The fog clung thick to the cobblestone streets, muffling footsteps and whispers alike. A lone streetlamp flickered weakly, casting shadows that danced like specters. Beneath its glow lay a body, pale and still, a crimson stain spreading slowly. A gloved hand reached down, plucking a silver locket from the victim’s stiff fingers. The clock tower chimed midnight, its mournful tones echoing through the empty, rain-slicked alleyways. A detective’s trench coat billowed as he knelt, examining the wound with practiced, unflinching precision. The locket snapped open, revealing a faded photograph of a woman with haunted eyes. A single word was scrawled in blood beside the body: *Remember.* The detective’s jaw tightened, his breath visible in the cold, unforgiving air. Somewhere in the distance, a cat yowled, its cry slicing through the silence like a knife.
