The heavy rain hammered against the dark library windows while Arthur lay perfectly still upon the expensive Persian wool rug. A single silver letter opener protruded from his chest, gleaming under the golden light of the flickering crystal chandelier above. The mahogany door creaked open slowly, revealing a tall, shadowy figure who stood silently watching the cooling body with interest. Lightning flashed across the gloomy room, illuminating a bloodied glove left discarded near the fireplace where embers died away slowly. Whoever had committed this foul crime tonight had certainly left behind enough evidence to ensure an arrest by dawn arrived.
