The mahogany clock chimed seven, a hollow sound. Doctor Alistair found him slumped over his desk. A letter opener protruded from Marcus Webb's chest. Rain streaked the window like tears of shattered glass. The study smelled of blood and old rosewater. A single playing card lay near the victim's hand. It was the ace of spades, perfectly centered. No forced entry, no struggle, just silent, violent precision. The doctor's breath caught, a sharp, shallow intake. Thunder rolled, as if sealing the scene's grim truth.
