It was another sunny day, and Qin Si accompanied Yan'er to wander the streets. The streets are always full of people, and Qin Si has always wanted to understand why the locals don't have to go to work when they are at ease all day long?

Just as the two of them walked to the door of an antique shop, the little guy in the store suddenly ran out screaming.

"Murder...... Fast... Come on, people......"

Homicide? Qin Si hurriedly squeezed into the crowd to watch the excitement. Who is so bold to kill people on the street, now there is a good show to watch!

"Sister Sisi, let's go......"

"Don't worry, don't worry, I've never seen a murderer, take a look first, don't worry."

"Boss, boss, what's wrong with you!"

I saw the little guy kneeling in front of a chubby man, crying profusely, and there were three men in the room who were at a loss.

"Hmph, I don't have to entangle with you so much, I have to rush home to run errands." A big man with a strong body said impatiently.

"You can't go, you have to wait for the people from the government to come, you can't go!"

"Get out of here, what are you, dare to stop Uncle Ben!" The strong man pushed the small guy away and prepared to rush out of the door.

Seeing that the man was about to escape, Qin Si suddenly rushed into the house and stopped in front of him.

"Wait, you're a suspect now, and if you're gone, you'll prove that you have a ghost in your heart!"

"Whose yellow-haired girl are you, let me leave quickly."

"You don't care who I am, anyway, you must not leave the scene until the people from the government come!" Qin Si's sense of justice surged out instantly, and she felt that she was now Conan's incarnation, the messenger of justice.

When the saber was rattling, the people from the government arrived in time.

"Come on, come on, let go. The government handles the case, and idlers are exempted, who reported the case, come and tell me. A head catcher who looked at the hanging man sat down on the chair with impatience on his face.

"Official, I reported the case, and I am a little guy in our store. My lord was fine, but who knew that he would suddenly die here...."

"Are these people suspects?"

"No, this woman came forward to stop her, and these three are the suspects."

"Boy, keep your mouth clean, who do you say is the suspect!" The strong man looked at him with an annoyed expression.

"Then this woman, please go back first, and leave it to us here. Hurry up, hurry up, go away! ”

"Don't be an official, the little woman also knows a thing or two about handling cases, just let me see if it's okay here, maybe I can help with anything."

"Girl, do you know that disturbing the case is going to go to the prison cell, I think you should leave quickly. Someone ..... coming."

"Official, you can't say that."

At the critical moment, it is still necessary for Yan'er to make a move. She walked up to the headcatcher and showed him the waist tag on his body.

"Wang...."

The originally impatient official saw the waist card and was so frightened that he stammered.

"Princess.... I don't know that the princess is here, so I beg your pardon.... Ah, sin.... Take a look... Stand!! ”

"Ah, he's a princess!"

Watching the lively people with a burst of excitement,

"It turns out that she is the princess, and I saw the real person today."

"The official is polite, this is my sister, can the official give a convenience, just let her watch you handle the case by the side?"

"Of course." The speed at which the head catcher changes his face is also as fast as flying. Yan'er winked at Qin Si, and both of them secretly covered their mouths and smiled.

It was the first time I had seen the scene of the crime, and this tension made Qin Si extremely excited.

She crouched next to the corpse and looked at it, and the dagger stabbed into the abdomen caused excessive bleeding, a very simple murder method. You can see it at a glance.

If this is placed in modern times, it will be understood by taking a fingerprint, but now there is no such condition at all... Wait, Qin Si noticed a detail, there really seemed to be a black thing on the handle of this knife.

This one...... She looked closer, and it was a fingerprint!

Although it is not very clear, there are some blood stains on it, so it forms a very unique fingerprint.

Scold..... What a coincidence, Qin Si's eyes rolled, and he immediately had an idea.

"Official, can you help me pass on a message?"

Yan'er sat quietly on the side, secretly observing the three suspects. One was a weak scholar-like man, sitting cramped and restless at the edge of a chair, the second was a strong man who was always arguing to leave, and the rest of the man, who looked like a businessman in his thirties, sat calmly next to him, only occasionally poking his head out of the door.

It didn't take long for the girl to come running over sweating profusely.

"Sister, I'm here!"

"Okay, come in!" Qin Si waved his hand happily at the girl.

"Girl, you are..."

"Don't worry, I'll find the culprit!"

She whispered to her, and the girl immediately understood what she meant.

"Official, can I talk to them?"

"Yes, girl, please."

"Master Xie."

Qin Si walked around in front of them with his arms crossed, and in each episode of Conan, there would be several suspects left at the scene, and the murderer was often the one who was the least like. So she decided to start with a scholar first.

"Little brother, what are you doing here today?"

"Oh, girl, I'm just here to be a thing, the family is in urgent need of money, and the boss said that this jade bead of my family can give me a good price."

"Oh? Can you show me your jade beads? ”

"The beads... It's gone! The scholar looked anxious, "It was originally placed on the table, but it was gone in the blink of an eye."

"Have you looked for it? Did you fall somewhere? ”

"I've found it, I've found it, but I haven't found it!" The scholar was so anxious that he was sweating, and it seemed that this thing was really important to him.

"Okay, thank you for your answer."

She turned to the second person, the strong man, who was the most suspicious. I always wanted to leave, and I was disrespectful, I don't know if he was because of his weak heart, or if he was pretending.

"What about you? What for? ”

"What's the matter with you, I don't care who you are, I didn't kill anyone anyway. If you don't let me out again, I'm welcome! The strong man looked at her viciously, which made her feel unhappy.

Hum... I'll find out if there was any murder. Qin Si glared at him, then turned to look at the third person.

