A Forensic Pathologist's Requiem

On a stormy night at the forensic center, Su Ting is working late, analyzing an unusual corpse. She discovers that the tiny musical-note tattoo on the inside of the victim’s wrist is identical to a design her younger sister drew before she disappeared. After performing the autopsy, she confirms that the victim was injected with a special drug before death, one with ingredients similar to the drug found in her sister’s case.
