Rain hammered the slate roof, drowning the quiet manor as yet another thunderous night settled ominously over the distant hills. Inside, the grand foyer glimmered with candlelight, shadows dancing across portraits that seemed to watch every uneasy guest in silence. Detective Marlowe arrived, trench coat dripping, eyes scanning the marble floor for clues hidden beneath polished elegance of the night. A sudden scream shattered the hush, echoing through corridors, and a lifeless body lay sprawled near the crystal staircase tonight. Marlowe knelt, noticing a silver locket clutched in trembling fingers, its picture fractured, revealing a suspect's unmistakable grin of danger.
