When I got home, I mopped the floor and washed the toilet, as if I could go home by myself with a little more work.

My dad was watching the novelty from the side, how could he know that I was out of a weak heart: "I'm afraid the sun didn't come out of the west today, right?" Or did you get kicked in the head by a donkey? It looks like it's hurting a lot. ”

"You said that," I involuntarily increased my horsepower, "I should do more work, I don't always want to lighten the burden on you both." ”

Hearing this, my mother came over and groped along the windowsill I had just wiped: "The work is also perfunctory, and it is all dust." ”

Mom is so fine, I didn't dare to look at her face, so I had to avoid the important and light: "What I educate is to actively correct it in the future." ”

She still had a gloomy face: "Bao Zhun'er has done a shameful thing that will not see the light, I will give you a chance now, I will do it myself, and when I find out, don't blame my subordinates for being ruthless!" ”

"Break my dog's leg," I said for her, "and that's the only way to threaten me all day." ”

"It's good to know, now while your dog's legs are still there, hurry back to the house and sleep!"

As the so-called one thing drops one thing, seeing my mother, like a mouse meets a cat, I have no choice, I can only put down the rag and roll back to the bedroom, the pants have just been taken off halfway, the living room suddenly rings, and then I heard my dad shouting: "Xinxin, the study committee urges you to hand in your homework!" ”

I was so scared that I almost didn't stand still and fell to the ground, and in the middle of the night, Xia Yu didn't think of a suitable excuse!

So I hurriedly put on my pants to answer the phone, and my father seemed to have a lot of opinions: "What's the matter, I don't study well in school, and I haven't finished my homework, so people call me in the middle of the night to urge." ”

I couldn't argue: "Don't listen to her nonsense, this person is not mentally normal." ”

I picked up the phone after my dad left: "Sister, who said I didn't finish my homework?" ”

Xia Yu said in a high-pitched tone: "Who said that?" Who is so bad? It's not true! ”

I want to see how long she can act: "What do you say? ”

She pretended to be innocent: "I don't know! ”

"Oh," I said, "and no one told me to turn in my homework." ”

"That's right."

"Bye-bye!"

"Hey," she laughed, "don't don't, blame me for being talkative." ”

"It's pretty much the same," I was complacent, "what does Detective Xia do at night?" ”

"Detective?" She chirped, "That's a pretty good word." ”

"It's just flattery, you don't take it seriously."

"Cut, who is rare."

"Gee," I stretched on the couch, "and it looks like you're not serious, so I'll tell you an interesting story." ”

"Yes, listen up."

"Speaking of which, it's always interesting," I patted my thigh and shook my head, "As the saying goes, people have been panicking in the past two days, and thieves are rampant." If Yujun asks about today's affairs, stay in the Ming Dynasty to go to school! ”

"Nonsense, it's all about it, you still don't say it!"

"I'll tell you right away, as the old saying goes, you can't eat hot tofu in a hurry, so you have to have a set poem to blend the atmosphere first."

Immediately afterwards, he confessed: "Anyway, I just went up to the second floor today, and at the corner of the stairs, I was hit by a construction worker who came down from the third floor and almost rolled down. Although Xu Hao saw that his face was familiar, he only blamed that he didn't react at that time. When I went home just now, he told me that he was bullied by three thugs on the court before, and that person was one of them, and you said that the world is not small. ”

I couldn't hear it on the other end of the phone for a long time, and I thought she was bored and hung up.

"Hey, aren't you there?"

Xia Yu's voice suddenly jumped out again: "How can you be sure that person is a construction worker?" ”

I didn't hesitate: "Because I'm wearing a hard hat." ”

"Then let me ask you, in your opinion, what is the difference between ordinary people and construction workers?"

"Where?"

"A hard hat!"

No.119

Xia Yu said to me: "Fool, you passed by the thief today, maybe the Walkman you have been looking forward to all night is on him." ”

I was shocked: "What do you mean by that?" ”

It took her a long time to explain the whole thing to me, and on two occasions she could be heard clearly stopping to drink.

From the beginning of the case, she has been thinking about a key question, that is, the nature of the theft gang, is it committed by the school personnel or the outside school?

This is a very important question, and if we compare this incident to a complex river, it is the source of everything, and all the clues finally converge here like tributaries, and only by clarifying this can we sort out the context of the whole thing.

Unfortunately, we were on the wrong path from the start.

The entire library can be entered by two kinds of people, teachers and students and construction workers. The ability to take the package up close without attracting attention is a common sense that the thief must be dressed as a student, and only then will the thief be more assured. From this point of view, the likelihood of a construction worker is extremely low.

The idea of either/or traps us in it.

However, through her observations, she found that there was no uniform dress code for the construction workers entering and leaving the library, and some even wore civilian clothes with yellow hard hats on each head.

So she began to consider whether there was a third possibility, but she always felt that a crucial link was missing in the middle, and she suddenly realized what happened to Xu Hao just now, and finally found the last clue to untie this knot.

We simply and stubbornly believe that the gang of thieves has a secret location to hide the stolen packages. But they didn't expect that this location could also change their identities.

That's the important link that is missing!

With this link, thieves can be the third possibility, excluding teachers, students, and construction workers. Suppose they somehow get a few hard hats from a worker, they can swagger into the library dressed as a construction worker, and if they want to, change into a few deliberately soiled clothes to be more subtle.

Then, in a place unknown to us, we took off our hats and clothes and kept them, as if they were classmates from Xi, and after stealing them, we threw the worthless items in a secret place, and then left as a worker.

So repeatedly, who would have thought that in the quiet library, a costume show was being staged in a certain corner.

"Is it really that simple?"

"It's as simple as that, we're just confused by superficial appearances and preconceived ideas. The correct and important clue is ignored, but once it is grasped, everything that happens in the future can be used as evidence for reverse reasoning. The modus operandi of this gang now seems to be really clumsy, and even full of loopholes is a bit ridiculous. I suspect that there may have been a few times when they happened to be bumped into by some classmates or workers while they were busy changing their clothes, but who would pay special attention to the behavior of strangers? ”

"The most mundane crime is often the most mysterious, because you don't see anything new or unique about it. If the thief is a few school students with crooked thoughts, it is a needle in a haystack to solve it. ”

I was annoyed, "So what are we going to do next?" ”

"Find that mysterious location, and then just wait for the rabbit."

I regret greatly: "Today's trouble will definitely arouse the vigilance of that gang, and it is hard to say whether it will appear in the future." ”

Xia Yu said, "Greed is human nature, and the possibility of committing crimes against the wind is not impossible, give me some time, let me think about it, and give you the answer tomorrow." ”
