The Class Evolution's
Murderman

The grin expands from mike's face, his brown eyes glistening with the full moonlight.

mike and I immediately went back home and gathered everyone to sit in the living room while Mike went on the mission I gave him, through the dark of the night forest.

"are you gathering everyone like this? " Task ma'am may.

"we will soon know the mastermind behind sarah's murder" I replied, smiling triumphantly.

"but don't we know that the culprit is an outsider, even until now the murder weapon has not been found" Serry immediately cut off my conversation.

"it's not really that the killer is among us" I replied confidently.

everyone in the room looked at each other suspiciously.

"first I will take you all to the second floor to show you the weapon used to kill sarah" I said as I walked towards the second floor, everyone following with a serious look.

arriving on the second floor I told everyone to wait in sarah's room, while I immediately went to teacher emi's room and brought a flower pot to sarah's room. I had expected this flower pot to be very heavy, much heavier than usual.

"what are you going to do with that flower pot" asked teacher emi.

"this is a blunt weapon used to attack sarah, you should know it was Emi" I replied briefly.

"Ba..how could I kill sarah, you've checked yourself there's not even a spot of blood on the flower pot" replied Ms. emi frantically.

"well, outside is not there but. "I poured the contents of the flower pot.

"Stone, how can you use pebbles to kill people" Kim said in shock.

"if only one does not hurt anyone but if all these stones are put into plastic and used to hit people about what happened" while grinning I poured all the stones on the floor and rightly I guess there is a plastic with blood stains on the bottom. I immediately pulled the plastic with the blood spots and showed it to everyone. everyone was shocked to see it.

"how are you going to explain this teacher Emi's mom, or rather I call teacher Lee emi the older brother of Lee sharon the student who killed himself a few months ago."

It looks like teacher emi is just silent listening to my analysis.

"you seemed to have deliberately collected gravel this afternoon when we were all resting, and then you put it in plastic and killed sarah when we all went back to the room after dinner. finish attacking sarah you open the window and tie the rope that goes down as if the attack is the act of an outsider then go back to the room and throw all the land in the flower pot through the window, after that fill the pot with gravel and hide the plastic with blood spots at the bottom"

mom started to sing a cynical smile and started talking.

"I killed Sarah, but she deserves all this. HE KILLED SHARON, MY BROTHER!!! though Sharon was a very good child, she was very popular and never hurt anyone else but sarah ruthlessly killed my sister by pushing her from the 3rd floor. is it worth that such a person is still given a chance to live!!?? "

"But if you're sure that Sarah did, why not report to the police, why would you commit a murder like this? " Tanya kim.

"Police!!! can they face the family of sarah who is a wealthy businessman.all can be bought even a truth, so let my bloodied hands to take this revenge!!" It looks like Emi is laughing while she is happy, I don't know what she is feeling right now.

"Are you really sure Sarah killed sharon?? because it looks like you are being used by someone for personal gain, because there is still one more thing" I replied.

"The killer is still one more person" suddenly my words made everyone look back at each other.

"what do you mean there's a murderer again, isn't it clear that Sarah died from a blunt force wound to her head" now it's ma'am may the housekeeper's turn to speak.

"No, actually what caused Sarah's death was not just a blunt force wound on her head. But more precisely because of the poison"

"Poisons?? " kim repeated my words as if he were still not convinced.

"Dad, don't you feel weird about Sarah's death position sitting like this?"

"it's possible that Sarah was sleeping on the chair so that she died in a state of still sniffling" kim began to pay attention to Sarah's position.

"No way, the time is too short if sarah falls asleep so soundly that no one enters the room. generally, if someone sees someone entering his room suddenly, he will stand or scream if someone attacks. but until Sarah's body is found we don't even hear Sarah's screams at all"

"so you're saying that before you attacked Sarah, she was already dying from poison? " question kim reassured.

"really, plus when I first found Sarah's corpse her skin looked reddish like cherries, when if she had died from blood loss it should have been paler" I replied.

"But how sarah can be poisoned while we eat and drink together, if the poison is in our food and drinks will also be exposed to the effects of poison" now it's Serry's turn to speak up.

"No, the poison is not in food or drink!"

"Well how sarah can be poisoned if the poison is not in food or drink" now it's Mr. Hans' turn to ask.

"The poison is not in food or drink but in the nail polish used by sarah" everyone again surprised by my statement.

"But how can nail polish cause poisoning" asked Kim.

"indeed it won't be for us but what if sarah has a unique hobby that is biting the fingernails.you can check it yourself at some fingernail tips sarah's fingers are uneven there are bite marks"

the curious Kim immediately approached Sarah's corpse and examined sarah's fingernails, kim was surprised.it seemed like he also found a bite mark on the tip of sarah's fingernails.

"There were actually bite marks on some fingertips of sarah's fingernails" Kim spoke trying to convince everyone in the room.

"But how can you be sure that the poison is in sarah's nail polish?" now it was Serry's turn to ask curiously.

"from what I see it looks like the nail polish that Sarah carries is the same as Serry's, but when you smell it these two nail polishes have different scents, they're different, in the nail polish sarah there is a very distinctive almond aroma that is one of the characteristics of cyanide poison and the smell of almonds is also smelled from the lips of sarah, while in nail polish Serry only smelled the fragrance of herbal plants.

In addition, when we finished dinner whether you do not realize Sarah walked a little staggering to prove that the cyanide poison has begun to show side effects, he said, but because the toxins contained in nail polish are swallowed little by little it does not directly cause death but only side effects such as dizziness and muscle weakness."

"so who put the poison in sarah's nail polish? " question kim was curious.
