A loophole in the mystery

It happened in 2013, l was studying grade 7
       On that night, the red moon bleeding as it was stabbed by someone. The entire hostel was cursed with silence and dark.  But we didn't care for that. It would be around 30 minutes to midnight, Me and my friend Pranav were playing Pokémon trading card game. We both camouflaged ourselves under the  blanket to escape from warden's eyes. We used torches as our light source because room lamps were offed as per the hostel norms. Suddenly I noticed the shadow of unknown passing the window. I warned my friend to shut down the torches. We both pretend to sleep. With half closed eyes, I tried to figure out the unknown shadow. It stopped in front of the door a while and entered inside our room. I was eagerly waiting for suspense to get reveal. But that was petty. It was him.... Our warden. He was just on patrol. Then we both decided to catch some Zs. In dead of midnight, the barking dog woke me up. With droopy eyes, I lumbered towards the window and looked out. It was Jimmy, our guardian of the hostel.  I saw Jimmy barking Continuously by staring at something. With dazed mind, I woke my friend and asked him to check out. I really didn't know what he thought. In sleepy tone, he replied that it might be a ghost. I was stunned with his reply and simply moved to my bed  without any cross question. Because fear towards ghost is in my blood.
       The next day was Sunday, A day to refuel our soul with fun and happiness. Every Sunday morning, we used to go out for the trekking from our school. That offer was served only for the hostellers. All were asked to assemble sharply at 6:00 a.m. in the ground. Roll call was taken before trekking. They discovered a boy was missing and his name is Idhayan studying grade4. Our chief warden asked the other wardens to look over for the missing boy. After a short while, they found him no where. Everyone was tensed and Panicked. The chief warden questioned us that if anyone knew about him can say to me. But no one stepped forward and all babbled. Because of that trekking was cancelled.
       The rumours floated around the hostel. I heard that he ran away from the hostel because of harsh treatment....he was haunted by the ghost.... He was kidnapped by the workers.....He was murdered. All those rumours created the mystery in his missing. Have you ever experienced watching a detective movies?? It gives some sort of  curiosity to know what happens next and everyone loves that mystery!! Even we have mysteries in our life too. Some are answerable and others may not. I used to read lot of crime stories and watch detective movies. Of all that Sherlock Holmes is my favourite. So me and my friend decided to reveal the mystery.
       We didn't know from where to start. I simply prepared the investigation sketch in back side of my rough note as do the most detectives do in the movies. In a brief period of time. High official of the school management arrived to our hostel. Theirs hustle and bustle showed the seriousness. The management didn't filed any complaint to the police and didn't inform to that boy's parents. But tried it's best to find that boy. And then the day passed.
      The chief warden insisted everyone to go back to their room. But me and my friends remained and hid ourselves behind the tree to know what was going to happen. I noticed the officials were rushing towards the well followed by the police and rescue team. They pulled out the boy's corpse from the well. I saw his body was bloated and skin turned pale that made my heart broken. I found His head was shaved and perfect cut in the veins. Usually the well would be in closed condition and opened only maintenance purpose. The police arrested the old poor watchman for enquiry because he had the keys for that lock and the lock was not broken. There was nothing to do with the watchman. I knew him personally, he is polite and good hearted person. Then the autopsy was done for the further investigation. They said that it was a perfect crime.
         With the disturbed mind, we both went to our room. Later everyone gathered to offer our condolences for his death. From that moment, me and my friend started to seek the murdered. First of all the murder scene occurred in our school campus, so we thought there must be someone who would be the witness for that crime or else they might be the reason for that crime. We surveil on everyone and sorted out the odd one. At last I noticed one boy named Akash, who behaved very strange.....yes!! He was our first suspect. Then we spied on him. We kept an eye on all his activities. I saw him feeling emotionally confused.
           That night, I stirred up in the zero hours to spend a penny. While I was on the way to the lavatory, l heard some husky murmuring voice from the next door. I went close to the door and lent my ears to listen . Then I became acquainted with suspect to be blamed. I couldn't believe my own eyes when I saw the warden named Nagaraj threatening Akash. Unknowingly, I shut the door which disturbed them. He suddenly tilted his head towards the door. What the heck!! He spotted me but actually he didn't, I was over reacting, yeah!! I knew, I was making something out of nothing. What if he noted me??then there would no escape because we didn’t have any evidence against him. My heart pumped fast and skin bled sweat. There was an earthquake in my body. So I sprinted to my room before getting caught.   
     The next day, I explained everything what happened that previous night to Pranav. We planned to collect some evidence against him.  I borrowed the phone from Nagaraj to ring my parents. But actually I got to explore the phone. I went to his recent calls and browsing history. In that he googled something related to " How to escape drug ingestion from post-mortem”. I was totally puzzled. In the absence of his presence, we both went to his room checked out for drugs. After a prolonged search, we came out with some medical certificates mentioning that he was suffering from chronic pain and above that we found the tablets labelled “methadone”. I knew about that drug...I already studied in the newspaper that" Consumption of methadone by the child accidentally lead to death”. But still we couldn't be able to get what had happened exactly. I went to him while he was in the room. He was having coffee. I called out the word - ’murderer’ to get his attention. With terrified face, he dropped the coffee cup. I blamed him for his murder. At first somehow he tried to manage to escape. But I was adamant in my statement and argued for that. At last he accepted his crime with anger. I saw the arrogance in his face. He was over confident that he wouldn't get caught. He said- ‘you have no evidence against me and l will get transfer within this week’.
         He revealed the truth behind the mystery. “That Saturday, Idhayan informed the warden that he was suffering from fever and cold. The warden asked Idhayan to intake  paracetamol tablets from his cupboard. But instead of taking paracetamol, he took methadone. He thought that if we consume more tablets, he would get cured quickly. So he consumed more tablets that killed him. That was later got to know by the warden when Akash reported that Idhayan was lying on the bed without any sense. Then the warden carried Idhayan to his room. He created the scene as Idhayan was taking rest in his room. To escape away from the accidental murder, he planned to throw the body into the  well. So he stole the keys from the old watchman. He knew that he would definitely get caught in the postmodern report. So he studied in detail about the drug and how to escape from that. The methadone will present in the body only for 2 days. It may be present in trace amount in the blood and hair. Thus he shaved Idhayam's head and cut his veins before throwing into the well. He safely disposed the body in the middle of night. He included that he also killed Jimmy”.
          Actually we played a game with him. We heisted the phone from our chief warden and framed in Nagaraj's room to capture video. We handed over this video to our principal to take further necessary action. The next day, police arrested the warden. The police and school management appreciated me and Pranav for our bravery and intelligence.
