"I already know the murderer's modus operandi, and I already know who he is!" said Hattori Heiji confidently to Officer Twilight and the others in the living room. Pen, fun, pavilion www. biquge。 info

"And who's the murderer?" asked Hattori ......," Officer Twilight asked eagerly.

"Don't worry, wait a minute!" Hattori Heiji said with a wave of his hand.

Since Kudo Shinichi didn't come, it means that you haven't solved the mystery of this case yet, it seems that your detective level is not good, so let me solve this case!

After a while, Hattori Heiji said to everyone unhurriedly.

"After killing the victim, it takes at least five to six minutes to complete such a maneuver, from 3:30 to 4:00, so Mrs. Ikemura, who came with us, is not suspicious. ”

A very reasonable reasoning, Officer Twilight and the others nodded.

Then Heiji Hattori said again that the housekeeper who had enough time to prove his innocence was innocent, and although the deceased's son and girlfriend had been upstairs for a minute or two, it was not enough to complete the murder arrangement for six or seven minutes, so they also ruled out suspicion.

In that case!

Then, the next thing is the father of the deceased who has no alibi, the gray-haired old Mr. Ikemura, who is fully suspected of murder.

Hattori Heiji's reasoning was that the head was the way, which made Officer Twilight and others somewhat convinced.

But how did the deceased's father kill the people?

Then, as if he knew everyone's doubts, Heiji Hattori took out a series of fishing lines from his pocket.

"That's what I call a technique, a key item that needs to be used. ”

"Fishing line?" Mori Kogoro and Officer Twilight looked at the long line in Hattori's hand in surprise, not knowing when he got it.

"That's right. ”

"As I mentioned earlier, this was a murder in a locked room. There are two keys, both of which are present in the person who cannot sin. Next, let me do an experiment to see if it is possible to accomplish such a technique in such a closed study. ”

Heiji Hattori took the fishing line and said to Officer Twilight, "The deceased is about the same size as Officer Twilight, so Officer Twilight will cooperate with me and do a simple experiment." Let us see that the situation at the time of the case is restored. ”

"Me?" Stunned, he immediately reacted that this was not a good errand.

"Please, Officer Twilight. ”

After confirming this, Twilight sat down in the deceased's office chair, maintaining a posture of supporting her chin with her elbows on her head. It looks exactly like the deceased when everyone walked into the study.

Because the two people are very close in size, everyone looks at it, whether it is the relatives of the Ikemura family, or Kogoro and the police officers, they all feel a strong sense of substitution.

Next, Heiji Hattori used the long fishing line he had collected, attached it to the keychain from the deceased with duct tape, and then used the fishing line to arrange a simple teleportation device.

From Officer Twilight's desk to the wooden door of the study, the line is like a bridge. Gradually, everyone followed Hattori's reasoning and entered the picture he had set.

After the wooden door of the study was closed, Hattori pulled the line with his hand, and the keychain that had been stuck was drawn into Twilight's pocket, and the tape was separated from the fishing line, and he took advantage of the gap under the wooden door to put away the prop as the key evidence of the 'impossible crime'.

Seeing all this, it was enough to convincingly reproduce the secret room technique, and even Mori Kogoro, who had prepared a statement, had to swallow the doubts that came to his lips.

Because it is indeed possible for the murderer to borrow this fishing line and commit murder like Hattori Heiji.

The eyes of the entire crime scene were focused on this black-skinned high school student.

"It's a very simple method, as long as you use this fishing line, you can deceive everyone's eyes and achieve a secret room murder arrangement. Hattori Heiji said with sharp eyes and confidence.

"So the murderer is this old gentleman, the father of the deceased!"

Hattori's eyes flashed under the brim of his hat, and he turned to point to the old gentleman who was standing between Mrs. Ikemura and Sachiko Katsuragi and had not spoken out all this time.

Hearing this, the deceased's father opened his eyes wide, his whole body was shocked, and his face looked a little panicked and panicked.

Everyone looked over and looked at the old Mr. Ikemura, whose hair and beard had turned gray.

Seeing that Mr. Ikemura, who was pointed out as the murderer, was so frightened, Hattori Heiji, who was good at observing micro-expressions, couldn't help but clench his fists, it seemed that he had won Kudo Shinichi, and he had anything else to say.

Although it is somewhat unbelievable that a father went to kill his son, it cannot be denied in the face of ironclad evidence.

"That's right, I killed my own son, I'm a murderer!" Mr. Ikemura didn't argue too much, and admitted in a complicated tone.

Almost everyone present believed that Mr. Ikemura, who voluntarily admitted his crime, was the real murderer of his own son, and the evidence was conclusive, and he himself had admitted the crime, so the case was solved.

'Sure enough, it's him!' Hattori Heiji thought triumphantly after Mr. Ikemura's own confirmation.

Whether it's a competition or not, because he has won, he has already solved the case, and he also won the high school student detective Kudo Shinichi who has the same name as himself, which can be said to be a very fulfilling thing.

Just when Officer Twilight was about to arrest Mr. Ikemura!

Suddenly, a crisp woman's voice came.

"Wait a minute!

Who?who??

At this juncture, this voice came very suddenly, and it immediately attracted everyone's attention.

Heiji Hattori turned his head, including Mori Kogoro, Ran, and Twilight all looked at the source of the voice.

Is that a girl?

A beautiful girl who feels very beautiful and unique.

The surprised Ran Hattori, the stunned Heiji Hattori, and the confused Kogoro Mori and Twilight all looked at the girl who suddenly appeared here.
