The noisy playground, the frightened voices cast a bloody color on the place, and the mournful hissing of police cars made people's hearts tremble.

"Ahh It was the sound of a police car! A skinny little boy with a little freckle on his face exclaimed.

"Wait a minute."

A figure slowly walked out of the tunnel, and when he saw someone coming, the tall and thin boy hurriedly said loudly, "Ah, we didn't come in without buying a ticket!" Angry, the stout boy behind him punched him in the head.

"Ahh Big brother! The girl with her shawl hair and bow on her head pointed to the figure that appeared in the darkness and shouted, "Are you the high school detective?" ”

"Shinichi Kudo." The figure slowly crouched down, revealing a handsome face with a mysterious smile.

Outside the tunnel.

The crowd was noisy, whispering about the terrible event in their earnest voices.

"It's horrible!"

"Looks like the head is missing!"

"Oh my God......"

Next to the covered corpse, Miss Aiko, who had lost her partner, was whimpering under her breath, another female companion was comforting her, and Miss Hitomi Kotomi was standing aside with a blank expression on her face.

"It's just an accident, let's get out." Among the two men in black, the tall blonde man said impatiently to Officer Twilight, who rushed to hear the news.

"No, officer, it's a homicide!" A voice came from the side. "Moreover, the murderer is one of the seven people who were in the same car as the victim!"

For a moment, the audience was silent!

—————————————————————

Charlotte felt that she had walked for a long time, as if the stairs could not be reached to the end, and she had completely lost her sense in the dark, and no matter how sensitive Charlotte felt it, it would not help. He was completely disoriented in the constant hovering, up and down the steps.

"What the hell is this...... Charlotte couldn't help but sigh at her father's strong imagination and design power.

Finally, he felt like he had come to the end.

In front is a door.

Approaching, Charlotte gently pushed, and the heavy iron door actually opened.

Charlotte was not surprised, since his father had put so much effort into building such a secret room, he was sure that the person who came in must be himself, so since he had found this place, there would definitely not be such an oolong situation as not being able to enter the door.

Pushing the door in, a rotten aura mixed with dust rushed to her face, making Charlotte frown.

"It seems that no one has been here for a long time, is it true that you really ...... father?"

Shaking her head, no longer thinking about going on, Charlotte dodged into the room, not forgetting to cover the iron door with her hand. "Click!" With a bang, under Xia Luo's stunned gaze, the seven-centimeter-thick, almost all-steel gate was gorgeously locked!

"I'll rely on ......" Charlotte couldn't help but have a headache, and then shook her head, forget it, father, he won't trap himself here, right? Thinking like this, he casually touched the switch on the wall.

"Click" sounded softly, and the room was bright.

The room was small, but bloated with a large bookshelf, a computer, a small desk, and a soft chair.

Charlotte dusted off and sat down in a soft chair.

"It's really Shinichi, where did you run away again!" Xiaolan in the crowd saw Shinichi and hurriedly ran over and grabbed his sleeve.

"Really? Kudo-san?! Officer Twilight was taken aback and hurriedly asked.

Suddenly, a burst of shouts erupted in the crowd: "Kudo Shinichi! It's actually a famous high school detective! ”

"The savior of the Japanese police!"

"Kudo?" A hint of murderous intent flashed in the eyes of the man in black.

"In other words, you and Ran are excluded in the first place," Officer Twilight mused, "because everyone is protected by a protective fence, the only one who can kill the victim is the lady sitting next to him." ”

"Hey! Hurry up, okay! The blonde man in black said coldly, "I don't have time to play any reasoning games with you!" ”

Shinichi turned around, and when he saw the eyes of the man in black, he couldn't help but be shocked.

"This guy has a cold glint in his eyes, and he looks like he doesn't care if he kills a lot of people! This guy ...... Who the hell is it? Shinichi thought in his heart, and suddenly, Shinichi felt a shock in his heart, black!

"Kudo, I can only tell you one word, this is one sentence that you must always remember. Watch out for black! ”

Xia Luo's cold voice seemed to still echo in his ears, "Could it be that the black refers to these two people?" Shinichi couldn't help but wonder.

"Officer, a knife was found in this lady's bag!"

