"Really? The deceased had caviar on his hands in box No. 3 and did not go to the bathroom to wash it, but couldn't wait to run to box No. 8 and wait for someone? Is it that urgent? Not even half a minute? "Ahh

Shizuo Furuimon moved his wrist and walked towards Professor Iwama, pressing one hand on his shoulder with a slight force.

"I'll talk about it later, my patience is limited."

Professor Iwama's heart was pounding, his eyeballs were fluttering rapidly in his sockets, and his brain was racing to try to come up with a plausible statement.

But before he could speak, he heard a voice—"Huh? ”

When everyone heard the sound, they saw Conan holding a briefcase, squatting there and flipping it, "Professor Iwama, you actually have a tape recorder in your briefcase?" What is it used for?

And I remember that when the deceased left Box 3, he shouldn't have served the food yet, right? How did he come across caviar? It's amazing~"

Professor Iwama's face turned pale suddenly, "Where did you come from, who told you to rummage through my things?" "Ahh

As he spoke, he wanted to snatch his briefcase back, but he couldn't move at all when he was pressed by Shizuo Komimen.

"Do you want to continue to quibble? Continue to delay everyone's time? Gumeimen Shizuo said coldly with a kind face.

"Tell me, then, what do you mean by my alibi? How did I get here and kill people? ”

Professor Iwama is still hard-mouthed, but his face is more unwilling.

Gumeimen Shizuo sneered: "Why should I know about that kind of thing? Once you're in the interrogation room, you'll take your time to explain. ”

"You're threatening and intimidating!" Professor Iwama panicked.

"So what? Takagi, go close the door ...... "Tsuh."

"That's right, isn't it?"

As he spoke, Conan's voice suddenly sounded, interrupting the beginning of the scorching atmosphere.

I saw that he didn't know where to get the ice cubes, and the paper bag of Kuaiko, plus the rubber bands and pins that were turned out of Professor Iwama's briefcase, were tinkering at the window for a long time.

The crowd watched as the ice melted, wetting the paper bag, then suddenly disconnected, and the window slammed shut with a rubber band.

"I see!" Shiratori Ren Saburo suddenly realized, "If you cooperate with the tape recorder to play the pre-recorded sound, you can pretend that the person is still in the third box!" ”

"Conan, how did you know?" Mao Lilan asked curiously.

Conan scratched his head, leaned over and whispered to her very calmly, "I just called Shinichi's brother, and he told me~"

Maorilan immediately believed.

"Physics professor, huh? Are you good at designing this kind of small mechanism? Shizuo Komimen grabbed Professor Iwama by the collar, "It's time to get off work, don't delay your efforts!" ”

His trick was seen through by the elementary school students at a glance, and Professor Iwama's psychological defense line suddenly collapsed, and after Shizuo Furumon let him go, Putong suddenly knelt on the ground with a bitter and unwilling expression.

"That's right, I killed him, I hid in the big wooden boat that delivered the food, and went down the canal to room eight.

I killed him because he knew that I was publishing a student's paper under his own name, and he threatened that it was not enough for me to promote him to associate professor, and he extorted 50 million yen from me.

I'm afraid he'll continue to get worse and keep going, so I'll ......"

Gu Meimen Shizuo was a little speechless, what is wrong with these murderers, he likes to listen to a reasoning show, and then he also likes to confess. Diaphragm

Did I ask you this? Go to the Metropolitan Police Department and explain it slowly.

After Professor Iwama finished speaking, he looked at Shizuo Komimen with a bit of hysteria.

"Why failed! I've done so much preparation and designed such a perfect plan, why do you doubt me all of a sudden? ”

Just now he clearly presented an alibi, and the result was that this person asked his subordinates to search him for no reason, as if he already knew that he was the murderer.

"There are so many whys, I have no obligation to explain it to you."

Gumeimen Shizuo can't explain the Maori elimination method anyway, and they are still half-convinced by Shiratori, let alone outsiders.

Ren Saburo, the white bird on the side, thought for a while, and suddenly said: "I have analyzed and summarized your method of breaking eucalyptus from the Gumeimen Police Department before, and I have gained a little from this. Diaphragm

If a case involves a ruse, then it means that the murderer is trying to confuse the public and try to clear his suspicions.

And trying to clear one's own suspicion just shows that the murderer is suspicious, either he knew the deceased and has an easily verifiable motive for killing, or he has been at the scene of the eucalyptus. ”

Shiratori Ren Saburo said and pointed to the knife on the deceased's chest, "The murderer brought his own weapon, which was obviously premeditated, otherwise if it was a murder of passion, the murder weapon should be inherent in the scene of the eucalyptus, or something that the murderer carried."

From this, it can be seen that the murderer of this case will not be a stranger who does not know the deceased, for example, Miss Kyoko Anzai, who has been to the scene, but will not be the murderer.

Since it is certain that the murder was premeditated, the murderer is obviously between the two of you who are traveling with the deceased.

And the alibi of the two of you is obviously that Iwama taught you that it is easier to cheat, and it was your order that Lecturer Arai went to buy cigarettes.

Gumeimen Police Department, you just thought like this, right? "Ahh

"Well, almost......"

Gumeimen Shizuo responded with a lake, so I just thought about it so much? How come you have no memory like a Maori detective......

Shiratori Ren Saburo was so affirmed by him, and suddenly felt that his efforts during this period of time were in the right direction, at least he understood the detection idea of this case more profoundly.

Professor Iwama opened his mouth, his face was ashen, he tried his best, but the result was useless, the police had a complete set of analysis methods, and what he did was trying to cover up.

"Your doubts are solved, I have something to ask you." Gumeimen Shizuo suddenly spoke, he rarely asked anything, but at this time he was really a little curious.

"How did you kill the dead without splashing blood?"

It stands to reason that a knife to the heart should spurt blood. Diaphragm

Professor Iwama laughed to himself, "This is one of the preparations I just mentioned, I studied and practiced for a long time to avoid getting bloodstained.

There are two situations that can reduce this probability after the knife is inserted into the heart, and one is that after the dagger is inserted, try not to move and not expand the wound.

The other is that the right atrium has one of the lowest blood pressure levels in the body, and piercing this area can also kill people quickly, but it will not cause blood to spurt everywhere. ”

Hearing this, everyone observed the scene of the eucalyptus, and sure enough, the blood flowed down the clothes of the deceased, and the amount was very large, but it was not sprayed everywhere.

"Not only that, but I also deliberately ordered a blood clam, in case I accidentally got a little blood, I can also use the blood on it to cover it up and confuse the luminol test.

It's just that I didn't expect that because I was too focused when I was killing, my mind was all on the angle and position of the dagger's piercing, and I didn't notice the caviar on my body......

If it hadn't been for this accident, I would have been able to clear my name. "Ahh
