"In other words, it can be split, and the money can be divided among several people."

Eisuke said.

"But it's only 150 yen in total, and if you split it up, you won't even have enough money to let the children run errands."

Miss Today's son said helplessly, "Would adults share such scattered money together?" So it's still not right. ”

In this regard, Gao Yuan also agreed, and it seemed that he still needed to continue to think about it, and then thought about it for a while and said:

"By the way, we missed an important point in the previous analysis."

Gao Yuan proposed: "The man didn't say 'five still missing,' but 'five more.'" This clearly indicates that the ten coins he needed were an approximate amount. It is true that he may need fifteen coins, but not necessarily fifteen, it may be fourteen or sixteen, and that's why he says, 'I still have to have' five! ”

"That's right! That's it! ”

When Miss Kambiko heard this, she smiled excitedly and puffed her hands, looking extremely cute.

"In other words, the number of coins he needs, he only knows an approximate amount, because he wasn't sure how many ten yuan coins he needed at the time!"

"Please wait a minute, then this doesn't conflict with what I said can be distributed to other people!"

Hidden Pavilion Esuke said, showing his presence.

"Yes!"

Miss Kimako seemed to have a new train of thought, and said with some cheerfulness, "This is very delicate. Fifteen or sixteen coins at most. Dividing such a small amount of money among a few people is normally unreasonable. ”

"In other words, you can't think about the use of coins in the normal way of thinking now."

Gao Yuan said, "Then let's sort out our thoughts first." The man had to pay 10 yen, and about a dozen coins, and he couldn't replace it with other coins, 5 yen, 50 yen, he had to do it with 10 yen. ”

"Ahh Will it be going to a convenience store to make a copy! ”

Hidekan Esuke suddenly thought of something and exclaimed, "I remember that the copy fee at the convenience store is exactly ten yen." ”

"No, it won't."

"Impossible."

Gao Yuan and Kyoko took turns to deny the statement of the hidden pavilion Ersuke.

"I guess it'll cost a hundred yen to make extra ten copies."

Miss Kyoko said.

"And even if you ask for 10 yen, you can change it at a convenience store, so there's no need to call someone."

Gao Yuan said.

"That's right...... So, is there any other reason? ”

Hidden Pavilion Esuke said dejectedly.

So, the scene fell silent again, and then suddenly, Miss Today's child let out a lovely exclamation sound, as if she had thought of something surprised, and said happily:

"I thought of it! There is only one thing, and you have to use 10 yen coins. ”

"What's the matter?"

Gao Yuan said in unison with the Hidden Pavilion Ersuke.

"Pay phone!"

Smiling, Miss Kyoko gave the answer.

Because Takato is not Japanese in nature, he didn't think for a while that there were still public telephones that could be used on the streets of Japan.

But when he heard this answer, Gao Yuan's thoughts were immediately blown through as if they had been blown up by lightning - in this way, all doubts could be solved! And the suspicion of Eisuke Hidden Pavilion can be cleared, because the real murderer of the two murders he met was that man!

"Public telephone...... By the way, do you want to use 10 yen coins to make a call? ”

Eisuke Hidden Pavilion is also a little unfamiliar with this word, so he asked.

"Yes."

Ms. Kyoko replied with certainty, "Basically, there are only three types of coins, 10 yen coins, 100 yen coins, and phone cards. Ten yen can be played for a maximum of one minute at a time, and you can continue to flip coins, but you will not give change. ”

"If it's a pay phone, is that person going to call for a long time with this pile of ten yen coins?"

Ekōkan asked.

"That's not right."

Gao Yuan had already clarified all his thoughts, and said with some calmness, "If you plan to talk for a long time, you should use a hundred yen coin, or use a phone card." With so many 10 yen coins, it is to hit many times. ”

"No, wait a minute!"

Hidden Pavilion Esuke couldn't accept this answer, "There's a big problem with this statement!" ”

"The man, who was holding his phone."

Takato added that he said what Eisuke wanted to say, "You want to say this." ”

"Yes, under normal circumstances, if you have a mobile phone, you should use your mobile phone to make a call!"

Eisuke said.

"However, the phone cannot hide the identity."

Gao Yuan said, looked at Miss Kwako on the side, and found that she seemed to look at herself with a cheerful expression because of what she had just said, and nodded, it seems that the two of them have the same idea.

"What's going on?"

Ekōkan Esuke looked at the interaction between the two detectives in front of him and asked a little unpleasantly.

"For example, if I call you with my mobile phone, my mobile phone number will be left in your call log. Of course, if you set it to call hidden, the phone number will not be displayed, but this can only fool the record, and if you go to the operator, you can still find the other party's number. ”

Takato explained.

"And if you call from a public phone, whether it's you or the operator, only the public phone number will be recorded. After that, even if someone went to check this record, they didn't know who exactly hit it. In this way, it is possible to hide the identity. ”

Miss Kyoko added.

"But why be so cautious!"

Hidden Pavilion Osuke said loudly, "Ordinary people don't care about this kind of record at all, after all, almost no one will check the operator's record!" ”

"But someone will look up."

