Heavy rain lashed against the cracked stained glass windows of Blackwood Manor while a frozen corpse sat near the fireplace. Lord Harrington gripped an antique silver goblet within his cold hand, completely unaware of the bitter poison coating the rim. Inspector Vance stepped quietly across the threshold, shaking raindrops from his heavy coat before carefully examining the silent, shadowed room. A single crimson chess piece rested upon the velvet tablecloth, suggesting that someone had orchestrated a very deliberate, lethal game. Outside, the grandfather clock struck midnight, echoing through empty corridors where a ruthless killer still lurked in the damp darkness.
