The heavy velvet curtains muffled the sound of the pouring rain against the cracked glass of the old mansion windows. Lord Harrington lay motionless upon the Persian rug while a crimson stain expanded slowly across his pristine white silk shirt. Nobody heard the final stifled gasp that escaped his lips before the grandfather clock chimed midnight in the empty hallway. A silver letter opener glittered under the moonlight, its sharp edge covered in a dark layer of thick, cooling blood. Footsteps echoed down the corridor, but the person wearing those heavy leather boots did not stop to help the victim.