Gao Yuan said, "Ordinary people can't check it, but the police can—that person wants to hide it from the police." ”

"In other words, Mr. Hidekan, the man you met and the person on the other end of his phone were planning to commit some kind of criminal action."

Miss Kyoko said.

"Crime!"

Hidden Pavilion Esuke exclaimed, "What kind of crime? Phone scams? ”

"Mr. Hidekan, have you forgotten your appeal when you entrusted us?"

Gao Yuan reminded, "Isn't the facts of the crime already in front of you?" ”

At this, Hidekan Esuke's mouth opened wide in surprise, completely unable to understand why the detective in front of him was able to go back to the two murders he encountered from the matter of coins.

"Then let's think about it from the direction of the coin."

Miss Kyoko saw the incomprehensible look on Esuke's face, so she proposed, "That person wants to make a pay phone with a dozen coins, and it can be inferred that his call is not long, and he has to call many times, only for a short time at a time. Looking at it this way, Mr. Hidekan, do you think he wants to fight in the same place, or in different places? ”

Hearing Miss Kyoko's words, Hidden Pavilion Osuke immediately replied, "If you call from the same place, it's a harassing call!" ”

"But the problem is that the man was also talking to another person, and it can be assumed that that person was also involved in the crime, and it is unlikely that there was an accomplice in making harassing phone calls."

Gao Yuan prompted.

"If it's not a harassing call, it's a call to a different place."

Eisuke said.

"Yes, call to different places, each place does not exceed a minute of calling, judging from the number of coins, it should be about ten places."

"Of course, in my personal opinion, I think that the place where you should call is a little less than the total number of coins, and the extra coins are to prevent the call from running out. ”

"Ten yen coins can only be played for about a minute, and if you say too much, you have to put in a spare coin to prevent it from timing out. In order to prevent this, you need to prepare some coins, even if you are not sure how many. ”

Gao Yuan said, "That's why there is such a saying, 'I have to have five'." ”

"To about ten scattered places, you can make a phone call for a minute in a row, and it is related to crime."

Miss Konko said, slowing down and then asking a question as if enlightened.

"Ten or so places means a wide range. Doing things in a minute means it's easy. Playing continuously means 100,000 urgent. What is this like? ”

"Looking for someone?"

Ekute replied with some uncertainty.

"That's right! That's it! ”

Miss Kyoko seems to be satisfied with the speed of Esuke Hidekan's reaction.

"They were looking for someone, but that person had about ten alternative addresses, but they couldn't pinpoint which one they were, so they decided to call."

Gao Yuan said.

"So they're going to arrest someone?"

Ekōkan asked.

"Nope."

Gao Yuan shook his head, "If the target wants to escape, it is not easy to deduce the address through the phone. Mr. Hidekan, if you want to run away from someone, and a call suddenly comes from your hideout, will you answer? ”

"Definitely not!"

Hidden Pavilion replied.

"Yes. Therefore, the other party is a person who has not noticed that he is being targeted, and he should be an ordinary person who has passed the day. ”

Miss Kyoko said.

"How can ordinary people be targeted by criminals?"

Hidden Pavilion Esuke was puzzled.

"It's more common to see things you shouldn't be looking at — for example, last night's murder."

Gao Yuan changed the topic and directly turned to the matter entrusted by Hidden Pavilion Esuke, but it seemed that the turn was too fast, and Hidden Pavilion Esuke still couldn't understand the relationship, feeling that the logic was too little, so he showed a shocked expression again.

"Mr. Detective, you're turning too fast."

Miss Jinzi rebuked Gao Yuan coquettishly, and then said, "This kind of put aside in advance, Mr. Yinguan, how much do you think those two people know about the target?" ”

"There are about ten alternate addresses, a little too much, and the fact that they can't lock them shows that they have limited information in their hands."

"If you know the target's 'surname' and 'street of residence', and then use the local phone directory to choose, there should be about a dozen ......."

As he spoke, Gao Yuan felt that he was about to say the correct answer, so he shut up.

"Voice?"

"They know the target's surname and address, and the more information they need is to know the other person's voice, otherwise they wouldn't be able to confirm the target with such a short phone call!" ”

"So, the final question, what kind of people are targeted?"

Miss Kyoko continued to ask.

But this time, Hidden Pavilion Esuke thought about it and shook his head: "No...... It's just an ordinary person who lives in an ordinary home, right? ”

In this regard, Miss Kyoko gave up continuing to ask, then glanced at Gao Yuan and motioned for him to come, so Gao Yuan answered the question.

"The man you met this morning, and they were worried that there weren't enough coins, so they should be going to call soon. But today is a working day, most people have to go to work, and they are not at home during the day, so what they are looking for at this time is ......"

"It's someone who is home during the day, and it's likely to answer a strange phone call—"

Hidekan Esuke replied, "It's a housewife!" ”

After saying this, Hidekan Esuke suddenly realized something, and then looked at the two detectives in front of him with an expression of disbelief-

"Could it be that I ran into ...... this morning?"

"That's right, all the clues are connected."

Gao Yuan said.
