[Chapter 30, Bloody Maple Leaf 11-The Secret of Shoes]

The cleaner aunt quickly rummaged through the entire trash can and said to Xiao Lou: "Teacher, your ID is not here?"

Xiao Lou smiled and said, "Excuse me, I'll look for it carefully when I go back. Maybe I didn't throw it away."

The enthusiastic aunt said: "Then you look for it again, and I will keep an eye on it for you. If you find it in the trash can, I will send it to the lost and found office of the school."

Xiao Lou nodded: "Okay, thank you, Auntie."

He winked at Yu Hanjiang. Yu Hanjiang understood, took his shoes and turned around to leave with Xiao Lou.

The aunt looked at their backs in confusion, probably thinking - why did the teacher take away the shoes found in the trash can?

It was class time at this time, and there was no one on the playground.

The two came to the corner of the playground, and Yu Hanjiang knelt down to carefully examine the evidence.

This is a very common pair of white canvas shoes, the same style as the shoes Ying Xiaoya was wearing when she died. The soles have cross diagonal lines, which will form special footprints when stepped on the ground. The edges of the shoes are very obvious trademarks.

Xiao Lou looked at the shoes thoughtfully: "I saw many students wearing this brand of shoes at school. It should be a popular brand. This pair of shoes was very new, but they were thrown away. The murderer obviously wanted to destroy the evidence...

Captain Yu, who do you think the owner of these shoes might be?"

Yu Hanjiang carefully checked the shoes inside and out, and said: "If the murderer happened to have feet of size 37, it would not be strange to buy a pair of these popular canvas shoes. She could keep the shoes, there is no need to throw them into the trash can.

There is only one reason why the murderer must get rid of these shoes - her feet are not the same size as Ying Xiaoya, and these shoes are not suitable for her. Once discovered, it will easily arouse suspicion. "

Xiao Lou nodded in agreement: "In other words, the murderer bought this pair of shoes of the same style just to wear them temporarily and faked the footprints on the rooftop to make people mistakenly think that all the footprints on the rooftop belong to Ying Xiaoya alone. Okay

It is believed that Ying Xiaoya committed suicide by jumping off the building. The murderer had long paid attention to Ying Xiaoya's shoes and had planned to kill people on the rooftop - it seems that he had planned it for a long time."

"Well, that's why she had to get rid of the evidence." Yu Hanjiang frowned and observed the shoes. After a moment, he said: "I think women are more likely to commit crimes."

Xiao Lou looked at him doubtfully: "Why not a male?"

Yu Hanjiang analyzed in detail: "This is a typical crime committed by an acquaintance. Ying Xiaoya went from the classroom of Class 3 (3) of high school to Xingzhi Building through the sky corridor, and then climbed up to the seventh floor from the surveillance blind corner. This journey is not short.

, if she is taken away by force, the whole process will not be silent, once she screams or resists, the surrounding classes will hear it."

Xiao Lou echoed: "But Ying Xiaoya was very quiet from beginning to end. She didn't know the process of falling from the building. Obviously, she followed the murderer to the rooftop voluntarily."

Yu Hanjiang turned back to look at Xiao Lou and said: "If the murderer is a man, wearing unfitting size 37 women's shoes will definitely arouse Ying Xiaoya's alertness and suspicion. Besides, the murderer doesn't have time to put a pair of shoes on the rooftop to change temporarily.

, once the other person leans over to change his shoes, Ying Xiaoya will notice something is wrong and run away or call for help. Therefore, the murderer should put on these shoes directly to find Ying Xiaoya. "

Men's feet are usually above size 40. Can't fit into canvas shoes of size 37 at all. Wearing them on tiptoe or as slippers will look very strange. If you meet someone along the way, just say no.

Cleared up. Besides, if a man came to Ying Xiaoya wearing the same canvas shoes in size 37, she would definitely be able to sense something was wrong and would not foolishly follow him to the rooftop.

Unless it's a woman.

If the other party's feet are size 35 or 36, they can easily put on shoes of size 37. As long as you put some paper towels in the heels and tighten the shoelaces, the shoes will not fall off easily. Or if they are size 38, they can also squeeze in.

