at the fishing line and said lightly, "In fact, it is precisely because of these fishing lines that I can be sure that your reasoning is wrong." ”

"This ......"

Without waiting for Hattori to ask, Shinichi showed the white object in his hand to everyone.

Seeing clearly what the item Shinichi showed to everyone was, everyone screamed in shock.

"This ...... These are fishing lines??? ”

"Yes," said Xin, nodding his head, "I have just walked around the house and found it, to be exact, it must have been a trap set by the murderer, in order to blame the old gentleman." ”

"Huh?" Hattori Heiji suddenly understood, and shouted: "The real murderer has long planned to frame the old man, so you found the fishing line in many places, in this way, as long as the case is reported, no matter where the old man is, as long as the search and the fishing line is found, this frame will be established." ”

"Exactly!" New nodded a little and breathed a sigh of relief.

Therefore, she hates reasoning, and this interlocking explanation is too annoying.

"But," Hattori Heiji shouted again, "the old gentleman just admitted that he killed someone, what's going on?" ”

"That's because the old gentleman deliberately jumped into this trap! I don't know why. Speaking of this, Shinichi frowned slightly.

"But, in that case, isn't this study a perfect secret room? How did the murderer kill people? Do you want to say that the victim died by suicide? Heiji Hattori continued to ask.

"Nope! The victim didn't commit suicide......," Shinichi said with conviction...
