Chasing the Evil to the Bone

As a forensic scientist with the Special Cases Unit, I can touch a corpse to trigger a "death replay." This time, in the victim's memory, the murderer was wearing my wedding ring. Trembling, I looked at my left hand—the ring was missing. The captain suddenly informed: "The DNA results are out, the murderer has your genetic marker." I rushed to the archives to look up the erased memories of my childhood, only to find that the door lock had been changed. The last line of small print on the newly posted rules on the wall read: "Su Wan, stop checking."