Only this person has been calm from the beginning to the present, and this psychological quality is often a manifestation of concealing the weakness of the heart.

"Dare to ask, what are you doing here today?"

"It's nothing, I'm familiar with the boss, and I'm going to go around today."

"I see, I have looked at you a little familiar since I first came in, and I dare to ask if you are the shopkeeper Liu of Dongjie Buzhuang?"

Qin Si looked at her with a smile, which made him obviously stunned, and then returned to normal.

"Exactly, you.... Know me? The man was stunned.

"Of course, I often go to your house to buy fabrics, but the business is so good that you may not notice me."

"Oh, that's rude. Another day, the girl will go and say hello again, and I will give you preferential treatment. ”

"Yes, then thank you shopkeeper first." Qin Si's eyes sank, she already had the answer in her heart.

"Sister, I've done it all." The girl took the evidence and put it in her hand dignifiedly.

"Okay, sir, I know who the murderer is."

"Really?" Headcatcher was surprised.

"Of course, as long as everyone puts their handprints on this piece of paper, the prisoner will be revealed."

"Someone, prepare ink."

The three of them printed all the fingerprints on their ten fingers, and Qin Si looked at the paper and laughed.

The whole audience can't figure out their heads, can they solve the case by printing a handprint?

"Girl, this ..... Please let the girl make it clear. ”

"Hahaha, there is only one truth! I'm a detective, Qin Si! ”

“……”

The audience was silent.

"Ahem...."Qin Si cleared his throat a little embarrassed.

"Everyone has seen that the shopkeeper died because the dagger was stabbed in the abdomen, and the murder weapon was still left at the scene, so this is the most powerful evidence."

"What do you mean by that?" The headcatcher was a little puzzled.

"I'm here to educate you about something. Please observe your own hands. Everyone's fingers have lines on them, which are called fingerprints, and the fingerprints of each finger are different, and everyone's fingerprints are also different. ”

Watching the lively people, they all took their hands and began to compare.

"Really, really, we're both different."

"It's just that I didn't notice it before!"

"Therefore, everyone's fingerprints are unique, and whoever leaves their fingerprints on the knife is the murderer.

"Yes, the girl has a point. But how can we see the fingerprints on the dagger? ”

"Look, this is the scotch tape we sell in our store, which not only sticks things, but also relies on its stickiness to take a picture of your fingerprints. Look, everyone, this is the fingerprint that the girl just glued off. ”

The girl showed the tape to everyone at the scene, and sure enough, a round fingerprint was clearly displayed on it.

"Now if we compare the fingerprints on the paper, we won't know who the murderer is."

The head catcher took two fingerprint papers and began to compare them one by one, and it didn't take long to find the difference.

"It's .....!"

"It seems that the official already knows the murderer." Qin Si smiled.

"Of course, thank you for your advice. Come on, take down that merchant for me!

"Yes!"

"Why arrest me!" The man refused to confess his guilt unrelentingly,

"I said big brother, you showed your feet at the beginning, so hard that you didn't even notice it?" Qin Si looked at him proudly.

"The boss of the cloth seller on East Street I am talking about is called Wang Yiba, and the name Boss Liu is simply made up, you still believe it, and you want to give me a discount, I said big brother, you still come out to kill people with your IQ."

"Hmph, ridiculous, even if the name is wrong, why do you say that fingerprint is mine." The businessman denied his account with a dead face, and was still struggling senselessly.

"Big brother, you really don't shed tears when you don't see the coffin."

Qin Si took the fingerprints and let him see them, "Please see clearly, the fingerprints of these people are all irregular, only you, you have to have a fingerprint with a very regular circle, and it is very beautiful in a circle, and only you have it." ”

"How impossible!" He grabbed the hands of the scholar and the strong man. Sure enough, only his own fingerprints were unique.

"I mean, if you want to blame it, it's a rare round fingerprint. What a striking feature! Take! ”

The merchant was taken away dejectedly, and Yan'er breathed a sigh of relief.

"Wait, you... Can't go yet. The person Qin Si was referring to was that strong man.

"Why, the murderer has been captured, why can't I leave." The strong man was furious.

"Because, you're a thief!"

Qin Siyi said loudly, "You stole the scholar's jade bead, you are afraid of being discovered, so you have always wanted to escape." ”

"You... Bloody mouth..."He was a little irritable, and his forehead began to sweat.

"If not, would you dare to take your boots off? From the moment I came in, I noticed that you were not comfortable walking, so I concluded that there must be something in your shoes. How about it, dare to take it off? ”

"Take it off! Take off! The crowd next to him also began to coax, and the officers and soldiers next to him came up directly to control him, and took out a white jade bead from his boot.

"Wow.... What a girl is like a god..."

"Yes, yes, it's the same as she said!" The people around spontaneously applauded, and such a beautiful reasoning was really rare.

"Sister Sisi, you are awesome!" Yan'er ran over happily, "I really didn't expect you to solve the case..... It's really exciting. ”

"It's a little meaning, it's a little meaning!" Qin Si rubbed his nose, fortunately, Conan didn't watch hundreds of episodes in vain!

The crowd gradually faded, and the people on the street were still talking about the case, and the woman who decided the case also became a hot spot for everyone's gossip after dinner, which was comparable to a human flesh search.

In one of the rooms of the inn, two people stood in front of the window and looked at the two women on the street. One is suave and the other is lively and cute.

"General, we can't save people."

"I don't have the ability to escape, why should we save him." The man turned, a fierce smile on his face.

"That woman has to investigate carefully."

"General Hui, I have already gone to investigate, and I have not found any suspicious points for the time being."

"Okay, let's investigate, I don't believe it, she appeared out of thin air. Yes, General Sali. ”
