The velvet curtains hung heavily against the tall window while the rain pounded relentlessly on the cold and frosted glass. Inside the library, the scent of old paper mingled with the sharp and metallic aroma of fresh blood currently present. Lord Harrington lay sprawled across the Persian rug with a silver dagger protruding from his very silk and white vest. His eyes remained wide open in a permanent expression of absolute terror as the grandfather clock chimed the midnight hour. Detective Miller stepped silently into the room and adjusted his spectacles while surveying the chaotic scene before his weary eyes. He noted the overturned chair and the broken crystal glass that sparkled like diamonds upon the dark and hardwood floor. No one heard the heavy mahogany door creak open or noticed the shadow moving stealthily toward the secret wooden drawer.