It's so tight that I can barely fit into size 37 shoes, but my feet will be uncomfortable, but if I wear them for a short period of time, I can completely ignore this.

If your feet are slightly small or slightly large, it’s hard to tell that these shoes are inappropriate. In addition, this kind of shoes is very common and many people in the school wear them. Female teachers and female classmates wear this brand of shoes. Ying Xiaoya will not know how to wear them for a while.

over thinking.

Xiao Lou lowered his head and thought for a while, then said: "If a woman commits the crime... Yi Ru, I remember that she is half a head shorter than Ying Xiaoya, and her feet should be about the same size. She wears the same shoes as Ying Xiaoya, and

It’s not easy to attract attention.”

He paused and then analyzed: "And Yi Ru's confession is very one-sided. She and Ying Xiaoya returned to the classroom at that time. What happened now has no evidence. She said she went to the canteen to buy potato chips, and the owner of the canteen did see her.

Pass her... But what if they went to the rooftop first, and she pushed Ying Xiaoya downstairs, then ran to buy potato chips, and then came back and pretended to witness Ying Xiaoya falling from the building?"

When Yu Hanjiang heard this, he looked up at the rooftop in the distance, then looked at the canteen and the location where Ying Xiaoya fell. He quickly came to a conclusion, shook his head and said, "It's not Yi Ru, there's not enough time."

After all, Xiao Lou is just a theoretical analysis, and Yu Hanjiang is more experienced in estimating the actual time of the crime.

He followed Captain Yu's gaze and looked over - Xingzhi Building is seven stories high. Ying Xiaoya fell from the top of the building. The canteen is far away from Xingzhi Building. If Yi Ru pushed Ying Xiaoya downstairs first

, then went to the canteen to buy potato chips, then returned downstairs and pretended to witness the tragedy of his best friend falling from the building. This time was indeed very rushed.

Xiao Lou remembered yesterday's crime scene. When the police asked Yi Ru, she answered intermittently. However, she was not out of breath after strenuous exercise - her breathing was relatively steady.

There is no elevator in the school. It is difficult for Yi Ru to run up to the seventh floor, push her best friend downstairs, run down to the canteen to buy potato chips, and run back downstairs to pretend to pass by in such a short time. Unless she has the speed of an Olympic long-distance running champion.

And I won’t be out of breath even if I run several kilometers continuously.

Xiao Lou overturned his analysis and said: "It seems that Yi Ru can also be ruled out. There is indeed not enough time to commit the crime. She bought potato chips, and the owner of the canteen can provide her with an alibi."

Yu Hanjiang reminded: "We should focus on female teachers."

Carrying a pair of shoes into the teaching building was too ambitious. Yu Hanjiang thought about it and stopped by the canteen to ask for a paper bag to put the shoes in. On top of it, he put the homework book he used to draw the school map on. It looked like he was carrying a bag of homework.

Book.

The two returned to the teaching building.

The chemistry teacher of Class 3, Grade 3, was taken away by the police. The students in Class 3 were in panic. Everyone was restless and had no intention of attending class. However, since the second period happened to be a Chinese class, the class teacher came to the classroom to maintain order and arranged a lesson.

The students did not dare to talk nonsense during the essay question, and the classroom was surprisingly quiet.

There is no obvious abnormality among the three students, Yu Hui, Xie Xinghe, and Yi Ru.

Xie Xinghe lowered his head, looked serious, and moved his pen as fast as he could. He seemed to have opened up his mind and wrote a whole page in the composition text. Yu Hui scratched his head frantically, as if he didn't know what to write. Yi Ru bit the penholder with a grimace.

, obviously can’t write it either.

The essay topic assigned by the teacher is "Pursuit", which is really a headache.

Yu Hanjiang observed for a moment and found that there was no movement in the classroom, so he said: "There should be no new clues in the classroom for the time being. Why don't we check first to see if other teachers were in class when the crime occurred yesterday."

