Rain hammered the cobblestones as Detective Mara entered the dimly lit manor, her coat dripping with chilled mist of sorrow. A shattered crystal vase lay beside the grand staircase, its shards glinting like tiny, murderous constellations under flickering chandeliers tonight. Mara's flashlight revealed a crimson stain on the Persian rug, spreading slowly, as if the blood itself breathed in silence. The clock's ticking clock seemed to accelerate, each second echoing louder than the previous, urging urgency upon the investigator now. Outside, a lone wolf howled, its mournful cry mingling with the wind, hinting at secrets buried beneath the estate's shadows.
