……

Looking at the pool of blood at the front of the elevator, Officer Takagi pointed directly to this position and said, "They said they saw two people, and when they were arguing about the envelope in their hands, the power suddenly went out." ”

"Then when the electricity came, they saw the deceased staggering towards the escalator, and the man in the coat immediately ran forward, pulled out of the envelope, something resembling a document, and then ran upstairs."

"That~~~" After listening to such a long paragraph, Officer Twilight felt a little confused, but he still managed to sort out the clue, and then asked.

"The deceased used blood on the top of the envelope, and the three left remember the time. Is it at the entrance of the elevator or escalator? ”

"At that time, I'm afraid the electricity hadn't passed yet."

"Hmm~~~" After nodding, Officer Twilight finally understood what happened to the deceased before he died, and what his mood was.

"I think the dead over there must have been to prevent the murderer from succeeding. Then he took the envelope into his arms. Unexpectedly, the evidence of embezzlement was still robbed by him. ”

Officer Twilight, who was standing at the bottom of the escalator, said with speculation in his tone, "Then the deceased should have been pushed up directly by this escalator." But why didn't the witness, after seeing this, shout out at once? ”

"He thought it was a TV station that was filming this kind of suspenseful reasoning drama, so he didn't speak out immediately."

In fact, when Officer Takagi heard all this, he had to sigh at the first time that person's heart was really big. After all, the blood is all over the ground, and I thought that people would make it into a TV series, what is this?

"All in all, it should be certain by now that the murderer is the one who embezzled public funds over there. The next step is to cut open the top of the envelope. This sign, the circle fork, and the triangle. What does this mean? ”

As he spoke, Officer Twilight pulled the list out of his arms. "As long as you find the 58 people on this list, among the employees of the company who are likely to embezzle public funds, and screen out the most suspects, then you will be fine."

"The difference you are talking about, will it mean multiplication?"

Miss Yuanzi and Xiaolan have been thinking about what the English letter x means today, so they have made bold inferences about the information marked by the deceased before he died.

"As for the rest of the circles and triangles taken together, could it mean a specific mathematical formula?"

"Then the murderer just wrote down the formula, why do you want to express it separately in three characters?"

Miss Yuanzi answered Xiaolan's question with considerable confidence. "It's very simple, the murderer has no way to annihilate the evidence. Therefore, these symbols can completely serve as an idea to hide people's ears. ”

"In your company, is there any employee who is outstanding in mathematics?"

After all, if you want to press Miss Yuanzi, the three characters that represent mathematical formulas are said, then this person should be, and the field of mathematics is more prominent.

"It's not our company, because it's a business. Therefore, the staff recruited are usually mainly liberal arts graduates. ”

“………………”

The first time she directly made this kind of bold reasoning, she was directly overturned by others, but the eldest lady of the garden said that she had no intention of being discouraged, and after touching her chin and thinking for a while, she said guessingly.

"If this is the triangular circle and four-toe circle that represents, then it should be oden, do you think it has anything to do with eating?"

"Do you think it's possible, that fork represents that meaning?"

Xiaolan saw that everyone was using it, looked at her with puzzled eyes, and explained with a slightly red face.

"Actually, it's Teacher Judy, talking about it in class, those cute marks."

"Hahaha~~~~"

Before anyone else asked, what those symbols meant, Teacher Judy covered her mouth and laughed out loud, obviously amused by Xiaolan's cuteness.

Seeing that at this moment, Xiaolan's face was still a little confused, and after Teacher Judy barely held back a smile, he said in a somewhat vague tone.

"I can assure you that it won't mean that way at all."

"You think it's a woman, the one that is unique to the end of the letter."

"This doesn't feel scientific at all~~~" Xiaolan didn't expect that she just mentioned it, and then stood next to Officer Takagi, and she was like this, and directly reasoned out.

"Officer Takagi, then you must know what that x means."

"I see! Then you must have received such a letter, right? ”

Before Officer Takagi could express what he meant by leaving X at the end of the letter, Miss Yuanzi directly began to mock her mouth.

"Not at all, these are all other people's pranks."

"What do the X's you mean by saying less?"

Officer Twilight listened to it next to me, it was a fog, and I felt very dissatisfied, how did it drop, I don't know it for a long time, so what are you talking about? Did you take me into account?

"There's nothing left~~~" When talking about this, Officer Takagi's own face was flushed, and he said directly a little shyly.

"Actually, I can guarantee that the meaning of the X represents has nothing to do with the circle, fork, and triangle this time."

"Maybe this person wrote more than circles, forks, triangles, these things before he died?"

"Hmmm?!!"

Originally, when the group was still struggling with what the x meant, Conan directly took out the envelope that the deceased wrote before he died.

"Come and see, all of you, on the left side of the circle, on top of this side."

Looking at this place carefully, there is indeed a different discovery.

"Look at this, there is really a little bit of blood. Maybe what else did he write besides the circle triangle? ”

"Ah~~~"

After listening to what Conan said, Officer Twilight didn't take it to heart at all, but said with a smile.

"Actually, there is something about this, we have noticed it for a long time. But we've all looked for it, and we really haven't found any similar bloodstains. ”
