Cold rain tapped violently against the heavy stained glass window. Inside the library, shadows stretched across a pale, lifeless hand. Lord Harrington slumped awkwardly beside his favorite antique writing desk. Dark crimson blood dripped slowly onto the expensive Persian carpet. A silver letter opener remained embedded deep within his chest. The grandfather clock struck midnight with a dull, hollow groan. Evelyn dropped her brass lantern when she saw the carnage. Footsteps faded down the hallway before she could even scream.
