Rain hammered the cobblestone streets as midnight bells tolled softly. Detective Marlowe entered the manor, his coat dripping with purpose. Inside, a chandelier flickered, casting shadows over shattered glass on. The body lay sprawled, a stain blooming beneath the rug. Marlowe knelt, noticing a silver cufflink glinting beside the corpse. A wind whispered secrets through the cracked windows, urging investigation.
