"What's going on with these reporters? Why are you doing at the door? Go in and see who is dead!"

Organizational logistics.

The Deligan hid in the office with the supervisor, secretly watching the real-time situation on the front line.

After waiting for a long time, I saw the shaking camera always stopping at the door. The hard-working general couldn't help but shake his head: "Will the police be a reporter? If the police don't let him in, they will go to the side door or slim up the window. They are so rude and anxious."

The supervisor typing the keyboard and recalled the information submitted by this subordinate before: "Is there a landlord's wife, her grandson, another college student, and a Calvados who had just moved in. 1/4..."

The two of them looked at the scene in front of them, praying that the reporter would advance as soon as possible, and as if they were gambling with horses, they couldn't help but feel excited and sweaty.

...

In the apartment.

Although the materials for the key ties were a little strange, Kogoro Mouri still adhered to his point of view based on the principle of being down-to-earth: "But this is a secret room. If it weren't for suicide, this person could not be a demon."

Conan couldn't stand this unbelievable uncle anymore, so he raised his hand and pointed: "Who said it was a secret room? Isn't there a breath window open there?"

As soon as he finished speaking, he heard a buzzing sound on his head.

Kogoro Mouri took back his fist that knocked on the fake elementary school student and snorted: "That breath window is only wide. Not to mention adults, under normal circumstances, even a baby cannot get through."

Conan's eyes twitched, and he wanted to refute it, but after seeing Calvados nearby, he had to swallow the words he poured to his mouth in a frustration: "..." pointed out the matter of the ventilation window, and could use "children are good at observing", but if he said more, the organization discovered his abnormality, things would be bad.

Fortunately, there was a very reliable classmate next to him who seemed to see the embarrassment of the mini detective. In Conan's eyes looking at the savior, Jiang Xia said to Officer Megumi: "There is one thing a bit strange. When we found the body, all the lights in this room were dark."

"I heard that there was only one wound on the deceased--even though it wasn't dark when he died. But the bathroom was in the middle of the room with no windows. Even during the day, it would be very dim if the lights were not turned on.

"It is actually not easy to think of the arteries on your arm in that environment."

The police department of Memu nodded repeatedly: "It's indeed a bit strange to say this... Maybe the murderer had killed someone in the bathroom, and when he went out, he shook his mind and turned off the light habitually."

“…”

Kogoro Mouri thought about it and gradually felt something was wrong. He leaned over to Jiangxia and asked whispered: "Is it really him who killed him?"

Jiang Xia nodded and whispered: "The murderer is..."

Conan, who was tiptoeing over their conversation: "!!!"

He grabbed his soundproof headphones, but it turned out that everyone seemed to have a quick answer personality - before he put the headphones on his head, Kogoro Mouri suddenly realized: "I understand, I understand everything!"

Conan: "…"

Very good. According to Jiang Xia's character of respecting the elderly and loving the young, since Uncle Maori said that, he should politely let the old senior neighbor perform. And he can brainstorm during this period and come up with the answer...

While thinking, he patted his forehead: My mind, don’t think about those messy things, move quickly!

Next to him, in Calvados' impatient and curious eyes, Kogoro Mori began his reveal: "This is actually a homicide incident!"

The police department of Meguru looked at him and then looked at Jiang Xia: "..." Don't think I don't know why you changed your mind. You guys have peeked at the answer, right?

But no matter what, it is a good thing to solve the case. A tired old police officer took advantage of the situation and said, "Oh? Then tell me."

Kogoro Mouri smiled and took everyone back to the entrance.

He pointed to the mailbox that he opened: "After killing Mr. Azhen, the murderer left the room and locked the door. Then he used the opening of the mailbox to send the keys into the model's pool from outside the house.

"Just use a long piece of steel wire to pass through the crossbar in the water of the building model, and then pull the other two ends of the steel wire to the entrance and through the quotation port, you can hang the key on the rope ring after closing the door, and then send it into the water by turning the rope ring.

"After entering the water, the toilet paper strip on the key melted and broke by the water, and it stayed in the water, and the wire was taken out of the door by the murderer. In this way, a murder scene in a secret room will be formed!"

"So that's it!" The police department of Memu was about to applaud, but at this moment, the police officer Takagi next to him suddenly thought of something.

This young policeman who almost lost to Officer Shiraki in the last public toilet case had already been working hard to make up for a lot of knowledge of solving the case. After listening to Kogoro Mouri's reasoning, he whispered: "But from this room to the entrance, there is a door frame close to a right angle in the middle, and the key can easily get stuck there."

"This..." Kogoro Mouri choked, but soon had a flash of inspiration and snapped his fingers, "Just relax the rope and throw it away when the key is stuck, you can get the key to cross the door frame. Then tighten the rope again and implement the plan I just mentioned."

Conan: "..." He could actually come up with such a way to close the door... Is this confused uncle smart or stupid?

Next to it, Jiang Xia pointed to the chaotic crayon graffiti on the wall: "These crayon drawings seem messy, but if you look closely, you will find that they are deliberately painted on the edges and corners of the door frame - so that if a key or steel wire passes through the door frame, it will scrape off the crayons that were painted there in advance."

"But now, the crayon drawing is unscathed - that is, the murderer had thought in advance that someone would make the reasoning like Uncle Maori just now, so he first used the method of painting crayons to let us give up this idea and turn our thinking on solving the case to suicide."

"What?" Kogoro Mouri was shocked, "That person actually expected my thoughts?"

He learned from his mistakes, thought about new tricks, and gradually looked at the door lock: "That's..."

Jiang Xia interrupted before he was embarrassed for the second time: "In addition, there are also crayon marks passing by on the door lock and knob on the inner side - so the murderer did not tamper with the door lock."

Kogoro Mouri: "..."

Who is the murderer? He is a veteran detective and has been predicted twice!
