On a normal Monday morning, students came to the classroom as usual, waiting for the teacher to come to the self-study class.

The team leader on duty looked at the place where the clock hung above the blackboard at the back of the classroom, wanting to see how long it was before class.

"Ahh

"What's wrong?" A classmate asked in surprise.

"Look, everyone, the clock is gone." He said.

The students will see the past. "Why are the clocks gone?" The students were surprised to ask.

The quartz clock is exquisitely made, and it is one of the five clocks donated to the county education bureau by caring overseas Chinese. The county education bureau awarded the school as a prize, and then the school awarded the prize to the class, because the table tennis team led by Lin Liu won the first prize in the county-wide competition. This clock is a symbol of honor and has a lot of significance. A classmate invited the head teacher, and the head teacher frowned and said loudly in the class: "Whoever took it, please admit it automatically, and tell me in private, so that you can be exempted from punishment, otherwise you will be severely punished if you find out!" "But for three whole days no one admitted it. The head teacher asked Huzi with the key to interrogate, but to no avail. The good clocks disappeared in the classroom, and no one admitted that the people who stole the clocks were too rampant and had to be strictly investigated, and the head teacher made up his mind. The head teacher named and set up a five-person crime-solving team headed by Lin Liu.

Lin Liu organized a five-person discussion meeting to solve the case, and Lin Liu analyzed: "The doors and windows are not damaged, the door locks are intact, and the things are stolen, someone should have opened the lock and entered." It is also impossible for a classmate with a key to take it, so it is too obvious. "But who has a key?" said the disciplinary commissioner. "There may be two situations, one is that someone has a key, and someone with lockpicking expertise did it." Lin Liu said. "The person who stole the clock and watch was not necessarily a classmate in our class, it may be from an out-of-school class, or it may be someone from outside the school." Said the deputy squad leader. "Yes, the person who took the clock must have liked it very much, or needed it very much, and must have coveted our clock for a long time, otherwise he would not have taken the risk of doing it, which is illegal." Lin Liu said, "I have an idea, there is a watch seller in the town, and the person who steals the watch may go there to see the watch, let's visit the boss." Everyone agreed.

Linliu is very famous, of course, the owner of the store has heard of Linliu, and when he saw Linliu visiting, the boss received him very warmly. The boss heard the purpose of Linliu and several other people's visits, and provided information truthfully. He said: "In the previous paragraph, there was indeed a young man who came to consult the quartz clock, and he came several times in a row, saying that he wanted to give it to his girlfriend, but the price was too high, and he was not willing to buy it. A young man with a black mole on the side of his nose, which seems to be from a village in the east. ”

Lin Liu led everyone to the eastern village, and soon inquired about the young man's home. Knocking on the dilapidated door, the door was opened by the young man with a black mole on the left side of his nose, and the young man was very alarmed. Lin Liu asked directly: "Excuse me, do you sell quartz clocks, our class just needs a quartz clock!" The young man knew that the matter had been revealed, and he trembled with fright and said, "I took your quartz clock, please don't report it." I also have no choice but to get married, and my girlfriend has to buy a brand-name quartz clock, but the family is too poor...... "Lin Liu looked at his family's few simple houses and sympathized with the young man. "Give us back the clock, we will never report the crime, I hope you will be a good person in the future." "Good...... Okay, by all means...... Certain! The black mole youth said.

Although the case is not big, it is a mystery case, and Lin Liu's young age to solve the case is full of wisdom, which is really surprising.

The quartz clock returned to the classroom, and the students applauded!
