In the face of Kudo Shinichi's question, Suzuki Seimei said with some doubts: "Brother Shinichi, isn't it just killing someone? Is it necessary to be so complicated?"

Is it necessary to be so complicated? It needs to be that complicated...

Suzuki Seimei's voice was like an echo, constantly echoing in Kudo Shinichi's mind, making him smile involuntarily: "You...you're right, we think too much ourselves."

The murder case this time is actually very simple. The biggest difficulty is to use the inherent thinking of the detective to make them subconsciously think that no one dares to kill in front of the detective, so they will immediately rule out Mrs. Tsujimura, the biggest suspect. .

Although Kudo Shinichi had already deduced that Mrs. Tsujimura was the murderer, he also noticed the misleading clues left by Mrs. Tsujimura before, and was almost brought into the pit by her.

On the other hand, Seimei Suzuki, an amateur detective, is not limited by this inherent thinking, and can ignore the misleading clues that Mrs. Tsujimura deliberately left.

I didn't expect that I would be taught a lesson by this little devil. Life is really impermanent~

"Brother Shinichi, I advise you to put on your clothes quickly, otherwise you will really die when Sister Xiaolan comes with the doctor." Suzuki Seimei stared at Kudo Shinichi for a while, his face speechless 's reminder.

If it was Maurilan naked, Suzuki Seimei wouldn't mind chatting with her for a while.

But when it was changed to Kudo Shinichi, Suzuki Seimei always felt a little gay, so it would be better for him to get dressed quickly.

When Kudo Shinichi heard Suzuki Seimei's words, he finally came back to his senses, and hurriedly took out a set of clothes that fit better from the closet and borrowed them temporarily.

On the other side, Hattori Heiji, who managed to find a ball of fishing line from a hidden corner of the house, returned to the murder scene with confidence.

"Kudou, if you don't show up again, I will win this competition."

Hattori Heiji glanced at everyone and found that Kudo Shinichi had not yet appeared. He was extremely confident: "Everyone, I already know the method used in this secret room murder case, and who the murderer is."

"Nani? Have you unlocked it?"

When Kogoro Mouri, who was still thinking hard, heard the words, his expression changed slightly, and he secretly slandered: "Damn it! Why hasn't my second personality appeared yet? Shouldn't I really let this kid in the limelight?"

The faces of the police officers present also became more subtle. Although the Tokyo Metropolitan Police Department and the Osaka Metropolitan Police Department are both subordinate to government departments, the Metropolitan Police Departments in different regions also have great competitiveness with each other.

Hattori Heiji is not only a high school detective in Osaka, but also the son of the Osaka police chief.

If this kid really wanted to solve the case before them, Police Officer Matsumoto could already imagine the scene of Police Chief Matsumoto spitting on him.

"Brother Maori, you are too useless~" Officer Mumu couldn't help but complained, "Hurry up and start sleeping!"

╮(─▽─)╭

Mouri Kogoro's face was full of confusion: "Officer Mumu, you are too embarrassing for me. I can't fall asleep if I want~"

"Let me explain to everyone the method of this secret room murder case!" Hattori Heiji walked up to Officer Meguro and asked with a smile, "Officer Meguro, can you please play the role of the deceased and cooperate with you? What about me?"

"Ah? Oh... OK."

"Then please sit on the chair that the deceased sat on before, and then keep the posture of the deceased before he died."

"..."

Officer Meguro glared at Kogoro Mouri resentfully, and then, like a puppet, following Heiji Hattori's instructions, he put his chin on his hand and sat down on the chair obediently.

"Everyone, at the time of the crime, the windows in the study were closed, and the only door that could be entered and exited was also locked, forming a perfect secret room."

Hattori Heiji straightened the peaked cap on his head and followed the conversation, "But in this room, there is actually a passage leading to the outside, more precisely, it should be a gap!"

"Gap?"

When Maori Kogoro heard the words, he was stunned for a moment, then he reacted instantly, and set his eyes on the crack of the door: "You mean the crack of the door!"

"That's right!"

Shibu Takagi said with a puzzled look: "But the crack in the door is so small, how can I put the key in the prisoner's pocket?"

"It's very simple, just use the fishing line to cooperate. This group of fishing line is the one I found in this house just now." Hattori Heiji finished, took out the fishing line he just found, and began to show it in front of everyone. Demonstrate the modus operandi.

With the unrequited expression on Officer Meguro's face, Hattori Heiji first used a fishing line with an iron needle to pass through his trousers pocket, then pulled the two ends of the fishing line and slowly walked out of the door, locking it with a key. the door.

"Swish..."

After closing the door tightly, Hattori Heiji pasted the fishing line on the key pendant~lightnovelpub.net~ and then slowly pulled the fishing line on the other side, and the key slowly entered the study under the traction of the fishing line. Glide all the way, and finally landed in the pocket of the police officer Mumu.

After the key successfully entered the pocket of Officer Mumu, Hattori Heiji pulled it hard, and the fishing line suddenly slipped out of the tape and was successfully recovered by him outside the door.

When everyone present saw this, they suddenly realized: "So that's the case. If this happens, it will be a perfect secret room."

(￣ε(#￣)☆╰╮(￣▽￣///)

Although Police Officer Meguro felt a little pain in his face, he had to admit that Hattori Heiji's reasoning ability was very strong, and he was able to solve this secret room murder case so quickly. He was indeed a famous high school detective in Osaka.

"It takes at least five minutes to kill someone with this method, and the time of death of the deceased is between 3:30 and 4:00 in the afternoon."

Seeing that everyone was startled by his own reasoning, Hattori Heiji unhurriedly said: "So at four o'clock in the afternoon, Mrs. Tsujimura, who came back here with us, can be the first to rule out the suspicion.

And between three and four o'clock, butler Koike, who had been chatting with the neighbors nearby, also had no time to commit the crime.

As for the deceased's son and his girlfriend, although they also went to the second floor halfway through, it only took about two minutes, which was not enough time to complete the killing method just now.

In this way, the only person who can commit the crime is the old Mr. Tsujimura who came here only after two o'clock, and has been watching TV in the room next to the study! "

!!!∑(?Д?ノ)ノ

Tsujimura Guishan heard the words, shook his head without thinking, "What? Impossible! How could the murderer be grandpa?!"
