How Do Modern Japanese Mystery Novels Reinvent Classic Whodunits?

As the news broadcast reported a random serial killing near my residential complex, I knew—I had been reborn once again. In my first life, my husband insisted on going out in the middle of a snowstorm to buy weapons for self-defense. I locked every door and window, waiting at home, anxiety clawing at my chest. I never imagined the killer could pick locks. Before I could even react, a blade plunged into me, and I died on the couch. In my second life, I didn't hesitate. I hid in a concealed storage room, holding my breath. But the door was still pulled open. A man wearing a rabbit mask stared straight at me. "Found you," he said. In my third life, I ran to the police station. I rushed inside and told the officer on duty that the killings weren't random—that the murderer was coming for me. They looked at me like I'd lost my mind. Then my husband arrived in a hurry and took me away. But the moment we reached our front door, a heavy hammer smashed into the back of my head. Through the blinding pain, I forced my eyes open, but I never saw who killed me. Now, staring at the grave expression on the news anchor's face, agony surged through every inch of my body. Rebirth isn't a reset. The damage accumulates—and sooner or later, it will torture me to death. Without hesitation, I walked into the kitchen and set a pot of oil to heat. And I waited… for the moment the lock began to turn.

Alice Warren was the daughter of two famous murderers. Her fate, which was full of bad luck, finally met its end when the Le Blancs adopted her.

Alice was already contented with her life, but all of her beliefs and luck crumbled down when she entered Saint Clair Academy, and the series of accidents and deaths started again. Of course, it did not help that an irritating genius artist, Thomas Saint Clair, was always at her tail. Now that the number of dead bodies increased, Alice had to investigate whether the accidents were just lousy luck full of coincidence or carefully planned-out murders.

I am a doctor. One day, I come across a weird patient when I am on duty. The first thing she says when she sees me isn't that she feels unwell somewhere. Instead, she says something hair-raising. "Dr. Cantrell, your girlfriend is a murderer." "What nonsense are you spouting?" I shoot back with widened eyes and shoot up from my chair. I feel offended. She calmly says, "She won't be home tonight because she needs to deal with the body. You will know whether what I say is true by tonight."
