I was in Conan, and after picking up Xiao Ai, I was chased by Hongzi.

"Well, Teacher Judy has already laid down on the bed, and I also put my mobile phone under the pillow." Takagi said.

"The next step is just to be careful not to wake up the teacher and do some tricks in the room." Hattori Heiji said with a smile.

"What did you do?" Officer Megure asked.

"Don't worry, you'll find out later." Otoi Hiroshi said.

"I think we can start the experiment now." Hattori Heiji took out his mobile phone.

"First of all, Mr. Nakamachi sent a text message to Mr. Takai's mobile phone, right?" He walked up to Nakamachi and asked.

"Correct."

"Then I will also send a text message now." Hattori Heiji edited a text message and sent it to Officer Takagi's mobile phone.

"Oh, a text message has arrived."

In the dark room, Teacher Judy was awakened by the sound of text messages, picked up her phone and sat up.

Opening the text message, there was only a simple sentence on it.

【Who are you? 】

"Hey, teacher, have you received any text messages?" Hattori Heiji asked loudly outside the room.

"Oh! yes! This text message is very exciting." Teacher Judy replied with a smile.

"Haha...you deserve it..." Hattori Heiji said awkwardly.

Conan noticed something was wrong, tugged on his trouser leg and asked, "Hey, Hattori, what exactly did your text message say?"

"You don't have to worry about it." Hattori touched Conan's head.

Otoi Hiroshi leaned against the wall and looked at the two of them with a smile.

After all, they didn't know that Judy was from the FBI at this time.

He was still bumping around like a headless fly. Thinking about it carefully, it was a bit too imprudent.

If it weren't for the fact that Belmod had no murderous intention towards Conan, the people on the red side wouldn't be enough for Belmod to handle it alone.

I have to say that Judy's smoke head was very good.

"The next step is for Ms. Shimoda to take photos with the flash." Hattori Heiji looked at Officer Megure.

Officer Megure learned of this and immediately contacted Chiba who was on standby downstairs: "Then, brother Chiba, you can start."

After finishing speaking, Officer Megure asked curiously: "But can this experiment really reveal the secret room murder method?"

"How will you know if you don't experiment until the end?" Hattori Heiji said.

"The last one is Mr. Kawakami, the call he made to the deceased..." As he said that, he dialed Officer Takagi's mobile phone.

"Tch, it's just child's play." Kawakami said unhappily.

Inside the house, Judy immediately answered the phone the moment it rang.

"Hello!"

"Hey, teacher. Let's just talk casually." Hattori Heiji said.

"OK! So what do you want to say?" Judy asked.

"If you ask that, just tell me the answer to the text message just now." Hattori Heiji said calmly.

Otoi Hiroshi glanced at Hattori Heiji with some surprise. He didn't expect that this guy was quite rough, but he would even think of using experiments to kill two birds with one stone.

Maybe he chose the experimental character just now on purpose...

However, it was just a waste of effort.

After hearing his words, Judy's glasses suddenly reflected light.

"OK! But before that, can I ask you a few questions?" Judy said.

"Eh?"

"Who are you? You\u0027re not a mere boy are you. You are more than just a child." Judy asked.

"Yes, yes. I'm just an ordinary high school student." Hattori Heiji replied.

"is this real?"

"Um...isn't the signal not very good? What's going on?" Hattori said suddenly.

"Oh, because the floor here is too high, I often look like this every time I talk on the phone. I'll change places right now." Judy said loudly.

Then, with the safety rope attached, she walked to the built-in window, opened it, stretched out her legs and prepared to step over, ready to walk to the balcony.

"I think you can hear it more clearly here."

As soon as she finished speaking, everyone outside the room heard an exclamation.

"What?! Help! Help me!" Judy kept begging for help.

"What happened?" Officer Memu hurriedly rushed in with people, and then turned on the lights in the room.

At this time, Takagi had already helped Judy stand firmly.

"Thank you, Mr. Police," Judy gasped.

"What's going on?" Officer Megure said, looking at the strange room.

"Yes, the bed has been moved. In order to make the signal of the mobile phone clearer, the teacher took the mobile phone and crossed it all the way across the window on the balcony."

"She intuitively believed that on the right side of the bed was the window leading to the balcony. In fact, that window did not lead to the balcony at all, so Mr. Judy almost fell out of the window like Mr. Takai. .”

"Yeah, you have to ask the person who was still talking to Mr. Takai before he fell - Mr. Kawakami." Hattori Heiji said.

Kawakami lowered his head and said nothing. At this moment, he was almost sober from the drunkenness.

"Actually, Mr. Takai's bed was originally placed in front of the window facing the balcony, but the bed was later moved to the window without a balcony." Hattori Heiji opened the curtains of both windows in front of everyone. .

"I see, if someone calls when he is drunk, and Mr. Takai habitually moves to the window with a balcony next to the bed..." Officer Megure understood.

"Yes, I think the murderer must have been sitting in the living room to celebrate with Mr. Takai over a drink. Then he left his seat on the pretext of convenience, sneaked into Mr. Takai's bedroom and moved the bed."

"Then we move Mr. Takai, who is drunk in the living room, to the bed to rest, and then put his mobile phone next to the pillow. The next step is easy."

"As long as he calls and says he can't hear clearly, he can kill someone." Otoi Hiroshi gave the final explanation.

"But in this experiment, what should I do if Teacher Judy accidentally falls down like this?" Officer Megure said fearfully.

"That won't happen." Conan picked up the rope from the ground. "We just tied a safety rope around Teacher Judy's waist."

"Really! I didn't notice it at all just now." Teacher Judy said in surprise.

"Well...that's what happened. Now please explain to the police the motive behind killing Mr. Takai." Hattori Heiji looked at Kawakami.

"Okay, of course that's no problem." Kawakami said nonchalantly, "But first I have to have a motive to kill, right?"

He sneered and looked at Hattori Heiji.

"What?" Officer Megure asked confused.

"That's right, I did move Tao Jing's bed. Tao Jing asked me to help him change the furnishings in the room. But I didn't expect Tao Jing to fall to death because of this. Even I told him to die. I didn't even hear those words." Kawakami had no intention of admitting his crime.

"Then Takai, just go down and apologize to Hiraya." Conan played the recording left on his cell phone.

It was Kawakami's voice, and his expression suddenly changed.
