When Conan and the others arrived at the door of the Kaido Building leading to the basement, they found that Takato and Ashbara had already been there, while Sonoko Suzuki and Yuri Noguchi had already been rescued.

"Garden!"

Seeing that Suzuki's garden was safe and sound, Xiaolan couldn't help but step forward and couldn't help hugging the garden tightly.

"Little Orchid......"

Facing Xiaolan, Yuanzi couldn't help but burst into tears and hugged Xiaolan.

"It's okay."

Xiaolan gently patted the back of the garden as if she were comforting the child's mother.

"Miss!"

When Kamoshida saw Yuri Noguchi on the side, he couldn't help but say excitedly.

In this regard, looking at the scene in front of them, everyone's mood finally breathed a sigh of relief, and Conan walked to Gao Yuan's side curiously and asked in a low voice:

"Where did you go before, Mr. Wise? How did you find this place? ”

Looking at the hostages who had been rescued at this moment, as well as the policemen present, Gao Yuan couldn't help but say:

"Well, now that the hostages have been freed, it's time to unravel the truth behind what appears to be a kidnapping."

Hearing this, everyone present was surprised.

"Wise brother, are you telling the truth?"

Officer Twilight asked.

"That's right. I figured out the identity of the kidnappers and the way the diamond disappeared. ”

Takato said, looking around at the people present, and then his gaze finally fixed on Noguchi Yuri's body, revealing a smile.

"Really, you know how the kidnappers took the diamonds!"

When Kogoro heard Takato say this, he immediately asked with great interest.

"On this point, we might as well go to the road that Miss Miki once walked along with the box."

Takato proposed.

"Huh? Why don't you go and have a look? ”

Officer Twilight asked.

"Yes, that way, you should be able to detect the kidnappers' tactics. Also, please call the patrol officer who had contact with Miss Miki at the time. ”

Gao Yuan nodded and said.

"Is that the patrolman who picked up the box?"

Officer Twilight confirmed to Takato.

"Yes, that's him."

Gao Yuan said.

"I see, there was a police station near the place where the patrol officer appeared at the time, and I can probably assume that he was working there."

Officer Twilight nodded, thinking.

"Hey! Brat! Wait a minute! Didn't you say that you were trying to unravel how the kidnappers could get the diamonds floating in the air from our watch? What does this have to do with the path that Miss Miki has taken? ”

Kogoro asked, puzzled.

In this regard, Gao Yuan smiled faintly:

"When everyone passes, they will know that the kidnappers' ruse to take the diamonds has already set a trap from there."

Looking at Gao Yuan's expression, Officer Twilight nodded deeply, Xiaolan, Yuanzi and the others were also convinced of Gao Yuan's words, and Conan suddenly felt enlightened after listening to Gao Yuan's prompt just now.

Only Kogoro complained indignantly, dragging behind everyone, but halfway through, Takagi Wataru was nowhere to be found.

……

"At that time, in order not to be discovered by the kidnappers, we deliberately separated a distance from Miss Miki when we were following, about twenty or thirty meters."

Officer Twilight said as he looked back at the driveway.

"That's right, the kidnappers just took advantage of the dead end within twenty or thirty meters."

Gao Yuan explained.

"Dead end? What the hell do you mean there's a dead end? ”

Grain

Kogoro asked loudly after a distance from everyone.

"It's just around the corner from that building."

Gao Yuan pointed to a ten-story building in front of the road and said:

"When Miss Miki turned the corner from that building, you who were far behind couldn't see Miss Miki's figure for a moment."

Gao Yuan said, suddenly picking up his pace and disappearing around the corner of the building.

"Really!"

Seeing this, Xiaolan suddenly remembered the previous situation and said in surprise.

"However, at that time, I quickly slammed on the accelerator and chased after me, and at most Miss Miki disappeared in front of me for a few seconds...... And, where was Mr. Wise at the time? Why do you know this? ”

Miwako chased after him quickly, turned around the corner, and immediately asked when she saw Takato.

"A few seconds will be enough."

Gao Yuan smiled confidently and said, "Because I was in front of you at the time, and I clearly saw the whole process." ”

As he spoke, Takato walked over to the fire hydrant hanging on the wall of the building and pressed the side of the four-corner box containing the fire hydrant hard.

With Gao Yuan's movements, only a "click" was heard, and some kind of device jumped out of the inside of the box-

"See. The kidnapper put the box in from the left, and then pressed out the fake box that had been placed inside from the right side, and the box automatically bounced to the ground, and with Miss Miki's acting skills of falling, the replacement of the box was completed. ”

"This ......"

Looking at this scene, Officer Twilight was speechless in surprise—

"Wait a minute! What you just said was Miss Miki's acting skills......"

Kogoro looked at Takato's movements in surprise and said in surprise.

"There's nothing wrong with that. The kidnapper I'm talking about is Miss Miki herself! ”

Gao Yuan said, and from the mechanism on the right side of the fire hydrant, he took out an aluminum alloy box that was quite heavy, exactly the same as the box that Miss Miki was holding before.

"Mr. Kamoshida, I think this building is also the property of the Noguchi family."

Takato handed the box to Officer Twilight and said.

"Yes...... This building is also owned by the Noguchi Group. ”

Kamoshida said with a solemn expression.

"I see, because it's the property of the Noguchi family, Miss Miki is free to process ......"

Officer Twilight said approvingly.

"In that case, this kidnapping case is actually Miss Miki's kidnapping of her sister and Miss Yuanzi."

Miwako thought for a moment and said:

"She had planned everything a long time ago, wanting to take the billion-yen diamond for herself, and use this mechanism to replace the box containing the diamond with an empty box on the way to transport the diamond, so as to deceive the police and make people think that the kidnappers had taken the diamond without knowing it."

"I don't think it's that simple, because if someone touches the box after replacing it, they should notice that the weight of the box is wrong."

Conan reminded in an innocent tone.

"Let's just ask the patrolman about that."

As Gao Yuan spoke, the patrolman had already arrived on his bicycle, and walked up to Officer Twilight, saluting:

"Police, I heard you have something to ask me?"

"That's right, if what you kid said is true, then the box that the patrolman got at that time should be an empty box with a very light weight."

Kogoro said.

In response, Officer Twilight asked the patrolman:

"I'll check with you beforehand. There was a lady who fell down here before, and when you helped her pick up an aluminum box that looked exactly like this one, what was the weight of the box? Or is it an empty box that is very light to pick up? ”

"It's not an empty box."

The patrolman replied seriously, "It weighs about a few thousand grams, and it should be full of things." ”

Hearing this, Kogoro raised his eyes, looked at Gao Yuan and said:

"You see, it's not an empty box, your reasoning isn't correct."

"Then, Uncle Patrolman, did you feel the cold of the box when you handed it to that sister?"

At this time, Conan stepped forward and asked with an innocent look in his eyes.
