The old mansion loomed darkly under stormy midnight skies. Rain lashed against the cracked windows, echoing hollowly inside. Footsteps crunched softly on the gravel drive below. A single lantern flickered weakly near the front door. The air smelled of damp earth and something faintly metallic. A shadow moved swiftly past the broken glass pane. Someone had entered through the shattered window last night. The housekeeper found the front door unlocked this morning. Her husband’s body lay sprawled on the marble floor. A single playing card rested beside his cold hand.
