The rain hammered against the dusty window while Victor stared blankly at the cold corpse resting upon the mahogany desk. A single crimson stain began to spread across the crisp white shirt showing exactly where the fatal strike had landed. Silence filled the opulent library as the grandfather clock ticked away the final seconds of a life cut far short. He touched the handle of the silver letter opener, feeling the sharp steel bite into his own trembling, pale hand.