A police officer's voice interrupted Shinichi's train of thought again, Shinichi shook his head, now is not the time to think about this, the most important thing is to solve this case! His eyes hardened, and he stood up and walked towards the scene.

"I didn't even know I had this in my bag!" Aiko looked at her bag and cried out in horror.

"Aiko!" Hitomi exclaimed, "I thought you had a good relationship with Kishida...... How would you? ”

"Nope! It's not me! Aiko pleaded weakly.

"Okay, the prisoner is the woman." The blond-haired man in black said impatiently, "This time we can go, right?" ”

"Good!" Officer Twilight shouted, "Take this young lady back as a suspect!" ”

"Wait a minute, Officer Twilight. The prisoner was not this young lady. ”

A calm voice came from behind him, and Officer Twilight turned around in surprise, "So, who do you say the prisoner is?" ”

Shinichi didn't speak, turned around and walked behind Aiko, and everyone looked at this Heisei era Sherlock Holmes with strange eyes.

"There is usually only one truth." Shinichi said lightly, then raised his hand and pointed at a person, "Murderer, it's you!" ”

"Hitomi-chan!"

Everyone was stunned, and everyone looked at Shinichi and Hitomi. "What are you talking about! The knife is in Aiko's bag! Miss Hitomi said in surprise, but her voice trembled a little.

"There is no way to cut off a human head with a knife like this." Shinichi said solemnly, "It's even more impossible with a woman's strength!" You put the knife in Miss Aiko's purse in advance to blame her. ”

"But she's sitting at the front of the roller coaster, doesn't that seem likely?" Officer Twilight questioned.

"If you take advantage of the speed of a roller coaster, add a piano wire or a steel collar." Shinichi's tone remained unchanged, still keeping his eyes on Miss Hitomi. Xiao Hitomi's face couldn't help but change.

Seeing her reaction, Shinichi was even more sure of his guess, "I think it's better for us to test it ourselves." Officer Twilight. ”

"First of all, before pulling the guard bar, clip something like a leather bag behind your back." After everyone was seated, Shin began his experiments. "When the leather bag on the back is taken away, creating a gap, it is easy to break free from the inside." Shinichi took off the protective bar, "Next, take out the ferrule that was prepared in advance to tie it with a hook attached." Stick your foot on the protective bar, stretch your body back, and put the stalk around the victim's neck. Of course, it's all in a pitch-black tunnel. A new rope with an iron hook is put around Twilight's neck. Everything is flexible.

"When everything is done, throw the hooked end onto the rails, so that with the speed and momentum of the speeding car, you can cut off the head!" Shinichi said this, and his warm blue pupils were fixed on the little pupil. "Because you've done gymnastics before, you can easily do that even on a roller coaster."

"No kidding!" Hitomi looked a little crazy, "All this is just your speculation!" Can you come up with proof! ”

Shinichi's eyes sharpened, and his body faintly exuded a chill similar to Charlotte's. "Where's your necklace?" Shinichi asked lightly.

"Ahh Hitomi was speechless.

"It's the pearl necklace you wore before you boarded the roller coaster!" As he spoke, Shinichi reached into his pocket and pulled out a bag containing pearl threads with iron hooks, and several pearls in it still shone with crystal light. "Isn't that it?"

"And one more thing, that tear." Shinichi said slowly, "You already knew that the victim was going to die, so you shed a tear for him." ”

"You still have tears in your eyes, and if you weren't on a roller coaster, the tears wouldn't flow to either side."

Listening to Shinichi's words, tears gradually poured out of Kotomi's eyes, and finally she slowly knelt on the ground and cried bitterly.

"It's all his fault!" Hitomi whimpered, "It's all because he abandoned me!" ”

"Hitomi Kotomi...... Have you ever dated Mr. Kishida? Her female companion Reiko said in surprise.

"yes!" Hitomi's face was slightly hideous, "When I was in college, I didn't know Aiko and Reiko yet!" At this, she covered her face again and cried bitterly, "That's why I'm ...... At the place of the first date, use him ...... Give me a necklace to end his life ......"

All the women present sobbed, as if sympathizing with Hitomi-chan's painful feelings. At the same time, it may also be sad for this deformed love.
