The old manor loomed darkly under stormy midnight skies. Rain lashed windows as thunder shook the crumbling stone walls. A lone figure stumbled through the overgrown, twisted garden path. Footsteps echoed hollowly on the cracked, rain-slicked flagstones below. The front door creaked open with a slow, sinister groan. Inside, flickering candlelight revealed a body sprawled motionless. Blood pooled darkly beneath the victim’s lifeless, outstretched hand. A single playing card lay face-up near the corpse’s cold fingers. The detective arrived just as the first police officers rushed inside. Whispers of betrayal and secrets filled the chilling, damp air.
