Rain lashed against the tall, arched windows of the grand manor as Lord Harrington poured a glass of amber whiskey. He did not notice the shadowy figure creeping silently across the thick, velvet rug toward his mahogany writing desk tonight. A heavy, brass candlestick crashed downward with brutal precision, shattering his skull and ending his prosperous life in a second. Blood seeped rapidly into the intricate floral patterns of the expensive carpet, turning the vibrant red dyes permanently crimson. The mysterious killer wiped the dripping weapon thoroughly using a silk handkerchief, then slipped away undetected into the stormy dark. Outside, lightning illuminated the desolate courtyard just as the grandfather clock chimed midnight, signaling a terrible new mystery beginning.