High school teachers not only teach one class, but if they are not the head teacher, most teachers have to teach two classes. Otherwise, the workload is not enough and points will be deducted during the final assessment. Yesterday, Ying Xiaoya’s accident happened in the fourth period. If this

If a certain teacher has a class in another class and is in class, the suspicion can be completely eliminated.

The timetable posted in the classroom only lists subjects such as Chinese and Chemistry, and does not include the name of the teacher. The teacher's own timetable only lists the class he teaches and the class time.

Xiao Lou thought about it carefully and said: "The teachers for these four courses, English, Physics, Chemistry, and Biology, are all women. They are all between 1.6 and 1.7 meters tall and can wear shoes of size 37."

.Except for the chemistry teacher, if the other three people had classes in the fourth period yesterday, we can go to the office to check their class schedules."

Yu Hanjiang said: "We also need to go to the Chinese language office. There is a female teacher who needs our attention."

Xiao Lou was stunned for a moment, then quickly realized: "You mean, the Chinese teacher who suddenly barged in when the head teacher was talking to Ying Xiaoya? She is also a woman, and may also have the possibility of committing a crime?"

Yu Hanjiang looked serious and whispered: "This teacher came by chance. At that time, Ying Xiaoya should have told the reason for the decline in her grades. This reason was very critical and may have directly led to her death. Unfortunately, she was planning to

When she was speaking, an outsider came in and interrupted her."

Xiao Lou recalled the scene at that time and immediately agreed: "Yes, the timing of her coming in was indeed very clever."

Ying Xiaoya was about to say, "My grades have dropped during this period, actually because..." At this moment, the young female teacher opened the door and came in, and Ying Xiaoya immediately shut up and stopped talking.

This teacher is probably related to Ying Xiaoya's falling case, and she came in deliberately to interrupt.

But it is also possible that this was just a "plot-promoting figure" arranged by the secret room - if she had not come in at that time, once Ying Xiaoya told the truth, nothing would have happened after that.

But it’s never wrong to check it out.

They cannot let go of anyone who is suspected.

[Chapter 31, Bloody Maple Leaf 12-Major Clues]

In the morning, there were many people in the teacher's office, so it was not convenient for inspection. The two of them waited patiently for the opportunity.

Soon it was noon.

Xiao Lou and Yu Hanjiang came to the canteen again.

Yesterday, Xiao Lou ate two meals of instant noodles in a row, and now he lost his appetite when he saw instant noodles. Yu Hanjiang took a bowl of instant noodles with a calm expression.

The owner of the canteen knew them and asked curiously: "Why do these two teachers keep eating instant noodles?"

Xiao Lou smiled bitterly and said: "We are both single. We are too far away from home and don't want to go out to eat. Let's make do with instant noodles."

The boss kindly said: "You can also try the self-heating hot pot. Can you afford to eat instant noodles every day?"

Xiao Lou was startled: "Is there still this thing?"

The boss brought a bowl over and introduced with a smile: "Lazy hot pot, the bottom is made of chemical materials that can generate heat. When water is poured in, it will boil automatically. The upper layer is cooked with hot pot powder, vegetables, and beef. It will be cooked in ten minutes.

Already."

Xiao Lou rarely eats this kind of fast food and doesn't know the existence of "lazy people cooking hot pot". But when the shop owner said this, he suddenly became interested and asked: "How much does it cost?"

Shopkeeper: "Two copies of 1,000 gold coins."

Yu Hanjiang turned to look at Xiao Lou, with expectation in his eyes.

Xiao Lou touched the 14 gold coins in his pocket, gritted his teeth and said, "Then buy two copies."

He really didn't want to eat the third meal of instant noodles.

Don't know that firewood and rice are expensive. They have 17 gold coins, and at the rate of spending 2 to 3 gold coins a day, they can only stay in this secret room for 5 days.

It was already the second day, and the secret of Maple Grove had not yet been solved, and the owner of the shoes had not been found. They had to hurry up, otherwise, if the case continued to drag on, they would have to go hungry to solve the case.

Not to mention, they have no place to take a shower and have to sleep in the hard corridor...
To be continued...
