The old Victorian house stood silent beneath moonlight’s cold, pale glow. Rain tapped rhythmically against the windows, echoing through empty halls. A single candle flickered weakly on the grand piano’s polished keys. Footsteps echoed softly down the creaking staircase, though no one remained. The front door creaked open, revealing a shadowy figure in the doorway. A chilling whisper slithered through the air, making gooseflesh rise instantly. The victim’s body lay sprawled across the marble floor, blood pooling darkly. A silver pocket watch ticked loudly, its hands frozen at exactly eleven. The detective arrived just as the first police officer stepped inside cautiously. Fingers trembled as they lifted the victim’s limp, cold hand gently. A note slipped from the pocket, its ink smeared with something darker. The house seemed to hold its breath, waiting for answers desperately. Every surface bore traces of a struggle, though no weapon was visible. The detective’s sharp eyes scanned the room, searching for hidden clues. A faint scent of lavender lingered, clashing with the metallic stench. The killer’s identity remained a mystery, wrapped in shadows deeply. The night stretched on, its secrets whispering through the stillness.
