You, a doctor in a small town, lived a solitary life, dedicated to treating the ailments of its residents. Your days were peaceful, if a bit monotonous, until your routine was shattered by a series of chilling events. Over the past few months, corpses began appearing in dark alleys, discovered roughly once a month. The bodies were eerily drained of blood, yet bore no visible wounds. The strange circumstances divided the townsfolk—some whispered of supernatural forces, while others suspected the work of a deranged serial killer. Fear gripped the community.

The police launched an investigation, but their efforts yielded no leads. One peculiar detail emerged, however: the murders always coincided with the night of a full moon. Despite this clue, the authorities remained baffled and, in desperation, sought help from the town's doctors. Given the small population, the burden of this responsibility fell heavily on you.

Determined to uncover the truth, you threw yourself into the case, approaching it with a scientific mindset. You examined the bodies meticulously, looking for logical explanations, while the authorities tried to calm the frightened townsfolk with rational assurances. Yet rumors persisted. Some speculated about witches, curses, demons, or even vampires.

It was late in the evening now, and the town lay quiet under the glow of a full moon. Its pale light illuminated the cobblestone streets, casting long, eerie shadows. You, after finishing another autopsy, sat by your open window, sipping tea. The cool night breeze brushed against your face as you stared up at the moon, lost in thought.

The peaceful moment was suddenly broken by the sound of muttering—quiet and irritable—coming from the sidewalk below. You leaned forward, peering down, and spotted a man. He was dressed impeccably in an expensive suit, but his body language was tense, his movements agitated.

It struck you as strange. No one dared to walk alone at this hour, especially after the recent murders. Suspicion gnawed at you as you watched the man. Who was he? Why was he out so late? As you mulled over the possibilities, you failed to notice that the man had slowed his pace and was now glancing up at you with sharp, assessing eyes.

The man suddenly cleared his throat, snapping you out of your thoughts. Startled, you realized the man was standing just a few meters from your window, his earlier frustration replaced by an unsettling expression of amusement—almost... satisfaction.

"Why aren't you asleep yet, young man?" the stranger asked, his voice smooth and measured as he began to approach.
