Who Is The Killer In 'One Of Us Is Back'?

“Get away from me,” I hissed, gripping the knife tighter. His gaze flicked down to the blade, then back to me, a slow, amused smile curving his lips. “A knife?” he said softly, tilting his head. “Are you perhaps flirting with me?” I gritted my teeth. The asshole was enjoying this — every fucking second of it. ⫘⫘⫘⫘⫘⫘ When Leah got home early from work, she was hoping for one thing — to fix what was left of her relationship with Daniel. Instead, she walked in on him in the arms of another woman. Heartbroken and humiliated, she stormed out, blind with tears… and straight into the path of an oncoming car. But death wasn’t the end for Leah. No! Death was actually the beginning.

The prettiest girl in our class, Mandy Smith, died unexpectedly in our dorm. When the police took statements, my two other roommates and I pleaded guilty. I took out Mandy’s love letter to my boyfriend. “I killed her because she was seducing my boyfriend.” Anna Anderson took out a purchase history for cyanide. “I killed her because she snatched my overseas studies spot from me.” Fiona Lee took out an expulsion letter. “I killed her because she reported me for cheating.” All three of us hated Mandy. However, the police found that all of us had alibis during Mandy’s time of death. The counselor also asked us to stop lying. However, the three of us sneered. “Whether you believe it or not, one of us is the murderer.”

I quit and dipped. City threw a parade. Only Jenna Blake—my oh-so-gifted junior who claimed she could "see through killers' eyes"—lost it. At her celebration banquet, she went full drama queen: "I owe everything to Kate Mercer. Please, bring her back!" I laughed. Cold. Not happening. Last time around, I was the hotshot detective. But every clue I found? She dropped it first like she read my mind. People started saying I was washed. So I went all in—three months, no sleep, cracked a massive trafficking ring. Led the raid myself. She beat me there. Again. Place was cleaned out. Boom. She's the city's golden girl. I'm the clown with no game. Pressure got ugly. My head snapped. I died chasing the last scumbag. Then—bam. I woke up. Same day. Raid morning. Round two.

During the holiday, I took my whole family on a trip. Just as we were about to head back, more than ten police cars surrounded us at the guesthouse. The police showed a video. In it, under surveillance cameras, I drove to a forest near a popular tourist town the day before and dumped a corpse. Even more frightening, there was a strange woman sitting in the car. After throwing away the body, the two of us immediately engaged in intimate acts inside the car. Hannah Walker slapped me hard across the face. "No wonder you insisted on going to that tourist town to buy snacks for us—you were using it as an excuse to go on a date! "After doing something so inhumane, you still had the nerve to do such filthy things in the car?" However, yesterday, I had clearly gone to the town alone to buy snacks and returned. There was no such horrifying experience at all. Without another word, the police opened the trunk. When the searchlight swept across it, it was filled with bloodstains from the victim's body. In the corner, they also found the murder weapon with my fingerprints on it. I had no way to defend myself. I fell from being a rocket engineer, a hero in the country's aerospace field, to a death row prisoner. Due to the severity of the case, I was sent to the execution ground in less than a month. My parents and child, who had been on the trip with me, were blocked at the guesthouse by the victim's family and beaten to death. However, even as reality dawned on me, I still did not understand what had happened that day. When I opened my eyes again, I was back at the moment I was about to leave to buy snacks.

Fifteen years ago, my parents-in-law were cut into pieces. My wife and I spent years searching for the killer. One day, I came back from the market and found that the neighbor’s family had been murdered in the same way. At the crime scene, I saw the neighbor’s face in the mirror. I rushed out and chased him. I was just about to catch him when my wife stopped and handcuffed me with her own hands. “Drop the act. You’re the killer!”
