"But, it's not like an ordinary prank at all..."

However, a word from Yoko Okino.

Mizuna Rina's heart, which had just been put back on her chest, was brought up to her throat again.

as predicted.

Mouri Kogoro, who didn't care much at first, suddenly became interested.

After all, before the fact of Besou Zhouping's corruption and bribery was revealed, he thought it was just an ordinary mobile phone loss incident.

"Miss Reina, what's going on?"

A certain tool man said sternly:

"You can't underestimate any clue. Maybe there are some amazing secrets hidden behind it."

What? !

Shui Wulianai was startled.

This... can this be seen? !

Wait a minute, is he suggesting something to me?

A female announcer who reads as Keir and writes as a CIA undercover TV broadcaster now has a serious expression on her face.

That's right, Zhou Ping is rewarded!

That corrupt congressman...

Could it be that this famous detective has been investigating the House election recently, and he found some clues?

No, it's also possible that I think too much.

Must try it out!

Shui Wu Lian Nai calmed down, and while observing the other party's expression, he recounted:

"Here's the thing, because the prank doorbell always happens on Saturday mornings, so once I was ready to catch that person, I waited for a long time by the hallway, and after the doorbell rang I opened the door, but I didn't see half a figure in the corridor..."

"Eh?!"

Mao Lilan said that he was frightened, "It's too weird, right?"

"That's right, I was very afraid to open the door afterwards."

Mizuna Rina also took the opportunity to make a patch for her cautious behavior in the FBI surveillance.

She analyzed that those people in the FBI not only failed to see through the identity of their CIA, but they were even suspicious of whether they were members of the organization.

Otherwise, the situation she is facing now should be even more severe.

As for the famous detective Mouri Kogoro...a little bit can't see through, and needs to be observed again.

"Excuse me, did that incident happen where you live, Sister Rena?" Conan asked.

Um? Who is speaking……

Mizuna Rina's gaze fell on a big head, "That's right, I live in an apartment in Cupido Town."

When Yoko Okino saw this, she also asked if she could ask Mouri Kogoro to go to Minami Rina's house to help with the investigation because she still has work to do.

……

Immediately, the four of them took a car to the apartment where Rina Mizuno lived in Cupido Town.

No need to observe.

The corridor was empty, and there was nowhere to hide.

"Let's try it out."

Mouri Kogoro had no idea for a while, so he had to propose a field test.

Originally, he wanted to calculate the opening time of Sui Wu Liannai, and then calculate the running speed of an ordinary adult to determine whether the prisoner who likes to ring the doorbell of others can run out of the corridor.

Never thought, before the thought was transformed into reality, the door panel in front of him called directly on his face.

"Mr. Mauri, are you okay?"

"No, it's fine... These are all small issues."

Uh……

Shui Wulianai looked at the famous detective who was 'nothing' despite the pain and tears, and felt a little bit in her heart.

Is it an illusion? How do you feel a little stupid...

She was a little suspicious, but she wasn't sure if this was a fake fake intentionally made by the other party in order to relax her vigilance:

"Cough, um, let's go in and talk."

"okay."

Mouri Kogoro covered his sore nose, and after seeing the lock on the door, he couldn't help but sigh:

"No wonder I heard a strange sound just now. It turns out that you have 4 locks installed in your house."

Is this also a test?

Mizuna Rina took every step of the way. After feeling that there should be no language trap in this sentence, she explained with a smile:

"No way, a single woman lives alone, you always have to be careful."

"That's right," Mouri Kogoro scratched his head, "I wanted to say before, whether to change the door to a style with cat's eyes. Now I think that if that one is destroyed, the door lock will not be safe."

"Yes, yes, but I didn't think about it that much."

Shui Wu Liannai's heart froze.

When she chose this place to stay at that time, she just took a fancy to the design without cat's eyes on the door. Did a famous detective find out the problem?

calm down……

She paused, then changed the subject and said:

"Well, what do you want to drink?"

"Coffee bar, just to refresh myself," said Kogoro Mouri.

"I'll help too." Maurilan followed to the kitchen.

Conan was completely unaware of the image of a certain organization cadre battling with the air. After confirming that the three of them had left the entrance, he hurriedly took out a gum and wrapped the bug inside, and stuck it to the outer wall of the main entrance.

As long as the person who rang the doorbell reappears, he can directly hear the sound in the corridor outside...

To be on the safe side, in order to prevent the stickiness from disappearing, the bug rolls off to other places, and install another tracker.

thinking.

He opened another button of his own and wrapped the props inside into the chewing gum.

Now there's no problem... eh?

Suddenly, Conan frowned, vaguely aware of the prying eyes from the building opposite.

He turned his head and looked over there, but found no clue.

...is it an illusion?

"Conan, what's wrong with you?"

At this time ~lightnovelpub.net~ did not wait until Maorilan, who had entered the house, came out to investigate the situation.

"I'm looking at the door lock, hehe..."

Conan showed a simple and honest smile, hurriedly changed his shoes and ran to the living room.

in the living room.

Mouri Kogoro is asking Reina Mizuno about the specifics of the matter.

It was two months ago that I learned of the prank doorbell.

That is, Mizuna Rina switched from the "Good Morning Seven" program to the news interview on Sunday night.

Conan couldn't help but ask:

"Then for the past two months, every prank doorbell has been on Saturday morning?"

"Hey, by the way, I remember last week from Monday to Friday, I was interviewing abroad, but I didn't hear the doorbell on the Saturday morning after I came back."

Shui Wu Liannai said this with some hesitation:

"However, it's also possible that I was too tired and slept so deeply that I didn't hear it, ah... Also, I remember that on the Tuesday after the holiday in October, it wasn't just the doorbell, but the other party also played outside my door. I found a bottle with a strange capsule in it... Then I took it to a clinic with a good reputation and asked about it, and I learned that it actually contained sleeping pills."

"Sleeping pills?!" Mao Lilan was shocked.

"Maybe this is a warning that the other party is going to commit a crime!"

Mouri Kogoro's face was serious, "Maybe he wants to make you dizzy, and then plots to do something wrong!"

"Speaking of which, tomorrow is Saturday."

Conan murmured while resting his chin in one hand, unconsciously remembering the gaze he had cast on the building opposite...
