The moonlight silvered the cold stone floor while the heavy scent of bitter almonds choked the stagnant, frozen midnight air. Lord Harrington lay slumped across his mahogany desk, a crimson stain spreading slowly like ink upon a crisp white page. His glassy eyes stared vacantly at the locked library door as if he were silently begging for some divine intervention. A single shattered clock rested near his limp hand, its golden gears frozen forever at the stroke of twelve tonight. Somewhere in the shadows of the velvet curtains, a floorboard creaked under the weight of an unseen, silent, murderous guest.
