On the roof of the Kaido Building, the cigarette in Kogoro's mouth burned to the end again-

I don't know how many of them are, and during this time, everyone has been paying attention to the roof of the Noguchi Building, but they have not noticed anything unusual so far.

"It's weird. Thirty minutes have passed since the appointment was made, and there is nothing unusual about the balloon advertisement or the box containing the diamonds. ”

Officer Twilight questioned the police officers who were on guard around the area over the intercom, but he didn't find anything unusual, so he said with an anxious expression.

"yes, the kidnappers didn't come to get the diamonds?"

Kogoro nodded and said in surprise.

"Everything is normal at the main entrance."

"There's nothing unusual about the back door."

At this time, from Officer Twilight's walkie-talkie, the report of Wataru Takagi and Miwako came again.

"Would you like to put the balloon down and take a look?"

Xiaolan said anxiously.

"Not yet."

Although Officer Twilight looked anxious, he still forced his composure and said:

"Although I don't know what the kidnappers have planned, it's likely that they are just testing whether Miss Miki has called the police, and rash action will cause unnecessary trouble."

In this way, everyone was very helpless, but they could only wait silently.

Another thirty minutes passed, and there was no change in the advertising balloon floating in the air.

"It's been almost an hour, hasn't it?"

Looking at the time, even Officer Twilight put down his binoculars and said helplessly with an expression of wanting to give up.

"Yikes!"

At this time, Kogoro seemed to notice something, held the binocular, and suddenly shouted:

"Officer Twilight, there's finally movement!"

Hearing this, Officer Twilight hurriedly picked up the binoculars and continued to look at the top floor of the Noguchi Building, only to see Miki Noguchi taking out her mobile phone and seemed to be about to answer the phone.

"Officer Twilight, it looks like a kidnapper is calling."

Located on the top floor of the Noguchi Building, Conan, who was watching the scene up close, spoke to Officer Twilight through a pocket microphone.

In this regard, Officer Twilight immediately ordered the police officers around him to bring the equipment that monitored the mobile phone, put on headphones, and began to listen to the content of the mobile phone-

"Hey!"

Miki Noguchi's nervous voice was transmitted through the monitors to Officer Twilight's headphones.

"I got the diamonds."

The mechanical voice transformed by the voice changer just said this sentence and hung up the phone.

"Hey! What did you say! Feed? Feed! Feed! ”

Miki Noguchi's grief-stricken voice came from the police's headphones.

"Let's get started!"

Hearing this, Officer Twilight resolutely ordered.

"Yes!"

On the intercom, the police officers responded.

At the same time, Kogoro and Koran also ran to the stairs with Officer Twilight.

Meanwhile, on the roof of the Noguchi Building, Wataru Takagi and Miwako, who arrived earlier, were already sitting around the balloon advertisement with the box hanging on it, trying to pull the rope and put the balloon down.

"You'd be quicker!"

On the roof of the building, Miki Noguchi, who was shivering from the cold, ordered with an irritated expression.

"We're doing our best."

Wataru Takagi pulled the rope desperately, and finally put down the aluminum alloy box and took it into his hand.

"Good...... It's so light! ”

Holding the box, Takaki Wataru felt the weight in it, and his face immediately changed.

"Impossible!"

Miki Noguchi said angrily and snatched the box-

"Really...... It's so light! ”

Miki Noguchi's expression turned blue for a moment, and she said in surprise.

Gu Xuan

When she adjusted her mentality and regained her mental preparation, she quickly opened the box-

But inside, it's empty!

"How...... How could it be ......"

Miki Noguchi was stunned, couldn't believe her eyes, and looked at the faces of the people around her, but the faces of Conan and the others were the same, showing stunned expressions.

"Not a single diamond is gone!"

When Kogoro arrived, he saw that there was nothing in the opened box, so he couldn't wait to stick his head into the box, not letting go of a corner, and carefully inspect it.

"Gone...... The diamond is gone! ”

Miki Noguchi muttered, slumped on the ground.

"Miki-san!"

Kamoshida suddenly stretched out his hand and helped Miki Noguchi.

"Look, there's a letter in there!"

Conan said, sharp-eyed, pointing to an envelope attached to the back of the lid.

In this regard, Officer Twilight put on gloves, immediately opened the envelope, took out the stationery inside, and read it:

"I will release the hostages as agreed. Look for it on the benches in Rice Flower Central Park. ”

"If it's Rice Flower Central Park, it's about a twenty-minute drive from here."

Wataru Takagi thought for a moment and said the distance.

"Sister Yuri...... I'll leave it to you. ”

Miki Noguchi, who is blinded and can only stand on the support of Kamoshida, pleads with Officer Twilight.

"We're on us!"

Officer Twilight said seriously, "We'll definitely bring Miss Yuri back." ”

So, everyone hurriedly ran off the roof, got into the car, and prepared to go to Rice Flower Central Park.

In this regard, Gao Yuan, who parked the car near the entrance of the Noguchi Building, looked at the scene of Officer Twilight, Kogoro, Conan and others getting in the car and leaving, and couldn't help but look indifferent-

"Sure enough, Miki Noguchi didn't show up."

……

In the empty rice flower central park, the wind is cold, and there are basically no pedestrians.

Takagi Shibu, who arrived first, looked around the park, and there were many places with benches.

"There are too many benches, which chair is it?"

A little irritable, Wataru Takagi said, looking around left and right.

"Investigate them all!"

Officer Twilight, who arrived from behind, gasped and gave instructions.

"Yes!"

After receiving the order, all the police scattered around the park together, while Conan silently observed the panoramic view of the park.

At this moment, a bench located in the depths of the park came into his sight, on which a small balloon of the same shape as the advertising balloon was firmly tethered.

"Where!"

Conan shouted as he pointed to the bench, and ran over with a puff of smoke.

"Conan!"

Xiaolan was the first to follow, and then Kogoro and the others also ran in that direction.

"So there it was!"

When Wataru Takagi heard the voice, he immediately turned around and hurried over, and Officer Twilight and Miwako followed behind Conan.

Conan was the first to arrive, took down the envelope tied to the balloon, and took out the stationery inside—

"The two of them are in the basement of the Kaido Building!"

Looking at the words on it, Officer Twilight, who arrived later, couldn't help but pause-

"There it is!"

I thought that the police had been on the roof of the Kaido Building to observe the roof of the Noguchi Building, but I didn't expect that the hostages were in that building at that time.

Faced with such a situation, Officer Twilight immediately took out his mobile phone and asked Kamoshida about the situation, and learned that the building did indeed have a basement, and the key was with the building administrator.

So, everyone immediately set off and returned.
