The old manor loomed darkly under stormy midnight skies. Rain lashed against cracked windows as thunder shook the walls. A single candle flickered weakly on the dusty table. Footsteps echoed through empty halls where silence once reigned. The victim’s body lay sprawled near the grand piano. Fingers stiffened around a shattered music sheet’s edge. Blood pooled darkly beneath the victim’s frozen, wide eyes. A half-drunk glass of whiskey sat untouched beside them. The door creaked open, revealing a shadowed figure’s approach. No one had heard the killer’s stealthy, silent tread.
